So. I have what I'm sure is not a unique problem, but sure is an interesting one.

The people who built my house built the foundation wrong. Instead of digging a hole, then digging a deeper trench for a foundation, which insures the foundation is on compacted soil, they made a mold around the edge of the hole. Then put some sand on top.

As you can imagine, 60 years of settling has resulted in my foundation kind of sitting on tiny plateaus of compressed sand, and those plateaus are slowly eroding away. Especially in this one spot where there was water seeping in because they also did the grade wrong.

So anyhow, my understanding is that the best solution is to add a bunch of fill dirt into the 5ft "luxury crawlspace," compressor, and repeat until the dirt is at least level with the foundation footer. To the tune of approximately 60 cubic yards.

As you can imagine, this is an awful lot of dirt. And the only entrance to my crawlspace is a 10sqft hole at the back of the house, far from where dirt could be delivered.

How the hell am I supposed to do this? I feel like the most cost-effective way would be to have the exterior wall and floor of one bedroom ripped off so that the dirt can be pushed/poured directly in, and then an army of assistants spreads out the mess.

I'm sure I could ask a contractor (and will given scope of work), but I'm trying to get a rough feel for the work required so I know if I'm being completely ripped off.

My backyard has become a muddy mess and it's creating some downstream effects, such as me spending WAY too much time vacuuming and mopping (3 dogs), and not being able to do anything meaningful in the backyard. Here are some details:

• I'm right on the edge of USDA zones 9a and 9b -- the map shows that my house is specifically in 9a, but one block south of me is 9b
• The grass in the backyard was mostly St. Augustine when I bought the house. For a number of reasons (some really harsh winters and summers, three dogs trampling the grass, etc.), the St. Augustine is entirely gone
• Last fall, as a stop-gap, I put down some weed killer to control the weeds and seeded the entire backyard with winter rye. It grew amazingly well and I had a lush, verdant backyard for one season.
• This spring, my plan was to grow bermuda grass. My thinking was that it would be able to withstand the summers but could also handle the dog traffic a bit better. So, I did some pre-emergent, scalped the winter rye, raked up most of the detritus, got the ground really wet and muddy, and laid down some bermuda seed + fertilizer
• Now, almost a month later, I haven't seen a single bit of growth. The pre-emergent has done a pretty good job of keeping the weeds out and some winter rye is still growing here and there, but other than that, it's just... mud.

So, what are my options, especially this late in the season? Should I just throw in the towel and sod it with St. Augustine again? Did I do something wrong with the bermuda? Do I need to make it through a muddy summer and reconsider my options going into the fall?
