e "'\ I: ~~' e INGERSON PROJECT REVIEW GROUP RECOMMENDATIONS determine if they are or are not in favor of the closure. If Hamline Ave. north of Ingerson Road is closed, the Review Group recommends that not only the design/landscaping be appropriate for the area but also that considerable safety design consideration be given (e.g. installation of stop sign on Hamline Ave. at the Ingerson Road intersection). STREET STRUCTURE Review GrouD Recommendations: The original BRW feasibility report suggested that all roadways within the Ingerson Project be reconstructed down to the subbase. The Review Group members recognize and acknowledge that the City must maintain the life of a roadway. The majority of Review Group members recommend that the current subbase structure of each roadway be reviewed individuallv, taking into account the roadway usage, to determine if it is necessary to reconstruct the subbase for that particular road. If a subbase does not need to be reconstructed, the road should merely undergo a 2"- 6" cold recycle overlay, provided that the end product is a road with a consistent life expectancy throughout, which is commensurate with reconstrncted roads of the same type. There was considerable debate during the Review Group meetings over the existing street subbase. Greg Brown contends that the roads in questions should be dug up approximately 2- 2.5'and that the subbase should be replaced. This is obviously a costly endeavor to both the City and the residents. Some Review Group members believe that, based upon the appearance of the roads in the area, a complete reconstruction of all roads in the neighborhood is not warranted. The roads in the Ingerson Project area were constructed in the 1950s. Some or all of the subject roads have undergone 1-2 pavement overlays. The majority of roads within the project do not show any evidence of deterioration such as cracking, crumbling, etc., which would be signs of a poor subbase.64 Femwood Ct. was constructed in 1961, was overlaid in 1989 and was sea1coated in 1996. If the roadways are not deteriorating, it would seem reasonable to assume that the current subbase is adequate and sufficient for the neighborhood needs. According to Greg Brown, an overlay would not "seal"/correct any underlying roadway cracks. However, both Dwayne Stafford and Greg Brown acknowledge that even a newly installed road will eventually show cracks and deterioration. Some Review Group members believe that the cost ofreconstruction is exorbitant to both the residents and the City. Greg Brown advised that the cost of a full reconstruction of the roadway would cost approximately $ I 80-$200 per foot vs. $65-$85 per foot for the cost of a 4" cold 64 There are areas on the roadway that do appear to have "sunk" or cracked. However, these areas were dug up by the City and/or utility workers for repair of utilities. Poor repavement/patching is the cause of any deterioration in these areas. 27 August 17, 2000
