A local law for Flood Damage Prevention as authorized
by the New York State Constitution,
The Town Board of the Town of Hancock finds that the potential and/or actual damages from flooding and erosion may be a problem to the residents of the Town of Hancock 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. In order to minimize the threat of such damages and to achieve the purposes and objectives hereinafter set forth, this lo-cal law is adopted.
1.2 STATEMENT OF PURPOSE
It is the purpose of this local law to promote the public health, safety, and general welfare, and to minimize public and private losses due to flood conditions in specific areas by provisions designed to:
(1) 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;
(2) require that uses vulnerable to floods, including facilities which serve such uses, be protected against flood damage at the time of initial construction;
(3) control the alteration of natural floodplains, stream channels, and natural protective barriers which are involved in the accommodation of flood waters;
(4) control filling, grading, dredging and other development which may increase erosion or flood damages;
(5) regulate the construction of flood barriers which will unnaturally divert flood waters or which may increase flood hazards to other lands, and;
(6) qualify and maintain for participation in the National Flood Insurance Program.
The objectives of this local law are:
(l) to protect human life and health;
(2) to minimize expenditure of public money for costly flood control
(3) to minimize the need for rescue and relief efforts associated with flooding and generally undertaken at the expense of the general public;
(4) to minimize prolonged business interruptions;
(5) to minimize damage to public facilities and utilities such as water and gas mains, electric, telephone, sewer lines, streets and bridges located in areas of special flood hazard;
(6) 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;
(7) to provide that developers are notified that property is in an area of special flood hazard; and,
(8) to ensure that those who occupy the areas of special flood hazard assume responsibility for their actions.
Unless specifically defined below, words or phrases used in this local law shall be interpreted so as to give them the meaning they have in common usage and to give this local law its most reasonable application.

3.3 INTERPRETATION AND CONFLICT WITH OTHER LAWS
This Local Law 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.
In their interpretation and application, the provisions of this local law
shall be held to be minimum requirements, adopted for the promo¬tion of the
public health, safety, and welfare. Whenever the requirements of this local
law 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.
The invalidity of any section or provision of this local law shall not invalidate any other section or provision thereof.
3.5 PENALTIES FOR NON-COMPLIANCE
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 local law and any other applicable regulations. Any infraction of the provisions of this local law 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 local law or fails to comply with any of its requirements shall, upon conviction thereof, be fined no more than $250 or imprisoned for not more than l5 days or both. Each day of noncompliance shall be considered a separate offense. Nothing herein contained shall prevent the Town of Hancock from taking such other lawful action as necessary to prevent or remedy an infraction. Any structure found not compliant with the requirements of this local law for which the develop¬er and/or owner has not applied for and received an approved variance under Section 6.0 will be declared non-compliant and notifica¬tion sent to the Federal Emergency Management Agency.
3.6 WARNING AND DISCLAIMER OF LIABILITY
The degree of flood protection required by this local law 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 local law 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 local law shall not create liability on the part of the Town of Hancock, any officer or employee thereof, or the Federal Emergency Management Agency, for any flood damages that result from reliance on this local law or any administrative decision lawfully made there under.

(i) have the lowest floor, including basement or cellar, elevated to or above two feet above the base flood elevation; or
(ii) be floodproofed so that the structure is watertight below two feet above the base flood elevation, including attendant utility and sanitary facilities, with walls substantially impermeable to the passage of water. All structural components located below the base flood level must be capable of resisting hydrostatic and hydrodynamic loads and the effects of buoyancy.
(2) Within Zone AO, new construction and substantial improvements of non-residential structures shall:
(i) have the lowest floor (including basement) elevated above the highest adjacent grade at least as high as two feet above the depth number specified in feet on the community's FIRM (at least two feet if no depth number is specified), or
(ii) together with attendant utility and sanitary facilities, be completely floodproofed to that level to meet the floodproofing standard specified in sub-section 5.4(1)(ii)
(3) If the structure is to be floodproofed, a licensed professional engineer or architect shall develop and/or review structural design, specifications, and plans for construction. A Flood-proofing Certificate or other certification shall be provided to the Local Administrator that certifies the design and methods of construction are in accordance with accepted standards of practice for meeting the provisions of Section 5.4(1)(ii), including the specific elevation (in relation to mean sea level) to which the structure is to be floodproofed.
(4) Within Zones AH and AO, adequate drainage paths are required to guide flood waters around and away from proposed structures on slopes.
(5) Within Zone A, when no base flood elevation data are available, the lowest floor (including basement) shall be elevated at least three feet above the highest adjacent grade.
5.5 MANUFACTURED HOMES AND RECREATIONAL VEHICLES
The following standards in addition to the standards in Section 5.1, GENERAL STANDARDS, and Section 5.2, STANDARDS FOR ALL STRUCTURES apply, as indicated, in areas of special flood hazard to manufactured homes and to recreational vehicles which are located in areas of special flood hazard.
(1) Recreational vehicles placed on sites within Zones A1-A30, AE and AH shall either:
(i) be on site fewer than 180 consecutive days,
(ii) be fully licensed and ready for highway use, or
(iii) meet the requirements for manufactured homes in paragraphs 5.5(2), (3) and (4).
A recreational vehicle is ready for highway use if it is on its wheels or jacking system, is attached to the site only by quick disconnect type utilities and security devices and has no permanently attached additions.
(2) A manufactured home that is placed or substantially improved in Zones A1-A30, AE and AH shall be elevated on a permanent foundation such that the lowest floor is elevated to or above two feet above the base flood elevation and is securely anchored to an adequately anchored foundation system to resist flotation, collapse and lateral movement.
(3) Within Zone A, when no base flood elevation data are available, new and substantially improved manufactured homes shall be elevated such that the manufactured home chassis is supported by reinforced piers or other foundation elements of at least equivalent strength¬ that are no less than 36 inches in height above grade and are securely anchored to an adequately anchored foundation system to resist flotation, collapse or lateral movement.
(4) Within Zone AO, the floor shall be elevated above the highest
adjacent grade at least as high as the depth number specified on the Flood
Insurance Rate Map enumerated in Section 3.2 (at least two feet if no depth
number is specified).
5.6 CRITICAL FACILITIES
In order to prevent potential flood damage to certain facilities that
would result in serious danger
6.1 APPEALS BOARD
(l) The Planning Board as estab¬lished by the Town of Hancock shall hear and decide appeals and requests for variances from the requirements of this local law.
(2) The Planning Board shall hear and decide appeals when it is alleged there is an error in any requirement, decision, or determination made by the Local Administrator in the enforcement or administration of this local law.
(3) Those aggrieved by the decision of the Planning Board may appeal such decision to the Supreme Court pursuant to Article 78 of the Civil Practice Law and Rules.
(4) In passing upon such applications, the Planning Board, shall consider all technical evaluations, all relevant factors, standards specified in other sections of this local law and:
(i) the danger that materials may be swept onto other lands to the injury of others;
(ii) the danger to life and property due to flooding or erosion damage;
(iii) the susceptibility of the proposed facility and its contents to flood damage and the effect of such damage on the individual owner;
(iv) the importance of the services provided by the proposed facility to the community;
(v) the necessity to the facility of a waterfront location, where applicable;
(vi) the availability of alternative locations for the proposed use which are not subject to flooding or erosion damage;
(vii) the compatibility of the proposed use with existing and anticipated development;
(viii) the relationship of the proposed use to the comprehensive plan and floodplain management program of that area;
(ix) the safety of access to the property in times of flood for ordinary and emergency vehicles;
(x) the costs to local governments and the dangers associated with conducting search and rescue operations during periods of flooding;
(xi) the expected heights, velocity, duration, rate of rise and sediment transport of the flood waters and the effects of wave action, if applicable, expected at the site; and
(xii) the costs of providing governmental services during and after flood conditions, including search and rescue operations, maintenance and repair of public utilities and facilities such as sewer, gas, electrical, and water systems and streets and bridges.
(5) Upon consideration of the factors of Section 6.l(4) and the purposes of this local law, the Planning Board may attach such conditions to the granting of variances as it deems necessary to further the purposes of this local law.
(6) The Local Administrator shall maintain the records of all appeal actions including technical information and report any variances to the Federal Emergency Management Agency upon request.
6.2 CONDITIONS FOR VARIANCES
(l) Generally, variances may be issued for new construction and substantial improvements to be erected on a lot of one-half acre or less in size contiguous to and surrounded by lots with existing structures constructed below the base flood level, providing items (i-xii) in Section 6.l(4) have been fully considered. As the lot size increases beyond the one-half acre, the technical justification required for issuing the variance increases.
(2) Variances may be issued for the repair or rehabilitation of historic structures upon determination that:
(i) the proposed repair or rehabilitation will not preclude the structure's continued designation as a "Historic structure"; and
(ii) the variance is the minimum necessary to preserve the historic character and de-sign of the structure.
(3) 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:
(i) the criteria of subparagraphs l, 4, 5, and 6 of this Section are met; and
(ii) the structure or other development is protected by methods that minimize flood damages during the base flood and create no additional threat to public safety.
(4) Variances shall not be issued within any designated floodway if any increase in flood levels during the base flood discharge would result.
(5) Variances shall only be issued upon a determination that the variance is the minimum necessary, considering the flood hazard, to afford relief.
(6) Variances shall only be issued upon receiving written justification of:
(i) a showing of good and sufficient cause;
(ii) a determination that failure to grant the variance would result in exceptional hardship to the applicant; and
(iii) 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.
(7) 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:
(i) the issuance of a variance to construct a structure below the base flood level will result in increased premium rates for flood insurance up to amounts as high as $25 for $100 of insurance coverage; and
(ii) such construction below the base flood level increases risks to life and property.
Such notification shall be maintained with the record of all variance
actions as required in Section 4.4-8 of this Local Law.
