Bids must be delivered and received at the City Clerk's office by the above -stated time, regardless of delivery method, including U.S. Mail. All bids will be opened and read publicly aloud immediately following 11:00 a.m. for the City of Kent project named as follows: E Tacoma St. — Kensington Ave. Drainage Improvements Project Number: 18-3019 The City Clerk will read the bids out loud from the Clerk's office. Individuals can stand in the lobby outside the Clerk's office during the bid opening to hear the bid results. A mandatory pre -bid site visit is scheduled for Thursday February 24, 2022 at 9:00 a.m. at Mill Creek Canyon Earthworks Park (located to the east of the intersection of E Titus Street and Reiten Rd.). If you are unable to make this date but still wish to bid on this project, please contact Drew Holcomb at 253-856-5561. The purpose of this site visit is for interested contractors to get a sense of the project's location and its overall setting, which otherwise is not easily determined using Google Earth and is partially located on private property accessed through easements. City staff will be present only to provide access to the ditch; not to answer questions or provide information. If a follow-up question after the site visit requires further clarification, this information will be provided through an addendum. A sign -in sheet will be provided. Contractors must sign -in to confirm that they have visited the project site. Bids from the contractor will only be considered if they attend this mandatory pre - bid site visit. This project is not anticipated to begin construction until the dry season as this project consists of clearing and using rip rap to construct a trapezoidal drainage ditch in a forested ravine which is located on easements through private property and City right of way. Steep banks in the ravine will require the construction of gabion baskets walls and two gabion basket check dams. The existing ditch outlet will be filled and a new type 2 manhole will be set and storm pipe will connect to the existing manhole which will be raise to finished grade and filled in. Two quarry spall lined drainage swales will be constructed to drain Tacoma St. to the ditch inlet headwall.

THIS FORM INCLUDES CRITERIA ESTABLISHED BY STATE LAW THAT MUST BE MET TO BE CONSIDERED A RESPONSIBLE BIDDER AND QUALIFIED TO BE AWARDED THIS PUBLIC WORKS PROJECT AS WELL AS SUPPLEMENTAL CRITERIA ESTABLISHED BY THE CITY THAT ARE APPLICABLE TO THIS PUBLIC WORKS PROJECT. THE BIDDER SHOULD READ AND RESPOND TO THIS FORM CAREFULLY. Indicia of contractor's responsibility inherently involve subjective determinations as to the contractor's ability to perform and complete the contract work responsibly and to the owner city's satisfaction. The city has an obligation and a duty to its citizens and its taxpayers to administer its budgets and complete its projects in a businesslike manner. Accordingly, it has a duty to exercise the type of inquiry and discretion a business would conduct when selecting a contractor who will be responsible to perform the contract work. The city's supplemental criteria are based, in large part, on the qualification statement form used by the American Institute of Architects. The city provides these criteria so as to provide the most objective framework possible within which the city will make its decision regarding the bidder's ability to be responsible to perform the contract work. These criteria, taken together, will form the basis for the city's decision that a bidder is or is not responsible to perform the contract work. Any bidder may make a formal written request to the city to modify the criteria set forth in this qualification statement, but that request may only be made within 48 hours of the date and time that the bidder first obtains the bid documents or three (3) business days prior to the scheduled bid opening date, whichever occurs first. If the city receives a modification request, it will consider any information submitted in the request and will respond before the bid submittal deadline. If the city's evaluation results in changed criteria, the city will issue an addendum establishing the new or modified criteria. If the city determines that, based on the criteria established in this statement, a bidder is not responsible to perform the contract work, the city will provide written notice of its determination that will include the city's reason for its decision. The bidder has 24 hours from the time the city delivers written notice to the bidder that the bidder is not responsible to perform the contract work to appeal the city's determination. No appeals will be received after the expiration of this 24 hour appeal period. The city may deliver this notice by hand delivery, email, facsimile, or regular mail. In the event the city uses regular mail, the delivery will be deemed complete three days after being placed in the U.S. Mail. The bidder's right to appeal is limited to the single remedy of providing the city with additional information to be considered before the city issues a final determination. Bidder acknowledges and understands that, as provided by RCW 39.04.350, no other appeal is allowed and no other remedy of any kind or nature is available to the bidding contractor if the City determines that the bidder is not responsible to perform the contract work. Kensington Drainage Improvements/Holcomb 14 February 14, 2022 Project Number: 18-3019 If the bidder fails to request a modification within the time allowed, or fails to appeal a determination that the bidder is not responsible within the time allowed, the city will make its determination of bidder responsibility based on the information submitted. COMPLETE AND SIGN THIS FORM AS PART OF YOUR BID. FAILURE TO PROPERLY COMPLETE THIS FORM MAY ALSO RESULT IN A DETERMINATION THAT YOUR BID IS NON -RESPONSIVE AND THEREFORE VOID.

In that event, this insurance will be primary relative to insurance policy(s) which designates the additional insured as a Named Insured and we will not require contribution from such insurance if the written contract also requires that this insurance be non-contributory.

(If superelevations require intermediate stakes along vertical curves, the City will provide staking at closer intervals.) One set of primary cut and fill stakes will be set for site work. One set of secondary final grade cut and fill stakes will be set where deemed applicable as determined by the Engineer. 3. Storm Sewers - Two cut or fill stakes for each inlet, catch basin or manhole will be set at appropriate offsets to the center of the structure. After installation and backfill, inverts will be checked for correctness. 4. Sanitary Sewers - Two cut or fill stakes for each manhole or cleanout location will be set at appropriate offsets to the center of the structure. After installation and backfill, inverts will be checked for correctness. 5. Water Main - One set of line stakes will be furnished for water mains at 50-foot stations. Additionally, two reference stakes for each valve, hydrant, tee and angle point location will be set concurrently with these line stakes. 6. Staking for Embankments - Catch points and one line stake will be set in those cases where the vertical difference in elevation from the construction centerline to the toe or top of a cut or fill slope exceeds 3 feet. In all other areas, stakes shall be set at an appropriate offset to the street centerline to allow for the preservation of said offsets through the rough grading phase. In both cases the stakes shall be clearly marked with appropriate information necessary to complete the rough grading phase. 7. Curb and Gutters - One set of curb and gutter stakes shall be set at an appropriate offset at 25-foot intervals, beginning and end points of curves and curb returns, wheelchair ramps, driveways, and sufficient mid-curve points to establish proper alignment. 8.

Kensington Drainage Improvements/Holcomb 1 - 27 February 14, 2022 Project Number: 18-3019 SECTION 1-08.5 IS REVISED BY DELETING THE THIRD PARAGRAPH AND REPLACING WITH THE FOLLOWING: 1-08.5 Time for Completion Contract time shall begin on the day of the Notice to Proceed. The Contract Provisions may specify another starting date for Contract time, in which case, time will begin on the starting date specified. SECTION 1-08.6 IS REVISED BY DELETING THE FIFTH, SIXTH, AND SEVENTH PARAGRAPHS AND REPLACING WITH THE FOLLOWING: 1-08.6 Suspension of Work If the performance of all or any part of the Work is suspended for an unreasonable period of time by an act of the Contracting Agency in the administration of the Contract, or by failure to act within the time specified in the Contract (or if no time is specified, within a reasonable time), the Engineer will make an adjustment for any increase in the cost or time for the performance of the Contract (excluding profit) necessarily caused by the suspension. However, no adjustment will be made for any suspension if (1) the performance would have been suspended by any other cause, including the fault or negligence of the Contractor, or (2) an equitable adjustment is provided for or excluded under any other provision of the Contract. If the Contactor believes that the performance of the Work is suspended for an unreasonable period of time and such suspension is the responsibility of the Contracting Agency, the Contractor shall immediately submit a written notice of protest to the Engineer as provided in Section 1-04.5. No adjustment shall be allowed for any costs incurred more than 10 calendar days before the date the Engineer receives the Contractors written notice to protest. In any event, no protest will be allowed later than the date of the Contractors signature on the Final Pay Estimate. The Contractor shall keep full and complete records of the costs and additional time of such suspension, and shall permit the Engineer to have access to those records and any other records as may be deemed necessary by the Engineer to assist in evaluating the protest. The Engineer will determine if an equitable adjustment in cost or time is due as provided in this Section.

SECTION 1-08.7 MAINTENANCE DURING SUSPENSION IS REVISED BY DELETING THE FOURTH AND SIXTH PARAGRAPHS. SECTION 1-08.9 IS DELETED AND REPLACED WITH THE FOLLOWING: 1-08.9 Notice to Proceed, Prosecution and Hours of Work Kensington Drainage Improvements/Holcomb 1 - 28 February 14, 2022 Project Number: 18-3019 Time is of the essence of the Contract. Delays inconvenience the traveling public, obstruct traffic, interfere with and delay commerce, and increase risk to Highway users. Delays also cost tax payers undue sums of money, adding time needed for administration, engineering, inspection, and supervision. Because the Contracting Agency finds it impractical to calculate the actual cost of delays, it has adopted the following formula to calculate liquidated damages for failure to complete the physical Work of a Contract on time. Accordingly, the Contractor agrees: 1. To pay (according to the following formula) liquidated damages for each working day beyond the number of working days established for Physical Completion, and 2. To authorize the Engineer to deduct these liquidated damages from any money due or coming due to the Contractor. Liquidated Damages Formula LD = 0.15*C / T Where: LD = liquidated damages per working day (rounded to the nearest dollar) C = original Contract amount T = original time for Physical Completion When the Contract Work has progressed to the extent that the Contracting Agency has full use and benefit of the facilities, both from the operational and safety standpoint, all the initial plantings are completed and only minor incidental Work, replacement of temporary substitute facilities, plant establishment periods, or correction or repair remains to physically complete the total Contract, the Engineer may determine the Contract Work is substantially complete. The Engineer will notify the Contractor in writing of the Substantial Completion Date. For overruns in Contract time occurring after the date so established, the formula for liquidated damages shown above will not apply. For overruns in Contract time occurring after the Substantial Completion Date, liquidated damages shall be assessed on the basis of direct engineering and related costs assignable to the project until the actual Physical Completion Date of all the Contract Work. The Contractor shall complete the remaining Work as promptly as possible. Upon request by the Engineer, the Contractor shall furnish a written schedule for completing the physical Work on the Contract. Liquidated damages will not be assessed for any days for which an extension of time is granted. No deduction or payment of liquidated damages will, in any degree, release the Contractor from further obligations and liabilities to complete the entire Contract.

These values will also be the Upper Specification Limit (USL) and Lower Specification Limit (LSL) required in Section 1-06.2(2)D2 Kensington Drainage Improvements/Holcomb 5 - 15 February 14, 2022 Project Number: 18-3019 Property Non-Statistical Evaluation Commercial Evaluation Asphalt Binder +/- 0.5% +/- 0.7% Air Voids, Va 2.5% min. and 5.5% max N/A For Aggregates in the mixture: a. First, determine preliminary upper and lower acceptance limits by applying the following tolerances to the approved JMF. Aggregate Percent Passing Non-Statistical Evaluation Commercial Evaluation 1, ¾, ½, and 3/8 sieves +/- 6% +/- 8% No. 4 sieve +/-6% +/- 8% No. 8 Sieve +/- 6% +/-8% No. 200 sieve +/- 2.0% +/- 3.0% b. Second, adjust the preliminary upper and lower acceptance limits determined from step (a) the minimum amount necessary so that none of the aggregate properties are outside the control points in Section 9-03.8(6). The resulting values will be the upper and lower acceptance limits for aggregates, as well as the USL and LSL required in Section 1-06.2(2)D2. 2. Job Mix Formula Adjustments An adjustment to the aggregate gradation or asphalt binder content of the JMF requires approval of the Engineer. Adjustments to the JMF will only be considered if the change produces material of equal or better quality and may require the development of a new mix design if the adjustment exceeds the amounts listed below. a. Aggregates 2 percent for the aggregate passing the 1½, 1 , ¾, ½, , and the No. 4 sieves, 1 percent for aggregate passing the No. 8 sieve, and 0.5 percent for the aggregate passing the No. 200 sieve. The adjusted JMF shall be within the range of the control points in Section 9-03.8(6). b. Asphalt Binder Content The Engineer may order or approve changes to asphalt binder content. The maximum adjustment from the approved mix design for the asphalt binder content shall be 0.3 percent 5-04.3(9)A Vacant 5-04.3(9)B Vacant 5-04.3(9)C Mixture Acceptance – Nonstatistical Evaluation HMA mixture which is accepted by Nonstatistical Evaluation will be evaluated by the Contracting Agency by dividing the HMA tonnage into lots. Kensington Drainage Improvements/Holcomb 5 - 16 February 14, 2022 Project Number: 18-3019 5-04.3(9)C1 Mixture Nonstatistical Evaluation – Lots and Sublots A lot is represented by randomly selected samples of the same mix design that will be tested for acceptance. A lot is defined as the total quantity of material or work produced for each Job Mix Formula placed. Only one lot per JMF is expected. A sublot shall be equal to one days production or 800 tons, whichever is less except that the final sublot will be a minimum of 400 tons and may be increased to 1200 tons. All of the test results obtained from the acceptance samples from a given lot shall be evaluated collectively. If the Contractor requests a change to the JMF that is approved, the material produced after the change will be evaluated on the basis of the new JMF for the remaining sublots in the current lot and for acceptance of subsequent lots. For a lot in progress with a CPF less than 0.75, a new lot will begin at the Contractors request after the Engineer is satisfied that material conforming to the Specifications can be produced. Sampling and testing for evaluation shall be performed on the frequency of one sample per sublot. 5-04.3(9)C2 Mixture Nonstatistical Evaluation Sampling Samples for acceptance testing shall be obtained by the Contractor when ordered by the Engineer. The Contractor shall sample the HMA mixture in the presence of the Engineer and in accordance with AASHTO T 168. A minimum of three samples should be taken for each class of HMA placed on a project. If used in a structural application, at least one of the three samples shall to be tested. Sampling and testing HMA in a Structural application where quantities are less than 400 tons is at the discretion of the Engineer. For HMA used in a structural application and with a total project quantity less than 800 tons but more than 400 tons, a minimum of one acceptance test shall be performed. In all cases, a minimum of 3 samples will be obtained at the point of acceptance, a minimum of one of the three samples will be tested for conformance to the JMF: If the test results are found to be within specification requirements, additional testing will be at the Engineers discretion. If test results are found not to be within specification requirements, additional testing of the remaining samples to determine a Composite Pay Factor (CPF) shall be performed. 5-04.3(9)C3 Mixture Nonstatistical Evaluation – Acceptance Testing Testing of HMA for compliance of Va will be at the option of the Contracting Agency. If tested, compliance of Va will use WSDOT SOP 731. Kensington Drainage Improvements/Holcomb 5 - 17 February 14, 2022 Project Number: 18-3019 Testing for compliance of asphalt binder content will be by WSDOT FOP for AASHTO T 308. Testing for compliance of gradation will be by FOP for WAQTC T 27/T 11. 5-04.3(9)C4 Mixture Nonstatistical Evaluation – Pay Factors For each lot of material falling outside the tolerance limits in 5-04.3(9), the Contracting Agency will determine a Composite Pay Factor (CPF) using the following price adjustment factors: Table of Price Adjustment Factors Constituent Factor “f” All aggregate passing: 1½, 1 , ¾, ½, and No.4 sieves 2 All aggregate passing No. 8 sieve 15 All aggregate passing No. 200 sieve 20 Asphalt binder 40 Air Voids (Va) (where applicable) 20 Each lot of HMA produced under Nonstatistical Evaluation and having all constituents falling within the tolerance limits of the job mix formula shall be accepted at the unit Contract price with no further evaluation. When one or more constituents fall outside the nonstatistical tolerance limits in the Job Mix Formula shown in Table of Price Adjustment Factors, the lot shall be evaluated in accordance with Section 1-06.2 to determine the appropriate CPF. The nonstatistical tolerance limits will be used in the calculation of the CPF and the maximum CPF shall be 1.00. When less than three sublots exist, backup samples of the existing sublots or samples from the Roadway shall be tested to provide a minimum of three sets of results for evaluation. 5-04.3(9)C5 Vacant 5-04.3(9)C6 Mixture Nonstatistical Evaluation – Price Adjustments For each lot of HMA mix produced under Nonstatistical Evaluation when the calculated CPF is less than 1.00, a Nonconforming Mix Factor (NCMF) will be determined. The NCMF equals the algebraic difference of CPF minus 1.00 multiplied by 60 percent. The total job mix compliance price adjustment will be calculated as the product of the NCMF, the quantity of HMA in the lot in tons, and the unit Contract price per ton of mix. If a constituent is not measured in accordance with these Specifications, itsindividual pay factor will be considered 1.00 in calculating the Composite PayFactor(CPF). Kensington Drainage Improvements/Holcomb 5 - 18 February 14, 2022 Project Number: 18-3019 5-04.3(9)C7 Mixture Nonstatistical Evaluation - Retests The Contractor may request a sublot be retested. To request a retest, the Contractor shall submit a written request within 7 calendar days after the specific test results have been received. A split of the original acceptance sample will be retested. The split of the sample will not be tested with the same tester that ran the original acceptance test. The sample will be tested for a complete gradation analysis, asphalt binder content, and, at the option of the agency, Va. The results of the retest will be used for the acceptance of the HMA in place of the original sublot sample test results. The cost of testing will be deducted from any monies due or that may come due the Contractor under the Contract at the rate of $500 per sample. 5-04.3 (9)D Mixture Acceptance – Commercial Evaluation If sampled and tested, HMA produced under Commercial Evaluation and having all constituents falling within the tolerance limits of the job mix formula shall be accepted at the unit Contract price with no further evaluation. When one or more constituents fall outside the commercial tolerance limits in the Job Mix Formula shown in 5-04.3(9), the lot shall be evaluated in accordance with Section 1-06.2 to determine the appropriate CPF. The commercial tolerance limits will be used in the calculation of the CPF and the maximum CPF shall be 1.00. When less than three sublots exist, backup samples of the existing sublots or samples from the street shall be tested to provide a minimum of three sets of results for evaluation. For each lot of HMA mix produced and tested under Commercial Evaluation when the calculated CPF is less than 1.00, a Nonconforming Mix Factor (NCMF) will be determined. The NCMF equals the algebraic difference of CPF minus 1.00 multiplied by 60 percent. The Job Mix Compliance Price Adjustment will be calculated as the product of the NCMF, the quantity of HMA in the lot in tons, and the unit Contract price per ton of mix. If a constituent is not measured in accordance with these Specifications, itsindividual pay factor will be considered 1.00 in calculating the Composite PayFactor(CPF). 5-04.3(10) HMA Compaction Acceptance HMA mixture accepted by nonstatistical evaluation that is used in traffic lanes, including lanes for intersections, ramps, truck climbing, weaving, and speed change, and having a specified compacted course thickness greater than 0.10-foot, shall be compacted to a specified level of relative density. The specified level of relative density shall be a Composite Pay Factor (CPF) of not less than 0.75 when evaluated in accordance with Section 1-06.2, using a LSL of 92.0 (minimum of 92 percent of the maximum density). The maximum density shall be determined by WSDOT FOP for AASHTO T 729. The specified level of density attained will be determined by the evaluation of the density of the pavement. The density of the pavement shall be determined in Kensington Drainage Improvements/Holcomb 5 - 19 February 14, 2022 Project Number: 18-3019 accordance with WSDOT FOP for WAQTC TM 8, except that gauge correlation will be at the discretion of the Engineer, when using the nuclear density gauge and WSDOT SOP 736 when using cores to determine density. Tests for the determination of the pavement density will be taken in accordance with the required procedures for measurement by a nuclear density gauge or roadway cores after completion of the finish rolling. If the Contracting Agency uses a nuclear density gauge to determine density the test procedures FOP for WAQTC TM 8 and WSDOT SOP T 729 will be used on the day the mix is placed and prior to opening to traffic. Roadway cores for density may be obtained by either the Contracting Agency or the Contractor in accordance with WSDOT SOP 734. The core diameter shall be 4-inches minimum, unless otherwise approved by the Engineer. Roadway cores will be tested by the Contracting Agency in accordance with WSDOT FOP for AASHTO T 166. If the Contract includes the Bid item Roadway Core the cores shall be obtained by the Contractor in the presence of the Engineer on the same day the mix is placed and at locations designated by the Engineer. If the Contract does not include the Bid item Roadway Core the Contracting Agency may obtain the cores. For a lot in progress with a CPF less than 0.75, a new lot will begin at the Contractors request after the Engineer is satisfied that material conforming to the Specifications can be produced. HMA mixture accepted by commercial evaluation and HMA constructed under conditions other than those listed above shall be compacted on the basis of a test point evaluation of the compaction train. The test point evaluation shall be performed in accordance with instructions from the Engineer. The number of passes with an approved compaction train, required to attain the maximum test point density, shall be used on all subsequent paving. HMA for preleveling shall be thoroughly compacted. HMA that is used for preleveling wheel rutting shall be compacted with a pneumatic tire roller unless otherwise approved by the Engineer. Test Results For a sublot that has been tested with a nuclear density gauge that did not meet the minimum of 92 percent of the reference maximum density in a compaction lot with a CPF below 1.00 and thus subject to a price reduction or rejection, the Contractor may request that a core be used for determination of the relative density of the sublot. The relative density of the core will replace the relative density determined by the nuclear density gauge for the sublot and will be used for calculation of the CPF and acceptance of HMA compaction lot. Kensington Drainage Improvements/Holcomb 5 - 20 February 14, 2022 Project Number: 18-3019 When cores are taken by the Contracting Agency at the request of the Contractor, they shall be requested by noon of the next workday after the test results for the sublot have been provided or made available to the Contractor. Core locations shall be outside of wheel paths and as determined by the Engineer. Traffic control shall be provided by the Contractor as requested by the Engineer. Failure by the Contractor to provide the requested traffic control will result in forfeiture of the request for cores. When the CPF for the lot based on the results of the HMA cores is less than 1.00, the cost for the coring will be deducted from any monies due or that may become due the Contractor under the Contract at the rate of $200 per core and the Contractor shall pay for the cost of the traffic control. 5-04.3(10)A HMA Compaction – General Compaction Requirements Compaction shall take place when the mixture is in the proper condition so that no undue displacement, cracking, or shoving occurs. Areas inaccessible to large compaction equipment shall be compacted by other mechanical means. Any HMA that becomes loose, broken, contaminated, shows an excess or deficiency of asphalt, or is in any way defective, shall be removed and replaced with new hot mix that shall be immediately compacted to conform to the surrounding area. The type of rollers to be used and their relative position in the compaction sequence shall generally be the Contractors option, provided the specified densities are attained. Unless the Engineer has approved otherwise, rollers shall only be operated in the static mode when the internal temperature of the mix is less than 175°F. Regardless of mix temperature, a roller shall not be operated in a mode that results in checking or cracking of the mat. Rollers shall only be operated in static mode on bridge decks. 5-04.3(10)B HMA Compaction – Cyclic Density Low cyclic density areas are defined as spots or streaks in the pavement that are less than 90 percent of the theoretical maximum density. At the Engineers discretion, the Engineer may evaluate the HMA pavement for low cyclic density, and when doing so will follow WSDOT SOP 733. A $500 Cyclic Density Price Adjustment will be assessed for any 500-foot section with two or more density readings below 90 percent of the theoretical maximum density. 5-04.3(10)C Vacant 5-04.3(10)D HMA Nonstatistical Compaction 5-04.3(10)D1 HMA Nonstatistical Compaction – Lots and Sublots HMA compaction which is accepted by nonstatistical evaluation will be based on acceptance testing performed by the Contracting Agency dividing the project into compaction lots. Kensington Drainage Improvements/Holcomb 5 - 21 February 14, 2022 Project Number: 18-3019 A lot is represented by randomly selected samples of the same mix design that will be tested for acceptance. A lot is defined as the total quantity of material or work produced for each Job Mix Formula placed. Only one lot per JMF is expected. A sublot shall be equal to one days production or 400 tons, whichever is less except that the final sublot will be a minimum of 200 tons and may be increased to 800 tons. Testing for compaction will be at the rate of 5 tests per sublot per WSDOT T 738. The sublot locations within each density lot will be determined by the Engineer. For a lot in progress with a CPF less than 0.75, a new lot will begin at the Contractors request after the Engineer is satisfied that material conforming to the Specifications can be produced. HMA mixture accepted by commercial evaluation and HMA constructed under conditions other than those listed above shall be compacted on the basis of a test point evaluation of the compaction train. The test point evaluation shall be performed in accordance with instructions from the Engineer. The number of passes with an approved compaction train, required to attain the maximum test point density, shall be used on all subsequent paving. HMA for preleveling shall be thoroughly compacted. HMA that is used to prelevel wheel ruts shall be compacted with a pneumatic tire roller unless otherwise approved by the Engineer. 5-04.3(10)D2 HMA Compaction Nonstatistical Evaluation – Acceptance Testing The location of the HMA compaction acceptance tests will be randomly selected by the Engineer from within each sublot, with one test per sublot. 5-04.3(10)D3 HMA Nonstatistical Compaction – Price Adjustments For each compaction lot with one or two sublots, having all sublots attain a relative density that is 92 percent of the reference maximum density the HMA shall be accepted at the unit Contract price with no further evaluation. When a sublot does not attain a relative density that is 92 percent of the reference maximum density, the lot shall be evaluated in accordance with Section 1-06.2 to determine the appropriate CPF. The maximum CPF shall be 1.00, however, lots with a calculated CPF in excess of 1.00 will be used to offset lots with CPF values below 1.00 but greater than 0.90. Lots with CPF lower than 0.90 will be evaluated for compliance per 5-04.3(11). Additional testing by either a nuclear moisture-density gauge or cores will be completed as required to provide a minimum of three tests for evaluation. For compaction below the required 92% a Non-Conforming Compaction Factor (NCCF) will be determined. The NCCF equals the algebraic difference of CPF minus 1.00 multiplied by 40 percent. The Compaction Price Adjustment will be calculated as the product of CPF, the quantity Kensington Drainage Improvements/Holcomb 5 - 22 February 14, 2022 Project Number: 18-3019 of HMA in the compaction control lot intons, and the unit Contract price per ton of mix. 5-04.3(11) Reject Work 5-04.3(11)A Reject Work General Work that is defective or does not conform to Contract requirements shall be rejected. The Contractor may propose, in writing, alternatives to removal and replacement of rejected material. Acceptability of such alternative proposals will be determined at the sole discretion of the Engineer. HMA that has been rejected is subject to the requirements in Section 1-06.2(2) and this specification, and the Contractor shall submit a corrective action proposal to the Engineer for approval. 5-04.3(11)B Rejection by Contractor The Contractor may, prior to sampling, elect to remove any defective material and replace it with new material. Any such new material will be sampled, tested, and evaluated for acceptance. 5-04.3(11)C Rejection Without Testing (Mixture or Compaction) The Engineer may, without sampling, reject any batch, load, or section of Roadway that appears defective. Material rejected before placement shall not be incorporated into the pavement. Any rejected section of Roadway shall be removed. No payment will be made for the rejected materials or the removal of the materials unless the Contractor requests that the rejected material be tested. If the Contractor elects to have the rejected material tested, a minimum of three representative samples will be obtained and tested. Acceptance of rejected material will be based on conformance with the nonstatistical acceptance Specification. If the CPF for the rejected material is less than 0.75, no payment will be made for the rejected material; in addition, the cost of sampling and testing shall be borne by the Contractor. If the CPF is greater than or equal to 0.75, the cost of sampling and testing will be borne by the Contracting Agency. If the material is rejected before placement and the CPF is greater than or equal to 0.75, compensation for the rejected material will be at a CPF of 0.75. If rejection occurs after placement and the CPF is greater than or equal to 0.75, compensation for the rejected material will be at the calculated CPF with an addition of 25 percent of the unit Contract price added for the cost of removal and disposal. 5-04.3(11)D Rejection - A Partial Sublot In addition to the random acceptance sampling and testing, the Engineer may also isolate from a normal sublot any material that is suspected of being defective in relative density, gradation or asphalt binder content. Such isolated material will not include an original sample location. A minimum of three random samples of the suspect material will be obtained and tested. The material will then be Kensington Drainage Improvements/Holcomb 5 - 23 February 14, 2022 Project Number: 18-3019 statistically evaluated as an independent lot in accordance with Section 1-06.2(2). 5-04.3(11)E Rejection - An Entire Sublot An entire sublot that is suspected of being defective may be rejected. When a sublot is rejected a minimum of two additional random samples from this sublot will be obtained. These additional samples and the original sublot will be evaluated as an independent lot in accordance with Section 1-06.2(2). 5-04.3(11)F Rejection - A Lot in Progress The Contractor shall shut down operations and shall not resume HMA placement until such time as the Engineer is satisfied that material conforming to the Specifications can be produced: 1. When the Composite Pay Factor (CPF) of a lot in progress drops below 1.00 and the Contractor is taking no corrective action, or 2. When the Pay Factor (PF) for any constituent of a lot in progress drops below 0.95 and the Contractor is taking no corrective action, or 3. When either the PFi for any constituent or the CPF of a lot in progress is less than 0.75. 5-04.3(11)G Rejection - An Entire Lot (Mixture or Compaction) An entire lot with a CPF of less than 0.75 will be rejected. 5-04.3(12) Joints 5-04.3(12)A HMA Joints 5-04.3(12)A1 Transverse Joints The Contractor shall conduct operations such that the placing of the top or wearing course is a continuous operation or as close to continuous as possible. Unscheduled transverse joints will be allowed and the roller may pass over the unprotected end of the freshly laid mixture only when the placement of the course must be discontinued for such a length of time that the mixture will cool below compaction temperature. When the Work is resumed, the previously compacted mixture shall be cut back to produce a slightly beveled edge for the full thickness of the course. A temporary wedge of HMA constructed on a 20H:1V shall be constructed where a transverse joint as a result of paving or planing is open to traffic. The HMA in the temporary wedge shall be separated from the permanent HMA by strips of heavy wrapping paper or other methods approved by the Engineer. The wrapping paper shall be removed and the joint trimmed to a slightly beveled edge for the full thickness of the course prior to resumption of paving. Kensington Drainage Improvements/Holcomb 5 - 24 February 14, 2022 Project Number: 18-3019 The material that is cut away shall be wasted and new mix shall be laid against the cut. Rollers or tamping irons shall be used to seal the joint. 5-04.3(12)A2 Longitudinal Joints The longitudinal joint in any one course shall be offset from the course immediately below by not more than 6 inches nor less than 2 inches. All longitudinal joints constructed in the wearing course shall be located at a lane line or an edge line of the Traveled Way.

The notched wedge joint shall have a vertical edge of not less than the maximum aggregate size or more than ½ of the compacted lift thickness and then taper down on a slope not steeper than 4H:1V. The sloped portion of the HMA notched wedge joint shall be uniformly compacted. 5-04.3(12)B Bridge Paving Joint Seals 5-04.3(12)B1 HMA Sawcut and Seal Prior to placing HMA on the bridge deck, establish sawcut alignment points at both ends of the bridge paving joint seals to be placed at the bridge ends, and at interior joints within the bridge deck when and where shown in the Plans. Establish the sawcut alignment points in a manner that they remain functional for use in aligning the sawcut after placing the overlay. Submit a Type 1 Working Drawing consisting of the sealant manufacturers application procedure. Construct the bridge paving joint seal as specified on the Plans and in accordance with the detail shown in the Standard Plans. Construct the sawcut in accordance with the detail shown in the Standard Plan. Construct the sawcut in accordance with Section 5-05.3(8)B and the manufacturers application procedure. 5-04.3(12)B2 Paved Panel Joint Seal Construct the paved panel joint seal in accordance with the requirements specified in Section 5-04.3(12)B1 and the following requirement: Clean and seal the existing joint between concrete panels in accordance with Section 5-01.3(8) and the details shown in the Standard Plans. 5-04.3(13) Surface Smoothness The completed surface of all courses shall be of uniform texture, smooth, uniform as to crown and grade, and free from defects of all kinds. The completed surface of the wearing course shall not vary more than inch from the lower edge of a 10-foot straightedge placed on the surface parallel to the centerline.

When deviations in excess of the above tolerances are found that result from ahigh place in the HMA, the pavement surface shall be corrected by one of the followingmethods: 1. Removal of material from high places by grinding with an approved grinding machine, or 2. Removal and replacement of the wearing course of HMA, or 3. By other method approved by the Engineer. Correction of defects shall be carried out until there are no deviations anywhere greater than the allowable tolerances. Deviations in excess of the above tolerances that result from a low place in the HMA and deviations resulting from a high place where corrective action, in the opinion of the Engineer, will not produce satisfactory results will be accepted with a price adjustment. The Engineer shall deduct from monies due or that may become dueto the Contractor the sum of $500.00 for each and every section of single traffic lane100 feet in length in which any excessive deviations described above are found. When utility appurtenances such as manhole covers and valve boxes are located in the traveled way, the utility appurtenances shall be adjusted to the finished grade prior to paving. This requirement may be waived when requested by the Contractor, at the discretion of the Engineer or when the adjustment details provided in the project plan or specifications call for utility appurtenance adjustments after the completion of paving. Utility appurtenance adjustment discussions will be included in the Pre- Paving planning (5-04.3(14)B3). Submit a written request to waive this requirement to the Engineer prior to the start of paving. 5-04.3(14) Planing (Milling) Bituminous Pavement The planing plan must be approved by the Engineer and a pre planing meeting must be held prior to the start of any planing. See Section 5-04.3(14)B2 for information on planing submittals. Planing operations shall be performed no more than 7 calendar days ahead of the time the planed area is to be paved, unless otherwise allowed by the Engineer in writing. Locations of existing surfacing to be planed are as shown in the Drawings. Where planing an existing pavement is specified in the Contract, the Contractor must remove existing surfacing material and to reshape the surface to remove irregularities. The finished product must be a prepared surface acceptable for receiving an HMA overlay. Kensington Drainage Improvements/Holcomb 5 - 26 February 14, 2022 Project Number: 18-3019 Use the cold milling method for planing unless otherwise specified in the Contract. Do not use the planer on the final wearing course of new HMA. Conduct planing operations in a manner that does not tear, break, burn, or otherwise damage the surface which is to remain. The finished planed surface must be slightly grooved or roughened and must be free from gouges, deep grooves, ridges, or other imperfections. The Contractor must repair any damage to the surface by the Contractors planing equipment, using an Engineer approved method. Repair or replace any metal castings and other surface improvements damaged by planing, as determined by the Engineer. A tapered wedge cut must be planed longitudinally along curb lines sufficient to provide a minimum of 4 inches of curb reveal after placement and compaction of the final wearing course. The dimensions of the wedge must be as shown on the Drawings or as specified by the Engineer. A tapered wedge cut must also be made at transitions to adjoining pavement surfaces (meet lines) where butt joints are shown on the Drawings. Cut butt joints in a straight line with vertical faces 2 inches or more in height, producing a smooth transition to the existing adjoining pavement. After planing is complete, planed surfaces must be swept, cleaned, and if required by the Contract, patched and preleveled. The Engineer may direct additional depth planing. Before performing this additional depth planing, the Contractor must conduct a hidden metal in pavement detection survey as specified in Section 5-04.3(14)A. 5-04.3(14)A Pre-Planing Metal Detection Check Before starting planing of pavements, and before any additional depth planing required by the Engineer, the Contractor must conduct a physical survey of existing pavement to be planed with equipment that can identify hidden metal objects. Should such metal be identified, promptly notify the Engineer. See Section 1-07.16(1) regarding the protection of survey monumentation that may be hidden in pavement. The Contractor is solely responsible for any damage to equipment resulting from the Contractors failure to conduct a pre-planing metal detection survey, or from the Contractors failure to notify the Engineer of any hidden metal that is detected. 5-04.3(14)B Paving and Planing Under Traffic Kensington Drainage Improvements/Holcomb 5 - 27 February 14, 2022 Project Number: 18-3019 5-04.3(14)B1 General In addition the requirements of Section 1-07.23 and the traffic controls required in Section 1-10, and unless the Contract specifies otherwise or the Engineer approves, the Contractor must comply with the following: 1. Intersections: a. Keep intersections open to traffic at all times, except when paving or planing operations through an intersection requires closure. Such closure must be kept to the minimum time required to place and compact the HMA mixture, or plane as appropriate. For paving, schedule such closure to individual lanes or portions thereof that allows the traffic volumes and schedule of traffic volumes required in the approved traffic control plan. Schedule work so that adjacent intersections are not impacted at the same time and comply with the traffic control restrictions required by the Traffic Engineer. Each individual intersection closure or partial closure, must be addressed in the traffic control plan, which must be submitted to and accepted by the Engineer, see Section 1-10.2(2). b. When planing or paving and related construction must occur in an intersection, consider scheduling and sequencing such work into quarters of the intersection, or half or more of an intersection with side street detours. Be prepared to sequence the work to individual lanes or portions thereof. c. Should closure of the intersection in its entirety be necessary, and no trolley service is impacted, keep such closure to the minimum time required to place and compact the HMA mixture, plane, remove asphalt, tack coat, and as needed. d. Any work in an intersection requires advance warning in both signage and a number of Working Days advance notice as determined by the Engineer, to alert traffic and emergency services of the intersection closure or partial closure. e. Allow new compacted HMA asphalt to cool to ambient temperature before any traffic is allowed on it. Traffic is not allowed on newly placed asphalt until approval has been obtained from the Engineer. 2. Temporary centerline marking, post-paving temporary marking, temporary stop bars, and maintaining temporary pavement marking must comply with Section 8-23. 3. Permanent pavement marking must comply with Section 8-22. 5-04.3(14)B2 Submittals – Planing Plan and HMA Paving Plan The Contractor must submit a separate planing plan and a separate paving plan to the Engineer at least 5 Working Days in advance of each operations activity start date. These plans must show how the moving operation and traffic control are coordinated, as they will be discussed at the pre-planing briefing and pre-paving briefing. When requested by the Engineer, the Contractor must provide each operations traffic control plan on 24 x 36 inch or larger size Shop Drawings with a scale showing both the area of operation and sufficient detail of traffic Kensington Drainage Improvements/Holcomb 5 - 28 February 14, 2022 Project Number: 18-3019 beyond the area of operation where detour traffic may be required. The scale on the Shop Drawings is 1 inch = 20 feet, which may be changed if the Engineer agrees sufficient detail is shown. The planing operation and the paving operation include, but are not limited to, metal detection, removal of asphalt and temporary asphalt of any kind, tack coat and drying, staging of supply trucks, paving trains, rolling, scheduling, and as may be discussed at the briefing.

The paving interlayer rolls shall be delivered and handled in a manner to prevent damage and shall be inspected for defects and damage prior to use. The paving interlayer shall be stored in a dry covered condition, free from dust, dirt, off the ground, flat to prevent bowing, protected from precipitation, ultraviolet radiation, strong chemicals, sparks and flames, temperatures in excess 71 °C (160 °F) and other environmental condition that could cause damage. WEATHER AND MOISTURE LIMITATIONS Work shall not be done during wet weather conditions nor when the pavement and ambient air temperatures are below 50°F. The pavement shall be surface-dry at the time of the application of the asphalt. Kensington Drainage Improvements/Holcomb 5 - 32 February 14, 2022 Project Number: 18-3019 SURFACE PREPARATION All areas of base failure shall be removed and replaced to acceptable industry standards for the specific traffic loads and condition of the project. Pre-Leveling, if necessary, shall be done prior to placing paving interlayer. The pavement surface shall be free of all foreign materials such as dirt, grease, etc. Prior to applying the asphalt, all dust and loose material shall be removed from the pavement surface with compressed air. Existing cracks shall be filled as specified elsewhere under Crack Sealing. In an overlay or milled surface application, repair all failed pavement areas prior to installation of the paving interlayer. Fill all cracks ¼ or greater with approved material. Immediately prior to placement of paving interlayer, the pavement surface shall be dry, cleaned of anything that would interfere with adhesion, for e.g., vegetation, moss, dirt, gravel or water. A leveling or "scratch" course is recommended when road surface is not acceptable and shall be of proper gradation and sufficient thickness to achieve a smooth, level surface with no gaps greater than ¼ depth and width or be acceptable to the project engineer. A finish grind may be used as an alternative to an asphalt leveling course being placed, when you can achieve the final surface texture has no cracks, gaps or vertical angles greater the ¼ depth and width or be acceptable to the project engineer. In all cases the surface must be clean and dry and the application rate of the Hot PG grade asphalt binder shall be increased to insure complete interlayer saturation and bonding. INSTALLATION A. Apply the asphalt interlay fabric in a hot PG graded asphalt binder. Asphalt Emulsion is NOT acceptable for placing paving interlayer due to time delay for it to break and the difficulty in insuring quality as installed. B. Asphalt Binder 1. A hot asphalt binder shall be applied to saturate the paving interlayer (min. to be the asphalt retention rate) plus amount needed to bond to existing surface and the new overlay. The asphalt binder to be used shall be PG58H 22 (PG64 -22) or higher. Sustained ambient temperatures (above 90º) may require a stiffer binder gradation like PG58V 22 (PG70 -22) or higher to improve set time and reduce risk of fabric pick-up under construction traffic. 2. The hot asphalt binder shall be applied per the paving interlayer manufacturer or as directed by the Engineer. For TenCate Mirafi MPM30 the hot asphalt binder shall be applied at a rate of 0.10 Gal/SY on a new HMA leveling surface. On an Kensington Drainage Improvements/Holcomb 5 - 33 February 14, 2022 Project Number: 18-3019 old smooth surface or a clean fine milled surface apply hot asphalt binder shall be applied at a rate of 0.12 Gal/SY. For Tensar GlasPave 25 the hot asphalt binder shall be applied at a rate of 0.15 Gal/SY on a new pavement surface, 0.17 Gal/SY on an aged oxidized surface, and a rate of 0.2 Gal/SY on a milled surface. 3. Spray application shall extend four (4) inches wider than width of paving interlayer on lap side. Hot asphalt binder application shall be wide enough to cover the entire width of engineered paving mat material overlaps. The hot asphalt binder shall be applied only as far in advance of the engineered paving mat material installation as is appropriate to ensure a tacky surface at the time of the engineered paving mat material placement. Traffic shall not be allowed on the hot asphalt binder. 4. The hot asphalt binder shall be applied by a distributor truck in a smooth uniform manner at as low a temperature as is possible to achieve the right application rate, depending on ambient and road surface temperatures and type of PG asphalt binder used. Temperature of the hot asphalt binder shall be sufficiently high enough to permit uniform spray pattern and shall be between 350º F and 400º F. The air temperature shall be 50º F and rising for placement of the hot asphalt binder coat. C. The paving interlayer shall be installed with equipment in good working order that is capable of installing the fabric without wrinkles or manually as needed and recommended by manufacturer. 1. Initial alignment of the interlay fabric is very important, since the fabric direction cannot be changed appreciably without causing wrinkles. If the alignment of the interlay fabric must be changed, the fabric shall be cut and realigned, overlapping the previous material and proceeding as before. 2. If manual lay-down methods are used, the paving fabric shall be unrolled, aligned, and placed in increments of approximately thirty (30) feet or as project engineer suggest. 3. The material shall be placed flat and wrinkle-free. The paving interlayer installation may require hand brooming as necessary to eliminate ripples that may occur during installation. 4. Brooming or squeegee of paving interlayer is required to insure adequate adhesion into the hot asphalt binder before the hot asphalt binder has cooled and lost tackiness. If the interlayer wrinkles more than 1 height during installation, the wrinkle shall be cut and lapped in the direction of paving. In these repaired areas, additional hot asphalt binder shall be Kensington Drainage Improvements/Holcomb 5 - 34 February 14, 2022 Project Number: 18-3019 applied as needed to achieve a sound bond to the substrate. Damaged engineered paving mat shall be removed and replaced, per the manufacturer's recommendations, at the contractor's expense with the same type of material. 5. To ease installations around curves, the paving fabric can be placed in shortened lengths by mechanical equipment or by hand. 6. Paving interlayer shall be lapped two (2) to four (4) inches longitudinally and two (2) to four (4) inches transversely. Transverse laps shall be in the direction of the asphalt concrete overlay placement insuring hot asphalt binder is placed under the overlap. The interlay fabric shall be neatly cut and contoured at all joints. 7. Excess hot asphalt binder that bleeds through the engineered paving mat under normal construction traffic shall be countered by broadcasting clean sand or hot mix to create a bond break between the excess hot asphalt binder and the construction equipment tires. Excess blotting sand shall be removed from the interlayer prior to placing the HMA overlay. No other material, such as asphalt release agents or diesel, shall be used for this purpose. 8. No traffic, except necessary construction traffic or emergency vehicles, shall be driven on the engineered paving mat, unless approved by the engineer. If traffic on the interlayer is approved by the engineer, clean sand shall be lightly broadcasted over the engineered paving mat interlayer, and any loose sand shall be removed prior to paving. 9. Turning of construction equipment and other vehicles shall be gradual and kept to a minimum to avoid damage to the paving interlayer. Caution: Parking on the installed paving fabric prior to final overlay for extended periods could cause damage to the interlayer. 10. Placement of the first lift of the HMA overlay shall closely follow placement of the engineered paving mat. All areas in which the engineered paving mat has been placed shall be paved during the same day, unless approved otherwise by the engineer. In the event of rainfall on the engineered paving mat prior to the placement of the first HMA overlay lift, the engineered paving mat shall be allowed to dry before the HMA is placed. The compacted thickness of the first lift of the HMA overlay on the engineered paving mat shall not be less than 1.5 inches, and the temperature of the mix at placement shall not exceed the engineered paving mat melting point temperature. Where the total HMA overlay thickness is less than 1.5 inches, engineered paving mat shall not be placed. NOTE: Minimum lift thickness should be at least 3 times the nominal maximum aggregate size to ensure aggregate can Kensington Drainage Improvements/Holcomb 5 - 35 February 14, 2022 Project Number: 18-3019 align themselves during compaction to achieve required density and also to ensure mix is impermeable. 11. Paving interlayer should never be installed when it or the pavement surface is wet. 12. The Contractor shall not place more interlay fabric on the roadway than can be overlaid the same day with Hot Mix Asphalt. No fabric, except that which is required for normal lapped joints, shall be exposed to traffic. 13. In the event of breakdown of the paving operation, the interlay fabric which has not been overlaid shall be dusted with sand to break the tackiness of the sealant so traffic does not pick up the fabric. The application rate shall uniformly dust the roadway as approved by the Engineer. More than one application of sand may be required. Before placing the asphalt concrete, the fabric surface shall be broomed to remove the excess sand as directed by the Engineer. The sand shall meet the graduation requirements of the Section 9-03.1(2)B of the WSDOT Standard Specifications. WORKMANSHIP AND QUALITY CONTROL A Technical Representative for the manufacturer of the paving interlayer shall be on the project to work with the Contractors personnel and to provide the necessary technical assistance to ensure the satisfactory placement of the interlay fabric and HMA overlay. The representative shall not leave the project until the Engineer is satisfied that the Contractor has a full understanding of what is required to place the interlay fabric satisfactorily. The installing contractor shall give sufficient notice of planned work schedule such that proper inspection of workmanship is accomplished. 1. Daily, the Contractor shall certify that interlayer was installed per plans and specifications and confirm, by weight tickets and measuring asphalt used, that the hot asphalt binder usage equates to the specified amount for proper interlayer saturation and bonding. 2. Hot asphalt binder application rate shall not be reduced without the Engineers approval. 3. Certification of compliance from the binder supplier shall be provided for each load of hot asphalt binder delivered to the jobsite, showing the type and quality of material delivered. 4. The Contractor shall provide satisfactory confirmation to the Engineer, for each Street Section, showing the total quantity of asphalt binder installed, at the proper application rate as published by the manufacturer.

The flushing of a sewer main tributary to a lift station shall be coordinated with the Operations Division to insure that the lift station is not overloaded. City water used for cleaning sewer lines is not metered, but shall pass through an approved double check valve assembly. SECTION 7-17.3(2)F IS SUPPLEMENTED BY ADDING THE FOLLOWING: 7-17.3(2)F Low Pressure Air Test for Sanitary Sewers Constructed of Non Air Permeable Materials All testing shall be verified by the City Inspector. All sewer mains and appurtenances shall be air pressure tested for leakage in accordance with Section 7-17 of the WSDOT Standard Specifications as modified by the following: Procedure for Air Testing Sanitary Sewer Lines For PVC and Ductile Iron Pipe - The Contractor shall furnish all facilities and personnel for conducting the test under the observation of the Engineer. The equipment and personnel shall be subject to the approval of the Engineer. The Contractor may desire to make an air test prior to backfilling for its own purposes. However, the acceptance air test shall be made after backfilling has been completed and compacted. All wyes, tees, or ends of side sewer stubs shall be plugged with flexible-joint caps, or acceptable alternates, securely fastened to withstand the internal test pressures. Such plugs or caps shall be readily removable, and their removal shall provide a socket suitable for making a flexible-jointed lateral connection or extension. Immediately following pipe cleaning, the pipe installation shall be tested with low-pressure air. Air shall be slowly supplied to the plugged pipe installation until the internal air pressure reaches 4.0 pounds per square inch greater than the average back pressure of any ground water that may submerge the pipe. At least two minutes shall be allowed for temperature stabilization before proceeding further. Then, disconnect the air supply and wait until the pressure drops to 3.5 psig greater than the average back pressure of groundwater. The pressure shall be held to the time indicated on the attached tables. Kensington Drainage Improvements/Holcomb 7 - 15 February 14, 2022 Project Number: 18-3019 Groundwater Pressure p = 0.4332 (z) z = Distance between groundwater surface and centerline of pipe in feet. p = Average back pressure of groundwater above the centerline of the pipe in psi. If the pipe installation fails to meet these requirements, the Contractor shall determine at its own expense the source or sources of leakage, and he shall repair (if the extent and type of repairs proposed by the Contractor appear reasonable to the Engineer) or replace all defective materials or workmanship. The completed pipe installation shall meet the requirements of this test before being considered acceptable. Caution When air testing adequate bracing is required to hold plugs in place to prevent the sudden release of compressed air. A pressure of 4 psig against an 8-inch plug will cause a force of approximately 200 lbs.; against a 12-inch plug, 450 lbs. The compressed air acts as a spring. Proper precaution must be taken to prevent this force from propelling the plug from the pipe like a bullet. For systems where groundwater is negligible, at the inspectors discretion, pressure shall be maintained at 4.0 psig with no drop at the time indicated on the attached graphs.

Report Limitations and Guidelines for Use June 28, 2021 | Page 1 File No. 0410-217-00 1.0 INTRODUCTION AND PROJECT UNDERSTANDING This report presents the results of our geotechnical reconnaissance and geotechnical recommendations for the Kensington Ravine project. The project site is located about 500 feet south of the intersection of Kensington Avenue South and Reiten Road in Kent, Washington as shown on the Vicinity Map, Figure 1. We previously issued a technical memorandum for the project dated June 23, 2021 that provides hydraulic analysis and recommendations (Hydraulic Analysis Memorandum). We were provided two sheets from preliminary plans including a site plan and typical sections prepared by the City of Kent (the City) dated June 8, 2021. Stationing discussed herein references the stationing shown on the provided plan sheets, which are attached to this report as Appendix A. We understand that the City plans to construct a new drainage ditch with components to reduce flow velocities and prevent erosion. Based on review of the provided plans, the improvements will include two gabion basket check dams, reinforced slopes, and rock armoring. The new ditch will be trapezoidal and cut to grade in the same general location as the existing ditch. Water within the new ditch will be directed to a Type 2 catch basin structure near Kensington Avenue South. Due to steep slopes at the site, it is our understanding that the site is designated as a critical area. 2.0 PURPOSE AND SCOPE OF SERVICES The purpose of our services is to complete a geologic reconnaissance at the project site to provide our opinion on the current stability of the slope and evaluate potential impacts to slope stability due to the proposed improvements. We will also provide geotechnical design recommendations pertaining to the proposed improvements. Our services have been completed in accordance with our signed agreement for this project executed on May 18, 2021. A complete list of our authorized services is provided in the signed agreement. 3.0 SITE CONDITIONS 3.1. Geologic Setting We reviewed the Geologic Map of the Tacoma 1:100,000-scale Quadrangle, Washington (Schuster et al.). According to the map, soils in the near site vicinity include Vashon drift (Qgd) and Salmon Springs Drift (Qgps). Both units are glacially consolidated soils and described to consist of a mixture of clay, silt, sand, and gravel. The upper few feet of glacially consolidated deposits can be weathered and in a loose to medium dense condition. Undisturbed glacially consolidated soils are dense to very dense. 3.2. Slope Reconnaissance We performed a visual reconnaissance of the site on May 24, 2021. Per Chapter 11.06 Critical Areas of the Kent City Code, the project site is designated as a critical area for landslide hazard due to having slopes greater than 40 percent with vertical relief of more than 10 feet. Kensington Ravine is located about 500 feet south of the intersection of Kensington Avenue South and Reiten Road in Kent, Washington. The top of the ravine is located near the western terminus of East Tacoma Street and the bottom of the ravine June 28, 2021 | Page 2 File No. 0410-217-00 is located near Kensington Avenue South. The top of the ravine generally trends to the west and then turns northwest towards Kensington Avenue South. Total grade change along the ravine is on the order of 60 feet. The ravine is heavily vegetated with trees and underbrush. We observed surface water at the base of the ravine that, in some areas, appears to have eroded a narrow channel up to about 6 feet deep. Observed surface water, where present, was typically a few inches deep. In the north portion of the ravine (from approximate Station 10+00 to 11+50) steep banks form its sides. The banks are up to about 15 to 20 feet tall with near vertical slopes. We expect the steep banks were formed from localized surficial erosion at the site. The steep banks of the ravine and the sidewalls of eroded channels generally expose silty sand with variable gravel content, visually consistent with glacially consolidated soils mapped within the project area. We observed exposed soil to generally be in a dense condition. During our reconnaissance we did not observe significant signs of deep-seated slope failure such as pistol- butted trees near the top of the banks or groundwater seepage emitting from the faces of the banks. We did not observe signs of tension cracks forming or surface settlement at the crest of the slope nor the top of the steep banks; however, due to heavy vegetation and difficult access, some of these areas were unable to be observed directly. 4.0 CONCLUSIONS AND RECOMMENDATIONS 4.1. Slope Evaluation 4.1.1. Slope Stability Modeling In addition to our site reconnaissance, we evaluated the stability of the ravine bank at approximate Station 11+10 as shown on Sheet 4 of the provided plans (Appendix A). Based on review of the provided plans, it appears that the area near Station 11+10 represents a typical steep slope condition. We performed two slope stability analyses at this location, which are presented as Figures 2 and 3. Slope stability was evaluated using the GeoStudio commercial software Slope/W. The critical slip surface and corresponding factor of safety (FS) were determined using the Morgernstern-Price limit equilibrium method. The minimum slip surface depth used in our analyses was set to 5 feet in order to evaluate non- surficial slope failures. Since we did not perform subsurface explorations at the site, soil type and conditions are generally unconfirmed at depth. However, as previously discussed we did observe some exposed soils consistent with glacially consolidated soils. We estimated soil strength parameters in our slope stability analysis using our observations in the field and our understanding of local geologic conditions. Additionally, we calibrated soil strength parameters of the site soils (glacially consolidated soils) based on existing site topography and the presence of the steep banks that appear to be stable (i.e., FS equal to or greater than 1). Soil strength parameters for the rock fill (Class B riprap) were estimated using typical values presented in Chapter 5 of the Washington State Department of Transportation (WSDOT) Geotechnical Design Manual. Figure 2 presents our stability analysis of the ravine bank at Station 11+10 in its current state. Note that the stability analysis shown in Figure 2 was used to calibrate the soil strength parameters of the glacially June 28, 2021 | Page 3 File No. 0410-217-00 consolidated soils; soil strength parameters were increased in the model until a stable condition was achieved. Figure 3 presents the stability analysis at of the ravine bank at Station 11+10 after the proposed improvements, which include placement of rock fill as recommended in our Hydraulic Analysis Memorandum. Rock fill consists of Class B riprap that lines a 2.5-foot-wide channel, is embedded 2.5 feet and extends up the banks a height of 1.5 feet above the bottom of the channel. The global stability analysis results are summarized below in Table 1. TABLE 1. SUMMARY OF SLOPE STABILITY RESULTS Global Stability Case FS Static, Existing Conditions 1.0 Static, Post-Construction 1.8 4.1.2. Conclusions Based on our observations during our site reconnaissance it is our opinion that there is a low risk of deep- seated or global failures and instability of the slopes near the proposed improvements. Based on our analysis it is also our opinion that the proposed development will not significantly impact the stability of the adjacent slope and will result in a net increase in factor of safety of the banks. The proposed armoring will reduce the potential for further erosion and will provide a buttress effect at the toe of the banks. Existing slopes could still experience shallow surficial sloughing over the long term. Sloughing is typically due to natural weathering processes such as seepage, saturation of shallow soils during heavy rain events, decay of roots, or root removal of blown down trees. The magnitude and volume of material involved in shallow surficial sloughing depends on several factors including steepness of slope, time of year, rainfall, saturation of ground, and activity of burrowing animals. Sloughing is a natural process that occurs with or without development. The risk of sloughing will remain even after the project is completed. The purpose of the project and the overall effect of the project will be to reduce erosion and thereby increase slope stability. As such, it is our opinion, the remaining landslide hazards as defined should not be considered a limiting factor for the proposed development. 4.2. General Site Development and Earthwork Recommendations We anticipate site development and earthwork activities will include: clearing and stripping vegetated areas, site grading, establishing subgrades for project improvements; and placing and compacting fill material. We expect that site grading and earthwork can be accomplished primarily with conventional earthmoving equipment. Some specialized equipment could be required due to space constraints. 4.2.1. Temporary Erosion and Sedimentation Control Erosion and sedimentation rates and quantities can be influenced by construction methods, slope length and gradient, amount of soil exposed and/or disturbed, soil type, construction sequencing and weather. Implementing an Erosion and Sedimentation Control Plan will reduce the project impact on erosion-prone areas. The plan should be designed in accordance with applicable city, county, and state standards. The plan should incorporate basic planning principles, including: Scheduling grading and construction to reduce soil exposure; June 28, 2021 | Page 4 File No. 0410-217-00 Re-vegetating or mulching denuded areas; Directing runoff away from exposed soils; Reducing the length and steepness of slopes with exposed soils; Decreasing runoff velocities; Preparing drainage ways and outlets to handle concentrated or increased runoff; Confining sediment to the project site; Inspecting and maintaining control measures frequently. Some sloughing and raveling of exposed or disturbed soil on slopes should be expected. We recommend disturbed soil be restored promptly so that surface runoff does not become channeled. Temporary erosion protection should be used and maintained in areas with exposed or disturbed soils to help reduce erosion and reduce transport of sediment to adjacent areas and receiving waters. Permanent erosion protection should be provided by the proposed developments. Until the permanent erosion protection is established and the site is stabilized, site monitoring may be required by qualified personnel to evaluate the effectiveness of the erosion control measures and to repair and/or modify them as appropriate. Provisions for modifications to the erosion control system based on monitoring observations should be included in the Erosion and sedimentation Control Plan. 4.2.2. Temporary Excavations and Cut Slopes We anticipate that shallow excavations could experience minor caving. Excavations deeper than 4 feet should be shored or laid back at a stable slope if workers are required to enter. Shoring and temporary slope inclinations must conform to the provisions of Title 296 Washington Administrative Code (WAC), Part N, Excavation, Trenching and Shoring. Regardless of the soil type encountered in the excavation shoring, trench boxes or sloped sidewalls will be required under Washington Industrial Safety and Health Act (WISHA). We recommend the contract documents specify that the contractor is responsible for selecting excavation and dewatering methods, monitoring the excavations for safety and providing shoring, as required, to protect personnel and structures. Glacially consolidated soils can maintain near vertical cut slopes for a time. However, near vertical slopes in these soils can also slough quickly and without warning. In general, we recommend that for planning purposes all temporary cut slopes be inclined no steeper than about 1.5H:1V (horizontal:vertical) if workers are required to enter confined trenches. Temporary cut slopes in dense glacially consolidated soil can be cut to steeper inclinations provided that a collapse or slough of the slope will not endanger workers or adjacent property. This guideline assumes all surface loads are kept at a minimum distance of at least one- half the depth of the cut away from the top of the slope and that seepage is not present on the slope face. Flatter cut slopes will be necessary where seepage occurs or if surface surcharge loads are anticipated. Temporary covering with heavy plastic sheeting should be used to protect these slopes during periods of wet weather. June 28, 2021 | Page 5 File No. 0410-217-00 4.2.3. Permanent Cut and Fill Slopes We recommend permanent soil slopes be constructed at a maximum inclination of 2H:1V to manage erosion. Where 2H:1V permanent slopes are not feasible, protective facings and/or retaining structures should be considered. Rock fill placed as part of the ditch improvements will have inclinations exceeding 2H:1V; however, it is our opinion that provided the slope is rebuilt using rock fill as recommended in this report, steeper inclinations (on the order of 1H:1V) are acceptable. Exposed areas should be re-vegetated as soon as practical to reduce the surface erosion and sloughing. Temporary protection should be used until permanent protection is established. 4.2.4. Temporary Groundwater Handling Considerations We observed surface water in some areas at the base of the ravine during our slope reconnaissance, which we expect could be a combination of surface water runoff and perched groundwater seepage. We anticipate groundwater levels will vary throughout the year and will generally be highest during the wet season, typically October through May. We expect that perched groundwater and surface water could be encountered depending on the time of year of construction, likely near contacts where soil that is more permeable overlies soil that is less permeable (i.e., weathered glacially consolidated soils over glacially consolidated soils) or flowing at the base of the ravine. Groundwater handling needs will typically be lower during the late summer and early fall months. We anticipate shallow perched groundwater can typically be handled adequately with diversion ditches, and/or sumps and pumps, as necessary. If rock fills are constructed in the summer months it is expected that the seepage can be allowed to flow through the fill as it is placed and that it will not inhibit rock fill placement. Ultimately, we recommend the contractor performing the work be made responsible for controlling and collecting groundwater encountered. 4.2.5. Subgrade Protection and Wet Weather Considerations Site soils observed typically contain a significant amount of fines and will be susceptible to disturbance during periods of wet weather. Soil with high fines content is very sensitive to small changes in moisture and is susceptible to disturbance from construction traffic when wet or if earthwork is performed during wet weather. When the moisture content of the soil is more than a few percent above the optimum moisture content, this soil can become unstable and it will be challenging to meet the required compaction criteria. The wet weather season generally begins in October and continues through May in western Washington; however, periods of wet weather can occur during any month of the year. In our opinion, earthwork will be most efficient during the summer months or during periods of extended dry weather. If wet weather earthwork is unavoidable, we offer the following recommendations: The ground surface in and around the work area should be sloped so that surface water is directed away from the work area. The ground surface should be graded so that areas of ponded water do not develop. Measures should be taken by the contractor to prevent surface water from collecting in excavations and trenches. Measures should be implemented to remove surface water from the work area. Earthwork activities should not take place during periods of heavy precipitation. Slopes with exposed soils should be covered with plastic sheeting. June 28, 2021 | Page 6 File No. 0410-217-00 The contractor should take necessary measures to prevent on-site soils and other soils to be used as fill from becoming wet or unstable. These measures may include the use of plastic sheeting, sumps with pumps and grading. The site soils should not be left uncompacted and exposed to moisture. Sealing exposed soils by rolling with a smooth-drum roller prior to periods of precipitation will help reduce the extent to which these soils become wet or unstable. Construction traffic should be restricted to specific areas of the site, preferably areas that are surfaced with working pad materials not susceptible to wet weather disturbance. Construction activities should be scheduled so that the length of time that soils are left exposed to moisture is reduced to the extent practical. 4.3. Drainage Ditch Improvements 4.3.1. General We understand that currently proposed plans pertaining to geotechnical improvements include reinforced slopes and rock armoring in order to construct the new ditch alignment. 4.3.2. Site Preparation Prior to placement of fill, the improvement area should be cleared and stripped of all vegetation and organics. Based on conditions observed during our site reconnaissance, minimum stripping depths at the site will likely be on the order of 4 to 6 inches. However, greater stripping depths could be required to remove localized zones of loose or organic-rich soil. We anticipate that some trees will need to be removed prior to excavation. During clearing and stripping, stumps and primary root systems of shrubs and trees should be completely removed from fill areas. Voids caused by removal of stumps and/or root systems should be backfilled with rock fill, described below. If trees are removed from steep slopes for access purposes, the root system can be left intact to allow for slope and erosion protection as new vegetation is being established. We anticipate soils exposed after stripping will have a high fines content and will, therefore, be susceptible to disturbance when wet. Care should be taken to avoid allowing these soils to become saturated and disturbed. Based on review of the provided plans, it appears that most of the ditch improvements will consist of placement of fill with limited excavation. Fill subgrades should be free of organics and expose firm and unyielding soils. In areas of excavation, excavation should extend to expose firm and unyielding on-site soils. Based on our observations, we expect that excavated material will consist of medium dense to very dense silty sand with gravel. Provided excavations are relatively shallow, we anticipate these soils can be excavated with conventional excavation equipment such as midsize excavators. If smaller equipment such as mini excavators are required due to site space constraints, additional tools and attachments such as hydraulic breakers or chisels could be required for efficient excavation. Cobbles and/or boulders could be encountered, and the contractor should be prepared to deal with these during construction. After subgrades are established, we recommend installation of a geotextile fabric over the subgrade prior to placement of rock fill. Geotextile fabric should conform to WSDOT Standard Specification 9-33 Construction Geotextile for Soil Stabilization (Table 3). June 28, 2021 | Page 7 File No. 0410-217-00 4.3.3. Rock Fill Placement, Materials, and Compaction Place and compact rock fill on the prepared subgrades as ditch lining material. As discussed in our Hydraulic Analysis Memorandum, rock fill should consist of Class B riprap, extend to a height of at least 1.5 feet above the proposed channel bottom and have a thickness below proposed grade of at least 2.5 feet. For areas of rock fill extending up the sides of the ditch, we recommend that they be placed no steeper than 1H:1V. Rock fill should be free of debris and organic contaminants. We recommend rock fill consist of material similar to Class B riprap as described in Section 9-13.4(3) of the WSDOT Standard Specifications. Rock fill should be placed in lifts and compacted and locked in via mechanical means, such as tamping with an excavator bucket or use of vibratory compaction equipment. 4.3.4. Other Fill Placement, Materials and Compaction In addition to rock fill areas, other parts of the site may need to be filled. We expect that this could include placement of fill to attain rock fill subgrade elevation, such as filling the eroded narrow channels previously discussed. In our opinion, on-site soil could be used as fill in these areas provided it does not contain organics and can be adequately compacted. The on-site soils observed and anticipated at the site are extremely moisture sensitive and will be very difficult or impossible to properly compact when wet or when placed over wet subgrade. If earthwork occurs during the wet season, or if the soils and/or subgrades are persistently wet and cannot be dried back to near optimum due to prevailing wet weather and site conditions, we recommend the use of imported granular fill. Imported granular fill should consist of material similar to Select Borrow or Gravel Borrow as described in Section 9-03.14 of the WSDOT Standard Specifications. Fill should be placed in maximum 12-inch-thick lifts and compacted to at least 95 percent of the theoretical maximum dry density (MDD) per ASTM International (ASTM) D 1557. We expect that relatively small or narrow fill areas, such as the eroded channels, may need to be widened prior to filling in order to accommodate the size of compaction equipment. 5.0 LIMITATIONS We have prepared this report for City of Kent for the Kensington Ravine project in Kent, Washington. City of Kent may distribute copies of this report to their authorized agents and regulatory agencies as may be required for the project. Our services were provided to assist in the design of improvements located on and adjacent sloping property. Our recommendations are intended to improve the overall stability of the site and to reduce the potential for future damage related to earth movements, drainage or erosion. Qualified engineering and construction practices can help mitigate the risks inherent in construction on slopes, although those risks cannot be eliminated completely. Favorable performance of structures in the near term is useful information for anticipating future performance, but it cannot predict or imply a certainty of long-term performance, especially under conditions of adverse weather or seismic activity.

GeoEngineers considered a number of unique, project-specific factors when establishing the scope of services for this project and report. Unless GeoEngineers specifically indicates otherwise, it is important not to rely on this report if it was: not prepared for you, not prepared for your project, not prepared for the specific site explored, or completed before important project changes were made. For example, changes that can affect the applicability of this report include those that affect: the function of the proposed structure; elevation, configuration, location, orientation or weight of the proposed structure; 1 Developed based on material provided by GBA, GeoProfessional Business Association; www.geoprofessional.org. June 28, 2021 | Page B-2 File No. 0410-217-00 composition of the design team; or project ownership. If changes occur after the date of this report, GeoEngineers cannot be responsible for any consequences of such changes in relation to this report unless we have been given the opportunity to review our interpretations and recommendations. Based on that review, we can provide written modifications or confirmation, as appropriate. Environmental Concerns are Not Covered Unless environmental services were specifically included in our scope of services, this report does not provide any environmental findings, conclusions, or recommendations, including but not limited to, the likelihood of encountering underground storage tanks or regulated contaminants. Subsurface Conditions Can Change This geotechnical or geologic report is based on conditions that existed at the time the study was performed. The findings and conclusions of this report may be affected by the passage of time, by man-made events such as construction on or adjacent to the site, new information or technology that becomes available subsequent to the report date, or by natural events such as floods, earthquakes, slope instability or groundwater fluctuations. If more than a few months have passed since issuance of our report or work product, or if any of the described events may have occurred, please contact GeoEngineers before applying this report for its intended purpose so that we may evaluate whether changed conditions affect the continued reliability or applicability of our conclusions and recommendations. Geotechnical and Geologic Findings are Professional Opinions Our interpretations of subsurface conditions are based on field observations from widely spaced sampling locations at the site. Site exploration identifies the specific subsurface conditions only at those points where subsurface tests are conducted or samples are taken. GeoEngineers reviewed field and laboratory data and then applied its professional judgment to render an informed opinion about subsurface conditions at other locations. Actual subsurface conditions may differ, sometimes significantly, from the opinions presented in this report. Our report, conclusions and interpretations are not a warranty of the actual subsurface conditions. Geotechnical Engineering Report Recommendations are Not Final We have developed the following recommendations based on data gathered from subsurface investigation(s). These investigations sample just a small percentage of a site to create a snapshot of the subsurface conditions elsewhere on the site. Such sampling on its own cannot provide a complete and accurate view of subsurface conditions for the entire site. Therefore, the recommendations included in this report are preliminary and should not be considered final. GeoEngineers recommendations can be finalized only by observing actual subsurface conditions revealed during construction. GeoEngineers cannot assume responsibility or liability for the recommendations in this report if we do not perform construction observation. We recommend that you allow sufficient monitoring, testing and consultation during construction by GeoEngineers to confirm that the conditions encountered are consistent with those indicated by the explorations, to provide recommendations for design changes if the conditions revealed during the work June 28, 2021 | Page B-3 File No. 0410-217-00 differ from those anticipated, and to evaluate whether earthwork activities are completed in accordance with our recommendations. Retaining GeoEngineers for construction observation for this project is the most effective means of managing the risks associated with unanticipated conditions. If another party performs field observation and confirms our expectations, the other party must take full responsibility for both the observations and recommendations. Please note, however, that another party would lack our project- specific knowledge and resources. A Geotechnical Engineering or Geologic Report Could Be Subject to Misinterpretation Misinterpretation of this report by members of the design team or by contractors can result in costly problems. GeoEngineers can help reduce the risks of misinterpretation by conferring with appropriate members of the design team after submitting the report, reviewing pertinent elements of the design teams plans and specifications, participating in pre-bid and preconstruction conferences, and providing construction observation. Do Not Redraw the Exploration Logs Geotechnical engineers and geologists prepare final boring and testing logs based upon their interpretation of field logs and laboratory data. The logs included in a geotechnical engineering or geologic report should never be redrawn for inclusion in architectural or other design drawings. Photographic or electronic reproduction is acceptable, but separating logs from the report can create a risk of misinterpretation. Give Contractors a Complete Report and Guidance To help reduce the risk of problems associated with unanticipated subsurface conditions, GeoEngineers recommends giving contractors the complete geotechnical engineering or geologic report, including these Report Limitations and Guidelines for Use. When providing the report, you should preface it with a clearly written letter of transmittal that: advises contractors that the report was not prepared for purposes of bid development and that its accuracy is limited; and encourages contractors to conduct additional study to obtain the specific types of information they need or prefer. Contractors are Responsible for Site Safety on Their Own Construction Projects Our geotechnical recommendations are not intended to direct the contractors procedures, methods, schedule or management of the work site. The contractor is solely responsible for job site safety and for managing construction operations to minimize risks to on-site personnel and adjacent properties. Biological Pollutants GeoEngineers Scope of Work specifically excludes the investigation, detection, prevention or assessment of the presence of Biological Pollutants. Accordingly, this report does not include any interpretations, recommendations, findings or conclusions regarding the detecting, assessing, preventing or abating of Biological Pollutants, and no conclusions or inferences should be drawn regarding Biological Pollutants as they may relate to this project. The term Biological Pollutants includes, but is not limited to, molds, fungi, spores, bacteria and viruses, and/or any of their byproducts.

I am pleased to inform you that the City of Kent hereby grants approval of the report. The report is approved as of the date of this letter. The city agrees that the site does not contain conditions to be considered a wetland, as determined by ICF. Review of the ICF report and the residential areas adjacent to the ravine determined the channel is an ephemeral system meaning that water exists only because of storm precipitation. Fish do not use the ravine. The upstream and downstream areas are shallow roadside ditches and curbs on slopes that direct water off the roads and through the residential area. Per the applicants report Kensington Ravine is not regulated by the Kent City Code 11.06. The City of Kent concurs with the report finding that Kensington Ravine is not regulated by the Kent City Code 11.06. Should you have any questions regarding this letter, please contact me by phone at (253) 856-6449 or email at salcorn@KentWa.gov Sincerely, Sam Alcorn, Planner Enclosed: Kensington Wetland/Stream Review RECR 2211164 Kensington Drainage Improvements/Holcomb A - 5 February 14, 2022 Project Number: 18-3019 CONSTRUCTION STORMWATER POLLUTION PREVENTION PLAN PUBLIC WORKS DESIGN ENGINEERING Carla Maloney, P.E. Design Engineering Manager 400 West Gowe Kent, WA 98032 Fax: 253-856-6500 PHONE: 253-856-5500 City of Kent Public Works Department Chad Bieren, P.E., Public Works Director Date: June 22, 2021 To: File cc: Shawn Gilbertson, Environmental Supervisor Derek Hawkes, Engineering Supervisor Matt Coy, Environmental Compliance From: Drew Holcomb, P.E., Design Engineer, Regarding: Tacoma St Kensington Ave Drainage Improvement Project Construction Stormwater Pollution Prevention Plan (CSPPP) Project Summary. In the Scenic Hill neighborhood of the City of Kent, there is an existing drainage ditch known as Kensington Ravine that runs from the unopened right of way of Tacoma St. down through the woods to a catch basin on Kensington Ave. This ravine is approximately 350 LF long and drains approximately 23 acres through City right of way and easements on three properties, 807 Tacoma St.; 118 Kensington Ave. S.; and 120 Kensington Ave S. Slopes of the existing wooded ravine vary from approximately 15% to 45%. City outfalls onto one man rock that they have placed at the top of the ditch. This rock has mostly remaining in place since it was added a few years ago, however, it only lines the existing glacial till soil and deposited it downstream. After the placed rock, the ditch continues downhill with varying ditch width and depth. Most concerning is the section - which are being washed downstream and often plug the ravine outlet. The stream drains into a Type 1L catch basin with a trash rack located in an easement directly adjacent to is connected to the City storm system which drains through a pipe, then a swale and then is piped to the Mill Creek Earthworks Dam Park where the stormwater outfalls to Mill Creek. Site Conditions This continually eroding ravine often plugs the outlet grate and causes flooding on the downstream property as well as washouts onto the Kensington Ave. roadway and is a constant maintenance burden for City Drainage Staff especially during periods of intense rainfalls when crews are busy in other parts of the City. This project will maintain this drainage ditch by constructing an open flow channel with large rock to slow the high velocity flow and prevent wash outs. This project will add gabion baskets to prevent additional erosion on the side slopes of the ditch and create check dams to further reduce the water velocity and sediment migration downstream. A new catch basin and trash rack will be installed to reduce instances of the outlet being plugged. Soils The exposed soils on the site are comprised of dense glacial soils at depth. There are some areas of relatively loose/soft surficial material (i.e. forest duff/weathered soils) typical of vegetated slopes. Erosion Construction of this project will require clearing of vegetation and removal of one tree on steep side slopes to access the ditch and place the rock. The exposed soils have the potential to be washed downstream should it rain while they are exposed. In this case the contractor shall cover exposed soil with plastic to prevent it from washing downstream. Construction Schedule and Phasing This project shall be constructed during the dry season to minimize any potential TESC concerns. Phasing to minimize exposed soils on this site will be challenging because of existing steep slopes and lack of access. The contractor will likely access the site by clearing and working their way up the ditch and then placing the rock at the top and working their way down the ditch. Required Elements Element 1: Preserve Vegetation/Mark Clearing Limits Prior to land disturbing activities, including clearing and grading, clearly mark all clearing limits, sensitive areas and their buffers, and trees that are to be preserved within the construction area, both in the field and on the plans, to prevent damage and offsite impacts. Clearing limits shown on plans. Element 2: Establish Construction Access Construction Vehicles can damage or compact soils, create sediment pollution, or track sediment onto public roads. Construction access points are shown on the plans. Element 3: Control Flow Rates Stormwater on a cleared site can create significant flows that can damage downstream properties. This purpose of this project is to control the flow rate of the existing ditch and decrease scour and erosion because it is currently causing problems downstream. We will accomplish this by widening the channel, covering exposed soils with a non-woven geotextile fabric and placing large rock to in the channel to reduce flow velocity. Additionally, we plan to install gabion basket chec reduce velocity in the ditch. Unfortunately, during construction this site does not easily allow for a bypass of stormwater or similar due to it being a drainage ditch. However, exposed side slopes will be covered with plastic in the event of rain and the ditch soils will not be exposed anymore than existing conditions prior to placing the geotextile fabric. Element 4: Install Sediment Controls When land is devegetated, stormwater can pick up sediment, a pollutant. BMPs can prevent sediment from leaving the site. The plans call for the installation of straw wattles on the side slopes. If these are easily overwhelmed or as directed by the engineer, the contractor will install silt fencing or other appropriate BMPs. Element 5: Stabilize Soils Leaving soils devegetated or exposed needlessly creates erosion and sediment problems. No soils will be exposed for more than two days from October 1 to April 30 and no longer than seven days the rest of the year. Exposed side slopes will be covered with jute matting. When rain is forecasted, exposed soils will be covered and secured with plastic. Some sloughing and raveling of exposed or disturbed soil on slopes should be expected. Disturbed soils shall be restored promptly so that surface runoff does not become channeled. Temporary erosion protection shall be used and maintained in areas with exposed or disturbed soils to help reduce erosion and reduce transport of sediment to adjacent areas and receiving waters. Permanent erosion protection will be provided by the proposed project. Element 6: Protect Slopes Slopes can be especially vulnerable to erosion, but BMPs can mitigate sediment problems. No soils will be exposed for more than two days from October 1 to April 30 and no longer than seven days the rest of the year. Exposed side slopes will be covered with jute matting. When rain is forecasted, temporary covering with heavy plastic sheeting will be used to protect these slopes during periods of wet weather. Shallow excavations could experience minor caving. Excavations deeper than 4 feet should be shored or laid back at a stable slope if workers are required to enter. Glacially consolidated soils can maintain near vertical cut slopes for a time. However, near vertical slopes in these soils can also slough quickly and without warning. Element 7: Protect Drain Inlets Storm drains are designed to collect and transport clean stormwater, not water polluted with sediment. Storm drain inlets must be protected so that runoff does not enter the stormwater system without first being filtered or treated to remove sediment. Silt socks will be inserted in downstream catch basins. Element 8: Stabilize Channels and Outlets Stormwater channels and outlets can themselves erode unless stabilized with rock or other armoring. This purpose of this project is to stabilize the existing ditch and decrease scour and erosion. We will accomplish this by widening the channel, cover exposed soils with a non-woven geotextile fabric and place large rock to in the channel to reduce flow velocity. Element 9: Control Pollutants Waste materials, demolition debris, and other pollutants that occur onsite during construction can contaminate the stormwater system unless managed. Cement and related products can modify the pH of stormwater. The Contractor shall prepare a Type 2 Working Drawing consisting of a project-specific spill prevention, control, and countermeasures plan (SPCC Plan), and shall implement the plan for the duration of the project. No on-site construction activities may commence until the Contracting Agency accepts an SPCC Plan for the project. An SPCC Plan template and guidance information is available at www.wsdot.wa.gov/environment/technical/disciplines/hazardous-materials/spill- prevent-report. The SPCC Plan shall address all fuels, petroleum products, hazardous materials, and other materials defined in Chapter 447 of the WSDOT Environmental Manual M 31-11. Occupational safety and health requirements that may pertain to SPCC Plan implementation are contained in, but not limited to, WAC 296-824 and WAC 296-843. The SPCC Plan shall address conditions that may be required by Section 3406 of the current International Fire Code, or as approved by the local Fire Marshal. Element 10: Control De-Watering De-watering water extracted from foundations, vaults, or trenches, has similar characteristics to stormwater runoff at the site and can cause the same impacts unless properly managed. This element does not apply to this project because no dewatering of the site is anticipated. Element 11: Maintain BMPs Best Management Practices (BMPs) are activities, protective measures, and maintenance procedures that, when used singly or in combination, prevent or reduce the impacts of erosion and sediment transport. All temporary and permanent erosion and sediment control BMPs must be maintained and repaired as needed to assure continued performance of their intended function. Sediment control BMPs must be inspected weekly or after a runoff producing storm event during the dry season and daily during the wet season. Element 12: Manage the Project Phasing a project, especially when revegetation occurs as part of each phase, can help prevent the transport of sediment from the site. This Construction SWPPP will be fully implemented at all times and modified and approved as directed by the engineer or whenever there is a change in design, construction, operation, or maintenance at the construction site that has or could have a significant effect on the discharge of pollutants to waters of the state. Element 13: Protect Low-Impact Development BMPs Low-Impact Development techniques can be damaged if they are compacted or accumulate sediment during construction. This element does not apply to this project because there are no Low-Impact Development BMPs planned. SWPPS MEASURES Each of the following categories of Stormwater Pollution Prevention and Spill Control (SWPPS) Standards measures must be considered for application to the project site. The SWPPS standards are located in the King County Surface Water Design Manual, Construction Stormwater Pollution Prevention Standards adopted as Appendix D: Follow effective pollutant handling and disposal procedures. Provide cover and containment for materials, fuel and other pollutants. Manage the project site to maximize pollutant control and minimize pollutant sources. Protect from spills and drips of petroleum products and other pollutants. Avoid over application or untimely application of chemicals and fertilizers. Prevent or treat contamination of stormwater runoff by pH modifying sources.
