Roberts Short Plat Project Narrative
Project Information
Name: Roberts Short Plat
Site Area: 54,893 SF (1.26 acres)
Site Address: 3XX Toledo Ave SE
(unaddressed)
TPN: 1463400052
Zoning: R-4 (for parcel and
surrounding parcels)
Existing Conditions
The project site currently consists
of a horse arena and stables and
is vegetated with grass, trees, and
shrubs. Per City of Renton Online Mapping, there are no critical areas on the site although a
small portion of the site is classified as regulated slopes at 15-25%. The soil type is
Alderwood Gravelly Sandy Loam, 8-15% (AgC). The parcel generally slopes down from the
northeast to the southwest at an average grade of approximately 8%. Existing stormwater
runoff sheet flows to an existing stormwater system within the Toledo Avenue SE (154th
Avenue SE) Right-of-Way.
Proposed Development
The property owner is proposing to subdivide the existing parcel into 4 single-family lots and
a half-street ROW dedication. All existing structures will be demolished. The new lots will
access off Toledo Avenue SE via a proposed half-roadway connection. Water connections
via Water District 90 are available at or near the property boundary and the sewer will tie into
the existing system located within the ROW of Toledo Ave SE via the manhole located near
the southwest corner of the parcel. An existing stormwater catch basin is located within the
ROW of Toledo Ave SE at the southwest corner of the existing parcel where the proposed
project will connect.

Zoning & Density
The property is zoned R-4 with a base density of 4 units per acre. The original parcel is 54,893
square feet (1.26 ac). The allowed maximum density is 1.26 x 4 = 5.01 residential units. This
proposal will produce 4 single-family homes per R-4 zoning regulations. See Site Plan for
reference.
The estimated construction costs will be in line with projects of similar size at about
$500,000; the project will propose a balanced amount of cut/fill for the earthwork.
The location and description of significant trees will be provided with the Preliminary Short
Plat application package. The project will comply with the 30% Tree Retention
requirements.
Utilities
The short plat will be served by Water District 90 for potable water and the City of Renton for
sewer service. Stormwater management will be in accordance with the City of Renton
Surface Water Design Manual with a focus on utilizing infiltration, rain garden (frontage) and
onsite Flow control BMP’s to the maximum extent possible.
Tree Retention
In accordance with the new City of Renton Tree retention codes, the project will retain 30%
of the existing trees onsite and meet the tree retention credits per acre.
