removal from the DMMS will cost another $7,500,000. Unfortunately, the $1,700,000 that the City was able to obtain through federal earmarks cannot be used towards this endeavor as it exceeds the scope of the funded project in both size and quantity. Over the last two years, the Shoreline-Marina Committee has been studying and contemplating the long-term viability and sustainability of the Harbor in its current state and structure. As part of its review, the Committee commissioned a hydrology study to ascertain the long term consequences of not dredging the Marina. Analysis The hydrology study concluded that the siltation rates in the Marina are dynamic, ranging from zero to fourteen inches per year. It also concluded that the marina bank would ultimately turn into mud flats with flushing action from tides that would drastically minimize odors. The San Leandro Marina is subject to extreme tidal fluctuation, ranging from minus two feet to plus nine feet. Without dredging, in a couple of years, boats would only be able to leave and enter during higher tide periods. Given all the facts, the City has three options for the Marina, which are outlined below: OPTION I - Do nothing. • This option would entail abandoning the dredging of the Harbor/Channel, ceasing any future improvements to the Marina infrastructure, and closing the boat launch ramp and the Harbor. This option would save the cost of dredging, removing dredge materials from the DMMS and future improvements to the Harbor infrastructure. Savings over the next five years would be an estimated $24,000,000. However, there would be a cost for ultimately dismantling the Harbor and paying back all outstanding debts to the State and the City's general fund. OPTION II -Keep Harbor and boat launch ramp operational as it is today. • This option would involve dredging the Channel and berthing areas to the past maintenance depth of seven feet or more. It would also entail making all capital improvements necessary to ensure the continued operation of the Harbor facilities well into the future. Costs of dredging and material removal from the DMMS would be about $10,500,000 during the next of couple of years. An additional $5,000,000 to $7,000,000 would need to be spent just four years thereafter for the same purpose. None of these costs would be eligible to be defrayed by the current COE allocation. Hence, the City would be responsible for all expenses. The separate cost of improving the decrepit Harbor facilities, estimated at about $6,000,000, would also be borne by the City. In addition, all debts currently owed to the City and State would also be due. OPTION III -Convert the Marina to a community recreational area only for such uses as: small boats and crafts; beach play areas; and water trails.
