Project Overview: 

The Town of Oro Valley stormwater utility department has been experiencing maintenance and repair issues throughout the town’s drainage infrastructure. The Town determined the need to update the drainage criteria manual to account for the unique desert hydrologic conditions such as flash floods and sediment transport. The Town relied up on the experience of Riley’s senior engineers who have extensive experience in southwest desert hydrology & hydraulics and geomorphology to improve upon the current manual by incorporating engineering methods and practices specific to the region.
