Annual Stakeholder Roundtable Proceedings

Each year the CDPH Environmental Health Investigations Branch's Site Assessment Section (SAS) convenes a day-long Stakeholder Roundtable. The Roundtable involves community residents as well as representatives of non-governmental organizations, academia, and federal, state and local agencies. It offers an opportunity for participants to share experiences, and it gives SAS staff an opportunity to hear directly from residents about environmental health problems in their community. The Roundtable fosters a productive learning environment for participants and helps guide SAS's work.

Listening to South Gate: The Community’s Environmental Health Concerns

To evaluate environmental health problems in the city of South Gate, in Southeast Los Angeles, the California Department of Public Health (CDPH) applied the Protocol for Assessing Community Excellence in Environmental Health (PACE-EH), which was developed by the Centers for Disease Control and Prevention (CDC) and the National Association of County and City Health Officials.

PACE-EH is intended to help engage and empower residents in identifying, prioritizing and addressing environmental health problems in their neighborhoods. To implement the PACE-EH strategy, CDPH gathered information using the Community Assessment for Public Health Emergency Response (CASPER) framework. The findings of this work are reported here.
