Is this area in full sun or under the canopy of street trees? Unfortunately, there are fewer native groundcovers 12" or less for full sun than part shade.
I am assuming that this is what is known as the hellstrip and will be subject to lack of water, occasional street & sidewalk salt in the winter and possibly snow piled on it by a snowplow. Please let me know about the sun and I will pull together a list for you.
First, do a soil test and figure out what you have on this strip.
Then before planting anything, amend the soil with lots of organic matter to break up your clay and make it better draining. I say this because if snow from the street sits on these plants in the winter and the soil is not well draining, almost all plants will get root rot.
Read this book, you can borrow it from the Delaware library system. The strips she designs are bigger than most of my gardens, but the information on maintaining a 'Hellstrip' is invaluable.

I have attached a list of plants that fit the criteria. Most are natives, some are not; but all are excellent plants to help fill in a planting of this kind. Some might push the edge of the 12" height with flowers that can be cut off after blooming; then the plants are well within the height restriction.
I have HOA restrictions where I live so I could only landscape my mailbox area. A photo is attached. I have used Nepeta" Walker's Low', (covered today in bees), Yarrow 'Paprika', Sedum 'Aureum', and an Annual Dusty Miller which tends to return every year here. I seldom water and it has filled in so weeding is minimal, I spend more time deadheading to prevent flop and keep it tidy and reblooming. Sorry I don't have a winter photo. I cut the yarrow and nepeta back and it stayed green all this past winter; the sedum stayed yellow and just needed tidying up in the spring. I now have some Salvia lyrata coming up, that I cut off the flowers of after blooming, and the reddish leaves look nice amongst the sedum.
Good luck with this project, send a photo when you are done.
