Report
Summary
In early 2014, FCDMC partnered with the City of Phoenix to conduct a study that finalized the Hohokam Area Drainage Master Plan Level 3, which resulted in the Recommended Plan Report. Later, in 2015, they began work on a study to update the Laveen Area Drainage Master Plan for the South Phoenix/Laveen area, using new mapping and comprehensive flood modeling software. This update was informed by the Laveen Area Drainage Feasibility Study conducted by the City in early 2022. These studies included an analysis of existing regional drainage improvements, such as detention basins, channels, and storm drains, and concluded with recommendations for Flood Hazard Mitigation Projects.
The FCDMC Capital Improvement program (CIP) provides an opportunity for cities to cost-share flood hazard mitigation projects through local drainage solutions, emphasizing projects that mitigate historical flooding issues. The program provides cost-share opportunities for project-related design and construction costs.
In February 2024, staff submitted a CIP application to the FCDMC for the GO Bond Flood Hazard Mitigation Projects in coordination with community members and drainage evaluations.
The following projects have been grouped into three packages based on location and connectivity. FCDMC has requested separate IGAs for each package's design and construction phases. Under the cost-sharing arrangement, the City's share is estimated to be 35 percent of the project cost after FCDMC's financial assistance of 65 percent.
