The Septic Overlay Map tool will provide information on whether a property falls with the area requiring an advanced septic system for new construction.
To show the overlay of areas required to use advanced septic open the tab named “Layer” and then check the “Indian River Lagoon” box. The sliding bar will adjust the transparency so that users can see the property underlying the overlay boundaries.
This GIS map is a quick reference tool and not the sole determination for the type of septic that will be required. For properties partially covered by the overlay, they may still need a survey to show that a proposed septic system falls in or outside the boundaries.
