Why are you

hereWhy are you

hereAs Caltrans staff from Design (or other divisions) you need to know how to

• Assess your project for implementation of appropriate Construction Site BMPs

• Incorporate selected Construction Site BMPs as separate bid items (lump sum is not an option)

• Develop the engineer’s estimate of separate Construction Site BMPs

• Incorporate a Construction Site BMP strategy into the Storm Water Data Report

Department Policy

Department Policy

• The storm water data report should describe the strategy for incorporating construction site BMPs into the contract documents.

• Designers are required to consider the BMPs as separate bid line items for all projects.

• Preferred types of BMPs may vary from district to district; therefore, Design and Construction Divisions should be in concurrence with the strategy.

Department GoalsDepartment Goals

Better projects can be achieved 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

What is a “best management practice (BMP)”

• A measure implemented to protect water quality and reduce potential pollutants associated with storm water runoff

• Any program, technology, process, siting criteria, operating method, or device that controls, prevents, removes, or reduces pollution
