  Urban Stormwater Strategy
• 7.
  Urban Stormwater -Highlights  Current pace of restoration will not achieve target reductions  2-year restoration milestone set by what is currently in the pipeline  County strategy will account for: – Phase I NPDES – MS4 Loads – Non-regulated stormwater Loads – Construction
• 8.
  Urban Stormwater Strategy Approach  Account for progress made between 2009 and June 30, 2011.  Account for past actions not apparently credited – Stream Restoration – Shoreline Erosion Control  Determine how far current pace will take us (Capacity Analysis) and propose additional implementation actions to fill the gap (Gap Analysis).  Account for previously unaccounted for activities – Urban Nutrient Management law 1998 – Fertilizer Use Act of 2011 – Illicit Connection Elimination Program – Reduction in SSO due to Consent Decree progress – Redevelopment  Work with State and the CBP to determine BMP efficiencies
• 9.
  July 2011 –June 2013 2 – Year Restoration Milestones  63,174 linear feet of stream restoration  972 linear feet of shoreline enhancement  669 acres of SWM retrofits/conversions  Street Sweeping at current pace  Storm drain cleaning at current pace  6,125 acres – urban nutrient management (1998)  Watershed Association projects  SSO elimination (20% of current average overflow rate)  Redevelopment (estimated 200 acres over 2 years)  Possible (10 acres urban riparian buffer and 100 acres of upland reforestation
• 10.
  Enhancements for futureyears  Credit for Fertilizer Use Act of 2011  3X SWM Retrofit/Conversion Rate  5X Shoreline Enhancement Rate  2X Street Sweeping (based on better targeting)  2X Storm Drain Cleaning (based on better targeting)  3X Riparian Buffer Planting  3X Upland Reforestation  Credit for Illicit Conx Program (need to assess how)  Higher Credit for stream restoration and Shoreline Enhancement
• 11.
  January 2012 –December 2013 Programmatic 2 - year milestones  Fiscal: – Develop a Stormwater Utility Fee as required by Maryland State law.  Assure that such funding that is developed addresses both the capital and operational needs  Better Data – Continue to work with the expert panel on stream restoration credits – Continue to work with the expert panel on retrofit credits – Work with expert panel to develop a methodology for receive credits for Illicit Connection removal
• 12.
  July 2011 –June 2013 Programmatic 2 - year milestones  Tracking, Verification, and Reporting: – Develop a tracking mechanism to account for redevelopment pollutant load reductions – Develop a tracking mechanism to account for green field development and increase in pollutant loads – Develop a better tracking system to tie SSO reduction with sanitary sewer system remediation  New or revised programs – Develop a reforestation program that is not dependant on mitigation funds (Use Rural Residential Stewardship and Urban Tree Canopy Models) – Work with the State to develop and assess the options for an off-set program to address increased loads due to new development
• 13.
  July 2011 –June 2013 Programmatic 2 - year milestones  Coordination – Develop a mechanism for targeting street sweeping based on Neighborhood Source Assessments conducted for SWAPs – Work to surrounding jurisdictions to develop a “Trading in Time” Program with WWTPs to temporarily off-set urban stormwater load reductions.
• 14.
  Other Considerations  Targeting of restoration projects based on delivery ratios to the bay  Integration of restoration implementation to meet both the Chesapeake Bay TMDL and local TMDLs

  Local Nutrient TMDLs (2 EPA approved, 1 in development) Prettyboy Reservoir – 54% Phosphorus Reduction (15% Urban Reduction) Loch Raven Reservoir – 50% Phosphorus Reduction (15% Urban Reduction) Chesapeake Bay TMDL Nitrogen – 28.8% Urban SW Phosphorus – 43.4% Urban SW Reduction
• 17.
  Local Sediment TMDLs (4 EPA approved) Loch Raven – 25% (based on reducing reservoir sedimentation) Patapsco – 0 – 15.1% (stream aquatic life) Gwynns Falls – 23.5 – 44.6% (stream aquatic life) Jones Falls – 21.9% (stream aquatic life) Chesapeake Bay – no reduction allocation (water clarity)

  Bacteria TMDLs (7 EPA approved) Patapsco River 12.9 – 56.1% Liberty Reservoir 64.9% Gwynns Falls 67.2 – 99.9% Jones Falls 92.1 – 95.3% Back River 91.3 – 95.5% Prettyboy Reservoir 9.5 – 85.3% Loch Raven Reservoir 0 – 89.8%
