§ 27A-507. Street Trees.

(a)

General

(1)

Approved tree species for use in an Urban Center District shall be selected from the Landscape Manual. The manual includes native and acceptable adapted species.

Invasive exotic species shall not be used anywhere on private lots or other areas within an UC District.

(2)

Trees shall be placed as shown in Section 27A-503, or as specified in the Regulating Plan for placement along the Street Tree Alignment Line.

(b)

Intent

(1)

Street Trees are part of an overall Street-Space plan designed to provide both canopy and shade and to give special character and coherence to each Street-Space. The desired aesthetic shall be achieved through the use of native and/or proven hardy adapted species. The Street Tree lists of species in the Landscape Manual may be amended over time. Street Trees serve several crucial functions in the construction of the Street-Space:

(A)

Structural - Street Trees shape and subdivide the Street-Space, increasing pedestrian comfort and adding value to the Street/community. Species appropriate for canopy shade trees typically grow to heights in excess of sixty (60) feet and have a broad canopy-enabling them to clear auto traffic and pedestrians, form a ceiling-like enclosure, and open a clear view of the Street-Space and shop fronts at eye-level.

(B)

Pragmatic - Life as a typically placed Street Tree is typically short. Few species are tough enough to survive to an appropriate height. Appropriate species have special tolerance to salt and soil compaction. Street Tree planting techniques and configurations provide a healthy environment in which the tree can thrive-this shall ensure that the trees increase the community value as they grow.

(C)

Design - Species are planted consistently along a given Street-Space to provide a special form and character to each Street. Provide species diversity at the same time you provide diverse Street character by planting different Streets with different trees.
