DRAFT April 2025
In February 2025, The Nature Conservancy (TNC) and The University of Hawaiʻi Community Design Center (UHCDC) conducted an initial series engagement events as part of a broader initiative to explore nature-based solutions for coastal resilience. The project team met with stakeholders and community members to listen, gather feedback, and understand priorities and concerns regarding the project area.
This phase of engagement consisted of three meetings: one in-person event at the Lahaina Intermediate School cafeteria in Lahaina, HI, followed by two virtual sessions on Zoom, with a combined total of 92 participants. The primary focus of these events was to introduce the project and gather ideas and knowledge from the community.
In addition to preparing and guiding engagement activities, UHCDC created educational materials focused on the importance of coral reefs, nature-based solutions, traditional ecological knowledge, and sea-level rise effects and adaptation. These resources were integrated into the sessions to provide context and support informed discussions.
This report chapter summarizes event materials, interactive exercises, and outcomes. Insights gathered from the initial community engagement phase will shape the preliminary visioning and conceptual design development, ultimately aiming to create a framework for a more resilient and sustainable Olowalu-Ukumehame coastline and reef system.
Event dates:
February 6, 2025, 5:30 - 7:30 PM (Lahaina Intermediate School) - 55 participants
February 11, 2025, 12:00 - 1:30 PM (Zoom) - 27 participants

In 2017, West Maui’s Olowalu reef was declared a Mission Blue Hope Spot—a place that is critical to the health of our oceans. Spanning the coast from Olowalu to Pāpalaua, the 939-acre reef boasts a stunning diversity of coral, harbors the largest known manta ray population in the United States, and is a primary source of coral larvae for the reefs of Lāna’i, Moloka’i, and West Maui.
Coral Reef Benefits
Protect Coasts
Coral reefs block up to 97% of the wave energy hitting our coastlines.
Prevent Flooding
Reefs provide flood protection to people, property, and jobs valued at more than $836 million each year.
Sustain Fisheries
Hawai’i’s reefs support nearshore fisheries worth $13.4 million each year.
Support Livelihoods
Coral reefs contribute more than $1.2 billion through reef-related tourism to the state’s economy.
Connect Us to Cultural Heritage
Hawai’i’s reefs connect us to our islands’ natural and cultural heritage.

Nature-Based and Living Systems
Soft blue-green infrastructure that supports ecosystem services, increases the distance between water and the built environment, retains and absorbs inundation, attenuates waves, slows erosion, provides habitat, and contributes to biodiversity. Examples: wetlands, tidal marshes, and other living coastal buffers.
Managed Retreat (Relocation)
Long-term relocation or removal of existing buildings, infrastructure, and resources out of hazard areas to higher elevations and limited construction of new development in vulnerable areas. Planned withdrawal from the shoreline and/or low-lying zones over time through strategic relocation. Example: Honoapiʻilani Hwy re-alignment.
Hardened Shoreline Protection
Hard, engineered, linear infrastructure systems designed to defend, armor, and stabilize the shoreline and resources in their current location. Examples: impermeable structures, seawalls, levees, dikes, revetments, groins, breakwaters, riprap, dams, flood gates, storm surge barriers, etc.
Floodable Structures and Landscapes
Structures and landscapes designed to withstand and function during inundation events. Accommodating habitable space, critical assets, and vulnerable infrastructure on upper levels or at higher elevations decreases hazard risks and increases resilience to the impacts of sea level rise and flooding.
Elevated Structures and Landscapes
Accommodating in place by raising the height of land, infrastructure, buildings, and other resources for existing or new development over time to safer elevations using fill and/or pilings with the goal of decreasing hazard risks and increasing resilience to the impacts of sea level rise and flooding.
Floating Structures and Landscapes
Accommodating and adapting in place by floating buildings, transportation elements, and infrastructure designed with fluctuating and rising water levels in mind has the potential to increase resilience to the impacts of sea level rise and flooding. Structures are fastened to the coast or bottom of water with flexible connections.
In-Person and Virtual Engagement Event Results (2/6/25, 2/11/25, 2/13/25)
What is the first word that comes to mind when you think of the current Honoapi’ilani Highway?
At the start of the in-person engagement event, participants were invited to respond to an entry question displayed on a whiteboard: “What is the first word that comes to mind when you think of the current Honoapiʻilani Highway?” This prompt encouraged community members to share their immediate thoughts and perceptions, setting the tone for the discussions ahead.
As participants entered the cafeteria, they wrote their responses directly on the whiteboard, creating a collective reflection of public sentiment. The words varied widely, capturing both concerns and observations, from traffic and erosion to access and resilience.
During the two virtual events, participants engaged with the same question through Mentimeter, a digital interactive tool that allowed them to contribute responses in real time.
The resulting word cloud visually summarizes the responses from both in-person and virtual events. In the graphic, larger words indicate more frequent mentions, illustrating key themes. Participant responses highlighted the vulnerabilities and challenges of the existing Honoapiʻilani Highway while also acknowledging the surrounding area’s natural beauty and significance.
Top responses from participants were:
• Traffic (8)
• Erosion (7)
• Sea-level rise (5)
• Wet (3)
• Flooding (3)
• Scenic (3)
Categories Green: Natural features and recreation
Orange/yellow: Road-related hazards and problems
Blue: Climate-related vulnerabilities
Local knowledge from residents and community members is essential in developing a conceptual design that prioritizes both coastal resilience and the well-being of the community. The first interactive exercise encouraged participants to share their insight and expertise about the existing project area.
A large-format (14 ft x 5.5 ft), high-resolution aerial map, printed on vinyl, depicted current conditions along the Olowalu-Ukumehame coastline, with key locations, place names, and the proposed highway realignment highlighted. The project team invited participants to engage with the TalkStory Map by leaving comments via color-coded sticky notes in response to four prompts:
Your favorite place and why
Your go-to outdoor activity
Opportunities for future public space
Places you avoid and why
Participants could contribute multiple notes for each category, enabling a wide range of perspectives and insights. For the two virtual community and stakeholder engagement events, the project team prepared a digital whiteboard version of the talk-story map. Participants could either leave virtual sticky notes themselves, speak during the Zoom meetings, or leave written comments in the meeting chat room for UHCDC staff members to transcribe and post on the digital board. This process ultimately revealed how residents and stakeholders currently interact with the coastal environment and highlighted locations of cultural and personal significance.

Heat map analysis of comments left during in-person and virtual engagement sessions indicates the importance of the coastline. Opportunities identified are located throughout the project area, with an emphasis along the existing Honoapiʻilani Highway.
Effective coastal visioning must consider entire watersheds, as conditions in upper elevations directly impact the coastal environment. The second interactive exercise focused on collecting feedback at the scale of the Ukumehame, Olowalu, and Launiupoko ahupuaʻa, emphasizing the interconnectedness of upland and low-lying ecosystems.
To facilitate this discussion, the UHCDC project team fabricated a 4’ x 4’ 3D physical topography model, providing a scaled representation of the region’s geography. The model highlighted key features that included streams, mountain peaks, mile markers, the current Honoapiʻilani Highway, and culturally significant place names.
Alongside the model, two supplementary components provided cultural and ecological context:
• A map of Hawaiian Place Names (Wahi Pana) within the project area, illustrating historically and culturally important sites.
• A draft of TNC’s Ahupua‘a Snapshot, offering a mauka to makai assessment of environmental conditions, land use, and key ecological features within the Olowalu-Ukumehame ahupua‘a.
The project team asked participants to identify places in the model where they saw opportunities for cultural, ecological, or hydrological improvements and encouraged them to leave written comments, elaborating on specific opportunities. Additionally, community members and stakeholders were given the opportunity to label any unidentified locations that were not already pinpointed on the model and leave sticky notes with comments and feedback.
The community’s engagement with the model broadly highlighted the importance of restoring cultural, ecological, and hydrological aspects, particularly focusing on vegetation, while emphasizing the need for resilience along stream corridors and coastal zones.

Accompanying Materials (In-Person and Virtual Engagement Events)
We would greatly appreciate your input and help in further identifying and honoring proper Hawaiian place names within the ahupuaʻa of Launiupoko, Olowalu, and Ukumehame. Traditional place names often reflect natural resources, topography, other landscape features, weather phenomena, and stories, all of which play important roles in envisioning, planning, and designing culturally and ecologically sustainable and resilient environments.
The accompanying materials played a crucial role in enhancing participant engagement and providing cultural and ecological context to the discussion. The Wahi Pana Map helped ground the conversation in historical and cultural knowledge by showcasing traditional Hawaiian place names and their significance within the Launiupoko, Olowalu, and Ukumehame ahupua‘a.
This resource emphasized how place names often reflect natural resources, topography, and local stories, all of which contribute to planning more culturally and ecologically sustainable interventions.
Ridge-to-reef model and accompanying materials
Additionally, The Nature Conservancy’s Ahupua‘a Snapshot--result of earlier community engagement efforts--provided a mauka to makai (mountains to sea) assessment of environmental conditions and key features within the study area. The draft version of this resource outlined critical threats such as erosion, flooding, habitat degradation, and sea level rise, while also identifying opportunities for ecological restoration, conservation efforts, and community-driven stewardship.
This visual representation helped participants understand the interconnectedness of upland and coastal systems and consider potential solutions from a watershed-scale perspective.

In-Person and Virtual Engagement Event Results (2/6/25, 2/11/25, 2/13/25)
The Ridge-to-Reef Model exercise captured key community priorities across the Ukumehame, Olowalu, and Launiupoko ahupua‘a, with a total of 102 pins placed.
The large number of vegetation-related pins highlights a strong focus on native plant restoration, erosion control, and watershed health, while water-related pins emphasize concerns about stream flow, freshwater quality, and impacts of sediment on the Olowalu Reef. The cultural pins reflect a commitment to preserving significant sites and improving access, reinforcing the value of traditional ecological knowledge (TEK) in resilience planning.
Sustainable Agriculture and Land Management:
Use goats to reduce fire risk, remove invasive trees, and plant native/edible vegetation along the highway. Expand tree planting (mauka to makai).
Ecosystem and Habitat Restoration:
Restore native habitats, wetlands, and reefs by replanting vegetation and cleaning up pollution. Remove seawalls and restore dunes to support coastal health.
Tourism and Recreation Management:
Protect Olowalu and Puʻu Kilea from over-tourism, limit upslope recreation for habitat recovery, maintain surf access with proper infrastructure, and establish resident-only campgrounds.
Infrastructure and Community Concerns:
Address homelessness through enforcement and support services.
Add goats to the dry grassy areas - prevent fires

RIDGE-TO-REEF MODEL
Synthesis of In-Person and Virtual Event Results
Results of the Ridge-to-Reef Model engagement activity (in-person and virtual events combined) highlight community member and stakeholder priorities and themes at the ahupua’a scale.
Opportunity locations marked by workshop attendees are concentrated along stream corridors and coastal zones. The majority of pins placed by participants focused on ecological opportunities, particularly vegetation (51 pins), water (34 pins), and cultural (17 pins).
Key themes that emerged include protecting mauka areas and streams, native forest rehabilitation, wetland restoration, pollution cleanup, and preserving the mauka-to-makai relationship. These priorities emphasize the community’s focus on restoring natural ecosystems, improving water quality, and strengthening watershed resilience.

This interactive mapping exercise engaged stakeholders in a timeline-based coastal visioning activity, designed to explore how historic land uses within the project area have shaped the presentday landscape and to identify future opportunities for resilience. The activity was structured around three maps, each illustrating a different time period: pre-Western contact, plantation era, and future conditions.
The project team asked participants to place pins and provide written comments on the maps to share insights, concerns, and ideas, in response to questions about coastal changes and potential interventions:
• Pre-Contact Map: Identify landscape components (cultural, vegetated, hydrological) that should be maintained or restored, drawing from traditional land use to guide contemporary resilience strategies.
• Plantation Era Map: Identify the environmental consequences of plantation era land uses (e.g., sedimentation, altered waterways, land degradation), while also noting landscape elements worth preserving.
• Resilient Future Map: Highlight opportunities for biocultural restoration sites, ecosystem strengthening, recreational enhancements, highway reuse or removal, and seawall removal.
As a supplement to the three maps, the project team provided participants with educational boards focusing on nature-based solutions (NbS), traditional ecological knowledge (TEK), and sea-level rise adaptation intended to inform responses.

If left in place, the existing highway may eventually act as a hardened shoreline, leading to significant impacts such as beach loss and loss on critical habit.
There was a cost analysis in the book Thinking about Traffic in West Maui and what Judith said.
Honoring traditional wisdom and Hawaiian stewardship practices to guide the way forward.
Thriving native shorelines, Healthy coral reefs supporting marine life and naturally buffering waves.
Take knowledge from historic land use (native tree plantings)
Restored fishponds that blend tradition with sustainability, protecting marine habitats.
Public beaches with open access for everyone to enjoy.
Think of the reduction in miles driven
Gathering spaces with shaded areas, walkways, and places to connect with nature.
Balanced development that considers the long-term health of the coast.
I’m not a scientist, but many old time farmers say it doesn’t rain like it used to. In my 65 years, I’d say the same. We should embrace weather trends and not try to get more water when rainfall is going down (maybe).
Remove all sea walls, remove existing highway in areas that already will be underwater
Remove sea walls and highway sections that intersect with 3.2 ft SLR-XA at times based on planned triggers. Create an adaptation plan similar to DPR’s beach park adaptation plan for Hoaloha BP under development.
Perhaps remove the highway and encourage more native vegetation and wetlands near Ukumehame and places of the road that get wet during king tides? Just a thought...
Expand recreational & park opportunities at Ukumehame and encourage native vegetation with educational signs and information.
Coastal area is such a special place for gathering/collecting, and we should keep the space open for people who use the coastline
Recreation focused away from the coastline, and reserve the coastline as a space for people to come together, gather
In terms of re-imagining public spaces – Papalaua Wayside Park that is in the SLR-XA zone with the sedimentation basin directly mauka, Ukumehame Firing Range, wetlands, archaeological sites, etc. is somewhere I could see creative (and challenging) landscape architecture solutions (that incorporate nature-based solutions). Especially as a cul-de-sac is proposed here in the HDOT EIS proposed alternative.
Remove sea wall west of Papalaua Wayside Park, create layered living shoreline systems, turn old highway into elevated boardwalk, and (re)establish salt marsh.
Any proposed work should not accelerate the impacts of SLR and erosion to impact the reliability of the realigned highway
Considering removal of the existing highway in areas of known nene habitat to help protect the species
I can concur, from the data, that rainfall has been declining since the 80s, and are predicted to continue to decline.
If we put a tunnel through the mountain from Wailuku….you could eliminate the road past Maʻalaea all the way to Olowalu.

In-Person and Virtual Engagement Event Results (2/6/25, 2/11/25, 2/13/25)
After today’s meeting, what word comes to mind when you think about the future of the coastal area?
At the end of the in-person engagement event, participants were invited to respond to an exit question displayed on a whiteboard: “After today’s meeting, what word comes to mind when you think about the future of the coastal area?” This final exercise encouraged reflection on the discussions and ideas shared throughout the event.
As with the entry question, participants wrote their responses directly on the whiteboard. During the two virtual events, participants answered the same question through Mentimeter, a digital engagement tool that allowed them to submit responses in real time.
The resulting word cloud visually summarizes the collective sentiment from both in-person and virtual participants. In the graphic, larger words indicate more frequent mentions, illustrating key themes. The responses revealed a shared vision for resilience, sustainability, and the opportunity that the relocation of the Honoapiʻilani Highway brings.
Top responses from participants were:
• Resilience (6)
• Hope (3)
• Wetlands (3)
• Living shorelines (2)
• Malama (2)
• Opportunity (2)
