Costa Mesa 311 is the simple door for city service requests
Costa Mesa 311 lets residents submit, track, and view city service requests online or by app, including graffiti removal, pothole repairs, and other city service needs.
Costa Mesa 311 is the simple place to start many city service requests. It works through the city’s website and a free phone app. You can send a request without first guessing which office handles it.
Use it for regular city service items such as graffiti removal and pothole repairs. The request system lets residents submit, track, and view requests. From a phone, it can also use the location of the problem and a photo, which helps city staff find the exact spot.
That helps in Costa Mesa because the city mixes homes, shops, the fairgrounds, busy streets, and small business areas in a compact space. A clear location keeps a request from becoming a scavenger hunt.
For the cleanest report, include the address or closest cross street. Add a short note and a photo when the issue can be seen. If the item is really a police matter, permit question, water provider issue, or county or state problem, use the more exact contact instead.
