[Amended 4-26-2021 ATM by Art. 31, AG 12-2-2021, eff. 4-26-2021]
8.1.1.
Purpose. The purpose of the Floodplain Overlay District is to:
1.
Ensure public safety through reducing the threats to life and personal injury;
2.
Eliminate new hazards to emergency response officials;
3.
Prevent the occurrence of public emergencies resulting from water quality, contamination, and pollution due to flooding;
4.
Avoid the loss of utility services which if damaged by flooding would disrupt or shut down the utility network and impact regions of the community beyond the site of flooding;
5.
Eliminate costs associated with the response and cleanup of flooding conditions;
6.
Reduce damage to public and private property resulting from flooding waters;
7.
Discourage individuals from purchasing lands which are unsuitable for intended purposes because of flood hazard;
8.
Control filling, grading and mineral extraction which may increase flood damage;
9.
Regulate the construction of levees, jetties and other works, which may increase flood damage to lands, which may be subject to flooding.
8.1.2.
Location of Floodplain District. The Floodplain District is herein established as an overlay district. The District includes all special flood hazard areas within Middleborough designated on the Plymouth County Flood Insurance Rate Map (FIRM) dated July 6, 2021, 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 and further defined by the Plymouth County Flood Insurance Study (FIS) report dated July 6, 2021. The FIRM and FIS report are incorporated herein by reference and are on file with the Town Clerk, Planning Board, Building Inspector and Conservation Commission, and are hereby made a part of the Zoning Map and are incorporated herein by reference.
8.1.3.
Regulations. A Floodplain District shall be considered to be superimposed over any other district established by this bylaw. Land in a Floodplain District may be used for any purpose otherwise permitted in the underlying district except:
1.
No building or structure may be erected in a Floodplain District; provided that the Zoning Board of Appeals may grant a special permit in accordance with the provisions of Section 9.4 for the construction or use of a building or structure which:
2.
No dumping, filling, dredging, excavation, transfer or removal of any material which will reduce the natural flood water storage capacity of the land or will interfere with the natural flow of water over the land shall be permitted;
3.
If any land included in a Floodplain District is found by the Zoning Board of Appeals not in fact to be subject to seasonal or periodic flooding, the Zoning Board of Appeals may grant a special permit in accordance with the provisions of Section 9.4 for the use of such land for any purpose permitted in the underlying district. The Zoning Board of Appeals may consider the elevation of the particular land, Letter of Map Amendment (LOMA), its history of flooding and any other relevant evidence. The Zoning Board of Appeals may request and consider information on the application from any other public official, board or agency;
4.
When an application is made for a building permit and the Building Inspector determines that said use of land is within the Floodplain District, the Building Inspector shall require the applicant for such permit to provide, as part of the application, a plan of the lot on which such building is intended to be built showing the land contours in two-foot intervals, related to elevations above mean sea level, indicating the benchmarks used and certified by a registered land surveyor.
5.
The provisions of Section 8.1 shall not apply to any building or structure in a Floodplain District that was in existence at the time of the adoption of Section 8.1 and notwithstanding the provisions of Section 3.3, such buildings may be repaired, restored, altered, enlarged or rebuilt in compliance with all other zoning laws and applicable state and municipal laws and regulations, provided that any such altered, enlarged or rebuilt building shall not affect the natural flow patterns of any watercourse.
8.1.4.
Requirement to Submit New Technical Data. If the Town acquires data that changes the base flood elevation in the FEMA mapped Special Flood Hazard Areas, the Floodplain Administrator will, within six (6) months, notify FEMA of these changes by submitting the technical or scientific data that supports the change(s). Notification shall be submitted to:
FEMA Region I Risk Analysis Branch Chief 99 High Street, 6th Floor, Boston, MA 02110 |
And copy of notification to: |
Massachusetts NFIP State Coordinator MA Dept. of Conservation & Recreation, 251 Causeway Street, Boston, MA 02114 |
8.1.5.
Variances to Building Code Floodplain Standards. The Floodplain Administrator will request from the State Building Code Appeals Board a written and/or audible copy of the portion of the hearing related to the variance, and will maintain this record in the community's files.
The Floodplain Administrator shall also issue a letter to the property owner regarding potential impacts to the annual premiums for the flood insurance policy covering that property, in writing over the signature of a community official that (i) the issuance of a variance to construct a structure below the base flood level will result in increased premium rates for flood insurance up to amounts as high as $25 for $100 of insurance coverage and (ii) such construction below the base flood level increases risks to life and property.
Such notification shall be maintained with the record of all variance actions for the referenced development in the floodplain overlay district.
8.1.6.
Variances to Local Zoning Bylaws Related to Community Compliance with the National Flood Insurance Program (NFIP). A variance from theses floodplain bylaws must meet the requirements set out by State law, and may only be granted if: 1) Good and sufficient cause and exceptional non-financial hardship exist; 2) the variance will not result in additional threats to public safety, extraordinary public expense, or fraud or victimization of the public; and 3) the variance is the minimum action necessary to afford relief.
8.1.7.
Permitted Uses. The following uses of low flood damage potential and causing no obstructions to flood flows are allowed, provided they are permitted in the underlying district and they do not require structures, fill or storage of materials or equipment:
1.
Agricultural uses such as farming, grazing, truck farming and horticulture;
2.
Forestry and nursery uses;
3.
Outdoor recreational uses, including fishing, boating, hunting and play areas;
4.

8.1.11.
Base Flood Elevation Data for Subdivision Proposals. When proposing subdivision or other developments greater than 50 lots or 5 acres (whichever is less), the proponent must provide technical data to determine base flood elevations for each developable parcel shown on the design plans.
8.1.12.
Unnumbered A Zones. In A Zones, in the absence of FEMA BFE data and floodway data, the Building Department 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 or above base flood level, and for prohibiting encroachments in floodways.
8.1.13.
Floodway Encroachment. In Zones A, A1 - A30, 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.
In Zones A1 - A30 and AE, along watercourses that have a regulatory floodway designed on the Town's FIRM encroachments are prohibited in the regulatory floodway, which would result in any increase in flood levels within the community during the occurrence of the base flood discharge.
8.1.14.
Watercourse Alterations or Relocations in Riverine Areas. In a riverine situation, the Conservation Agent shall notify the following of any alteration or relocation of a watercourse:
