comprehensive and it is exciting to see this
data finally compiled. My comments reflect 70 82%
what I liked most about this station.
Interesting! This station’s information is
excellent, but there are a couple
shortcomings that could be investigated 13 15%
further. My comments express the data gaps
that I observed.
Unimpressed! The information displayed at
this station is not complete and there remain
noticeable opportunities for growth. In my 2 2%
comments I have described the areas that
could be improved upon.

12. Los Cerritos Wetlands Authority
In February of 2006, a joint powers agreement was
adopted among the:
Rivers & Mountains Conservancy, State Coastal Conservancy,
& Cities of Long Beach & Seal Beach
=
These agencies comprise the project’s Steering Committee

13. Natural History of Los Cerritos Wetlands

14. Los Cerritos Wetlands
Exisiting Conditions
• Historically over 2400 acres of coastal wetlands
• Currently around 500 undeveloped acres remain
– Only ~50 acres of full tidal coastal salt marsh habitat
– Highly degraded upland, marine, transition, brackish & salt
marsh habitats
– Large invasive exotic weed infestations
– Impacted by industrial, commercial & residential land
uses
– Serves as refuge for migratory & special status species

16. Project Scope
• Develop conceptual restoration plan for Los Cerritos Wetlands
• 2 year long project
• 6 public involvement workshops through Spring 2013
• 6 meetings with the project’s Technical Advisory Committee

18. Conceptual Restoration Alterative Design Process
• Collect data on existing conditions
• Compile and analyze opportunities and constraints to
restoration
• Meet with the Public to brainstorm potential restoration
alternatives
• Determine preliminary restoration alternatives
• Meet with Technical Advisory Committee and Public to
identify final alternatives
• Analyze each of the final restoration alternatives
• Work with all stakeholders to determine the preferred
restoration alternative

19. Opportunities
• Topography / Landforms / Soils
– Existing ground elevations suitable for coastal wetlands
– Existing landforms can be used to control water
– Existing roads can provide high tide refugia
– Soils suitable for wetlands and uplands habitat cover
– Site location provides opportunities for soil disposal
– Site size provides opportunities for onsite remediation
– Presence of earthquake fault may be deterrent to other development
• Tidal Exchange / Local Watersheds / Hydrology
– Site Location Provides Tidal Exchange Enhancement Opportunities
– Site Location Provides Freshwater Enhancement Opportunities
– Altered Geomorphology Minimizes Sedimentation-Related Maintenance
– Watershed Activities will Provide Improved Water Quality

20. Opportunities (cont.)
• Ecology
– Already Existing Ecologically-Valuable Areas
– Habitat Potential for Degraded Land Areas
– Already Existing Special Status Species
– Adjacency to Wildlife Corridors and Connectedness
– Potential for Freshwater Habitat
– Conversion of Upland Areas to Wetlands Habitat Area
• Climate Change
– Utilization of Sea Level Rise (SLR) for Tidal Influence
– Existing Hellman Topography Provides for Habitat Adjustment
– Potential to Restore Natural Sedimentation
– Potential to Accommodate Upslope Transgression of Habitats
– Potential to Increase Flood Protection

21. Opportunities (cont.)
• Infrastructure
– Lease Agreements Include Reconfiguration of Oil Infrastructure
– LCWA-Owned Property Includes the San Gabriel River Levees
• Human Interaction
– Public Access to Large Open Space Area
– Synergy with LCW Stewardship Program
– Active Local Stakeholders
– Cooperative Efforts with Local University
– Adjacent Existing Public Use Areas
– Limited Visibility from Housing Developments
– Already Existing Infrastructure for Public Interpretation
• Regulatory / Implementation
– Potential for Additional Land Acquisition
– Potential Funding Opportunities
– Potential for Agency Coordination

22. Constraints
• Topography / Landforms / Soils
– Historical Land Uses have Altered Natural Topography
– Landform Changes Limit Natural Processes
– Existing Soil Quality Limits Restoration Success
– Earthquake Fault may Constrain Oil Infrastructure Reconfiguration
and/or Cause Damage to the Wetlands
• Tidal Exchange / Local Watersheds / Hydrology
– Human Disturbance has Altered Tidal Exchange
– Human Disturbance has Altered Freshwater Hydrologic Functioning
– Human Disturbance has Altered Geomorphology
– Poor Water Quality can Impair Restoration Success

23. Constraints (cont.)
• Ecology
– Protection of Existing Sensitive Habitat Resources
– Simplified Food Webs
• Climate Change
– SLR will Modify Habitat Proportions
– Steep Perimeters will Only Support Narrow Habitat Bands
– Natural Sediment Supply is Limited
– Limited Areas for Upslope Transgression of Habitats
– SLR and Flooding Risk
• Infrastructure
– Incorporation of Existing and Future-Remaining Oil Infrastructure
– Fragmentation and Encroachment by Roadways
– Protection of Existing Flood Control Systems
– Fragmentation and Encroachment by Utilities

24. Constraints (cont.)
• Human Interaction
– Habitat Sensitivity to Urban Surroundings
– Onsite Homeless Encampments
– Maintaining Positive Public Perception
– Potential Impacts to Surrounding Neighborhoods
– Archaeological Resource Protection
• Regulatory / Implementation
– Land Ownership by Other Entities
– Easements by Other Entities
– Limited Funding
– Compensatory Mitigation Restrictions
– Permitting and Environmental Reviews
– Compliance with the City of Long Beach Local Coastal Program
and General Plan

25. Workshop Activity
Now we want to work on developing preliminary concepts for
restoration alternatives with you
We encourage you to use the maps in front of you and:
5. Use the Green Marker to outline areas you think need
Lots of Restoration Attention
6. Use the Blue Marker to outline areas you think need
Less Restoration Attention
7.Use the Red Marker to outline areas you think need
Little Restoration Attention
Use the pens on the table to explain the
“bubbles” you have created and describe
what your vision is.
