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