SEMSWA issues three permits for projects in the City of Centennial. They include:
- GESC (Grading, Erosion and Sediment Control) Permit
- SPIP (Stormwater Public Improvement) Permit
- FPDP (Floodplain Development) Permit
After plan approval and original stamped copies are distributed, the Contractor can install initial site BMPs for Grading, Erosion and Sediment Control measures. Once these are installed, the Contractor must call our office at 303-858-8844 to schedule a Pre-Construction meeting with their assigned SEMSWA Inspector. No construction is to begin before permits are issued. Coordination with the City of Centennial Inspector may also be necessary.
Your GESC permit will be issued within 24 hours after the Pre-Construction meeting if all BMPs are found to be in compliance. This permit as well as the SPIP (Stormwater Public Improvement Permit) and FPDP (Floodplain Development Permit) will be issued electronically via email to all parties listed on the permits to include the Owner/Applicant and the Contractor. A copy of each permit must remain on the job site during all phases of construction. This copy may be a printed or digital. Once permits have been issued, construction may begin.
If your project requires multiple permits, they will all be issued simultaneously. There are exceptions for example if your project requires an Early Grading permit or the scope of the work changes requiring additional permitting.
Our permits are issued and expire after 2-years.
