Address a letter to your local official identifying the park by name (a park in Fresno, CA), the improvements you think should be made, and why you think it is worth the resources of your local government compared to other projects they might be considering.
As far as who to write your letter to, look up your park to learn if it is a county or a city park (or maybe a state or federal park). If it’s a county park, choose a county official, like someone from the Board of Supervisors. If It’s city park, one of the City Council members would be a good choice, or a park employee. If it’s a state park, you need a state official, etc.
