(2) Sixty percent (60%) of the lot area reduction or not less than ten percent (10%) of the total project area shall be devoted to open space and recreational facilities for the residents of the area being developed. Such open space land or recreatioal facilities shall be held in corporate ownership by the owners of the project area building sites, and the developer shall incorporate into the protective covenants and/or deed restrictions, a clause giving an interest in such land to each owner who buys property within the development.

(4) The lot widths may be reduced not to exceed a ten percent (10%) reduction of the requirements of Chapter 1117.
(5) The lot widths may be varied due to the variety of structural designs and it is recommended that setbacks may be varied. If lot widths for single-family or two-family residential lots are varied by the developer, he shall enter into an agreement with the County that the property owners within a planned unit development of this nature shall be assessed equally for any improvements which may be by assessment, rather than by a front footage basis.

D. That the need for the proposed development has been demonstrated by means of market studies and such other evidence as the Commission may require.
(2) Commercial buildings and establishments shall be planned as groups having common parking areas and common ingress and egress points in order to reduce the number of potential accident locations at intersections with thoroughfares.

Planting screens or fences shall be provided on the sides of the development abutting areas occupied or likely to be occupied by residences.
(3) Off-street parking and loading space shall be provided. Group parking facilities shall provide spaces equal to the number of spaces required for each use to be developed.

All intervening spaces between the street pavement and the right-of-way line, and intervening spaces between buildings, drives, parking areas and improved areas shall be landscaped with trees and plantings and be properly maintained at all times.
