EC Error Detection Issues Guide

This issues guide documents the logic that Forerunner uses to surface issues with our Elevation Certificate (EC) Error Detection feature.

Because the structures of the forms vary, this issues guide is divided into:

Errors and warnings for 2026 Elevation Certificate version
Errors and warnings for pre-2026 Elevation Certificate versions

The two tables are divided into Elevation Certificate sections and columns are defined as follows:

EC Field: The Elevation Certificate field that the issue is associated with.
Issue Trigger: The trigger used to signal an issue flag.
Type: The Type of Issue. Warnings are typically informational while Errors are potential errors in the completion of the EC.
Issue Note: The text that you see when an issue is triggered, describing the issue.

Note: 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:

Accuracy of Latitude & Longitude coordinates
Inclusion of at least 2 photographs
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 surveyor, engineer, or architect stamp & signature
Accuracy of Sections F and G
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

While Forerunner does not warrant any of the issues flagged by our EC Error Detection feature, we strive to be as accurate and transparent as possible in its development. If you have any questions, or if you have a suggested addition to this list, please don't hesitate to reach out to us at support@withforerunner.com.
