Almost everything that landscape architects design is ultimately for a “community.” Community can be the boon or bane of a project, and oftentimes both. This issue of LA+ aims to explore how, over time, each of us moves in and out of multiple communities, shaping them as they shape us and in turn shaping our landscapes and cities. We ask how different disciplines construct different ideas of community and how those communities are anchored in space and time, whose interests they serve, and what traces they leave. And we examine how—in this pluralistic, fragmented, and fluid world—designers can meaningfully engage with communities.
