Regular City Council Meeting Monday, September 12, 2016 Page 28 the newly created drainage. He stated City Code 1017 does not prefer storage bins, like the Aqua blocks, but that is an option so you can construct a pervious driveway for all of the drainage and then use that water for irrigation. Mayor Roe asked if this is very conceptual from that point of view. Mr. Koland answered in the affirmative and explained he had just offered ideas of how he could easily accommodate the requirement to impound all water from additional development and then it could be taken through negotiations if to the point of de- velopment. Mayor Roe thanked Mr. Koland for that clarification. Councilmember Laliberte asked if this subdivision is approved, will the new own- er of the subdivided property be held to this grading plan and not necessarily Mr. Koland since it will no longer be his property. Mr. Culver explained the owner of the property where the basins are placed will be responsible for installation, maintenance, inspection, and recertification every five years. Councilmember Laliberte stated how the subdivided lot will be flagged to alert staff when a grad- ing application comes in. Mr. Culver stated there are ways to place such an alert within the City’s record keeping system. Councilmember Laliberte asked whether, with the recommended actions, Condi- tions a-d, and what has been conceptually offered, staff supports statements pro- vided by Mr. Koland that this subdivision proposal retains all additional run off and eliminates any potential for injury to his neighbors. Mr. Culver stated that in- volves some very broad statements and whether or not it addresses all of the run- off from the site will depend on the design of the BMPs and on the size of the rain event. He stated it will be able to handle all of the run off from a certain size event but at some point, for a very large rain event, it will not be able to handle all of the run off. He stated the City has standards to design for certain rain events and the intent is to address rate control to slow the water before entering the storm water system for those rain events. Councilmember Laliberte stated the rain events the City has been experiencing are not typical of rain events when past subdivisions were granted approval in this area by previous Councils. She asked staff if the 2-year, 10-year, and 100-year thresholds are still the correct ones to be evaluating. Mr. Culver stated that is a topic for a much larger debate. He stated the City does have updated rainfall standards through Atlas 14 that were studied a few years ago and adopted by a lot of Watersheds. The City of Roseville adopted those new standards as well. Mr. Culver explained that is not to say that in five years, those will remain the current standards but given the current data and studies, that is what the City designs for. Etten moved, Willmus seconded, approval of the minor subdivision of 1926 Gluek Lane into two parcels, based on the comments and findings of the RCA dated September 12, 2016, and subject to conditions, a-d, as outlined in said RCA.
