Preliminary Plat - PROJECT NARRATIVE
Cyprus Lane Plat
15-Lot Development
5 816 NE 4 th PL and 510 Nile Ave NE Renton, WA 98059
The proposal is to subdivide 3 adjoining parcels, Parcel Nos 112305-9021, -9023
fronting NE 4th PL and -9031 fronting Nile Ave NE into 15 SFR lots plus 2 storm
Tracts. The project is located within the East Plateau Planning Area.
Permits required: Land Use Action, ROW, DOE Construction Stormwater
General Permit, Utility, and Building permits.
Zoning designation: The properties and adjoining areas are zoned Single-
Family Residential R-4.
Current Use: Two of the lots have a SFR, one with an attached garage, 9031
and the other with a detached garage, 9021. The third parcel, 9023 is vacant.
Special features: There are no special features on the properties.
Soil Type/Drainage: This property is in an area generally underlain by
Alderwood gravelly sandy loam overlying glacial till soils. The natural drainage is
via sheet flow from the NE corner to the SW corner with an average slope of
about 7.5%. There is an existing public storm drain system in NE 4th PL which
flows south to a storm vault in the Orcas PL NE ROW then west along NE 4th
Street and crossing to the south side of NE 4th street prior to Nile Ave. A
driveway culvert and open ditch fronts the 9031 parcel along Nile Ave NE. The
flow enters a public storm drain system in the SW corner that flows to NE 4th St
then west along the north side of the street. It joins with the south side storm
drain west of Lyons Ave. The combined storm drain eventually discharges to a
detention pond located SW of the site. Drainage ultimately flows to the Lower
Cedar River. An on-site storm drainage collection system with 2 storm water
detention facility Tracts are included and designed per the 2017 RSWDM.
Proposed use: Construct 15 new single-family residence.
Access: Access to the lots will be off NE 4th PL at Orcas PL NE. Orcas PL will be
extended from NE 4 PL to the NW connecting to the existing Orcas Ave NE at
the -9031 parcel north property line. A Public Alley will be included running from
the proposed Orcas Ave NE connecting road to the Pasco Ave NE ROW
termination located at the NE corner of Parcel -9031.

improvements along NE 4th PL and Nile Ave NE. They will also include
extensions of water and sewer mains and the public storm system.

Cut: 17,050 CY and Fill: 5,634 CY.
