Planning and Zoning for Solar Energy
Do your community's plans and ordinances address solar energy systems? As the nation's centers of electricity consumption, cities and counties are uniquely positioned to support economic growth, strengthen America's energy independence, and reduce pollution by converting to solar energy. Planners have important roles to play in making sure their communities' plans and land use regulations allow and encourage this clean, safe energy source.
This Essential Info Packet, updated for 2014, provides an extensive collection of sample ordinances on topics such as solar access, solar siting, and solar energy systems large and small, along with many examples of how communities are adding solar provisions to their comprehensive, subarea, and functional plans.
This packet is being made available to all planners and the general public as part of APA's participation in the SunShot Solar Outreach Partnership (SolarOPs), an initiative of the U.S. Department of Energy (DOE). Through this effort, APA and its partners are providing outreach, training, and technical assistance to local and regional governments to make it easier for residents, businesses, and property owners within their jurisdictions to use solar energy. Find the latest SolarOPs resources and keep up-to-date on upcoming and previous SolarOPs workshops, webinars, and technical assistance opportunities at http://solaroutreach.org.
