  • · Wide range — county $/sqft mixes condos, single-family and luxury; the low–high band matters more than the point.
  • · County-level comp model — no adjustment for condition, view, or remodel. An estimate, not an appraisal.

Build constraint
Favorable

No significant build constraints in the data available for this parcel.

Partial coverage — based on the soil/geohazard layers present for this parcel; the read sharpens as those backfill.

Climate profile
Long-run climate normals at the parcel centroid, averaged over 20142023. Drives growing season & water for ranch/ag use, plus snow load for buildability.

Source: Open-Meteo Historical Weather archive (ERA5 reanalysis), 20142023 daily normals. Frost-free days count days whose overnight low stayed above 32°F. The snow-load band is a buyer-facing heuristic from annual snowfall, not an engineered ground-snow-load design value — confirm with the local building department before relying on it.

Water security
Decreed surface-water rights & seniority synthesized into one prior-appropriation read — the water question a ranch or land buyer leads with.
Water security
Vulnerable

No decreed water rights on record — on-site water would rely on a well permit or hauled water. A real constraint in a drought- or fire-exposed area.

Water rights

No water rights linked to this parcel. We spatially join CO Division of Water Resources records within 200m of the parcel centroid. Most non-agricultural mountain parcels have none on file.

Water well
A permitted water well falls within this parcel (primarily domestic). A permitted well is real, recorded water access from the CO Division of Water Resources — and on unbuilt rural land it is often the gating utility for buildability.

Distance is measured to the nearest edge of each unit's bounding box (a fast approximation, not precise polygon containment). “Inside unit boundary” means the parcel centroid sits within the unit's bbox; verify against the unit's precise boundary before acting.
