Early voting is April 28 through May 6.Fort Worth and Arlington have busy ballots. There will also be council elections in Colleyville, Mansfield and Southlake, and school board elections in the Grapevine-Colleyville and Mansfield districts.The Arlington school board is submitting a $663.1 million bond package to voters. The board spent years setting impressive goals and got assistance from a local committee in determining what facilities are needed to meet those goals.The result is a proposal that would transform the district’s academic, arts, sports, transportation and technology programs.The Fort Worth City Council is putting a $292 million bond program before voters. It’s primarily transportation-related ($219.74 million) but also includes allocations for parks and community services, libraries, fire stations, municipal court renovations, facility expenses, and animal care and control.A six-candidate race for the District 9 seat on the Fort Worth council will draw a lot of attention.
