Zoning (or development control regulation) is a tool that can be used to enact ordinances used to define and delineate development and land-use. (O’Brien et al, 2017; Miller, Hauer, & Werner, 2015)
Cities may use zoning to create, expand, or maintain urban forests. For example, zoning may provide a mechanism to:
Mandate the amount of open space in a city, leaving room for trees to grow
Designate protected or sensitive areas such as riparian buffer strips or steep slopes
Regulate patterns of development in a way that leaves room for urban forests
Provide tree planting requirements for new projects
