COMMENT STATUS: ,/'PRELIMINARY FIN.~L ]
1. A note on the plans show that the sanitary sewer easement Volume 81052, pg. 3117, that
runs north and south, will be abandoned with the plat. However, the utility plans still
show a sewer line to remain in the southern portion of that sanitary sewer easement
across lot 5.
2. There is a proposed 15' utility easement between lots 5 and 6. The easement should be
a minimum of 20', also there needs to be some information provided as to what is
proposed within that utility easement, as the utility plans do not show a sewer, water or
storm drain in that easement. Is it your intention to abandon the existing 8" sanitary
sewer in its entirety and reinstall the 8" line between lots 5 and 6? If so, then your
preliminary water and sewer plans should show that.
Preliminary Utility Plans
1. Please explain how you intend to tap a 6" water line with an 8" water line.
2. It does not appear as though you have adequate separation between your water and
sewer at the southern ends of the development.
The 6" water line you are proposing to tie into is approximately a 25-year-old cast iron
water line. We have problems with the cast iron water lines in the Northlake
Woodlands developments. We have recently just replaced a substantial amount of that
water line along Meadowcreek Road. I would strongly recommend that you install an
8" water line on the east side of lot 6 all the way to Meadowcreek Road and connect to
the new 8" PVC water line on the south side of Meadowcreek Road. I am concerned
that tying into the 6" cast iron line that is 25 years old could be a source of problems
once these homes are developed.
When the final plans are submitted, there could be additional comments made on the
ontfall of the stormdrain to the south. Without knowing the actual outfall velocity, it is
difficult to ascertain whether the pipe should be extended all the way to the Meadowcreek
Road storm sewer system.
