What is the minimum elevation for the top of the foundation relative to the street gutter?

The minimum elevation for the top of the foundation relative to the street gutter is typically established to ensure adequate drainage and to prevent water infiltration into the structure. A foundation that is at least 12 inches above the street gutter helps ensure that surface water flows away from the house, reducing the risk of flooding in basements or crawlspaces, and protecting the integrity of the building materials from water damage.

Maintaining this elevation standard is crucial for long-term durability and can also be a requirement stipulated by local building codes. It reflects the best practices in residential construction to mitigate potential issues related to water accumulation around the foundation, which can lead to mold growth, structural damage, or systems failure (like electrical issues due to moisture).

The other listed elevations do not provide the same level of protection from surface water and may not meet local building regulations. Lower elevations might increase the risk of foundation problems due to poor drainage, making the 12-inch elevation a sensible choice for safeguarding residential properties against water-related issues.
