Forerunner’s Issues feature provides supplementary EC review and should not fully replace your compliance-checking process. Here are a few items that should be checked manually:
- Correct Diagram Number selection
- Accuracy of CBRS & OPA determination on ECs with an expiration year prior to 2026
- Accuracy of FIRM Index Date
- Presence of Section E, F and G on ECs with an expiration year prior to 2026
- Attachment of Flood Openings Certification, where applicable
- Attachment of V Zone Certification, where applicable
- Amendments made using a Memo of Correction
- Presence of breakaway walls
Understanding issue types
- Errors
- Warnings
Errors indicate issues that must be resolved for the certificate to be valid or compliant. Common causes include:
- Missing required fields
- Data that contradicts FEMA records
- Elevation measurements that don’t match the building diagram type
- Buildings below the required flood elevation
