Ms. Katie Larsen <br />05/07/2025 <br />Page 5 <br />Java Properties - Lino Retail 2.0 Engineering Review <br />(WSB 5/7/2025) Comments remain from Lino Lakes 2.0 1st Addition <br /> <br /> <br />11. The Marketplace Drive roadway and existing stormwater basin, including offsite <br />tributary drainage, must be included in the HydroCAD model to understand all flows <br />throughout the site. <br />(DTE 3/11/2025) The Marketplace Drive roadway and existing stormwater basin have <br />not been included in the HydroCAD model as there is no interaction between the City <br />and Development’s stormwater infrastructure. <br />(WSB 4/2/2025) Complete <br /> <br />12. HydroCAD runoff should be set to “Calculate separate pervious/impervious runoff <br />(SBUH weighting)” for most accurate runoff results. <br />(DTE 3/11/2025) The HydroCAD model has been updated per the comment. <br />(WSB 4/2/2025) Complete <br /> <br />13. Proposed impervious should be entered as paved parking and roof as there is a mix <br />of both. <br />(DTE 3/11/2025) The HydroCAD model has been updated per the comment. <br />(WSB 4/2/2025) Complete <br /> <br />14. Existing and proposed models should route to a Link node to calculate total offsite <br />flows. <br />(DTE 3/11/2025) The HydroCAD model has been updated to include one discharge <br />node for both existing and proposed conditions <br />(WSB 4/2/2025) Complete <br /> <br />15. Confirm drainage area delineations match site grading, some areas on the perimeter <br />of the sites do not appear possible to route to proposed stormwater basins as <br />indicated in HydroCAD. <br />(DTE 3/11/2025) The drainage areas have been updated per the comment. <br />(WSB 4/2/2025) The existing modeled drainage area of 4.551 acres exceeds the <br />proposed modeled drainage area of 4.071 acres. These areas must match for proper <br />confirmation of rate control. <br />(WSB 5/7/2025) Comments remain from Lino Lakes 2.0 1st Addition <br /> <br /> <br />16. For modeling of outflow rates and HWLs, exfiltration is not allowed in HydroCAD to <br />conservatively design assuming basin infiltration capacity is lost in the future. <br />(DTE 3/11/2025) Infiltration has been removed from the HydroCAD model per the <br />comment <br />(WSB 4/2/2025) Complete <br /> <br />17. (WSB 4/2/2025) It is recommended to consolidate the parking space curb cuts going <br />into IB-1. <br />(WSB 5/7/2025) Comments remain from Lino Lakes 2.0 1st Addition <br /> <br />18. (WSB 4/2/2025) The IB-1 storage curve in the HydroCAD modeling is incorrect for <br />the 906 contour. <br />(WSB 5/7/2025) Comments remain from Lino Lakes 2.0 1st Addition <br /> <br /> <br />Page 254 of 353
