Hillside slopes are both natural and man-made, the latter resulting from cuts for highways, railroads, developments, and mining. The variety of slopes and associated landscape features, such as vegetative cover and streams, define the topographic relief of an area. Each element of relief - slopes, cover and streams - can have different roles in defining a landscape, although they are often tightly associated. The character of the slopes - steepness, elevation, geophysical composition - and local ecological conditions – rainfall, climate - will define the vegetation and hydrology of the landscape. Consequently, one must consider the complete ecological complex associated with hillsides, not just the steepness of its slopes. It is this complex that performs ecological functions and produces valuable services.
Organization: East Vincent Township
Zoning ordinances for East Vincent Township, PA, Chapter 27, which include steep slope ordinances. The township excludes steep slopes, floodplains, and jurisdictional wetlands from its definition of “net tract area,” which is used to establish the maximum number of dwelling units permitted on a tract of land.
Organization: Lower Milford Township
Zoning ordinance for Lower Milford Township, Lehigh County, which include steep slope ordinances. Lower Milford Township takes a more performance-oriented approach to steep slope regulation; within its four-tiered steep slope area, disturbance (i.e. grading, clearing, construction, etc…) is limited to a percentage of the land area occupied by each tier. Use restrictions – in addition to those imposed by the underlying zoning district – only apply to prohibitive slopes.
Organization: City of Pittsburgh
Chapters 905 & 906 of Pittsburgh's zoning ordinances, which contain the city's steep slope ordinances. Pittsburgh's scenic hillsides play a major role in defining its visual character. In addition to a traditional steep slope overlay district, Pittsburgh has both a Hillside District, a base zoning district with unique hillside-appropriate site development standards, and a View Protection Overlay District, which enables the City Planning Commission to create supplemental design guidelines for View Protection Districts, which may include hillsides.
Organization: Delaware Valley Regional Planning Commission (DVRPC)
The Delaware Valley Regional Planning Commission completed a survey of municipal natural resource protection tools in its service area in 2002, which was systematically updated in 2006. Outstanding examples of ordinances related to natural resources, including steep slopes, are posted on this website and are saved as part of this library item.
Organization: Ferguson Township, PA
Ferguson Township's zoning ordinance, which includes steep slope ordinance. The steep slope ordinance has both “Slope Controls” (page 405), and a “Ridge Overlay District (page 64)” designed to limit disturbance to Colluvial soils
Organization: Lehigh Valley Planning Commission
The Lehigh Valley Planning Commission’s model steep slope regulations are primarily use-based in that each slope tier (15 to 25 percent and 25 percent and greater) has a series of permitted, prohibited, and conditional uses. Performance-based standards are embedded in the model ordinance’s “General Provisions” section.
Organization: Commonwealth of Pennsylvania
A major landslide in Kilbuck Township, Beaver County, Pennsylvania, in September of 2006, demonstrates the disastrous consequences of failing to protect the municipality’s steep slopes from disturbance. This report presents the findings and recommendations of the Joint State Government Commission's Task Force on the Kilbuck Township Landslide. which conducted an in-depth investigation into the landslide.
Organization: Wallace, Roberts, and Todd
The Pennsylvania Appalachian Trail Act requires Pennsylvania municipalities along the Appalachian National Scenic Trail to adequately protect it as a public natural resource. Planning and architecture firm Wallace, Roberts, and Todd was hired by a steering committee of municipalities subject to the Act to develop strategies and guidelines for trail corridor protection. This website describes various zoning tools for landscape protection and includes examples of steep slope and ridge regulations.
