Consider and take action on a resolution authorizing an agreement with the Bay Area Coastal Protection Alliance (BACPA) for the completion of a financial study related to a regional coastal barrier system in an amount not to exceed $7,500 (City Manager)

Bolivar Roads and San Luis Pass could be protected by large moveable flood gates that would be closed in the hours before landfall of the storm but would not impact shipping or the ecology of the bay when open.

BACPA has sent a proposal to all cities in th...
