Upon application to the Planning Board, extensions totaling a maximum of 12 months may be granted to each of these time periods, for appropriate cause. Such time limits shall be tolled by any judicial proceedings to review the Board's decision.
E. 
Amendments.
(1) 
Minor amendments.

Such minor adjustments shall be consistent with the concepts of the approved site plan.
(2) 
Substantial amendments. Where unforeseen conditions are encountered which require any change to an approved site plan which the Commissioner of Planning considers substantial, or where the applicant wishes to modify the approved site plan for other reasons, an amended site plan shall be filed for review and approval in accordance with the same procedures required for an initial application.

The protection of environmental quality and the preservation and enhancement of property values in the neighboring area. At least the following aspects of the site plan shall be evaluated to determine conformity to this standard:
(1) 
The location, height and materials of walls, fences, hedges and plantings so as to ensure harmony with adjacent development, screen parking facilities and loading spaces, and conceal storage areas, refuse areas, utility installations and other such features. Such walls, fences, hedges and plantings shall, at a minimum, meet the requirements of Chapter 267, Article IV and § 267-44 of this chapter.
(2) 
The prevention of dust, erosion, and drainage onto adjacent properties, both during and after construction, through the planting of ground cover or the installation of other appropriate protective devices and/or ground surfaces.
