Downtown Spokane Partnership
The Downtown Spokane Partnership (DSP) is a private, non-profit membership organization that serves as Spokane's central city advocate and service provider dedicated to the creation of a dynamic, vital and sustainable Downtown as the basis of an economically healthy region.
The DSP has a great program to help downtown businesses replace and plant street trees and also a program to replace and install custom tree grates that do not injure trees as they grow.
