Critical Infrastructure List Supporting
Summaries
9/30/2022
Air Release Station
Air release valves are appurtenances located on water transmission mains throughout the City.
A portion of the piping of an air release valve is above ground. There are over 650 air release valves located throughout Sacramento within City right-of-way.
These facilities are located within City
ROW or easements.
Basins
Basins constitute a facility for producing, storing, diverting, conserving, treating, or conveying water. Drainage flood control and water quality detention basins are a part of the City’s drainage system and prevent flooding and protect the City’s local creeks and rivers as required by the City’s State NPDES Permit.
Drainage collection currently maintains
164 basins throughout the City as part of
the critical infrastructure conveyance
system.
Booster Station
One potable water booster pump station exists within the City of Sacramento at 4299 Astoria Street. It maintains the pressure in a historically lower pressure area of the city.
The facility and parcel are critical.
Combined Sewer System Vaults
There are four stormwater vaults within the City of Sacramento Combined Sewer System, designed to provide additional storage capacity during large rain events. All four vaults are in high profile areas and located underground. If these vaults not accessible, become damaged or unusable, the impact will create safety and public health hazards throughout the system. There will be a risk of property damage to the residences and City above and adjacent infrastructure as well. If the associated pumps for the vaults are not accessible or damaged it will delay vault maintenance and preparation for future storm events. Everything listed above will affect the decisions that are made by City Staff on operations of the Combined Sewer System and increase potential outflows to City streets and overflows to the Sacramento River.
These facilities can be on a parcel or part
of another critical facility.
Drainage Canals
Drainage canals and channels are critical conveyance elements that deliver rainfall runoff from urban areas to receiving waterways. Channels can have multiple pump stations pumping flows into them. It's critical to maintain channel side slope integrity to prevent erosive action. Failure in channels/canals can lead to significant flooding for large areas of the city. these facilities are located over long
stretches and pass through multiple
neighborhoods.
Fire Stations
Fire Stations provide critical services for fire and emergency medical responses in our city and community. If there is a disruption of service, due to the fire department’s inability to access or leave from the location, or damage to the station, the city and community would suffer due to delays in emergency response.
These facilities are typically on a parcel
associated with a critical facility.
Flood Protection Barrier – Floodgates,
Sluice gates, Flap gates
A flood protection barrier is a specific type of floodgate that is designed to prevent water from entering through a primary or secondary levee. Floodgates are installed or closed to block water from entering the city. Sluice gates are closed to prevent water, stormwater, or wastewater from entering or backing up into the city. Flap gates prevent water from entering the city through pipes and causing flooding.
There are several sites across the city;
many have components that are stored
elsewwhere and deployed as needed to
safeguard the city.
Gathering Areas
Gathering areas across the City often consolidate the largest number of persons in a confined area, which have historically been ideal targets for extremist and terror attacks. Gathering areas are also often ideal locations to conduct mass care and shelter for evacuees given the range of onsite support to host large groups of people.
Typically just the facility is critical and the
parcel consists of parking lots and/or
additional business enterprise.
Government Operations
This includes key locations where governance is conducted, and support to the community is administrered from. This oft includes administration buildings where plans, procedures, and fees may be processed; additionally, this can include locations that host community services, such as: sheltering, childcare, youth programs, etc.
These facilities can be on a parcel or part
of another critical facility.
Landfill Gas Extraction System
The City owns and operates an extensive landfill gas extraction system, including two flare stations on the east and west side of Sutter’s Landing Regional Park. This system prevents the release of landfill gas that would be harmful to the environment and nearby communities.
Operation of this infrastructure is vital to the safety of the surrounding homes and businesses, who would be potentially exposed to risk should this equipment fail.
These facilities are typically on a parcel
associated with a critical facility.
Levees
Levees protect the Sacramento area from flooding due to high river or creek/stream levels caused by rainfall events that produce high volumes of runoff. Without the ability to maintain these facilities the flood risk to Sacramento residents is increased.
Most levees around Sacramento have
flood control easements along
rivers/creeks/streams. Levees are not
typically on a single parcel or within the
ri
ght-of-way.
2022 City of Sacramento Critical Infrastructure List
PG&E Gas line infrastructure
PG&E provides gas service to DOU Water, Wastewater, and Drainage facilities. Loss of PG&E service may result in potential flooding, sanitary sewer overflows, and no water production and treatment.
These facilities are typically on a parcel
associated with a critical facility.
Police Stations and Facilities
Police Stations and Facilities are critical to the safety of the community as they house dispatch communication, peace officers, their vehicles, and equipment. If those facilities are damaged or prevented from being used, it would negative impact the Police Departments ability to provide community services, thereby threatening the safety of our City.
These facilities are typically on a parcel
associated with a critical facility.
Potable Wells
The City currently is permitted to operate 28 groundwater wells. Twenty-six (26) are located in the northern portion of the City, north of the American River and two are located south of the American River. Two additional wells are currently under construction south of the American River. Groundwater wells provides 20% of the annual potable water supply for the City of Sacramento and wholesale customers.
Potable wells are facilities and are located
at 28 city owned parcels throughout
Sacramento.
Rivers/Creeks
Rivers and Creeks are important elements of the City's drainage system as they pass storm flows from distant areas through our city as well as collect drainage from city neighborhoods.
The City is protected from high flows in rivers and streams by the levee systems that border these water coarses. Maintaining levees per guidelines is mandated by regulating State and Federal agencies. Access for monitoring during high flows is critical. Failure of this asset can lead to catastrophic flooding in our City.
Rivers and Creeks traverse through or are
adjacent to much of our City.
SMUD Power Infrastructure
SMUD provides electrical service to DOU Water, Wastewater, and Drainage facilities. Loss of SMUD service may result in potential flooding, sanitary sewer overflows, and no water production and treatment.
These facilities are typically on a parcel
associated with a critical facility.
Storage Facility
The City currently has 16 water storage facilities: 11 distributed storage tanks located throughout the City, and five clear wells located at the water treatment plants (three at the SRWTP and two at the FWTP). The storage facilities, or reservoirs, store water and pump water into the transmission main system for distribution into neighborhoods, mostly during periods of high demands.
The storage facilities, or reservoirs, are
facilities and are located at 14 different
sites.
Sump Station
Wastewater and drainage is collected in underground pipes and flows to a collection point at a lower elevation which is a sump station. At the sump station wastewater is pumped to a force main pipe that conveys wastewater to a treatment plant for treatment. At the drainage sump, the water is pumped to a force main pipe that conveys the water to creeks and rivers. These facilities are essential to prevent flooding during rain events and to reduce sewer outflows.
Sump are facilities and are located on city
owned parcels.
Treatment Plant
The City treats surface water diverted from the Sacramento and American Rivers through the Sacramento River Water Treatment Plant and the E.A. Fairbairn Water Treatment Plant. These two water treatment plants provides 80% of the annual potable water supply for the City of Sacramento and wholesale customers.
The WTPs are facilities and are located at
301 Water Street and 7501 College Town
Drive.
Turnout
The City maintains seven metered wholesale/wheeling connections to other adjacent agencies and 21 additional emergency interties. The turnouts are located throughout Sacramento within City right-of-way. The turnouts/interties are used for emergency water supply.
These facilities are located within City
ROW or easements.
