City of Encinitas Sea Level Rise Workshop

Climate Action Plan May 8, 2018

Crystal Najera, CAP Program Administrator 1 PRESENTATION OVERVIEW

How does the City’s Climate Action Plan address Sea Level Rise?

2 Global Climate Change

3 GLOBAL CLIMATE CHANGE

4 GLOBAL CLIMATE CHANGE

Industrial activities have raised global atmospheric carbon dioxide levels from 280 parts per million to 400 parts per million in the last 150 years.

5 GLOBAL CLIMATE CHANGE

Temperatures will More droughts and continue to rise heat waves

The frost-free season (growing season) will Sea level will rise lengthen 1-4 feet by 2100

Change in precipitation Hurricanes will become patterns stronger and more intense

Potential Sea-Level Rise Impacts to City Infrastructure - 2050 to 2100 Impact Sector Vulnerability Areas  Beach and Public Access  Cardiff Reef State Beach and Seaside State Beach  Public Access Staircases Buildings  Swami’s Beach Lifeguard Tower  Storm water infrastructure near San Elijo Lagoon and Moonlight Beach Storm Drains  Storm drain inlets and outlets near coastal bluffs  Cardiff Sewer Pump Station*  Infrastructure surrounding San Elijo Lagoon Wastewater  Infrastructure at Moonlight Beach*  Two lift stations in  Increased potential for sewer spills Drinking Water  Aboveground infrastructure near San Elijo Lagoon  Highway 101 near San Elijo Lagoon Transportation  Coast Highway 101 south of the Self-Realization Fellowship Temple Biodiversity and Habitat  Eighty-six sensitive species within the coastal area  Impacts to tourism Social Sector  Economic impacts Source: San Diego Regional Coastal Resilience Assessment Draft Report (2017) Notes: *upgraded to address sea level rise 15 Climate Adaptation

16 CLIMATE ADAPTATION

What is Climate Adaptation?

The process of identifying the potential vulnerabilities to climate change and addressing those impacts through strategic planning.

California Adaptation Planning Guide

Phase 1: Assessment of Vulnerabilities Phase 2: Development of Adaptation Strategies

17 CLIMATE ADAPTATION

Adaptation Strategies in the Climate Action Plan

• Prepare for Increase in Temperatures and Extreme Heat • Prepare for Changes in Precipitation Patterns and Water Supply • Prepare for Increased Wildfire Risk • Prepare for Increase Flood Risk • Prepare for Sea Level Rise

18 SEA LEVEL RISE ADAPTATION

Strategy 1: Continue to study and plan for Sea Level Rise

• Sea Level Rise Adaptation Strategy for San Diego (ICLEI, 2012) • Multi-jurisdictional Hazard Mitigation Plan (San Diego County, 2010) • Regional Economic Vulnerability to Sea Level Rise In San Diego County (Center for the Blue Economy, 2018) • General Plan Safety Element update • Coastal Vulnerability and Resiliency Plan

19 SEA LEVEL RISE ADAPTATION

Strategy 2: Develop a Coastal Vulnerability and Resiliency Plan

• Consistent with: – Multi-jurisdictional Hazard Mitigation Plan – Federal Emergency Management Agency (FEMA) Hazus mapping

20 SEA LEVEL RISE ADAPTATION

Strategy 3: Develop a comprehensive outreach strategy

– Stakeholder input – Community education

21 SEA LEVEL RISE ADAPTATION

Strategy 4: Continue beach nourishment, coastal bluff management and wetland restoration

Recent Coastal Projects: – US Army Corps of Engineers 50-year Beach Nourishment Project – Encinitas Opportunistic Beach Fill Program – SANDAG Regional Beach Sand Projected I & II – Batiquitos Lagoon Dredging – San Elijo Lagoon Restoration Project – Cardiff Beach Living Shoreline Project (begins Sept 2018) 22

SEA LEVEL RISE ADAPTATION

Strategy 5: Coordinate with relevant regional and national agencies

23 SEA LEVEL RISE ADAPTATION

Strategy 6: Map critical infrastructure and plan for Sea Level Rise

Recent City Infrastructure Projects: – Marine Safety Center at Moonlight Beach – Third and B St Sewer Pump Station Upgrades – Sewer Pump Station Redesign – I-5 and Manchester Sewer Pump Station Redesign
