Located between S. Peoria St. and E. Jewel Ave., at the confluence of Westerly Creek and Jewel Tributary, Utah Park functions as a popular community park for the City of Aurora as well as a flood-control facility. The $5.8 million park previously was a large stormwater detention basin with a muddy lake at the bottom and the creeks channeled underground in pipes. Low-lying areas, including a ballfield, regularly flooded when it rained. In 2006, Design Concepts developed a master plan and followed with construction documents that hid the site’s function, transforming it into a very attractive park and better functioning detention basin with contoured topography, naturalized streambeds, and two new ponds, as well as active recreation features. The 47-acre site now embraces two natural creeks that flow into the park. Construction began in November 2006 and was complete in August 2008.
