~Is.~~i~~~s MITIGATION STRATEGIES Traffic mitigation measures that would be required with the project opening by 2007 include: Construction of the Patterson Street extension and underpass of HWY. 99W and the UPRR facility. This facility consists of extending Patterson Street north from Broadway and realigning 8t" Avenue to "tee" into Patterson Street. The extension would pass under HWY. 99W and the UPRR alignment to join the extension of Avenue "A" at approximately the location between the existing EWEB steam plant and the substation. The existing at-grade railroad crossing of 8t" Avenue/Hilyard Street would be removed with this improvement. • Construct the Patterson Street extension with two-way access from Broadway to the extension of Avenue "A", with the installation of a traffic signal located at the Broadway/Patterson Street intersection. This improvement should be implemented to allow for better traffic operations/circulation and better egress to the south. The improvements at the Broadway/Patterson Street intersection consist of relocating the crosswalk previously planned on the west side of the intersection to the east side of the intersection, and reconfiguring the southbound approach lanes to consist of a dedicated left turn lane and a shared through right turn lane. The eastbound approach to the Broadway/Patterson Street intersection is to consist of two through lanes and two dedicated right turn lanes plus a dedicated left turn lane. In addition, the crosswalk located on the west side of the intersection should be relocated to the east side of the intersection to shorten the amount of time necessary to cross Broadway and allocate additional green time to the eastbound/westbound through movements. Proper signage should be implemented for the southbound left turn lane that would indicate "Left Turns Yield to Peds" (ODOT signage OR17-6). Figure 6 shows the "no-build" and proposed mitigated geometry at this intersection. By shifting the crosswalk from the west side of the intersection to the east side of the intersection the crossing distance is shortened by approximately 24 feet. This equates to approximately six additional seconds that could be allocated to the east/west through movements. • Construction of Avenue "A" from the southeastern edge of the EWEB site to Agate Street just north of the UPRR tracks as identified in the Riverfront Research Park Master Plan. This would be atwo-lane roadway with on-street parking and sidewalks. The construction of Avenue "A" would provide a reliable access to the south (no closures due to trains) from the project site that a hospital facility requires.
