PROJECT OVERVIEW
This project involves subdividing a 1.4acre parcel into 10 single-family residential
lots. The site is located along the north side of NE Sunset Blvd., in the SE '/4 of
Section 4 of Township 23 North, Range 5 East. The existing conditions consist
of a single-family residence. The general ground cover in the south portion of the
site is lawn, and north portion of the site is generally covered with blackberry
bushes. The underlying soils are Alderwood/Arents. In the north portion of the
site, a small ravine begins near the east property line and drains west across the
site. On-site flows drain southwest and northwest into the ravine. Approximately
70' south of the northwest property corner, the onsite flows leave the site where
the Level 1 Drainage Analysis begins.
UPSTREAM TRIBUTARY AREA
Approximately, 0.50 acres of upstream area drains onto the site. The upstream
tributary area is comprised of lawns in single family-residential lots located north
and west of the site. There are no apparent drainage problems associated with
these upstream flows.
LEVEL 1 DRAINAGE ANALYSIS
From the west property line of the site, the runoff flows west in shallow channels
along the bottom of a heavily vegetated ravine at an approximate slope of 1%-
4%. As the runoff continues west, the ravine loses its definition and drains into a
retirement center's yard drain approximately 200' from the site's west property
line. Due to the heavy vegetation and mild grades, the runoff draining into the
yard drain is minimized. From the yard drain, the runoff continues west in a 6"
pipe (P1) approximately 1 00' where it drains into a catch basin located in the
retirement center's access road. Then, the runoff is conveyed south
approximately 30' (P2) and drains into a water quality system (P3). The runoff
exists the water quality system approximately 100' south through a 12" diameter
pipe (P4). Approximately 150' west of the water quality system, the pipe drains
into a catch basin. From the catch basin, the runoff continues southwest
approximately 100' (P5) along the centerline of the retirement center's south
access road where it drains into another catch basin. The runoff continues
southwest in the pipe approximately 75' from the previous catch basin and drains
into another catch basin located in the sidewalk west of the access road. Then,
the pipe (P7) conveys the runoff south approximately 80' and drains into a catch
basin located in the center of NE 15th PI., where the City of Renton storm system
begins. The runoff continues west approximately 200' (P8) where it drains into a
catch basin located at the intersection of NE 15th PL and Kirkland Ave NE. Then,
the runoff continues south approximately 250' (P9) to the intersection of NE 14th
St. From the catch basin, the run continues south (P10) along Kirkland Ave NE
in the City of Renton storm system further than a '/4 of a mile downstream from
the site. There are no apparent capacity or water quality problems along this
drainage path.
The site's proposed storm system consists of the onsite flows collecting in a
water quality vault and being discharged to a level spreader near the west
property line.
