th 5.03: Review Overlay Project 11-05 (157 Lane East of Ramsey Boulevard) Public Works Superintendent Riemer reviewed the staff report. He agreed the center line is not the best but any repair options will create a project that does not look as well. He advised that the core samples taken are all within specifications and he thinks the road is structurally sound, noting it shows no signs of stress after being driven on for one year. He recommended leaving the road as is and monitoring it to see if anything happens. th Dale McKusick, 6801 157 Lane NW, stated his concern that the asphalt is inconsistent in depth, especially as it approaches the curb, an area that carries water drainage and traffic from plows and garbage trucks. He stated he put in a new driveway for his neighbor and found there was only one-half inch of asphalt at that driveway. He agreed with Public Works Superintendent Riemer that grinding down the center would not be an acceptable repair. Mr. McKusick stated the asphalt mat should be a consistent 1.5 to 2 inches thick from edge of curb to edge of curb, but it is not and he thinks the road edges will come apart within several years. He noted the original road was surfaced only once in 30 years, held up well, and is providing a great base for the sealcoat project. However, as it deteriorates, there will be no recourse against the contractor and everyone will be mad at the City. Mr. McKusick stated there has to be someone accountable and if he is paying taxes, he wants it done right. Chairperson Backous stated he agrees enforces its building codes with strict inspections but he does not know about the inspection process for this project. Councilmember McGlone noted at the time of this project, the City had two engineers and used the same engineering inspection team so there was not an issue with manpower to inspect the project. th Barb McKusick, 6801 157 Lane NW, stated they were told it would be 1.5 to 2 inches thick from curb to curb and that part of the existing bituminous curb would go away. However, along most of the street the bituminous curb remained so people are asking how thin the asphalt is if the curb is still showing. Councilmember Elvig asked what is the depth of the asphalt. Public Works Superintendent Riemer stated he can take additional core samples of the edges and may find some at one inch and others at two inches. Ms. McKusick stated the issue is that the asphalt mat is not consistent. Mr. McKusick agreed that most of the bituminous curb remains after the project so it means the matting is not consistent. Councilmember Elvig stated the struggle is that a concrete curb it is definite but with bituminous curbs, the spreader floats so the mat undulates. He asked Mr. McKusick if he thinks an entire area is substandard. Public Works Committee / July 17, 2012 Page 2 of 9
