Article II. DRAINAGE FACILITIES |
§ 14-27. Hydraulics of minor streams, canals, ditches and swales.
Open channels other than major waterways may be defined as minor streams, canals, lakes, ditches and swales. Such open channels shall be designed in accordance with good accepted engineering practice adapted to county conditions. The design shall provide that the channels will not overflow their banks at design flood conditions. Cross-sectional areas and hydraulic gradients shall be such that design velocities shall not result in soil scouring for the soil and/or turf conditions reasonable anticipated. Mean velocities greater than three feet per second shall be considered excessive unless permanent channel lining or other suitable protection is employed.
