STATE ROUTE 1 ALAMITOS BAY BRIDGE IMPROVEMENT PROJECT SCOPING MEETING AUGUST 5, :00 p.m.Open House 6:30 p.m.Presentation 7:00 p.m.Public Comment 7:30 p.m.Resume Open House/Q&A

Purpose of Scoping:  To identify issues to be addressed in the environmental documents Lead Agencies:  CEQA: Caltrans is the state lead agency  NEPA: Caltrans is the delegated federal lead agency Written comments:  Please submit comments by SEPTEMBER 5, 2015.

Your Role in Scoping 1.) 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 ( )

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 CONDITIONS The existing road and bridge between Loynes Dr. and 2 nd 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)

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)

 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

We Want to Hear From You  Accepting written comments (via postal mail)and oral comments at this meeting  Comment period ends September 5, 2015  Comments will be summarized in the Scoping Summary Report
