Berms have been completed to help preserve the sand and keep beachfront homes safe in the Long Beach area. The project was completed in three phases.
Long Beach berms protect beaches along the peninsula
By John W. Scafetta
LONG BEACH — In response to a rash of rising high tides, the city of Long Beach’s Department of Parks, Recreation & Marine recently installed small berms along inner bay beaches to preserve the sand and safeguard surrounding homes in the area. “They’ve been doing this since the early 1990s. It happens whenever we have a significant high tide,” said Don Easterby, the city’s interim superin- tendent of Beach Maintenance. “This one is in relation to the high tides that we’ve experienced in June, July and August.” The project ran from June 9 to Aug. 19 and included three separate phases. The first phase took place between June 9 and June 19 and was in response to tides reported at 6.5 to 6.7 feet. An eight-day berm initiative in mid-July saw tides rise between 6.4 and 7.0 feet. The final phase ran from Aug. 4 to Aug. 13. Easterby considered all three phases a success, noting that construction aided in minimizing the immediate loss of sand. Implementing front end loaders,
city workers constructed undersized berms staked 2 to 3 feet in height and 3 to 5 feet in width. The heavy machin- ery pushed sand up from the toe of the beach at low tide to form a small sand wall along the outskirts of the shore- line. Easterby said that construction was a relatively quick process, noting that three workers recently completed a berm between 72nd and 60th streets in about 50 minutes. “We go down to the wet line, which would be the high tide line at low tide, and we push up whatever material we have available to us,” Easterby said. “Then we build this very small berm.” Easterby said the summer project’s
construction came at the request of the community, adding that a berm is typically present for most of the year on the east beach, near the outside of

the peninsula, between 72nd and 54th streets. The berms are built through the city’s general maintenance budget, but Easterby said the project is essen- tially the utilization of man hours. “Without the berm, it floods the beach and it makes it very difficult to enjoy,” Easterby said. “It also causes a little bit more erosion then we would like to see. If we don’t try to salvage some of the sand, it picks up in the current. By building the little berm that we have, we’re able to maintain what beach we have left down there.” But with residential dwellings standing just 50 to 100 feet behind the berms, flooding has become a real threat. On July 6, a high tide breached the
sand berm at Ocean Boulevard and 55th Place, but no damage was report- ed. Easterby said workers quickly responded to the breach and were able to patch it. While residents dodged a bullet, the peninsula hasn’t always been as fortu- nate. In early March, 20 homes along the
Long Beach peninsula were damaged when high tides and heavy surf eroded a protective berm, causing flooding between 66th and 72nd streets. The high tide was reported at 5.52 feet. Easterby expects berm construction to pick back up at the end of the year.
