Memorial Day Weekend is the unofficial start of the summer in New York City, as city beaches open for the season.

To ensure a safe summer, city leaders announced a multiagency plan that includes extra eyes in the sky, sea and land.

Police Commissioner Jessica Tisch says dynamics of public safety shift during the summer months, historically resulting in an uptick in crime.

This year, it launched a summer safety deployment in an effort to change that narrative.

Tisch says the NYPD established 70 violence zones in 57 precincts across the city. In those neighborhood zones, there will be an additional 1,500-foot patrol officers during the evening and overnight. Officers will also be deployed in public housing developments and subway stations.

"If you live in one of these neighborhoods, you will certainly feel this plan. You'll see the cops on your block, on your walk home, the places that matter most," said Tisch.

As for noisy neighbors in the street and loud music, the city says there will be a zero tolerance for late night noise. The NYPD will be closely monitoring 311 complaints to address quality-of-life concerns on the weekends.

"Keeping New Yorkers safe takes teamwork, and this summer, that teamwork is on full display," said New York City Deputy Mayor for Public Safety Kaz Daughtry. "Our public safety agencies are using every tool we've got to protect people — on the ground, in the water, and in the air. It's another example of how this administration works as one team, with one mission, to deliver real results for New Yorkers."

During beach season, lifeguards will be on duty daily from 10 a.m. to 6 p.m.. Swimming is not allowed when lifeguards are off duty and in closed sections that are marked with red flags. The city says there will be enhanced monitoring protocols for shark activity including drone teams assisting with surveillance and rescues that can drop flotation devices to swimmers to assist in rescues.
