The purpose of the R-1 Residential District is to provide for the orderly expansion of urban-type residential development in areas that can feasibly be supplied with public facilities; to provide for the public health and to prevent the overcrowding of the land through the application of maximum housing densities; to provide standards that will encourage the installation of public facilities, the continuing investment in the Township's traditional neighborhoods, the preservation of public open space and architecturally attractive building facades and landscaping; to provide expanded housing opportunities for seniors; to limit activities of a commercial or industrial nature and any activities not compatible with residential development; to provide for the public convenience and avoid undue congestion on the roads and to otherwise create conditions conducive to carrying out the purpose of this chapter.

A. 
Yards. The yards shall be as required in the chart for permitted uses in an R-1 District. Each yard that abuts a street on a corner lot shall be considered a front yard.
B.

Lot coverage refers to all buildings and structures on the lot including accessory structures, which include patios, walkways, decks, utility sheds, driveways, walkways and all impervious material with the exception of swimming pool basins.

Except for detached, semi-attached and attached single-family dwellings, all uses shall be subject to minimum landscape requirements in addition to lot coverage requirements. A minimum of 25% of the lot area shall be landscaped with grass, trees and shrubbery.
C. 
Building setbacks: The required setbacks for buildings are stated in the chart for § 325-14. The following are exceptions to the setback requirements:
(1) 
A front porch, including any roof gutters, eaves or spouting, may extend eight feet into the required front yard setback in all residential zones, provided:
(a) 
The porch shall not interfere with the sight triangle as defined in Chapter 289, Subdivision and Land Development Ordinance.
(b) 
A minimum of 15 feet shall exist between any porch attached to a nonconforming home and the street right-of-way.
(2) 
Chimneys which are an integral part of the dwelling may extend 18 inches into any yard area.
(3) 
Except for porches as described in Subsection C(1) above, overhangs, eaves, roof gutters and spouting may extend 18 inches into any required yard area.
(4) 
Setback averaging. The building setbacks may be reduced using the average of nearby lots according to the following criteria as interpreted by the Zoning Officer:
(a) 
Front and side building setbacks may be reduced to the average of lots located within 200 feet on the same block and same side of the street as the property in question.
(b) 
Rear yard setbacks may be reduced to the average of lots located within 200 feet on the same block as the property in question.
(c) 
Lots considered in determination of the average setback shall not be located across any private or public street or cartway from the property in question.
(d) 
Lots considered in determination of the average setback shall not be located in a different zoning district than the property in question.
(5) 
Established building lines: The front, side or rear building setback may be reduced for sites with existing nonconforming development in a required setback. The building line of the nonconforming wall serves as the reduced setback line. An addition may increase the building line of a nonconforming setback by up to 50%. However side or rear setbacks may not be reduced to less than three feet in depth; see figure below. This reduced setback applies to new development that is no higher than the existing nonconforming wall. For example, a second story could not be placed up to the reduced setback line if the existing nonconforming wall is only one story high.
