[1]
Note: Slopes in excess of 15% (15 feet vertical distance over one 100 feet horizontal distance).
A. 
If a reasonable doubt exists whether a portion of a site would meet the federal and/or state definition of a "wetland," the applicant is required to provide a wetlands delineation study by a qualified professional. A description of the qualifications of the person who accomplished the delineation shall be provided to the Township.
B. 
All applicants are put on notice that federal regulations may require a property owner to demolish newly constructed buildings and to remove all fill if land meeting a definition of "wetland" is altered.
C. 
All permits of the Township are issued on the condition that the applicant comply with federal and state wetlands regulations.
A. 
Intent: to protect the water quality of surface waters in the Township; to preserve physical access to surface waters in case of future public acquisition; to minimize erosion and sedimentation; to preserve the natural stormwater drainage system of the area and to conserve sensitive wildlife and aquatic habitats. The areas within these setbacks may be used for the required yard areas for a use.
B. 
Setbacks from major surface waters.
(1) 
No new structure, impervious surface, off-street parking or commercial or industrial storage or display area shall be located within 75 feet of the top edge of each closest bank of a major surface water. See the Township floodplain map in case a wider area is regulated under Chapter 135, Floodplain Management.
(2) 
The exact location of the top edge of the bank shall be determined by the Township Engineer. Major surface waters are defined as the Lehigh River and the Monocacy Creek.
C. 
Setbacks from minor surface waters. No new building, impervious surface, off-street parking or commercial or industrial storage or display area shall be located within 50 feet of the center of the water of any minor surface waters. Minor surface waters are defined as the Nancy Run Creek.

Definition. Alluvial soils are areas designated as such by the U.S. Natural Resources Conservation Service County Soil Survey.
B. 
Applicability of Chapter 135, Floodplain Management. If construction or grading is proposed within an area that has been designated as alluvial soils along a creek or drainage swale segment that has not been included in the federal one-hundred-year floodplain study, the applicant shall complete a study to determine the extent of the one-hundred-year floodplain.
C. 
Study. The study shall be accomplished to federal floodplain methodology by a person who is clearly accomplished in floodplain studies. The full cost of the study and any review by the Township Engineer shall be borne by the applicant.
D. 
Effect. Within any area determined to be within the one-hundred-year floodplain, the regulations of Chapter 135, Floodplain Management, as amended, shall apply.
E. 
Option. The applicant may choose not to have a floodplain study accomplished. In such case, the alluvial soils areas along unstudied segments shall be required to meet the same requirements as the one-hundred-year floodway.
A. 
All nonagricultural activities which require the moving of earth or the filling or excavating of an area greater than one acre, or the removal of more than five trees with a trunk diameter of six inches or more (measured at a height of one foot above the original grade), shall submit a plan to the Township showing site grading and erosion control measures prior to start of such work. These plans shall be subject to reviews by the Township Engineer and the County Conservation District. See also § 275-138, Preservation of trees and forests.
B. 
Grading regulations.
(1) 
Slopes that would have the serious threat of instability, in the determination of the Township Engineer, shall not be created.
(2) 
The surface area of any yard adjacent to a building or structure shall be graded so that surface water will be drained away from such structure.

(4) 
The Zoning Officer or Township Engineer may require that a sedimentation and erosion plan be prepared, submitted to the County Conservation District for a review and complied with.
(5) 
Materials used for fill as a future base for construction shall be nonorganic and provide a suitable and secure base. The Board of Commissioners may require appropriate underground testing of a proposed building site if there is reasonable doubt in the opinion of the Township Engineer that the subsurface is suitable and secure for building.
(6) 
Steep slopes. If the grading is not clearly being done for agricultural purposes only, the steep slope provisions of § 275-124 shall thereafter regulate the property based upon the contours prior to regrading.
(7) 
Grading inspection and approval. The elevations of basement and garage floors, tops of foundation and finished first floor, primary on-lot sewage disposal systems, finished roads along the points of proposed ingress to a lot, and lot grading are subject to the requirements of § 275-9A(4)(c), and shall be subject to inspection and approval by the Township. The rough grading shall be compatible with the approved erosion and sedimentation control plan or support erosion control measures, and the application plot plan required by § 275-9A(4)(c).
[Amended 11-6-2000 by Ord. No. 07-00]

All uses or sources, including signs, shall minimize the production of light, heat or glare that is perceptible beyond any property line of the lot on which the light, heat or glare is produced.
C. 
Height of lights. No luminaire, spotlight or other light source that is within 200 feet of a dwelling or residential district shall be placed at a height exceeding 30 feet above the average surrounding ground level. This limitation shall not apply to lights needed for air safety nor lights intended solely to illuminate an architectural feature.
D. 
Diffused. All light sources, including signs, shall be properly diffused as needed with a translucent or similar cover to prevent exposed bulbs from being directly visible from abutting streets or lots. No spotlight shall be directed such that the bulb itself is directly visible from a public street or dwelling.
E. 
Shielding. All light sources, including signs, shall be shielded around the light source and carefully directed and placed to prevent the lighting from creating a nuisance to adjacent dwellings or residentially zoned areas, and to prevent the lighting from shining into the eyes of passing motorists.
F. 
Maximum candlepower. No lighting source, including signs, shall spill over a property line in such a way as to cause an illumination of greater than the following amounts, measured on the surface at the lot line of the receiving lot or street:
(1) 
One-tenth footcandle spillover at a residential lot line between the hours of 10:00 p.m. and 7:00 a.m.

Four footcandles spillover at any lot line other than a residential lot line or at a street right-of-way line.
G. 
Flickering. Flashing, flickering or strobe lighting is prohibited, except for Christmas lights between November 15 and January 3.
H. 
Measurement. The maximum illumination levels of this section shall be measured with a photoelectric photometer having a spectral response similar to that of the human eye. The standards of the International Commission on Illumination shall serve as a general guide in measurements in case of uncertainty. A "footcandle" is defined as a unit of measurement equaling the illumination on a surface one square foot in area where there is a distribution of light having a candlepower of one candela.
A. 
Noise. No outdoor machinery, such as exhaust fans, central air conditioning units, power generators or high-voltage electric transformers shall routinely produce noise that would violate the noise standards of § 275-132.
B. 
Placement. Whenever reasonable, outdoor machinery that could create a noise nuisance shall be placed on a side of a commercial or industrial building that does not face an abutting existing dwelling, residential district or other noise-sensitive use.
C. 
Safety. Hazards involving outdoor machinery shall be well-marked. Adequate fencing shall be provided as needed to keep children away from hazardous machinery and equipment.

B. 
No radioactive wastes shall be disposed of in any district and no radioactive wastes shall be stored on a lot for longer than 90 days after their permitted use is completed.
A. 
Intent. To protect wildlife and bird habitats, encourage groundwater recharge, avoid pollution of creeks by high temperature runoff, maintain the attractive character of areas and conserve energy.
B. 
Tree removal. All trees with a trunk diameter of six inches or more (measured at a height 3.5 feet above original grade) shall not be removed as part of the development of a use unless they are located within a proposed vehicular cartway, stormwater detention basin, parking area, sidewalk portion of the right-of-way, or driveway, within the on-site sewage system, within 20 feet of the foundation area of a structure or unless they are diseased, pose a clear danger to a building or are excessive in number and thinning will clearly promote and enhance the healthy development of the remaining trees.
C. 
Protection of trees during construction. Reasonable efforts shall be taken during any construction to ensure that trees protected by this section are not accidentally injured or removed, including root compaction by equipment and materials, mechanical damage or change in grade level.
(1) 
An area under the "dripline" of branches of trees to be preserved should be designated as a tree protection area. A substantial temporary fence with temporary signs and with a minimum height of four feet should be used to surround such tree protection area to prevent vehicles and equipment from damaging trees and compacting roots.
D. 
Applicability. This section shall not apply to an owner of a residential use after a certificate of occupancy has been granted.
E. 
Forestry. This section is not intended to apply to commercial forestry, which is regulated as a district land use.
F. 
Preservation of trees within buffer areas. See § 275-171D(3)(c).
A. 
Definition. Performance standards shall mean the requirements of this article.
B. 
Intent. To ensure that all uses, especially industrial uses involving complex or unusual processes, comply with the performance standards of this chapter and do not threaten the public health and safety.
C. 
Information required. The Zoning Officer or the Zoning Hearing Board may require an applicant to submit sufficient information on any storage, manufacture or processing of materials that might involve explosive, toxic, hazardous or radioactive substances to determine whether the use would meet the performance requirements of this chapter.
D. 
Zoning Hearing Board review. If a reasonable doubt exists whether a proposed use would meet the performance standards of this chapter, the Zoning Officer may request a review by the Zoning Hearing Board.
E. 
Studies may be required. As part of a review by the Zoning Hearing Board of a special exception use or a review requested by the Zoning Officer, the Zoning Hearing Board may require an applicant for a zoning permit to fund such reasonable and necessary studies to determine the use's compliance with the performance standards. Such studies shall be completed by expert(s) selected by the Zoning Hearing Board, upon recommendation of the Township Staff. Such studies should, whenever possible, be completed in written form within 45 days of the application for a zoning permit.
(1) 
Cooperation. The applicant shall be required to provide such information to the designated reviewer to allow an accurate determination of potential hazards.
F. 
Monitoring. If a reasonable doubt exists that a use would violate the performance standards, the Zoning Hearing Board may require a use to fund such reasonable and necessary monitoring to ensure its compliance.
G. 
Backup systems. The Zoning Hearing Board may require a use to provide a separate secondary safeguard system to protect the public from serious nuisances and hazards under the performance standards.
The permanent stripping and removal of topsoil from any lot is prohibited, except on portions of a lot for which approval has been received to construct a building or paving. This shall not restrict the temporary stockpiling of topsoil during construction, nor routine crop farming practices.
A. 
Applicability. This section shall apply to permit applications for the construction of a new principal building that will not be regulated under Chapter 230, Subdivision and Land Development. (Note: Separate provisions in Chapter 230, Subdivision and Land Development, require more involved review and approval for activities regulated by that ordinance.)
B. 
Any person applying for a permit for a new principal building shall identify the approximate location of any known or suspected sinkholes on the property. Also, isolated low points on the site (known as "closed topical depressions") shall also be identified.
C. 
If the Zoning Officer has reason to believe that a proposed building site may be vulnerable to sinkholes, the Zoning Officer may, but is not required to, require that the applicant provide evidence from a qualified professional that proper methods will be used in the development of the site to minimize the threat of sinkholes and subsidence.
D. 
Stormwater shall not be redirected into a sinkhole.
E. 
Disclaimer. Whereas the exact occurrence of sinkholes is not predictable, the administration of these regulations shall create no liability on behalf of the Township, the Township Engineer, Township employees or any Township agency as to damages which may be associated with sinkhole formation. Compliance with these regulations represents no warranty, finding, guarantee or assurance that a sinkhole will not occur on an approved property. The Township, its agencies, consultants and employees assume no liability for any financial or other damages which may result from sinkhole activity.
