Construction Plan Review Comments
Dear Mr. Burger:
The City of Coppell has reviewed the referenced plans and has the following comments
to offer:
Cover Sheet
1. Remove "L-I.01 Landscape Plan" from the Sheet Index. This department does not
review or approve the landscape plans.
2. The Engineer's signature and seal should appear on the Cover Sheet.
Replat Sheet 1 of 2
3. The 10'xl0' water easement described by T1-T4 should be increased to a minimum
of 25'x25'.
4. Provide a 25'x25' water or utility easement for the DDC as shown on the mark-ups.
Replat Sheet 2 of 2
5. Remove "Preliminary" verbiage from the replat.
Demolition Plan
6. The public fire hydrant that is existing on the site should not be removed. Relocate it
to the utility easement described in Comment 3 or to the existing ROW.
7. The plan proposes to remove a portion of the western drive approach. Why not
remove the entire approach as is proposed on the eastern drive approach for
continuity and a cleaner look?
8. Ensure ADA compliance of the existing ramps along Fitness Court. Remove and
replace the ramps if necessary.
9. The "Notes:" should be modified as described:
a) Note 3 should read "Do not interrupt existing utilities servicing facilities occupied or
in use." The architect is not attthorized to approve the interruption of public or private
ntilities.
b) Note 5 should include City of CoppelI Standard Details in the list of documents the
contractor is required to have on site at all times.
c) Add to Note 8 the following sentence: No lane of traffic shall be closed before 9:00
a.m. or after 3:30 p.m.
Site Plan
10. Typical parking spaces should be 9'x19'. Refer to the zoning ordinance for variance
requirements.
Paving Plan
11. All details on this sheet and in the construction plans that are included in our Standard
Details should be removed from the plans. The contractor is required to have a copy
of the City of Coppell Standard Details on the job site at all times during construction.
12. Paving Legend: Thc standard for paving in Coppell is Class "C" concrete, or 3600
psi.
13. The "Paving General Notes:" should be modified as described:
a) Note 2: Refer to the Standard Details for the sub-grade preparation requirements.
(Lime stabilization is required.)
b) Note 3: Sealant material to be self- evehng s 1icone sealer per the Standard Details.
c) Note 9: Refer to the Standard Details for joint spacing requircments.
Grading Plan
14. Provide details for the modifications to the retaining wall on the northern side of the
property. A design by a P.E. will be required if the wall is greater than 4' in height.
Drainage Area Map
15. Drainage areas 1, 2, 3 and 4 are proposed to drain to the inlet on Denton Tap Road.
This appears to be more flow, than the inlet was designed for. Perform an analysis on
the existing Denton Tap Road system and provide documentation that it will be able
to handle the proposed flow.
Drainage Plan
16. A connection to the inlet on Denton Tap Road was made during the development of
Grandy's. Try to utilize the existing connection by connecting to the existing 18"
RCP on private property.
17. Clean-outs are recommended at the locations where the roof drains adjoin the
proposed 18" RCP storm drain.
Storm Sewer Profiles
18. ls the proposed cover adequate for the 18" RCP?
Water and Sanitary Sewer Plan
19. The proposed location of the fire hydrant and FDC is not readily accessible to the Fire
Department due to the slope of the driveway. Consider placing the new hydrant and
FDC at the western driveway and tapping into the 8" water line that runs along the
southern side of Fitness Court as shown in the mark-ups.
20. The fire line and DDC should be 8" instead of 6". Tap the fire line for the private
hydrant after the DDC; this tap can be 6".
21. The DDC should be placed in a 25'x25' easement (as noted under Replat 1 of 2,
Comment 4).
22. The FDC line is a separate line and should not be connected to the fire line. The FDC
line should be 4" minimum.
23. The "Water Line General Notes:" should be modified as described:
(a) Note 1: Remove "unless otherwise noted."
(b) Note 7: Change "(1) Year" to "(2) Years."
(c) Note 10: Change "Two (2) Feet" to "Three (3) Feet."
(d) Note 16: Change to "Fire Hydrants shall be installed per City of Coppell Standard
Details."
24. Refer to other miscellaneous comments in the mark-ups.
Erosion Control plan
25. Steel posts and wire-backing are required for silt fencing.
26. Erosion Control General Note 2.: Stabilized Construction Entrance shall use 3"-5"
diameter crushed rock.
27. Construction Sequence: Grading work only may be performed under an Early
Grading Permit. A Construction Development Permit must be obtained for any utility
or paving work (this permit also includes grading). Include "Obtain Construction
Development Permit" in the sequence, or change "1. Obtain Grading Permit" to "1.
Obtain Construction Development Permit."
Landscape Plan
28. Landscape and Irrigation Plans should be removed from the civil drawings. Those
plans are not reviewed or approved by the Engineering Department. They should be
submitted to the Building Inspections Department for approval.
Please make the necessary changes and submit these marked-up plans and two sets of
revised plans to the City for review, lfyou have any questions, please contact this office
at your convenience.
Sincerely,
Charlene La Matti~a, E.I.T.
