The Value of an Acre in Elmira

The Argument in One Idea

Urban planner Joe Minicozzi calls it the "miles per gallon" of land: don't ask what a property is worth in total, ask what it's worth per acre. The parcels people assume are the valuable ones — the big supermarket with the big parking lot — usually aren't, and they cost the most public infrastructure to reach.

Two measurements, both taken inside the City of Elmira. Value per acre asks how much taxable value each acre of land carries. Value per foot of frontage asks how much of that value the city gets for each foot of street it has to plow, repave, and run water, sewer, and sidewalk beneath. Compact, walkable Elmira wins on both.

Every comparison here stays inside one city and one assessment roll on purpose. Elmira hasn't had a citywide reassessment in years, so its recorded values can't be compared apples-to-apples with Big Flats or Horseheads, which reassess on different schedules. Keeping the whole analysis inside Elmira removes that problem: every parcel below is measured against its own neighbors on the same roll.

The Supermarket Test

Ask most people which is worth more to the city: a full block of old downtown buildings, or a modern supermarket. Then look at what each one puts on an acre.

$7.9M per acre — 154–184 Main St
downtown apartments, 0.67 acres

$771K per acre — Aldi, 100 Hudson St
supermarket + parking, 2.0 acres

$282K per acre — Wegmans plaza, 1100 Clemens Ctr
store + parking, 18.4 acres

$14.5K per acre — 900 Water St
surface parking, 6.69 acres

A downtown apartment block puts ten times as much assessed value on each acre as Aldi, the most compact of the city's supermarkets, and twenty-eight times as much as the Wegmans plaza. The stores aren't cheap buildings — Wegmans is assessed at $5.2 million. But that value is spread thin across eighteen acres, most of it parking. Value per acre is what exposes that: the same dollars, divided by the land it takes to hold them.

How Much Value Each Acre Carries

Widen from single parcels to every land use in the city. Medians, so a few unusual parcels can't tip the result — and every group is drawn from the same Elmira roll.

The pattern is consistent. Compact downtown rows carry about $1.12 million per acre. Offices and apartments follow. Ordinary single-family homes hold roughly $292,000 — more per acre than warehouses ($154K), far more than parking ($89K), and about fourteen times a lot of vacant land ($21K). The land-hungry, auto-oriented uses that dominate the edges of the city are the ones that carry the least.

The Side of the Ledger Nobody Bills For

Value per acre is only half the story. The other half is what the city spends to reach that acre — and that cost runs in a straight line along the street.

Almost everything the city builds and maintains for a property runs longitudinally past its front: the street itself, the water main, the sanitary and storm sewers, the sidewalk, the plow route, the streetlights. So a fair way to ask "what does the city get back for the infrastructure it maintains?" is to measure value against frontage — assessed value per foot of street the property faces.

On that measure the gap is just as wide. A downtown common-wall block returns about $2,291 of assessed value for every foot of street the city maintains in front of it. A parking lot returns $276. Vacant land returns $68. Buildings that share walls and stack uses put more taxpayers behind each foot of pipe; buildings that sprawl put fewer.

Value per foot of frontage · the infrastructure the city maintains

Compact uses return far more value per foot of city street and pipe

Assessed value ÷ recorded lot frontage, median by land use. Large-footprint supermarkets are left off this chart on purpose — see the note below.

Why frontage, and why supermarkets are excluded Street, water, sewer, and sidewalk costs scale with linear frontage, so value per front foot is a proxy for revenue per unit of infrastructure — not an exact cost accounting. Big-box supermarkets are recorded with little or no frontage in the roll, which would flatter them here (a small measured frontage divided into a large value), even though their parking aprons and access drives consume far more public infrastructure than a storefront. We measure them on value per acre instead, above.

Better House, More Pipe, Less Value Per Acre

The clearest version of the argument needs no commercial parcels at all — just Elmira's single-family homes, one property class on one roll, sorted by lot size.

Put a house on a bigger lot and two things happen at once. Its value spreads over more land, so value per acre falls — from about $318,000 per acre on a typical small lot (0.1–0.2 acre) to about $96,000 on a large one (0.75–1 acre). And it widens, so the city has to maintain more street in front of it: median frontage rises from about 50 feet to about 140 feet.

Here is the part that makes the comparison hard to argue with. The large-lot houses are not cheaper houses being penalized by a per-acre measure — they are better houses. Median assessed value climbs right along with lot size, from $46,000 on the smallest lots to $83,000 on the largest band shown: nearly twice the house. And it still loses. Despite being worth almost double, the large-lot home puts under a third as much value on each acre while making the city plow, repave, pipe, and light nearly three times as much street frontage. More cost, less value, no extra taxpayers to spread it across.

Scope, stated plainly: this is City of Elmira single-family parcels (class 210) on the 2025 roll, from 0.1 up to 1 acre — about 5,300 homes. Lots at or below 0.1 acre are excluded because very small geometries magnify acreage errors. The chart stops at one acre on purpose. Elmira is small and built out, and above an acre only ~34 single-family parcels remain — with a median assessed value of $168,500, 3.6× the typical city home. Their value per acre reads higher for that reason alone. Including them would draw as a reversal of the trend when it is really a change of subject.

How to read it Medians for Elmira property class 210 in each lot-size band; every band shown holds at least 10 homes. Parcels at or below 0.1 acre are excluded because very small geometries magnify acreage and boundary errors. Frontage is a proxy for the linear infrastructure the city maintains per household, not a direct cost figure.

Every city parcel drawn on its real footprint and raised into a bar: height and color both show assessed value per acre. The tall green spikes are downtown; the low red sprawl is everything built around the car.

How to read it:

Taller bars put more assessed value on each acre of land; shorter bars put less.
Color runs red (low) to green (high). Blue parcels are fully tax-exempt on the county roll.
Drag to pan; right-drag, Ctrl-drag, or use two fingers to tilt and rotate. Select a parcel for its address, acreage, and value-per-acre figure.
Every bar comes from Elmira's same 2025 roll, so heights are directly comparable.

Why It Matters for Elmira

On Elmira's own roll, the compact, walkable core carries more value per acre and returns more per foot of infrastructure than the parking lots, supermarkets, and large-lot sprawl around it. That is not a coincidence of one city — it's the pattern Strong Towns and Minicozzi have found in town after town.

Elmira is not short of land; it is short of productive land. When a downtown lot sits vacant or becomes a parking lot, the city doesn't just lose a building — it trades its highest-value-per-acre land for one of its lowest, while still maintaining the same street and pipe in front of it. Every acre pushed toward the low end of these charts is an acre that collects less and costs the same or more to serve.

This is also why zoning and parking rules are a fiscal question, not just an aesthetic one. Rules that mandate parking, forbid mixed use, or set large minimum lots don't only shape how the city looks — they cap how much value each acre is allowed to carry, and lock in the infrastructure the city has to maintain to serve it.

The takeaway, sourced to Elmira's own 2025 roll: compact, connected development earns the city more on every acre and asks less of its street and pipe network per dollar collected. Value per acre and value per foot of frontage are proxies, not a full cost-of-service audit — but they point the same direction, and that direction is toward the kind of place Elmira already has downtown.
