The Drainage Division is the largest division in the Public Works Department. Employees in the division are responsible for maintaining 1,600 miles of swale drainage (tertiary system), 158 miles of drainage rights-of-way (secondary system) and 52 miles of waterways and City-owned canals (primary system).
Other duties include installing side lot ditch piping and street culverts, eliminating cross-street paved swales and overseeing a contractor that performs many of the same drainage functions as those performed by employees of the division.
Every year, this division completes approximately 240,000 lineal feet of swale work, installs 100 culverts (thereby eliminating cross-street paved swales), and 20 side-lot ditches.
Roadways are maintained by the Public Works Streets Division. The chief responsibilities of the Streets Division are:
- Street paving
- Pothole repairing
- Street sweeping
- Catch basin cleaning
- Edge of pavement work
The division maintains more than 875 miles of City-owned streets. In 1992, the responsibility for paving and reconstructing our city's road system was also assigned to this division. Since that time, hundreds of miles of roads have received pavement overlays.
Other areas of maintenance responsibilities include street sweeping, applying micro surfacing to curb and gutter areas. The division uses a pavement management system to evaluate street conditions and determine a paving schedule. A five-year road maintenance program has been developed and is updated each year.
A catch basin cleaning program has also been implemented. This drainage system is targeted at those streets with curb and gutter inlets.
Mowing & Landscape Maintenance
The Environmental Services Division is charged with mowing and maintaining all road right-of-way canals within the city, all drainage
rights-of-way and many special areas requiring this type of maintenance.
The 52 miles of canals are the primary system and the 158 miles of drainage right-of-way are the secondary system.
This division also maintains two pump stations that help alleviate
drainage issues and flooding in the City.
