Explore Alamo, 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 Alamo, 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 Alamo.
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.

Alamo defines the character of Stone Valley with its expansive, sun-drenched landscape that transitions from flat valley floors to the rising terrain of the region. It lies 2.6 miles northwest of Danville, CA (from Danville, CA: bearing 318°T), and is situated 8.8 miles south of Concord. San Ramon Creek meanders through the landscape, acting as a quiet artery that sustains the local flora and fauna throughout the changing seasons. The air here holds a distinct stillness during the golden hour, when the warmth of the day fades into a cool, crisp dusk. Residents often visit Andrew H. Young Park to appreciate the open space that characterizes the immediate surroundings. On the distant horizon, the silhouette of the Coast Ranges provides a constant, grounding presence against the wide sky. Leland Reservoir remains a quiet, shimmering presence just a short distance away, reflecting the shifting colors of the afternoon light.
Agriculture once dictated the rhythm of life in Alamo, though the modern economy has shifted toward professional services and residential stability. Early settlers recognized the fertility of the soil, which supported orchards and grazing lands long before the current suburban infrastructure took root. The expansion of regional transit networks transformed the local landscape, drawing in families who sought a balance between professional ambition and a slower pace of life. Industry now feels less like the clatter of machinery and more like the quiet hum of home offices and local commerce. The legacy of the land remains visible in the large, private lots that maintain a sense of space despite the density of the surrounding region. Alamo preserves a spirit of independence, rooted in a history of agrarian self-sufficiency that informs its current, more polished appearance.
Alamo fosters a cultural character defined by a quiet, understated appreciation for the natural environment and a commitment to maintaining its residential identity. Residents frequently gather for local events that emphasize the importance of neighborly connection, often utilizing the public facilities at Andrew H. Young Park for seasonal activities. The architecture of the region leans toward expansive, individualistic styles that allow for generous gardens and oak-shaded yards. Famous individuals, such as the legendary athlete Joe DiMaggio, once found the privacy and climate of this region to be a welcome respite from the demands of public life. The atmosphere is marked by a deliberate avoidance of the frantic energy found in larger metropolitan centers, favoring instead the steady movement of a community that values its own seclusion. Life in Alamo proceeds with a measured cadence, where the primary focus remains on the preservation of a high quality of life for those who reside within its borders.

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.
