P13 CITY COUNCIL WORK SESSION June 4, 2012 DRAFT 45 The council discussed street access and emergency vehicle access; it may make more 46 sense to consider a through street rather than a cul -de -sac. 47 48 When Council Member O'Donnell asked about next steps, Mr. Grochala noted that the 49 staff report explains the city process. The developer would normally engage an engineer 50 for formal planning. If a development team were put together, he would suggest they 51 meet with city staff. Mr. DeHaven expressed concern about the escrow system and city 52 charges that are incurred through that process. 53 54 When Council Member Roeser asked if there may be some funding available on a 55 regional level for a development like this, Mr. Grochala explained that he wouldn't see 56 anything available for something on this scale. 57 58 Not relative to the housing development discussion, Public Services Director DeGardner 59 remarked that the garden club that includes Mrs. DeHaven has done a wonderful job with 60 the landscaping work outside of city hall. The council expressed their extreme 61 satisfaction with the result of the landscaping and noted that they will formally recognize 62 the volunteers at an upcoming council meeting. 63 64 Water System Discussion (added agenda item) — Public Services Director DeGardner 65 noted that a "Don't Drink the Water" advisory was issued for the City of Lino Lakes this 66 day and he introduced the city's Utility Supervisor Tim Hillesheim to further explain that 67 situation. 68 69 Mr. Hillesheim explained that this morning at about 3:30 or 4:00 a.m. the SCADA 70 computer system for the city's water system locked up during a routine data backup - 71 why that program locked has not yet been determined but is being studied. That means 72 that communication with the wells ceased and pressure started going down. This is 73 irrigation season so it went down pretty fast. There is a redundant dialing system that 74 then failed. He was notified by the Police Department at about 4:30 or 5:00 a.m. of the 75 pressure problem and that they were in the process of manually turning on the pumps. 76 Mr. Hillesheim arrived on the scene by 5:30 a.m. and can report that by 6:00 a.m. the 77 wells were fully pressurized. At no time did the wells run into a negative pressure 78 situation, which is what the Health Department worries about. The Health Department 79 felt that the potential did exist for that negative pressure and the result is that they issued 80 the advisory. They are testing the water in the system and he is very confident there will 81 be no problem. Additional steps that could be taken to avoid the problem in the future 82 would be to have Roseville (our IT partners) monitor our SCADA system at all hours of 83 the day (as they do for a couple of other cities), and/or to install pressure transducers as 84 another fail safe. 85 86 Council Member Roeser asked if the Health Department had known that there was never 87 a negative pressure, would they still have initiated the advisory? Mr. Hillesheim said no 88 and Mr. DeGardner added that there will be some follow up conversations with the 89 Health Department to ensure that proper protocol has been followed and to develop full 2 • • •
