Stormwater Improvements Along East Plum Creek

Stormwater improvements, funded by Castle Rock Water, are underway along East Plum Creek (EPC). The work is located within the Town-owned open space southeast of Brookside Circle (across from Medved). This area along EPC has been impacted by storm flows within the channel. Improvements include grade control and bank stabilization, and are required to protect the Town’s water supply system in this area. There will be limited, if any, inconvenience to trails and roads.

These improvements are needed to address a severely eroded stream bank immediately adjacent to one of the Town’s well heads and minimize risk of stream degradation over the newly constructed alluvial well horizontal lateral arms.

These existing wells are a critical component of the Town’s renewable water supply system needed to maintain peak summer water demands. Constructing stormwater improvements that maintain a healthy stream system are an integral part of preserving long-term water supplies for our residents.   

Construction schedule


Construction began in March 2017 and is expected to be substantially complete in August 2017. However, due to Colorado's weather, the exact start and completion dates may vary. Generally, construction hours will be from 7 a.m. to 5 p.m. Monday through Friday and 8 a.m. to 5 p.m. on Saturday.

Additional re-vegetation is scheduled to be completed in spring 2018.


Although there will be temporary impacts to the stream during construction, this project will provide a net benefit to natural habitat that benefits wildlife, water quality and the Town’s natural resources.
