Some new decorations were hung along the Principal Riverwalk Friday.
Volunteers hung more than 5,000 flags along the entire length of the path to remind people that Earth Day is approaching.
Each flag was designed by school children, Principal Financial employees and community members and each one holds a wish for environmental improvements.
The city is hosting a flag making event on April 17th at the new Hub Spot on the Riverwalk near the Court Avenue Bridge.
Principal Financial is paying for the project.
