PROPOSALFOR RFP NO.: 23-030 LINCOLN AVENUE PEDESTRIAN PATHWAY, Santa Ana, CA Tetra Tech provided engineering, geotechnical, environmental, permitting, landscaping, surveying and construction support services for this active transportation project. The project was funded in part by ATP state grant funds. The pedestrian pathway runs parallel with Lincoln Avenue west of the existing railroad tracks. The improvements commence at the intersection of Lincoln Avenue and Park Lane, continue north between the back of the residential properties and the railroad tracks, and end at the existing Santiago Trail, under the railroad bridge that crosses Santiago Creek. The improvements included a 12-foot pathway and railroad -approved safety fencing, drought tolerant landscaping, pedestrian lighting, and a trailhead to identify the pathway. When the Lincoln and Fairhaven Avenue railroad crossing was closed permanently several years ago, pedestrian and bicyclist access was also removed. The closure now requires motorized and non -motorized users to travel an additional mile out of the way, causing a substantial impact for non -motorized users. The construction of the project provides active transportation continuity to the Santiago Trail, connects to the existing pedestrian pathway located along the east side of the railroad tracks, and enhances the aesthetics of the area. The connection to the eastern pedestrian pathway provides the ability to traverse to the south back to Fairhaven Avenue. FIRST STREET PEDESTRIAN IMPROVEMENTS, Santa Ana, CA Tetra Tech provided engineering, surveying and construction support services for this sidewalk widening project funded by ATP state and federal grant funds. The project involved the widening of the existing sidewalks along a 1.2-mile portion of First Street between Flower Street and Standard Avenue in the City of Santa Ana. In addition to the sidewalk improvements, the project included retrofitting reconstructing drainage structures including catch basins and parkway drains and installing Green Streets Best Management Practices (BMPs) to improve stormwater quality. Per the Water Quality Management Plan (WQMP) that was prepared for the project, proprietary flow -through filtration systems were installed at select locations throughout the corridor. Due to the limited storm drain systems along the corridor, a BMP could not be installed for each drainage management area. Instead, BMPs were installed at locations throughout the corridor that had opportunities to connect the BMP outlet pipe to a nearby existing storm drain catch basin. These BMPs were oversized to treat the impacted project area runoff as well as additional offsite runoff, which is consistent with Section 2.7.2 of the Technical Guidance Document (TGD) that states 'treatment of comingled off -site runoff may be used to off -set the inability to treat areas within the project for which significant constraints prevent the ability to provide treatment.
