Step one: zone change designation. The first step is a change of existing zoning to planned development (PD) district designation. In considering a zone change, the Village Board options include approval of the change, approval with binding stipulations (ordered by the Village Board) or denial. The Village Board may request a recommendation and comments from the Planning Board prior to consideration. Any zone change to a PD district must be based on a specific development proposal. The request for PD zone district designation must include a land use, utility and circulation plan developed to concept stage. Primary vehicular and pedestrian routes and linkages must be shown. Adequate sources of water, sewer, electric, gas and other utilities must be shown and/or identified. Specific requirements may be established during the zone change designation portion of the PD district review process with respect to such development details as minimum lot sizes within the district, lot coverage, building height, yard dimensions, off-street parking, transportation facilities, stormwater management, and density of residential use. For projects being developed in phases, the plans submitted for this step must address all phases. Evaluation of these details is made, so far as is practicable, within the overall scheme of a PD district. PD districts may be proposed for any area(s) within the Village. Land uses in a PD district should be compatible with the general zoning categories of adjacent land established in this chapter. A PD district is not intended to accomplish spot zoning. The minimum project size to be considered for PD district is five acres.
