Should your local government prioritize investing in green infrastructure for flood and water management?
Recent monsoon storms in Tucson have filled the 121-acre Kino Environmental Restoration Project basin to capacity. The site collects stormwater runoff from a 17-mile watershed to protect downstream areas from flooding.
Why it matters
The basin serves as a critical flood control structure while also conserving groundwater. By harvesting stormwater, the project reduces reliance on local water supplies and lowers operational costs for the neighboring sports complex.
The basin captures runoff from a 17-mile watershed and includes a 50-foot-deep pond. It provides necessary irrigation for 34 fields at the adjacent Kino Sports Complex.
The players
Pima County Regional Flood Control District
This agency manages flood risks and infrastructure projects throughout the Pima County region.
U.S. Army Corps of Engineers
This federal agency provides engineering services and infrastructure development for public water projects.
The details
Constructed in 2001 by the Pima County Regional Flood Control District and the U.S. Army Corps of Engineers, the facility utilizes specialized flood control structures to manage water. Beyond its utility, the area has become a habitat for as many as 250 bird species.
Timeline
The Kino Environmental Restoration Project was built in 2001.
Monsoon storms filled the basin to capacity in October 2026.
The Sonoran Desert Conservation Plan celebrates its 25th anniversary in 2026.
The Mosaic Quarter Iceplex is scheduled to open in the spring of 2027.
Seasonal Patterns
The project serves as a practical implementation of the goals outlined in the Sonoran Desert Conservation Plan. It demonstrates how historical water management strategies are increasingly integrated into broader regional ecological conservation efforts.
Residents should remain aware of potential standing water near the Kino Sports Complex as the basin manages overflow. The facility continues to support irrigation needs for local recreational fields and will eventually supply water to the upcoming Mosaic Quarter Iceplex.
The takeaway
The basin highlights the effectiveness of using flood control infrastructure to sustain local amenities and wildlife habitats. Residents can expect continued water conservation benefits as the facility prepares to support new developments like the ice complex next year.
