[Amended 10-11-2016 by L.L. No. 3-2016]
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 § 82-6 of this chapter.
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) 
Enclosed areas below lowest floor.
(a) 
For enclosed areas below the lowest floor of a structure within Zones A1-A30, AE, AO or A, 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; and
[2] 
The bottom of all such openings 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 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) 
New and replacement electrical equipment, heating, ventilating, air-conditioning, plumbing connections, and other service equipment shall be located at least two feet above the base flood elevation, or at least three feet above the highest adjacent grade in a Zone A without an available base flood elevation, or be designed to prevent water from entering and accumulating within the components during a flood and to resist hydrostatic and hydrodynamic loads and stresses. Electrical wiring and outlets, switches, junction boxes and panels shall be elevated or designed to prevent water from entering and accumulating within the components unless they conform to the appropriate provisions of the electrical part of the Building Code of New York State or the Residential Code of New York State for location of such items in wet locations;
(2) 
New and replacement water supply systems shall be designed to minimize or eliminate 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; and on-site waste disposal systems shall be located to avoid impairment to them or contamination from them during flooding.

All new subdivision and other proposed development in areas of special flood hazard, including proposals for manufactured home and recreational vehicle parks and. subdivisions, shall be consistent with the need to minimize flood damage;
(2) 
All subdivision proposals shall have public utilities and facilities, such as sewer, gas, electrical and water systems, located and constructed to minimize flood damage;
(3) 
All subdivision proposals shall have adequate drainage provided to reduce exposure to flood damage; and
(4) 
Base flood elevation data shall be provided by the permit applicant for subdivision proposals and other proposed developments (including proposals for manufactured home and recreational vehicle parks and subdivisions) greater than either 50 lots or five acres.
E. 
Encroachments.
(1) 
All proposed development in riverine areas where no flood elevation data is available (unnumbered A Zones) shall be reviewed as set forth in § 82-15A(3), Permit review, to determine the effects of the encroachment on the flood-carrying capacity of the stream. The local administrator may require submission of additional technical analyses and data necessary to complete the determination.
(2) 
In all areas of special flood hazard in which base flood elevation data is available pursuant to § 82-15B or Subsection D(4) of this section and no floodway has been determined, the cumulative effects of any proposed development, when combined with all other existing and anticipated development, shall not increase the water surface elevation of the base flood more than one foot at any point.
(3) 
In all areas of special flood hazard where floodway data is provided or available pursuant to § 82-15B, the requirements of § 82-18, Floodways, shall apply, except as provided in Subsection E(4) of this section.
(4) 
Notwithstanding any other provisions of this chapter, certain development in Zones A1-30, AE and AH may be permitted to increase the water surface elevation of the base flood (e.g., dams, levees, etc.), provided that the Town of Woodstock endorses application to the Federal Emergency Management Agency (FEMA), the permit applicant provides all necessary data and analyses and pays all fees, and FEMA approval is received.
(5) 
The local administrator shall require within Zones AH and AO adequate drainage paths around structures on slopes, to guide floodwaters around and away from proposed structures.

[Amended 10-11-2016 by L.L. No. 3-2016]
A. 
Located within areas of special flood hazard are areas designated as floodways (see definition, Article II). The floodway is an extremely hazardous area due to high-velocity floodwaters carrying debris and posing additional threats from potential erosion forces. When floodway data is available for a particular site as provided by § 82-6 or, when applicable, § 82-15B, all encroachments, including fill, new construction, substantial improvements, and other development, are prohibited within the limits of the floodway unless a technical evaluation demonstrates that such encroachments shall not result in any increase in flood levels during the occurrence of the base flood discharge.
B. 
The Town of Woodstock 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 Town of Woodstock 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 Woodstock for all costs related to the final map revisions.
C. 
In Zones Al -A30, AE and AH, and also Zone A if base flood elevation data are available, if any development is found to increase or decrease base flood elevations, the Town of Woodstock shall, as soon as practicable, but not later than six months after the date such information becomes available, notify FEMA and the New York State Department of Environmental Conservation of the changes by submitting technical or scientific data in accordance with standard engineering practice.
