RE: Coppell Middle School-Easn
Track & Tennis Court Additions
Dear Mr. Martin,
Coppell Independent School District requests the following
substitution for the standard City requirement:
1. The track storm sewer system will use a 12-inch
~lpe instead of an 18-inch pipe.
2. The 12-inch pipe will be ADS High Density
Polyethylene, smooth lined pipe instead of
Reinforced Concrete Pipe.
The storm sewer for the track is to be a private system,
maintained by the District. Ail public storm sewer will be
constructed of Reinforced Concrete Pipe and will be larger
than the required 18-inch minimum.
Sincerely,
Wilburn O. Echols Jr.,
Superintendent
