The following standards apply to new development, including new and substantially improved structures, in the areas of special flood hazard shown on the Flood Insurance Rate Map designated in § 85-6, Basis for establishing areas of special flood hazard.
A. 
Subdivision proposals. The following standards apply to all new subdivision proposals and other proposed development in areas of special flood hazard (including proposals for manufactured home and recreational vehicle parks and subdivisions):
(1) 
Proposals shall be consistent with the need to minimize flood damage.
(2) 
Public utilities and facilities such as sewer, gas, electrical and water systems shall be located and constructed so as to minimize flood damage.
(3) 
Adequate drainage shall be provided to reduce exposure to flood damage.
B. 
Encroachments.

Within Zones A1-A30 and AE, on streams without a regulatory floodway, no new construction, substantial improvements or other development (including fill) shall be permitted unless:
(a) 
The applicant demonstrates that the cumulative effect of the proposed development, when combined with all other existing and anticipated development, will not increase the water surface elevation of the base flood more than one foot at any location; or
(b) 
The Village of Victor 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 Village of Victor for all fees and other costs in relation to the application. The applicant must also provide all data, analyses and mapping and reimburse the Village of Victor for all costs related to the final map revision.
(2) 
On streams with a regulatory floodway, as shown on the Flood Boundary and Floodway Map or the Flood Insurance Rate Map adopted in § 85-6, Basis for establishing areas of special flood hazard, no new construction, substantial improvements or other development in the floodway (including fill) shall be permitted unless:
(a) 
A technical evaluation by a licensed professional engineer shows that such an encroachment shall not result in any increase in flood levels during occurrence of the base flood; or
(b) 
The Village of Victor agrees to apply to the Federal Emergency Management Agency (FEMA) for a conditional FIRM and floodway revision, FEMA approval is received and the applicant provides all necessary data, analyses and mapping and reimburses the Village of Victor for all fees and other costs in relation to the application. The applicant must also provide all data, analyses and mapping and reimburse the Village of Victor for all costs related to the final map revisions.
A. 
Anchoring. New structures and substantial improvement to structures in areas of special flood hazard shall be anchored to prevent flotation, collapse or lateral movement during the base flood. This requirement is in addition to applicable state and local anchoring requirements for resisting wind forces.
B. 
Construction materials and methods.
(1) 
New construction and substantial improvements to structures shall be constructed with materials and utility equipment resistant to flood damage.
(2) 
New construction and substantial improvements to structures shall be constructed using methods and practices that minimize flood damage.
(3) 
Parking and storage areas.
(a) 
For enclosed areas below the lowest floor of a structure within Zones A1-A30, AE or AH, and also Zone A if base flood elevation data are available, new and substantially improved structures shall have fully enclosed areas below the lowest floor that are usable solely for parking of vehicles, building access or storage in an area other than a basement and which are subject to flooding designed to automatically equalize hydrostatic flood forces on exterior walls by allowing for the entry and exit of floodwaters. Designs for meeting this requirement must either be certified by a licensed professional engineer or architect or meet or exceed the following minimum criteria:
[1] 
A minimum of two openings having a total net area of not less than one square inch for every square foot of enclosed area subject to flooding shall be provided; and
[2] 
The bottom of all such openings shall be no higher than one foot above the lowest adjacent finished grade.
(b) 
Openings may be equipped with louvers, valves, screens or other coverings or devices provided that they permit the automatic entry and exit of floodwaters. Enclosed areas subgrade on all sides are considered basements and are not permitted.
C. 
Utilities.
(1) 
Machinery and equipment servicing a building must either be elevated to or above the base flood level or designed to prevent water from entering or accumulating within the components during a flood. This includes heating, ventilating and air-conditioning equipment; hot-water heaters; appliances; elevator lift machinery; and electrical junction and circuit breaker boxes. When located below the base flood elevation, a professional engineer's or architect's certification of the design is required.
(2) 
New and replacement water supply systems shall be designed to minimize or eliminate the infiltration of floodwaters into the system.
(3) 
New and replacement sanitary sewage systems shall be designed to minimize or eliminate infiltration of floodwaters. Sanitary sewer and storm drainage systems for buildings that have openings below the base flood elevation shall be provided with automatic backflow valves or other automatic backflow devices that are installed in each discharge line passing through a building's exterior wall.
(4) 
On-site waste disposal systems shall be located to avoid impairment to them or contamination from them during flooding.

A. 
Elevation. The following standards, in addition to the standards in § 85-14A, Subdivision proposals, and § 85-14B, Encroachments, and § 85-15, Standards for all structures, apply to structures located in areas of special flood hazard as indicated.
(1) 
Within Zones A1-A30, AE and AH, and also Zone A if base flood elevation data are available, new construction and substantial improvements shall have the lowest floor (including basement) elevated to or above one foot above the base flood level.
(2) 
Within Zone A, when no base flood elevation data are available, new and substantially improved structures shall have the lowest floor (including basement) elevated at least three feet above the highest adjacent grade.
(3) 
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 one foot more than the depth number, specified in feet on the community's Flood Insurance Rate Map, enumerated in § 85-6 (at least two feet if no depth number is specified).
(4) 
Within Zones AH and AO, adequate drainage paths are required to guide floodwaters around and away from proposed structures on slopes.
[Amended 4-19-2004 by L.L. No. 6-2004]
