Minutes of Council Workshop Meeting Village of Arden Hills Wednesday, June 20, 1984 - 7:00 p.m. Village Hall Call to Order Pursuant to due call and notice thereof, Mayor Woodburn called the meeting to order at 7:08 p.m. Roll Call Present - Mayor Robert Woodburn, Councilmembers Dale Hicks, Michael Christiansen, Kathleen Rauenhorst, Thomas Mulcahy - None - Engineers Norm Hendrickson, Donald Christoffersen, Treasurer Donald Lamb, Public Works Supervisor Bud Johansen, Public Works Committee members, Clerk Administrator Charlotte McNiesh, Deputy Clerk Dorothy Zehm . Absent Also Present Water Tower Needs Assessment - Engineer Norm Hendrickson Council was referred to a data package, copies of which were distributed to Council. Hendrickson explained that the population figures used were based on the Comprehensive Plan population study made by the City Planner; based on this study, the 1983 estimated population connected to the Arden Hills water system is 6,350; noted that the estimated population connected in 1994 is projected at. 10,200 after deducting population of direct connections to Roseville (295) and the mobile home park (873). Hendrickson referred Council to actual Arden Hills water pressure chart indicating water levels and water consumption at Arden Hills' tower on August 6, 1983. Hendrickson noted that between 6:30 a.m. and 11:00 p,m., when pumps are pumping, pressure drops to 40 psi (considered a low pressure for industrial areas). Hendrickson explained that he chose August 6th because it is a Saturday, when there is not much industrial use, but a good water use day. Hendrickson reported that the Roseville booster station (Arden Hills' water source) is capable of pumping in excess of the Roseville/Arden Hills fire demands as recommended by Insurance Services, which are: - 4000 gpm for 5000 gpm for 3000 gpm for 4 hours to 5 hours 3 hours Industrial is considered a reasonable fire demand for a city of the nature of Arden Hills, according to Hendrickson. Hendrickson noted that insurance rates are based on the City's rating class. Arden Hills currently is class 6. It was noted that the lower the class the lower the rate; probably a class 6 because of volunteer fire department status. Hendrickson noted that cities are not required to provide for fire demands; noted these are the figures recommended by fire underwriters. . Hendrickson noted that consumption by Arden Hills & Roseville combined was 11,066,652 gallons, on 8/6/83; 15.2% of this consumption is the estimated consumption of Arden Hills based on the 6350 population figure (1,682, M gallons); noted that it is common practice to store an average day's water usage. Peak hour, maximum day and average day Arden Hills water consumption were noted by Hendrickson as well as the estimated consumption anticipated for a maximum day plus fire demand, and for a maximum day plus fire demand with arsenal connection. Hendrickson referred Council to chart showing peak hour daily consumption compared with peak hour consumption with arsenal connection.
