Infrastructure Items Get Council OK

Several infrastructure items received approval at the Ann Arbor city council’s July 7, 2014 meeting – related to sidewalk special assessment rolls, pool liners, and street repair.

Receiving final approval were special assessments of property owners to help pay for construction of three different sidewalks – on Stone School Road, Barton Drive and Scio Church Road.

The new sidewalk on Stone School Road will be on the west side of the road. This work will be done in conjunction with the Stone School Road reconstruction project from I-94 to Ellsworth Road. The total sidewalk project cost is roughly $128,500, of which about $55,000 will be special assessed. A public hearing on the special assessment took place at the council’s July 7 meeting. Three representatives of the Jehovah’s Witnesses, which owns property on Stone School Road, addressed the council about the amount of the special assessment they’ve been assigned. They asked for some kind of waiver, given the nonprofit status of their organization. Mayor John Hieftje indicated that city staff would provide them with options.

The Barton Drive sidewalk project will extend eastward from Bandemer Park at Longshore Drive. The cost of the Barton Drive sidewalk has been calculated to be $80,606. Of that, about $36,000 will be paid from federal surface transportation funds. Of the remaining $44,606, the city’s general fund would pay $42,626, leaving just $1,980 to be paid through the special assessment.

For the Scio Church sidewalk project, the total cost is expected to be $365,100. Of that, about $164,000 will be paid from a federal surface transportation grant. The remaining $201,100 will be paid out of the city’s general fund and by the special assessment of just $1,626.

Several other contracts appeared on the council’s July 7 agenda that were related to infrastructure maintenance and repair. The council approved a $344,600 contract with Cadillac Asphalt LLC for repair of streets after water mains, storm and sanitary sewers are repaired. The city’s public services area does not have the equipment or the staff to perform these types of street repairs, which often involve the replacement of the concrete base or the concrete street surface, according to the staff memo accompanying the resolution.

The city council also awarded a $175,000 contract to replace a clarifier drive in the drinking water treatment plant – to Titus Welding Company. According to a staff memo, the drive to be replaced is original to the plant and was installed in 1965. It had an expected life of 30 years. It has begun to show signs of failure, included seizing, high vibration, and bearing failure. The drive has been assessed by the manufacturer and it has been determined that it is not cost-effective to repair, according to the memo.

Also approved by the council was a $205,055 contract with Renosys Corp. to install PVC pool liners at Buhr and Fuller pools. The city is switching to PVC from Marcite, which is, according to a staff memo, a “cementitous product that covers the pool shell creating a smooth and waterproof surface.” The new product has a smoother surface, and won’t require the yearly patching required due to harsh winters and wear and tear on the pool, according to the staff memo.

Also approved at the July 7 meeting was a $80,836 contract amendment with Tetra Tech Inc. for environmental consulting services at the now-closed Ann Arbor landfill. That brings the total amount on the contract to $624,221. According to a staff memo, for several years the landfill has had a plume of 1-4 dioxane and vinyl chloride contamination offsite primarily in Southeast Area Park, northeast of the landfill. A slurry wall was constructed along most of the boundary of the landfill to eliminate groundwater passing through the landfill, and three purge wells were used to attempt to capture the offsite contamination.

And finally, the council passed a resolution approving $125,000 contracts with Stantec Consulting Michigan Inc. and Fishbeck, Thompson, Carr & Huber Inc. for general civil engineering and surveying services. Those services include a range of activities, according to the staff memo accompanying the resolution: design and management of capital improvement projects; private development construction plan review; private development utility and road construction inspection; traffic engineering; civil engineering design; construction inspection; drafting; and surveying.

This brief was filed from the city council’s chambers on the second floor of city hall, located at 301 E. Huron.
