The Half Moon Bay Landfill is located in a coastal region of California, which presents specific environmental considerations for solid waste management. Proximity to the Pacific Ocean and local groundwater aquifers necessitates robust leachate management systems to prevent contamination.

Landfill gas collection and methane leakage are key concerns, as methane is a potent greenhouse gas. Community proximity and traffic from waste hauling also require careful planning to minimize odors and noise.
