Planting Details and Specifications

Dr. Ed Gilman from University of Florida, Jim Urban, FASLA, and Brian Kempf and Tyson Carroll of the Urban Tree Foundation have developed a modern, up-to-date, and peer reviewed set of details and specifications in AutoCAD, PDF, and Microsoft Word formats for the green industry. These are designed specifically for landscape architects, engineers, architects, contractors, urban foresters, arborists, municipalities, and state agencies.

All these files are open source, free, and can be edited by the user. You and your colleagues are free to use them in projects without charge and without credit to the Urban Tree Foundation or any of the project team members. Although the group encourages modification to fit your specific site and project needs, make your changes only after carefully considering all the pertinent variables at the planting site.

Funding for this project was provided by the California Department of Forestry (CDF), Urban Forestry Program.
