Density calculation. The applicant shall submit a sketch plan for a conventional subdivision conforming to the minimum lot size, requirements and standards otherwise applicable to the district or districts in which the subdivision is located in order to establish the number of dwelling units permitted in a conservation subdivision. Said sketch plan must show that each lot meets the minimum lot size and area requirements for the zoning district in which it is located and that each lot shown can be developed as a viable single-family residential lot. Except as specified herein, all development standards and controls normally applicable to conventional subdivisions shall also be applicable to conservation subdivisions. Thus, areas of land needed for roads and infrastructure as well as site constraints that limit the number of lots in a conventional subdivision shall be taken into account in determining the number of lots allowable in a Conservation Subdivision. The area of lands which may be required for parks, playgrounds or recreation areas in a Conservation Subdivision, if any, or a fee in lieu of such parks, playground or recreation areas, shall in no case exceed the area of such lands that may be required in a conventional subdivision. However, the area of lands which would be required in a conventional subdivision for parks, playgrounds or recreation lands pursuant to the Town's Subdivision Regulations shall be excluded in determining the number of lots permitted in a Conservation Subdivision.
