SUBJECT:LUA-Application Comments for 38th Street Short Plat
LUA18-000683
I have reviewed the Land Use Application submittal for the 38th Street Short Plat at 1825 NE 38th
Street (KC Parcel ID: 3345700220). The applicant is proposing to subdivide the existing lot into 8
lots for single family homes. The existing home is proposed to be removed.
EXISTING CONDITIONS
The Site is approximately 1.46 acres in size and is trapezoidal in shape. The existing site is
developed with an existing single family residence and a large amount of trees located
throughout the parcel.
Water Water service is provided by the City of Renton. The site is in the Kennydale water
service area in the 320’ hydraulic pressure zone. The approximate static water pressure
is 71 psi at an elevation of 155’. Static water pressure varies based on topography.
There is an existing 12” water main east of the site in Lincoln Avenue NE that can
provide 2,500 gallons per minute (gpm). Reference COR Project File WTR2700400 in
COR Maps for record drawings.
Sewer Sewer service is provided by the City of Renton. There is an existing 8” sewer east of the
site along the western frontage of Lincoln Avenue NE that flows from south to north.
Reference COR Project File WTR2703908 and WWP2702843 in COR Maps for record
drawings.
Storm The site contains an existing single family home surrounded by wooded area. There is no
mapped on-site conveyance system. The current site topography appears to drain the
runoff from the site to the northwest. The site and offsite areas to the northwest
contain moderate and high landslide hazards, high erosion hazard areas, and regulated
slopes up to a 90% grade. There is a 12” public storm drain east of the site along the
eastern frontage of Lincoln Avenue NE that flows from south to north. There is also an
existing stormwater conveyance swale north of the site in NE 38th Street that flows from
east to west.
Streets The proposed development fronts Lincoln Ave NE along the east property line. Lincoln
Ave NE is classified as a Residential Access street. Existing right-of-way (ROW) width is
approximately 60 feet. The proposed development fronts NE 38th Street along the north
property line. NE 38th Street is classified as a Residential Access street. Existing right-of-
way (ROW) width is approximately 60 feet.

exceeds 80 psi.
6. If irrigation is proposed for the common areas, a landscape irrigation meter and double
check valve assembly is required (DCVA).
7. Civil Construction plans for the water main improvements will be required and must be
prepared by a professional engineer registered in the State of Washington. 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. Adequate horizontal and
vertical separations 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. Retaining walls, rockeries or similar structures
cannot be installed over the water main unless the water main is installed inside a steel
casing.
8. The development is subject to applicable water system development charges (SDC’s)
and meter installation fees based on the number and size of the meters for domestic
uses and for fire sprinkler use. The development is also subject to fees for water
connections, cut and caps, and purity tests. Current fees can be found on the City’s
website. Current fees will be charged at the time of construction permit issuance.
a. The SDC fee for water is based on the size of the new domestic water to serve the
project. The current water fee for a single 1-inch meter is $4,050.00 per meter.
b. The SDC fee for fire service is based on the size of the fire service line to serve the
project.

issuance.
SEWER
1. The existing on-site septic system serving the existing home shall be decommissioned in
accordance with King County Department of Health and City of Renton standards.
2. New 6” side sewers with a minimum slope of 2% connecting to the existing sewer main

where a gravity connection is possible. Private utility easements will be needed for any
side sewer that passes through an adjacent lot prior to connecting to the existing sewer
main.
3. For lots where a gravity connection to the existing sewer main in Lincoln Avenue NE is
not possible, individual grinder pumps and force mains will be required for each lot. The
private force main should connect to a 6” sewer stub that is a minimum of 2% in slope.
Private utility easements will be needed for any force main or gravity side sewer that
passes through an adjacent lot prior to connecting to the existing sewer main.
4. The development is subject to a wastewater system development charge (SDC) fee. SDC
fee for sewer is based on the size of the new domestic water to serve the project. The
current sewer fee for a 1-inch meter install is $3,100.00 per meter. Each lot shall have a
separate meter.
SURFACE WATER
1. Drainage plans and a drainage report complying with the adopted 2017 Renton Surface
Water Design Manual (RSWDM) will be required. Refer to Figure 1.1.2.A – Flow Chart in
the 2017 RSWDM to determine what type of drainage review is required for this site.
The site falls within the City’s Flow Control Duration Standard (Forested Conditions).
The site falls within the May Creek drainage basin.
2.There are regulated slope, erosion hazard, and landslide areas found along the western
side of the property. Due to the steep slopes downstream of the project, the project
must comply with the Flood Problem Flow Control standard. Therefore, if stormwater
will be discharged to the steep slope area then the project must match the Flow
Duration of pre-developed rates for Forested Conditions from 50% of the 2-year up to
the full 50-year flow, match Forested Site Conditions for the 2- and 10-Year Peaks, and
match Existing Site Conditions for the 100-Year Peaks.
3. On-site BMPs satisfying Core Requirement #9 will be required for the site and each
individual lots to the extent feasible. On-site BMPs shall be evaluated in order of
preference by feasibility as described in Section C.1.3 of the 2017 RSWDM. Final review
and approval of the lot BMPs will be evaluated during the review of the Building Permit
Application.
