Today’s visitors to this beloved tourist destination—and there are many!—can still walk the same brick sidewalks along the Severn River or enjoy a rich meal and flagon of ale at the same pubs and taverns as Americans did at the time of the nation’s founding. That is why we at the National Trust named Annapolis one of our National Treasures in 2014. It is a City with deep national and historic significance—and one that, due to the rising sea levels that are accompanying accelerating climate change, is now under threat. Longtime Annapolis residents can testify to the transformations. In the early 1960s, the downtown area experienced nuisance flooding at high tide only three days a year. Today, flooding occurs between thirty and forty days a year. By 2030, according to a study by the Union of Concerned Scientists (UCS), it will flood every other day. By 2045, downtown will flood every single day. These rising waters represent more than just a nuisance. They present clear risks to the City’s many distinctive historic and cultural assets, from the nearly 275‐year‐old Sands House to local watering holes like Middleton’s and McGarvey’s, the sailboats at City Dock to the Alex Haley / Kunta Kinte Memorial downtown, and to all the public spaces around the historic market slip. Thankfully, Annapolis’s municipal leaders have recognized these risks, understand that these historic places are community and economic assets that must be protected for the long term, and have taken important, concrete steps to preserve the future of downtown Annapolis. Under the guidance of Mayor Mike Pantelides and Chief of Historic Preservation Lisa Craig, the City has assembled the wide‐ranging Weather It Together coalition to raise awareness of flooding dangers and come up with innovative mitigation and adaptation solutions. They have explored 21st‐century technologies like GIS mapping and mobile LiDAR (Light Detection and Ranging) to survey historic resources in Annapolis and analyze the potential impacts of increased flooding. And with the Weather It Together v WEATHER IT TOGETHER: CULTURAL RESOURCE HAZARD MITIGATION PLAN plan now before you, Annapolis becomes the first city in the United States to have created a cultural resource hazard adaptation and mitigation plan. The challenges posed by rising seas and a warming climate will not affect Annapolis alone. The Union of Concerned Scientists (UCS) identified many communities along our coasts, as well as many beloved national landmarks, that are also under threat from these changes. Taken in whole, the preservation challenges before us can seem very daunting. But with this plan, and all of the hard work over the past few years, Annapolis is showing us a way forward—one based on clear‐eyed analysis, thoughtful resilience planning, innovative technology, and creative partnerships. The Sailing Capital has always been a shining beacon of our American past. With this plan, Annapolis now also lays out an important claim to our future. With warmest regards, STEPHANIE K.
