Caltrans Trash Reduction Workplan

SF Bay Trash Control Requirements Permit Driver  CT Permit Attachment V – SF Bay Region-Specific Requirements Requirements  Full Capture – “…..any single device or series of devices that trap all particles retained by a 5 mm mesh screen and has a design treatment capacity of not less than the peak flow rate from a 1-year, 1-hour storm in the subdrainage area.”  Timely implementation within high trash generation areas: Install, operate and maintain full capture trash controls: –within CT R/W or –outside R/W in partnership with local MS4 permittees, and/or Enhance maintenance activities for storm drain systems in these catchments

Map of Roadway Segments within Region 2 1,100 Centerline miles (7,600 lane miles) 2,500 Bridges 3 Rest Areas 49 Park-n-ride lots

Trash Reduction Plan Objectives:  Identify High Trash Generation Areas  Prioritize areas for trash reduction measures (through retrofits, institutional controls, cooperative agreements, etc.)  Identify trash reduction strategy within the Caltrans NPDES Permit cycle (2018)  Identify trash reduction strategy for the long-term (post-2018)

Significant Trash Generating Areas Screen high-trash generation areas based on:  litter collection  Adopt-a-highway  Street Sweeping Develop Litter Collection Effort Map that serves as a starting point On-land visual assessment  Low  Medium  High  Very High  580 miles completed by 9/1/15

Mapping High Trash Generating Areas

Assessment within San Mateo County  1/3 complete = 59 Centerline miles completed High 1 segment; 1 ramp Medium 59 segments; 9 ramps Low 177 segments; 18 ramps  2/3 underway = 142 miles Route 1 Route 109 Route 114 Route 35 Route 82 Route 84 Route 9 Route 92

Identifying Cooperative Implementation Opportunities within High Trash Generation Areas  Capital funds for Design & Construction of Regional Treatment Controls Compliance with Mandates –TMDLs –Trash Control Control Measures: –Detention Basins –Infiltration Basins –Gross Solids Removal Devices –Media Filters –Biofiltration Swales/Strips –Infiltration Trenches –High Volume Infiltration Devices

CRITERIA - Identifying Cooperative Implementation Opportunities Criteria for Participation in Regional Treatment Control Project:  Reach Prioritization List  Number of Pollutant Categories – TMDLs and Trash  Project Stage – Concept, Project Approval/Env. Doc., Design  Lead Agency  Project Schedule  Capital Costs – Design and Build  Maintenance and Operations Costs  Number of Stakeholders  Amount of Runoff treated from CT Right of Way  Type of BMP  Number of acres treated

Trash Load Reduction Workplan Schedule Next Steps: Complete remaining on-land visual assessments - Target 12/31/15 –520 miles ramps Maps of high trash generation areas and prioritized list of high trash generation areas – Target 12/31/15 Strategy for implementation of control measures - Target 12/31/15 –Within Caltrans right-of-way »Storm drain system retrofits »Enhance institutional measures –Outside Caltrans right-of-way »Partnering with local agencies/Caltrans Cooperative implementation strategy to implement Regional Treatment Controls
