Green Evolution provided technical assistance in support of the development of an innovative model water efficiency ordinance for Santa Clara Valley Water District. The model ordinance, developed for adoption by the jurisdictions of the County of Santa Clara in California, includes requirements for residential and nonresidential new developments. The ordinance will help extend the region’s precious potable water supplies, provide a variety of environmental benefits, and protect public health, safety, and welfare.
The model water efficiency ordinance covers the following topics:
The scope of services for the project included:
As the ordinance contained requirements making more restrictive amendments to certain provisions of the California Building Standards Code (Title 24), the ordinance required a detailed cost-effectiveness analysis demonstrating that the relevant standards were cost-effective and required buildings to be designed to consume no more energy than permitted by the California Building Energy Efficiency Standards. The ordinance also required express findings that each amendment to the California Building Standards Code was reasonably necessary because of local climatic, geographical, or topographical conditions. As the ordinance requirements involve both water and energy, this project serves as a tangible example of driving change at the water-energy nexus.
Green Evolution is proud to have supported the development of this innovative and impactful ordinance.
