Okay kiddo, so do you know how some parts of your town can be very different from other parts? Like how there might be a downtown area with lots of stores and a park, but then other parts of town might have fewer stores and more houses?
Well, sometimes people want to help make the less busy parts of town better and more like the busy parts. So they create something called a regional development commission. This is basically a group of people who work together to figure out ways to make different parts of a region (which is just a fancy word for an area that includes lots of towns and cities) better.
The people in these commissions might talk to community leaders, government officials, business owners, and regular people who live in the area to figure out what changes might help. They might ask questions like, "do we need more parks, or more stores?" or "how can we make it easier for people to get to work or school?"
Once they figure out some good ideas, they might try to get money from the state or federal government to help pay for these changes. Then they can start making things better in the area.
The goal of these commissions is to create a better place for everyone to live and work. They want to make sure that every part of the region has opportunities and resources for people to succeed.
