Lines created by the ArcHydro tools to Identify Breach Areas and Create Breach Lines. The Breach lines are then selected where they are near a county road, and the county roads are joined to the lines to attribute them with a road name they may cross. The breach lines are then renamed to CulvertChecks and added to the enterprise geodatabase that is used for all web and mobile app data storage.
