The guide is intended to provide you an overview of the permitting process for storm sewer work.
Storm sewer work includes the following:
Before you start your project, you need to know what regulations apply to your property and what factors may impact your project. You'll need to consider:
Any project that encroaches on a designated parkway setback will need to undergo parkways review. Certain parkways and boulevards are specifically designated by ordinance to preserve their unique character. Each designated parkway has its own right-of-way width and regulations of setback distance of structures and signs. If you are unsure if you live along a designated parkway or for your parkway’s specific regulations, enter your address into the DevelopDENVER tool at right. Look under “Designated Parkways” on the results panel on the left. If a specific parkway appears, click on the “Details” button for information on setbacks.
If any portion of your project has the potential to affect the trunk, canopy or roots of the street trees around your property, before you begin, you must contact Denver Forestry by email (firstname.lastname@example.org) or phone (720-913-0651) to evaluate your project. Any removal, trimming or planting of trees within the public right of way must be permitted through the City Forester’s Office. Damages to street trees may result in the issuance of administrative citations and/or fines. Visit the Denver Forestry web page and click on Property Owner Resources for information on hiring a licensed tree service company or requesting a permit.
Location of Existing Sewer Lines
If you plan to build a new structure over or within 2 feet of the existing sanitary sewer, you will need to replace the sanitary sewer with approved materials. A plumbing contractor can help you locate the sewer lines on your property. Visit Wastewater Sewer Use and Drainage Permit (SUDP) for application, guidelines and other specific information. Contact the Department of Public Works at 303-446-3759 for additional details.
Transportation review and approval is needed if you are changing the location of any driveways that connect to public streets or proposing improvements, such as changing the curb cut, within the “right of way” (ROW), which includes public streets and sidewalks. All ROW projects must be performed by a licensed contractor and in full compliance with the City Charter, ordinances, permitting processes and all other applicable standards, specifications and requirements. Licensed contractors can obtain ROW permits at Public Works Permit Operations, 2000 West 3rd Avenue, or directly from the ROW inspector at (303) 446-3469. NOTE: Alterations to a driveway that connects to an alley, instead of a public street or sidewalk, do not require transportation review.
Listed in the order they must be obtained. All permits must be in hand and at site before work may begin.
The above must be in hand before you apply for the following:
SUDP application and materials may be submitted by email (email@example.com), online at via e-Plan or in person at the Development Services Permit Counter. Sign in online once for SUDP permit (SUDP).
For Wastewater, there is a $100 application fee plus appropriate fees. There are no fees for Parkways review. ROW permit fees are based on the amount of work constructed and the amount of time they are occupying the ROW. View the permit fee schedules to estimate other fees required for your project.
