Which of the following is a benefit of proper drainage systems?

Proper drainage systems are designed to effectively manage and direct surface water away from structures and areas where it could cause issues such as flooding and standing water. The primary benefit is the significant reduction of standing water and risks associated with flooding. When draining is optimized, water is channeled appropriately, minimizing the chances of water pooling in undesirable locations, which can lead to property damage, harmful mold growth, and soil erosion. This proper management of water helps maintain the integrity and safety of the surrounding areas.

While proper drainage can sometimes contribute to aesthetic improvements and may potentially lower certain costs over time by preventing damage, the most direct and vital benefit lies in the prevention of water accumulation, thus safeguarding property and landscapes from flooding risks and associated problems.
