Re: Twality Middle School Renovation Project Stormwater Facilities
MMD2003 -00017
Dear Hap:
The engineering design for stormwater quality at Twality Middle School incorporated two (2)
filter catch basins manufactured by Stormwater Management, Inc. Detention was provided
by a small surface pond and a flow control manhole. I visited the site at various stages of
construction and confirm that the installation of the quality and detention facilities are in
conformance with the design and specifications.
Sincerely,
