Maricopa County Sustainable Development Incentive Program

The purpose of this program is to create incentives for sustainable development including to increase energy and water efficiency in existing and new developments; increase resource conservation; and promote sustainable development practices. Sustainable development features that qualify for incentives include:

1. Using roofing material with a solar reflectance index (SRI) equal to or greater to the following:
• Low sloped roof – less than or equal to 2:12 – SRI value of 78
• Steep slope roof – greater than 2:12 – SRI value of 29
2. Site hardscape heat island reduction: Not less than 50 percent of site hardscape is (a) hardscape materials with an initial solar reflectance value of not less than 0.30; (b) combination of shade structures and shaded by trees; or (c) pervious paving, open-grid pavers.
3. Site development incorporates functional rainwater harvesting that irrigates at least 20 percent of the total landscape area. Development installs alternative on-site rain water runoff systems that incorporate rainwater harvesting features, pervious paving, and other similar systems.
4. Any other innovative sustainable design feature(s) found to meet the intent of this chapter, to be reviewed and accepted at the discretion of the zoning administrator.
4. Site development incorporates roof top solar panels, with a minimum size of 2.5 kwh for each panel.
