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.<br> '''Construction Steps:'''#Place the right forms (rolled curve vs standard) in the inlet location.#Pour concrete.#Shape the inlet #Add the river stone on top of the fresh concrete (if applicable) #Provide sufficient curing time, according to CSA standard A23.1-09.[[File:20150618 114542.jpg|thumb|500px|right|Caption]][[File:P1160129.JPG|thumb|400px|right|Caption]]'''Key Inspection Points:''' *Use of proper curb form by sub-contractor.*Curb type aligns with design.*Curb cut location, type and dimension aligns with design.*Designated concrete wash out is in place and away from LID facility.'''Mistakes to Avoid:<br>'''*Elevated curb cuts and reverse slopes (sloping from back of curb towards instead of depressing from gutter line towards the back).*Wrong curb cut width size. *Use of wrong curb form. *Concrete wash out within or upstream of LID facility.*Ensure curb granular base (granular A) does not spill over into LID infiltration area. If material spills over, remove as best as possible while still maintaining the 2:1 slope for curbing*Lack of communication to concrete contractor or ready-mix driver explaining the function and importance of protecting the LID feature.For more information on curb cuts, see these pages: [[Curb cuts]], [[Curb cuts: Gallery]] and [[Bioretention: Streetscapes]]<br>
