manage, as part of it’s jurisdiction, an area that appears hydrogeologically interconnected with (and represents a source of inflow to) the Sonoma Valley B118 basin.
assessed to landowners within current Sonoma Valley B118 basin by spreading out costs over larger base of potential payers.
(estimated at $30,000 to $60,000) is not included in GSA’s FY16/17 Budget.
initiate development of GSP.
affected by modification may oppose the modification request, which would lead to uncertainty in DWR’s acceptance of the request.
connection between basins and complex geologic conditions create uncertainty as to whether DWR will accept technical basis for boundary modification.
Sonoma Valley B118 basin could potentially increase long-term costs to the GSA (associated with monitoring and managing this area).
