Subject: Edmonds Mixed -Use /Edmonds Post Office Site Development— Phase 2
Attachment to Traffic Impact Analysis Worksheet
March 19,2015
This technical memorandum isanattached k/the Traffic |mpactAna|ysisVVorksheetandprovidesabrief
description ofthe development proposal and trip generation forecast,
Description of the Proposal:
The proposed Edmonds Mixed -Use bPhase 2ofthe 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, a one-way northbound alley James Street and 2nd Ave N. The existing site
is was formerly occupied by a US Post Office which is being relocated into the Phase 1 development.
Phase 2includes afour story building with aparking garage, approximately 750OVfstreet level
commercial space and 26 multifamily apartment units located on the top two stories.
The Phase 1 pat -king garage will be expanded to accommodate parking for Phase 2. Garage access will be
shared with the Phase 1 access 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 anew space for the post office.
Trp Generation Forecast:
Table 1summarizes the number nftrips forecast bvthe Phase 2development. Data from the ITE Trip
Generation Manual; 9th Edition (201.2) was used to forecast trip generation for the proposal, Trip
sharing between the proposed uses and Phase 1 is anticipated to be very minimal.
Phase 2 is forecast to generate 323 weekday daily trips and 23 PM peak hour trips.

7. MITIGATION RECOMMENDATIONS
State recommended measures and fees required to mitigate project specific traffic impacts. Traffic
impact fee shall be calculated from the Edmonds Road Impact Fee Rate Study Table 4 (attached)
and as identified in ECDC 18.82.120, except as otherwise provided for independent fee calculations
in ECDC 18.82.130.
❑ CHANGE IN USE
Fee for prior use shall be based on fee established at the time the prior use was permitted. If the
previous use was permitted prior to the adoption of Ordinance 3516 (effective date: 09/12/04),
the 2004 ECDC 18.82.120 impact fee shall be used.
