A change of front elevation or facade shall be deemed to exist when there is a substantial difference in roofline, type and location of windows, and type, kind, color and arrangement of materials. Two (2) or more two-family dwellings of identical or similar front elevations or facades may be located adjacent to one another for design and aesthetic purposes for carrying out a theme of architecture, subject to approval of the Zoning and Planning Commission and the president and board of trustees for the overall plan of the two-family dwellings to be constructed.

Height of top of foundation wall
-
Elevation at highest point on the curb
=
Slope
Distance between back of curb and foundation wall
 
Where there are existing buildings in the block, foundation grades shall be set to equalize the height of all buildings in the block where practicable, unless the existing buildings in the block are set too low in relation to the existing or proposed curb elevation where it then becomes necessary to place a new building foundation grade higher than the existing buildings in the block. Provision shall then be made to protect the lower elevation buildings from the water runoff of the new buildings. Parts of the foundation which are placed at a higher elevation for architectural effect shall not extend for more than forty percent (40%) of the perimeter of the building. However, in all cases, foundation grades must conform to title 6, chapter 14 of this code, flood control and protection.
