High Ground levee

High Ground levee

This so-called “high ground” levee is proposed to be built around Stewart Tract. Construction would take place inside of the existing levee, which would remain. This diagram gives a sense of how the levee and adjacent landscape might work, and describes some of the benefits of the new inner levee.

Empire Tract drainage pumps

Empire Tract drainage pumps

The size of this pumping station is fairly typical. Pumps like this allow Delta farmers to precisely control the groundwater level in their fields. Without constant pumping, Delta fields would fill with water from the surrounding, higher rivers and sloughs. Like levee maintence, much of which is done by Delta landowners, the expense of pumping affects Delta farmers’ competitiveness in the global agricultural products market.

Setback levee diagram

Diagram shows the basic features of a setback levee and compares it to a conventional levee.

Borrow pit, eastern edge of Delta

Borrow pit, eastern edge of Delta

This is one of several “borrow pits” that were created during the construction of Interstate 5. Many have developed substantial riparian habitats.

Siphon spring diagram

Siphon spring diagram

Conceptual diagram of a peripheral canal siphon spring facility. Siphon springs would occur at the intersections of the proposed canal and existing Delta waterways. Siphon springs would be in part infrastructure, and part an occasion to create a new Delta recreational space.

The diagram shows a siphon passing under an existing Delta waterway, and two head-driven artificial artesian “springs” that would inject Sacramento River water into intersecting waterways.

Possible peripheral canal route?

Possible peripheral canal route?

Purely a speculative diagram, this route would take economic advantage of a number of “borrow pits,” so-called because they were created to provide fill for the construction of I-5. The pits are similar in dimension to the proposed “isolated conveyance facility.” Most are now riparian habitats, and some are protected wildlife preserves. The diagram also shows how the siphon infrastructure at intersecting rivers and sloughs could be designed to “freshen” the Delta’s waterways, improving Delta water quality and ecosystem health.

Large Owner Axis Trail

Large Owner Axis Trail

The Large Owner Axis Trail is correlated to the 2009 Peripheral Canal proposal’s “through-Delta component. The trail extends from the proposed Sacramento River diversion facility in the North Delta to the State and Federal Water Project pumps in the southwest Delta. From north to south, the elements of the trail system include: Stone Lakes NWR Trail, Snodgrass Slough Lodgecamp, Pear and Vine Trail, Delta Cross Channel Lodgecamp, Historic Settlements Trail, Staten Island Lodgecamp, Birdwatchers’ and Sportsmens’ Trail, Bouldin Island Lodgecamp, Habitat Mitigation Trail, Connection Slough Anglers’ Dam, Bacon Island Lodgecamp, Railroad Cut Anglers’ Dam, Channel Islands Trail, Double Canal Anglers’ Dam, Victoria and North Canals Estate Trail, and Clifton Court Forebay Lodgecamp

Isolated facility - eastern alignment alternative

Isolated facility - eastern alignment alternative

The Eastern Alignment Isolated Facility is the latest preferred alternative of the planners of the ongoing crisis in California’s contentious debate over Delta water export.

Two components comprise the facility—The Eastern Alignment Isolated Conveyance Component, and Through-Delta improvements. The proposed EAIC would have 1/ a 41-mile canal skirting the eastern edge of the Delta; 2/ an intake facility near hood that would divert up to 15,000 cfs out of the Sacramento River before entering the Delta; 3/ 8 siphons over rivers and sloughs; 4/ 3 culverts under sloughs; 5/ 18 bridges over state highways and roads; 6/ 2 rail bridges

The through-Delta improvements would include: 1/ 75 miles of retrofitted setback levees; 2/ 60 miles dredged rivers and sloughs; 3/ barriers at Old River, Connection Slough and Woodward Canal; 4/ a siphon at old river to direct water to clifton court forebay.

Water Project Aqueduct

Water Project Aqueduct

State and federal aqueducts supply northern California water to the southern half of the state. This supply will increase as a percentage of total supply due to decrease export from the Colorado River.

Temporary barrier locations

Temporary barrier locations

South delta temporary barriers resolve conflicts between water quality and environmental advocates. Barriers similar to this one are a key component of the Peripheral Canal proposal, and are the sites of future speculative work by the DNP design team.

South Delta section of Levee Urbanism

South Delta section of Levee Urbanism

This cross section diagram describes the various components of Levee Urbanism in the South Delta. Channel making would increase water carrying capacity and water frontage for property development, a potential source of significant value for local landowners, and create habitat that would be managed by property owners.
