1 Article XII R-1 Agricultural-Low Density Residential District Section Declaration of Legislative Intent In expansion of the Declaration of Legislative Intent and Statement of Community Development Objectives found in Sections 101 and 102 of Article I of this ordinance, it is the intent of this article to provide regulations for agricultural and low density residential uses in conformance with the goals of the Comprehensive Plan, Open Space and Environmental Resource Protection Plan, and the following objectives: Establish reasonable standards that permit the continued operation of agricultural uses while allowing limited development of single-family detached dwelling units Direct lower density residential development to areas of the Township that are more rural in character and less likely to be served by the extension of centralized sewer and water system networks Provide minimum lot dimensions which are compatible with the need to provide on-site water supply and sewage disposal Provide standards and criteria for R-1 development in appropriate areas of the township in accordance with the Upper Perkiomen Valley Regional Comprehensive Plan. [Amended 12/09/03; Ord. No ] Section Permitted Uses Agriculture Single-family detached dwelling Institutional uses, in compliance with Article XXVI, Institutional Use Regulations, of this ordinance Open space and outdoor recreational uses, in compliance with Article XXVII, Open Space and Outdoor Recreation Regulations, of this ordinance Non-agricultural uses for agricultural buildings in accordance with Article XXIV Any private utility facility use directly related to and necessary for services within the township, when approved by the Board of Supervisors as a conditional use, subject to the standards and criteria of Section 811, Utilities, of this ordinance Accessory uses in conformance with this Ordinance. 125

The primary purpose of these standards is to preserve the Hosensack Creek Greenway as identified in Figure 12-1 of the Open Space and Environmental Resource Protection Plan (Open Space Plan), and to facilitate acquisition of properties listed as first and second priorities in said plan, while permitting limited levels of subdivision and/or land development that are compatible with those purposes.

9 Section Single Family Development on Institutional Land [Amended 10/11/05; Ord. No ] As a conditional use, a tract of land meeting the requirements of Section that is either an existing institutional use or adjacent to an existing institutional use, that was owned by that institution prior to July of 2005, may be developed or redeveloped with those uses listed in Section Where there are differences in permitted uses and dimensional standards between this section and other sections of this Ordinance, the provisions of this section shall apply Application A. Purposes. The primary purpose of these standards is to provide for the development of existing tracts of institutional land and/or the land adjacent to and owned by institutional uses. As a conditional use, it allows for the development or redevelopment of the tract into single family detached houses, age-qualified detached or attached single family houses, or other uses as listed in Section in accordance with the conditional use procedures in Section 818. In recognition that the institutional use would likely be more intensive than the underlying R-1 Agricultural-Low Density Residential District, a higher density is permitted for the area Qualifying Tract A. Minimum tract size: 50 acres gross. The tract shall include only that land which will be developed as permitted by this Section. Any additional present or previous holdings of the institutional entity shall not be included in the tract size. B. Public sewer and water shall be provided. C.

For the purposes of computing density in a Retirement Complex, two (2) beds in Skilled Care Facilities or Personal Care Congregate Facilities shall be considered the equivalent of one dwelling unit. C. The area that is not used for development shall be set aside as common open space D. Minimum lot area, lot width and yards for single-family non age-qualified detached houses shall be in accordance with Section

10 E. Minimum lot area, lot width and yards for single family detached and attached age-qualified houses shall be in accordance with Sections A. and B, respectively. F.
