Utilization of Park Areas for Flood
October 12, 1988
ABQ Development
A meeting was held at Coppe11 City Hall on October 4, 1988 to
discuss the possibility of partial utilization of undeveloped
Park areas near the Parks of Coppe11 for flood plain storage that
would offset flood storage depleted by proposed reclamation in
the Parks of Coppell.
In attendance with the City of Coppe11 were:
Ms. Shohre Daneshmand, Civil Engineer
Mr. Russell Doyle, City Engineer
Mr. Steve Goram, Director of Public Works
Mr. Richard Diano, Park Foreman
Mr. Steven M. Morton, Chief of hand Development (part-time)
Ms. Taryon Bowman, Planning & Zoning Coordinator (part-time)
Also in attendance were:
Mr. Kevin Peiffer, Ginn, Inc.
Mr. Jerry Parche', Jerry Parche' Consulting Engineers
1. I explained to the staff members that new regulations of the
U.S. Army Corps of Engineers for obtaining a Section 404
permit required that, if areas under jurisdiction of Section
404 are proposed to be filled as part of a reclamation
project, then the flood plain storage depleted by the
project must be replaced. I advised the City that, due to
the financial hardship this requirement will impose on
development of the Parks of Coppell property west of Denton
Tap Road, if a Section 404 Permit is required, ABQ
Development has asked me to explore the possibilities of
creating additional flood storage on undeveloped park.
property located in the Denton Creek flood plain near the
project site.
2. I advised the City staff members that ABQ Development would
provide compensation to the City if additional flood storage
could be located on the park property. Appropriate
compensation may consist of park improvements or monetary
compensation. Also ABQ wishes to minimize impacts that the
additionel flood storage would have
in the park. ~2YOR COUNCIL

The purpose of the meeting today is to discuss which park
lands may be available for additional flood storage and any
constraints on grading in park property that may exist.
4. I presented a work map we had prepared showing approximately
32 acres of park land north of Parkway Boulevard and east of
Denton Tap Road that I thought may be available for
regrading in order to provide more flood storage· The land
is currently in the Denton Creek flood plain, undeveloped
and mostly cleared of trees. Two lakes currently exist on
the property.
5. Steve Goram and Richard Diano stated that a park grading
plan was prepared in 1985. A Master Recreation Plan for
this area was agreed to between Univest and the City Council
in 1985. Mr. Diano indicated that he would get me a copy of
the Park Grading Plan.
6. Steve Goram indicated that there was serious concern among
the City Council regarding the amount of excavation being
performed by Univest in the park property when this work was
underway a few years ago.
7. Richard Diano will check with the Texas Parks and Wildlife.
Department on whether a Parkland Conversion may be required
to create more flood storage in the park.

Mr. Goram and Mr. Diano indicated that park lands west of
Denton Tap Road were not available for additional flood
storage. They indicated that this area of the park is fully
developed.
Mr. Goram indicated that the City will need to know how any
regrading on park property will affect the frequency of
inundation.
I indicated to the staff that the maximum amount of
additional storage ABQ is seeking on park property is
approximately 165 Ac. Ft. under 500-year flood conditions in
Denton Creek.
Richard Diano stated that the City asked Univest to install
flap gates east of Denton Tap Road on drainage pipes located
through high ground between the park property and Denton
Creek. Prior to installation of these gates, Mr. Diano
indicated that the park property was almost continuously
flooded from high water in Denton Creek resulting from
reservoir releases or runoff.

cc:
I suggested that since the park property was protected from
minor floods in Denton Creek by high ground and flap gates
on drainage structures between the creek and the park, the
frequency that the park is flooded should not be impacted by
excavation of park land to create flood storage for the 100-
year and 500-year floods.
City staff members also indicated that geotechnical studies
should be performed to determine ground water levels in this
area and the effects of the groundwater in any proposed
excavation scheme.
The project will need the approval of the Coppe11 Park
Board. Mr. Ed Reeve is the current Park Board Director.
