Being low-lying and largely surrounded by water, Norfolk is particularly vulnerable to [[Sea level rise|rising sea levels]] caused by [[climate change]].<ref>{{Cite magazine |last=Arnold |first=Carrie |date=December 27, 2020 |title=Rising to meet the tide against the threat of coastal flooding |url=https://arstechnica.com/science/2020/12/rising-to-meet-the-tide-against-the-threat-of-coastal-flooding/ |access-date=2020-12-28 |via=Ars Technica |magazine=Knowable Mag |language=en-US}}</ref> In addition, the land on which it is built is [[Subsidence|slowly subsiding]]. Some areas already flood regularly at high tide, and the city commissioned a study in 2012 to investigate how to address the issue in the future: it reported the cost of dealing with a sea-level rise of one foot would be around $1,000,000,000. Since then, scientists at the [[Virginia Institute of Marine Science]] in 2013 have estimated that if current trends hold, the sea in Norfolk will rise by 5 and 1/2 feet or more by the end of this century.<ref name=":0">{{cite news |last=Montgomery |first=Lori |url=https://www.washingtonpost.com/business/economy/in-norfolk-evidence-of-climate-change-is-in-the-streets-at-high-tide/2014/05/31/fe3ae860-e71f-11e3-8f90-73e071f3d637_story.html |title=In Norfolk, evidence of climate change is in the streets at high tide |newspaper=The Washington Post |date=2014-05-31 |access-date=2016-06-21}}</ref><ref name=":1">{{cite news |last=Jarvis |first=Brooke |url=https://www.nytimes.com/2017/04/18/magazine/when-rising-seas-transform-risk-into-certainty.html |title=When Rising Seas Transform Risk Into Certainty |newspaper=The New York Times |date=2017-04-18 |access-date=2018-08-01}}</ref>
