How Pima County is tackling flooding issues that come with monsoon storms



TUCSON, Ariz. — It's no secret monsoon storms drench Southern Arizona. Often times, with all that rainfall comes flooding.

Pima County & WMG are tackling flooding issues that come with monsoon storms. If that rainwater isn't kept where it is, and used, it's runoff and lost. 

Pima County is trying to alleviate flooding issues with green infrastructure. It's a way of developing the land that minimizes the impact on the environment. 

A construction site on the northwest side of Tucson may not look like much now, but what's being done there will keep stormwater right where it falls.

The Shannon Garden Project is still in its early stages, but it's part of Pima County's goal of reaching a 20 percent tree canopy. It's the first of 43 green infrastructure projects planned for the county.

Hydrologist Marie Light says this is all to provide more shade, which is something you can't seem to have too much of when it's summer in Arizona. 

"By planting these trees and bushes, we're reducing the temperature in that area," Light said. "Trees can reduce the temperature by 25 degrees."

The sign of a good green infrastructure is one that you don't even know is there, it just works. Everything is strategically laid out -- including the size and location of rocks, trees, and mulch.
