Florida design wind · ASCE 7-22 · Risk Category II
50 of 67 counties sampled, calibrated against ASCE
Wind bands · mph · field interpolated from 50 samples
The inputs are public. Assembling them is the job.
None of this data is secret. It is scattered across four agencies, three formats, and a viewer that times out.
Open the ASCE hazard tool, re-enter the coordinate, run each risk category one at a time, screenshot the result
All four risk categories returned in one call, with the ultimate and nominal speeds and the exposure assumption stated
Take a wind speed off a printed contour map and interpolate by eye between the 140 and 150 lines
Interpolated against FGDL/UF contour geometry in PostGIS, with the bracketing contour pair reported so you can check the arithmetic
Chase seismic site class through a separate tool that assumes a default you did not choose
Ss, S1 and site coefficients returned with the site class you select, not one we assumed
Cite a flood zone from a map image and hope the BFE has not been revised since the panel date
FEMA NFHL zone, BFE and SFHA status with the effective date carried alongside the value
What comes back for a site
One address in. Every value below carries its source, its vintage, and how it was derived.

Put the criteria where the calc already lives
Design criteria is a lookup, not a judgement. Hand the lookup to an agent and keep the judgement where it belongs.
In your modelling workflow
Connect over MCP and let your assistant fetch wind, seismic and flood inputs for a site while you stay in the model. No tab, no re-keying, no transcription error.
Across a whole portfolio
Feed a list of addresses through the REST API and get design criteria for every one. Useful for existing-building surveys and multi-site scopes.
With the provenance intact
Every response carries its source, date, and derivation. When a reviewer asks where 166.2 mph came from, the answer is in the payload rather than in your memory.
Pull ASCE 7-22 design criteria for 1200 Brickell Ave, Miami — all four risk categories, site class D, and tell me which contours the wind speed was interpolated between.
How it works for you
Design criteria sheets
Populate the criteria block on a drawing set without opening four separate tools. The values arrive with the citations a plans examiner will look for.
Existing building assessment
Compare the design criteria in force today against what applied when the structure was permitted. Year built and the current criteria come back in the same report.
Peer review and defence
Show the derivation, not just the number. The bracketing contour pair and the ASCE cross-check are part of the record rather than something to reconstruct later.
Questions we actually get
Where does PropDocket's design wind speed come from?
From FGDL/UF ASCE 7-22 contour geometry held in PostGIS. A point query widens through 1, 5, 15, 50 and 100 mile buffers until it finds intersecting contours, then interpolates between the bracketing pair. ASCE runs as an independent cross-check, not as the runtime source. It is not a substitute: if the contour query cannot answer, the response reports that rather than quietly swapping in a different source. Every response reports which contours the value came from.
How close is it to ASCE?
Across 50 Florida county samples at Risk Category II, mean absolute error was 1.62 mph, P90 was 2.77 mph, and the worst case was 3.88 mph. All 50 fell within 5 mph. The per-county comparison is plotted on this page so you can check any of them.
Can I get all four risk categories in one call?
Yes. One address returns Risk Categories I through IV, with the exposure assumption stated rather than implied.
Do you pick the seismic site class for me?
No. Site class is yours to choose, and the seismic parameters come back for the class you select. We do not assume a default and let it silently propagate into your calc.
Is this a substitute for a sealed determination?
No. PropDocket returns design criteria with sources and dates attached. Applying them, selecting the governing case, and sealing the result remains engineering judgement and remains yours.
