MINUTES OF THE ORONO CITY COUNCIL MEETING Monday, October 25, 2010 7:00 o'clock p.m. (9. LONG LAKE - ORONO WATER SYSTEM, Contii:ued) of the well was 800 gpm. 'Currently the capacity has fallen to 500 gpm due to infiltration of sand when pumped at higher capacities. The improvements identified for 2016 and shown as North Well Pump Maintenance would redevelop the well and hopefully restore some of the lost capaeity. Kellogg stated the water tower was built in 1995 and the painting of the tower is a routine maintenance item in order to protect the City's investment. They will need to determine the extent of the necessary repairs. In order to plan for the future ultimate service area, they will also need to determine where the water is going. The required storage for fire is added to the storage needed for maximum day demand. In addition, the fire storage is based on 3,500 gpm for three hours. This number is chosen because it is the number that the ISO gives the maximum allowable points for the distribution system portion of the overall fire rating. For small communities in Minnesota, this results in an often unrealistic volume of storage. In this situation, the resultant volume of 630,000 gallons will often cause winter freezing problems. Many smaller communities choose a lesser fire flow in an attempt to serve the customer base and at the same time prevent winter freezing. This lesser number usually falls between 1,500 gpm for two hours to 2,500 gpm for three hours. This would result in required storage volumes of 180,000 to 450,000 gallons. 0 In 2009, the Orono Public Works Department went through an exercise to develop a 7 -year CIP. The CIP included identifying the water distribution improvements necessary for the north water distribution system. Based on that study, there is a potential significant cost in the next seven years to complete the • recommended CIP work. Some of the work is higher in priority than other work. The water tower inspection work is to identify the timing of the repainting and rehabilitation of the north water tower. This work should be done soon so that the water tower work necessary and associated costs can be further refined. Water tower rehabilitation and repainting is generally planned for on a 15 to 20 year cycle. The north water tower was constructed in 1995. Doing the inspection work now will not only help refine the estimated improvement costs but will help identify the timing of the project. Kellogg noted attached to the report is a graphic of the existing water system. White stated over the years more information has been gathered on the city's overall infrastructure, which has been a major improvement and assists in determining what projects should be undertaken. The City Council took no formal action on this item. 10. OLD CRYSTAL BAY ROAD RECONSTRUCTION FEASIBILITY STUDY — RESOLUTION NO. 5981 i White noted the preferred option by the members in attendance at the road meeting was Option 2. Franchot commented that what is done in that area will be what will be there for a number of years and that he is disappointed the school system does not have more ability to partner with the City but that he understand their constraints. Franchot indicated he would prefer Option 2 with three roundabouts and a wider median. An objective • could be set to make the median a reasonable barrier without spending a considerable amount of money on it. Franchot stated in his view Option 2 will best meet the needs of the community and offers the Page 12 of 17
