CC Regular Session Meeting Date: 08/23/2022 Submitted For: Joe Feriancek, Engineering/Public Works By: Joe Feriancek, Engineering/Public Works 7. 5. Information Title Adopt Resolution #22-201 Ordering Plans and Specifications for 167th Avenue Reconstruction, Improvement Project #23-04 Purpose/Background: Purpose: The purpose of this case is to adopt Resolution #22-201 ordering plans and specifications for 167th Avenue Reconstruction, Improvement Project #23-04. Background: City Improvement Project 23-04 proposes to reconstruct 167th Avenue between Nowthen Boulevard (CSAH 5) and Saint Francis Boulevard (TH 47). The street totals approximately 6,000 linear feet (1.13 miles) in length, and varies between 40-foot wide rural section (0.97 miles) and 48-foot wide urban section (0.16 miles). A full shoulder/parking lane exists on both sides of the street, for the entire length of the street. A figure showing the project scope and a street segment summary is attached to this case. On June 14, 2022, the Ramsey City Council accepted a proposal for a topographic survey of the project area from Bolton & Menk. Staff is submitting a proposal for a geotechnical report with a separate resolution. 167th Avenue was included in the Ground Penetrating Radar (GPR) Pavement Evaluation perfoiined by Braun Intertec. This data provides bituminous and aggregate base thickness information. The GPR data is included in the street segment summary attached to this case. 167th Avenue is a Municipal State Aid (MSA) street, and must be designed to MSA standards. Staff is proposing to generally leave the street at the current 40-foot rural section width, and 48-foot urban section width. The existing curb and gutter is generally in good shape and is proposed to have spot repairs done as necessary. The street will also be required to meet an MSA 10-ton design standard. Traffic counts taken in 2021 on 167th Avenue east of Nowthen Boulevard found an Average Daily Vehicle (ADT) count of 1,637, and counts taken west of TH 47 found an ADT of 2,332. Based on these traffic volumes, Staff is estimating the required pavement section will be approximately 9 inches thick, but review of the proposed geotechnical report will be necessary to determine the existing sub -base materials below the pavement. If sub -base materials are adequate, this street may be a good candidate for the Stabilized Full -Depth Reclamation (SFDR) project, similar to what was performed on Sunwood Drive between Ramsey Boulevard and Bunker Lake Boulevard in 2017, and on Variolite Street between Alpine Drive and 173"d Avenue in 2020. Staff has received numerous inquiries from residents if additional bicycle and pedestrian facilities will be added with the reconstruction project. Staff is investigating the possible alternative for adding an off-street trail along 167th Avenue, or creating on -street facilities. Currently, the 8 to 10-foot wide shoulders are a shared use for bicycles and pedestrians. Any improvements must meet both MSA standards and ADA standards. Municipal water exists from Quicksilver Street (approximately 650 feet west of TH 47) to Nowthen Boulevard. Sanitary sewer does not exist in the project area.
