· Measures to be implemented to minimize dust, traffic, and transportation impacts, erosion, mud, noise,
and other characteristics.
The greatest dust causing activities (earthwork), is anticipated to be done during historically wet
months (Oct – Nov), so dust control measures are expected to be low. However, dust will be
mitigated through garden houses as required.
Erosion control silt fence, hay, and catch basin “socks” will be utilized for onsite erosion control.
Contractor will also follow Erosion control measures detailed and identified in the Civil TESC plan.
High noise-generating activities will follow the following schedule:
Activity When Duration
Sawcutting 8AM - 4PM Varies
Jackhammer 8AM - 4PM Varies
Demolition 7AM - 4PM Varies
Compactors 7AM - 4PM Varies
Power tools (saws, nail guns, compressors, etc.) 7AM – 4PM Varies
· Any special hours proposed for construction hauling (i.e. weekends, late nights)
Due to relatively small size of project, there won’t be any material deliveries of significant size or carrier

that will require special hours for construction hauling.
· Preliminary traffic control plan.
There isn’t any work being done in City ROW. Therefore, the need to reroute or slow traffic will not be
required. All work will be constructed and staged within the property lines.
