Once a site is under construction, inspections are conducted either once a month or once every two months. The frequency depends on the inspection priority of your project, and will continue until the project is complete or becomes inactive.

Is your site ready for final inspection? To pass final inspection the site requires the following:

• The site is constructed according to the approved plan
• There is a minimum of 70% uniform vegetation
• There are no erosion or sediment control issues
• All synthetic BMPs have been removed (e.g. silt fence, inlet protection)

If you believe your site is ready for final inspection, email Watershed Development staff requesting a final inspection.

A permit can be closed out once the site has passed final inspection and all stipulations listed on the permit have been satisfied. These stipulations may include:

• As-builts
• Infiltration tests
• The submittal of a copy of the Recorded O&M Agreement

If you believe your site is ready for permit closeout, review the Project Close-Out Needs Form and fill out a Escrow Return Request Form.

As-builts are reviewed to ensure the site was constructed according to the approved plan. If you are unsure what items require as-builts, review the handout below.

The time it takes to receive a permit depends on the complexity of the project. View our Applications Under Review section for more details.

If wetlands are present within the site boundary, a wetland delineation will likely be required, especially if you intend to fill, drain or excavate wetlands. If you are still unsure if a wetland delineation would be required, submit a Technical Assistance Form.
