Rezoning petitions in Somerset: the change or mistake rule

Rezoning petitions in Somerset: the change or mistake rule

In January 2020, Gary King filed a petition to rezone Tax Map 23, Grid 3, Parcel 233 from Residential (R-2) to Agricultural Residential (AR) — not to build houses, but to put an agricultural conservation easement on the property through the Maryland Agricultural Land Preservation Foundation. The land was working farmland. The zoning said otherwise. That gap between what the land physically is and what the map says it is sits at the center of every piecemeal rezoning petition in Maryland, and the legal mechanism for closing it is called the change or mistake rule.

The rule is a load-bearing structure in Maryland land use law. It governs every individual rezoning request — every single parcel, every two-acre lot, every waterfront property line that wants to switch from one conventional Euclidean zone to another. It does not apply to comprehensive county-wide rezonings, floating zones, or overlay districts. Somerset County redrew its entire zoning map under Ordinance No. 1144 in August 2019, replacing Ordinance No. 741 from 2001. After that comprehensive rezoning, every piecemeal petition filed since gets measured against the change or mistake rule. Property owners who want to challenge their zoning classification need to understand what the rule actually requires — and, more importantly, what it does not.

The legal foundation: what the change or mistake rule actually says

The change or mistake rule is a Maryland judicial doctrine that has been baked into the practical operation of every county's zoning ordinance. Under it, a property owner who wants to rezone a single parcel — what land use lawyers call a "piecemeal" or "spot" rezoning — has to make an affirmative showing. They must prove either that there was a mistake in the original zoning of the property, or that the character of the surrounding neighborhood has changed substantially since the last comprehensive rezoning.

This is not a polite suggestion. It is a legal hurdle that higher courts have used to overturn county rezoning decisions that came in without proper findings. The Maryland appellate courts treat the rule as a check on the legislative power of county councils and boards of county commissioners — a way to prevent individual property owners from using the rezoning process to override the comprehensive planning work the county has already done.

Not every zoning action triggers the rule. The table below sorts out what does and does not:

Somerset County's 2019 comprehensive rezoning under Ordinance No. 1144 sat outside the rule entirely. Every petition that has come in since — including the King and J&J Agriculture cases — has had to clear the change or mistake bar.

Several core principles follow from this:

• The burden of proof sits on the applicant. Not the county, not the neighbors, not the planning commission. The person filing the petition has to put forward evidence — typically through a presentation at the Planning Commission public hearing — that satisfies one of the two prongs.
• The rule is a jurisdictional filter, not a planning preference. The Planning Commission and the Board of County Commissioners cannot waive it. If an applicant cannot make a change or mistake showing, the petition has to be denied or tabled — no matter how reasonable the proposed new zone might otherwise be.
• The rule looks backward at the existing zoning, not forward at the proposed new zone. The mistake prong asks whether the original zoning was wrong at the time it was applied. The change prong asks whether the neighborhood has moved so far from the original zoning's assumptions that the designation no longer fits. Neither prong requires the county to pre-approve the destination zone.

The change or mistake rule is a gate, not a guarantee. Proving it gets you through the front door. It does not lock the door behind you.

Defining the burden of proof: change versus mistake

The two prongs of the rule look similar but operate differently in practice. They require different kinds of evidence, different documentation, and different analytical work.

The "mistake" prong is a backward-looking question. The property owner must show that something erroneous happened during the comprehensive rezoning process — that the zoning designation assigned to the parcel does not match the land's actual physical characteristics, its historical use, its soils, or its location relative to infrastructure. A property classified as residential but sitting in a floodplain with no road access and no drainage capacity would qualify. A property classified as R-2 in the middle of a platted residential subdivision with all utilities available would not.

In Somerset County, mistake claims typically come in two flavors. The first is straightforward cartographic error — the wrong designation applied to the wrong parcel during the map redraw. The second is more substantive — the land's physical reality (wetlands, soil type, drainage, road access) was not properly considered when the comprehensive plan was scored. The Gary King petition in 2020 was essentially a mistake case: the 100.38-acre parcel was actively farmed, and the R-2 designation appeared to be a misclassification given the land's actual use and the county's agricultural preservation goals.

The "change" prong is a forward-looking question. The applicant must identify a defined neighborhood, show that substantial physical, demographic, or infrastructural changes have occurred within that neighborhood, and demonstrate that those changes have altered the neighborhood's character to the point where the existing zoning no longer makes sense.

The change prong is harder to prove. It requires three analytical steps:

1. Define the neighborhood's geographic boundaries. This is not a line drawn on a zoning map. It is a physical area that shares common characteristics — road access, drainage patterns, land use, development history. In rural Somerset County, neighborhoods may be defined by watersheds, road networks, or agricultural districts. In transition zones near municipalities like Princess Anne or Crisfield, neighborhoods may be defined by sewer service areas, historic subdivision plats, or the edge of a town growth boundary.

2. Document substantial changes since the last comprehensive rezoning. What has been built, paved, drained, subdivided, or abandoned? What has changed in traffic counts, school enrollment, utility connections, or land cover? A single new subdivision is not automatically a substantial change. Aggregate shifts in land use over multiple years are.

3. Connect the changes to the zoning question. This is the step most often missed. The applicant has to show that the new neighborhood character is incompatible with the existing zoning — that a Residential-2 designation, for example, no longer fits a neighborhood that has been steadily converting to agricultural use or moving into conservation easement.

The change or mistake rule does not let an applicant pick whichever prong is easier. Both prongs require affirmative evidence, and the Planning Commission and the Board of County Commissioners are entitled to weigh that evidence against the county's own planning documents.

Navigating neighborhood boundaries and character shifts

The hardest part of any change-or-mistake petition is not the legal standard. It is the geography. Zoning happens on a map, but the change or mistake rule operates on the physical landscape. The question "what is the neighborhood?" has to be answered with drainage basins, road networks, soil types, and historical land use — not with political boundaries or parcel lines.

In Somerset County, this is particularly tricky because the county is rural, the population is small, and the land use pattern is heavily agricultural. The county's zoning map divides the landscape into broad districts, but the actual land use pattern is defined by working farms, timber tracts, tidal wetlands, and scattered residential parcels along county roads. A "neighborhood" in this context might be a stretch of Route 413, a section of the Manokin River watershed, or a cluster of parcels around a crossroads. Defining that neighborhood with enough precision to support a rezoning petition requires local knowledge, survey work, and often the kind of physical inspection that a planner or engineer — not a lawyer — is best equipped to provide.

Common failures in this area include:

• Defining the neighborhood too broadly. A petition that claims the entire southern half of Somerset County as a neighborhood will not survive scrutiny. The neighborhood has to be a specific, bounded area with shared physical characteristics.
• Defining the neighborhood too narrowly. A petition that claims the four adjacent parcels will be challenged as a spot rezoning in disguise. The neighborhood has to be large enough to represent a real planning unit.
• Ignoring drainage and infrastructure. An area may have changed in land use, but if the drainage capacity, road access, and utility infrastructure have not changed, the existing zoning may still be appropriate.
• Failing to document the change with hard data. Anecdotal claims about neighborhood transformation will not substitute for traffic counts, building permits, utility hookups, and land use inventories.

Discretionary authority: why approval is never guaranteed

This is the single most misunderstood part of the change or mistake rule, and it is the point that trips up most property owners who file piecemeal rezoning petitions.

Proving a change or mistake does not legally compel the Board of County Commissioners to approve the rezoning. It only permits them to do so, and only if the proposed new zone is appropriate, logical, and consistent with the county's Comprehensive Plan.

The Boards of Somerset County — both the Planning Commission, which makes a recommendation, and the Board of County Commissioners, which makes the final decision — retain discretionary authority. Their job is not to rubber-stamp a petition that has cleared the change or mistake threshold. Their job is to weigh the petition against the Comprehensive Plan, the county's growth policies, the water and sewer capacity, the agricultural preservation goals, and the character of the surrounding area.

The procedural sequence is fixed:

1. Filing. The petitioner submits a rezoning application to the Somerset County Department of Technical and Community Services at 11916 Somerset Avenue, Suite 211, Princess Anne.

2. Planning Commission review. The Planning Commission holds a public hearing, takes evidence on the change or mistake claim, and votes on a recommendation to the Board of County Commissioners.

3. Board of County Commissioners hearing. The Board holds a separate public hearing and makes the final decision. The Board may approve, deny, or send the petition back to the Planning Commission for further review.

4. Compliance with the Comprehensive Plan. Even if the Board approves, the rezoning must be consistent with the Comprehensive Plan. If the proposed new zone is inconsistent with the Plan's growth elements, agricultural preservation goals, or critical area provisions, the rezoning may be challenged and overturned.

A piecemeal rezoning is a discretionary act. The applicant has to clear the change or mistake bar, and then the governing body has to agree that the change is consistent with the county's own planning. Both doors have to open.

Lessons from recent Somerset County rezoning petitions

The two most visible recent piecemeal rezoning requests in Somerset County illustrate how the rule operates in practice.

The Gary King petition (2020). Tax Map 23, Grid 3, Parcel 233 — 100.38 acres — was filed for rezoning from R-2 to AR on January 21, 2020. The stated purpose was to allow the property to be placed under a MALPF conservation easement. The petition was framed as a mistake case: the land was being actively farmed, and the residential zoning appeared to be a misclassification given the land's actual use and the county's agricultural preservation priorities. The petition highlighted the gap between the Comprehensive Plan's land preservation goals and a zoning map that classified productive farmland as residential. This case is a textbook example of the kind of mistake claim the rule is designed to address — a clear inconsistency between the land's physical reality and its zoning designation.

The J&J Agriculture petition (2020). Map 23, Grid 3, Parcel 594 (A, B, C, E) was the subject of a public hearing before the Somerset County Planning Commission on August 6, 2020. The petition sought to rezone the property from Maritime Residential Commercial (MRC) to Agricultural Residential (AR), again based on a claim of mistake. The hearing was held, testimony was taken, and the petition was subsequently tabled. The case is notable because it shows the limits of the process: even when a property owner presents a change or mistake case, the Planning Commission is not obligated to approve it, and tabling the petition is a way to ask for more information without taking a final position.

The practical takeaway from these cases is not that the change or mistake rule is broken. It is that the rule does exactly what it is supposed to do. It forces property owners to confront the physical reality of their land, the planning reality of the county's Comprehensive Plan, and the procedural reality of a public hearing process. A petition that clears the change or mistake hurdle has done real work. It has produced evidence, gone through public review, and survived scrutiny. But it has not bought the rezoning.

What this means for property owners and the county

For property owners in Somerset County, the change or mistake rule is the cost of doing business in a zoning system that takes comprehensive planning seriously. A county that did not have the rule would be vulnerable to spot rezonings — individual parcels flipped out of one zone and into another every time a property owner found a more profitable use. The rule prevents that. It also means that the burden of proof sits squarely on the applicant, and that the process is not a bureaucratic formality but a real legal test.

For the county, the rule is a tool — but only if it is used consistently. Somerset County's Planning Commission and Board of County Commissioners have to weigh every petition against the Comprehensive Plan, the agricultural preservation goals, and the physical infrastructure of the area. A change or mistake ruling that ignores the Plan's growth elements or the drainage capacity of the surrounding area is an invitation to litigation. The Planning Commission in particular has a responsibility to develop a clear record at the public hearing — findings of fact on the change or mistake claim, findings on the Comprehensive Plan consistency, and findings on the proposed zone's appropriateness.

The practical steps for anyone considering a piecemeal rezoning in Somerset County are straightforward:

• Get the land right. Before filing the petition, survey the property, document the soils, the drainage, the road access, and the historical land use. The change or mistake case stands on the physical character of the land.
• Define the neighborhood. Use a geographic area that makes sense — a watershed, a road segment, a defined agricultural district. Define it with boundaries that can be defended at the public hearing.
• Document the change or mistake. Compile the evidence — building permits, land use inventories, aerial photography, utility records, traffic counts. Anecdote is not enough.
• Confirm the Comprehensive Plan consistency. Before filing, check that the proposed new zone is consistent with the Comprehensive Plan's growth elements, agricultural preservation goals, and critical area provisions. If it is not, the Board of County Commissioners has legal grounds to deny the petition even if the change or mistake claim is solid.
• Prepare for the public hearing. The Planning Commission hearing and the Board of County Commissioners hearing are separate proceedings. Both require sworn testimony, documentary evidence, and the ability to defend the petition against hostile questions from neighbors, planning staff, and the commissioners.

The change or mistake rule is not a barrier to reasonable land use change. It is a filter. It separates the petitions that have a genuine planning basis from the petitions that are just an attempt to flip a parcel for short-term gain. Anyone who can clear the filter has done the work. Whether the Board of County Commissioners agrees that the rezoning is appropriate is a separate question — and a legitimate one.
