ROAD & BRIDGE COMMITTEE CITY OF RAMSEY ANOKA COUNTY STATE OF MINNESOTA The RamSCy Road & Bridge Committee conducted a regular meeting on Tuesday, June 14, 1994 at the Ramsey Municipal Center, 15153 Nowthen Boulevard N.W., Ramsey, Minnesota. Members Present: Mayor James Gilbertson (arrived at 6:46 p.m.) Councilmember Gerald Zimmerman Also Present: City Administrator Ryan Schroeder City Engineer Steven Jankowski Finance Officer Jessie Hart Don Schaeffer, RLK Associates CALL TO ORDER Councilmember Zimmerman called the regular meeting of the Road & Bridge Committee to order at 5:32 p.m. CITIZEN INPUT None APPROVE AGENDA Consensus was to approve the agenda as presented. COMMITTEE BUSINESS Case #2: Receive Feasibility Report on 153rd/155th Avenue MSA Road Extension City Engineer Jankowski stated that the preliminary engineering report was prepared by RLK Associates, as was directed by City Council. The consultant detailed an alignment which was most consistent with that reflecting Staff's conceptual plan which was the basis for the Environmental Assessment Worksheet. This alignment, identified as Alternative A, intersects at the current intersection with 153rd Avenue N.W. and Armstrong Boulevard N.W. at a right angle and turns northward using a 40 mile per hour design speed curve. This alignment resulted in impacting approximately three acres of wetland. The consultant was directed to search for alternatives which would minimize the wetland impact. They devised Alternative B which reduced the wetland impact to less than 0.2 of an acre. This alternative: required skewing the angle of intersection with Armstrong Boulevard N.W. by 15° from perpendicular, reducing the curve design speeds to 35 miles per hour and building a retaining wall to avoid all but a small portion of the wetland. Mr. Jankowski stated that a slight revision of Alternative B results in the recommended alternative, Alternative C, which completely avoids any impact on the wetland. This alternative proposes moving back the beginning of the skew approach to Armstrong Boulevard N.W. to the west for a distance of approximately 200 feet. The avoidance of any impact to the wetland is an issue which is s~ongly supported by the citizens that have provided input on this project at the many meetings held regarding same. This report also addresses the citizen concerns about impacting.the drainage from this roadway onto Wetland/ti 11P which is a landlocked water body. Based upon the consultant's analysis, a 100-year event would have an impact on the Road & Bridge Committee/June 14, 1994 Page 1 of 3
