March 19, 2015
Update: August 1, 2016
This technical memorandum updates the March 19 document of the same name. Please also find attached,
a copy of the updated City of Edmonds Traffic Impact Analysis Worksheet. The following includes a brief
description of the project and trip generation forecast.
Description of the Proposal:
The proposed Edmonds Mixed -Use is Phase 2 of the redevelopment the Edmond Post Office site. The site
address is 201 Main Street. Specifically, the site is located on the south portion of the larger site which is
bound by Bell Street, an alley, James Street and 2"d Ave N. The existing site was occupied by an 8,632 sq. ft.
US Post Office.
Phase 2 includes a four story (mid -rise) building with a parking garage, approximately 7,500 of street level
commercial space and 26 multifamily apartment units located on the top two stories.
The Phase 1 parking garage will be expanded to accommodate parking for Phase 2. Onsite parking access
will be off of 2nd Ave N. Phase 2 is anticipated to be built out by 2016-2017.
The May 8, 2014 Traffic Impact Analysis Worksheet and corresponding technical memorandum
documented both trip generation and sight distance for Phase 1. Sight distance at the access was
determined to be sufficient.
Phase 1, which is current under construction, is being completed with 43 multifamily apartment units and a
new space for the post office.
Trip Generation Forecast:
Table 1, attached, summarizes the number of trips forecast by the Phase 2 development. Data from the ITE
Trip Generation Manual, 9th Edition (2012) was used to forecast trip generation for the proposal. Onsite
trip sharing between the proposed uses and Phase 1 is anticipated to be minimal.
Phase 2 is projected to generate fewer trips than the existing land use. With the net new trip generation
being negligible, Phase 2 is not required to submit traffic impact fees for this proposed change in use.

Mid -Rise Apartment
Description
Mid -rise apartments are apartments (rental dwelling units) in rental buildings that have between
three and 10 levels (floors). Apartment (Land Use 220), low-rise apartment (Land Use 221) and high-
rise apartment (Land Use 222) are related uses.
Additional Data
The peak hour of the generator typically coincided with the peak hour of the adjacent street traffic.
The sites were surveyed in the late 1980s in Montgomery County, Maryland.
