The problem I'm having two fold. The yard is not level at all. I'm going to level it with builder sand as opposed to river sand. Any comments on that are welcome.

The other problem is that the sidewalk, curb, and driveway are all 1-2 inches above the top of the grass. Sometimes higher in some areas.

How can I fix this? Just lay down a quarter inch to and inch of sand each year? Just repeat that process until it gets to the height I want?

I can't even edge properly in some places since the grass doesn't reach the top of the curb.

Dirt or sand? Sand is great for leveling right? What about for increasing the height like I'm trying to do?

I would suggest renting a sod cutter and bringing in dirt, then cutting out the sod and placing it off to the side. Then spread and level the dirt in the areas where it is needed to bring the soil level up to where you want it to be. Then water heavily to settle the dirt, let it dry out, then add more dirt to areas that have settled, and then tamp down all the areas where dirt has been added. Water the areas again, and then replace the sod (you'll want to put the sod down on a moist, but not muddy, soil bed). Water sod 2-3 times daily for about 2 weeks until you can't pull up the sod off the ground (this is when you know that rooting is taking place).

The sod has been down at least since April. So I'm not sure if lifting it up is as simple as it sounds.

texasredhead seems to be pretty sure that the winter weather is not an issue. He would know better than me since I don't live in that neck of the woods. Good luck.

Second (and I admit that I like the easy, lazy, and cheap way), I'd forget the sod cutter. Right now, I'd add as much top soil as I could without smothering the grass. Early next spring, I'd do it again. There's a good chance that will be enough but, if not, I'd do it a third time without worry about smothering anything. Bermuda spreads rapidly and will fill in quickly. It's Bermuda so anything short of RoundUp is not going to kill it.

I completely understand that your method works (I've used the same topdressing method many times with soil and sand), it just takes about 1 year to get the desired result.

It just depends on how much effort and patience the OP is willing to put into the project.

If this were earlier in the year, I might dig up a shovel sized area of sod here and there. Then level everything as you described above, then break up the sod and drop on top. Granted, I'm looking at ground under repair for a few weeks while you're looking at a finished project. I don't see it taking a full year, though.

Lots of ways to get it done.
