Re: Riverchase Drive Phase II and III
Dear Mr. Daniel:
The City of Coppell has received and reviewed the referenced plans. Based
on your letter provided on March 11, 1992, the following items pertaining
to this project have already been completed:
1)
3)
4)
The R.O.W. has been dedicated.
The Phase I paving, drainage, and utilities are totally
complete.
The utilities and drainage for Phases II and III are complete
and in place. It is my understanding, based on our
conversation, the tops of the inlets have yet to be constructed
for Phases I1 and III.
The plans have previously been approved for construction.
However, our subdivision rules state "If construction has not
commenced within one year after approval of plans, resubmittal
of the plans may be required by the City Engineer for meeting
current standards and enGineerinG requirements."
Based on the above understanding of the current status of the project alld
the wording of the Subdivision Ordinance, the City of Coppell has the
following comments to offer:
1)
2)
3)
4)
The plan approval paragraph for the City Engineer's signature
should be provided.
A vicinity map and the limits of the project should be shown.
All standard construction details should be provided.
Each page of this set of plans should contain an engineer's
seal that is clear enough to read with a signature and a date.

The plans should clearly indicate what has previously been
constructed and what is being submitted for review.
The executed copy of the final plat should be provided with the
plans.
The specification for the paving stones should be clear enough
to read.
The intersection for the connection of Riverchase Drive to
Sandy Lake should be revised so that, when the additional
R.O.W. for Sandy Lake is obtained and Sandy Lake Road is
widened, the median section and the brick payer's on Riverchase
will not have to be removed and rebuilt. This will necessitate
moving the median and the paving stones approximately 25 to 30
foot further south away from the intersection of Sandy Lake
Road.
Notice the various comments on Sheet 4 pertaining to showing
the total footage of paving to be installed.
The profile of the existing multiple box culvert should be
shown on Page 5.
These plans have been resubmitted for review, therefore, all
referenced to record drawing should be omitted from the section
of the plans to be reviewed by the City. Also, as previously
indicated, it should clearly be noted on the plans what is
existing and what is proposed.
The drainage area map indicates that 6 - 8 X 4 mUltiple box
culverts are being provided. However, your construction plans
indicate that only 5 - 8 X 4 multiple box culverts were
constructed. Because the paving has not been constructed in
this area, the hydraulic data for the drainage basin for the
multiple box culverts should be provided with this set of plans
to verify the need for either five or six multiple box culverts.
Your letter indicates that all the drainage has previously been
installed. If that is the case, then Sheet 12 should clearly
indicate that. Also, all utilities shown in the profile view
should be shown in the plan view also.
Notice the various comments on this set of plans concerning the
water line installation. Please clearly indicate on the plans
if the entire water line has been installed per the previously
approved plans. If not, then please make corrections as noted

on the plans concerning the water line installation. As
previously indicated in meetings, even though the sewer line
has been completely installed, it will be required to be
televised prior to acceptance of this project.
15)
Please notice the comment on the landscape plans from the
Public Works department. Any comments concerning this should
be directed to either Rick Wieland or Steve Goram with the
Public Works department.
Once these comments have been corrected, the markup set of plans and the
revised set of plans should be resubmitted to the City.
If you should have any questions or comments, please feel free to contact
me at your convenience.
Sincerely,
Kenneth M. Griffin, P.E.
City Engineer
