As one of Nebraska's MS4 permitted counties, Douglas has a county wide stormwater management plan which includes post-construction and maintenance requirements. These standards incorporate state level regulations.
The purpose of this MCM is to place the greatest value on retaining (and thus “treating”) the maximum amount of stormwater on site through good site design and green infrastructure and to ensure the water remains continuously “treated” if it leaves the property. With the implementation of specifically required Stormwater Treatment Practices (STP’s) water will have the best chance of being and/or remaining clean prior to entering receiving waters. These STP’s will be monitored and maintained based on official Maintenance Agreements.
