Editor's Note: This local law also repealed former Ch. 87, Flood Damage Prevention, adopted 9-13-1993 by L.L. No. 3-1993; amended in its entirety 3-17-1997 by L.L. No. 1-1997.
The Mayor and the Board of Trustees of the Incorporated Village of Freeport finds that the potential and/or actual damages from flooding and erosion may be a problem to the residents of the Village of Freeport 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 purpose and objectives hereinafter set forth, this chapter is adopted.
Control the alteration of natural floodplains, stream channels and natural protection barriers which are involved in the accommodation of floodwaters.
Qualify for and maintain participation in the National Flood Insurance.
Help maintain a stable tax base by providing for sound use and development of areas of special flood hazard so as to minimize future blight areas.
Ensure that those who occupy the area of special flood hazard assume responsibility for their actions.
A designated AO, AH or VO Zone on a community's Flood Insurance Rate Map (FIRM) with a one-percent-or-greater annual chance of flooding to an average annual depth of one to three feet where a clearly defined channel does not exist, where the path of flooding is unpredictable and where velocity flow may be evident. Such flooding is characterized by ponding or sheet flow.
The land in the floodplain within a community subject to a one-percent-or-greater chance of flooding in any given year. This area may be designated as Zone A, AE, AH, AO, A1-A30, A99, V, VO, VE, or V1-V30. It is also commonly referred to as the base floodplain or one-hundred-year floodplain. For purposes of this chapter, the term "special flood hazard area (SFHA)" is synonymous in meaning with the phrase "area of special flood hazard."
An area of special flood hazard extending from offshore to the inland limit of a primary frontal dune along an open coast and any other area subject to high velocity wave action from storms or seismic sources. The area is designated on a FIRM as Zone V1-V30, VE, VO or V.
Adequately anchored so as not to impair the structural integrity of the building during a flood of up to the magnitude of the base flood. In the case of Zones A1-A30, AE, A, A99, AO, AH, B, C, X, or D, "elevated building" also includes a building elevated by means of fill or solid foundation perimeter walls with openings sufficient to facilitate the unimpeded movement of floodwaters.
The federal agency that administers the National Flood Insurance Program. This agency is commonly known as "FEMA."
The collapse or subsidence of land along the shore of a lake or other body of water as a result of erosion or undermining caused by waves or currents of water exceeding anticipated cyclical levels or suddenly caused by an unusually high water level in a natural body of water, accompanied by a severe storm, or by an unanticipated force of nature, such as a flash flood or an abnormal tidal surge, or by some similarly unusual and unforeseeable event which results in flooding as defined in (1) above.
An examination, evaluation, and determination of the flood hazards and, if appropriate, corresponding water surface elevations, or an examination, evaluation and determination of flood-related erosion hazards.
A use which cannot perform its intended purpose unless it is located or carried out in close proximity to water, such as a docking or port facility necessary for the loading or unloading of cargo or passengers, shipbuilding and ship repair facilities. The term does not include long-term storage, manufacturing, sales or service facilities.
The lowest floor of the lowest enclosed area (including basement or cellar). An unfinished or flood-resistant enclosure, usable solely for parking of vehicles, building access or storage in an area other than a basement area, is not considered a building's lowest floor, provided that such enclosure is not built so as to render the structure in violation of the applicable nonelevation design requirements of this chapter.
For the purposes of the National Flood Insurance Program, the National Geodetic Vertical Datum (NGVD) of 1929, the North American Vertical Datum of 1988 (NAVD 88), or other datum to which base flood elevations shown on a community's Flood Insurance Rate Map are referenced.

As corrected in 1988, a vertical control used as a reference for establishing varying elevations within the floodplain.
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 this chapter.
The date of permit issuance for new construction and substantial improvements to existing structures, provided that actual start of construction, repair, reconstruction, rehabilitation, addition placement, or other improvement is within 180 days after the date of issuance. The actual start of construction means the first placement of permanent construction of a building (including a manufactured home) on a site, such as the pouring of a slab or footings, installation of pilings or construction of columns. Permanent construction does not include land preparation (such as clearing, excavation, grading, or filling), or the installation of streets or walkways, or excavation for a basement, footings, piers or foundations, or the erection of temporary forms, or the installation of accessory buildings such as garages or sheds not occupied as dwelling units or not part of the main building. For a substantial improvement, the actual "start of construction" means the first alteration of any wall, ceiling, floor, or other structural part of a building, whether or not that alteration affects the external dimensions of the building.
Any alteration of an historic structure, provided that the alteration will not preclude the structure's continued designation as an historical structure.
This chapter shall apply to all areas of special flood hazard within the jurisdiction of the Incorporated Village of Freeport.

A scientific and engineering report entitled "Flood Insurance Study, Nassau County, New York (all jurisdictions)," dated September 11, 2009.
The above documents are hereby adopted and declared to be part of this chapter. The Flood Insurance Study and/or maps are on file at the Building Department of the Incorporated Village of Freeport at 46 North Ocean Avenue, Freeport, New York 11520.
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 $1,000 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 Incorporated Village of Freeport 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, contractor and/or owner has not applied for and received an approved variance under §§ 87-20 and 87-21 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 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 Incorporated Village of Freeport, any officer or employee thereof or the Federal Emergency Management Agency for any flood damage that results from reliance on this chapter or any administrative decision lawfully made thereunder.
The local administrator to administer shall be the Superintendent of Buildings and the Assistant Superintendent of Buildings, who shall implement this chapter by granting or denying floodplain development and/or building permits in accordance with its provisions.
Purpose. A floodplain development/building 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 § 87-6, without a valid floodplain development and/or building 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/building permit shall be accompanied by an application fee as prescribed by Chapter 86, Building Construction, of this Code. A fee for a certificate of compliance and/or certificate of occupancy will also be due at the time of application.
The proposed elevation, in relation to mean sea level, of the lowest floor (including basements, cellars or garages) of any new or substantially improved structures 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 local administrator the as-built elevation, certified by a licensed professional engineer or surveyor. Upon completion of the project, an elevation certificate must be submitted, on a form approved by FEMA, prior to the issuance of a certificate of compliance or certificate of occupancy.
A certificate from a licensed professional engineer or architect that any utility floodproofing will meet the criteria in § 87-16D.
A certificate from a licensed professional engineer or architect that any nonresidential floodproofed structure will meet the floodproofmg criteria in, § 87-16R.
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 segment of the waterway. The applicant must submit any maps, computations or other material required by the Federal Emergency Management Agency (FEMA) to revise the documents enumerated in § 87-6, 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 segment of the waterway will be maintained.
In Zones V1-V30 and VE, and also Zone V if base flood elevation are 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.

Review subdivision and other proposed 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 §§ 87-15 through 87-16.
Determine whether any proposed development in an area of special flood hazard may result in physical damage to any other property. The local administrator may require the applicant to submit additional technical analysis 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 §§ 87-15 through 87-16, 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.
Determine that all necessary permits have been received from those governmental agencies from which approval is required by state, county or federal law.
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 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 federal, state or other source, including data developed pursuant to § 87-13F as criteria for requiring that new construction, substantial improvements or other proposed development meet the requirements of this chapter.
When base flood elevation data are not available, the local 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 purpose of this chapter.
Notify adjacent communities and the New York State Department of Environmental Conservation prior to permitting any alteration or relocation of a watercourse, and submit evidence of such notification to the Regional Director, Region II, Federal Emergency Management Agency.
The local administrator shall, 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 floodproofmg 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 certification 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).

New construction and substantial improvements shall be elevated on pilings, columns or shear walls such that the bottom of the lowest horizontal structural member supporting the lowest elevated floor (excluding columns, piles, diagonal bracing attached to the piles or columns, grade beams, pile caps, and other members designed to either withstand storm action or break away without imparting damaging loads to the structure) is elevated to or above two feet above base flood elevation so as not to impede the flow of water.
Any owner who has applied for a permit to construct or elevate a structure on a property located in the FEMA designated flood hazard area must enter into a nonconversion agreement with the Village of Freeport.
Such agreement shall be signed by the owner prior to the issuance of any building permits. This agreement shall be recorded by the owner with the Nassau County Clerk's office.
With this agreement, the owner shall agree that all construction below the allowable lowest floor will meet all requirements of the National Flood Insurance Program; shall be in compliance with all local, county, state, and federal laws rules and regulations; and will allow upon consent inspection by the Department of Buildings to verify such conditions continue to exist.
Structural designs shall consider the effects of wind and water loads acting simultaneously during the base flood on all building components.
The structural design shall be adequate to resist water forces that would occur during a base flood. Horizontal water loads considered shall include inertial and drag forces of waves, current drag forces, and impact forces from waterborne debris. Dynamic uplift loads shall also be considered if bulkheads, walls or other natural or man-made flow obstructions could cause wave runoff beyond the elevation of the base flood.
Buildings shall be designed and constructed to resist the forces due to wind pressures. Wind forces on the superstructure include windward and leeward forces on vertical walls, uplift on the roof, internal forces when openings allow wind to enter the house and upward force on the underside of the house when exposed. In design, the wind should be assumed to blow potentially from any lateral direction relative to the house.
Wind loading values shall be those required by BOCA 160.0, Wind Loads (ASCE-1995).
The piling or column foundations and structure attached thereto shall be adequately anchored to resist flotation, collapse or lateral movement due to the effects of wind and water pressures acting simultaneously on all building components. Foundations must be designed to transfer safely to the underlying soil all loads due to wind, water dead load, live load, and other loads (including uplift due to wind and water).
Spread footings and fill material shall not be used for structural support of a new building or substantial improvements of an existing structure.
Soil-bearing tests must be submitted to the local administrator at the time of application. The number of borings will be determined by the scope of the project.
The design ratio of pile spacing to pile diameter shall not be less than 8:1 for individual piles (This shall not apply to pile clusters located below the design grade.). The maximum center-to-center spacing of wood piles shall not be more than 12 feet on center under load-bearing sills, beams, or girders.
The minimum acceptable sizes for timber piles are a tip diameter of eight inches for round timber piles and eight by eight inches for square timber piles. All wood piles must be treated in accordance with requirements of EPEE-C3 to minimize decay and damage from fungus.
Diagonal bracing between piles, consisting of two-inch-by-eight-inch (minimum) members bolted to the piles, shall be limited in location to below the lowest supporting structural member and above the stable soil elevation, and aligned in the vertical plane along pile rows perpendicular to the shoreline. Galvanized steel rods (minimum diameter 1/2 inch) or cable-type bracing is permitted in any place.
Knee braces, which stiffen both the upper portion of a pile and the beam-to-pile connection, may be used along pile rows perpendicular and parallel to the shoreline. Knee braces shall be two-by-eight lumber bolted to the sides of the pile/beam, or four-by-four-or-larger braces framed into the pile/beam. Bolting shall consist of two five-eighths-inch galvanized steel bolts (each end) for two-by-eight members, or one five-eighths-inch lag bolt (each end) for square members. Knee braces shall not extend more than three feet below the elevation of the base flood.
Masonry piers or poured-in-place concrete piers shall be internally reinforced to resist vertical and lateral loads, and be connected with a movement-resisting connection to a pile cap or pile shaft.
Connectors and fasteners. Galvanized metal connectors, wood connectors, or bolts or size and number adequate for the calculated loads must be used to connect adjoining components of a structure. Toe nailing as a principal method of connection is not permitted. All metal connectors and fasteners used in exposed locations shall be steel, hot-dipped galvanized after fabrication. Connectors in protected interior locations shall be fabricated from galvanized sheet.
Beam-to-pile connections. The primary floor beams or girders shall span the supports in the direction parallel to the flow of potential floodwater and wave action and shall be fastened to the columns or pilings by bolting, with or without cover plates. Concrete members shall be connected by reinforcement, if cast in place, or (of precast) shall be securely connected by bolting and welding. If sills, beams, or girders are attached to wood piling at a notch, a minimum of two five-eighths-inch galvanized steel bolts or two hot-dipped galvanized straps 3/16 inch by four inches by 18 inches each bolted with two one-half-inch lag bolts per beam member shall be used. Notching of pile tops shall be the minimum sufficient to provide ledge support for beam members without unduly weakening pile connections. Piling shall not be notched so that the cross section is reduced below 50%.
Wood two-by-four-inch (minimum) connectors or metal joist anchors shall be used to tie floor joists to floor beams/girders. These should be installed on alternate floor joists, at a minimum. Cross bridging of all floor joists shall be provided. Such cross bridging may be one-by-three-inch members, placed eight feet on-center maximum, or solid bridging of same depth as joist at same spacing.
Plywood should be used for subflooring and attic flooring to provide good tortional resistance in the horizontal plane of the structure. The plywood should not be less than 3/4 inch total thickness, and should be exterior grade and fastened to beams or joists with 8d annular or spiral thread galvanized nails. Such fastening shall be supplemented by the application of waterproof industrial adhesive applied to all bearing surfaces.
Exterior wall connections. All bottom plates shall have any required breaks under a wall stud or an anchor bolt. Approved anchors will be used to secure rafters or joists and top and bottom plates to studs in exterior and bearing walls to form a continuous tie. Continuous fifteen-thirty-seconds-inch-or-thicker plywood sheathing overlapping the top wall plate and continuing down to the sill, beam, or girder may be used to provide the continuous tie. If the sheets of plywood are not vertically continuous, then two-by-four nailer blocking shall be provided at all horizontal joints. In lieu of the plywood, galvanized steel rods of one-half-inch diameter or galvanized steel straps not less than one inch wide by 1/16 inch thick may be used to connect from the top wall plate to the sill, beam or girder. Washers with a minimum diameter of three inches shall be used at each end of the one-half-inch round rods. These anchors shall be installed no more than two feet from each corner rod, no more than four feet on center.
All ceiling joists or rafters shall be installed in such a manner that the joists provide continuous tie across the rafters. Ceiling joists and rafters shall be securely fastened at their intersections. A metal or wood connector shall be used at alternate ceiling joist/rafter connections to the wall top plate.
Plywood, or other wood material, when used as roof sheathing, shall not be less than 15/32 inch of thickness, and shall be of exterior sheathing grade or equivalent. All attaching devices for sheathing and roof coverings shall be galvanized or be of other suitable corrosion-resistant material.
All corners, gable ends, and roof overhangs exceeding six inches shall be reinforced by the application of waterproof industrial adhesive applied to all bearing surfaces of any plywood sheet used in the sheathing of such corner, gable end, or roof overhang.
In addition, roofs should be sloped as steeply as practicable to reduce uplift pressures, and special care should be used in securing ridges, hips, valleys, eaves, vents, chimneys, and other points of discontinuity in the roofing surface.
Protection of openings. All exterior glass panels, windows, and doors shall be designed, detailed, and constructed to withstand loads due to the design wind speed of 75 mph. Connections for these elements must be designed to transfer safely the design loads to the supporting structure. Panel widths of multiple panel sliding glass doors shall not exceed three feet.
The elevated portion of the building and supporting foundation system will not be subject to collapse, displacement, or other structural damage due to the effects of wind and water loads acting simultaneously on all building components (structural and nonstructural). Water loading values used shall be those associated with the base flood. Wind loading values shall be those required by the Building Code.
Have the lowest floor, including basement or cellar, elevated to minimum of four feet above the base flood elevation or two feet above the New York State freeboard requirement, whichever is greater.
Together with attendant utility and sanitary facilities, be completely floodproofed to that level to meet the floodproofmg standard specified in § 87-16D.
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 § 87-16R(1)(a), including the specific elevation (in relation to mean sea level) to which the structure is to be floodproofed.
In Zones V1-V30, VE, and also Zone V if base flood elevations are available, new construction and substantial improvements of any nonresidential structure, together with attendant utility and sanitary facilities, shall have the bottom of lowest member of the lowest floor elevated to or above two feet above the base flood elevation. Floodproofing of structures is not an allowable alternative to elevating the lowest floor to two feet above the base flood elevation in Zones V1-V30, VE, and V.
Meet the requirements for manufactured homes in Subsections S(2) and (3) below.
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 two feet 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 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. Elevation on piers consisting of dry stacked blocked 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 § 87-6 (at least two feet if no depth number is specified). Elevation on piers consisting of dry stacked blocks is prohibited.

The Zoning Board of Appeals 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 section.
Those aggrieved by the decision of the Zoning Board of Appeals may appeal such decision to the Supreme Court, pursuant to Article 78 of the Civil Practice Law and Rules.
Upon consideration of the factors of § 87-20D and the purpose of this chapter, the Zoning Board of Appeals may attach such conditions to the granting of variances as it deems necessary to further the purpose of this chapter.
The local administrator shall maintain the records of all appeals actions, including technical information, and report any variances to the Federal Emergency Management Agency upon request.
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 elevation, providing items in § 87-20D(1) through (12) have been fully considered. As the lot size increases beyond the 1/2 acre, the technical justification required for issuing the variance increases.
Variances shall only be issued upon determination that the variance is the minimum necessary, considering the flood hazard, to afford relief.
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 such lowest floor elevation. Such notice shall be a required condition of the variance and shall be incorporated as a term of the development/building permit.
