River Islands development plan

River Islands development plan

Master plan of River Islands. A new super levee surrounds a set of more-or-less conventional suburban housing neighborhoods.

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.

Industrial-scale winery near Interstate 5, in the Delta’s Secondary Zone, and in the Borrow Pit Exchange Authority. The large-scale, often industrial or infrastructural, elements that are beginning to dominate this area need to be organized in more effective, sustainable ways.

South Delta Exchange Authority

The South Delta Exchange Authority trades development, water quality, agricultural, environmental, and tourism interests. See Levee Urbanism for a description of the SDEA at an architectural scale.

River Islands development plan

River Islands development plan

River Islands is a development proposed for Stewart Tract in the southeast Delta. It would build a new community protected by a “super levee.”  This new levee is seen by adjacent landowners as a breach in the long-standing agreement to build levees to the same height, thereby ensuring that all would share equally in the risk of flooding. If realized, River Islands would set a new precedent for in-Delta suburban development.

Oxbow Marina, trailer morphology

Oxbow Marina, trailer morphology

Oxbow Marina was created by breaching the levee wall and allowing water to enter. It is an example of Levee Urbanism principles in use already in the Delta.

Delta Primary and Secondary Zones

Delta Primary and Secondary Zones

The primary and secondary zones regulate land use in the Delta. The primary zone strictly limits uses to those associated with agriculture, and the secondary zone allows uses more loosely associated with agriculture. The secondary zone is the site of many creative interpretations of agricultural uses.

Delta Loop

Pirate’s Lair is part of the Delta Loop, the only existing tourist trail in the Delta.

Captured Sloughs

Captured Sloughs

During the historical period of reclamation, land development companies often filled in waterways to create larger tracts of land. Many of these can clearly be seen in aerial photographs.

Borrow Pit Exchange Authority

Diagram of the Borrow Pit Exchange Authority along I-5. Borrow pits were dug to provide fill for the I-5 roadbed. The pits filled with water and developed riparian habitat. Some are now wildlife preserves. The pits may come back into focus as their locations approximate the proposed Peripheral Canal location.

An Urbanizing Perimeter

An Urbanizing Perimeter

Nearly the entire perimeter of the Delta is undergoing rapid urbanization, making the delta an increasingly important recreational space.

8 Mile Road driving range

8 Mile Road driving range

This driving range is in the Interstate 5 corridor, just off the Eight Mile Road exit at Spanos Park West. The range is part of the leading edge of development flirting with the sea level and regulatory boundary called the Delta Secondary Zone. Much of this development is being done by Alex Spanos, owner of the San Diego Chargers and Stockton favorite son.
