Overview of Urban Forestry Development Review
Urban Forestry is responsible for reviewing street, city, and heritage trees. Urban Forestry reviews are conducted any time a project is valued at $25,000 or greater and any time a street, city, or heritage tree may be impacted or removed by the development. For more details, visit the simplified overview we created that outlines the entire process.
Tree Plan Requirements
Tree plans must be included in a development permit application. Our Tree Plan Requirements for Development Permits page outlines what you need to know to meet plan requirements.
As part of the tree plan requirements, you will need to know about on-site tree preservation and on-site tree density requirements. You can learn more about when tree preservation and density requirements apply, exemptions, and other information by visiting our On-site Tree Preservation page and our On-site Tree Density Requirements page.
