PROJECT DESCRIPTION This project will improve the 10th Street NE/NW corridor between B Street NW and Auburn Way North by converting the existing four-lane roadway into a three-lane configuration, consisting of one travel lane in each direction, a center two way left turn lane, and buffered bike lanes. These enhancements aim to improve safety, access, and multimodal mobility. Intersection upgrades include removing the east/west stop control at A Street NE and installing Rectangular Rapid Flashing Beacons (RRFBs) and refuge islands at the north-south crosswalks to improve pedestrian safety. The traffic signal at D Street NE will be modified to match the updated cross section, and the entire corridor will receive a grind and overlay. In conjunction with the transportation improvements, the project will replace approximately 58 feet of existing 8-inch storm sewer with a new 12-inch pipe to increase drainage capacity. Existing catch basins will be preserved unless their replacement is necessary for pipe replacement. SCOPE OF WORK The design contract will include project management, environmental approvals and permitting, cultural and historical survey, preparation of contract plans, specifications, and estimates at the 30%, 90% and final review levels; “over-the-shoulder” reviews between the 30% and 90% review levels, and bidding/construction assistance.
