The Gage Park Improvement Authority (GPIA) was created by a vote of Shawnee County residents on November 8, 2022. Shawnee County residents voted in favor of the ballot question: "Shall a Gage Park Improvement Authority be created and supported through the levy of a 0.2% countywide sales tax to benefit Gage Park, the Topeka Zoo and Kansas Children's Discovery Center?" GPIA meetings are open to the public.
