LOS ANGELES (KTLA) -- The Los Angeles County Board of Supervisors agreed to raise fines up to $1,000 for throwing a football or Frisbee on any beach in the county.

A 37-page ordinance passed on Tuesday clarifies which beach activities are permissible and when.

The updated rules prohibit "any person to cast, toss, throw, kick or roll" anything other than a beach ball or volleyball during peak beach season -- between Memorial Day and Labor Day.

There are some exceptions for ball-throwing in pre-designated areas or when a person obtains a permit.

Additionally, playing water polo is allowed in the ocean.

The rules for ball-playing will be relaxed during the winter beach "off-season."

Officials say the rules are intended to prevent injuries to bystanders on busy summer days.

Another rule toward that end prohibits digging a hole deeper than 18 inches.

Exceptions can be granted for film and TV productions.
