Tijuana Estuary Tidal Restoration Project TETRP Sedimentation Flooding

Tijuana Estuary Tidal Restoration Project - TETRP

Sedimentation & Flooding of Goat Canyon ~ 2000

Tijuana Estuary Tidal Restoration Program (TETRP) Goal 1. Increase tidal prism. Goal 2. Restore former salt marsh, tidal channel, and mudflat to the maximum extent possible. Goal 3. Increase area of undisturbed transition zone. Goal 4. Restore barrier beach and dunes. Goal 5. Increase habitat for endangered species. Approved EIR / EIS 1992 Goal 6. Incorporate research and adaptive management.

. Adaptive Restoration Milestones 1991: TETRP EIR/EIS 1997: Tidal Linkage 2000: Model Marsh 2005: Goat Canyon Enhancement Plan 2008: TETRP II - Feasibility Study 2016: TETRP II - Phase I • • Start small and apply lessons learned to future projects Incorporate research and monitoring

TIDAL LINKAGE 2. 25 ACRES 1996 -1997 Created tidal creek and marsh habitat, and increased circulation into former sewage ponds • Plant palettes (don’t plant Salicornia pacifica) • Soil amendments • Protection from herbivory • Construction challenges (volumes of soil moved)

MODEL MARSH 20 ACRES 1999 -2000 Restored tidal marsh buried by sedimentation from Mexico • Planting strategies for Spartina foliosa • Development of creek networks in experimental cells
