[Ord. 776, 6/21/1993, § 501]
If the Zoning Officer has reason to believe that the proposed
use may have difficulty complying with the standards of this Part,
then the Zoning Officer may require an applicant to provide written
descriptions of proposed machinery, hazardous substances, operations
and safeguards.
[Ord. 776, 6/21/1993, § 502]
1.
No land owner, tenant or lessee shall use or allow to be used land
or structures in a way that seriously threatens to or creates any
of the following conditions:
B.
Significant physical hazards to the public, especially hazards that
would be easily accessible by small children.
C.
Activity that prevents a neighboring landowner of ordinary sensitivities
from making reasonable use of his/her property.
E.
Activity that causes serious pollution to groundwaters or surface
waters.
2.
It is the responsibility of every property owner to ensure that his/her
property does not threaten public health or safety, and to remove
or alter any structure or situation that threatens the public health
and safety. This includes, but is not limited to, structurally unsound
structures, including those damaged by fire.
[Ord. 776, 6/21/1993, § 503; as amended by Ord.
802, 9/19/1994, § 2]
1.
If the Borough Engineer, Planning Commission or Borough Council has
reason to believe that a portion of a site proposed to be altered
may possibly meet the state or federal definitions of a "wetland,"
the applicants(s) may be required to provide a study, prepared by
a qualified professional, which delineates that location of said wetlands.
In addition to this study, all wetlands located on this site shall
be properly identified, via metes and bounds descriptions with a reference
tie to the perimeter property survey, on the corresponding subdivision
and/or land development plan for the proposed development. Please
note, however, that the Borough accepts no responsibility to identify
all wetlands, or to warn all parties of such possibilities.
2.
A certification, which states that either the wetland area(s) shown
have been delineated in accordance with current state and/or federal
guidelines or that no wetlands exist on this site, shall be placed
on all subdivision and/or land development plans and signed by a qualified
professional.
3.
If it is found that the proposed work will be performed in wetlands,
a Borough permit shall not be issued until such time as all necessary
permits and approvals are first obtained from the appropriate federal
and/or state agencies by the applicant(s). Copies of all federal and
state permits and approvals shall be filed by the applicants(s) with
the Borough at the time of permit application.
[Ord. 776, 6/21/1993, § 504; as amended by Ord.
940, 1/7/2002, § 3]

Purposes. To protect the water quality of surface waters, preserve
physical access to surface waters in case of future public acquisition,
minimize erosion and sedimentation, preserve the natural stormwater
drainage system of the area, conserve sensitive wildlife and aquatic
habitats, preserve vegetation along waterways that will help screen
out eroded soil and other pollutants and provide for setbacks that
can be used as required yard areas for a use.
2.
Setback From Liebert's Creek and Major Drainage Channels. No building or paved area (other than approved street and driveway crossings) shall be located within: (A) 50 feet of the center of Liebert's Creek; or (B) within 10 feet of the center of a segment of a drainage channel if such drainage channel is mapped as floodplain on the Official Floodplain Map. See the Official Floodplain Map in case a wider area is regulated under § 27-516 of this chapter.
3.
Exemption. The setbacks of this section shall not apply to public
utility facilities or publicly-owned recreational facilities.
4.

activity, all reasonable efforts shall be made to leave the setback
areas of this section undisturbed, except at approved waterway crossings.
[Ord. 776, 6/21/1993, § 505; as amended by Ord.
940, 1/7/2002, § 2]
1.
Site Plan. If an area of a lot including slopes of 15% or greater
is proposed for construction of buildings, streets or driveways or
nonagricultural grading, then the applicant shall submit a steep slope
site plan to the Zoning Officer. These submittal requirements may
be met by including the required information on subdivision/land development
plans.
2.
Submission Requirements. A steep slope site plan shall meet the following
requirements:
A.
Show detailed existing and proposed slope contours for all areas
that potentially may be disturbed and/or constructed upon.
B.
Identify all areas of 15% to 25% and greater than 25% slope.
C.
Be to scale (such as one inches equals 50 feet).
D.
Show substantial areas of trees and dense vegetation proposed to
be removed or preserved prior to or during the development of the
use.
E.
Be stamped by a professional surveyor, professional engineer, registered
landscape architect or registered architect.
F.
Show proposed locations of principal buildings, streets, driveways,
on-lot septic fields and other areas of soil disturbance.*
G.
State the maximum slope of proposed driveways and streets.
H.
Show an area of 20 feet around the proposed principal building locations.
*If the exact location of these features is not definitely determined
at the time of plan submittal, then the plan shall designate the outer
limits of areas where such features may potentially be located. If
different locations outside of the approved location would be proposed
after approval of the site plan, then the applicant shall prove to
the Zoning officer that the revised location would still meet the
requirements of this section.
3.
Fifteen Percent to 25%. If, within the C-R district, a proposed principal
building location and any areas within 20 feet of such location on
the lot include more than 500 square feet with 15% or greater slopes,
but do not include more than 500 square feet with slopes greater than
25%, the following regulations shall apply, unless more restrictive
regulations are stated elsewhere in this chapter:
4.
Greater Than 25%. If, within the C-R district, a proposed principal
building location and any areas within 20 feet of such location on
the lot include more than 500 square feet with slopes greater than
25%, then the following regulations shall apply, unless more restrictive
regulations are stated elsewhere in this chapter:
5.
Streets, Driveways and Septic Systems. See applicable slope standards in the Borough Subdivision and Land Development Ordinance [Chapter 22]. See also Department of Environmental Protection regulations on slopes of on-lot septic systems.

that state erosion and sedimentation regulations and any officially
submitted erosion and sedimentation plan are complied with. The Zoning
Officer may require the submittal of an erosion and sedimentation
control plan with review by the County Conservation District wherever
soil will be disturbed. Failure to comply with such regulations or
plan shall be cause for suspension of Borough permits.
3.
Unstable Slopes. Slopes that would have the serious threat of instability,
in the determination of the Borough Engineer, shall not be created.
The Zoning Officer may require that the applicant provide certification
from a professional engineer that finished slopes greater than 4:1
will be stable.
4.
Drainage. The ground adjacent to a building shall be graded so that
surface water will be drained away from such building.
5.
Grading, excavation or movement of materials shall not be completed
in such a way that soils, rocks or other debris are left in an unsightly
fashion nor in a fashion that interferes with drainage, streets or
utilities.
[Ord. 776, 6/21/1993, § 513]
1.
Placement. Whenever reasonable, commercial, industrial and institutional
outdoor machinery that could create a noise nuisance shall be placed
towards a side of a building that does not face an abutting existing
dwelling, residential district, school or other noise sensitive use.
2.

[Ord. 776, 6/21/1993, § 516; as amended by Ord.
940, 1/7/2002, §§ 1-3, 6, 9]
1.
Purposes.
A.
To regulate development in areas of the Borough where streams are
known to possess flooding characteristics and/or chronic wetness which,
if indiscriminately developed, could pose hazards to the public health,
safety and welfare due to flood and pollution and to regulate development
in areas of known flooding in the Borough.
B.
To reduce the financial burden imposed on the Borough, its governmental
units and its individuals by frequent and periodic floods and overflows
on lands.
C.
To permit certain uses which can be appropriately located in such
areas and which will not impede the flow of flood waters, or otherwise
cause danger of life and property at, above or below their locations
along areas subject to flooding.
D.
To provide sufficient drainage courses to carry abnormal flows of
stormwater in periods of heavy precipitation.
E.
To regulate development in flood hazard areas in accordance with
the Federal Insurance Administration's requirements for flood
management and the Pennsylvania Floodplain Management Act, 32 P.S.
§ 679.101 et seq.
2.
Designations. Flood hazard areas are designated and interpreted as
follows:
A.
Identification of Floodplain Ares.
(1)
Identification. The identified floodplain area shall be those
areas of the Borough of Emmaus which are subject to the one-hundred-year
flood, as identified in the Flood Insurance Study (FIS) dated November
7, 2001, and the accompanying maps prepared for the Borough by the
Federal Emergency Management Agency (FEMA), or the most recent revision
thereof.
(2)
Description of Floodplain Areas. The identified floodplain area
shall consist of the following specific areas:
(a)
FW (Floodway Area). The areas identified as "Floodway" in the
AE Zone in the Flood Insurance Study prepared by the FEMA. The term
shall also include floodway areas which have been identified in other
available studies or sources of information for those floodplain areas
where no floodway has been identified in the Flood Insurance Study.
(b)
FF (Flood-Fringe Area). The remaining portions of the one-hundred-year
floodplain in those areas identified as an AE Zone in the Flood Insurance
Study, where a floodway has been delineated.
The basis for the outermost boundary of this area shall be the
one-hundred-year flood elevations as shown in the flood profiles contained
in the Flood Insurance Study.
(c)
FA (General Floodplain Area). The areas identified as Zone A
in the FIS for which no one-hundred-year flood elevations have been
provided. When available, information from other federal, state, and
other acceptable sources shall be used to determine the one-hundred-year
elevation, as well as a floodway area, if possible. When no other
information is available, the one-hundred-year elevation shall be
determined by using a point on the boundary of the identified floodplain
area which is nearest the construction site in question.
In lieu of the above, the Borough may require the applicant
to determine the elevation with hydrologic and hydraulic engineering
techniques. Hydrologic and hydraulic analyses shall be undertaken
only by professional engineers or others of demonstrated qualifications,
who shall certify that the technical methods used correctly reflect
currently accepted technical concepts. Studies, analyses, computations,
etc., shall be submitted in sufficient detail to allow a thorough
technical review by the Borough.
(3)
Changes in Identification of Area. The identified floodplain
area may be revised or modified by the Council where studies or information
provided by a qualified agency or person documents the need for such
revision. However, prior to any such change, approval must be obtained
from the Federal Insurance Administration (FIA).
B.
When exact measurements do not exist, the boundaries of the flood
hazard areas shall be determined by scaling distances off the Flood
Insurance Rate Map. A person who contests the location of a boundary
as shown on the map and is denied a permit shall appeal the denial
to the Zoning Hearing Board. The person contesting the location of
a flood hazard area shall have the burden of establishing that the
land does not lie within a flood hazard area.
C.
Records of elevations of the lowest floor (including basement) and
floodproofing levels shall be obtained and maintained for all new
or substantially improved structures in the flood hazard areas and
shall indicate whether or not such structures contain a basement.
D.
With any FW (Floodway Area), the following provisions apply:
(1)
Any new construction, development, use, activity, or encroachment
that would case any increase in flood heights shall be prohibited.
(2)
No new construction or development shall be allowed, unless
a permit is obtained from the Department of Environmental Protection,
Bureau of Dams, Waterways and Wetlands.
E.
Within any FE (Special Floodplain Area) or FA (General Floodplain
Area), the following provisions apply:
(1)
No new construction or development shall be located within the
area measured 50 feet landward from the top-of-bank of any watercourse,
unless a permit is obtained from the Department of Environmental Protection,
Bureau of Dams, Waterways and Wetlands.
(2)
No new construction or development shall be located within the
area measured 50 feet landward from the top-of-bank of any watercourse.
(3)
Any new construction or development, which would cause any increase
in flood heights, shall be prohibited within any floodway area.
F.
Elevation and Floodproofing Requirements.
(1)
Residential Structures. Within any identified floodplain area,
any new construction or substantial improvement of a residential structure
shall have the lowest floor (including basement) elevated up to, or
above, the regulatory flood elevation.
(2)
Non-residential Structures.
(a)
Within any identified floodplain area, any new construction
or substantial improvement of a non-residential structure shall have
the lowest floor (including basement) elevated up to, or above, the
regulatory flood elevation, or be designed and constructed so that
the space enclosed by such structure shall remain either completely
or essentially dry during any flood up to that height.
(b)
Any non-residential structure, or part thereof, having a lowest
floor which is not elevated to at least 1 1/2 feet above the
one-hundred-year flood elevation shall be floodproofed in a completely
or essentially dry manner in accordance with the WI or W2 space classification
standards contained in the publication entitled "Flood-Proofing Regulations"
published by the U.S. Army Corps of Engineers (June 1972, as amended
March 1992) or which some other equivalent standard. All plans and
specifications for such floodproofing shall be accompanied by a statement
certified by a registered professional engineer or architect which
states that the proposed design and methods of construction are in
conformance with the above referenced standards.
(3)
Space Below the Lowest Floor.
(a)
Fully enclosed space below the lowest floor (including basement)
is prohibited.
(b)
Partially enclosed space below the lowest floor (including basement)
which will be used solely for the parking of a vehicle, building access,
or incidental storage in an area other than a basement, shall be designed
and constructed to allow for the automatic entry and exit of flood
waters for the purpose of equalizing hydrostatic forces on exterior
walls. The term "partially enclosed space" also includes crawl spaces.
Designs for meeting this requirement must either be certified
by a registered professional engineer or architect, or meet or exceed
the following minimum criteria:
(i)
A minimum of two openings having a net total area
of not less than one square inch for every square foot of enclosed
space.
(ii)
The bottom of all openings shall be no higher
than one foot above grade.
(iii)
Openings may be equipped with screens, louvers,
etc., or other coverings or devices provided that they permit the
automatic entry and exit of floodwaters.
3.
Permits Required in Flood Hazard Areas.
B.
A permit is required for all proposed construction, development and
any man-made change to improved or unimproved real estate including,
but not limited to, buildings or other structures, mining, dredging,
filling, grading, paving, excavation or drilling operations.
C.
All necessary permits shall have been received from governmental
agencies from which approval is required by federal or state law,
including provisions of the U.S. Water Pollution Control Act of 1972.

1.
Purpose. The purpose of this section is to recognize the potential
for damage to public and private improvements, human injury or death,
and the disruption of vital public services which may arise by the
potential for sinkholes and/or subsidence within areas of carbonate
geology. A further purpose of this section is to minimize the potential
for such sinkhole and/or subsidence occurrence and to protect the
ground water resource. Should the regulations of this and other applicable
regulations conflict, the most stringent regulations shall apply.
2.
Disclaimer of Liability. Wheras the exact occurrence of sinkholes
and/or subsidence is not predictable, the administration of these
regulations shall create no liability on behalf of the Borough Engineer,
Borough employees or Borough agencies as to damages which may be associated
with the formation of sinkholes or subsidence. That is, compliance
with these regulations represents no warranty, finding, guarantee,
or assurance that a sinkhole and/or subsidence will not occur on an
approved property. The Borough, its agencies, consultants and employees
assume no liability for any financial or other damages which may result
from sinkhole activity.
3.
Karst Hazard Indicator Map. Areas of the Borough in which Karst features
are believed more likely to be present are shown on the Karst Indicator
Map at the end of this chapter. These areas of the "carbonate" areas
shown on the map. The sinkholes, quarries, limonite excavations, solution
pans, closed, semi-closed or linear depressions and iron surface mines
delineated on the Karst Hazard Indicator Map were taken from two sources.
(1) Sinkholes and Karst related features mapping for Lehigh County
prepared by the Commonwealth of Pennsylvania Department of Environmental
Resources, Bureau of Topographic and Geologic Survey (open file report
8701); (2) the Little Lehigh Creek Basin Carbonate Prototype Area
Closed Depression Map prepared by R.E. Wright Associates, Inc. The
Karst Hazard Indicator Map is intended as a tool to assist applicants
and the Borough in identifying Karst hazard areas. However, the Karst
Hazard Indicator Map is not the exclusive tool for locating Karst
features. The Borough shall also utilize generally accepted geological
techniques to locate such features.
4.
Procedures.
A.

inch to 100 feet that shows the Karst features listed in subsection
(4)(B).
D.
Based upon the site inspection, the applicant's professional
shall determine what further testing should be done by the applicant
to ensure compliance with performance standards set forth in subsection
(4)(B). Testing methodology shall be reasonable under the circumstances,
including (1) the scale of the proposed development; and (2) the hazards
revealed by examination of available data and site inspection.
E.
The applicant shall cause the additional testing, if any to be effected,
and shall submit test results to the Borough Engineer.
F.
The Borough Engineer shall report to the Borough Planning Commission
and/or Council, with a copy to the applicant, his opinion concerning
the adequacy of the report submitted based upon the scale of the development
and the hazards revealed by the report, and shall make recommendations
to the Planning Commission and/or Council based upon the report submitted
concerning site development, including stormwater management, the
layout of utility lines and building location. The Borough Engineer
may require the applicant to perform such additional testing as may
be appropriate.
