CITIZEN INPUT None COMMITTEE i BUSINESS Case #1: Update on 153/155 Avenue N.W. City Engineer Jan~kowski 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 the 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 anticipa!ed, 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 th~. County and State in an attempt to attain an alignment that would meet the transportation ne4ds without impacting the wetland. Two basic options were derived. The first option mosticlosely 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 158rd and Armstrong. In order to retain this alignment without encroaching on the wetland, aireduction was made in the design speed of the approach curve closest to Armstrong Boul .o~vard 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 a~d 38 feet, with parking being restricted along the entire north side of the roadway and alo~ng the curves on the south side of the roadway This alignment also reduces the avmlable property remmmng 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 intersectin~ 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 bn 153/155. A major disadvantage of this option is that it creates conflicts with acceleratingland decelerating 153/155 traffic, with faster moving traffic on'Armstrong Road and Bridge Committee/April 11, 1995 Page 1 of 4
