Abstract: This study examines the factors influencing home elevation decisions among participants in Houston’s Homeowner Assistance Program (HoAP) and the Texas General Land Office’s Homeowner Assistance Program (HAP) in the aftermath of Hurricane Harvey and other flood events. Using a mixed-methods approach, we conducted surveys and semi-structured interviews with 50 homeowners, supplemented by secondary data analyses of program records and GIS-based flood risk assessments. Additionally, 25 undergraduate students engaged in a structured field trip, conducting site observations, interacting with residents, and discussing home elevation with experts. The findings reveal disparities in home elevation outcomes, with lower completion rates in socially vulnerable neighborhoods despite program eligibility. The study also identifies key factors influencing elevation decisions, including mobility concerns, financial constraints, neighborhood esthetics, and perceptions of long-term flood risk. Homeowners aged 60–79 were more likely to elevate their homes, while individuals with disabilities faced additional barriers. This research highlights the need for targeted policy interventions to improve program equity and ensure that vulnerable populations receive adequate support. Beyond its case study implications, this research contributes to broader discussions on disaster recovery, climate adaptation, and urban resilience. It also serves as a model for integrating student learning into community-based participatory research. While this study is limited in scope, it offers insights into the intersection of social vulnerability and housing adaptation, informing future policy efforts to enhance flood resilience in historically marginalized communities.
