Creating tools for healthy development: case study of San Francisco's Eastern Neighborhoods Community Health Impact Assessment.

The San Francisco Department of Public Health recently completed a 2-year collaborative process, the Eastern Neighborhoods Community Health Impact Assessment (ENCHIA), to evaluate the potential positive and negative health impacts of land use development. ENCHIA resulted in a number of outcomes, including (1) a vision of a healthy San Francisco; (2) community health objectives to reflect the vision; (3) indicators and data to assess and measure the objectives and vision; (4) a menu of urban development strategies to advance the objectives; and (5) the Healthy Development Measurement Tool, an evidence-based tool to support accountable, comprehensive, evidence-based, and health-oriented planning. This case study describes the 18-month ENCHIA process, key outcomes, and lessons learned. The case study also provides an overview of the Healthy Development Measurement Tool and examples of its first applications to urban planning. Given the growing understanding of built environmental influences on health, ENCHIA illustrates the ability of a local public health agency to effectively engage in land use policy as a health promotion strategy.
