(a) Purpose. This district is established to protect and preserve the most rural areas of the City in which agriculture, woodlands, wetlands, other sensitive environmental areas, and low-density residential development are the predominant land use patterns. Overall existing residential density is less than one dwelling unit per five acres, consisting primarily of single-family detached estate homes. There remain large amounts of open space and potential development areas. The regulations contained in this district will permit continued, low-density residential development, but will encourage new residential development that incorporates rural residential conservation designs and other open space preservation techniques, in order to preserve the existing rural character and limit development in sensitive environmental areas such as wetlands, floodplains, or aquifer recharge areas. Other permitted uses include agriculture, park and recreational uses, institutional uses, and public uses.

A. Open space conservation subdivisions encouraged.
1. All residential developments or subdivisions of five or more lots that satisfy the minimum five-acre parcel size threshold set forth in Section 1207.06(d) are encouraged to utilize the open space conservation subdivision provisions in order to preserve a substantial amount of land for open space use and, to the maximum extent feasible, to prevent development in environmentally sensitive areas including but not limited to woodlands, wetlands, and wellhead protection/aquifer recharge areas.

B. Lots abutting railroad right-of-way: In order to enable an increase in the rear yard setback and allow room for a landscaped buffer between the dwelling and the railroad right-of-way when a lot abuts and backs onto a railroad right-of-way, the minimum lot width may be reduced by not more than ten percent provided the lot depth is at least 250 feet.
A. Open space conservation subdivisions: All residential open space conservation subdivisions shall comply with the setback and yard requirements set forth in Section 1207.06(e).
B. All other developments–case-by-case determination: Because of the pervasiveness of environmentally sensitive areas within District 2, building setbacks and yard requirements for development shall be determined on a case-by-case basis by the PC either during the subdivision approval process or during the site plan approval process. All determinations of setbacks and yard requirements shall use as a starting point the minimum setbacks set forth in divisions (d)(5)C. through E. of this section, which may be modified pursuant to the conditions and criteria set forth in Section 1207.01, Maximum Impervious Surface Coverage.
