Water Authority — Topsoil Placement (14345)
Define the finished purpose, reference levels, underlying material condition and the evidence required by the receiving operation. Geometry alone does not establish structural or agronomic performance.
This reference assembles relevant extracts from the guide library. It is general project planning, not a local project report, verified specification or translated technical publication.
Water Ponding
Ponding is a symptom, not a design instruction. Filling the wet patch can push water into another area if the outlet or surrounding grade remains wrong.
Before moving material
Record pond extent, duration and outlet condition.
Receiving operation and checks
Correct the confirmed issue and observe the result after suitable rainfall or irrigation. Check water movement beyond the repaired patch.
Persistent wetness may require soil or drainage investigation beyond grading.

Uneven topsoil can mean different layer depths even when the upper surface looks smooth. That matters when the next use requires a consistent growing layer.
Before moving material
Check topsoil depth separately from overall surface elevation.
Receiving operation and checks
Complete cultivation, planting or turf establishment. Measure depth in both former high and low areas.
Do not use topsoil as a remedy for an uncorrected structural formation.
Read the complete Uneven Topsoil guideTopsoil Grading
Topsoil grading controls the growing medium over an underlying formation. It should not be used to conceal a formation error that demands structural correction.
Before moving material
Accept the underlying level and identify suitable topsoil.
Receiving operation and checks
Complete seedbed, planting or turf preparation. Measure growing-layer depth at representative high and low locations.
Topsoil is generally a different material role from structural fill.
