Latest News and Updates
The City of Boulder is moving forward with the design of flood mitigation improvements for Gregory Canyon Creek. The city has partnered with The Urban Drainage and Flood Control District, and selected a consultant firm to begin the preliminary design for channel and culvert improvements from Arapahoe Ave. to Pennsylvania Ave.
In order to perform the preliminary design, surveying work will be conducted beginning on April 25, 2019. Residents living along the creek will likely see utility markings in the area as well as surveyors gathering topographic information. We have been reaching out to property owners along the creek corridor to request Right-of Entry for areas where the city does not have easements. Our contractors will only conduct their surveys in areas where the city holds an easement or where the property owner has provided a Right of Entry form. We will also be setting-up meetings with property owners along the creek to discuss design preferences.
