County Data Read · Trailing 12 Months

What the Data Shows in St. Johns County

The trailing 12 month FDEP public notice record for St. Johns County holds 5 sanitary sewer releases and 54,000 gallons of reported release volume. St. Johns County lands at number 28 of 38 counties for reported volume. One event accounts for 54,000 gallons, the largest in the St. Johns County window. St. Johns County last appeared in the notice record on August 17, 2026. A low count still marks the St. Johns County basins worth watching. St. Johns County is predominantly newer construction, with US Census ACS housing age estimates placing only 14.7% of 127,144 housing units before 1980. That puts the typical St. Johns County structure near 21 years old. Younger construction still warrants CCTV pipeline inspection in St. Johns County, since defects there are installation related.

St. Johns County took only 26.1 inches over the trailing 12 months in NOAA precipitation data (92% coverage). A dry window understates risk, because St. Johns County never saw the groundwater that exposes infiltration and inflow. EPA ECHO carries no active Clean Water Act enforcement in St. Johns County, which keeps work on a planning footing. Because St. Johns County lies in Northeast Florida, the fair comparison set is Alachua and Baker counties. Statewide capability reaches St. Johns County, with crews mobilized to the county and held until the work is documented.
