The system includes at least one processing component, at least one memory component, and a data manager configured to define a ledger for a zone, and extract flood data for the zone from at least one information source. The system also includes a risk analyzer configured to generate flood attribute values based on the extracted flood data. The risk analyzer is also configured to calculate a zone risk score based on these values, determine that the zone risk score is above a threshold risk score, and in response, instruct the data manager to add a block to the ledger. ## Claims ### Claim 1 A system, comprising: at least one processing component; at least one memory component; a data manager configured to: define a ledger for a zone; and extract flood data for the zone from at least one information source; and a risk analyzer configured to: generate flood attribute values based on the extracted flood data; calculate a zone risk score based on the flood attribute values; determine that the zone risk score is above a threshold risk score; and in response to the determining, instruct the data manager to add a block to the ledger. ### Claim 2 (depends on 1) The system of claim 1, wherein the risk analyzer is further configured to calculate a location risk score for a location based on the zone risk score and user-input information about the location. ### Claim 3 (depends on 2) The system of claim 2, further comprising a report generator configured to generate a risk report for the location. ### Claim 4 (depends on 2) The system of claim 2, wherein the user-input information includes a lot drainage type. ### Claim 5 (depends on 1) The system of claim 1, wherein the data manager is further configured to: extract additional flood data for the zone from the at least one information source; and wherein the risk analyzer is further configured to: generate additional flood attribute values based on the additional flood data; calculate an updated zone risk score based on the additional flood attribute values; determine that the updated zone risk score is outside a threshold risk score range; and in response to the determining, instruct the data manager to add a next block to the ledger. ### Claim 6 (depends on 1) The system of claim 1, wherein the at least one information source includes weather data. ### Claim 7 (depends on 1) The system of claim 1, wherein the at least one information source includes insurance claims. ### Claim 8 A method, comprising: defining a ledger for a zone; extracting flood data for the zone from at least one information source; generating flood attribute values based on the extracted flood data; calculating a zone risk score based on the flood attribute values; determining that the zone risk score is above a threshold risk score; and in response to the determining, adding a block to the ledger. ### Claim 9 (depends on 8) The method of claim 8, further comprising calculating a location risk score for a location based on the zone risk score and user-input information about the location. ### Claim 10 (depends on 9) The method of claim 9, further comprising generating a risk report for the location. ### Claim 11 (depends on 9) The method of claim 9, wherein the user-input information includes a lot drainage type. ### Claim 12 (depends on 8) The method of claim 8, further comprising: extracting additional flood data for the zone from the at least one information source; generating additional flood attribute values based on the additional flood data; calculating an updated zone risk score based on the additional flood attribute values; determining that the updated zone risk score is outside a threshold risk score range; and in response to the determining, adding a next block to the ledger. ### Claim 13 (depends on 8) The method of claim 8, wherein the at least one information source includes weather data. ### Claim 14 (depends on 8) The method of claim 8, wherein the at least one information source includes insurance claims. ### Claim 15 A computer program product, comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause a device to perform a method, the method comprising: defining a ledger for a zone; extracting flood data for the zone from at least one information source; generating flood attribute values based on the extracted flood data; calculating a zone risk score based on the flood attribute values; determining that the zone risk score is above a threshold risk score; and in response to the determining, adding a block to the ledger. ### Claim 16 (depends on 15) The computer program product of claim 15, further comprising calculating a location risk score for a location based on the zone risk score and user-input information about the location. ### Claim 17 (depends on 16) The computer program product of claim 16, further comprising generating a risk report for the location. ### Claim 18 (depends on 15) The computer program product of claim 15, further comprising: extracting additional flood data for the zone from the at least one information source; generating additional flood attribute values based on the additional flood data; calculating an updated zone risk score based on the additional flood attribute values; determining that the updated zone risk score is outside a threshold risk score range; and in response to the determining, adding a next block to the ledger. ### Claim 19 (depends on 15) The computer program product of claim 15, wherein the at least one information source includes insurance claims. ### Claim 20 (depends on 15) The computer program product of claim 15, wherein the at least one information source includes weather data.
