Think of five years worth of Tucson Water’s annual deliveries to 739,000 people.
That’s how much water, totaling about 500,000 acre-feet, that leaders of the three Colorado River Lower Basin states hope to soon find ways to save each year from the river’s dwindling supply, said Bill Hasencamp, a top Southern California water official. Read more...

City of Avondale Low Impact Development Street Tree Master Plan Supplement for Integrating Green Stormwater Infrastructure
The objective of this report is to provide recommendations for how new development can reduce water demands and better utilize urban enhanced runoff to shift towards a water positive future to enable groundwater aquifer stabilization and recovery and support sustained flow in the San Pedro River.
The Sierra Vista sub‐watershed drains to the San Pedro Riparian National Conservation Area (SPRNCA) and the City and region are currently withdrawing more water than is naturally replenished each year. This water deficit can be reduced through a holistic view of stormwater management within the subwatershed. Although this Stormwater Action Plan is specifically focused on the City of Sierra Vista it can serve as a guide for further adoption of Low Impact Development (LID) and green infrastructure practices throughout the Sierra Vista subwatershed.
Watershed Management Group is working with the City of Sierra Vista to “fill the void” in the local water budget and enhance flow in the nearby San Pedro River. Taking what we’ve learned from our experiences working at homes, neighborhoods, and businesses, we applied Low Impact Development (LID) strategies across the Woodcutter Wash sub-watershed in Sierra Vista. Modeling the flow of stormwater produced at each site, and as it flows down to the San Pedro River, revealed that LID features (e.g. rain gardens) produce positive, tangible benefits when adopted on a broad scale.
