Term Definition
303(d)-listed waterbody Under Section 303(d) of the Clean Water Act, every 4 years, states are required to develop a list of waterbodies that do not meet water quality standards, and to establish priorities and develop action plans, called Total Maximum Daily Loads (TMDLs), to improve water quality.
ASBS Areas of Special Biological Significance, also called California’s State Water Quality Protection Areas, are marine or estuarine areas designated to protect marine species or biological communities from an undesirable alteration in natural water quality.
CAFO Contained Animal Feeding Operations are large livestock (i.e.,cattle, chickens, turkeys, or hogs) production facilities that are considered a point source pollution. 
CCA # Unique identifying number for each Critical Coastal Area
Channelization The process of changing and straightening the natural path of a waterway.
Hydromodification Alteration of the hydrologic characteristics of coastal and non-coastal waters, which in turn could cause degradation of water resources. In the case of a stream channel, this is the process whereby a stream bank is eroded by flowing water. This typically results in the suspension of sediments in the water course.
MMA A Marine Managed Area is a marine or estuarine area along the California coast designated by the state to protect, conserve, or otherwise manage a variety of resources (e.g., living marine resources and their habitats, scenic views, water quality, recreational values, and cultural or geological resources) and their uses.
MPA A Marine Protected Area is a marine or estuarine area seaward of the high tide line or the mouth of a coastal river, together with its overlying water and associated flora and fauna, that has been designated by the state to protect or conserve marine life and habitat.
OWTS Onsite Watewater Treatment Systems are systems relying on natural processes and/or mechanical components that are used to collect, treat, and disperse or discharge wastewater from single dwellings or buildings.
Riparian areas An area of streamside vegetation including the stream bank and adjoining floodplain, which is distinguishable from upland areas in terms of vegetation, soils, and topography.
SF Bay CCAs in the San Francisco Bay Region inside of the Bay. 
SF Ocean CCAs in the San Francisco Bay Region outsice of the Bay (Marin and San Mateo Counties) 
TMDL The Total Maximum Daily Load is a calculation of the maximum amount of a pollutant that a waterbody can receive and still meet water quality standards, and an allocation of that amount to the pollutant's sources.
Vegetated Treatment Systems Engineered systems designed to simulate natural wetlands to exploit the water purification functional value for human use and benefits.
