HydInfra Share Ideas

Flowchart - Suggested Repair Method for Highway Culverts (PDF) has been updated in 2020 to change the focus from Statewide or District repair estimates to more detailed suggestions for repairs of individual pipes. District Maintenance groups can select pipe repairs to done from a report based on the Flowchart sorting process.. The report uses an ArcGIS model to select pipe repairs from spatial data and exports the report. Statewide, Maintenance has adopted a new Drainage Measure for Highway Culvert Repairs (culverts under highway traffic lanes).
