UNH Stormwater Center Develops a Hybrid Bioretention Template

Body: 

The University of New Hampshire Stormwater Center (UNHSC) has developed an innovative hybrid bioretention template for use by municipalities and others to address stormwater runoff and achieve pollutant load reductions.

The template combines up-to-date design information for ithe inclusion of an internal storage reservoir in conventional bioretention systems to address nitrogen control while still taking advantage of biofiltration and infiltration unit operations to address other pollutants and volume reductions.
