Re: 35,000+ Gallons / Day is washing away the soil under my basement
***! You're right, that's way too much water for it not to be a problem.
My first question is if any of your neighbors are having water problems or if you're the only one. It would seem odd that neighbors aren't having similar issues. It also wasn't clear by the Google Earth shot where your house is located in relation to the rest of the development OR in relation to the additional homes recently added to the development. If the problem didn't start until after the new construction started, it's possible that a natural aquifer has been diverted by road construction or other infrastructure installation.
There's got to be a city/county/state environmental, water, or geology department that would take an interest.
Sorry that I can't be of more help.
