What the data contains

Baltimore County's Department of Planning maps the extents of the community associations it works with, including homeowners' and condominium associations, civic and improvement associations and community councils, and publishes the layer on the County's open data portal and ArcGIS REST services. Each run reads the whole layer (up to 500 associations, in pages of 100) and returns one record per association: the County's global ID, association name, whether the association is active, the date it was mapped and the time the County last edited the record. A monitor reports associations added to or removed from the layer, renamed or marked inactive. The County links the layer to a separate Planning contacts database; neither that link ID nor any contact information is requested, editor user names are not read, and map geometry is not downloaded.

Fields and types

Every record has these fields. The key field global_id identifies a record across runs, so changes are reported field by field.

Sample output

The first 5 of 231 records from SourceFinch's own run on October 3, 2026, exactly as delivered.

Evidence behind every value

• Each run keeps the publisher's exact response, hashed with SHA-256. This sample came from a response with hash f24456c33ec418079419a65f23e4a8f6f273b7ec8f9fd361734002f7cd92a8a9.
• Every value records where it came from in that response: a JSON Pointer into the retained capture.
• Each run gets a signed manifest (Ed25519) timestamped by an RFC 3161 authority: this run's manifest hash is a4a495a4703380204ee0a41f5d3ebc9adcfa34abdd48b97f6bb14ce6a8d59662, timestamped October 3, 2026.
• The compliance state at capture is recorded with the evidence: robots.txt hash and verdict, AI-preference signals, crawler identity and the usage rights below.
• Download any run as an evidence bundle (WACZ) and check it offline, without trusting SourceFinch: sourcefinch verify-bundle run.wacz.

Terms posture and usage rights

Baltimore County publishes the Community Associations layer on its open data portal and ArcGIS REST service without registration. Its warranty and disclaimer state the data may contain errors, that the County disclaims all warranties and liability, and that the user assumes the risk of relying on it. The GIS host serves no robots.txt (HTTP 404), which RFC 9309 treats as allowing access.

Source: Baltimore County, Maryland, Department of Planning, Community Associations layer. Baltimore County does not warrant the accuracy or reliability of the data.

Usage rights travel with every record SourceFinch delivers (API, exports, webhooks and evidence bundles). They are our documented understanding of the publisher's stated terms, not legal advice.

Pricing

Each check is one run, whatever the number of records, and failed runs are free. On its default daily schedule this source uses about 30 runs a month, which fits the Free plan's 300 runs. It uses HTTP acquisition, so no browser runs are needed. See plans.
