Grading my backyard
I must have read dozens and dozens of postings and their replies, but can't seem to find what would work for me. It seems all I've done is research for the past couple of weeks yet still don't know what direction to take.
We're in Michigan. We moved into a new house at the end of last summer. Our backyard is about 3,000 square feet (61 feet by 46 feet). Our entire yard is bumpy...twist your ankle type. It is also about 3" lower than our neighbors. We have some leaking in the basement on bad rainy days. And we have a few spots in our yard that are especially low, leaving pools of rain water for days after a rain (see attached image).
We're on a budget, and would like to do the work ourselves. Would any of these solutions work for us?
I have also attached a picture of the top 6 inches of our soil.
* Till the entire backyard, slope it properly
* Grade the yard with mason sand & fill in low spots with mason sand
* Grade the yard with screened top soil & fill in low spots with top soil
* Something else?
