Promote the preservation of land and waterways which because of location or natural features have a unique character for open space and recreation purposes, and to facilitate and provide for the conservation of significant natural resources.

Permit and encourage the retention of existing and potential open space and recreation areas, significant natural resources, water bodies, and lands in and around the major water features such as the Upper Perkiomen Valley Park and the Unami and Macoby Creek corridors, which constitute a unique and important natural resource of the Township.

Ensure the retention of large expanses of woodlands and forest preserves that conserve other important resources; moderate the effects of winds and storms; absorb pollutants and noise; serve as a shelter for wildlife; and provide a diverse environment for the Township.

Preserve aquifers and maintain both the quantity and quality of groundwater.

Maintain rural and scenic vistas, especially onto, from, and around water bodies, and ridge or hilltops.

Ensure that access to such open space, recreation, and conservation lands is not blocked by private development and that is encouraged through appropriate legal mechanisms.

Establish reasonable standards of performance in order to maintain the desirable benefits of open space, recreation, and conservation areas.

Ensure that the uses in this district will not have any adverse effect on the natural amenities and resources located here or in abutting residential areas.

Relate open space, recreation, and conservation areas to existing residential areas and to existing or potential "open space" type areas on adjacent tracts to assure consistency of use and lack of conflict between adjacent areas.
