To cover the costs of managing and maintaining stormwater infrastructure, residents and commercial property owners pay an annual stormwater utility fee. This annual fee provides dedicated funding for the City's management of stormwater system infrastructure.
Many property owners formerly paid a stormwater fee as a part of their water bill from the Castle Pines North Metropolitan District (CPNMD). However, when the City began operating and maintaining the public stormwater system in early 2023, CPNMD ceased collection of a stormwater fee. The City began collecting a citywide stormwater fee for the second half of 2023. Moving forward, the fee will be collected on an annual basis.
The stormwater utility fee allows the City to provide an upgraded, consistent service across the entire city. Collecting a stormwater utility fee aligns with other Front Range municipalities and enables the City to ensure proper funding levels to meet stormwater system infrastructure needs moving forward.
Stormwater is rain or snowmelt that falls on streets, parking areas, rooftops, and other developed land and is not absorbed into the ground. As the stormwater flows over driveways, lawns, and sidewalks, it picks up debris, chemicals, and other pollutants. The stormwater either flows directly into nearby bodies of water or travels through the drainage systems to get there. Storm drains are not part of the sewer system, so water in storm drains is not treated before entering streams, rivers, or lakes.
By managing stormwater, communities are better able to protect our environment, reduce flooding, support healthier streams and rivers, and create healthier, more sustainable communities.
The City of Castle Pines is committed to maintaining a proactive stormwater management program to improve the quality of runoff entering the storm drain system and receiving streams. The program plays a critical role in controlling flooding, enhancing safety, protecting the environment, and meeting the requirements of federal environmental regulations.
Castle Pines holds an Environmental Protection Agency Municipal Separate Storm Sewer System (MS4) permit, which requires the City to monitor, maintain and control its stormwater facilities. Stormwater must be managed for the good of the entire community because water runoff does not follow subdivision or community boundaries. The City is responsible for the repair and maintenance of existing stormwater facilities as well as the construction of needed capital improvement projects related to the stormwater system.
