City of Chamblee UDO Addendum 2.0 Buffer, Landscaping, and Tree Preservation Administrative Guidelines May 19, 2015
On October 20, 1998, the City of Chamblee unanimously passed a Tree Preservation Ordinance, which was most recently revised in 2014 and combined with the City s zoning buffer and landscaping ordinances within one ordinance (Chapter 320 of the Unified Development Ordinance). This ordinance provides standards for the preservation and/or replacement of the City of Chamblee s trees and requirements for zoning buffers and landscape areas. What follows are the administrative guidelines to be considered during the permitting process in coordination with Chapter 320 requirements. These guidelines have been approved by the City Landscape Coordinator and by the Chamblee City Council. Any questions about these guidelines or about the permitting process should be directed to the City of Chamblee Development Department.. Table of Contents 2.1.
