Becker Short Plat DCI 15378.21
Section 1 – Project Overview
The proposed Elma Short Plat project consists of a 5-lot short plat at 134 Elma Avenue NE. The
Site contains an existing house and several outbuildings with a gravel driveway. Vegetation is
mostly grass with landscaping and scattered trees. All existing improvements will be removed. A
new private road will be installed for the future houses. Trees will be retained per Renton code.
The site is relatively flat with a slight slope to the east. The northeast portion of the site slopes
down to the east at up to 10%. Runoff is sheet flow to the east toward the adjoining unopened
right-of-way for 140th Avenue SE, which contains a 36-inch CMP storm drain. Surrounding
properties to the north, west and east are fully developed and connected to the stormwater system
that was install as part of the Laurelhurst Division 2 subdivision constructed around 2006.
The site is located within the Urban Growth Area and is on predominantly till soils. The Site is
located in a Flow Control Duration Standard Matching Forested Condition and Basic Water
Quality Area.
The overall Site is approximately 41,531 SF. Postdeveloped Site conditions will consist of 19,931
SF of impervious surface and 21,600 SF of lawn and landscaping.
Site development will include road and utility construction and eventual home construction on the
new lots. A detention tank and Stormfilter are proposed for stormwater flow control and treatment.
New storm drainage will be installed in the proposed private access road. The new storm drain
system will connect to the existing storm drain in 140th Avenue NE. Sewer and water main
extensions will also extend into the site from Elma Avenue NE. Elma Avenue NE is fully
developed with curb, gutter and sidewalk.
Included are Figures 1.1 – Technical Information Report Worksheet, 1.2 – Vicinity Map, 1.3—
Soil Map and 1.4 – Basin Map for reference.

Section 3 – Offsite Analysis
Task 1 - Study Area Definition & Maps
The study area was defined as the site and the runoff flow path extending 1 mile downstream for
the resource review and ¼ mile downstream for the field reconnaissance. Runoff from properties
to the north, west and south drains is collected by the drainage system for the surrounding
subdivision. There is little to no upstream runon.
Task 2 - Resource Review
The City of Renton COR Maps, Washington State Water Quality Atlas and other available
prescribed resources were reviewed. The resource review did not reveal any problems within 1
mile downstream from the site that warranted further investigation or mitigation.
Task 3 - Field Reconnaissance
A field reconnaissance was conducted on September 26, 2018. Conditions were partly cloudy
and dry.
Task 4 - Drainage System Description and Problem Screening
See Figure 3.1 – Offsite Analysis Map
Runoff from the site sheet flows east where it is intercepted by the 36-inch storm drain that runs
through 140th Avenue SE and NE 1st Street. One manhole (Renton ID# 117169) was not readily
located and appears to be covered. Sheet flow runoff is collected in roadside ditches in NE 1st
Street and conveyed through 18-inch CPEP into the 36-inch pipe system in NE 1st Street. Ditches
were well vegetated with no evidence of flooding or erosion problems. Runoff continues east in
NE 1st Street in a pipe system consisting of 36-inch CPEP and Type 2 catch basin. The pipes and
catch basins were clean, with no evidence of problems. At Hoquiam Avenue SE, the pipe system
turns and runs south. Runoff continues south in a 36-inch CPEP pipe system with Type 2 catch
basins. This system extends beyond the ¼ mile downstream point near SE 2nd Place. The pipes
and catch basins were clean, with no evidence of problems.
Task 5 – Mitigation of Existing or Potential Problems
Our investigation revealed no problems that warrant additional mitigation beyond the application
of Flow Control BMPs and the Flow Control Duration Standard Matching Forested Condition
standard.

Part A - Existing Site Hydrology
The entire site was modeled as Forest in the predeveloped condition. The WWHM2012 computer
model was used for basin hydrology. detention tank sizing and water quality flow rate
computations. The complete WWHM report is included in Appendix A. Following are a table
summarizing the various areas and a screenshot of the WWHM input parameters.
Part B – Developed Site Hydrology
Developed site will include the impervious roof, driveway and walkways for the future houses and
private common access road. It is anticipated that some form of BMPs will be applied such that
the maximum effective impervious area will be limited to 3,200 SF for each lot. This may include
restricted footprints as the final option. The remainder of the site will be landscaped and is
modeled as lawn.

Part C – Performance Standards
The Project is in a Flow Control Duration Standard Matching Forested Condition and Basic Water
Quality Area.
Part D – Flow Control System
The Flow Control system for this project included onsite BMPs and a detention tank system.
BMPs
In accordance with City of Renton Surface Water Design Manual Section 1.2.9.3.1, the subdivision
infrastructure improvements shall meet the requirements of Section 1.2.9.3.2 (Small Road
Improvement BMPs). BMP selection and feasibility/infeasibility is discussed below.
Implementation of the on-site BMPs required for the individual lots will be deferred until the
permit stage for the individual lots.
BMPs for Plat Infrastructure
Full Dispersion
Full Dispersion is not feasible due to the lack of available flowpaths. Full Dispersion requires
runoff to be dispersed through 100 feet of native vegetated surface. These conditions are not
feasible with this project.
Full Infiltration
Full Infiltration is not feasible on this project. Full Infiltration requires medium to coarse sands
with 3 feet of separation from the bottom of the facility to a restrictive layer (wet season water
table or hardpan). The soil investigation found dense lodgment till (hardpan) at only 6 to 18 inches
below ground surface across the site, so the vertical separation criteria are not met. Two soil logs
had about 12 inches of dense silty sand with gravel between the topsoil and the hardpan layer.
These soil condition are not feasible for Full Infiltration.
Limited Infiltration
Limited Infiltration requires 3 feet of separation from the bottom of the facility to a restrictive layer
(wet season water table or hardpan). The soil investigation found dense lodgment till (hardpan) at
only 6 to 18 inches below ground surface across the site, so the vertical separation criteria are not
met.
Bioretention
Bioretention for the road surface runoff is not feasible due to inadequate soil depth. A bioretention
planter or swale with a 6 inch freeboard, 6 inch storage depth and 18 inches of bioretention soil
would place the bottom of the facility 30 inches below grade and in an impermeable soil layer,
which on this site is only 6 to 18 inches below grade.
Permeable Pavement
Permeable Pavement is not feasible for the common access drive. A restrictive layer (hardpan) is
present at only 6 inches below existing grade in the location of the common access drive (TP-1
and TP-2). Permeable pavement requires at least 1 foot from the bottom of the base material to a
restrictive layer. Permeable pavement is considered feasible for the maintenance access road to
the detention system. In this area, the restrictive layer is 18 inches below grade and finish grading
21
Becker Short Plat DCI 15378.21
will allow the vertical separation to be met. This maintenance access road is also considered non-
pollution generating as it is not subject to regular vehicular use (per definition).
Basic Dispersion
Basic Dispersion for the common access road due to lack of available flow path. The 20-foot wide
road would require a 2-foot dispersal strip followed by 10 feet of vegetated flow path for sheet
flow dispersal. This area is not available next to the road. Other dispersion BMPs require even
longer flow paths.
Soil Amendment
Soil amendment is feasible and shall be used in the landscape buffer and other areas disturbed by
short plat development, such as over the detention system.
22
Becker Short Plat DCI 15378.21
Flow Control Facility
A detention tank is proposed to provide flow control meeting the Flow Control Duration Standard
Matching Forested Condition standard. Multiple iterations were run to determine an appropriate
tank size and control structure configuration. The facility configuration is summarized in the
following screen shot. The complete WWHM report is included in Appendix A. The report shows
the proposed configuration “passes” the duration standard test.
23
Becker Short Plat DCI 15378.21
Part B – Water Quality Systems
The project involves more than 5,000 SF of PGIS. A Stormfilter is proposed to provide the
required Basic Water Quality treatment. Presettling is provided by the detention tanks. The
required treatment flow rate was extracted from the WWHM analysis and is shown in the following
screenshot. The treatment flow rate of 0.013 CFS (5.85 GPM) will require 1 ZPG Stormfilter
cartridge (7.5 GPM/cartridge). The water quality treatment flow rate results are shown below.

The new conveyance pipe in Tract A will be a 12-inch CPEP with a minimum slope of 0.5%. The
100-year (pre-mitigation) flow rate was computed using WWHM to be 0.5 CFS.
The proposed pipe has a full flow capacity of 2.5 CFS at 3.2 feet/second as shown below. If
necessary, a backwater analysis will be performed at the final engineering stage.

Subject: Stormwater Infiltration Feasibility Study
134 Elma Avenue Northeast

RGI Project No. 2018-139
Dear Mr. Woodbridge:
As requested, The Riley Group, Inc. (RGI) is pleased to provide the results of our recent subsurface
characterization services at 134 Elma Avenue Northeast in Renton, Washington (Figure 1).
Subsurface Conditions
RGI observed the completion of four test pits (TP-1, TP-2, TP-3, TP-4) to assess shallow subsurface
soil and groundwater conditions for potential infiltration of stormwater at the Site. The test pits
were completed using a subcontracted mini-excavator. The location of the four test pits are
shown on Figure 2.
Review of the Geologic map of the Renton quadrangle, King County, Washington, by Mullineaux,
D.R. (1965) indicates that the soil in the project vicinity is mapped as Vashon-age lodgment till
(Qvt), which is a nonsorted mixture of very dense silty sand with gravel and cobbles.
Review of the Preliminary Geologic Map of Seattle and Vicinity, Washington, by Waldron, H.H, et
al (1962) indicates that the soil in the project vicinity is mapped as Vashon-age lodgment till (Qvt),
which is a nonsorted mixture of very dense silty sand with gravel and cobbles.
In general the site soils encountered were comprised of a surface layer of sod and topsoil
underlain by very dense, silty sand with gravel interpreted to be glacially consolidated lodgment
till soils. No groundwater was encountered in any of the test probe borings.
Infiltration Feasibility
As described above glacially consolidated soils were encountered in all of the test probes
completed at the site. In test pits TP-1, TP-2, and TP-3 the unweathered very dense lodgment till
was encountered at a depth of six inches. In test pit TP-4 the unweathered very dense lodgment
till was encountered at approximately 18 inches.
Based on the presence of hydraulically restrictive soils comprised of glacially consolidated
lodgment till at very shallow depths below the topsoil at the site and separation distances
prescribed in City of Renton stormwater manual infiltration is considered infeasible at the Site.

GENERAL NOTES
1: Soil classifications are based on the Unified Soil Classification System. Descriptions and stratum lines are interpretive, and actual lithologic changes may be
gradual. Field descriptions may have been modified to reflect results of lab tests.
2: Descriptions on these logs apply only at the specific boring locations and at the time the borings were advanced. They are not warranted to be representative
of subsurface conditions at other locations or times.
