1043.055 PROTECTED WATERSHED REQUIREMENTS
(a) For any regulated activity within a protected watershed (high quality or exceptional value), the applicant shall meet requirements as contained in 25 PA Code, Chapter 93 as required and applicable.
(b) Existing Resources and Site Analysis Plan. Shall be prepared for all regulated activities other than construction of a single family residence (and ancillary structures) to provide the developer and the Municipality with a comprehensive analysis of existing conditions, both on the proposed development site and within 500 feet of the site. Conditions beyond the parcel boundaries may be described on the basis of existing published data available from governmental agencies and from aerial photographs. The Municipality shall review the plan to assess its accuracy, conformance with Municipal ordinances, and likely impact upon the natural and cultural resources on the property. The following information shall be required.
(b)(1) Complete current perimeter boundary survey of the property to be subdivided or developed prepared by a registered surveyor, showing all courses, distances, and area and tie-ins to all adjacent intersections.
(b)(2) Natural features, including:
(b)(2)(A) Contour lines at intervals of not more than two feet. (Ten-foot intervals are permissible beyond the parcel boundaries, interpolated from USGS published maps.) Contour lines shall be based on information derived from a topographic survey for the property, evidence of which shall be submitted, including the date and source of the contours. Datum to which contour elevations refer and references to known, established benchmarks and elevations shall be included on the plan.
(b)(2)(B) Steep slopes in the following ranges: 15% to 25%, 25% and greater. The location of these slopes shall be graphically depicted by category on the plan. Slope shall be measured over three or more two-foot contour intervals.
(b)(2)(C) Areas within the floodway, flood fringe, and approximated floodplain.
(b)(2)(D) Watercourses, either continuous or intermittent and named or unnamed, and lakes, ponds, or other water features as depicted on the USGS Quadrangle Map, most current edition.
(b)(2)(E) Wetlands and wetland margins.
(b)(2)(F) Riparian buffers.
(b)(2)(G) Soil types and their boundaries, as mapped by the USDA Natural Resource Conservation Service, including a table listing the soil characteristics pertaining to suitability for construction and, in un-sewered areas, for septic suitability. Alluvial and hydric soils shall specifically be depicted on the plan.
(b)(2)(H) Existing vegetation, denoted by type, including woodlands, hedgerows, tree masses, tree lines, individual freestanding trees over six inches DBH, wetland vegetation, pasture or croplands, orchards, permanent grass land, old fields, and any other notable vegetative features on the site. Vegetative types shall be described by plant community, relative age, and condition.
(b)(3) Existing man-made features, including:
(b)(3)(A) Location, dimensions, and use of existing buildings and driveways.
(b)(3)(B) Location, names, widths, center line courses, paving widths, identification numbers, and rights-of-way, of existing streets and alleys.
(b)(3)(C) Location of trails that have been in public use (pedestrian, equestrian, bicycle, and the like).
(b)(3)(D) Location and size of existing sanitary sewage facilities.
(b)(3)(E) Location and size of drainage facilities.
(b)(3)(F) Location of water supply facilities, including wellhead protection areas.
(b)(3)(G) Any easements, deed restrictions, rights-of-way, or any other encumbrances upon the land, including location, size, and ownership.
(b)(3)(H) Site features or conditions such as hazardous waste, dumps, underground tanks, active and abandoned wells, quarries, landfills, sand mounds, and artificial land conditions.
(b)(4) Total acreage of the tract, the adjusted tract area, where applicable, and the constrained land area with detailed supporting calculations.
(c) Consultation Meeting (Optional). Prior to any stormwater management permit application submission, the land owner or developer shall meet with the Municipality for a consultation meeting on a concept plan for the post-development stormwater management system to be utilized in the proposed project. This consultation meeting shall take place at the time of the preliminary plan or other early step in the development process. The purpose of this meeting is to discuss the post-development stormwater management measures necessary for the proposed project, as well as to discuss and assess constraints, opportunities, and potential ideas for stormwater management designs before the formal site design engineering is commenced.
(d) All proposed regulated activities within a protected watershed shall utilize, to the maximum extent possible, low impact development practices as contained in Appendix B to Ord. 509-11.
