Case study
Two maps of solar in one county: the recorded agreements and the permits that rarely meet them
Jefferson County, Wisconsin publishes every recorded solar farm agreement as a free map layer. This page sets that layer beside the agendas and minutes of the county and its towns, parcel by parcel, to see where the land under agreement and the land under permit meet.
The question In a county that publishes its recorded solar agreements as a map layer, how often do the parcels under agreement meet the parcels that go before a town and the county for a permit?
Beyond the published case
The page Reconstructing a solar project's path through three public offices follows one three-megawatt solar farm in the Town of Palmyra, and finds its agreement recorded with the county 126 days after the county committee approved the project. That is one parcel, read in order. This page asks the county-wide question behind it: across every parcel under a recorded solar agreement in Jefferson County, how many have reached a town or county agenda at all, and do the farms before their towns this year sit on land with an agreement on file?
The question
Jefferson County publishes its recorded solar farm agreements as a map layer: a row for each parcel listing, with the grantee, the recording date and the recorded document. Read alone, it looks like a map of where solar is coming. The agendas and minutes of the county and its towns are a second map, of the projects that actually come before a public body for a permit. Where do the two maps meet, and which projects appear on only one of them?
Why it matters
Reading recorded agreements as site control assumes that the land under agreement is the land where projects are moving. A permit, though, is decided in a town hall and a county committee room, and its conditions, votes and open items are written in their minutes. If the two maps rarely overlap, either one read alone misses part of the county's solar activity, and only one of them says what a project has agreed to do.
What we examined
- The county's map layer: Jefferson County's Solar Farm Agreements layer, every row, queried on October 15, 2026.
- The agenda record: the parcel numbers printed in the agenda items of the county and 16 town, village and city bodies in Jefferson County, from April 2025 to October 2026.
- Town of Oakland: the plan commission's minutes of May 5 and the town board's minutes of July 21, both posted as Word documents.
- Jefferson County: the Planning and Zoning Committee's public hearing minutes of August 20 and its decision minutes of August 31.
- Town of Koshkonong: the town board's agenda headed October 14.
One map layer and five meeting documents from four bodies, all of the documents from 2026.
The record
-
Town of Oakland, Plan Commission
A six-megawatt dual-use solar farm on two parcels zoned A-1, west of Hope Lake Road, is presented to the commission. The scope presented includes decommissioning and the length of the farmland lease.
-
Town of Oakland, Town Board
The board recommends approval of the conditional use 3-1, with all the conditions presented and two added: a Knox box for the fire department, and a landscaping plan for a flower-farming area.
-
Town of Oakland, Town Board
At the same meeting the board approves the stormwater maintenance agreement 4-0, with the plans to be attached. The road agreement is still being worked on.
-
Jefferson County Planning and Zoning Committee, public hearing
The Oakland farm's petition is heard. The minutes give the town's position as approved 3-1 with 29 conditions.
-
Jefferson County Planning and Zoning Committee, decision meeting
On the one agreement parcel with a 2026 county item, in the Town of Jefferson, the committee accepts 4-0 a holding tank for an operations and maintenance building, to stand near the substations of two large solar projects that will share it.
-
Jefferson County Planning and Zoning Committee, decision meeting
CU2217-26, the Oakland farm's conditional use on its two parcels, is approved with conditions by a 3-0 voice vote, one member abstaining.
-
Town of Koshkonong, Town Board (agenda)
The agenda carries a request for a conditional use for a six-megawatt solar electric generation facility on two parcels zoned A-1. It is before the town; no outcome was read.
What we found
The two maps barely touch. On October 15, 2026 the layer held 213 rows on 207 parcels. A row is a parcel listing, not an agreement: the rows cite 148 distinct recorded document numbers, and 101 of them list several. The latest recording date in the layer was September 23, 2026. Joined by parcel number to every agenda item in the record since April 2025, only four of the 207 parcels appear: two in lot rezonings whose items do not mention solar, one in a solar project's own conditional use, and one in a request for an operations building. Most solar and battery items print no parcel number, so four is a floor. The layer can be read in full through the county's map service. Why it is not obvious: a complete, free layer of recorded agreements looks like the county's solar pipeline. Set beside the agenda record, it holds almost nothing a town or the county was asked to decide.
When a large agreement does reach an agenda, it is for a building. The one agreement parcel with a 2026 county item is in the Town of Jefferson. The layer shows its agreement, to a utility-scale developer's land-holding entity, recorded on October 9, 2025, with a term of up to five years. On August 31, 2026 the county committee accepted, 4-0, a holding tank for an operations and maintenance building on that parcel. The minutes place the building near the substations of two large solar projects and say the two will share it. They are on the second page of the decision minutes. Why it is not obvious: on this record, the one meeting between a large recorded agreement and a county decision is about a building's wastewater, not about a solar array.
The farms going through town and county are not in the layer. In the Town of Oakland, a six-megawatt dual-use solar farm on two parcels zoned A-1 was presented to the plan commission on May 5, 2026, and the length of the farmland lease was part of its scope. That is in the commission's minutes. On July 21 the town board recommended approval 3-1 with all the conditions presented, adding a Knox box for the fire department and a landscaping plan for a flower-farming area. At the same meeting it approved the stormwater maintenance agreement 4-0, while the road agreement was still being worked on. Both votes are in the board's minutes.
The county's August 20 hearing minutes give the town's position as approved 3-1 with 29 conditions. The line is in the hearing minutes. On August 31 the committee approved the conditional use, CU2217-26, by a 3-0 voice vote with one member abstaining. That vote is on the fourth page of the decision minutes.
In the Town of Koshkonong, a second request, for a six-megawatt solar electric generation facility on two parcels, is on the town board's agenda. As of October 15, none of the four parcels of the two farms is in the layer. Why it is not obvious: the farmland lease was part of what the town heard in May, yet the county's map of recorded agreements shows nothing on those parcels, 45 days after the county's approval. On this record the lease and the permit surface in different places, and a layer of recordings shows only one of them.
Only the permit map carries the terms. For each parcel, the layer holds a grantee, a recording date, a document number and sometimes a term. What the Oakland board added, how its vote split, and which agreement was still open are written only in the town's minutes and the county's. Why it is not obvious: a map of agreements suggests that the paper behind a project is on file. The conditions a farm must meet are not in it; they are in the minutes.
In this county the recorded-agreement layer and the agenda record are two maps of solar that rarely meet, and only the agenda record says what a town and the county asked of a project.
What the record does not show
- The join is by parcel number as printed in agenda items. Most of the record's Jefferson solar and battery items print no parcel number and cannot be joined, so four of 207 is a floor, not a count.
- Whether agreements on the Oakland or Koshkonong parcels exist unrecorded, or are recorded under another document type, is not known; the Register of Deeds index was not searched. An unrecorded lease or option does not appear in the layer.
- A row in the layer is a parcel listing, not an agreement, and the layer gives recording dates, not signing dates.
- The four overlapping parcels were matched by parcel number; their agenda items were not re-read one by one.
- The Koshkonong agenda is headed October 14, 2026, but its notice gives the meeting as Wednesday, October 21. Its outcome was not read; the request is before its town, not approved or denied.
- The layer was read once, on October 15, 2026. Agreements recorded since then are not counted.
- One county that publishes such a layer, read closely; not a survey of other counties.
How it was done
The county's layer was queried directly from its public map service and joined by parcel number to a record of agenda items read from the county's and the towns' postings. The Oakland minutes were read from their Word files, the county's and Koshkonong's from their PDFs. Landowners and officials appear by role and place, and each status is given as the record leaves it.
