Design goals Design goals • Maximize runoff collection area, including Maximize runoff collection area, including roofs of adjacent buildings • Use the runoff to transform a blighted lot into Use the runoff to transform a blighted lot into a community asset/park • Use the project as an opportunity to Use the project as an opportunity to demonstrate multiple GI opportunities in Newark • Monitor project performance in a low cost and affordable way
Design Process Design Process • Two community charettes (including participation of participation of school children) • Final design • Final design incorporates community goals: y g – Water features and planting beds – Outdoor classroom d l

Water quality monitoring Water quality monitoring Monitoring g Description p Locations 1 Subsurface cistern 2 Test well in the center of the permeable pavement 3 Blow off valve for subsurface detention crates 4 Grey solo rain barrel 5 Treadle pump discharge into barrel line for reuse 6 6 Re se spigot at end of barrel line Reuse spigot at end of barrel line
Water Quality sampling Water Quality sampling • Water quality q y component intended to complement hydrologic monitoring monitoring • GI measures not intended to target intended to target pollutant reductions • System designed to influence discharge volume
GI train 1: Station 1 Station 2 Station 3
GI Train 2: Station 3 Station 4 Station 5
Water Quality Results: indicator bacteria
Water Quality Results: T, pH Water Quality Results: T, pH
Conclusions Conclusions • Urban vacant lots Urban vacant lots present a wide range of “green” opportunities – Community driven design – Urban revitalization U b it li ti – Runoff reduction – Aesthetic/recreational – Aesthetic/recreational improvement – Educational opportunity
