City Council Regular Meeting Minutes April 11, 2006 Page 2 1 project is needed based on the increase in sanitary sewer flow because of the Silver Lake village 2 development. He presented several options and recommended utilizing pipe bursting for the 3 Arunk sanitary sewer from Silver Lake Road to the Foss Road lift station, and a directional bore 4 forcemain from Foss Road to the Roseville system. It is also recommended to construct a lift 5 station. Mr. Hubmer used a map to note the location of the Foss Road lift station, which will be 6 a small sized building to house the generator, pumps, submerged wells 33 feet below ground, and 7 a hoist that can be used to lift out the pumps, if needed. 8 9 Mr. Hubmer also noted the location of a property owner to the east and advised that staff will 10 meet with them when the well house is being built to assure minimizing impact to the adjacent 11 landowner. 12 13 Mayor Faust asked about constructing the lift station so it appears to be a house. Mr. Hubmer 14 explained this is an industrial area with a framing shop to the back so he would recommend an 15 industrial themed lift: station. 16 17 Mr. Hubmer presented the project costs and proposed financing, noting the total project cost is 18 $1,864,400. Proposed funding includes the Sewer and Water Utility Fund, Public Improvement 19 Bonds, and developer SAC and WAC fees. Mr. Hubmer then presented the project schedule. 20 21 Councilmember Stifle requested the definition of the different types of boring. Mr. Hubmer 22 described pipe bursting and directional boring tunneling technologies. Councilmember Stille 23 asked what is the advantage of either technology. Mr. Hubmer recommended pipe bursting in 24 39th Avenue because there is an existing pipe. On the force main there is no existingpipe so pp 25 directional boring is recommended. The advantage of both is that the streets do not have to be 26 torn up and restored. 27 28 Councilmember Stille stated that 39th and Chandler Streets could be redone now and asked if it is 29 a mistake to not do the whole project. He also asked how much life is left in those streets. Mr. 30 Hubmer stated 39th Street may be at the end of its life but if the land uses or development 31 changes, then there would have to be a change in the utilities. 32 33 Mayor Faust asked about the level of disruption this time versus waiting to do the entire street. 34 He noted residents cannot stand it when a street is dug up and then three to five years later it is 35 dug up again. Mr. Hubmer explained that with pipe bursting they will dig up where the services 36 are and it only involves about a week of work. 37 38 Councilmember Thuesen asked if this will provide capacity for what is needed today plus the 39 future. Mr. Hubmer stated they did add projections for future growth. He noted the City now 40 has to size the system to accommodate the I/I flows but once those flows are removed, it frees 41 capacity to handle future development. 42 43 Mayor Faust asked if the project takes into consideration the buildout of the yet to be built 44 homes, businesses, and teardown. Mr. Hubmer answered in the affirmative. 45 3
