Appendix E Information on Historic Resources and Sea Level Rise Historic Resources, Sea Level Rise and Climate Change Historic resources in South Florida are vulnerable to sea level rise, flooding, and impacts of climate change such as increased hurricanes. There is an increasing recognition that historic structures need to adapt in order to be protected long-term. At the federal level, the National Park Service has issued guidelines on flood adaptation for rehabilitating historic buildings. Last month, the Advisory Council on Historic Preservation adopted a policy on climate impacts to historic places. Many other communities have adopted guidance at the local level to address changes to historic structures that are necessary to mitigate for flooding and sea level rise. In the most recently available Florida Comprehensive Historic Preservation Plan, the state acknowledges the need to address long-term threats to historic properties in the state, including sea level rise. Locally, Miami -Dade County's Office of Historic Preservation completed a vulnerability assessment of County -designated historic properties and an update to their design guidelines that focus on resilience. Miami Beach has adopted guidelines for adaptation and mitigation of historic resources in the face of flooding and sea level rise. 334 Atlantic Avenue 334 Atlantic Avenue's proximity to the water is a significant feature of the property. The original 1984 County designation includes information on the "environmental responses of its design." It notes that the property is "built on the water's edge, in the same way that buildings in Venice come up to the canals." It further notes that water is within view of the house on three sides, taking the place of a backyard. "The house responds beautifully to its surroundings, making maximum use of the prevailing breezes of its rear oceanside location. Window groups, set in cross ventilation patterns, balconies, roof overhangs, a central courtyard facing directly over the canal, and the building's multiple massing, are all part of the environmental techniques employed." The property is located on the water in an AE8 flood zone. The Miami -Dade County Flooding Vulnerability map shows a parcel mean elevation of 1.99 feet. Sea level rise vulnerability shows that there is no permanent inundation after 1 foot of sea level rise using the 2040 NOAA Intermediate -Low or Intermediate -High sea level rise estimates. However, under the 2070 NOAA Intermediate -High sea level rise estimates there would be permanent inundation of the site after 1 foot or higher rise.
