Claims, one by one

The text below is copied verbatim from the published record. Each claim names the source dossiers that carry it; caveats stay attached to the claim they qualify.

Claim 1 clm-830bf0e3236959eb quantitative
The number its own website tells residents to dial, 311 or 305-468-5900, rings at Miami-Dade County's contact centre
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The city's own instruction to residents is 'Dial 311 or 305-468-5900' — the county's number — and the page names no city-run 311 line and no city reporting app. The county's operator page confirms the shared jurisdiction: the centre handles 'a variety of Miami-Dade County and City of Miami services'.
Caveat
No claim-specific caveat recorded

Sources carrying this claim

  1. City of Miami — Solve a Problem
  2. Miami-Dade County — 311 Contact Center (operator)
Claim 2 clm-361eb2cf365413be descriptive
which handles county and City of Miami requests in English, Spanish and Haitian Creole and closes on Sundays
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The operator page, fetched 26 July 2026, gives the hours as 'Monday through Friday from 7 a.m. to 7 p.m. and Saturday from 8 a.m. to 5 p.m., while closed on Sundays and holidays' — not a 24-hour line — and the languages as 'in English, Spanish and Haitian Creole'.
Caveat
No claim-specific caveat recorded

Sources carrying this claim

  1. Miami-Dade County — 311 Contact Center (operator)
Claim 3 clm-643eda8572f2f2de descriptive
it records the channel each request arrived by, a goal in days for its case type, the days actually taken and an overdue flag
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The layer's field list, read on 26 July 2026, carries method_received, goal_days, actual_completed_days, ticket_closed_date_time, OverDueFlag, District and Ticket_Priority.
Caveat
The meaning of OverDueFlag is not documented anywhere this desk could reach, so the entry reports records 'flagged overdue' and claims nothing about resolution.

Sources carrying this claim

  1. City of Miami 311 feature layer (queried directly)
Claim 4 clm-bb1fd73c4ebc5004 quantitative
It ends on 12 August 2024, the day the county moved 311 onto a new platform
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The publisher's own metadata states the layer holds 'point features representing the locations of service requests placed by the public via the county's 311 service system. The dataset displayed encompasses the time range from 2022 to the last available date of August 12, 2024 when Miami-Dade County migrated the 311 system to a new platform.'
Caveat
The item's title says 'Since 2015' and the data does not reach back that far; the entry follows the data, not the title.

Sources carrying this claim

  1. City of Miami 311 Service Requests Since 2015 — ArcGIS item record
Claim 5 clm-3cedd8267f06b988 quantitative
88,078 City of Miami requests in the published extract, counted from the city's own feature layer on 26 July 2026, covering October 2022 to 12 August 2024; calendar 2023 alone ran to 46,481
Published field
impact · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
returnCountOnly on the layer gave 88,078 on 26 July 2026. A group-by on created_year_month gave months 202210 through 20248 and a calendar-2023 total of 46,481; the three yearly blocks sum exactly to 88,078.
Caveat
Counted directly from the published layer by this desk, not taken from any press account or city statement.

What the mapping says
A group-by on method_received gave PHONE 75,600, IPHONE 4,092, ANDROID 1,672, WEB 2,858, EMAIL 2,841, PROACT 872, SOCIALMEDIA 65 and WALKIN 18. The app rows correspond to 311Direct, the county application that lets residents of Miami-Dade County and the City of Miami report problems, attach a photo, stay anonymous and check status.

Claim 7 clm-47e4c0c5c92b9760 quantitative
23,951 records, 27 percent, carry the overdue flag
Published field
impact · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
A group-by on ticket_status and OverDueFlag gave 23,951 records flagged 1, of which 19,908 sit on CLOSED cases, against 62,993 closed and not flagged.
Caveat
The meaning of the flag is undocumented, so this is a count of records flagged overdue and says nothing about whether the underlying problem was resolved.

Claim 8 clm-6640e9925301123f quantitative
Miami-Dade's published series runs 2013 to 2023 and the city's extract stops at the August 2024 migration
Published field
lesson · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
A search of the county's published items on 26 July 2026 returned exactly 11 datasets, all owned by MDPublisher, for the years 2013 to 2023 — no 2024 and no 2025 file. Combined with the city extract's 12 August 2024 cut-off, the public record goes cold after the migration.
Caveat
No claim-specific caveat recorded

  2. City of Miami 311 Service Requests Since 2015 — ArcGIS item record
Claim 9 clm-0f5b0986f1d3eca5 descriptive
no county Inspector General audit has ever checked whether a case marked closed was actually fixed
Published field
lesson · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
Checked on 26 July 2026: the published audit list spans 27 February 2012 to 11 April 2025 and contains no report on 311, on service requests, or on whether closed cases were resolved.
Caveat
A negative finding from the published list. Miami is not the exception — as with New York, San Francisco, Boston and Washington D.C., no independent verification of case closure was found.

Operator page, fetched 26 July 2026. Establishes the shared jurisdiction: the centre handles 'a variety of Miami-Dade County and City of Miami services'. Hours: 'Monday through Friday from 7 a.m. to 7 p.m. and Saturday from 8 a.m. to 5 p.m., while closed on Sundays and holidays' — not a 24-hour line. Languages 'in English, Spanish and Haitian Creole'. Channels: 311 or 305-468-5900, online portal, mobile app, email, social media and three walk-in service centres. The page carries no launch date and no volume figures, which is why neither is sourced here.

The city's own instruction to residents is 'Dial 311 or 305-468-5900' — the county's number. Fetched 26 July 2026; the page names no city-run 311 line and no city reporting app. This is the source for the entry's first sentence, and the reason the county and city are not merged into one operation here.

The county publishes its 311 data as annual snapshots rather than a rolling feed. A search of ArcGIS Online for '311 Service Requests — Miami-Dade County' on 26 July 2026 returned exactly 11 items, all owned by MDPublisher, for the years 2013 to 2023 — no 2024 and no 2025 file. Together with the city extract's 12 August 2024 cut-off, this is the basis for the entry's claim that the public record goes cold after the migration.

Miami-Dade wrote Open311 server code and does not appear to serve it. The wiki lists 'GeoReport v2 Server — Python-based middleware/server by Miami-Dade County', pointing at github.com/miamidade/georeport-server; that repository returned HTTP 404 on 26 July 2026. No live Miami or Miami-Dade GeoReport v2 endpoint was found, so the entry claims no Open311 interface.

Fetched 26 July 2026: the server returned a Salesforce Lightning loading shell reading 'Sorry to interrupt' and 'CSS Error', meaning the portal renders entirely in the browser. Consistent with the county's move to a new platform in August 2024. No public map or list of recent requests could be confirmed by fetching, so the entry claims none.

The weakest fact in this entry, and flagged as such. The county states its 311 Contact Center 'has been helping residents and visitors navigate County services for over 20 years', which puts the start in 2005 or earlier and is consistent with the 2004 date carried by secondary accounts. No primary county document giving the launch date was reached. yearStart should not be treated as sealed.

Known limits of this passport
  • Publisher names and source languages have not yet been classified; domains are recorded without guessing.
  • Existing source notes are descriptive locators, not page- or paragraph-exact citations.
  • A missing archive, publication date or content hash is shown as null rather than inferred.
  • The project-level evidence grade ranks the strongest source in the entry; it is not a truth score for every claim.
