RE: Preliminary Subdivision Submittal
Twin Trails Subdivision
Dear Mr. Niven:
Please accept this letter and accompanying information on behalf of Prospect
Development, as our subdivision application with City of Federal Way. We would like to
submit for review the development of King County Tax Parcel number 242103-9051 and
a portion 242103-9008. The property is located at 1605 SW 341st Pl.
Project Description
The project site totals approximately 9.28 acres of RS-7.2 zoned land. The applicant is
seeking to subdivide the land into 38 single-family residential lots, including a 60’ wide
public road, a 52’ wide public cul-de-sac, half road of a 78’ wide public road, four (4) private
access tract, one (1) tree retention tract, and one (1) stormwater tract.
Tree Retention
The applicant is proposing a tree replacement tract (Tract F) between the start of the cul-
de-sac bulb and proposed lots #3 and 4). The project does not propose to retain any
existing trees but will replace the 167 tree credit units required by code.
Recreation Space
The project does not propose any on-site recreation area and is requesting to pay a fee-
in-lieu of providing recreation space. Please see the attached fee-in-lieu of recreation
space request letter.
Stormwater
The applicant has proposed a stormwater facility within Tract A. The tract is located in the
northern portion of the site, adjacent to 19th Ave SW. The tract area is approximately
22,070 SF.

Utilities
The project’s water and sewer service will be provided by Lakehaven Water & Sewer
District. The applicant has received Water and Sewer Availability Certificates and are
being submitted with this application.
Water services will be extended south from the existing main on 19th Ave SW to SW 344th
St. Sewer services will be extended south from the existing sewer main on SW 341 st Pl to
SW 344th St.
Access
The proposed vehicular access to the development will be provided through a new 60’
wide public road connecting the existing 19th Ave SW to the future SW 344th St. The project
will also require a new 52’ wide public cul-de-sac on the southwestern portion of the
development. The applicant is proposing half road improvements and dedication for SW
344th St. The 39’ wide improvements will include, curb and gutter, sidewalk, and a bike
lane. Additionally, the applicant is proposing three (3) 28’ wide shared access tract,
providing access to up to four (4) lots each. A 20’ wide private access tract is proposed
for access to lots #7 and 8.
As currently proposed the vehicular block perimeter exceeds the 2,640 LF threshold. The
City has requested an additional connection to the future SW 344 th St, which the applicant
does not believe would be advantageous to the City. Please see the attached block
perimeter waiver request.
