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, a one-way northbound alley James Street and 216 Ave N. The existing site is was formerly occupied by a US Post Office which is being relocated into the Phase 1 development. Phase 2 includes a four story 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. Garage access will be shared with the Phase 1 access off of 2"d 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 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. 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. TS1on Solutions, Inc. Table 1.
