SBIR Phase II: Microbially-driven underground barrier to reduce flooding in coastal communities -the broader/ commercial impact of this small business innovation research (SBIR) Phase II project lies in mitigating escalating bottom-up flood risks by commercializing nature-based technology to reinforce porous limestone. This innovation reduces flood damage, saltwater intrusion, and seawall failure in at-risk coastal regions, such as florida. By strengthening critical infrastructure and protecting natural resources, the project enhances public safety and quality of life while lowering long-term maintenance costs and minimizing resident disruption. Furthermore, this work advances the national interest in economic security and resource conservation, fulfilling the mission of translating scientific research into tangible public benefits through successful commercialization. The primary technical challenge of this project is determining whether controlled carbonate mineral formation can achieve the scale, uniformity, and durability required to create low-permeability subsurface barriers within porous coastal limestone. This is inherently high-risk due to the extreme heterogeneity of coastal geology, which is subject to high permeability, variable groundwater flow, and fluctuating chemical conditions from seawater intrusion. A successful outcome would establish a novel subsurface appr ...

The Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) programs set aside part of federal research budgets for small companies. Agencies award them in phases: Phase I tests whether an idea is feasible, Phase II funds development, and Phase III is follow-on work paid for outside the set-aside. STTR awards also require a research institution as a partner.
Every figure on this page is taken from the award's own federal record, linked beside it, as it stood when the page was built: the recipient, its address, the awarding agency and office, the amount obligated so far, the dates and the description. Phase and program are shown as the award's own description states them. The amount can grow later if the agency adds funding to the same award.
