METHODS GOOD BETTER. BEST Vegetation/Green Space Use of climate- appropriate, eco-friendly vegetation (groundcover, shrubs, and trees) / green space 5%-15% covered by new climate-appropriate vegetation Use of native, climate- appropriate, eco-friendly vegetation (groundcover, shrubs, and trees) / green space 16%-35% covered by new native vegetation Establishment of plant communities with a diversity of native vegetation (groundcover, shrubs, and trees) / green space that is both native and climate-appropriate More than 35% covered by new native vegetation Increase of Permeability Installation of vegetated landscape – 25%-49% paved area removed Redesign of existing impermeable surfaces and/or installation of permeable surfaces (e.g. permeable pavement and infiltration trenches) Installation of vegetated landscape – 50%-74% paved area removed Improvements of soil health (e.g., compaction reduction) Installation of vegetated landscape – 75%-100% paved area removed Creation of well- connected and self- sustained natural landscapes with healthy soils, permeable surfaces, and appropriate vegetation Protection of Undeveloped Mountains & Floodplains ● Preservation of native vegetation ● Minimal negative impact to existing drainage system ● Preservation of native vegetation ● Installation of new feature(s) to improve existing drainage system ● Creation of open green space ● Installation of features to improve natural hydrology Creation & Restoration of Riparian Habitat & Wetlands •Partial restoration of existing riparian habitat and wetlands •Planting of climate appropriate vegetation - between 5 and 15 different climate- appropriate or native plant species newly planted •No potable water used to sustain the wetland ● Full restoration of existing riparian habitat and wetlands ● Planting of native vegetation - between 16 and 30 different native plant species newly planted ● No potable water used to sustain the wetland ● Full restoration and expansion of existing riparian habitat and wetlands ● Planting of plant communities with a diversity of native vegetation – greater than 31 native plant species newly planted ● No potable water used to sustain the wetland New Landscape Elements Elements designed to capture runoff for other simple usage (e.g. rain gardens and cisterns), capturing the 85th percentile 24-hour storm event for at least 50% of the entire parcel Elements that design to capture/redirect runoff and filter pollution (e.g. bioswales and parkway basins), capturing the 85th percentile 24-hour storm event from the entire parcel Large sized elements that capture and treat runoff to supplement or replace existing water systems (e.g. wetlands, daylighting streams, groundwater infiltration, floodplain reclamation), capturing the 90th percentile 24-hour storm event from the entire parcel and/or capturing off-site runoff Enhancement of Soil Use of soil amendments such as mulch and compost to retain moisture in the soil and prevent erosion Planting of new climate- appropriate vegetation to enhance soil organic matter Use of soil amendments such as mulch and compost that are locally generated to retain moisture in the soil, prevent erosion, and support locally based composting and other soil enhancement activities Planting of new native, climate-appropriate vegetation to enhance soil organic matter Use of soil amendments such as mulch and compost that are locally generated, especially use of next-generation design with regenerative adsorbents (e.g. woodchips, biochar) to retain moisture in the soil, prevent erosion, and support on-site composting and other soil enhancement activities Planting of new native, climate appropriate vegetation to enhance soil organic matter
