[ColdNoMore]

Small claims court to make her pay for the cost of re-sodding...your now ruined lawn?

With all of the contacts you've made and documented, plus a copy of the excessive water usage by her (go back a bunch of months if possible, to get an idea of when it started)...you may have a good/easy case.

While you wouldn't want to re-sod before she gets it repaired of course...get three estimates to bring with you to the judge.

If nothing else, maybe dragging her insolent butt into court...might finally get her attention?

If you don't want to go that route, is there a location on your shared property line, where you could set up your own hose to run full blast on your property (make sure to keep the hose outlet on your own property), but that all of it would drain onto her property (think short piece of gutter to act as a trough)...without damaging your lawn too much more?

Fight 'flood with flood'...I always say.

Good luck.
