Editor's Note: This order also repealed former Ch. 146, Flood Damage Prevention, adopted 11-12-1991 as Ord. No. 100-91.
The Town of Standish, Maine, elects to comply with the requirements of the National Flood Insurance Act of 1968 (P.L. 90-488, as amended). The National Flood Insurance Program, established in the aforesaid Act, provides that areas of the town having a special flood hazard be identified by the Federal Emergency Management Agency (FEMA) 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 Standish, Maine.
The areas of special flood hazard, Zones A and A1-30, identified by FEMA in a report entitled "Flood Insurance Study - Town of Standish, Maine, Cumberland County," dated November 19, 1980, with accompanying Flood Insurance Rate Map dated October 16, 1984, is hereby adopted by reference and declared to be a part of this chapter.
Before any construction or other development (as defined in § 146-13) including the placement of manufactured homes, begins within any areas of special flood hazard established in § 146-1, 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 Standish, Maine.
The application for a Flood Hazard Development Permit shall be submitted to the Code Enforcement Officer and shall include:
The name and address of the applicant.
An address and a map indicating the location of the construction site.
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.
A statement of the intended use of the structure.
A statement as to the type of sewage system proposed.
Specification of dimensions of the proposed structure.
The elevation in relation to the National Geodetic Vertical Datum (NGVD), or to a locally established datum in Zone A only, of the:
Base flood at the proposed site of all new or substantially improved structures, which is determined:
In Zones A1-30 from data contained in the Flood Insurance Study - Town of Standish, Maine, as described in § 146-1; or
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.
Highest and lowest grades at the site adjacent to the walls of the proposed building.
Lowest floor, including basement; and whether or not such structures contain a basement.
Level, in the case of nonresidential structures only, to which the structure will be floodproofed.
A description of a base flood elevation reference point established on the site of all new or substantially improved structures.
A written certification by a registered land surveyor that the elevations shown on the application are accurate.
A description of the extent to which any watercourse will be altered or relocated as a result of the proposed development.
A nonrefundable application fee as established by the town shall be paid to the Town Clerk, and a copy of a receipt for the same shall accompany the application.
An additional fee may be charged if the Code Enforcement Officer and/or Board of Appeals 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 Board of Appeals.
The Code Enforcement Officer shall:
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 § 146-6, Development standards, have or will be met.
Utilize, in the review of all flood hazard development permit applications, the base flood data contained in the Flood Insurance Study - Town of Standish, Maine, as described in § 146-1. In special flood hazard areas where base flood elevation data are 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 §§ 146-3G(1)(b), 146-6I and 146-8D, in order to administer § 146-6 of this chapter.
Make interpretations of the location of boundaries of special flood hazard areas shown on the maps described in § 146-1 of this chapter.
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. § 1334.
Notify adjacent municipalities, the Department of Environmental Protection and the Maine State Planning Office prior to any alteration or relocation of a watercourse.
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 an application for Part II of the Flood Hazard Development Permit and shall include an elevation certificate completed by a registered Maine surveyor for compliance with the elevation requirements of § 146-6F, G, H and K. Following review of the application, which review 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.
Maintain, as a permanent record, copies of all Flood Hazard Development Permits issued and data relevant thereto, including reports of the Board of Appeals on variances granted under the provisions of § 146-9 of this chapter, and copies of elevation certificates and certificates of compliance required under the provisions of § 146-7 of this chapter.
All developments in areas of special flood hazard shall meet the following applicable standards:
New construction or substantial improvement of any structure shall:
Be designed or modified and adequately anchored to prevent flotation, collapse or lateral movement of the structure resulting from hydrodynamic and hydrostatic loads, including the effects of buoyancy;
Use construction materials that are resistant to flood damage;
Use construction methods and practices that will minimize flood damage; and
Use 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 flooding conditions.
All new and replacement water supply systems shall be designed to minimize or eliminate infiltration of floodwaters into the systems.
All new and replacement sanitary sewage systems shall be designed and located to minimize or eliminate infiltration of floodwaters into the system and discharges from the system into floodwaters.
On-site waste disposal systems shall be located and constructed to avoid impairment to them or contamination from them during floods.
All development shall be constructed and maintained in such a manner that no reduction occurs in the flood-carrying capacity of any watercourse.
New construction or substantial improvement of any residential structure located within:
Zones A1-30, AE and AH shall have the lowest floor (including basement) elevated to at least one foot above the base flood elevation.
New construction or substantial improvement of any nonresidential structure located within:
Zone A1-30 shall have the lowest floor (including basement) elevated to at least one foot above the base flood elevation or, together with attendant utility and sanitary facilities, shall:
Be floodproofed to at least one foot above the base flood level so that below that elevation the structure is watertight with walls substantially impermeable to passage of water;
Have structural components capable of resisting hydrostatic and hydrodynamic loads and the effects of buoyancy; and
Be certified by a registered professional engineer or architect that the design and methods of construction are in accordance with accepted standards of practice for meeting the provisions of this section. Such certification shall be provided with the application for a Flood Hazard Development Permit, as required by § 146-3J and shall include a record of the elevation above mean sea level of the lowest floor including basement.
New or substantially improved manufactured homes located within:
Zones A1-30 shall:
Be elevated on a permanent foundation so that the lowest floor is at least one foot above the base flood elevation; and
Be securely anchored to an adequately anchored foundation system to resist flotation, collapse or lateral movement. Methods of anchoring may include but are not limited to:
Over-the-top ties anchored to the ground at the four corners of the manufactured home, plus two additional ties per side at intermediate points (homes less than 50 feet long require one additional tie per side); or by
Frame ties at each corner of the home, plus five additional ties along each side at intermediate points (homes less than 50 feet long require four additional ties per side).
Recreational vehicles located within:
Zones A1-A30, AH and AE shall either:
Be on the site for fewer than 180 consecutive days;
Be fully licensed and ready for highway use. 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; or
In Zone A1-30 encroachments, including fill, new construction, substantial improvement and other development shall not be permitted in riverine areas for which a regulatory floodway is designated on the community's Flood Boundary and Floodway Map, unless a technical evaluation certified by a registered professional engineer is provided demonstrating that such encroachments will not result in any increase in flood levels within the community during the occurrence of the base flood discharge.
In Zone A1-30 riverine areas for which no regulatory floodway is designated, encroachments, including fill, new construction, substantial improvement and other development shall not be permitted unless a technical evaluation certified by a registered professional engineer is provided demonstrating that the cumulative effect of the proposed development, when combined with all other existing development and anticipated development, will not increase the water surface elevation of the base flood more than one foot at any point within the community.
In Zone A riverine areas, in which the regulatory floodway is determined to be the channel of the 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, encroachments, including fill, new construction, substantial improvement and other development shall not be permitted unless a technical evaluation certified by a registered professional engineer is provided meeting the requirements of § 146-6J(2).
New construction or substantial improvement of any structure in Zones A1-30 and A that meets the development standards of § 146-6, including the elevation requirements of Subsections F, G or H, and is elevated on posts, columns, piers, piles, stilts or crawlspaces less than three feet in height may be enclosed below the elevation requirements, provided that all the following criteria are met or exceeded:
Walls, with the exception of crawlspaces less than three feet in height, shall not be part of the structural support of the building;
Enclosed areas shall be designed to automatically equalize hydrostatic flood forces on exterior walls by allowing for the entry and exit of floodwater. Designs for meeting this requirement must either:
Be certified by a registered professional engineer or architect; or
Meet or exceed the following minimum criteria:
A minimum of two openings having a total net area of not less than one square inch for every square foot of the enclosed area shall be provided;
The bottom of all openings shall be no higher than one foot above the lowest grade; and
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;
The enclosed area shall not be used for human habitation; and
The enclosed area may be used for building maintenance, access, parking vehicles or storing of articles and equipment used for maintenance of the building.
No land in a special flood hazard area shall be occupied or used and no structure which is constructed or substantially improved shall be occupied until a certificate of compliance is issued by the Code Enforcement Officer, subject to the following provisions:
The application for a certificate of compliance shall be submitted by the applicant in writing along with a completed elevation certificate to the Code Enforcement Officer.
The Code Enforcement Officer shall review the application within 10 working days of receipt of the application and shall issue a Certificate of Compliance, provided that the building conforms with the provisions of this chapter.
The Planning Board shall, when reviewing subdivisions and other proposed developments that require review under other federal law, state law or local ordinances or regulations and all projects on five or more acres, or in the case of manufactured home parks divided into two or more lots, assure that:
All such proposals are consistent with the need to minimize flood damage.
All public utilities and facilities, such as sewer, gas, electrical and water systems, are located and constructed to minimize or eliminate flood damages.
Adequate drainage is provided so as to reduce exposure to flood hazards.
All proposals include base flood elevation and, in a riverine floodplain, floodway data.
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 § 146-6 of this chapter and that such requirement will be included in any deed, lease 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 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 Board of Appeals of the Town of Standish, Maine, 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 Board of Appeals may grant a variance from the requirements of this chapter consistent with state law and the following criteria:
Variances shall not be granted within any designated regulatory floodway if any increase in flood levels during the base flood discharge would result.
Variances shall be granted only upon:
A showing of good and sufficient cause;
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;
A showing that the existence of the variance will not conflict with other state, federal or local laws or ordinances; and
A determination that failure to grant the variance would result in "undue hardship," which in this subsection means:
That the land in question cannot yield a reasonable return unless a variance is granted;
That the need for a variance is due to the unique circumstances of the property and not to the general conditions in the neighborhood;
That the granting of a variance will not alter the essential character or the locality; and
That the hardship is not the result of action taken by the applicant or a prior owner.
Variances shall only be issued upon a determination that the variance is the minimum necessary, considering the flood hazard, to afford relief.
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:
Any applicant who meets the criteria of § 146-9A through E shall be notified by the Board of Appeals, in writing over the signature of the Chairman of the Board of Appeals, that:
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;
Such construction below the base flood level increases risks to life and property; and
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.
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.
It shall be the duty of the Code Enforcement Officer to enforce the provisions of this chapter pursuant to 30A M.R.S.A. § 4452.
The penalties contained in 30A M.R.S.A. § 4452 shall apply to any violation of this chapter.
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:
The name of the property owner and address or legal description of the property sufficient to confirm its identity or location;
A clear and unequivocal declaration that the property is in violation of a cited state or local law or ordinance;
A statement that the public body making the declaration has authority to do so and a citation to that authority;
Evidence that the property owner has been provided notice of the violation and the prospective denial of insurance; and
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.
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.

- (4) Individually listed on a local inventory of historic places in communities with historic preservation programs that have been certified either:
- LOCALLY ESTABLISHED DATUM
- 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.
- LOWEST FLOOR
- 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 § 146-6 of this chapter.
- MANUFACTURED HOME
- 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.

- ONE-HUNDRED-YEAR FLOOD
- See "base flood."
- RECREATIONAL VEHICLE
- A vehicle which is:
- (1) Built on a single chassis;
- (2) Four hundred square feet or less when measured at the largest horizontal projection;
- (3) Designed to be self-propelled or permanently towable by a light-duty truck; and
- (4) Designed primarily not for use as a permanent dwelling but as temporary living quarters for recreational, camping, travel or seasonal use.
- (1) 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
- (2) In riverine areas, 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.
- SPECIAL FLOOD HAZARD AREA
- See "area of special flood hazard."
- START OF CONSTRUCTION
- 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."
- SUBSTANTIAL DAMAGE
- 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.
- SUBSTANTIAL IMPROVEMENT
- 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:
- (1) 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
- (2) Any alteration of an historic structure, provided that the alteration will not preclude the structure's continued designation as an historic structure.
- 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).
