These criteria are intended to insure that homes integrate well with each other and share designs which make neighborhood streets safe and enjoyable to walk along. Lot sizes and patterns within a neighborhood must be varied to avoid monotonous streetscapes and provide a diverse range of housing types. For example, larger building types on larger lots are encouraged on corners. Smaller lots are encouraged surrounding common open spaces. The table on the following page summarizes lot sizes and approximate densities for a variety of housing types.
Densities apply to gross developable acreage.
Gross developable acreage is the total buildable area within a parcel, including local streets, but excluding public open space, neighborhood parks, schools, and environmental constraints. Private on-site open space may further reduce the density of a particular development. Each model of a particular type may have the same lot size but should have varying floor plans and varied exterior treatments and materials. Each development of 100 or more homes must have at least four models with three elevations and material treatments each. For developments of less than 100 units, at least three models with three variations each are required.
