Erosion Control

When land is disturbed at a construction site, the erosion potential increases. Ground cover on an undisturbed site naturally protects the surface and removal of that cover increases the site’s susceptibility to erosion.

Even though construction requires that land be disturbed and left bare for periods of time, proper planning and use of erosion prevention measures can reduce the impact of human-induced erosion, including the movement of soil off the site and its impact on water quality.

Erosion Control Only Permit

To begin grading or excavation before the Site Development Permit is approved, you may apply for an Erosion Control Only Permit. Application is separate from the Site Development Permit and requires three sets of erosion control plans.

Before applying for an Erosion Control Only Permit, you must have the Service Provider Letter, Land Use Approval and any required Corps of Engineers or Department of State Lands permits. You will also need a preliminary review of site development plans to ensure that revisions will not affect grading, pipe alignments, water quality/quantity facilities or vegetated corridors.

DEQ 1200-CN Erosion Control Permit (sites between one and five acres)

A Department of Environmental Quality (DEQ) 1200-CN Erosion Control Permit is required for construction activities on sites between one acre and five acres of disturbance to control stormwater runoff.  The District and its member Cities act as permit agents for DEQ.  Applicants must submit the required 1200-CN template style erosion control plans before the District may issue Site Development and/or Erosion Control Only Permits or Connection Permit Authorization.  Refer to the DEQ 1200-CN Plan Checklist for submittal requirements.  For general information on the 1200-CN permits, visit DEQ's 1200-CN Construction Stormwater General Permit page.

DEQ 1200-C Erosion Control Permit (sites greater than five acres)

A Department of Environmental Quality (DEQ) 1200-C Erosion Control Permit is required for construction activities on site five acres and larger to control stormwater runoff.  Applicants must submit the required 1200-C forms and erosion control template style plans before the District may issue Site Development and/or Erosion Control Only Permits or Connection Permit Authorization.  The District and its member Cities act as permit agents for DEQ.  At the conclusion of the required 14-day public comment period, DEQ authorizes issuance of the 1200-C Permit.  Please refer to the DEQ 1200-C Plan Checklist for submittal requirements.  For 1200-C Permit Regulations/Requirements, Application Forms, and LUCS Forms, visit DEQ's 1200-C Application page.
