680, 12/28/1998]
1. The standards and requirements contained in this Part and Part 6
are intended as the minimum for the promotion of the public health,
safety and general welfare and shall be applied as such by the Borough
Planning Commission and Borough Council in reviewing all subdivision
and land development plans.
2. Whenever other Borough ordinances and/or regulations impose more
restrictive standards and requirements than those contained herein,
such other ordinances and/or regulations shall be observed; otherwise,
the standards and requirements of this chapter shall apply.
3. The standards and requirements of this chapter may be modified by
the Borough Council in the case of complete communities, neighborhood
units or other large scale developments upon the recommendation of
the Borough Planning Commission where such modifications achieve substantially
the objectives of this chapter and which are further protected by
such covenants or other legal provisions as will assure conformity
to and achievement of the subdivision/land development plan.
4. Land subject to hazards to life, health or property such as may arise
from fire, floods, disease or other causes shall not be subdivided
for building purposes unless such hazards have been eliminated or
unless the subdivision plan shall show adequate safeguards against
them which shall be approved by the appropriate regulatory agencies.
5. Subdivision/land development plans shall give due recognition to
the official plans of the Borough and of the County or to such parts
thereof as may have been adopted pursuant to statute.
6. Land proposed for subdivision shall not be developed or changed by grading, excavating or by the removal or destruction of the natural topsoil, trees or other vegetative cover unless adequate provisions for minimizing erosion and sediment are provided under Title 25, Chapter 102, Rules and Regulations, PennDEP and §
22-508 of this chapter.
[Ord. 614, 12/29/1992, § 502]
1. General Standards.
A. The location and width of all streets shall conform to the official
plans or to such parts thereof as may have been adopted by the Borough
Planning Commission and/or the Borough Council.
B. The proposed street system shall extend existing or proposed streets on the official plans at the same width or larger, but in no case at less than the required minimum width in subsection
(3).
C. Where, in the opinion of the Borough Planning Commission, it is desirable
to provide for street access to adjoining property, street stubs shall
be extended, by dedication, to the boundary of such property.
D. New minor streets shall be so designed as to discourage through traffic
but the subdivider shall give adequate consideration to provision
for the extension and continuation of major and collector streets
into and from adjoining properties.
E. Where a subdivision abuts or contains an existing street of improper
width or alignment, the Borough Planning Commission may require the
dedication of land sufficient to widen the street or correct the alignment.
F. Private streets (streets not to be offered for dedication) are prohibited
unless they meet the design and improvement standards of this chapter.
G. All design elements of all streets, including horizontal and vertical alignment, sight distance and superelevation, are subject to review and approval by the Borough. When reviewing the design of streets, in addition to the standards in this chapter, the Rural Design Criteria in the Pennsylvania Department of Transportation "Design Manual, Part
2, Highway Design," January 1990 edition, and "A Policy on Geometric Design of Highways and Streets," AASHTO, 1984 edition, shall be consulted to assure that the road design is in accordance with acceptable engineering practice.
H. For certain aspects of vertical and horizontal alignment discussed
below standards are determined by design speed of the road involved.
For all proposed streets the subdivider shall indicate the proposed
design speed. The designated design speed is subject to the approval
of the Borough. In general, the design speed on major streets shall
be considered as 55 miles per hour (to be determined in each individual
case), on collector streets a minimum of 35 miles per hour (to be
determined in each individual case) and on minor streets 35 miles
per hour, unless a lesser design speed is permitted by the Borough.
2. Partial and Half Streets. New half or partial streets shall be prohibited
except where essential to reasonable subdivision of a tract in conformance
with the other requirements and standards of these regulations and
where, in addition, satisfactory assurance for dedication of the remaining
part of the street can be obtained. Subdivider shall provide the entire
required cartway width within his property.

ingress and egress is proposed the Planning Commission may require,
where deemed necessary in the public interest and for the public safety,
the provision of additional accessways or the provision of an alternate
means of ingress and egress which could be used by emergency vehicles
if the primary means of ingress and egress were rendered unusable.
Such alternate means of ingress and egress shall be of such width
and improved to such an extent to be usable by emergency vehicles
and shall not be used for structures, trees or similar obstructions.
C. Whenever a subdivision abuts or contains an existing or proposed
street with an ultimate right-of-way of 80 feet or more or contains
or abuts an existing or proposed collector street, the Borough Planning
Commission or the Borough Council may require restriction of access
to said street by:

22-502(6) and deflections in alignment in excess of 5° shall be made by horizontal curves.
13. Access.
A. The location and number of access points to a subdivision or land
development shall be adequate for and appropriate to the size and
nature of the development and surrounding roads and land uses.
B. For all subdivisions and land developments for which only one means
of ingress and egress is proposed, the Planning Commission may require,
where deemed necessary in the public interest and for the public safety,
the provision of additional accessways or the provision of an alternate
means of ingress and egress which could be used by emergency vehicles
if the primary means of ingress and egress were rendered unusable.
Such alternate means of ingress and egress shall be of such width
and improved to such an extent to be usable by emergency vehicles
and shall not be used for structures trees or similar obstructions.

case the Borough Planning Commission or Borough Council may approve
a single tier of lots.
5. Commercial and Industrial Blocks. Blocks in commercial and industrial
areas may vary from the elements of design detailed above as required
by the nature of the use. In all cases, however, adequate provision
shall be made for off-street parking and loading areas as well as
for traffic circulation and parking for employees and customers.
[Ord. 614, 12/29/1992, § 504; as amended by Ord.
680, 12/28/1998]
1. General Standards.
A. Insofar as practical, side lot lines shall be at right angles to
straight street lines or radial to curved street lines.
B. Where feasible, lot lines shall follow municipal boundaries rather
than cross them in order to avoid jurisdictional problems.
C. Generally, the depth of residential lots shall be not less than one

either:
(1)
Incorporated in existing or proposed lots; or,
(2)
Legally dedicated to public use if acceptable to the Borough.
F. Flag lots are prohibited unless permission is granted by the Borough.
The Borough may grant permission to utilize flag lots when it deems
flag lots appropriate because of topographical or other conditions
unique to the site. The access strip portions of a flag lot must be

a minimum depth of 75 feet measured in the shortest distance from
the proposed dwelling unit to the ultimate right-of-way and shall
have within such rear yard and immediately adjacent to the right-of-way
a planting screen easement of at least 10 feet in width across which
there shall be no right of access.
D. After consideration of street speeds, traffic volumes, projected
traffic generated at a proposed land use and the location and arrangement
of existing and proposed driveways and intersections, the Borough
may require the subdivider to install at his expense an acceleration
or deceleration lane, or both, to serve a proposed driveway or street.
If additional street right-of-way is required to construct the acceleration
or deceleration lane, the additional right-of-way shall be provided
by the subdivider. When required by the Borough, the subdivider shall
furnish a study to the Borough which will provide the information
necessary to permit the determination as to whether an acceleration
or deceleration land is required.
E. For all subdivisions and land developments for which only one means
of ingress and egress is proposed, the Borough may require, where
deemed necessary in the public interest and for the public safety,
the provision of additional accessways or the provision of an alternate
means of ingress and egress which could be used by emergency vehicles
if the primary means of ingress and egress were rendered unusable.
Such alternate means of ingress and egress shall be of such width
and improved to such an extent to be usable by emergency vehicles
and shall not be used for structures, trees or similar obstructions.

[Ord. 614, 12/29/1992, § 505; as amended by Ord.
680, 12/28/1998]
1. Each property shall be connected to the Borough's sewer system,
if accessible. Where the Borough's sewer is not yet accessible,
but is planned for extension to the subdivision, the subdivider shall
install sewer lines, including lateral connections as may be necessary
to provide adequate service to each lot when connection with the sewer
system is made. The sewer lines shall be suitably capped at the limits
of the subdivision and the laterals shall be capped at the street
right-of-way line. When capped sewers are provided onsite disposal
facilities shall also be provided. Design of capped sewer system shall
be subject to approval by the Borough.

4. All lots which cannot be connected to a Borough sanitary sewage disposal
system in operation at the time of construction of a principal building
shall be provided with an onsite sanitary sewage disposal system consisting
of a septic tank(s) connected with a tile disposal field and which
shall, as a minimum requirement, meet the design standards of the
rules and regulations of the Pennsylvania Department of Environmental
Protection and Borough standards.
5. If onsite sanitary sewage disposal facilities are to be utilized,
the Borough Planning Commission may require that the subdivider submit
a feasibility report. Such report shall compare the cost of providing
onsite facilities and the cost of extending the public sewer system.
Based on the analyses of this report the Planning Commission may require
the installation of a public sewer system.
6. Where onsite sanitary sewage facilities are to be utilized, each
lot so served shall be of a size and shape to accommodate the necessary
length of tile fields at a safe distance from, and at a lower elevation
than, the proposed building(s) in accordance with Borough or State
regulations.
7. The proposed method of sanitary sewage disposal shall be in accordance
with the Borough's officially adopted Act 537 Sewage Facilities
Plan.
8. When the rules and regulations of the Pennsylvania Department of
Environmental Protection determines the necessity for an Act 537 Sewage
Facilities Plan Revision, the procedure set forth in those rules and
regulations shall be followed.
[Ord. 614, 12/29/1992, § 506; as amended by Ord.
680, 12/28/1998]

required by the Pennsylvania Department of Environmental Protection.
3. The sewage enforcement officer shall enter the results of the test
and all other information on five copies of the subdivision sewage
disposal report form and shall submit these with the preliminary plans;
provided, however, that where the approval of the proposed sanitary
sewage disposal facilities is otherwise required by the Pennsylvania
Department of Environmental Protection, two copies of the report of
investigation and approval may be submitted in lieu of the subdivision
sewage disposal report.
4. Where possible soil percolation tests shall be performed near the
site of the proposed onsite sanitary sewage disposal facilities and
spaced evenly throughout the property.
5. The results of the soil percolation tests shall be analyzed by the
Borough in relation to the physical characteristics of the tract being
subdivided and of the general area surrounding the tract.
[Ord. 614, 12/29/1992, § 507]
New subdivision and developments shall incorporate adequate
provisions for a reliable, safe and adequate water supply to support
intended uses within the capacity of available resources.
A. Each property shall be connected to the Borough's water system.
The distribution system shall be designed to furnish an adequate supply
of water to each lot with adequate main sizes, appurtenances and fire
hydrants located to meet the specifications of the Borough.
B. If for any reason an individual onsite water supply system(s) is
permitted each lot so served shall be of a size and shape to allow
safe location of such a system on each lot and wells shall be placed
uphill from sewage disposal systems and shall not be within 100 feet
of any part of the absorption (tile) field of any onsite sanitary
sewage disposal system nor within 50 feet from lakes, streams, ponds,
quarries, etc.
C. If for any reason an individual onsite water supply system(s) is
permitted, the subdivider shall provide at least one test well for
each 10 proposed dwelling units. Such wells should be drilled, cased
and grout sealed into bedrock at least 50 feet deep having a production
capacity of at least five gallons per minute of safe potable drinking
water as certified by State or Borough health officer.
D. If water is to be provided by means other than by private wells owned
and maintained by the individual owners of lots within the subdivision
or development, applicants shall present evidence to the Borough Council
that the subdivision or development is to be supplied by a certified
public utility or by a municipal corporation, authority or utility.
A copy of a certificate of public convenience from the Pennsylvania
Public Utility Commission or an application for such certificate or
a commitment or agreement to serve the area in question, whichever
is appropriate, shall be acceptable evidence.
[Ord. 614, 12/29/1992, § 508; as amended by Ord.
680, 12/28/1998]
1. General Principles for Storm Drainage Systems. Storm sewers, culverts,
endwalls, inlets and related installations and improvements shall
be provided in order to:
A. Permit unimpeded flow of natural watercourses.
B. Insure adequate drainage of all streets.
C. Intercept stormwater runoff along streets at intervals related to
the extent and grade of the area drained.
D. Provide positive drainage away from onsite sewage disposal facilities
and buildings.
E. Accommodate runoff so that there shall be no increase in rate of
stormwater peak discharge leaving the subdivision during or after
construction based on the design rainfall frequency established in
this chapter in accordance with § 22-508(1)(A).
F. Insure adequate drainage in intersections of driveways with streets.
2. Design of Storm Drainage Systems.
A. Complete stormwater calculations in accordance with the design standards and
Appendices of this chapter and all designs for drainage facilities shall be submitted to the Borough for review.
B. Where existing storm sewers are reasonably accessible and of adequate
capacity, subdivisions and land developments shall connect to the
existing storm sewers.
C. Stormwater runoff shall discharge to an existing watercourse with
defined bed and barriers or an existing storm drainage system. It
shall not be concentrated onto adjacent properties nor shall the velocity
of flow be increased beyond that existing prior to subdivision or
land development unless written approval is given by the adjacent
property owners to the proposed discharge of surface runoff and the
written agreements are approved by the Borough.
D. When storm drainage will be directed into an adjacent municipality
all provisions for accommodating such storm drainage shall be submitted
to the governing body of that municipality for review.
E. Stormwater runoff shall not be concentrated nor shall natural drainage
water be diverted as to overload or further overload, as the case
may be, existing drainage systems, create flooding or create the need
for additional drainage structures on other private or public lands
unless adequate provisions approved by the Borough and the owners
of the other affected private or public lands are made for taking
care of these conditions.
F. All provisions which shall be made to implement this chapter are
subject to approval by the Borough.
G. Where a subdivision or land development is traversed by or contains
a pond, lake, watercourse, drainageway, channel, storm drainage system
or stream there shall be provided a drainage easement that conforms
substantially with the line of such pond, lake, watercourse, drainageway,
channel, storm drainage system or stream of such width as will be
adequate to preserve the unimpeded flow of drainage and to provide
for widening, deepening, relocating, improving or protecting such
features or drainage facilities. Minimum easement width shall be 10
feet from each side of the watercourse, water body, stream, pond,
lake or drainage facility but the Borough may require a greater easement

B. General Design Considerations.
(1)
In the design of detention and retention facilities the tributary
watershed within the subdivision or land development in a fully developed
state and the tributary watershed outside the subdivision or land
development in its present condition. The Borough shall require developers
of upper portions of the watershed to also maintain zero increase
in runoff.
(2)
The number and location of detention facilities are subject
to the approval of the Borough.
(3)
For dry bottom water storage areas a method of carrying low
flow through the pond area shall be provided and the areas shall be
provided with a positive gravity outlet to a natural channel or storm
sewer of adequate capacity.
(4)
If percolation of runoff is considered as a method of runoff
abatement, percolation tests shall be taken at the site of proposed
detention facilities and the results submitted to the Borough for
review.
(5)
The storage duration resulting from the combination of storage
of water from the design storm and the design release rate shall be
approved by the Borough. Detention areas shall be designed so that
they return to normal condition within approximately 24 hours after
the termination of the storm unless the Borough Engineer finds that
downstream conditions may warrant other design criteria for stormwater
release. The Borough may require the fencing of water storage areas
when deemed necessary for the public safety.
(6)
Every stormwater storage area shall be provided with an emergency
spillway with its design based upon a one-hundred-year frequency rainfall.
The spillway shall either be placed in undisturbed earth or be of
concrete construction and shall be designed to function without attention.
(7)
The pipe spillway outletting from the stormwater storage area
into a subsurface piped drainage system shall be designed on the basis
of a rainfall frequency that is consistent with the requirements of
this chapter which shall be approved by the Borough. Stormwater runoff
velocities and quantities shall be consistent with the need to protect
the public health, safety and welfare and to prevent turbulent conditions
and erosion. Peak discharge shall be no greater than predicted for
predevelopment conditions.
(8)
Minimum grades for turf areas inside detention basins shall
be 1% and maximum side slopes of retention/detention basins shall
be 33% (three units horizontally to one unit vertically). Depending
upon the location and the intended use of the detention facilities
during nonfunctioning times, a side slope of less than 33% for one
or both slopes may be required by the Borough Council. Side slopes
shall be kept as close to the natural land contours as practical but
when a detention basin is to be maintained by a future residential
lot owner the maximum side slope shall be 25% (four units horizontally
to one unit vertically).
(9)
Paved surfaces that are to serve as stormwater storage areas
shall have minimum grades of 1/2% and shall be restricted to storage
depths of 1/2 feet maximum.

shall be provided. Design calculations to substantiate the effectiveness
of these aeration facilities shall be submitted with final engineering
plans. Agreements for the perpetual operation and maintenance of aeration
facilities shall be prepared to the satisfaction of the Borough.
(f)
In the event that the water surface of the pond is to be raised
for the purposes of storing water for irrigation or in anticipation
of the evapotranspiration demands of dry weather, the volume remaining
for storage of excess stormwater runoff shall still be sufficient
to contain the design year storm runoff.
C. Specific Design Considerations for Stormwater Detention Basins.
(1)
The design of stormwater detention basins shall be according
to the methods in the U.S. Department of Agriculture, Soil Conservation
Service Technical Release No. 55, "Urban Hydrology for Small Watersheds."
(a)
After installation of imperious cover, peak discharges from
the site shall not exceed the before construction peak discharge rate
from a two year, twenty-four-hour storm for all storms up to a ten-year,
twenty-five-hour storm. Peak discharges for any storms of greater
than ten-year frequency up to and including a one-hundred-year storm
shall not exceed the peak discharges from the site of such storms
before development, including twenty-five-, fifty- and one-hundred-year
storms.

Whenever a basin will be located in an area underlain by limestone,
a geological evaluation of the proposed location shall be conducted
to determine susceptibility to sinkhole formations. The design of
all facilities over limestone formations shall include measures to
prevent groundwater contamination and, where necessary, sinkhole formation.
Soils used for the construction of basins shall have low erodibility
factors ("K" factors). The Borough may require the installation of
an impermeable liner in detention basins.

3. Utility and Drainage Easements.
A. On July 8, 1970, the Pennsylvania Utility Commission issued an order
requiring all electric distribution lines to be installed underground
in residential developments of five or more family units. This also
applies to mobile home parks, apartment houses and row houses. In
compliance with these regulations and with the cooperation of local
utility companies the following procedure will be followed in reviewing
plans subject to underground electric service:
(1)
Upon filing a preliminary plan or an official sketch plan for
review the subdivider will forward a copy to the appropriate utility
company if the development would fall subject to the order. This would
apprise the utility company of the project status and indicate that
the subdivider would be contacting them in the near future.
(2)
Upon receipt and review of preliminary plans the subdivider
is directed to contact the utility company and secure an approval
of plans for underground electric system. Receipt of a letter from
the utility company indicating receipt of plans will be required prior
to Borough endorsement of any plan for recording. The responsibility
for securing this approval and coordinating the plan with the utility
company would be the subdivider's or his representative's.
B. Easements with a minimum width of 20 feet shall be provided for poles,
wires, conduits, storm and sanitary sewers, gas, water and heat mains
and/or other utility lines intended to service the abutting lots.

D. Subdividers and developers are urged to avail themselves of the services
provided by the various public utility companies in determining the
proper locations for utility easements.
E. Utility service for residential development not subject to the abovementioned
Pennsylvania Public Utility Commission's order is recommended
to be provided through the use of underground facilities in accord
with the standards and approval of the utility company having appropriate
jurisdiction.
F. The following guidelines shall be applied as needed in establishing
easements as part of erosion and sediment controls:
(1)
Nothing shall be permitted to be placed, planted, set or put
within the area of easement. The area should be kept as lawn.
(2)
Where a subdivision or land development is traversed by a watercourse,
there shall be provided a drainage easement or right-of-way conforming
substantially with the line of such watercourse and of such width
as will be adequate to preserve natural drainage but not less than
20 feet or as may be required or directed by the Department of Environmental
Protection. The owner shall properly grade and seed slopes and fence.
(3)
Where stormwater or surface water will be gathered within the
subdivision or land development and discharged or drained in volume
over lands within or beyond the boundaries of the subdivision or land
development, the applicant or owner shall reserve or obtain easements
over all lands affected thereby, which easements shall be adequate
for such discharge of drainage and for the carrying off of such water
and for the maintenance, repair and reconstruction of the same, including
the right of passage over and upon the same by vehicles, machinery
and other equipment for such purposes and which shall be of sufficient
width for such passage and work. The owner shall convey, free of charge
or cost, such easements to the Borough upon demand.

section shall serve as an executive summary.
B. The impact studies listed below shall be submitted to the Borough
in the following instances:
(1)
A residential subdivision or land development of 50 or more
lots and/or dwelling units.
(2)
A nonresidential subdivision of five or more lots.
(3)
A nonresidential land development containing 40,000 square feet
or more of gross floor area. Provided that the Borough Council reserves
the right to require impact studies for any subdivision or land development
when the Borough Council deems such a study necessary to adequately
review the impact of the subdivision or land development.
(a)
Utilities Impact Study. A study shall be prepared by a registered
professional engineer indicating the impact of the proposed development
on the existing sanitary sewer, water, solid waste and drainage systems
serving the Borough. Said impact analysis shall identify the existing
capacity of facilities which would serve the development, the prospects
of those facilities being able to provide service to it and any improvements
that might be required as a direct result of the proposed development.
Additionally, the study shall identify the likely ability of sanitary
sewer, water, solid waste and drainage systems to continue to provide
efficient and economic service to existing residents and businesses
within the Borough considering added service requirements of the proposed
development.
(b)
Recreation Impact Study. The study shall analyze the demand
for recreational facilities which the proposed development will generate
and determine whether adequate facilities exist or are planned or
proposed. As a minimum, the study shall include the following:
1)
A description of the projected age breakdown of the residents
of the proposed development.
2)
A description of any recreational facilities to be provided
by the developer.
3)
A description of existing municipal recreational facilities
and the impact of the proposed development on these facilities. Accepted
national standards for required recreation shall be used in the analysis.
4)
Discussion of potential for any recreational facilities to be
provided by the developer to compensate for any anticipated deficiencies
of the Borough's recreational facilities.
5)
A description of any contributions the developer plans to make
for Borough recreation to compensate for expected impacts.
(c)
Fiscal Impact Analysis. A fiscal impact analysis shall be prepared
identifying the likely impact of the development on the Borough and
School District's tax structure and expenditure patterns. Included
shall be a determination of the revenues to accrue to the Borough
and School District as a result of a proposed development as well
as an identification of the cost associated with delivering services
to the proposed development. The fiscal impact analysis shall deal
with the impact of the proposed development on the ability of the
Borough to deliver fire, police, administrative, public works and
utility services to the development and on the Borough's economy.
In order to prepare the analysis the applicant shall utilize a methodology
from "The New Guide to Fiscal Impact Analysis" (Rutgers Center for
Urban Policy Research, 1985, as modified from time to time), adapted
as appropriate and to the Borough's satisfaction. Particular
aspects of the Borough's service delivery capability to be analyzed
shall include:
1)
Public Works. This includes potential effects on the maintenance,
repair and upkeep of roads, signal systems, sanitary sewer, water
and drainage systems, open space and recreation areas or any other
applicable function. This study shall address projected cost increases
for the above-mentioned items in terms of administration, personnel,
equipment and materials.
2)
Administration. This includes time that would be required by
the Borough Council, Manager and other staff to process the application
and handle the project during construction as well as long-term administration
demands. This should include, but not be limited to, the handling
of plans, contracts, various legal instruments or agreements, permits,
special problems and escrow. Added demands on the code administration
staff also shall be projected.
3)
Fire and Emergency Services. The analysis shall incorporate
the development's impact on fire company capabilities including,
but not limited to, municipal water supply, pumping capacity, specialized
equipment and training requirements.
4)

development on existing Borough police personnel numbers, equipment,
vehicles and working space. The study shall include whatever facilities
or assistance the development will provide to handle emergencies,
criminal investigation, armed robbery or other security related problems.
(d)
Historic and Archeological Resources Impact Study. All historic
and archaeological resources which have been identified and/or inventoried
by the Borough, the Berks County Planning Commission and/or the Pennsylvania
Historical Museum Commission located within the tract shall be identified
and the impact on such resources detailed.
(e)
Environmental Impact Study. The study shall include the following
impacts:
1)
Habitats of threatened and endangered species of special concern
in Pennsylvania within the tract, as established by the Pennsylvania
Biological Survey and/or Pennsylvania Natural Diversity Inventory,
shall be identified and the impact on such resources detailed. If
such habitats exist on the tract the measures proposed to protect
the habitats shall be indicated.
2)
The suitability of the site for the intensity of use proposed
by the intensity of use proposed by the site's soils, slopes,
woodlands, wetlands, floodplains, aquifers, natural resources and
other natural features.
3)
The impact of the proposed use on the site's soils, slopes,
woodlands, wetlands, floodplains, natural resources and natural features,
the degree to which these are protected or destroyed, the tolerance
of the resources to development and any adverse environmental impacts.
4)
The impact of the proposal on the preservation of agriculture
and other land uses which are essential to public health and welfare.
(f)

a qualified hydrogeologist and consist of the following minimum considerations:
1)
A map showing the location of the site.
2)
A description of the geologic conditions on and around the site.
Site geology, including stratigraphy, structure and soils shall be
analyzed. Hydrogeology, including aquifer characteristics, groundwater
movement, local water use, aquifer yield and water quality shall be
analyzed. Groundwater impacts, availability of groundwater, well interference,
water quality and yield availability shall be analyzed.
3)
Should it be determined that the proposed use(s) would result
in a degradation of groundwater quality or eliminate the potential
groundwater use at nearby properties, the study shall present measures
that will be employed to prevent these adverse impacts.
[Ord. 614, 12/29/1992, § 510]
1. When maximal provision is to be made for the use of solar energy
by structures, in general, streets toward which buildings are to be
oriented should run in an east-west direction.
2. Section 504(1)(A) indicates that insofar as practical, side lot lines
shall be at right angles to straight street lines and radial to curved
street lines. The Borough may allow variation from this requirement
where provision is to be made for maximal use of solar energy, in
which case, side lot lines generally may run from due north to due
south or with slight variation east or west of this axis.
A. When lot lines will not be provided, consideration should be given
to orienting buildings to maximize solar access. Generally, buildings
should be located with their long axes running east to west, though
in some high density or townhouse developments a north-south orientation
for the long axes may be desirable.
B. Consideration should be given to locating structures and open spaces
such that buildings will not cast shadows on other buildings.
3. Consideration should be given to reserving solar easements within
lots for protection of solar access.
[Ord. 614, 12/29/1992, § 511]
