Meeting Date: 10/25/2016 By: Bruce Westby,Engineering/Public Works Information Title: Public Hearing-Adopt Resolution#16-10-202 Adopting Assessment Roll Certifying Andric Street and 164th Lane Reconstruction Assessments; Improvement Project#16-00 Division C Purpose/Background: Purpose: The purpose of this case is to adopt Resolution 416-10-202 adopting the assessment roll certifying Andrie Street and 164th Lane Reconstruction assessments; Improvement Project 16-00 Division C. Background: Improvement Project 916-00 Division C involved the reconstruction of approximately 9,963 linear feet(1.89 miles) of public streets in the Northfork development including Andric Street from Alpine Drive to 164th Lane (approx. 6,312 feet),and 164th Lane from Andric Street to Jarvis Street(approx. 3,651 feet). Attached is the title sheet of the construction plans which shows the location and scope of the improvements. Both of these street segments are included in the City's Municipal State Aid Street system therefore all improvements to these streets are required to meet minimum Minnesota Department of Transportation(MnDOT) State Aid standards. Previous Conditions Andric Street and 164th Lane were constructed in 1985 using bituminous pavement and bituminous curb at a width of 31 feet from back-of-curb to back-of-curb. A Geotechnical Report was completed in conjunction with the Feasibility Report. The findings of the Geotechnical Report were based on results gathered from 22 soil borings completed to depths of 10 feet. The soil borings showed that the original bituminous pavement sections along the improved streets varied in depth from P/2 to 4 inches,that the aggregate base varied in depth from 3 to 7 inches, and that the subgrade soils generally consist of sands and silty sands. Several areas along these streets were relatively flat, and the storm sewer system was generally insufficient to effectively drain stormwater and irrigation system runoff from the streets. This resulted in an accelerated deterioration of the bituminous pavement and curbs. Both streets were sealcoated in 1992 and 1999,but no overlays were completed on the streets. In recent years both streets required a significant amount of pothole patching. The pavement condition of both streets was reviewed by City staff in the fall of 2015 and both streets were assigned Pavement and Surface Evaluation Ratings of 2. This meant the pavement sections were past the point of considering mill and overlay improvements, and that a complete reconstruction was required instead. Improved Conditions Both streets were reconstructed to a width of 33 feet from back-of-curb to back-of-curb,which is 2 feet wider than the previous street width. This width was ultimately approved by the City Council based on input received from
