The acreage behind my rural lot is slated for a housing development. Right behind my back property line is the beginning of a creek that runs parallel to my back property line and deepens to 8 ft before it passes my corner survey rod. The only way I can see the developer building on that (small) lot is to fill in that low area. Seems there would be some type of restriction as I'm afraid it would allow water drainage to then flow onto my property. What agency or county department should I contact for information/ guidance? I'm thinking the county engineer, but Texags knows stuff. Thx!
