ZIP code 43064: Jerome Township and Plain City

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

42.2 µg/L yearly mean in 2019, the last year in the file (limit 80); worst yearly mean 60.5, highest single sample 85.4; 129 samples from 2012 to 2019

HAA5

12.6 µg/L yearly mean in the last year sampled (limit 60); worst yearly mean 16.2, highest sample 28.1; 128 samples

Nitrate

highest of 96 samples was 1.52 mg/L as nitrogen (2017; limit 10); 0.62 in 2019, the last year sampled. Nitrate above 10 is unsafe for infants

Arsenic

not detected in 8 samples (limit 10)

Solvents and fuels

benzene, carbon tetrachloride, 1,2-dichloroethane, trichloroethylene, tetrachloroethylene, vinyl chloride not detected in 8 samples

Bacteria

7 of 2,409 routine tap samples (0.29%) tested positive for total coliform in 2012 to 2019, 0 of 302 in 2019; E. coli never found in the 7 tap samples tested for it. Coliform itself is a warning sign; E. coli means sewage or manure reached the water

Farm chemicals

atrazine, alachlor not detected in 10 samples

Metals

chromium, cadmium, barium, mercury, selenium, thallium not detected in 8 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

12 samples in 2023 to 2026 at the entry point to the distribution system: none of the 29 PFAS detected

Ohio EPA 2020

1 plant tested (latest 2020-07): nothing detected for the six PFAS tested

Ohio EPA latest

1 plant sampled by Ohio EPA, most recently 2020-07 (Ohio EPA statewide sampling status map)

Firefighting foam: 2 fire departments or other holders in Union County registered 160 gallons of PFAS-based AFFF foam with Ohio EPA, 160 gallons in opened containers; the state is collecting it for disposal so it is never sprayed again.

Lithium: found in 1 of 4 UCMR 5 samples at Marysville City, highest 13.4 µg/L, last sampled 2026. 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

0.8 ppb in the sampling period ending 2025-12

Record

6 sampling periods since 2016, none above 10 ppb

Service lines

11,570 inventoried: 23 lead, 8 galvanized needing replacement, 738 unknown, 10,801 not lead (reported all required service line types)

Children: this ZIP is not on the Ohio Department of Health's high-risk list for childhood lead testing; children on Medicaid or in pre-1978 housing with peeling paint should still be tested.

Housing age: 15% of the homes here were built before 1960 and 10% before 1940, when lead service lines, lead solder and lead paint were common; 26% 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: aeration, corrosion control, coagulation and settling, chlorine disinfection, dechlorination, lime softening, ozone, powdered activated carbon, sand or media filtration.

Measured fluoride: 1.02 mg/L on average at the plant's entry points in 2019 (in the range dentists aim for); samples ran from 0.85 to 1.31 mg/L across 8 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 100% of Union 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

12 detections at the intake across 1 bloom season (2017); none since 2024

Treated water

never detected after treatment

Monitoring

326 samples from 2016 to 2026, latest 2026-08-25

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.

Bedrock

Undifferentiated Salina Dolomite, Includes Bass Islands Group, yielding > 100 gpm to a well

Setting

Sand and Gravel; water table 15-30 ft down, 4-7 in/yr recharge, clay loam soil (hydrogeologic setting 7Ja); pesticide index 147

Well logs

2,559 drilled wells on file (147.9 per 1,000 residents), median 100 ft deep, 20 gallons a minute median test yield, water 27 ft down

Aquifers

85% of wells in bedrock, 15% in sand, gravel and other unconsolidated material; typical well drilled 1995, 1,041 since 2000; uses: Domestic 2,167, Agric/Irrig 91

Wellhead protection

2% of this ZIP lies inside Ohio EPA source water protection areas for 19 public water systems (Suburbans Community Mhp, Canaan Community Mhp, Mid-Ohio Wsd - Jackson Street Wtp), 1% inside inner management zones, the ground a well draws from within a year; the largest, Suburbans Community Mhp, is rated moderate susceptibility in a carbonate bedrock setting

Geology

6% of the ZIP is a sensitive geologic setting, where thin or sandy cover leaves the aquifer open to what soaks in from the surface; its population center sits on Silurian-Devonian limestone and dolomite known to form karst, under more than 20 ft of drift; nearest verified sinkhole 6.4 mi away (Ohio EPA and ODNR Geological Survey)

Injection wells

46 Class V injection wells on Ohio EPA's books inside this ZIP (42 active): 1 stormwater drainage, 15 large septic, 23 cleanup injection, 3 vehicle waste, 4 other; these put fluids underground above or into drinking water aquifers

Water table

FR-10 OH monitoring well (ODNR), 13.3 mi away: water 43.5 ft below ground on 2026-08-25; averaged 42.5 ft in 2015 to 2019 and 44.3 ft over the latest year, so the table is running about 1.8 ft lower; range 40.5 to 45.4 ft over 4,163 readings since 2015

Nitrate risk

EPA researchers put the chance that a public water system in the Robinson Run-Big Darby Creek subwatershed exceeds the nitrate limit at 26% if it draws on groundwater and 44% 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 Plain City Wellfield (Madison County), 1.3 mi away: 377 ft deep in limestone or dolomite (UST and Greenfield aquifer); bedrock 100 ft down; wells there yield 5 to 25 gallons a minute; on standby. 3 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.

Aquifer exposure

Karst

the population center sits on Silurian-Devonian limestone and dolomite known to form karst, under more than 20 ft of drift; no mapped sinkhole inside the ZIP; nearest verified sinkhole 6.4 mi from the center

Wellhead protection

2% of the ZIP lies inside Ohio EPA source water protection areas for 19 public water systems (Suburbans Community Mhp, Canaan Community Mhp, Mid-Ohio Wsd - Jackson Street Wtp), 1% inside inner management zones, the ground a well draws from within a year; the largest, Suburbans Community Mhp, is rated moderate susceptibility in a carbonate bedrock setting

Vulnerability index

DRASTIC 129 (ODNR; higher means a spill at the surface reaches the aquifer more easily)

Sensitive settings are outwash plains, buried valleys, karst and shallow bedrock, mapped statewide by Ohio EPA for siting decisions. Exposure is not contamination: it says how quickly a spill, a failing tank or heavy manure would reach the water table, not whether one has.

Sewage treatment

Size

1.25 million gallons a day design flow

Compliance

9 of the last 12 quarters with a violation; currently in significant noncompliance (Compliance/Permit Schedule - Violations); 158 effluent limit exceedances in 3 years

Other discharge permits: 6 facilities inside this ZIP other than sewage plants hold a Clean Water Act permit (factories, water plants, quarries, package plants, storm water); 43 facility-quarters with a violation in the last three years; $2,500 in Clean Water Act penalties in the last five years.

Sewage sludge: 7 farm fields covering 318 acres inside this ZIP are permitted for spreading treated biosolids, mostly from Plain City Wwtp (174 acres), Oxford Wwtp (129 acres), Springfield Waste Water Treatment (15 acres) (Ohio EPA). Biosolids carry nutrients and, increasingly under scrutiny, PFAS.

Sludge source: 1 permitted biosolids generator is inside this ZIP; nearest Plain City WWTP, 1.3 mi away; 2 within 10 miles (Ohio EPA).

State water loans: 7 projects inside this ZIP have borrowed $19.8 million from Ohio EPA's revolving loan funds since 2019 (4 sewer, storm water and runoff projects for $14.5 million; 2 drinking water projects for $4.2 million). Largest: WWTP Improvements (Mid-Ohio Water and Sewer District, 2023, $12.9 million); latest: SR 161 Waterline Extension (Mid-Ohio Water and Sewer District, 2026, $3.4 million). Below-market loans are how most Ohio treatment plants and water mains get rebuilt.

Sewer planning: 87% of it is assigned to Multiple as the designated sewage management agency under Ohio's Clean Water Act section 208 plan (darby prescriptions); 9 agencies share the ZIP. The 208 plan decides who may build and extend sewers.

Stormwater: this ZIP lies outside Ohio EPA's regulated MS4 areas, so its storm drains and ditches carry runoff without a municipal stormwater permit. 1 site with an address in this ZIP holds its own industrial stormwater permit (Fedex Ground - West Columbus) (EPA Facility Finder).

Plants inside this ZIP: Plain City Wwtp (1.25 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.

Fish advisories (Ohio EPA): Big Darby Creek (U.S. Route 42 (Plain City) to Alkire Road (Georgesville)): channel catfish one meal a month, smallmouth bass one meal a month (PCBs, mercury). Statewide, every other fish is one meal a week because of mercury.

Nearest stream assessment (Ohio EPA): Big Darby Creek At Plain City, Upst. U.S. Rt. 42 And Ranco on the Big Darby Creek, 1.2 mi away, draining 138 square miles: full attainment of its exceptional warmwater use; fish IBI 54 of 60 (2014); bug ICI 52 of 60 (2014); habitat QHEI 78.3 of 100. 15 assessed sites inside the ZIP, 8 within 3 miles, 57 within 10. Scores above about 40 (IBI), 36 (ICI) and 60 (QHEI) mean a healthy warmwater stream.

Stream designations (Ohio EPA water quality standards): 50 miles of designated streams cross this ZIP: 30.6 mi warmwater habitat, 17.7 mi exceptional warmwater habitat, 1.8 mi modified warmwater habitat. Nearest specially protected stream: the Big Darby creek, 0.8 mi away, an Outstanding State Water; 24% 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: the nearest reach Ohio EPA proposes to add to the antidegradation tiers is the Scioto River (Mill creek above O'Shaughnessy reservoir (RM 155.4) to the mouth), 6.9 mi away, as Outstanding State Water for recreation.

Critical habitat: federally designated critical habitat for the rayed bean (endangered, 2026), the rabbitsfoot (threatened, 2015), the snuffbox mussel (endangered, 2026) crosses this ZIP, so federal permits for work in those waters must avoid harming them (U.S. Fish and Wildlife Service).

PFAS in the river (Ohio EPA large river survey): at Scioto R. N Of Dublin @ I-270, 7.4 mi away, the water carried 77.21 ng/L of total PFAS (PFOA 3.8, PFOS 2 ng/L); fish fillets held 37.2 ng/g in bluegill and 19.12 ng/g in catfish (PFOS 14 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 Union County used about 230 metric tons of pesticide active ingredient, 525 kg per square mile, 12th of Ohio's 88 counties. Largest: glyphosate 90 t, atrazine 28 t, metolachlor 28 t, acetochlor 11 t, 2,4-D 9 t. Atrazine, the corn herbicide, is the pesticide that most often shows up in Ohio tap water after spring rains; this county used 28 t of it.

Farms (2022 Census of Agriculture): 1,020 farms work 216,646 acres of Union County, with 69.1% of its land in cropland, 212 acres to a farm. 10,494 cattle, 19,654 hogs, 2,317,440 laying hens, 796 broilers, 160 turkeys; 51,562 acres of corn and 113,461 of soybeans. Sales $309 million, 51% 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.

Road salt: 1 state chloride-reduction grant inside this ZIP; nearest went to Village of Plain City (facility, 2024-2025), 2.1 mi away; 1 in Union County. H2Ohio pays for brine makers, calibrated spreaders and covered salt barns so less chloride reaches streams and wells.

The population center sits in the Robinson Run-Big Darby Creek subwatershed; its water runs on through Worthington Ditch-Big Darby Creek, then Silver Ditch-Big Darby Creek, then Gay Run-Big Darby Creek.

In 2015 Union County drew about 9 million gallons a day of fresh water (USGS): 1.2 million for public supply (100% from wells, 27,100 people served at 27 gallons a person a day at home), 3.4 million for industry, 0.2 million for irrigation, 1.7 million for mining; 27,100 residents drew their own well water.

EnviroAtlas, Robinson Run-Big Darby Creek: 200 to 500 acres in the Conservation Reserve Program; 18,456 acres of grain crops; 63 miles of streams (1.4 per square mile); water use of 542 thousand gallons a day for homes and 7 thousand for farms; 38.4 inches of rain and snow a year; 9.6 kg of nitrogen per hectare falling from the air each year; farm nitrogen of 0 kg per hectare a year as manure and 48.3 kg as synthetic fertilizer; 36% of the farmland sits on drained hydric soils; potentially restorable wetlands on farmland cover 49% of the subwatershed; 2.8% of the land is paved or roofed; 31% of the stream banks keep natural cover (EPA EnviroAtlas national metrics, 2010s vintages).

Stream permits: 52% of this ZIP drains to streams Ohio EPA rates high quality, where a project that fills, pipes or crosses a stream needs an individual Ohio EPA 401 water quality review; 23% drains toward high-quality waters farther down and might qualify for the Army Corps' blanket nationwide permits after a field screening and 26% can use those nationwide permits outright (Ohio EPA 401 nationwide permit eligibility map).

Zillow's typical home value here is $547K (2026-07), up 1% over the year, up 22% over five years and up 73% over ten. Typical asking rent $2,155 a month (2026-07), down 3% over the year.

On the market (Realtor.com, August 2026): median asking price $649,900 (up 3.2% in a year), $243 per square foot for a typical 2,820 sq ft listing; 93 active listings, 36 new this month; listings spend a median 56 days on the market (up 11% from a year earlier); 28% of listings have cut their price.

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.

Municipal income tax

Plain City 1.5% (25% of residents); township residents outside a city or village pay none. Charged on wages and business profits where you work and, after credits, where you live.

School district income tax

Jonathan Alder Local 1.25% (61% of residents), Dublin City none (28% of residents), Fairbanks Local 1% (11% of residents). Voted by the district and collected with the state income tax.

Sales tax

7% combined rate in Union 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.

Scioto Darby CR.Rd over Big Darby (Scioto Darby) (1986, 11,541 a day); USR 42 over Robinson Run (1982, 8,156 a day) and 3 more

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

Freeway volumes

7 segments carry 50,000 or more a day

Busiest local road

county road 24, 27,174 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: 15 people died in 13 crashes inside this ZIP in 2020 to 2024 (7 motorcyclists); 3 involved a drinking driver and 2 happened in the dark; most on US-42 LONDON DELAWARE RD (5). That is 17.3 deaths a year per 100,000 residents against 10.6 across Ohio's ZIPs; deaths are counted where the crash happened, and many who die live elsewhere. (NHTSA FARS)

Degree days

5,546 heating, 968 cooling (base 65°F): the higher the heating number, the bigger the winter gas bill

Drought (U.S. Drought Monitor): since 2020 Union County has spent 32 weeks in moderate drought or worse, 6 of them severe or worse (most recently 1 week in 2025), and 95 weeks at least abnormally dry. The worst since 2000 was severe drought in 2025/10; 5% of all weeks since 2000 were in drought. As of 2026-09-01: no drought.

Long run (NOAA, Union County): the average year ran 51.9 °F over 1996 to 2025 against 50.1 °F over 1901 to 1930, 1.8 °F warmer (1.6 °F warmer than 1951 to 1980); the warmest year on record was 2024 at 54.8 °F, and 2025 came in at 51.7 °F. Precipitation averaged 39.5 inches a year lately against 37.0 a century ago, 7% more; the wettest year was 2011 with 54.2 inches, and 2025 brought 33.4. More rain in bigger bursts is what strains storm sewers and septic fields.

Stations: Marysville (5.1 mi, temperature and precipitation and snowfall; 14 years of snowfall record). Normals are thirty-year averages, so a single winter can run far above or below them; NOAA marks this snowfall normal provisional because the station record is too short or too patchy for a standard normal, and the temperature and precipitation figures here skip stations with under 10 years.

No inventoried dam sits inside this ZIP.

"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

sewage, manure or storm water (7), diesel and fuel oil (4), other chemicals (2)

Largest

about 300 gallons of fuel diesel / diesel fuel (vehicle on or off road) in 2023, Canaan Twp

Reached water

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

By year

2021: 3, 2022: 1, 2023: 2, 2024: 3, 2025: 8, 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, 8 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.

Soils and septic

Soil

Crosby silt loam, Southern Ohio Till Plain, 0 to 2 percent slopes; Crosby makes up 90% of the unit, 1% slope

Water

Septic

Very limited for a leach field under Ohio's rule

Basements

Elevation

932 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.

Wetlands

278 acres pond, 166 acres emergent wetland, 146 acres forested/shrub wetland. Largest single wetland: 18 acres of freshwater pond.

Vernal pools: 36 potential high-quality vernal pools covering 15.5 acres lie inside this ZIP (Ohio EPA screening): seasonal woodland pools that dry by summer, hold no fish, and are where salamanders and fairy shrimp breed.

High-quality wetlands: nearest is Griggs Reservoir Park (City of Columbus Parks and Recreation), 9 acres, 7.7 mi away; 3 within 10 miles.

Mitigation sites: 1 stream or wetland mitigation site inside this ZIP; nearest ODOT Darby Watershed - Yutzy Property, 3.5 mi away (a pooled mitigation site); 6 within 10 miles. These are wetlands and streams built or restored to replace ones filled under Clean Water Act permits.

Assessed wetland: 8 Ohio EPA study wetlands inside this ZIP; nearest N220-070, a wetland, 3.2 mi away: ORAM 34 of 100 (category 2) (surveyed 2012); 29 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.

Farmland

81%: 76% row crops, 5.5% pasture and hay

Crops 2025

of 45,365 cropped acres, 55% soybeans, 35% corn, 4% wheat and small grains (plus 2% wheat followed by soybeans, counted under soybeans), 3% hay and alfalfa, 3% vegetables, orchards, fallow and other crops; 6,745 acres of pasture and grass (USDA Cropland Data Layer)

Forest

6.9%, plus 0.5% grass and shrub

Water and wetland

0.4% open water, 0.3% wetland

Paved and roofed

3% 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

6% of the ZIP sits under tree canopy

Area

103.9 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%.

Trend

violent offenses up 47% from 38 in 2023; property down 11% from 181

Rates cover the whole agency's territory, not this ZIP alone: a city's downtown and its quiet edges share one number. Murders, rapes and assaults are counted once per victim and other offenses once per incident, as the FBI's Crime Data Explorer does; a large department's figures can still fall somewhat short of the Explorer's, which takes in later submissions, and a sheriff's population is only the unincorporated area it serves.

Source: FBI Crime Data Explorer, NIBRS incident data for Ohio, 2024 (2023 for the trend): Group A offenses per reporting agency (violent = murder, rape, robbery, aggravated assault; property = burglary, larceny, motor vehicle theft, arson), murders, rapes and assaults counted once per victim; the agency is the police department of the ZIP's largest local government (city, village or township) when it has one of its own, found in the FBI's 2023 and 2024 rosters or the USGS police station inventory, otherwise the sheriff of the ZIP's county; a rate needs at least six months of 2024 on file and is annualized from fewer than 12; the Ohio figures pool the 511 police departments and sheriff's offices with all 12 months on file · FBI Crime Data Explorer · USGS structures service

Police and post office

1 station within 3 miles, 4 within 8. Inside this ZIP: Plain City Police Department.

Nearest post office: Plain City Post Office, 1.4 mi; 1 inside this ZIP.

Townships without their own department are policed by the county sheriff, whose office may be at the county seat; the state highway patrol covers the roads. The inventory lists stations, not patrol zones. It also misses some departments and still lists some that have closed; the atlas adds the departments that reported at least six months of 2024 crimes to the FBI but had no station in it, and drops the closed and duplicate records it found.
