<br />City of San Leandro Heron Bay Maintenance Assessment District No. 96-3 Page 5 <br /> <br />B. Mitigation and Monitoring <br />Mitigation of the Heron Bay project was accomplished by re-construction of marshlands, <br />tidal marshlands, and upland or high ground for wildlife habitat. In order to verify that the <br />habitat was healthy, and in order to identify maintenance requirements, a monitoring report <br />was prepared annually and submitted to the involved regulatory agencies for the first 10 <br />years after marsh re-construction, at which point the restoration of the marshlands was <br />considered a success and formal monitoring has ended. <br /> <br />C. District Reserve Fund <br />The goal of the District is to maintain a Maintenance Reserve Fund in the amount of <br />$300,000 to fund capital improvements and unexpected or emergency repairs. With the <br />current scheduled Capital Improvement Projects, withdrawals from the reserve fund are <br />anticipated for the coming fiscal year. <br /> <br /> <br />D. Capital Improvement Projects <br />Tide Gate Repair <br />Repairs to tide gates are completed by contract on an as-needed basis to assure their <br />proper operation. Repairs include; reconnecting the flap gates and the frames, replacing <br />rotted sections of the drain pipes, reattaching the screen latch connections, replacing <br />damaged/corroded screen bars and screens, and installing associated stainless-steel <br />lubrication tubings. In 2022, a comprehensive inspection of all tide gates was performed <br />by the City’s contractor, in which significant repair/replacement work was identified. <br /> <br />Hydrology Study <br />A comprehensive study of the marshlands’ hydrology has not been conducted since the <br />start of the re-construction in the mid-1990s. To ensure the optimal health of the tidal <br />community, as well as the marshlands’ connectivity with Estudillo Channel and San <br />Francisco Bay, a new hydrological study is recommended.
