[Ord. 94, 6/8/1988, § 1400; as amended by Ord.
2014-11, 6/17/2014, Art. I]
1. The purpose of these provisions is to prevent the loss of property
and life, the creation of health and safety hazards, the disruption
of commerce and governmental services, the extraordinary and unnecessary
expenditure of public funds for flood protection and relief, and the
impairment of the tax base by:
A. Regulating uses, activities and development which, acting alone or
in combination with other existing or future uses, activities and
development, will cause increases in flood heights, velocities and
frequencies.
B. Restricting or prohibiting certain uses, activities and development
from locating within areas subject to flooding.
C. Requiring all those uses, activities and developments that do occur
in flood-prone areas to be protected and/or floodproofed against flooding
and flood damage.
D. Protecting individuals from buying lands and structures which are
unsuited for intended purposes because of flood hazards.
[Ord. 94, 6/8/1988, § 1401; as amended by Ord.
2014-11, 6/17/2014, Art. I]
These provisions shall apply to all lands within the Township
and shown as being located within the boundaries of the designated
Floodplain Conservation District which is considered as an overlay
to and part of the Official Zoning Map.
[Ord. 94, 6/8/1988, § 1402; as amended by Ord.
2014-11, 6/17/2014, Art. I]
No structure or land shall hereafter be used and no structure shall be located, relocated, constructed, reconstructed, enlarged or structurally altered except in full compliance with the terms and provisions of this chapter, the Township Floodplain Ordinance [Chapter
8] and any other applicable ordinances and regulations which apply to uses within the jurisdiction of this chapter.
[Ord. 94, 6/8/1988, § 1403; as amended by Ord.
2014-11, 6/17/2014, Art. I]
The degree of flood protection sought by the provisions of this
chapter is considered reasonable for regulatory purposes and is based
on acceptable engineering methods of study. Larger floods may occur
on rare occasions. Flood heights may be increased by man-made or natural
causes, such as dams, ice jams or bridge openings restricted by debris.
This chapter does not imply that areas outside the Floodplain Conservation
District, or that land uses permitted within such district will be
free from flooding or flood damages. This chapter shall not create
liability on the part of the Township or any officer or employee thereof
for any flood damages that result from reliance on this chapter or
any administrative decision lawfully made thereunder.
[Ord. 94, 6/8/1988, § 1404; as amended by Ord.
153, 5/3/1994, § 1; by Ord. 2014-11, 6/17/2014, Art. I;
and by Ord. 2015-3, 3/16/2015, Art. II]
1. Description of District.
A. The Floodplain Conservation District shall include the following:
(1)
Any areas of Solebury Township, classified as special flood
hazard areas (SFHAs) in the Flood Insurance Study (FIS) and the accompanying
Flood Insurance Rate Maps (FIRMS) dated March 16, 2015, and issued
by the Federal Emergency Management Agency (FEMA) or the most recent
revision thereof, including all digital data developed as part of
the Flood Insurance Study.
(2)
For areas abutting streams and watercourses where the base flood
elevation (one-percent annual chance flood) has not been delineated
by the Flood Insurance Study, the applicant shall submit a floodplain
identification study. The study, prepared by a registered professional
engineer expert in the preparation of hydrologic and hydraulic studies,
shall be used to delineate the base flood elevation. The floodplain
study shall be subject to the review and approval of the Township.
All areas inundated by the base flood shall be included in the Floodplain
Area.
[Amended by Ord. 2017-7, 8/15/2017]
B. The Floodplain Conservation District is delineated for purposes of
this chapter using the criterion that a certain area must be capable
of carrying the waters of the base flood without increasing the water
surface elevation of that area.
[Amended by Ord. 2017-7, 8/15/2017]
C. Overlay Concept.
(1)
The Floodplain Conservation District described above shall be
an overlay to the existing underlying districts as shown on the Zoning
Map; and, as such, the provisions for the Floodplain Conservation
District shall serve as a supplement to the underlying district provisions.
(2)
Where there is conflict between the provisions or requirements
for the Floodplain Conservation District and those of any underlying
district, the more restrictive provisions shall apply.
(3)
In the event any provision concerning the Floodplain Conservation
District is declared inapplicable as a result of any legislative or
administrative actions or judicial discretion, the basic underlying
district provision shall remain applicable.
[Ord. 94, 6/8/1988, § 1405; as amended by Ord.
2014-11, 6/17/2014, Art. I]

by Ord. 178, 6/15/1999, § IV.1; and by Ord. 2014-11, 6/17/2014,
Art. I]
The delineation of the Floodplain Conservation District may be revised by the Board of Supervisors where natural or man-made changes have occurred and/or more detailed studies are conducted or undertaken by the U.S. Army Corps of Engineers, the Delaware River Basin Commission, or other qualified agency or individual. However, prior to any such change, approval must be obtained from the Federal Emergency Management Agency (FEMA) for those flood districts as described in §
27-2105, Subsection 1(A)(1).
[Ord. 94, 6/8/1988, § 1407; as amended by Ord.

to the injury of others.
C. The
proposed water supply and sanitation systems and the ability of these
systems to prevent disease, contamination and unsanitary conditions.
D. The
susceptibility of the proposed facility and its contents to flood
damage and the effect of such damage on the individual owners.
E. The
importance of the services provided by the proposed facility to the
community.
F. The
requirements of the facility for a waterfront location.
G. The
availability of alternative locations not subject to flooding for
the proposed use.
H. The
compatibility of the proposed use with existing development and development
anticipated in the foreseeable future.
I. The
relationship of the proposed use to the Comprehensive Plan and floodplain
management program for the area.

M. Special
exception, variances and/or conditional uses shall only be issued
after the Zoning Hearing Board (in the case of a special exception
or variance) or the Board of Supervisors (in the case of a conditional
use) has determined that the granting of such will not result in:
(1)
Any increase in the base flood elevation.
[Amended by Ord. 2017-7, 8/15/2017]
(2)
Additional threats to public safety.
(3)
Extraordinary public expense.
(5)
Fraud or victimization of the public.
