Tisbury building and zoning inspector Kenneth Barwick retired this week after more than 30 years on the job.

Town administrator Jay Grande confirmed the retirement during the regular selectmen’s meeting on Tuesday. Mr. Barwick submitted a formal letter on July 25. His retirement was effective on Thursday.

“After much considerable thought, discussions with my wife, family members and family counsel, it is with very deep sadness and not a single regret that I formally submit my two weeks’ notice to retire,” Mr. Barwick wrote in part.

On Tuesday, selectmen confirmed a new local building inspector, Ross Seavey. The town has begun advertising for the position to find a new department head.

In other personnel changes, Ray Tattersall is no longer the head of the Department of Public Works and is now the town electrician. Kirk Metell, formerly the town facilities manager, is now acting head of the DPW.

Wastewater superintendent Paul Ernst has also resigned and will leave his position in mid-September, Mr. Grande said.
