Act 167

Pennsylvania’s Stormwater Management law, Act 167 of 1978, requires counties to prepare stormwater management plans on a watershed-by-watershed basis. The plans must be developed in consultation with the affected municipalities. Standards for control of runoff from new development are a required component of each plan and are based on a detailed hydrologic assessment. A key objective of each plan is to coordinate the stormwater management decisions of the watershed municipalities. Implementation of each plan is through mandatory municipal adoption of ordinance provisions consistent with the plan. Within Lehigh and Northampton counties, the Lehigh Valley Planning Commission prepares plans on behalf of both counties.  

Lehigh Valley Watershed Assessment + Global Model Ordinance

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.

Legacy Act 167 Plans

The following Act 167 plans are the previous versions of the plans developed by the LVPC on behalf of Lehigh and Northampton counties for the 12 watersheds that have received ordinance updates related to water quality since 2004. These plans include the complete documentation of the watershed as required by Act 167 that was not reproduced in the water quality updates. The LVPC advisory review of stormwater management designs for proposed land developments in these watersheds is based on the criteria documented in these plans and ordinances.
