Over the past several years, security at the Rose Parade and the Rose Bowl Football Game has been increased due to the rise of global terrorism.

This year is no exception.

The increased security will also focus on elevated areas along the parade route in response to the shooting in Las Vegas during a music festival which left 58 people dead and hundreds injured.

Security will be provided by local, state and federal authorities, including the California Highway Patrol, the Los Angeles Sheriff’s Department, the Los Angeles Police Department, the Department of Homeland Security and the US Secret Service.

No-fly zones over the parade and the Rose Bowl have been imposed by the Federal Aviation Administration (FAA). Drones are also prohibited at the parade and the game.

An unknown number of undercover law enforcement agents will also be on the parade route and at the game.

Besides the regular police presence, there will be a dozen so-called rapid response teams at ground-level and air surveillance that can monitor the entire parade route.

No known threats have been made against either the parade or the game, authorities have said.

Ironically, as security increases to an all-time high, arrests made between noon on Dec. 31 and 6 p.m. New Years Day in Pasadena are at an all-time low. At the last parade, police arrested seven people for public intoxication and trespassing.

Also in the interest of security, police will close the streets on the parade route two hours earlier. Starting at 10 p.m., Colorado Boulevard will be shut down from the beginning of the parade route at Colorado and Orange Grove boulevards to Sierra Madre Boulevard in East Pasadena.

Temperatures are expected to drop into the mid-40s on New Year’s Eve and reach 70 degrees on New Year’s Day.

Parade goers can set up chairs starting at noon on New Year’s Eve. Unoccupied chairs are not allowed and will be removed.

Along the parade route, tents, sofas and boxes of any type that can be used as stools or seats are prohibited.

Open containers of alcohol are illegal on public streets, sidewalks and all other public areas and violators may be cited or arrested. Police will also crack down on use of silly string, as well as marshmallow and tortilla throwing along the route. Umbrellas are also banned.

At the 2016 Tournament of Roses events, security was increased after the terror attack in San Bernardino, when an ISIS sympathizer opened fire during a Christmas Party.

Syed Rizwan Farook, 28, and his wife Tashfeen Malik, 29, killed 14 people and wounded 22 others attending a San Bernardino County Department of Public Health holiday party. At the time, federal authorities ranked the Rose Parade and Rose Bowl Football Game a “Level 1” Special Event Assessment Rating (SEAR), giving city officials full support from the federal government.

For the 2017 parade, officials put up barricades after the attack in Paris where three suicide bombers struck outside the Stade de France in Saint-Denis during a soccer match. That attack was followed by several mass shootings at cafés and restaurants and a suicide bombing that left 130 people dead.

Over the past several years, activists and social groups have attempted to disrupt the Rose Parade to make statements on issues ranging from marriage equality and human rights abuses in China to the treatment of African Americans at the hands of the police.

Over the past decade, the parade route has also been used to promote a number of causes. Last year, a skywriter wrote “America is Great, Trump is Disgusting” in the brilliant blue sky over the parade route. The man did not break the law because the ban on airspace only extends a quarter-mile above the route.

In 2015, seven members of the group Black Lives Matters (BLM) were detained for allegedly trying to disrupt the parade. BLM members waved signs decrying recent shooting deaths of black men by police. Members of the group attempted to enter the parade route with a large banner that read, “This is our year. This is not a moment. This is a movement.”
