Chapter 6C — Temporary Traffic Control Elements November 7, 2014
Part 6 — Temporary Traffic Control
In the Santa Clara Valley, storm drains flow
directly to our local creeks, and on to San
Francisco Bay, with no treatment.
Storm water pollution is a serious problem for
wildlife dependent on our waterways and for
the people who live near polluted streams or
baylands.
Proper management of construction sites
reduces pollution significantly.
This sheet summarizes the "Best Management
Practices" (BMPs) for storm water pollution
prevention.

Storm Drain Pollution
from Landscaping and
Swimming Pool Maintenance
Many landscaping activities expose soils and
increase the likelihood that earth and garden
them cats will run off into the storm drains during
irriga ton or when it rains
Swimming pool water contairing chbnne and
copper -based algaecides should never be
discharged to storm drabs. Those chemicals are
toxic to aquatic life.

Earth -Moving
Activities
Storm Drain Pollution
from Earth -Moving Activities
Soil excavation and grading operations loosen large
amounts of soil that can flow or blow into storm
crams when handled improperly. Sediments in runoff
can clog storm drains smother aquatic life. and
cestroy habitats in creeks and the Bay. Effective
erosion control practices reduce the amount of runoff
crossing a site and slow the flow with check dams or
roughened ground surfaces
Practices During Construction
J Remove existing vegetation only when
absolutely necessary Plant temporary
vegetation for erosion control on slopes or
where construction is not immediately planned.
Protect downslope drainage courses,
streams, and storm drains with wattles, or
temporary drainage swales Use check dams or
ditches to divert runoff around excavations.
Refer to the Regional Water Quality Control
Board's Erosion and Sediment Control Field
Manual for proper erosion and sediment control
measures
J Cover stockpiles and excavated soil with
secured tarps or plastic sheeting
The property owner and the contractor share ultimate responsibility for
the activities that occur on a construction site. You may be held responsible
for any environmental damage caused by your subcontractors or employees.
