ROAD AND BRIDGE COMMITTEE CITY OF RAMSEY ANOKA COUNTY STATE OF MINNESOTA The Ramsey Road and Bridge Committee conducted a regular meeting on Tuesday, April 11, 1995, at the Ramsey Municipal Center, 15153 Nowthen Boulevard N.W., Ramsey, Minnesota. Members Present: Councilmember Carolyn Beahen Councilmember Gerald Zimmerman Also Present: City Administrator Ryan Schroeder City Engineer Steve Jankowski CALL TO ORDER Councilmember Zimmerman called the regular meeting of the Road and Bridge Committee to order at 5:34 p.m. CITIZEN INPUT None COMMITTEE BUSINESS Case #1: Update on 153/155 Avenue N.W. City Engineer Jankowski reminded the Committee that back in June 1994, the City received a preliminary engineering report on the alignment for 153/155 Avenue between Variolite Street and Armstrong Boulevard. The consultants, RLK Associates, indicated that this alignment could be constructed with only the installation of a retaining wall to prevent encroachment of the roadway into the wetland. Subsequent to an actual wetland delineation, which resulted in the wetland being approximately 25 feet further inland than had been anticipated, the alignment could not be constructed without impacting the wetland. At that time, the Road and Bridge Committee were made aware that alternatives would be discussed with the County and State in an attempt to attain an alignment that would meet the transportation needs without impacting the wetland. Two basic options were derived. The first option most closely conforms to the original alignment. It consists of the double S type curves that would convey the traffic from 155th and Variolite directly to a cross intersection at 153rd and Armstrong. In order to retain this alignment without encroaching on the wetland, a reduction was made in the design speed of the approach curve closest to Armstrong Boulevard from 35 miles per hour down to 30 miles per hour. In addition, the cross-section of this roadway was reduced from 40 feet, in the original design, to a range of between 32 and 38 feet, with parking being restricted along the entire north side of the roadway and along the curves on the south side of the roadway. This alignment also reduces the available property remaining for development between 153/155 and Armstrong Boulevard to between 150 and 200 feet. This represents a reduction of approximately 50 feet in depth from the original preliminary engineering design. A second option for avoiding impact to the wetland consists of extending 155th due west along the section line until intersecting with Armstrong Boulevard. This alignment would require the use of Armstrong Boulevard between 153rd Lane and 153rd Avenue to carry east/west traffic wishing to travel on 153/155. A major disadvantage of this option is that it creates conflicts with accelerating and decelerating 153/155 traffic, with faster moving traffic on Armstrong Road and Bridge Committee/April 11, 1995 Page I of 4
