CASE #5 ACCEPT PLANS AND SPECIFICATIONS FOR CITY PROJECT #08-27, 167TH AVENUE NW REALIGMENT, AND AUTHORIZE FOR BID By: Tim Himmer, City Engineer Background: On April 8, 2008 City Council authorized staff to prepare plans and specifications for the realignment of I 67th Avenue NW. As you may recall this realignment related to segment one only (Nowthen Boulevard to Limonite Street). During that meeting staff expressed interest in expanding the project approximately 500 feet to the west to eliminate the next set of drastic . curves along 166th Avenue NW, and including municipal utilities in the design; both of which were subsequently approved. . The original overall proposed alignment showed drastic impacts to the home located at 7131 1 66th Avenue NW, most likely amounting to a totaltaking of that property. Three alternative roadway alignments were advanced and discussed several times with the City Council, and the final decision was made on June 24, 2008 settling on the current alignment. The chosen alignment was a compromise which resulted in a 25 mile per hour design curve through the western end of the project, thereby reducing the impacts to the existing residents and wetland. The reduced design speed through this curve necessitates the need for a variance from: MnDOT, which i$ tentatively scheduled to be heard on June 11,2009: A council resolution is required. and attached to this case for consideration. Staff has received comments from all reviewing agencies, all of which are favorable for the project. Due to our design in reducing impacts to the existing wetland on 1 66th Avenue we will be able to utilize State banking credits for the minor impacts proposed. State Aid will cover 100% of the cost for the proposed storm sewer and associated ponding. The County has stated they are supportive of the project, but a right turn lane from southbound CSAH 5 must be constructed at this time. They also commented that an agreement should be put in place which states that left turn lanes will be constructed on CSAH 5 when 16ih Avenue is extended west to Variolite; a formal agreement will be forthcoming in the future. Observations: Acquisition A total of 6 parcels will be impacted by this project; 4 fee title takings for right-of-way and ponding, and 2 temporary easements for construction purposes. The total cost of these acquisitions has been negotiated to an amount of $183,800 (to be reimbursed through State Aid dollars), and construction improvements primarily related to access drives and utility stubs. It should be noted that a case will be heard at the Board of Appeals meeting later this evening allowing for some of these properties to be subdivided, which is required prior to property transfer and recording. Due to the specialized work required for these acquisitions and pending subdivision, staff is requesting a sum of $10,000 to be utilized to pay for registered surveying services required for the preparation of the surveys, legal descriptions, and setting of iron monuments to delineate the new property lines. Proposed Street Improvements I 66th/I 67th Avenue is proposed to be reconstructed to. MSA standards, including a 9 ton design and 32 foot width; which would allow for parking on one side (a formal resolution is required for this parking restriction and attached to this case for consideration).
