Port Orange, FL Environmental Rules: Erosion Control (2026)

Section 5 of the clearing-and-grading chapter requires every construction site to use city-approved best management practices to keep bare soil from eroding or blowing off-site, consistent with the city's obligations under its NPDES phase II municipal separate storm sewer permit. 5 acres (21,780 square feet) or more of soil must also come with a full erosion and sediment control plan, unless the work is emergency action needed to protect life, property or natural resources. The plan must map protected soils and resources, lay out a construction schedule showing when clearing starts and how long areas stay exposed, and specify seeding mixtures, sod types and fertilizer rates for both temporary and permanent cover.

Design standards cap cut-and-fill slopes at a 4:1 ratio, require bare soil to be stabilized within seven days of clearing or of work stopping, and require seeded areas to establish within two weeks or be reseeded. Soil stockpiles must be covered at the end of every workday, and any site disturbing more than 30 acres must clear and grade in phases sized and located as the city approves. The permittee must inspect its own control measures at least every seven days, or after any half-inch rain event, and document each inspection in writing; the city separately inspects at site clearing, rough grading, final grading and final landscaping milestones, on two working days' notice.

Violating Section 5 is a misdemeanor, with each day of an uncorrected violation counted as a separate offense, and fines are set by city council resolution. A violator also bears the cost of restoring the site to code, and the city can suspend or revoke the development permit and issue a stop-work order for noncompliant work. Once grading is finished, every disturbed area must be seeded and mulched or sodded per the city's standard construction details, and letting erosion continue afterward, through removed or unmaintained vegetation, is itself a code violation.
