SUBJECT: Utility and Transportation Comments for Sandhu Short Plat
13952 SE 159th Place
LUA 21-000143
I have reviewed the application for the Error! Reference source not found. at 13952 SE 159th Place (APN
2223059022) and have the following comments:
EXISTING CONDITIONS
The site is approximately 0.65 acres in size and is rectangular in shape. “An existing, two-story single-family
residence with a basement that daylights to the north is present at the eastern portion of the site. The existing
residence has an attached three-car garage located at the southeast side of the existing residence. An accessory
building or detached garage is located at the middle of the west side of the site. A paved loop driveway is
present at the central portion of the site to provide vehicular access to the attached 3-car garage and the
detached garage with access at two locations along SE 159th Place. The driveway is paved with asphalt concrete
closest to the SE 159th Place and Portland concrete cement between the two garages. Concrete stairs are
located west of the existing residence.” (Otto Rosenau & Associates, Inc., Geotechnical Report, June 25, 2019)
Water Water service is provided by Cedar River Water and Sewer District.
Sewer Wastewater service is provided by the Cedar River Water and Sewer District.
Storm There is an existing storm drainage system in SE 159th Place. The existing property does not contain
stormwater facilities. Runoff from the existing site includes roof downspouts from the single-family
residences where no stormwater infrastructure currently exists on-site. Runoff from the site sheet
flows north into top the adjacent properties.
Streets SE 159th Place is a Residential Street with an existing right of way (ROW) width of 48 feet as measured
using the King County Assessor’s Map. The existing roadway is a paved width of 28-foot with a rolled
curb and a 5-foot sidewalk on either side of the roadway.

CODE REQUIREMENTS
WATER
1. A water availability certificate from Cedar River Water and Sewer District has been provided and the
project is able to be serviced by the District.
SEWER
1. A sewer availability certificate from Cedar River Water and Sewer District has been provided and the
project is able to be serviced by the District.
SURFACE WATER
1. A geotechnical report, dated June 25, 2019, completed by Otto Rosenau & Associates, Inc. for the site
has been provided. The submitted report describes the site is a Low Erosion Hazard area of the till soils
on site. 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 a measured infiltration
rate of 1.25 inches per hour on the south side of the western lot and it provided recommendations for
project design and construction. Geotechnical recommendations presented need to be address within
the project plans.
2. A Storm Drainage Report was not submitted 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 Lower Cedar River Drainage Basin. The development is anticipated to trigger
Simplified Drainage Review based on the addition of one new single-family lot in accordance with the
2016 City of Renton Surface Water Design Manual (RSWDM). All core requirements and the six special
requirements must be discussed in the storm drainage report/assessment. It does appear that Onsite
BMPs will be able to be addressed on site to mitigate for the impervious area added on the new lot.
Note: If new/replaced effective impervious area exceeds 5,000 square feet, directed drainage review
may be required.
3. A Construction Stormwater General Permit from Department of Ecology will be required if grading and
clearing of the site exceeds one acre. A Stormwater Pollution Prevention Plan (SWPPP) is required for
this site. Currently the site does not appear to trigger this requirement.
4. A surface water development fee of $2,000.00 per new single-family residence will apply. This is subject
to final design and payable prior to issuance of the storm water utility permit.
TRANSPORTATION
1. The proposed development fronts SE 159th Place along the south property lines. SE 159th Place is a
Residential Street with an existing right of way (ROW) width of 48 feet as measured using the King County
Assessor’s Map. The existing roadway is a paved width of 28-foot with a rolled curb and a 5-foot sidewalk
on either side of the roadway. To meet the City’s complete street standards for residential street,
minimum right of way width is 53 feet. Dedication of 2.5 feet of right of way would be required.
The applicant has requested a street modification to modify the ROW width and street cross section
match the existing improvements. City Staff has reviewed the requested modification and will support
the modification to match the established standard street section for SE 159th Place since it is within an
established neighborhood, provides safe access for pedestrians and vehicles.

2. Current City standards require a turnaround for dead-end streets greater than 150 feet. Dead-end
streets up to 300 feet may utilize a hammerhead turnaround provided it meets the requirements for
emergency services access, including a 25-ft inside and 45-ft outside turning radius. Dead end streets are
limited to 700-feet maximum. Reference RMC 4-6-060H. This project does not have the required fire
apparatus access; however, the Renton Regional Fire Authority will support the installation of a fire
sprinkler system in lieu of providing the required fire apparatus access.
3. The proposed subdivision is anticipated to create one additional PM Peak Hour Vehicle Trip for the new
additional single-family lot. It is not anticipated to adversely impact the City’s transportation system.

with City standard plans 104.1 and 104.2.
5. Paving and trench restoration shall comply with the City’s Trench Restoration and Overlay Requirements.
6. The current rate of transportation impact fee is $10,861.69 per dwelling unit for single family homes.

Traffic impact fees will be owed at the time of building permit issuance.
GENERAL COMMENTS
1. Adequate separation between utilities as well as other features shall be provided in accordance with
code requirements (if applicable).
a. 7-ft minimum horizontal and 1-ft vertical separation between storm and other utilities is required
except for water lines which require 10-ft horizontal and 1.5-ft vertical.
b. The stormwater line should be minimum 5 feet away from any other structure or wall or building.
c. Trench of any utility should not be in the zone of influence of the retaining wall or of the building.

be underground. The construction of these franchise utilities must be inspected and approved by a City
of Renton inspector.
