Coastal Hazard Analysis

Sea Level Rise and Coastal Hazard Analysis

We provide coastal engineering evaluations to help property owners, design teams, marinas, and agencies understand sea level rise, coastal flooding, wave run-up, bluff erosion, shoreline hazards, and long-term coastal resiliency needs throughout Southern California.

Sea Level Rise Planning for Waterfront Infrastructure

Sea level rise is an important consideration for coastal infrastructure, waterfront development, shoreline protection systems, and long-term adaptation planning. Rising ocean levels can increase exposure to tidal flooding, storm surge, wave overtopping, erosion, and damage to existing coastal improvements.

We evaluate how projected sea level rise may affect seawalls, bulkheads, revetments, floating docks, piers, cantilevered decks, coastal foundations, and shoreline access improvements. These evaluations can support California Coastal Commission review, local permitting, maintenance planning, and coastal resiliency decisions.

Coastal Hazard Analysis

Coastal hazard analysis helps identify risks associated with changing shoreline conditions and extreme coastal events. Southern California coastal properties may be affected by combined hazards including storm waves, high tides, erosion, coastal cliff retreat, bluff instability, and wave run-up.

Coastal Cliffs, Bluffs and Shoreline Protection

Coastal cliffs and bluffs require careful evaluation because erosion, wave attack, groundwater, drainage, and slope instability can affect both private improvements and public coastal resources. Hazard analysis may be used to evaluate shoreline setback considerations, protection alternatives, and long-term performance of coastal structures.

Our work supports projects in Malibu, Santa Monica, Long Beach, Huntington Beach, Newport Beach, Laguna Beach, Dana Point, Santa Barbara, and coastal Southern California communities exposed to coastal hazards.

California Coastal Commission Submittal Support

Sea level rise and coastal hazard documentation is often needed for coastal development permit applications, shoreline protection projects, waterfront repairs, maintenance programs, new development, and adaptation planning. We provide engineering narratives, hazard summaries, and technical documentation that can be incorporated into California Coastal Commission and local jurisdiction submittals.

Our evaluations are intended to support informed decisions regarding coastal resilience, flood risk, structural maintenance, repair, rehabilitation, and future adaptation strategies while considering coastal resources, public access, water quality, and long-term shoreline performance.
