What Is a Stormwater Permit?

Stormwater Permit

If you are wanting to do any kind of construction on your property that involves any new buildings or other impervious areas, your local municipality might require a stormwater permit before you can begin construction.

A stormwater permit is documentation that your project has an approved construction plan that includes a stormwater management system. The permit is proof that your proposed project will manage stormwater runoff per municipality requirements.

The Stormwater Management Plan

In addition to the proposed layout of your project, a stormwater management plan should also contain enough information for a site contractor to be able to build the stormwater management system and any associated culverts and storm sewer drains and pipes required to convey runoff into the system. The plan would also contain any applicable construction details.

The stormwater management plan should also have existing and proposed contours to ensure that the site drains as intended during a rainfall event.
