This 20-foot front yard area may be developed with a combination of landscape and hardscape elements, such as plazas, fountains, benches, and tables. Additional shade tree plantings are encouraged within public gathering places and alongside pedestrian paths . Buildings shall have varying setbacks to create the informal crossroads community setting. b.

For each 80 feet of building exterior wall , the bu i lding exterior and roof shall be offset by a minimum of ten feet. Overhangs and roof lines shall follow the building 's locat ion. b. For each 80 feet of building exterior wall , there shall be a change in details, or patterns or materials . (6) Parking . a. Parking shall be shared among users within a common development. Parking shall be reduced according to the shared parking standards established i n section 64-1411 . Additional reduction in the number of parking spaces is encouraged. b.

In addition, buildings should reflect a specific style and not mix elements of different styles . The design and architectural elements of the build ings should be compatible to those of the area . In Milton, commercial buildings are built at the intersect ions of two major roads in a pattern of rural development called "crossroads commun ities ." Residences are constructed at the edge of these crossroads commun ities . The overlay district seeks to rep li cate this pattern by having future nonresidential construction , built w ithin 400 feet from the edge of the r ight-of-way of an intersection, include elements of the historic commercial buildings, and nonresidential bu ildings, constructed over 400 feet from the edge of right-of-way of an intersection, include elements of the historic resident ial bu i ldings .

Exaggerated or excessively large or small architectural elements should be avoided. Elements should be in proportion with the overall building. In addition, buildings should reflect a specific style and not mix elements of different styles . The design and architectural elements of the buildings should be compatible to those of the area . In Milton, commerc ial buildings are built at the i ntersections of two major roads in a pattern of rural development called "cr ossroads communities ." Res idences are constructed at the edge of these crossroads communities . The overlay district seeks to replicate this pattern by having future nonresidential construction, built within 400 feet from the edge of the right-of-way of an intersection, include elements of the historic commercial buildings, and nonresidential bu i ldings, constructed over 400 feet from the edge of right-of-way of an intersection, include elements of the historic residential buildings.
