Construction Site Best Management Practices
and the Project Design Process
2
Why are you here

• As 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 engineers estimate of separate
  Construction Site BMPs
• Incorporate a Construction Site BMP strategy into
  the Storm Water Data Report

• To complete these tasks, you also need to know
• About the Standard Special Provisions

Caltrans StatewideNPDES Permit

• Issued in 1999 by the State Water Resources
  Control Board (SWRCB)
• Implements year-round program throughout state to
  control storm water and nonstorm water
  discharges from all Caltrans properties
• Caltrans must comply with the California General
  Construction Permit
• Appropriate best management practices (BMPs) must
  be installed

General Construction Permit

• Applies to projects that disturb gt 1 acre (0.4
  ha) of soil
• Disturbance means any construction activity that
  creates exposed soils
• Applies to smaller areas if part of a larger
  common plan of development
• Requires development of a storm water pollution
  prevention plan (SWPPP)
• Enforced by the RWQCBs

Caltrans SWMP

• The Storm Water Management Plan (SWMP) was
  adopted in May 2003 and includes the following
• How Caltrans is organized
• The responsible people
• The process to disseminate information to staff,
  contractors, and public
• A self-audit program

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 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

NPDES Definitions

• 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

Caltrans-Approved Best Management Practices (BMPs)

• There are several Caltrans-approved BMPs
• Design Pollution Prevention (DPP) BMPs
• Treatment BMPs
• Maintenance BMPs
• Construction Site BMPs

Construction Site BMP Categories
Construction Site BMPs are separated into six BMP
categories as follows

• Soil Stabilization Practices
• Sediment Control Practices
• Tracking Control Practices
• Wind Erosion Controls
• Non-Storm Water Controls
• Waste Management and Materials Pollution Controls

Temporary vs. Permanent BMPs

• Temporary
• Implemented only for the duration of the contract
• Will be removed

• Permanent
• Installed as part of the construction work
• Will not be removed

Active vs. Non-Active Areas
Active Areas are construction areas where soil
disturbing activities have already occurred and
continue to occur or will occur during the
ensuing 21 days.
Non-Active Areas are construction areas (formerly
active areas) that will be idle for at least 21
days.

Okay, I have a couple of questions
What are the benefits of identifying Construction
Site BMPs during the project design process?
What is Department policy concerning Construction
Site BMPs and the project design process?
