The Town Board of the Town of Henrietta finds that the potential and/or actual damages from flooding and erosion may be a problem to the residents of the Town of Henrietta 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 chapter is adopted.
A structure with at least 5l% of its actual cash value, excluding land value, above ground.
The channel of a river or other watercourse and the adjacent land areas that must be reserved in order to discharge the base flood without cumulatively increasing the water surface elevation more than a designated height as determined by the Federal Emergency Management Agency in a Flood Insurance Study or by other agencies as provided in § 125-12B of this chapter.
This chapter shall apply to all areas of special flood hazard within the jurisdiction of the Town of Henrietta, Monroe County.
Flood Insurance Rate Map (single panel) Nos. 36055C-0329G, 36055C-0333G, 36055C-0334G, 36055C-0336G, 36055C-0337G, 36055C-0338G, 36055C-0339G, 36055C-0341G, 36055C-0342G, 36055C-0343G, 36055C-0344G, 36055C-0351G, 36055C-0352G, 36055C-0353G, 36055C-0354G, 36055C-0356G, 36055C-0358G, 36055C-0361G, 36055C-0362G, 36055C-0363G, 36055C-0364G, whose effective date is August 28, 2008.
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 Town of Henrietta, Department of Engineering/Planning, 475 Calkins Road, Henrietta, New York, 14467.
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 no more than $250 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 Henrietta 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 §§ 125-18 and 125-19 will be declared noncompliant, and notification shall be 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 areas of special flood hazard 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 Henrietta, 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.
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 ensuring 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 § 125-6, without a valid floodplain development permit. Application for a permit shall be made on forms furnished by the local 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.
Fees. All applications for a floodplain development permit shall be accompanied by an application fee as established by the Town Board of the Town of Henrietta. In addition, the applicant shall be responsible for reimbursing the Town of Henrietta for any additional costs necessary for review, inspection and approval of the project. The local administrator may require a deposit of no more than $500 to cover these additional costs.
The proposed elevation, in relation to mean sea level, of the bottom of the lowest structural member of the lowest floor (excluding pilings and columns) of any new or substantially improved structure to be located in Zone V1-V30 or VE, or Zone V if base flood elevation data is available. Upon completion of the lowest floor, the permittee shall submit to the local administrator the as-built elevation, certified by a licensed professional engineer or surveyor.
A certificate from a licensed professional engineer or architect that any utility floodproofing will meet the criteria in § 125-14C, Utilities.
A certificate from a licensed professional engineer or architect that any nonresidential floodproofed structure will meet the floodproofing criteria in § 125-16, Nonresidential structures.
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 § 125-6, when notified by the local 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.
In Zones V1-V30 and VE, and also Zone V if base flood elevation data is available, designs and specifications, certified by a licensed professional engineer or architect, for any breakaway walls in a proposed structure with design strengths in excess of 20 pounds per square foot.
In Zones V1-V30 and VE, and also Zone V if base flood elevation data is available, for all new and substantial improvements to structures, floodplain development permit applications shall be accompanied by design plans and specifications, prepared in sufficient detail to enable independent review of the foundation support and connection components. Said plans and specifications shall be developed or reviewed by a licensed professional engineer or architect and shall be accompanied by a statement, bearing the signature of the architect or engineer, certifying that the design and methods of construction to be used are in accordance with accepted standards of practice and with all applicable provisions of this chapter.
Review all applications for completeness, particularly with the requirements of § 125-11C, Application for a permit, and for compliance with the provisions and standards of this chapter.
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 §§ 125-13 through 125-17, general construction standards, and in particular, § 125-13A, Subdivision proposals.
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 local 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 applicable requirements of §§ 125-13 through 125-17, general construction 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.
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 local 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 § 125-11C(7), as criteria for requiring that new construction, substantial improvements or other proposed development meets the requirements of this chapter.
In Zones V1-V30 and VE, and also Zone V if base flood elevation data is available, upon placement of the lowest floor of a new or substantially improved structure, the permit holder shall submit to the local administrator a certificate of elevation, in relation to mean sea level, of the bottom of the lowest structural member of the lowest floor (excluding pilings and columns). 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. An elevation certificate must also be submitted for a recreational vehicle if it remains on a site 180 consecutive days or longer (unless it is fully licensed and ready for highway use).
The local 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 § 125-8 of this chapter.
The local 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 § 125-8 of this chapter.
In areas of special flood hazard, as determined by documents enumerated in § 125-6, 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 local administrator stating that the building or land conforms to the requirements of this chapter.
Issuance of the certificate shall be based upon the inspections conducted as prescribed in § 125-12E, Inspections, and/or any certified elevations, hydraulic data, floodproofing, anchoring requirements or encroachment analyses which may have been required as a condition of the approved permit.
Notices required under § 125-12C, Alteration of watercourses.
The Town of Henrietta agrees to apply to the Federal Emergency Management Agency (FEMA) for a conditional FIRM revision, FEMA approval is received and the applicant provides all necessary data, analyses and mapping and reimburses the Town of Henrietta for all fees and other costs in relation to the application. The applicant must also provide all data, analyses and mapping and reimburse the Town of Henrietta for all costs related to the final map revision.

The applicant must also provide all data, analyses and mapping and reimburse the Town of Henrietta for all costs related to the final map revisions.
Within Zones V1-V30 and VE, and also within Zone V if base flood elevation is available, new construction and substantial improvements shall have the space below the lowest floor either free from obstruction or constructed with nonsupporting breakaway walls, open-wood lattice-work or insect screening intended to collapse under wind and water loads without causing collapse, displacement, or other structural damage to the elevated portion of the building or supporting foundation system. The enclosed space below the lowest floor shall be used only for parking vehicles, building access or storage. Use of this space for human habitation is expressly prohibited. The construction of stairs, stairwells and elevator shafts is subject to the design requirements for breakaway walls.
Within Zone AO, new and substantially improved structures shall 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 Flood Insurance Rate Map enumerated in § 125-6 (at least two feet if no depth number is specified).
Together with attendant utility and sanitary facilities, be completely floodproofed to that level to meet the floodproofing standard specified in § 125-16A(2).
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 floodproofing 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 § 125-16A(2), including the specific elevation (in relation to mean sea level) to which the structure is to be floodproofed.
A manufactured home that is placed or substantially improved in Zones A1-A30, AE, AH, V1-V30, V, and VE shall be elevated on a permanent foundation such that the lowest floor is elevated to or above the base flood elevation and is securely anchored to an adequately anchored foundation system to resist flotation, collapse and lateral movement. Elevation on piers consisting of dry stacked blocks is prohibited.
Within Zone A or V, when no base flood elevation data is 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. Elevation on piers consisting of dry stacked blocks is prohibited.
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 § 125-6 (at least two feet if no depth number is specified).
The Zoning Board of Appeals as established by the Town of Henrietta shall hear and decide appeals and requests for variances from the requirements of this chapter.
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, provided that the items in § 125-18D(4) through  have been fully considered. As the lot size increases beyond the 1/2 acre, the technical justification required for issuing the variance increases.
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 the cost of flood insurance will be commensurate with the increased risk resulting from the lowest floor elevation. Such notification shall be maintained with the record of all variance actions as required in § 125-12H of this chapter.
