DATE OF NOTICE OF APPLICATION: November 15, 2019
PROJECT NAME/NUMBER: PR19-000453 Heather Downs Detention Pond WQ
Retrofit / LUA19-000293
PROJECT LOCATION: NE corner of SE 4th St and Union Ave SE (APN

REVIEWED:
Applicant documents are available online through the City of Renton
Document Center website. See also http://bit.ly/32Oq5GH
PROJECT DESCRIPTION: The applicant, the City of Renton, is requesting Environmental (SEPA) Review
in order to convert an existing "back-up" type detention pond to a "flow-through" combination wetpond/detention pond
in order to improve the quality of water discharging into the Maplewood Creek. The site of the existing facility is within
a parcel (APN 3211100010) at the north-east corner of the intersection of Union Ave SE and SE 4th St. The parcel is
located in the R-6 zone and is approximately 8,400 sq. ft. in size. The site abuts single-family homes to the north and
east. The facility, which was constructed in 1983, provides flow control for approximately 29.8 acres of surrounding
residential properties. The existing pond provides little to no water quality treatment and primary functions as a back-
up pond rather than a flow-through-type pond. Water in the pond currently drains into a pipesystem that outfalls to
Maplewood Creek and eventually the Cedar River. Objectives of the proposed project include improving water quality
treatment performance and ensuring the pond meets the Washington Department of Ecology's standards for
stormwater facilities. Additional work may include limited vegetation and tree removal and replacement of an existing
fence around the facility. The applicant submitted a design report prepared by Loius Berger that includes hydrology and
geological analyses. Two preferred alternatives analyzed in depth in the report. Alternative 1 would create a two-cell
pond with an access road that divides the cells and provide 0.14 ac-ft of new wetpond storage, while Alternative 2 would
create a one-cell pond with a standard access road and would provide 0.17 ac-ft of new wetpond storage. Based on
factors including cost, wetpond storage capacity, and ease of construction, the report concludes that Alterative 2 is
preferable. The total construction cost was estimated at $409,000, part of which would be funded via a Department of
Ecology grant. The applicant intends to complete the project in the summer of 2021. No critical areas are present on the
project site according to COR maps.
