Acknowledgement of City Standards
RATE No. 242 -0405
Josh Norton:
The purpose of this letter is to acknowledge that the construction plans for the public
infrastructure 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 exception of the following
items:
❖ All segments of sanitary sewer line installed for 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,
• The typical bottom slope of the detention pond built in this phase of construction does not
meet the minimum cross slope of 5.00 %. The proposed detention pond is specified with a
bottom cross -slope of 2.00 %, based on design constraints of the detention pond that
cannot be changed.
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.
Please do not hesitate to call if you have+ `y questions.
Sincerely,
.. .......-\ OF OF T EX
