California - Chula VistaCool Roofs; Trees and Vegetation; Cool PavementsClimate Change Working Group – Climate Action PlanningBuilding Code; Demonstration Project; Green Building Program and Standards; Tree and Landscape Ordinance - The City of Chula Vista has identified 11 climate adaptation strategies, three of which directly address urban heat islands: they include the installation of cooler paving products, cooler roofing materials, and the incorporation of more shade trees. The city is sponsoring a demonstration project that will evaluate multiple reflective pavement technologies and develop implementation options based on these results. It is also working to amend its green building standards code to require cool roofs on all new residential developments, as well as developing a policy to require all municipal improvement projects and private parking lot development projects to incorporate a certain percentage of shade trees based on the development size.Active
California - DavisTrees and VegetationChapter 37 of the City of Davis Municipal CodeDavis Landscaping Ordinance - The City of Davis requires that 50% of the paved parking lot surface of any building shall be shaded with tree canopies within 15 years of acquisition of a building permit. Specific guidelines for the development of such canopy are outlined by the city. Only trees from the city's list may be used as parking lot shade trees unless otherwise approved by the city's arborist. It is recommended that the genera of trees be varied throughout the parking lot. Trees shall receive 25%, 50%, 75% or 100% shading credit based on their location relative to paved surfaces.Active
California - MartinezCool Roofs; Trees and VegetationThe City of Martinez Climate Action PlanMartinez Climate Action Plan - Martinez Climate Action Plan – The City of Martinez is addressing the issue of urban heat islands in its climate action plan. The city aims to reduce the heat island effect through targeted upgrades of existing buildings and paved areas; adoption of new building standards, including the new cool roof standard contained in California’s Title 24 Energy Standards; tree planting; and new requirements for shading in new parking lots and other large paved areas.Active
California - SacramentoTrees and VegetationSection 17.68.040 Tree Shading Requirements for Parking LotsSacramento Parking Lot Shading Ordinance - Since 1983, an ordinance in Sacramento's zoning code has required that enough trees be planted to shade 50% of new, or significantly altered, parking lots after 15 years of tree growth. A 2001 study found that the lots were only achieving about 25% shading because sometimes shade was double-counted, trees did not grow to their expected size under conditions of the lot, or trees were not adequately dispersed. Based on these findings, Sacramento modified its code in 2003 to improve coverage.Active

Florida - Miami-Dade CountyTrees and VegetationSee Chapter 18AMiami-Dade Landscaping Ordinance - In 1995, Miami-Dade County established landscaping ordinances for different classes of structures, which establish requirements for planted vegetation surrounding all buildings.

Florida - Miami-Dade CountyTrees and VegetationMillion TREES MiamiMillion TREES Miami (MTM) - MTM is a communitywide effort to plant one million trees by 2020. Miami-Dade County created the Street Tree Master Plan as a framework to design and implement street tree planting. This complements the city’s landscape and tree ordinances and will help reach the goal of 30% tree canopy cover in the city by 2020. The program will help mitigate the urban heat island effect in Miami and reduce the city’s energy consumption. Other co-benefits include reduced stormwater runoff and improved air quality.Active

Illinois - ChicagoTrees and VegetationLandscape OrdinanceChicago Landscape Ordinance - Chicago has a landscape ordinance that requires planting trees or shrubs on parkways and landscaping parking lots, loading docks, and other vehicular use areas, both within the sites themselves and to screen their perimeter. The ordinance applies to most new building construction, as well as repairs, remodeling, and enlargements of a particular size and cost. The Bureau of Forestry, which maintains the standards, must inspect and approve all parkway vegetation prior to planting. The Chicago Department of Zoning reviews all building and zoning permit applications to ensure compliance with the ordinance.Active

Louisiana - Baton RougeTrees and VegetationChapter 18 Landscape and Trees (PDF)Baton Rouge Landscape and Trees Ordinance - In 2007, the City of Baton Rouge strengthened its landscape ordinance, which requires tree planting on all new developments, excluding single-family residences. The ordinance requires two shade trees for every 5,000 square feet of site, and one shade tree per 600 square feet of street frontage. Parking lot requirements include one shade tree per 15 parking spaces for a lot with one to 25 spaces; one shade tree per 12 parking spaces for a lot with 25 to 100 spaces; and one shade tree per 10 parking spaces for a lot over 100 spaces. For example, a 10,000-square-foot site with 600 square feet of storefront and 150 parking spaces would require 20 shade trees (i.e., four for the square footage of the site, one for the store frontage, and 15 for the parking lot).Active
Maryland - AnnapolisTrees and VegetationSee Chapter 17.14Annapolis Energy Efficiency Resolution - In October 2006, Annapolis, Maryland adopted a comprehensive energy efficiency resolution that included general goals and specific long-term targets for adopting a range of energy efficiency measures. One recommendation was to increase tree shading so that the city could sequester carbon dioxide, reduce the urban heat island effect, and lower ozone levels. In 2007, the city adopted a new tree protection ordinance as one step to protecting existing shade trees. This resolution also proposed green building goals, including adopting green building standards for public buildings, investigating incentives for green building construction, and developing an outreach and education program for the building community and government staff. The resolution also proposes increasing the urban forest canopy to 50% of the city’s land area by 2036.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
Texas - San AntonioTrees and VegetationSan Antonio Ordinance (PDF)San Antonio Tree Preservation Ordinance - San Antonio, Texas requires different levels of tree protection based on tree class or location. The ordinance classifies significant trees, heritage trees, and trees within the 100-year floodplain. For example, heritage trees (defined, for most species, as trees 24 inches [60 cm] or greater in diameter at breast height), must be preserved. The ordinance, however, generally counts total tree diameter-inches at a site, not individual trees, and gives flexibility in preservation: up to 90% of the tree-diameter-inches can be considered preserved if the developer plants an equal or greater number of tree-diameter-inches elsewhere. Developers can also fulfill the preservation requirement by contributing to the city's tree fund.Active
