The work will include 8 (eight) corings through the concrete pier deck of Municipal Pier. The exact location of the borings will be determined in the field based on site conditions. The core holes in the deck will be backfilled with concrete.
Drilling will be monitored for silt plumes during coring. Observance of silt plumes will require use of silt curtains or stopping of work until silt clears. The boring method is not anticipated to create impactful noise; however, the area will be monitored for impacts of noise on marine mammals. If impacts are observed, work will be altered to avoid the impact.
