Regulatory Compliance

The City of Lancaster’s stormwater management program is designed to meet the requirements of federal and state laws and regulations while also protecting the health and safety of Lancastrians.


It has several key components, including:


– Education and Outreach

– Public Participation

– Illicit Discharge Detection and Elimination

– Regulation of construction site runoff

– Regulation of stormwater after construction

– Pollution Prevention / Good Housekeeping of City facilities and operations


The City of Lancaster relies on a formal partnership (Memorandum of Understanding) with the Lancaster County Conservation District to comply with these regulatory obligations.
