Among the cities in Palm Beach County holding elections is Delray Beach, where four candidates are vying for two seats and two key votes on a commission known for its frequent 3-2 decisions.

The winners will serve three-year terms for the at-large seats. Seat 2 Commissioner Juli Casale, 54, wants a second term but is facing a tough challenge from Rob Long, 38, who as a former member of the city’s Planning and Zoning Board, often voted to support development projects that Casale opposed.

In the Seat 4 race, former Commissioner Angie Gray, 57, and retired teacher Angela Burns, 66, are vying to replace Commissioner Shirley Johnson, who can’t run due to term limits.

There also are referendum items on the ballot. In addition to voting for candidates in two contentious City Commission races, Delray Beach voters will be asked to consider two bond referendums, $100 million for public safety and $20 million for parks and recreation.

Boca Raton has no candidates on the ballot, as the mayor and City Council races are unopposed, but voters will be asked to decide whether to extend the terms of their elected officials for a year. Mayor and City Council seats would increase from three years to four years if approved.

In addition to Delray Beach and Boca Raton, other communities having an election are Atlantis, Belle Glade, Boynton Beach, Highland Beach, Hypoluxo, Juno Beach, Lake Clarke Shores, Lake Park, Lantana, Mangonia Park, Ocean Ridge, Palm Beach Shores, Palm Springs, South Bay and Tequesta.

• In Deerfield Beach, two incumbents face challengers. Incumbent Michael Hudak is running in District 1 on a platform of water management, stormwater protection and resiliency efforts in this coastal city. His opponent, Maria LoRicco, said traffic and crime are important concerns. In District 2, incumbent Ben Preston, the city’s first Black firefighter hired in 1974, helped get Juneteenth recognized as a city holiday. Preston has two challengers including Terry Scott, a political activist, who lost narrowly to Preston four years ago. The other candidate is Darlene Swaffar, who ran for Congress last fall and lost in the Republican primary. The seat was won by Democrat Jared Moskowitz. Also, in a referendum, voters will be asked to vote for or against the sale of a 3.75-acre swath of public property for $6.5 million. City officials said they plan to build a “multi-use development” with workforce housing, retail and restaurant space, and a hotel.
• Coconut Creek: District A: Becky Tooley, Jeffrey Wasserman; District D: John Brodie, Alfred Delgado, Nancy Gayle Fry. The majority vote-getters win the race. Also in Coconut Creek, a referendum item: A charter change amendment would require a vacancy on the City Commission be filled by voters in an election, and not by appointment by other elected officials.
• Hillsboro Beach: Three seats are open: Vincent “Vinnie” Andreano; Barbara Baldasarre; Richard Crusco; David Anthony Ravanesi. Voters will pick up to three. The three with the most votes will serve.
