Some coastal cities are rushing to prepare for rising sea levels, but Coronado – surrounded almost entirely by the ocean and a bay – is not one of them.
Sea-level rise could affect what’s on Coronado already, as well as future development in the city and Navy property. Everything from a new city beach bathroom to a new $700 million Navy facility could be impacted. As oceans rise, beaches may erode, tides will creep in and storms will cause worse floods.
While the Navy has made some preparations of its own for climate change on Coronado, the city itself has not.
Though the major effects are still decades away, Imperial Beach, just south of Coronado, is talking now in clear terms about the costs and consequences of rising oceans.
David Revell, a climate scientist working to prepare Imperial Beach for sea-level rise, said that Coronado has been absent from regional discussions.
“So they need to be in the room discussing this,” Revell said during a recent Imperial Beach City Council meeting.

Sea level, historically measured by tide gauges and by satellite altimetry since 1992 show no significant net increase in global sea level at all. The TOPEX/POSEIDON sea-level monitoring satellite, which operated from 1993-2000, showed no sea-level trend. The GRACE gravitational-anomaly satellite, able to measure ocean mass, from which sea-level change can be directly calculated, found that sea level actually fell slightly from 2002-2007. These two satellite systems, using very different measurement methods, produced raw data resulting in identical conclusions: sea level is barely rising, if at all.
Since most Coronado residents are republicans, they expect their denial to protect them from climate change. Stupid!
Stupid is being ignorant of the scientific facts about sea level change.
I've lived in Mission Beach on the bay side for 28 years. I haven't noticed any rise in the height of the bay. Each year the Park and Rec Dept. creates a berm for the winter high tides, then flattens it as summer approaches. We're pretty close to water level, but so far, so good.
The Dutch solved their sea level problem and I'm sure the U.S. can as well when it becomes necessary.
The solution is to copy ancient engineering techniques used around the world for liquefiable soils and foundations, in port cities.
1. Re-Establishing a new United State Bulkhead Elevation for San Diego Bay. The original 1850 US Bulkhead Elevation for San Diego Bay has not changed in 166 Years.
2. Force new Infrastructures on State Public Tidelands and liquefaction soils to built on Structural Cistern Foundations using the same Bulkhead design used in Ship Building, and Dry Docks. There are 2 types of Foundations. When feasible, Foundations should be build on Rock, not sand. The shallow depths to formation in San Diego Bay allows for low-cost Structural Cistern Foundation solutions.
3. Funding would come from moving all Infrastructure Capital Improvement Programs (CIP) for the Airport and Port to SANDAG our Metropolitan Planning Organization (MPO). San Diego is 1 of 12 Grandfathered Airports where FAA Revenue can be used outside the Airport. The Port Cities of New York/New Jersey, Washington, DC, San Francisco, Chicago all used FAA Airport Revenue to build their public infrastructure, transit, and subways.

Thank heavens there is still a rational city in San Diego County that refuses to spend taxpayer dollars to solve a non-existent problem. The sea level is not rising... and the global warming scare-mongers are getting desperate.
@William Charles I agree that taxpayer dollars from the general population shouldn't be spent to benefit wealthy coastal homeowners. If they feel it necessary, let them tax themselves or retreat to higher ground.
