The following standards apply to new and substantially improved commercial, industrial and other nonresidential structures, in addition to the requirements in § 119-20A, Subdivision proposals, § 119-20B, Encroachments, and § 119-21, Anchoring of structures.
A. 
Within Zones A1-A30, AE and AH, and also Zone A if base flood elevation data are available, new construction and substantial improvements of any nonresidential structure, together with attendant utility and sanitary facilities, shall either:
(1) 
Have the lowest floor, including basement or cellar, elevated to or above the base flood elevation; or
(2) 
Be floodproofed so that the structure is watertight below the base flood level 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.
B. 
Within Zone AO, new construction and substantial improvements of nonresidential structures shall:
(1) 
Have the lowest floor (including basement) elevated above the highest adjacent grade at least as high as the depth number specified in feet on the community's FIRM (at least two feet if no depth number is specified); or
(2) 
Together with attendant utility and sanitary facilities, be completely floodproofed to that level to meet the floodproofing standard specified in Subsection A(2).
C. 
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 Subsection A(2), including the specific elevation (in relation to mean sea level) to which the structure is to be floodproofed.
D. 
Within Zones AH and AO, adequate drainage paths are required to guide floodwaters around the away from proposed structures on slopes.
E. 
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.

§ 119-26 Manufactured homes and recreational vehicles.

The following standards in addition to the standards in §§ 119-20, Construction standards, and 119-21, Anchoring of 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.
A. 
Recreational vehicles.
(1) 
Recreational vehicles placed on sites within Zones A1-A30, AE and AH shall either:
(a) 
Be on site fewer than 180 days;
(b) 
Be fully licensed and ready for highway use; or
(c) 
Meet the requirements for manufactured homes in Subsection B(3) and (4).
(2) 
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.
B. 
Manufactured homes.
(1) 
A manufactured home that is placed or substantially improved in Zones A1-A30, AE and AH that is on a site either outside of an existing manufactured home park or subdivision as herein defined; in a new manufactured home park or subdivision as herein defined; in an expansion to an existing manufactured home park or subdivision as herein defined; or in an existing manufactured home park or subdivision as herein defined on which a manufactured home has incurred substantial damage as the result of a flood; 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. Methods of anchoring may include, but are not limited to, use of over-the-top or frame ties to ground anchors.
(2) 
A manufactured home to be placed or substantially improved in Zones A1-A30, AE and AH in an existing manufactured home park or subdivision that is not to be placed on a site on which a manufactured home has incurred substantial damage shall be:
(a) 
Elevated in a manner such as required in Subsection B(1); or
(b) 
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 the lowest adjacent 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.
(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 the lowest adjacent 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.
(4) 
Within Zone AO, the floor shall be elevated above the highest adjacent grade at least as high as the depth number specified in the Flood Insurance Rate Map enumerated in § 119-6 (at least two feet if no depth number is specified). Elevation on piers consisting of dry stacked blocks is prohibited.

§ 119-27 Appeals Board.

A. 
The Zoning Board of Appeals as established by the Town of Clifton Park shall hear and decide appeals and requests for variances from the requirements of this chapter.
B. 
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 chapter.
C. 
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.
D. 
In passing upon such applications, the Zoning Board of Appeals shall consider all technical evaluations, all relevant factors, standards specified in other sections of this chapter and:
(1) 
The danger that materials may be swept onto other lands to the injury of others.
(2) 
The danger to life and property due to flooding or erosion damage.
(3) 
The susceptibility of the proposed facility and its contents to flood damage and the effect of such damage on the individual owner.
(4) 
The importance of the services provided by the proposed facility to the community.
(5) 
The necessity to the facility of a waterfront location, where applicable.
(6) 
The availability of alternative locations for the proposed use which are not subject to flooding or erosion damage.
(7) 
The compatibility of the proposed use with existing and anticipated development.
(8) 
The relationship of the proposed use to the Comprehensive Plan and floodplain management program of that area.
(9) 
The safety of access to the property in times of flood for ordinary and emergency vehicles.
(10) 
The costs to local governments and the dangers associated with conducting search and rescue operations during periods of flooding.
(11) 
The expected heights, velocity, duration, rate of rise and sediment transport of the floodwaters and the effects of wave action, if applicable, expected at the site.
(12) 
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.
E. 
Upon consideration of the factors of Subsection D 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 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.

§ 119-28 Conditions for variances.

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, provided that items in § 119-27D(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.
B. 
Variances may be issued for the repair or rehabilitation of historic structures upon determination that:
(1) 
The proposed repair or rehabilitation will not preclude the structure's continued designation as an historic structure.
(2) 
The variance is the minimum necessary to preserve the historic character and design of the structure.
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:
(1) 
The criteria of Subsections A, D, E and F of this section are met;
(2) 
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.
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 or extraordinary public expense or 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 of the signature of a community official that the cost of flood insurance will be commensurate with the increased risk resulting from lowest floor elevation.[1]
