[HISTORY: Adopted by the Borough Council of the Borough of Pennsburg 9-11-2007 by Ord. No. 6-07. Amendments noted where applicable.]
This chapter shall be known and may be cited as the "Pennsburg Borough Grading Ordinance."
The purposes of this chapter are to regulate the modification of the natural terrain, the alteration of drainage, and to provide for certain erosion and sediment control measures within the Borough of Pennsburg and to assure and safeguard health, safety, ecology and the general welfare in the Borough of Pennsburg.
From and after the effective date of this chapter, any grading, paving, earth disturbance and alteration of drainage within the Borough of Pennsburg shall be in conformity with this chapter. In the event of a conflict between this chapter and the Borough of Pennsburg Stormwater Management Ordinance, the Borough of Pennsburg Stormwater Management Ordinance shall take precedence.
If any section, subsection, sentence, clause or phrase of this chapter is for any reason held to be invalid or unconstitutional by the decision of any court of competent jurisdiction, such decision shall not affect the validity of the remaining portions of the chapter.
As used in this chapter, the following terms shall have the meanings indicated, unless a different meaning clearly appears from the context:
- ALLUVIAL SOILS
- An agonal great group of soils, developed from transported and relatively recently deposited material (alluvium), characterized by a weak modification (or none) of the original material by soil-forming processes.
- CUT and/or FILL
- Process of earthmoving by excavating part of an area and/or using excavated material for embankments or fill areas.
- The flat or nearly flat land adjacent to a stream or river that experiences occasional or periodic flooding; the floodplain includes the floodway.
- That portion of the floodplain including the watercourse channel and adjacent land areas which must be reserved to the one-hundred-year recurrent interval flood without cumulatively increasing the flood elevation more than one foot.
- A. The slope of a road, driveway, channel or natural ground.
- B. The finished surface of a canal bed, roadbed, top of embankment or bottom of excavation; any surface prepared for the support of construction, like paving or laying a conduit.
- C. To finish the surface of a canal bed, roadbed, top of embankment or bottom of excavation.
- RUNOFF (HYDRAULICS)
- That portion of the precipitation on a drainage area or watershed that is discharged from the area in stream channels; types include surface runoff, groundwater runoff or seepage.
- Solid material, both mineral and organic, that is in suspension, is being transported, or has been moved from its site or origin by air, water, gravity or ice, and has come to rest on the earth's surface either above or below sea level.
- Degree of deviation of a surface from the horizontal, usually expressed in percent or degrees.
- SOIL DRAINAGE
- A condition of the soil, referring to the frequency and duration of periods when the soil is free of saturation.
- A natural or man-made drainage route or channel for the flow of water.
Whenever the landscape is to be permanently disturbed as to either contours, soil or slope characteristics, or vegetation or any ground cover is to be permanently removed, a plan is required showing how resulting erosion and sediment shall be controlled. This plan shall include, but not be limited to, the following information in accordance with Chapter 102 of the Pennsylvania Department of Environmental Protection Soil Erosion Control Manual:
The amount of site alteration and/or disturbance proposed;
Erosion and sediment control practices (both temporary and permanent) and the operation and maintenance arrangements; and
The following activities require a grading permit:
Modifying, disturbing, blocking, diverting or otherwise affecting the natural overland or subsurface flow of stormwater.

The results of the investigation shall be presented in a report by a registered professional soils engineer and shall include data regarding the nature, distribution and supporting ability of existing soils and rocks on the site, conclusions and recommendations to insure stable soil conditions and groundwater control, as applicable. Pennsburg Borough may require such supplemental reports and data as are deemed necessary by the Borough Engineer. Recommendations included in such reports and approved by the Borough Engineer shall be incorporated in the plan or specifications. In addition:
Fills toeing out on natural slopes steeper than four horizontal to one vertical shall not be made unless a report is received which is deemed acceptable by the Borough Engineer and approved by the Borough Council. The report shall be made by a registered professional soils engineer certifying that he has investigated the property, made soils tests and that, in his opinion, such steeper slopes will safely support the proposed fill.
Natural and/or existing slopes exceeding five horizontal to one vertical shall be benched or continuously stepped into competent materials prior to placing all classes of fill.
Upon the approval of the plan by the Borough Engineer, the Building Inspector/Zoning Officer shall issue the necessary grading permit in letter form.
Every grading permit shall expire by limitation and become null and void if the work authorized by such permit has not been commenced within six months or is not completed within one year from the date of issue, provided that the Borough Engineer may, if the permit holder presents satisfactory evidence that unusual difficulties have prevented work from being started or completed within the specified time limits, grant a reasonable extension of time, and, provided, further, that the application for the extension of time is made before the date of expiration of the permit.
Notwithstanding any provisions of this chapter or any condition of the grading permit, the permittee is responsible for the prevention of damage to other property, or personal injury, which may be effected by the activity requiring a grading permit.
No person, firm or corporation shall modify, fill, excavate, pave, grade or regrade land in a manner so close to a property line as to endanger or damage any adjoining street, alley, or any other property from settling, cracking, erosion, sediment, flooding or any other physical damage or personal injury which might result.
No person, firm or corporation shall deposit or place any debris or any other material whatsoever, or cause such to be thrown or placed, in any drainage ditch or drainage structure in such a manner as to obstruct free flow.
No person, firm or corporation shall place any fill in any portion of any floodway within the Borough.

Degree of compaction required shall be determined by the Borough Engineer, following the guidelines in this section.
All inspections shall be the responsibility of the Borough Engineer or, in his absence, a qualified person acceptable to the Borough Engineer and Pennsburg Borough.
Inspections will be carried out on a random basis, except as stated below. However, a set of as-built plans shall be submitted to the Borough and on file at the site and authenticated by a registered professional surveyor. When it is deemed acceptable to the Borough Engineer, a designated qualified person may authenticate the as-built plans and will assume full responsibility for the quality of the work.
As-built plans shall be required at the following stages of construction:
Stake-out of the building;
After the foundation footer is in place and prior to the erection of the foundation walls; and
After the completion of the finished grading of the entire lot and prior to the placement of any topsoil or landscaping. Grading shall take into consideration the requirement of a minimum of six inches of topsoil.
Any and all as-built plans shall be available on the site at all times and subject to inspection and inquiry.
Engineering check notes shall accompany all as-built plans which involve structural or mechanical measures and shall serve as supporting evidence that structures meet design standards and specifications specified herein.
A final inspection shall be conducted by the Borough Engineer to certify compliance with this chapter. Satisfactory compliance with this chapter shall be necessary before the issuance of any occupancy or use permit.
Permittees shall bear all costs of inspection required or permitted hereunder and shall deposit with the Borough such sum as the Borough Council shall determine to guarantee payment of the costs of such inspections. The costs of inspections shall be in accordance with the established schedule of fees and collection procedures for matters pertaining to this chapter.
A fee, in an amount as established from time to time by resolution, is required upon initial submission of an application. Cost of all inspections (other than the initial inspection and the final inspection) will be billed to the applicant as inspections are completed at a rate, in an amount as established from time to time by resolution, per inspection. Payments shall be made within 30 days, and no occupancy permit will be issued until all payments have been made.
Any permit issued under this chapter may be revoked or suspended by the Pennsburg Borough Council, after notice for:
Failure to carry out the control measures described in the application at the appropriate times as specified in the applicable time schedule or within such reasonable extension as may be granted by the Borough Council;
Violation of any other condition of the permit;
Violation of any provision of this chapter or any other applicable law, ordinance, rule or regulation relating to the work; and
Existence of any condition or the doing of any act consisting or creating a nuisance, hazard or endangering human life or the property of others.
The Borough Engineer, before issuing a permit for a project, may require cash bond or corporate surety bond in a form satisfactory to the Borough Council conditioned upon the faithful performance of the control measures and other conditions specified in the permit within the time specified, or within an extension thereof granted by the Borough Council, in the amount of the total estimated cost of all control measures and safeguards for adjoining properties. Said bond may be combined with a bond filed under the Pennsburg Borough Subdivision and Land Development Ordinance. Each bond shall be maintained and renewed annually and shall be executed by a surety or guaranty company qualified to transact business in the state.
It shall be unlawful to operate a motor vehicle in such a way as to deposit mud, soil, silt, sediment, stones, muddy water, liquids from any trash or any other foreign materials of any kind onto public roads in the Borough.
The person(s) or entity operating the vehicle responsible for depositing such materials onto public streets shall cause them to be thoroughly cleaned up within two hours of written or verbal notice from the Borough or its agents.
If the person(s) or entity operating the vehicle cannot be identified, the person(s) or entity having control over the site from whence the materials originated shall cause them to be thoroughly cleaned up within four hours of written or verbal notice from the Borough or its agents.
In case of any paving, filling, stripping, grading or regrading, and disturbing, modifying, blocking or diverting the natural overland or subsurface flow of stormwater, or any construction, erection and installation of any dam, ditch, culvert, drain pipe, bridge or any other structure or obstruction affecting the drainage of any premises, in violation of this chapter or any regulations made pursuant thereto, the proper Borough authorities, in addition to other remedies provided by law, may institute any appropriate action or proceedings to prevent such unlawful activity, to restrain, correct or abate such violation, to prevent the use of the applicable premises, or to prevent any illegal act, conduct, business or use in or about such premises. In addition, upon the failure of any permit holder to complete the control measures specified in his application, the Borough may, after revoking such permit, proceed to complete such measures itself and recover the cost thereof from the permittee or his surety.
An applicant may file an appeal within 30 days from the date of any determination made by the Building Inspector/Zoning Officer under this chapter. The Borough Council shall have exclusive jurisdiction to hear and render final adjudication in all appeals from the determination of the Building Inspector/Zoning Officer in the administration of the provisions of this chapter.
