Crossing Information*
Type of Crossing: Culvert(s)
Number of Structures: 1
Structure Shape: Round
Inlet Type: Projecting
Outlet Type: At Stream Grade
Structure Material: Concrete
Structure Substrate: Mixture
General Conditions: Severe deterioration from corrosion or abrasion (more than 50% of the structure is rusted through) or cracking or spalling or chipping (more than 50% of the structure is compromised). Or Major shape changes (described above) reducing the capacity of the structure by greater than 50%. OR Segment disconnect causing major subsurface erosion/piping and/or partial fill failure and/or sink holes in the fill.
Structure Interior: Smooth
Is Structure Rusted through? No
Dimensions of Structure: Length 24 ft. Width 2 ft. Height 2 ft.
Percentage Plugged: 81% - 100% Inlet
Percentage Crushed: 1% - 20%
Structure is NOT Perched
Structure Inlet
Water Depth: 0.1 ft.
Embedded Depth of Structure: 0.5 ft.
Water Velocity*: 0 ft./sec.
Structure Outlet

*Water Velocities were measured at the surface (via Float Test).
Stream Information
Stream Flow: None – The streambed is dry and there is no water flow.
Stream Flow Type: Intermittent (if channel is dry but has obviously flowed recently, appears to flow annually).
