There is an election for County Commissioner coming up later this year. There are a couple reasons I'd rather not even try for the office: it's an "Old Boy" network out here, and I
really don't want to be a politician! shudder!
I've been reading up on filing a Writ of Mandamus at
http://www.ehow.com/how_5114293_file-petition-writ-mandate.html I've also been reading (too much) of the TX Water Code, and re-reading their response to my last letter. In my letter I'd mentioned "rainwater runoff", in their response they stated that "rainwater runoff" isn't considered "waters of the state". Section 11.021 of the Code states that "The water of the ordinary flow,.........and rainwater of every river, natural stream, canyon, ravine, depression, and watershed in the state is the property of the state." Seems to me that means "rainwater runoff" would in fact be considered "waters of the state".
I've drafted another letter to TCEQ quoting the above definition and requesting they at least send a representative out to review the situation. Who knows, a "visit" from one of their rep's just might be enough to get the neighbor off his duff.
In the meantime, I'll still be working on some of the other suggestions; title insurance, lawyers, filings, etc.
