*CEQA: California Environmental Quality Act
*IS/MND: Initial Study/Mitigated Negative Declaration
Background
• Bridge Preventive Maintenance Project (BPMP)
• Three bridges:
• Canyon Road Bridge
• Spruce Road Bridge
• Marin Road Bridge
• In 2012 it was determined all three bridges required
maintenance
• The overall goal is to maintain these bridges to extend their useful life
Canyon Road Bridge
• Replacing one
wingwall and
repair another
• Sealing the cracks
in the bridge deck
• Minor repairs to
fish ladder
Spruce Road Bridge
• Seal the deck
• Repair the
expansion joints
• Repair structural
concrete spalls
on the underside
of the bridge
Marin Road Bridge
• Repair a wingwall and
the rock slope
protection around it
• Repair structural
damage to another
wingwall
• Repair concrete spalls
on the underside of the
bridge

Initial Study (IS)
Mitigated Negative
Declaration (MND)
BPMP may result in
impacts on the
environment, but we can
mitigate those impacts

Environmental Impacts from BPMP
• Air Quality, Biological Resources, Cultural
Resources, Geology and Soils, Hydrology and Water
Quality, Noise, and Tribal Cultural Resources.
• IS/MND concluded that all environmental impacts
can be mitigated to less-than-significant levels.
• IS/MND includes a Mitigation Monitoring and
Reporting Program to ensure environmental
impacts are mitigated during construction
Public Review Process
• Draft IS/MND was circulated for a 30-day public review period January 16 – February 16
• Letters were sent to residents who are most impacted by the project and notice was advertised in the Marin IJ
• Two letters with comments were received relating to
Canyon Bridge. The Final IS/MND includes responses to
these comments and no significant changes to the
project occurred based on the comments.
Closing
• Conclusion:
• All potentially significant impacts can be mitigated to a less- than-significant level. • There is no substantial evidence that the project will result in significant environmental impacts with mitigation in place.
• Recommendation:
• Adopt the IS/MND and Mitigation Monitoring and Reporting Program (MMRP)
• Approve the project
