Explore Petaluma, California, with this interactive street and satellite map.
This page also offers TOPO MAPS — the official USGS topographic sheets — plus USGS aerial imagery, a labelled USNG grid overlay, a distance and bearing tool, and a GPS grid-reference readout. See How to Use This Map below.
This interactive map shows the street layout and satellite imagery for Petaluma, California. Use the Map and Satellite buttons above to switch between street map and aerial imagery views. Use the + and − buttons to zoom in or out, or scroll your mouse wheel while holding the Control key to zoom. On a touchscreen, use a two-finger pinch gesture. Drag the map to pan to any area of California or beyond.
Click ⛶ Fullscreen to expand the map to fill your screen. To return to the normal page view, press the Escape key, click the ✕ Exit Fullscreen button that appears above the map, or on a mobile device tap the back button (Android) or the close icon (iOS).
TOPO MAPS — NEW. Click the green 🔍 Search Maps button below the map to open a second map with a Base map row offering three choices. OSM is the standard OpenStreetMap street map. Topo shows the official USGS topographic maps from The National Map — contours, hydrography, land cover and shaded relief, the same mapping used for hiking, hunting and back-country navigation in the Adirondacks, the Catskills and the Finger Lakes. Imagery shows USGS aerial photography, mostly 1-metre NAIP. The search box finds any US town, county or landmark by name, so you are not limited to Petaluma.
Reading the map like a paper quad. Click Grid to overlay the U.S. National Grid (USNG), labelled along the edges exactly as a printed topographic sheet is — at normal zoom the squares are one kilometre across, so you can read a six-figure grid reference by eye and judge distance directly off the map. Click Measure, then tap two points, to get the distance between them together with the grid bearing in degrees and mils, the true bearing, and the magnetic bearing to set on a compass.
Click 📍 My position to take a single GPS reading from your device. It marks where you are and reports your position as a USNG grid reference as well as plain latitude and longitude — USNG being the format FEMA and US search and rescue teams work from — with a Copy position button so you can paste it straight into a text message. It takes one reading and stops, rather than tracking continuously, to conserve your battery. Note that map tiles need cell coverage, but a GPS reading does not — your coordinates stay correct even where the map itself cannot load.

Petaluma reveals itself through the steady, rhythmic pulse of the Petaluma River as it carves a slow passage through the valley floor. It lies 8.2 miles south-southeast of Rohnert Park, CA (from Rohnert Park, CA: bearing 155°T), and is situated 9.4 miles north-northwest of Novato. The landscape around Petaluma holds the warmth of the sun in its golden, dry grasses, while the horizon is defined by the distant, hazy blue silhouettes of the Coast Ranges. Three miles to the north, the terrain levels out across Denman Flat, providing a quiet expanse of open space that contrasts with the wooded riparian corridors. Though the Pacific Ocean lies only eleven miles away, the air here feels distinct, often carrying a heavy, salt-tinged moisture that settles over the land when the evening fog begins its inland drift.
Petaluma traces its origins to the legacy of the Coast Miwok people, who long occupied these fertile lands before the arrival of Spanish colonial interests. During the mid-nineteenth century, Petaluma grew rapidly as a vital shipping hub, utilizing the water-borne access provided by the river to transport grain and produce to expanding markets. The architecture of the downtown district remains a physical record of this era, characterized by iron-fronted buildings that survived the seismic shifts of the past. Walking these streets, one senses a continuity of purpose, where the industrious spirit of early merchants has evolved into a modern appreciation for preservation and the careful stewardship of the built environment.
Petaluma maintains a diverse economic base that bridges the gap between traditional agricultural roots and contemporary innovation. While the surrounding countryside continues to support productive farms and dairies, the local infrastructure now hosts a variety of technology and manufacturing firms, alongside a robust service sector. Educational needs are met by a range of local institutions, though the town relies on broader regional networks for its university-level instruction. Water resources remain central to the area's function, with the Petaluma Reservoir serving as a key element of the local utility landscape, ensuring that the rhythm of commerce and daily life remains uninterrupted by the seasonal variability of the climate.
Cultural life in Petaluma centers on the preservation of local history and the celebration of communal identity, frequently expressed through gatherings at Walnut Park. The town hosts several annual festivals that draw visitors to its historic center, while the proximity to Neils Island and the various reaches of the river offers quiet opportunities for those who enjoy the outdoors. For a challenging excursion, many residents look toward the elevation changes found along the Mountain Trail. While no major professional sports franchises call the area home, a deep appreciation for high school and collegiate athletics keeps the local spirit engaged throughout the year. Notable figures such as the creator of the Monopoly board game, Charles Darrow, once found inspiration in the quiet character of Petaluma, leaving a mark on the town that persists in its lingering sense of creative independence.

Search Maps opens a second, independent map. It searches OpenStreetMap for any US town, county or landmark by name; offers USGS topographic maps and USGS aerial imagery as base layers; overlays a labelled U.S. National Grid (USNG) so the map can be read like a printed topographic quad; measures distance and grid, true and magnetic bearings between any two points; and takes a single GPS fix reporting your position as a USNG grid reference and as latitude and longitude. Map tiles require cell coverage, but a GPS position does not, so the coordinates remain correct even where the map cannot load.
Location data is drawn from the USGS Geographic Names Information System (GNIS) and cross-verified against 2020 US Census records by coordinate proximity. Population figures are sourced from the 2020 US Census.
