RE: Common Area south of Copperstone Addition
Dear Mr. Clack:
Thank you for meeting with myself, Garreth and Homeowner's
Association representatives of the ;arding the common
area/floodplain on the south side of the Coppert~ ition.
The first item discussed was concernin
on the southwest corner of the
of the lots in the Copperstone Addition
such that it now ponds water to
Creek Section IV. Before

of the pond located

A survey of the perimeter of
be completed to determine the normal
per the survey, an estimate of the normal pool
provided on the City's 1992 topographic maps can be
the elevation of the east perimeter of the pond such
perimeter. By doing this, the water will drain to the east
instead of ponding to th~ south behind the homes, in the Village at Cottonwood Creek
IV.
Another issue discussed at the meeting was regrading the two storm drainage outfalls to
allow proper drainage. It was discussed that it may be necessary to survey possible
routes of the grading to ensure that once graded the storm drainage systems would
drain. Also, it was noted that there was not going to be any reseeding/resodding of any
areas, which are graded, but erosion control measures would be required as per the
City's ordinances and standards.
Please provide a cost for the items listed below. The cost should include surveying and
erosion control measures as previously mentioned.
Establish the normal pool elevation for the pond based on a determined elevation as
described earlier so that the water will drain east instead of ponding behind the
homes in Villages of Cottonwood Creek Section IV. Cost $
Regrade the two (2) storm drainage outfalls on the south side of the Copperstone
Addition located between Lots 16 & 17, Block E and Lots 21 & 22, Block E such
that they drain as previously described. Cost $
If you should have any questions concerning this issue please contact Garreth Campbell
or me at 972/304-3679.
Sincerely,
Michael A. Martin, P.E.
Asst. City Engineer
