DRMS Comment <br />Map G -1B: <br />2. Channel COLL A appears to be intended to route runoff from SWB -6A to the upper <br />segment of channel COLL #1. <br />a. The peak flow shown on the drawing and calculated in Appendix 6 is 4.36 cfs. <br />The peak flow from SWB -6C is only 2.06 cfs. The drawing should show <br />cumulative peak flow values for the purpose of hydraulic design analyses. Please <br />provide clarification and/or corrections as necessary to the drawing and hydraulic <br />designs to account for runoff from SWB- 6A/COLL A adjacent to SWB -6C. <br />b. Similar to Comment 2a, if COLL A is routed to COLL #1, please provide <br />clarification and/or corrections as necessary to the drawing and hydraulic designs <br />to account for runoff from SWB- 6A/COLL A and SWB -6C in the COLL #1 <br />segment adjacent to SWB -6D. <br />3. Channel COLL B appears to be intended to route runoff from SWB -6B to the upper <br />segment of channel COLL #2. The peak flow shown on the drawing and calculated in <br />Appendix 6 is 6.4 cfs. The peak flow from SWB -6E is only 1.62 cfs. The drawing <br />should show cumulative peak flow values for the purpose of hydraulic design analyses. <br />Please provide clarification and/or corrections as necessary to the drawing and hydraulic <br />designs to account for runoff from SWB -6B /COLL B adjacent to SWB -6E. <br />4. The runoff listed on the drawing for SWB -6F is 1.32 cfs. The calculated runoff <br />Appendix 6 is 1.24 cfs. Please correct the flow presented on the drawing. <br />5. Channel COLL #3, similar to Comments 2 and 3, please confirm or make necessary <br />corrections to the drawing and hydraulic design calculations to ensure the cumulative <br />runoff is considered in the design of COLL #3 for segments adjacent to SWB -7A, SWB- <br />7B, and SWB -7C. <br />6. The runoff listed on the drawing for SWB -7B is 3.07 cfs. The calculated runoff <br />Appendix 6 is 2.49 cfs. Please correct the flow while considering Comment #5. <br />7. The runoff listed on the drawing for SWB -7D is 2.18 cfs. The calculated runoff <br />Appendix 6 is 4.79 cfs. Please correct the flow presented on the drawing. <br />SMO Response <br />The Map G -1B has been revised to accurately match the stormwater basin (SWB) values in <br />Appendix 6. Additionally, the segments for each ditch are shown on Map G -1B to match the <br />profiles on Map G -5. Map G -5 has also been revised to correctly show the surface runoff <br />requirements for each segment (ex: Coll #1 Segments 1 & 2 show the combined SWB -6A and <br />6B flow requirements) <br />
