RE:	Project PW1302 – 9th Street (Avalon to Arkansas) Traffic Signal Improvements, Mill & Overlay, Sidewalk Improvements

Project Design

The 9th Street (Avalon to Arkansas) project includes a mill and overlay of the roadway between Avalon Road and Arkansas Street. After the roadway is paved new pavement striping will be placed to make a 3-lane corridor. There will be one thru lane and one bike lane in each direction as well as a center left turn lane on 9th Street. The turn lane addition is intended to help alleviate traffic accidents that have been prominent at both Emery and Michigan Street intersections due to left turn movements off of a busy 9th Street. New traffic signals and new ADA compliant sidewalk ramps will be installed at the 9th and Emery Road intersection. Also, sidewalk in poor condition will be replaced on the south side of 9th Street between Emery Road and Arkansas Street. Public Works staff designed this project in-house and will provide construction inspection.

In addition, city staff will be re-marking 9^th Street between Arkansas Street and Illinois Street to 3-lanes (one through lane in each direction with a center left-turn lane) with bicycle lanes. An evaluation of the peak-hour traffic at the intersection of 9^th Street and Maine Street found that under existing traffic volumes, this signalized intersection will operate at level of service “B” or better for east-west traffic; there will be no changes to north-south operations. Future changes may include pavement marking changes between Illinois Street and Indiana Street, in accordance with “complete street” concepts, that would provide bicycle lanes on 9^th Street from Tennessee Street to Avalon Road.

Project Funding

The project is being funded with federal-aid funds that cover ninety percent (90%) of the participating construction and construction engineering costs (inspection) with a project cap of $325,000. The remaining ten percent (10%) and all non-participating costs associated with the project are funded by the city from general obligation bonds approved in Resolution No. 7053 in the amount of $50,000. The project cost does not include the cost of engineering design or construction engineering services.  The project bid and construction engineering costs totaled $319,967.84.  Non-participating project costs totaled $13,780.87. The City’s contribution will be $45,777.65.
