Using MapOffice to View FEMA Documentation


The City of Lake Forest, IL Engineering Department needed a method to quickly look up residential properties that have been granted a FEMA Letter of Map Amendment (LOMA). When a property owner thinks that their property has been incorrectly mapped in a Special Flood Hazard Area, the owner may submit a request to FEMA for a Letter of Map Amendment (LOMA). The granted LOMA will state that an existing structure is on naturally high ground and will not be overcome by a base flood. Acquisition of a LOMA could result in reduced flood insurance premiums. 

FEMA sends copies of the granted LOMAs to the requestor and to the applicable community. These letters are used by the community to ensure floodplain regulation compliance. Previously, the LOMAs were filed and had to be manually referenced and sorted through during the permitting process. To expedite this workflow, the digital LOMAs were all renamed to be indicative of the associated address. Each LOMA address was mapped as a point feature and related to the appropriate document. The locations are now shown in MapOffice as a custom overlay. When a user searches a specified property in MapOffice and selects the location, the LOMA will appear in a new browser tab.  

Enabling users to search and view LOMAs by address in MapOffice saves community staff time and residents can receive a prompt response about floodplain related inquiries. Staff members no longer have to sort through documents to locate the correct file. If a resident is applying for permits where the flooding is of concerns, staff can quickly search an address and determine that a LOMA has been granted.
