Trees; preservation during development.

Preservation of existing trees during development; certain localities. Allows a locality with a population of at least 75 people per square mile or a locality located within the Chesapeake Bay watershed, when assessing the adequacy of existing trees identified by the developer during the development process to be preserved or in assessing the overall impact of the development on existing trees, to require, by ordinance, the developer to (i) submit a survey or map detailing the location of critical root zones on the subject property, including any roots from mature trees that have grown over the subject property line to the abutting property or property adjacent to the subject property, or (ii) provide other information reasonably calculated to assist the locality to determine if such trees are sufficient to meet all or part of the tree canopy requirements.
