Editor's Note: This local law also repealed former Ch.
133, Flood Damage Prevention, adopted 9-25-1995 by L.L. No. 6-1995.
The Town Board of the Town of Wappinger finds that the potential
and/or actual damages from flooding and erosion may be a problem to
the residents of the Town of Wappinger and that such damages may include
destruction or loss of private and public housing, damage to public
facilities, both publicly and privately owned, and injury to and loss
of human life. This chapter is adopted in order to minimize the threat
of such damages and to achieve the purposes and objectives hereinafter
set forth.
It is the purpose of this chapter to promote the public health,
safety, and general welfare, and to minimize public and private losses
due to flood conditions in specific flood-prone areas by adopting
provisions and regulations designed to:
A.
Regulate uses which are dangerous to health, safety and property
due to water or erosion hazards, or which result in damaging increases
in erosion or in flood heights or velocities;
B.
Require that uses vulnerable to floods, including facilities which
serve such uses, be protected against flood damage at the time of
initial construction;
C.
Control the alteration of natural floodplains, stream channels, and
natural protective barriers which are involved in the accommodation
of floodwaters;
D.
Control filling, grading, dredging and other development which may
increase erosion or flood damages;
E.
Regulate the construction of flood barriers which will unnaturally
divert floodwaters or which may increase flood hazards to other lands;
and
F.
Qualify for and maintain participation in the National Flood Insurance
Program.
The objectives of this chapter are:
A.
To protect human life and health;
B.
To minimize expenditure of public money for costly flood control
projects;
C.
To minimize the need for rescue and relief efforts associated with
flooding and generally undertaken at the expense of the general public;
D.
To minimize prolonged business interruptions;
E.
To minimize damage to public facilities and utilities such as water
and gas mains, electric, telephone and sewer lines, streets and bridges
located in areas of special flood hazard;
F.
To help maintain a stable tax base by providing for the sound use
and development of areas of special flood hazard so as to minimize
future flood blight areas;
G.
To provide that developers are notified that property is in an area
of special flood hazard; and
H.
To ensure that those who occupy the areas of special flood hazard
assume responsibility for their actions.
A.
Unless specifically defined below, words or phrases used in this
chapter shall be interpreted so as to give them the meaning they have
in common usage and to give this chapter its most reasonable application.

B.
The above documents are hereby adopted and declared to be a part
of this chapter. The Flood Insurance Study and/or maps are on file
at the office of the Town Clerk, Town of Wappinger, Town Hall, 20
Middlebush Road, Wappingers Falls, New York 12590.
A.
This chapter includes all revisions to the National Flood Insurance
Program through October 27, 1997, and shall supersede all previous
laws adopted for the purpose of flood damage prevention.
B.
In their interpretation and application, the provisions of this chapter
shall be held to be minimum requirements, adopted for the promotion
of the public health, safety, and welfare.
C.
Whenever the requirements of this chapter are at variance with the
requirements of any other lawfully adopted rules, regulations, or
ordinances, the most restrictive, or that imposing the higher standards,
shall govern.
No structure in an area of special flood hazard shall hereafter be constructed, located, extended, converted, or altered and no land shall be excavated or filled without full compliance with the terms of this chapter and any other applicable regulations. Any infraction of the provisions of this chapter by failure to comply with any of its requirements, including infractions of conditions and safeguards established in connection with conditions of the permit, shall constitute a violation. Any person who violates this chapter or fails to comply with any of its requirements shall, upon conviction thereof, be fined in the amount set forth in Chapter 122, Article V, § 122-20N of the Town of Wappinger Code or imprisoned for not more than 15 days, or both. Each day of noncompliance shall be considered a separate offense. Nothing herein contained shall prevent the Town of Wappinger from taking such other lawful action as necessary to prevent or remedy an infraction. Any structure found not compliant with the requirements of this chapter for which the developer and/or owner has not applied for and received an approved variance under §§ 133-20 and 133-21 will be declared noncompliant and notification sent to the Federal Emergency Management Agency.
The degree of flood protection required by this chapter is considered
reasonable for regulatory purposes and is based on scientific and
engineering considerations. Larger floods can and will occur on rare
occasions. Flood heights may be increased by man-made or natural causes.
This chapter does not imply that land outside the area of special
flood hazards or uses permitted within such areas will be free from
flooding or flood damages. This chapter shall not create liability
on the part of the Town of Wappinger, any officer or employee thereof,
or the Federal Emergency Management Agency, for any flood damages
that result from reliance on this chapter or any administrative decision
lawfully made thereunder.
The Code Enforcement Officer or the Zoning Administrator are
hereby appointed local administrator to administer and implement this
chapter by granting or denying floodplain development permits in accordance
with its provisions.
A.
Purpose. A floodplain development permit is hereby established for all construction and other development to be undertaken in areas of special flood hazard in this community for the purpose of protecting its citizens from increased flood hazards and insuring that new development is constructed in a manner that minimizes its exposure to flooding. It shall be unlawful to undertake any development in an area of special flood hazard, as shown on the Flood Insurance Rate Map enumerated in § 133-6, without a valid floodplain development permit. Application for a permit shall be made on forms furnished by the Code Enforcement Officer or Zoning Administrator and may include, but not be limited to plans, in duplicate, drawn to scale and showing the nature, location, dimensions, and elevations of the area in question; existing or proposed structures, fill, storage of materials, drainage facilities, and the location of the foregoing.
B.
Fees. All applications for a floodplain development permit shall be accompanied by an application fee as set forth in Chapter 122, Article IV, § 122-16F(1) of the Town of Wappinger Code. In addition, the applicant shall be responsible for reimbursing the Town of Wappinger for any additional costs necessary for review, inspection and approval of this project. The Code Enforcement Officer or Zoning Administrator shall require the applicant to fund and maintain an escrow account in accordance with Chapter 122, Article IV, § 122-16F(2) of the Town of Wappinger Code, to cover these additional costs.
[Amended 8-26-2013 by L.L. No. 12-2013]
The applicant shall provide the following information as appropriate;
additional information may be required on the permit application form:
A.
The proposed elevation, in relation to mean sea level, of the lowest
floor (including basement or cellar) of any new or substantially improved
structure to be located in Zones A1-A30, AE or AH, or Zone A if base
flood elevation data are available. Upon completion of the lowest
floor, the permittee shall submit to the Code Enforcement Officer
or Zoning Administrator the as-built elevation, certified by a licensed
professional engineer or surveyor.
B.
The proposed elevation, in relation to mean sea level, to which any
new or substantially improved nonresidential structure will be floodproofed.
Upon completion of the floodproofed portion of the structure, the
permittee shall submit to the Code Enforcement Officer or Zoning Administrator
the as-built floodproofed elevation, certified by a professional engineer
or surveyor.
C.
A certificate from a licensed professional engineer or architect that any utility floodproofing will meet the criteria in § 133-15C, Utilities.
D.
A certificate from a licensed professional engineer or architect that any nonresidential floodproofed structure will meet the floodproofing criteria in § 133-17, Nonresidential structures.
E.
A description of the extent to which any watercourse will be altered or relocated as a result of proposed development. Computations by a licensed professional engineer must be submitted that demonstrate that the altered or relocated segment will provide equal or greater conveyance than the original stream segment. The applicant must submit any maps, computations or other material required by the Federal Emergency Management Agency (FEMA) to revise the documents enumerated in § 133-6, when notified by the Code Enforcement Officer or Zoning Administrator, and must pay any fees or other costs assessed by FEMA for this purpose. The applicant must also provide assurances that the conveyance capacity of the altered or relocated stream segment will be maintained.
F.
A technical analysis, by a licensed professional engineer, if required
by the Code Enforcement Officer or Zoning Administrator, which shows
whether proposed development to be located in an area of special flood
hazard may result in physical damage to any other property.
G.
In Zone A, when no base flood elevation data are available from other
sources, base flood elevation data shall be provided by the permit
applicant for subdivision proposals and other proposed developments
(including proposals for manufactured home and recreational vehicle
parks and subdivisions) that are greater than either 50 lots or five
acres.
Duties of the Code Enforcement Officer or Zoning Administrator
shall include, but not be limited to the following:
A.
Permit application review. The Code Enforcement Officer or Zoning
Administrator shall conduct the following permit application review
before issuing a floodplain development permit:
(1)
Review all applications for completeness, particularly with the requirements of § 133-12, Application for permit, and for compliance with the provisions and standards of this chapter.
(2)
Review subdivision and other proposed new development, including manufactured home parks, to determine whether proposed building sites will be reasonably safe from flooding. If a proposed building site is located in an area of special flood hazard, all new construction and substantial improvements shall meet the applicable standards of §§ 133-14 through 133-18 and, in particular, § 133-14A, Subdivision proposals.
(3)
Determine whether any proposed development in an area of special flood hazard may result in physical damage to any other property (e.g., stream bank erosion and increased flood velocities). The Code Enforcement Officer or Zoning Administrator may require the applicant to submit additional technical analyses and data necessary to complete the determination. If the proposed development may result in physical damage to any other property or fails to meet the requirements of §§ 133-14 through 133-18, regarding general standards, no permit shall be issued. The applicant may revise the application to include measures that mitigate or eliminate the adverse effects and resubmit the application.
(4)
Determine that all necessary permits have been received from those
governmental agencies from which approval is required by state or
federal law.
B.
Use of other flood data.
(1)
When the Federal Emergency Management Agency has designated areas of special flood hazard on the community's Flood Insurance Rate Map (FIRM) but has neither produced water surface elevation data (these areas are designated Zone A or V on the FIRM) nor identified a floodway, the Code Enforcement Officer or Zoning Administrator shall obtain, review and reasonably utilize any base flood elevation and floodway data available from a federal, state or other source, including data developed pursuant to § 133-12G, as criteria for requiring that new construction, substantial improvements or other proposed development meet the requirements of this chapter.
(2)
When base flood elevation data are not available, the Code Enforcement
Officer or Zoning Administrator may use flood information from any
other authoritative source, such as historical data, to establish
flood elevations within the areas of special flood hazard, for the
purposes of this chapter.
C.
Alteration of watercourses.
(1)
Notification to adjacent communities and the New York State Department
of Environmental Conservation prior to permitting any alteration or
relocation of a watercourse, and submittal of evidence of such notification
to the Regional Administrator, Region II, Federal Emergency Management
Agency.
(2)
Determine that the permit holder has provided for maintenance within
the altered or relocated portion of said watercourse so that the flood-carrying
capacity is not diminished.
D.
Construction stage.
(1)
In Zones A1-A30, AE and AH, and also Zone A if base flood elevation
data are available, upon placement of the lowest floor or completion
of floodproofing of a new or substantially improved structure, obtain
from the permit holder a certification of the as-built elevation of
the lowest floor or floodproofed elevation, in relation to mean sea
level. The certificate shall be prepared by or under the direct supervision
of a licensed land surveyor or professional engineer and certified
by same. For manufactured homes, the permit holder shall submit the
certificate of elevation upon placement of the structure on the site.
A certificate of elevation must also be submitted for a recreational
vehicle if it remains on a site for 180 consecutive days or longer
(unless it is fully licensed and ready for highway use).
(2)
Any further work undertaken prior to submission and approval of the
certification shall be at the permit holder's risk. The Code
Enforcement Officer or Zoning Administrator shall review all data
submitted. Deficiencies detected shall be cause to issue a stop-work
order for the project unless immediately corrected.
E.
Inspections. The Code Enforcement Officer or Zoning Administrator
and/or the developer's engineer or architect shall make periodic
inspections at appropriate times throughout the period of construction
in order to monitor compliance with permit conditions and enable said
inspector to certify, if requested, that the development is in compliance
with the requirements of the floodplain development permit and/or
any variance provisions.
F.
Stop-work orders.
(1)
The Code Enforcement Officer or Zoning Administrator shall issue, or cause to be issued, a stop-work order for any floodplain development found ongoing without a development permit. Disregard of a stop-work order shall subject the violator to the penalties described in § 133-8 of this chapter.
(2)
The Code Enforcement Officer or Zoning Administrator shall issue, or cause to be issued, a stop-work order for any floodplain development found noncompliant with the provisions of this chapter and/or the conditions of the development permit. Disregard of a stop-work order shall subject the violator to the penalties described in § 133-8 of this chapter.
G.
Certificate of compliance.
(1)
In areas of special flood hazard, as determined by documents enumerated in § 133-6, it shall be unlawful to occupy or to permit the use or occupancy of any building or premises, or both, or part thereof hereafter created, erected, changed, converted or wholly or partly altered or enlarged in its use or structure until a certificate of compliance has been issued by the Code Enforcement Officer or Zoning Administrator stating that the building or land conforms to the requirements of this chapter.
(2)
A certificate of compliance shall be issued by the Code Enforcement
Officer or Zoning Administrator upon satisfactory completion of all
development in areas of special flood hazard.
H.
Information to be retained. The Code Enforcement Officer or Zoning
Administrator shall retain and make available for inspection, copies
of the following:
(1)
Floodplain development permits and certificates of compliance;
(2)

Upon consideration of the factors of § 133-20D and the purposes of this chapter, the Zoning Board of Appeals may attach such conditions to the granting of variances as it deems necessary to further the purposes of this chapter.
F.
The Code Enforcement Officer or Zoning Administrator shall maintain
the records of all appeal actions, including technical information,
and report any variances to the Federal Emergency Management Agency
upon request.
A.
Generally, variances may be issued for new construction and substantial improvements to be erected on a lot of 1/2 acre or less in size contiguous to and surrounded by lots with existing structures constructed below the base flood level, providing items in § 133-20D have been fully considered. As the lot size increases beyond the 1/2 acre, the technical justification required for issuing the variance increases.
B.
Variances may be issued for the repair or rehabilitation of historic
structures upon determination that:
C.
Variances may be issued by a community for new construction and substantial
improvements and for other development necessary for the conduct of
a functionally dependent use, provided that:
D.
Variances shall not be issued within any designated floodway if any
increase in flood levels during the base flood discharge would result.
E.
Variances shall only be issued upon a determination that the variance
is the minimum necessary, considering the flood hazard, to afford
relief.
F.
Variances shall only be issued upon receiving written justification
of:
(1)
A showing of good and sufficient cause;
(2)
A determination that failure to grant the variance would result in
exceptional hardship to the applicant; and
(3)
A determination that the granting of a variance will not result in
increased flood heights, additional threats to public safety, extraordinary
public expense, create nuisances, cause fraud on or victimization
of the public or conflict with existing local laws or ordinances.
G.
Any applicant to whom a variance is granted for a building with the
lowest floor below the base flood elevation shall be given written
notice over the signature of a community official that:
This chapter will be enforced by the Code Enforcement Officer,
Zoning Administrator, Fire Inspector or any police agency having jurisdiction
within the Town of Wappinger.
