. . . Arden Hills Council 6 April 12, 1993 '\Ij,l1QE'l!,-t"AJ:lc:l"xson_~325 Karth Lake Circle - I am uncomfortable with Graham's response to Ralph Larson's comments, wherein he said it may be necessary to "try to mill" portions of existing streets, I get the impression that there is no plan as to how to address problems, but rather the engineer will simply "try" certain measures. The information sent to me by mail was vague and unclear, In the future, the City should send out more specifics. Graham stated that the "milling" process is relatively a new process, but that it has been done by engineers and contractors with success and is considered a suitable process to be used as needed, He added, however, that it is more expensive to "mill" a street section, so it will be done only when a determination has been made that it is necessary. Arlene Mitchell, 1283 Wynridqe ~rive - To what extent does overlaying a street extend its life expectancy? There is little traffic and no potholes yet on my street; its rating is not bad compared to others in the neighborhood. I appreciate preventive measures, but question whether overlaying my street at this time is premature. Graham responded by saying that there are many points to consider when determining when to overlay a street, such as distressed pavement, cracking, maintenance records, age, etc. He added that another consideration is that typically there can be much better bids by "clustering" a number of streets in a neighborhood and overlaying all of them as a complete package. He added that he feels Wynridge Drive is due for overlayment now before there is worse deterioration of the street. He offered to discuss his analysis with Ms, Mitchell after the public hearing if she desired. Q~ott ~Qlso~ 1321 Wyncrest Court - How often does the City perform inventory/analysis of streets? I question whether overlayment of Wyncrest Court is warranted at this time because there are no potholes; perhaps it should be postponed for a few years, Graham explained that about every three years a City-wide street inventory/analysis is conducted, and City crews rev~ew streets even more regularly. He reiterated that it is cost effective to overlay a street to extend its life before it is in a very deteriorated state. Mayor Sather asked if anyone else wished to speak; there was no response. The public hearing was closed at 8:27 p.m.
