This week I finally found an experimental location near Southwest High School. This location I thought would be a good start becasue the area is kind of poor.
Then I made an actual layout in sketch up placing the playground, garden area, parking lot and picnic area. I have all the dimensions taken and trying out different textures. The garden area is similar to a pit with large steps leading into it that could act as a seating area as well.
Now all I have to do is add the actual playground and quality people look for in a park. Also include landscaping such as vegetation (trees, plants, and grass) and outdoor furnitute (benches, tables, light fictures, etc.).
