Green Infrastructure Retrofit

Project Overview

A leading regional university partnered with Total Stormwater Solutions to meet new VSMP permit requirements triggered by a campus expansion. Rather than traditional gray infrastructure, the university chose a green infrastructure approach that would also enhance campus aesthetics and contribute to their LEED certification goals.

Scope of Work

• Site investigation and stormwater audit across 15 acres
• Design of six bioretention cells totaling 8,000 sq ft
• Installation of 12,000 sq ft of permeable interlocking concrete pavers
• Subsurface drainage system design and installation
• Native plant specification and planting plan
• VSMP permit application and agency coordination
• Monitoring system installation for compliance demonstration

Results

• 2 million gallons of stormwater captured annually
• 85% reduction in impervious runoff from target areas
• Contributed 3 LEED credits toward campus certification
• 95% plant establishment rate after first growing season
