Housing And Urban Development Home Development And The Future Of The Industry: Case Study, Nolan J. Binkele

Construction Management

A HUD home is a 1-4 unit residential property acquired by HUD (Housing and Urban Development) as a result of a foreclosure action. These homes tend to be priced slightly below market value in order to regain past losses. The Department of Housing and Urban Development has developed a building code to classify manufactured homes as HUD. Although manufactured homes are typically sold to single property owners, I hypothesize that building them in a tract form can benefit a community by providing affordable, adequate housing for low income families and single families. I also hypothesize that HUD home development will …

Thus, this dissertation adopted the 50-Item Personality questionnaire developed by Goldberg, which consited of extraversion, aggreeableness, conscientiousness, neuroticism, and openness to experience. The literature also revealed several common team criteria to evaluate team performance: team member satisfaction, shared …

Single-Family Residential Flood Loss Reduction Through Freeboard, Ehab Said Gnan

LSU Doctoral Dissertations

The lack of flood loss estimation methods conducted on a micro-scale level that consider the full loss‐exceedance probabilities curve poses a significant problem in flood risk assessment. Also, the lack of robust benefit-cost analysis (BCA) that quantifies benefits at the micro-scale level leads to sub-optimal results, and therefore sub-optimal decisions when determining the optimal freeboard. Further, flood loss assessments focus on owner-occupied housing and neglect rental housing. These loss assessment deficiencies underscore the need for a robust assessment that quantifies the life-cycle benefits for all stakeholders and provides actionable information to enable informed decisions.

This research presents a comprehensive methodology …
