Suburban Island

Originally and now called Credit Island, Suburban Island was once a highly sought recreational area.

History
In May of 2010, the city of Davenport received a grant from the State Historical Society of Iowa to conduct an archaeological study of one of the Mississippi River islands near the Iowa shoreline. The eventual goal was to get Credit Island listed on the National Register of Historic Places. Here is some of the results of that study:

In August of 1814, future president Zachary Taylor battled British troops on or around the island. Much later, the island was purchased by private owners, renamed Suburban Island, and was used as a recreational spot for swimming and sports prior to World War I. The city of Davenport bought the island in 1918, and held a naming contest: Credit Island was the clear winner. A golf course eventually replaced the picnic grounds and swimming facilities.

In the 1890s, amusement parks opened up on Campbell's Island, Prospect Park, and Black Hawk State Park on the Illinois side and Suburban Island and Schutzen Park on the Iowa side.

In the fall of 1904, the name of Credit Island was changed to Suburban Island because of the railroad that ran to the island. In 1918, the City of Davenport bought the island. Davenport Park Board meeting minutes started being documented in 1918, and no mention of the amusement park was made so it likely was gone by then.

The island also had a Figure 8 Roller Coaster 1905 until an unknown date.
