Missouri - Kansas CityTrees and Vegetation; Cool PavementsGreen Parking Lots Case Studies - Green Parking Ordinance (PDF)Green Parking Ordinance - Kansas City, Missouri's proposed parking ordinance contains several innovative planning techniques aimed at reducing the amount of parking and properly filtrating stormwater from parking lots. The ordinance allows for less parking where appropriate and increases shared parking options, especially in downtown areas or along transit stops. The ordinance also sets landscaping requirements for parking lots and provides options for pervious pavements to enhance stormwater management.Active
Oregon - PortlandGreen RoofsChapter 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

Urban Heat Island Project
Dallas Sustainable Skylines Initiative - The Sustainable Skylines initiative is a three-year partnership between the City of Dallas, the U.S. Environmental Protection Agency, and the North Central Texas Council of Governments (NCTOG) to promote sustainability within the City via voluntary programs which emphasize air quality improvements. The initiative has identified the following categories of potential projects to initially perform together: green buildings project, creating a greenhouse gas strategy, green taxis project, off-road equipment replacements and retrofits, renewable energy/energy efficiency outreach program, and an urban heat island project. The goal of the urban heat island project is to develop and implement an urban heat island program for the City of Dallas that will both decrease heated surfaces and increase permeability of surfaces in the Central City and other areas of Dallas.Active
Washington - SeattleGreen Roofs; Trees and VegetationDepartment 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
