Based on NOAA Technical Report 083 (Sweet et al. 2022). Six scenarios, 14 tide gauge stations, station-specific vertical land motion — delivered as a REST API for engineers and planners.
Straight from NOAA's latest science — station-specific projections with local vertical land motion, delivered as simple API calls.
Official 2022 NOAA scenarios (Sweet et al.) from Low to Extreme. Each station incorporates local relative sea level rise including vertical land motion.
Gulf and South Atlantic coast coverage from Key West to Grand Isle. Station-specific RSLR tables with decadal anchor points from 2020 to 2100.
Combine SLR offset with CVG Storm Surge Wizard for compound event modeling — critical for FEMA BFE + SLR adjustments and resilience planning.
Sub-decadal year precision via linear interpolation between anchor years. Request any year from 2020–2100 and receive a calibrated projection in meters.
Request all 6 scenarios simultaneously via /slr/sensitivity for complete scenario envelope analysis from Low to Extreme.
Supply your own override_slr_m value when working with site-specific studies or local agency guidance while preserving the standard API workflow.
From conservative infrastructure planning to extreme climate resilience — select the scenario that matches your project's risk posture and planning horizon.
| Scenario | API Name | Risk Level | Key West 2050 (m) | Key West 2100 (m) | Best For |
|---|---|---|---|---|---|
| Low | low | Low | ~0.15 | ~0.30 | Optimistic planning, long-cycle assets |
| Intermediate-Low | intermediate_low | Low-Med | ~0.25 | ~0.50 | Conservative infrastructure |
| Intermediate | intermediate | Medium | ~0.35 | ~0.70 | General planning standard (recommended) |
| Intermediate-High | intermediate_high | Med-High | ~0.50 | ~1.05 | Critical facilities, FEMA BFFF |
| High | high | High | ~0.65 | ~1.40 | Long-lived infrastructure, resilience planning |
| Extreme | extreme | Extreme | ~1.00 | ~2.50 | Catastrophic risk, conservative coastal retreat |

No spreadsheets, no manual lookups — structured JSON in, calibrated sea level rise offset out.
Pick the nearest NOAA CO-OPS tide gauge station from the 14-station catalog covering the Gulf and South Atlantic coasts.
Select one of 6 NOAA scenarios and specify your planning horizon year (2020–2100). The API interpolates between anchor points automatically.
A single GET request returns the SLR offset in meters along with metadata including the station name, VLM estimate, and TR-083 citation.
Add the offset to your base flood elevation or storm surge water surface — or pass it directly to Storm Surge Wizard for compound modeling.
Freeboard calculations for bridges, seawalls, and stormwater outfalls with future sea level accounted for across planning horizons.
CZMA compliance analysis, FEMA Risk MAP, and sea level rise vulnerability assessments for state and local governments.
Stack SLR offset onto storm surge scenarios for worst-case compound event analysis — integrated directly with Storm Surge Wizard.
Identify areas that transition into chronic flooding risk under Intermediate and High NOAA scenarios over 30-year planning cycles.
Align infrastructure investment timelines with SLR exposure windows across multiple scenarios for risk-adjusted decision-making.
Generate defensible SLR projections for SEC/TCFD climate risk disclosures, bond prospectuses, and asset-level reporting.
All plans include all 6 NOAA scenarios, 14 stations, and HTTPS access. Bundle with Storm Surge Wizard for compound flood workflows.
