Los Angeles 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 LA County address, from the beach cities to the foothills, in about a minute.
What Lekua resolves in Los Angeles County
Every layer below is pulled live from LA’s own GIS and authoritative state sources the moment you enter an address — no manual tracing, no generic insets, every source cited.
Assessor parcel boundary with AIN, situs address, lot area, and use type — from the county’s own parcel service.
Fine 1–2 ft contours generated on-demand from the 1-meter USGS 3DEP elevation model, with LA County’s LARIAC 2-ft vector contours as the live fallback — hillside-grade relief either way.
LARIAC 2023 countywide building outlines (with measured heights), falling back to the 2020 flight and gap-filled with national data for anything the county layer misses.
Parcel jurisdiction resolved across the county’s 88 cities and unincorporated communities. Setback tables are encoded and code-cited for the City of Los Angeles (LAMC §12.07–12.08) and unincorporated county land (Title 22); rings draw once a table passes independent review, and prevailing-setback and hillside rules ride as citations rather than guessed lines.
CAL FIRE FHSZ severity (2024–25 remap) with Zone 0 / 1 / 2 defensible-space perimeters drawn around structures — pointed where it counts in the Santa Monica Mountains, the foothills, and the canyon WUI.
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 agency — LADWP and Long Beach run their own enhanced turf programs on top of MWD’s SoCal Water$mart.
Built for LA’s canyon and foothill fire interface
From the Santa Monica Mountains to the San Gabriel foothills, LA County’s hillside neighborhoods sit 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 — so a fire-wise, code-aware design comes out of 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.
Zoning setbacks, by jurisdiction
Setbacks in LAare set per town, not countywide. Lekua resolves the parcel’s jurisdiction and zone code and encodes each jurisdiction’s adopted setback table, citation and all. Setback rings are drawn only after a table passes independent panel review — until then the export carries the code-cited values with an explicit “unverified” advisory instead of lines we can’t stand behind.
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: Metropolitan Water District (SoCal Water$mart) · LADWP turf-replacement program · Long Beach Lawn-to-Garden.
Los Angeles County base map FAQ
Can I get a CAD base map for an LA County parcel?
Yes. Enter any Los Angeles County address and export a layered DXF (AutoCAD-compatible) with property lines, LARIAC building footprints, on-demand 1–2 ft contours, spot elevations, and the zoning determination with code-cited setbacks — plus a designed PDF site report for the client.
What contour interval is available in LA County?
Lekua generates fine 1–2 ft contours on-demand from the 1-meter USGS 3DEP elevation model, with LA County’s LARIAC 2-ft vector contours as a live fallback — far finer than the 10-ft national data most tools show, which matters on hillside lots for grading and drainage.
Does it include zoning setbacks for LA cities?
The parcel’s jurisdiction is resolved across all 88 incorporated cities and unincorporated communities, and setback tables are encoded with citations for the City of Los Angeles (LAMC §12.07–12.08) and unincorporated county land (Title 22). Setback rings are drawn only after a table passes independent panel review; until then the export carries the code-cited values with an explicit “unverified” advisory and always labels the zone determination honestly.
How does it handle defensible space and fire-safe planting?
Lekua draws CAL FIRE Zone 0 / 1 / 2 defensible-space perimeters around the structures and tags every recommended native with the zones it’s suited to — using flammability data from Las Pilitas burn-time research and UCANR / CAL FIRE-aligned fire-safe lists.
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.
