Properties with roadside swales often have driveway culverts and pipes that convey stormwater under the driveway apron within the right-of-way to channel runoff. Maintenance of these pipes and adjacent areas is generally the property owner's responsibility.
We recommend that homeowners inspect and clean driveway culverts regularly: quarterly or more frequently. We you to check your pipe before big storms, when you witness standing water in the swale, or the pipe is 20% or more full of sediment.
