In 2021, ERC worked with the Dry Creek Valley Ditch Company (DCVDC) to revise their Design Criteria Manual. The manual provides guidance for shareholders, developers, and other applicants interested in constructing projects in and around DCVDC facilities. The criteria describe the design review process, fees, and the technical and administrative requirements for obtaining the necessary permits and agreements to complete a project. The manual serves as a how-to guide for those interested in developing adjacent to DCVDC facilities and ensures a high standard of technical design and construction to protect the ditch company and its shareholder. Under the new criteria manual, DCVDC has permitted culvert crossings, ditch relocations/piping, adjacent stormwater detention facilities and other development without impacting ditch operations or maintenance.
