Pavement is a hard surface that slows down or prevents stormwater from seeping into the soil. Areas considered pavement include:
Paving materials (also known as “impervious surface”) include:
A grading permit is required if you add or replace 2,000 square feet (100 feet by 20 feet) or more of existing paving. If you resurface existing paving you do not need a grading permit. If you remove existing paving and replace it, a grading permit is required once you reach the 2,000 square feet limit.
If you want to pave in or near an environmentally critical area, please come to the Applicant Services Center for coaching.
You may want to hire a professional to help you get your permit. If your project has over 5,000 square feet of new or replaced paving, you are required to hire a civil engineer.
