A. Street Trees (all streets).
1. Spacing. Street trees shall be spaced equally on individual streets. Spacing should be proportionate to the particular setting. For example, Brunswick Lake Drive will require a wider spacing than a neighborhood street in the Southeast Neighborhood. Landscape plans will be submitted with development plans detailing spacing of street trees.
2. Tree type.
a. In order to attain a coherence and geometry to a streetscape, streets should be planted with one or two different tree types. Individual streets shall not be planted with a variety of species, which creates an incoherent and ill-defined street. Species could vary, however from street to street, to protect against disease, and to avoid the issue of a monoculture. If two different tree types are planted on an individual street, they should be spaced and located in an orderly and rhythmic pattern. The street shall not be divided into two halves with each half of the street planted with a particular tree type.
b. Medium to large trees at maturity should be planted in tree lawns in residential neighborhoods. Small trees such as ornamental trees shall not be used as street trees.
c. Trees shall be planted as close as possible to curbs in order to achieve a canopy affect over the street.
d. Tree grates should not be used due to compression of the root structure. Trees shall be planted in tree lawns or tree pits. Tree pits should be landscaped with ground cover or perennials. Brick or cobblestone paving in sand beds may be used to fill tree pits.
B. Public Spaces. The developer will submit landscaping plans for public spaces to the City for approval. The following general guidelines should be adhered to in the development of landscaped plans for public spaces:
1. Public spaces should be landscaped so as to achieve a coherent and unified environment.
2. Medians and boulevards should follow the same guidelines set forth for street trees. Ornamental trees, however, may be introduced into public spaces. Edges of streets along medians and public spaces should be defined primarily with large tree types.
3. Crosswalks in key public areas, particularly in the Main Street District, should be defined with special paving, or an alternate concrete color.
4. Opportunities for seasonal decoration should be considered in the landscape design of public spaces, particularly in the Main Street District.
5. Opportunities for public art should be identified in landscaped plans of public spaces.
6. A program for placement of seasonal banners and kiosks should be established for the Main Street District.
