Lake Erie Consultation Coordination Officer and Open House Meetings

FEMA invites Lake Erie Shoreline public officials, property owners, realtors, lenders, and insurance agents to learn more about flood risk and hazard mitigation within their community at upcoming CCO and Open House meetings. The CCO meetings are hosted to provide county officials with an opportunity to review a recently completed preliminary Flood Insurance Study (FIS) and its accompanying preliminary Flood Insurance Rate Maps (FIRMs). The FIS and the FIRMs provide base flood (also known as the one percent annual chance event) information, designate areas that are subject to significant flood hazards within the county, and offer information that public officials may use when permitting development in the floodplain. During the CCO meetings, any changes in flood risk will be explained and participants will have an opportunity to provide feedback on the FIRMs and FIS report.

Following the CCO meetings, Open House meetings are hosted for the public to meet with representatives from various local, state, and federal agencies who will provide the most current information about flood risk, flood insurance, floodplain development regulations, and the process for floodplain mapping within their county. The newly prepared preliminary FIRMs will be on display. See FEMA’s Preliminary Flood Hazard Data page and FEMA’s Preliminary Flood Hazard Layer mapping application for additional information.

Lake Michigan Work Map Meetings

Local officials and technical stakeholders are being invited to community meetings to review and comment on FEMA’s draft coastal flood hazard work maps for the Lake Michigan Shoreline. FEMA’s outreach meetings for the 2017 work maps start in early July.

Each meeting will include a summary of the draft work maps, Q&A, and a breakout for review of community-specific data via printed and online maps. Staff members and officials representing villages, cities, and county government, regional organizations, non-governmental bodies, neighborhood associations, and harbor and shoreline protection engineers are encouraged to attend and to provide feedback within the 60-day comment period.

Link to Map Viewer User Guide to learn more about the Draft Work Maps.

Risk Data and Mitigation Workshop dates for Michigan Counties

FEMA has completed coastal flood hazard analysis and mapping in 7 Michigan counties along Lake Michigan and prepared draft workmaps depicting results of the study. We would like to invite you to attend the Risk Data and Mitigation Workshop for your county. The objectives for this meeting are to allow local review of work maps that show the results of the mapping project efforts to-date, as well as provide information about how your community can use this information to elevate risk awareness and stimulate mitigation actions. Each meeting will be 2 to 3hours in length, dedicated to accomplishing the following goals:

  • Share study methodology and engineering results;
  • Discuss the analytical methods and data utilized to assess and map flood hazards associated with Lake Michigan coastal flooding;
  • Provide relevant background to community officials on GLFHM coastal analysis and mapping, so that they can effectively support next steps of the mapping process in their community
  • Engage State and local officials and technical experts in determining the best approach in producing updated flood maps that accurately and precisely reflect flood risk; and
  • Provide the basis for future dialogue between FEMA, state and local communities regarding inputs for study execution, public review of data and results, and opportunities for enhancing community planning processes.

Because local involvement is critical to this process, we are reaching out to local community officials and other stakeholders to provide an opportunity to review and discuss the results of the coastal flood hazard analysis and mapping performed for your county. FEMA is also committed to an open, collaborative process, and your community’s participation in next steps of the project. We have provided information below on the date, time, and location of the meetings. Feel free to forward this information to others who you feel are appropriate to attend these meetings:

Inland Scoping Schedule for Michigan Counties

The Federal Emergency Management Agency (FEMA) conducts scoping meetings to determine the riverine flood mapping update needs. These efforts are combined with the lake-wide coastal flood hazard mapping effort with the outcomes constituting the first basin-wide update of water-level statistics and flood hazard data compiled by the United States government for the Great Lakes in 25 years.

Under these riverine scoping efforts, a key phase in this study process is FEMA’s consultation with local communities through the conduct of a scoping meeting and the collection of data. FEMA uses these scoping meetings and follow-up conversation to collect information that will contribute to a better understanding of local flood risk conditions. A second purpose of this outreach is to provide a venue for sharing information related to study methodology and schedules.

Great Lakes Water Levels Special Report in Milwaukee Journal Sentinel

The Milwaukee Journal Sentinel recently published a very informative and interesting series on Water Levels in the Great Lakes called Uncharted Waters.

Part 1
Does Lake Michigan’s record low mark beginning of new era for Great Lakes?
At least 150 years of rhythmic pulses in Lake Michigan’s water levels appear to have shifted abruptly with loss of winter ice.

Part 2
Water flushes through a greatly widened drain below Lakes Michigan, Huron
Every time dredging widened and deepened the hole at the bottom of the lakes, the federal government was supposed to engineer a fix to maintain water levels – but it never did.
