Motion carried. Voting Yes: Chairperson McGlone and Councilmembers Elvig and Backous. Voting No: None. Case #3: Consider Policy on Turf Establishment Related to City Improvement Projects City Engineer Himmer reviewed the staff report. Chairperson McGlone stated his support to require sod since it has roots to quickly establish turf and address erosion. He felt requiring sod would result in fewer headaches in the long run and the City can assure the contractor is meeting specifications. Councilmember Backous stated he was thrilled with this proposal, which will be more costly up front but save staff time and residents will be happy with it. City Engineer Himmer explained that ditches are to promote infiltration so staff suggests not using costly soil. Councilmember Elvig asked whether the requirement of 4 inches of topsoil is overkill. He stated in his yard he put down one -half inch of topsoil and his yard is now more green than others in the neighborhood. Councilmember Elvig suggested talking with contractors about salvage dirt and the need to pick out rocks. He stated he understands the need to address erosion but was concerned that property owners would not take care of sod. To keep it affordable, he suggested the seed be sown; not broadcast, and watered every 2 -3 days to assure it will grow. City Engineer Himmer stated sod is a good means of erosion control and this specification, whether seed or sod, requires the contractor to water it for 30 days. In 30 days, sod will be established but it takes longer for seed to be established. City Engineer Himmer stated staff talked about the impact of salt and sand during the winter months and whether it was the contractor's or homeowner's responsibility to cut out and replace that sod. He noted that sod gets rid of the concern with rocks. Councilmember Elvig asked what is the cost between sod and seed. Public Works Director Olson estimated the cost on Ute Street was $300 -$500 per address. He noted the specifications for that project tried to make it as affordable as possible to get the project done. Residents were offered $200 to salvage top soil. The area was seeded and steeper areas were hydro seeded. Public Works Director Olson noted a picture can be taken at the end of the project to show turf has been established. With regard to sod damaged by road salt, he asked why the contractor should not be required to replace it since a 12 -month warranty is required. City Engineer Himmer reviewed the cost of sod and seed, noting both require topsoil. Councilmember Elvig asked whether 4 inches of top soil would be required for sod.
