Properties, which benefit directly or indirectly from the City's Storm Water Management System are subject to stormwater utility charges. For more information, call 343-4777. A cave-in appears as a hole in the ground, pavement, etc., or can cause cracks or breaks in concrete driveways, sidewalk or any area above an underground utility. They occur when either pipe, pipe joints or structures fail.
Structures are manholes, catch basins, junction boxes, etc.
The actual hole is created as soil washes, leaks or is pulled into an underground system. They can occur gradually, or immediately depending on other factors that can sometimes form under the surfaces and not break until there is sufficient weight to cause the surface material to give way. However, the actual repair time varies depending on location, traffic, weather and other factors.
