<br />SWMP is updated with wetland summary bounce and inundation requirements. <br />10. The applicant shall refer to Table C5 in RCWD Rule C for soil infiltration rates. <br />Comment Noted <br />Applicant shall update infiltration rate in HydroCAD model for IB10 to be <br />consistent with soil boring and Table C5. <br />Soil boring SB-2 was placed in the infiltration area. The soil was described as silty <br />sand overlying coarse-grained sand. This is consistent with an infiltration rate of 0.45. <br />11.The applicant shall update wa ter quality standards to be consistent with the <br />requirement to treat 1.1-inches of runoff for new or reconstructed impervious surface <br />per section 6c of RCWD Rule C. See Table C1 in RCWD Rule C for the TP removal <br />factor for stormwater ponds and apply as necessary. The applicant shall verify that <br />the site is meeting water quality treatment standards. Meeting the standards is not <br />feasible on this site due to the high water table. <br />The applicant needs to meet water quality standards for the site. Please update <br />Appendix C to account for the TP removal factor indicated for stormwater <br />ponds (Table C1 in RCWD Rule C or Table 2 in Lino Lakes Code of <br />Ordinances Chapter 1011). The applicant shall consider including a water <br />quality discussion in Section 2 of the Stormwater Management Plan. <br /> <br />Updated TP removals will be included in the updated SWMP <br /> <br />Updated TP not included in the revised Appendix C. Per RCWD CAPROC, water <br />quality requirements are being met. It is recommended that applicant include a <br />water quality discussion in section 2. <br />RCWD has approved this plan. Please verify that the city will require this. All <br />ponds are designed to NURP standards. All ponds, basin expansions, the addition <br />of infiltration, and enhancement of wetlands should cover TP requirements. Very <br />little water is running directly offsite. The majority of the site is running through <br />at least two of these (if not more) storm water practices. <br />Total required water quality treatment removal for the 8.7 acres of impervious surface <br />is being met by volume reduction and NURP ponds. Calculations are found in <br />Appendix C of the SWMP. <br />12.The applicant shall verify HWLs for ponds. In some instances, they differ betwee n <br />the HydroCAD modeling and the plans. HW Ls confirmed. <br />The applicant shall revise the HWLs on the plans to match HydroCAD <br />modeling. <br />Plans are updated. <br />Applicant shall clarify why two different 100-yr HWL and 10-day Snowmelt <br />elevations are shown on the plans. <br />Smaller text shows HydroCAD water levels. Larger text shows water levels provided <br />by RCWD. Both are shown to compare the two. <br />13.The applicant shall clarify the intent of the low area on Outlot D. If intended to be <br />a stormwater pond, please include it in modeling. Node added <br />14.The applicant shall revise the ACD number it varies throughout the Stormwater <br />Management Plan and SWPPP narratives. Comment Noted and ditch ID consistent <br />in report
