Construction begins Monday on a $13 million drainage project to reduce flooding near the Miller Road and Roosevelt Street intersection.

SCOTTSDALE, Ariz. — Drivers and residents near the Tempe-Scottsdale border will see construction for a new major drainage improvement project that begins Monday. It’s a project aimed at reducing dangerous flooding in the area.

The $13 million project, led by the cities of Tempe and Scottsdale, will focus on the intersection of Miller Road and Roosevelt Street, an area officials say has repeatedly suffered from flood damage in past storms.

The new Roosevelt Street Storm Drain will extend an existing 78-inch drain that channels water to the Indian Bend Wash, improving stormwater flow and reducing flood risk. That same wash was the site of a recent fatal incident, when a man was swept away by floodwaters inside his car.

The project will install about 7,500 linear feet of new storm drain, 1,200 feet of lateral connection pipes, and new curb inlet catch basins, manholes, and lateral drains along 74th, 70th and 68th streets.

Funding for the project will come through a partnership between Tempe, Scottsdale, and the Flood Control District of Maricopa County, which will contribute $8.45 million. The two cities will split the remaining costs.

Construction is expected to take more than a year, with completion scheduled for February 2027.
