Mayor Alameda appoints new directors for Environmental Management, Public Works departments

Hawaiʻi County Mayor Kimo Alameda has appointed new leaders to two major county departments, with Daniel Girvan replacing Wesley Segawa as director of the Department of Environmental Management, and Segawa transitioning to head of the Department of Public Works.

Both appointments took effect on Monday and will now move to the County Council for confirmation.

Neil Azevedo, who has served as acting Public Works director since March 31 with the retirement of Hugh Ono, will continue with the department as deputy director.

Girvan has nearly 30 years of experience overseeing large construction projects in Michigan, where he served as president and chief engineer at Resource Engineering, Inc

Girvan’s technical expertise and management background made him “an outstanding choice” to guide the department responsible for wastewater, solid waste and other environmental services, Alameda said in a press release.

Segawa, who has led the Environmental Management department since December 2024, is returning to a field that better matches his extensive experience in engineering and construction management.

Before joining the county, he ran Wesley R. Segawa and Associates, Inc., working on both public and private infrastructure projects.

“I want to thank Wesley Segawa for his steady leadership and dedication,” Alameda said. “His transition to Public Works is a natural progression… With both Daniel and Wesley in these key roles, our infrastructure will be in excellent hands.”
