Public Works Supm~/isor Riemer stated the City of P,.amsey has listed in the current CEP a salt storage buikliz~g, Project #04-BLDG-005 with a bridget of $150,000.00. The building would consist of a fabric cover stretched over a steel super structure and would be placed on an asphalt pad. The pad would be constructed with in house labor. The pad is needed to keep the salt from leaching into the soil. One advantage of this type of building is that it can be disassembled in the furore and moved to a dlff~',rent site as needed. Additional sections can also be added to increase capacity if the need arises iu the future The size that staffis recommending is 70'x 100' and is capable of storing approximately 3,300 tons of material. It would allow for inside loading and unloading of material, plus the ability to store different types of de-icing material, including a salt brine tm~k for future pre-wetting systems. The current salt storage build/n§ holds approximately 200 tons. Public Works Supe~wisor Riemer explained the City's main de-icing material at this t/me is crushed rock salt, which is e['fective when pavement temperatures are at 20 degrees and rising. With tire new building they wmdd be able to keep a supply of treated salt for times when pavement drops below 20 degrees. The advantages of treated salt and pre-wetting are their ab{lily to work in much colder temperatures and the need for less material to do the same job. Some estimates arc as much as 20-30% less. Pre4vettiug works on tire principal that salt needs moisture to work; by adding moisture on the truck they can get the salt into the solution much faster, so it can start melting snow khster. It also sticks to the road better and less salt is lost to "bounce and scatter." Mr. Riemer stated everyone is trying to lower environmental impacts due to the use of chlorides. The City already incorporates much of the new technology such as ground speed controlled spinners and truck mounted pavement temperature sensors. Proper storage is an important step in the overall equation as it would offer additional space to store the new de-icing chemicals, plus offer covered loading and unloading and the ability to order ail of the salt at the beginning of the season. Mr. R3cmer advised staff estimates the cost of tl~e storage building, plus bituminrms pad would be approximately $160,000.00. Staff recommends Cmmnittee approval to move fop, yard with C1P project 04-BLDG-005 and to work with the Finance Department to secure necessary funding sources. Councilmember Olson inquired about the longevity of the structure. Public Works Supexwisor Riemer replied the structure is guaranteed for ten years. Chai~l>erson Elvig inquired about the funding source. Public Works Director OIson replied the funding would likely be from ~he Equipment Revolving Loan Fund; this will bc deternfined prior to ratification at City Council. Chairperson Elvig inquired if there are similar expenditures coming up in the CI'P. Public Works Supervisor Riemer replied there will be an expenditure coming up for fencing. Fire Chief Kapler indicated there is the feasibility ora fueling station for the Police and Fire 13cpartments. Public Works Committee / Aprfl 18, 2006 -'274- Page 2 of 10
