B.
Establishment. The Floodplain District (FPOD) is herein established as an overlay district shown on the Floodplain Overlay District map dated February 27, 2025. The district includes all special flood hazard areas within the Town of Wakefield designated as Zone A and AE, on the Middlesex County Flood Insurance Rate Map (FIRM) to be dated July 8, 2025, and to be issued by the Federal Emergency Management Agency (FEMA) for the administration of the National Flood Insurance Program. The exact boundaries of the district shall be defined by the 1%-chance base flood elevations shown on the FIRM as well as and further defined by the Middlesex County Flood Insurance Study (FIS) report to be dated July 8, 2025.
D.
Development regulations. The following requirements shall apply within the FPOD:
(1)
Obtaining a Special Permit from the Zoning Board of Appeals for all proposed construction or other development in the FPOD is required, including new construction or changes to existing buildings, placement of manufactured homes, placement of agricultural facilities, fences, sheds, storage facilities or drilling, mining, paving and any other development that might increase flooding or adversely impact flood risks to other properties.
(2)
In addition to the Special Permit, the proponent shall also obtain all local, state and federal permits that will be necessary in order to carry out the proposed development in the FPOD. The proponent must acquire all necessary permits and must demonstrate that all necessary permits have been acquired prior to the issuance of a Building Permit.
(3)
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)
In Zone AE, along watercourses that have a regulatory floodway designated on the Wakefield's FIRM encroachments are prohibited, including fill, new construction, substantial improvements, and other development within the adopted regulatory floodway unless it has been demonstrated through hydrologic and hydraulic analyses performed in accordance with standard engineering practice that the proposed encroachment would not result in any increase in flood levels within the community during the occurrence of the base flood discharge.
(5)
In A Zone, in the absence of FEMA base flood elevation (BFE) data and floodway data, the Board will obtain, review and reasonably utilize base flood elevation and floodway data available from a federal, state, or other source as criteria for requiring new construction, substantial improvements, or other development in Zone A as the basis for elevating residential structures to or above base flood level, for flood proofing or elevating nonresidential structures to be built at or above base flood level, and for prohibiting encroachments in floodways;
(6)
All subdivision and development proposals must be designed to assure that: Such proposals minimize flood damage; All public utilities and facilities are located and constructed to minimize or eliminate flood damage; and Adequate drainage is provided to reduce exposure to flood hazards.
(7)
When proposing subdivisions or other developments greater than 50 lots or five acres (whichever is less), the proponent must provide technical data to determine base flood elevations for each developable parcel shown on the design plans.
(8)
In A, A1-30, and AE Zones, all recreational vehicles to be placed on a site must be elevated and anchored in accordance with the zone's regulations for foundation and elevation requirements or be on the site for less than 180 consecutive days or be fully licensed and highway ready.
(9)
A variance from these floodplain bylaws must meet the requirements set out by state law, and may only be granted if: good and sufficient cause and exceptional non-financial hardship exist; the variance will not result in additional threats to public safety, extraordinary public expense, or fraud or victimization of the public; and the variance is the minimum action necessary to afford relief.
(10)
The floodplain management regulations found in this Floodplain District section shall take precedence over any less restrictive conflicting local laws, ordinances or codes.
(11)
The degree of flood protection required by this chapter is considered reasonable but does not imply total flood protection.
E.
Uses allowed within the floodplain district by special permit. The following uses may be permitted in the FPOD by the Zoning Board of Appeals through a Special Permit:
(1)
Any use permitted in the underlying district in which the land is situated, subject to the same use and development regulations as may otherwise apply thereto, whether by right or by Special Permit, provided that all development, including structural and non- structural activities, are in compliance with this chapter and with other state regulations.
F.
Uses allowed within the Floodplain District as of right. The following uses are permitted by-right within the FPOD when confirmed by the Town's Floodplain Administrator to not have an impact to the base flood elevation nor result in any increase in flood levels:
(1)
Construction and maintenance of at-grade roads, driveways, sidewalks, footpaths and recreation areas provided that they do not alter the existing topography in the FPOD;
(2)
Construction, maintenance and improvements of public sewer and water, including accessory facilities used for their operation, maintenance or improvement of ponds, ditches, and other water bodies incidental thereto;
(3)
Construction, maintenance and improvements to existing roads and systems used in the service of the public, including drainage, electric power (including conversion to underground facilities), gas, telephone, telegraph and other telecommunication devices;
(4)
Any use permitted in the underlying district in which the land is situated, subject to the same use and development restrictions as may otherwise apply thereto, provided that the land designated as being within the FPOD is found to be not, in fact, subject to flooding through a Letter of Map Amendment, Letter of Map Revision or physical map revision submitted to and approved by the Federal Emergency Management Agency.
G.
Special permit. Such Special Permit shall be applied for in the manner required by the Zoning Board of Appeals but shall be superscribed "Floodplain District Special Permit Application." The Building Inspector shall issue a building permit only as directed by the Board of Appeals.
(1)
The Planning Board and Conservation Commission shall submit to the Board written recommendations as to whether the Special Permit should be granted and any recommended restrictions that should be imposed upon the proposed use as a condition of such Special Permit.
H.
Site plan review. Applications for site plan approval of uses in the Floodplain District are reviewed by the Zoning Board of Appeals and complete applications are required in accordance with § 190-61. Site plans shall be at a suitable scale, prepared by a registered land surveyor or registered professional civil engineer.
