Streams, water bodies and flood risk on land

A stream, canal, pond or seasonal watercourse near a parcel is not automatically good or bad. Water can support agriculture, views and microclimate, while also introducing flood, setback and soil risks.

A dry-looking channel in a photo may carry water during heavy rainfall. The parcel should therefore be read with topography, flow direction, flood records and water-protection buffers, not only with current imagery.

Data that changes the decision

• Horizontal distance to the stream and the parcel's elevation relationship with it.
• Overlap with flood, landslide or ground-risk layers.
• Setback rules and whether an authority opinion is required.
• The difference between seasonal drainage and permanent water presence.

Boundary statement: This article is not an engineering report, authority opinion, zoning certificate or soil study; water and flood conclusions must be verified through competent official records.

Parselo shows the parcel boundary together with water and risk layers, marks intersections in the report and uses video to explain what proximity to water may mean in plain language.
