The proposed project involves the Phase III extension of the River Path Del Mar (River Path) pedestrian trail in the City of Del Mar (City) along the southern edge of the San Dieguito Lagoon (lagoon). Phases I and II are completed, with Phase I extending northwest of Jimmy Durante Boulevard and Phase II extending southeast of Jimmy Durante Boulevard. Combined, the River Path is generally oriented in a northwest to southeast direction along the lagoon between the railroad tracks near Camino Del Mar and the Lagoon Viewpoint at the Old Grand Avenue Bridge (Grand Avenue Lookout). The River Path provides views of the water and includes informational signage regarding the importance of wetlands and natural resources. The proposed project would complete the River Path by extending the trail southeast of the Grand Avenue Lookout for approximately one-half mile until termination at the City limits near the Crest Canyon Trail. Completion of a formal trail segment that would link the Coast to Crest Trail to the Crest Canyon Trail has been a long-time goal of the City, the City’s Lagoon Committee, the San Dieguito River Valley Conservancy (SDRVC or Conservancy), and the San Dieguito River Valley Regional Open Space Park Joint Powers Authority (San Dieguito River Park JPA). In May 2016, the Phase II River Path section between Jimmy Durante Boulevard and Grand Avenue Lookout opened to the public and a future Phase III extension continuing the River Path to the Crest Canyon Trail was immediately envisioned. In partnership with the Conservancy and the San Dieguito River Park JPA, the City would manage this project from initial design through construction. Construction is anticipated to begin in 2023 for a duration of approximately four months. Following construction of the project, the City would oversee perpetual management of the Phase III extension of the River Path in conjunction with Phases I and II.
