C. Project Scope is it sustainable with natural hydrology and sediment transport processes? The beach might not work without high wave exposure and an ongoing source of sand. Does this limit beach location to along the Bay margin? Does this mean regular sand re- nourishment? Should the e beach be pan of a sediment- balanced option; say a channel- marsh -and- _' island complex that includes kayak "trails "? 7,11;" ' zc t $ r - How difficult will it be to secure permits? There would still be Corps amt ,rs -.,t. and BCDC permit requirements, but if we can add a wildlife w4pi • r .:1' ..,- enhancement, say tidal marsh or managing islands for breeding birds, thc permitting may be simpler and less expensive. What will it cost to implement/maintain? The revised alternative could be designed to be largely self - sustaining with natural physical processes, avoiding maintenance dredging and minimizing the need for expensive ongoing management. Does it generate revenue? A concessionaire could manage the beach and kayak rentals under City license? Could this pay for all or significantly • offset operating costs? 3. Technical and Regulatory Opportunities and Constraints . rr, ^. In ESA's 2007 Opportunities and Constraints Analysis, we note that in most ` '" ' i of the action area shared by both the Basin and the DMMS, the full weight of _�—.- _i coastal regulation comes into play and receives: protection by Section 404 of a:. t i y a the Clean Water Act under the jurisdiction of the US Army Corps of tis , .�. Engineers'(Corps), so that any disturbance would require consultation and k ;w' , F permits from the Corps, and through the Corps with thc U.S. Fish and ` = ' ) - ' e" �,. . — Wildlife Service (USFWS). In addition, the State Water Resources Control gip.. -. a rx _ Board (SWRCB) must certify that a Corps permit action meets state water r :',.- e,> — c l."'•1 quality objectives (Section 401, Clean Water Act), so consultation and permits from the RWQCB would also be necessary. Others likely involved would be the Bay Conservation and Development Commission (BCDC), State Lands Commission, Department of Fish and Game, and thc Bay Area Air Quality Management District (BAAQMD). Regulatory issues are daunting, with multiple players whose missions are rarely the same for moving forward with a successful alternative. The team will look towards giving each alternative some attributes of positive water quality improvement or biological resource enhancement, so that thc final preferred alternative is self- mitigating. For example, a series of small "islands" in the Basin would be breeding bird and waterfowl loafing and refuge sites and provide a miniature archipelago for kayaks and dinghy sailors to navigate.
