using current RMP protocols • Estimated Cost: $47,000

Option 2:DWR Collaboration and RMP Sampling

Entire Estuary

• Option 1 and additional RMP benthic sampling

• Four RMP sites in each of the five remaining Estuary segment (Extreme So. Bay, So. Bay, Central Bay, Carquinez, and Rivers).

• Estimated Cost: $81,000
