The City of Arvada oversees construction sites within their jurisdiction to minimize the potential for pollutants to leave the site, including sediment. A Site Development Permit is issued to owners, developers, contractors, or builders who must install and maintain adequate best management practices (BMPs) to control pollutants.
Do I Need a Site Development Permit?
All projects that disturb 10,000 square feet or more of land must obtain an Arvada Site Development Permit. Complete the Site Development Permit Application and provide the required documentation for review.
Those projects that disturb an acre or more (or less than one acre if part of a larger common plan of development) must also obtain a State Stormwater Discharges Associated With Construction Activity General Permit, the webpage for which can be found under "Important Links" to the right. The requirements of the State and City permits are similar.
Site Development Plan Process
Sediment and erosion control plans that show how pollutants will be controlled must be submitted for review and approval and include the standard Plan Notes (see Requirements). Standard Details for every BMP in the plan must be included and can be either Arvada's BMP Details (see Requirements) or Details found in the Urban Drainage and Flood Control Drainage Criteria Manual, Volume 3 (see Important Links).
A narrative Stormwater Management Plan must be developed and submitted for review when a project is one acre or more. The complexity of the plans submitted should be in accordance with the complexity of the proposed project. Please note:
- Approved sediment and erosion control plans must be followed, and updated as the site is developed.
- Disturbed earth is limited to 60 acres on any one site.
An individual lot, if that lot is part of a larger common development, must obtain a Site Development Permit. If the lot is less than 10,000 square feet in area, a Permit will be awarded at no cost. The Small Site Brochure can help identify typical BMPs needed.
Fees for the Site Development Permit vary from $50 to a maximum of $125. A cash escrow or letter of credit of $2,000 plus $200 per acre must be on file with the City.
