Mitigation of the Heron Bay project was accomplished by construction of wetlands, tidal wetlands, and upland or high ground for wildlife habitat. In order to verify that the habitat is healthy and in order to identify maintenance requirements a monitoring report is prepared annually. A Maintenance Reserve Fund is maintained by the District in the amount of $300,000 to fund capital improvements and unexpected or emergency repairs. There have not been any withdrawals from the reserve fund this past fiscal year and none are anticipated for the coming fiscal year. �� • -MWTITIJIVIV=l Levee Maintenance The nature of the levees that protect the Heron Bay marshland is such that they require periodic maintenance; specifically, the heavy stone rip rap that prevents erosion shifts, settles, or washes away and needs to be replaced. This work is most efficiently done by an outside contractor in large quantities. In fiscal year 2009-10 the Heron Bay Levee Maintenance account was established. Provided that there were funds available, the District contributed to the account each year. To date, the District has contributed $372,000 towards the maintenance of the levee, which appears sufficient to address areas of the levee City staff has identified that need repair. Any unused funds will be returned to the District. City staff, through a consultant, has obtained permits from various regulatory agencies that will allow repair of levee sections identified for maintenance. City staff on behalf of the District, will bid and construct a repair project in the summer of 2019 within permit prescribed guidelines. Levee repairs and related work can only be accomplished in the Fall between September and end of December. The project is currently estimated to cost $350,000. Trail Maintenance City staff will periodically hire a contractor to complete pavement repairs on sections of the trail where tree roots have damaged the asphalt. The work will involve digging out small sections of pavement, trimming back tree roots and installing new asphalt patches. Shoreline Signs, Parking and Accessible Walkway In conformance with the City's updated permit with the San Francisco Bay Conservation and Development Commission (BCDC), wayfinding signage along the Bay Trail will be repaired since the existing signage has been worm by weather and sun -exposure. Tide Gate it City staff completes repairs to tide gates on an as -needed basis to assure their proper operation. Repairs include; reconnecting the flap gates and the frames, replacing rotted sections of the drain pipes, reattaching the screen latch connections, replacing damaged screen bars and screens, and installing associated stainless-steel lubrication tubings.
