The expansion includes a building addition of approximately 10,080 square feet, parking <br />lot improvements, minor storm sewer, and the construction of an infiltration pond. The submittal <br />documents are dated January 28, 2008 and were prepared by Anderson Engineering of <br />Minnesota and NAI Architects. Based upon our review, we have the following comments: <br />Preliminary Site Plan <br />1. Based on the total number of parking shown on the plan an additional handicap stall <br />must be provided to meet current ADA Accessibility guidelines. <br />Preliminary Grading, Drainage, & Erosion Control Plan <br />1. More detail must be provided along the west property line to ensure that the installation <br />of the curb will not cause ponding of water on the adjacent property. <br />2. The Emergency Overflow (EOF) location and elevation for the infiltration pond should be <br />designated on the plan. <br />3. Based on rough scaling of the plan it appears the disturbed area may be over 1-acre in <br />size. The developer should provide a note indicating the total disturbed area on the <br />plan. If over 1 acre is disturbed a Ramsey Washington Metro Watershed District permit <br />will be necessary along with a Minnesota Pollution Control Agency National Pollutant <br />Discharge Elimination System (NPDES) permit and a Storm Water Pollution Prevention <br />Plan (SWPPP). <br />4. An erosion control mat should be provided where the swale south of the building enters <br />the pond to prevent against erosion. <br />Drainage Calculations <br />1. No storm water calculations were provided with this submittal. Prior to final approval, <br />storm water calculations must be reviewed and approved. <br />2. Documentation will need to be provided for the determination of the infiltration rate used <br />for the infiltration pond. The pond must be designed to be dry within 48 hours after a <br />storm event. <br />Z:\PROJ\120109E-Express Image\Itr-020708-PC.doc 14 <br />
