Stantec, Autocase, and Watershed Management Group (WMG) were engaged by the City of Phoenix (City) – with The Nature Conservancy (TNC) as a contributing and reviewing partner – to perform a triple bottom line cost benefit analysis (TBL-CBA) of various Green Infrastructure/Low Impact Development (GI/LID) features, as well as look at the triple bottom line impacts of three case study sites in the area.
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.
This manual provides information for neighborhood residents, municipal professionals, grassroots advocates and others who seek to implement green infrastructure (GI) strategies in their communities. It offers a neighborhood-centered perspective on GI that is tailored to work with the unique climate conditions of the southwestern US.
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.

Rainwater on Tap: Drinking Local, By The Numbers
WMG’s Living Lab and Learning Center is quickly on its way to being a rainwater-fed campus—and letting the municipal water lines go dry. Utilizing 3,200 square feet of roof space across two buildings, we are collecting the abundant water that falls from the sky. Ten thousand gallons of this bounty is stored in an underground tank, with another 2,000 gallons held in above-ground cisterns.
