The city will close Mokule'ia Beach Park overnight beginning June 16, the city Department of Parks and Recreation said yesterday.

The decision to close the park from 7 p.m. to 7 a.m. daily follows the recent demolition of a deteriorated restroom facility and recommendations for night closure by the North Shore Neighborhood Board and the city's Parks Board, the city said.

The city last year started looking at North Shore beach parks, including Mokule'ia, for aggressive maintenance work partly aimed at preventing homeless campers from taking root.

While the homeless population on the North Shore is small compared with the Wai'anae Coast — where hundreds of beach dwellers were displaced during city park improvement projects since 2006 — some residents have expressed concerns about homeless people taking over some North Shore beaches.

The park's shoreline will remain accessible to night fishermen during the closure hours.

The beach park's restroom facility was torn down last month because it had deteriorated to the point of becoming a safety hazard, the city said.

Officials are planning another facility to replace it, but construction is not expected to begin for some time, said Department of Parks and Recreation director Les Chang. In the meantime, portable toilets are available for daytime park users, he said.
