Brief Communication: Bridging the data gap – enhancing the representation of global coastal flood protection
Abstract. Understanding coastal flood protection is crucial for assessing risks from natural hazards and climate change. However, there is a significant lack of quantitative data on coastal flood protection and their standards. FLOPROS, currently the only global database of flood protection standards, relies on limited coastal observations and simplified assumptions. Despite these limitations, it is widely used by the research community, leading to potential uncertainties in impact estimates. We propose that a new community-driven effort is needed to develop a more complete dataset, and we present COASTPROS-EU, a dataset compiling coastal flood protection standards within Europe. This effort further highlights the urgent need for enhanced information. Establishing an accurate dataset requires using both bottom-up and top-down approaches and ensuring diverse societal representation.

The authors have presented a new database of coastal flood protection measures in Europe, in alignment with FLOPROS.
Given the focus on sharing this database through this Brief Communication, I would encourage the authors to include the following, along with some minor comments thereafter:
- Please further describe the methodology for constructing this database. The only description in this manuscript is the one sentence at Line 104, which leaves a lot of questions about the methodology and its reliability, and the quality of this data.
- Please comment on the quality of this dataset, and how it compares with that of FLOPROS and its coastal update by Tiggeloven et al. (2020). What further advantages does this dataset provide over the existing dataset?
- Line 17 - It is prominently mentioned in the abstract that “a new community-driven effort is needed to develop a more complete [coastal flood protection] dataset”. However in the remainder of the manuscript, it did not appear that such a community driven effort was employed for developing COASTPROS-EU. Additionally, no information was provided about how such a community driven effort may be implemented.
- Is COASTPROS an acronym?
- Line 37 - The phrase “assessing current flood protection levels” is unclear. Are the authors referring to flood protection measures?
- Line 37 - It would be helpful if the authors included some examples of the complexity and challenges, along with their respective references.
- Line 51 - What is the difference between sub-country units and “regions” in Line 53?
- Line 52 - What complexities are the authors referring to?
- Line 54 - The second comma seems unnecessary.
- Line 60 - *and* UNEP.
- Line 67 - It would be helpful if the authors provided some supporting evidence regarding the “limitations in FLOPROS, especially the limited number of observations for coastal flood protection”.
- Line 76 - What “new observations” are the authors referring to?
- Line 83 - *and* USA.
- Line 98 - What is a NUTS2 region?
- Line 99 - The 3 layers appear quite similar to those of FLOPROS. What are the differences between this methodology and FLOPROS?
- Line 105 - What is the CoCliCo network?
- Fig 1 - The clarity of the figure could be improved by using more contrasting colors.

Short summary
Understanding coastal flood protection is vital for assessing risks from natural disasters and climate change. However, current global data on coastal flood protection is limited and based on simplified assumptions, leading to potential uncertainties in risk estimates. As a step in this direction, we propose a comprehensive dataset, COASTPROS-EU, which compiles coastal flood protection standards in Europe.
