Landscape Architecture

Izabella Uribe

The goal of my career as an aspiring landscape architect is to create for the land and ecology at the same time. Using innovative design solutions, I strive to create sustainable landscapes that enhance aesthetics and promote biodiversity and resilience, thereby enhancing the natural environment and enhancing local communities.

For my Capstone Project, I was allowed to transform my site from an untouched oak woodland grove to a more ecological and land-revitalizing space. As someone who grew up around various wildlife, from your typical pet dog to alpacas and cows, I found it essential to understand and ask myself whom I was ultimately designing for. While thinking about whom I was designing for, I was compelled to create a design that would highlight new habitats and also, in turn, help the land itself—designing spaces while restoring the land, building the soil, implementing water capture systems, undergoing phytoremediation, and sequestering carbon.

Constraints

•Land doesn’t provide for all species

•Keeping design to a minimum

•No built structures

•Using natural resources

Opportunities

•Stock Ponds

•Restroom

•Special Status Planting

•Ecological Revitalization

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:

m, environment contribute to oxygen, moistur ca

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.

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.

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.

MCLAREN PARK CASE STUDY

LOCATION: MCLAREN PARK

PARTNERS: BRIANNA CRUZ

YEAR: 2023

A case study examining the current site conditions for McLaren Park. Taking the current constraints of the site and proposing new opportunities contributing to positive ecological and land revitalization.

CURRENT SITE CONDITIONS

EROSION. STEEP HILLS. HUMAN INTERFERENCE.

John McLaren Park was once a part of Rancho Cañada de Guadalupe la Visitación y Rodeo Viejo. The then-governor of Mexico , Juan Bautista Alvarado, granted what is now known as John McLaren Park to the local authorities in 1840.

McLaren Park Legend:

In 1905, subdivisions of the land grant were drawn up and Daniel Burnham issued the Burnham Plan for San Francisco, which recommended that the land where John McLaren and Bayview Parks are today should be reserved for park use.

The Board of Supervisors adopted Resolution No. 26241, New Series on October 4, 1926, directing the purchase of 550 acres for a park planned to be named Mission Park. The Board would rename the planned park in honor of John McLaren's service to the city on November 29, 1926.

McLaren celebrated the dedication of the park in 1927. The widow of Luther Burbank donated ten four-year-old walnut trees to the children of the City. These trees, the ﬁrst to be planted at McLaren Park, were intended to serve as the nucleus of a planned orchard of fruit and nut-bearing trees.

1840 1905 1926 1927 1930s 1958

The Works Progress Administration was responsible for the construction of a scenic drive in the 1930s. At that time, the park also featured a stable and equestrian trails, but horseback riding within the park was later discontinued due to the difficulty of maintaining a separate set of equestrian trails.

Trails

Now the third largest park in San Francisco by area, after Golden Gate Park and the Presidio.

2017

A draft master plan was prepared in 1983, updated in 1988, and issued in 1996, following a 1987 bond passed by San Francisco voters to allocate $2.4 million for major park improvements. The McLaren Park Vision Plan was approved by the Recreation and Parks Commission in 2017.

After multiple attempts to the park boundary recommendations, the park expanded to its present size in 1958 through land purchases.
