   Development Review   Contact Us
Resources & Documents

The Development Review Section reviews both subdivision and land use cases in unincorporated areas within the District's boundaries. These cases are sent to the District for review by the County Planning Department. The District case reviewers then recommend conditions of approval for these projects to the County Planning Commission and Board of Supervisors. A normal review consists of a flood hazard report and conditions specifically geared to the project for flood protection, facility construction and Area Drainage Plan fees. The District also reviews Water Quality Management Plans for developments in the unincorporated parts of the county including in the Coachella Valley. Development cases within incorporated areas are given only a cursory review that concentrates on District Master Drainage Plan facilities and Area Drainage Plan fees. County Fast Track cases are given priority and the turnaround time for their review is generally less than one week. All other cases are reviewed on a first come, first served basis.
