At its July 5, 2011 meeting, the Ann Arbor city council approved several water-related items.

The council approved a permeable surface alley project in the Burns Park Neighborhood – the alley connects Wells Street and Scott Court, running parallel to and between Lincoln Avenue and Martin Place. The porous pavement will allow rainwater to soak through the surface, reducing runoff. Money for the $121,139 contract with Audia Concrete Construction Inc. on the $200,000 project will come from the city’s stormwater capital budget. But that will be repaid as a loan from the State Revolving Fund (SRF) and will include 50% loan forgiveness. The use of stormwater funds on road construction was a practice that was criticized during the public hearing held at the council’s June 20, 2011 meeting, on the increase in stormwater rates.

The council also approved a $25,440 contract with Conservation Design Forum to design and construct a rain garden on the property at 215-219 W. Kingsley Street. The rain garden is meant to alleviate some of the flooding that occurs there during heavy rains. The parcel has drawn the curiosity of Chronicle readers due to its boarded-up house and the prodigious amounts of water that accumulate there during heavy rains. At its Nov. 15, 2010 meeting, the council accepted a FEMA grant that will help pay for the demolition of the structure to aid stormwater remediation efforts.

The council also approved a level-of-service study for its drinking water distribution system with AECOM. The outcome of the study will be a recommendation for a sustainable level of service for the city’s water distribution system, and determination of how much investment it would take to achieve that level. The study would also help the city decide, for example, which water mains should be replaced first. The council had tabled the resolution at its May 16, 2011 meeting after amending out a $10,550 contingency in the $208,984 contract. Later in that same meeting, at a session reconvened on May 31, the council took the item up off the table and postponed it until July 5.

In support of the study, city staff prepared additional documentation for the July 5 vote.

At its Feb. 7, 2011 meeting, the Ann Arbor city council authorized a $460,139 contract with DLZ Michigan Inc. to review previous studies of the Fuller Road/Maiden Lane/East Medical Center Drive intersection and propose a design for a reconfiguration of the intersection. Previous studies point to a roundabout as a good solution to the traffic congestion at the intersection. The poor level of service (LOS) in that area has prompted the city to propose various solutions to the intersection redesign, dating back at least to 2005. Depending on the time of day, the intersection currently rates D and E on the letter-grade scale used to evaluate traffic flow.

In the city’s capital improvements plan (CIP), the intersection improvement is categorized with bridge projects – it’s immediately adjacent to the Maiden Lane bridge over the Huron River.

In 2009, the city studied the intersection in the context of increased traffic load due to possible construction of the Fuller Road Station – an intermodal transit center and parking deck proposed for the area between Fuller Road and East Medical Center Drive. The city’s online meeting packet includes drawings of the current configuration of the intersection as well as the possible roundabout configuration.

The engineering and design of the roundabout project will be funded out of the FY 2011 capital budget for the city’s street reconstruction millage. Construction is expected to be funded out of a combination of: (1) millage revenues in future years; (2) possible funds from a federal Congestion Mitigation Air Quality (CMAQ) grant; and (3) a contribution from the University of Michigan.

In a telephone interview Monday morning before the evening council meeting, Homayoon Pirooz, in the city’s project management unit, told The Chronicle that construction on any project would not begin before the summer of 2012, with 2013 a more likely timeframe. Pirooz ballparked the construction cost of a project like this – once all the traffic lanes leading to the intersection are modified, and the pedestrian amenities are installed – as possibly more than $2.5 million.
