Final 2010 CEA Maps

View and Download Online Maps Using
the Internet Mapping Service (IMS)


Step 1: Entering the IMS

Review the Disclaimer page and accept the Terms by clicking the “Accept” button at the bottom of the page.

The map is set to refresh automatically every time you select a new feature. To disable this function and manually refresh the map, uncheck the “Auto Refresh” box in the right column of the webpage, under the red “Refresh Map” button. Then, to refresh the map at anytime, click the “Refresh Map” button.

When the map opens, you may wish to maximize the window to allow for full-screen viewing of the entire page. 

Go to the IMS tool.

Step 2: Zooming In and Out and Panning

Zoom into the area of interest using either (1) the ”Zoom to County” pull-down list or (2) the “Zoom In” tool.

Click the arrow next to the ”Zoom to County” pull-down in the upper left corner of the IMS screen and select your area of interest from the list of Lake Erie counties and Islands. The screen will automatically zoom in to the scale for the county or islands you select.

To zoom in, click the “Zoom In” tool button on the left side of the screen. Move the cursor to the corner of an area that you intend to zoom into. Click and hold the left mouse button while dragging a red box to the opposite corner, then release the mouse button to zoom in. Notice the red box outline you’ve drawn. The larger dimension, either North-to-South or East-to-West, will fill the map frame window.

The “Zoom Out” tool works in a similar yet opposite manner.

Continue zooming in to the area of interest by using road intersections and city/village names to locate your place of interest. Please note that as you continue to zoom in, you will see road names and map frame numbers appear.

While zooming in, you can use the “Pan” tool to recenter or move to a different place on the map while maintaining the same scale. Click the “Pan” button in the left column. In the map window, click and hold the left mouse button while dragging the cursor (and the map image) to the area you wish to see. Then release the button to redraw the map.

Step 3: Viewing the CEA Map (PDF)

Once you have found your area of interest, view the CEA map by clicking the “View Map [PDF]” button in the left column to activate the tool. Then, in the map frame, click on one of the CEA Mapbook Page Index boxes (in red) located along the lake margin. This will open a new window that features the map and associated data tables as a multi-page PDF file.

Note: you will need the free Adobe Reader software to view these files. Some files are larger than others and may require longer download times.

Note that each rectangle is labeled with its Frame Identification number. The rectangles will overlap to ensure each map has complete coverage. Thus your property may be represented in more than one map frame. Select the map frame where you believe your property is most centrally located. Please make note of this map frame number for future reference and for cross-checking the data table.

Step 4: Printing and Saving CEA Maps

You can either save or print the PDF maps. The printed maps are designed to be printed on 11- x 17-inch (tabloid) paper, but the “Fit to Page” function within Adobe Acrobat will allow you to print to a smaller paper size. However, this option will reduce the quality and scale of the map, so this is not recommended. You can also save these maps to your local computer hard drive by choosing the “Save As” button in Adobe Acrobat Reader, or by clicking on the small disk icon in the upper left of your screen if you are viewing the map inside your web browser.

Go to the IMS tool.


Background Information on CEA Mapping

To date, two editions of CEA maps and data have been issued. Some public viewing locations may still have copies of the final 1998 CEA maps and data (with blue covers and black-and-white maps), but these are no longer in effect for regulatory purposes. The finalized 2010 CEA maps and data supersede all previous editions. They are viewable online or in hardcopy at local agencies.

For local agency locations with printed paper maps, CLICK HERE, or, download a list of ALL locations as a single PDF file.

For how to read the CEA maps, CLICK HERE.

For additional information on Ohio’s CEA Program and what a CEA designation means for a property, please download the fact sheet Fact Sheet on Finalized 2010 Coastal Erosion Area Maps.
