Pinal County and the City of Apache Junction Approve Creation of Superstition Basin

The city of Apache Junction and the Pinal County Flood Control District have approved the creation of Superstition Basin, a stormwater retention area that will help reduce the impacts of flooding events in downtown Apache Junction.

Under the plan passed by the Pinal County Board of Supervisors on Jan. 3 and the Apache Junction City Council on Dec. 5, 2023, a basin will be built just northeast of the downtown area on land owned by the county just south of the current county complex.

“The city has been working with the county for years to determine the best site for this project to help channel floodwaters from the periodic monsoon storms,” said Jeff Serdy, District 5 supervisor for Pinal County and former mayor of Apache Junction. “I’ve seen what the storms do to homes and businesses downstream, so it is really gratifying to work with the city on this great plan.

The city has continued to address flooding issues from washes that run through the city with stormwater from rains in the mountains northeast of Apache Junction.

“We know how important the downtown area is to our businesses and residents so it was so important to find a solution to regular flooding we see from our summer monsoons,” said Mayor Chip Wilson. “We are working on long-term solutions and this is another step closer to making our city safer and more attractive to new business.”

The location was chosen by the city and the Pinal County Flood Control District based on existing conditions, potential storage volume, and potential future multi-use features. The basin will be constructed in 2024 just east of Idaho Road and south of State Route 88 (North Apache Trail) in an area long designated as open space by the county. 

Under the plan, the basin will hold about 30 acre-feet, or 9,776,000 gallons, of water. It will also have three levels -- a main low-flow and sediment collection area and two levels for overflow storage and potential multi-use amenities for residents and visitors. 

The project is expected to take several months, with the city and county splitting the estimated construction cost of $3.3 million.
