Drainage Group
The Drainage Group is primarily responsible for the crossroad culverts and pipes, roadside ditches, concrete curbs and sidewalks, bridges, detention ponds and drainage channels. It is comprised of a superintendent, three foremen and 38 maintenance workers who make up three drainage crews, each consisting of specialized teams. Each team has a primary function, but can assist or supplement the other teams.
- Crossroad Pipe Maintenance Team – This team focuses its efforts on culverts and pipes that are at right angles to the road centerline. Repairs and maintenance of these structures includes reinforcement of worn materials, and keeping the inflows and outflows in a safe, good, working condition. Normally, when these structures are replaced, excavation with heavy equipment is required.
- Longitudinal Ditch Maintenance Team – This team focuses its efforts on the ditches and pipes that run alongside the roadway. They repair washouts from severe rain storms, and keep the ditches properly shaped and free of debris, plants and other materials that may inhibit the correct flow of storm water.
- Right-of-Way Maintenance Team – This team focuses its efforts on all other structures in the right-of-way that require maintenance and repair.
- Concrete Maintenance Team – This team is responsible for repairing concrete sidewalks, curbs, gutters and the concrete headwalls and abutments on various drainage structures.
- Service Request Response Team – This team focuses on cleaning pipes and structures that have become partially filled or completely clogged with sediment, plant material, or refuse carried in the storm water.
- Bridge Maintenance Team – This team repairs and maintains the bridges in the county. Their work includes replacing headwalls and abutments that support the bridges, joists and stringers that support the deck, along with the deck and railings. They also repair or replace guardrails.
- Detention Ponds and Drainage Channel Team – This team concentrates on keeping the retaining dams in good repair along with spillways and channels required to keep storm water properly stored, detained or flowing.
