SH 121 Water Line (Coppell Road to Denton Tap Road)
WA 01-01
Final Review Comments
Dear Mr. Showers:
The city has acquired all of the right-of-way necessary to construct the above referenced project and is
ready to final the plans and specifications and proceed with the bidding phase. Following a review of the
plans and specifications, the following comments are offered for your consideration:
PLANS:
General Comments
1. Verify the wording on the engineer's seal should it read 'registered or licensed?
2. Valve spacing - should more valves be added to the water line?
3. If fire hydrants are installed instead of air release valves, the Utilities Department will be required
to send a crew out weekly to bleed off all of the fire hydrants. Can the fire hydrants be eliminated
and air release valves installed?
4. If the fire hydrants are eliminated in locations where air release valves are required, will fire
hydrants need to be installed in other locations?
5. Use both concrete blocking and restraint glands at all bends, fittings, etc.
Cover Sheet
1. CITY COUNCIL - The City Council list needs to be updated as shown on the attached list.
2. Change the date on the plans.
Sheet No. 1
1. NOTE 2 & NOTE 22 - state the same information. Note 22 can be deleted. The city does not
have an erosion and sedimentation control manual - they have standard construction details and
ordinances.
2. NOTE 26 & NOTE 27 Is there a conflict between the two notes? Why is there not a pay item
for the metal post and cable fence?

Sheet No. 2

within the right-of-way and on the Staton property. Is this concrete to be replaced?
