The purpose of these requirements is to enhance, conserve, and stabilize property values by encouraging pleasant and attractive surroundings and to provide proper separations between uses. Landscaping is required for the purpose of minimizing stormwater runoff and diversion, preventing soil erosion and promoting the aesthetic character of the community. Landscaping also contributes to the reduction of heat and glare through the proper placement of plants and trees.

Areas which have been cleared of vegetation or groundcover prior to or during construction, and which are not otherwise developed, shall be landscaped with trees, shrubs and suitable groundcover. Suitable materials for groundcover are those which permit rainwater infiltration of the soil and may include sod, ivy, bark, noncompacted gravel and the like.
J. 
Landscaping Islands and Peninsulas. To the greatest extent practicable, landscaped areas shall be dispersed throughout the impervious surface area. Truck parking and loading spaces are exempt from this requirement.
