Tag: ms4 permit

The U.S. Clean Water Act (CWA) requires that local governments in urbanized areas (as defined by the Census Bureau) obtain stormwater discharge permits for their drainage systems.[16][17] Essentially this means that the locality must operate a stormwater management program for all surface runoff that enters the municipal separate storm sewer system (“MS4”). EPA and state regulations and related publications outline six basic components that each local program must contain.

Underground Stormwater Storage Case Studies

Underground Stormwater Storage Case Studies

Underground retention and detention systems continue to increase in popularity as urban and suburban infill prompts careful consideration of proposed land uses on high-value real estate. Placing stormwater management underground frees up space for higher value land uses and greater return on investment. Additionally, trends toward water awareness and reclamation,

An Integrated Watershed Assessment Tool for Restoration

An Integrated Watershed Assessment Tool for Restoration

The importance of water and water quality has become a heightened global concern as human populations grow, industrial and agricultural activities expand, impervious surfaces increase, and climate change threatens. The adoption of the federal Clean Water Act and related state and regional environmental regulations imposed on municipal separate storm sewer

Surf and Turf

The promulgation of trash total maximum daily loads (TMDLs) and associated requirements in municipal stormwater permits have instituted the need to characterize anthropogenic trash on land and water to support trash-related management decisions. Trash is widely recognized as a serious water-quality concern. Trash in the Los Angeles River has been

Simplifying Stormwater Detention Design With Precast Concrete & Hydrologic Modeling

Simplifying Stormwater Detention Design With Precast Concrete & Hydrologic Modeling

Increasingly, stormwater management for buildings and facilities is going underground. Offering smaller footprints, larger stormwater capture, and better flow mitigation, many water utilities and facilities are looking to incorporate underground precast stormwater detention/retention systems at their sites to meet NPDES MS4 permit and Low Impact Development (LID) requirements. But…how do you
