A parking lot wears out. The ground under it does not. That is the whole reason the two are separate accounts.
Paving, fencing, outdoor lighting, landscaping with a finite life, driveways, and private roads all go to land improvements. Each is depreciated over its own useful life, typically far shorter than a building's. Grading and clearing that permanently prepare the site go to land and are never depreciated.
The test is whether the expenditure has a life of its own. Filling and levelling a lot changes the ground permanently. Asphalt creates a separate asset that will require replacement. The first cost is land, and the second is an improvement. One contractor may perform both kinds of work.
Getting this wrong is quiet and expensive. Improvements buried in land never enter a depreciation schedule, so expense remains understated until correction. The asset register can then retain an old paved lot after its replacement.
Connect classification with later allocation
ASC 360-10-30-1 connects initial cost with intended location and condition. Paragraph 35-4 requires systematic and rational allocation over expected useful life. Together, these ideas explain why a limited-life site asset is recorded separately from the ground.
Retain the work order, asset identity, readiness date, cost, life, salvage estimate, and depreciation method. Reconcile mixed contractor invoices to land, improvements, building, and period cost. The Cedar property example shows that control before independent practice.
After replacement or disposal, remove the supported original improvement and its accumulated depreciation. Do not leave both the old and new assets in the register merely because the ground remains in use.
Put the concept to work
Understand this concept
- Explain what makes an expenditure a land improvement rather than part of land, and why the distinction changes whether it is depreciated.
Apply this concept
- Separate land improvements from land in a set of property costs, and compute depreciation on the improvements over their own useful lives.
