2 Outline 1.SMB JG7 WMP Group Overview 2.Water Quality Priorities 3.Pollutant Reduction Strategy 4.Selected Watershed Control Measures 5.Outreach and Stakeholder Input on Draft WMP

3 SMB JG7 WMP Group Overview WMP Group: - City of LA area - 977 acre (16.6% of entire JG7) - LACFCD - storm drains Receiving Waters: - Santa Monica Bay 3

4 SMB JG7 WMP Group Overview 4 Destroyed in landslide Two Bacteria Monitoring Stations Anti-degredation

5 Water Quality Priorities Category 1 WBPCs 5 Category 1, Highest Priority: All Applicable TMDLs SMB Dry Weather Bacteria TMDL - Summer Dry: 2006 - Winter Dry: 2009 SMB Wet Bacteria Weather TMDL - 2013 SMB Offshore/Near Shore Debris - 2020 SMB Toxics (PCB/DDT) - EPA TMDL

6 Water Quality Priorities Category 2 and 3 WBPCs Category 2, High Priority: No other 303(d) WBPCs listed at this time Category 3, Medium Priority: No other exceedances of WBPCs at this time 6

7 Pollutant Reduction Strategy Bacteria: in compliance - Anti-degradation sites; no reduction required - Maintain compliance Trash: TMRP developed - 57 catch basin retrofit with screens by December 2015 (26%) - Remaining 161 cover and/or insert retrofits (100%) by July 2016 PCBs/DDTs: in compliance - Maintain current baseline 7

8 Selected Watershed Control Measures LID Ordinance: Effective May 2012 Green Streets Policy: Adopted July 2011 MCMs: ongoing to meet Permit requirements Structural BMPs: limited opportunities due to geographic constraints, landslide hazards. Adaptive management process in coordination with CIMP 8

9 Outreach and Stakeholder Input on Draft WMP Public outreach meeting held on April 10 th in combination with all City-wide EWMPs/WMPs Stakeholder input received on Draft WMP 9

10 Summary Several category 1 WQ priorities, but no categories 2 and 3 Currently in compliance through existing measures CIMP Implementation - Receiving water monitoring - NSW outfall monitoring - SW outfall monitoring - Cost: $330k for first 3 years Adaptive management is key: revise WMP if data from CIMP would demonstrate persistent exceedances of RWLs and WQBELs 10
