Lilacs come to mind right off the bat since I have a hedge of them in full sun and they get plenty of road salts each winter season. There are smaller varieties than the common lilac - my hedge is 108 years old and has topped out at perhaps 15 feet.

Here's a short salt tolerant list without regard to eventual sizes, etc.
Green Ash: Fraxinus americana
Shademaster Locust: Gelditsia triacanthos
Larch: Larix species
Colorado Spruce: Picea pungens
Austrian Pine: Pinus nigra
Ornamental Pears: Pyrus species
Large Toothed Aspen: Populus grandidentata
Red Oak: Quercus rubra

Junipers: Juniperus species
Honeysuckle: Lonicera species
Bridlewreath Spirea: Spiraea x Vanhouttei
Snowberry: Symphoricarpus species
Lilacs: Syringa species

I was also looking for salt tolerant plants, but ground covers just for a small patch that will be about 2ft by 8ft that borders the street and the driveway. It is on the East side of a Maple and would only get a short amount of sun in the morning.

Any ideas?

Salt that injures plants is that soaks into the soil and then absorbed not the salt the residue accumulated on the leaves and stems.

I live on an island only 100 yards from the Atlantic ocean. The soil is almost all sand. Yuccas do great out here. They grow fast and seem to love the salt everywhere.
