Project Description
The proposed project is development of a mixed-use building at 2900 NE 10th Street in Renton,
Washington. The proposed building will be four stories and will contain 76 affordable housing units with
approximately 13,645 square feet of ground floor space occupied by Renton Housing Authority services
staff. The existing 13,416-square-foot Renton Housing Authority building on the site will be removed.

ESA-listed species occurring in the action area:
The action area for the project includes the terrestrial and aquatic habitats that could be directly or indirectly affected by the proposed project:
• For potential terrestrial impacts, the action area is defined as the distance project related construction
noise will travel before it is indistinguishable from background ambient noise, which is calculated as
approximately 0.75 miles from the project area. Construction noise, which would be short-term and
limited to daytime and weekday hours, is estimated to be as loud as 93 A-weighted decibels (dBA),
measured 50 feet from the construction equipment that will be used to construct the project. The
communities adjacent to the project area are estimated to have an environmental noise baseline of 55
dBA (WSDOT. 2020. Biological Assessment Preparation for Transportation Projects - Advanced
Training Manual. Version 2020. Washington State Department of Transportation. August).
• For potential aquatic impacts, the aquatic component of the action area would account for any in-water
work or stormwater runoff from the project to surface water bodies (i.e., streams and/or wetlands). No
wetlands or streams occur on the project site, and no in-water work will occur. However, stormwater
runoff from the completed project will be conveyed in the existing City drainage network which
discharges to Johns Creek approximately 1 mile downstream of the project site. Johns Creek discharges
to Lake Washington at Gene Coulon Beach Park, which is located approximately 1.8 miles downstream
from the project site. For potential aquatic impacts, the aquatic component of the action area extends
approximately 400 ft from the confluence of Johns Creek at Lake Washington pursuant to allowed
mixing zone distances in lakes provided in Washington Administrative Code 173-201A-400.
Chinook and steelhead are documented in Lake Washington but not in Johns Creek.

Have you treated all stormwater to the design storm within the contributing
impervious area?
If no, why not, and how will you offset the effects from remaining stormwater?
Stormwater management complies with the 2017 City of Renton Surface Water Design Manual
(CORSWDM). To comply with the City of Renton’s (COR) National Pollutant Discharge
Elimination System (NPDES) permit, the COR adopted the 2016 King County Surface Water
Design Manual with Amendments to create the CORSWDM. The Department of Ecology
(DOE) has approved the 2016 King County manual as an equivalent manual to the 2012
Stormwater Management Manual for Western Washington, as amended in 2014. The surface
water standards per the CORSWDM generally increase the use of low impact development
(LID) principles and practices and add requirements to manage stormwater on-site to minimize
impacts to water quality and aquatic habitat in the COR.
Water quality treatment facilities and on-site Best Management Practices (BMPs) are provided
for 99.7% of impervious surfaces on-site. See Attachment A for On-Site BMPs Exhibit
illustrating how each impervious surface is mitigated.
Stormwater runoff from target pollution-generating surfaces will be treated with infiltrating
bioretention planters per Section 1.2.8.1 of the CORSWDM. Impervious surfaces mitigated
with infiltrating bioretention planters include the parking lot and driveway.
Non-pollution generating impervious surfaces on-site not tributary to the infiltrating
bioretention planters and not required to undergo water quality treatment will be mitigated with
on-site BMPs per Section 1.2.9.2 of the CORSWDM, to the maximum extent feasible. Based on
the COR’s basin analysis, flow control requirements are waived for the project. On-site BMPs
provide partial flow mitigation by maximizing infiltration and retention of stormwater on-site.
Refer to the Technical Information Report, Section 2, Core Requirement No. 3 Flow Control for
flow control facility requirements discussion.
Runoff from the proposed building roof will be routed to gravel filled infiltration trenches for
limited infiltration prior to discharging to the public storm main. Pedestrian pathways include
permeable pavers. Soil amendments will be applied to new landscaping areas to improve soil
quality and stormwater infiltration and retention properties.
The remaining 0.3% of impervious surfaces on-site not mitigated with the above BMPs are
considered infeasible due to existing site grading constraints. This area at the edge of driveway
connecting to the public right-of-way is unable to gravity flow to one of the proposed BMPs.
Permeable pavers are not feasible because the native soils do not meet required soil suitability
criteria for providing treatment per Section C.2.7.1 of the CORSWDM nor contain required
properties that reduce risk of groundwater contamination per Section 5.2.1 of the CORSWDM.
Considering no existing or potential problems were discovered during the off-site review, this
105 SF of bypass area is not anticipated to significantly impact downstream systems or habitats.
Refer to the Technical Information Report, Section 3 for off-site analysis.

Treatment train, including pretreatment and bioretention methods used to treat water quality
Pollution-generating hard surfaces within the parking lot and driveway will be treated with infiltrating
bioretention planters.
Building roof runoff will be routed to gravel filled infiltration trenches for limited infiltration prior to
discharging to the public storm main.
Non-pollution generating pedestrian pathways will include permeable pavers.
Soil amendments will be applied to new landscaping areas to improve soil quality and stormwater infiltration
and retention properties.
Why this treatment train was chosen for the project site
Water quality facilities and on-site BMPs were implemented to the maximum extent feasible and designed to
satisfy requirements of the City of Renton Surface Water Design Manual (CORSWDM).

Methods used to treat water quantity
None proposed. Per Section 1.2.3.1.A of the CORSWDM, the facility requirement in Peak Rate Flow
Control Standard areas is waived for any threshold discharge area in which the target surfaces subject to
Core Requirement No. 3 Flow Control will generate no more than a 0.15 CFS increase in the existing site
condition’s 100-year peak flow. Existing site conditions are defined as conditions that existed prior to
May 1979, unless land cover changes have been approved by the COR since May 1979 as part of a permit
or approval. Current site conditions were constructed as part of an approved permit in 1982, so the
“existing site condition” to be used for flow control analysis purposes shall be the current land use. The
project includes on-site BMPs and will not generate more than a 0.15 CFS increase in the existing site
condition’s 100-year peak flow; therefore, Core Requirement No. 3 Flow Control is not applicable.
