Billions for sea walls in the next 20 years
By Mathew Goldstein
Virginia is No. 4 and Maryland is No. 5 when it comes to states facing massive expenditures to prepare for sea level rise, behind only Florida, Louisiana, and North Carolina. Virginia will need to spend about 31 billion to build 4,928 miles of sea walls between now and 2040 to protect coastal communities from sea level rise. Of that total, 15 billion is for the 1st congressional district and 11 billion for the 2nd congressional district. Virginia Beach is 1.7 billion. The county numbers include 4.9 billion for Accomack, 2.3 billion for Northumberland, 2.2 billion for Mathews, 2.1 billion for Gloucester, 1.7 billion for Northampton, 1.3 billion for Middlesex, and 1.2 billion for Westmoreland. This analysis is based on modest sea-level rise projections that assume some reductions in carbon emissions according to the Institute for Governance and Sustainable Development’s Center for Climate Integrity (“High Tide Tax: The Price to Protect Coastal Communities from Rising Seas”).
Maryland, whose state budget is $45.2 billion, will need to spend about $27.4 billion to build 2,996 miles of sea walls. Dorchester County will need $6.5 billion for sea walls. Also, Somerset County ($3.1 billion); Worcester County ($2.7 billion); St. Mary’s County ($2.6 billion); Talbot County ($2.4 billion); Anne Arundel County ($1.9 billion); Queen Anne’s County ($1.8 billion); Kent County ($1.5 billion); Wicomico County ($1.3 billion); and Charles County ($1.2 billion). Maryland’s 1st congressional district has the second highest projected need of any congressional district in the country – more than $20.4 billion. For some sparsely populated localities in Maryland the per capita cost of the sea wall is over 1 billion which implies that those towns may be abandoned.
