Field Notes: Catawba Hospital Ford Crossing

By Chad Austin, Water Quality Engineer, Western Region

Members of the western region and water quality team recently installed a GeoWeb ford stream crossing on the Catawba Hospital grounds in Roanoke County. The ford crossing was installed using State Lands funds from a timber sale being conducted by the agency on the hospital’s property. This crossing replaces an extremely undersized culvert crossing that has been a maintenance issue for many years and is in a state of disrepair.

Old culvert in disrepair

Ford crossings, where applicable, are one of the most preferred low-cost alternatives to culvert crossings. Ford and bridge crossings are a preferred option in watersheds where land-use change and impervious surfaces like roads and parking lots make flash flooding and runoff an issue. Preferred sites for fords often include streams with large watersheds where pipe sizing and bridge crossings are impractical due to stream bank widths, and where low, wide banks are conducive to vehicle traffic.

The new crossing installation at the hospital will be used to educate loggers and landowners who are considering the installation of GeoWeb ford crossings. It was created with the intention of incorporating it into SHARP Logger trainings and landowner educational opportunities. DOF specialists and field personnel were able to see the various processes and challenges that operators encounter when considering stream crossing options. This experience will aid field staff in making sound water quality recommendations and suggestions in the future.
