[HISTORY: Adopted by the Town Meeting of the Town of Casco 6-19-1999 by Art. 69. Amendments noted
where applicable.]
A.
Certain areas of the Town of Casco, 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 Casco, 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 this chapter.
C.
It is the intent of the Town of Casco, 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.
This body 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
to 3007, 4352 and 4401 to 4407.
E.
The National Flood Insurance Program, established in the aforesaid
Act, provides that areas of the Town of Casco 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 Casco, Maine.
F.
The areas of special flood hazard, Zones A and A1-30, are identified
by the Federal Emergency Management Agency in a report titled "Flood
Insurance Study - Town of Casco, Maine, Cumberland County," dated
November 5, 1980, which report, with accompanying Flood Insurance
Rate Map dated May 5, 1981, and Flood Boundary and Floodway Map dated
May 5, 1981, is hereby adopted by reference and declared to be a part
of this chapter.
[Amended 6-14-2017 by
Art. 27]
Before any construction or other development (as defined in § 200-13), including the placement of manufactured homes, begins within any areas of special flood hazard established in § 200-1, 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 ordinances of the Town of Casco, Maine.
The application for a flood hazard development permit shall
be submitted to the Code Enforcement Officer and shall include:
A.
The name, address and phone number of the applicant, owner, and contractor;
B.
An address and a map indicating the location of the construction
site;
C.
A site plan showing location of existing and/or proposed structures,
sewage disposal facilities, water supply facilities, areas to be cut
and filled, and lot dimensions;
D.
A statement of the intended use of the structure and/or development;
E.
A statement of the cost of the development, including all materials
and labor;
F.
A statement as to the type of sewage system proposed;
H.
The elevation in relation to the National Geodetic Vertical Datum
(NGVD), or to a locally established datum in Zone A only, of the:
(1)
Base flood at the proposed site of all new or substantially improved
structures, which is determined:
(a)
In Zones A1-30, from data contained in the Flood Insurance Study - Town of Casco, Maine, as described in § 200-1; or
(b)
In Zone A, to be the elevation of the ground at the intersection
of the floodplain boundary and a line perpendicular to the shoreline
which passes along the ground through the site of the proposed building;
(2)
Highest and lowest grades at the site adjacent to the walls of the
proposed building;
(3)
Lowest floor, including basement, and whether or not such structures
contain a basement; and
(4)
Level, in the case of nonresidential structures only, to which the
structure will be floodproofed;
I.
A description of an elevation reference point established on the
site of all new or substantially improved structures;
J.
A written certification by a professional land surveyor that the
elevations shown on the application are accurate;
L.
A description of the extent to which any watercourse will be altered
or relocated as a result of the proposed development; and
A.
A nonrefundable application fee as prescribed in the Town Fee Schedule
shall be paid to the Town Clerk and a copy of a receipt for the same
shall accompany the application.
[Amended 6-14-2017 by
Art. 27]
B.
An additional fee may be charged if the Code Enforcement Officer
and/or Appeals Board needs the assistance of a professional engineer
or other expert. The expert's fee shall be paid in full by the applicant
within 10 days after the Town submits a bill to the applicant. Failure
to pay the bill shall constitute a violation of this chapter and be
grounds for the issuance of a stop-work order. An expert shall not
be hired by the municipality at the expense of an applicant until
the applicant has either consented to such hiring in writing or been
given an opportunity to be heard on the subject. An applicant who
is dissatisfied with a decision of the Code Enforcement Officer may
appeal that decision to the Appeals Board.
The Code Enforcement Officer shall:
A.
Review all applications for the flood hazard development permit to assure that proposed building sites are reasonably safe from flooding and to determine that all pertinent requirements of § 200-6 (Development standards) have or will be met.
B.
Utilize, in the review of all flood hazard development permit applications, the base flood data contained in the Flood Insurance Study - Town of Casco, Maine, as described in § 200-1. In special flood hazard areas where base flood elevation data is not provided, the Code Enforcement Officer shall obtain, review and reasonably utilize any base flood elevation and floodway data from federal, state, or other sources, including information obtained pursuant to §§ 200-3H(1)(b), 200-6J and 200-8D, in order to administer § 200-6 of this chapter.
C.
Make interpretations of the location of boundaries of special flood hazard areas shown on the maps described in § 200-1 of this chapter.
D.
In the review of flood hazard development permit applications, determine
that all necessary permits have been obtained from those federal,
state, and local government agencies from which prior approval is
required by federal or state law, including but not limited to Section
404 of the Federal Water Pollution Control Act, Amendments of 1972,
33 U.S.C. § 1344.
E.
Notify adjacent municipalities, the Department of Environmental Protection,
and the Maine Floodplain Management Program in the State Planning
Office prior to any alteration or relocation of a watercourse and
submit copies of such notifications to the Federal Emergency Management
Agency.
F.
Issue one of the following flood hazard development permits based
on the type of development:
(1)
Issue a two-part flood hazard development permit for elevated structures. Part I shall authorize the applicant to build a structure to and including the first horizontal floor only above the base flood level. At that time the applicant shall provide the Code Enforcement Officer with a second elevation certificate completed by a professional land surveyor based on the Part I permit construction, "as built," for verifying compliance with the elevation requirements of § 200-6F, G or H. Following review of the elevation certificate data, which shall take place within 72 hours of receipt of the application, the Code Enforcement Officer shall issue Part II of the flood hazard development permit. Part II shall authorize the applicant to complete the construction project;
(2)
Issue a flood hazard development permit for floodproofing of nonresidential structures that are new construction or substantially improved nonresidential structures that are not being elevated but that meet the floodproofing standards of § 200-6G(1)(a), (b) and (c). The application for this permit shall include a floodproofing certificate signed by a registered professional engineer or architect; or
(3)
Issue a flood hazard development permit for minor development for
all development that is not new construction or a substantial improvement,
such as repairs, maintenance, or renovations, whose value is less
than 50% of the market value of the structure. Minor development also
includes, but is not limited to, 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, towers, fencing, and pipelines.

be provided;
[2]
The bottom of all openings shall be no higher than one foot
above the lowest grade; and
[3]
Openings may be equipped with screens, louvers, valves, or other
coverings or devices provided that they permit the entry and exit
of floodwaters automatically without any external influence or control
such as human intervention, including the use of electrical and other
nonautomatic mechanical means;
(3)

All proposals include base flood elevation and, in a riverine floodplain,
floodway data.
E.
Any proposed development plan shall include a statement that the developer will require that structures on lots in the development be constructed in accordance with § 200-6 of this chapter and that such requirement will be included in any deed, lease, purchase and sale agreement, or document transferring or expressing an intent to transfer any interest in real estate or structure, including but not limited to a time-share interest. The statement shall clearly articulate that the municipality may enforce any violation of the construction requirement and that fact shall also be included in the deed or any other document previously described. The construction requirement shall also be clearly stated on any map, plat, or plan to be signed by the Planning Board or local reviewing authority as part of the approval process.
The Appeals Board of the Town of Casco may, upon written application
of an aggrieved party, hear and decide appeals from determinations
of the Code Enforcement Officer in the administration of the provisions
of this chapter. The Appeals Board 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;
(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, or public expense, or
create nuisances, cause fraud or victimization of the public or conflict
with existing local laws or ordinances;
(3)
A showing that the issuance of the variance will not conflict with
other state, federal or local laws or ordinances; and
(4)
A determination that failure to grant the variance would result in
undue hardship, which in this subsection means that:
(a)
The land in question cannot yield a reasonable return unless
a variance is granted;
(b)
The need for a variance is due to the unique circumstances of
the property and not to the general conditions in the neighborhood;
(c)
The granting of a variance will not alter the essential character
of the locality; and
(d)
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.
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 by a community 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 a 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 Subsections A through E shall be notified by the Appeals Board in writing over the signature of the Chair of the Appeals Board 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 up to amounts as high as $25 per $100 of insurance coverage;
(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.
The Appeals Board 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.
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, regulation, or ordinance;
(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, ordinance, 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
"may" is permissive; "shall" is mandatory and not discretionary.

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

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 § 200-6 of this chapter.

improvement, such as repairs, maintenance, or renovations, whose value
is less than 50% of the market value of the structure. It includes,
but is not limited to, 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, towers, fencing, and pipelines.
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.
See "base flood."
A vehicle which is:
Built on a single chassis;
Four hundred square feet or less when measured at the largest
horizontal projection;

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
When not designated on the community's Flood Insurance Rate
Map or Flood Boundary and Floodway Map, it is considered to be the
channel of a river or other watercourse and the adjacent land areas

Art. 27]
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 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 a historic structure, provided that the alteration
will not preclude the structure's continued designation as a historic
structure and a variance is obtained from the community's Appeals
Board.
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 ordinance previously
enacted to comply with the National Flood Insurance Act of 1968 (P.L.
90-488, as amended).
