I wouldn't stress over it. Employers look for someone in an umbrella of majors, because every school is going to have its own names and standards for their class templates. If I saw someone list community development as a major, I would think it would overlap a great deal with urban development, with maybe a bit more focus into civil engineering or sustainability. You'll want to explain how your background is relevant to a position in the interview anyway. I wouldn't expect it to get you eliminated before then.

Also, it's a cool opportunity to stand out with how it differs from a more traditional major. People like hearing how you chose to include something that you felt was lacking from the default path because you thought it was important. Choosing to specialize demonstrates thoughtfulness, passion, and mastery. You'll be fine.
