Yolo County base maps & site data for designers
The existing-conditions base map and pre-design site analysis that normally takes a half-day across county GIS portals and hand-tracing into CAD — for any Yolo address, from Davis to Winters, in about a minute.
What Lekua resolves in Yolo County
Every layer below is pulled at export time from county, state and national GIS sources the moment you enter an address — no manual tracing, no generic insets, and the sheet cites which source drew each layer.
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 for anything the county layer misses with national outlines: Overture Maps’ mixed mapped and machine-learned outlines where a county cut is imported, otherwise FEMA USA Structures with Microsoft machine-learned outlines where FEMA has none.
CAL FIRE FHSZ severity checked for the parcel, with defensible-space perimeters drawn where the parcel sits in a designated zone.
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 the serving water supplier’s lawn-replacement rebate, shown only while it was verified on the supplier’s own page within 60 days.
Fire risk, checked rather than assumed
Most Yolo parcels sit outside mapped fire-hazard severity zones — but the western hills toward Lake Berryessa carry designated zones. Lekua checks the parcel against the current CAL FIRE 2024–25 maps rather than assuming either way, and draws defensible-space perimeters only where they apply.
- Parcel-level FHSZ check against the current CAL FIRE 2024–25 maps.
- Zone 0 / 1 / 2 perimeters drawn only where the parcel is in a designated zone.
- Every recommended plant still carries its flammability data.
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 mapped soil, sun, rainfall, and microclimate. Hand a client a list checked against the code, 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.

Yolo County base map FAQ
Can I get a CAD base map for a Yolo County parcel?
Yes. Enter any Yolo 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 Yolo 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 Yolo County?
Only where a table has been encoded and reviewed — the cards above list each one and say whether its envelope is drawn or only cited. Tables for Davis, Woodland and most of the county’s cities are not yet encoded, and the export never guesses: where a setback isn’t verified it says so plainly instead of drawing lines.
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.
