Inlets are further classified as being on a <br />"continuous grade" or in a sump condition. The term continuous <br />grade refers to an inlet so located that the grade of the street <br />has a continuous slope past the inlet and, therefore, ponding does <br />not occur at the inlet. The sump condition exists whenever water <br />ponds because the inlet is located at a low point. A sump <br />condition can occur at a change in grade of the street from <br />negative to positive, or at an intersection due to the crown slope <br />of a cross street. <br /> <br />Presented in this section is the criteria and methodology for <br />design and evaluation of storm sewer inlets in the City. Except as <br />modified herein, all storm sewer inlet criteria shall be in <br />accordance with the USDCM. <br /> <br />7.2 Standard Inlets <br /> <br />The standard inlets permitted for use in the City are: <br /> <br /> <br />.
