Guys we at Emery Park RC did just what you all are doing last year. We went before the parks and Rec board and presented our proposal. We used Dirtburners in STL as a example because they are in a city park and have their stuff together. Be prepared to show cars and tell about what they are how you control them that sort of thing as most people have no clue as to how they operate. One of our board members made a slide show and did a outstanding job presenting it. We are a 501a non profit and made sure they were well aware of the fact anything we took in went directly back to the facility. PM me if I could help in any way.
