Measure the available space and draw a plan that shows the space in relation to the school buildings, particularly the entrances to buildings, roads and pathways.
Check federal, state, local and school district regulations relating to school grounds. For example, Illinois requirements include "building permits/certificates of occupancy, annual inspections by the regional superintendent, annual fire safety inspections by qualified fire officials, and decennial inspections by licensed architects or engineers." Your grounds must also comply with accessibility standards, allowing students, teachers and visitors with disabilities to enjoy the spaces fully.
Compile a list of priorities for use of the space. Your design will be driven by the age of the students utilizing the grounds, and balance a mix of playground, sports fields and pitches, covered study areas, gardens and environmental grounds for biology and geography fieldwork and parking lots.
Solicit donors and sponsors for the new grounds design. Local garden centers and home improvement stores may be able to supply valuable resources and advice at low or no cost. You could also ask local architects and landscape designers to get involved in this community project and ask former students and teachers to donate plants, trees or furniture.
Draw up scale plans and get quotes for completion for the project. Your local school district and municipality may be able to provide the construction services at the most affordable rate.
