Capital Improvement Projects
Yuma County Flood Control District prepares a 5-year Capital Improvement Plan to develop projects to mitigate the drainage and flood control needs identified in the Assessment Report.

The first step taken for capital improvement projects is planning. Master drainage plans for an area or region are prepared to understand all of the needs of an area. The Flood Control District prepares many master plans and area drainage studies. The master plans recommend drainage projects to reduce flooding. These projects are funded by the Capital Improvement Plan. Once funding is available, capital improvement projects are designed and then constructed.

The Flood Control District operates and maintains over 50 drainage facilities throughout Yuma County including retention basins, pump stations, storm drains, outfalls, and groundwater wells.
