Disposing of Demolition Materials (sand and concrete) Costs?

[Kristine Groemping]

We had our first contractor nightmare.  I guess that makes us official real estate investors.  We just discovered he dumped demolition material including sand and concrete in our backyard.  Instead of buying dirt this is what he used to fill in the egress window hole and then proceeded to spread it across the whole backyard.  It's as deep as 8 inches in some spots and maybe only about an inch deep on the right side of the property. Now we have to pay to get it removed and the backyard resoiled.  There is a lot! Maybe 2 dump trucks worth of material.  I'm curious if anyone has experience with having to dispose of construction material and the costs.  I got an estimate for $1950 to properly dispose of this material in the DC/MD area.

Our solution to fix this problem is: 

1. Remove the material- obviously we can't grow anything in this and it's a water drainage issue with the basement. We have had water issues in the basement in the past.  We just finished gutting the whole thing and would love to not have to do it again. $1950

2. The yard is on a pretty steep slope so bringing the soil from the back of the yard to the front and adding topsoil to the rest (basically grading the yard). $1450

3. While we are digging, installing a drainage system. $775

4. Grass seed + compost material to promote growth (2 inches). $450 + $400 = $850

This is our first major project so I would be ever so grateful for any feedback from this awesome community. :)
