ENGINEERING REVIEW
COMMENTS No. 3
1. The Stormwater Pollution Prevention Plan does not meet all State requirements.
Please rename sheet to Erosion Control Plan.
2. Sheet SD2- plan view shows 2-18" PVC pipes crossing Pavilion Drive; Profile
shows ADS pipe.
3. Regarding the 138" Sq x 186"junction box— Please consider a cone for the top 6
or so feet of the junctions box. We believe this would be less expensive and
more structurally sound.

ENGINEERING REVIEW
COMMENTS No. 3
1. Utility Plan Layout, Site and Grading Plan, and Sheet SS2 are missing from the
set of documents turned in for review.
2. Provide detail for tie-in with SH6 pavement.
3. The backfill requirement for ADS pipe is cement stabilized sand regardless if it is
located under pavement or not. I do not see that noted anywhere.
4. Please provide ramps to Cross Pavilion Drive where sidewalks end at TxDOT
ROW.
5. Some of your General Notes conflict with City standards. We require 6" lifts, not
12" and 98% standard under pavement, not 95% modified. In addition, structural
backfill is required to extend 5 feet on either side of pavement edge.
6. Class IV RCP is shown on the street profile and ADS on the storm sewer profile
for the same pipe, Sheet SD2. Please rectify.
7. Is the ADS pipe water tight?
8. Do you know if the existing 4' box culvert at Sebesta Road is 789 or 850? If it is
789, it requires 2 feet of cover, so you may need to replace it with 850.
9. You need to use City of College Station details for sidewalks.
10. Shouldn't the proposed 6" water line crossing at Station 1+20 be existing? (SD3)
11. Where are the profiles for the storm sewer crossings on Corsair Circle?
12. There appears to be a conflict with the private sewer service and the storm
sewer at Station 5+60. Should there not be some cushion? (SD6)
13. Show conflict with water line Station 0+16. (SD7)
14. Provide details for your junction boxes providing outer dimensions and
separation for the multiple pipes.
15. It appears that you may need dissipater blocks on the outlet of the detention
pond.
16. Provide existing grade of Sebesta on profile from Station 0+00 to 0+58. (SS1)
17. Manhole required at Station 25+50 instead of cleanout. (SS5)
18. Waterline requires 4' minimum cover, Sta 3+92. (SS6)
19. Cement stabilized backfill is also required on ductile iron pipe with covers less
than 3.5 feet.
20. Manhole required at Station 25+50 instead of cleanout. (SS7)
21. Utilities are required to be buried 5.5 feet inside the easement edge. You are
showing 5 feet.
22. You call out Note #10 on Sheet W1, but do not reference a sheet.
23. A 14" Steel encasement pipe is required for a 6" line. You are showing a 12" at
Station 1+90. (W5)
24. It appears that a 45° bend is required to connect to existing AC line at Station
3+39. (W5)

ENGINEERING REVIEW
COMMENTS No. 2
1. Submit storm sewer calculations and revised Drainage Report. The storm sewer
cannot be reviewed any further without this information.
2. You will need to use City of College Station standard junction box. (SD7)
3. What type of curbing are you proposing in TxDOT ROW? TxDOT does not allow
6" curb.
4. Please designate Storm Sewer D and E as private, as well as the 36" HDPE line
through Lot 10 to the detention pond.
5. Is ASTM 76 RC pipe traffic load? I think you need a Class IV pipe for direct load.
Class III pipe requires 1 foot of cover.
6. Verify that you have enough cover on HDPE pipe crossing the roadway.
7. Why are you discharging into the top of the detention pond? You may get more
fall if you lower the outlet.
8. Trickle channel required from outlet into detention pond to outfall.
9. The flow line of Section C2, Storm Sewer B is higher than the flow in. This is not
acceptable.
10. Water and sewer crossings also require the joints of water and sewer pipe to be

at 5% deflection, and the sewer pipe shall be embedded in cement stabilized
sand for total length of one pipe segment plus 12" beyond joint on each end.
11. There are valves shown on plan view that are not called out on plan view or
profile. (W1 and W2)

13. Add gate valve to Water Line B. (W3)
14. FYI: The bore method for waterline does not need to be dry, it can be wet. Dry
bores are required for sewer lines.

1. Pursuant to your revised final plat submittal on 5-2-2005, no revised construction
documents were submitted which many of the first round of comments addressed. The
// following comments apply to the revised final plat submitted.
/2. Per our telephone conversation last Friday regarding the blanket easement, a scanned copy
of the original final plat was forwarded to Randy Trimble (BTU).
/3. Consider revised street name for Coreusier Circle that is easier to pronounce. The Planning
& Zoning Commission commented last week that this could be problematic for emergency
services and 911 dispatch functions.
Remove "Temporary Cul-de-sac" wording from plat.
5. Amend "Certificate of Ownership and Dedication", "Approval ofii1 e Cit Engineer",
