The New Street Tree Manual is here!

A new resource is available—a Street Tree Manual providing a one-stop tree care reference for residents, developers, contractors and tree service providers. Click this link to open the PDF, or contact us to see a printed copy.

The manual puts into a descriptive form the requirements and standards established by the Street Tree Ordinance—which was updated in 2013 for the first time in 50 years.
