(dated 7/10/2006)
Castlegate, Section 7, Phase 1 — Final Plat
Planning:
1. The metes &bounds description has been checked and now closes. (The problem
was at the intersection of line tags L3 & L4).
2. The plat has been tied to a control monument.
3. Right-of-way and pavement width info has been provided for Victoria Avenue.
In addition, a 5' Right-of-Way Dedication has been added along Victoria Avenue.
'4. Information for Abercorn Lane has been added.
5. Noted.
Engineering:
1. PDE's have been modified to be over the storm pipe only. (Easements adjusted
are located in Common Area No. 2 and between Lots 3 & 4 of Block 1). In
Common Area No. 2, the PDE is now its own easement within the PUE of the
common area.
2. The PDE between Lots 3 & 4 of Block 1 (for Storm Pipe 7) has been extended to
include the outfall of the pipe.
3. Yes, the blanket easement includes this property and it is still in effect.
4. Noted.

1. As you know the minimum sewer grades are based on minimum velocities flowing
full. Several of subject lines are depicted with there estimated ultimate flows as they
will not be extended; however, the associated velocities do not achieve the local or
state minimum flushing velocities of 2.5 fps or 2.0 fps, respectively. Grades on this
project appear adequate to achieve more desirable velocities. Please revise
accordingly.

1. Your drainage report certifies that there will not be any impact on properties
downstream of the Crowley Tract resulting from this development. Are you also
certifying that there is no impact downstream of Section 7?
2. Is the runoff coefficient of 0.5 adequate? The previous report for Section 7 used
0.5, but the development was for a less dense residential development.
3. Page 3 of the Drainage Report states that the runoff flows into a proposed
regional detention facility. I'm assuming you mean the existing one.
4. Please show in the plans the grading required to keep the 100-year storm within
the ROW.
5. What is the size of the existing storm pipe into which Pipe 1 is discharging? Is
there capacity?
6. The drainage from off-site onto Stone Castle Circle and from Stone Castle Circle
off-site needs to ensure that there is no undermining of the roadway. Please
address.
7. The manhole lids in the pavement near the storm inlets shall be water tight.
8. Are you able to center a joint of pipe (min 18') over the sewer line at Sta 0+15,
Sheet 6? How are you planning to meet TCEQ requirements at this location?
9. Plan view calls out 8X6 tee at Sta 3+20.35. Profile shows 8x8. (Sheet 6)
10. The sewer (and future water) line crossings under the high pressure gas line may
need additional protection (encasement). Please provide documentation from
Citgo with their requirements for these crossings. (Sheets 9 and 11)
11. Show conflicts with gas line crossings.
12. Submit water and sewer design reports.
