After about three years of working as North Bay Village’s Public Works director, Sam Zamacona has resigned from his post.

“I want to thank you for the opportunities that have been extended to me during my time with this village,” he wrote in his resignation letter dated Jan. 16. Zamacona did not list reasons why he is leaving his job with the village.

His resignation is part of a major shuffle of the village’s staff, in which two current employees were promoted to other positions and three new employees were hired. The changes are the result of officials budgeting for new staff positions for the current 2012-2013 fiscal year.

“We are hoping that the new additions to our team will allow us to … better serve the needs of our residents on a daily basis,” human resources director and Deputy Village Manager Jenice Rosado wrote in an email to The Miami Herald.

A front-desk clerk of more than five years, Lucy Palacios, was promoted as the Finance Department’s accounting clerk, a position with an annual salary of $41,000, according to Rosado.

Leilani Towne Calzadilla was hired to fill the front-desk clerk position at an annual salary of $37,000. Calzadilla has more than nine years of experience in customer service and clerical work in the legal field, Rosado said. According to Calzadilla’s Facebook page, her most recent employer was Greenberg Traurig, an international law firm.

The human resources and special-events-coordinator position was also filled through an internal transfer. Ana Deleon, who has worked for more than five years as the village’s building and permits clerk and also helped out with special events, was promoted. While the HR/special-events-coordinator position was budgeted for an annual salary of about $31,600, Deleon’s salary will be $39,000. Since she is being promoted from her previous job, which had an annual salary of $38,000, the city cannot give her a pay cut, finance director Bert Wrains said.

The cost increase is partially offset by reducing the salary of the new building and permits clerk, he added.

Elena Grek was hired to the position at an annual salary of $36,000. Previously, she worked for about three years as Sunny Isles Beach’s building and permits clerk, said Rosado.

Officials are also finalizing the hire of an executive assistant to Village Manager Dennis Kelly and to the commission. The new hire will receive an annual salary of about $46,000. The village will not publicize the chosen candidate’s name until a background check is complete, Rosado said.

Following Zamacona’s resignation, Rodney Carrero-Santana is serving as the interim Public Works director. Carrero-Santana is an engineer with C.A.P. Engineering, a corporation that provides engineering design and construction management services to the public and private sectors.

The village is seeking applications for the Public Works director position.

Interested candidates may submit a résumé and an application to Rosado by Feb. 18.
