Rock Island • At a study session on March 26, the Rock Island City Council received a report from the Sylvan Slough Task Force, which is charged with updating a 1989 plan for the area. The new report recommends, among other things, expansion of the Quad City Botanical Center to the area just east of Government Bridge for a children's garden; development of the Sylvan Slough as a "naturalized exhibit (river and woods) and an extension of the Botanical Center"; creation of a "railroad museum" along the Iowa Interstate and Burlington Northern railroad yards; development of a "public access site to the river" in the industrial area behind and to the east of the QCIC plant; and creation of a baseball stadium for Augustana College between 5th and 6th avenues and 39th and 40th streets.
