A more thorough explanation:

AD REPARATIONEM ET SUSTENTATIONEM

Ad reparationem et sustentationem (pronounced ad rep-uh-ray-shun-um et suh-sten-tay-shun-um) is a Latin legal term that means "for repairing and keeping in suitable condition."

• A landlord may use a tenant's security deposit ad reparationem et sustentationem of the rental property after the tenant moves out.
• A city may allocate funds ad reparationem et sustentationem of its public parks and playgrounds.

These examples illustrate how the term ad reparationem et sustentationem is used in legal contexts to refer to the maintenance and upkeep of property. In the first example, the landlord is allowed to use the tenant's security deposit to make necessary repairs and keep the rental property in good condition. In the second example, the city is responsible for allocating funds to maintain its public parks and playgrounds, ensuring that they are safe and enjoyable for the community to use.
