If you don't want to state the time setting at the beginning of the story, you can choose seomething which happened about 2015 and have a character mention it as something which happened about 20 years earlier. And maybe another character mentions something which happpened in 2010 as being over 20 years earlier. And maybe someone mentions that Y2K or 911 was about thirty or forty years ago.

But if you do want to state the time setting at the beginning fo the story, but not specify the exact yearI don't have much advice.

"Los Angeles 203__" seems the most natural to me.

Or maybe "Los Angles, the Twenty Thirties".

Or maybe "Los Angeles 20 minutes into the future".

TV Tropes - warning, a great time waster - has a trope called "20 Minutes into the future".

The Future, but not so far into it that you'd notice except for the abundance of Applied Phlebotinum.

Both Max Headroom and Brazil lampshade the Zeerust problem by setting themselves explicitly "20 Minutes into the Future" and "Somewhere in the Twentieth Century", respectively (rather than identifying specific dates), and by mixing up production designs and costumes that would have been considered "futuristic" in the '80s with random elements from previous decades.
