Low-impact stormwater management systems in the cold climate of New Hampshire had less seasonal decline in performance than conventional best-management practices (retention ponds, swales). LID systems included subsurface infiltration, biorentention, gravel wetlands, a porous asphalt system, a street tree, and seven proprietary systems. Frozen filter media did not reduce performance.
