§ 27-520. Erosion and sediment control.

(a)

Where the natural cover or topography of the site has been altered or otherwise disturbed, all necessary erosion and sediment control measures shall be used to retain sediment on-site and to prevent violations of water quality standards as specified in Chapter 62-302, F.A.C. The developer must provide an erosion and sediment control plan that is based on the appropriate best management practices (BMPs) for erosion and sediment control as described in the State of Florida Erosion and Sediment Control Designer and Reviewer Manual (June 2010) and the Florida Stormwater, Erosion, and Sediment Control Inspector's Manual (latest edition). These rules and manual are hereby incorporated by reference, but shall not supersede the city's ordinances.

(b)

All land disturbing activities: Erosion and sediment control and tree protection measures shall be installed prior to any other construction activity and maintained until permanent groundcover is established. The escape of sediment from the site shall be prevented by the installation of erosion and sediment control BMPs prior to, or concurrent with land disturbing activities. Erosion control measures will be maintained at all times. If full implementation of the plan does not provide for effective erosion control, additional erosion and sediment control measures shall be implemented to control or treat the sediment source by the contractor as needed. Land disturbing activities shall minimize the extent of the area exposed at one time and the duration of exposure. Effective erosion control measures shall be implemented to prevent off-site damage at all times during land disturbing activities. Perimeter control practices shall protect the disturbed areas from off-site runoff and to prevent sedimentation damage to areas below the development site. Low runoff velocities shall be maintained. All disturbed areas shall be stabilized immediately after final grade has been obtained.

(c)

Land disturbing activities of one (1) acre or more: All projects disturbing one (1) or more acres of land, or, in for projects within a common plan of development or sale such as a subdivision cumulatively disturbing one (1) or more acres, must obtain coverage under FDEP's Generic Permit for Stormwater Discharge from Large and Small Construction Activities, also known as a construction generic permit (CGP) pursuant to Ch. 62-621.300, F.A.C. The notice of intent (NOI), any correspondence, the acknowledgement letter granting coverage under the CGP, a copy of the CGP, erosion control plans, stormwater pollution prevention plan (SWPPP), and all completed inspection forms and other documentation required by the CGP shall be available at the site at all times and made available to the city manager, city inspectors, or designee until land disturbing activities have been completed. The contractor shall have at least one (1) person on-site at all times during work activities certified through the Florida Stormwater, Erosion and Sedimentation Control Inspector Training Program.

(d)

Land disturbance activities that encounter work interruptions of fourteen (14) days or more shall stabilize all disturbed areas.

(e)

No certificate of occupancy shall be granted until all disturbed areas have final stabilization activities completed.
