Know the ground before the site visit.

Parcel

Outline, tax lot, assessor details, land use, the state zoning class and the city's own zone code where it publishes one, and the elevation and slope at the point. Outlines in all 36 counties; in Union County only within the Upper Grande Ronde basin.

Soils

NRCS drainage class, hydrologic group, water table and septic rating. The septic rating is withheld when it would describe only a minority of the ground.

Utilities

The nearest public sewer, storm and water main, from nine Oregon utilities. Approximate, not a locate: call 811 and verify with the utility.

Power

High-voltage lines within 200 ft, with owner and voltage. Approximate alignment: verify against title and survey.

Survey

Township, range and section, and any Donation Land Claim, from BLM. Reference only, not a survey.

Highway

A state highway within 300 ft, with its milepoints and distance from the centerline, and ODOT's right-of-way maps for that stretch. ODOT publishes no right-of-way width, so none is shown.

Water

OWRD water rights, wells and groundwater restricted areas near the lot.

Five bands from under 5% to over 40%, with the acres in each, measured from DOGAMI lidar. Hillside checks flag steep ground, mapped landslides, soils and flood. A check whose source did not answer reads Not checked, never Clear.

Pick the parcel or draw a box, choose an interval from 0.5 to 40 ft, and download a DXF in Oregon State Plane, or KML or KMZ.

Map layersOver twenty on the map, each with its own opacity: zoning, flood, wetlands, streams, landslides, slope, hillshade, contours, soils, tax lots, the survey grid, water rights and wells, state highways, power lines and utility mains.

1. All data is screening data from public sources. It does not replace a field survey, a title report or a geotechnical report.
2. Utility mains are approximate and are not a locate. Call 811 and verify with the utility. They appear in downloads only where the utility's terms allow.
3. Parcel outlines come from county assessors and regional governments in all 36 counties. Union County's cover only the Upper Grande Ronde basin, and Grant County's date from 2016.
4. Slope and hillside checks never say buildable. A check whose source did not answer reads Not checked, never Clear.
5. Cut and fill are estimated from lidar ground: a screening figure, not a grading plan.
6. Setbacks are as you enter them, or as you confirm them from the code. Neither is a city review.
7. Site concepts are early layouts to start a conversation, not a design. The AI reads the code and suggests arrangements; ordinary code draws each layout and runs every check.
8. A standard read from the code is used only after you confirm it. One whose sentence cannot be found on its page is marked so.
9. Concept heights are approximate, at 11 ft a story. Where the code gives no stall or aisle size, 9 × 18 ft stalls and a 24 ft aisle are assumed and named on the concept.
10. Concepts work on one piece of land. On an irregular lot, buildings and parking go in its largest rectangle inside the setbacks, and the concept says how much that leaves out.
11. Scanned PDFs cannot be read. We keep the code's text, not the PDF.
12. Township, range, section and Donation Land Claims are BLM reference data, not a survey.
13. Highway distance is measured from the centerline. ODOT publishes no right-of-way width, so none is shown.
14. Power lines are an approximate alignment from HIFLD. Verify against title and survey.
15. Nothing found means only that the source reported nothing.

$99 covers one user and $199 covers two, for all of Oregon. Once you subscribe, add seats for your team at $49 a month or $490 a year each, up to 20. A seat added part-way through a billing period is charged for the days left, that day. Moving up to Pro starts once the payment goes through, and you pay only the difference for the days left in your period. Moving down to Standard happens at your next renewal, and you keep Pro until then. After the free trial, the plan renews automatically, at the price of your plan and seats, until you cancel. Cancel any time from your billing page, and you keep access to the end of the period you have paid for. No refunds.
