In land-use planning, urban green space, or Downtown Greenspace is open-space areas reserved for parks and other “green spaces”, including plant life, water features, also referred to as blue spaces, and other kinds of natural environment. Most urban open spaces are green spaces, but occasionally include other kinds of open areas. The landscape of urban open spaces can range from playing fields to highly maintained environments to relatively natural landscapes.

Generally considered open to the public, downtown greenspaces, and urban green spaces are sometimes privately owned, such as higher education campuses, neighborhood/community parks/gardens, and institutional or corporate grounds. Areas outside city boundaries, such as state and national parks as well as open space in the countryside, are not considered urban open space. Streets, piazzas, plazas and urban squares are not always defined as urban open space in land use planning. Urban green spaces have wide reaching positive impacts on the health of individuals and communities near the green space.
