Grant-funded beach-restoration project at Black East Pasture moves to bid; borrow volume cut dramatically
Summary
Tiburon staff reported that a Coastal Conservancy-funded beach-restoration at Black East Pasture (Ducky's Pasture) will go to bid in late May. Project funding covers construction, and engineers reduced on-site borrow from 925 to about 140 cubic yards, securing outside material to make up the difference.
Town staff updated the Post Commission on a grant-funded shoreline restoration project at Black East Pasture (Ducky's Pasture) and related nearby shoreline work. The project, fully funded by state grants and project partners, seeks to remove decades-old asphalt, rebuild a sand-and-gravel beach profile, add sediment-retention elements (including a log backstop) and install vegetative test cells to reduce ongoing erosion and improve beach habitat.
Staff said the project team substantially reduced the amount of material the project would borrow from a local delta bar: the originally permitted 925 cubic yards has been reduced to roughly 140 cubic yards and additional material secured off-site to avoid larger borrow volumes. To give scale, staff noted 140 cubic yards is about a 6-inch layer spread across a full-size tennis court.
Key procurement dates: the town planned to advertise the work May 21, hold a mandatory bid walk on June 3, accept bidder questions through June 11, and have bids due June 18. Town Council is scheduled to consider awarding the contract on Aug. 5; construction is expected to start in September and finish by late October. Staff emphasized that the project is fully grant-funded (conservancy and related grants) and that no town capital funds are required for construction.
Project monitoring is planned to follow construction; the approach will be monitored for several years as a pilot for nature-based erosion control in other suitable locations along the peninsula.
