Tree Database - 2022

This is a Tree Database document maintained by the City of Alpharetta, Georgia, containing detailed inventory and condition assessment data for 1,000+ municipal trees recorded as of 2022. The database catalogs existing trees throughout the city with comprehensive information including species identification, common names, parcel locations, addresses, DBH (diameter at breast height) measurements from multiple years (2003-2022), stem and crown condition ratings, maintenance needs, risk assessments, and appraised values. Trees are classified by location type (street, park, borderline, secondary), overhead utility conflicts, and are assessed for likelihood of failure, potential impact to targets, and overall risk ratings. The inventory serves as the foundation for the city's tree maintenance program and identifies priority candidates for the ongoing pruning and removal services contract that begins December 1, 2022, with potential for four annual renewals under which qualified suppliers furnish labor, equipment, and expertise for tree management operations.

The database reflects the current condition and management status of Alpharetta's urban forest, with tree values ranging from $400 to $60,000 based on species value, location percentage, and appraisal methodology. Assessment data indicates the majority of trees are in fair condition with 60 percent crown health, with primary maintenance needs focused on crown cleaning, removal of vines, and addressing dead and dying parts. Observation notes document specific issues including mistletoe infestation, cavity and decay problems, weakly attached branches, and pest damage affecting numerous specimens. This comprehensive inventory enables the City to prioritize high-risk removals, schedule preventive maintenance, and allocate resources efficiently across its municipal tree stock while supporting the procurement of tree services through competitive bidding processes.
