Bunker Revitalization unker

water enters tree where contamination is cleaned up

Carbon Sequestration:

Biological carbon sequestration: Through dense planting of the site, as well as planting in the already built bunkers. CO2 binds to plants during photosynthesis, exchanging it for oxygen as a purifying emission.

Geological carbon sequestration: Carbon dioxide is stored in underground geologic formations, such as rocks. When fossil fuels are captured and stored, they can be used until an alternative source of energy is introduced.

tree roots take in water and contamination from the ground

Clean Soil

Living Wall:

Allowing the wall to be taken over by both plants and animals. Plants roots are thin and can grow through the cement. Birds can build nests in the cracks of the abandoned bunkers.

Phytoremediation:

Phytoremediation involves using plants to clean up contaminated environments. Many contaminants can be removed by plants, including metals, pesticides, explosives and oil.

Natural processes can help plants clean up contaminants as deeply as their roots can reach, such as:

•Store contaminants in roots, stems, or leaves.

•They can be converted to less harmful chemicals in the root zone or within the plant.

•Vaporize them and release them into the air.

•In the soil, contaminants can sorb (stick to) the roots, where “microbes” live.

Composting Toilet

Bio-decomposition breaks down solid waste material in composting toilets. Waste is mixed with bulking agents such as wood shavings to boost aerobic conditions. During the composting process, the warm, moist environment speeds up the breakdown of the waste.

The Composting Stages:

There are 4 factors that contribute to composting: oxygen, moisture, temperature, and the right carbon/nitrogen ratio. Each 'contribution' is balanced with 2-3 scoops of sawdust (sawdust absorbs all the nitrogen rich human contributions).

Stage 1: As the compost eats, reproduces, and creates heat, mesophilic bacteria eventually transition to halophilic bacteria at 44-52°C (111-125°F)

Stage 2: It is the thermophilic bacteria that thrive in higher temperatures, taking over and creating heat, sometimes reaching 70°C. This process can take months, days, or even weeks to complete. As it cools down again we reach

Stage 3: More diverse organisms such as fungi and earthworms move in and digest larger, coarser materials.

Stage 4: Curing/maturing is a long and important phase. It is important that long curing periods (e.g., one year in the temperate and half a year in the tropics) are employed to ensure pathogen destruction after the thermophilic stage. Microbiological competition in the compost pile will most likely kill them quickly the longer they are exposed to it. Soil food webs are involved in all of this.

Building

Restroom Habitat

The built structure used for the restroom could double as a habitat for the yellow-headed blackbird.

Introducing new spaces to act as places for habitat allows the introduction of more species to Army point.

Stock Pond

Watering ponds for livestock have been constructed as a water source in rangeland settings. Enhancing existing stock ponds can result in improved water quality for livestock and the creation of wildlife habitats. Ponds can be magnets for wildlife, large and small, such as California red-legged frogs and the Pacific Pond Turtle. Tree frogs (aka chorus frogs), birds, bats, and other mammals also benefit significantly from the water availability and habitat provided by stock ponds.

These pond can be used for irrigating the site (based on amount of water).

Stock ponds have the potential to act as a form of erosion control.

ponds act as a carbon sink

Habitat Introduction

Stock ponds allow for different species to come and thrive on new land. Other species means new prey and predators coming to the area, expanding the fauna palette on the site.

The western pond turtle being one of those species playing a new role in this ecosystem.
