Boundary definition and mapping.
(a) 
The Steep Slope Conservation District is comprised of areas of steep and very steep slopes, as shown on the Springfield Township Steep Slope Conservation District Map dated June 25, 1985, which is incorporated herein by reference thereto.[2] The map constitutes only a general representation of steep and very steep slopes, based on the analysis of the contours displayed on the United States Geological Survey (USGS) Quadrangle for Lansdowne, Pennsylvania. As such, refined mapping will be required to more accurately define the district, as specified in Subsection B(3)(e) below.
[2]
Editor's Note: The Steep Slope Conservation District Map is on file in the Township offices.
(b) 
Areas of steep slope are characterized by a change in elevation from 15% to 25% over a specified distance or contour interval.
(c) 
Areas of very steep slope are characterized by a change in elevation greater than 25% over a specified distance or contour interval.
(d) 
The Steep Slope Conservation District Map shall be considered as an overlay to the Springfield Township Zoning Map,[3] subject to the following:
[1] 
The district shall have no effect on the permitted uses in the underlying zoning district, except where said uses, intended to be located within the boundaries of the district, are in conflict with the permitted uses set forth in Subsection C.
[2] 
In those areas of the Township where the district applies, the requirements of the district shall supersede the requirements of the underlying zoning district(s).
[3] 
Should the district boundaries be revised as a result of judicial decision, the zoning requirements applicable to the area in question shall revert to the requirements of the underlying zoning district(s) without consideration of this section.
[3]
Editor's Note: The Zoning Map is on file in the Township offices.
(e) 
Interpretation of district boundaries.
[1] 
The applicant shall use an actual field topographic survey as the source of contour information and the basis for depicting steep and very steep slopes as described below.
[2] 
The Steep Slope Conservation District Map, based on the ten-foot contour interval from the United States Geological Survey, shall be used as a general guide for determining the boundaries of the district. In any application for subdivision and/or land development, the applicant shall, using two-foot contours as required in Chapter 123, Subdivision and Land Development, delineate slopes from 15% to 25% and greater than 25%. However, for the purposes of this section, such slopes shall be delineated on the basis of three consecutive contour intervals or a six-foot cumulative vertical change in grade.
[3] 
Once delineated, the mapping of the applicant will be reviewed by the Township Engineer. The applicant will be required to follow all regulations of this section for those areas which reflect steep slope and very steep slope conditions as determined through the Township Engineer's review.
