C.

The PD District can only be applied to a site of at least four (4) contiguous gross acres in size.

D.

The PD District shall be individually designed to meet the needs of the territory so zoned. It shall be adopted by a zoning ordinance which incorporates by reference a general development plan for the entirety of the subject property. The general development plan shall include drawings and text as specified in Section 10.05.047. Development of the subject property can hereafter occur only pursuant to an effective PD permit issued in strict conformity with the adopted general development plan or alternatively, in accordance with the requirements for the base district if one exists.

E.

Under no circumstances shall the City ever be required to approve a PD Zoning District. The discretion to grant or deny such permit is unrestricted and nothing contained in this Title shall be deemed or construed to limit the discretion in any way whatsoever. Unless and until a PD permit has been issued and becomes effective, the subject territory may be used only as if it were situated in the base district alone.

The minimum lot size "L" shall be determined by the following formula where S is the percent slope of the site as defined in the Monte Sereno Subdivision Chapter and expressed as a whole number:

L = 43,560 square feet
5.45 -.089 S

The application shall be in the form prescribed by City and accompanied with the payment of the required application fee.

3.

Hearing Process: Use Permits shall be considered in accordance with the requirements of Chapter 10 of this Title. If the Use Permit for clustering is related to any other application including Site Development permit and/or subdivision map, the City Council shall exercise final approval authority over all related applications.

4.

All cluster developments shall meet the requirements of the Subdivision Chapter pertaining to engineering, health and safety, dedications, ecology, maps and documents.
