Yeah, I got murdered on cost, but 15' ave with 0.6 acres. They hit really hard-packed clay and very large rocks so the estimated time went up. So $9500 for this. Quoted $6500 with no drain pipe, just overflow.

Really wish for a drain pipe now that I saw what it looks like with 1" of heavy rain in 20 minutes. 20' wide, 6" deep river on the outlet, with barely any grass yet. Had some washouts but not serious. Working on getting good grass started again this weekend.
