(c) Street storm sewers shall be designed for a ten-year design storm. Storm water management and erosion control for the entire development shall be provided in accordance with Chapter 961. Minimum storm sewer size shall be twelve inch.
(d) Storm sewers shall be constructed at a depth sufficient to serve all the area within the watershed which may drain through the area being developed and deep enough to allow for construction of water mains and sanitary sewers.
(e) Manholes shall be constructed at the junction of two or more sewers at the termini, at all changes in size, alignment, and grade, and at a distance not to exceed 400 feet. For storm sewers 42 inches in diameter and larger, spacing may be increased to 500 feet.
(f) Catch basins shall be constructed on the upstream side of the crosswalks, at all low points in the street, at points where drainage ditches enter the area being developed, at intersections, and on streets at distances not to exceed 400 feet.
