RE: Water Flow Test at Otten Brothers Nursery on May 29, 1991
Dear Mr. Vang:
This letter will serve as confirmation of my recent water flow test conducted at
Otten Brothers Nursery located at West Wayzata Blvd. and Willow Street on the
above aforementioned date.
Enclosed is a copy of my water flow test report and fire protection water supply
analysis graph for your information. This water flow test report shows only one
of three tests conducted at the site, with this test considered the most
accurate of the three conducted.
I would like to thank you for all time and consideration for allowing this test
so that I could complete an automatic sprinkler grading for our client at their
new facility.
If you have any questions concerning my test, please do not hesitate in calling
my office at your convenience.
Sincerely,
451
