The value obtained for total inlet width can then be divided by a chosen number of inlets to determine the required width of each curb cut inlet. Curb cut inlets draining roadways should be a minimum of 0.45 m in width and are typically no wider than 2 m.
The value obtained for total inlet width can then be divided by a chosen number of inlets to determine the required width of each curb cut inlet. Curb cut inlets draining roadways should be a minimum of 0.45 m in width and are typically no wider than 1.5 m.
Where the curb cut width is constrained and a greater flow into the BMP is desired, the effective cross slope (''S<sub>x</sub>'') may be increased by adding a depressed concrete apron.
