C 1) C5.5/5.6 - Please provide the minimum 4 -ft of cover. (FYI...This measurement should be
taken from finished grade straight down to the top of the pipe rather than perpendicular from
the pipe to the ground.) { 4o

C5.5/5.6 - Easements nee to be adjus a to assure thavthere is at least 5.5 -ft from the
3. edge of the pipe to the edge of the PUE. a
C5.5/5.6 - Verify that the minimum 9 -ft TCEQ horizontal separation distance between the
outside of the water and sewer pipes is being maintained. h
C5.5 - Where the water is crossing the sanitary sewer line, please note the TCEQ crossing
requirements (i.e. centering joint of water pipe, etc.)
. FYI...There are still public utility and access easements associated with this project which
will need to be dedicated by separate instrument or plat prior to issuance of the Letter of
6. Completion. I don't want this to negatively affect your timeline.
6 C5.6 - Based on the as- builts, it looks like you are proposing tying onto a 12 -inch stub from
/a 12x6 tee rather than a 6 -inch stub. Please verify and add a reducer if needed. -trot's t,u4Sn't
Please provide a revised cost estimate. �dd�SSed 7
8. Water Report - Please indicate where the specified friction factors came from.
9. Water Report - Scenario #1 - Where did the 1450.54 gpm at R094 coming from? This
scenario needs to include the average daily flows anticipated for the development.
10. Water Report - Scenario #3 - While the residual pressure obtained during the actual fire
flow test may be used to calibrate your water model, the model needs to show demands
totaling 2500 gpm from 2 fire hydrants so pressures and velocities can be verified.
