The proposed Cape Fear Bridge length for this alternative is 3.11 miles long.During the low SLR scenario, the alternative will have 0.42 miles of roadway underwater. This alternative is projected to have the greatest amount of roadway underwater during the low scenario. The intermediate scenario predicts that the alternative will have 0.58 miles of flooded roadway. The high scenario projects that 1.62 miles of roadway would potentially be inundated by 2100.Areas along Alternative MA that are at-risk for inundation are identified in Figure 8.The majority of these areas are marked to the west of the Cape Fear River,on NC 133 (River Road),and north of Town Creek.

Three sand mines in Horry County were selected along with one mine in Brunswick County which offered the most comparability to the subject. • Our analysis begins in 2009,which is a post-crash recovery period in which market appreciation would be anticipated over a longer time period. • The subdivision adjacent to sand mining operations is identified as the"sample subdivision"and subdivisions within close proximity,but far enough to be unaffected by the mining noise,traffic,etc.,are identified as the "comparative subdivisions." • The sales volume and average sales price from each year within the sample subdivision,comparative subdivisions and Horry County were tabled and graphed for comparison. Active mining periods were also identified within this data in an effort to show a percent change on an annual basis and to track short-and long-term trends during these mining periods. • Only one of the four sample subdivisions analyzed had a haul road which passed residential homes with a minimal buffer area,similar to the proposed sand mine operation. • After analyzing the data,there appeared to be no significant economic impacts on home values.Although some volatility existed during periods of active mining in the sample subdivisions,volatility was also observed in the comparative subdivisions which means this volatility can not be solely attributed to the mining operations. • None of the sample subdivisions experienced more than one single year of percentage decline in value,and this decline was offset within two years or less by continued increases. • Comparing the percentage change in average home values from the year prior to the start of mining operations to the last year of mining operations,three of sample subdivisions had increases on par with the comparative subdivisions and the County. In the one instance where the average value increase in the sample subdivision was less than the County,it was still on par with the comparative subdivision. • Observing a single data point in an analysis may lead a casual observer to believe the property values are negatively impacted, but an observation over the mining periods(which ranged from 4 to 8 years in the mines selected for comparison)does not appear to negatively impact the property values.
