in this chapter, the interpretation of the provisions of this chapter
is intended to be such that whenever the provisions contained herein
are at variance with applicable provisions of other provisions of
this code or of other lawfully adopted statutes, ordinances, rules

levee, dike, pile abutment, projection, excavation, channel, rectification,
culvert, building, fence, stockpile, refuses, fill, structure, or
matter in, along, across, or projecting into any channel, watercourse,
or designated floodplain district, which may impede, retard, or change

flow of the water might carry the same downstream to the damage of
life and property.

One-hundred-year flood - a flood that, on the average,
is likely to occur once every 100 years (i.e., that has a 1% chance
of occurring each year, although the flood may occur in any year).

addition, or other improvement of a structure, the cost of which equals
or exceeds 50% of the market value of the structure before the "start
of construction" of the improvement. This term includes structures
which have incurred "substantial damage," regardless of the actual
repair work performed. The term does not, however, include either:
| |
(1)
|
Any project for improvement of a structure to correct existing
violations of state or local health, sanitary, or safety code specifications
which have been identified by the local code enforcement official
and which are the minimum necessary to assure safe living conditions.
|
(2)
|
Any alteration of a "historic structure," provided that the
alteration will not preclude the structure's continued designation
as a "historic structure."

the strict application of the requirements, in accordance with the
terms of this section.
| |
3606.2 Standards for Review: Requests for variances to the strict
application of the elevation or floodproofing requirements of this
chapter may be granted by the Board of Supervisors in accordance with
the following standards:
| |
A.
|
No variance shall be granted for any construction, development
use or activity within any designated floodway district or area that
would cause any increase in the 100-year elevation.
|
B.
|
No variances shall be granted unless all structures proposed
thereby shall be designed and constructed so as to have the capability
of resisting the hydrostatic and hydrodynamic loads and pressures,
and the effects of buoyancy of the 100-year flood.

|
That there is good and sufficient cause for the variance.
|
(2)
|
That the failure to grant the variance will result in exceptional
hardship to the applicant.

or prohibited increased flood heights, additional threats to public
safety, extraordinary public expense; create nuisances; cause fraud
on or victimization of the public; or conflict with any other applicable
local or State ordinances and regulations.
|
E.
|
If granted, the variance shall involve only the least modification

achieve the objectives of this chapter.
|
3606.3 Notification: Whenever a code variance is granted, the
Board of Supervisors shall notify the applicant in writing that:

SECTION 3608.0 - WARNING AND DISCLAIMER OF LIABILITY.
| |
3608.1 Warning: 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 in rare occasions. Flood heights may be increased
by man-made or natural causes, such as ice jams and bridge openings
restricted by debris. The provisions of this chapter do not imply
that areas outside the designated floodplain districts, or that construction,
development or other land uses permitted within such district, will
be free from flooding or flood damages.
| |
3608.2 Disclaimer of Liability: This chapter shall not create
liability on the part of East Vincent Township, the Code Enforcement
Officer, the Township Engineer, or any other officer or employee thereof,
for any flood damages that may result from reliance on the provisions
of this chapter or on any administrative decision lawfully made hereunder.
| |
SECTION 3609.0 - STATE LAWS AND REGULATIONS, VALIDITY
AND CONTINUATION OF EXISTING REGULATIONS.
| |
3609.1 State Law and Regulations: In all matters that are regulated
by the laws of the Commonwealth of Pennsylvania or by regulations
of departments or agencies of the Commonwealth promulgated by authority
of law, such laws or regulations, as the case may be, shall control
where the requirements thereof are the same as or in excess of the
provisions of this chapter. The Code shall control in all cases where
the State requirements are not as strict as those contained in this
chapter.
| |
3609.2 Validity: The invalidity of any section or part of this
chapter shall not affect the remaining Sections.
| |
3609.3 Provisions to be Continuation of Existing Regulations:
The provisions of this chapter so far as they are the same as those
of ordinances and/or codes in force immediately prior to the enactment
of this chapter, are intended as a continuation of such ordinances
and codes and not as new enactments. The provisions of this chapter
shall not affect any act done or liability incurred, nor shall they
affect any suit or prosecution pending or to be instituted to enforce
any right or penalty or to punish any offense under the authority
of any of the repealed ordinances.
