prevention plan will be created during the design phase of this project. Immediate turf establishment in areas of soil disturbance will be required such as placing seed and erosion control blanket. After street and utility work is completed, sod will be placed as the permanent turf establishment in all disturbed areas. The City in coordination with the watershed district will closely monitor all erosion and sediment control measures throughout the construction process. The selected contractor will be required to install all preventative measures and maintain them as required by the City and RWMWD. TRAFFIC CONTROL Traffic from outside the neighborhood would be impacted by the utility extension work along Keller Parkway. A construction project of this magnitude will result in inconvenience and disruption to the neighborhood and its residents. Signage will be installed noting that streets are for local traffic only. Detour routes may be required for through traffic on Keller Parkway between Kohlman Lane and Arcade Street during the proposed utility extension work. The majority of residents only have one in /out access. A detailed construction phasing plan along with informative mailings and web updates will be necessary in order to minimize inconvenience to residents. Emergency access for vehicles will be available 24 -hours a day throughout the project. During periods of time, however, some segments of the project may not be passable while certain work is being executed. In these instances, notification will also be given to residents and a plan will be prepared to accommodate emergency vehicles. Residents with concrete curb work, or concrete driveway apron replacements, will not be able to use their driveways during the week the concrete is curing. During that time, Maplewood police will be notified in order to add patrols while residents are required to park on the streets. The traffic control plan will reflect Mn /DOT standards.
