  • (July 29, 2013) Presentation on Sea Level Rise – Brant Rock, MA  On July 29, 2013, the Board of Selectmen held a public meeting at 7:00 PM at Haddad’s Ocean Café in Brant Rock. The purpose of the meeting was to present the results of a study on sea level rise in Marshfield, Scituate and Duxbury, Massachusetts. The Town’s consultants, Kleinfelder Northeast,  presented their final report showing projections of sea level elevations in 25, 50 and 75 years from now. The projections show the locations of roads, public and private property that will likely be flooded from sea level rise. About 150 people attended the informational meeting.

  • (May 16, 2013) Sea Level Rise Impacts Presentation Last year, Marshfield, Duxbury and Scituate  received a $30,000 New England Municipal Coastal Resilience Initiative Grant from the Gulf of Maine Council on the Marine Environment. On Thursday May 16, 2013 the consultants for the project Kleinfelder Northeast Inc. will host a public workshop to present their findings on the impacts of sea level rise in the three (3) community study area.  The meeting was held on May 16, 2013 at 7:00 PM in the Scituate Harbor Community Building, 44 Jericho Road, Scituate.

  • (March, 2013) Marshfield, Scituate and Duxbury applied for and received a $30,000 grant from the Gulf of Maine Council on the Marine Environment, to model the effects of sea level rise in areas vulnerable to coastal flooding.  3-D image modeling, shown below, will be used to show the height of sea level in relation to buildings and utilities in normal and storm conditions.

Recently developed, highly accurate topographic data produced with LIDAR (Light Detection and Ranging) will be used as base maps of the local terrain.  The towns recently hired the Engineering firm Kleinfelder New England, of Cambridge, MA to complete the project.  The Scope of Work for the project includes the following:

  1. Making future projections of sea level rise in 25 years, 50 years and 75 years from present day;
  2. Produce color maps of areas projected to be flooded in the three time frames listed above and in a worst case scenario, assuming 100 year storm event tidal surge conditions based on FEMA flood elevations.
  3. Assess the impacts to natural resources in the three town area based on the inundation models produced for the three time frames;
  4. 3D imaging of flooding for 5 locations in each town, 15 total; Conduct risk assessments on coastal properties;
  5. Recommend adaptation and mitigation measures
  • (December, 2011) – Duxbury, Marshfield and Scituate awarded a $30,000 grant to study sea level rise projections. This Gulf of Maine Council grant will be used to study sea level rise projections 25, 50 and 100 years out to determine areas that will be vulnerable to flooding. The Town Planners will then assess the risks to public infrastructure, private property and natural resources. Maps will be used to educate the public about the areas that will be at risk from sea level rise. The source of funding for the grant came from NOAA. One grant was awarded to each of 4 New England states. We received the $30,000 grant for Massachusetts which will be supplemented by over $15,400 of in-kind services from the three Town Planners and a Regional Planner from the Metropolitan Area Planning Council. Paul Halkiotis, Marshfield’s town planner, will serve as the project manager for the grant.
  • South_Shore_Coastal_Adaptation_Planning_Report_12-31-11 – The report contains a compilation of exising studies, an explanation of sea level rise trends and projections, inventories of coastal structures such as seawalls and jetties, strategies to avoid or mitigate flooding impacts and funding options for coastal infrastructure to minimize flooding impacts.
  • (October 27, 2011) – Planning for Sea Level Rise Workshop – Duxbury, Marshfield and Scituate hosted a workshop (Long Range Planning for Sea Level Rise) at the Marshfield Senior Center as part of a grant from the Metropolitan Area Planning Commission (MAPC). Presenters were Jim O’Connell, Scituate Conservation Agent, Anne Herbst, Hull, Conservation Administrator and Julia Knisel, MA Coastal Zone Management.
  • (April 2011) Scituate, Marshfield and Duxbury received a District Local Technical Assistance (DLTA) grant from the Metropolitan Area Planning Council to study general changes in coastal hazard impacts that could occur due to climate change, in particular, the impacts from sea level rise and a change in storm intensity and frequency. The project is exploring current and future coastal vulnerabilities, identifying a range of possible adaptations and gathering information about resources that could support local actions and strategies. Paul Halkiotis, Marshfield Town Planner, Laura Harbottle, Scituate Town Planner and Tom Broaderick, Duxbury Town Planner along with Barry Keppard, MAPC are coordinating the study.

  • (April 3, 2011)Fighting a losing battle with the sea” Scientists increasingly believe the rise in sea levels will accelerate markedly as ocean waters warm and ice sheets melt. The effect could be greatest in the Northeast where many sea walls are in woeful disrepair.” ( Boston Sunday Globe by Beth Daley)
  • (March 10, 2011) Marshfield Energy Committee hosted a MA State Climate Protection Network Meeting at Seth Ventress Building.  About 50 people including federal, state and local officials and citizens attended. ICLEI – Local Governments for Sustainability for arranged the meeting. Speakers from NASA, EPA, MA Department of Energy Resources, Boston and Cambridge made presentations about Climate Change. Dr. Cynthia Rosenzweig, a Senior Research Scientist at NASA Goddard Institute for Space Studies was a featured speaker. An interesting anecdote is that Dr. Rosenzweig and six generations of her family have spent summers in Marshfield. Climate Protection Meeting Agenda
