Flood control efforts continue in the Nogales Wash

August 7, 2017 - 3:52 pm


The recent flows from summer monsoon rains have eroded embankments at a number of locations within Nogales Wash, exposing and threatening critical infrastructure and property. The U.S. Army Corps of Engineers (USACOE) is working to stabilize banks along the Nogales Wash.

The Arizona Department of Transportation delivered 70, 20-foot sections of concrete barrier to assist in the erosion mitigation along the banks of the Nogales Wash.

The Arizona Army National Guard's 253rd Engineering Battalion plans to send nearly two dozen Soldiers and heavy equipment to conduct engineer related training in coordination with the United States Army Corps of Engineers. The Soldiers, who specialize in horizontal construction engineering, plan to train with the USACOE to help mitigate the effects of continuing flood erosion along the Nogales Wash. The 253rd will also conduct training in all-hazards recovery in coordination with local, state and federal partners.

As work continues on the International Outfall Interceptor (IOI) and the Nogales Wash, Santa Cruz County Health Services continues to remind the public to stay out of the Nogales Wash and Santa Cruz River due to health concerns and water quality. Health Officials recommend to those who live within the county, along the Santa Cruz River, and have a private well within 100 ft. of the waterway, have their wells tested for contamination.

With the bypass in place, the untreated wastewater from the IOI is no longer entering the wash. The Arizona Department of Environmental Quality’s sample collection and testing will revert to the normal testing cycle.

The Arizona Department of Agriculture recommends not using water from the Santa Cruz River to water food crops or gardens.

Officials ask that the public and media refrain from entering into areas while repair work is underway. Drivers should be especially careful where crews are working near roadways. As a reminder, the Nogales International Airport has restricted the use of drones within one nautical mile around the crew worksites.

Updates will continue to be posted on the Santa Cruz County Facebook and Twitter @santacruzaz. Public health and safety information is also available at santacruzcountyaz.gov and ein.az.gov.
