BACKGROUND
City of Brighton was approved last fall for a grant from the Colorado Department of Transportation Water Quality Mitigation Funding Pool in an amount of $421,978. To design and construct a stormwater quality pond at Veterans’ Park. The pond will treat stormwater runoff prior to discharge to the South Platte River. Through the conditions of a previously approved IGA, Colorado Department of Transportation will reimburse the City up to four hundred twenty-one thousand nine hundred seventy-eight dollars ($421,978) to design and construct the stormwater quality pond.
Stormwater runoff from an approximately 90-acre basin currently discharges to the McCann Ditch and, ultimately, the South Platte River untreated at two locations near Veterans’ Park: One location on the south side of Highway 7 and the other on the north side of the highway. This drainage basin encompasses portions of multi-family residential development, Downtown Brighton and the intersection of Highways 85 and 7.
The project is to construct a stormwater quality pond on the north side of Highway 7 and will re-direct flows from the south side of Highway 7 north to the stormwater quality pond. This will allow treatment of the entire 90-acre basin.
Colorado Department of Transportation is required by its stormwater drainage permit to provide funding to local governments to assist the Department in treating the stormwater runoff from their highway system.
A large amount of trash, debris and sediment from this basin discharges to the McCann Ditch and South Platte River after storm events. The stormwater quality pond is designed to capture this trash debris and sediment and prevent pollution of waterways. The collected pollutant sources are then removed from the pond through regular maintenance activities.
Additionally, the project will be completed concurrently with the installation of a missing link in the Colorado Front Range Trail through Veterans’ Park. The City of Brighton received a grant from Adams County Open Space to build the trail. These projects are to be completed by one design-build team, under separate contracts. The two contracts will have separate grant funding sources.
It is anticipated that education signage will be included along the trail to educate the public about the importance of stormwater runoff quality and the function of the stormwater quality pond. The signage will be funded through the Stormwater and Environmental Division public education operating budget account.
