Engineer's Report FY 2010/11 City of San Leandro Heron Bay Maintenance Assessment District No. 96-3 B. Mitigation and Monitoring 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. For Fiscal Year 2010/11 a monitoring report will be prepared by a consultant and funded by the District. C. District Reserve Fund 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. D. Capital Improvement Projects Spartina The Spartina removal project continues with some minor post eradication work. Major eradication is complete; spraying of stubborn patches is all that occurred in fiscal year 2009/10 and is all that is anticipated for fiscal year 2010/11.The District has expended $94,000 on this project of which $30,299 has been reimbursed by a grant managed by the California Coastal Conservancy. An additional reimbursement of $60,000 has been requested but not yet been processed. This year's expenditures are expected to be less than $10,000. Further reimbursements from the California Coastal Conservancy may occur. Levee Repair 2009/10 This project was initiated to repair non-emergency damage to the levees that occurred during the winter of 2005/06. The construction phase of the levee repair project is complete, final paperwork and invoicing for grant funds will occur this summer. The District has expended $100,000 toward this project which is expected to be reimbursed by a grant from the Federal Emergency Management Agency. Levee Maintenance 2014/15 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 are funds available, the District will contribute to the account each year. When sufficient funds have accumulated City staff, working on behalf of the District, will obtain permits and bids for the work and then contract for construction of the work. Any unused funds will be returned to the District. '~ ~~~~ I Page 5 Findr-Gadl $8nti~e8
