The velocity of flow on an open ditch shall not exceed four feet per second in soil ditches or six feet per second in turf gutters. Paved gutters will be required if velocities of flow are greater than those specified, or if it is likely otherwise that destructive erosion will result. Drainage ditches shall not be permitted to discharge into any sanitary sewer facility. Retaining basins shall be designed in accordance with Standard Design Practice.
