§42-100.
Road Drainage and Culverts
Road drainage structures, ditches, and culverts shall be designed and constructed in accordance with State Road
Standards and with sufficient depth and width to carry the expected volume of stormwater runoff. Culverts may be
required where the road crosses streams or minor watercourses. Best Management Practices should be utilized for
road swales (turf matting and vegetation, etc.) to control erosion and transport of sediment and to filter pollutants
from stormwater runoff.
