Meeting Date: 07/14/2015 By: Bruce Westby, Engineering/Public Works Information Title: Adopt Resolution #15-07-175 Ordering Feasibility Report for 2016 Street Maintenance Program Division C, Andrie Street and 164th Lane Reconstruction; Improvement Project #16-00 Purpose/Background: Purpose: The purpose of this case is to adopt Resolution #15-07-175 ordering preparation of a Feasibility Report for the Division C improvements of the 2016 Street Maintenance Program, Improvement Project # 16-00, which involves reconstructing Andrie Street and 164th Lane between Alpine Drive and Jarvis Street. These streets measure approximately 2 miles in length in total. Figure 1 (attached) shows the proposed project scope. Background: Both Andrie Street and 164th Lane are part of our Municipal State -Aid Street (MSAS) system so MnDOT State Aid standards must be complied with during design. Both streets are classified as collectors, have traffic volumes less than 2,000 ADT, and have 30 mph design speeds. Based on these criteria, State Aid standards call for a minimum design width for on -road bicycle lanes of 5' to 6' (Staff proposes 6' for safety purposes), 8' parking lanes, and 11' to 12' drive lanes (Staff proposes 11' drive lanes to help keep street widths to a minimum). Existing Conditions — Andrie Street and 164th Lane were originally constructed in 1985. Both streets are 31' wide from back of curb to back of curb, and have pavement sections consisting of 2" of bituminous over 4" of class 5 aggregate base with bituminous berm curbing. Both streets received cracksealing and sealcoating improvements in 1999. The pavement sections on both streets are in poor condition and have Pavement and Surface Evaluation Rating (PASER) ratings of 2. This places them just slightly better than the pavement conditions on Garnet Street, 168th Avenue, and Jarvis Street, which all have PASER ratings of 1 but are being reconstructed in 2015. The pavement surface is exhibiting numerous types of deformation, but of particular interest is the significant raveling that is occurring along the gutter lines due to the frequent flow of water along the gutters. While some of this water is directly attributable to stormwater runoff from rain and snowmelt events, much of it is also due to the numerous irrigation systems being used along these streets. No off or on -road pedestrian facilities exist. Minimal storm sewer exists in the form of catch basins with concrete pipe leading to outlets to adjacent low areas. No public water supply or sanitary sewer utilities exist in this area of the City.
