City Administrator Recently the Marshall City Council selected architectural and engineering firm Stockwell Engineers to guide the city through the aquatic center design process. The Marshall Aquatic Center has served the residents of Marshall and surrounding communities for more than 50 years–a long time for a community recreation facility. The current facility is showing its age and has numerous deficiencies in code compliance, operations, customer experience and maintenance costs. The existing Marshall Aquatic Center includes three vessels: a diving pool with 1-meter and 3-meter diving boards, a lap/ general use pool with a waterslide, and a wading pool. It also includes a bathhouse and concessions building. The original facility was constructed in 1960s.
