Police and state officials will be enforcing parking and alcohol restrictions on land and sea in Windward Oahu this Memorial Day weekend.

An alcohol ban is in effect for the Kaneohe Bay sandbar, also known as Ahu o Laka, and parking is not allowed on most streets in Lanikai through Monday.

The state Department of Land and Natural Resources enforcement officers will be at Heeia-Kea small-boat harbor and at the sandbar in Kaneohe Bay to ensure compliance with the alcohol ban. They will also be checking operator permits, vessel registration and safety gear requirements.

The law applies only to three-day holiday weekends, including Memorial Day, Independence Day and Labor Day. It was initiated in 2012 after numerous reports of problems caused by intoxicated boaters.

Meanwhile, parking restrictions that were used in Lanikai over the Presidents Day weekend in February will be in effect over the Memorial Day weekend.

These temporary measures are also being used to collect data on traffic volumes and congestion, city officials said.

Vehicles will not be allowed to be parked on the unimproved sidewalk on the right side of the road along the one-way Lanikai loop.

The Lanikai loop includes Alapapa Drive and Mokulua Drive, where a bike lane runs along the right side of both streets. Parking is always prohibited in the bike lane, with a potential fine of $200.

Motorists should also not drive on the bike lane, stop and/or unload on a bike lane, the city Department of Transportation Services said, because bike lanes are reserved for bicyclists. This holiday weekend, barriers will be placed adjacent to the bike lane on the Lanikai loop notifying motorists that no parking is permitted on the right side of Alapapa and Mokulua drives over the Memorial Day weekend.

“The city is taking this action because traffic congestion in Lanikai on weekends, especially on three-day weekends, is a safety issue,” said Director of Transportation Services Mike Formby.

“During severe traffic congestion caused in part by illegally parked cars, pedestrians and bicyclists are forced into the roadway and emergency first responders have difficulty getting into and out of Lanikai.”
