Sites Less Than Five Acres in Specific Jurisdictions: 1200-CN Coverage

    In some local jurisdictions with eligible stormwater programs, construction activities that disturb less than five acres will be automatically covered under the 1200-CN permit. In a few jurisdictions, construction activities that disturb less than one acre are automatically covered. Information needed to determine if your project qualifies for the 1200-CN is available on the Construction Activities web page.

Sites Less Than One Acre: 1200-C Stormwater Discharge Permit Applications

    Fact Sheet: Small Lot 1200-C Permit Coverage
    This explains when a permit is required for construction projects that disturb less than one acre, and outlines how to obtain a permit.

    A 1200-C permit is required for a construction site less than one acre, if it is part of a “common plan of development or sale” disturbing one or more acres. Examples of a large common development or sale include a subdivision, a business park, or industrial park. Individual builders, business owners and home owners must apply for the 1200-C if their construction is within a larger project.

    However, small-lot construction sites within specific local government agencies’ jurisdictions will be managed through local codes and automatically covered under a NPDES 1200-CN Permit, not through the DEQ-administered 1200-C permit. See 1200-CN coverage below to determine if your project is within an eligible jurisdiction.

    The DEQ Small Lot Construction Manual includes a template for the required Erosion and Sediment Control Plan. In almost all cases, this template can be used instead of developing a site-specific plan. A location map and site sketch are used to provide necessary site-specific details. Please see the manual for further details.
