ARDEN HILLS PLANNING COMMISSION – November 5, 2014 6 Commissioner Zimmerman requested comment from the applicant on the potential use of pervious pavers in the swale. Mr. Gaybauer understood the merits of using pavers and believed this option would add 30% to the project cost per square foot for the parking surface. He stated this would also modify the storm retention basin. He indicated he would have to more closely review the engineering of the site if the paver option were pursued. Commissioner Bartel was interested in reviewing how the water runoff on the site would be impacted if pavers were used versus not used in the swale. Mr. Gaybauer stated he could investigate this further, while also looking at how the downstream system would be impacted. Commissioner Thompson was in favor of the applicant pursuing pervious options for the parking lot. Commissioner Thompson moved and Commissioner Holewa seconded a motion to recommend approval of Planning Case 14-027 for a Site Plan Review and Variance to reconfigure the existing parking lot at 1160 Grey Fox Road based on the findings of fact and the submitted plans, as amended by the eight (8) conditions in the November 5, 2014, report to the Planning Commission. Condition 8: Approval from the Rice Creek Watershed District. City Planner Streff requested that the Commission address the Findings of Fact to support approval. Chair Larson reported one finding could read: The new retention pond would address the site drainage better than the existing swale, as determined by the City Engineer and Clark Engineering. 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.
