MEMORANDUM
DATE: November 1, 2017
TO: City of Renton
FROM: Jeff Schramm
SUBJECT: Submittal for the proposed
East Valley Road-Donovan Brothers Development
TENW Project No. 5429
This memo transmits the draft TIA for the proposed East Valley Road-Donovan Brothers project, and also
summarizes the updated trip generation calculation for the purpose of documenting a comparison of the
current project proposal to what was analyzed in the draft TIA dated May 12, 2017.
The current project proposal includes a 32,500 square foot (SF) lumber store, consistent with what was
analyzed in the draft TIA dated May 12, 2017. The prior project proposal assumed the existing Skyway
Towing and MiltÊs Trucking & Excavating would be removed, while the existing Lumber Market would remain
with the proposed project. Based on the latest site plan, the existing Lumber Market will be removed with
the proposed project.
By removing the existing Lumber Market, the existing trip generation credit will increase, therefore reducing
the net new trip generation associated with the proposed East Valley Road-Donovan Brothers project. Shown
below in Table 1 is a comparison of the trip generation estimates based on the latest site plan compared to
what was analyzed in the draft TIA dated May 12, 2017.
Table 1
East Valley Road-Donovan Brothers – Trip Generation Comparison
May 2017 Draft TIA Current Proposal
Time Period In Out Total In Out Total
Weekday Daily 563 563 1,126 538 538 1,076
Weekday AM Peak Hour 45 20 65 40 16 56
Weekday PM Peak Hour 61 66 127 61 61 122
As shown in Table 1, the trip generation associated with the current project proposal is less than what was
assumed in the May 2017 draft TIA. Based on this information, the findings and conclusions in the May
2017 draft TIA remain valid and can be considered conservative since the net new trip generation is less.
Transportation impact fees will be based on the size of the building and type of tenant(s) at the time of building
permit issuance.
If you have any questions regarding the information presented in this memo, please contact me at (425) 250-

I have reviewed the application for the Compton Lumber at 2940, 2960, and 2980 East Valley
Road (APN(‘s) 3023059091, -9096, -9098, 9099) and have the following comments:
EXISTING CONDITIONS
The site is approximately 5.85 acres in size and is square in shape. The existing site is mostly
impervious and developed with commercial buildings. There is an existing Category III wetland
located on the eastern border of the site. Site topography is generally flat with a slight slope
running north to south.
Water Water service is provided by City of Renton The site is in the Valley service area in the
196 hydraulic pressure zone. There is an existing 12-inch City water main located in
East Valley Road (see Water plan no. W-0304) that can deliver a maximum total flow
capacity of 5,000 gallons per minute (gpm). The approximate static water pressure is
75 psi at the elevation of 18 feet. The site is located outside of an Aquifer Protection
Area.
Sewer Wastewater service is provided by the City of Renton There is an existing 8-inch PVC
wastewater main located in East Valley Road (see City plan no. S-0200).
Storm There is an existing storm drainage system in East Valley Road (see City plan no. R-
1999). There is an existing private storm drainage system located on the subject
parcel(s) which drains to the public drainage system in East Valley Road. Surface run-
off from the site appears to drain to the abutting wetlands as well as to the public
drainage system in East Valley Road.
Streets East Valley Road is a Collector Arterial Street with an existing right of way (ROW) width
of 85 as measured using the King County Assessor’s Map. Current street frontage
improvements include curb and gutter and a 6-ft sidewalk on both sides of the street.
The site borders State Route 167 (SR 167) on the east property line. WSDOT has
identified, in their long-range planning programs for I-405 and SR-167, a direct access
connection to and from the south at SW 27th Street, which the City supports. Applicant
