Preliminary & Effective Maps
If your community has a Preliminary FIRM, chances are you are looking at it frequently as a regulatory tool, to understand potential shifts to your community's risk distribution, or to inform residents of future changes. We've added Preliminary FIRMs to our mapping feature so that you can now view both Preliminary FIRMs as well as Effective FIRMs in the same place.
For those communities that do not have an active Preliminary FIRM, only Effective FIRM information will show. Preliminary FIRM information is retrieved directly from FEMA's map service, so FIRM maps will automatically update when changes are made in FEMA's database.
You can find Preliminary FIRM information in both the Map and the Property Info Panel:
In the Map
FIRM information in the Map is now divided into two layers:
Effective FIRM and
Preliminary FIRM. You can toggle between these map layers using the Map Panel (more on this below). To switch between FIRM versions in the Map Panel, click the toggle button to the right of
Effective FIRM or
In the Property Info Panel
When you search for an address in the Address Search Bar, the Property Info Panel will display. It will also display if you click on an Elevation Certificate instance in the Map. The Panel is divided into two sections:
FIRM Map Info and
Permits. Within the
FIRM Map Info section,
Preliminary FIRM and
Effective FIRM information is displayed in two columns, side by side.
New Map Sub-Layers
We've also added two new sublayers to the map. Sublayers are nested within Layers. Unlike Layers, they cannot be toggled on or off — their visibility is controlled by the Layers they are nested in. New sublayers include:
Floodway - The Floodway sublayer depicts the Regulatory Floodway in your community. This sublayer can be used to check compliance with your community's development guidelines. It is depicted as a hatched overlay on the map.
LiMWA - The Limit of Moderate Wave Action (LiMWA) is defined by FEMA as "…the inland limit of the area expected to receive 1.5-foot or greater breaking waves during the 1-percent annual chance flood event." It is displayed as a black patterned line on the map.
Map User Interface Changes
To accommodate future features and increase usability, we've made some organizational changes to the Map feature.
The map panel contains layer keys and visibility toggles. To locate this panel, click the map layers icon in the bottom right corner of your Map. It is positioned above the Map's zoom buttons. As noted above, FIRM zones, floodway information, and LiMWA information, are nested within FIRM layers. When either the
Effective FIRM or
Preliminary FIRM are toggled on, all zone, floodway, and LiMWA information will display for that FIRM version.
Address Search Bar
The Address Search Bar is now located in the top left corner of your map. To find information for a specific property, type the address in the Address Search Bar. You can either click one of the autocomplete selections or press enter once you've typed your address to display the Property Info Panel. As before, the map will zoom to the searched address and a blue location marker will be placed on the property.
Property Info Panel
The Property Info Panel can be displayed using the Address Search Bar or by clicking on an Elevation Certificate instance on the Map. Information on the Property Info Panel is divided into two sections:
FIRM Map Info and
FIRM Map Info - If your community has both an Effective map and a Preliminary map, the
FIRM Map Info section will provide data for both versions. If your community has only an Effective map and no Preliminary map, only Effective map data will be provided. A new data row has also been added to this section.
BFE Depth is now provided for AO Zones. Where no data is provided by FEMA's map service, a dash (-) will appear in lieu of information.
Permits - If the property searched has an Elevation Certificate associated with it, it will appear under
Permits. If no Certificates are available, the Permits section will read:
No permits found. Elevation Certificates can also be found in the
Certificates section of your app, which can be located by clicking on
Certificates in the dark blue sidebar.
Base maps are now cropped by community jurisdictional boundary so that you will only see applicable map information for your own community.
