Climate Action for Health (PDF)
Integrating Public Health into Climate Action Planning - The California Department of Public Health has developed a guide to how health and climate change are related. The guide identifies strategies to reduce the urban heat island effect, a consequence of climate change. The strategies include developing well-vegetated urban parks, exploring the role of landscaping and green roofs, planting urban forests, and using light-colored building and pavement materials.Active
California - StatewideUrban Forestry Program; Demonstration ProjectCalifornia Urban and Community ForestryCalifornia Urban Forestry Program - This program is the lead for the development of sustainable urban and community forests in California. It provides information, education, and assistance to local governments, non-profits, private companies, and the general public that help to advance urban forestry initiatives. Through the program, the state plants an average of 10,000 to 20,000 trees a year. Local governments and non-profits can apply for grants from the program; eligible projects include non-traditional urban forestry initiatives such as green roofs. In Fiscal Year 2009/2010, the program funded a green roof project in San Diego.Active
District of Columbia - WashingtonDemonstration ProjectCourt 5 Green RoofUSDA South Building Court 5 Green Roof - This 3,500 square foot green roof followed the installation of a 500 gallon cistern that catches runoff from an adjacent roof and provides irrigation for the new green roof. The green roof reduces the urban heat island effect, is more aesthetically pleasing than conventional roofs, and manages stormwater runoff that is entering local waterways and the Chesapeake Bay.Completed
District of Columbia - WashingtonIncentiveGreen RoofsDC's Unified Green Roof Rebate Program - The program provides base funding of $5 per square foot for a green roof, with a cap of 5,000 square feet. Additional funding can be provided for features that add to environmental goals. Green roofs offer numerous benefits, including reduction of the heat island effect and improved stormwater management. The program is administered by the Anacostia Watershed Society for the District Department of the Environment (DDOE). It helped the DDOE develop a Green Roof Toolkit that assists District building owners with making decisions on designing and installing green roofs.Active
Georgia - AtlantaDemonstration ProjectFrances Bunzl Administration Center Green RoofFrances Bunzl Administration Center Green Roof - The green roof on top of the High Museum of Art’s Frances Bunzl Administration Center was completed in April, 2008. It will help to mitigate the urban heat island effect, reduce energy consumption, and improve air quality in downtown Atlanta. The roof was financed partially through a Nonpoint Source Implementation Grant from U.S. EPA, which is awarded to projects that address non-point source pollution through strategies such as stormwater management. This modular green roof will be able to retain about 70% of total rainfall, or 62,000 gallons of stormwater per year. The project also allowed the Savannah College of Art and Design to take part in the plant selection and to film a documentary on the module installation.Completed
Illinois - ChicagoDemonstration Project; ProcurementGreen Alleys


Green Alleys Handbook (PDF)
Chicago Green Alleys - Chicago, after the success of a demonstration project using permeable pavement, began a Green Alley initiative to use permeable pavement any time it needs to re-pave an alley. Through 2009, more than 100 Green Alleys have been installed and ultimately, almost 2,000 miles of alleyways will be made permeable. The Green Alley Handbook notes that "if all the alleys had a light, reflective surface (high albedo) that reflected heat energy, [they would stay] cool on hot days and thereby reducing the "urban heat island effect." The handbook also mentions the heat island reduction benefits of shade trees and green roofs.Active
Illinois - ChicagoDemonstration ProjectCity Hall Rooftop GardenChicago's City Hall - The City of Chicago installed a green roof on its city hall that includes 20,000 plants, shrubs, grasses, vines, and trees. This 20,300 square foot roof is about 100 degrees cooler than nearby roofs. The city has saved about $5,000 in energy costs annually, and savings may increase as energy prices fluctuate. In addition to assessing energy impacts, the green roof has been designed to test different types of rooftop garden systems, success rates of native and non-native vegetation, and reductions in stormwater runoff. This city hall green roof has helped to raise the visibility and increase public understanding of green roofs. Chicago's Department of Environment staff has frequently given presentations about the roof, which has won numerous awards.Completed

Oregon - PortlandZoning Code; Building CodeChapter 33.510 (PDF)Central City Plan District Zoning Code - In 2001, Portland, Oregon modified its zoning code to include an "eco-roof development bonus" for developers to install green roofs (which are called "eco-roofs" in the code). In Title 33 of the Zoning Code there is a floor area ratio bonus for projects that install green roofs in Portland's central district. The bonus amount depends on the extent of the green roof coverage. If the green roof covers 60% or more of the roof surface, developers can build an additional 3 square feet (0.3 m2) for each square foot of green roof. If the green roof covers a lower percent of the surface, the bonus is reduced.Active

Washington - SeattleZoning CodeDepartment of Planning and Development - Green FactorSeattle Green Factor - Seattle has adopted minimum landscape requirements, known as the Seattle Green Factor, for new developments in commercial areas in the city. This program requires that, as of late January 2007, certain new developments in neighborhood business districts must provide for vegetative cover on the equivalent of 30% of the applicable property. The regulations apply to developments with more than four dwelling units, more than 4,000 square feet (370 m2) of commercial uses, or more than 20 new parking spaces. Developers can use a menu of strategies, including planting new trees, preserving trees, and installing green roofs and green walls to meet this target. The regulations are part of the city's Commercial Code and encourage planting of layers of vegetation and larger trees in areas visible to the public. The rules also include bonuses for harvesting rain water and choosing plants that need less water. The city has developed a worksheet to help applicants calculate a "score" that indicates whether various mixes of landscaping measures meet the requirements, which will allow developers to try different combinations of features.Active
