Community health planning is that activity within urban planning in which planners work with architects, public health professionals, and others to create a healthier, safer, more connected city. Concepts that are central to planning – design, resource environments, land use, mobility, environmental hazards and sustainability – are also central to community health planning. While planners have long engaged with these issues, they have become more prominent over the last forty years, and are now viewed as a critical element of planning practice, especially for those interested in social justice. Concerns about tobacco and lead, then obesity, have reinforced theoretical concepts about the role of environment in sustaining individual and collective health.
