<br />surface flows, is identified by the branch called "28th Street Overflow" in HEC-RAS. <br />Table 8 summarizes the flow distribution between the culvert and surface flows for the <br />50-, 100-, and 500-year events. <br /> <br />Table 8.

The flow path downstream of the entrance to the <br />28th Street culvert will generally proceed to the south, a portion along the west side of <br />28th Street and a portion along Hazelwood Court west of 28th Street. These flows cross <br />28th Street and re-enter the channel in the vicinity of the intersection of 28th Street and <br />Kalmia A venue. The confluence of the overflow and channel is simulated by Junction 2 <br />in HEC-RAS. <br /> <br />-2] - <br />
