The Erosion Crisis

Hawaiʻi’s Beaches Are Disappearing

70% of beaches on Kauaʻi, Oʻahu, and Maui are actively eroding. With sea-level rise accelerating, over 90% of some shorelines face chronic retreat within decades.

Our Methodology

Geomorphic Science, Nature-Based Design

Every shoreline is a dynamic system shaped by waves, currents, sediment supply, and geology. Our approach starts with understanding these processes at a granular level, then designing interventions that harness natural forces rather than fighting them.

01

Process-Based Analysis

We map sediment budgets, wave energy regimes, and littoral transport pathways using field surveys and historical data to build a complete picture of how each shoreline behaves.

02

Geomorphic Modeling

Our team develops shoreline change models incorporating sea-level rise projections, seasonal wave patterns, and sediment dynamics to forecast future conditions at each site.

03

Nature-Based Design

We design dune systems, beach nourishment plans, and living shoreline strategies calibrated to site-specific conditions. Solutions that build resilience while preserving beach access and ecology.

What We Do

Services

From initial scientific assessment through design and adaptive management, we provide the technical expertise to guide your shoreline project from concept to long-term success.

Shoreline Erosion Assessments

Detailed geomorphic site evaluations including historical shoreline analysis, sediment characterization, wave exposure mapping, and quantitative erosion rate projections under multiple sea-level rise scenarios.

Beach Nourishment & Dune Design

Science-based design of nourishment projects and engineered dune systems, including sediment source analysis, volume calculations, grain-size compatibility studies, and native vegetation planting schemes.

Regulatory & Permitting Guidance

We help clients navigate Hawai’i’s complex multi-jurisdictional permitting landscape (DLNR, CZM, Army Corps, county SMA) with technically robust applications that align with state policy favoring nature-based solutions.

Long-Term Monitoring & Adaptive Management

Ongoing survey programs with photo documentation, beach profile measurements, and annual reporting. Our adaptive management frameworks include pre-determined triggers for maintenance or design adjustments.

Who We Are

Deep Expertise, Local Partnerships

Our team is led by an experienced coastal geomorphologist with extensive shoreline restoration work across the Pacific Northwest. We bring rigorous scientific methodology honed through years of complex, multi-stakeholder projects in Washington State.

In Hawai’i, we focus on what we do best: the science, analysis, and design. For on-the-ground implementation, we partner with trusted local contractors, cultural practitioners, and community organizations who understand the land, the water, and the people.

This model ensures every project benefits from both cutting-edge geomorphic science and deep local knowledge.
