SEPTEMBER 5, 2015.

Your Role in Scoping1.) When/Why?

- Early in the environmental process to identify issues

and content of the environmental documents

2.) Who?

- The public + federal, state and local agencies

3.) What?

- To identify potential issues of concern, impacts to

be analyzed, and the level of detail in the analysis

4.) How?

- By providing your verbal and written comments

- We encourage you to stay involved, get on our mailing list

and check the project website for updates

Project Location

Alamitos Bridge(53-0064)

Why is the Project Needed

Bridge has seismic deficiencies May fail during earthquake

Substructure (columns) is deficient

Potential scour issues

Erosion of channel banks

Project will enhance structural integrity of bridge and allow it to meet current seismic standards

Project will enhance public safety and maintain traffic flow on PCH

EXISTING CONDITIONSThe existing road and bridge between Loynes Dr. and 2nd street has: North Bound:

two 12-foot lanes a 5-foot bike lane a variable shoulder (3-foot on bridge, variable off bridge) A raised sidewalk

South Bound: three 12-foot lanes a 5-foot bike lane a variable shoulder (3-foot on bridge, variable off bridge) a raised sidewalk

Median: Varies from 4 to 25 feet (4-foot on bridge, variable off)

EXISTING CONDITIONS

Horizontal clearance under the bridge (between bents 11 and 12): minimum 40 feet

Vertical clearance under the bridge (between bents 11 and 12): minimum 16 feet above mean lower low water (the average of the lowest low tides)

Project Alternatives

1) Alternative 1: No Build

2) Alternative 2: Seismic Retrofit (Minimum Build Alternative)

3) Alternative 3: Bridge Replacement Alternative

ALTERNATIVE 1 (No Build)

No improvements will be made The bridge will remain seismically

deficient

ALTERNATIVE 2 (Seismic Retrofit)

ALTERNATIVE 2 (Seismic Retrofit)

Features: Would bring up to current seismic standards

Would add new support columns Would strengthen existing columns Would add new support beams Would strengthen joints between deck slabs Would relocate some utilities

Above deck safety improvements Would upgrade guardrails at each end of the bridge Would add new sidewalk on NB side at each end of the bridge

ALTERNATIVE 3 (Bridge Replacement)

ALTERNATIVE 3 (Bridge Replacement) Features:

Would meet seismic safety standards

Considering 4-span and 5-span options (with different architectural treatments)

This rendering is just an example of what the new bridge could look like

The channel would remain open to boaters during demolition and construction

ALTERNATIVE 3 (Bridge Replacement) Features:

Would be 23 feet wider than existing bridge To allow for standard median and shoulders The adjacent roadway would be widened to match

Would be higher than existing bridge The adjacent roadway (approx. 750 feet each side) would have to be raised

Construction would be done in stages to maintain traffic flow on PCH
