Dear Floyd:
On Wednesday, October 9, 1991, you provided me with a trench safety
plan, prepared by Louis L. Hargis, P.E., President of Geotechnique,
Inc., a Professional Engineer in the State of Texas. This plan was
designed specifically for the use in the construction of the water,
sanitary sewer, and drainage improvements within the referenced
addition.
Although I am not an expert in the field of geotechnical engineering,
or the preparation of a trench safety plan, I do have some concern
about the trench safety plan provided. It appears that this plan
calls for all trenches to be "sloped back" on a minimum calculated
grade. The concern I have is that there is no room along the West
property line in the vicinity of line "S-I.I", between the existing
sanitary sewer line and the first upstream manhole of line "S-I.i" to
"slope" an open trench. As you can see on the sanitary sewer plan,
this line is located in a proposed ten foot wide concrete alley which
-is situated five feet away from an existing fence line. This existing
fence line is not within our property and would be subjected to
removal if an open trench system is used during the construction of
this sanitary sewer system. Please have your Geotechnical Engineer
investigate this problem before you begin constructioh of these
improvements or contact each of the homeowners in this area to find
out if you can remove these fences and cut a ditch w~thin their
property. Based on our dealings with the existing homeowners
association, I doubt very seriously that they will allow you onto
their property.
. Again let me ~emind you that it is very important that you follow the
. trench safety plan, especially during this "rainy" part of the year.
"If this plan needs to be revised, please do so before beginning
construction.
Sincerely,
Kevin R. Kendrick, P.E.
