Ramsey County Multi-Hazard Mitigation Plan, 2018 Page | 65 Ramsey County specific building data was sourced from the parcel tax and spatial databases to include building valuations, occupancy class, square footage, year built, and number of stories. GIS data layers named CDSTL_AttributedParcelPoly, CDSTL_AttributedParcelPoint, and STRUCT_Building were obtained from the county to locate buildings within the county. The resulting spatial dataset included 166,407 unique parcel numbers; 153,950 of these records were identified as having building values and were used in the analyses. In cases where values were missing, values were assigned based on best practices from values in the other variables and from the region. The data were then assigned to one parcel centroid, or building location, which served as a surrogate for each parcel’s buildings to aggregate to the associated census block for use in the Hazus model. According to the Ramsey County general building stock (derived from the county’s parcel data and imported to the Hazus model), the Hazus model estimates there are 153,950 parcels with buildings in the region with a total value (excluding contents) of $40.8 billion (2010 dollars). Approximately 95.77% of the buildings (and 72.16% of the building value) are associated with residential housing. The Hazus model estimates 1,294 parcels’ buildings will be at least moderately damaged (>10% damage). 159 buildings are estimated to be completely destroyed. The estimated total economic loss from the flood is $907.55 million dollars. Building-related losses are broken into 2 categories: direct building losses and business interruption losses. The direct building losses are the estimated costs to repair or replace the damage caused to the building and its contents. The business interruption losses are associated with inability to operate a business because of the damage sustained during the flood. Business interruption losses also include temporary living expenses for people displaced from their homes because of the flood. The estimated total building-related losses is $478.64 million dollars. 47% of the estimated losses are related to business interruption in the region. Residential occupancies make up 28.29% of the total loss. The reported building counts should be interpreted as degrees of loss rather than an exact number of buildings exposed to flooding. These numbers were derived from aggregate building inventories, which are assumed to be dispersed evenly across census blocks. Hazus requires that a predetermined amount of square footage of a typical building sustain damage to produce a damaged building count. If only a minimal amount of damage to buildings is predicted, it is possible to see zero damaged building counts while also seeing economic losses. The total estimated number of damaged buildings (parcels as a surrogate), total building losses, and total economic losses for the 100-year flood are shown in Table 21. The distribution of economic losses for Ramsey County is depicted in Figure 13.
