Union County in central Ohio is organized around Marysville, with Richwood, Magnetic Springs, Milford Center, Unionville Center, Raymond, Plain City, and smaller communities spread across a broad rural landscape. Routes 4, 31, and 33 converge around Marysville, while Route 37 reaches Richwood and Route 42 serves the eastern side. The land is generally higher in the west and northwest and lower toward the east and southeast, where many small streams occupy shallow valleys. High-resolution JPG originals of all four supplied maps are available in the download ZIP for printing and close inspection.
Marysville is the most useful starting point. Richwood lies to the northeast, Magnetic Springs to the east, Raymond to the northwest, Milford Center to the southwest, and Unionville Center to the south. Plain City and New California provide southeastern references near the Franklin County side. The county’s settlement pattern is dispersed, but the road network radiating from Marysville makes the center easy to identify.

Marysville anchors Routes 4, 31, and 33 in the southern-center
The general county map places Marysville slightly south of center and shows the county’s largest developed area. Route 4 runs through the city from the north, Route 31 reaches the same central area, and Route 33 approaches from the west before continuing southeast toward the Columbus side. Rail lines and several local roads also meet near Marysville, reinforcing its role as the county’s administrative and transportation hub.
Richwood is the clearest northeastern town and sits close to Route 37. Magnetic Springs lies farther south and east near Route 347. In the west, Route 47 reaches toward the West Mansfield side, while Raymond provides a useful west-central reference near Route 739. The western road pattern crosses a landscape with fewer large developed areas and many small streams.
Milford Center lies southwest of Marysville, with Route 36 farther south. Unionville Center occupies the southern interior, while Plain City sits near the southeastern county edge close to Routes 161 and 38. New California is northeast of Plain City and southeast of Marysville, and the Union County Airport appears on the eastern side. These places show how the county extends from Marysville into several separate rural corridors rather than one continuous urban strip.
Union County’s official government offices are centered in Marysville, matching the strong central role visible on the map. The static road layer is intended for geographic orientation, not live traffic, construction, or travel-time information, so current driving conditions should be checked separately.
Five highlighted communities reveal the spacing around Marysville
The city-distribution view highlights Marysville, Richwood, Milford Center, Magnetic Springs, and Unionville Center. Marysville is the central-southern anchor. Richwood lies northeast, Magnetic Springs east, Milford Center southwest, and Unionville Center south. With most secondary road labels removed, the large gaps between these smaller communities become much easier to compare.
The CITY CONNECTIONS panel prints values beside the five names, but those figures belong to the supplied map and are not reused here as current official population estimates. Census reference years can differ from the map’s source date. The stable information is geographic: Marysville anchors the center, Richwood the northeast, Magnetic Springs the east, Milford Center the southwest, and Unionville Center the south.
Returning to the road map adds the connections. Route 37 helps locate Richwood, Route 347 identifies the Magnetic Springs area, and the southwest road network leads toward Milford Center. Routes 38 and 161 help orient the southern portion near Unionville Center and Plain City. Marysville is noticeably larger and more connected than the surrounding settlements, so it remains the best reference point across all views.
Bokes Creek and Little Darby Creek lead a dispersed stream network
Union County’s water map is defined by many medium and small streams rather than one dominant river. Bokes Creek crosses the northwestern and north-central interior, with Fulton Creek, Rush Creek, Powder Lick Run, and Brush Run nearby. Richwood Lake provides a small but distinct waterbody reference east of the northern interior.
Mill Creek appears in the west-central area, while Buck Run follows a longer course through the southern half. Along the southern boundary, Proctor Run, Treacle Creek, and Little Darby Creek occupy neighboring drainage corridors. These are relatively narrow channels, but together they give the agricultural landscape a more intricate pattern than the road map alone suggests.
The southeast contains Sugar Run, North Fork Indian Run, and Robinson Run, all associated with the lower terrain toward the Franklin and Delaware county side. The map therefore divides naturally into a northern Bokes Creek network, a southern set of Buck Run and Little Darby tributaries, and smaller eastern streams. Large reservoirs do not dominate the supplied water layer.
The City of Marysville maintains an upground reservoir and park on Raymond Road as part of its local water and recreation system, along with an extensive city park network. That provides useful local context for water resources around the county seat. The supplied water map itself is a geographic reference and should not be used as a flood-hazard map, legal water-boundary record, current depth or flow chart, drainage-engineering plan, or navigation product.
Elevation from about 270 to 348 meters falls from the west toward the east
The elevation legend reports an actual county range of about 270 to 348 meters, with a mean near 304 meters. The highest brown terrain is concentrated along the western and northwestern side. Moving eastward, colors shift through yellow and light green into broad green lowlands, with the east and southeast generally lower than the west.
The western boundary contains the broadest high ground. The northwest is also elevated, but Bokes Creek and smaller tributaries create lower green cuts through the upland. Around Raymond and the western interior, the surface descends gradually toward Marysville while local streams create additional shallow valleys.
East of Marysville, lower colors become much more common. The Richwood-to-Magnetic Springs side is generally lower than the far west, and the Plain City–New California area in the southeast contains some of the broadest green terrain. Little Darby Creek and the southeastern runs follow these lower corridors, reinforcing the overall west-to-east decrease.
Brown represents the high end of Union County’s locally scaled legend, not mountain terrain. The elevation image is useful for county-scale comparison but not site engineering. Exact parcel elevations, road grades, drainage design, and construction measurements should come from original USGS elevation data or a professional survey.
Use Marysville to compare the high west with the lower southeast
Keeping Marysville fixed while switching views is the fastest way to connect the county’s geography. The general map shows Routes 4, 31, and 33 radiating from the city, the city view places Richwood and Milford Center on opposite sides, the water map separates the Bokes Creek system from the southern streams, and the elevation layer shows terrain dropping toward the east and southeast.
Richwood works well as a northeastern reference. Route 37 locates the town, while Richwood Lake and Rush Creek provide nearby water landmarks. The elevation map shows lower ground east of much of the western interior, and the northern streams occupy broad, shallow valleys rather than deeply cut ravines.
Milford Center and Plain City provide a useful southern contrast. Milford Center lies closer to moderately elevated southwestern terrain, while Plain City and New California sit within broader low green areas toward the southeast. Little Darby Creek, Sugar Run, and nearby tributaries follow that lower part of the county.
Choose the Union County map that fits the task
Use the general county map when you need Marysville, Richwood, Magnetic Springs, Raymond, Plain City, Routes 4, 31, 33, and 37 together. The city-distribution map is cleaner when the goal is comparing the five highlighted communities. Choose the water map for Bokes Creek, Buck Run, Little Darby Creek, Richwood Lake, and the smaller stream network.
The elevation map is the clearest choice for comparing the higher western and northwestern side with the lower east and southeast. The WebP previews on the page are convenient for quick viewing, while the high-resolution JPG originals in the ZIP below are better for printing and zooming into small labels. These maps are regional reference products and should not replace legal parcel records, live navigation, flood determinations, or survey-grade elevation data.
Frequently Asked Questions
How are Marysville and Richwood positioned on the map?
Marysville sits slightly south of the county center, while Richwood is northeast. Route 37 is a useful reference near Richwood, and a broad rural area with many small streams separates the two communities.
Why does the water map show many small streams instead of one major river?
The supplied map shows Bokes Creek, Buck Run, Little Darby Creek, and numerous smaller tributaries spread across a gently rolling agricultural landscape. No single large river dominates the county, so the drainage pattern appears as several separate creek systems.
Can the 270–348 meter elevation range be used for surveying?
No. The elevation map is intended for county-scale comparison of the higher west and lower east. Exact parcel heights, road grades, drainage design, and construction measurements should come from original USGS data or a professional survey.
