Special District Service Plans, 1978-2012
Series 191 (28 Boxes)
Approved service plans of special districts in Jefferson County. A special district is a political subdivision of the state established to provide a public service (such as water, sanitation or fire protection) within a specific geographic area.
Because Colorado law limits the types of services that county governments can provide, special districts are created to fill the gaps in the services counties provide and those its residents desire. The majority of districts draw their boundaries in unincorporated county land, but residents of a municipality may be included in one or more districts.
When a special district is created, they are required to submit a service plan that outlines the services they will provide. The service plan also provides a financial plan for the procurement of land and facilities that may be necessary to provide the services. Service plans must be submitted to the Board of County Commissioners for approval. After board approval and a successful election creating the district, the service plan, along with a certified court order organizing the district is filed with the county Clerk and Recorder and the state’s Division of Local Government.
