ZIP code 43061: Scioto Township and Ostrander

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

55.9 µg/L yearly mean in 2019, the last year in the file (limit 80); worst yearly mean 60.9, highest single sample 95.7; 256 samples from 2012 to 2019

HAA5

35.8 µg/L yearly mean in the last year sampled (limit 60); worst yearly mean 37.8, highest sample 58; 256 samples

Plants

Del-co Water Company, Inc. runs 4 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 4, not only Del-Co Olentangy Water Treatment Plant, which serves this ZIP; a sample over a limit may be from another plant

Nitrate

highest of 225 samples was 2.3 mg/L as nitrogen (2015; limit 10); 1.86 in 2019, the last year sampled. Nitrate above 10 is unsafe for infants

Arsenic

not detected in 31 samples (limit 10)

Solvents and fuels

benzene, carbon tetrachloride, 1,2-dichloroethane, trichloroethylene, tetrachloroethylene, vinyl chloride not detected in 28 samples

Bacteria

1 of 11,459 routine tap samples (0.01%) tested positive for total coliform in 2012 to 2019, 1 of 1,440 in 2019; E. coli found in 1 of 2 tap samples tested for it. Coliform itself is a warning sign; E. coli means sewage or manure reached the water

Farm chemicals

atrazine in 55 of 57 samples, highest 1.55 µg/L (limit 3); alachlor in 1 of 57 samples, highest 0.6 µg/L (limit 2)

Metals

barium in 23 of 31 samples, highest 34 µg/L (limit 2,000); chromium, cadmium, mercury, selenium, thallium not detected in 31 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

11 samples in 2023 to 2024 at the entry point to the distribution system: PFBA 10.7, PFHxA 8.7, PFPeA 6.3 ng/L

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 2024-04 (Ohio EPA statewide sampling status map)

Firefighting foam: 3 fire departments or other holders in Delaware County registered 355 gallons of PFAS-based AFFF foam with Ohio EPA, 165 gallons in opened containers; the state is collecting it for disposal so it is never sprayed again.

Lithium: found in 2 of 10 UCMR 5 samples at Del-co Water Company, Inc., highest 12.9 µg/L (detections averaged 12.6), last sampled 2024. 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 2024-12

Highest since 2016

5.9 ppb (2018-12); never above 10 ppb in 3 periods

Service lines

56,197 inventoried: 9 lead, 19 galvanized needing replacement, 14,186 unknown, 41,983 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: 16% of the homes here were built before 1960 and 9% before 1940, when lead service lines, lead solder and lead paint were common; 31% 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, lime softening, powdered activated carbon, sand or media filtration.

Measured fluoride: 1.04 mg/L on average at the plant's entry points in 2019 (in the range dentists aim for); samples ran from 0.68 to 1.2 mg/L across 31 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 Delaware 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

no microcystin detected at the intake

Treated water

never detected after treatment

Monitoring

631 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.

Bedrock

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

Setting

Limestone; water table 30-50 ft down, 4-7 in/yr recharge, clay loam soil (hydrogeologic setting 7Ac); pesticide index 136

Karst

71 karst and spring points in ODNR's inventory inside the ZIP (58 field-verified), 1.6 per square mile

Aquifers

97% of wells in bedrock, 3% in sand, gravel and other unconsolidated material; typical well drilled 1995, 297 since 2000; uses: Domestic 773, Agric/Irrig 45

Geology

64% 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; 57 field-verified sinkholes and 14 probable sinkholes inside the ZIP, where surface water can pour straight into the aquifer; 2 verified springs (Ohio EPA and ODNR Geological Survey)

Injection wells

1 Class V injection well on Ohio EPA's books inside this ZIP (1 active): 1 other; these put fluids underground above or into drinking water aquifers

Water table

DL-3 OH monitoring well (ODNR), 9 mi away: water 34.1 ft below ground on 2026-07-15; averaged 33.1 ft in 2015 to 2019 and 34.4 ft over the latest year, so the table is running about 1.3 ft lower; range 27.3 to 35.7 ft over 4,056 readings since 2015

Nitrate risk

EPA researchers put the chance that a public water system in the Blues Creek subwatershed exceeds the nitrate limit at 17% if it draws on groundwater and 34% 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 Delaware City PWS (Delaware County), 8.5 mi away: 250 ft deep in limestone or dolomite (DCL undifferentiated Salina aquifer); bedrock 19 ft down; wells there yield 5 to 25 gallons a minute; sampled on the standard cycle. 6 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; 57 field-verified and 14 probable sinkholes inside the ZIP, 2 verified springs; nearest verified sinkhole 1.6 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 117 (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

0.105 million gallons a day design flow

Compliance

0 of the last 12 quarters with a violation; no open violation

Other discharge permits: 1 facility inside this ZIP other than sewage plants holds a Clean Water Act permit (factories, water plants, quarries, package plants, storm water).

Sewage sludge: 19 farm fields covering 701 acres inside this ZIP are permitted for spreading treated biosolids, mostly from Upper Olentangy Water Reclamation Center (465 acres), Olentangy Environmental Control Center (177 acres), Ostrander Wwtp (58 acres) (Ohio EPA). Biosolids carry nutrients and, increasingly under scrutiny, PFAS.

Sludge source: 1 permitted biosolids generator is inside this ZIP; nearest Ostrander WWTP, 1.2 mi away; 2 within 10 miles (Ohio EPA).

State water loans: no Ohio EPA revolving-fund project inside this ZIP; the nearest is 4th WTP- Site Prep & Electrical Substation CIP 690600-100002 (Columbus, 2025, $109.1 million), 6.3 mi away.

Sewer planning: this ZIP falls in the Ostrander FPA; 76% of it is assigned to Delaware County as the designated sewage management agency under Ohio's Clean Water Act section 208 plan (generic prescriptions); 5 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.

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: Lower Mill Creek (not supporting); Moors Run-Scioto River (not supporting).

Fish advisories (Ohio EPA): Mill Creek (Marysville) (State Route 36 to mouth (Scioto River) (Union County)): smallmouth bass one meal a month, saugeye two meals a week (mercury); Bokes Creek (All waters (Logan County)): smallmouth bass one meal a month (mercury); Scioto River (Ostrander Road (Warrensburg) to Greenlawn Dam (Columbus)): saugeye one meal a month, flathead catfish one meal a month (PCBs, mercury). Statewide, every other fish is one meal a week because of mercury.

Nearest stream assessment (Ohio EPA): Blues Creek N Of Ostrander @ Ostrander Rd. on the Blues Creek, 0.7 mi away, draining 34 square miles: non attainment of its warmwater use; fish IBI 33 of 60 (2012); bugs rated marginally good; habitat QHEI 66 of 100. 11 assessed sites inside the ZIP, 6 within 3 miles, 51 within 10. Scores above about 40 (IBI), 36 (ICI) and 60 (QHEI) mean a healthy warmwater stream.

Stream designations (Ohio EPA water quality standards): 38.1 miles of designated streams cross this ZIP: 38.1 mi warmwater habitat. Nearest specially protected stream: the Olentangy river (Delaware dam (RM 32.35) to Old Wilson Bridge road (RM 11.45)), 7.2 mi away, an Outstanding State 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 Scioto River (Mill creek above O'Shaughnessy reservoir (RM 155.4) to the mouth), 3.6 mi away, as Outstanding State Water for recreation.

PFAS in the river (Ohio EPA large river survey): at Scioto R. Just S Of Klondike, Adj. Klondike Rd., 3 mi away, the water carried 70.93 ng/L of total PFAS (PFOA 3.2, PFOS 2.2 ng/L); fish fillets held 43.31 ng/g in bluegill and 24.06 ng/g in catfish (PFOS 20 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 Delaware County used about 145 metric tons of pesticide active ingredient, 316 kg per square mile, 37th of Ohio's 88 counties. Largest: glyphosate 57 t, metolachlor 17 t, atrazine 17 t, acetochlor 7 t, 2,4-D 5 t. Atrazine, the corn herbicide, is the pesticide that most often shows up in Ohio tap water after spring rains; this county used 17 t of it.

Farms (2022 Census of Agriculture): 728 farms work 130,937 acres of Delaware County, with 39.8% of its land in cropland, 180 acres to a farm. 2,157 cattle, 22,126 hogs, 4,349 laying hens, 439 broilers, 21 turkeys; 29,900 acres of corn and 72,838 of soybeans. Sales $133 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.

Road salt: nearest went to Concord Township (equipment, 2024-2025), 6.3 mi away; 2 in Delaware County. H2Ohio pays for brine makers, calibrated spreaders and covered salt barns so less chloride reaches streams and wells.

Watershed plan: the Blues Creek subwatershed around this ZIP's center has an Ohio EPA-approved nine-element nonpoint source plan (2024), the blueprint that makes its farms, streambanks and communities eligible for federal Section 319 runoff grants.

The population center sits in the Blues Creek subwatershed; its water runs on through Lower Mill Creek, then Moors Run-Scioto River, then O'Shaughnessy Dam-Scioto River.

In 2015 Delaware County drew about 24 million gallons a day of fresh water (USGS): 19.7 million for public supply (11% from wells, 182,400 people served at 81 gallons a person a day at home), 1.2 million for irrigation, 2.1 million for mining; 10,600 residents drew their own well water.

EnviroAtlas, Blues Creek: over 1,000 acres in the Conservation Reserve Program; 14,613 acres of grain crops; 70 miles of streams (1.9 per square mile); water use of 250 thousand gallons a day for homes and 15 thousand for farms; 38 inches of rain and snow a year; 10.9 kg of nitrogen per hectare falling from the air each year; farm nitrogen of 0 kg per hectare a year as manure and 47.8 kg as synthetic fertilizer; 22% of the farmland sits on drained hydric soils; potentially restorable wetlands on farmland cover 39% of the subwatershed; 1.8% of the land is paved or roofed; 31% 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, so stream crossings and fills here can use the Army Corps' blanket nationwide permits under Ohio EPA's standing 401 certification (Ohio EPA 401 nationwide permit eligibility map).

Zillow's typical home value here is $512K (2026-07), up 2% over the year, up 25% over five years and up 88% over ten.

On the market (Realtor.com, August 2026): median asking price $559,950 (up 8.2% in a year), $236 per square foot for a typical 2,079 sq ft listing; 8 active listings, 4 new this month; listings spend a median 29 days on the market (down 38% from a year earlier); 50% 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

Ostrander 1% (24% 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

Buckeye Valley Local 1% (82% of residents), Fairbanks Local 1% (14% of residents), North Union Local 1% (4% of residents). Voted by the district and collected with the state income tax.

Sales tax

7% combined rate in Delaware 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.

Rail crossings

Delaware County has logged 3 rail accidents since 2010, 3 of them derailments (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.

Rated poor

Ostrander Rd. over Scioto River (1968, 665 a day); Tyler Rd. over Bokes Creek (1984, 324 a day) and 1 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.

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: 5 people died in 5 crashes inside this ZIP in 2020 to 2024 (1 motorcyclist); 1 involved a drinking driver and 2 happened in the dark; most on SR-257 (2). 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 Delaware County has spent 22 weeks in moderate drought or worse, 5 of them severe or worse (most recently 5 weeks in 2024), and 85 weeks at least abnormally dry. The worst since 2000 was severe drought in 2024/11; 4% of all weeks since 2000 were in drought. As of 2026-09-01: no drought.

Long run (NOAA, Delaware County): the average year ran 52.2 °F over 1996 to 2025 against 50.5 °F over 1901 to 1930, 1.7 °F warmer (1.7 °F warmer than 1951 to 1980); the warmest year on record was 2024 at 55.2 °F, and 2025 came in at 51.9 °F. Precipitation averaged 41.1 inches a year lately against 38.7 a century ago, 6% more; the wettest year was 2011 with 55.1 inches, and 2025 brought 35.9. More rain in bigger bursts is what strains storm sewers and septic fields.

Stations: Marysville (6.7 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.

Air standards

Delaware 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.

Toxic releases

Where it went

0 lb to the air, 0 lb to surface water, 0 lb to land or underground injection; another 0 lb was shipped off site for disposal or release

Chemicals

Polycyclic aromatic compounds under 1 lb (carcinogen), Benzo[g,h,i]perylene under 1 lb

Spills and releases

What spilled

diesel and fuel oil (3), oils and hydraulic fluid (1), industrial, farm and drilling chemicals (1)

Largest

about 20 gallons of fuel diesel / diesel fuel (vehicle on or off road) in 2024, Ostrander

Reached water

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

By year

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

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, 18 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: 1 working operation inside this ZIP in 2015 (Ostrander Quarry, limestone); nearest Delaware Plant (limestone, National Lime & Stone Co., 2,970,000 tons sold), 3.2 mi away in Delaware County; 0 within 3 miles, 2 within 10 (ODNR Industrial Minerals Locations, 2015, which includes surface and underground coal mines).

Soils and septic

Soil

Glynwood clay loam, end moraine, 2 to 6 percent slopes, eroded; Glynwood makes up 85% of the unit, 4% slope

Water

moderately well drained; flooding none, ponding none

Septic

Somewhat limited for a leach field under Ohio's rule (very limited under the national rule)

Basements

Very limited for dwellings with basements

Farmland

All areas are prime farmland

Elevation

945 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.

Parks and public land

Mill Creek Golf Club

private park, 111 acres inside the ZIP

Blues Creek Preserve

state conservation area, 45 acres inside the ZIP

Nearest state park: Delaware State Park, 9.4 mi.

Protected land: 0.5% of this ZIP (157 acres) is in the USGS Protected Areas Database inventory of fee-owned parks, preserves and recreation land (public agencies, land trusts, and private clubs, camps and utility land, as their owners report it): 111 acres private, 46 acres local. Largest: Mill Creek Golf Club (private owner), 111 acres; Blues Creek Preserve (county), 45 acres. 1% of the ZIP is protected land open to the public.

Trails: no built named trail crosses this ZIP; nearest is the Ohio to Erie Trail, 12.7 mi from the ZIP's center (ODNR statewide trails inventory).

Open access as reported by each owner; local inventories vary, so a golf course or school field can be listed and a new park missed.

Wetlands

160 acres forested/shrub wetland, 142 acres pond, 29 acres emergent wetland. Largest single wetland: 15 acres of freshwater forested/shrub wetland.

Vernal pools: 42 potential high-quality vernal pools covering 16.1 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 O'Shaughnessy Reservoir Park (City of Columbus), 12 acres, 3.8 mi away; 1 within 10 miles.

Mitigation sites: nearest Green Meadows Drive Extension, 6.7 mi away (a permittee-responsible site under an environmental covenant); 8 within 10 miles. These are wetlands and streams built or restored to replace ones filled under Clean Water Act permits.

Assessed wetland: nearest N220_027, a wetland, 3.7 mi away: ORAM 79 of 100 (category 3), plant community index 87 of 100 (surveyed 2010); 12 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

8.3%: 1% medium (apartments, small-lot houses), 3% low (houses on larger lots), 4.0% open space (lawns, parks, golf courses, road verges)

Farmland

76%: 63% row crops, 13% pasture and hay

Crops 2025

of 16,612 cropped acres, 62% soybeans, 24% corn, 3% wheat and small grains (plus 3% wheat followed by soybeans, counted under soybeans), 6% hay and alfalfa, 6% vegetables, orchards, fallow and other crops; 5,292 acres of pasture and grass (USDA Cropland Data Layer)

Forest

13%

Water and wetland

0.6% open water, 0.6% wetland, 1.2% barren (quarries, strip mines, beaches)

Paved and roofed

2% 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

12% of the ZIP sits under tree canopy

Area

45.4 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%.

Commuting area: USDA classes this ZIP as a metropolitan suburb with heavy commuting to the core (rural-urban commuting area code 2 of 10, 2020 edition).

Race shares follow the Census categories, with Hispanic origin counted separately from race. Five-year averages centered on 2022. Moves count people on tax returns whose address changed county, so students and the very poor are undercounted.

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).

History

Scioto Township 49% Ostrander 24%

Before the settlers

Scioto Township's own chapters in both the 1880 and 1908 county histories describe the Wyandot directly and specifically. Boke's Creek, the township's principal tributary stream, 'was named for a Wyandot chief,' per the 1908 history. The 1880 county history adds that when white settlers first arrived, 'they found the Indians friendly, and gained from them information which in those days was very valuable, namely, the location of the Salt Licks, the fords in the river, and the haunts of the water-fowl and deer'; the same source recalls that early travel through the region followed routes laid out 'over Indian trails.' Writing in 1880, the county historian noted that the Wyandot had by then been removed from Ohio entirely, following the 1795 Treaty of Greenville land cession and the further nineteenth-century treaties that culminated in the Wyandot's 1843 removal from their Upper Sandusky reservation, the last Native nation to leave the state as a body. No specific village, mound or burial site within Scioto Township itself is named in the sources consulted; for the county's other documented Native sites see the county file.

How Scioto Township, Delaware County began

Scioto Township, on Delaware County's western edge along the Scioto River, was established by petition on December 7, 1814 and takes its name from the river itself, which the 1908 county history calls 'a corruption of the Indian name Scionto, applied to the river by the Wyandots.' Welsh immigrant Richard Hoskins settled at the mouth of Boke's Creek in 1806, one of the township's first arrivals, and early settlers relied on the resident Wyandot for knowledge of salt licks, river fords and game before the tribe's removal from Ohio. The railroad-era village of Ostrander, platted in 1852 and named for a surveying engineer, eclipsed the earlier settlement of Edinburg (Fairview) and remains the township's principal community today.

Settled 1806, incorporated 1814-12-07; by petition granted by the Delaware County commissioners. source

Stories

What the Wyandot Taught the Settlers

When Richard Hoskins and the small band of families who followed him reached the mouth of Boke's Creek in the first decade of the 1800s, they were not moving into unknown wilderness. The Wyandot who lived and hunted along the Scioto River were, by the 1880 county history's account, friendly toward the new arrivals and shared knowledge that made frontier survival possible: where to find the salt licks essential for preserving meat and curing hides, where the river could be safely forded, and where deer and waterfowl could reliably be found. Boke's Creek itself carries the name of a Wyandot chief. Settlers reached the township at all mostly by following existing Indian trails, since no roads yet existed into the Northwest Territory beyond paths cut to supply the frontier forts. By the time the county history was written in 1880, its author noted flatly that the Wyandot were gone from Ohio, a people it described only as having vanished west — a stark measure of how completely the 1795 Treaty of Greenville and the treaties that followed it had displaced the very people whose knowledge had made settlement possible. source

A Village Named for an Engineer

Before Ostrander existed, the township's first platted village was called Fairview and then Edinburg, laid out on a scenic rise north of where Ostrander now stands. For a time it grew slowly but steadily, and its founders expected it to become an important town. Everything changed when a new railroad was surveyed through a different part of the township: I. C. Buck platted 104 lots in 1852 on the line the engineers had chosen, and named the new village Ostrander after the man who had surveyed it. Edinburg's growth stalled and eventually reversed; by the time the 1908 county history was written, the once-promising village survived only as 'a few houses in the neighborhood where the Gabriels live,' while Ostrander incorporated in 1875 and became the township's lasting commercial center. source

The Burned Pond

In the western part of the township, on land later farmed by John W. Eddleblute and Acel Larcum, there once stood a substantial pond and surrounding swampland. Settlers drained it to make the ground farmable, but that left a tangle of dead vegetation to clear. Their solution was fire: they set the drained swamp alight, and it burned for so long, and so persistently, that it took a considerable time to fully extinguish. The road running north and south past the site took on a new name from the episode, the Burned Pond Pike, and the land it named proved, once cleared, to be among the richest farmland in the township. source

Delaware County

Delaware County was created by the Ohio General Assembly on February 10, 1808, out of Franklin County, and named, like its seat, for the Lenape (Delaware) people. The seat, Delaware, was platted that same year by Moses Byxbe and Henry Baldwin on the west bank of the Olentangy River, on the ground of a former Mingo village, Pluggy's Town, and around a sulphur spring that grew into a failed resort hotel before becoming, in 1842-44, the seat of Ohio Wesleyan University. The county gave the country a president, Rutherford B. Hayes, born in Delaware in 1822, and gave up more than half its original territory to the later counties of Union, Marion and Morrow. Four twentieth-century reservoirs - O'Shaughnessy, Delaware Lake, Hoover and Alum Creek - now cover parts of the county's river valleys, the last of them drowning the Underground Railroad settlement of Africa along with a run of Adena burial mounds. Since 1990 Delaware County has been one of Ohio's fastest-growing counties, its population more than doubling as Columbus's northern suburbs - Powell, Lewis Center, Orange Township - filled in what were, within living memory, farm townships.

Settled 1807-12-02 (John Beard buys 624 acres on the Olentangy's west bank, the first settlement within present Delaware Township), platted 1808-05-09 (Moses Byxbe and Henry Baldwin plat the town of Delaware on the Olentangy's west bank, replacing an unrecorded east-bank plat of March 7, 1808), incorporated 1808-02-10 (county organized by act of the Ohio General Assembly); 1816 (town of Delaware incorporated, the first incorporated town in the county); by Ohio General Assembly, 'An Act Establishing the County of Delaware,' organized out of Franklin County; first officers elected that spring: John Welch, Avery Powers and Ezekiel Brown, commissioners; Rev. Jacob Drake, treasurer; Dr. Reuben Lamb, recorder; Solomon Smith, sheriff; Azariah Root, surveyor. source

The name. Delaware County and its seat were both named for the Lenape, whom English speakers called the Delaware after Virginia's colonial governor, Lord De La Warr. Moses Byxbe and Henry Baldwin, who owned the land, chose the name for their new town in 1808, on ground that had itself been a Mingo rather than a Lenape village (Pluggy's Town); the county took the same name when the legislature organized it that February, following a common pattern in early Ohio of naming counties for the Native nations displaced from them rather than for the people who had actually lived on the specific site.

The county seat. Delaware was platted in 1808 by Moses Byxbe and Henry Baldwin on the west bank of the Olentangy River, on and around the sulphur spring and the site of the former Mingo village Pluggy's Town; an earlier plat on the east bank, agreed to in March 1808, was never recorded and was abandoned for the surviving west-bank plat filed that May. Special commissioners fixed Delaware as the permanent county seat in March 1808, over a rival bid by Byxbe himself to make his own land at 'Berkshire Corners' (near present Ostrander) the seat instead; Delaware then narrowly lost a second, larger contest in 1812, when the legislature chose the newly platted Columbus over Delaware as Ohio's state capital by a single vote. The town was incorporated in 1816, the first incorporated town in the county.

County stories

Pluggy's Town

Before there was a Delaware, there was Pluggy's Town, a Mingo village on a horseshoe bend of the Olentangy founded around 1772 by a Mohawk-born chief the settlers called Pluggy. He built a mixed following of Mingo, Shawnee and Wyandot fighters, numbering perhaps 300 by one account, and used exaggeration and rumor as readily as raids to keep the frontier on edge; Virginia officials complained of 'the obstinate and wicked Disposition of the said Indians of Pluggy's Town.' Through 1776, encouraged and supplied by the British commander at Detroit, Henry Hamilton, Pluggy led repeated raids into Kentucky, killing the frontiersman John Gabriel Jones among others. Virginia's government prepared an expedition to strike Pluggy's Town itself in 1777, but Governor Patrick Henry called it off, worried his militia could not tell Pluggy's warriors from the neutral Delaware and Shawnee living nearby. The precaution came too late to matter to Pluggy: on December 29, 1776, storming McClelland's Station in Kentucky, he was shot dead by four of the fort's defenders. His town on the Olentangy outlived him by three decades before Ohio settlers arrived to found Delaware on the same ground. source

The Fight for the County Seat

Moses Byxbe arrived in central Ohio in 1804 already planning to make himself the center of it: he bought land at a place called Berkshire Corners and told prospective settlers it would become not just the Delaware County seat but, if his luck held, the capital of Ohio. Many came on that promise. Then, in 1808, Byxbe quietly bought a half-interest in two military-district sections on the Olentangy from Henry Baldwin of Pittsburgh and abandoned Berkshire overnight for a new town he and Baldwin platted on the river - first on the east bank in March, then, for reasons the record does not explain, on the west bank that May. The sulphur spring nearby gave his new site, in the words of the county's first historians, 'prestige to the location as the probable site of a famous watering-place,' and despite a bitter protest from the Berkshire settlers he had recruited and then abandoned, special commissioners fixed the permanent county seat at Delaware in March 1808. Byxbe's luck ran out only once more: when the legislature chose a site for the new state capital in 1812, Delaware lost to the still-unbuilt town of Columbus by a single vote. source

The Medicine Waters and the Mansion House

Long before Ohio Wesleyan University existed, its ground was known for a sulphur spring that Native visitors, by one settler's account, called the 'Medicine Waters,' a place where buffalo were said to have gathered as readily as people. Moses Byxbe and Henry Baldwin donated four acres around the spring to the village of Delaware in 1828, and in 1833 a newcomer named C. W. Kent proposed leasing the land to build a spa hotel. Kent had no architect nearer than Columbus, so a local judge, Powell, drew the plans himself; the resulting Mansion House opened in 1834, and Kent promptly traveled to New York and bought $10,000 in furnishings on the strength of owning the springs - only to have his creditors seize the goods in Columbus before they ever reached Delaware. The hotel sat empty for two years, ran as a health resort under new management from 1836 to 1840, and, having never quite worked as a business, was then sold to the Methodist Church. Three or four years later, the college that became Ohio Wesleyan University opened inside the old hotel building, which still stands today as Elliott Hall. source

Ten Weeks Fatherless

Rutherford Hayes and Sophia Birchard Hayes moved from Vermont to Delaware, Ohio, part of the wave of settlement that followed the War of 1812. Rutherford Sr. died on July 20, 1822, weeks before his wife gave birth; when their son arrived on October 4, 1822, on East William Street, she named him for the father he never met, Rutherford Birchard Hayes. Sophia raised him and his older sister Fanny alone, never remarrying, in a county that was still mostly recent farmland surveyed out of the old military lands. That infant grew up to practice law, serve as a Union major general, and become the 19th President of the United States in 1877. Delaware's high school now bears his name, and a statue raised by public subscription was dedicated at William and Sandusky streets on October 4, 2019, Hayes's 197th birthday. source

The Welsh of Radnor

David Pugh and Henry Perry, both born in Wales, were the first white settlers in what became Radnor Township, arriving in 1803, years before Delaware County itself existed. Pugh had bought a full section of land from a Dr. Jones of Philadelphia and, in 1805, platted 150 acres of it into blocks and lots as a town he called New Baltimore, convinced it would grow into a great city and make his name. It never did: in the fall of 1810, Thomas Warren, newly arrived from Pennsylvania, bought the whole plat and turned it back into a farm. Other Welsh families - Lodwig, Jenkins, Watkins, the Joneses and Philipses - followed Pugh into Radnor over the next decade, planting a community whose name still echoes a county in Wales, even after Pugh's paper city vanished back into farmland. source

Drake's Defeat

In the summer after Hull's surrender in 1812, Captain William Drake led a company of mounted rangers out from Delaware County toward Lower Sandusky, and on their first night in camp, bored and mischievous, he slipped into the woods, fired his gun, and came running back yelling that Indians were attacking. His own sentries took up the cry; his lieutenant, more devoted to his legs than his weapon, bolted into the forest and ran some ten miles before daybreak, arriving bareheaded at the Radnor settlement swearing the whole company had been massacred but him. Panic spread through Delaware within hours: families fled on horseback, in wagons and on foot toward Worthington, Franklinton and even Chillicothe; in the confusion one family lost a toddler bounced from a moving wagon (he was found safe), and one woman, running back for her baby, grabbed a stick of firewood by mistake and fled with that instead. Drake, oblivious, marched his company on to Sandusky as ordered and finished the campaign without incident, while the settlers who had scattered took days to trickle home and count their losses. He was later elected an associate judge, and the county's first historians note dryly that he was 'never wholly forgiven' by some of the people his joke had put to flight. source

Africa, Under the Reservoir

In the 1820s, Samuel Patterson and other antislavery farmers settled a community on Alum Creek's east side that they first called East Orange; when a pro-slavery neighbor mocked their politics by nicknaming it Africa, the settlers kept the name. Patterson hid freedom-seekers in his own home and brought abolitionist speakers to the local Wesleyan Methodist church, and in 1859 about thirty formerly enslaved people from a North Carolina plantation, the Alstons, settled in Africa outright, working the antislavery farmers' land and joining their congregation as free residents on a station of the Underground Railroad's Sycamore Trail. The community was still there, sixteen people strong, when it appeared on the television show Hee Haw in 1973. It did not survive the decade: the U.S. Army Corps of Engineers had already begun damming Alum Creek in 1970, and by 1974 Africa's houses, farms and stretch of the Sycamore Trail lay under the new reservoir alongside five relocated cemeteries and the Adena burial mounds archaeologists had raced to excavate first. A 0.75-mile Heritage of Freedom Trail near the Galena boat ramp, opened in 2024, is the only place left to walk the ground where Africa stood. source
