(Portland, OR) -- The City of Portland is launching a pilot program to plant trees in under-utilized parking spaces. The first phase of the Trees in the Curb Zone pilot will focus on Southeast Duke Street between 82nd Avenue and 94th. Fifteen trees will be planted in place of a parking space. A curb is built around the tree and vehicles car park on either side of the area. In addition to creating space for the new trees, the City will also fund a limited quantity of yard trees for properties along the street.
