SECTION 5 <br />Alternatives for Future Use of the DMMS <br />Three Harbor Basin alternatives are being considered in this study, along with the No Action <br />alternative. All Harbor Basin alternatives propose to eventually discontinue use of the City's <br />Dredged Material Management Site (DMMS) for temporary drying and storage of dredged materials <br />from the San Leandro Harbor because of the high cost of this disposal method. <br />This section provides options specific to future use of the DMMS. Initial alternatives for the <br />DMMS were discussed at meetings with City staff on 21 October and 17 November, 2010.

Proposed DMMS alternatives <br />are: <br />1. Operate as DMMS for other, non -City dredge disposers <br />2. Shorebird habitat enhancement <br />3.
