Rural <br />streets that are not upgraded will generally be <br />rehabilitated via a bituminous overlay of 1.5" - 2" subject <br />to the condition of the existing street. <br />B. Storm Sewer <br />Storm sewer improvements are considered to be an integral <br />part of the street reconstruction. The Minnesota Department <br />of Transportation uses a storm frequency of ten years in <br />designing highway drainage systems. The City of Little <br />Canada uses a five year storm for design of storm sewer <br />systems. A storm frequency of 50 or 100 years is used if <br />extensive damage would result from an inadequate storm <br />sewer. A lesser storm frequency may be used for design <br />purposes if an adequate overflow drainageway is present. <br />C.
