Why Regional Planning?

CALFED water quality goals can’t be accomplished in the Delta alone

Regional coordination and integration required to access funding sources

Funding provided by CALFED Drinking Water Quality Program to initiate planning


5

Objectives

Create a partnership to initiate integrated regional water quality planning

Identify initial regional investment strategies

Position the region to successfully compete for funding

Challenges

Cost & effectiveness information for many strategies lacking

Making link between WQ strategies for Delta/SWP & local supplies

Developing cohesive strategy with priorities that is supported by everyone

Start small & build out Important to work through existing

networks
