RFP No. SW-2020-05 McMurdo Gulch - McMurdo Gulch Stream Reclamation Priority 2 Project

The Town of Castle Rock (Town) is seeking a Consultant Team to provide engineering design and
permitting services for the McMurdo Gulch Stream Reclamation Priority 2 Project. This project
includes design and construction of stream channel improvements to mitigate impacts and preserve the
natural drainageway. The Town completed a McMurdo Gulch Stream Assessment in 2016 that
identified high priority areas for incorporation into the Town’s next phase of stream reclamation. This
Priority 2 Project is located within five specific reaches along the drainageway where early signs of
impact were observed including bank instabilities and head-cutting. The five reaches include:
• Sta. 125+00 to Sta. 132+00
• Sta. 137+00 to Sta. 140+00
• Sta. 152+00 to Sta. 165+00
• Sta. 255+00 to Sta. 260+00, and
• Tributary 5 and 6, Higher Priority.
The Cherry Creek Basin Water Quality Authority is a funding partner with the Town for design and
construction of the project. (see Attachment 1 for Project Site Map).
Expertise for this project is solicited in surveying, geotechnical investigation, alternative analysis,
natural stream drainage design, construction drawings, temporary erosion and sediment control,
hydraulic modeling, technical specifications, construction cost estimation, ecological impacts and
mitigation, environmental permitting, and subsurface utility engineering certification and relocations.
