Raised Beds for Elderly Gardeners

Hello, my name is Samuel McAdams and I am part of Boy Scout Troop 107. For my final eagle project, I wanted to help an assisted living community near me to have raised garden beds. Many of the residents at this facility enjoy gardening, however, some have trouble bending down, digging the soil, and planting due to their physical disabilities. I want to make 2 raised garden beds as well as concrete paths so residents in wheelchairs or with canes would be able to enjoy gardening and stay safe while doing it. Any donation is greatly appreciated!
