The City & County of Broomfield must develop, implement and enforce a program to reduce pollutants in any
stormwater runoff from construction activities that result in a land disturbance of greater than or equal to
one acre. Reduction of pollutants in stormwater discharges from construction activity disturbing less than one
acre must be included in the program if that construction activity is part of a larger common plan of development
or sale that would disturb one acre or more.
