result in the same or lesser than the existing conditions. He stated that the design that does not address a 100-year event would not be approved by the WMO. Councilmember Woestehoff asked when the LRRWMO would be reviewing the case. City Engineer Westby stated that it is his understanding that the developer intends to submit to the LRRWMO in July for review at its August meeting. Commissioner Hunt asked if those meetings are open to public comments. He noted that perhaps residents with concerns about drainage should bring those concerns to the WMO. City Engineer Westby confirmed that those meetings are also open to the public and provided details on where those meetings dates and packets can be found. Councilmember Woestehoff stated that the WMO is a multi jurisdictional organization and Councilmember Musgrove is the current Chair of the WMO Board. City Engineer Westby confirmed that the WMO Board has representatives from Anoka, Ramsey, and Andover. Jeff Lubarski, 7826 161' Avenue, reference the comments that a Variolite access would be unsafe. He noted that 161st is on top of the hill and therefore a vehicle moving up the hill could not see a bus taking a righthand turn. Mr. Patrow commented that he is aware of the LRRWMO meeting dates and has submitted comments to that organization as well. He stated that the water issues were discussed in detail at the meeting with PACT and the neighborhood. He noted that some potential solutions were discussed and stated that perhaps the City could provide input on whether those options would be feasible, such as connecting to the storm drain that could service the church and PACT. He noted that another suggestion was to use permeable asphalt and concrete. Mr. Fincher replied that permeable asphalt is incredibly more expensive than traditional asphalt which is why it is not commonly used as it is cost prohibitive. He stated that the funding model for a public charter school is very different than a traditional school and therefore it would be challenging to add that cost. He stated that he has also heard about the incredible amount of maintenance that would be required to ensure the asphalt remains permeable. He referenced the mentioned storm drain connection and in order to do that they would still need to treat the water before tying into the connection. He stated that in order to treat the water and make the connection, that would need to occur on the south portion of the site where a lot of the mature trees are located. He was unsure of the cost that would be required to make that connection as well and recognized the desire to preserve trees in that area. Mr. Meyer commented that they did reach out to the City for as-builts of utilities at Variolite and 161' as they will connect to sewer and water in those locations. He stated that their stormwater would still need to be treated through a pond. He stated that once they receive the as -built information from the City they could investigate whether that would be a feasible connection. He Planning Commission/ June 23, 2022 Page 14 of 19
