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.

• Protect DSAs from erosion• Minimize sediment in storm water
before discharge• Control discharges of sediment
from other sources• Prevent non–storm water

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
