From: Jesse L. Craft Geologist Date: 8/30/95 Subject: Tatum Complaint Investigation To: Mike Rosenthal Denver Item 3, page 7 of my report on the Tatum Subsidence investigation should be considered a typographical error. As you know the original copy of the photograph was not too clear and we discussed this problem over the phone. The second print you sent clearly showed the poles in place so I removed the statement about the poles in the first part of the report forgetting that I had used it again in the summary. I was on travel when the report was finalized and the second use of the statement was not corrected. The statement about the rafter poles stands. In southwest Texas along the Mexican border where I use to live the poles sticking out of the walls of the adobe structures were rafter poles. If they are just decorative on this structure OK but my experience is that they are not decorative. About the gutter drain. If one looks closely at the photograph you can see where the drain pipe turns the corner around the side wall. One assumes that.this pipe is connected to a drain to carry the water away from the lower roof. If not it is cascading the water onto the lower roof. No I cannot see the pipe but it is logical that the pipe is there. Comment on the measured subsidence. The SDPS Profile Function program shows that with 75$ extraction there is a predicted subsidence of 4.22 feet in the center of the panel. Even with this much subsidence in the center of the panel there is no subsidence anywhere close to the Tatum house. How could .25 inches or even .5 inches measured in the approximate center of the panel have any effect on the structure. The reason I used the 1988 to 1993 subsidence data was that one of the stations was destroyed in the later data and gave a misleading reading of subsidence.
