Erika Bridges:
The purpose of this letter is to acknowledge that the construction plans for the utility
improvements, for the above referenced project, to the best of my knowledge, do not deviate
from the latest B /CS Design Guideline Manual with the following exception.
• Minimum pipe slope of 0.50% along Sanitary Sewer Line "S l" between Sta. 5 +70.29 and
Sta. 9 +17.09. However, as stated and calculated in the Water & Sanitary Sewer Report
the pipe velocity, at peak flows, is above 2.0 fps.
• The two (2) segments of Sanitary Sewer Line "S4" installed in this phase of construction,
do not meet the minimum flow velocity of 2.0 ft/s at peak flow conditions. The design of
these lines comply with minimum size, type and slope, however, the low number of
dwelling units discharging to these lines prevent peak flows from reaching a flow
velocity of 2.0 ft/s;
I also acknowledge, to the best of my knowledge that the details provided in the construction
plans are in accordance with the B /CS Standard Details.
