How permitting and review work in Santa Rosa
Santa Rosa Water runs the Regional Water Reuse System, once known as the Subregional System. Its Laguna Treatment Plant treats wastewater from Santa Rosa, Rohnert Park, Sebastopol, Cotati and the South Park County Sanitation District.
Most of the plant's recycled water goes to farm and urban irrigation and to the Geysers Recharge Project, which uses it to make geothermal power.
Santa Rosa's main drinking water source is the Russian River, delivered by Sonoma Water.
The North Coast Regional Water Quality Control Board covers Santa Rosa. It issues waste discharge requirements and the area's municipal stormwater permit.
New development follows the Storm Water Low Impact Development Technical Design Manual that Santa Rosa shares with Sonoma County. Projects that need permanent stormwater measures submit a stormwater plan with their planning application.
Sites outside city limits go through Permit Sonoma, the county's planning and permit agency.
