City of San Leandro 2026/2027 Heron Bay MAD 96-3 Page 5 B. Mitigation and Monitoring Mitigation of the Heron Bay project was accomplished by re-construction of marshlands, tidal marshlands, and upland or high ground for wildlife habitat. In order to verify that the habitat was healthy, and in order to identify maintenance requirements, a monitoring report was prepared annually and submitted to the involved regulatory agencies for the first 10 years after marsh re-construction, at which point the restoration of the marshlands was considered a success and formal monitoring has ended. C. District Reserve Fund The goal of the District is to maintain a Maintenance Reserve Fund in the amount of $300,000 to fund capital improvements and unexpected or emergency repairs. With the current scheduled Capital Improvement Projects, withdrawals from the reserve fund are anticipated for the coming fiscal year. D. Capital Improvement Projects Shoreline Trail Repairs Purchase and install rock along the shoreline of the maintenance area to stabilize the shoreline trail after storm damage in December 2024 and to prevent future erosion from high tide due to sea-level rise. Hydrology Study A comprehensive study of the marshlands’ hydrology has not been conducted since the start of the re-construction in the mid-1990s. To ensure the optimal health of the tidal community, as well as the marshlands’ connectivity with Estudillo Channel and San Francisco Bay, a new hydrological study is recommended. This study is funded in FY 24/25 and will be finalized in FY 26/27. Long Beach Restoration Design Project City will work on a comprehensive study and apply for grant funding for the restoration of Long Beach, a sandspit that provides wildlife habitat for California wildlife and marsh. Failure to restore and protect Long Beach from erosion and breaches may result in the loss of favorable habitat (sandspit and marsh) for endangered and threatened species. The City plans to hire a consultant to seek and write grants for the funding of the construction of the Long Beach Restoration Project. Interpretive Signs The interpretive sign project will be on hold until further notice pending funding availability. Design and construct 6 interpretive signs along the Heron Bay trail to replace existing signs that are in disrepair. Content and graphics to be recreated from photographs and printed onto new panels for installation on new sign structures. Exhibit A Resolution No. 2026-076 Page 8 of 32
