What is the purpose of
Answer:
Article I Section C “It is the purpose of this ordinance to promote the public health, safety and general welfare and to minimize public and private losses due to flood conditions in specific areas by provisions designed to: (1) Protect human life and health; (2) Minimize expenditure of public money for costly flood control projects; (3) Minimize the need for rescue and relief efforts associated with flooding and generally undertaken at the expense of the general public; (4) Minimize prolonged business interruptions; (5) Minimize damage to public facilities and utilities such as water and gas mains, electric, telephone and sewer lines, streets and bridges located in floodplains; (6) Help maintain a stable tax base by providing for the sound use and development of flood-prone areas in such a manner as to minimize future flood blight areas; and (7) Insure that potential buyers are notified that property is in a flood area.”
What methods are available for reducing the
flood losses that occur in flood hazard areas? Answer:
Article I Section D “In order to accomplish its purposes, this ordinance uses the following methods: (1) Restrict or prohibit uses that are dangerous to health, safety or property in times of flood, or cause excessive increases in flood heights or velocities; (2) Require that uses vulnerable to floods, including facilities which serve such uses, be protected against flood damage at the time of initial construction; (3) Control the alteration of natural floodplains, stream channels, and natural protective barriers, which are involved in the accommodation of flood waters; (4) Control filling, grading, dredging and other development which may increase flood damage; (5) Prevent or regulate the construction of flood barriers which will unnaturally divert flood waters or which may increase flood hazards to other lands.
What are “special flood hazard areas”
(SFHAs), and how are they
identified? Answer:
Article 2 “…
Article 3
Section A
LANDS TO WHICH THIS ORDINANCE APPLIES “The ordinance shall apply to all areas of special flood
hazard with the jurisdiction of Article 3
Section B
BASIS FOR ESTABLISHING AREAS OF SPECIAL FLOOD
HAZARD “The areas of special flood hazard identified by the Federal
Emergency Management Agency on its Flood Hazard Boundary Map (FHBM), Community
Number 050467, dated Answer: Regardless of the type of structure, a permit is required; similarly, proposed land development (e.g. new subdivision) requires a permit. Conditional approval, in the form of a conditional permit, should be obtained from the Floodplain Administrator, before any work is done in the SFHA. Article 4, Section C(1) states: “Application for a development permit shall be presented to the Floodplain Administrator on forms furnished by him/her and may include, but not be limited to, plans in duplicate drawn to scale showing the location, dimensions, and elevation of proposed landscape alterations, existing and proposed structures, including the placement of manufactured homes, and the location of the foregoing in relation to areas of special flood hazard.”
Are there specific standards for placement
of manufactured homes in an SFHA? Answer:
“…all
manufactured homes to be placed within Zone A on a community’s FHBM or Answer:
In addition to general standards required of any structure in a
flood hazard area, Article 5, Section B(1) of White County Flood Damage
Prevention Ordinance states that – “new construction and substantial improvement
of any residential structure shall have the lowest floor (including basement)
elevated to or above the base flood elevation (BFE). A registered professional engineer,
architect, or land surveyor shall submit a certification to the Floodplain
Administrator that the standard of this subsection as proposed in Article 4,
Section C(1) a., is satisfied. Answer:
A(4): “All new construction or substantial improvements shall be constructed with electrical, heating, ventilation, plumbing, and air conditioning equipment and other service facilities that are designed and/or located so as to prevent water from entering or accumulating within the components during conditions of flooding.” A(5): “All new and replacement water supply systems shall be designed to minimize or eliminate infiltration of flood waters into the system;” A(6): “New and replacement sanitary sewage systems shall be designed to minimize or eliminate infiltration of flood waters into the system and discharge from the systems into flood waters; and, A(7): “On-site waste disposal systems shall be located to avoid impairment to them or contamination from them during flooding. Answer:
C(1): “All subdivision proposals including the placement of manufactured home parks and subdivisions shall be consistent with Article 1, Sections B, C, and D of this ordinance.” C(2): “All proposals for the development of subdivisions including the placement of manufactured home parks and subdivisions shall meet Development Permit requirements of Article 3, Section C; Article 4, Section C; and the provisions of Article 5 of this ordinance.” C(3): “Base flood elevation data shall be generated for the subdivision proposals and other proposed development including the placement of manufactured home parks and subdivisions which (are) greater than 50 lots or 5 acres, whichever is lesser, if not otherwise provided pursuant to Article 3, Section B or Article 4, Section B(8) of this ordinance.” C(4): “All subdivision proposals including the placement of manufactured home parks and subdivisions shall have adequate drainage provided to reduce exposure to flood hazards. C(5): “All subdivision proposals including the placement of manufactured home parks and subdivisions shall have public utilities and facilities such as sewer, gas, electrical and water systems located and constructed to minimize or eliminate flood damage.” Answer: Plans for proposed changes in an SFHA require prior approval from the Floodplain Administrator (Article 4, Section C(1)). Also, DO NOT, under
any circumstances make changes to a natural stream or other water body (e.g.
construct dam, build road with culvert, or re-route stream), or modify a natural
wetland area, without obtaining prior approval the U. S. Army Corps of
Engineers. Answer: “…new construction and substantial improvements of any commercial, industrial or other nonresidential structure shall either have the lowest floor (including basement) elevated to or above the base flood level or together with attendant utility and sanitary facilities, be designed so that below the base flood level the structure is watertight with walls substantially impermeable to the passage of water and with structural components having the capability of resisting hydrostatic and hydrodynamic loads and effects of buoyancy. A registered professional engineer or architect shall develop and/or review structural design, specifications, and methods of construction, and shall certify that the design and methods of construction are in accordance with accepted standards of practice as outlined in this subsection…” |
