Honorable Mayor and City Council March 7, 2002 Page 2 users come on line in the beginning. When the volume of water being used is Iow and the line is a dead-end with little or no circulation, the Water Utility tends to get water quality complaints. These can be remedied if they occur by simply flushing the watermain through one of the hydrants in the development. The final concern would be fire-fighting capabilities should a watermain break occur or on the extreme dead-end portion of the watermain system. This should pose a relatively small problem since the fire department can easily fight a residential fire in an area that has no water service. Staff's conclusion in our discussion relative to the Developer's desire not to fund any water improvements on 175th Avenue is that there are three options. They are as follows: Proceed with the water improvements under 175th Avenue from Tyler to Park Pointe Addition, requiring the Developer to pay for these improvements. The Developer would pay for the lateral equivalent with trunk oversizing funded by the City. Eliminate the detached trail on the north side of the 175th Avenue improvement, not install the watermain at this time, and wait until there is demand for water service from the properties abutting 175th Avenue on either the north or the south. The watermain could be easily installed in the future in the corridor left vacant by the elimination of the detached trail without damaging the newly constructed road surface. The difficulty would be in extending water services under 175th Avenue to service the south side of the road. These would have to be directionally bored under the road at a slightly higher cost than if they were constructed with the road project. The watermain could be installed as discussed with the road improvement, but not have the Developer of Park Pointe Addition pay for the improvements. We would recommend that if this option is chosen, the Elk River Municipal Utilities be asked to fund the improvement until such time as the abutting properties can be assessed for water service, and they would be reimbursed for their expenditure. This is similar to the trunk watermain construction planned in 2002 from Kliever Lake Fields to the new water tower site in Eagles Marsh. In discussing the need for the water line under 175th Avenue with Bryan Adams, relative to the benefit of the overall water system, he indicated that he is concerned about future developments such as Elk River Station and the ability to provide large quantities of water for peak domestic demand and fire fighting needs. Without the loop from Park Pointe to Tyler Street, essentially large quantities of water contained in the new water tower will have to flow northerly to CSAH 12, then along through Trott Brook Farms to Tyler Street and south along Tyler Street to the area of Elk River Crossing, rather than coming out of the water tower to Park Pointe down 175th Avenue, which is a much shorter route to the area of the Elk River Station development. If the City Council chooses option "b" described above, then the watermain becomes an Elk River Municipal Utilities issue if they desire it to be included in the 175th Avenue improvements.
