Goals are the broad general purposes of the detention pond and its outlet works. A typical goal for a detention pond would be to help manage storm runoff so as to maintain historic conditions of peak runoff and to maintain pre-development water quality in the downstream tributary. An objective is a defined and specific end result to be achieved by the construction of the detention pond. For instance, an objective could be to mitigate post-urban-development peak runoff values for the range of return frequencies from 2 years to 100 years to within 20% of the historic runoff peaks. Another objective might be to collect 60% of the silt load generated by an urban development during the construction phase.
