Duxbury Letter of Map Revision (LOMR)

A Letter of Map Revision (LOMR) is the Federal Emergency Management Agency’s (FEMA's) official modification to an effective Flood Insurance Rate Map (FIRM). LOMRs can result in a physical change to the existing regulatory floodway, the effective Base Flood Elevations (BFEs), or the Special Flood Hazard Area (SFHA). LOMR reviews take up to 90 days to process, are subject to an appeal period, and usually become effective within six months after they are issued. Because a LOMR officially revises the effective FIRM, the flood hazard updates shown are used to rate flood insurance policies and enforce flood insurance and development requirements.

What is a Letter of Map Revision (LOMR)?

On August 14, 2019 Public Notice for a LOMR to the 2016 FEMA Flood maps in Duxbury was published in the Marshfield Mariner and Duxbury Clipper. This LOMR is part of the Towns of Marshfield’s and Duxbury’s efforts to improve the 2016 FEMA Flood Maps.

This LOMR will affect approximately 39 homes in Marshfield (within the storm surge influence of Duxbury Bay).

The Base Flood Elevations (BFE) for the 39 homes in Marshfield will change before the rest of Town. The Duxbury LOMR will not need to go to Duxbury Town Meeting.

Duxbury LOMR

The Duxbury LOMR will not need to go through the 90 day public comment period. When the FEMA review is complete on the LOMR, FEMA will issue a Letter of Map Revision Determination Document. The LOMR will become effective 4 months after the date FEMA issues the letter of Map Revision Determination Document. Duxbury’s changes involve 6 panels, some of those panels are only minimally affected by the map changes. Marshfield’s changes involve 14 panels. FEMA has a limit of 5 panels that can be modified by a LOMR. FEMA allowed Duxbury under a LOMR as an exception. Marshfield was not allowed as an exception because the map changes cover a large portion of the town.

LOMR Versus a Physical Map Revision (PMR)

The full Marshfield Flood maps change process (Physical Map Revision) is a longer process (already underway) and the FEMA work maps are expected within a month or two. Once the FEMA work maps are released and advertised in the newspaper the Town will have a 90 day comment/appeal period. After that period closes FEMA will produce the final maps and submit new final maps to the Town. Marshfield will need to bring these maps to Town Meeting (hopefully April ATM 2020) for an official vote to modify the Town’s Zoning Map.

Marshfield’s Physical Map Revision

The area inside the blue line is Duxbury LOMR area. The best way to describe the impact area for Marshfield residents is west side of Canal Street and the south side of Careswell Street.

The Duxbury LOMR will remove the VE (10,11, and13) zones from the portion of Marshfield influenced by Duxbury Bay. The majority of the Marshfield portion (mostly marsh) will go to an AE 11. This western panel of the map change from our initial review may affect: 1 home on Jayna Way home, 1 on Seaflower Lane and 3 homes Old Wharf Waye . Once the mapping layers are online we will know what if any change has occurred.

From our initial review the changes in the eastern portion of the map only impact the west side of Canal Street. This will include approximately: 12 homes on Canal Street, 7 homes on Columbus Road, 6 homes on Craddock Circle, 4 Homes on Craddock Road, 3 homes on Idaho Street, and 1 Home on Elmhurst Avenue.

Marshfield has identified the properties with homes in Marshfield with the street address, current and revised Flood information. The Town does not make the official determination. Under Federal law, the bank or lending institution are the ones responsible for making the official determination.

Again changes for the Marshfield residents in the Duxbury LOMR will take effect 4 months after FEMA approves the LOMR by issuing a letter of Map Revision Determination Document and doesn’t require a Marshfield Town Meeting vote.

However, the Marshfield Town Meeting is expected to confirm these changes for the Marshfield residents included in the Duxbury LOMR as part of the upcoming Physical Map Revision (hopefully April 2020 ATM).
