Value Procurement Process providing the opportunity to get the best contractor for the job, not just awarding the work to the lowest bidder; and potential revisions to City Code related to permeable pavements as indicated in the case study (Attachment C) and addressing newer technologies. Discussion included how and by whom surface area/impervious surface calculations are made as part of the building permit process and determining whether or not a variance is required; variables from one community to another, and differences for lake properties from typical city-wide parcels. Chair Stenlund supported the City moving forward with any code revisions, as long as a formal, written maintenance plan was put in place to ensure the system would work for any future homeowners inheriting the driveway to keep it functional (e.g. draining) from one owner to another. Chair Stenlund expressed his interest in this particular case study to determine long-term drainage. As part of any written maintenance plan, Chair Stenlund suggested ordinance language provide for vacuuming or other methods to ensure the system continued to be permeable, and not become impermeable due to build in the cells. At the request of Member Seigler, Mr. Culver reviewed options for existing homeowners who may wish to exceed impervious surface coverage under current regulations, by applying to the City for a stormwater management permit for installation of mitigation efforts (e.g. rain barrels, rain gardens, pervious pavements) all reviewed and approved or denied on a case by case basis. Mr. Culver advised that this was not an option for new construction, as expectations are that calculations will stay under the proscribed percentage allowed versus remodeling or adding onto an existing structure where every available means was undertaken to slow the rate and quality of water. At the request of Member Cihacek, Mr. Culver clarified new construction options and residential stormwater permit processes requiring five year recertification of any device installed, with the City burdened in managing that certification process and added cost to the individual properties to go through that recertification. At the suggestion of Member Cihacek, Mr. Culver agreed that the City could always improve on their educational efforts for homeowners to be aware of and learn how to maintain their systems for successful recertification and to avoid additional costs. Chair Stenlund opined that new purchasers of those properties should also be made aware of what they're buying with those systems, as part of the due diligence involved in the purchase. At the request of Member Cihacek, Mr. Culver provided an update on the Lexington Avenue/Highway 36 bridge reconstruction project, with the Minnesota Department of Transportation (MnDOT) currently in the final design stages and planning for an informational meeting yet this fall. Mr. Culver reported that MnDOT was working Page 2 of 16
