This schedule lists different types of land improvements that can be depreciated for tax purposes. These are structures or facilities that are built on or attached to land and can lose value over time.
The list includes things you might see at an airport, like runways, or in a city, like roads and bridges. It also includes structures used for water management such as dams, reservoirs, and wells. Other items on the list are fences, chimneys, tunnels, and swimming pools.
Some less common items mentioned are hardstanding (which is a paved area for parking or storage), spillways (structures that allow water to flow from dams safely), and purpose-built surfaces for outdoor sports facilities. The list also includes wharves, which are structures built along the shore where ships can dock.
