Watershed Plan and Environmental Assessment

Posted By Administration, Monday, August 31, 2020

The County of Graham Arizona is requesting letters of interest to prepare a Watershed Plan and Environmental Assessment for the Gila Valley Flood Protection and Watershed Improvement Project.

Firms with experience preparing Watershed Plans and Environmental Assessments for USDA-NRCS in the arid west are encourage to submit letters of interest to Graham County Board of Supervisors 921 Thatcher Blvd, Safford, Arizona 85546 or email dwelker@graham.az.gov.

The purpose of the Graham County Flood Protection and Watershed Improvement

Project is to enact flood mitigation measures, update drainage structures, update structures for Agriculture Water Management, and complete practices to manage storm water runoff and subsequently reduce erosion and sedimentation issues. Population growth in the rural area has shifted drainage patterns.  Current infrastructure has either become inadequate or new infrastructure is needed. Irrigation canals which run through municipalities have become part of the drainage system.  Canal infrastructure is antiquated, and the canals do not have adequate capacity to handle storm water runoff. In addition, recent wildfires in the mountains above the watershed have increased the potential for harmful flood events
