CODE REQUIREMENTS
WATER
1. The proposed water main improvements as shown on the composite utility civil plan submitted
with the Land Use Application provides the required 8-inch water main extension into the
development, connecting to the existing 8-inch water main located in S 132nd Street and the
existing 8-inch water main located in Renton Ave S. Renton Fire Authority has determined that
the preliminary fire flow demand for the proposed development is 1,750 gpm, with the use of
one-hour rated construction and approved fire sprinklers, which is greater than the available
maximum fire flow capacity.
2. The following water main improvements are required to provide water service for domestic use
and fire protection for the development per City Code and Development standards (RMC 4-6-
010B) including, but not limited to:
a. Extension of approximately 380 feet of 8-inch water main in Renton Ave S from S 130th
Street to a point which allow connection into the new water main for the development.
A 15-foot water easement will be required for any water main not located within the
public right-of-way.
b. Installation of 8-inch water mains in the new primary access roadway and alley sections
within the subdivision connecting to the new 8-inch water main in Renton Ave S and to
the existing 8-inch water main in S 132nd Street. Maximum capacity from the new 8-inch
main extension is 2,500 gpm.
c. Installation of fire hydrants as required by Renton Fire Prevention. The number and
location of the hydrants shall be determined based on the City’s review of the final
building and site plans.
d. Installation of a residential fire sprinkler system for each townhome unit with a double
check valve assembly (DDCVA) for backflow prevention on the water supply line to the
fire sprinkler piping.
e. Installation of a domestic water meter to each townhome unit with a double check valve
assembly (DCVA) behind the meter for townhomes with 3 or more stories.
f. A pressure-reducing-valve (PRV) is required behind each water meter because the water
pressure is over 80 psi.
3. Meter sizing shall be based on Uniform Plumbing Code meter sizing criteria. Sizing calculations
shall be provided to the City.
4. A separate meter is required for landscape irrigation per COR Standard Plan 320.1. A double check
valve assembly (DCVA) is required behind the meter per COR Standard Plan 340.8.
5. Please refer to City of Renton General Design and Construction Standards for Water Main
Extensions as shown in Appendix J of the City’s 2012 Water System Plan.
6. Adequate horizontal and vertical separation between the new water main and other utilities
(storm sewer pipes and vaults, sanitary sewer, power, gas, electrical) shall be provided for the
operation and maintenance of the water main. Based on the preliminary utilities plan submitted
with the land use application (reference civil plan by ESM, page PP-05 dated 3/27/17), the
horizontal separation between the proposed water mains and the proposed storm drains in the
alley sections does not meet the minimum 10-feet separation between parallel potable water and
non-potable water pipes. The vertical separation between the pipes is less than the minimum of
18-inches. Additional and special design and construction considerations will be required to
protect the water lines and to reduce risk to public health and safety. Restrained-joint water pipes

1-inch meters. This is payable at issuance of the building permit.
11. Additional water system development charges and water meter charges will apply if a landscape
irrigation meter is required and is based on the size of the meter.
SEWER
1. The proposed sewer main improvements as shown on the composite utility civil plan submitted
with the Land Use Application provides the required 8-inch sewer main extension from the
existing sewer main located in S 132nd Street and extending into Renton Avenue South for future
extension by the City. The required extension of the new 8-inch sewer main from S 132nd Street
into the future public ROW is shown on the conceptual utilities plan and provides the required
sanitary sewer service to each building.
a. A 15-foot public sewer easement shall be provided for the extension of the sewer main
through the stormwater tract for any portion of the extension located outside of the
public ROW.
2. The development is subject to applicable wastewater system development charges based on the
size of the new domestic water to serve the project.

The current sewer fee for a 1-inch meter is $2,540.00 per meter.
b. SDC fees are payable at construction permit issuance.
3. The S 132nd Street Sewer Extension Special Assessment District fee (SAD) fee will be applicable on
the project. The SAD fee rate when it was established in 2015 was $11,254.92 plus interest per
lot with frontage along S 132nd Street. As of 4/25/2017, the SAD fee rate per lot is $11,828.95
plus additional interest per day of $0.80 after the date noted above. The rate that will be
applicable on the issuance day of the utility construction permit will be applicable on this project.
As currently designed, there are 13 lots applicable to the SAD fee, however the maximum
assessment will be for 12 lots.
SURFACE WATER
1. A geotechnical report, dated January 18, 2017, completed by Associated Earth Sciences,
Incorporated (AESI) for the site has been provided. The submitted report describes the site is a
Earlington Townhomes – LUA17-000169
Page 4 of 8
Low, Medium, and High Erosion Hazard areas. Erosion control measures will need to be in place
prior to starting grading activities on the site. The report discusses the soil and groundwater
characteristics of the site including infiltration potential and provide recommendations for project
design and construction. The report discounts the use of infiltration due to the shallow site soils
that are either dense and impermeable or saturated. Geotechnical recommendations presented
need to be address within the project plans.
2. A Preliminary Drainage Plan and Technical Information Report (TIR), dated March 27, 2017, was
submitted by ESM Consulting Enginerrs, LLC with the Land Use Application. Based on the City of
Renton’s flow control map, the site falls within the Flow Control Duration Standard area matching
Forested Site Conditions and is within the West Lake Washington Drainage Basin. The
development is subject to Full Drainage Review in accordance with the 2017 Renton Surface
Water Design Manual (RSWDM). All nine core requirements and the six special requirements must
be discussed in the Technical Information Report. The following stormwater improvements are
required and shall be discussed within the TIR:
a. Applicant shall include discussion of Special Requirement (SR) #6 in the final drainage
report. SR #6 relates to the aquifer protection area, which is not applicable to this site,
but it should be noted as such in the report.
b. The TIR references the 2016 King County Surface Water Design Manual and the City of
Renton Amendments to the SWDM. The City has adopted the 2017 Renton Surface
Water Design Manual rather than providing amendments to the 2016 King County
SWDM. The final TIR submitted with the Civil Construction Permit Application shall
reference the 2017 Renton Surface Water Design Manual (RSWDM).
c. An infiltration testing report shall be submitted with the civil construction permit
application following the test methods outlined in the manual. See Section 5.2 and
Reference Section 6-A for approved testing methods.
3. The development is required to provide flow control and basic water quality treatment prior to
discharge. A detention vault is proposed to meet the flow control facility requirement to satisfy
Core Requirement #3. The detention pond has been sized to the City’s Flow Control Duration
Standard using WWHM. The project matches the pre-developed discharge rates from 50% of the
2-year peak flow up to the full 50-year peak flow and peak discharge rates for the 2 and 10-year
return periods as required in the City’s Flow Control Duration Standard (Forested Site Conditions)
area. Project water quality treatment will consist of conveyance to a water quality filter vault
following the proposed detention vault prior to connection to the existing 12-inch concrete
stormwater main located S 132nd Street.
a. The conveyance and water quality systems shall be designed in accordance with the
RSWDM that is current at the time of civil construction permit application.
b. A maintenance access road is required to the stormwater facilities in the proposed storm
tract and shall be in accordance with the design requirements outlined in the RSWDM.
4. Any proposed detention and/or water quality vault shall be designed in accordance with the
RSWDM that is current at the time of civil construction permit application. Separate structural
plans will be required to be submitted for review and approval under a separate building permit
for the detention and/or water quality vault. Special inspection from the building department is
required.
5. Appropriate on-site BMPs will be required to help mitigate the new runoff created by this
development. A preliminary drainage plan, including the application of on-site BMPs, has been
included with the land use application. The final drainage plan and drainage report must be
submitted with the civil construction permit application.
Earlington Townhomes – LUA17-000169
Page 5 of 8
a. The final drainage plan shall evaluate the feasibility of utilizing on-site BMPs to mitigate
all target impervious areas to the maximum extent feasible as outlined in the RSWDM.
This shall include infiltration testing to determine the feasibility of utilizing permeable
pavements and bioretention areas.
6. The site contains regulated slopes across the site with an elevation change of approximately 72-
feet from the northwest corner (approximate elevation 306 feet) to the low point of the property
near the southeast corner (approximate elevation 234 feet).
7. Detailed plans for any proposed cut and fill operations shall be submitted. These plans shall
include the angle of slope, contours, compaction and retaining walls.
8. Maximum exposed retaining wall height is 6-ft and shall be setback a minimum of 3-ft from the
right-of-way. Based on the site topography, terraced retaining walls may be needed for the
development. Retaining walls over 4-feet in height from footing require a separate building
permit.
a. The proposed development includes an 8-ft wall along Renton Ave S. The applicant will
be required to reduce the height of the proposed wall to the maximum 6 -ft allowed by
code. The civil construction plans shall fully detail the proposed retaining wall abutting
the public ROW. A handrail and/or fence may be required at the top of the wall.
9. All work proposed outside of the applicant’s property will require a permanent drainage
easement to be provided to the City and a temporary construction easement prior to any permits
being issued.
10. A Construction Stormwater General Permit from Department of Ecology will be required since
grading and clearing of the site exceeds one acre. A Stormwater Pollution Prevention Plan
(SWPPP) is required for this site.
11. Surface water system development fee is $1,608 per new dwelling unit. This is payable prior to
issuance of the construction permit.
TRANSPORTATION
1. The proposed development fronts Renton Ave S along the east property lines. To meet the City’s
complete street standards for minor arterial streets, minimum ROW is 91 feet (4 lanes) or 103
feet (5 lanes). The traffic analysis provided by the developer has been reviewed by the City and
the City concurs that the existing pavement width is sufficient and additional lanes are not
required as a result of the development.
a. The City’s transportation group has determined and will support an alternate standard
to match the established standard street section for Renton Ave S. The City established
standard street section for Renton Ave S, which shall be installed by the developer as
part of the proposed development, will allow the existing curb line to be maintained
with a new 8-ft planter strip and 8-ft sidewalk to be installed behind the curb. The final
ROW dedication will be dependent upon the final survey and will vary along Renton Ave
S. The required ROW behind the existing curb is 18-ft (8-ft planter strip, 8-ft sidewalk, 2-
ft behind the curb).
b. The bike lanes included in the street section for Renton Ave shown on the site plans (PP-
05) are not needed. Currently, the Renton Trails and Bicycle Master Plan specify a
separate combined bike/pedestrian path parallel to Renton Ave to provide bike access
for the Renton Ave corridor.
c. Applicant will need to submit an application to the City requesting a modification of the
street frontage improvements as outline in City code 4-9-250C5d.

2. The proposed development fronts S 132nd Street along the south property lines. To meet the City’s
complete street standards for collector arterial streets, minimum ROW is 83 feet (2 lanes) or 94
feet (3 lanes). The traffic analysis provided by the developer has been reviewed by the City and
the City concurs that the existing pavement width is sufficient and additional lanes are not
required as a result of the development. The required street section for S 132nd Street as proposed
by the applicant meets the minimum street standards as outlined in RMC 4-6-060F includes 83-ft
of ROW, 46-ft paved roadway width (two 10-ft travel lanes, 5-ft bike lanes and 8-ft parking lanes
on both sides), a new 0.5-foot curb and gutter, an 8-foot planting strip, an 8-foot sidewalk, street
trees and storm drainage improvements on both sides.
a. Half-street improvements, which shall be installed by the developer, along S 132nd Street
shall include, 23-ft paved roadway width from centerline (10-ft travel lane, 5-ft bike lane
and 8-ft parking lane), a new 0.5-foot curb and gutter, an 8-foot planting strip, an 8-
foot sidewalk, street trees and storm drainage improvements.
3. The applicant has submitted an application to the City requesting a modification of the street
frontage improvements. The development proposes installation of a new public residential access
road (Road A) with 29 feet of right-of-way, which includes 28 feet of paved roadway width, 0.5-ft
curb and gutter on both sides, private 4.5-ft planter strips on the east side of the street and private
5-ft sidewalks on both sides of the street. The proposed street section does not meet the
minimum street standards in accordance with RMC 4-6-060F and is not supported by the City.
a. The new public street for the development shall meet the minimum street standards as
outlined in RMC 4-6-060F. Minimum standards for a residential access road requires a
53-ft right-of-way, 26-ft pavement width, 0.5-ft curb and gutter, 8-ft planter strips and
5-ft sidewalks on both sides of the street.
4. Current City of Renton standards require a turnaround for dead-end streets greater than 150 feet.
Dead-end streets exceeding 300-feet must utilize a cul-de-sac meeting the requirements for
emergency services access, including a 45-foot paved radius and 55-ft ROW radius. Reference
RMC 4-6-060H. The cul-de-sac shall have a design approved by the Administrator and Fire and
Emergency Services.
5. Five alleys (Tracts A, B, C, D, and E), each with a pavement width of 20-ft, are proposed to provide
access to each unit.
a. Driveway aprons shall be installed at the entrance to each alley tract in accordance with
the City of Renton Standard Plans 104.2 and 104.3.
b. No parking is allowed within the 20-ft paved roadway of the alleys.
6. Corner lots on Minor Arterial and Collector Arterial Streets require a minimum radius of 35 feet
for dedication of right of way.
7. ADA access ramps shall be installed at all street crossings. Ramps shall be shown at each
intersection. Ramps shall be oriented to provide direct pedestrian crossings.
a. ADA ramps shall be installed facing east and west at the crossing of Road A along the
frontage of S 132nd Street.
b. ADA ramps shall be installed at the intersection of South 132nd Street and Renton
Avenue South with a companion ramp for the existing sidewalk on the south side of
intersection. Because of the steep grade on South 132nd Street and possibly steep grade
of the new sidewalk to be installed as part of the development, a pass through may be
needed in the existing paved island for access between the new curb ramp to be
installed at the northeast corner of the intersection and the new curb ramp on the south
side of South 132nd Street.

8. Street lighting and street trees are required to meet current city standards. Lighting plans were
not submitted with the land use application and shall be submitted with the civil construction
permit application.
9. A traffic analysis dated December 14, 2016, was provided by Northwest Traffic Experts (TraffEx).
The site generated traffic volumes were calculated using data from the Institute of Transportation
Engineers (ITE) Trip Generation Manual, 9th Edition, (2009). Based on the calculations provided
and providing credit for the existing trips utilized for the current site use, the proposed
development would generate approximately 292 net new average weekday daily trips. During the
weekday AM peak hour, the project would generate approximately 26 net new trips (5 inbound
and 21 outbound). During the weekday PM peak hour, the project would generate approximately
30 net new trips (20 inbound and 10 outbound). As detailed in the report the proposed project is
not expected to lower the levels of service of the surrounding intersections included in the traffic
study. Increased traffic created by the development will be mitigated by payment of
transportation impact fees.
a. The traffic analysis analyzed the new site access intersection (Road A and S 132nd Street)
and the intersection of Renton Ave S and S 132nd Street to the east of the proposed
development.
b. Renton Ave S and S 132nd Street both have posted speed limits of 35 miles per hour (MPH).
The required stopping sight distance and intersection sight distance for the posted speed
limit is 250-ft and 390-ft, respectively, per the current AASHTO “Geometric Design of
Highways and Streets” standards. As designed, the stopping sight distance and
intersection sight distance exceeds 500-ft both to the east and west directions from the
site access location.
c. The proposed development provides pedestrian connectivity through the development
via a series of concrete walkways through the open space tract at the north side of the
property and connecting to the proposed sidewalk along Renton Ave S.
i. At least one pedestrian connection to Renton Avenue South shall be ADA
accessible.
ii. An additional pedestrian connection shall be provided in the vicinity of Alley TR-
D or through Tract I.
10. Refer to City code 4-4-080 regarding driveway regulations.
a. A minimum separation of 5 feet is required between driveway and the property line.
b. Maximum driveway slopes shall not exceed 15%. Driveways exceeding 8% shall provide
slotted drains.
c. The maximum width of single loaded garage driveway shall not exceed nine feet (9') and
double-loaded garage driveway shall not exceed sixteen feet (16').
11. Paving and trench restoration shall comply with the City’s Trench Restoration and Overlay
Requirements.
12. Payment of the transportation impact fee is applicable on the construction of the development
at the time of application for the building permit. The current rate of transportation impact fee
is $175,001.82 for 62 condominiums ($2,822.61 x 62 units). The transportation impact fee that is
current at the time of building permit application will be levied.
13. Traffic concurrency is provided under separate cover.
