A storm drain is defined as that portion of the storm drainage system that receives runoff from inlets and conveys • A higher design frequency (or return interval) should be used for storm drain systems located in a major sag vertical curve to decrease the depth • Drainage - Locate and clearly mark existing drainage swales and patterns on the drawing, including existing storm drainpipe systems.
