6400 South Tributary Stormwater Improvements


Castle Rock Water manages stormwater runoff to minimize flooding hazards, protect the environment and improve water quality. Stormwater improvements are planned to stabilize the 6400 South Tributary drainageway, which flows through Town-owned open space north of Red Hawk Ridge Golf Course. The proposed improvements include a grouted boulder drop structure, riprap and grading within the drainageway channel.

Construction Schedule

Construction is scheduled to begin the week of March 26, 2018 and is anticipated to be completed in approximately six (6) weeks. However, due to Colorado’s unpredictable weather, exact start and end times may vary. Work hours will be 7 a.m. to 6 p.m., Monday through Friday, and 8 a.m. to 5 p.m. on Saturdays. RMC Consultants, Inc. has been contracted to perform the work for this project.


This work is funded by the Town of Castle Rock Stormwater Management Program, and is necessary to protect the drainageway and underground utilities from erosion and preserve this natural resource.
