Act 167

LVPC has started its initiative to create a consistent, up-to-date Act 167 stormwater management plan and global best management practices ordinance for the Lehigh Valley for two counties, 15 watersheds, and all 62 municipalities. This effort will:

• Regulate the impacts of subdivision and land development activities 
• Ensure best management practices including the expansion of green infrastructure 
• Identify and develop a plan to mitigate adverse impacts on equity communities
• Include hydrologic modeling 
• Assess and predict development patterns 
• Include a global stormwater management ordinance update 

The project will also incorporate state-of-the art green infrastructure, riparian buffer, low impact development, and water balance standards into the new global Act 167 ordinance to maximize the preservation of natural resources and create “green infrastructure first” requirements for stormwater management practices. Climate change impacts will also be built into the global ordinance to better regulate storm runoff impacts over time and enhance resiliency. DEP’s guidance for meeting National Pollutant Discharge Elimination System Post Construction Water Quality requirements will be added to assure compliance with Municipal Separate Storm Sewer System (MS4) permits.
