Proper drainage is a major factor in maintaining good pavement life. No other single factor affects pavement performance more. Known drainage deficiencies are corrected prior to paving roads. Some drainage culverts end up buried over the course of time. If you're aware of such a culvert, please contact the department before your road gets paved. Together we can make the effort successful.
Leaves can block drainage culverts causing road flooding and erosion. Please help us to keep ditches and culverts flowing by not placing raked leaves in drainage ditches.
