Service Area
Erosion Control & Stormwater Services in Seminole County, FL
Seminole County is LES's home market — the company is headquartered in Sanford, the county seat. The county sits along the I-4 corridor between Orlando and the Wekiva and St. Johns River systems, with development pressure concentrated around Sanford, Lake Mary, Oviedo, and Winter Springs.
Permitting Environment
Construction stormwater compliance in Seminole County operates under the county's MS4 (Municipal Separate Storm Sewer System) permit program in addition to FDEP's NPDES Construction Generic Permit for sites over one acre of disturbance. Seminole County's Watershed Management and Public Works divisions review site stormwater plans for new development and redevelopment.
Drainage & Stormwater Considerations
Much of the county drains toward Lake Jesup, Lake Monroe, and the St. Johns River, with the western portion of the county falling within the Wekiva River basin — a designated Outstanding Florida Water with heightened protection standards. Sandy, well-drained soils dominate, but flatwoods and wetland-adjacent parcels are common, which makes proper inlet protection and sediment basin sizing especially important on sites near these systems.
Development Activity
Seminole County continues to see active residential infill and redevelopment along the I-4 corridor, with Sanford's historic downtown and waterfront seeing renewed commercial interest alongside ongoing single-family and townhome development in Lake Mary, Oviedo, and Winter Springs.
