The County reviewed a dredging assessment.
Correspondence covers depth, petitions, surveys, rock removal, cost-sharing, and disposal. In its April 3, 2007 letter for PID 001359, Public Works declined to proceed with the proposed navigational-dredging assessment, citing spoil concerns, legal and risk-management advice, and anticipated costs.
The $2.9 million preliminary estimate describes that historical scope. The letter offered completed technical work to the association for an independent effort.
Technical context and sources
The correspondence discusses historical arsenic findings; the underlying laboratory reports are still needed. The County's historical classification of the proposal as non-drainage does not establish today's canal function or obligations.
