Drainage Division
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.
