Rebirth: Kearny

REBIRTH

VISION The residents of Kearny will experience improvement from the long term environmental restoration practices and hazard mitigation that will enhance the quality of life and strengthen their sense of community.

GOALS 1. Prevent wildfires 2. Protect and improve the existing economy 3. Promote access & connectivity 4. Produce a native ecosystem 5. Provide flood control strategies

FORMER HYDROLOGY

Flood water flow & future development High point

Flood zone

Old river form This diagram illustrates flood patterns prior to any human disruption of the land.

CURRENT HYDROLOGY

Existing development

Air strip

Pressure points created by mountain washes intersecting river

Flood patterns created as a result of the development and air strip. Mountains & air strip create high water flow speeds causing water to drain back into golf course & development when washes intersect river during flood events.

ECOLOGICAL ANALYSIS Fire Analysis Green Infrastructure Analyisis Flood Analysis

Least ecological importance Moderate ecological importance Most ecological importance

The overlap of analysis diagrams deliniated the most sensitive areas around the town; information which was used to select the most suitable areas for flood control solutions & restoration of native vegetation in areas overtaken by tamarisk trees.

Fire breaks function by progressively reducing both height & density in vegetation as it gets closer to town development in order to increase amount of open space and reduce flammable vegetation.

The site design implents the proposal of wetlands and berms which based on a floods intensity will have a flood pattern sequence. This will help protect areas of the town located in flood zones
