In particular, the City encourages the planting and maintenance of drought tolerant trees and shrubs to create shading, moderate outdoor temperatures, and provide various economic and aesthetic benefits.

All street trees that require removal or pruning to allow for adequate operation of solar collectors shall be removed or pruned at owners expense. All work must be approved by the City and shall meet City specifications. All street tree removals must meet the requirements of § 10-2.06(e).
