Provide Emergency Overflow (EOF) elevations for all low points in the parking or <br />green space areas. <br /> (DTE 3/11/2025) EOF locations have been called out on the plans <br />(WSB 4/2/2025) Complete <br /> <br />7. (WSB 4/2/2025) Check with Anoka County to see whether connecting to the existing <br />storm sewer on Lake Drive without crossing Market Place Drive is possible from <br />infiltration basin IB-1 (assumed INV 906.09) <br />(WSB 5/7/2025) Comments remain from Lino Lakes 2.0 1st Addition <br /> <br />8. (WSB 4/2/2025) The spot elevations of the proposed entrances behind the curbline <br />differ from the spot elevations on the City plans. Coordinate what elevations will be <br />necessary beyond the sidewalk and apron. <br />(WSB 5/7/2025) Comments remain from Lino Lakes 2.0 1st Addition <br /> <br /> <br />• Stormwater Management <br /> <br />Stormwater management for the Lino Retail 2.0 site consists of infiltration basins for the <br />southern and northern lots. Additionally, some stormwater infrastructure is proposed for the <br />City realignment of Marketplace Drive. Existing and proposed discharge rates are <br />summarized below. <br /> <br />Pre- and Post- Development Discharge Rates (cfs) <br />Condition 2-Year 10-Year 100-Year 10-Day Snowmelt <br />Existing 2.37 5.53 14.27 Needed if basins <br />landlocked <br />Currently <br />Proposed 1.65 4.77 10.86 Needed if basins <br />landlocked <br /> <br /> <br />Comments: <br />1. An approximate City storm sewer alignment is marked up on the plans showing the <br />pipe intended to provide an outflow for the site rather than emergency overflows. The <br />northern infiltration basin shall outlet into the pipe. <br />(DTE 3/11/2025) The plans have been revised with the updated City storm sewer <br />design <br />(WSB 4/2/2025) Complete <br /> <br />2. Remove the City infiltration basin between the roadway and parking lot, the basin <br />west of the driveway access will provide sufficient storage for runoff. <br />(DTE 3/11/2025) This basin has been removed <br />(WSB 4/2/2025) Complete <br /> <br />3. Provide an equalization pipe or channel between the existing City stormwater basin <br />and proposed infiltration basin at the 100-yr HWL (906.3). <br />(DTE 3/11/2025) The plans have been revised to eliminate interaction between the <br />City and Development’s stormwater infrastructure. <br />Page 252 of 353
