Erosion & Sediment Control
Erosion and sedimentation are natural processes, the intensities of which are increased by land-disturbing activities. Clearing and stripping of land can cause an increase in localized erosion rates, with subsequent deposition of sediments and damage to adjacent, downstream and leeward properties. Erosion can reduce or destroy the aesthetic and practical values of neighboring properties.
The City is committed to the enhancement and protection of existing development, streams, lakes, wetlands and rivers that may be impacted by sediment laden runoff and encourages builders to maintain the natural balance between sediment supply and transport.
It is also the City's policy to encourage water erosion control by leaving land undisturbed as long as possible (by project phasing) and using temporary and permanent erosion control Best Management Practices (BMPs).
Pre-construction: Development and Building Review
Most land-disturbing activities are planned for with Building Services or the Development Review Center; as part of the planning process, all applicable projects are required to submit erosion and sediment control materials (Plan, Report, Escrow) in accordance with the Fort Collins Stormwater Criteria Manual adopted December 2011 with Ordinance 174, 2011 (PDF 4MB). The manual incorporates most of the Urban Drainage and Flood Control District (UDFCD) Manual with amendments that are unique to Fort Collins. The sections of each manual focusing on erosion control and "Construction BMPs" are UDFCD Manual Volume 3 Chapter 7 (PDF 11MB) and Fort Collins Amendment Manual Volume 3 Chapter 7 (PDF 56KB).

An initial inspection is required after acceptance of erosion and sediment control materials and before land disturbing activities can begin. As with all sites across Fort Collins, inspections will then continue until the site is fully stabilized. At that time, final inspections can be conducted and securities can be returned.
To request an inspection, please email ZXJvc2lvbkBmY2dvdi5jb20= with the type of inspection being requested, contact information, building permit number, project name, address and any other relevant information.
