Maintenance

The Maintenance Work Plan is developed for each county and for the South Platte River based on a prioritized list of drainageway maintenance requests from each local government in that county where the drainageway is the responsibility of the local government. Maintenance work is divided into two types of activities, routine and restoration. These activities are described in greater detail below

Routine maintenance consists of limited mowing of native vegetation, trash and debris cleanup, trash rack cleaning, control of weeds and noxious vegetation, tree thinning, sediment removal, revegetation, and other minor drainageway maintenance activities. Private contractors are hired each year to perform the routine maintenance activities on a unit price basis.

Restoration work involves site specific construction activities intended to rebuild and reestablish existing drainage facilities which have been neglected or damaged such that structural problems have developed. Examples include reconstructing or replacing grade control structures, box culverts, retaining walls; establishing or repair of maintenance access; local channel grading, stabilization, and revegetation. Private contractors are hired to provide these services through a public selection process.
