Option 1 is to close New Vineyard A venue between Pietronave Lane and Machado Place during construction, and use Old Vineyard Avenue as a traffic detour. This option will allow the contractor to maximize the work effort per day and increase production, with an estimated time for project completion of 2.5 months, although staff would attempt to shorten this time period if construction activity exceeds the project schedule. A component of this option is to perform minor road repairs to the proposed traffic detour on Old Vineyard Avenue. Repairs include refreshing roadway lane striping, performing shrubbery and tree trimming work along the edge of the roadway, and provide minimal pavement repairs on Old Vineyard A venue in advance of the removal of the traffic roundabouts. These repairs will be completed by City crews prior to use of the old roadway as a traffic detour route. Option 2 is to maintain vehicular traffic on New Vineyard Avenue during construction. Option 2 would have to be done in three phases. Phase 1 would consist of building the northerly 10- foot roadway section and removing the roundabout approach islands on the side streets. Phase 2 would consist of diverting traffic onto the newly built lO-foot roadway section for westbound traffic and striping the existing roadway section between the southerly edge of the newly constructed lO-foot roadway section and northerly edge of the concrete traffic circle, for eastbound traffic. This configuration will not allow westerly left turn movements off Vineyard Avenue onto side streets or left turns heading westerly from side streets. During this phase, the reinforced concrete traffic circles would be removed, along with the remaining roundabout approach islands. The final phase would consist of installing striping and pavement legends on the pavement surface for the ultimate roadway configuration. This option decreases daily work production by constraining the construction sequencing and limiting the available workspace in which the contractor can work. These restrictions increase the contractor's duration and responsibility for maintaining a safe work site for construction workers and continued use by the public. The estimated project construction time for this option is 5 months. Discussion Staff is recommending the implementation of option 1, closing New Vineyard A venue and using Old Vineyard Avenue as a construction detour. As mentioned above, this option will allow the contractor to maximize work effort and complete the new roadway improvements in 2.5 months, reducing construction costs, the impacts to the community, and increasing the quality of work.
