Strategic Tree Planting in Sacramento (PDF)
Urban Forests for Clean Air – In 2006, the Sacramento region secured a large Congestion Mitigation and Air Quality Improvement Program grant to support integration of urban forestry in its State Implementation Plan. The project, known as the Urban Forests for Clean Air demonstration project, involves the Sacramento Tree Foundation, the USDA Forest Service, the Sacramento Area Council of Governments and the Sacramento, El Dorado, and Placer and Feather River Air Districts. The project includes three phases: 1) initial estimates of the effects of the urban forest on air quality; 2) development of improved models to analyze these impacts; and 3) a final report on the findings. Under the first phase, the Forest Service's Center for Urban Forest Research estimated the impacts of trees on air quality using existing models and statistical analyses. That analysis predicted that one million additional trees could lower emissions of NOx by almost a quarter ton per day and particulate matter by over one ton per day. If trees that emit low levels of volatile organic compounds (VOCs) were chosen, ground-level ozone could also be reduced by 1.5 tons daily. The long-term goal for the project is to develop the technical support for a SIP revision that includes large-scale, urban tree planting as a ground-level ozone reduction control strategy for the Sacramento region.

Texas San Antonio Tree and Landscape Ordinance Trees and Vegetation San Antonio Ordinance (PDF) San Antonio Tree Preservation Ordinance – San Antonio requires different levels of tree protection based on tree class and 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
