• Caltrans Statewide NPDES Permit

• California General Construction Permit

• Caltrans Storm Water Management Plan

Regulatory Background

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.

Types of Erosion

Final Wrap-Up

Sediment is the most common pollutant washed from construction sites. 7

Tracking, Wind Erosion,

and Construction Site Management

Final Wrap-Up

• 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

Questions

Mar/CC 580, Richmond-San Rafael Bridge Seismic Retrofit 20

A few last questions

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?

21

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.

To be or not to be?

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

Remember your efforts will

improve the project delivery process by

24

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
