Planned developments, as defined in chapter 2 of this title, are of such substantially different character from other special uses that specific and additional standards and exceptions are hereby set out to govern the recommendations of the planning and zoning commission and approval of the board of adjustment and appeals.
A. Use Exceptions: In the case of residential, business or manufacturing planned developments, the planning and zoning commission may authorize that there be in part of the area of such development and for the duration of such development, specified uses not permitted by the use regulations of the district in which said development is located, provided the commission shall find:
1. That the uses permitted by such exception are necessary or desirable and are appropriate with respect to the primary purpose of the development;
2. That the uses permitted by such exception are not of such a nature or so located as to exercise a detrimental influence on the surrounding neighborhood;
3. That not more than twenty percent (20%) of the ground area of such development shall be devoted to the uses permitted by said exception; and
4. That in an industrial planned development, such additional uses allowed by exception shall conform with the performance standards of the district in which the development is located, as set forth in this title.
B. Bulk Regulations: In the case of any planned development, the commission may recommend and the board of adjustment and appeals may authorize exceptions to the applicable bulk regulations of this title within the boundaries of such development, provided that the commission shall find:
1. That such exception shall be solely for the purpose of promoting an integrated site plan no less beneficial to the residents or occupants of such development as well as of neighboring properties than would obtain under the bulk regulations of this title for buildings developed on separate zoning lots;
2. That the minimum lot area per dwelling unit requirement of this title shall be adhered to in any such development containing residential uses, and that there shall be available to each residential building and immediately adjacent thereto (including the land area upon which it is erected) the minimum amount of land area required for such buildings under the lot area per dwelling unit provisions of this title;
3. That spacing between principal buildings shall be at least equivalent to such spacing as would be required between buildings similarly developed under the terms of this title on separate zoning lots, due consideration being given to the openness normally afforded by intervening streets and alleys; and
4. That along the periphery of such planned developments, yards shall be provided as required by the regulations of the district in which such development is located. (Ord. B-39, 1969)
