The James River holds an undeniable importance in the foundation and development of the City of Richmond. The Richmond Riverfront Viewshed Project, initiated in 2013, aims to find the balance between the conservation of scenic river views and appropriate development along the James River. A series of Geodesign techniques and methods have been applied to each stage of the project. First, the combination of community engagement and crowd-sourcing approaches created an inventory of river views. Second, 3D spatial analysis reveals favorite views in the city, as well as the important landscape elements in those views. Finally, a web-based design evaluation tool is developed for users to assess the visual impacts of newly proposed development projects. Such evidence-based, instant feedback to the design process highlights the value of Geodesign in landscape design and planning.
