Introduction of Presenters

• Christopher Webb, Project Manager, MN
• Clark Stevens, RoTo Architects
• Mark Carpenter, KTUA Not Present Today

4
Project Understanding

• The Lagoon Water Quality Is Impaired
• Upstream Freshwater Inputs Are Significant
• Lagoon Area Is Constrained
• Habitat Quality Is Compromised
• Lagoon Hydraulics Are Not Optimal
• The Site Is High-Profile (Surfing and Public Use)
• An Opportunity Exists for a Significant
  Ecological and Public Benefit

STAFFING PLAN
7
Approach Plan Formulation

• Identify Opportunities and Constraints
• Plan the Ultimate Project
• Address High Priority, Short-Term Lagoon
  Restoration in Detail
• Focus on Simple, Holistic Solutions
• Design to Facilitate Construction

8
Privately Owned Land-Not Part of Project
(inclusive of B1)
9
Hydrogeomorphics

• Issue
• Pass the Flood
• Improve Circulation
• Anticipate Sediment Delivery

• Solution
• Remove Constrictions
• Design a Functional Lagoon
• Identify Sources, Design for Sedimentation

10
Water Quality

• Issue
• High Temperature and Bacteria Concentration
• Low Dissolved Oxygen
• Grease, Oils, Metals Input
• Septic Leaks
• Poor Nutrient Cycling

• Solution
• Increase Lagoon Volume, Circulate
• Increase Circulation
• Filter All Drainage
• Circulate Water
• Increase Nutrient Uptake

11
Habitat

• Issue
• Degraded Habitat
• Monotypic Habitat
• Establishment of Exotics
• Intrusion From Adjacent Areas

• Solution
• Optimize Physical and Chemical Conditions
• Diversify Brackish Marsh
• Remove Exotics and Install Natives
• Provide Buffering

12
Access and Educational Opportunities

• Issue
• Access not Optimal for Restoration
• Potential Educational Opportunities not yet
  Realized
• Public Interface not yet Optimized

• Solution
• Modify Access According to Restoration
  Alternatives
• Plan Educational Opportunities to Realize the
  Sites Potential
• Design Public Interface System to Maximize
  Benefits, Reduce Impacts

14
Alternatives Development

• Range From Least to Greatest Modifications
• Increase Circulation and Minimal Lagoon Change
• Increase Circulation With Major Lagoon
  Modification South of PCH
• Increase Circulation With Improvements Both South
  and North of PCH as Appropriate and/or
• A Combination of These Options

15
Maintenance and Monitoring

• Create a Self-Sustaining System by Employing
  Simple, Long-Lasting Solutions
• Monitor Water Quality (DO, Temperature, Bacteria,
  Nutrients), Hydraulics, Sedimentation, Habitat
• Maintain by Circulating, Removing Exotics,
  Clearing Stormwater Filters, Repairing Access
  Trails

Project Benefits to Heal the Bay

• Successful Restoration of High Profile
  Restoration Project That
• Improves Water Quality
• Does Not Affect Existing High Quality Surfing
  Resources
• Results From Consensus-Building With Stakeholder
  Groups
• Depth of Resources to Apply to the Challenge
• Collaboration With Agencies
