Larimer County has a long history of protecting our natural resources, including stormwater. When dealing with stormwater issues, as a land developer or an individual homeowner, stormwater should be viewed as a valued resource - not a liability. When thought of in this light, it makes sense to protect the quality of that resource from pollution. We remain committed to being good stewards of our water resources. Not because it is required - it's the right thing to do!
In March, 2003, Larimer County adopted a Stormwater Quality Management Plan in compliance with the Phase 2 requirements of the National Pollutant Discharge Elimination System (NPDES) regulation. The goal of the Plan is to protect stormwater quality by controlling and/or eliminating pollutant discharges into stormwater sewer systems.
The regulation requires Larimer County to administer a group of programs to assure water quality is maintained. It also requires any individual or entity, planning construction activities that involve disturbance of one acre or greater, to design and implement erosion control and water quality measures into such activities and obtain a stormwater permit from the Colorado Department of Public Health and Environment (CDPHE).
Following are links to information regarding regulatory requirements as well as general water quality information. They provide useful information for land development issues as well as knowledge of water quality issues.
Stormwater Management Plans Required
Regulations require a permit be obtained from the Colorado Department of Public Health and Environment (CDPHE) for construction activities which disturb an area of 1 acre or larger. (More information)
Larimer County Stormwater Quality Management PlanThe current Larimer County Stormwater Management Plan was approved by the State of Colorado Department of Public Health and Environment (CDPHE). The Stormwater Management Plan describes the County MS4 program within the MS4 Permitted Areas of Larimer County. The permit period was originally approved from March, 2008-March, 2010. CDPHE has administratively extended the current permit term until the subsequent permit becomes effective.
