more than one foot at any location; or
(b) The Town of Queensbury 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 Queensbury 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 Queensbury 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 §
91-6, 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 Town of Queensbury 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 Queensbury 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 Queensbury for all costs related

A. Elevation. The following standards, in addition to the standards in §
91-14A, Subdivision proposals, and §
91-14B, Encroachments, and §
91-15, 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 §
91-6 (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 6-17-2002 by L.L.
No. 3-2002]
The following standards apply to new and substantially improved commercial, industrial and other nonresidential structures, in addition to the requirements in §
91-14A, Subdivision proposals, and §
91-14B, Encroachments, and §
91-15 Standards for all 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 one foot above the base flood elevation; or
(2) Be floodproofed so that the structure is watertight below
one foot above 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 one foot more than the depth
number specified in feet on the community's FIRM; or
(2) Together with attendant utility and sanitary facilities, be completely floodproofed to that level to meet the floodproofing standards 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 and 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.

No. 3-2002]
The following standards, in addition to the standards in §
91-14, General standards, and §
91-15, Standards for all 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 placed on sites within Zones A1-A30, AE and AH shall either be on site fewer than 180 consecutive days; be fully licensed and ready for highway use; or meet the requirements for manufactured homes in Subsections
B,
D and
E. 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. 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
one foot 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.
C. 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:
(1) Elevated in a manner such as required in Subsection
B; or
(2) 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.
D. 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.
E. Within Zone AO, the floor shall be elevated above the highest adjacent grade at least as high as one foot more than the depth number specified on the Flood Insurance Rate Map enumerated in §
91-6 (at least two feet if no depth number is specified). Elevation on piers consisting of dry stacked blocks is prohibited.
