As an integral part of the Town of Castle Rock's vision of providing its residents with the highest quality services at the best value, the Stormwater Division manages stormwater runoff to minimize flooding hazards and to protect water quality in our watersheds. Services the Stormwater Division provides include:
The Stormwater Division is funded through monthly services charges based on an urbanized footprint calculated for each account. New housing / commercial development is charged a development impact fee to account for downstream system improvements. This fee covers the cost of operation, upgrades, maintenance and improvements to the Town’s storm drainage facilities.
In accordance with Castle Rock Municipal Code, Chapter 13.30, Article 13.30.60, non-single family properties are entitled to appeal for an adjustment to the stormwater utility fee.

These projects preserve, enhance and, in some cases, reconstruct the natural floodplains in our community. This infrastructure serves to reduce public risk from stream channel erosion and flooding. These projects also have a water quality component that ensures our renewable drinking water supplies are preserved and protected.

Storm sewer improvements
Storm sewer projects capture and contain runoff to reduce flood risk. These projects are in established street rights of way and are typically aligned with the Public Works street maintenance and repair program. These conveyance systems are independent of wastewater sewer systems and lead directly to the creek.
