Medical Offices MS4 Compliance
Aliso Viejo, California

CDS, Modular Wetlands and UrbanPond Manage Stormwater

A healthcare provider's new Aliso Creek Medical Offices development increased impervious cover and required a stormwater management solution. A treatment train that integrates pretreatment, biofiltration, and detention was designed to include a CDS® Hydrodynamic Separator, two Modular Wetlands® Linear Biofiltration systems and an UrbanPond® concrete detention system.

CR 675 over West Crystal River

Glen Arbor, Michigan

Big R Bridge Restores Fish Passage

Three undersized and deteriorating barrel culverts were replaced with a Big R Bridge® Modular Rolled Girder which provided unimpeded stream flow, eliminated barriers for fish and wildlife and improved the safety of river enthusiasts.

Wallace, North Carolina

CORLIX Replaces Critical Culvert

Along Deep Bottom Road, a critical culvert was replaced with a CORLIX® corrugated aluminum pipe, restoring access for local hog farmers to receive feed trucks.

	Leading When Failure Is Not an Option \| Part 2

	Infrastructure leadership carries a unique ethical burden. When a storm system fails, basements flood. When a culvert collapses, roads close – or worse. When wastewater containment systems fail, ecosystems suffer. These outcomes are not abstract. They affect real people. Leaders in this industry must foster a culture where: safety is non-negotiable, specifications are respected, installation guidance is clear and enforced and field feedback is welcomed and acted upon.

Stormwater for Housing and Water Quality

Make Stormwater Work for Housing—and Water Quality

The recent Executive Order on housing affordability has reignited a familiar debate: are stormwater regulations driving up the cost of new homes? Critics argue that compliance adds thousands of dollars per unit with unclear benefit. Defenders respond that these requirements protect waterways, reduce flooding, and provide long-term value. Both perspectives contain truth—but neither fully addresses the underlying issue.
