Nearby neighbors may already notice that sound walls and environmental protective fencing have gone up at the perimeter of the work area. Noise walls were also installed to isolate noise within the work area. The contractor will continue to abide by the City of Fremont’s local noise ordinance.
To ensure that dust is controlled, the environmental team and the contractor work together to assure that stockpiles are covered with plastic and active areas are watered to suppress dust in active areas.
To ensure dust control measures are met, stockpiles are covered with plastic tarps and weighed down with sand bags. These piles are also watered to minimize dust.
It is also imperative that the contractor meet certain erosion and sediment best management practices to protect the nearby creeks and the city’s storm drains. For example, the environmental team monitors the contractor to ensure the implementation of the project’s Storm Water Pollution Prevention Plan that requires storm drains and drainage outlets to be protected. In addition, track-out controls are in place, such as the installation of rock placed at construction entrances and exits. Finally, sweeping of the roadways take place regularly.
Track-out controls limit dust-related concerns. An example of a track-out control is the installation of rock that is laid at the entries and exits of each work area. This rock limits the amount of dust kicked up by trucks.
