I need your help to complete my Eagle Scout Project!

The project I have chosen for my Eagle Scout Project is to help Eastern Shore Chapel create a memorial garden. Eastern Shore Chapel has a number of memorial benches that are scattered around their property. They would like one dedicated area on their campus to place all of the memorial benches. My plan it is clean up a natural area by trimming back the overgrowth, and planting additional shrubs. I also want to clean up the benches as some have lichen growth on them.
