ZIP code 43137: Harrison Township and Lockbourne

Drinking-water compliance

A health-based violation is a contaminant above its limit or a treatment rule not followed; monitoring, reporting and public-notice violations are paperwork. Lead is the 90th-percentile result across sampled homes, not a reading at any one tap.

Byproducts and contaminants

TTHM

33.4 µg/L yearly mean in 2019, the last year in the file (limit 80); worst yearly mean 51.3, highest single sample 111; 512 samples from 2012 to 2019

HAA5

19.3 µg/L yearly mean in the last year sampled (limit 60); worst yearly mean 36.5, highest sample 65.2; 512 samples

Plants

Columbus Public Water System runs 3 plants and EPA's file lumps their entry-point samples under one system, so the nitrate, arsenic, radioactivity, solvent, farm-chemical and metal rows cover all 3, not only Parsons Avenue Water Plant (South Well Field), which serves this ZIP; a sample over a limit may be from another plant

Nitrate

highest of 232 samples was 12.5 mg/L as nitrogen (2015; limit 10), 12 samples over the limit; 3.6 in 2019, the last year sampled. Nitrate above 10 is unsafe for infants

Arsenic

not detected in 18 samples (limit 10)

Solvents and fuels

benzene, carbon tetrachloride, 1,2-dichloroethane, trichloroethylene, tetrachloroethylene, vinyl chloride not detected in 18 samples

Bacteria

4 of 30,122 routine tap samples (0.01%) tested positive for total coliform in 2012 to 2019, 0 of 3,897 in 2019; E. coli never found in the 4 tap samples tested for it. Coliform itself is a warning sign; E. coli means sewage or manure reached the water

Farm chemicals

atrazine in 21 of 57 samples, highest 2.8 µg/L (limit 3); alachlor in 6 of 57 samples, highest 0.37 µg/L (limit 2); 2,4-D not detected in 2 samples

Metals

barium in 11 of 18 samples, highest 17 µg/L (limit 2,000); chromium, cadmium, mercury, selenium, thallium not detected in 18 samples

EPA's file stops at 2019; Ohio EPA's Drinking Water Watch has newer results. Byproducts are judged on running yearly averages at each sampling site, so one high sample is not a violation. Nitrate and arsenic are measured where water enters the pipes.

PFAS

UCMR 5, all plants

12 samples in 2024 at the entry point to the distribution system: PFHxA 18.2, PFBA 17, PFPeA 14.2 ng/L

Sources

The system reported a known PFAS source near its supply

Ohio EPA 2020

3 plants tested (latest 2020-10): nothing detected for the six PFAS tested

Ohio EPA latest

3 plants sampled by Ohio EPA, most recently 2020-10 (Ohio EPA statewide sampling status map)

Firefighting foam: 7 fire departments or other holders in Franklin County registered 3,800 gallons of PFAS-based AFFF foam with Ohio EPA, 3,165 gallons in opened containers; the state is collecting it for disposal so it is never sprayed again.

Lithium: not detected in 10 UCMR 5 samples at Columbus Public Water System (the method reports from 9 µg/L). Lithium is unregulated; EPA's draft health reference level is 10 µg/L, and it occurs naturally in deep groundwater, so well systems in the northwest run highest.

PFAS are the forever chemicals from firefighting foam, plating shops and non-stick coatings. One sample above 4 ng/L is not a violation; compliance is judged on running annual averages, and systems are adding carbon filters ahead of the 2029 deadline. Results are for water leaving the plant, not your tap.

Lead at the tap

Latest period

1.2 ppb in the sampling period ending 2023-12

Record

3 sampling periods since 2016, none above 10 ppb

Service lines

288,462 inventoried: 25,155 lead, 8,093 galvanized needing replacement, 65,266 unknown, 189,948 not lead (reported all required service line types)

Children: the Ohio Department of Health lists this ZIP as high-risk for childhood lead exposure, mostly from old paint and soil, so every child living here should get a blood lead test at ages 1 and 2 (Medicaid covers it, and doctors are required to order it).

Housing age: 10% of the homes here were built before 1960 and 3% before 1940, when lead service lines, lead solder and lead paint were common; 43% predate 1980 (Census ACS 2020 to 2024).

Systems sample taps in the homes most likely to have lead pipes or solder; the 90th-percentile figure means nine in ten sampled homes were at or below it. Lead comes from the service line and the house plumbing, not the source water, so a low system result does not clear an old house. The action level drops from 15 to 10 ppb in 2027, and every lead line must be replaced within ten years of that.

Fluoride and treatment

Treatment on file: corrosion control, coagulation and settling, chlorine disinfection, iron and manganese removal, ion-exchange softening, lime softening, ozone, powdered activated carbon, sand or media filtration, ultraviolet disinfection.

Measured fluoride: 0.97 mg/L on average at the plant's entry points in 2019 (in the range dentists aim for); samples ran from 0.82 to 1.01 mg/L across 18 samples in 2012 to 2019 (EPA compliance monitoring). Natural fluoride in Ohio well water runs from a trace to over 2 mg/L in parts of the northwest.

The health department counts 99.9% of Franklin County residents on community water as receiving fluoridated water.

Ohio law (ORC 6109.20, 1969) makes systems serving 5,000 or more people fluoridate unless the water already carries 0.8 mg/L naturally or the community exempted itself by ordinance or referendum in the months after the law passed; smaller systems choose for themselves. The treatment list is what each system registered with EPA and can lag a plant upgrade.

Algal toxins

Raw water

18 detections at the intake across 6 bloom seasons (2016 to 2026); highest since 2024 0.29 µg/L

Treated water

2 detections, highest 0.26 µg/L (2025-10), below the 0.3 µg/L advisory level

Monitoring

1,604 samples from 2016 to 2026, latest 2026-08-24

Raw-water readings show what the plant has to remove; any detection at the intake triggers weekly paired raw and treated-water testing until two clean weeks, and carbon, ozone or chlorine destroys the toxin in nearly every case. The ten-day advisory levels for treated water are 0.3 µg/L for children under six and 1.6 µg/L for everyone else. Since November 2022 the bloom season runs June through November (sampling continues into early December), with treated water tested every two weeks the rest of the year; the 2016 to 2022 rule monitored year-round and stepped testing up to three days a week when raw water passed 5 µg/L.

23% of this ZIP lies inside Ohio EPA source water protection areas for 5 public water systems (Columbus Public Water System, Commercial Point Village, Caravan Village Mhp), 6% inside inner management zones, the ground a well draws from within a year; the largest, Columbus Public Water System, is rated high susceptibility in a buried valley setting

Geology

85% of the ZIP is a sensitive geologic setting, where thin or sandy cover leaves the aquifer open to what soaks in from the surface; nearest verified sinkhole 13.8 mi away (Ohio EPA and ODNR Geological Survey)

Injection wells

103 Class V injection wells on Ohio EPA's books inside this ZIP (101 active): 5 large septic, 95 cleanup injection, 2 vehicle waste, 1 other; these put fluids underground above or into drinking water aquifers

Water table

FR-126 M13 monitoring well (USGS), 1.8 mi away: water 12.9 ft below ground on 2026-06-30; averaged 12.4 ft in 2015 to 2019 and 14.7 ft over the latest year, so the table is running about 2.3 ft lower; range 6.2 to 17.2 ft over 3,617 readings since 2015

Nitrate risk

EPA researchers put the chance that a public water system in the Town of Lockbourne-Big Walnut Creek subwatershed exceeds the nitrate limit at 30% if it draws on groundwater and 65% if it draws on rivers or lakes, judged from land use, geology and past results (EnviroAtlas nitrate violation index; the typical Ohio subwatershed scores 23% for groundwater and 39% for surface water)

Quality monitoring

Ohio EPA's nearest ambient groundwater monitoring well is Columbus South Wellfield (Franklin County), 2.8 mi away: 102 ft deep in sand and gravel (Scioto River aquifer); wells there yield over 500 gallons a minute; on standby. 15 active wells within 15 mi

Vulnerability rates how easily a spill at the surface reaches the aquifer, not whether anything has. Well logs include abandoned and replaced wells, so counts overstate wells in use; a private well owner is the only one who tests it.

4 of the last 12 quarters with a violation; currently in violation (not significant); 6 effluent limit exceedances in 3 years

Other discharge permits: 9 facilities inside this ZIP other than sewage plants hold a Clean Water Act permit (factories, water plants, quarries, package plants, storm water); 1 in significant noncompliance; 14 facility-quarters with a violation in the last three years; largest: Buckeye Trails - L (in significant noncompliance).

Sewage sludge: 53 farm fields covering 2,083 acres inside this ZIP are permitted for spreading treated biosolids, mostly from Columbus Southerly Wwtp (1,136 acres), Jackson Pike Wwtp (619 acres), Commercial Point Wwtp (246 acres); 1 more retired (Ohio EPA). Biosolids carry nutrients and, increasingly under scrutiny, PFAS.

Sludge source: 2 permitted biosolids generators are inside this ZIP; nearest Columbus Southerly WWTP, 1.1 mi away (a major plant); 10 within 10 miles (Ohio EPA).

State water loans: 34 projects inside this ZIP have borrowed $855.5 million from Ohio EPA's revolving loan funds since 2015 (28 sewer, storm water and runoff projects for $807.5 million; 4 drinking water projects for $45.4 million). Largest: SWWTP Organics Receiving & Bioenergy Fac. CIP 650353-100007 (Columbus, 2025, $479.1 million); latest: SWWTP Power Systems Upgrades and Safety Imp 650357-100101 (Columbus, 2026, $17.8 million). Below-market loans are how most Ohio treatment plants and water mains get rebuilt.

Sewer planning: this ZIP falls in the Columbus City Community-level FPA; 67% of it is assigned to City of Columbus as the designated sewage management agency under Ohio's Clean Water Act section 208 plan (specific prescriptions); 5 agencies share the ZIP. The 208 plan decides who may build and extend sewers.

Stormwater: 23% of this ZIP lies inside Ohio EPA's regulated MS4 areas, mostly the City of Columbus storm sewer system (9 permit holders overlap the ZIP); the towns, townships and counties that own those storm sewers hold a stormwater permit and must control what runs off streets and parking lots (2020 to 2030 designation). 7 sites with an address in this ZIP hold their own industrial stormwater permits (Lockbourne Ag Center Inc, Cardinal Truss & Components, Amazon Services - Soh3 and others) (EPA Facility Finder).

Plants inside this ZIP: Southerly Wastewater Treatment Plant (114 MGD, major, CSO); Village of Commerical Point Wwtp (1.43 MGD).

Where a home's sewage actually goes depends on the sewer district, and rural homes are on septic systems the county health department permits; the nearest plant is a proxy. Violations range from paperwork to raw discharges.

Watersheds here: Grove Run-Scioto River (not supporting); Town of Lockbourne-Alum Creek (fully supporting).

Fish advisories (Ohio EPA): Scioto River (Greenlawn Dam (Columbus) to U.S. Route 35 (Chillicothe)): saugeye one meal a month, flathead catfish one meal a month, common carp one meal a month and 1 more species (PCBs, mercury). Statewide, every other fish is one meal a week because of mercury.

Nearest stream assessment (Ohio EPA): Scioto R. 0.45 Mi. Upst. Big Walnut Creek on the Scioto River, 1.8 mi away, draining 1,709 square miles: full attainment of its warmwater use; fish IBI 52 of 60 (2009); bug ICI 32 of 60 (2009); habitat QHEI 73 of 100. 6 assessed sites inside the ZIP, 5 within 3 miles, 59 within 10. Scores above about 40 (IBI), 36 (ICI) and 60 (QHEI) mean a healthy warmwater stream.

Stream designations (Ohio EPA water quality standards): 23.3 miles of designated streams cross this ZIP: 14.1 mi exceptional warmwater habitat, 9.2 mi warmwater habitat. Nearest specially protected stream: the Big Walnut creek (Rocky fork (RM 28.3) to the mouth), 0.2 mi away, a Superior High Quality Water; 67% of the ZIP lies within a mile of such a stream, where new discharges face the strictest antidegradation review. Exceptional and coldwater streams are the state's healthiest; modified and limited-resource waters are channelized or ditched.

Proposed for 2026: Ohio EPA's pending water quality standards rewrite would add 11.1 miles of stream in this ZIP to the antidegradation tiers: the Scioto River as Outstanding State Water for recreation (Mill creek above O'Shaughnessy reservoir (RM 155.4) to the mouth). Listing raises the bar for any new or expanded discharge.

PFAS in the river (Ohio EPA large river survey): at Scioto R. At Shadeville @ St. Rt. 665, 2.1 mi away, the water carried 100.51 ng/L of total PFAS (PFOA 6.1, PFOS 2.9 ng/L); fish fillets held 24.51 ng/g in bluegill and 19.18 ng/g in catfish (PFOS 7.1 in bluegill). Drinking water limits are 4 ng/L for PFOA and PFOS; river water is not drinking water, but treatment plants that draw from it start from these numbers.

Farm chemicals (USGS estimate, 2018): farms in Franklin County used about 55 metric tons of pesticide active ingredient, 102 kg per square mile, 59th of Ohio's 88 counties. Largest: glyphosate 21 t, atrazine 7 t, metolachlor 7 t, acetochlor 3 t, 2,4-D 2 t. Atrazine, the corn herbicide, is the pesticide that most often shows up in Ohio tap water after spring rains; this county used 7 t of it.

Farms (2022 Census of Agriculture): 372 farms work 48,728 acres of Franklin County, with 12% of its land in cropland, 131 acres to a farm. 293 cattle, 3,404 laying hens, 688 broilers, 46 turkeys; 11,727 acres of corn and 20,845 of soybeans. Sales $72 million, 22% from animals and animal products. Manure and fertilizer from farms like these carry the phosphorus and nitrogen behind Ohio's algae and nitrate problems; withheld figures protect individual farms.

A watershed unit fails when any sampled stream in it fails; ditches in flat farm country fail on habitat and nutrients, city creeks on bacteria and sediment. Ohio's own report is at epa.ohio.gov; the EPA link on each unit's report page has the sampling detail.

Survey counts are permits issued, not houses finished, and cover new residential construction only: additions, remodels, garages and commercial buildings are not in the survey. Values are the applicants' estimates. Where a city runs the building department for its township neighbours, the city's figure covers them too.

Zillow's typical home value here is $319K (2026-07), up 1% over the year, up 21% over five years and up 83% over ten. Typical asking rent $1,530 a month (2026-07).

On the market (Realtor.com, August 2026): median asking price $675,000, $248 per square foot for a typical 1,960 sq ft listing; 18 active listings, 0 new this month; listings spend a median 50 days on the market; 14% of listings have cut their price. Realtor.com flags this ZIP's figures this month as low quality (18 active listings), so the asking price is not a market median.

The index follows the same houses through repeat sales and refinance appraisals on conforming mortgages, so it measures price change rather than the price level (the Homes card has the median value). Consumer prices rose about 36% from 2015 to 2025, so a gain under 36% is a loss in real terms.

School district income tax

Teays Valley Local 1.5% (42% of residents), Hamilton Local none (30% of residents), Columbus City none (16% of residents), South-Western City none (11% of residents). Voted by the district and collected with the state income tax.

Sales tax

8% combined rate in Franklin County: Ohio's 5.75% plus county and transit levies; this ZIP straddles counties or transit districts, so the rate depends on the address.

A mill is $1 per $1,000 of taxable value, and taxable value is 35% of market value. Effective rates fall as values rise because Ohio holds most voted levies to the dollars first approved. County, municipal or township, library, park and vocational-school levies are added on the same bill and are not counted here.

Columbus Division of Power, the city's own utility, also serves customers inside the city limits here. The two territories interleave block by block, so the split is not mapped.

South Central Power Company outages, 2024: the average customer lost power for 320 minutes (201 minutes leaving out major storm days), about 2.5 interruptions a year.

South Central Power Company residential price, 2024: 14.87 cents per kWh, about $160 a month for the average home across 117,469 residential customers (EIA-861).

South Central Power Company solar and meters, 2024: no net-metered solar reported under its own name (Buckeye Power, the co-ops' generation cooperative, files one Ohio net-metering row: 3,058 systems, 32.6 MW in 2024); 100% of its 127,851 meters are two-way smart (AMI) meters (EIA-861).

AEP Ohio outages, 2024: the average customer lost power for 272 minutes (158 minutes leaving out major storm days), about 1.1 interruptions a year.

AEP Ohio standard service offer price, 2024: 19.33 cents per kWh, about $174 a month for the average home, for the 550,768 residential customers who have not chosen a supplier; the other 788,464 pay AEP Ohio 10.75 cents per kWh for delivery plus their supplier's price (EIA-861).

AEP Ohio solar and meters, 2024: 11,606 customers run net-metered solar (158.9 MW, 11,036 of them homes); 79% of its 1,541,883 meters are two-way smart (AMI) meters, 21% drive-by automated reads (EIA-861).

Energy burden: households here spend an average 3.0% of income on electricity, gas and other fuels (about $2,446 a year against $80,694 of income); the 46% of households below 80% of the area median income spend 6.5%, and 22% of households fall in groups averaging 6% or more, the usual line for a high burden (DOE LEAD Tool, 2022 update, built from 2018 to 2022 survey data).

Rail crossings

Train accidents: 4 rail equipment accidents inside this ZIP since 2010 (2 derailments); $108,197 in damage. Latest: 2023, other (describe in narrative) (Norfolk Southern Railway Company); the most common cause here is switch improperly lined.

Franklin County has logged 68 rail accidents since 2010, 40 of them derailments, 3 hazmat cars releasing, 200 people evacuated (FRA Form 54). Yard mishaps at walking speed dominate; main-line derailments are the rare, dangerous ones.

Train counts and speeds are the railroad's last inventory update. Crossings with only crossbucks rely on the driver; Ohio has averaged about 77 crossing collisions a year from 2010 to 2025 (FRA Form 57), between 64 and 87 in a year.

Owners

state 11, county 7

Rated poor

Bulen-Pierce Road over Rathmel Ditch (1900, 429 a day)

Ratings come from the inspection every bridge gets at least every two years; poor means deterioration that needs repair, not imminent danger. FHWA's file is a yearly snapshot with inspections through early 2025, so a bridge replaced, re-rated or closed since then still shows its old rating here; ODOT's TIMS bridge inventory carries the current one. Traffic figures are the average daily counts the bridge owners filed with the inventory; most Ohio counts date from 2015 and some are older. County engineers own most of Ohio's small bridges and ODOT the big ones.

Traffic

Trucks

Busiest local road

county road 385, 8,895 vehicles a day

Annual average daily traffic is both directions combined, averaged over the year. County, township and city roads are labelled by their route number, which ODOT uses instead of the street name. Most city streets have no count, so the busiest local road is the busiest counted one. Interchange ramps are left out of the busiest-road pick; a ZIP with nothing but ramps shows one labelled ramp and its ODOT number.

Road deaths: 8 people died in 8 crashes inside this ZIP in 2020 to 2024 (1 pedestrian); 2 involved a drinking driver and 4 happened in the dark; most on US-23 (5). Too few people live here for a per-resident rate to mean much; deaths are counted where the crash happened, and many who die on through roads live elsewhere. (NHTSA FARS)

Drought (U.S. Drought Monitor): since 2020 Franklin County has spent 32 weeks in moderate drought or worse, 11 of them severe or worse (most recently 11 weeks in 2024), and 65 weeks at least abnormally dry. The worst since 2000 was extreme drought in 2024/09; 5% of all weeks since 2000 were in drought. As of 2026-09-01: no drought.

Long run (NOAA, Franklin County): the average year ran 53.2 °F over 1996 to 2025 against 51.5 °F over 1901 to 1930, 1.7 °F warmer (1.8 °F warmer than 1951 to 1980); the warmest year on record was 2024 at 56.4 °F, and 2025 came in at 53.1 °F. Precipitation averaged 41.7 inches a year lately against 39.7 a century ago, 5% more; the wettest year was 2018 with 55.1 inches, and 2025 brought 39.4. More rain in bigger bursts is what strains storm sewers and septic fields.

Stations: Columbus-Valley Crossing (7.2 mi, temperature and precipitation); John Glenn International Airport (13.5 mi, snowfall; 30 years of snowfall record). Normals are thirty-year averages, so a single winter can run far above or below them.

Air standards

Franklin County is a maintenance area for ozone (2008) (Columbus, OH, redesignated 2016), ozone (2015) (Columbus, OH, redesignated 2019), fine particulate (1997) (Columbus, OH, redesignated 2013), meaning it once failed that standard and must keep a plan to stay clean (EPA Green Book)

Ohio has 38 PM2.5 monitors, mostly in cities and near industry, so a rural ZIP borrows a reading from far away. 2025 includes Canadian wildfire smoke days. Air-toxics risk is EPA's modelled lifetime estimate for the county as a whole; EPA's national average is about 30 in a million, and formaldehyde, with the globally mixed carbon tetrachloride background and acetaldehyde, makes up most of it.

nothing was released on site in 2020

Pounds are what facilities report, not what reaches anyone: a ton of ammonia to the air and an ounce of mercury to a river are not the same risk. Off-site transfers go mostly to landfills and treatment plants elsewhere.

Dams

Nearest high-hazard dam: Hunters Run Structure R-42, 13.5 mi, condition poor (flood risk reduction, 24 ft high, 17 acre-feet, built 1959, on Hocking River - Offstream, local government owned).

Inside this ZIP: 1 dam, 0 high-hazard, 0 rated poor: Parsons Avenue Sludge Lagoons (significant hazard, condition satisfactory).

"High hazard" describes what a failure would do downstream, not the dam's shape; Ohio rates more than a third of its inventoried dams in poor condition, mostly small private lake dams. Emergency action plans are required for high-hazard dams.

Spills and releases

What spilled

diesel and fuel oil (12), oils and hydraulic fluid (6), unidentified material or sheen (5)

Largest

about 150 gallons of fuel diesel / diesel fuel (vehicle on or off road) in 2024, Columbus

Reached water

2 of them reached a creek, river, ditch or storm drain (named or unnamed)

By year

2021: 2, 2022: 8, 2023: 9, 2024: 6, 2025: 3, 2026: 4

Anyone who spills more than a reportable quantity must call Ohio EPA within 30 minutes, so the log mixes a few gallons of diesel on a highway shoulder with real releases; the reported volume is the caller's first estimate. Every report in Ohio EPA's open-data layer carries coordinates; air-pollution complaints and calls where nothing was found are left out of this count.

Oil and gas wells

Status

0 producing, 5 plugged or abandoned, the rest drilled but idle, gas storage, orphan, expired permits or unknown

Ohio has drilled since 1860, so most wells here are old, shallow and plugged; unplugged orphans and injection wells are the ones that matter for groundwater. Well-head points can be a few hundred feet off for the oldest records.

Abandoned mines

Undermined land can subside and old workings can discharge acid mine water; ODNR's Abandoned Mine Land program funds repairs, and mine-subsidence insurance is included automatically in 26 eastern counties and offered as an option in 11 more. Maps drawn before 1977 are incomplete, so "none" means none mapped.

Quarries, pits and working mines: 3 working operations inside this ZIP in 2015 (Columbus Plant #3, limestone, sand & gravel; Shelly Materials, Inc. - Lockbourne #1344, sand & gravel; South Columbus, sand & gravel); nearest South Columbus (sand & gravel, National Lime & Stone Co., 286,000 tons sold), 1.2 mi away in Franklin County; 2 within 3 miles, 6 within 10 (ODNR Industrial Minerals Locations, 2015, which includes surface and underground coal mines).

Septic

Very limited for a leach field under Ohio's rule

Basements

Elevation

692 feet above sea level at the ZIP's population center; Ohio runs from 455 feet where the Ohio River leaves the state to 1,549 feet at Campbell Hill

One point stands for the ZIP; soils change field by field, and a site evaluation is what the health department goes by. "Very limited" means the standard design will not work, not that nothing will.

Assessed wetland: 8 Ohio EPA study wetlands inside this ZIP; nearest N220-057, a wetland, 1.6 mi away: ORAM 27 of 100 (category 1) (surveyed 2012); 62 within 10 miles. Category 3 wetlands are the state's best and hardest to fill; category 1 are degraded.

Mapped from aerial photography, mostly 2004 to 2007 (the Lake Erie watersheds were re-mapped from 2021 imagery, a few areas date from 1976 to 2005 or 2014 to 2023), so small and seasonal wetlands are undercounted and ponds dug or filled since then are missing; a site delineation decides whether a lot is jurisdictional. Emergent means marsh, forested and shrub means swamp.

Land cover

Developed

19%: 5% high intensity (downtown blocks, big-box lots), 4% medium (apartments, small-lot houses), 5% low (houses on larger lots), 4.7% open space (lawns, parks, golf courses, road verges)

Farmland

61%: 53% row crops, 8.0% pasture and hay

Crops 2025

of 8,260 cropped acres, 60% soybeans, 30% corn, 2% wheat and small grains (plus 6% wheat followed by soybeans, counted under soybeans), 1% hay and alfalfa, 7% vegetables, orchards, fallow and other crops; 2,262 acres of pasture and grass (USDA Cropland Data Layer)

Forest

9.4%, plus 0.9% grass and shrub

Water and wetland

5.8% open water, 1.1% wetland, 3.3% barren (quarries, strip mines, beaches)

Paved and roofed

9% of the ZIP's surface is impervious; rain that lands there runs straight to a storm drain or stream instead of soaking in

Tree canopy

9% of the ZIP sits under tree canopy

Area

31.6 square miles of land

Land cover is classified from Landsat imagery at 30 metre pixels, so a house on a wooded lot can read as forest and a farm lane as open space. Stream health starts to slip once about 10% of a watershed is impervious, and is usually poor above 25%.

Unemployment-insurance records tie each job to a workplace and a home address; large employers sometimes report every worker at a headquarters, which inflates a few ZIPs. Self-employment, the military, the Postal Service, most farm work and a large part of federal civilian employment are missing (federal jobs come from OPM records that omit several agencies and, in practice, most of Wright-Patterson).

Before the settlers

The 1880 county history devotes a section to 'Ancient Remains,' recording that Hamilton Township 'contains a number of mounds, or earthworks, the only records of the existence of a former race.' It describes an ancient fort or ditch on the west bank of the Gahanna (Big Walnut) Creek in section 34, 'almost completely obliterated' by 1880; two mounds a quarter mile apart on Thomas M. Clark's farm, one round and larger, one oblong and smaller, in which 'implements and human bones were found' when opened; and several more mounds elsewhere in the township whose builders were already a mystery to nineteenth-century residents. The source does not name a culture, but the mound-and-earthwork pattern matches the Adena and Hopewell mound-building traditions documented elsewhere in central Ohio. No named historic-era Native village, trail, or camp is recorded specifically within the township's bounds. The 1880 history states directly that 'Hamilton township is within the, so-called, Congress lands' — placing it just west of the Refugee Tract, the 103,527-acre strip granted to Canadian and Nova Scotian supporters of the American Revolution that ran along the south line of the U.S. Military District through Franklin, Fairfield, Licking and Perry counties. The land was opened to settlement by the Treaty of Greenville, signed August 3, 1795, in which the Wyandot, Lenape (Delaware), Shawnee, Ottawa, Ojibwe (Chippewa), Potawatomi, Miami and other nations ceded most of what is now Ohio to the United States; Lucas Sullivant founded Franklinton, the county's first permanent settlement, a few miles to the northwest in 1797.

Franklin County

Franklin County's prehistoric record begins with the Adena, who built conical burial mounds through the Scioto and Olentangy valleys from roughly 800 BC to AD 100. An 1880 county history, citing archaeologist William C. Mills, put the historical count at 132 mounds and 28 earthen enclosures across the county, most since plowed away, dug into or built over. What can still be traced includes Shrum Mound (Campbell Mound) on McKinley Avenue, one of the last intact Adena mounds inside Columbus; Tom Cannon Mound at the confluence of Big and Little Darby creeks; the Toephner Mound, salvage-excavated… more

How Hamilton Township, Franklin County began

Hamilton Township, in southern Franklin County along the Scioto and Big Walnut (Gahanna) creeks, was organized under its present name in 1807, a few years after the first settlers arrived around 1800. It lies within the Congress Lands survey, just west of the Refugee Tract. Its main village, Groveport, formed in 1846 when two rival canal towns, Wert's Grove and Rarey's Port, merged and incorporated the next year; the township also holds Lockbourne and Obetz. Today much of its northern and western area has been absorbed into Columbus, and it is home to Rickenbacker Air National Guard Base and the Scioto Downs racetrack.

The name. No source found states why the township was given the name Hamilton. The 1880 county history says only that 'the township was organized under its present name in 1807,' when it still included the territory that later became Madison Township; it does not explain the choice of name. source

Stories

Two Rival Towns on the Canal

When the Ohio and Erie Canal reached southern Franklin County in the 1830s, two small settlements grew up side by side on it: Wert's Grove and Rarey's Port, named for local landowning families. Rather than compete indefinitely, the two merged into a single town in 1846, and the combined village was incorporated the next year, 1847, when a post office named Groveport also opened. The Rarey and Wert families are still visible in the village today — Commons hosts modern photographs of both the Rarey House and the Jacob Wert House standing in Groveport. The canal that brought the two towns together is remembered with a historical marker in the village. source

Mounds the Settlers Could Not Explain

When Hamilton Township's farms were cleared in the early 1800s, settlers found evidence that someone had lived on this land long before them. The 1880 county history records an old fort or ditch on the west bank of the Gahanna Creek in section 34, already 'almost completely obliterated,' and two burial mounds a quarter mile apart on Thomas M. Clark's farm — one round and larger, one oblong and smaller. When local residents opened the mounds they found human bones and implements inside, but no one in 1880 could say who had built them or when. Several smaller mounds elsewhere in the township are mentioned only in passing, suggesting the full extent of the township's ancient earthworks was never systematically recorded. source

Mills on the Gahanna

Water power drove the township's earliest industry. Michael Fisher, one of the first settlers, built a sawmill on the Scioto in the northwest part of the township not long after he arrived from Virginia around 1800. Others followed on the Gahanna (Big Walnut) Creek: Joseph Murray and Isaac Weatherington ran a sawmill there, and John Herr and Francis Johnston combined a sawmill, gristmill, and distillery on the same stream. Decades later, in 1834, brothers John and Cornelius McCarthy built a sawmill at Shadeville, and the Cottage Mills were raised at the same crossroads in 1841 — evidence that the township's little mill villages kept growing well after the first pioneer generation had died out. source

A Log House Moved to Save It

One of the township's oldest surviving buildings is a log house built in Groveport in 1815, back when the village was still two separate hamlets on the canal-to-be. As Groveport grew up around it across the nineteenth and twentieth centuries, the little building survived long enough to be recognized as historic, and in 1974 it was physically relocated to a new site near Groveport Cemetery to preserve it. It was later listed on the National Register of Historic Places as one of the Groveport Log Houses, alongside the Groveport Town Hall Historic Group and Groveport United Methodist Church, giving the merged canal town three separate National Register listings from its nineteenth-century core. source

Not found: No source found explains why the township was named Hamilton. The 1880 chapter and the township's Wikipedia article are silent on Canal Winchester and on any railroad through the township, so neither is asserted here. The culture responsible for the township's mounds (Adena, Hopewell, or other) is not identified by the source consulted, only inferred from the regional pattern. No pre-1930 postcard or photograph of the township or Groveport was located in this search pass on Wikimedia Commons; all photos used are 21st-century images of historic structures, dated as such.

Franklin County

Franklin County was created by the Ohio General Assembly on April 30, 1803, out of Ross County, and named for Benjamin Franklin. Its first town, Franklinton, was platted in 1797 by surveyor Lucas Sullivant at the forks of the Scioto and Olentangy rivers, ground the Wyandot held as their principal territory in the northern Scioto valley and that Mingo, Shawnee and Lenape (Delaware) people also lived on, hunted and traveled through, in the years after the Treaty of Greenville (1795) opened the country to American survey. The county seat moved from Franklinton to the newly platted state capital, Columbus, in 1824, and the county grew up around a feeder canal, the National Road, the railroads, Camp Chase, Ohio State University and, after 1953, a water-and-sewer annexation policy that pulled dozens of townships and suburbs into the city. Floods bookend much of its written history, from the 1798 flood that drove Franklinton's founders to higher ground to the March 1913 flood that killed about 93 people in that same low neighborhood. Today Franklin County, anchored by Columbus, is Ohio's most populous county.

Settled 1797 (Franklinton, the county's first settlement, platted by Lucas Sullivant), incorporated 1803-04-30; by Ohio General Assembly, organized out of Ross County. source

The name. Franklin County was named for Benjamin Franklin, following a pattern common among early Ohio counties of honoring Revolutionary-era statesmen. Lucas Sullivant, an admirer of Franklin, had already named the county's first town, Franklinton, for him in 1797, six years before the county itself was organized and took the same name.

The county seat. Franklinton was the county seat from 1803 until 1824. The legislature had meanwhile chosen an undeveloped site on the 'High Banks' opposite Franklinton, over competing offers from Franklinton, Dublin, Worthington and Delaware, as the new state capital on February 14, 1812; the resulting town of Columbus was incorporated as a borough on February 10, 1816, the year state government moved in, chartered as a city on March 3, 1834, and formally took over as county seat in 1824.

County stories

The Mound on Mound Street

When surveyor Joel Wright laid out Columbus in 1812, High Street ran north from Franklinton until it hit an ancient burial mound, and the street simply bent around it. Traffic grew heavy enough by the 1830s that the city leveled the mound, and workers found human bones and a carved stone owl pipe that passed into antiquarian Joseph Sullivant's collection. The mound's clay went into brick, some fired for the first county courthouse in Franklinton and more for Ohio's original 1816 state house, a building that itself burned down in 1852. Columbus writer Thomas Backus, publishing as 'Fabius,' marked the mound's demolition with a newspaper poem pleading, 'Spare! oh spare, the buried brave.' Only the street name survives at the corner of Mound and High today. source

Tarhe's Peace at Franklinton

By the spring of 1813 the War of 1812 had central Ohio's settlers in what one county history called 'feverish anxiety,' fearing the Native nations still to the north and west would join the British side. On June 21, 1813, General William Henry Harrison called a council on Lucas Sullivant's own grounds at Franklinton, and about fifty Wyandot, Shawnee, Lenape (Delaware) and Seneca representatives came to hear him. The Wyandot sachem Tarhe, known as the Crane, rose after Harrison's speech and took the general's hand, and the other delegations followed; settlers, by one account written decades later, answered with 'jubilant shouts' and tears of relief. The agreement did not commit the tribes to fight for the United States, only to stay neutral and keep their families within the settlements, but it lifted Franklinton's standing fear of attack for the rest of the war. Tarhe, already elderly and a signer of the Treaty of Greenville eighteen years before, would be dead within two years; Harrison would be President within thirty. source

The Execution of Leatherlips

Leatherlips, a Wyandot chief whose name in his own language was rendered Shateyaronyah, signed the Treaty of Greenville in 1795 and spent the years after urging cooperation with American settlers, even selling land to William Henry Harrison. That accommodation put him at odds with the resistance movement building around the Shawnee leader Tecumseh and his brother Tenskwatawa, and in spring 1810 a Wyandot council convicted him of witchcraft, a charge later historians generally read as cover for a political execution. Six Wyandot found him encamped on the Scioto about twelve miles above Franklinton, near present-day Dublin; nearby settlers, the Sells brothers, offered a horse and roughly $300 in gold for his life, but the delegation refused. On June 1, 1810, Leatherlips dressed in his finest clothes, painted his face, ate a last meal and walked to a grave already dug for him, singing his death song in Wyandot, and was killed with a tomahawk after two rounds of prayer. The Wyandot Club of Columbus raised a stone marker over the grave in 1889, and in 1990 the Dublin Arts Council dedicated a twelve-foot limestone portrait bust by sculptor Ralph Helmick on the bluff above the river, in Dublin's Scioto Park. source

A River Twice Misnamed

The stream that runs past Worthington and through Columbus to the Scioto carried a Lenape (Delaware) name, recorded by early travelers as keenhongsheconsepung, meaning roughly 'sharp tool river,' for the shale settlers found along its banks and used as whetstones; English speakers simply translated it as the Whetstone River. In 1833 the Ohio General Assembly, trying to restore Native names to the state's waterways, renamed it Olentangy, a Delaware word for 'river of the red face paint' -- except that name properly belonged to a different stream, Big Darby Creek, and the legislature's mix-up simply stuck. The Scioto, which the Whetstone/Olentangy joins at the site of old Franklinton, keeps its own Native name intact: a Wyandot word for deer, fitting for a valley early travelers described as thick with game. Parts of Marion County, at the river's north end, still call it the Whetstone today, a reminder the 1833 renaming never fully took. source

Camp Chase: Training Ground and Prison

Ohio mustered its Civil War volunteers beginning in May 1861 at a camp on the Hilltop west of Franklinton, named Camp Chase for former governor and Treasury secretary Salmon P. Chase. Over the war's four years as many as 150,000 Union soldiers passed through on their way to the front, but the camp is remembered chiefly for what it became: a prison stockade that by February 1865 held more than 9,400 Confederate soldiers, sailors and political prisoners on a site barely a square mile in size. Conditions were hard rather than deliberately cruel, but overcrowding brought a smallpox outbreak in the winter of 1863-64 that killed hundreds, and disease filled the camp's cemetery faster than combat ever did. More than 2,200 Confederate dead from Camp Chase and the nearby Camp Dennison hospital are buried in the Camp Chase Confederate Cemetery on Sullivant Avenue, the only piece of the camp the army did not dismantle after closing it in 1865. source

Water for Annexation

For four decades after 1910, Columbus barely grew, adding fewer than twenty square miles while its postwar population boomed and its water system strained to keep pace. Maynard 'Jack' Sensenbrenner, elected mayor in an upset in 1953, turned the shortage into policy: in early 1954 the city barred new water and sewer connections outside its limits, so any suburb or township wanting city water first had to agree to annexation. He said as much publicly, telling residents in October 1953 he was 'bitterly opposed to selling water to any outside community until Columbus' own needs are met.' The city added nearly fifty square miles in the 1950s alone, against half a square mile in the 1940s, and grew from roughly forty square miles to more than two hundred by 1980, a policy credited with keeping Columbus from being boxed in by suburbs the way Cleveland and Cincinnati were. It also explains why Franklin County today holds dozens of small municipalities and townships whose boundaries trace back to whether and when each needed Columbus's water. source
