Re: Sand Point Estates
Final Plat and Plans
First Review
Dear Mr. Griffin:
We have reviewed the final plat and construction plans of the Sand Point Estates
Addition to the City of Coppell prepared by CCN Engineering Corp., for Frank
Bamburg Building Company, Inc. The final plat and construction plans have been
prepared in general conformance with the City's Subdivision Regulations. However,
we have noted several items in need of correction prior to final acceptance. Our
comments are detailed on the attached final plat check list, the City of Coppell
Engineering checklist, and on the marked-up construction plans.
We will calculate the preliminary development fees for this addition and provide
you with a draft letter, once we have received the street sign assessment from
Public Works.
By copy of this letter, we are providing these comments to CCN Engineering Corp.,
and will hand them the marked-up plans and checklist at the December 31, 1991
Development Review Committee meeting.
We are available to discuss this project further at your conve~e~ce.
