A.
Establishment of districts. The Floodplain District is herein established as an overlay district. The district includes all special flood hazard areas within Framingham designated as Zone A and AE on the Middlesex County Flood Insurance Rate Map (FIRM) issued by the Federal Emergency Management Agency (FEMA) for the administration of the National Flood Insurance Program (NFIP). The map panels of the Middlesex County FIRM that are wholly or partially within Framingham are panel numbers 25017C0501F, 25017C0502F, 25017C0503F, 25017C0504F, 25017C0506F, 25017C0508F, 25017C0509F, 25017C0511F, 25017C0512F, 25017C0514F, 25017C0516F, 25017C0517F, 25017C0518F, and 25017C0519F, dated July 7, 2014. The exact boundaries of the district may be defined by the 100-year base flood elevations shown on the FIRM and further defined by the Middlesex County Flood Insurance Study (FIS) report dated July 7, 2014. The FIRM and FIS report are incorporated herein by reference and are on file with the City Clerk, Department of Public Works, Inspectional Services Division, the Division of Planning and Community Development, and Conservation Commission.
B.
Applicability.
(1)
All proposed development in a Floodplain District shall require a permit from the Building Commissioner.
(2)
In addition to a permit from the Building Commissioner, any construction, enlargement, extension, or substantial improvement of a new or existing building for human habitation, normally allowed by right or authorized by special permit in a land area underlying a Floodplain District, shall require a special permit from the Zoning Board of Appeals (ZBA).
(3)
In the regulatory floodway, any development or encroachment, including fill, which would result in any increase in flood levels during the base flood shall be prohibited. In Zones A and AE, along watercourses that have not had a regulatory floodway designated, the best available federal, state, local, or other floodway data shall be used to prohibit encroachments in floodways which would result in any increase in flood levels within the community during the occurrence of the base flood discharge.
(4)
Base flood elevation data is required for subdivision proposals or other developments greater than 50 lots or five acres, whichever is the lesser, within unnumbered A Zones. All subdivision proposals must be designed to assure that:
C.
Application procedure. Prior to the filing of an application subject to this section, the applicant shall submit plans to the Building Commissioner. The Commissioner shall advise the applicant as to the pertinent sections of this chapter and the State Building Code, 780 CMR. If a special permit is required, the applicant shall then submit seven copies of the application to the ZBA, who shall forthwith transmit one copy each to the City Clerk, the Conservation Commission, the Board of Health, the Department of Public Works, the Division of Planning and Community Development, and the Planning Board. Such agencies shall, within 30 days of receiving said copy, submit a report containing recommendations and the reasons therefor to the ZBA, and may prescribe conditions deemed appropriate for the proposed use. The ZBA shall not render a decision on any such application until said recommendations have been received and considered, or until the thirty-day period has expired, whichever is earlier. Failure of such agencies to submit their respective recommendations shall be deemed concurrence thereto. To assist the ZBA in rendering its decision on the application, said application shall indicate at least the following:
(1)
All information normally required in a building permit application.
(2)
If approval for development must be obtained from the Commonwealth of Massachusetts or the United States government or any agency or subdivision thereof, such approval shall be obtained, and a copy of the document setting forth such approval, and any conditions imposed thereon, shall be filed with the ZBA as part of this application.
(3)
The boundary of the special flood hazard area and the regulatory floodway shall be drawn on a plan of the site, which shall also include contour lines at a maximum of two-foot intervals. Base flood elevation on this site plan shall be certified by a registered professional engineer, architect, or surveyor. In unnumbered A Zones, base flood elevation data from sources other than the FIRM shall be obtained and reasonably utilized.
(4)
Location of existing and proposed sewer disposal facilities, leaching fields, and other utilities.
(5)
For any building to be occupied as a residence, certification by a registered professional engineer, architect, or surveyor that the proposed structure has been planned and designed to have the lowest floor, including the basement, elevated above the level of the base flood.
(6)
For any building not to be occupied as a residence, either certification as above that the lowest floor will be elevated above the level of the base flood, or certification by a registered professional engineer or architect that the building is planned and designed so that it will be watertight and anchored to resist forces associated with the base flood.
(7)
Other information as may reasonably be required by the ZBA to ensure compliance with the provisions of this section.
D.
Conditions for approval. In rendering its decision, the ZBA shall evaluate the extent to which the application meets the following conditions:
(1)
All other necessary permits have been received from those governmental agencies from which approval is required by federal or state law.
(2)
New construction (including prefabricated buildings and mobile homes) and substantial improvements will be anchored to prevent flotation and lateral movement, and will be constructed with flood-resistant materials and methods.
(3)
Proposed development, including utilities, drainage, and paved areas, is located and designed to be consistent with the need to minimize flood damage.
(4)
The site plan includes all required information, including base flood elevation data.
(5)
New water and sewer systems (including on-site systems) are located and designed to minimize infiltration.
(6)
New and substantially improved residential buildings have been planned and designed to have the lowest floor (including basement) elevated to or above the base flood level.
(7)
New and substantially improved nonresidential buildings have been planned and designed to have the lowest floor (including basement) elevated to or above the base flood level or be floodproofed to or above that level.
(8)
Where floodproofing is used in lieu of elevation, the floodproofing methods used are adequate to withstand the forces associated with the base flood.
(9)
Proposed development will not encroach on the regulatory floodway.
E.
Certificate of occupancy. No building newly constructed or substantially improved within a Floodplain District shall be occupied or used without a certificate of occupancy signed by the Building Commissioner, which permit shall not be issued until the development complies in all respects with the site plan approved by the ZBA and any conditions imposed by the ZBA on the granting of a special permit for development in a Floodplain District. No certificate of occupancy shall be signed by the Building Commissioner until a post-construction elevation certificate/floodproofing certificate has been submitted, certifying that the building has been elevated above the level of the base flood or, for nonresidential buildings, that the building has been floodproofed at least to the base flood elevation. In cases where a variance has been granted by the ZBA permitting construction below the base flood level and/or without adequate floodproofing, a certificate of occupancy may be granted in accordance with the conditions imposed by the ZBA on the granting of a variance.
F.
Notification of watercourse alteration. In a riverine situation, the City Engineer shall notify the following of any alteration or relocation of a watercourse:
