Why this matters
Site Conditions
Imagine a plot looks perfect during a viewing, but you do not yet know what the landscape can do—or what protections apply to it. Wildfire, flooding, protected areas and other site conditions can affect safety, design, access, cost and the checks needed next. A clean-looking online map does not prove that every relevant risk is absent. Use these guides to recognise the warning signs, find the current evidence and know when specialist or official confirmation matters. The simple rule: What you can see on a visit is only part of the site; check the current mapped and physical conditions together.
What this page helps you do

Map the condition, then ask what it changes
A hazard or protected-area layer is a signal to investigate—not a verdict.
Wildfire, flood and protected-area information has different dates, scales, coverage and legal effects. Use the full parcel and intervention geometry, keep the official source visible and take the resulting question to the authority responsible for it.Three questions turn an overlay into a useful check
What exactly overlaps, and from which dated source?
Record the layer, version, geometry and whether the parcel, building area, access or services intersect it. A coloured pixel without provenance is not a reproducible result.
Which part of the proposal could be affected?
Construction, access, vegetation work, drainage and operation may raise different questions. Do not reduce a whole-parcel condition to the selected point.
Who confirms the consequence and current requirements?
Municipality, civil protection, APA, ICNF or another sector authority may answer different parts. Ask each body only what falls within its remit.
