Motion PASSED 6-0. Added Items, Communications, Notice of Upcoming Meetings None ZCA-2008-2 Flood Hazard Regulations KCC Section 14.09 Environmental Engineer Beth Tan stated that staff is pursuing changes to the City's Flood Plain Regulations as the result of a meeting with a Federal Emergency Management Agency (FEMA) representative who found language lacking within the Kent City Code, 14.09. Tan stated that updating Kent City Code (KCC) Section 14.09 at this time, will allow the City to enter into a "Community Rating Systems Program", and enable the City to obtain a discount for home and property owners located within Kent's Flood Plain area. She stated that since the time of the 1995 map, FEMA has drafted a preliminary digital flood insurance rate map which expands the flood plain boundaries within Kent. Tan reported on proposed amendments to specific sections of KCC 14.09; citing changes to Section 14.09.060 which establishes special flood hazard areas. Tan cited changes to Section 14.09.150 which designates the local administrator and the floodways (referenced under Section 14.09.180). Tan cited Section 14.09.170, explaining why staff recommends that residential structures be built a minimum of two (2) feet above the base flood elevation. She stated that if Kent receives a discounted insurance rate, the cost to raise a residential structural one extra foot would be paid for within three years due to the insurance discount the residents receive. Tan stated that Section 14.09.175 Compensatory Storage has been deleted from the City's Surface Water Design Manual (SWDM) and incorporated into KCC as a new section that will aid in regimenting and funneling the administrative variance process through the Hearing Examiner. Tan stated that staff is using a 1995 flood map along with a preliminary map that FEMA has developed under Kent's current city code. She stated that Kent has filed Land Use and Planning Board Minutes January 12, 2009 Page 1 of 3 2 an appeal map along with other jurisdictions in the County. She stated that staff recommends incorporating the definitions "best available data" and "or any revision thereto" within the flood hazard regulations to avoid the need to pursue code revisions at a later time after the appeal process has ended and FEMA has released their final version of the map. Tan spoke about the 1995 Flood Insurance Rate Map, and the 2007 Preliminary Digital Flood Insurance Rate Map (FEMA's original proposal for Kent's flood plain) covering the area from valley wall to valley wall. Tan described how Kent appealed FEMA's 2007 Flood Insurance Rate Map through a complex engineering process. She stated that a larger extent of Kent would be located within the flood plain. Tan displayed aerial photos of several areas of flooding in Kent taken by staff on January 9. Tan stated that after tonight's hearing, staff would like to take this issue to the January Public Works Committee meeting and to City Council for approval in February. Tan stated that these changes must be implemented in February in order for Kent to receive approval for its CRS application and 20 percent discount in October 2009. If this deadline is not met, staff will look at completing the application in April 2010. In response to Ottini, Tan stated that structures must be built to the standards of whatever flood insurance rate map is current at the time of construction, and would not affect those structures insurance rates in the future, were the map updated with more restrictions, as those structures would be governed under the older map. Tan stated that people are not restricted to a two-foot height minimum and expressed that it is her understanding that there are some Federal Programs that provide grant monies for those people residing in a flood plain who wish to pursue raising their home's elevation. Chair Johnson declared the Public Hearing open. Elizabeth Albertson, 304 Summit Ave N, Kent, WA 98030 stated that she resides half-way up the hill between James and Smith and serves on Kent's City Council. She stated that she is interested in knowing where Kent is going to establish their flood hazard plain area, as she experienced flooding in her home following the heavy rain storm and feels that the flood plain should be bigger than just telling people they must build their structures higher. Ottini opined that Albertson's flooding might be the result of rain water runoff conducted through a clay bank that runs through the hill. He stated that Kent would not be able to acquire insurance if flood plain boundaries were drawn 30 feet up the hill. Seeing no further speakers, Ottini Moved and Gray Seconded a Motion to close the Public Hearing. Motion CARRIED. Land Use and Planning Board Minutes January 12, 2009 Page 2 of 3 3 Ottini Moved to adopt ZCA-2008-2 Flood Hazard Regulations as proposed by staff along with amendments to add and delete specific language as presented at the meeting of January 12, 2009.

Kent, WA 98032-5895 February 17, 2009 TO: Chair Jon Johnson and Land Use and Planning Board Members FROM: Mike Gillespie, Development Engineering Manager RE: Design and Construction Standards (ZCA-2008- 3) For the February 23, 2009 LUPB Public Hearing BACKGROUND: On February 9, 2009 Public Works Development Engineering discussed with the Land Use & Planning Board proposed changes to the City's Design and Construction Standards. The Standards have not been comprehensively updated since 1993, with the exception of minor modifications as approved by the Public Works Director. Over the past two years, staff has worked to complete a thorough review and update of the standards and details, and has finalized a complete draft of the standards. SUMMARY: The Design and Construction Standards are utilized by both City staff and private design professionals when designing projects for construction in the City of Kent. They provide the accepted processes and methods to be used for public and private infrastructure. Over the past two years, staff has worked to revise the previous standards and details. A preliminary draft was made available to internal staff in November 2007, where 1200+ comments were received. Staff incorporated those comments into the draft, and did additional research into new techniques. A second draft was released in October 2008 with two focus groups held for members of the development community and design professionals, and an internal staff focus group. We have considered all comments and finalized a complete draft of the standards. We are presenting the final draft to the Land Use and Planning Board on February 23rd for the Public Hearing before the Board. Staff will be available at the Hearing to further discuss this issue. RECOMMENDATION: Staff recommends adoption of the Design and Construction Standards.

C-1 Appendix D: Engineer Cost Estimate Forms.....................................................D-1 x 19 POLICY AND PURPOSE The City of Kent has adopted these Design and Construction Standards (Standards) for two primary reasons: 1. To the extent practicable, to set forth the minimum requirements for specific and consistent requirements for construction of and improvements to public and private streets, water utilities, sewer utilities, and storm water utilities, placement and operation of any utilities in rights-of-way and all excavation and grading in the City. These Standards include procedures for inspection, acceptance, warranty and deviations. 2. To establish uniform criteria to guide the City's own design, construction and improvement of City streets and utilities. These Standards are crafted to enable the City to achieve goals for neighborhood and transportation connectivity transportation safety, affordable housing, storm water management, environmental protection, and cultural resource enhancement in balance with sound and efficient Development. With respect to transportation, the City requires consistent Standards to assure, so far as practical, that motoring, bicycling, transit, and pedestrian public safety needs are met in compliance with requirements for safety, convenience, aesthetics, surface water drainage, economical maintenance, and cultural and environmental resource protection. Because the City must have flexibility to carry out its paramount duty to provide for the diverse and changing needs of the traveling public, these Standards are not intended to represent the legal standard by which the City's duty to the traveling public is to be measured. These Standards cannot provide in detail for all situations. They are intended to guide, but not to substitute for, competent work by licensed professional surveyors, architects and engineers. The City recognizes that these professionals must use their best judgment and skill in design and construction decisions, and must consider many factors including, but not limited to, environmental constraints, existing geometry and sub-surface conditions. For its own projects, he City faces the additional factor of limited economic resources which are constrained by limits upon taxing authority. These Standards are not intended to be so inflexible as to limit the economies of lower impact development alternatives or other innovative or creative designs that could result in equivalent or improved safety, quality, and maintainability. At the same time, environmental conditions may require more limiting design parameters than would be otherwise required by these Standards. Any proposed deviation from the Standards will be evaluated as to the likelihood that such deviation will produce a compensating or comparable result as would the application of the original standard under typical conditions and be, in every way, safe and adequate for the public. The final decision on any proposed deviations will be made by the Deputy Public Works Director/City Engineer or his or her designee (hereinafter"Engineer"). This document does not require that existing facilities not subject to any public or private Development be rebuilt to comply with these Standards, but the Engineer reserves the right to require upgrades in any particular circumstances where warranted and as required by applicable law. P-1 20 This page intentionally left blank. P-2 21 1.0 GENERAL CONDITIONS AND REQUIREMENTS 1.1 General These Standards are the general conditions and requirements for all improvements to or extensions of the City of Kent's street, storm drainage and utility systems. The conditions as stated herein, and in the City of Kent Surface Water Design Manual, apply to all improvements made by public agencies, Utilities, and private Developers. Please note the following conventions. As a rule, capitalized nouns will be defined in Section 1.18, Definitions and Abbreviations. For the sake of efficiency, the term "Developer" means any person or entity designated or named in writing by the property or easement owner to be the Applicant, or a public agency or Utility which owns a Right-of-Way or Easement in a permit application or approval for a development proposal or capital improvement project. Developer also includes a Permit Applicant, one who has already been granted a Permit, and the City itself for those situations where City construction activities are subject to approval under the particular Standard. While the City will be guided by the Standards as noted herein, the City does not grant or require permits or Financial Guarantees for its own Work. 1.2 Applicability These Standards shall apply to all newly constructed street, utility, and right-of-way facilities and improvements, public and private, within the City of Kent. The Standards apply to modifications of street features or existing facilities which are within the scope of reconstruction, widening or narrowing, required off-site street improvements for land Developments, or capital improvement projects when so required by the City, or to the extent they are expressly referred to in the Kent Comprehensive Plan and associated subarea plans. The Standards shall apply to every new placement and every planned, non- emergency replacement of existing utility poles, underground facilities, and other utility system structures within the City Right-of-Way. Every effort shall be made to meet the Standards during emergency replacements. 1.3 Severability If any part of these Standards as adopted by ordinance shall be found invalid, all other parts shall remain in effect. 1.4 Changes to this Manual The Engineer may incorporate minor changes to these Standards as they become necessary. Major, substantive changes shall include an opportunity for public review and comments and adoption by ordinance. 1-1 22 1.5 Responsibility to Provide Street Improvements Developers for Projects meeting one or more of the thresholds listed below shall construct street improvements, including pedestrian and bicycle facilities, in accordance with these Standards: 1.5.A Land Development Impacts Any land Development, which will impact the service level, safety, or operational efficiency of any City streets serving such land Development or is required by other City code or ordinance to improve such streets. Off-site street improvements shall be based on an assessment of the impacts of the proposed land Development by the Engineer. 1.5.13 Land Development Abutting Existing Streets Any land Development abutting existing public streets. The extent of improvements shall be based on an assessment of the impacts of the proposed land Development by the Engineer. 1.5.0 Land Development Containing Internal Streets Any land Development that contains internal streets. Unless otherwise approved by the Engineer, the internal streets shall be constructed in compliance with these Standards. 1.6 References All references herein shall be to the editions or versions in effect at the time a complete application for the required Permit is accepted by the City, unless a Developer is otherwise vested by applicable law. 1.6.A General References The Standards are intended to be consistent with the following Codes, Plans, Programs, Manuals, Guidelines, Laws and regulations. 1.

See Appendix C for sample real estate documents. 1.11 Transfer of Ownership of Improvements All improvements, including but not limited to pavement, utilities and storm water facilities, shall be conveyed to the City by an itemized Bill of Sale. See Appendix B. Under no circumstances will a Bill of Sale be placed on the City Council agenda for action after until all easements have been approved by the Engineer and recorded, and all Infrastructure Improvements set forth in the Engineering Plans or otherwise required by the City have been completed and finally accepted by the City. 1-10 31 1.12 Financial Guarantees All Financial Guarantees shall be on forms provided by the City and with sureties registered with the Washington State Insurance Commissioner or other Financial Institutions acceptable to the City. See Appendix B for sample forms. 1.12.A Plat Guarantees All work shown on the approved Engineering Plans should be completed prior to plat recording. Provided, however that, the Engineer may allow recording prior to the completion of all Work so long as such completion is guaranteed by performance bond in amount equal to one hundred and fifty per cent (150%) of the Engineer's estimate for the completion of the Work. Recordation will not be allowed, in any event, unless all surveying and monumentation is complete. 1.12.13 Performance Guarantees for Work in Right-of-Way As a condition of the applicable Permit, the timely, complete and faithful performance of all construction work on City Right-of-Way (either maintained or unmaintained) or stormwater tracts shall be, guaranteed in an amount to be calculated at one hundred and twenty five per cent (125%) of the Engineer's Cost Estimate. See Appendix B Forms. Fifteen per cent (15%) of the Guarantee or five thousand dollars ($5000), whichever is greater, shall be in the form of an Assignment of Funds. The balance may be by Performance Bond, Irrevocable Letter of Credit or, in the alternative; the entire Guarantee may be in the form of an Assignment of Funds. Developers with a history of corrections or defaults must provide the full Guarantee by Assignment of Funds. 1.12.0 Maintenance Guarantees Maintenance and the successful operation of the right-of-way improvements or related drainage facilities shall be warranted for a period of at least two years (or other period as required by Kent City Code) from the date of Final Construction Approval. The warranty shall be guaranteed in an amount to be determined by the Engineer. The minimum Maintenance Guarantee shall be five thousand dollars ($5000.00) or twenty per cent 20% of the original performance bond, whichever is greater. The forms of the Guarantee shall be as set forth in Subsection 1.12.B herein. At 6-month intervals during this maintenance period, the City will inspect the improvements and identify to the Developer any noted deficiencies. The Developer will have thirty days to correct any deficiencies. The satisfactory correction of the Work may commence a new two year maintenance period for the improvements as corrected as determined by the Engineer. The City will initiate collection against the Financial Guarantee if deficiencies are not satisfactorily addressed by the end of the thirty-day response period. 1-11 32 1.12.113 Site Restoration Guarantees For Grade and Fill permits, the completion and performance of all stormwater and erosion control measures shall be guaranteed for a period of at least one year (or other period as required by Kent City Code) from the date of Final Construction Approval. The amount of the Site Restoration Guarantees shall be determined by the Engineer. The forms of Site Restoration Guarantee shall be as set forth in Subsection 1.12.13 herein. In addition to foreclosure for failure to perform the terms of the permits, the City will foreclose on the Financial Guarantee and utilize the funds to reduce drainage impacts and permanently stabilize the Site in the event that the City determines that the Site has been abandoned. The City will consider a Site to be abandoned based on the absence of response by the Developer to correct noted deficiencies or failure to complete improvements prior to permit expiration. Permanent stabilization includes, but is not limited to, reclamation of the Site if a Project is abandoned after construction or Excavation has commenced. 1.12.E Reduction/Release of Financial Guarantees Original Financial Guarantee amounts may be reduced one time only prior to the maintenance period, at the discretion of the Engineer. If an extension to the associated Permit is granted, the Financial Guarantees may be increased based on an updated Engineer's Cost Estimate or as determined by the Engineer. In no event will the fifteen per cent (15%) required Assignment of Funds, pursuant to section to 1.12.13, be released prior to Final Construction Approval. Financial Guarantees will be fully released only after all final punchlist items are accomplished, Final Construction Approval, and the elapse of the two- year Maintenance Guarantee period with all corrective actions complete and accepted by the City. 1.13 Responsibility of Developer The Developer is responsible for completing all Work and Infrastructure Improvements in full compliance with the approved Engineering Plans The Developer shall furnish all labor, materials, tools, equipment, transportation, necessary supplies and incidentals required to make each and every item complete as documented by said Engineering Plans. All Financial Guarantees shall show the Developer as the Obligor and the City as Obligee. Developer shall be held responsible for the actions or omissions of any agents, heirs, assigns or contractors. 1.14 Revisions or Additions after Approvals A Developer may seek revisions or additions to the Engineering Plans after approvals for good cause shown, at the discretion of the Engineer. The Engineer may require revisions or additions to Engineering Plans upon his or her initiative. Revisions must be presented through revised plans to be reviewed and approved by 1-12 33 the Engineer before work under the Plans is undertaken. Revisions in the Engineering Plans and other associated documents shall have the same force and effect as if contained in the original approved Engineering Plans and documents. Associated permits will be amended and/or conditioned accordingly. The decision of the Engineer in this regard shall be final. 1.15 Control of Work 1.15.A Authority of Engineer Work included in the Engineering Plans and related documents are to be done to the complete satisfaction of the Engineer. The decisions of the Engineer as to the construction and intent of the approved Engineering Plans and estimates and as to all questions arising as to proper performance of the Work shall be final. The Engineer shall decide any and all questions which may arise as to the quality or acceptability of materials furnished and work performed. Nothing contained in this Chapter shall be construed as requiring the Engineer to direct the method or manner of performing any work under this Chapter. However, the work in progress shall be open to inspection by the Engineer at all times. The Engineer may appoint staff engineers and inspectors to review Engineering Plans, inspect the materials used and the work performed and may otherwise delegate authority as is appropriate. 1.15.113 Authority and Duties of Inspectors The Engineer will assign Inspectors to inspect all materials used and all work performed.

It is emphasized that no work may be started until such plans are approved by the City. Any revision to such Engineering Plans shall be approved by the Engineer before being implemented per Section 1.14, Revisions or Additions after Approvals. Any improvements by other water and sewer providers other than the City shall be designed and approved by the Utility with copies provided to the City prior to approval of the Engineering Plans. The Engineer is authorized to enforce these Standards as well as other referenced or pertinent specifications or guidelines. He/she will appoint project Engineers, assistants, and Inspectors as necessary to inspect the Work and they will exercise such authority as the Engineer may delegate. Provisions of Section 1-05 of the WSDOTWSDOT Standard Specifications shall apply, with the term "Engineer" therein construed to be the Engineer as defined in these Standards. 2.2 Inspection Generally, on all privately developed infrastructure including street, utility, and drainage system construction proposed or in progress by a private developer, control and inspection will be done by the Construction Management Section on behalf of the Engineer. The Engineer must approve any deviations from the Standards during construction as described herein. The Developer is ultimately responsible for quality control of construction and the assurance of meeting these Standards. Public Works inspectors monitor these activities with enforcement authority when requirements are not met. All materials provided by the Developer shall be subject to inspection and approval by the Inspector at any time during the progress of work until Final Acceptance. The contractor's construction schedule shall include sufficient time for materials testing and any required verification by the Inspector. The Inspector may advise the Developer or contractor of any faulty work or materials; however, failure of the Inspector to advise the Developer or contractor does not constitute acceptance or approval. At the Inspector's order, the Developer and/or contractor shall immediately remedy, remove, replace, and dispose of unauthorized or defective work or materials and bear all the costs of doing so. All street, utility and drainage system infrastructures must be inspected. Subgrade inspection will not commence until density tests confirm that the Compaction is in accordance with the specifications. 2-1 54 2.2.A Minimum Requirements Prior to beginning any critical task, the Developer must schedule meetings and/or inspections, in advance, with the Inspector. At a minimum, the following critical tasks require advance notification 1. Pre-Construction Conference: Five working days prior notice unless otherwise approved by the Engineer. Conference must precede the beginning of construction and include the Developer, contractor, design engineer, utilities, and other applicable participants. Engineering Plan approvals and Permits must be issued prior to the scheduling of the conference. 2. Clearing and Temporary Erosion/Sedimentation Control: One working day notice prior to initial Site work involving drainage and installation of temporary erosion/sediment control. See Section 5.7 Erosion Control for additional information. 3. Utility and Storm Drainage Installation: One working day notice prior to trenching and placing of storm sewers and underground utilities such as sanitary, water, gas, power, telephone, and TV lines.

Prior to release of the maintenance Financial Guarantee, there shall be successful completion of the maintenance period as described in Section 1.15.1 Maintenance Period and Final Inspection of All Public Improvements, replacement/repair of any failed facilities, and the payment of any outstanding fees. 2.2.B Penalties for Failure to Notify and Obtain Approval Notification by the Developer or the contractor, at the necessary time frames noted above, is essential for the City to verify, through inspection, that the Work meets these Standards. Failure to notify and obtain approval will result in the City requiring additional materials sampling and testing by a materials testing laboratory. Costs of such testing and certification shall be borne by the Developer. If the test results conclude that the unauthorized work doesn't meet these Standards, the Developer will be required to remove the unauthorized material and replace it with materials that meet the Standards at his/her own expense. At the time that such action is directed by the Engineer, further work on the Development may be limited or prohibited until all directed tests have been completed, approved, and all corrections identified by the City have been made to the satisfaction of the Engineer. If necessary, the City may take further action as set forth in Kent City Code 2.3 Control of Materials 2.3.A Source of Supply and Quality of Materials The Developer shall notify the Engineer of proposed sources of supply for all materials to be furnished. At the option of the Engineer, the source of supply of each of the materials shall be approved by the Engineer before the delivery is started. Representative preliminary samples or test data of the character and quality prescribed may be required to be submitted by the Developer or producer for examination by the Engineer. Only materials conforming to the requirements of the WSDOT Standard Specifications and approved by the Engineer shall be used in the Work, see Section 1-06.1 of the WSDOT Standard Specifications. Any of the materials proposed to be used may be inspected or tested at any time during their preparation and use. If, after testing, it is found that sources of supply which have been approved do not meet the specifications or if the product from any source proved unacceptable at any time, the Developer shall furnish approved materials from other approved sources. No materials which, after approval, have in any way become unfit for use shall be used in the Work. 2-3 56 Materials shall be delivered, in advance, on the Site in such quantities as to afford the Engineer an opportunity to make tests before the materials are to be used. 2.3.113 Samples and Tests At the direction of the Engineer, the Inspector shall direct that a materials testing laboratory be utilized to conduct necessary field and/or lab tests of materials or methods. All testing shall be done in accordance with ASTM and AASHTO accepted standards and all reports shall be stamped and signed by a Professional Engineer. Such test/laboratory reports shall be transmitted to the Inspector by the Developer and shall be the basis upon which decisions may be made for the Developer to proceed with certain portions of their work. The absence of adequate materials testing reports may delay or prohibit work from proceeding. In such cases the City shall not be responsible for Developer delays. All testing shall be in accordance with commonly recognized standards of the appropriate national organizations, WSDOT, ASTM, AASHTO, or common industry standards. The field tests of materials shall be made as deemed necessary by the Engineer at no cost to the City. In general, tests shall be made at the frequency as outlined by the applicable sections of the WSDOT Standard Specifications. The Developer shall furnish, without charge, samples of all materials as requested by the Engineer. Materials shall not be used until approved. The Developer shall furnish, at their own expense, such labor and facilities as may be required to enable the Engineer to make a thorough inspection of the materials. A Certificate of Materials shall be provided. As soon as materials have been tested and inspected, the Developer shall immediately remove all rejected materials from the Site as the Engineer may require, and shall arrange for replacement of rejected materials at their own expense. The neglect or failure on the part of the Engineer to reject inferior materials or work shall not be construed as an acceptance of the materials or work. 2.3.0 Storage of Materials All materials intended for use in the Work shall be stored by the Developer by means that will prevent damage from exposure to the elements, Erosion, contamination from admixture of foreign materials, or from any other cause. The Engineer will refuse to accept, or to sample for testing, any materials that are improperly stored. The Engineer may inspect materials when, in the opinion of the Engineer, the materials no longer meet specifications. If materials are found not to meet specifications, they shall be removed immediately from the Project site. 2-4 57 2.3.D Defective Materials All materials not conforming to the requirements of these specifications and the approved plans will be rejected by the Engineer and all such materials whether in place or not, shall be immediately removed from the Site of the Work by the Developer. 2.3.E Temporary Stockpiling A temporary stockpile consists of materials such as Fill material, unsuitable Excavation, or aggregate that is stored in piles of varying size awaiting use or disposal on a public or private Project. No contaminated stockpiles shall be allowed within the City of Kent unless associated with an Ecology-approved clean up plan or as otherwise approved by the City of Kent. Temporary stockpiles are allowed within public or private Project limits subject to the requirements below. All stockpiling activities on privately owned property adjacent to or in the vicinity of a Project shall be subject to the Grading requirements of KCC 14.01.030A and these Standards. In addition, stockpiling of more than 500 CY throughout the total lifetime of the Fill or Excavation shall be subject to SEPA regulations per KCC 11.03. All of the following requirements shall be met while temporarily stockpiling material: 1. All proposed stockpile locations must be shown on the Temporary Erosion and Sediment Control plan sheets or otherwise approved by the Engineer. 2. Locate temporary stockpiles a minimum of 50 ft away from sensitive area buffers, concentrated flows of stormwater, drainage courses, and/or inlets. This 50 ft restriction may be reduced based on a Site specific TESC plan that addresses BMPs for protecting the stockpile and as approved by the Engineer. 3. Protect all temporary stockpiles from wind and stormwater Erosion using plastic sheeting installed per City of Kent Surface Water Design Manual specifications. Perimeter protection, such as vegetative buffers, silt fence, straw bale barriers, or wattles, must be used in conjunction with the stockpile covering as necessary to prevent sediment transport. 4. All temporary stockpiles shall be inspected before, based on weather forecasts and after any recordable precipitation or once a week if no precipitation occurs. 5. Temporary stockpile locations shall not block the sight distance at any Intersection or Driveway. 6. Maximum height of stockpiled materials shall be 24 feet. 2-5 58 All temporary stockpiles shall be covered and protected during the Wet Season (October 1 to March 31) if they are not being used for any 2 day period or, if during the Dry Season (April 1 to September 30) the material is not to be used for any 7 day period. During the Wet Season, slopes and stockpiles 3H: 1V or steeper with more than 10 feet of vertical relief shall be covered if they are to remain unworked for more than 12 hours. The intent of these measures is to prevent Erosion by having as much area as possible covered during any period of precipitation. Portland cement, cement concrete rubble, asphalt concrete, and asphalt concrete rubble stockpiles shall be covered at all times. All temporary stockpiles shall be removed and the area restored to its original pre-stockpiling condition prior to the Final Acceptance of the Project associated with the stockpiling need. Temporary stockpiles may not be used as Fill on the stockpile site or any other site unless specifically included, described and approved in a Permit for the Site on which it is to be used. For further reference on how to temporarily stockpile materials see Standard Plan 5-32. 2.4 Construction Control in Developments The provisions of Section 2-03 of the WSDOT Standard Specifications apply in all respects to Development construction unless otherwise instructed by the Engineer. The following elements are mentioned for clarification and emphasis: 2.4.A Embankment and Cut Section Compaction Each layer of the entire embankment shall be compacted to 95% of the maximum density per Section 2-03.3(14) C of the WSDOT Standard Specifications as determined by the compaction control tests described in Section 2-03.3(14) D of the WSDOT Standard Specifications. 2.4.B Testing for In-Place Density and Moisture Content 1. Prior to placing any surfacing material on the Street, it will be the responsibility of the Developer to provide density test reports reviewed and approved by a professional Engineer and accepted by the Inspector. It is the obligation of the approving Professional Engineer to notify the inspector of any test results that do not meet the minimum requirements of the Specifications. Optimum moisture content, maximum density, in-place density and moisture content shall be determined by methods cited in Section 2-03.3(14) D of WSDOT Standard Specifications or by other test procedures approved by the Engineer. For Work to be accepted, tests must show consistent uniform density and moisture content as required by tests referenced above. 2-6 59 2. Compaction reports are required for all Projects. The reports shall include a sketch showing the locations the tests were taken. Compaction testing shall be accomplished as Backfill or embankment construction progresses. At a minimum, compaction tests are required at the following locations. Additional tests and/or shorter length intervals may be required by the inspector. a. Embankment: In Fill sections, every 1,000 cubic yards or fraction thereof on each lift of Fill. In Cut sections, once for every 100 linear feet or 500 square yards, whichever results in a greater number of tests. b. Trench lines: At 150' intervals (or between structures if less than 150') and for every 2' depth of material placed or as required by the Engineer. c. Street subgrade: At fifty 50' intervals. d. All curb and gutter locations: At 150' intervals, each side. e. Crushed Surfacing: At 100' intervals. f. All sidewalk, pathway and/or bikeway locations: At 150' intervals, each side. g.

In cases where tests or frequency of testing do not meet the minimum standard, corrective action shall be taken as directed by the Developer's Engineer and approved by the Inspector. Retests shall show passing densities prior to placing the next lift of Fill or pavement. 2.4.0 Unsuitable Foundation Excavation The contractor shall excavate unstable natural ground before building any embankment over it or in trenches for storm drainage and utilities. This unstable material may include peat, muck, swampland, buried logs and stumps, or other material not fit for a base. If unsuitable material is encountered, the Developer and/or contractor shall immediately contact the Inspector. No Fill, Backfill or permanent parts of a structure shall progress until authorized by the Inspector. Corrective actions may include, but are not limited to, over excavation, dewatering and/or development and approval of a special design section. The contractor shall excavate such material to the boundaries set by the Inspector. 2.5 Subgrade In preparing the roadbed for surfacing before any paving, the requirements outlined in Sections 2-06.3(1) and 2-06.3(2) of the WSDOT Standard Specifications shall be met. After the subgrade preparation has been completed, it shall be 2-7 60 thoroughly checked by the Developer and/or contractor using a level, laser level string line, crown board, or other means to determine that the subgrade conforms to the approved street section and these Standards prior to placing any surfacing material. 2.6 Traffic Control in Development Construction 2.6.A Interim Traffic Control The Developer shall be responsible for interim traffic control during construction on or along traveled City streets, including grade and fill operations which exceed haul route requirements and work on private property where trucks and equipment are entering and exiting the Site on a daily basis. See Section 6.12.0 Construction Area Traffic Control. When Street or drainage work is to be performed on City streets that are open to traffic, the Developer will be required to submit a traffic control plan for approval by the Engineer prior to approval of the plans unless otherwise approved by the Engineer. In no case shall construction begin until the traffic control plans have been approved. Traffic control shall follow the guidelines of Section 1-07.23 of the WSDOT Standard Specifications. All barricades, signs and flagging shall conform to the requirements of the MUTCD Manual. For more specific requirements, see Section 6.12 Traffic Control Devices and Standard Plan 6-72. Signs must be legible and visible and shall be removed at the end of each workday if not applicable after construction hours. 2.6.113 Temporary Street Closures and Detours When temporary street closures cannot be avoided the Developer and/or contractor shall post "This Street Will Be Closed" signs a minimum of 10 working days prior to the closing and after approval of closure by the City. The types and locations of the signs shall be shown on a detour plan. A proposal for a street closure and a detour plan must be prepared and submitted to the Engineer at least 10 working days in advance and approved prior to closing any City Street. In addition, the Developer and/or contractor must notify, in writing, all adjacent property owners and/or tenants, local fire, school, and law enforcement authorities, Metro transit, and any other affected persons as directed by the Engineer at least 10 working days prior to closing.

Easements shall be provided by the Developer for all public water system infrastructure including the pipe, valves, backflow preventers, etc. Whenever an Easement or Right-of-Way is fenced, a gate shall be installed matching the width of the Easement and a City of Kent lock must be placed in "series" to facilitate access by the City. When easements are required, legal descriptions shall be prepared by a Professional Land Surveyor licensed by the State of Washington. A title report, dated within 30 days, covering the properties to be encumbered by the easements shall accompany the description. When off-site and/or on-site easements for the extension of approved comprehensive water plans are required, these easements shall be approved and recorded by the City before any Civil Construction Permit is issued unless the easements are being dedicated to the City as a part of the recorded final subdivision. Private improvements such as buildings, fences, garages, carports, retaining walls, utilities, signs, light standards, etc., are not allowed in public easements and rights- of-way. Water Main easements and rights-of-way are not allowed within the setbacks between two residential structures. Where an encroachment occurs, the Developer shall remove and relocate the conflicting private improvement immediately upon direction from the Engineer. 3.1.A Easement Requirements Easements shall be accessible for construction equipment normally used for the operation and maintenance of the facility. Cross slopes exceeding 5% will require a deviation approval of the Engineer. The minimum easement widths, centered on the utility system are as follows: 1. Watermain under 5' deep - 15' wide minimum 2. Watermain 5' - 9' deep - 25' wide minimum 3. Watermain over 9' deep - The formula for half of the width of the Easement shall be the sum of the total depth from the top of pipe to 3-1 64 the surface, plus the pipe diameter, plus 3', rounded to the nearest even foot. 4. Special conditions or installation requirements may require greater easement widths as determined by the Engineer. 5. In easements with multiple utility systems, the easement width shall be increased by the minimum separation distance between the lines. 6. In easements with multiple utility systems, the easement width shall be increased by the minimum separation distance between the lines. 3.1.113 Right-of-way Where feasible, the utility system extensions shall be located within the City's Right-of-Way. Work inside adjacent City, County and/or State Right-of-Way requires special permits from the respective agencies. Adjacent City, County and State permits and others must be obtained by the Developer or the City if required by franchise prior to construction Plan Approval by the City. 3.2 Standard Specifications The installation of all watermains and Appurtenances shall be in accordance with the applicable provisions of the latest edition of the Washington State Department of Health Water System Design manual (WSDOH), AWWA or WSDOT Standard Specifications. The manufacturer's recommended installation procedures should be adhered to and not conflict with AWWA or WSDOT Standard Specifications. In the event of conflict, the Engineer shall determine any exceptions to WSDOH, AWWA or WSDOT Standard Specifications. 3.3 Watermain Extension Design Requirements All watermain extensions shall conform to these Standards and the Washington State Department of Health. Main extensions are also subject to appropriate Permits and plan review fees. Contact the City's Permit Center at 253-856-5300 or see the web site at www.ci.kent.wa.us for the latest Permit fee schedule. 3.4 Comprehensive Water System Plan The Comprehensive Water System Plan (WSP) indicates the location and configuration of the major elements of the existing and proposed water supply mains, distribution system, inter-ties and loops. The exact location or configuration of this system may be modified, provided the proposed system remains consistent with the overall intent of the plan. Minor modifications to the WSP Comprehensive Plan require specific approval by the Engineer. In some instances, where existing pressures are not met or cannot be provided, as determined by the City Engineer, portions of the WSP may be the direct responsibility of the Developer/Owner to complete in order to meet the minimum development requirements. Specific 3-2 65 conditions may be placed in the Permit approval or conditions of approval for the Project. 3.5 Mainline Water Extensions Mainline Extensions will be required when the property does not front on a watermain or when the existing main is deemed inadequate for the proposed use. The extension shall be in accordance with the latest adopted Water System Plan and these Standards. The watermain must be extended to the far edge of the property to be serviced, as approved by the Engineer, regardless of where the service connection is to be made to serve properties in the same service area. 3.6 Water System Design Standards 3.6.A Improvements and/or Alterations All improvements and/or alteration to the water system must be designed to incorporate the standards described below: 1. The desirable system working pressure shall be approximately 60-70 pounds per square inch (psi), but not less than 35 psi under Peak Hourly Demand (PHD). The minimum pressure in the water system under fire flow conditions shall be 20 psi. 2. A Pressure Reducing Valve (PRV) shall be installed and maintained on water service lines by the property owner when system pressures are in excess of 80 psi. See Standard Plan 3-13 for Service Applications up to 2" in size. 3. The minimum diameter of watermain for commercial, industrial, multi- family and residential Developments shall be 8". The size of the main in all cases must meet fire flow requirements as determined by the Fire Marshal. 4. Connections to existing watermains shall be accomplished by "extension", "wet tap" or "cut in" when mainline valves are required on the existing main. Once the new valve has been installed on the existing watermain, the City Water Section shall be responsible for placing a lock on the connecting valve and any operations. The Developer shall not operate the connecting valve for any reason. The Developer shall contact the Inspector assigned to the Project for filling or flushing of the new main, or any other need for operation of the connecting valve. No direct connection to the City's existing water system will be allowed until all purity and leakage testing results for the new water main extension have met the requirements of WAC 246.290.125.2b for purity. 5. Two cubes for "Cubing" shall be installed in the new watermain at the initial connection and at each lateral from the new watermain. The 3-3 66 Water Section shall provide the cubes which can be picked up by the Developer at the Water Section Shop located at 5821 South 240th Street. 6. Dead end mains shall be avoided whenever possible. Where dead end mains are unavoidable, a minimum 6" blowoff assembly is required. The diameter of the blowoff and tap must be sized to achieve a minimum flow of 2.5 fps in the watermain. Where cubes for "Cubing" are required in the main installation, the watermain shall terminate with a fire hydrant as long as pressures and flows meet the minimum requirements for a fire hydrant. If these requirements are not met, then a blowoff assembly shall be used. 7. The City may approve a 4" diameter "dead end" watermain for a single family residential area serving less than fifteen (15) single family residences providing the following conditions are met: a. There is no potential for a future looped system. b. The Project is not within an area of known low pressure. c. The proposed 4" diameter watermain extends or "branches" from a looped system.

There are several use applications: 3.14.A All Sources Discharged Metering When the sewer rate meter is used to meter all public and/or private sources of water discharged to the sewer, the domestic meter is changed to water use only. Deduct Meters are not used in this system. The sewer rate meter determines the sewer charges. This application is installed in two ways: 1. In a manhole, in line with the side sewer. 2. In the building water plumbing pipes at location(s) that will read all public and private water that discharge to sewer and does not include the portion used for landscape irrigation and process equipment systems that do not discharge to sewer. 3.14.113 Partial Sources Discharged Metering When the sewer rate meter is used to meter part of public and/or private sources of water discharged to the sewer and deduct meters are used to meter the uses not discharged to the sewer. The domestic meter determines water and sewer charges. The sewer rate meter is added to the sewer charges. The deduct meter(s) are deducted from the sewer charges. The meter for this type of installation is located in three ways: 1. In the building water plumbing pipes at location(s) that will pick up that portion of the public and/or private sources of water discharged to the sewer but prior to its use. 3-16 79 2. In line with the discharge pipes of processing equipment fed from the public meter prior to discharge to the building plumbing or side sewer. This water must be free of debris that could clog the meter used. 3. In line with the discharge pipes of processing equipment fed from the public meter or private source of water. This water may contain debris. 4. The sewer rate meter shall be located on private property in a location that is convenient to the Developer with a remote readout located near the City water meter as approved by the Engineer. The type of meter and remote used is subject to the approval of the Engineer and shall read in cubic feet only. The sewer rate meter requires a Sewer Permit from the City and waste discharge approval from KC/DNR-WTD. An industrial rate charge is normally added to the sewer bill for Sewer Permits with waste discharge approval as determined by KC/DNR-WTD. 3.15 Cross Connections There shall be no cross connection whatsoever between the City water distribution system and any unapproved pipes, wells, pumps, private hydrants, tanks, non- potable fluid or any other contaminating materials that may backflow into the potable water system. The City's potable water distribution system includes all City owned watermain, service pipe up to and including the meter for residential services and Appurtenances up to the DCVAs or DCVAs located after the water service meter. 3.16 Backflow Prevention The degree of public health protection required must be commensurate with the degree of hazard presented as defined in WAC 246-290. In situations of high health hazards, whether known or potential physical or toxic health hazards, air gap separation and/or reduced pressure backflow assemblies (RPBA's) shall be required. DCVAs or pressure vacuum breakers are generally utilized where low health hazard, aesthetic or detrimental effects on water quality may occur. Each water system connection has unique problems arising from location, climatic conditions, service demands, and other factors. Consequently, each cross- connection shall be evaluated on an individual basis and the City shall make the final determination as to the degree of backflow protection required. See testing and annual inspection requirements set forth in KCC 7.02.050 through 7.02.105. Backflow protection assemblies proposed for use can be found on the current list of approved assemblies by the WSDOH. All backflow assemblies are required to be tested annually by a Washington State certified backflow assembly tester. Copies of these inspection reports shall be sent to the City: Public Works Operations, Attn: Water Manager, 5821 South 240t" St., Kent, WA 98032. A separate Water Permit will be required for each backflow device installed. An annual inspection and fee will be required for each backflow device. 3-17 80 3.17 Premise Isolation Where the City determines protection of the public water distribution system is necessary, a backflow preventer shall be installed at the property line commensurate with the degree of hazard as defined in WAC 246.290.490. A sample use requiring such protection would be a medical/dental office building. Installation of air gaps shall be approved by the City based on submitted drawings in accordance with the latest edition of the City of Kent Cross-Connection Control Program Manual. Reduced Pressure Backflow Assemblies (RPBA) shall be per Standard Plan 3-14. In situations where a non-residential building has multiple tenants or the potential to have future multiple tenants, an RPBA per Standard Plan W3-14 shall be required at the property line. 3.18 Irrigation System Irrigation System Cross connection protection is required for all irrigation systems. In areas of flooding, on hillside installations, or where injection systems are used, a Reduced Pressure Backflow Assembly (RPBA) is required.

Blocking shall bear against solid undisturbed earth at the sides and bottom of the trench Excavation and shall be securely wrapped with four (4) mil polyethylene sheeting. Restrained joint pipe shall be required in areas where soils consist of peat or other low bearing strength materials or other areas as determined by the Engineer. Tie rods can be used in conjunction with thrust blocking for hydrant installations See Standard Plan 3-1 or fittings as approved by the Engineer. Mega Lugs or Mechanical Restrained Joint Pipe may be used in place of blocking only upon approval by the Engineer. 3-21 84 3.20.D Corrosive Soils In areas with corrosive soils, and at the sole discretion of the City Engineer, the watermain shall be encased in 4 mil high density polyethylene, in accordance with Method A of the most recent M41 AWWA Manual and all applicable AWWA Standards. 3.21 Connection to an Existing Water Main A physical separation between all untested and potentially contaminated watermains (or main extensions) and the City's existing water system shall be maintained at all times unless the connection is protected by an approved City and Department of Health backflow device. See Standard Plan 3-2. A hydrant meter and an approved backflow prevention device shall be used whenever drawing water from the City's water system. Hydrant meters and backflow prevention devices may be obtained from the Public Works Operations Division, Water Section located at 5821 South 240th Street. The Developer will be required to complete the billing forms for a Water Permit and making the required damage deposit. There will be a charge for all water used in accordance with Kent City Code 7.02.180 "Temporary Water Meters." Prior to the new watermain being installed, the contractor has the option of cutting in the connection tee on the existing watermain, or providing potable water from an existing hydrant or blowoff to provide a temporary water supply. If the contractor chooses the option of installing a new connection tee, the contractor shall install new resilient wedge valves on all sides of the tee, or otherwise as required by the Engineer. A mechanical joint plug with a 2" minimum tap and proper blocking shall be installed on the new incoming mainline valve at the new tee with piping accessible to accommodate filling the new water main. 3.22 Cubing Foam cubes (pigs) shall be inserted into and pushed through the new water main to remove any residue, dirt, debris, obstruction or possible foreign material in the new water main. 3.22.A Cube Usage 1. The Water Section will supply the foam cubes to the contractor based on the water system design as shown on the approved Engineering Plan. 2. The Developer shall pickup the cubes at the Public Works Operations and shall install two foam cubes at the initial connection and two foam cubes at each lateral connection 6" in diameter and larger (downstream of each connecting valve), as the new main is installed. This would include all 6"+ diameter lateral runs to hydrants that are 3-22 85 longer than one full pipe length, or have more than a single joint in them. 3. A mechanical joint cap with a 2" minimum tap shall be installed with proper blocking at the initial connection point on the new main with piping accessible to accommodate both flushing and chlorine injection. 4. The Water Section shall retrieve the foam cubes when the contractor performs the Cubing process. All Cubing and flushing shall be under the supervision of the Water Section or the Inspector. 5. To accommodate the launch and the retrieval of the cubes, the minimum blow-off size shall be 6" for watermain diameters up to 12". 6. It shall be the contractor's responsibility to properly dispose of all flush water per Section 3.23 below as well as locating and retrieving any "lost" or missing cubes or partial cubes from the watermain. 7. In the event that the initial Cubing does not adequately clean the new water mains, the contractor shall be required to provide additional point(s) for launching and retrieval of additional cubes, and re-cube those sections of main that have debris in them until clean, as determined by the Water Section. 3.23 Chlorine Injection After the Developer has cleaned the watermain by Cubing and flushing, the Developer shall inject a liquid chlorine solution evenly throughout the new main and all connections and Appurtenances for complete and optimal disinfection. The chlorine dosage shall be a minimum of 50 mg/I and a maximum of 100 mg/l. AWWA C651-99 Standards include detailed procedures for the adequate disinfection, flushing and microbiological testing of all watermains. If the Developer wishes the Water Section to do the injection, the Inspector shall give the Water Section five working days notification to perform the chlorine injection. The Contractor must sign a waiver holding the City harmless for any failure of purity samples due to the work performed by the Water Section, as well as agreeing to reimburse the City for all costs associated with the disinfection process. Work may be scheduled after hours, outside of the 5-day notification period, or refused by the City due to manpower or workload constraints. The chlorine shall remain in the main for the time specified according to the procedure used from AWWA Standards C651-99. After the 24-hour disinfection period, the remaining residual throughout the watermain and Appurtenances shall not be lower than 25 mg/L, if so it would require reapplication of chlorine. The Contractor shall be responsible for disposing of all chlorinated water. Chlorinated water shall be disposed of in an approved sanitary sewer. If a sanitary sewer is not available, or the capacity of the sanitary sewer will be at risk, the Developer shall be responsible for disposing of the water per all applicable regulations. Amount of chlorine needed to produce 50mg/L in 18' of pipe (one pipe length) for 5.25% household bleach (with no additives), 12.5% sodium hypochlorite solutions and 65% available dry calcium hypochlorite is shown in the following table. 3-23 86 Table 3.7 Diameter 5.25% al 12.5% al 65% (lb) 4" 0.009 0.005 0.007 6" 0.022 0.011 0.017 8" 0.039 0.019 0.029 101, 0.061 0.031 0.052 12" 0.087 0.044 0.047 16" 0.156 0.078 0.119 18" 0.197 0.098 0.152 24" 0.352 0.176 0.271 30" 0.548 0.275 0.422 Formula: Gals Required = (Pipe Length/18) x Disinfectant Amount Example: How many gallons of fresh 5.25% sodium hypochlorite will be required to disinfect 5,000' of 8" main? 5,000' - 18' = 278 lengths of 8" pipe 278 x 0.039 = 11 gallons required All Costs for re-injecting including the Inspector's time to come back due to "not being ready" will be the responsibility of the Developer. Costs shall be the actual costs including labor, equipment rental and materials. The costs shall be based on the latest cost schedule prepared and approved annually by the Engineer. 3.24 Bacteriological Purity Samples Two consecutive sets of acceptable purity samples, taken at least 24 hours apart, shall be collected from representative points of the new watermain, all Appurtenances and all other connections to the new watermain(s). Water section personnel will take the first bacteriological purity sample(s) after the chlorine is removed, flushing is completed and the chlorine level is no greater than, or less than, the level present in the adjacent distribution system. Water services installed prior to watermain testing shall also be purity tested with the water main and all other connections to the new watermain. The second set of purity samples shall be taken 24 hours after the first set of samples. A representative background sample of the City water system may be taken from the distribution source at the same time purity samples are taken from the new main. In the event that the Water Section or the Inspector determines that trench water, dirt or debris has entered the new main during construction, the first purity samples shall not be taken until the water has stood in the new main for at least 16 3-24 87 hours after final flushing. As above, the second set of purity samples shall not be taken until the water in the new main has stood for an additional 24 hours. No water shall be flushed during the 16 or 24 hour incubation periods described above, or prior to the purity samples being taken. It shall be the Developer's responsibility to make arrangements to transport the sample(s) to a state-certified laboratory approved by the Water Section. The Developer shall be responsible for paying all costs for the purity samples. Two consecutive samples, 24 hours apart, must show no coliform presence before performing final connections to the existing water system. The Water Section may be available during normal working hours, depending upon workload, (7:30 am to 4:00 pm) excluding holidays and weekends, to take purity samples, assist with Cubing and chlorine injections. The Developer shall reimburse the City for all associated costs including labor, overhead, equipment, and material charges. Outside of normal working hours, the Developer shall reimburse the City at the most current hourly overtime rate for labor, overhead, equipment and material charges. 3.25 Pressure and Leakage Tests All new water mains, extensions of existing mains, water system Appurtenances and water services larger than 2" shall be pressure tested for leakage in accordance with Section 7-17.3(2) of the WSDOT Standard Specifications. Water Appurtenances 2" and smaller installed prior to watermain testing shall also be pressure tested with the watermain. At no time will the temporary water system connection or backflow device remain connected or in place during the pressure test procedures. All Costs for re-testing including the Inspectors time to come back due to "not being ready" will be the responsibility of the Developer. Costs shall include labor at overtime rates, overhead, equipment, material and any other associated charges. The costs shall be based on the latest cost schedule prepared and approved annually by the Engineer. 3.26 Final Connection(s) to the Existing Water Main When both sets of purity sample results are satisfactory and received in writing from the state-certified laboratory, and all other City of Kent water system standards have been met, the Developer shall be allowed to connect the new mains to the existing distribution system following City of Kent and AWWA Standards. It shall be the Contractor's responsibility to prevent, at all times, the contamination of the new and existing watermains with trench water, dirt, debris, or other foreign material. The inspector and/or Water Section representative must be present to witness the final connection(s) to the existing water system, to turn on and flush the new water system, and to place the new water system and Appurtenances into service. 3-25 88 This Page Intentionally Left Blank 3-26 89 3.27 Water System Standard Plans 3-1 Standard Fire Hydrant 3-2 Temporary Hydrant Connection 3-3 Guard Post 3-4 Valve Marker Post 3-5 Connection to Concrete Cylinder Main (4" to 12") 3-6 2" Connection to Concrete Cylinder Main 3-7 Valve Box & Operating Nut Extender 3-8 18" or Greater Valve By-Pass 3-9 Concrete Blocking 3-10 Service Connection 1" Service 3-11 Service Connection 11/2" & 2" Service 3-12 Compound Water Meter with By-Pass 3-13 Pressure Reducing Valve with Box for 3/4 1 11/2" or 2" Service Lines 3-14 Domestic Service Connection Premise Isolation 3-15 Irrigation Service Installation 3-16 Single-Family Residential Domestic Waterline / Fireline 3-17 Multi-Family Residential Domestic Waterline / Fireline 3-18 Double Check Detector Assembly 3-19 Standard 6" Blowoff Assembly 3-20 Combination Air/Vacuum Valve & Vault 3-21 Tapping Sleeve & Valve Assemblies 3-22 Typical Pipe Trench 3-27 90 This Page Intentionally Left Blank 3-28 91 �a ¢ 129. w a m s4� o N 0 w .v :m 9:1 7 47` cdu F ?Q tu ma ua nim n 445 Y O Q V i 64., - 11101 p2p ❑a�G V i s V �� m y to Entu �ISW DSO a d �r N N q d m LL w } A,b.

The conditions apply to all improvements made by both public agencies and private developers. These improvements may include the following: • Sewer main extensions, modifications and replacements • Side sewer connections to City mains • Sewer Lift Stations 4.1 Easements and Rights-of-Way Permanent on-site easements for access, maintenance, and construction are required for all sanitary sewer extensions located outside of public Right-of-Way. Whenever an Easement or Right-of-Way is fenced, a gate shall be installed matching the width of the Easement and a City of Kent lock must be placed in XAseries" to facilitate access by the City. When easements are required, legal descriptions shall be prepared by a Professional Land Surveyor licensed by the State of Washington. A title report, dated within 30 days, for all properties to be encumbered by the easements shall accompany the description. When off-site and/or on-site easements for the extension of approved comprehensive sanitary sewer plans are required, these easements shall be approved and recorded by the City before any Civil Construction Permit is issued, unless the easements are being dedicated to the City as a part of the final recorded subdivision. Private improvements such as buildings, fences, garages, carports, retaining walls, utilities, signs, light standards, etc., are not allowed in public easements and rights- of-way. Where an encroachment occurs, the Developer shall remove and relocate the conflicting private improvement immediately upon direction from the Engineer and restore the area to a condition compatible for the intended use of the Easement by the City. 4.1.A Easement Requirements Easements shall be accessible for construction equipment normally used for the operation and maintenance of the facility. Cross slopes exceeding 5% will require a deviation approval of the Engineer. The minimum easement widths, centered on the utility system are as follows: 1. Sanitary Sewers 0'-5' deep: 15' wide 2. Sanitary Sewers 5'-9' deep: 25' wide 3. Sanitary Sewers over 9' deep - The formula for half of the width of the Easement shall be the sum of the total depth from the top of pipe to the surface, plus the pipe diameter, plus 3', rounded to the nearest even foot. 4-1 120 4. Special conditions or installation requirements may require greater easement widths as determined by the Engineer. 5. In easements with multiple utility systems, the Easement width shall be increased by the minimum separation distance between the lines. 6. In easements with multiple utility systems, the Easement width shall be increased by the minimum separation distance between the lines. 4.1.B Right-of-Way Where possible, utility system extensions shall be located within City right-of-way. Work inside adjacent Cities, King County and State Right- of-Way requires special permits from the appropriate agencies. City, King County and State right-of-way permits must be obtained by the Developer or the City if required by franchise prior to construction Plan Approval by the City. 4.2 Plan Approval and Permits The construction of sanitary sewer extensions within the City and approved franchise service areas requires the approval of the City of Kent, the State Department of Ecology (DOE), and KC/DNR-WTD. No construction shall be permitted until the Engineering Plans have been reviewed and approved by these agencies. Said construction is also subject to City permit and plan review fees (Contact the Permit Center for a current fee schedule). 4.3 Sanitary Sewer System Design Requirements 4.3.A General All sanitary sewer systems shall conform to the design requirements of the Criteria for Sewage Works Design issued by the DOE and the WSDOT Standard Specifications as shown in Section 1.6, References. All Work shall comply with the design requirements of King County/Department of Natural Resources-Waste Treatment Division (KC/DNR-WTD.) when connections are made to their system. 4.3.113 Comprehensive Sanitary Sewer Plan The City of Kent has developed a comprehensive sewer plan to allow the orderly and cost effective development of sewerage facilities to serve existing and future users of the Kent sewer system. The Comprehensive Sanitary Sewer Plan includes a map of proposed sewer extensions to service areas presently not served by the City. The plan shows the general location of interceptor and trunk sewers, intended to provide the framework of the collection system for the service area. All proposed sewer improvements and extensions shall be consistent with the Comprehensive Sanitary Sewer Plan. 4-2 121 4.3.0 Service Area Considerations All sewer extensions shall be designed for the ultimate development of the service area in accordance with current land use plans. The determination of the tributary area shall be based on the Comprehensive Sanitary Sewer Plan and detailed studies of the areas affected. The Engineer shall assist in the determination of the tributary area and must approve the service area plan prior to detailed design of the sewer system. New sewer systems shall be designed on the basis of per capita flows or other methods as approved by the City and DOE detailed design calculations and service area maps shall be required for the system design. Special considerations must be given to sanitary sewer extensions for industrial districts. The potential for pre-treatment requirements, excessive sewage flows, protection of new or existing manholes from corrosive discharge, special flow metering or sampling requirements must be considered in the industrial sewer collection system design. 4.3.113 Extent of Sanitary Sewer Improvements The sanitary sewers shall be extended to the limits of the respective property being served in accordance with the Comprehensive Sanitary Sewer Plan. The extension shall be of the size and Profile Grade necessary to be extended to other properties upstream in the future. In cases where the plan does not require future extension, the sewer system shall be extended as necessary to serve the affected property. 4.4 Design Standards 4.4.A Diameter The minimum diameter sanitary sewer main shall be 8". Larger diameters may be required to accommodate capacity or to minimize grades. 4.4.113 Velocity and slope All sanitary sewers shall be designed and constructed to provide a minimum velocity of 2' per second (fps) flowing full. The maximum non- restrained pipe allowable velocity shall be ten (10) fps. Where velocities are greater than 10 fps or Slopes greater than 20%, pipe anchors shall be required with a detailed drawing submitted to the City for approval by the Engineer. Velocities over 30 fps are to be avoided and may require odor control facilities to be installed by the Developer at the direction of the Engineer. The following are the minimum, acceptable slopes for sanitary sewers as permitted by DOE and the City: 4-3 122 Table 4.1 Sewer Size Inches Minimum Slope 4" 2.00% - Private Side Sewer 6" 1.00% - Private Side Sewer 8" 0.40% loll 0.28% 12" 0.22% 15" 0.15% 18" 0.12% 21" 0.10% *Based on Mannings "n" value of 0.013. 4.4.0 Alignment and Grade All sewers shall be designed and constructed with a straight alignment and continuous Profile Grade between manholes. 4.4.D Depth All sewer mains shall be buried deep enough to prevent freezing, breakage, and provide adequate depth to service the lowest fixtures on the properties served. The minimum cover for PVC sewer pipe (Minimum SDR 35) is 3' or Manufacturer's recommendation whichever is greater. 4.4.E Location All sanitary sewers shall be located at least 10' horizontally, on each side of the pipe, from the outside edge of an existing or proposed watermain. Any deviation from this requirement shall meet DOE requirements and will be allowed only upon approval from the Engineer. Sanitary sewer crossings under watermains shall be laid at such an elevation that the outside top of the sewer pipe is at least 18" below the outside bottom of the watermain. Where sanitary sewer mains have less than 10' of horizontal and 18" of vertical separation, the sanitary sewer main shall be constructed with a minimum of Class 50 ductile iron pipe. The ductile iron pipe shall be one continuous nominal 18' pipe length centered across the water line. 4.4.F Access Roads Access roads to all manholes are required for maintenance. Access and/or maintenance roads (where required) shall be 15' wide and shall accommodate turning movements for a BUS-40 Design Vehicle. Access and/or maintenance roads will require an approved all-weather surface, and shall be designed to support an HS-20 vehicle load. The Profile Grade 4-4 123 of an access road shall not exceed 15%. Access roads with grades exceeding 12% shall be paved. All access roads longer than 150 feet from the nearest face of curb or edge of pavement of the connecting Street shall have an approved turnaround per Standard Plan 6-18 through 6-21 or shall be looped to connect back to a public Street. Whenever an Easement or Right-of-Way is fenced, a gate shall be installed matching the width of the Easement and a City of Kent lock must be placed in "series". 4.4.G Garbage areas, enclosures and car washes Garbage areas and enclosures, and community car wash areas exceeding 200sf shall be covered and discharge to the sanitary sewer system, not the storm drain. 4.4.H. Casings Where a sewer line passes under or through a retaining wall or is attached to a bridge structure, the pipe shall be cased in steel pipe at least 4" larger than the largest outer diameter of the bell or joint of the sewer line. No pipe joints will be allowed within the casing, except on bridge structures or unless otherwise approved by the Engineer. The casing shall extend on either side of the wall a distance equal to the highest height of the retaining wall at the wall penetration, plus 4 . All voids within the casing shall be filled with blown sand except on bridge structures. Casing spacers shall be Cascade Waterworks Manufacturing Company stainless steel casing spacers or approved equal. The casing spacers shall be installed such that the watermain is centered and restrained within the casing and spaced such that a uniform Profile Grade will be maintained within the casing. 4.5 Sanitary Sewer Manholes 4.5.A Locations Sanitary sewer manholes are required at the following locations: 1. At the end of all sewer mains 8" and larger. When the main is to be extended in the future, the end of the line shall be a bell, plugged and marked with a 2" x 4" stake. Cleanouts are not acceptable in main line installations, except at the end of a dry or inactive sewer line which will be connected or extended in the future. 2. All changes in slope. 3. Changes in sewer main pipe diameter. 4. All connections to the main line 8" and larger. 5. Changes in sewer alignment. 6. Manholes shall be located at no more than 400' intervals. 4-5 124 4.5.113 Diameter The minimum diameter of sewer manholes shall be 48" for sewer pipes up to 18" in diameter. Larger diameter manholes will be required for special configurations and sewer pipe larger than 18". 4.5.0 Cones All standard City manholes shall have pre-cast eccentric cones except for special shallow manholes which may have concentric cones. All manholes shall be equipped with City approved drop rung type safety steps. Flat slabs shall not be used unless approved by the Engineer. See Standard Plan 4-1. 4.5.D Drop Connections Outside drop connections shall be avoided whenever possible. When no other alternative is feasible, an outside drop connection will be required at all locations where the entering sewer is 24" or more above the outfall invert elevation. Line connections to manholes or to stubs integral to a manhole shall be made with approved flexible joints. See Standard Plan 4-6. Inside drop connections are not allowed,_unless the diameter of the manhole is increased an equal amount to compensate for the inclusion of the drop inside the manhole. 4.5.E Channels The sanitary sewer manholes shall be fully channeled to conform to the inside diameter of the sewer line from invert to spring line, then the channel shall be vertical to the top of the pipe. The top edge of the channel shall have a radius of 1/2" to 3/4". The shelves shall slope at 2% to the top of the channel. All manhole section joints and pick holes shall be filled with grout and smooth finished outside and inside after installation. See Standard Plans 4-2 & 4-1. 4.5.F Downstream Invert Where feasible, a 0.1' drop from invert to invert across manholes is required. Where diameters change, the downstream invert shall be lowered so that the elevation of pipe crowns match. The maximum drop from invert to invert across manholes shall be 1'. 4.5.G Soil Pressure Care must be taken to insure that pressures exerted on the soils beneath the manholes and the adjacent mains are approximately uniform. Unequal soil pressures may result in uneven settlement at manholes. A spread foundation or other measures may be required to reduce the unit load imposed by the manhole. All manholes shall be provided with KOR- IN-SEAL type flex joints or sand collars meeting ASTM D-303H-78 SDR35 4-6 125 specifications or other materials as approved by the Engineer to allow slight differential movement. 4.5.H Street Grade No less than 4" or greater than 16" shall be provided between the top of the cone and the underside of the manhole frame for adjustment to street Profile Grade or ground surface. Final elevation of the frame and cover shall conform to the restored street or ground surface. All joints in the brick or ring adjustment shall be filled with grout and the castings shall be seated in grout placed on the ring or brick. A 3/8" mortar lining shall be installed inside and outside of the adjustment section to form a smooth watertight finish. 4.5.I Locking Rings All Manholes shall have locking rings and covers with City of Kent logo on lid in public areas and with no City of Kent logo on lid in private sewer Manholes. See Standard Plans 4-3 & 4-4. 4.5.3 Corrosion Protection Where the possibility of odors, gasses or corrosive discharges could be present in the sewer line, or where required by the Engineer, corrosion protection of the inside of the manhole may be required. Based on the material to be discharged, the Engineer will determine the particular type of corrosion protection in the manhole. Sealed manhole covers shall be required for this type of installation. Depending on the size of the sewer line, and in the event that odor is a concern, as determined by the Engineer, an odor control system may be required to be designed and constructed for the sewer system affected. 4.6 Private Side Sewer Systems Sanitary sewer service lines that extend from the mainline are considered private side sewers. Side sewers are to be constructed and maintained by the property owner in accordance with the KCC 7.04. 4.6.A Sewer Permit Prior to construction, replacement, repair, connections or additions to a side sewer, the Developer or authorized agent must obtain a Sewer Permit from the City. A separate Sewer Permit is required for each Lot. Accessory structures such as accessory dwelling units and portables may be served by the sewer service to the primary building as long as that service was approved and installed per the requirements for side sewer connections. The City shall review the application, require or make changes if needed, approve the side sewer plan, and assess the Developer for applicable latecomer charges, charge in lieu of assessments, traffic mitigation fees, permit fees, tapping charges, street restoration bonds and 4-7 126 other charges as required. Contact the Permit Center for a current application and fee schedule. 4.6.B Side Sewer Design Standards 1. The minimum diameter of a side sewer shall be no less than 6" within the Right-of-Way and then may be reduced to no less than 4" for services to a single-family residence, from the Right-of-Way or easement line to the building. All side sewers 8" in diameter shall be designed in accordance with the requirements of Sections 4.3 thru 4.5 and 4.7 thru 4.8. 2. All side sewers shall be laid in a straight alignment and have cleanouts located on the straight run after each total 900 change of horizontal direction and each vertical change in slope, and at the termination of the sewer within 5' outside of the building. The maximum length of 6" side sewer between manholes is 400 feet with clean-outs required every 100' minimum. 3. The maximum deflection for 4" and 6" diameter pipe permissible at any one fitting shall not exceed 450 (one-eighth (1/8) bend) unless straight pipe of not less than 2.5' feet in length is installed between adjacent fittings, or unless one such fitting is a wye fitting with a clean-out provided on the straight leg. 4. Side sewers, where possible, shall not be less than thirty inches (30") from any building, have 6' cover at the property line, and a minimum of 2' of cover on private property. 5. Joints shall be tight and waterproof. All side sewers shall be tested full length in compliance with the City standard air or hydrostatic test and in the presence of the Inspector. 6. Sanitary sewer and domestic water lines shall not be laid in the same trench. Parallel water and sewer lines shall be laid at least 10' apart horizontally. Wherever it is necessary for sewer and water lines to cross each other, the crossing should be at an angle of approximately 900 and the top of the sewer pipe shall be located at least 18" below the bottom of the water line or be constructed of Class 50 ductile iron pipe with water tight joints. The ductile iron pipe shall be one continuous length of pipe 18' long and placed symmetrically across the water line. 7. Side sewers installed in filled or unstable ground shall be constructed of Class 50 ductile iron pipe, except that PVC pipe may be accepted if laid on a suitable concrete bed or cradle as approved by the Engineer. 8. Installation of sewer pipe shall be accomplished to line and Profile Grade only after the trench has been dewatered and the foundation and/or bedding have been prepared. Mud, silt, and gravel and other foreign materials shall be kept out of the pipe and off the jointing surfaces. All pipe laid shall be retained in position so as to maintain alignment and joint closure until sufficient Backfill has been completed. 4-8 127 9. The sewer pipe shall be laid up grade from the point of connection on the existing sewer or from a designated starting point. The sewer pipe shall be installed with the bell upgrade unless otherwise approved by the Engineer. 10. Cleanouts are required at the right-of-way or easement line. See Standard Plans 4-7 & 4-8. 11. All cleanouts within 5' of the Right-of-Way line shall be brought up to Grade. Clean outs within private property in grass or landscaped areas may be buried a maximum of one foot. 12. Cleanouts installed under concrete, asphalt or other permanent surfaces shall be extended to finish grade with the same size and type of pipe and fittings as required for the side sewer. A cast iron ring and cover shall be installed to provide access and protection from traffic. See Standard Plan 4-7. 13. All side sewers shall function on a gravity basis, unless a specific deviation is approved by the Engineer. 14. In new Projects or subdivisions where street improvements are to be made, each service shall be marked by a "SS" in the curb where it crosses perpendicular to the curb. The marking shall be done at the time the curb is installed and shall be as-built by stationing. Lettering shall be 3" high and a minimum 1/4" deep. 15. Existing building side sewers may be used in connection with new side sewers only when they are found, on examination and test performed by the property owner and reviewed by Engineer, to meet all of the applicable requirements of these Standards. 4.6.0 Connections Each legally defined property shall be serviced by a separate side sewer stub connected to the City sewer main. For multi-tenant sites such as multi-family or commercial uses, each building shall have a separate minimum 6" side sewer. The maximum number of individuals permitted on a 6" diameter sewer shall be 30 persons. In general, up to 10 units in a multi-family dwelling may be serviced by a single 6" diameter side sewer. 4.6.D Grinder Pumps Where gravity flow for side sewer is not possible, a privately owned and maintained grinder pump system to service individual structures requires specific deviation by the Engineer. The pumping system shall be designed in accordance with Section C1-10.1 of the Washington Department of Ecology's "Criteria for Sewage Works Design". These assemblies shall be located adjacent to the structure, and shall be equipped with both high level and pump failure alarms. The alarms shall be both audio and visual, and be on a separate circuit from the pump. 4-9 128 Residential systems will be a package-type system Hydromatic TL-Pro System using a HPGR 200 Submersible Sewage Grinder Pump or approved equal. Each pressure system shall have an individual connection to the City sewer. Lift systems for commercial and multi-family structures require special maintenance agreements and specific deviation by the Engineer. Submittal is required for each Permit prior to approval. Solid handling waste pumps are not allowed. Refer to Section 4.8.0 for air testing force main systems. See Standard Plan 4-10. 4.6.E Connection to City Sewer System All lots adjacent to a new City sewer main or extended City sewer main shall be serviced with a 6" side sewer stubout extended to the property line. The location of sewer stubouts shall be marked with a 2" x 4" post and tracer wire. The Development shall be designed to utilize the stubout as installed. See Standard Plans 4-8 & 4-9. The City maintains records concerning the location and approximate depth of recent side sewer stubouts. These records are for informational purposes only and it shall be the Developer's responsibility to verify the location and depth of existing services. In cases where a stubout has not yet been installed, the Developer shall connect directly to the City main in accordance with the Standard Plan 4- 9. The Developer shall assume all cost for said connection, including, but not limited to, street repairs, tapping charges, permits, all associated system charges as appropriate, including but not limited to Systems Development Charges, King County-Capacity Charges, etc. The actual tap to the main shall be accomplished by the City of Kent Utilities Section after the Developer has prepared the trench and provided an access to the tapping area for a truck and crew. OSHA trench safety requirements shall apply for shoring. (Contact the Permit Center for a current fee schedule). 4.6.F Waste Discharge Approval Storm water, surface water, ground water, cooling water and industrial processes that have been polluted as determined by the Engineer and KC/DNR-WTD are required to be discharged to the City sewer main through an approved pretreatment system and metering method. Pretreatment requirements of the discharge shall be determined and approved by KC/DNR-WTD. Metering, billing and authorization to discharge shall be determined and approved by the Engineer. A Sewer Permit shall be required from the City and can be obtained as outlined in Section 4.6.ASewer Permit. The City will not issue a Sewer Permit without prior discharge approval from KC/DNR-WTD. Metering methods shall be determined and approved by the Engineer on a case-by-case basis. See Section 3.14 for the Sewer Rate Meter applications. 4-10 129 The type and size of grease interceptor(s) when required shall be approved by the Engineer. Combined grease interceptors shall not be allowed. Each business requiring a grease interceptor shall have its own grease interceptor, unless otherwise directed by the Engineer. Annual Maintenance Reports shall be provided on all Grease Interceptors to Public Works Operations located at 5821 S 240th Street, Kent, WA 98032. See Standard Plan 4-11. 4.6.G Inspection Before Trenches are Filled No trench shall be filled or any connecting sewer covered, until the Work from the point where the side sewer connects with the public sewer or other outlet to the point where it connects with the plumbing of the building or premises has been inspected and approved by the Engineer. 4.6.H Excavation in Streets to be Protected All Excavations made within the limits of any Right-of-Way or other public place shall be protected by fencing covering or other means approved by the Inspector at all times. 4.7 Sanitary Sewer System Materials 4.7.A Standards All materials used for construction of City sewer mains, side sewers, and Appurtenances, shall be new and undamaged. All materials to be used shall be subject to inspection by the Engineer prior to use. The Developer shall provide the Engineer with shop drawings and Certificate of Materials, as requested. All materials and equipment shall be installed in accordance with the manufacturer's recommended installation procedures and these Standards. 4.7.B Gravity Sewer Pipe Unless otherwise approved, all sewer pipes shall be Solid Wall PVC (Polyvinyl Chloride) SDR 35, conforming to ASTM 3034 or 3035 specifications or ductile iron pipe, Class 50 for gravity applications or Class 52 for force mains. The sewer pipe shall be clearly marked with the type, class, thickness, and manufacturer. The lettering shall be legible and printed at the factory. 4.7.0 Fittings All sewer pipe fittings shall be of the same material as the pipe. The size of the cleanout shall be the same size as the sewer pipe. All fittings shall have rubber gaskets with manufactured pipe stops, integrally formed. Where dissimilar pipe materials can not be avoided Romac couplings shall be utilized. 4-11 130 4.7.D Manholes and Covers Sanitary sewer manholes shall be pre-cast concrete units constructed in accordance with the WSDOT Standard Specifications.

Whenever an Easement or Right-of- Way is fenced, a gate shall be installed matching the width of the Easement and a City of Kent lock must be placed in "series". All access roads longer than 150 feet from the nearest face of curb or edge of pavement of the connecting Street shall have an approved turnaround per Standard Plans 6-18 through 6-21 or shall be looped to connect back to a public Street. 5.3.0 Casings: Where a storm water line passes under or through a retaining wall or is attached to a bridge structure, the pipe shall be cased in steel pipe at least 4" larger than the largest outer diameter of the bell or joint of the storm water line. No pipe joints will be allowed within the casing, except on bridge structures or unless otherwise approved by the Engineer. The casing shall extend on either side of the wall a distance equal to the highest height of the retaining wall at the wall penetration, plus 4'. All voids within the casing shall be filled with blown sand except on bridge structures. Casing spacers shall be Cascade Waterworks Manufacturing Company stainless steel casing spacers or approved equal. The casing spacers shall be installed such that the storm water line is centered and restrained within the casing and spaced such that a uniform Profile Grade will be maintained within the casing. 5.4 Catch Basin Locations and Junctions 5.4.A Catch Basins Catch basins, rather than inlets, shall be used to collect storm water from street surfaces, unless approved by the Engineer. See Standard Plans 5-1 & 5-2. 5.4.B Connections to Pipe Systems Connections to pipe systems may be made without placing a catch basin or manhole on the mainline in accordance with Standard Plan 5-18. All other connections shall be made at catch basins or manholes. 5-2 151 5.4.0 Manholes in Lieu of Catch Basins Manholes may be used in lieu of catch basins if they do not collect surface water. Manholes must be used if invert elevations are different by more than 18". See Standard Plan 4-1. 5.4.13 Control Structure Placement A control structure shall be placed in a manhole downstream of detention systems utilizing pumps. 5.4.E Roof and Yard Drains Roof and yard drains, or other concentrated flow from adjacent property, shall not discharge over the surface of streets, sidewalks, pathways, or shoulders. The location of at least two points of all catch basins shall be surveyed to ensure that the catch basin, frame and grate will properly align with finished curb, horizontally and vertically. 5.5 Frames, Grates, and Covers 5.5.A Metal Castings for Drainage Structures Metal castings for drainage structures shall not be dipped, painted, welded, plugged or repaired. 5.5.B Porosity in Metal Castings for Drainage Structures Porosity in metal castings for drainage structures shall be considered a workmanship defect subject to rejection by the inspector. 5.5.0 Casting for Manhole Rings Castings for manhole rings shall be gray-iron conforming to the requirements of AASHTO M 105, Grade 3013. Covers shall be ductile iron conforming to ASTM A 536, Grade 80-55-06. Manhole rings and covers shall meet the strength requirements of Federal Specification RR-F-621 E. All mating surfaces shall be machine finished to ensure a non-rocking fit. 5.5.D Manhole Rings and Covers Identification All manhole rings and covers shall be identified as specified in Section 9-05.15 of the WSDOT Standard Specifications. See Standard Plan 5-10. 5.5.E Metal Frame Castings for Catch Basins and Inlets 1. Castings for metal frames for catch basins and inlets shall be cast steel, gray iron, or ductile iron as specified in Sections 9-06.8, 9- 06.9, or 9-06.14 of the WSDOT Standard Specifications. 5-3 152 2. Castings for metal frames for catch basins, inlets, grates and solid metal covers shall meet the strength requirements of Federal Specification RR-F-621 E. 5.5.F Metal Grates & Covers for Catch Basins and Inlets Castings for grates and solid metal covers for catch basins and inlets shall be cast steel or ductile iron as specified in Sections 9- 06.8 or 9-06.14 of the WSDOT Standard Specifications. The foundry name and material designation shall be embossed on the top of the grate. The material shall be identified as "CS" for cast steel, and "DUC" or "DI" for ductile iron and shall be located near the manufacturer's name. See Standard Plans 5-9 through 5-4. 5.5.G Grate and Cover Seating Grates and covers shall be seated properly to prevent rocking, including the replacement of existing covers with solid metal covers. 5.5.H Vaned Grates Unless otherwise specified, vaned grates shall be used with standard frame in the Traveled Way, gutter, or shoulder. Vaned grates shall not be located within crosswalks. See Standard Plans 5-4 through 5-6. 5.5.I Rolled Curbs Use rolled curb frame and grates along rolled curbs. See Standard Plan 5-7. 5.5.3 Runoff Collection in Catch Basins New catch basins that do not collect runoff shall use solid locking covers. Existing catch basins, which no longer collect runoff, shall have their frame and grates replaced with new frames and solid covers. See Standard Plan 5-9. 5.5.K Locking Drain Covers and Grates All storm drain covers and grates shall be locking. All control structures storm drain covers shall be locking regardless of their location. 5.6 Television Inspection All new storm drain extensions will be TV camera inspected by the City prior to acceptance. Prior to TV camera inspection: 1. Storm drain lines and catch basins must be cleaned 2. All construction must be completed and approved by the Inspector. 5-4 153 The casting and top grade rings do not have to be mudded in until after the Finished Grade is established. The Developer shall bear all costs for correction of deficiencies found during TV inspection, including all costs for subsequent TV inspections to verify the correction of deficiencies. The Developer shall schedule TV Inspection no less than 5 working days prior to being ready. If the system is not ready, the Developer shall notify the City no later than 24 hours prior to the scheduled time. If the Developer fails to notify the City that they are not ready and the TV Inspection crew shows up at the Site, the Developer will be responsible for all costs of additional TV inspections to verify the system. All Costs for re-inspections including the Inspector's time to come back due to "not being ready" will be the responsibility of the Developer. Costs shall include labor at overtime rates, overhead, equipment, material and any other associated charges. The costs shall be based on the latest cost schedule prepared and approved annually by the Engineer. Sags in storm drain lines indentified during the TV inspection greater than 0.5" shall be repaired by the contractor by removal and re-laying of the pipe. Repaired sections of pipe shall be TV inspected for verification prior to Final Inspection at the cost of the Developer as described above. 5.7 Erosion Control All Projects shall provide Erosion control in accordance with the KSWDM. The State Department of Ecology requires coverage under the NPDES Construction Stormwater General Permit when the disturbed area for the Project exceeds one (1) acre. The NPDES Permit requires that a stormwater pollution prevention plan (SWPPP) be developed for all Projects covered. A Certified Erosion and Sediment Control Lead will be required by DOE to be onsite during construction. See the Department of Ecology website at: http://www.ecy.wa.gov/programs/wq/stormwater/construction See the Kent Surface Water Design Manual (KSWDM), King County Surface Water Design Manual (KCSWDM) for allowable erosion control best management practices. See Standard Plans 5-27, 5-30 & 5-31 for additional information. 5.8 Low Impact Development Technologies The City of Kent encourages the use of Low impact Development (LID) technologies. Low impact Development is a stormwater management and land Development strategy applied at the parcel and subdivision scale that emphasizes conservation and use of existing natural site features integrated with engineered small scale hydrologic controls to more closely mimic pre- development functions. The goal of LID is to prevent measurable harm to 5-5 154 streams, lakes, wetlands, and other natural aquatic systems from residential, commercial, or industrial Development sites. LID technologies include stormwater best management practices designed to reduce runoff from Development using infiltration, evapotranspiration, or stormwater reuse. Examples of LID technologies include trees, porous pavement, bio-retention swales, infiltration systems, dry wells, cisterns, and rain gardens. Examples of these technologies are provided in the 2005 King County Surface Water Design Manual. 5-6 155 5.9 Storm Drain System Standard Plans 5-1 Catch Basin Tvpe I 5-2 Catch Basin Tvpe II 5-3 Misc.

All portions of the Traveled Way, curbs, gutters, sidewalks, medians, drainage facilities, street lighting, traffic signals, roundabouts, traffic circles, traffic signage and other required improvements shall be located within said Right-of-Way. Easements for the purpose of construction, access, maintenance, sight distance preservation, street slopes, street lighting, or for utility and storm drain system installations may be required in conjunction with new street and street improvements. A 10' utility and street lighting Easement shall be provided by all private development Projects adjacent to all Public Streets except in the Downtown Overlay. Permanent on-site easements for access, maintenance, and construction are required for all public and private street systems serving more than one property located outside of public Right-of-Way. When easements are required, legal descriptions shall be submitted prepared and stamped by a Professional Land Surveyor. A title report, dated within the last 30 days, covering the properties to be encumbered by the easements, shall accompany said description. When off-site and/or on-site easements for the extension of public or private street, water, sanitary sewer, storm drainage or other utility systems are required, these shall be approved and recorded prior to approval of the Engineering Plans. The same conditions shall also apply regarding legal descriptions and title reports. 6.2 Street Types and Geometrics General design objectives and purpose by functional classification for City streets are listed in the Kent Transportation Master Plan. Based upon these classifications, the criteria for Right-of-Wax, street width and other Geometrics are established by the City. The Kent Transportation Master Plan defines the following streets: • Principal Arterial 7 - Lanes, See Standard Plan 6-2. • Principal Arterial 5 - Lanes & Minor Arterial, See Standard Plan 6-3. • Collector Arterials - Industrial Collector Arterial, See Standard Plan 6-4. • Collector Arterials - Residential Collector Arterial, See Standard Plan 6-5. • Collector Arterials - Residential Collector, See Standard Plan 6-6. 6-1 194 • Local Access Streets - Industrial/Commercial, See Standard Plan 6-7 • Local Access Streets - Residential, See Standard Plans 6-11 through 13. Local Streets can be comprised of Industrial/ Commercial Streets, and Residential Streets. These streets are based on the land use zoning adjacent to the Street. There are also Alleys and Private Streets. Where appropriate and feasible, Right-of-Ways should be increased to accommodate the use of low-impact Development and materials to handle storm water, including landscaped medians facilitating natural storm water function and bio-filtration areas (rain gardens and swales). 6.2.A Arterial Streets Arterials generally support higher traffic volumes, much of which is generated outside of the immediate area or what is termed "through traffic". Arterials support the travel of cars and trucks and other modes, including public transit, cycling and walking. Existing Driveways may be required to be eliminated to comply with the access management requirements of these Standards. Driveway access to Minor Arterial and Collector Arterial streets will be managed to retain the traffic bearing capacity of the roadway while allowing access to parcels not served by streets of a lower classification. Existing Driveways may be required to be eliminated if adequate access can be provided by streets of a lower classification. 6.2.B Local Streets These streets are designed for local traffic usage. They are typically the streets in front of residential property and some commercial and retail uses. Two subcategories of Local Street classifications exist based upon the type of adjacent land-use. The sub-categories, and their functions, are: 1. Industrial/Commercial Street - These streets are designed to provide direct access from the abutting industrial or commercial land uses to the collector arterial classified streets. Access to these streets is typically not restricted for reasons of safety except at or near Intersections. On-street parking is not permitted unless otherwise approved by the Engineer. 2. Residential Street - These streets are designed to provide direct access to abutting land uses, from collector streets in a safe and efficient manner. The design parameters of these streets, i.e., intersection spacing, horizontal curves criteria, and right-of-way assignment at Intersections, will be used to minimize vehicle operating speeds and non-locally generated ("cut-through") traffic. On-street parking will generally not be restricted, except at those locations necessary for public safety. A high emphasis will be placed on safely 6-2 195 accommodating non-motorized and pedestrian traffic in the design of these streets. Private Streets fall within the residential street classification. However, the geometric requirements for Private Streets are different and can be found within Section 6.2.D Private Streets. 6.2.0 Alleys The horizontal and vertical geometric design criteria for residential streets shall be used to design Alleys. Alleys must be designed within the following parameters: 1. An Alley may serve a maximum of 30 dwelling units; have a maximum length of 400'; and have no Dead Ends or Cul-de-Sacs. 2. The Right-of-Way or Tract width shall be sufficient to construct the Alley and related Grading. The minimum Tract width shall be 20' with a pavement surface width of 20' based on a 5' structure setback. For differing structure setback requirements, the Alley surfacing width may be reduced to 18'minimum if designed to provide for safe turning access to properties. 3. Alleys shall be paved surface and have an inverted crown to control surface runoff. 4. Alleys shall connect to the Public Street system using a Private Street Approach. See Standard Plan 6-46. 5. Alleys shall not intersect other Alleys or Half Streets. 6. Alleys shall provide secondary access only to a property. 6.2.D Private Streets Any Street serving, or proposed to serve nine (9) or fewer single-family dwelling units, as determined by the Engineer, and certain streets within a Planned Unit Development (PUD) may be considered Private Streets. When streets directly adjoin other lots, those lots are counted when determining the number of lots served, including any potential new lots created through Redevelopment consistent with the zoning designation. Private Streets may be approved only when they are: 1. Permanently established by tract providing legal access to each affected Lot, dwelling unit, or business; and sufficient to accommodate required improvements, to include provision for future use by adjacent property owners when applicable; and 2. Built to the Standards, as set forth herein, and 3. Accessible at all times for emergency and public service vehicle use; and 4. Not part of, or obstructing the present or future public neighborhood circulation plan developed in processes such as the City of Kent's 6-3 196 Comprehensive Plan, Transportation Master Plan, or Capital Improvement Program; and 5. Not going to result in land locking present or future parcels; and 6. Not needed as Public Streets to meet the street spacing requirement or to provide access to surrounding parcels for future Development; and 7. Designed to serve a potential maximum of 9 single-family dwelling units for the entire length of the Private Street system to the nearest publicly maintained Street, when physical barriers, zoning or other legal constraints are considered; and 8. Maintained by a capable and legally responsible homeowners' association or other legal entity made up of all benefited property owners; and 9. Clearly described on the face of the plat, short plat, binding site plan, site development Permit or other Development authorization and clearly signed as a private Street, for the maintenance of which the City is not responsible. 10. Private Streets shall connect to the Public Street system using a Private Street Approach. See Standard Plan 6-46. Private Streets serving more than 9 lots in a PUD may use an intersection design utilizing curb returns. 11. Parking is allowed on one side only. Parking is also prohibited on both sides within 60 feet of the intersection with the connecting street. This requirement may be reduced by the Engineer based on vehicle maneuvering diagrams provided by the Developer that shows a parking configuration that allows a Bus-40 vehicle to access the private street, if required. 12. The City will not accept existing Private Streets as Public Streets until they are constructed or reconstructed in conformance with current Kent City Code and these Standards. 13. Best Management Practices (BMP'S) shall be used when maintaining Private Streets. 14. Whenever a private Street extends more than 150 feet from the nearest face of curb or edge of pavement of the connecting Street, a temporary Cul-de-Sac or Hammerhead Turnaround per Standard Plans 6-18, 6-21 & 6-22 shall be constructed. 6.2.E Public Half Streets 1. Half streets may be permitted as an interim facility when: a. Such Street shall not serve as primary access to more than 30 dwelling units; and b. Such alignment is consistent with or will establish a reasonable circulation pattern; and 6-4 197 c. There is reasonable assurance of obtaining the prescribed additional Right-of-Way through future Development from the adjacent property with topography suitable for completion of a full-section street. 2. A Half Street shall meet the following requirements: a. Right-of-way width of the Half Street shall be a minimum width of 32' and sufficient to construct the Street and related Grading; and b. The Half Street shall have a crown section consistent with locating the centerline of the ultimate street section, as close as possible to the property line; and c. Traveled way shall be surfaced the same as the designated street type to a width no less than 20', combined curb and gutter, sidewalk and planter strip shall be constructed per Standard Plan 6-13; and d. Property line edge of Street shall be finished with temporary curbing, shoulders, ditches, and/or side slopes in order to assure proper drainage, bank stability, and traffic safety; and e. Half streets shall not intersect other Half Streets or exceed these requirements unless otherwise approved by the Engineer. f. Whenever a Half Street extends more than 150 feet from the nearest face of curb or edge of pavement of the connecting Street, a temporary Cul-de-Sac or turnaround per Standard Plans 6-18, 6-21 & 6-22 shall be constructed. 3. When a Half Street is eventually turned to a whole Street, the completing builder shall reconstruct the original Half Street as necessary to produce a proper full-width crowned Street of a designated section per these Standards. 4. Obtaining any Right-of-Way or easements to accomplish the above shall be the responsibility of the Developer. 6.2.F Cull-de-sacs, Islands, and Hammerheads The following design parameters shall apply to Cul-de-Sacs, islands, and Hammerheads: 1. Cul-de-sacs: Whenever a dead-end Street extends more than 150 feet from the nearest face of curb or edge of pavement of the connecting Street, a widened "bulb" shall be constructed as follows: a. The minimum right-of-way radius across bulb section is 51.50' in a permanent or temporary Cul-de-Sac. Right-of-way may be reduced, provided utilities and necessary drainage are accommodated on permanent easements within the Development, upon approval by the Engineer. b. The minimum radius of surfacing across bulb: 45' to the face of curb. See Standard Plan 6-18. 6-5 198 c. Sidewalks shall be constructed around the Cul-de-Sac. Planter strips are not required. d. Rolled curbs are allowed in Cul-de-Sacs. e. A permanent Cul-de-Sac shall not be longer than 600', measured from center of the intersecting Street, along the centerline of the roadway to the center of the Cul-de-Sac bulb. The Engineer will consider deviations to this requirement on the basis of pertinent traffic planning factors such as topography, sensitive areas and existing development. f. If a public Street temporarily terminates at a property boundary, serves or will serve more than nine lots, or is longer than 150 feet from the nearest face of curb or edge of pavement of the connecting Street, a temporary Cul-de-Sac bulb shall be constructed near the Development boundary. The paved bulb shall be 90' in diameter with sidewalks terminated as shown on Standard Plan 6-22. In lieu of the temporary Cul-de-Sac, a temporary Hammerhead turnaround may be provided as approved by the Engineer. g. Removal of the temporary Cul-de-Sac or Hammerhead turnaround and construction of the extension of the sidewalk shall be the responsibility of the Developer who extends the Street. See Standard Plan 6-22. h. The maximum cross slope in a bulb shall not exceed 6% in any direction. i. Partial bulbs or Eyebrows shall have a minimum paved radius and an island configuration, and the island shall be offset 4' from edge of Street. See Standard Plan 6-19. j. When a commercial access changes from a public to private designation, a public Cul-de-Sac shall be required, regardless of whether another fire access turnaround is provided elsewhere. 2. Cul-de-sac Island: A Cul-de-Sac island is an optional feature for any Cul-de-Sac when the bulb paved diameter is 90' or less; but it is mandatory when the bulb paved diameter exceeds 90'. If provided, the island shall have cement concrete vertical curb and gutter. Maximum island diameter shall be 15' and there shall be at least a 30' wide paved Traveled Way around the circumference and no parking will be allowed. An island shall be landscaped per Section 6.13 Landscape Requirements on Public Right-of-Way. The landscaping must be maintained by the homeowners association or other responsible entity or parties including all benefited property owners. See Standard Plan 6-19. 3. Hammerheads: A Hammerhead may be used to satisfy the turnaround requirements where a private Street serves or will serve 9 or fewer lots. The maximum Profile Grade of any leg of the 6-6 199 Hammerhead turnaround shall be 6%. Parking and Driveways shall not be allowed within the Hammerhead. See Standard Plan 6-21. 6.3 Street Improvements The City of Kent has developed a Transportation Master Plan, indicating existing and proposed streets and their functional classifications. It shall be the responsibility of the Engineer to identify specific conditions for street improvements and/or right-of-way reservation required as a condition of development. All street improvements shall be consistent with the adopted Comprehensive Plan, City of Kent Subdivision Code and other applicable Kent City Codes. In accordance with KCC 6.02, "Required Public Improvements", the Engineer is authorized to require the construction of off-site street and drainage improvements as a condition of issuing a Building Permit with an "improvements valuation" of $50,000 or 25% of the assessed value of the property and existing improvements. An appraisal may be used at the discretion and cost of the Developer. As required by these Standards or as a part of the SEPA review process, the required improvements and potential impacts of a proposed Project shall be identified. The Developer shall be required to construct the improvements. In lieu of construction and at the discretion of the Engineer, the mitigation of these impacts may satisfied through the execution of an environmental mitigation agreement in which the Developer and his/her successors, agree to participate in the cost of construction of future off-site street and utility system improvements. If the future improvements are proposed to be funded by a Local Improvement District (LID) formed by the City in connection with a project identified in the City's Capital Improvement Plan, the Developer may be required to pay a fee in lieu construction based on the Engineer's Cost Estimate Form or execute a No-Protest LID Covenant with the City. 6.3.A Minimum Public Street Improvements When Public Street improvements are required as a condition of a land use approval process, and an abutting public Street is not to current standards or is otherwise not adequate, the Developer is responsible for constructing the following minimum Public Street improvements along their entire property frontage on all Public Streets: 1. A half-street improvement shall be provided that is equal to one-half of the final design pavement width or a minimum of 20', as measured from the centerline of Right-of-Way, or from the approved centerline as determined by the Engineer, to the face of the new cement concrete curb. 2. The street improvement for the frontage along the Development shall include combined curbs and gutters, planting strips, street trees and landscaping, and cement concrete sidewalks depending on the street classification and the bike route classification. See Section 6.5, Driveways, Sidewalks and Non-Motorized Lanes or Trails, for additional information on sidewalks and Bike Lane requirements. 6-7 200 3. The street improvement will require an approved street lighting plan and an installed street lighting system meeting the requirements of these Standards. See Section 6.14, Street Illumination System, for addition information on street lighting design. 4. The total combined pavement width shall be shown to have a design/remaining service life of at least 20-years, in accordance with the AASHTO Guide for the Design of Pavement Sections Part I and Part II. 5. The Public Street improvements shall also include: street channelization street markings; traffic signs; a stormwater drainage conveyance, detention, and treatment system; traffic signals when specified; utilities and other street-related Appurtenances. 6. Depending upon the condition of the adjacent pedestrian system and the nature of the Development, the Developer may also be required to install specific on-site and off-site pedestrian sidewalks, pathways, or shared pedestrian and bicycle facilities. All subdivisions are required to provide for neighborhood connectivity via Street connections, pedestrian connections, bicycle facility connections, or some combination of these connecting facilities. At a minimum, the Developer is required to provide full improvements on their property, and tapers, merges or connections to existing improvements beyond the Project property boundaries. 7. All street improvements shall include provisions for street trees. The species of these street trees shall be selected from the list of approved street trees as shown in Appendix A and placed as shown in Standard Plans 6-54 & 6-55. 8. Monument Installation: Permanent concrete control monuments are required to be installed at controlling corners of all subdivisions and on new or re-aligned Public Streets. All Projects shall include the placement of centerline and intersection monuments. See Standard Plan 6-72. 9. Prior to the recording of any short plat or subdivision, all surveying and the setting of all lot corners and monuments shall be complete. 10. Where utility system construction for the proposed Development extends beyond the Half Street improvements, a full width overlay of the Street may be required by the Engineer. 6.4 Street Design Standards 6.4.A Street Design Summary The Street Design Standards Table 6.6.7 summarizes the minimum design standards for the various functional classifications of streets in the City of Kent. 6-8 201 6.4.B Downtown Overlay District The Downtown Overlay District revises and adds additional criteria for the streets within the downtown area of Kent. This area is bounded by State Route 167 to the west, Cloudy Street to the North, Kennebeck, Clark, Jason, Titus and Central Avenues to the east and Willis Street to the South. See KCC 15.09.046, Downtown Design Review. Street cross-sections within the overlay vary from the typical street cross sections.

See Standard Plan 6-56. 6. Street Lights: Street lights shall consist of Gullwing and Lumec Zenith Series luminaire fixtures for the street and pedestrian lighting respectively except on SR 516 (Willis Street) between SR 167 and Central Avenue where cobra head fixtures are allowed. No cobra head or King 118 luminaires will be allowed anywhere else within the Downtown Overlay unless otherwise approved by the Engineer. See Section 6.14 for street lighting requirements. 6.4.D Access Management Standard The City manages access through the use of medians, Auxiliary Lanes, Driveway location and design, Driveway separation, corner clearance, joint and cross access agreements, and alternative access from lowest classification Street. Unless otherwise approved by the Engineer, each vehicle shall be deemed to have a length of 25' for the purpose of calculating minimum storage lengths. 6-10 203 1. General Access Provisions: In general, all properties abutting Public Streets are permitted reasonable access to the Public Street system. Driveways directly giving access onto arterials may be denied if alternate access to another Arterial Street is available. On properties with multiple public Street frontages, the City will restrict vehicular access solely to the public Street having the lower Street classification, and/or to the safest access location. Retail, commercial or industrial Driveways shall be prohibited from access to residential streets. Coordinated access (via cross access, joint or reciprocal access agreements recorded with the County Auditor's office) with adjacent properties may be required of the developer, where Driveways are located on arterials or Driveway separation and corner clearances can not be achieved. The design of Driveways onto Principal and Minor Arterials may be required to restrict turning movements from or onto the Arterial Street, and may be required to be designed on a case-by-case basis. Factors to be considered in the design of turn-restrictive Driveway geometrics will include, but are not limited to the following: • Design vehicle • Vehicular sight lines, See Standard Plan 6-52 • Pedestrian sight lines, See Standard Plan 6-53 • Pedestrian oriented development • Driveway traffic volumes • Public Street traffic volumes and speeds • Public Street widths and Channelization • Driveway proximity to Intersections, and to other Driveways. The Engineer may require any combination of these factors to be considered in the design of the Driveway. 6-11 204 2. Access Type and Minimum Distance Allowed. Table 6.1 below shows the minimum Driveway separation and Intersection corner clearance based on street functional classification. TABLE 6.1 Access Separation Requirements Roadway Classification Principal Minor Collector Residential Indust/ Access type Residential Arterial Arterial Arterial Collector Comm. Minimum Driveway to Driveway Separation, 300' 200' 200' 50' 100, 10,3 measured closed edge to closest edge of driveway 2 Minimum Corner Clearance Standards, measured from the nearest edge of the driveway 300' 200' 100, 100, 50, 20' to the point of curvature on the curb return of the intersecting street 1 Residential Driveways shall be a minimum of 5' from the nearest edge to the property line. 2 For parcels adjacent to a traffic signal, 300' shall be used unless a traffic study successfully demonstrates that the Intersection area of influence is less than 300'. 3 On a case-by-case basis, Cul-de-Sacs may be allowed less than a 10'separation. 3. Commercial Development proponents wanting more than one Driveway access to a public Street will be required to justify the second Driveway on the basis of Development generated trips. 4. Where the Driveway location does not meet minimum separation criteria, or where a safe Driveway location cannot be obtained, the City will require appropriate mitigation measures to provide for a Driveway as safe as feasible. Acceptable mitigation may take the form of turning movement restrictions or a Joint-Use Driveway with the adjoining property owner. 5. The minimum Protected Driveway Throat without any turning movements or parking allowed must be provided for the number of vehicles indicated below to prevent any potential turning conflicts within their lengths. These are the minimum lengths that will be permitted, unless an approved traffic study includes a Site and Project specific queuing study showing that either more or less throat length is required to serve the subject Development. a. For single-lane drive-thru banks: storage to accommodate a minimum entering queue of 4 vehicles for a single window; banks having two lanes need to accommodate a minimum entering queue of at least 3 vehicles per window or 10 vehicles total; and banks having 3 or more lanes shall have storage to accommodate a minimum of 3 vehicles for each service lane or total vehicles equal to four times the number of service lanes. 6-12 205 b.

For service stations: a minimum entering and exiting storage length to accommodate a minimum of 2 vehicles shall be provided between the pump islands and the public Right-of-Way. If an espresso stand is located on-site with drive-thru windows, the minimum espresso stand storage requirements will prevail. 7. For shopping centers having 50,000 square feet or more of gross leasing area shall have an entering and exiting throat length to accommodate a minimum of 4 vehicles shall be provided before any crossing or turning conflicts can be permitted between the parking lot and the public Right-of-Way. Shopping centers having 100,000 square feet or more of gross leasing area shall provide a Site and Project specific queuing analysis to determine their appropriate entering and exiting storage lengths. 8. For all Commercial Developments (less than 50,000 square feet of gross leasing area): a minimum entering and exiting storage length to accommodate at least 2 vehicles shall be provided between the parking lot and the public Right-of-Way before any crossing or turning conflicts can be permitted. Note: the City may require a Site and Project specific queuing analysis to determine the appropriate storage lengths when the Commercial Development includes one or more drive through facilities. a. For all espresso stands with drive-thru windows, entering and exiting storage lengths shall accommodate a minimum of 4 vehicles per window. b. For pharmacies with drive-through service: entering and exiting storage lengths shall accommodate a minimum of 3 vehicles per service point. c. For all other facilities, a minimum entering and exiting storage length of 2 vehicles shall be provided before any crossing, or turning conflicts can be permitted between the parking lot and the public right-of-way line. 6.4.E Traffic Calming All new residential streets shall include Traffic Calming Measures. These measures include but are not limited to curb bulb-outs, alternating parking, chokers, entrance gateways, landscaped medians, speed cushions, traffic circles, and raised Intersections. 6-13 206 Minimum Traffic Calming Measures shall be determined by the Engineer in collaboration with the Developer based on the Site's constraints such as topography, size, and location. At a minimum, all subdivisions (more than 9 lots) shall have an entrance gateway if connected to an Arterial Street and all internal Intersections and streets longer than 500 feet shall incorporate at least one measure such as curb bulb-outs, chokers, or speed cushions unless otherwise approved by the Engineer. Standard Plans 6-24 through 6-30 All landscaping shall be maintained by a homeowners association or other responsible entity or parties including all benefited property owners. For details of the different Traffic Calming Measures, see 6.5 Driveways, Sidewalks and Non-Motorized Lanes or Trails The following standards outline the appropriate parameters for Driveways, sidewalks and non-motorized lanes or trails: 6.5.A Driveways Driveway design standards are shown in the Standard Plans 6-42 through 6-48. The required radius and minimum Protected Driveway Throat width shall be determined by a vehicle maneuvering diagram provided by the Developer for the appropriate Design Vehicle. Pedestrian and vehicular sight line requirements shall be met and shown on Engineering Plans per Standard Plans 6-52 & 6-53. All Driveways shall be designed with Profile Grade breaks, or transitions, constructed as vertical curves to ensure adequate clearance for all vehicles. The maximum change in longitudinal Profile Grade for a Driveway shall be 12% in a sag condition, and 8% in a crest condition. The maximum longitudinal Profile Grade for Driveways shall be 12%, unless otherwise required by existing conditions as approved by the Engineer. The minimum length of vertical curve shall be 5' per 1% change in Profile Grade. See Standard Plan 6-48. The minimum separation between street light standards and single-family residential Driveways shall be 5'. The minimum separation from all other Driveways shall be at least 15'. The minimum width for all Driveways to commercial, multi-family residential or industrial land uses shall be 30' unless otherwise approved by the Engineer in order to accommodate higher volumes of pedestrians in a safe and convenient manner. The width of Driveways to industrial and commercial properties may be required to be increased in order to accommodate large wheel-base vehicles. The use of one-way Driveways as a part of the on-site circulation pattern is discouraged. One-way Driveways are reviewed on a case-by-case basis for impacts to the City roadway system. If the use of one-way Driveways is allowed, the minimum width of each one-way Driveway shall be 20'. In 6-14 207 addition, signs shall be posted at the Driveways indicating the permitted movement (i.e. "Entrance Only" or "Exit Only - Do Not Enter." The Engineer may also require similar signs to be posted within the on-site parking areas or drive aisles. See Standard Plans 6-43 & 6-44. 1. Private Residential Driveways: Driveways serving a single-family residential lot shall be considered Private Residential Driveways. Private Residential Driveways shall be constructed of hot mix asphalt or cement concrete pavement at least 12' in width at the curb line unless otherwise directed by the Fire Marshall. At a minimum, the pavement for the Driveway shall extend from the edge of the Right-of-Way of the public or private Street serving that Driveway, 40' or to the front face of the carport or garage, whichever is less. See Standard Plan 6-42. 2. Private Joint Use Residential Driveways: Driveways serving two single-family residential lots shall be considered Private Joint Use Residential Driveways. Private Joint Use Residential Driveways must be constructed with hot mix asphalt or cement concrete pavement at least 16' in width unless otherwise directed by the Fire Marshall. Private Use Joint Driveways shall be centered within a private Tract for Ingress/Egress and utilities that is at least 4' wider than the pavement width. At a minimum, the pavement for the Driveway shall extend from the edge of the Right-of-Way of the public or private Street serving that Driveway, 40' or to the front face of the carport or garage, whichever is less. See Standard Plan 6-47. 6.5.113 Sidewalks An important element of the City's Transportation Master Plan is the provisions of facilities for pedestrian use. Sidewalks shall be provided on all new and improved City streets. Sidewalks shall be constructed of Portland Cement Concrete Class 3000. The minimum width for sidewalks varies depending on the functional classification of the Street. On Arterial Streets, and any Street adjacent to major pedestrian activity centers (retail districts and businesses, churches, schools, other public gathering places), the minimum width for sidewalks shall be 5' with a landscape planter and 10' without a landscape planter. See the Standard Plans for detailed information based on roadway classification. In instances where building doors open directly to a public sidewalk, the minimum sidewalk width shall be 10'. No street trees will be allowed within 4' of a door opening to a public sidewalk. These widths shall be exclusive of the width of any adjacent curbs, and shall be free of obstructions such as utility poles and mailboxes. Sidewalks will be required to be constructed on both sides of a Street, and shall be placed as shown in the Standard Plans for the various Street classifications. Where sidewalks are not adjacent to the curb, a landscaped planter strip between the street curb and the street-side edge of the sidewalk shall be provided. 6-15 208 The minimum thickness for Portland cement concrete sidewalks shall be four 4", except at Driveway approaches where the minimum thickness required shall be 6" for residential Driveways and 8" for commercial/industrial Driveways. See Standard Plans 6-42 through 6-46. All streets constructed with curbs, gutters, and sidewalks, shall have Americans with Disabilities Act (ADA) compliant curb ramps provided at Street Intersections and other pedestrian crossings. These ramps shall be located and constructed in accordance with WSDOT Standard Plans. The City requires detectable warning as truncated domes. Material shall be Federal Yellow composite cast-in-place panels. No painted concrete stamps will be allowed. 6.5.0 Non-Motorized Lanes or Trails 1. Bike Lanes Bike lanes are a portion of the Street that has been designated by signs and pavement markings for preferential or exclusive use by bicyclists. These lanes shall be 5' wide, located next to the curb, and delineated with pavement markings. The route shall be signed with the diamond shaped bicycle symbol (W11-1) and "Share the Road" (W16-1) signs according to the MUTCD. See Standard Plan 6-31. 2. Facilities Containing Bicycle Components: All bicycle facilities shall be designed and constructed according to the latest version of the Guide for the Development of Bicycle Facilities, published by AASHTO and these Standards. In general, a minimum Design Speed of 20 mph should be used for bike paths/trails. When downgrades exceed 4%, a Design Speed of 30 mph or more may be required. Grades on shared use paths/trails should be kept to a minimum, especially on long inclines. Grades greater than 5% are undesirable. 3. Shared Travel Lane: Shared Travel Lanes are within the outside travel lanes of a Street next to the curb. This lane is widened 4' to accommodate the shared usage by vehicles and bicycles. Bicycle route signing is required on these streets. The route shall be signed with the diamond shaped bicycle symbol (W11-1) and "Share the Road" (W16-1) signs according to the MUTCD. See Standard Plan 6-31. 4. Shared Use Trails (Pedestrian and Bicyclist): The minimum surface width of asphalt pavement is 10' for a two-way trail. Each trail shall include provisions for 2' wide gravel Shoulders having cross-slopes no steeper than 2% on both sides of the trail. The minimum horizontal clearance shall be at least 3' from the edge of the asphalt paved trail to any trail-side obstruction. Where trails are adjacent to ditches, creeks, or slopes steeper than 2H:1V, the gravel Shoulder must be 5' wide with a minimum 6' high 6-16 209 vinyl covered chain link fence, where appropriate, as the means to ensure that bicyclists remain safely away from such trail-side hazards. 6.6 Intersection Design Policies Intersection design policies are outlined in the tables below: 6.6.A Intersections Design Table 6.2 Design Criteria Standard 1. Angle of intersection measured at 10' beyond street Minimum 850 right-of-way line Maximum 950 2. Minimum centerline radius (2-lane) for residential 55 Feet streets 3. Minimum curb radius a.

New Intersections shall be designed to avoid intersection angles at Street centerline of less than 85 degrees, or more than 95 degrees. Offsets between intersections shall not measure less than what is shown in the Street Design Standards Table 6.7. 6.6.G Intersections Within a Horizontal Curve Alignment The use of Intersections in or near a horizontal curve shall be avoided wherever possible, especially on the inside of a horizontal curve. Intersection/Driveway Sight Triangle standards shall be met as required in these Standards. 6.6.H Intersection Pedestrian and ADA Compliant Access ADA compliant ramps shall be provided on each corner of an Intersection from which pedestrian movement is permitted. Ramps shall be designed in accordance with these Standards and the ADA. See WSDOT Standard Plans. At those locations where sidewalks are not required and are not proposed to be installed, a concrete pedestrian refuge area may be required behind, and to either side of, the pedestrian/wheelchair ramp. This refuge area shall extend a minimum of four 4' clear behind the ramp, and eight 8' on both sides of the edges of the ramp. Crosswalks may be installed typically under the following conditions: 1) at signalized Intersections; 2) at any Intersection located along formally established "School Routes" or at locations approved by the Engineer. 6-18 211 6.6.I. Intersection Turn Lane Vehicular Storage Intersection turn lane storage shall be a minimum of 50'. When a traffic study is required by the City, the turn lane storage shall be designed on the basis of 85% of the queue length during the PM peak hour for 20-year forecast volumes. The analysis shall be based on signal optimization and analysis program calculations from the Transportation Research Board's Highway Capacity Manual or computerized analysis programs, such as McTran's HCS+ software or an equivalent program approved by the Engineer. 6.6.3 Intersection Drainage Intersections should be designed to avoid the sheet flow of water across the intersection of all streets classified as Arterial Streets. Where practical, runoff water should be carried under the Intersection via catch basins and storm drains. Storm water shall be collected prior to a curb ramp and shall not be allowed to pool or puddle in front of or within a curb ramp. Where appropriate the use of low-impact Development design and materials to handle storm water is encouraged. 6.6.K Intersection Right-of-Way Requirement The right-of-way requirements for Intersection approaches may be increased for such special intersection elements as raised median channelization, multiple left-turn lanes, exclusive and/or right turn lanes, turn lanes to accommodate large wheel base vehicles, bus turn outs, etc. 6.6.L Intersection/Driveway Sight Triangle Requirements Intersection/Driveway Sight Triangle will be evaluated based upon the current edition of the AASHTO Policy on the Geometric Design of Highways and Streets. Sight distance requirements for each approach will be those indicated in the appropriate table in the latest edition. The City may allow mixed-use Developments to use wider sidewalks to accommodate sight lines at Intersections on a case-by-case basis. 6.6.M Intersection Channelization Intersection turn islands (right turn islands) shall be constructed with raised curbs only when the resulting island encompasses an area of at least 100 square feet (exclusive of the area removed for pedestrian ramps), or if at least two of the sides of the island are a minimum of 15' long. The curbing shall be offset at least two 2' from the right edge of the through travel lanes, and at least four 4' from the left edge of the right turn lane. The curb shall be combined curb and gutter in all new installations and pre-cast concrete mountable curb sections in all retrofit installations. A minimum radius of 2' shall be used for the island noses. Landscaping should not be installed in right turn islands. The preferred surfacing materials shall be four 4" thick section of broom-finished concrete or a three 3" thick surface of asphalt concrete. Stamped colored 6-19 212 concrete may be approved by the Engineer on a case-by-case basis, provided it is not used in a pedestrian pathway portion of the island. A Type 2 object marker 6" x 12", white background with 3" diameter yellow reflectors shall be installed facing the approaching traffic. The marker should be installed horizontally, and mounted at a height of no less than four 4', above the finished surface of the nearest traffic lane (See MUTCD 3C-01). Divisional center medians (used between left-turn lanes and opposing traffic lanes) shall be a minimum of four 4' wide and one hundred 100' long. Curbing for the median shall be combined vertical curb and gutter. A type R4-7 (Keep Right - symbol) sign, and a Type 1 object marker (yellow diamond panel with nine (9) reflective markers) shall be installed at the nose of all divisional center medians, facing approaching traffic. The signs shall be mounted with the R4-7 sign above the object marker sign, and mounted on metal posts. The posts may not be installed more than 15' behind the nose of the median. The sizes of the signs shall be as follows: R4-7 - 24" x 30", Type 1 object marker - 18"x 18". 6.6.N Traffic Signal Equipment One (1) Four inch (4") and two (2) two-inch diameter traffic signal conduits with pull ropes terminating in Type 2 junction boxes shall be installed under each leg of the Intersection for future traffic signal installation, as required by the Engineer. Traffic signal controller cabinets, when installed as a part of a signal installation, shall be installed so that the door to the cabinet opens towards the Intersection whenever possible. A clearance of 7' shall be provided from the face of curb to the controller cabinet. Poles shall be located no more than 5' (as measured to the pole centerline) from the edge of the nearest pedestrian/wheelchair ramps on that quadrant of the Intersection. See Standard Plan 6-38. 6.6.0 Railroad Crossings for New Construction Adjacent Driveways shall be located at least 100' from any railroad crossings measured from the centerline of the track to the nearest edge of the Driveway. Intersections shall not be located within two hundred 200' of a railroad crossing, measured from the centerline of track to the nearest intersection curb return. At those locations where this separation cannot be provided, special traffic control measures may be required to be installed in the individual approaches to the Intersection. Such measures may include, but not be limited to, the installation of the applicable railroad crossing warning signs, median barriers, and the installation of traffic signals interconnected to automatic crossing protection devices. Where the crossing is immediately adjacent to the Intersection, the Engineer may require special intersection design and crossing protection 6-20 213 to enhance the safety of vehicles traveling through or turning at the Intersection. Street cross-sections (pavement width, curbs, gutters, sidewalks, planter strips and a utility strip) will be the same across railroads with some modifications to turn lanes, planter strips and sidewalks to accommodate railroad equipment. Sight distance requirements for the railroad crossing will be those indicated in the appropriate table in the latest edition of the AASHTO Policy on the Geometric Design of Highways and Streets. All removable obstructions shall be removed or relocated from the defined sight triangle, except for warning signs, luminaire poles, or other officially established traffic control devices. Where these sight distance requirements cannot be met because of pre-existing, or non-removable obstructions (buildings, for example) automatic crossing protection shall be installed. 6.6.P Intersection Geometric Design Every Intersection shall be designed to accommodate the design vehicle appropriate for the highest classified street forming the Intersection. All elements of the Intersection, including turning lanes medians, and islands, shall be designed so that the design vehicle will not encroach onto curbs, sidewalks, traffic control devices, islands, center medians, or encroach into the travel lanes of opposing flow traffic. 6.6.Q Vehicle Maneuvering Diagrams The Vehicle Maneuvering Diagrams (VMD) shall clearly show the outermost and innermost wheel paths and vehicle overhangs of the specified design vehicle using the Intersection for entering or leaving a Project site, traversing the Site, backing into a dock, or otherwise maneuvering for delivery. The VMD shall show the design vehicle using the curb lane in multiple lane roadways or Driveways to enter and leave the Site. The VMD shall show that the appropriate design vehicle wheel paths/vehicle overhangs are without encroachment into: 1. An opposing lane of traffic in a public Street. The outside wheel paths shall be at least 1' inside the curb or edge of outside traffic lane when entering and exiting the Site on a two or three lane Street. 2. An opposing lane of a two-way Driveway. Adjacent wheel paths of entering and exiting design vehicles should show at least 3' of minimum separation within Driveways. 3. Any parking stalls. No design vehicle wheel path shall be within 3' of any required parking stalls. 4. Areas outside of the reinforced concrete Driveway approach apron and Protected Driveway Throat. The inside wheel paths for entering and exiting design vehicles should be at least 3' inside the reinforced concrete Driveway approach apron. 6-21 214 The VMD shall show required minimum Protected Driveway Throat lengths prior to exiting the Development, and shall show that no portion of the minimum throat length will be within the Driveway aisle abutting required parking stalls. All commercial and industrial Project sites shall provide at least 50' of protected throat length from the exiting Driveway apron. Sites which will experience more than 1000 vehicles per peak-hour, and sites with a heavy percentage of truck traffic will require a traffic study documenting the minimum protected throat length to accommodate the expect queue. The VMD shall clearly identify the applicable design vehicle(s) used to prepare the VMD. The applicable design vehicle shall be based on the typical delivery vehicle serving the Site as approved by the Engineer. See the Standard Plans 6-101 through 6-105 for turning movements radii associated with the various design vehicles. When no specific design vehicle is specified for a Development, the appropriate design vehicle shall be the BUS-40 design vehicle. The BUS- 40 design vehicle is used for service vehicles such as garbage trucks, and fire trucks. 6.7 Bridge Cross Section Bridges shall be structurally designed to WSDOT Standards. The street section across a bridge or major Culvert shall remain as shown in the Standard Plans with the exception that turn lanes, planter strips and utility strips may not be required. Turn lanes shall be reduced using the MUTCD taper formulas and a 15' taper will be required for pedestrian sidewalks or multi-use trails to bring the sidewalk adjacent to the curb and eliminate the planter strip. All tapers shall occur off of the bridge or Culvert structure. All utility systems shall be in steel casings and placed between the structural beams using approved hangers so that piping is hidden from view. No carrier lines, casings, or conduits will be allowed on the outside of the structural beams. All know utilities and future upgrades shall be accounted for in the design. In addition, two (2) four-inch (4") and two (2) two-inch (2") diameter conduits and one (1) eight-inch (8") diameter steel casing shall be installed for future use. Design of the utility system hangers shall be for a full pipe condition for all utilities crossing a bridge. 6.8 Street Median Channelization Median channelization may be required to be installed as a part of any Project. In general, median channelization will not be required or approved for local residential streets or for Arterial Streets where the resulting median would be less than 600' long inclusive of any turn lane storage area. Exceptions may include the installation of median channelization at Intersections to prevent left-turn access into or out of properties in the immediate vicinity of an Intersection. Median 6-22 215 channelization must be at least 4' wide in order to accommodate any necessary traffic control devices and/or street lights. Approval of the installation of medians will be made by the Engineer. Design plans which include median installation must be accompanied by an access plan for the impacted properties. This access plan shall denote the ownerships, uses of the directly impacted properties, and the resulting changes to the access to and from these properties. If median channelization is required and approved with landscaping on residential collector and residential streets, the landscaping must be maintained by the homeowners association or other responsible entity or parties including all benefited property owners and a landscape maintenance agreement would be required. All costs of maintenance including irrigation shall be the responsibility of the home owners. The maintenance agreement will include the responsibility to maintain adequate sight distance for vehicular traffic, and shall be recorded with the County Auditor's Office. Type IV Landscaping shall be provided including an irrigation system with separate meter per Standard Plan 3-15. All plantings shall not restrict sight distance of the vehicles using the Street at plant maturity. The landscaping shall not include large rocks, boulders, or other fixed obstructions. Street trees shall be selected from the approved street tree list shown in Appendix A. Placement of landscaping shall be such that adequate sight distance, per these Standards and AASHTO requirements, will be maintained. All landscaped medians shall be provided with fully automatic, underground irrigation systems. No left-turn access breaks in a "continuous" center median island will be permitted within the intersection spacing limits as shown in Section 6.6.B. 6.9 Cul-de-sac/ Hammerhead Standards Provisions for vehicle turn-arounds must be made for either temporary or permanent non-through street conditions. The minimum radius for a Cul-de-Sac shall be 45', as measured from the center of the Cul-de-Sac to the face of curb. The maximum cross section Profile Grade for a Cul-de-Sac is 6%. Cross grades greater than 2% may only be used when the existing topography exceeds 10% in Profile Grade. See Standard Plan 6-18. A" Hammerhead Turnaround" may be permitted if • The Street is a private Street and is more than 150 feet from the nearest face of curb or edge of pavement of the connecting Street to its most distant point • The Street is a public Street that will be extended in the future • Parking and Driveways are not allowed within a turnaround See Standard Plan 6-21. The maximum length of a non-through street, either permanent or temporary, shall be 600' measured from the centerline of the connecting Street to its most distant point. 6-23 216 6.10 Fire Access Streets Fire access streets are required to serve all buildings that have exterior walls located more than 150 feet from the nearest face of curb or edge of pavement of the connecting Street. The distance is measured by an approved route around the exterior of the building that a firefighter would take, and does not allow topographical or property separation conditions that would make it impossible to advance hose lines to the proposed building along that route. Fire access roads are also required to serve properties such as wrecking yards, lumber yards, parking lots and similar uses on lots where structures or buildings may not exist. All fire access roads shall be a minimum of 20' in width, and shall have an unobstructed height of no less than 13' 6". The minimum inside turning radius for a fire access street is 30' for both left and right turns, and a minimum outside turning radius of 50'. Any fire access Street in excess of 150 feet from the nearest face of curb or edge of pavement of the connecting Street shall be provided with a turnaround at the end meeting the requirements of Section 6.9 Cul-de-sac/Hammerhead Standards. Fire access roads must support emergency vehicles on an all-weather basis. This means that it must have a firm gravel base with hot mix asphalt concrete pavement or cement concrete pavement above the gravel base, and it must be designed so that it will not deteriorate under adverse weather conditions and fire vehicle traffic. The maximum Profile Grade for paved surface fire access streets is 12%, unless otherwise approved by the Fire Marshal. Homes that have access at 12% Profile Grade or greater are required to have sprinkler systems per NFPA 13 standards. Paved fire access roads for residential structures may be accepted up to a maximum Profile Grade of 15 % when all structures have sprinklers, provided that in the professional opinion of the Fire Marshal, fire fighting and rescue operations will not be impaired.

The improved Street shall have a remaining service life of 20 years. The Developer shall cold mill (grind) and overlay, at a minimum depth of 2", one half of the Street fronting the Development unless otherwise directed by the Engineer. The improved pavement section may consist of all new pavement or a portion of existing pavement and new pavement overlay to achieve the required remaining service life of 20 years. Pavement analysis and design shall be consistent with Part II and Part III of the AASHTO Guide for Design of Pavement Sections, latest edition, and the pavement analysis report shall provide all of the necessary information required by the design guide. 6-36 229 In addition to the pavement analysis and design discussed above, the completed street improvement shall provide a 2% transverse side slope from the existing centerline crown point. When the existing crown location does not coincide with the required street centerline, or the 2% transverse side slopes of existing pavement are not available, the Developer is required to grind and provide an asphalt overlay at a minimum depth of 2" to achieve the 2% transverse side slope.. Prior to construction of the asphalt overlays, any failed pavement sections within the improvement limits will also be removed and permanently patched by the Developer according to the requirements of these Standards. See Standard Plans 6-64 through 6-69. When an existing asphalt pavement is used, the Developer shall remove at least the outer 1' of the existing asphalt pavement to provide a strong and straight edge for the new asphalt to match. The actual outside line for this asphalt pavement removal will be determined on-site by the Engineer to ensure that all inadequate and failing pavement is removed. When an asphalt overlay occurs adjacent to an existing concrete curb and gutter, the Developer is required to install the new asphalt pavement flush with the existing curb and gutter. The Developer will do this by cold milling (grinding) a minimum 4' wide strip of pavement immediately abutting the concrete curb and gutter. The minimum depth of this grinding shall be 2" and shall leave a minimum 2" of existing pavement in place. Should there be less than 2" of remaining asphalt pavement the Developer shall remove and replace the outer 4' of asphalt pavement. When the surface of the existing street pavement is determined, by the Engineer, to be too rough or irregular, the Developer shall provide an asphalt overlay, cold milling, or a combination of the two, to provide an acceptable riding surface for the improved public Street. 6.16.A Pavement Design See the Standard Plans for detailed pavement design information and minimum pavement sections. Portland cement concrete streets may be considered as an acceptable alternative to asphalt concrete streets for most street classifications. Specific approval by the Engineer is required prior to design of concrete streets. Porous pavements may also be considered for low traffic volume private residential streets and Driveways. Porous pavement is a permeable paving material which allows stormwater to percolate through the pavement to the gravel base. The pavement consists of a uniform, open- graded coarse aggregate, cemented together with either concrete or asphalt. Water reaching the gravel base either infiltrates into the soil or is routed to the conveyance systems via underdrains. The Developer must sign a maintenance agreement confirming that the Development will be 6-37 230 required to bi-annually vacuum sweep the pavement surface followed by a high pressure wash. 6.16.113 Pavement Construction All pavement construction shall be in accordance with the WSDOT Standard Specifications except as modified herein. When asphalt concrete is placed in lifts, tack coat in accordance with the WSDOT Standard Specifications shall be used unless the lifts are placed on the same day, and approved by the Engineer. In areas where soft subgrades require stabilization, approved geotextile fabric and/or soil stabilizing may be used. Ballast material may also be used where necessary. 6.16.0 Materials Certifications and Compaction Tests All construction activities shall meet the materials certifications and Compaction testing requirements on the WSDOT Standard Specifications. compaction tests shall be performed by an approved geotechnical or testing firm under the direction of a Professional Engineer registered in the State of Washington under contract with the City. Copies of the reports shall be furnished to the City of Kent Inspector. 6.17 All Utilities Within City Right-of-Way Utility systems to be located within existing and proposed Right-of-Way shall be constructed in accordance with current franchise and/or permit requirements, and in compliance with these Standards. In their use of the Right-of-Way, utilities will be given consideration in accordance with the traffic-carrying requirements of the Street which are, namely, to provide safe, efficient and convenient passage for motor vehicles, pedestrians, bicycles, and other transportation uses. Aesthetics shall be a consideration. Underground installation of electric and telecommunication utilities will be strongly encouraged, particularly in urban Development. Utilities are subject to City Codes and policies relating to drainage, erosion/sedimentation control and sensitive areas as set forth in the Chapter 5 of these Standards and the City's Surface Water Design Manual. Placement of permanent structures or objects for franchised utilities that block ready access to City utilities and the connected Appurtenances shall not be allowed, unless otherwise approved by the Engineer. It is the responsibility of the Developer to verify the location of all existing and proposed underground and aerial utilities prior to design. The Developer shall coordinate the design with the respective Utility. Those existing utilities in conflict with any of the Project street improvements shall be relocated at the Owner/Developer's expense. All properties adjacent to a new Street shall be provided with water, sanitary sewer, storm drainage, and private utility service in such a manner as to avoid future 6-38 231 street improvements and the associated disruptions to traffic. The number and location of service "stub outs" to be installed shall be based upon the lot configuration of the properties adjacent to the proposed street improvements. All overhead electrical and/or communication utilities shall be placed underground if the criteria for undergrounding are met per the requirements of the KCC 7.10. All permits for new placement and replacement of existing utility poles, and other utility system structures above Grade, shall be accompanied by written certification from the Utility's Professional Engineer or from an agent authorized by the Utility. They must certify that the installations conform to these Standards, and that the proposed Work is in conformity with sound Engineering principles relating to highway safety. 6.17.A Standard Utility Locations Within the Right-of-Way Utilities within the Right-of-Way on new streets, or on streets where existing topography, utilities or storm drains are not in conflict, shall be located as indicated below. Where existing utilities or storm drains are in place, new utilities shall conform to these Standards as closely as practicable and still be compatible with the existing installations. Above- ground utilities located within Intersections shall be placed so as to avoid conflict with placement of curb ramps and signal poles. Mains and service connections to all lots shall be completed prior to placing of surface materials. 1. Gas and Water Lines: a. Curb and Gutter Section: Preferable: 1.5' back of curb, or at distance which will clear root masses of street trees if these are present or anticipated. Otherwise: In the Street as close to the curb as practical without encroachment into the storm drainage system. b. Designated Side of Centerline: GAS: Preferable south and west. WATER: Preferable north and east. c. Depth: 36" minimum cover from Finished Grade, ditch bottom or natural ground. 2. Individual water service lines and side sewers shall: a. Be placed with minimum 36" cover from finished Grade, ditch bottom or natural ground. b. Use Right-of-Way only as necessary to make side connections. c. For any one connection, do not extend more than 60' along or through the Right-of-Way, or the minimum width of the existing Right-of-Way. d. Water meter boxes, when placed or replaced, shall be located on the right-of-way line immediately adjacent to the property being served, unless otherwise approved by the Engineer. 6-39 232 3. Sanitary Sewers: a. In general, 5' south and west of centerline; depth 36" minimum cover from Finished Grade, ditch bottom or natural ground. b. Side sewers shall be provided to all adjacent lots or parcels. c. Side sewers shall be placed perpendicular to street centerline. d. Existing parcels with potential for future Development based on the existing zoning shall be provided with a minimum 8"0 pipe from the manhole to the cleanout at the right-of-way line at the lowest point adjacent to the main along the parcel frontage. 4. Force Main Sanitary Sewers: In the case of individual sanitary sewer service lines, which are force mains, the pipe shall: a. Be a minimum two (2) inch inside diameter, or as required by the Utility to maintain internal scouring velocity. b. If nonmetallic, contain wire or other acceptable proximity detection features; or be placed in a cast iron or other acceptable metal casing. c. Be placed with minimum Thirty-six (36) inches cover from Finished Grade, ditch bottom or natural ground, within 100 of perpendicular to street centerline, and extend to right-of-way line. d. Bored under Street, unless otherwise approved by the Engineer. e. Sanitary sewer and water lines shall be separated 10' horizontally and 1.5' vertically in accordance with the latest edition of the Criteria for Sewage Work Design by the DOE. f. Gravity systems, whether sanitary or storm drainage, shall have precedence over other systems in planning and installation, except where a non-gravity system has already been installed under previous approved Permit and subject to applicable provisions of such permits or franchises. 5. Utilities Electric utilities, power, telephone, cable TV, fiber optic conduit: Preferably, underground with 36" minimum cover, either side of Street, under or behind the sidewalk, at plan location and depth compatible with other utilities and storm drains. Otherwise, every new placement and every replacement of existing utility poles and other utility system structures above Grade shall conform to the following: Utility poles, traffic signal poles or other approved essential roadside obstacles may be placed within the Right-of-Way, and shall be as far back from the Traveled Way or Auxiliary Lane as practicable. When allowed, they shall be located as follows: 6-40 233 a. On shoulder-type or mountable curb streets, installation of new or relocated poles or obstacles shall be located behind existing ditches and in accordance with the criteria in this Section and Standard Plan 6-50. Placement of a guard rail or traffic barrier between the Traveled Way and the pole or obstacle shall not satisfy this requirement, unless the guard rail or barrier already exists for other purposes and the pole provides a minimum of 3.5' separation from the barrier. Deviations will be considered only when other reasonable alternatives do not exist. b. On vertical curb-type streets with a speed limit less than 40 mph, poles or obstacles shall be placed clear of sidewalks and at least 10' from face of curb to face of obstacle in commercial/business areas and in the planter strip at 3' from face of curb to face of obstacle in residential areas. On urban streets with speed limits of 40 mph or greater, hazardous objects shall be placed as close to the right-of-way line as practicable, and a minimum of 10' from the edge of the Traveled Way, face of curb or edge line to the face of obstacle and in accordance with Standard Plan 6-50. c. Notwithstanding other provisions regarding pole locations described in these Standards, no pole shall be located so that it poses a hazard to the general public. Utilities shall place and replace poles with primary consideration given to public safety. Existing utility poles, in locations that do not comply with these Standards, and are damaged through vehicle collision, shall be considered a hazard by the City and be relocated by the Utility, at their expense, in accordance with these Standards. Additionally, existing utility poles that do comply with these Standards and are damaged through vehicle collision more than 3 times in any 10 year period shall be relocated by the responsible Utility as approved by the Engineer at their expense. d. Every effort shall be made to meet these Standards during emergency replacement of existing utility poles and other structures. After a pole has been replaced, all utilities sharing that pole shall have a maximum of 180 days to relocate their facilities to the new pole and remove the old pole. e. The above constraints on pole and obstacle location will not apply to locations not accessible by moving vehicles, "Breakaway Structures" whose break-off resistance does not exceed that of a single 4" x 4" wood post or a 1.5" standard (hollow) iron pipe, or to "breakaway" fire hydrants installed according to manufacturer's specifications. f. For franchised utility permits, the Utility must request any deviation from pole and obstacle clearance criteria in accordance with Section 1.17 Design Deviations. Up to three contiguous damaged or weakened poles may be replaced at existing locations in accordance with emergency procedures. However, sequential permits resulting in continuous replacement of a pole line shall not 6-41 234 be allowed. A pole or other obstacle, which incurs repeated damage from errant vehicles, shall be relocated outside the Clear Zone. See Standard Plan 6-51. g. Locations of poles shall also be compatible with Driveways, Intersections, street trees, underground utilities, and other street features (i.e., they shall not interfere with sight distances, street signing, traffic signals, Culverts, etc.). To the extent possible, utilities shall share facilities so that a minimum number of poles are needed. h. Where street uses leave insufficient overhang, anchor, and tree- trimming space for overhead utilities, additional easements and/or Right-of-Way may be required to accommodate the utilities. The costs associated with additional easements and/or Right-of-Way for this purpose shall be borne by the Developer, Utility, builder, or other party initiating the improvement. The associated cost of relocating the utility system shall not be borne by the City. i. Notwithstanding other provisions, underground systems shall be located at least 5' away from the Street centerline. Additionally, the underground systems shall not disturb existing survey monuments, unless there is no reasonable alternative. 6.17.113 Utility Underground Installations All hard surface street crossings shall be jacked or bored. Exceptions will be on a case-by-case basis with the approval of the Engineer. The current WSDOT Standard Specifications, Sections 7-08 and 7-08.3(3) will generally apply, unless otherwise stated. 1. New Street Construction, Reconstruction and Widening: a. Cuts on Traveled Way: When approved, the open cut shall be a neat-line cut made by saw-cutting a continuous line. Trench sides shall be kept as nearly vertical as possible. Compaction and restoration must be done as detailed below and immediately after the trench is backfilled, so as to cause least disruption to traffic. The asphalt or cement pavement shall be cut a minimum of 1' beyond all edges of the trench. See Standard Plans 6-64 through 6-69. On crossings required to be opened to traffic, and prior to final trench restoration, steel plates shall be installed by the contractor, as directed by the Engineer. b. Cuts parallel and traverse to Street alignment: The entire trench backfill depth must meet 95% of the maximum density compaction as determined by the compaction control tests described in Section 2-03.3(14)D of the WSDOT Standard Specifications. 6-42 235 Regardless of trench depth, the backfill material shall meet the requirements for Gravel Borrow per Section 9-03.14(1) of the WSDOT Standard Specifications. When the material remaining in the trench bottom is unsuitable, the Excavation shall be continued to such additional depth and width as required by the Inspector. After Backfill and Compaction, an immediate cold mix patch shall be placed and maintained in good drivable condition acceptable to the Engineer. On asphalt pavement, a permanent hot mix patch the same thickness as the existing asphalt or a minimum of 2", whichever is greater, shall be placed and sealed with a paving grade asphalt within 7 calendar days on Arterial Streets and in the downtown area overlay and within 30 calendar days on all other streets. Cement concrete pavement shall be restored in accordance with Section 5-05.3(22) of the WSDOT Standard Specifications within the same time parameters stated above. Backfill material outside the street prism may be the excavated material as long as it is free of wood waste, debris, clods and/or any rocks exceeding 6" in any dimension and meets the Compaction requirements of Section 2-03.3(14)C of the WSDOT Standard Specifications. 2. Existing Streets: a. Cuts on Traveled Way: All hard surface street crossings shall be jacked or bored. Exceptions will be on a case-by-case basis with the approval of the Engineer, if it can be shown that Boring is not feasible due to conflicts or soil conditions, or unless the utility system, including drainage structures, can be installed just prior to reconstruction or overlay of the Street by a City Capital Improvement Project. When approved, the open cut shall be a neat-line cut made by saw-cutting a continuous line. Trench sides shall be kept as nearly vertical as possible. Compaction and restoration must be done as detailed below and immediately after the trench is backfilled, so as to cause least disruption to traffic. The asphalt or cement pavement shall be cut a minimum of 1' beyond all edges of the trench. See Standard Plans 6-64 through 6-69. b. Cuts Parallel to Street Alignment: In cuts parallel to the street alignment, the entire trench Excavation and restoration shall meet the requirements of Section 6.17.B.1b of these Standards. The restoration shall include, but is not limited to, repairing all failures and cracking of the paved surface, repairing failures caused by the construction activity, rebuilding the cross slope to uniformity, and overlaying the area where the pavement was removed. 6-43 236 c. Cuts Transverse to Street Alignment: 1. Without exception, the entire trench shall be backfilled with Crushed Surfacing Top Course meeting the requirements of Section 9-03.9(3) or Controlled Density Fill meeting the requirements of Section 2-09.3(1)E of the WSDOT Standard Specifications. Backfill shall be placed and compacted mechanically in 6" lifts to 95% of the maximum density as determined by the compaction control tests described in Section 2-03.3(14)D of the WSDOT Standard Specifications. If the capability can be demonstrated, based on compaction equipment or quality of Backfill to achieve 95% density in thicker lifts, the depth of Backfill lifts may be increased up to 1'. If the Inspector approves use of Controlled Density Fill (CDF), it shall meet the requirements of Section 6.17.13.3 of these Standards. 2. After Backfill and Compaction, an immediate cold mix patch shall be placed and maintained in a drivable condition acceptable to the Engineer. On asphalt pavement, a permanent hot mix patch the same thickness as the existing asphalt or a minimum of 2", whichever is the greater, shall be placed and sealed with a paving grade asphalt within 7 calendar days on Arterial Streets and within the downtown area overlay, and within 30 calendar days on all other streets. Cement concrete pavement shall be restored in accordance with Section 5-05.3(22) of the WSDOT Standard Specifications within the same time parameters stated above. d. Pavement restoration: Pavement restoration shall meet the following requirements for: Arterials: See Standard Plans 6-64 through 6-69. Non-Arterials: OCI >_ 75: See Standard Plans 6-64 through 6-69 and full width slurry seal or full width overlay with 1" of HMA Class 3/8" 75 > OCI >_ 55: See Standard Plans 6-64 through 6-69 and full width 2" HMA Class 1/2". OCI < 55: See Standard Plans 6-64 through 6-69. OCI is the overall condition index of the pavement. Please contact the City's Pavement Management Analyst at 253-856-5600 for the OCI of a particular Street. 3. Controlled Density Backfill: As an alternative to mechanical compaction, trench backfill above the bedding and below the base course or ATB may be accomplished by use of CDF in a design mixture according to Section 2-09.3(1)E of WSDOT Standard Specifications. The contractor shall provide a mix design in writing and the CDF shall not be placed until the Engineer has reviewed the mix design. CDF shall meet the requirements of Section 6-44 237 6-02.3(5)C of the WSDOT Standard Specifications and shall be accepted based on a Certificate of Compliance. The producer shall provide a Certificate of Compliance for each truckload of control density backfill. The Certificate of Compliance shall verify that the delivered material is in compliance with the mix design. Testing of CDF shall be in accordance with ASTM D4832. 6.17.0 Final Adjustment of Utility Facilities All utility system covers which are located on proposed asphalt streets, shall be temporarily placed at subgrade elevation prior to placing crushed surfacing material. Final adjustment of all covers and access entries shall be made following final paving as follows: 1. Saw-cutting or neat-line jack hammering of the pavement around lids and covers. Opening should not be larger than 12" beyond the radius of the cover. 2. Removing base material, surfacing course, and frame; adding raising bricks and grout; replacing frame and cover matching the finished Profile Grade of the surrounding pavement. 3. Filling and mechanically compacting around the structure and frame with crushed surfacing material or ATB, or placing in 5" minimum thickness of cement concrete Class 4000 to within 2" of the top. 4. Filling the remaining 2" with HMA compacted and sealed to provide a dense, uniform surface. 5. Final adjustment of all covers and access entries shall be completed within 30 days of final paving. 6.18 Final Cleanup In addition to restoration of the Street as described above, the responsible Developer shall care for adjacent areas in compliance with Sections 1-04.11 "Final Cleanup" and 8-01 "Roadside Seeding" in the WSDOT Standard Specifications. In particular: 6.18 A Streets Streets shall be cleaned and swept, both during and after the installation Work. The contractor shall remove any track-out material by the end of the work day, when the material causes a safety issue, or when required by the Engineer. 6.18 B Disturbed Soils Disturbed soils shall be Finished Graded, seeded and mulched after installation of utilities. In limited areas, seeding and mulching by hand, using approved methods, will be acceptable. 6-45 238 6.18 C Ditch Lines Ditch lines with soil susceptible to Erosion and subject to rapid flows may require seeding, matting, netting, check dams, or rock lining to control Erosion. 6.18 D Downstream Drainage Any silting of downstream drainage facilities, whether ditches or pipe and catch basins, which results from the construction activity shall be cleaned out and the Site restored to a stable condition as part of Site cleanup. 6.18 E Temporary Control Materials and Fencing Remove all temporary erosion and sediment control materials and fencing and dispose of properly, when authorized by the Engineer. 6.19 Roadway Design Standards Table 6.7 Arterial Roadways I Collector Roadways Local Roadways Design I Arterial Residential Industrial/ Parameter Principal Minor I _ Commercial Residential Private Industri Residential Street Street Streets al Standard Plan 1 6-2, 6-3 6-3 6-4 6-5 6-6 6-7 6-11, 6-12 6-15 Design Capacity 30,000 — 20,000 — <15,000 <5,000 <3,500 5,000 — <1,000 <90 ADT 50,000 30,000 10,000 (mph 2 Design Speed 35 — 60 35 — 45 30 — 35 30 — 35 30 — 35 30 — 35 30 25 Intersection 2600' 1300' 600' 600' 300' 300, 200' 200' Spacing Intersection Tangent3 150' 150' 100, 100, 100, 100, 50' 10, Gradient 9%4 12% 12% 12% 12% 12% 12% $ 15% 5 Maximum Gradient Minimum 0.30% 0.30% 0.30% 0.30% 0.30% 0.30% 0.30% 0.30% Curb Return Radius 35' 35' 35' 35' 25' 35' 25' Geometric Design WB-50 WB-50 I WB-62 BUS-40 BUS-40 WB-62 BUS-40 BUS-40 Vehicle Driveway Corner Clearance 7 300' 200' I 100, 100, 100, I 50' 20' 20'8,9 Dwy to Dwy Separation 10 300' 200' I 200' 200' 50' 100' 10' 10' 6-46 239 Table 6.8 Arterial and Collector Streets Design Values Design Speed (mph) Z 30 35 40 45 50 55 60 Min. horizontal curvature for 6% Stopping Sight 275 380 510 650 835 1,065 1,340 Distance, radius (ft) (max allowable on arterials) 11 1 F Stopping sight distance (ft) 200 250 305 360 425 495 570 Intersection/Driveway sight distance ft Right turn movement 12 290 335 385 430 480 530 575 Left-turn moveme nt (to cross 1 lane 335 390 445 500 555 610 665 Passing sight distance (ft) 1090 1280 1470 1625 1835 1985 2135 for 2 lane street Vertical Curve Length W sag (min) 15,16 37 49 64 79 96 115 136 W crest(min) 15 19 29 44 61 84 114 151 Table 6.9 Local Streets Design Values Design Speed (mph) Z 25 30 Min. horizontal curvature for normal crown section, radius (ft) 17,18 180 330 Stopping sight distance (ft) 155 200 Intersection/Driveway sight distance Right turn movement (ft) 9 240 290 Left-turn movement(to cross 1 lane) loll 280 335 6-47 240 Tables 6.7, 6.8 and 6.9 - Street Design Standards Summary -Footnotes 1. The horizontal widths may be increased to accommodate bio-swales, special mid- block or intersection geometric configurations, and bus turn-outs. 2. The Design Speed is equivalent to the posted speed plus five (5) miles per hour. 3. Distance is measured from the P.C.R. (Point of Curb Return) to the centerline P.C. (Point of Curvature) or P.T. (Point of Tangent). 4. The design maximum of 9% for streets classified as Principal Arterials is based upon criteria from the Washington State DOT. This design maximum may be exceeded for routes not anticipated to be reclassified as State Highways, or for which no practical/economic alternative exists. 5. Street gradients that exceed 12%, up to the design maximum of 15%, must be approved by the Fire Marshal. Approval may include the requirement that fire suppression sprinkler systems be installed in all residential structures that have their sole access from that street. 6. At the intersection of two dissimilarly classified streets, the larger curb return radius shall be used. Two-centered or three-centered curves should be used on oblique angle intersections, or in order to accommodate WB-62 or WB-50 vehicles. 7. Distance is measured from the near side of the driveway to the ultimate location of the P.C.R. of the adjacent intersecting street. City approval of driveways within this buffer zone may be contingent upon driveway geometrics that restrict turns to either right-in or right-out only. Reciprocal access agreements with the adjoining property owners may also be required as a condition of location approval. 8. Residential driveways shall be a minimum of 5' from the nearest edge to the property line. 9. On a case-by-case basis, cul-de-sacs may be allowed less than a 10' separation. 10. For parcels adjacent to a traffic signal, 300' shall be used unless a traffic study successfully demonstrates that the intersection area of influence is less than 300'. 11. The superelevation rate may be increased with the permission of the Engineer. Superelevation rates of 0.06 should not be exceeded on routes that are anticipated to have significant truck traffic in the travel stream, or on streets that are anticipated to have on-street parking permitted. Superelevation should not be used on local residential streets. 12. Entering Sight Distance shown is for a stopped passenger vehicle to turn right onto a two-lane roadway with grades of three percent or less. The time gap used in calculation of the right turn sight distance is 6.5 seconds. For other conditions the time gap must be adjusted and required sight distance re-calculated. (See AASHTO "A Policy on Geometric Design of Highways and Streets"). 13. Entering Sight Distance shown is for a stopped passenger vehicle to turn left onto a two-lane roadway with no median and grades of three percent or less. The time gap used in calculation of the left turn sight distance is 7.5 seconds. For other conditions the time gap must be adjusted and required sight distance re-calculated. (See AASHTO "A Policy on Geometric Design of Highways and Streets"). 6-48 241 14. For multi-lane roadways: For left turns onto a two-way roadways with more than two lanes, add 0.5 seconds for passenger cars and 0.7 seconds for trucks to the time gap for each additional lane from the left, in excess of one, to be crossed by the turning vehicle. 15. The length of vertical curve per percent change in the algebraic difference of the adjacent grades or "k" values are based on AASHTO's "A Policy on Geometric Design of Highways and Streets". 16. The AASHTO "comfort curve" for sag curve design, where the length of the sag curve is determined by the equation to the L =AxV2 right is an acceptable alternative if adequate supplemental street 46.5 illumination is provided. ("A" = the algebraic difference in roadway longitudinal gradients, "V" = Design Speed) 17. For residential streets with lower design speeds, this value may be reduced upon approval by the Engineer. Superelevation and upgraded street drainage may be used to reduce this minimum. 18. For "L" or 90 degree turns the centerline radius can be reduced to 55'. 19.

The purpose of the Street Tree Code is to provide information about how and where street trees are to be planted, and includes the list of currently approved Street Trees as determined by the Director of the Parks Department. The City of Kent Department of Public Works and the Parks Department jointly approve required Street Tree Plans associated with public street improvements. There are many site constraints that may limit the species of street trees that can be planted in a specific location.

Kent, WA 98032-5895 ENVIRONMENTAL REVIEW REPORT Decision Document DESIGN AND CONSTRUCTION STANDARDS UPDATE #ENV-2009-3/#RPSA-2090134 Responsible Official: Charlene Anderson, AICP I. PROPOSAL A. Description The City of Kent is considering adopting changes to its Design and Construction Standards (Standards). These are general conditions and requirements for all improvements or extensions of the City of Kent's street, storm drainage or utility systems. The Standards apply to all improvements made by public agencies, utility providers, and private developers. The City of Kent proposes to adopt these Design and Construction Standards for two primary reasons: 1. To the extent practicable, to set forth the minimum requirements for specific and consistent requirements for: construction of and improvements to public and private streets, water utilities, sewer utilities, and storm water utilities; the placement and operation of any utilities in rights of way; and all excavation and grading in the City. These Standards include procedures for inspection, acceptance, warranty, and deviations. 2. To establish uniform criteria to guide the City's own design, construction and improvement of City streets and utilities. These Standards are crafted to enable the City to achieve goals for neighborhood and transportation connectivity, transportation safety, affordable housing, storm water management, environmental protection, and cultural resource enhancement in balance with sound and efficient development. Decision Document Design and Construction Standards Update 412 #ENV-2009-3/#RPSA-2090134 With respect to transportation, the City requires consistent Standards to assure, so far as practical, that motoring, bicycling, transit, and pedestrian public safety needs are met in compliance with requirements for safety, convenience, aesthetics, surface water drainage, economical maintenance, and cultural and environmental resource protection. B.

BACKGROUND INFORMATION The City of Kent has adopted a revised Comprehensive Plan (Ordinance #3794 and 3797 - May 2006) which contains Planning Goals developed to be consistent with the State planning goals in the Growth Management Act, Countywide Planning Policies and the results of the Kent Community Forum and Visual Preference Survey. In part, these goals relate to Urban Growth, Transportation, Public Facilities, Urban Design and Economic Development. The various elements of Kent's Comprehensive Plan contain specific Goals and Policies that support the City's Planning Goals. These goals and policies represent an expression of community intentions and aspirations concerning the future of Kent and the area within the potential annexation area. The Comprehensive Plan is used by the Mayor, City Council, Land Use and Planning Board, Hearing Examiner and City departments to guide decision- making relative to development and capital facility spending. The proposed Standards are intended to implement, and be consistent with Kent's Comprehensive Plan, the Washington State Growth Management Act (GMA) and Kent's Concurrency Management (Chapter 12.11, Kent City Code). These Standards are being considered as an ordinance of the Kent City Council that will control the use and modification of the environment. As such, they are reviewed under SEPA as a non-project action. It is appropriate that the City consider likely impacts associated with the Standards and identify associated mitigation measures. Page 4 of 8 Decision Document Design and Construction Standards Update 415 #ENV-2009-3/#RPSA-2090134 Kent follows revisions to the Washington State Environmental Policy Act, Chapter 197-11 WAC (effective November 10, 1997), which implements ESHB 1724 and ESB 6094. III. ENVIRONMENTAL ELEMENTS A. Earth The City of Kent consists of varying topography including the Green River valley, with steep slopes on the east and west sides of the valley and rolling hills beyond. The Green River valley is partially filled by post-glacial alluvial deposits. Three main depositional units have been identified in the subsurface of the valley: younger alluvium, the Osceola mudflow, and older alluvium silty sand and gravel deposited by the Vashon stade glacier. The east and west hills are comprised of glacial till and other glacial deposits overlying bedrock of tertiary sedimentary rocks. Within the City there are areas of steep slopes and landslide hazard areas that have been identified. Slope stability will be reviewed during the environmental assessment of individual projects. Steep and hazardous slopes, as well as other environmentally sensitive areas are regulated under Kent City Code 11.06 Critical Areas, which was updated in 2006 via Kent City Council Ordinance 3805. These proposed Standards set the requirements and limitations for filling and grading, and include requirements for erosion control measures. The Standards are considered development regulations and specific impacts will be reviewed and addressed during the environmental assessment of individual projects. B. Air The proposed Standards include regulations for dust control associated with soil stockpiling and construction activities within the City of Kent. The proposed standards include by reference WSDOT Standard Specifications for Road, Bridge and Municipal Construction. Specifically, dust and erosion control is addressed in section 8-01 of this document, Erosion Control and Water Pollution Control. Project specific impacts to the air will be reviewed during the environmental assessment of individual projects. C. Water The proposed Standards include regulations that apply to construction activities, materials and methods both in and around Kent's surface and subsurface water resources. Regulations for controlling water runoff, both during and after construction activities are also included. Page 5 of 8 Decision Document Design and Construction Standards Update 416 #ENV-2009-3/#RPSA-2090134 Impacts associated with work in and around streams, wetlands, lakes and rivers are addressed by the provisions of Kent's critical areas code, Kent's Shoreline Master Program, and Kent's Surface Water Design Manual. Project specific impacts to water resources will be reviewed during the environmental assessment of individual projects. D. Plants A diversity of plant communities are located within the City of Kent in areas that may generally be described as forest, wetland, riparian, agricultural, and pasture. Also, landscape plantings on developed sites and along roadways are wide spread throughout Kent. The proposed Standards include requirements for landscaping within City right-of-way in areas such as medians, planter strips, and behind the sidewalks. The landscaping will consist of street trees and Type IV Landscaping as defined by KCC 15.07.050. Other adopted regulations related to mitigating impacts to plant communities include the Kent Zoning Code (KCC title 15), KCC 11.06 Critical Areas, and Kent's Shoreline Master Program. Project specific impacts to plant communities will be reviewed during the environmental assessment of individual projects. E. Animals While no specific City-wide inventory is available, all species of birds, mammals and fish common to the Puget Sound region are likely present in the City of Kent. The proposed Standards do not directly address habitat protection. Mitigation of impacts and protection of habitat from development are addressed in the Kent Zoning Code (KCC title 15), KCC 11.06 Critical Areas, Kent's Surface Water Design Manual and Kent's Shoreline Master Program. Project specific impacts to animals will be reviewed during the environmental assessment of individual projects. F. Energy and Natural Resources The proposed Standards apply to all development in the City. Petroleum products will be used in the new asphalt and pipe for utility systems and used by equipment during the construction of the improvements. Land area is also required to be dedicated to road and pedestrian ways, to accommodate grading limitations, and for utility easements. Electric energy will be used by new street lights and traffic signals. Page 6 of 8 Decision Document Design and Construction Standards Update 417 #ENV-2009-3/#RPSA-2090134 Project specific impacts to energy and natural resources will be reviewed during the environmental assessment of individual projects. G. Environmental Health The proposed Standards include specifications for construction materials, methods and maintenance of roadways and utility systems throughout the City. Noise impacts associated with work conducted under these standards are addressed by federal, state and local regulations, and apply to all development in the City. While no risks of exposure to toxic chemicals, risk related to fire and explosion, spill or hazardous waste are contemplated at this point, project specific impacts to environmental health will be reviewed during the environmental assessment of individual projects. H. Land and Shoreline Use Residential, commercial, industrial, agricultural and recreational parks are predominant land uses within the City. The City of Kent has five general categories of zoning districts that regulate land use: agricultural, single-family residential, multifamily residential, commercial and industrial. While the proposed Standards are intended to be consistent with the City's land use goals as expressed in the Comprehensive Plan, they relate specifically to materials, methods and maintenance associated with utility, roadway and grading work within the City. The Standards are crafted to enable the City to achieve goals for neighborhood and transportation connectivity, transportation safety, affordable housing, storm water management, environmental protection, and cultural resource enhancement in balance with sound and efficient development as expressed in the Comprehensive Plan. Compliance with the Standards will in many applications require the dedication of land to accommodate roadways, sidewalks, utility corridors and associated equipment. Land devoted to these uses is necessary to support public health, safety and welfare, and ensure that the growth and development of the City is orderly. The City contains seven shorelines of the state. Any proposed development within Shoreline jurisdiction is subject to the policies and regulations of the City's Shoreline Master Program. Additional regulations regarding land use within the City are found in Kent's Critical Areas Code, Surface Water Design Manual and Zoning Code.
