the pump. Utility Supervisor Nelson stated a variable frequency drive was added to control the flow to 850 gallons/minute without closing a valve. Variable frequency drives also creates a soft start and shut down function and reduces electricity use. Chairperson Riley asked if there are well pumps that can be increased to produce more water. Utility Supervisor Nelson stated that could be done but then staff would have to do some sampling to assure sand is not also being pumped. He invited the Committee to stop by to tour the water towers. City Engineer Westby stated it was mentioned that only one well has a fixed generator and asked how many mobile generators the City has. Utility Supervisor Nelson stated the City has one portable generator that is used for lift stations only as it cannot power a well. The CIP includes an additional generator for Well #2 (estimated cost of $150,000) and it could also run Well #3. He stated normal demand could be met with two generators. Utility Supervisor Nelson reviewed the opportunity for mutual aid support with the City of Anoka. The Committee thanked Utility Supervisor Nelson for the informative update. Informational; no action required. 5.02: Staff Updates on Improvement Projects / Items of Interest City Engineer Westby stated at the last meeting staff was asked to provide more regular updates. He referenced the staff report that listed the most high profile City projects and provided updates on the Highway 10/County Road 83/Armstrong Boulevard interchange with project completion expected in late May; preparation of the Business Park 95 Regional Stormwater Pond Improvements plans with construction expected this summer/fall; progress made with the Andrie Street and 164th Lane reconstruction plans with construction expected to begin early June and completion in October; and the 2016 Mill and Overlay Project, which was scaled back in consideration of Anoka County's pavement maintenance project on Bunker Lake Boulevard between Ramsey Boulevard and Basalt Street, with construction to begin early August and completion mid -September. With the overlay project, he explained that the Council will need to consider whether to assess only a few of the properties on Sunwood Drive. Chairperson Riley noted that last year, the City assessed some properties for an overlay project and asked if those assessment amounts would be a reasonable target amount for the 2016 overlay proj ect. City Engineer Westby stated that can be used as a target but staff will have to consider average driveway spacing and future overlay projects to assure consistency. He continued presenting the staff report noting the 2016 Sealcoat Project will start construction early July and completion in August. Public Works Committee / March 15, 2016 Page 4 of 8
