This proposed realignment will increase the cost of the overall project. As a result, for the purposes of this report, we have evaluated the realigned S. Owasso Blvd as well as a proposal to reconstruct the street in its existing alignment. . Existine alienment: This proposal is the reconstruction of the street on the current alignment. The reconstructed street would include some traffic calming through medians, stop signs and street tree planting. Stop signs are proposed at both the Galtier Street and Western A venue intersections. A median would be constructed between Farrington and Marion Streets openings to allow for left and right turning movements into the neighborhood. Street trees would be installed on both sides of the road. The addition of landscaping close to the edge of the road and medians can assist in making the road "feel" narrower. This can help reduce traffic speeds. . Realienment: This proposal would realign the road through the city parcels located south of the road between Matilda and Marion Street. Due to organic soil deposits in this area, the new street construction will have additional costs associated with it. These costs effect both the construction and longevity of the new road. There are two methods that we can use to build a road on these soils. One method is to surcharge the soils; in this method, the organic soils are left in place and compressed for a number of months. Another way to do this is through excavation, this would be the removal of the full depth of organic soils and the reconstruction of the road subbase. We have estimated the up front construction costs for both of these construction alternatives, and will identifY the long term impacts to the street. Additional geotechnical engineering and soil stabilization will be necessary to construct the road in this alignment. This proposal also impacts the pathway and storm sewer improvement costs. The curve in the road would facilitate the Ladyslipper Park master plan as well as potentially reducing the speed of the traffic on this stretch of road. 2. Sidewalk: The neighborhood was very concerned about pedestrian safety along this segment of road. As a result, we are proposing to construct a sidewalk along the entire length of the project. This sidewalk will be constructed of concrete when adjacent to residential property and bituminous when adjacent to public property. Transitions between material will occur at logical locations such as street Project P-ST-SW-05-06 S. Owasso Boulevard Reconstruction Feasibility Report 19
