purposes. In the proceeding before the Zoning Hearing Board, the burden
shall be upon the applicant to establish that the excluded uses and
conduct shall not be engaged in.
D. The provisions of this amendment are hereby declared to be severable
from the provisions of this chapter, and if any of the provisions
of this amendment to the chapter are found to be illegal or otherwise
unconstitutional, the provisions shall be severable from all other

Borough and all facilities and systems as listed below. The applicant
shall provide all of the information, data and studies needed to allow
the Borough Council and Planning Commission to reach conclusive evaluations
of the items listed below:
(1)
The compatibility of the proposed development with existing
and proposed land uses adjacent to the site in terms of:
(b)
Size, scale, bulk, general appearance and building materials.
(c)
The applicant shall submit architectural drawings for evaluation
of the proposed principal buildings, including building elevations
and colored renderings in comparison to photographs of existing buildings
adjacent to the site.
(2)
Evidence that the proposed conditional use meets the minimum standards specified for the particular use in Article
XVIII, Additional Requirements for Specific Uses, of this chapter.
(3)
The impact on the Borough transportation network and the ability
of adjacent streets and intersections to efficiently and safely move
the volume of traffic generated by the development.
(4)
Evidence that the Perkiomen Valley School District has been
advised of the proposed development's estimate of new pupils.
(5)
The impact on the Borough's community facilities, including
estimates of additional community facilities which will be needed
to serve the proposed conditional use. Community facilities include
but shall not be limited to sewage disposal facilities and systems,
solid waste disposal facilities and systems, water supply facilities
and systems, storm drainage systems and electrical utility facilities
and systems.

The ability of the Borough to provide police and fire protection
to the proposed conditional use.
(7)
The impact on the Borough's recreation facilities including
estimates of additional facilities which will be needed to serve the
conditional use.

A cost-revenue analysis which shall identify the net cost of
the proposed development to the Borough. The net cost shall be the
difference between the governmental expenditures required to serve
the proposed conditional use and the revenues that it will generate.

loss is anticipated and shall itemize the measurements used in the
evaluation.
C. Findings.

The Borough Council shall consider the recommendations of the
Borough Planning Commission before granting or denying tentative approval
of a development plan.
(2)
The Borough Council shall by official communication to the applicant
either:

chapter, as it may deem necessary to implement the purposes of the

as well as the purposes and objectives of this chapter.
Where, under this chapter, a permitted use is authorized pursuant
to the jurisdiction of the Zoning Hearing Board of the Borough of
Trappe, the Zoning Hearing Board is empowered to grant permission
for special exceptions, consistent with the public interest, in specifically
considering the following standards, which standards must be met,
where applicable, with the applicant having the burden of proof as
follows:
A. That the proposal includes adequate site design methods, such as
plant screening, tree preservations, setbacks and berming, as needed
to avoid significant negative impact on nearby uses.
B. That full consideration to the size, scope, extent and character
of the proposed use will be established by the applicant to assure
that the request is consistent with the plan for future land use in
the Borough of Trappe and consistent with the spirit, purpose and
intent of this chapter.
C. That the character and type of development as proposed would not
affect the character and type of development in the area surrounding
the location for which the request is made and that the proposed use
would be an appropriate use in the area and would not substantially
injure or detract from the use of the surrounding property or the
character of the neighborhood.
D. That the public interest or the need for the proposed use of change
would not be adversely affected, and the public health, safety, morals
and general welfare of the Borough would be protected.
E. That proposals to provide water service, sewage service and stormwater
management are feasible and follow professionally sound methods. However,
if such matters will be subject to professional review and approval
under a separate Borough ordinance, then the zoning approval may defer
to such other approval. The proposed change and use will be logical,
efficient and economical of the extension of public services and facilities
such as public water, sewers, police and fire protection and public
schools.
F. That the use will not create a significant hazard to the public health
and safety, such as fire, toxic or explosive hazards.
G. That the subdivision standards and requirements, where applicable,
can be met.
H. That the use will not create, exacerbate, or add to any traffic problem
or pose a safety issue directly or indirectly or add to traffic congestion.
The proposed location of the use will not have adverse affects upon
traffic, and there will be adequate access arrangements in order to
protect the roadways within the Borough for undue congestion and hazard.
I. That the natural features and processes characterizing the proposed
site and its surroundings shall not suffer degeneration, that the
management of storm waste, provision of water or sewer service, and
any other alterations to the sites predevelopment condition shall
be consistent with the Borough's goals, practices and plans in
those regards and that there will be no adverse environmental impact,
and the demand for water and energy for the proposed use shall be
minimized to the optimal extent.
J. The Zoning Hearing Board may impose such conditions, in addition
to those required, as are necessary to assure the intent of this chapter
is complied with, and which are reasonably necessary to safeguard
the health, safety, morals, and general welfare of the residents of
the Borough at large and the residents and owners of the property
adjacent to the area in which the proposed use is to be conducted.
The conditions are not limited to but may include the harmonious design
of buildings, aesthetics, hours of operation, lighting, number of
persons involved, noise, sanitation, safety, smoke and fume control,
stormwater control, traffic control, ingress and egress provisions,
open space and the minimizing of noxious, offensive or hazardous elements
