Gianinette - Additional Flood Plain information.
c.
3-301. FLOODPLAI N OVERLAY REGULATIONS.
Specific Standards.
ln the Floodplain Overlay, where BFE data has been provided, the following provisions are required:
L. Residential Construction. New Construction and Substantial lmprovement of any residential structure shall
have the Lowest Floor (including Basement), elevated to l- foot above the BFE. A qualified professional
engineer, architect, or land surveyor shall submit a certification to the Floodplain Administrator' Nof
Applicabte - The Proposed Event Center is not Residential Construction.
2. Nonresidential Construction. With the exception of Critical Facilities, New Construction and Substantial
lmprovements of any commercial, industrial, or other nonresidential structure shall either have the Lowest
Floor (irrclurling Basement) elevated to at least 1- foot above the Base Flood level or together with attendant
utility and sanitary facilities, be designed so that below L foot above the Base Flood level the structure is
watertight with walls substantially impermeable to the passage of water and with structuralcomponents
having the capability of resisting hydrostatic and hydrodynamic loads and effects of buoyancy. A qualified
professional engineer or architect shall develop and/or review structural design, specifications, and plans for
the construction, and shall certify that the design and methods of construct¡on are in accordance with
accepted standards of practice as outlined in this subsection. A record of such certification that includes the
specific elevation (in relation to mean sea level)to which such structures are flood-proofed shall be provided
to and maintained by the Floodplain Administrator. ¡4s stated in July 13, 2018 "Amendment to
Ftood ptain Report" to Mr. Ernie Gianinetti letter, 3'd paragraph, "The event center's
minimum finished floor elevation is 6101.5 feet (one foot above the 100-year
FpE).,, The Event Center's minimum finished floor elevation is shown on both
project drawing's "Sife Ptan (C,7)" and Floodplain Specific Site PIan (C'1A) inside the-lines
where the event center rs proposed to be built. The Event Center's minimum
finished floor elevation of 6101.5 rs a/so specified in item a. for the "Top of bottom
floor,' in Section C of the FEMA Elevation Certificate, Signed and Sealed By Bruce D'
Lewis, Professional Engineer, on July, 13 2018-
3. Enclosures. New Construction and Substantial lmprovements, with 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 that are subject to flooding, shall be 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 qualified professional engineer or architect and meet or exceed
the following minimum criteria:
a. provide a min¡mum of 2 openings having a total net area of not less than 1 square inch
for every square foot of enclosed area subject to flooding;
b. The bottom of all openings shall be no higher than L foot above grade; and
c. Openings may be equipped with screens, louvers, valves, or other coverings or devices provided that
they permit the unrestricted entry and exit of floodwaters.

4.109. DEVELOPMENT IN E IOO-YEAR FLOODP LAIN.
c.Review Criteria.
A Floodplain Development Permit may be issued by the Director or designated Floodplain Administrator if it is
found that the application is in conformance with section 3-301, Floodplain Overlay Regulations, and upon
weighing the following relevant factors:
1" The danger to life anrJ property clrre to flooding nr erosion damage; Na danger ta life ar Property is
anticipated.
2. The susceptibility of the proposed facility and its contents to flood damage and the effect of such damage on
the individuatowner The proposed Event Center and its contents are not susceptible to
flood damage.
3. The danger that materials may be swept onto other lands to the injury of others; lt iS not antiCipated
that materials may be swept onto other lands to the iniury of others .
4. The compatibility of the proposed use with existing and anticipated development ; The proposed Use
is compatible with the existing and anticipated development.
5. The safety of access to the property in times of flood for ordinary and emergency vehicles; As shOwn on
the "Floodplain Specific Site plan", the 1ù0-year flood plain water should not exceed
77" in depth along any section of access road to the Event Center. Plus, the Event
Center should not be occupied during any periods of time when the flood water
covers fhe access road.
6. The costs of providing governmental services during and after flood conditions, including maintenance and
repair of streets and bridges , The access road to the Event Center will be maintained and
repaired from any flood damage by the property owner.
7. and public utilities and facilities such as sewer, gas, electrical, and water systems; The electric, water
and sewer utilities will be maintained and repaired from any flood damage by the
propefi owner.
8. The expected heights, velocity, duration, rate of rise, and sediment transport of the flood waters and the
effects of wave action, if applicable, expected at the site; No significant erosion or sediment is
anticipated.g. The necessity to the facility of a waterfront locat¡on, where applicable; Not applicable.
1-0. The availability of alternative locations, not subject to flooding or erosion damage, for the proposed use;
and Ihe proposed area is ideal for an Event Center due to the views, recreational
access, and proposed use (non residential),
1L. The relationship of the proposed use to the Comprehensive Plan for that area. The proposed Use of
the area is suitable as it enhances the currenf uses of the area and does not change
úhe use included under the Comprehensive Plan.
Nofe.' The proposed Event Center r.s desþned to be built one foot above the 100-year
flood plain elevation.
