POLICY AND PURPOSE
The City of Kent has adopted these Design and Construction Standards (hereinafter'Standards')
for two primary reasons:
1. To the extent practicable, to set forth the minimum requirements for specific and
consistent construction of and improvements to: public and private streett water
utilities, sewer utilities, and storm water utilities; placement and operation of any
utilities in rights-of-way;and all excavation and grading in the City.These Standards
include procedures for inspection, acceptance, warranty and deviations'
2. To establish uniform criteria to guide the City's own design, construction and
improvement of City streets and utilities.
These Standards are crafted to enable the Cityto achieve goals for neighborhood and
transportation connectivity, transportation safety, affordable housing, storm water management,
environmental protection, and cultural resource enhancement in balance with sound and
efficient development.
With respect to transportation, the City requires consistent standards to assure, so far as practical,
that motoring, bicycling, transit, and pedestrian safety needs are met in compliance with
requirementifor public safery convenience, aesthetics, surface water drainage, economical
maintenance, and cultural and environmental resource protection.
Given that the City must have flexibility to carry out its paramount duty to provide for the diverse
and changing needs of the traveling publig these Standards are not intended to represent the
legal standard by which the City's duty to the traveling public is to be measured.
These Standards cannot provide details for all situations.They are intended to guide, but not
to substitute for, competent work by licensed professional surveyors, architects and engineers.
The City recognizes that these professionals must use their best judgment and skill in design
and construction decisiont and must consider manyfactors including, but not limited to,
environmental constraints, existing geometry and sub-surface conditions. For its own projects,
the City faces the additional factor of limited economic resources which are constrained by limits
upon taxing authority.
These Standards are not intended to be so inflexible as to limit the economies of lower impact
development alternatives or other innovative or creative designs that could result in equivalent
or improved safety, quality, and maintainability. At the same time, environmental conditions may
requiie more limiiing design parameters than would be otherwise required bythese Standards.
Any proposed variance from the Standards will be evaluated as to the likelihood that such
variance will produce a compensating or comparable result as would the application of the
original standard under typical conditions and be safe and adequate for the public in every way.
fhe final decision on any proposed variances will be made by the Deputy Public Works Director/
City Engineer or his or her designee (hereinafter'Engineer').
This document does not require that existing facilities not subject to any public or private
development be rebuilt to comply with these Standards, but the Engineer reserves the rightto
require upgrades in any particular circumstances where warranted and as required by applicable
law.

GENERAL CONDITIONS AND REQUIREMENTS
GENERAL
These Standards are the general conditions and requirements for all improvements to or
extensions of the City of Kents street, storm drainage and utility systems.The conditions
as stated herein, and in the current City of Kent Surface Water Design Manual, apply to all
improvements made by public agencies, utilities, and private developers.
For the sake of efficiency, the term "Developer'means any person or entity designated
or named in writing by the property or easement owner to be the applicant, or a public
agency or utility which owns a right-of-way or easement in a permit application or
approval for a development proposal or capital improvement project. Developer also
includes a permit applicant, one who has already been granted a permit, and the City
itself for those situations where City construction activities are subject to approval under
the particular standard. While the City will be guided by the standards as noted herein,
the City does not grant or require permits or financial guarantees for its own work.
APPLICABILITY
These Standards shall apply to all newly constructed street, utility, and right-of-way
facilities and improvementS public and private, within the City of Kent.
The Standards apply to modifications of street features or existing facilities which are
within the scope of reconstruction, widening or narrowing, required off-site street
improvements for land developments, or capital improvement projects when so required
by the City, or to the extent they are expressly referred to in the Kent Comprehensive Plan
and associated subarea plans.
The Standards shall apply to every new placement and every planned, non-emergency
replacement of existing utility poles, underground facilities, and other utility system
structures within the City right-of-way. Every effort shall be made to meet the Standards
during emergency replacements.
SEVERABILITY
lf any part of these Standards as adopted by ordinance shall be found invalid, all other
parts shall remain in effect.
CHANGESTOTHIS MANUAL
The Engineer may incorporate minor changes to these Standards as they become
necessary. Major, substantive changes shall include an opportunity for public review and
comments and adoption by ordinance.
With a publication of this complexitythere may be errors that must be conected, and
periodic updates required due to changing standards.The City strives for accuracy and
consistency in these standards. Any errors, omissions or recommended changes may

CONSTRUCTION CONTROL AND I NSPECTION
BASIS FOR CONTROL OF THEWORK
Work performed in the construction or improvement of public or private streets and
utilities shall be done in accordance with these Standards and approved Engineering
Plans, and any other specifications or guidelines as per Section 1.6 References. lt is
emphasized that no work may be started until such plans are approved by the City.
Any revision to such Engineering Plans shall be approved by the Engineer before being
implemented per Section I .14 Revisions or Additions After Approvals. Any improvements
by other water and sewer providers other than the City shall be designed and approved
by the utility, with copies provided to the City prior to approval of the Engineering Plans.
The Engineer is authorized to enforce these Standards as well as other referenced
or pertinent specifications or guidelines. He/she will appoint project engineers and
inspectors as necessary to inspect the work and they will exercise such authoriry as the
Engineer may delegate.
Provisions of Section 1-05 of the WSDOT Standard Specifications shall apply, with the
term "Engineer"therein construed to be the Engineer as defined in these Standards.
INSPECTION
Generally, on all privately developed infrastructure including street, utiliry and drainage
system construction proposed or in progress by a private developer, control and
inspection will be done by the Construction Management Section on behalf of
the Engineer. The Engineer must approve any variances from the Standards during
construction as described herein.
The Developer is ultimately responsible for quality control of construction and the
assurance of meeting these Standards. Public Work inspectors monitor these activities
with enforcement authoritywhen requirements are not met.
All materials provided by the Developer shall be subject to inspection and approval
by the lnspector at any time during the progress of work until Final Acceptance.The
contractor's construction schedule shall include sufficient time for materials testing and
any required verifrcation by the lnspector.
The Inspector mayadvisethe Developerorcontractorof anyfaultyworkormaterials;
however, failure of the Inspector to advise the Developer or contractor does not
constitute acceptance or approval. Any deficiency list the lnspector may or may not
provide to the Developer prior to a formally scheduled final inspection event (Section
1.15.J and 2.2.A.t1),shall be viewed as assistance to the Developer, as aid for expeditious
and diligent completion of the work. ln no way shall periodic lists be required of the
lnspector or be construed as a final inspection document by the Developer. At the
lnspector's order, the Developer and/or contractor shall immediately remedy, remove,
replace, and dispose of unauthorized or defective work or materials and bear all the costs
of doing so.

All costs for re-testing, including the lnspector's time to come back due to the
Developer"not being readyi will be the responsibility of the Developer. Costs
shall include labor at overtime ratet overhead, equipment, material and any
other associated charges.The costs shall be based on the latest cost schedule
prepared and approved annually by the Engineer.
Chlorine lnjection
After the Contractor has cleaned the watermain by Cubing and flushing, the
Contractor shall inject a liquid chlorine solution evenly throughout the new
main and all connections and Appurtenances for complete and optimal
disinfection.The chlorine dosage shall be a minimum of 50 mg/l and a
maximum of 1 00 mg/l. AWWA C651 -99 Standards include detailed procedures
for the adequate disinfection, flushing and microbiologicaltesting of all
watermains. lf the contractor wishes the water section to do the injection,
the lnspector shall give theWater Section five (5)working days notification
to perform the chlorine injection.The Contractor must sign a waiver holding
the city harmless for any failure of purity samples due to the work performed
by the Water Section, as well as agreeing to reimburse the City for all costs
associated with the disinfection process. Work may be scheduled after
hours, outside of the 5-day notification period, or refused by the City due to
manpower or workload constraints.
The chlorine shall remain in the main for the time specified according to the
procedure used from AWWA Standards C651-99. After the 24-hour disinfection
period, the remaining residual throughout the watermain and Appurtenances
shall not be lower than 25 mg/L, if so it would require reapplication of chlorine.
The Contractor shall be responsible for disposing of all chlorinated and turbid
water. Chlorinated and turbid water shall be disposed of in an approved
sanitary sewer. lf a sanitary sewer is not available, or the capacity of the sanitary

Two (2) consecutive sets of acceptable puriry samples, taken at least 24 hours
apart, shall be collected from representative points of the new watermain, all
appurtenances and all other connections to the new watermain(s).
Water Section personnel will take the first bacteriological puriry sample(s)
after the chlorine is removed, flushing is completed and the chlorine level
is no greater than, or less than, the level present in the adjacent distribution
system.Water services installed prior to watermain testing shall also be purity
tested with the water main and all other connections to the new watermain.
The second set of purity samples shall be taken 24 hours after the first set of
samples. A representative background sample of the City water system may be
taken from the distribution source at the same time purity samples are taken
from the new main.
ln the event that the Water Section or the lnspector determines that trench
water, dirt or debris has entered the new main during construction, the first
purity samples shall not be taken until the water has stood in the new main for
at least 16 hours after final flushing. As above, the second set of purity samples
shall not be taken until the water in the new main has stood for an additional
24 hours.
No water shall be flushed during the 1 6- or 24-hour incubation periods
described above, or prior to the purity samples being taken.
It shall be the contractor's responsibility to make arrangements to transport
the sample(s)toTest Laboratories located at 13600 NE 126th Pl' Suite C,
Kirkland,WA 98034.The Contractor shall be responsible for paying all costs for

2071 DESIGN & CONSTRUCTION STANDARDS
PUBLIC WORKS DEPARTMENT
4.1
4.O STANDARDS FOR SANITARY SEWER SYSTEMS
These Standards contain the design criteria and improvement standards for the
extensions or connections to the City of Kent Sanitary Sewer System.The conditions
apply to all improvements made by both public agencies and private developers.These
improvements may include the following:
Sewer main extensiont modifications and replacements
. Side sewer connections to City mains
. Sewer Lift Stations
EASEMENTS AND RIG HTS.OF.WAY
Permanent on-site eaSements for acceSt maintenance, and construction are required
for all sanitary sewer extensions located outside of public right-of-way.Whenever an
easement or right-of-way is fenced, a gate shall be installed matching the width of the
easement and a City lock must be placed in'series"to facilitate access by the City. When
easements are required, legal descriptions shall be prepared by a Professional Land
Surveyor licensed bythe State ofWashington. A title report, dated within thirty (30) days,
for all properties to be encumbered by the easements shall accompany the description.
When off-site and/or on-site easements for the extension of approved comprehensive
sanitary sewer plans are required, these easements shall be approved and recorded by
the City before any civil construction permit is issued, unless the easements are being
dedicated to the City as a part of the final recorded subdivision.
private improvements such as buildingl fences, garages, carports, retaining walls, utilitiet
siqns, light fixtures, planting of large tree species, etc., are not allowed in public easements
and rights-of-way. Where an encroachment occurt the Contractor shall remove and
relocate the conflicting private improvement immediately upon direction from the
Engineer and restore the area to a condition compatible for the intended use of the
Easement by the City.
4.1.A EasementRequirements
Easements shall be accessible for construction equipment normally used
for the operation and maintenance of the facility. Cross slopes exceeding
5 percent will require a variance approval of the Engineer.The minimum
easement widths, centered on the utility system are as follows:
1. Sanitary Sewers 015'deeP: '15'wide
2. Sanitary Sewers 519'deeP: 25'wide
3. Sanitary Sewers over 9'deep -The formula for half of the width of the
4-1
EXHIBIT A
2O2T DESI GN & CONSTRUCTION STANDARD S
PU BLIC WORKS DEPARTM ENT
4.2
Easement shall be the sum of:the total depth from the top of pipe to the
surface plus the pipe diameter, plus 31The total will then be rounded to
the nearest even foot to a maximum of 5O'total width'
4. Special conditions or installation requirements may require greater
easement widths as determined by the Engineer.
5. ln easements with multiple utility systems, the easement width shall be
increased by the minimum separation distance between the lines.
4.1.8 Right-of-Way
Where possible, utilitysystem extensions shall be located within City rightof-
way.Work inside adjacent Cities, County and State rightof-way requires special
permits from the appropriate agencies. ciry county and state right-of-way
permits must be obtained by the Developer or the City if required by franchise
prior to Engineering Plans approval by the City.
PLAN APPROVAL AND PERMITS
The construction of sanitary sewer extensions within the City and approved franchise
service areas requires the approval of the City, DOE, and K?DNRP-WTD' No construction
shall be permitted untilthe Engineering Plans have been reviewed and approved by
these agencies. Said construction is also subject to Ciry permit and plan review fees.
Contact the Permit Center for a current fee schedule.
SANITARY SEWER SYSTEM DESIGN REQUIREMENTS
4.3.A General
All sanitary sewer systems shall conform to the design requirements of the
Criteria for sewageworls Design issued by DoE and thewsDoTStandard
Specifications as shown in Section 1 .6 References. All work shall comply with
the design requirements of K?DNRP-WTD when connections are made to
their system.
4.3.8 Comprehensive Sanitary Sewer Plan
The city has developed a comprehensive sanitary sewer plan to allow the
orderly and cost effective development of sewerage facilities to serve existing
and future users of the Kent sewer system.
The Comprehensive sanitary Sewer Plan includes a map of proposed sewer
extensions to service areas presently not served or under served by the City.
The plan shows the general location of interceptor and trunk sewert intended
to provide the framework of the collection system for the service area. All
proposed sewer improvements and extensions shall be consistent with the
Comprehensive Sanitary Sewer Plan,

P U BLIC WORKS DEPARTM ENT
4.4
4.3.C Service Area Considerations
All sewer extensions shall be designed for the ultimate development of the
service area in accordance with current land use plans.The determination
of the tributary area shall be based on the Comprehensive Sanitary Sewer
plan and detailed studies of the areas affected.The Engineer shall assist in the
determination of the tributary area and must approve the service area plan
prior to detailed design of the sewer system.
New sewer systems shall be designed on the basis of per capita flows or other
methods as approved bythe City and DOE detailed design calculations and

exceeds one (1) acre.The NPDES permit requires that a stormwater pollution prevention
plan (SWPPP) be developed for all projects covered. A Certified Erosion and Sediment
Control Lead shall be required to be onsite during construction. See the Department of
Ecology website at:
https//ecology.wa.gov/Regulations-Permits/Permits-certifications/Stormwater-general-
permits
See the KSWDM for allowable erosion control best management practices.
LOW IMPACT DEVELOPMENT TECH NOLOG IES
The City requires the use of Low lmpact Development (LlD) technologies per the current
KSWDM. LID is a stormwater management and land development strategy applied at
the parcel and subdivision scale that emphasizes conservation and use of existing natural
site features integrated with engineered small scale hydrologic controls to more closely
mimic pre-developmentfunctions.The goalof LID is to prevent measurable harm to
streams, lakes, wetlands, and other natural aquatic systems from residential, commercial,
and industrial development sites.
LID technologies include Stormwater best management practices designed to reduce
runoff from development using infi ltration, evapotranspiration, or stormwater reuse.
Examples of LID technologies include treet preservation of native vegetation, porous
pavement, bio+etention swales, infiltration systems, dry wells, cisterns, and rain gardens.
LID technologies proposed within the public right of way shall be approved by Public
Work Operations during the permit process before any civil construction permit is
issued.

STANDARDS FOR STREETS
RIGHTS.OF-WAY AN D EASEMENTS
Public streets are owned and maintained by the City, and the Developer is required
to dedicate or deed right-of-way, or otherwise convey public right-of-way and/
or easements, as required to construct and maintain these public streets and
appurtenances.
All portions of the traveled way, curbl gutters, sidewalk, medians, drainage facilities,
street lighting, traffic signals, roundabouts, tralfc circlet traffic signage and other required
improvements shall be located within said righrofway.
Easements for the purpose of construction, acces5 maintenance, sight distance
preservation, street slopes, street lighting, or for utility and storm drain system installations
may be required in conjunction with new street and street improvements.
A non-exclusive 10'utility and street lighting easement shall be provided by all private
development projects adjacent to all public streets except in the Downtown Overlay
District.
permanent on-site easements for accest maintenance, and construction are required for
all public and private street systems serving more than one property located outside of
public rightof-way.When easements are required,legal descriptions shall be submitted
pr.pur.d and stamped by a Professional Land Surveyor. A title report, dated within the
iast thirty (30) days, covering the properties to be encumbered by the easements, shall
accompany said descriPtion.
When off-site and/or on-site easements for the extension of public or private street,
water, sanitary sewer, storm drainage or other utility systems are required, these shall be
approved and recorded prior to approval of the Engineering Plans.The same conditions
shallalso apply regarding legal descriptions and title reports.
STREET TYPES AND GEOMETRICS
General design objectives and purpose by functional classification for City streets are
listed in the KentTransportation Master Plan (TMP). Based upon these classifications, the
criteria for right-of-way, street width and other Geometrics are established by the City.
TheTMP defines the following streets:
. Principal Arterial 7 - Lanes (See Standard Plan 6-2)
. Principal Arterial 5 - Lanes and Minor Arterial (See Standard Plan 6-3)
. collector Arterials - lndustrial Collector Arterial (See standard Plan 6-4)
6-1
EXHIBIT A
2021, DESIGN & CO NSTRUCTION STANDARDS
PU BLIC WORKS DEPARTMENT
. collector Arterials - Residential collector Arterial (See standard Plan 6-5)
. Collector - Residential Collector (See Standard Plan 6-6)
. Local Access Streets - Industrial/Commercial (See Standard Plan6-7)
Local Access Streets - Residential (See Standard Plans 6-1 1 through 13)
Local streets can be comprised of industrial/commercial streets and residential streets.
These streets are based on the land use zoning adjacent to the street. There are also
alleys and private streets.
Where appropriate and feasible, rights-of-way should be increased to accommodate
the use of low impact development and materials to handle storm water, including
landscaped medians facilitating natural storm water function and bio-filtration areas (rain
gardenl swales, etc).
6.2.A ArterialStreets
Arterials generally support higher traffic volumet much of which is generated
outside of the immediate area or what is termed "through trafficl'Arterials
support the travel of cars and trucks and other modes, including public transit,
cycling and walking.
Removal of existing driveways may be required if adequate access can be
provided by streets of a lower classification. ln some cases the combination
or consolidation of driveways from adjoining properties will be required with
shared aCceSS easements or tracts to meet access management standards'
Driveway access to minor arterial and collector arterial streets will be managed
to retain the traffic volume capacity of the roadway while allowing access to
parcels not served by streets of a lower classification. Existing driveways may
be required to be eliminated if adequate access can be provided by streets of a
lower classification.
6.2.8 Collector Streets
Collectors serve a critical role in the roadway network by gathering traffic from
local roads and funneling them to the arterial network. Collectors serve both
land access and traffic circulation in lower density residential and commercial/
industrial areas. They extend into residential neighborhoods. Collectors also
distribute and channeltrips between arterials and local streets and arterials.
6.2.C LocalStreets
These streets are designed for local traffic usage. They are typically the streets

in front of residential property and some commercial and retail uses.Two
subcategories of local street classifications exist based upon the type of
adjacent land-use.The sub-categories, and their functions, are:
1. lndustrial/commercial Street -These streets are designed to provide
direct access from the abutting industrial or commercial land uses to the
collector arterial classified streets. Access to these streets is typically not
restricted for reasons of safety except at or near intersections'
Residential Street -These streets are designed to provide direct access to
abuttinq land uses, from collector streets in a safe and efficient manner.
The design parameters ofthese streett (i.e., intersection spacing, horizontal
curves criteria, and right-of-way assignment at intersections) will be used
to minimize vehicle operating speeds and nonlocally generated'tut-
through'traffic. On-street parking will generally not be resiricted, except at
those locations necessary for public safety. A high emphasis will be placed
on safely accommodating non-motorized and pedestrian traffic in the
design of these streets.
Private streets fall within the residential street classifrcation. However, the
geometric requirements for private streets are different and can be found

street is available. On properties with multiple public street frontages, the
Ciry will restrict vehicular access solely to the public street having the lower
street classification, and/or to the safest access location. Retail, commercial
or industrial driveways shall be prohibited from access to residentialstreets.
Coordinated access (via cross access, joint or reciprocal access agreements
recorded with the CountyAuditor's office)with adjacent properties may
be required of the Developer, where driveways are located on arterials
and collectors or driveway separation and corner clearances cannot be
achieved.

according to the requirements of these Standards. See Standard Plans 6-64 through 6-69.
When an existing asphalt pavement is used, the Developer shall remove by saw cut at
least the outer 1'of the existing asphalt pavement to provide a strong and straight edge
for the new asphalt to match.The actual outside line for this asphalt pavement removal
will be determined on-site by the Engineer to ensure that all inadequate and failing
pavement is removed.
When an asphalt overlay occurs adjacent to an existing concrete curb and gutter, the
Developer is required to install the new asphalt pavementflush with the existing curb
and gutter. The Developer will do this by cold milling (grinding) a minimum 4'wide strip
of pavement immediately abutting the concrete curb and gutter.The minimum depth
of this grinding shall be 2'and shall leave a minimum 2'of existing pavement in place.
Should there be less than 2"of remaining asphalt pavement, the Developer shall remove
and replace the outer 4of asphalt pavement.
When the surface of the existing street pavement is determined, by the Engineer, to be
too rough or irregular, the Developer shall provide an asphalt overlay, cold milling, or a
combinition of the twg to provide an acceptable riding surface for the improved public
street.

Pavement Design
See the Standard Plans for detailed pavement design information and
minimum pavement sections. Portland cement concrete streets may be
considered as an acceptable alternative to asphalt concrete streets for most
street classifications. Specific approval by the Engineer is required prior to
design of concrete streets.
Porous pavements may also be considered for low traffic volume private
residential streets and driveways. Porous pavement is a permeable paving
material which allows stormwater to percolate through the pavement to
the gravel base.The pavement consists of a uniform, open-graded coarse
aggregate, cemented together with either concrete or asphalt. Water reaching
the gravel base either infiltrates into the soil or is routed to the conveyance
systems via underdrains.The Developer must sign a maintenance agreement
with the City confirming that the development will be required to bi-annually
vacuum sweep the pavement surface followed by a high pressure wash'
Pavement Construction
All pavement construction shall be in accordance with the WSDOT Standard
Specifications except as modified herein.
When asphalt concrete is placed in lifts, tack coat in accordance with the
wsDoT standard specifications shall be used unless the lifts are placed on the
same day, and approved by the Engineer.

onto a wvo-lane roadwaywith grades of 3 percent or less.The time gap used in calculation
of the right turn sight distance is 6.5 seconds. For other conditions the time 9ap must be
adjusted and required sight distance re-calculated. (See AASHTO'A Policy on Geometric
Design of Highways and Streets').
'l 3. lntersection/driveway sight distance shown is for a stopped passenger vehicle to turn left
onto a two-lane roadway with no median and grades of 3 percent or less.The time gap
used in calculation of the left-turn sight distance is 7.5 seconds. For other conditions the time
gap must be adjusted and required sight distance re-calculated. (See AASHTOA Policy on
Geometric Design of Highways and Streets').
,14. On multi-lane roadways: For left-turns onto a two-way roadways with more than two (2)
lanes, add 0.5 seconds for passenger cars and 0.7 seconds for trucks to the time gap for each
additional lane from the left, in excess of one, to be crossed by the turning vehicle'
,l5. The rate of vertical curvature'Kvalue derived from the length of vertical curve per percent
change in the algebraic diflerence of the adjacent grades are based on design values listed
in AASHTO'5? Policy on Geometric Design of Highways and Streetsj'AKA"The Green Bookj'
latest edition.
'16. The AASHTO'passenger comfort curve'for sag curve design, where the length of the sag
curve is determined by the equation below is an acceptable alternative if adequate

required streettree plans associated with public street improvements.
There are many site constraints that may limit the species of street trees that can be planted in a specific
location.The following are typical site constraints and/or standards that are associated with an urban
street tree planting environment, and that must be considered before the City gives approval to plant a
specific street tree species for a particular prolect:
1. Sidewalkwidth
2. Rooting space (tree pit size, planting strip width)
3. Building setbaclc (distances from trees)
4. Canopy or Building overhang (distances from trees)
5. Signs,Windows or Entryways (placement, size, use, safe$
6. Street Lightin g and/or Pedestrian Scale Lighting
7. Soils
B. Pedestrian Clearance
g. Presence of Underground and Overhead Utilities
10. StreetTree (root and crown groMh, maintenance, aesthetics, etc.)
1 1. Vehicle Parking
12. Horizontal and Vertical Sight Distance Clearance
13. City of Kent Construction Standards

BACKGROUND
ln I ggg, the city of Kent adopted The Downtown Plan that envisioned the small traditional
downtown shopping district would transform into a vibrant pedestrian-friendly mixed-
use center.The Downtown PIan was later updated in 2005 to become the Downtown
Strategic Action Plan; it addressed the influences of high-capacity commuter rail serving the
community. In 2013, the Downtown Subarea Action Plan (DSAP)expanded the Downtown
planning Aiea west of SR-l 67 and north of James Street up CentralAvenue, creating a need
to update the 2003 Downtown Design Review Guidelines.
The intent of the Downtown Design Guidelines is to establish a consensus of quality, unity and
conformity. The design elements and guidelines reflect the DSAP's vision for Downtown
Kent as a livable, vibrant, pedestrian-friendly mixed-use community that complements transit
with olfice, commercial and residential uses clustered in the urban center. This vision for a
vital downtown is consistent with regional growth strategies and the City's Comprehensive
plan. The DSAP'5 Planning Principles influence the goals of the Downtown Design Guidelines
to create a memorable, extraordinary place, where the pedestrian is first in this livable,
economically vital, and gracious downtown that is the'Heart of Kent'i
This document incorporates the original design criteria and is updated to be applicable to the
expanded Downtown Area.When a new development or a remodelof an existing building
is proposed, the City will apply the design guidelines to accomplish the following goals:
DOWNTOWN DESIGN GUIDETINES GOATS
. Build a desirable place to live with a variety of housing choices,
convenient services, and a diversity of entertainment opportunities;
. Support a pedestrian-oriented environment that connects to
surrounding neigh borhoods;
. Create a memorable downtown experience that is attractive, safe,
and inviting;
. Construct a visually attractive and economically vibrant urban center;
. Assure new development relates to the character of downtown and is
compatible with surrounding neighborhoods;
. Ensure public and private outdoor spaces are enjoyable and
accessible; and
. Encourage sustainable building and land management best practices

APPTICATION OF DESIGN GUIDETINES
The Downtown Design Guidelines apply to the Downtown Area (see Figure 1) bounded by 64th
Avenue South to the west; north of James Street and up Central Avenue to approximately South 234th
Street; Kennebeck, Clark, Jason, and Titus to the east; and Willis Street to the south. The guidelines are
applicable to all of the Downtown Area, while other guidelines apply only to particular pedestrian
designated streets found in the Pedestrian Plan Overly map.
All development within the Downtown Commercial (DC), Downtown Commercial Enterprlse (DCE),
and that portion of the General Commercial (GC), General Commercial Mixed Use (GC-MU), and
Multifamily ResidentialTownhouse (MRT-16) zoning districts located within the Downtown Area (see
Figure 1), is required to meet the requirements of downtown design review (KCC 15.09.046) Downtown
d&ign review is conducted by an administrative committee, except for modifications of existing build-
ingsind sites that cost less tl-ran 5100,000, which are reviewed by Planning Services stafL The scope of
work associated with an individual project will determine the extent to which design guidelines will be
applied. Proposals that will not modifu a building exterior or the site are exempt from design review

PURPOSE OF DESIGN GUIDETINES
The purpose of the guidelines is to create site and building designs consistent with the DSAP's Planning
principles, Goals anJ Policies. The document is organized by design guideline topics into the Site Design
and Building Design sections. Each section contains guidelines dealing with specific topics.The Definitions
section will help the applicant understand design and architectural terminology
The Downtown Design Guidelines set parameters for design, but also allow design flexibility and creative
design solutions. proposed development in the Downtown Area is expected to respond to the following
desi!n guidelines and standards in a manner that promotes a lively and vibrant pedestrian-oriented
urOan neigf'Oorhood, supports multiple modes of transportation including bicycling, and complements
Kent's Historic District (DC zoning district).
This manual is easy to use. Each guideline starts with an objective that explains the desired outcome
of each guideline and often provides a description and illustration to help the user apply the concepts.
Guidelines that use the word "should"or"may"can be satisfied from a variety of listed design options or
by equal or better means if it can be demonstrated satisfactorily to the Planning Director that the
applicant satisfies the intent of the guidelines. Standards that use the word "shall" must be met. The
grid.lin., place a minimum burden on projects, and most importantly, the guidelines do not inhibit
creative design.
The City may permit a deviation from a specific standard if it is determined that public benefit may be
achieved by an alternative proposal. The alternative proposal must be consistent with the intent of the
guidelines and with the Comprehensive Plan Goals and Policies. The applicant must demonstrate that
ihe proposed devlation will result in increased pedestrian activity and visual interest along the street
DESIGN REUIEW PROCESS
Before preparing development plans in the Downtown Area, applicants should review the guidelines
and use the Downtown Design Guidelines Checklist to determine which guidelines apply to their
proposed project. Planning Services staffwill discuss guidelines and standards with the applicant either
during a pre-ipplication meeting or informal pre-development design meeting in order to assist the
applicant with final design approval.
For details on the application and review process, see Kent City Code 15.09.046; if you have questions,
staff with Planning Services are available to assist you

I. SITE DESIGN
Site design is the arrangement of buildings, landscaping, plazas, circulation elements, and other
features in response to unique site features and surrounding context. A well-designed site should
function with sensitivity to safety, aesthetics, and comfort for all users.
A. STREET RETATIONSHIP
INTENN
To create a streetscape that is active, safe, convenient, comfortable and appealing for people on foot to
connect to work places, parks, schools, shopping and transit facilities
GUIDELINES:
1. Pedestrian Plan OverlaY:
The pedestrian plan Overlay classifies certain streets downtown as Class A and Class B pedestrian streets
The objective is that development located adjacent to these streets meets a high standard for achievlng
a successful pedestrian-oriented environment. The Pedestrian Plan Overlay determines, on a block-by-
block basis, the character of street frontage and level of pedestrian amenity. li in the future, new streets
are developed on large parcels of downtown land, the new streets should be designated according to
planned pedestrian usage before development permits are approved
The street designations are defined and illustrated on the Pedestrian Plan Overlay map (see Figure 2),
followed by the design guidelines for Class A and Class B streets

Class A streets are intended to accommodate and foster the greatest pedestrian usage by providing a high
degree of comfort and safety through streetscape design and minimization of vehicle-pedestrian conflict
points. The following guidelines apply to a Class A street:
(1) A continuous building wall should be maintained along the entire property frontage abutting a Class
A street.
(2) Curb cuts through a continuous building wall are restricted and should be permitted only when
there is no alternative property frontage.
(3) No surface parking areas should abut a Class A street unless there is no alternative property frontage.
(4) pedestrian access into or through the site is allowed to break the continuous building wall.
b. Class B Street:
Class B streets are intended to reinforce an active pedestrian-oriented experience, but also accommodate
vehicular access to the site. The following guidelines apply to a Class B street:
(1)A continuous building wall should be maintained for a minimum of 50% of the property frontage
abutting a Class B street.
(2) Curb cuts within the remaining 500/o of the property are permltted from a Class B street.
(3) Surface parking areas may front on a Class B street only within the remaining 50% of the property'
(4) Surface parking areas shall not be allowed in front of the buildlng'

An exception to allow i maximum 2O ioot setback is permitted if a pedestrian activity is planned for that
space, such as an entry, pedestrian plaza, outdoor dining, or a garden space associated with residences
(see section 1.A.5.a. for setback provisions for corner buildings). The applicant may propose a greater
setback to provide greater pedestrian interest and activity subject to approval by the city. The block
within the Historic District is not eligible for exceptions.
('t)The building setback is measured from the outside edge (closest to the building) of the
required sidewalk.
(2)The building setback can be applied to the entire building facade adjacent to the street corner or can
be applied io only the first level of a multi-story buildlng with the upper levels cantilevered over the
first level. Vertical height of the overhead clearance for the ceiling of a pedestrian area or pathway
under a cantilevered second level of a building shall not be less than 12 feet.
b. Public DeveloPment ExcePtion:
An exception may be made for Public
space adjacent to a public building if the
intent and standards ofthe pedestrian-
oriented street front section (see section
l.B.) are met.The setback area may not be
used for parking.

C. SITING AND SCREENING OF SERUICE AND PARKING FACITITIES
INTENN
To diminish and soften the visual impact of asphalt and parked cars from the street and adjacent properties,
reduce the visibility of unsightly but necessary activities (trash containers, for example), and to allow for
infiltration of storm water run-off.
GUIDELINES:
1 . lncompatible activities:
The objectlve is to minimize the impact of incompatible activities on adjacent uses. lncompatible actlvities
include: outdoor storage (where permitted), service areas adjacent to other uses, public and private utilities
apparatus, and commercial development contiguous with a residential-zoned property Design standards for
such incompatible activities are as follows:
a. Locate incompatible activities, including allowed outdoor storage in the GC zone, away from
neighboring properties to reduce visual impacts and physical conflicts.
b. Where the City deems necessary, landscape buflers or another form of screening shall be provided
along property lines adjacent to incompatible uses. When topography between the activities is
sufficient to reduce impacts, then modification to the buffer options may be allowed.
c. lntegrate outdoor storage areas, utilities and loading facilities into the site design in a manner that
reduces visual impact and obstruction of pedestrian and vehicular movement.
d. Whenever feasible, locate or screen public/private utility apparatus (i.e., electrical conduit and utilities
equipment and apparatus) so as not to be visible from the street or adjacent properties.
e. Locate or screen roof-mounted mechanical equipment so that it blends with the architecture of the
building and is not visible from the street or adjacent properties'
f. Buffers or fences of outdoor storage and service areas (i.e. large waste containers) must conform to the
requirements of the City of Kent Zoning Code as a minimum standard. Additional buffer area or screening
may be required.
2. Parking lot facilities:
The objective ll to coordinate parking lot facilities to reduce visual lmpacts as follows:
a. ln parking lots, the preferred location for markings and signs for individual stalls is the pavement. Limit
the heiglit of free standing or wall mounted stall signs to two (2) feet above grade, except for handicap
accessible parking signs, which shall be placed perADA standards
b. Limit parking lot entrance signs to one (1 ) per parking area entrance. The sign sha ll be no more than six
(6) feet in helght above grade, and shall have a surface area of no more than six (6) square feet per side.
The sign may not be internally lit, but may incorporate neon lights'
c. Screen all moveable parking lot equipment (i.e., barrels, saw horses, etc.) from the public right-of-way.
d. The size and surface area of required parking lots should be mlnimized by the following:
(l ) Share parking facilities whenever feasible under the joint use parking standards of KCC
15.05.0a0 (c);

D. SITE DESIGN FOR SAFETY
INTENT:
To promote personal safety and property security through design of site features including lighting,
landscaping and building design.
GUIDELINES:
1. Pedestrian safety:
The objective is to ensure pedestrian safety by minimizing conflicts
between drivers and pedestrians through the siting of structures, location of
circulation elements, landscape design, and placement of signs. lncorporate
the following methods for protecting pedestrian safety, where appropriate:
a. Limit the number of potential encounters between pedestrians and
vehicles through site design.
b. Where pedestrian and motorist paths must cross, ensure visibility of pedestrians and vehicles.
c. Within parking lots, provide raised pedestrian walkways where possible. Where not possible, provide
at-grade walkways protected by curbs or landscaped areas
d. Distinctively mark pedestrian routes through parking lots. Use vertical design elements, or special
paving suc-h as brick, concrete, oi cobblestone. lnclude pedesirian amenities such as benches, trash
contalners, and planters whenever possible.
e. Separate service vehicle access and loading zones from pedestrian areas.
f. Use on,site directional signs to clearly mark pedestrian and vehicular routes.
2. Eyes on the street:
The o-b.lective is to provlde surveillance opportunities from buildings and
public streets to discourage anti-social activity. lncorporate the following
methods to increase personal safety and security, where appropriate:
a. Avoid site design features that create entrapment areas such as long,
dark enclosed corridors and opaque fences in locations with
pedestrian activitY.
b. Ensure that site and building designs provide lines of sight that allow
building occupants and passersby to observe on-site and street
activities for the purpose of informal surveillance (i.e., windows,
balconies, entries, etc.).

As used in these guidelines, the front yard is the area between the street(s) and the nearest building fagade
Gateways
As used in these guidelines, the term gateways refers to key intersections within the city which are
entranceways into the Kent downtown area, The gateways will be enhanced by special sidewalk/crosswalk
treatments, landscaping, signage, lighting, banners and other improvements to signify their staius as entryways
into the downtown core.
Historic District
The Historic District is the traditional and geographic heart of downtown Kent, containing the original business
district.The boundaries of the Historic District are Second Avenue to the west, Meeker Street to the north, E Titus
Street to the south, and the Railroad tracts to the east.The area is shown in Fig.3 on Page 17
Human Scale
The size of a building element or space relative to the dimensions and proportions of a human being
lncompatible Uses and Activities
As used in these guidelines, incompatible uses are those uses, including, but not limited to, outdoor storage,
utilities equipmenl and apparatus, and loading and service facilities, which are considered to be visually
intrusive, unsightly and which require site design and screening to mitigate the negative impacts to downtown
retail commercial, residential development, and surrounding residential zoning districts.
Lumen
A lumen is a unit used for measuring the amount of light energy given off by a light source'
Modulation
Modulation is a stepping back or projecting forward of portions of a building fagade within specified intervals
of building width and depth as a means of breaking up the apparent bulk of a structure's continuous exterior
walls, As used in these guidelines, the moduiated portions must be at least 6 feet deep in order to qualify as
modulation.
Pedestrian-Oriented Faqades
'pedestrian oriented'fagad.r ,ru those that contribute to the character of the street experience providing
pedestrian interest, comfort, and safety.
Pedestrian-oriented SPace
A pedestrian oriented space is an area between a building and a public street that promotes visual and
pedestrian access onto the site and that provides pedestrian oriented amenities and landscaping to enhance
the public's use of the sPace.
Pedestrian-oriented Use
A pedestrian oriented use is a commercial use whose customers arrive on foot, or where signage, advertising,

Service areas refer to areas, enclosed or open, that contain equipment and uses such as ground level mechanical
equipment, utility vaults, loading zones, outdoor storage areas, and trash and recycling areas.
Site Planning
Site planning is the arrangement of buildings, driveways, sidewalks, landscaping, parking, public open spaces,
and other faiilities on a sfiecific site. Good site planning will result in a cohesive site design concept and take
into consideration natural features, topography, drainage requirements, access points, the design of
neighboring sites, and other features in the immediate vicinity of the site.
Streetscape
The streetscape is the visualcharacter and qualityof a street as determined byvarious elements located between
the edge of the street and the building face, such as trees and other landscaping, street furniture, artwork, transit
stops, Jtility fixtures and equipment, ind paving. Where there are frequent and wide spaces between buildings,
the streetscape will be defined by the pattern of building and open space and the character ofthat open space.
Surface Parking
Surface parking is single level vehicular parking on the surface of the ground, generally a parking lot that
typically is uncovered.
Structured Parking
Structured parking is a multiple level vehicular parking facility, generally a parking garage or similar structure
constructed for that PUrpose.
Transit-oriented DeveloPment
Transit-oriented development (TOD) is development that is centered around and coordinated in its use
and design with a transit station or other transit facility.Transit-oriented development includes a variety of
different"planning and development projects, but is typically compact, medium to high density, mixed-use
development within walking distance of transit with a focus on pedestrian orientation and creating
neighborhood centers, places and/ or gathering spots.
