Code Related Comments:
1. The fire flow requirement for a single family home is 1,000 gpm minimum for dwellings up to 3,600
square feet (including garage and basements). If the dwelling exceeds 3,600 square feet, a minimum of
1,500 gpm fire flow would be required. A minimum of one new fire hydrant is required within 300-feet
of the proposed buildings and two hydrants if the fire flow goes up to 1,500 gpm. A certificate from King
County Water District 90 will be required to assure the demand can be met.
2. Fire department apparatus access roadways are required within 150-feet of all points on the building.
Fire access roads are required to be a minimum of 20-feet unobstructed width with turning radius of 25-
feet inside and 45-feet outside minimum. Fire lane signage required for the onsite roadways. Roadways
shall support a minimum of a 30-ton vehicle and 75-psi point loading. Maximum slope is 15% grade.
Dead end streets that exceed 150-feet require an approved fire apparatus turnaround. It can be either
a hammerhead or a cul-de-sac. Cul-de-sac are not allowed to contain landscape islands. Dead end roads
over 300 feet require a cul-de-sac. Cul-de-sacs must have a 90 foot diameter. Any dwelling more than
500 feet down a dead end road must have fire sprinklers. In this case this seems to pertain to lots #6, 7,
8, 9 and 10. Lots that are over 700 feet down a dead end road are not allowed at all.
The Renton Regional Fire Authority supports the City of Renton policy to provide a gridded public street
system. To that end, the proposed Cul-de-sac shall be eliminated and replaced with a potential through
street by the development of the 164th Ave Southeast right of way.

1. After reviewing the submitted documents for this project, additional clarification is requested on the
future plan to complete the Boundary Line Adjustment Agreement that is listed on the title report for
the property as Recording No. 20030310002076. Based on the boundary survey and the Agreement to
Cooperate in Boundary Line Adjustment, it does not appear that the BLA has been complete nor
recorded to date. The area that was agreed upon in the agreement is a part of the proposed Tract B
Tree Retention area and would affect the square footage amounts of the proposed plat. The BLA
should be complete prior to final plat recording to ensure all boundary lines are in the final layout.

I have completed a preliminary review of the application of the above-referenced proposal located at
parcel 1457500025 and have the following comments: The applicant is proposing to subdivide the lots
into 13 single family lots with tracts for drainage and open space. All existing structures on the parcels
will be removed.
EXISTING CONDITIONS
The Site is approximately 4.18 acres in size and is rectangular in shape. The existing site is developed
with an existing single family residence and a large amount of vegetation located throughout the parcel.
Water Water service is provided by King County Water District 90.
Sewer Sewer service is provided by the City of Renton. There is an existing 8” PVC sewer
running from north to south in 162nd Ave SE west of the site. Reference Project File S-
368803 in COR Maps for record drawings. Wastewater in this main flows into the east
side interceptor to the west of the property.
Storm Currently there are no storm drainage improvements along any of the frontages of the
project. Drainage from the site either infiltrates or sheet flows south. There have been
multiple reports of drainage problems to the south east of the project site.
Streets The proposed development fronts two undeveloped right of ways, 162nd Ave SE and
164th Ave SE. 162nd Ave SE is located on the west property line and 164th Ave SE is
located on the east property line. Both roadways are classified as Residential access
streets. The existing right-of-way (ROW) width is for 162nd Ave SE approximately 60
feet. The existing right-of-way (ROW) width of 164th Ave SE is approximately 30 feet.

The route will begin on the west side of the property and will continue within Road A to the east
until it intersects with 164th Ave SE. From 164th Ave SE the sewer will flow to the south till it
reaches the intersection of 164th Ave SE and SE 135th St. Once sewer reaches SE 135th St the
will need to run the sewer line from the west to the east along SE 135th St, meeting at the
intersection at 166th Ave SE. Sewer main the need to extend from the intersection to the SSMH
located (SSMH 5625).
a. The extension of this main is located within King County Right of Way. The applicant
will need to get permission from King County to work with their right of way.
b. The sewer main shall be a minimum diameter of 10 inch. Sewer mains and manholes
shall be designed and installed in accordance with City and Department of Ecology
standards.
c. Applicant will need to reference the recorded easement for the sewer extension
connecting to SSMH5625.
d. Sewer extension is proposed within a parcel 132305UNKN. The applicant will need to
obtain permission from the owner in order to use this parcel for the sewer main. A 10
foot easement to the City of Renton will need to be grated overtop of the sewer main.
STORM DRAINAGE COMMENTS
1. The development is subject to stormwater system development charges (SDCs). The 2019
stormwater SDC is $1,800.00 per lot. The SDC will be collected for each new lot. SDCs are due at
the time of civil construction permit issuance.
2. Drainage plans and a drainage report complying with the adopted 2017 Renton Surface Water
Design Manual will be required.
3. A preliminary Drainage Plan and Technical Information Report (TIR), dated November 26th,
2018, was submitted by DR Strong Consulting Engineers with the Land Use Application. Based on
the City of Renton’s flow control map, the site falls under Flow Control Duration Standards
(Forested Conditions) and is located within the Lower Cedar River drainage basin. The
development is subject to a Full Drainage Review in accordance with the 2017 Renton Surface
Water Design Manual (RSWDM). All nine core requirements and the six special requirements
have been discussed in the Technical Information Report. The detention, water quality and
conveyance shall be designed in accordance with the RSWDM that is current at the time of the
civil construction permit application.
a. The development is also proposing to install a stormwater detention vault located on
the Southeast corner of the proposed development with a discharge to the north Cedar
River Drainage Basin. The Storm water vault has been sized assuming that no credits will
be taken for BMP’s however the applicant has proposed to use dispersion and reduced
impervious surface BMP credits for the individual build lots.
i. Applicant has assumed that maximum of 4,000 sf feet of impervious surface
for each lot as described in RSWDM.
b. The development is also proposing to install a pipe system within the 162nd Ave SE
located on the west end of the property. System will need to be sized in accordance
with the 2017 RSWDM.

c. Applicant is proposing to discharge the water from the project via an existing 12 inch
storm pipe located at the intersection of SE 136th St and 164th Ave SE.
i. Pipe sizing for the outfall will need to be sized in accordance with the Renton
Surface water design manual. This pipe is located within King County, a
separate permit from King County is required.
d. On-site BMPs satisfying Core Requirement #9 will be required for the site. On-site
BMPs shall be evaluated in order of preference by feasibility as described in Section
C.1.3 of the 2017 RSWDM. Applicant proposes to use bio retention facilities wherever
possible in the planter strips along the onsite roadway. Perforated pipes will be
installed for each of the individual lots and will be tight lined to the proposed
stormwater conveyance system.
i. Per the Geotechnical report submitted by Earth Solutions NW, infiltration is
not suitable for this site due to the existing soils onsite.
ii. Basic dispersion is currently proposed. If feasible, basic dispersion should be
implemented to the maximum extent feasible which may be more than 10% of
the total lot area. Feasibility of on-site BMPs for each lot will be reviewed at
the time of single family building permit review. Final TIR should clearly
explain how target surfaces from plat infrastructure (road and sidewalk) are
mitigated by on-site BMPs or how BMPs are infeasible for these surfaces.
iii. Final BMP credits will be confirmed at building permit review.
4. A Geotechnical Report, dated September 28th, 2018, completed by Earth Solutions NW, LLC for
the site has been provided. The submitted report describes the existing soils to contain silty
sands that are medium dense to dense. The Geotechnical report mentions that infiltration is not
feasible due the types of soils that are located onsite, the geotechnical recommends that
stormwater control use a different method.
5. Storm drainage improvements along all public street frontages (new internal site streets, 162nd
Ave SE and 164th Ave SE) are required to conform to the City’s street standards. New storm
drain shall be designed and sized in accordance with the standards found in Chapter 4 of the
2017 Renton Surface Water Design Manual.
i. Pipe should be located within the curb line of the future roadway.
ii. Overall conveyance sizing will be determined based on Conveyance Analysis
in accordance with Core Requirement #5 of the RSWDM. The size of the
conveyance system may be larger than 12-inches.
iii. The conveyance system shall be sized and located in order to convey and
contain a minimum of 25-year peak flow assuming developed conditions for
onsite tributary areas and existing conditions of any offsite tributary area.
iv. Applicant will need to place a catch basin at each property line limit
between the City of Renton and King County Jurisdictions.
6. A Construction Stormwater General Permit from the Washington Department of Ecology is
required as site clearing will exceed one acre.

SEPA Environmental checklist (WAC 197-11-960) July 2016 Page 1 of 12
SEPA ENVIRONMENTAL CHECKLIST
Purpose of checklist:
Governmental agencies use this checklist to help determine whether the environmental impacts of your
proposal are significant. This information is also helpful to determine if available avoidance, minimization
or compensatory mitigation measures will address the probable significant impacts or if an environmental
impact statement will be prepared to further analyze the proposal.
Instructions for applicants:
This environmental checklist asks you to describe some basic information about your proposal. Please
answer each question accurately and carefully, to the best of your knowledge. You may need to consult
with an agency specialist or private consultant for some questions. You may use “not applicable” or
"does not apply" only when you can explain why it does not apply and not when the answer is unknown.
You may also attach or incorporate by reference additional studies reports. Complete and accurate
answers to these questions often avoid delays with the SEPA process as well as later in the decision-
making process.
The checklist questions apply to all parts of your proposal, even if you plan to do them over a period of
time or on different parcels of land. Attach any additional information that will help describe your proposal
or its environmental effects. The agency to which you submit this checklist may ask you to explain your
answers or provide additional information reasonably related to determining if there may be significant
adverse impact.
Instructions for Lead Agencies:
Please adjust the format of this template as needed. Additional information may be necessary to
evaluate the existing environment, all interrelated aspects of the proposal and an analysis of adverse
impacts. The checklist is considered the first but not necessarily the only source of information needed to
make an adequate threshold determination. Once a threshold determination is made, the lead agency is
responsible for the completeness and accuracy of the checklist and other supporting documents.
Use of checklist for nonproject proposals:
For nonproject proposals (such as ordinances, regulations, plans and programs), complete the applicable
parts of sections A and B plus the SUPPLEMENTAL SHEET FOR NONPROJECT ACTIONS (part D). Please
completely answer all questions that apply and note that the words "project," "applicant," and "property or
site" should be read as "proposal," "proponent," and "affected geographic area," respectively. The lead
agency may exclude (for non-projects) questions in Part B - Environmental Elements –that do not
contribute meaningfully to the analysis of the proposal.
