Where Costa Mesa Comes Together
About District 3
I may be biased, but I believe District 3 is one of the most dynamic parts of Costa Mesa! It’s where neighbors become friends, families grow up together, local businesses hum with activity, and community life unfolds in parks, schools, and everyday spaces.
Here, you’ll find longtime residents alongside newer neighbors; renters and homeowners; small apartment buildings and single-family homes; local shops and big gathering spots. It’s a district with heart, where people care deeply about the quality of life in their neighborhoods.
District 3 is at the heart of our city, bringing together neighborhoods, colleges, civic institutions, and major corridors that shape daily life in Costa Mesa. It spans much of eastern and central Costa Mesa, reaching from the city’s eastern edge toward its civic core. Its boundaries are defined by familiar streets, freeways, and natural features that many residents pass every day.
