Materials <br />used should be checked for conformance with the specifications. Inlet protection should be used around all <br />susceptible inlets on site. <br /> <br />Maintenance <br /> <br />After every rainfall that produces runoff, storm sewer inlet protection must be inspected. <br /> <br />Sediment should be removed as needed. Excavated sediment should be placed where it will not create an <br />erosion problem. Ponding water should slowly draw down following a rainfall. Geotextites, rock, and perfo- <br />rated pipes used for inlet protection can easily become plugged with sediment and prevent draw down. <br />Geotextiles and rock should be cleaned or better yet, replaced. Pip perforations should be cleaned. <br /> <br />Inlet protection should be removed as soon as the contributing drainage area is stabilized. <br /> <br />Periodic inspection and maintenance of inlet protection systems is critical Maintenance include removing <br />sediment and replacing stones. <br /> <br />Sources <br /> <br />I.
