Accessibility Garden beds have been set at different heights. Most are relatively low beds at only nine inches above ground level, but one bed is set at eighteen inches and another is set at thirty inches. The garden is surfaced with three materials, all approved by the Americans with Disabilities Act (ADA) as acceptable surfaces for persons with mobility problems. The three surfaces are concrete, limestone sediment (also called limestone fines), and decomposed granite. The latter two allow for modifications to drainage and irrigation systems that run beneath the soil surface. The walkways and benches in the garden are both designed for use by able-bodied persons as well as those with physical disabilities. Pathways throughout the garden are at least 5 feet wide and benches are spaced as so to let a wheelchair be placed next to a person sitting on the bench. The grade throughout the garden is far more level than acceptable regulations would state. Adaptive garden tools are available. These include tools with short handles and large foam grips. Pruning tools with ratchet joints enable persons with less strength to prune large plant material. Tool carriers, stools, and other gardening accessories offer greater facilitation of many strenuous garden acitivities.
