San Bernardino County base maps & site data for designers
The existing-conditions base map and pre-design site analysis that normally takes a half-day of GIS hunting and a site visit — for any San Bernardino address, from Redlands to Lake Arrowhead, in about a minute.
What Lekua resolves in San Bernardino County
Every layer below is pulled live from San Bernardino’s own GIS and authoritative state sources the moment you enter an address — no manual tracing, no generic insets, every source cited.
County assessor parcel boundary with APN, address, and lot area, with the statewide CA parcel layer as fallback.
Fine 1–2 ft contours generated on-demand from the 1-meter USGS 3DEP elevation model — far finer than the 10-ft national data most tools show.
County-hosted building footprints, gap-filled with FEMA national structures for anything the county layer misses.
CAL FIRE FHSZ severity (2024–25 remap) with Zone 0 / 1 / 2 defensible-space perimeters drawn around structures — pointed where it counts: the mountain communities — Arrowhead, Big Bear, the front-range foothills —.
USDA SSURGO soil profile, historical rainfall, and modeled seasonal sun-hour heat maps for the parcel.
California natives matched to the site’s soil and microclimate, plus lawn-replacement rebate estimates from the serving provider — San Bernardino Municipal Water and local programs.
Tuned for San Bernardino’s fire interface
The mountain communities — Arrowhead, Big Bear, the front-range foothills — sits in mapped fire-hazard severity zones, and defensible-space planting rules now shape those projects. Lekua draws the CAL FIRE Zone 0 / 1 / 2 perimeters on the plan and filters the plant palette to what each zone allows — fire-wise from the first pass.
- Zone 0 (0–5 ft ember-resistant), Zone 1 (5–30 ft), and Zone 2 (30–100 ft) perimeters drawn around the structures.
- Every recommended plant carries a defensible-space zone rating, so you place the right species in the right zone.
- Flammability ratings draw on Las Pilitas burn-time research and UCANR / CAL FIRE-aligned fire-safe lists.
A native palette, enriched beyond the plant list
Start from the Calscape native plant database — then get the research-backed traits Calscape alone doesn’t put at your fingertips, matched to the parcel’s exact soil, sun, rainfall, and microclimate. Hand a client a list that’s code-compliant, climate-appropriate, and built to perform.
Flammability and defensible-space zone suitability from Las Pilitas burn-time research and UCANR / CAL FIRE-aligned fire-safe lists — not just a name on a list.
Slow / moderate / fast growth plus mature height and spread, so spacing and time-to-fill are realistic from day one.
Calscape cultivation and longevity guidance, so the palette reads for how it performs over 10–20 years, not just at install.
WUCOLS-aligned water-use ratings (for the MWELO budget) and pollinator / bird support scores on every species.
Plant data: Calscape / CNPS, enriched with Las Pilitas burn-time research, UCANR & CAL FIRE-aligned fire-safe lists, and WUCOLS water-use ratings.
Water districts & rebates
Lawn-replacement rebate estimates are matched to the serving district: San Bernardino Municipal Water · Cucamonga Valley Water District · Inland Empire Utilities Agency.
San Bernardino County base map FAQ
Can I get a CAD base map for a San Bernardino County parcel?
Yes. Enter any San Bernardino address and export a layered DXF (AutoCAD-compatible) with parcel lines, building footprints, on-demand 1–2 ft contours, and spot elevations — plus a designed PDF site report for the client.
What contour interval is available in San Bernardino County?
Lekua generates fine 1–2 ft contours on-demand from the 1-meter USGS 3DEP elevation model — far finer than the 10-ft national fallback most tools show, which matters wherever grading and drainage drive the design.
Does it include zoning setbacks for San Bernardino County?
Not yet — setback tables for Redlands, Rancho Cucamonga, and the county are not yet encoded, and the export never guesses: where a setback isn’t verified it says so plainly instead of drawing lines. Encoded tables follow the same review-gated process as other counties.
How does it handle defensible space and fire-safe planting?
Lekua checks the parcel against current CAL FIRE FHSZ maps, draws Zone 0 / 1 / 2 defensible-space perimeters around the structures where designated, and tags every recommended native with the zones it’s suited to.
Is the data current and reliable enough for submittals?
Layers are pulled live from county GIS, USGS, and CAL FIRE at export time, and any encoded setback table cites its source with a date. Everything is labeled “for planning reference — not for construction.” Verify against the current code and a stamped survey before submittal.
