• Segment RSSC040B from node 72006 to 72007 was updated with a new length, invert,
<br />and rim elevations obtained from the new survey data.
<br />• Model segment RSSC100B from node 72002 to 72770 was divided into 3 segments to
<br />incorporate a culvert not included in the original model. The new segment names are
<br />RSSC100B, RSSC100C, and RSSC100D.

<br />•
<br />Anew segment RSWO140 from node 77703 to 58311 was added to the model to extend
<br />the model farther upstream to incorporate a 54 -inch pipe segment upstream of node
<br />58311 that was not included in the original model.
<br />• Node 58289 was renamed to 58310 to match the node number from the survey data and
<br />the GIS layer.
<br />• Data for segments RSWO110A, RSWO110B, RSWO110C, RSWO040C, RSWO090B,
<br />RSWO090C, RSWO090D, RSWO090E, RSWO090F, RSWO090G, RSWO090H,
<br />RSWO080A, were updated according to survey information related to lengths and
<br />elevations.
<br />• Segment RSWO090A was divided into 2 segments, segment RSWO090A and
<br />RSWO090Aa, since new survey data was collected for these segments individually.
<br />• Segments RSWO070E, RSWO070F, RSWO070G, and RSWO070H were renamed to
<br />RSWO070B, RSWO070C, RSWO070D, and RSWO070E respectively because old
<br />segment names RSWO070A, RSWO070B, RSWO070C, and RSWO070D were
<br />combined into one segment (RSWO070A) in the new survey data. These segments were
<br />updated with new invert elevation and cross - section information obtained from new
<br />survey data.
<br />• Segments RSWO060B, RSWO060A, RSWO050C, RSWO050B, RSWO050A, and
<br />RSWO040C were updated based on new survey information for lengths and elevations.
<br />A -1 Channel Subbasin
<br />• Segments RSA1100L, RSA1100K, RSA1100G, RSA1100F, RSA1100E, RSA1100D,
<br />RSA1100C, RSA1100B, RSA1100A, RSA1090G, RSA1090F, RSA1090E, RSA1090D,
<br />RSA1090C, RSA1090B, RSA1090A, RSA1080B, RSA1080A, RSA1060U, RSA1060J,
<br />RSA1060I, RSA1060H, RSA1060G, RSA1060C, RSA1010A, RSA1030B, RSAl230A,
<br />RSA1160F, RSA1160E, RSA1160D, RSA1160C, RSA1160B, RSA1160A, RSA1150B
<br />were updated based on survey information for lengths and elevations.
<br />• Segment RSA1060S from node 71209 to 71210 was divided into 2 segments to
<br />incorporate a 36x72 -inch CMP culvert that was included in the new survey but not
<br />2
