City commissioners on Wednesday night awarded the $4 million contract to Houston-based SER Construction Partners.
The agreement includes repairs to the closed dike and rebuilding of the pier road, which was washed away when Ike made landfall in September 2008.
Texas City last month received $2.6 million from the federal government to help fund repairs.
Mayor Matt Doyle says when the dike reopens the city will start charging a per-car fee for access.
Texas City will be using state grant funds from the Texas Parks and Wildlife Department to help pay to fix the boat ramps.
