Wide Verge Low impact turf swale design using Permapave grates.

Permapave provides trafficable surface on road verge, soil aeration, and 100% gross pollutants.

Permapave side entry to bio-retention street tree planters.

Regular side entry (with slightly elevated entry) in case of flood overflow.

Risk mitigation should Permapave block.

Permapave planters receive first flush, filter stormwater and retain nutrients.
