Project Description:

The Queen Creek / Sonoqui Wash Hydraulic Master Plan recommended channelization of Sonoqui Wash.

The third intended phase of channelization includes the main branch of Sonoqui Wash, from Empire Road at Ellsworth Road, northwest to Riggs Road at approximately Hawes Road. This section is located in unincorporated Maricopa County, and the District anticipates funding the project unilaterally. The proposed channel will be designed to collect and convey the 100-year flow, remove 345 acres and 217 homes from the floodplain, and provide protection to roads and other infrastructure.
