It is very important to make sure that the contractor responsible for curb construction understands curb cut designs and elevations. This is often a new technique for contractors and they may not understand the overall concept of water in the gutter line being directed behind the gutter. Common mistakes to avoid:
* Elevated curb cuts and reverse slopes (sloping from back of curb towards instead of depressing from gutter line towards the back)
* Curb cut size (width)
* Placement of curb cuts on steep slopes or the down slope side of a catchbasin
