[Ord. 871, 5/22/1991, § 118-602]
In reviewing any application, the Planning Commission and Borough Council shall refer the application for development to the Borough Engineer for a recommendation concerning technical compliance with these design standards and the Construction Standards referred to in this Part.
[Ord. 871, 5/22/1991, § 118-603]
1. 
Slope of Land. No land shall be graded, cut or filled so as to create a slope exceeding a vertical rise of one foot for each two feet of horizontal distance between adjoining lots, without proper erosion control approved by the Borough Engineer. Slopes greater than two to one must be approved by the Borough Engineer.
2. 
Stripping of Topsoil. No person shall strip, excavate or otherwise remove topsoil, dirt or slag for sale, or for use other than on the lot from which it is taken, except in connection with the construction or alteration of a building on that lot and the excavation or grading incidental to that construction.
3. 
Major Excavation, Grading and Filling. Any major cuts, excavation, grading, and filling which materially changes the drainage characteristics of the site and the site's relationship with surrounding properties shall not be permitted unless first approved by the Borough Engineer. As a condition for such approval, a plot plan of the entire tract of land on which such excavation, grading and filling are to be conducted shall be submitted by the developer to the Borough Engineer for approval. Such plot plan shall show, in addition to any other information required by the Borough Engineer to demonstrate compliance with the provisions of this section, the following information:
A. 
The existing contours of the site.
B. 
Proposed contours of the site after completion of the excavation, cuts, grading and filling.
The plot plan shall be at a scale of 50 feet to one inch or larger and have a contour interval of not more than five feet where the slope will be greater than 10% and not more than two foot intervals where the slope will be less than 10%. The Borough Engineer shall not approve any plan in which any such excavation, grading and filling will result in a slope exceeding a vertical rise of one foot for each two feet of horizontal distance between adjoining lots or tracts of land, except where adequate provision is made to prevent slides and erosion, as approved by the Borough Engineer.
4. 
Planting and Cutting of Trees; Removal of Debris. Major shade trees should be adequately protected from injury and preserved to the extent practical. All lot areas which slope towards streets or adjacent lots may be required to be seeded with grass or planted with ground cover so as to prevent washing and erosion. During construction, the developer shall remove and dispose of all uprooted trees, stumps, brush, rubbish, unused building materials and debris promptly in the interest of public safety.
5. 
Flood-Prone Areas. Land which is naturally poorly drained or subject to periodic flooding shall not be used for residential development or for any uses which may involve danger to health, safety and general welfare of the community.
