Abstract: A device for restricting flow through a curb inlet opening defined in a street storm drain by secure positioning a face plate extending thereover. Multiple flow slots are defined extending through the face plate to allow limited flow therethrough. The face plate is securable to the drain by mounting apparatus which includes one or more mounting brackets along with an engagement device attachable to the flow limiting slots and the brackets to hold the face plate in position extending over the curb inlet opening. Mounting brackets can have teeth for engaging storm drain for enhanced securement therewith. The flow restricting slots are preferably radially arranged with respect to one another and can include lateral slots further engageable with the mounting bracket to prevent rotation thereof during tightening thereof. Conical washers can extend over the head of mounting bolts for protection thereof.
