The New York Police Department is planning a heavy presence for the city’s July Fourth celebrations.

NYPD chief spokesman Paul Browne said Wednesday the department’s entire air and sea fleets will be deployed on Thursday: That’s seven helicopters and 16 boats.

He said Harbor Unit boats will help direct traffic jams after the Macy’s Fourth of July Fireworks 2013 show.

Browne said that before the show begins over the Hudson River, police will conduct sweeps of underground garages and surrounding streets. He said counter-terrorism officers will remove all trash cans from the viewing areas and use dogs that can detect explosives and explosive residue.

Browne said 38 mobile cameras purchased after the Boston Marathon bombing will be fixed to light poles and other areas to monitor the crowd.
