Explore Brentwood, 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 Brentwood, 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 Brentwood.
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.

Brentwood maintains a presence defined by the quiet interplay of open space and the steady expansion of the built environment. It lies 4.6 miles south-southeast of Oakley, CA (from Oakley, CA: bearing 169°T), and is situated 7.8 miles southeast of Antioch. The land here slopes with a subtle grace toward the lower reaches of Lone Tree Valley, where the heavy, golden heat of the afternoons softens the edges of the horizon. Though the Pacific Ocean sits twelve miles away, the air carries a distinct, lingering salt-tide influence that tempers the interior warmth. Sand Creek cuts a modest, rhythmic path through the terrain, providing a natural corridor that anchors the local topography. To the west, the distant silhouettes of the Coast Ranges rise against the sky, their ridges often blurred by the soft, gray drift of evening fog that rolls in as the sun dips low.
Brentwood began as a small agricultural outpost, a place where the soil dictated the rhythm of daily life and determined the fortunes of those who worked the fields. The early settlers saw the potential in the fertile earth, establishing a foundation that favored the orchard and the harvest over the rapid, industrial sprawl seen elsewhere. This history remains visible in the way the streets are laid out, with remnants of agrarian life still echoing in the town’s spatial organization. Over time, the transition from vast tracts of fruit trees to a more residential character has been gradual, preserving a sense of continuity that honors the labor of the generations who first broke the ground. Even as the modern world encroaches, the spirit of that original settlement persists in the deliberate pace of the neighborhood streets and the enduring importance of the harvest season.
Brentwood serves as a vital economic node, balancing a legacy of agriculture with the demands of a modern, service-oriented infrastructure. While many residents commute to larger centers of employment, the local economy benefits from a mix of commercial development and a robust, small-scale industrial base that provides for the immediate needs of the region. Education is supported by a network of public and private institutions that emphasize community involvement and academic rigor, preparing the youth for the complexities of the current workforce. The proximity of the Marsh Creek Reservoir provides a necessary water resource, supporting both the remaining agricultural interests and the domestic needs of the growing population. Life here is facilitated by a grid that connects suburban density to the more open, undeveloped parcels that still define much of the surrounding landscape.
Brentwood Park offers a central gathering space where the social life of the residents finds a quiet, shared expression amidst the trees and open grass. The cultural character of Brentwood is expressed through seasonal festivals that celebrate the local harvest, drawing families together to mark the changing of the seasons and the cycle of the crops. While the larger professional sports leagues remain a distant spectacle to be followed on screens, the community finds its own excitement in high school athletics, which serve as a primary focus for weekend gatherings and civic pride. The landscape is marked by the presence of Brentwood Park, a primary destination for those seeking a moment of stillness or recreation without leaving the immediate vicinity. Famous individuals have occasionally passed through or resided here, drawn by the same atmospheric quality of light that gives the afternoons in the valley their particular, heavy-lidded charm.

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.
