Environmental Regulations Are Changing

New in 2025: Key regulatory updates are reshaping how municipalities, developers, and engineers must approach projects. Staying ahead of these changes helps you make smarter decisions and avoid costly delays.

Two updates to watch:

LEED v5 Certification

The U.S. Green Building Council (USGBC) will roll out LEED v5 in early 2025, introducing the most significant update to green building standards in a decade. This new version raises the bar for sustainability, health, and climate impact.  This update encourages developers, municipalities, and engineers to prioritize sustainability in construction and infrastructure projects.

MS4 Stormwater Regulations

The Pennsylvania Department of Environmental Protection (DEP) oversees the Municipal Separate Storm Sewer System (MS4) Program, which regulates stormwater runoff to protect water quality. In 2025, key updates were introduced to enhance stormwater management and climate resilience.
