(See also Article
IX for land developments.) Preliminary plans shall be prepared by a qualified professional (see definition in Article
II), as applicable, and required by state law. The submission requirements for a preliminary plan shall consist of the following elements and shall be prepared in accordance with the drafting standards and plan requirements described herein:
- Site context map.
- Existing resources and site analysis.
- Preliminary resource impact and conservation analysis.
- Preliminary improvements plan.
- Preliminary studies and reports as set forth in other parts of this chapter.
A. Drafting standards.
(1) The plan shall be clearly and legibly drawn at a scale of one inch equals 10 feet, 20 feet, 30 feet, 40 feet, 50 feet or 60 feet.
(2) Dimensions shall be in feet and hundredths of feet; bearings shall be in degrees, minutes, and seconds for the boundary of the entire tract; and dimensions in feet for lot lines.
(3) The surveyor shall certify on the plan that the map or plat, and the survey on which it is based, were made in accord with current accepted Pennsylvania practice, and include the date on which the field work was completed.
(4) The sheet size shall be no larger than 30 inches by 42 inches but 24 inches by 36 inches is preferred. If the plan is prepared in two or more sections, a key map showing the location of the sections shall be placed on each sheet. If more than one sheet is necessary, each sheet shall be the same size and numbered to show the relationship to the total number of sheets in the plan (e.g., sheet 1 of 5), and a key diagram showing the relative location of the several sections shall be drawn on each sheet.
(5) Plans shall be legible in every detail.
B. Site context map. A map showing the location of the proposed subdivision/land development within its neighborhood context shall be submitted. For sites under 100 acres in area, such maps shall be at a scale not less than one inch equals 200 feet and shall show the relationship of the subject property to natural and man-made features existing within 1,000 feet of the site. For sites of 100 acres or more, the scale shall be one inch equals 400 feet and shall show the above relationships within 2,000 feet of the site. The features that shall be shown on site context maps include topography (from U.S.G.S. maps), stream valleys, wetland complexes (from maps published by the U.S. Fish & Wildlife Service or the U.S.D.A. Natural Resources Conservation Service), woodlands over 0.5 acre in area (from aerial photographs), ridge lines, public roads and trails, utility easements and rights of way, public land, and land protected under conservation easements.
C. Existing resources and site analysis. For all subdivisions and land developments, an existing resources and site analysis plan shall be prepared to provide the developer and the Borough with a comprehensive analysis of existing conditions, both on the proposed development site and within 200 feet of the site. Conditions beyond the parcel boundaries may be described based on existing published data available from governmental agencies and from aerial photographs. The Borough shall review the plan to assess its accuracy, conformance with Borough ordinances, and likely impact upon the natural and cultural resources on the property. The following information shall be required:
(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.
(2) Natural features, including:
(a) Contour lines at intervals of not more than two feet. In the case of flatter areas, one-foot contours may be required (10-foot intervals are permissible beyond the parcel boundaries, interpolated from U.S.G.S. 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. The datum to which contour elevations refer and references to known, established benchmarks and elevations shall be included on the plan.
(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.

(d) Wetlands as defined by Article
II.
(e) One hundred-year floodplains, including delineation of floodway and flood fringe, established by study of FEMA, with base flood elevations for the 100-year storm.

Alluvial and hydric soils shall specifically be depicted on the plan.
(g) Existing vegetation, denoted by type, including woodlands, hedgerows, and specimen vegetation, as defined in this chapter, tree masses, tree lines, wetland vegetation, pasture or crop lands, orchards, permanent grass land, old fields, and any other notable vegetative features on the site.
(h) Any portion of the tract identified as a Pennsylvania Natural Diversity Inventory (PNDI) site. If such habitats exist on the tract, the measures proposed to protect the habitats shall be indicated.
(i) Ridgelines and watershed boundaries.
(j) Geologic formations on the tract, including rock outcroppings, cliffs, sinkholes, and fault lines, based on available published information or more detailed data obtained by the applicant.
(3) Existing man-made features, and including:
(a) Any easements, deed restrictions, rights-of-way, or any other encumbrances upon the land, including location, size, and ownership.
(b) Locations of Historic and Archaeological Resources which have been identified and/or inventoried by the Borough, the County, the Carbon County Planning Commission, and/or the Pennsylvania Historical and Museum Commission and all significant sites or strictures on the tract, including, but not limited to foundations, cellar holes, stone walls, earthworks, and burial sites.
(4) The gross tract area, total tract area, adjusted tract area, where applicable, and the constrained land area with detailed supporting calculations.

390-28C). All proposed improvements including, but not necessarily limited to, grading, fill, streets, buildings, utilities, and stormwater detention facilities, as proposed in the other preliminary plan documents, shall be considered in preparing the resource impact and conservation analysis, which shall clearly demonstrate that the applicant has minimized site disturbance to the greatest extent practicable.
(2) Using the existing resources and site analysis as a base map, impact areas shall be mapped according to the following categories:
(a) primary impact areas (i.e., areas directly impacted by the proposed subdivision/land development);
(b) secondary impact areas (i.e., areas in proximity to primary areas which may be impacted); and,
(c) designated protected areas, either to be included in a proposed conservation open space or an equivalent designation such as dedication of a neighborhood park site.
E. Improvements plan. This plan shall include the following items:
