Density Developments
Density Development is permitted as a Conditional Use in Fox Chapel. That means it must receive special approval from Borough Council. Density Development may be used in the Class “A”, “B” and “C” Residence Districts.

To be eligible for this type of development, a tract of land shall be no less than six (6) acres in area. The total number of single-family dwellings shall not exceed the number permitted under conventional zoning. However, the lot size may be reduced. In a Class “A” Residence District, new lots shall be no less than 1-1/2 acres (65,340 square feet). In the Class “B” Residence District, the minimum lot size is one acre (43,560 square feet) and in the Class “C” Residence District, no lot may be less than 3/4 of an acre (32,670 square feet).

The portions of a Density Development not occupied by single-family lots or roads shall be common open space. The area of common open space shall constitute no less than fifteen (15) percent of the total site. Within the area of common open space, at least fifty (50) percent shall be undisturbed open space. Each parcel of common open space shall be deeded to the Borough, deeded to a private non-profit conservation organization with perpetual existence or held by a homeowners’ association.

Planned Residential Developments
The Borough also permits the use of Planned Residential Developments (PRD) to encourage innovations in residential development, to provide greater opportunities for better housing and recreation, to encourage a more efficient use of land and of public services and also to encourage more flexible land development which will respect and conserve natural resources such as streams, lakes, flood plains, groundwater, wooded areas, steeply-sloped areas and areas of unusual beauty or importance to the natural ecosystem.

A PRD may be located in a Class “A”, “B” or “C” Residence District. The site shall be at least eighteen (18) contiguous acres, all of which shall be located within the boundaries of Fox Chapel.

A PRD may include single-family (“A” and “B” Residence Districts only) or multi-family dwellings such as twin, duplex or fourplex townhouses and apartments. The density of dwellings shall be 0.58 dwellings per acre in a Class “A” District, 0.68 dwellings per acre in a Class “B” District and 1.00 dwellings per acre in a Class “C” District.

At least thirty (30) percent of a PRD tract shall be set aside as undisturbed common open space. This undisturbed common open space shall remain primarily in an area of natural vegetation, to be undisturbed during and following construction.
