These initiatives include water supply planning and development of alternative water supplies, such as conservation, reuse, and aquifer storage and recovery. They also include implementation of the District’s springs and Ridge lakes restoration initiatives and the watershed management, minimum flows and levels, Facilitating Agricultural Resource Management Systems (FARMS) and Surface Water Improvement and Management (SWIM) programs.

Alba Más

Regulation Division Director Alba Más


Alba E. Más was appointed director of the Regulation Division. Más is responsible for permitting and compliance activities in the District’s 16-county area.

Más has worked at the District for more than 20 years and has served since 1998 as the director of the District’s Tampa Regulation Department. She has extensive experience with all aspects of water resource regulation, including environmental resource permitting, water use and demand management, well construction, regulatory compliance, enforcement and rulemaking.


The reorganization of the District’s executive leadership team is part of an overall restructuring that will increase efficiencies, reduce operational costs and meet the District’s core mission responsibilities in the areas of water supply, flood protection, water quality and natural systems.

“As an organization, we have to get leaner and more efficient,” said new Executive Director Blake Guillory. “The more quickly we can get right-sized for our budget and workload, the faster we can move forward, secure in our jobs, to meet the water resource challenges of this District.”

The proposed restructuring aims to increase the District’s efficiency and reduce costs and is expected to save the District more than $15 million per year.

The restructuring plan would reduce the District’s 768-member staff by at least 150 positions. District staff have been offered a voluntary separation plan; however, if the voluntary efforts don’t produce the necessary reductions, the District will have involuntary layoffs in January or February to meet its goals.

“We are blessed with smart and talented people. Unfortunately, we are caught in a situation driven by economic conditions,” Guillory said. “We need to be as thoughtful and helpful as we can during this process, while also serving the taxpayers of our area.”
