Sumter County, FL Environmental Rules: Erosion Control (2026)

Section 13-907, 'Soils,' splits erosion control into an agricultural half and a development half. ' Subsection (b) is the operative rule for construction: paragraph (1) states that any land disturbing activity that results in a change in the natural cover or topography and that may cause or contribute to sedimentation and erosion shall be done with due regard to controlling and minimizing erosion and sedimentation, and only after approval by any local, state or federal agency having jurisdiction. That ties every grading or clearing permit to whatever additional sign-off the Southwest Florida Water Management District, FDEP, or another agency separately requires for the same disturbance.

Paragraph (2) then sets the ground-cover fallback for a disturbed site: where it is not possible to retain existing natural ground cover, the site must get acceptable ground cover, meaning grass species normally grown in Sumter County, seeded, sodded, plugged or sprigged, except that sod or ground-cover plants are required on any slope steeper than 4:1. Ground covers other than grass have to reach reasonably complete coverage within one year after planting, and every replacement ground cover must be watered until it is firmly established, so the obligation does not end once seed hits the dirt. Development Services checks these standards during site plan and grading review, applied alongside the county's drainage and stormwater management design standards in article VII.
