1. Inspect two worked rows.
The fictional example shows the actual columns, document mismatches and open decisions for this task.
Iowa / Historical site evidence
Historical activity-to-program-file register
Build an editable historical activity-to-program-file register, with source locators, open decisions and a file your team can review.
Iowa DNR record and brownfield guidance checked September 30, 2026. The method does not designate a property as contaminated, clean or eligible for assistance.

One working file to take back to the team
Connect the records. Preserve the exceptions.
2. Build your own register.
Start blank, edit the cells and add as many records as the review needs, up to 200 rows per file.
3. Export and assign review.
Download the register as CSV or a readable text file, including source context and edition. The companion below helps organize the next document requests.
Your editable work product
Historical activity-to-program-file register
Name your Iowa research file, replace the fictional observations with your own references, and resolve each item before relying on the historical use and environmental files conclusion.

- Activity timeline
- Program coverage
- Underlying file
- Proposed-use scope
How to use the table
- Start one row for each operating name / period. Keep distinct documents and competing versions separate.
- Connect program / search scope to the same row. Record a document locator and retain any mismatch instead of silently choosing a value.
- Complete reuse question with the decision still open and the person who should review it. Export the register with the source documents.
Start with a blank row or load the fictional example.
Your entries remain in this page only. Download or copy before leaving; nothing is automatically saved or fetched.
Add one record or comparison per row. Leave unknown facts blank or name the missing document. Scroll the table horizontally on a small screen. Each cell accepts up to 2,000 characters.

Take the working file with you
You can export this blank table before filling it in elsewhere. The export includes the kit edition, row provenance and method references. Method references do not verify your property.
CSV copy fallback
If file saving is blocked, copy this into a UTF-8 .csv file.
This table does not upload documents, search records, run an AI model or confirm source facts. The next-request worksheet below is a separate companion; entries are not copied between the two tools.
Companion: document requests
Turn unresolved items into a review handoff.
This separate four-item sheet helps organize supporting requests. It does not copy or analyze the entries in your register.
Open, work, export
Make the next decision easier to review.
Name your Iowa research file, replace the fictional observations with your own references, and resolve each item before relying on the historical use and environmental files conclusion.
Method and source context
Keep the evidence with the worksheet.
These references explain the method. They do not verify facts about your property. Your export keeps their scope separate from the document references you enter.

Facility discovery by location, identifier and program, with active and all-facility options.

Brownfield Redevelopment
Iowa Department of Natural Resources · Checked 2026-09-30
Brownfield guidance and distinctions between contaminated-site and petroleum-tank records.
- A database listing is not necessarily a current concern, and unlisted or older activity may require separate investigation.
What this edition does
- The worked example is fictional and does not describe a researched property.
- The worksheet organizes supplied evidence; it does not fetch records, verify a property or calculate investment returns.
