OL:
Please re -calculate the detention pond volumes using the FAA method. Stormwater
Utility compared the detention volume values obtained by the FAA method and compared
them to the values found in the report, and found a large difference. The FAA method
gives a more conservative estimate for detention storage; it is possible that the discrepancy
is due to a different rainfall hyetograph being used by your model. Please make sure that
the hyetograph complies with City criteria.
RESPONSE:
2. Water quality treatment measures should be added to the site in accordance with Land
Use Code section 3.4.3. It is recognized that the code references the City of Fort Collins
drainage criteria manual which in turn references Urban Drainage Manual Volume 3 with
respect to water quality treatment. The City recommends the use of a soft treatment such
as an extended water quality detention whenever possible.
RESPONSE:
Please see the redlined plan and report for additional review comments.
