Assessing the vulnerability of coastal wastewater infrastructure to climate change

PI: Daniele Spirandelli
This research aimed, with community and agency stakeholders, to identify and map critical factors contributing to wastewater infrastructure vulnerability to a changing climate, particularly sea-level rise and extreme precipitation, and to develop a process that builds adaptive capacity into the system. Results showed groundwater inundation as a significant threat to sewer pipes, and a policy gap analysis identified discontinuities in key components of Hawaiʻi’s current onsite management program between land-use planning efforts and state siting regulations.

Do seawalls lower property values?

PI: John Lynham
This work examined the economic consequences of a strategy commonly used in years past of building sea walls to protect property threatened by increased coastal erosion. Based on a technique previously used successfully by the authors in San Diego, CA, the researchers examined property sales on Oʻahu for the last 30 years and combined this with locations of seawalls built over those years. They found that while properties with coastal armoring maintain their value, there is evidence that neighboring properties show a decrease in value with time.

Integrating climate science with local knowledge through community vulnerability assessment on Kauaʻi

PI: Daniele Spirandelli
This study examines the opportunities and challenges of integrating coastal resilience into local community plans, using the County of Kauaʻi’s efforts as a case study. Researchers will combine broader climate science risk information with local knowledge to support statewide goals to prepare counties for future climate hazards.

Integrating Coastal Hazards and Sea Level Rise Resilience in Community Planning

Over the past decade, Hawai‘i has progressed in recognizing and addressing coastal hazards and the need for adaptation to sea level rise. However, more work still needs to be done to translate broad-scale guidelines and scientific information into action at ...
