6. The response is inadequate. While Table 1 is very useful, it contains some minor <br />errors that should be corrected. For Structure 3, the area is mislabeled as A38a rather <br />than A38; for Structure 30, Area A27a has an incorrect CN value; for Structure 21, the <br />area is mislabeled as AS17 rather than A17; and for Structure 11, the Name is <br />mislabeled as RD2 rather than RD1. <br />Also, the table facilitated a more detailed review of the SEDCAD model, and a <br />possible error was detected; it appears that the areas and curve numbers for Structure <br />10 (the Collom Sump) may not be correct. Area A6 appears to be much larger on the <br />map (Figure Al in Exhibit 7, Item 23) than 14.7 acres, and it contains an undisturbed <br />portion, which does not appear in the model input table. Also, it appears that Sub - <br />watershed #1 for Structure 10 should have a CN of 85, based on the map. Please <br />review the model and revise as necessary. <br />11. The response is adequate. <br />13. The response is inadequate. The Area - Capacity table still does not match the <br />Elevation- Capacity- Discharge table in the SEDCAD printout in Exhibit 7, Item 23. <br />Rule 4.05.7 Discharge Structures <br />1. The response is inadequate. Please indicate where SEDCAD inputs and results are <br />presented for the LCWD outlet apron. <br />Rule 4.05.13 Surface Water and Groundwater Monitoring <br />See Tom Kaldenbach response. <br />3 <br />
