Central
Coast Blue
ONE COMMUNITY.
ONE WATER.
ONE FUTURE.
Central Coast Blue is a regional water
reuse project that will create a new, local
water supply and protect the Santa Maria
Groundwater Basin from seawater intrusion.
A partnership between the cities of Arroyo
Grande, Grover Beach, and Pismo Beach,
this collaborative, multi-phase effort will
benefit Southern San Luis Obispo County
for generations to come.

County relies on three water
sources to meet the
community’s diverse needs.
However, prolonged drought and
changing environmental
conditions have dramatically
impacted these sources.
