Description: Three to four story mixed use apartment/retail building Stormwater Management: One underground infiltration tank District Rule: —C D F Disturbed Area: 1.29 Acres Impervious Area: 1.16 Acres STAFF RECOMMENDATION: Approve with 8 Conditions: 1. Receipt of $5,800 surety. 2. Receipt of maintenance agreement recorded with Ramsey County. 3. Include a site-specific maintenance plan that includes items a. – e. in the permit report. 4. Provide plans signed by a professional engineer per the Minnesota Board of AELSLAGID. 5. Provide a copy of the NPDES permit. 6. Revise plans to address the items a. – i. in the permit report. 7. Revise HydroCAD to use MSE 24-hr Storm Curve 3 rainfall distribution. 8. Revise drainage area maps and HydroCAD to accurately reflect site conditions. The current drainage areas appear to overestimate how much area drains to the infiltration tank. It is unlikely that all area in proposed drainage area 1 reaches the STRM #5 and #6 and is discharged to the underground infiltration system. Provide additional detail to justify all drainage enters these two catch basins or update drainage area maps and HydroCAD to reflect areas that will sheet flow offsite without treatment.
