ZIP code 45426: Trotwood and Dayton

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

26.1 µg/L yearly mean in 2019, the last year in the file (limit 80); worst yearly mean 30.8, highest single sample 57.4; 128 samples from 2012 to 2019

HAA5

4.7 µg/L yearly mean in the last year sampled (limit 60); worst yearly mean 5.7, highest sample 19.9; 128 samples

Sampled at

the entry points of Dayton Public Water System, which treats the water Montgomery County Water Services 2 sells; the nitrate, arsenic, radioactivity, solvent, farm-chemical and metal rows below are its results

Plants

Dayton Public Water System runs 2 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 2, not only Ottawa Water Treatment Plant (Mad River Well Field), which serves this ZIP; a sample over a limit may be from another plant

Nitrate

highest of 260 samples was 1.9 mg/L as nitrogen (2019; limit 10); 1.9 in 2019, the last year sampled. Nitrate above 10 is unsafe for infants

Arsenic

not detected in 31 samples (limit 10)

Solvents and fuels

trichloroethylene (TCE) detected in 1 of 98 samples, highest 1.06 µg/L (limit 5); benzene, carbon tetrachloride, 1,2-dichloroethane, tetrachloroethylene, vinyl chloride not detected in 98 samples

Bacteria

6 of 7,783 routine tap samples (0.08%) tested positive for total coliform in 2012 to 2019, 1 of 972 in 2019; E. coli never found in the 7,808 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 18 samples

Metals

barium in 31 of 33 samples, highest 94.2 µg/L (limit 2,000); not detected: chromium in 31 samples, cadmium in 31 samples, mercury in 22 samples, selenium in 28 samples, thallium in 22 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.

5 samples in 2023 to 2024 at the entry point to the distribution system: PFHxS 9.4, PFOS 7.6, PFHxA 5.2 ng/L

Sources

The system reported a known PFAS source near its supply

Ohio EPA 2020 at Dayton Public Water System

2 plants tested (latest 2021-02): PFHxS 7.7 ppt, against Ohio's action level of 140 ppt

Ohio EPA latest at Dayton Public Water System

2 plants sampled by Ohio EPA, most recently 2026-04 (Ohio EPA statewide sampling status map)

Firefighting foam: 12 fire departments or other holders in Montgomery County registered 3,025 gallons of PFAS-based AFFF foam with Ohio EPA, 2,030 gallons in opened containers; the state is collecting it for disposal so it is never sprayed again.

Lithium: not detected in 4 UCMR 5 samples at Montgomery County Water Services 2 (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

0 ppb in the sampling period ending 2025-12

Highest since 2016

4.5 ppb (2017-12); never above 10 ppb in 9 periods

Service lines

30,792 inventoried: 653 lead, 98 galvanized needing replacement, 12,174 unknown, 17,867 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: 32% of the homes here were built before 1960 and 11% before 1940, when lead service lines, lead solder and lead paint were common; 82% 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 at Dayton Public Water System, which supplies Montgomery County Water Services 2: corrosion control, coagulation and settling, chlorine disinfection, lime softening, sand or media filtration.

Measured fluoride: 0.88 mg/L on average leaving the plants of Dayton Public Water System, which supplies Montgomery County Water Services 2, in 2019 (in the range dentists aim for); samples ran from 0.84 to 1 mg/L across 16 samples in 2012 to 2019 (EPA compliance monitoring, Dayton Public Water System). Natural fluoride in Ohio well water runs from a trace to over 2 mg/L in parts of the northwest.

The health department counts 98.9% of Montgomery 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. Water bought from another utility arrives already treated, so the steps shown are the supplier's. The treatment list is what each system registered with EPA and can lag a plant upgrade.

Algal toxins

Raw water

no microcystin detected at the intake

Treated water

never detected after treatment

Monitoring

363 samples from 2016 to 2026, latest 2026-05-19

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.

Groundwater

Under the surface

till over sand and gravel, part of the Arcanum Ground Moraine Aquifer (ground moraine setting); wells there yield 25 - 100 gallons a minute, deposits 25 - 100 ft thick

Bedrock

Ordovician undivided, yielding 0 - 5 gpm to a well

Sole source

inside the EPA-designated Greater Miami sole source aquifer, the area's only practical supply of drinking water

Setting

Sand and Gravel; water table 15-30 ft down, 4-7 in/yr recharge, clay loam soil (hydrogeologic setting 7Ja); pesticide index 143

Karst

6 karst and spring points in ODNR's inventory inside the ZIP (0 field-verified), 0.3 per square mile

Well logs

431 drilled wells on file (29.9 per 1,000 residents), median 56 ft deep, 8 gallons a minute median test yield, water 17 ft down

Aquifers

56% of wells in bedrock, 44% in sand, gravel and other unconsolidated material; typical well drilled 1980, 101 since 2000; uses: Domestic 305, Monitor 79

Geology

58% 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 Ordovician limestone and shale known to form karst, under more than 20 ft of drift; nearest verified sinkhole 10.7 mi away (Ohio EPA and ODNR Geological Survey)

Injection wells

14 Class V injection wells on Ohio EPA's books inside this ZIP (13 active): 13 cleanup injection, 1 vehicle waste; these put fluids underground above or into drinking water aquifers

Water table

MT-6 OH monitoring well (ODNR), 6.5 mi away: water 62 ft below ground on 2026-09-03; averaged 34.1 ft in 2015 to 2019 and 48.4 ft over the latest year, so the table is running about 14.3 ft lower; range 21.3 to 62 ft over 3,974 readings since 2015

Nitrate risk

EPA researchers put the chance that a public water system in the Dry Run-Wolf Creek subwatershed exceeds the nitrate limit at 28% if it draws on groundwater and 49% 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 Wolf Creek Spring (Montgomery County), 4.4 mi away: in sand and gravel; wells there yield 5 to 25 gallons a minute; not currently sampled. 14 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 Ordovician limestone and shale known to form karst, under more than 20 ft of drift; no mapped sinkhole inside the ZIP; nearest verified sinkhole 10.7 mi from the center

Wellhead protection

less than half a percent of this ZIP lies inside any public water system's five-year wellhead protection area

Vulnerability index

DRASTIC 124 (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

2.5 million gallons a day design flow; a major facility

Compliance

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

Sewage sludge: 30 farm fields covering 489 acres inside this ZIP are permitted for spreading treated biosolids, mostly from Miamisburg Water Reclamation Facility (275 acres), Montgomery Co Western Regional Wrf (138 acres), Middletown Wwtp (76 acres) (Ohio EPA). Biosolids carry nutrients and, increasingly under scrutiny, PFAS.

Sludge source: nearest Englewood WWTP, 4.1 mi away (a major plant); 8 within 10 miles (Ohio EPA).

State water loans: no Ohio EPA revolving-fund project inside this ZIP; the nearest is Sewer Extension to Brookville Lake Estates MHP (Montgomery County, 2017, $1.3 million), 5.9 mi away.

Stormwater: 61% of this ZIP lies inside Ohio EPA's regulated MS4 areas, mostly the City of Trotwood storm sewer system (3 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). 1 site with an address in this ZIP holds its own industrial stormwater permit (Lkq Pick Your Part) (EPA Facility Finder).

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.

Nearest stream assessment (Ohio EPA): N. Br. Wolf Creek At Trotwood @ Union Rd. on the North Branch Wolf Creek, 0.8 mi away, draining 23 square miles: full attainment of its warmwater use; fish IBI 46 of 60 (2010); bugs rated very good; habitat QHEI 72.5 of 100. 3 assessed sites inside the ZIP, 3 within 3 miles, 49 within 10. Scores above about 40 (IBI), 36 (ICI) and 60 (QHEI) mean a healthy warmwater stream.

Stream designations (Ohio EPA water quality standards): 15.4 miles of designated streams cross this ZIP: 15.4 mi warmwater habitat. Nearest specially protected stream: the Stillwater river (Englewood dam (RM 9.0) to the mouth), 3.4 mi away, a Superior High Quality Water. 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 Mad River (Macochee creek (RM 51.75) to the mouth), 6.5 mi away, as Outstanding State Water for recreation.

PFAS in the river (Ohio EPA large river survey): at Stillwater R. At Irvington @ Dog Leg Rd., 3.4 mi away, the water carried 80.77 ng/L of total PFAS (PFOA 2.1, PFOS 0.8 ng/L); fish fillets held 38.385 ng/g in bluegill and 12.449 ng/g in catfish (PFOS 26 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 Montgomery County used about 97 metric tons of pesticide active ingredient, 208 kg per square mile, 45th of Ohio's 88 counties. Largest: glyphosate 33 t, atrazine 14 t, metolachlor 8 t, acetochlor 6 t, 2,4-D 6 t. Atrazine, the corn herbicide, is the pesticide that most often shows up in Ohio tap water after spring rains; this county used 14 t of it.

Farms (2022 Census of Agriculture): 789 farms work 118,582 acres of Montgomery County, with 35.7% of its land in cropland, 150 acres to a farm. 8,722 cattle, 4,066 laying hens, 1,149 broilers, 90 turkeys; 39,369 acres of corn and 49,994 of soybeans. Sales $118 million, 12% 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.

ZIP codes and subbasins do not share boundaries, so this ZIP is split between them.

H2Ohio: 1 state water-quality project inside this ZIP (Spring Run Conservation Area Wetland Restoration Project); nearest Spring Run Conservation Area Wetland Restoration Project, inland flow-through wetland, funded 2022, completed, 2.5 mi away: The Spring Run Conservation Area Wetland Restoration project restored 22 acres of wetlands that had been historically managed as a golf course. The restoration ...; 2 within 5 miles, 4 within 15. H2Ohio pays for wetlands, farm practices and lead line work to cut the nutrients behind Lake Erie's algae.

Watershed grants: nearest "Restoration of the Stillwater River in Englewood Park" by Five Rivers Metroparks (dam removal, Section 319), 4.3 mi away; 5 within 10 miles (Ohio EPA project lists: Section 319 and GLRI through fiscal 2023, SWIF through 2017).

Road salt: nearest went to City of Clayton (equipment, 2024-2025), 3.4 mi away; 10 in Montgomery 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 Dry Run-Wolf Creek subwatershed; its water runs on through Town of Oakwood-Great Miami River, then Opossum Creek-Great Miami River, then Dry Run-Great Miami River.

In 2015 Montgomery County drew about 89 million gallons a day of fresh water (USGS): 81.1 million for public supply (100% from wells, 522,900 people served at 47 gallons a person a day at home), 0.1 million for power plant cooling, 3.6 million for industry, 2.2 million for irrigation, 1.1 million for mining; 9,400 residents drew their own well water.

EnviroAtlas, Dry Run-Wolf Creek: under 50 acres in the Conservation Reserve Program; 1,623 acres of grain crops; 30 miles of streams (1.3 per square mile); water use of 2.4 million gallons a day for homes; 40.4 inches of rain and snow a year; 11.2 kg of nitrogen per hectare falling from the air each year; farm nitrogen of 0 kg per hectare a year as manure and 8.4 kg as synthetic fertilizer; 3% of the farmland sits on drained hydric soils; potentially restorable wetlands on farmland cover 4% of the subwatershed; 27% of the land is paved or roofed; 24% of the stream banks keep natural cover (EPA EnviroAtlas national metrics, 2010s vintages).

Stream permits: none 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; 1% drains toward high-quality waters farther down and might qualify for the Army Corps' blanket nationwide permits after a field screening and 99% can use those nationwide permits outright (Ohio EPA 401 nationwide permit eligibility map).

Caveat

9 of the ten years had fewer than 12 months reported by the permit office; the Census Bureau estimates the missing months, so those counts are partly or wholly imputed

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.

On the market (Realtor.com, August 2026): median asking price $179,900, $118 per square foot for a typical 1,578 sq ft listing; 18 active listings, 8 new this month; listings spend a median 46 days on the market; 28% 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.

Local taxes

Trotwood-Madison City

37.5 effective mills (60.5 gross); $2,627 a year on a $200,000 home. Operating 20.9, bonds 8.6, improvements 1.9, inside millage 6.2.

Municipal income tax

Trotwood 2.75%. Charged on wages and business profits where you work and, after credits, where you live.

School district income tax

Trotwood-Madison City none. About a third of Ohio districts levy one.

Sales tax

7.5% combined rate in Montgomery County: Ohio's 5.75% plus county and transit levies.

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.

Owners

county 19, state 6

Rated poor

Autumn Leaf Drive over Dry Run (1934, 1,000 a day); Seybold Rd M0019 over Poplar Run (1900, 120 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

Driving

about 192K vehicle-miles a day on the 304 counted segments inside the ZIP; the typical segment carries 4,808 vehicles

Busiest local road

county road 26, 11,619 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: 13 people died in 11 crashes inside this ZIP in 2020 to 2024 (1 cyclist, 1 motorcyclist); 2 involved a drinking driver and 5 happened in the dark. That is 18.1 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)

Drought (U.S. Drought Monitor): since 2020 Montgomery County has spent 32 weeks in moderate drought or worse, 3 of them severe or worse (most recently 3 weeks in 2024), and 86 weeks at least abnormally dry. The worst since 2000 was extreme drought in 2024/09; 7% of all weeks since 2000 were in drought. As of 2026-09-01: no drought.

Long run (NOAA, Montgomery County): the average year ran 53.4 °F over 1996 to 2025 against 51.3 °F over 1901 to 1930, 2.1 °F warmer (2.0 °F warmer than 1951 to 1980); the warmest year on record was 2024 at 56.4 °F, and 2025 came in at 53.3 °F. Precipitation averaged 42.0 inches a year lately against 39.5 a century ago, 6% more; the wettest year was 2011 with 57.9 inches, and 2025 brought 41.2. More rain in bigger bursts is what strains storm sewers and septic fields.

Stations: Dayton Mcd (6 mi, temperature and precipitation and snowfall; 10 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.

Air standards

Montgomery County is a maintenance area for fine particulate (1997) (Dayton-Springfield, 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.

Spills and releases

What spilled

diesel and fuel oil (4), unidentified material or sheen (2), other chemicals (2)

Largest

about 180 gallons of oil transformer non pcb in 2023, Trotwood

Reached water

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

By year

2021: 4, 2022: 0, 2023: 2, 2024: 1, 2025: 2, 2026: 2

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, 1 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: nearest Tipp Stone Co., Inc. (sand & gravel, Tipp Stone Co., Inc., 17,086 tons sold), 3.6 mi away in Montgomery County; 0 within 3 miles, 5 within 10 (ODNR Industrial Minerals Locations, 2015, which includes surface and underground coal mines).

Soils and septic

Soil

Brookston silty clay loam, fine texture, 0 to 2 percent slopes; Brookston makes up 90% of the unit, 1% slope

Water

poorly drained; hydric (formed under saturated conditions); flooding none, ponding frequent

Septic

Very limited for a leach field under Ohio's rule

Basements

Very limited for dwellings with basements

Farmland

Prime farmland if drained

Elevation

853 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.

Vernal pools: 2 potential high-quality vernal pools covering 2.1 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 Beaver Creek WA (Ohio DNR), 279 acres, 16.1 mi away; 0 within 10 miles.

Mitigation sites: 1 stream or wetland mitigation site inside this ZIP; nearest Great Miami Mitigation Bank, 3.1 mi away (a mitigation bank); 5 within 10 miles. These are wetlands and streams built or restored to replace ones filled under Clean Water Act permits.

Assessed wetland: 1 Ohio EPA study wetland inside this ZIP; nearest Trotwood, a mitigation wetland of 9.8 acres, 0.7 mi away: no ORAM score, plant community index 16 of 100 (surveyed 2001); 1 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

41%: 3% high intensity (downtown blocks, big-box lots), 7% medium (apartments, small-lot houses), 13% low (houses on larger lots), 18% open space (lawns, parks, golf courses, road verges)

Farmland

36%: 28% row crops, 8.1% pasture and hay

Crops 2025

of 3,105 cropped acres, 35% soybeans, 61% corn, 1% wheat and small grains, 2% hay and alfalfa; 1,807 acres of pasture and grass (USDA Cropland Data Layer)

Forest

21%

Water and wetland

0.4% open water, 0.4% wetland

Paved and roofed

13% 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

21% of the ZIP sits under tree canopy

Area

19.8 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%.

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

2 stations within 3 miles, 15 within 8. Inside this ZIP: Trotwood Police Department.

Nearest post office: Trotwood Post Office, 0.7 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.
