Thanks to Roman Mars and Ted Kaye, Good Flag, Bad Flag, and 2015 having become basically the Year of the Flag, there are efforts underway in lots of US cities to improve their municipal flag designs. Here are the cases we know about: Albuquerque, NM; Austin, TX; Billings, MT; Birmingham, AL; Bloomington, IN; Boston, MA; Bowling Green, KY; Columbia, MO; Dallas, TX; El Paso, TX; Grand Rapids, MI; Los Angeles, CA; Lowell, MA; Minneapolis, MN; Oklahoma City, OK; Pocatello, ID; Provo, UT; Raleigh, NC; Rochester, MN; Salem, OR; San Francisco, CA; South Bend, IN; Syracuse, NY. And, just over the border, Victoria, British Columbia. For Provo and South Bend, efforts have paid off as new flags have been adopted.
The following are the current flags for each city. Click the city name in the caption to learn more about the redesign effort.
In addition, there are efforts underway to create flags for the flagless cities of Fargo, North Dakota and Manlius, New York, following the lead of Bath, Maine; Sioux Falls, South Dakota; and Sunnyvale, Texas, all of which recently adopted flags for the first time.

Thank you for sharing. Sunnyvale, TX should be a simple fix. Tweak a bit. See what comes up? Albuquerque: remove name and year. Austin and Billings need re-do’s. Major re-designs are needed for Boston, Lowell, San Francisco and South Bend. Salem, remove name and you have a perfect flag for Oregon’s capital. Best among the group that need no change at all is Bath, Maine.
You can now add Oklahoma City to the mix: okcflag.org. I’m a one-man committee right now, but I’ve got high hopes.
