Public Works Committee 5. 5. Meeting Date: 06/18/2013 By: Bruce Westby, Engineering/Public Works Title: Review of updated costs for reconstructing Andrie Street Background: Andrie Street's pavement is in very poor condition and should be reconstructed in the near future. Based on current pavement ratings this street should be next in line to be reconstructed following Garnet Street and 168th Avenue. In 2008, the city completed a Feasibility Study, prepared plans and specifications, and advertised for bids for the reconstruction of Andrie Street and 164th Lane. This included an alternate bid for constructing sidewalks as part of the project. The engineer's estimate to reconstruct the streets using concrete curb and gutter, bituminous pavement, and storm sewer was $1,270,000 and the low bid came in at roughly $900,000. The engineer's estimate for adding sidewalks was $300,000 and the low bid came in at $220,000. Ultimately, this project was never constructed due in large part to the controversy that arose over whether sidewalks should be constructed with the project, as well as some project funding questions. A copy of the 2008 Feasibility Study is attached for reference. Recently, staff was made aware of a renewed interest on the part of numerous area residents to reconstruct Andrie Street and 164th Lane. However, as in 2008 there appears to be little interest in constructing sidewalks with the project. On May 21st the Public Works Committee directed staff to update the estimated costs for reconstructing the streets as proposed in 2008, but without any sidewalks. In addition, the committee directed staff to include estimated costs for widening the pavement to accommodate on -road bicycle lanes for use by pedestrians and bicyclists. Since plans and specifications were completed for this project in 2008 this project could be moved forward quickly should the Public Works Committee and the City Council so desire, unless assessments are to be used to fund part of the improvements, in which case the corresponding public process per state statute 429 would need to be followed. No petition has been received requesting improvements since the original petitions were received in May of 2008. Notification: No notifications were provided to area residents as related to this item. Observations/Alternatives: Per Public Works Committee direction, staff updated the 2008 engineer's estimate to reflect today's estimated costs to reconstruct Andrie Street and 146th Lane, both as proposed in 2008 with a 32 foot wide road with 4 to 6 inches of aggregate base and 3'/2 inches of bituminous pavement with concrete curb and gutter and storm sewer, as well as to widen the pavement to accommodate on -road bicycle lanes which requires a 38 foot wide road. As with the 32 foot wide design, this option would also utilize curb and gutter and storm sewer, as well as the same pavement structure. It is important to note that both Andrie Street and 164th Lane are part of our Municipal State -Aid Street (MSAS) system so Mn/DOT state -aid standards must be followed. Minnesota rule 8820.9941 was therefore followed to determine the minimum design width for an on -road bicycle facility for urban reconstruction projects. This width is listed as 5 to 6 feet. Given the fact that large commercial vehicles have been seen using the streets to bypass the weight scales on Highway 10, staff is proposing to use a 6 foot bike lane. The following criteria apply to Andrie Street/164th Lane:
