Land shall not be developed or changed by grading, excavation or the removal or destruction of natural topsoil, trees or other vegetative cover unless adequate provisions for minimizing erosion and sedimentation are provided.
(A) A plan for erosion and sediment control shall be prepared and submitted to the borough. The plan shall meet all requirements and be approved by the County Conservation District, the borough and the State Department of Environmental Protection (Chapter 102 of Title 25, latest revision), when applicable.
(B) (1) The erosion and sediment control plan shall be submitted at final plan submission.
(2) The plan shall contain two parts:
(a) A map(s) describing the topography of the area within the subdivision or development, the proposed alterations of the area, and the erosion and sediment control measures and facilities which are proposed; and
(b) A narrative report describing the project and giving the purpose, engineering assumptions, and calculations for control measures and facilities.
(3) The map(s) shall show:
(a) The types, depth, slope and area extent of the soils on the site;
(b) The proposed alteration to the area, including:
1. Arrows indicating existing and proposed runoff flow direction, when contours do not adequately describe flow paths;
2. Areas of cuts and fills exceeding five feet in vertical difference;
3. Structures, roads, paved areas, buildings;
4. Stormwater and erosion and sediment control facilities; and
5. Existing contours on the site at intervals required by this chapter and finished contours at the same interval. The Borough Council may require that the proposed grading of individual lots be shown on the plan.
(4) The following certification statements:
(a) “I CERTIFY THAT THE PLAN OF DEVELOPMENT AND THE PLAN FOR SOIL EROSION AND SEDIMENT CONTROL MEET THE REQUIREMENTS, STANDARDS AND SPECIFICATIONS OF THE COUNTY CONSERVATION DISTRICT.”

(b) “I CERTIFY THAT ALL CONSTRUCTION AND/OR DEVELOPMENT WILL BE DONE AS DESCRIBED BY THIS PLAN OF DEVELOPMENT AND THE PLAN FOR SOIL EROSION AND SEDIMENT CONTROL, INCLUDING THE NARRATIVE REPORT.”

(5) The narrative report shall contain:
(a) A general statement of the project which shall contain:
1. A general description of the project;
2. A general description of stormwater control methods;
3. A general description of accelerated erosion control; and
4. A general description of sedimentation control.
(b) The staging of earthmoving activities, including cover removal, control facility installation, installation of improvements and program of operations; and
(c) A maintenance program for the control facilities, including:
1. Frequency of inspection of control facilities, and a method of disposal of materials removed from the control facilities of the project area;
2. The methods, frequency and ultimate disposal site for solid waste material. Construction waste shall be removed from the site and disposed of in an approved landfill. Construction waste shall not be buried on the site;
3. A specification for both temporary and permanent seeding, including preparation of the seed bed. Application rates for seed, fertilizer and mulch shall be provided, and shall comply with the specifications and standards established by the County Conservation District.
(6) The following items shall be shown on a map and also described in the narrative report:
(a) Temporary control measures and facilities for use during earthmoving, including:
1. Purpose;
2. Types of control measures and facilities;
3. Location of control measures and facilities; and
4. Dimensioned construction details of the facilities.
(b) Permanent control measures and facilities for site restoration and long-term protection, including:
1. Purpose;
2. Types of control measures and facilities;
3. Location of control measures and facilities;
4. Dimensioned construction details of the facilities; and
5. Design considerations and calculations.
(7) All erosion and sediment control facilities shall be periodically inspected and checked for adequacy and compliance with the approved erosion and sediment control plan by the borough. The approved erosion and sediment control plan shall be maintained at the site of earthmoving at all times.
(C) All control facilities shall be maintained for their designed operation to ensure adequate performance.
(D) The following guidelines shall be followed as needed in developing erosion and sediment control measures.
(1) Stripping of vegetation, grading, filling, excavating or other alteration of the landscape shall be kept to a minimum and shall be done in such a way that will minimize erosion.
(2) Whenever feasible, natural vegetation shall be retained, protected and supplemented.
(3) The disturbed area and the duration of exposure shall not exceed 20 days, except in the case of building construction.
(4) Disturbed soils shall be stabilized as quickly as practicable.
(5) Temporary vegetation and/or mulching shall be used to protect exposed critical areas during development.
(6) Erosion control and drainage measures shall be installed prior to earthmoving activities.
(7) Both permanent and temporary provisions shall be made to effectively accommodate the increased runoff caused by changed soil and surface conditions during and after development. Where necessary, the rate of surface water runoff shall be mechanically retarded.
(8) Until disturbed areas are stabilized, sediment in runoff water shall be trapped by the use of debris basins, sediment basins, silt traps or other similar approved measures.
(E) The following guidelines shall be applied as needed in excavation and fills as part of erosion and sediment controls.
(1) All lots, tracts or parcels shall be graded to provide positive drainage away from buildings, without ponding.
(2) Grading and cut-fill operations shall be kept to a minimum to ensure conformity with the natural topography, to minimize the erosion hazard, and to adequately handle surface runoff.
(3) Natural drainage patterns shall be preserved wherever possible and desirable.
(4) Adequate provisions shall be made to prevent surface water from damaging the cut face of excavations and the sloping surfaces of fills.
(5) Cut and fills shall not impact adjoining property.
(6) Fill shall be placed and mechanically compacted to minimize sliding and erosion of the soil.
(7) Fills shall not encroach on natural watercourses, floodplains or channels.
(8) During grading operations, necessary measures for dust control shall be exercised.
(9) Grading equipment shall not cross running streams. Provisions must be made for the installation of culverts or bridges.
(10) Whenever sedimentation is caused by stripping vegetation, regrading or other development or earthmoving, it shall be the responsibility of the developer, causing such sedimentation, at his or her expense, to remove it from all adjoining surfaces, drainage systems and watercourses and to repair any damage which was caused within 72 hours of such sedimentation or damage. The Borough Council may require a note to this effect to be placed on the final plan.
