WELCOME TO OXFORD BASIN...YOU ARE HERE. Welcome to the new Oxford Basin. In an effort to establish a site identity and branding for Oxford Basin, we developed a theme for signage based on the 2006 Marina del Rey Identity Signage Graphics Package. In addition, proposed signs include wayfinding, circulation information, and interpretive signs.

The wayfinding system emphasizes walking or jogging around the basin along a nature loop. We created tools to help visitors find their way by establishing a color palette and a site icon, the Snowy Egret. Interpretive signs cover history of the site, functional properties of the basin, and native plants and wildlife of the area.

Color Scheme Marina del Rey Identity In an effort to unify Oxford Basin to Marina del Rey, we borrowed part of the color scheme for signage based on the 2006 Marina del Rey Site Identity. The site identity and branding for Oxford Basin borrows color hues from Marina del Reyâ&#x20AC;&#x2122;s identity and together with some special iconography and typography that is special to the site, we strived to establish Oxford as a place of its own, a micro-ecosystem that is part of the bigger ecosystem that is Marina del Rey. The Oxford Basin site identity is reflected but not limited to the proposed signs that include wayfinding signage, circulation information signage, interpretive signage and regulatory signage amongst other possible future endeavors.

RAIN: FROM DRAIN TO OCEAN

During dry weather, water from Marina del Rey’s Basin E moves in and out of Oxford Basin through two pipes that connect the two bodies of water.

Tide gate A is programmed to open during rising tides, sending water from Basin E into Oxford Basin.

When it rains, the water collects in the drains and flow into Oxford Basin. The two tide gates close to hold the water in the basin and release it as the sea level lowers.

Water from Marina del Rey’s Basin E circulates around the vegetated berm improving oxygen levels in Oxford Basin.

Tide gate B closes during high tides and opens to release water from Oxford Basin during falling tides forcing the water to circulate out of Oxford Basin into Marina del Rey’s Basin E.

*NOTE

The tide gate program may vary or be revised depending on weather or other conditions.

TIDES

Tides are periodic rises and falls of bodies of water that are caused by the gravity force between the Earth and Moon. The gravitational attraction of the Moon causes the oceans to bulge out in the direction of the Moon. Due to the rotation of the earth as this happens, two tides typically occur each day.

SPRING TIDES

NEW MOON

Spring tides are strong tides that occur when the Earth, the Sun, and the Moon are in a line. The gravitational forces of the Moon and the Sun both contribute to the tides. Spring tides occur during the full moon and the new moon all year round.

WELCOME

BERM

The Great Egret is another recent resident of Marina del Rey, although in much smaller numbers than the smaller Snowy Egret. The presence of people, along with our cars, boats, and bikes, does not appear to hinder their settlement. In fact, Marina del Rey is one of many examples of developed bays, harbors, marinas, and reservoirs in the region where colonial waterbirds now share space with humans. Oxford Basin is an important foraging area for Great Egrets in the local area.

This dense plant community provides important nesting habitat, foraging habitat and cover for many riparian wildlife species. In coastal Los Angeles County willow scrub often includes the shrubby Narrowleaf Willow, among others.

WELCOME

HABITAT

Great Egrets forage by wading in shallow water, standing on docks, and walking through fields searching for any live prey they can capture. Their diet consists of fish, crustaceans, frogs, and small aquatic life, but they also take on dragonflies, beetles, snakes, mice, and gophers. They will often stand still for long periods waiting for prey to appear; then they use their long neck and dagger-like bill to strike with lightning-speed!

Tide gate A opens during rising tides, sending water from Basin E into Oxford Basin. Water travels around the vegetated berm, until Oxford Basin’s elevation reaches its maximum elevation of 1.5 feet above the mean sea level, and the gate closes. The gate remains closed during falling tides.

FOOD

Habitat: Cosmopolitan, found in many habitats, especially during migration.

BASIN E

Tide Height in Feet

The Snowy Egret feeds on worms, aquatic and terrestrial insects, crustaceans, snails, fish, amphibians and reptiles. Snowy Egrets employ a range of foraging behaviors that include bill-vibrating, head-swaying, hopping, and wing-shading. They frequently use their yellow feet to stir water and sediment, helping to expose prey items.

II Water flows to Oxford Basin.

Although historically considered very sensitive to human disturbance on their breeding grounds, Snowy Egrets have adapted to the conspicuous presence of humans near lakes, reservoirs, estuaries, bays, and marinas up and down the coast of California, where thousands of pairs now breed. Snowy Egrets have become year-round residents of Marina del Rey, breeding in trees and foraging regularly at Oxford Basin, in the marina, and at other nearby wetlands such as the Ballona Freshwater Marsh.

COASTAL SALT MARSH This wetland plant community occurs along the coast where water flows from inland sources. Plants in this community are adapted to a high concentration of salt and oxygen -depleted soils.

Storm drains in Oxford Basin’s watershed collect stormwater and other runoff from over 600 acres. During wet weather, runoff is generated when rain falls on hard surfaces, such as roofs and parking lots. During dry weather, runoff is primarily generated by over -irrigation. As runoff travels to the ocean, it can accumulate pollution such as trash or toxic materials.

When it rains, water can pick up trash and pollution from the streets before flowing into our creeks, lakes, rivers and oceans. Catch basin screens filter debris and trash out of runoff water before it reaches Oxford Basin.

DRY WEATHER: TIDAL EXCHANGE

RAIN: FROM DRAIN TO OCEAN

During dry weather, water from Marina del Rey’s Basin E moves in and out of Oxford Basin through two pipes that connect the two bodies of water.

Tide gate A is programmed to open during rising tides, sending water from Basin E into Oxford Basin.

When it rains, the water collects in the drains and flow into Oxford Basin. The two tide gates close to hold the water in the basin and release it as the sea level lowers.

Water from Marina del Rey’s Basin E circulates around the vegetated berm improving oxygen levels in Oxford Basin.

Tide gate B closes during high tides and opens to release water from Oxford Basin during falling tides forcing the water to circulate out of Oxford Basin into Marina del Rey’s Basin E.

GREAT EGRET HABITAT The Great Egret is another recent resident of Marina del Rey, although in much smaller numbers than the smaller Snowy Egret. The presence of people, along with our cars, boats, and bikes, does not appear to hinder their settlement. In fact, Marina del Rey is one of many examples of developed bays, harbors, marinas, and reservoirs in the region where colonial waterbirds now share space with humans. Oxford Basin is an important foraging area for Great Egrets in the local area.

FOOD

Habitat: Cosmopolitan, found in many habitats, especially during migration.

Snowy Egret Egretta thula

Yellow-rumped Warbler Habitat: Winters widely in urban & suburban settings, marshes & coastal scrub.

Neap tides are weak tides that occur when the gravitational forces of the Moon and Sun are perpendicular to one another in relation to the Earth. Neap tides occur during quarter moons.
