Title
Resolution Approving a Third Amendment to the Amended and Restated Intergovernmental Agreement Between the Town of Castle Rock and Douglas County for the Highway 85 Wastewater Collection and Treatment System [Located along the Highway 85 Corridor North of E. Happy Canyon Rd. to W. Titan Rd. in northern Douglas County]
Body

Executive Summary
Castle Rock Water (CRW) staff recommends Town Council approval of a Resolution (Attachment A) approving a third amendment (Exhibit 1) to the previously approved Amended and Restated Intergovernmental Agreement (IGA) with Douglas County. The proposed third amendment will include a contribution from Douglas County to provide up to $300,000 for design services for sanitary sewer main infrastructure in Sedalia. The County and the Town have partnered in the project to construct a sanitary sewer lift station and force main to Plum Creek Water Reclamation Authority. The County is investing over $14 million in American Rescue Plan Act funding, and the Town of Castle Rock is providing over $5 million in upfront funding to be recovered in system development fees. The IGA outlines that the Town will manage the project, and own and operate the sewer infrastructure once completed.
The sewer lift station and force main are the basis for centralized wastewater service in the area. However, funding is currently unavailable to construct the gravity sewer mains needed to transition existing residents, businesses, and facilities from septic systems to centralized wastewater service. These improvements are also essential to support future economic growth and development that will require centralized wastewater infrastructure. An initial phase for sewer main infrastructure has been identified that would run from the north side of Highway 85 through the Town of Sedalia to the lift station that will serve as the backbone for full buildout of sewer mains in Sedalia. CRW and Douglas County will partner on this first phase of sewer main infrastructure that can be later built out to connect more services in future phases. The initial phase would provide opportunity to connect a future planned Douglas County public works facility as well as CORE electric. The proposed amendment will allow CRW and Douglas County to partner on starting the design of the sewer main infrastructure.
Budget Impact
The funding provided by Douglas County will be added to CRW’s current budget for the Highway 85 Wastewater Collection and Treatment System to cover the cost of the design services.
