Marley, P.E., Director of Public Works Keith D.Alexander, Director of Water Management SUBJECT: Emergency Repairs Resulting from a Water Main Break North of Garfield Avenue on Woodford Street SUMMARY RECOMMENDATION: It is recommended by staff that the City Council approve the attached resolution authorizing the expenditure of$17,217.90 to Barr&Robison Sewer&Excavating, Inc. for the replacement of a sanitary sewer manhole and pipe which was damaged from a water main break on Woodford Street north of Garfield Avenue. PRIOR COUNCIL ACTION: No prior Council action has been taken on this repair work. The City Manager was made aware of, and signed, an emergency order(attached)to perform the necessary repairs under Chapter 46, Section 2 of the Decatur Municipal Code. BACKGROUND: On Monday, March 28, 2011, a 12" water main break under Woodford Street was discovered. During the investigation it was determined that water from the broken main was flowing underneath the concrete pavement across the street to a nearby brick sanitary sewer manhole. Water from the main break had been flowing for an undetermined amount of time and had created a large void under the pavement and eroded away the base and foundation of a sanitary sewer manhole. The necessary repair work was initiated on Wednesday, March 30, under the authorization of the City Manager acting in accordance with Chapter 46, Section 2 of the City Code due to the threat posed to the health, safety, and welfare of the public. The manhole was 5' in diameter and over 12' deep which is beyond the ability of City crews to repair due to the shoring and additional equipment required for an excavation of this depth. Barr&Robison Sewer and Excavating was retained to perform the necessary Page I 1
