ARDEN HILLS PLANNING COMMISSION – November 5, 2014 7 Commissioner Holewa was in favor of tabling action on this item to allow the applicant to review the potential use of pavers, in addition to how this will impact the water runoff. Commissioner Zimmerman stated the site was currently maxed out on impervious surface. He feared how the site would be impacted by the proposed request and for this reason he could not support the Planning Case. Commissioner Bartel agreed and requested the applicant further quantify the amount of additional water that would be running off the site. He recommended the Planning Case be tabled until this information could be brought back to the Commission. Chair Larson believed that the information provided by the engineer was sufficient and proved that the proposed retention pond was an improvement over the current swale. Commissioner Zimmerman wanted to see the City be sensitive to the amount of storm water runoff coming from this site given the recent fines the Met Council has assessed to cities in the metro area. Chair Larson still believed the trade off and improvement to the storm sewer system merited approval. The motion failed 3-3 (Bartel, Holewa and Zimmerman opposed). Commissioner Holewa moved and Commissioner Zimmerman seconded a motion to table Planning Case 14-028 a Site Plan Review and Variance at 1160 Grey Fox Road to allow the applicant to review the request further with staff. Commissioner Holewa requested comment from the City Engineer on the runoff and proposed infiltration basins. Commissioner Bartel also wanted to see a comparison on the storm water system both for the current system and proposed system. Commissioner Zimmerman wanted to ensure that the new storm water system would handle the additional runoff. He did not support any increase in impervious surface and recommended the applicant further investigate the use of pervious pavers or concrete. Chair Larson reiterated that the applicant had already received conditional approval from the Rice Creek Watershed District. He explained that the new retention pond and filtration basin would manage the water runoff differently than the current swale. The motion failed 3-3 (Chair Larson, Jones and Thompson opposed). Commissioner Bartel did not understand why the Commission did not fully support the request being tabled. Commissioner Thompson did not believe the matter had to be tabled as the Commission had enough information to recommend approval.
