I recently purchased a house on a 0.25 acre (0.1 hectare, ~11,000 sqft) lot that in the past was known as "the party house." This name became more clear to me today while raking leaves I found large quantities of broken shards of glass throughout the lawn, presents no doubt left behind by previous tenants and their guests.
My goal is to make make my yard free of glass, such that my family and guests can walk around barefoot without fearing cutting our soles to shreds.
Picking the glass up is not realistic given the size of the yard, the amount of glass (everywhere), and that I know I will miss many pieces. Brown, green, and clear glass blend expertly into the moist, lush lawns found in the Pacific Northwest.
I was thinking of dumping clean fill and reseeding or alternatively placing down sod. My concern would be raising the grade or not adding enough material to cover the glass. Digging out the top few inches of topsoil could counter this, though I expect this would be starting to get pricey.
I am wondering if my approach is the best approach or if there are perhaps other methods I can try that I haven't yet considered?
