Editor's Note: This ordinance also repealed former Ch. 422,
Floodplain Management, adopted 3-6-1989, as amended.
A.
Certain areas of the Town of Madison, Maine, are subject to periodic
flooding, causing serious damages to properties within these areas.
Relief is available in the form of federally subsidized flood insurance
as authorized by the National Flood Insurance Act of 1968.
B.
Therefore, the Town of Madison, Maine, has chosen to become a participating
community in the National Flood Insurance Program, and agrees to comply
with the requirements of the National Flood Insurance Act of 1968
(P.L. 90-488, as amended) as delineated in the attached Floodplain
Management chapter.
C.
It is the intent of the Town of Madison, Maine, to require the recognition
and evaluation of flood hazards in all official actions relating to
land use in the floodplain areas having special flood hazards.
D.
The Town of Madison has the legal authority to adopt land use and
control measures to reduce future flood losses pursuant to 30-A M.R.S.A.
§§ 3001 through 3007, 4352, 4401 through 4407, and
38 M.R.S.A. § 440.
A.
The National Flood Insurance Program, established in the aforesaid
Act, provides that areas of the Town of Madison having a special flood
hazard be identified by the Federal Emergency Management Agency and
that floodplain management measures be applied in such flood hazard
areas. This chapter establishes a flood hazard development permit
system and review procedure for development activities in the designated
flood hazard areas of the Town of Madison, Maine.
B.
The areas of special flood hazard, Zones A and AE, for the Town of
Madison, Maine, identified by the Federal Emergency Management Agency
in a report entitled "Flood Insurance Study - Madison, Maine" dated
July 3, 1995, with accompanying Flood Insurance Rate Map, dated July
3, 1995, are hereby adopted by reference and declared to be a part
of this chapter.
Before any construction or other development (as defined in § 422-14), including the placement of manufactured homes, begins within any areas of special flood hazard established in § 422-2, a flood hazard development permit shall be obtained from the Code Enforcement Officer. This permit shall be in addition to any other building permits which may be required pursuant to the codes and chapters of the Town of Madison, Maine.
A.
The application for a flood hazard development permit shall be submitted
to the Code Enforcement Officer and shall include:
(1)
The name, address, and phone number of the applicant, owner, and
contractor;

The Board of Appeals of the Town of Madison, Maine, may, upon
written application of an aggrieved party, hear and decide appeals
where it is alleged that there is an error in any order, requirement,
decision, or determination made by, or failure to act by, the Code
Enforcement Officer or Planning Board in the administration or enforcement
of the provisions of this chapter. The Board of Appeals may grant
a variance from the requirements of this chapter consistent with state
law and the following criteria:
A.
Variances shall not be granted within any designated regulatory floodway
if any increase in flood levels during the base flood discharge would
result.
B.
Variances shall be granted only upon:
(1)
A showing of good and sufficient cause; and
(2)
A determination that should a flood comparable to the base flood
occur, the granting of a variance will not result in increased flood
heights, additional threats to public safety, public expense, or create
nuisances, cause fraud or victimization of the public or conflict
with existing local laws or chapters; and
(3)
A showing that the existence of the variance will not conflict with
other state, federal or local laws or chapters; and
(4)
A determination that failure to grant the variance would result in
undue hardship, which in this subsection means:
(a)
That the land in question cannot yield a reasonable return unless
a variance is granted; and
(b)
That the need for a variance is due to the unique circumstances
of the property and not to the general conditions in the neighborhood;
and
(c)
That the granting of a variance will not alter the essential
character of the locality; and
(d)
That the hardship is not the result of action taken by the applicant
or a prior owner.
C.
Variances shall only be issued upon a determination that the variance
is the minimum necessary, considering the flood hazard, to afford
relief, and the Board of Appeals may impose such conditions to a variance
as it deems necessary.
D.
Variances may be issued by a community for new construction, substantial
improvements, or other development for the conduct of a functionally
dependent use, provided that:
E.
Variances may be issued for the repair, reconstruction, rehabilitation,
or restoration of historic structures upon the determination that:
(2)
The proposed repair, reconstruction, rehabilitation, or restoration
will not preclude the structure's continued designation as an
historic structure and the variance is the minimum necessary to preserve
the historic character and design of the structure.
F.
Any applicant who meets the criteria of § 422-10, Subsections A through E, shall be notified by the Board of Appeals in writing over the signature of the Chairman of the Board of Appeals that:
(1)
The issuance of a variance to construct a structure below the base
flood level will result in greatly increased premium rates for flood
insurance coverage; and
(2)
Such construction below the base flood level increases risks to life
and property; and
(3)
The applicant agrees in writing that the applicant is fully aware
of all the risks inherent in the use of land subject to flooding,
assumes those risks and agrees to indemnify and defend the municipality
against any claims filed against it that are related to the applicant's
decision to use land located in a floodplain and that the applicant
individually releases the municipality from any claims the applicant
may have against the municipality that are related to the use of land
located in a floodplain.
G.
Appeal procedure for administrative and variance appeals.
(1)
An administrative or variance appeal may be taken to the Board of
Appeals by an aggrieved party within 30 days after receipt of a written
decision of the Code Enforcement Officer or Planning Board.
(2)
Upon being notified of an appeal, the Code Enforcement Officer or
Planning Board, as appropriate, shall transmit to the Board of Appeals
all of the papers constituting the record of the decision appealed
from.
(3)
The Board of Appeals shall hold a public hearing on the appeal within
35 days of its receipt of an appeal request.
(4)
The person filing the appeal shall have the burden of proof.
(5)
The Board of Appeals shall decide all appeals within 35 days after
the close of the hearing, and shall issue a written decision on all
appeals.
(6)
The Board of Appeals shall submit to the Code Enforcement Officer
a report of all variance actions, including justification for the
granting of the variance and an authorization for the Code Enforcement
Officer to issue a flood hazard development permit, which includes
any conditions to be attached to said permit.
(7)
Any aggrieved party who participated as a party during the proceedings
before the Board of Appeals may take an appeal to Superior Court in
accordance with state laws within 45 days from the date of any decision
of the Board of Appeals.
A.
It shall be the duty of the Code Enforcement Officer to enforce the
provisions of this chapter pursuant to 30-A M.R.S.A. § 4452.
B.
The penalties contained in 30-A M.R.S.A. § 4452 shall apply
to any violation of this chapter.
C.
In addition to any other actions, the Code Enforcement Officer, upon
determination that a violation exists, shall submit a declaration
to the Administrator of the Federal Insurance Administration requesting
a denial of flood insurance. The valid declaration shall consist of:
(1)
The name of the property owner and address or legal description of
the property sufficient to confirm its identity or location;
(2)
A clear and unequivocal declaration that the property is in violation
of a cited state or local law, or chapter;
(3)
A clear statement that the public body making the declaration has
authority to do so and a citation to that authority;
(4)
Evidence that the property owner has been provided notice of the
violation and the prospective denial of insurance; and
(5)
A clear statement that the declaration is being submitted pursuant
to Section 1316 of the National Flood Insurance Act of 1968, as amended.
If any section or provision of this chapter is declared by the
courts to be invalid, such decision shall not invalidate any other
section or provision of this chapter.
This chapter shall not in any way impair or remove the necessity
of compliance with any other applicable rule, chapter, regulation,
bylaw, permit, or provision of law. Where this chapter imposes a greater
restriction upon the use of land, buildings, or structures, the provisions
of this chapter shall control.
A.
Unless specifically defined below, words and phrases used in this
chapter shall have the same meaning as they have at common law and
to give this chapter its most reasonable application. Words used in
the present tense include the future, the singular number includes
the plural, and the plural number includes the singular. The word

including but not limited to buildings or other structures, mining,
dredging, filling, grading, paving, excavation, drilling operations
or storage of equipment or materials.
A nonbasement building:
Built, in the case of a building in Zones A or AE, to have the
top of the elevated floor elevated above the ground level by means
of pilings, columns, post, piers, or shear walls; and
Adequately anchored so as not to impair the structural integrity
of the building during a flood of up to one foot above the magnitude
of the base flood.
In the case of Zones A or AE, "elevated building" also includes a building elevated by means of fill or solid foundation perimeter walls with hydraulic openings sufficient to facilitate the unimpeded movement of flood waters, as required in § 422-7L.
An official form (FEMA Form 81-31, 05/93, as amended) that:
An examination, evaluation and determination of flood hazards
and, if appropriate, corresponding water surface elevations.
An official map of a community, on which the Administrator
of the Federal Insurance Administration has delineated both the special
hazard areas and the risk premium zones applicable to the community.
See "flood elevation study."
The collapse or subsidence of land along the shore of a lake or other body of water as a result of erosion or undermining caused by waves or currents of water exceeding anticipated cyclical levels or suddenly caused by an unusually high water level in a natural body of water, accompanied by a severe storm, or by an unanticipated force of nature, such as flash flood or an abnormal tidal surge, or by some similarly unusual and unforeseeable event which results in flooding as defined in Subsection (1)(a) of this definition.
The operation of an overall program of corrective and preventive
measures for reducing flood damage, including but not limited to emergency
preparedness plans, flood control works, and floodplain management
regulations.
Zoning chapters, subdivision regulations, building codes,
health regulations, special purpose chapters (such as a floodplain
chapter, grading chapter, and erosion control chapter) and other applications
of police power. The term describes such state or local regulations,
in any combination thereof, which provide standards for the purpose
of flood damage prevention and reduction.
Any land area susceptible to being inundated by water from
any source (see flooding).
Any combination of structural and nonstructural additions,
changes, or adjustments to structures which reduce or eliminate flood
damage to real estate or improved real property, water and sanitary
facilities, structures and contents.
See "regulatory floodway."
The lines marking the limits of floodways on federal, state,
and local floodplain maps.
A factor of safety usually expressed in feet above a flood
level for purposes of floodplain management. Freeboard tends to compensate
for the many unknown factors, such as wave action, bridge openings,
and the hydrological effect of urbanization of the watershed, that
could contribute to flood heights greater than the height calculated
for a selected size flood and floodway conditions.
A use which cannot perform its intended purpose unless it
is located or carried out in close proximity to water. The term includes
only docking facilities, port facilities that are necessary for the
loading and unloading of cargo or passengers, and shipbuilding and
ship repair facilities, but does not include long-term storage or
related manufacturing facilities.
Any structure that is:
Listed individually in the National Register of Historic Places
(a listing maintained by the Department of Interior) or preliminarily
determined by the Secretary of the Interior as meeting the requirements
for individual listing on the National Register;
Certified or preliminarily determined by the Secretary of the
Interior as contributing to the historical significance of a registered
historic district or a district preliminarily determined by the Secretary
of the Interior to qualify as a registered historic district;
Individually listed on a state inventory of historic places
in states with historic preservation programs which have been approved
by the Secretary of the Interior; or
Individually listed on a local inventory of historic places
in communities with historic preservation programs that have been
certified either:
For purposes of this chapter, an elevation established for
a specific site to which all other elevations at the site are referenced.
This elevation is generally not referenced to the National Geodetic
Vertical Datum (NGVD) or any other established datum and is used in
areas where mean sea level data is too far from a specific site to
be practically used.
The lowest floor of the lowest enclosed area (including basement). An unfinished or flood-resistant enclosure, usable solely for parking of vehicles, building access or storage in an area other than a basement area is not considered a building's lowest floor, provided that such enclosure is not built so as to render the structure in violation of the applicable nonelevation design requirements described in § 422-7 of this chapter.
A structure, transportable in one or more sections, which
is built on a permanent chassis and is designed for use with or without
a permanent foundation when connected to the required utilities. For
floodplain management purposes the term "manufactured home" also includes
park trailers, travel trailers, and other similar vehicles placed
on a site for greater than 180 consecutive days.
A parcel (or contiguous parcels) of land divided into two
or more manufactured home lots for rent or sale.
For purposes of the National Flood Insurance Program, the
National Geodetic Vertical Datum (NGVD) of 1929, or other datum, to
which base flood elevations shown on a community's Flood Insurance
Rate Map are referenced.
All development that is not new construction or a substantial improvement, such as repairs, maintenance, renovations, or additions, whose value is less than 50% of the market value of the structure. It also includes, but is not limited to accessory structures as provided for in § 422-7J, mining, dredging, filling, grading, paving, excavation, drilling operations, storage of equipment or materials, deposition or extraction of materials, public or private sewage disposal systems or water supply facilities that do not involve structures; and nonstructural projects such as bridges, dams, towers, fencing, pipelines, wharves, and piers.
The national vertical datum, whose standard was established
in 1929, which is used by the National Flood Insurance Program (NFIP).
NGVD was based upon mean sea level in 1929 and also has been called
"1929 Mean Sea Level (MSL)."
Structures for which the start of construction commenced
on or after the effective date of floodplain management regulations
adopted by a community and includes any subsequent improvements to
such structures.
The national datum whose standard was established in 1988,
which is the new vertical datum used by the National Flood Insurance
Program (NFIP) for all new Flood Insurance Rate Maps. NAVD is based
upon vertical datum used by other North American countries such as
Canada and Mexico and was established to replace NGVD because of constant
movement of the earths crust, glacial rebound and subsidence, and
the increasing use of satellite technology.
A vehicle which is:
Built on a single chassis;
Four hundred square feet or less when measured at the largest
horizontal projection, not including slideouts;
Designed to be self-propelled or permanently towable by a motor
vehicle; and
Designed primarily not for use as a permanent dwelling but as
temporary living quarters for recreational, camping, travel, or seasonal
use.
The channel of a river or other watercourse and the adjacent
land areas that must be reserved in order to discharge the base flood
without cumulatively increasing the water surface elevation more than
one foot; and
In riverine areas is considered to be the channel of a river
or other watercourse and the adjacent land areas to a distance of
1/2 the width of the floodplain, as measured from the normal high-water
mark to the upland limit of the floodplain.
Relating to, formed by, or resembling a river (including
tributaries), stream, brook, etc.
See "area of special flood hazard."
The date the building permit was issued, provided that the
actual start of construction, repair, reconstruction, rehabilitation,
addition, placement, substantial improvement or other improvement
was within 180 days of the permit date. The actual start means either
the first placement of permanent construction of a structure on a
site, such as the pouring of slab or footings, the installation of
piles, the construction of columns, or any work beyond the stage of
excavation; or the placement of a manufactured home on a foundation.
Permanent construction does not include land preparation, such as
clearing, grading and filling; nor does it include the installation
of streets and/or walkways; nor does it include excavation for basement,
footings, piers, or foundations or the erection of temporary forms;
nor does it include the installation on the property of accessory
buildings, such as garages or sheds not occupied as dwelling units
or not part of the main structure. For a substantial improvement,
the actual start of construction means the first alteration of any
wall, ceiling, floor, or other structural part of a building, whether
or not that alteration affects the external dimensions of the building.
For floodplain management purposes, a walled and roofed building.
A gas or liquid storage tank that is principally above ground is also
a structure.
Damage of any origin sustained by a structure whereby the
cost of restoring the structure to its before-damage condition would
equal or exceed 50% of the market value of the structure before the
damage occurred.
Any reconstruction, rehabilitation, addition, or other improvement
of a structure, the cost of which equals or exceeds 50% of the market
value of the structure before the start of construction of the improvement.
This term includes structures which have incurred substantial damage,
regardless of the actual repair work performed. The term does not,
however, include either:
Any project for improvement of a structure to correct existing
violations of state or local health, sanitary, or safety code specifications
which have been identified by the local code enforcement official
and which are the minimum necessary to assure safe living conditions;
or
Any alteration of an historic structure, provided that the alteration
will not preclude the structure's continued designation as an
historic structure, and a variance is obtained from the Town of Madison's
Board of Appeals.
A grant of relief by a community from the terms of a floodplain
management regulation.
The failure of a structure or development to comply with
a community's floodplain management regulations.
This chapter repeals and replaces any municipal chapter previously
enacted to comply with the National Flood Insurance Act of 1968 (P.L.
90-488, as amended).
