What is the finished elevation of lot no. 409?

The finished elevation of lot no. 409 is correctly identified as 152 feet 4 inches. This measurement is typically determined by a combination of site surveys, design specifications, and engineering calculations that consider factors such as drainage, grading requirements, and local zoning laws.

In civil engineering and land development projects, achieving the correct finished elevation is crucial for ensuring proper site drainage, structural stability, and compliance with regulations. The selected value reflects a precise readout, likely based on architectural or engineering plans. Each of the other elevations provided may be plausible in different contexts or lots, but they do not align with the identified finished elevation for this specific lot, which has been established through the aforementioned processes.
