Greetings Todd:
Since urban and community forestry is not my area of expertise, I recommend contacting Tom Dilley with the USDA Forest Service, Urban Forestry, out of Evanston, IL. Tom should be able to steer you in the right direction.

Sorry I couldn't be of more help, but my forestry expertise is more traditional forest management and silviculture.
