Summary
Building or altering a stormwater system in Indian River County requires an Environmental Resource Permit. Under Fla. Stat. §373.413, the St. Johns River Water Management District permits these systems so runoff does not harm the Indian River Lagoon.
Except for the exemptions set forth herein, the governing board or the department may require such permits and impose such reasonable conditions as are necessary to assure that the construction or alteration of any stormwater management system, dam, impoundment, reservoir, appurtenant work, or works will comply with the provisions of this part and applicable rules promulgated thereto and will not be harmful to the water resources of the district.
Full Breakdown
In Indian River County, constructing or altering a stormwater management system triggers the Environmental Resource Permit program. The St. Johns River Water Management District (SJRWMD) administers ERPs under Fla. Stat. §373.413 and Chapter 62-330, Florida Administrative Code. Because runoff from Vero Beach, Sebastian, and the barrier-island communities drains into the Indian River Lagoon, a nationally significant but nutrient-stressed estuary, projects must capture and treat runoff before it reaches the lagoon's seagrass. The county's stormwater ordinance and its fertilizer ordinance, with a summer rainy-season blackout on nitrogen and phosphorus, layer nutrient controls on top of the ERP. Sites disturbing an acre or more also need federal NPDES coverage.
