To provide for development with a low average intensity in areas that include significant important natural features, such as wetlands, creeks, flood-prone lands and steeply sloped areas; to conserve the Swatara Creek; to vary density based upon the natural features of the land; to protect the water quality and habitats along creeks and around lakes and promote groundwater recharge; to provide incentives and a certain amount of flexibility in lot layout through conservation-oriented development so that development can be clustered on the most suitable portions of a tract of land, while avoiding overly intense development.
