2008 Comprehensive Plan The level of service (LOS) provided by TH 10/169, TH 47 and all County Roads can be characterized using a letter grade system. A LOS letter grade can be assigned to a facility based upon the ratio of traffic volume to traffic capacity. LOS A represents low congestion and LOS F represents conditions where traffic demand exceeds traffic capacity. The existing LOS grades for these two roadways were determined based on the 2007 Mn/DOT recorded traffic volumes and the roadway capacity calculations for LOS D conditions for volume capacity thresholds generally accepted by Anoka County for various roadway types. TH 10/169 performs at LOS F along its entire length through Ramsey. TH 47 performs at LOS D between the northerly city limits and Alpine Drive. Between Alpine Drive and Nowthen Boulevard performs at LOS A and between Nowthen Boulevard and Bunker Lake Boulevat WIS C. These level of service ratings indicate that TH 10 and TH 47 preseare o near or at their capacity limits within the City of Ramsey. This condit r incipally is due to trips generated from outside the City limits and, f r h_ ore, ; utside the current seven county Metropolitan Area. f _ C. Analysis of Roadway System Needs 1. Planned Changes to Roadway System Ramsey is a rapidly developing community. Ne — tions to the public street system are expected, primarily in the fof local and_ollector streets (see Figure VI -2). The only new arterial expected to b.structed is the extension of CR 116 westward from its present terminus at Armstlong lvard. An addition to the roadwafem udes the extension of 167 Avenue between Variolite Street and Nowlien Mid. This addition to the system is important to provide an effective e - ve people through the community in an east -west direction. = = = There are two'ptiaoadway extensions into neighboring communities, which would require the 1 tial consent of Ramsey and the affected communities. These includee v,stwaid extension of 173 Avenue into Elk River and the eastward extex�on Kinley Street into Anoka. The likelihood of either extension is low, pearly for the McKinley Street extension, which is opposed by the City of Alta. the 173r Avenue extension would primarily duplicate the current function of 1 Snue. If Elk River constructs the north -south arterial link in its Fillnmore Strut and Jarvis Street corridor as shown in Elk River's comprehensive. transportation --Mini of November 1995, the 173r Avenue extension would offer Ramsey residents a connection to this corridor for use as an alternative to CSAH 83. Extending McKinley Street into Anoka would limit the amount of truck traffic that would have to travel on ` Highway 10 for a short distance. A corridor study prepared in 1988 for TH 10/169 recommended that a frontage road system be established along both sides of TH 10/169. Ramsey has constructed a frontage road along the south side. The corridor study also recommended the closure of median breaks and driveway access points along TH 10/169. The Anoka County Highway department favors upgrading TH 10/169 to freeway standards with limited access and grade separated interchanges. This has not been identified in the Mn/DOT Transportation Improvement Program through 2010. Upgrading would improve capacity and safety. An updated TH 10 /169 - corridor study is suggested to determine 2008 Ramsey Comprehensive Plan Page VI -7 -291-
