RE: Trinity Shores
Dear Mr. Jahvani:
The City of Coppell has completed a walk -thru on the water, sewer, paving and drainage facilities in the
referenced project. Listed below are the results of that walk -thru.
There were thirteen items of deficiency to be corrected on the water and sewer facilities. All those items
have been corrected. The following items remain to be corrected on the paving and drainage facilities:
1. Rout and seal all random cracks.
2. Round off end of curbs at Sandy Lake Road.
3. Remove tack strip and seal around storm drain manhole at Station 1 +98, Line ST -2.
4. Remove interior forms from the above manhole.
5. Clean the street.
As we discussed in the field, you still have extensive grading work to perform on the house pads and in
the drainage easements, permanent SWPPP must be installed and maintained, and the screening wall must
be installed. We are in need of maintenance bonds in the amount of 50% of the contract value and for a
two -year period to cover all of the improvements within city right -of -way or easements and an erosion
protection bond to cover 100% of the cost of permanent erosion protection. An excerpt from City of
Coppell Ordinance No. 91514 addressing that particular requirement is enclosed for review. We are also
in need of "as- built" plans that reflect all changes made during the course of the project. Additionally, I
urge you to install suitable barricading at Sandy Lake Road until the proper traffic control can be
installed.
Thank you for your cooperation during this construction, and if I can be of help, please feel free to call me
at 972 - 304 -3685.
Sincerely,
arr amp r.

based on scientific, engineering, and economic
considerations. This ordinance does not imply that
erosion and sedimentation controls will survive inundation
by runoff from storms or that land below such controls
will be free from flooding or flood damages. This
ordinance shall not create liability on the part of the
City of Coppell, or any officer or employee thereof, for
any flood damages, or erosion or sedimentation damages,
whether to persons or property, that result from reliance
on this ordinance or any administrative decision lawfull
made thereunder.
F. SURETY FOR- PEOMENT EROSION CONTROLS IN NEW
;he applicant shall provide a surety in the form of cash,
/certificate of deposit, surety bond, or irrevocable letter
of credit acceptable to the City to insure that vegetative
cover and other permanent erosion control measures are
installed, maintained, and functioning properly up to a
two (2) year period from the date of final acceptance of p
the dedicated streets and /or utilities by the City of
Coppell. This surety shall be given to the City before
the final acceptance of the streets and /or utilities.
This surety shall be in the amount estimated by the
Developer, which is 100 percent of the cost of
constructing and maintaining the permanent erosion
controls for a two -year period. However, such estimate is
subject to review by the City Engineer and may be "
rejected, and the surety not accepted, if the City
Engineer deems the estimate not to be a reasonable
approximation of the costs of constructing and maintaining
the erosion controls.
Should the vegetative cover die or become sparse or the
erosion controls fail to be maintained or are not
functioning during this two -year period, the City may
notify applicant in writing. The applicant has ten (10)
days after being notified to begin correcting the
problems. If no corrections are started, the City may
make the necessary repairs by exercising the surety or
billing the applicant. If at the end of the two -year
period the vegetative cover is still not established or is
sparse, or the erosion controls are not functioning, the
City may exercise the surety and have the erosion controls
installed and established.
The above procedures for ensuring that
established shall apply to all projects,
the vegetation is the long -term maintenance
of the City. Any vegetative cover which is
a permanent part of the improvement project
acr`pted by the City until the growth has b4
vegetation is
whether or not
responsibility
planted and is
will not be
:en established
