It looks like a young southern alligator lizard to me. There are also northern alligator lizards in your area, however. To tell which it is, flip it over. If the lines traveling the length of the lizard's bell go through the center of the scales, you have a southern. If the lines go through the sides of the scales, you have a northern.
If you plan on keeping this lizard long term, this is what you'll need.
A 10-20 gallon tank (the bigger the better).
A substrate, I've kept alligator lizards on a variety of substrates, but I recently switched mine over to repti-bark and am quite happy with it.
A place to hide. You can either buy a cave of find something like a slab of bark. Both will work equally well. If you use a rock, make sure that there is now way the lizard could re-arrange the substrate and have the rock crush him.
A small water bowl.
A calcium supplement. I highly recommend rep-cal with vitamin D3. If you deecide to go with another brand, read the lable and make sure it does not contain phospherus, calcium phosphate, etc. Supplements containing phospherus are formulated for herbivorous reptiles. Feeder insects (crickets are the best for als) have plenty of phospherus, but very little calcium. Lizards need a 2:1 ratio of calcium to phospherus, in order to properly metabolize calcium so if your supplement contains phospherus, it's very hard to get the ratio right. If you don't supplement with the appropriate calcium supplement, the lizard will start using the calcium in it's bones. This will lead Metabolic Bone Disease (MBD). Lizards with MBD will lose the ability to eat when their jaws become too weak to crush their prey, suffer skeletal deformities, be prone to fractures, and eventually die.
Crickets are the best food for your al, prior to feeding, allow the crickets to eat something nutritious like crushed high quality dog or cat food, or fish flakes with fresh fruits and veggies (oranges and carrots work well) for moisture. Half the nutrition your lizard gets will come from the stomach contents of it's prey so it is important to gut load prey items. When you're ready to feed put them in a bag with some of the calcium powder and shake so that the powder coats the crickets.
Special lighting and heating are not necessary, but a UV light can't hurt.
