Review what we’ve discussed today Take the Post-Test Answer any remaining questions Module V Objectives 2
Final Wrap-Up • Caltrans Statewide NPDES Permit• California General Construction Permit• Caltrans Storm Water Management Plan Regulatory Background 3
Final Wrap-Up Department Policy • The SWDR is to describe the strategy for including Construction Site BMPs into the contract documents. • Must consider the BMPs as separate bid line items for all projects. • Design and Construction Divisions must concur with the strategy. 4
Final Wrap-Up Caltrans-Approved Best Management Practices (BMPs) • Design Pollution Prevention BMPs • Treatment BMPs • Maintenance BMPs • Construction Site BMPs 5
Final Wrap-Up Caltrans Storm Water Quality Manuals 6
Final Wrap-Up Types of Erosion • Splash erosion • Sheet erosion • Rill erosion • Gully erosion • Channel erosion Sediment is the most common pollutant washed from construction sites. 7
Final Wrap-Up Tracking, Wind Erosion, and Construction Site Management 8
Final Wrap-Up Water Pollution Control Strategies during Construction • Prevent storm water contact with disturbed soil areas (DSAs) • Protect DSAs from erosion • Minimize sediment in storm water before discharge • Control discharges of sediment from other sources • Prevent non–storm water discharges • Prevent storm water contact with other potential construction site pollutants 9
Final Wrap-Up Figures and Tables Minimum effective combination of soil stabilization and sediment controls 10
Final Wrap-Up Selection Process of Construction Site BMPs Start with the Construction Site BMPs Consideration Form 11
Use of Checklist CS-1, Parts 1 - 6 3 27.1 ac 17.3 ac 7.4 ac 2.5 ac 12.4 ac 12
Proposed Construction Site BMPs Deployment Plans (D-Plans) Example Project 14
Final Wrap-Up Standard Special Provisions for Construction Site BMPs • Scheduling • ESA Protection • Soil Stabilization • Slope Interrupter Devices • Concentrated Flow Devices • Sediment Control • Tracking Control • Wind Erosion Control • Concrete Washouts • Construction Site Management Designate separate bid lineitems for appropriate BMPs. 15
Final Wrap-Up Standard Special Provisions for Construction Site BMPs • SSP 07-340 WPCP Preparation Requirements • SSP 07-345 SWPPP Preparation Requirements • SSP S5-630 Relations with the RWQCB • SSP 07-346 Construction Site Management 16
Final Wrap-Up Finalize PS&E Package for Construction Site BMPs • Include Water Pollution Control quantity sheets • Include special provisions of selected bid line items • Include details of selected bid line items • Provide estimated quantities for selected bid line items • Provide estimated costs for selected bid line items 17
Final Wrap-Up Include Construction Site BMP Strategy in the Storm Water Data Report • At each design phase (PID, PA/ED, PS&E), include the following: • Temporary BMP selected • Quantity and cost information • Construction Division concurrence information 18
Course Summary • You now should be able to • Select appropriate Construction Site BMPs • Incorporate Construction Site BMPs • Estimate quantities and costs for Construction Site BMPs • Incorporate a Construction Site BMP strategy into the Storm Water Data Report 19
Questions 20 Mar/CC 580, Richmond-San Rafael Bridge Seismic Retrofit
A few last questions To be or not to be? The Construction Site BMPs Consideration Form must be initialed and included in the Storm Water Data Report at all phases of design. True or False? Are rainfall intensity curves and average yearly rain days needed for the designer to select the appropriate soil stabilization and sediment controls? Name the three elements of the Construction Site BMPs strategy. 21
The Post-Test • Repeats the test given at the beginning of the course • Has a time limit of 15 minutes • Covers course topics • Evaluates what you have learned • Helps evaluate the effectiveness of this training 22
Post-Test 23
Remember your efforts will improve the project delivery process by • Helping contractors develop more accurate, competitive bids for all Caltrans construction projects • Reducing construction costs arising from contract change orders (CCOs) and claims • Facilitating implementation of preferred temporary BMPs during construction of the project 24
