3 Overview of NYC s GI Program

4 Overview of NYC s GI Program $192 million is budgeted for green infrastructure in combined sewer areas through A multi-pronged approach toward widespread implementation in priority combined sewer overflow (CSO)tributary areas through: 1. Area-Wide Contracts 2. On-site Construction 3. Neighborhood Demonstration Areas 4. Green Infrastructure Grant Program 5. Adaptive Management

5 Overview of NYC s GI Program Phasing the Benefits Incremental benefits of GI begin to accrue at the onset and grow over time.

6 Overview of NYC s GI Program Spreading the Costs Multi-pronged approach for implementation necessitates both public and private investment. Estimated costs of different CSO control strategies in NYC over 20 year period.

7 Overview of NYC s GI Program GI Integration into CSO Program Modified 2012 Consent Order substitutes more costeffective grey and green infrastructure projects to achieve additional CSO volume reductions. Target is to manage 1 of runoff from 10% of impervious surfaces in combined sewer areas by Green Infrastructure application rates and milestone schedule. 12% 10% 8% 6% 4% 2% Initial 1.5% Additional 2.5% Additional 3.0% Final 3.0% 0%

8 Overview of NYC s GI Program Adaptive Management Program involves an adaptive management approach toward target GI application rates based on postconstruction monitoring, modeling and reporting. Corrective Measures Review of Actual Benefits & Costs Reporting & Info Sharing Program Planning Ongoing R&D Projections of Benefits & Costs Performance Standards & Metrics Monitoring Data Assessment Program Implementation

9 Overview of NYC s GI Program Post-Construction Monitoring of Pilot Projects 25 pilots at 18 locations constructed during and 2012 monitoring data analysis and reports completed and describes: Performance Maintenance Costs Results applied to current site selection and design processes. NYC s pilot monitoring locations in combined sewer areas of Brooklyn, Queens and the Bronx.

10 Overview of NYC s GI Program Post-Construction Monitoring of Pilot Projects (Sample Results) Volume Retained 110% 100% 90% 80% 70% 60% 50% 40% 30% 20% 10% 0% North & South Conduit Project Type: Bioretention Area: 1,300 sq ft Capacity: 200,000 gal from CSSs Constructed: 2011 Storms Monitored in 2011: Rainfall Depth (in)

11 Overview of NYC s GI Program Post-Construction Monitoring of Neighborhood Demonstration Projects

12 Justice Avenue Stormwater Best Management Practices BMP Pilot Project Environmental Benefit Project (EBP) funded by New Elmhurst, Queens, NY York State Department of Environmental Conservation EBP Settlement Fund Gowanus and Flushing Watershed Initiative (GFWI) Grant Program developed by New York City Department of Environmental Protection (NYCDEP) Gowanus Watershed: 1,758 acres Flushing Bay and Creek Watershed: 19,560 acres EBPs of $1.45M per Watershed (stormwater & LID) Project identified by Educational Institution and Non- Profit Organization

13 Justice Avenue Stormwater BMP Pilot Project Conception and Objectives: Initial identification by Columbia University/HDR and NYC Audubon Society Potential for improving stormwater quality into Flushing Bay Watershed Potential for landscape improvements identified Potential for Improving habitat of birds

14 Justice Avenue Stormwater BMP Pilot Project Team: NYC DEP Bureau of Environmental Planning & Analysis NYC Audubon Society Grantee HDR Scape/Landscape Architects

15 Justice Avenue Stormwater BMP Pilot Stormwater Detention System for 1 rainfall event Improve habitat of smaller species 3-yr Monitoring and Maintenance by Grantee

16 Justice Avenue Stormwater BMP Pilot Catch basin replacement Replacement of poor permeability soils with engineered soils Under-drain to flow and water quality monitoring manhole Landscape Improvement Increased Habitat (insect and smaller species)

17 Justice Avenue Stormwater BMP Pilot 60% Design Advance to 90% for Construction Construction (Anticipated Summer 2013) 3-yr Monitoring and Maintenance Period: Flow rate, Oils & Greases, TSS Rags, debris, and trash clean-up within site Planting maintenance

18 NYCDEP s GI Grant Program Partially funded by NYSDEC EBP Settlement Fund. DEP awarded over $10 million in funding to 30 different partners since Recipients contributed $5.4 million in matching funds. Projects will prevent 15 MG of stormwater from entering the combined sewer system each year grant recipients announced May 1, Rooftop Farms/Green Roofs Brooklyn Navy Yard - Building No. 3 Rain Gardens/Permeable Pavers Queens College Remsen Hall

19 Grant Funding for GI Projects in Ohio

20 Grant Funds for GI Projects Factors to be Eligible for Grant Projects: Available Watershed Information (i.e. hydraulic modeling, subsurface conditions and information on the water quality in the receiving water body). Relevance of the proposed improvements in terms of impact to the watershed or immediate water body s water quality. Relevance of the proposed improvements in terms of impact to the community. Support letters from non-profit organizations, local, state, and federal organizations. Support from local government and commitment to match funds and provide long term maintenance.

21 Grant Funds for GI Projects in Ohio Ohio Environmental Protection Agency: Clean Water State Revolving Fund (CWSRF), Green Project Reserve (GPR) Water Pollution Control Loan Fund Potential Sources for Grants and Loans Statewide Nonpoint Source Pollution Program Grants (Section 319h Program) USDOT s Transportation Alternatives Program (TAP) USEPA s Targeted Watershed Grants Program USDOE s Weatherization and Intergovernmental Program Great Lakes Restoration Initiative Grants Program Ohio Development Services Agency Alternative, Stormwater Infrastructure Loan Program Ohio Department of Natural Resources (ODNR) Coastal Management Assistance Grants Other GI Information Resources: USEPA Green Communities: The Low Impact Development Center:
