“There is a decent fault line map at this url.
Much more than this and you would need to contact the GIS department at Harris County Flood Control (I think). The Long Point fault is interesting. More interesting to me was the Pecore fault in the Heights. I bought a home with no disclosure from the prior owner or the inspector. All the neighbors knew but I did not know them. Went to sell it after remodeling the property and it comes up. Obvious when I drive that area now. Ultimately it was a disclosure item but not an issue at sale.” [sboney, commenting on Yards of Yard in Britmore Oaks]
