RE:
Grapevine Springs Park
(Open Space Site)
Dear Mr. Goram:
Summarized belowis our Understanding of the points agreed upon at
our meeting May 7, 1992, with representatives of the City of
Coppell in connection with the captioned project:
The original objective to install erosion protection along
Grapevine Creek and reclaim the eroded part of the park island
was questioned on the basis that the City of Coppell felt that
the proposal would result in a rise in the 100 year flood
elevation which would require FEMA and the City of Coppell
variance of their regulations and ordinances. The City of
Coppell agreed to consider the Dallas County erosion control
plans if accompanied by a hydrology study.
The City Engineer indicated that the Ckty of Coppell would
a~ree to concrete riprap along the existina left bank of
Grapevine Creek, shaped to a 2:1 slope - preferably with earth
tone color added.
Mike Sharp indicated he would be unable to build the riprap;
therefore, contract plans and specifications and receipt of
contractor bids will be required.
The City of Coppell requested, however, that they be given an
opportunity to meet with FEMA with a set of erosion control
plans showing reclamation of eroded park island to see if FEMA
would "sign-off" on the plans as drawn.
Se
The City Engineer agreed to check with FEMA to see if
installation of a pre-engineered, prefabricated pedestrian
bridge installed at the same (or slightly higher) elevation
as the old foot bridges would be acceptable. This elevation
would be approximately 10 feet beneath the 100 year flood
elevation.
