r" Ile Road Reconstruction of Olive Street FROM PRAIRIE AVENUE TO TUCKER DRIVE TECHNICAL UNDERSTANDING The existing site conditions consist of several businesses throughout the project limits. Most of these businesses are located on the northern portion of the project, while the south end is mostly residential, with a few scattered businesses. The roadway to be reconstructed is currently Portland Cement Concrete Pavement (PCCP), except for the very south end which is asphalt. Currently, the project is slated for a November 10, 2020 letting. The scope of the work will include the reconstruction of the pavement on Olive Street from 100 feet north of Prairie Avenue to approximately 390 feet south of Tucker Drive. The typical roadway will consist of two 11- foot travel lanes with a 12-foot auxiliary turn lane along the centerline. A majority of the roadway cross-section will be composed of 10-inch QC/ QA PCCP on compacted stone subbase on Type III treated subgrade. In order to accommodate street parking, the plans include an eight -foot parking lane along the west side of the roadway from Ewing Avenue to Calvert Street. Upgrades to the existing traffic signal located at the Prairie Avenue (SR 23) intersection will help to improve traffic flow. In addition to the roadway improvements, the project will coordinate with Norfolk Southern Railroad contractors as they replace the at -grade crossing. Additional railroad work will include the installation of new signal arms and a pedestrian gate and handrail system. Pedestrian -friendly improvements include a newly constructed concrete shared -use path which will be eight-feett in width, allowing it to accommodate multiple forms of pedestrian traffic. The existing concrete sidewalk will be replaced with a new five-foot concrete sidewalk. ADA- compliant ramps and crossings will be placed in planned locations. For added safety, new ornamental light poles with LED lighting will be installed from Prairie Avenue to just north of the Norfolk Southern Railway crossing. Supplementary construction items of note are the total length of the project is slightly less than % of a mile and construction will take place in two phases, while maintaining one-way traffic. Multiple driveway approaches, including both residential and commercial will be affected by both phasing and when the drives are reconstructed. To increase the necessary site drainage, just over 6,300 feet of storm sewer will be installed, helping to illuminate combination sewer concerns. Due to the significant roadway construction, erosion control and site drainage must be monitored, anticipated, and controlled at all times. We expect multiple temporary erosion control measures will be implemented and maintained throughout construction. Silt fence, riprap, check -dams, rock berms and sediment traps, temporary seeding and mulching, and dewatering stations will be incorporated throughout the project limits.
