What does the Ann Arbor MI 311 data include?

2 tables: service requests (one row per service request) and request types (one row per request type the city accepts).

Do I need an account with Ann Arbor MI 311?

No. The data is public, so there is nothing to sign up for and nothing to paste in.

How fresh is the data?

As fresh as your schedule: daily by default, or weekly or monthly. Schedules as often as every 15 minutes are on the Enterprise plan.

Will running it again create duplicate rows?

No. Each row is stored once, by its key: when a run reads a row that is already there, it replaces that copy instead of adding a second one.

Do I need to write code?

No. Ingest builds, runs and maintains the connector. Someone with access to your warehouse connects it once, following a short guide.

What you get

Table	Each row is
Service requests `service_requests`	One service request
Request types `services`	One request type the city accepts

Good to know

Service requests: The first run loads the last 30 days. After that, each run keeps the last 30 days current, re-reading a day once its copy is at least 7 days old. Older requests keep the values they had when last read.
Request types: Re-read in full at most once a day. Rows that changed are updated, and rows the source removes stay in your table.

Resources

Resource	Status	Plan	Write	Primary key	Overrides
`service_requests` Public requests from the selected creation-history period, defaulting to the last 30 completed days. Completed days within the selected horizon become eligible for refresh after seven days by default; later edits are captured when their creation day is read again. Increase lookback_days to include older creation days. Requests outside the horizon and records removed from the source retain their last synced values. Requests are not filtered by membership in the current service-type catalog. Older completed days wait longer between reads, becoming eligible again only after the longer of the refresh interval and a twentieth of their age at their last read (with the default interval, a day read at 280 days old waits 14 days).	beta	window	merge	`service_request_id`	lookback_days, staleness_days
`services` Public service types returned by the Ann Arbor SeeClickFix catalog. The catalog becomes eligible for refresh after one day and merges by service code; previously synced types remain if removed from the source. It does not filter the requests collection.	beta	staleness	merge	`service_code`	-
