B. Required Common Open Space: A minimum of ten percent (10%) of the gross site area shall be used for permanent common open space, as defined in section 11-2-2 of this title as "open space, common".
C. Quality Of Design:

2. Among the features that may evidence such amenity are:
a. Amount and quality of landscaping;
b. Amount, quality, and interconnectedness of common open space;
c. Provision of pedestrian or bicycle paths separated from streets;
d. Preservation of drainageways and other natural features;
e. Common recreational facilities;
f. Enclosed, underground, depressed, or outstandingly landscaped parking areas;
g. Varied building setbacks or other measures to reduce monotony in design; and
h. Other features as determined by the Planning and Zoning commission.
D. Underground Utilities: All utility lines within a planned unit development are required to be underground. Appurtenances to utility systems that are effectively screened may be permitted aboveground if the village finds that they will not be detrimental to the character of the development.
