Trees provide cooling through evapotranspiration and shading that decreases temperatures along walkways. Increasing vegetation provides numerous co-benefits like reducing pollution; improving the public realm; and decreasing energy costs. A street tree requirement for new developments or rehabilitations will require private property owners, developers, and businesses to plant trees or provide long-term maintenance for trees in public areas adjacent to their site or property.
Adopt requirements for tree plantings during construction of new or existing developments. This can include requirements for street tree plantings or on-site tree planting.
Considerations for Use
These requirements are most effective when imposed on new developments. Landscaping requirements may not be appropriate in areas with existing dense canopies, poor soil conditions, or limited precipitation. These stakeholders may play a critical role in providing long-term care and maintenance if the tree is in public right-of-way in front of their property
