Planting Conditions

Although plazas tend to consist mostly of hardscape to facilitate pedestrian circulation, seating, and programming, plantings make them more inviting and can help define spaces within them. Plazas allow for larger plants and a greater diversity of species than is possible in more constrained areas such as raised medians or tree beds.

Review Pedestrian Plaza for more information on general plaza design.

In-Ground Planting Area

Planting areas within plazas that are level with the surrounding grade. The size and shape of the area may vary, and it is typically employed where there are few underground constraints.

Raised Planting Area

Any planting area within a plaza that is raised above grade. The size and shape of the area may vary from site to site and is typically employed where there are underground constraints. The majority of the soil volume is contained within the above-ground structure.

Container Plantings

Containers are a flexible planting solution that can be used in locations where in-ground planting is not feasible due to sub-surface utilities or paving. Proper soil volume, plant selection, and irrigation are key to maintaining healthy vegetation in planters. Consider containers, of a variety of sizes and shapes, that can support small trees and understory plantings including shrubs, grasses, perennials and bulbs.
