Water Quality

“Minor: Minor water quality impacts would include temporary, localized impacts that may or may not be detectable, would not have long-lasting effects on water quality, and would be within historical or desired water quality conditions.

Moderate: Moderate impacts are short-term and long-term detectable impacts that would change the chemical, physical, or biological integrity of water quality to the degree that the action would alter the historical baseline or desired water quality conditions of Drakes Estero.

Major: Major impacts are short-term and long-term detectable impacts that would change the chemical, physical, or biological integrity of waters of Drakes Estero to the degree that the action would alter the historical baseline or desired water quality conditions.”

Soundscapes

“Minor: Human-caused noise would be at a level that causes vocal communication to be difficult between people separated by more than 32 feet, and the natural soundscape is interfered with less than 5 percent of the time.

Moderate: Human-caused noise would be at a level that causes vocal communication to be difficult between people separated by 32 to 16 feet, and the natural soundscape is interfered with 5 to 10 percent of the time.

Major: Human-caused noise would be at a level that causes vocal communication to be difficult between people separated by less than 16 feet, and the natural soundscape is interfered with more than 10 percent of the time.”

Socioeconomics

“Minor: Impacts may be detectable but would not affect the overall regional economy or the statewide production of shellfish.

Moderate: Impacts would be clearly detectable but would not considerably affect the regional economy or the statewide production of shellfish.

Major: Impacts would be highly noticeable and would substantially influence the regional economy or the statewide production of shellfish.”
