Above: my groups 40 and 20 yr Plan of Hunters Point SF
As a Landscape Architect, one’s design should never stop short of aesthetic. An intervention should be holistically progressive. There have been a handful of loaded words I hear quite frequently in the studio; “Green”, “Sustainable”, “Eco Friendly”. While the root philosophies are something I agree with, I question the validity of its practiced actions and the extent to which it is really “Sustainable”. We admit now that our current population and way of living cannot be supported by the limited resources available. We are having problems, should we “sustain” this imbalance?
There are talks of a carbon zero city outside Dubai. Nothing can be carbon zero. The initial construction of an entire city will bury any shining low energy consumption graphs in environmental debt. Its less impactful to continue to drive an SUV than it is to buy a new Prius, given the environmental cost of manufacturing an entirely new vehicle. We need to redress our current actions and determine whether or not we are satisfying our ideals. Landscape Architects should be forerunners in this cause.
Last year, I participated in a studio that discussed the idea of sustainability. We figured out (under the guidance of a very intelligent Prof.) that for something to be truly zero carbon or sustainable, it needs to be productive. This is the only way that the carbon footprint of a project can be taken back after implementation. But, there always seems to be a trend with going “green” in pristine areas, building LEED certified auto factories on an existing meadow. I question how “green” does a factory have to be before it disappears, no matter how many solar panels it has, and whether or not its insulated in recycled denim and cardboard, there will be a factory on a meadow. What I’m trying to say is that it only works if the project is an intervention, if you’re solving a problem. Our instructor selected Hunter’s Point as our “problem”. Hunter’s Point is located at the Southeastern tip on a man-made peninsula, in San Francisco. Hunter’s Point used to be a thriving navy base, and this was where the shipped off the bombs that destroyed Hiroshima and Nagasaki. The surrounding community possesses the lowest income levels within San Francisco. The site is also a Superfund site, meaning that the government has allotted a super fund of a great deal of money to deal with it. The reason being is that the entire abandoned military base is peppered (or super super soaked) in carcinogenic and mutagenic waste from the Bomb development. San Francisco is dealing with the site by building around it, and they are dealing with the community by gentrifying it. They have yet to invent an emoticon for a sarcastic smile. Lennar (a ca development company has produced a plan with a team of architects and landscape architects.

Lennar’s plan centers around a new stadium and a retail and restaurant district. The homes are low density on somewhat large plots of land, much desired in sf but rarely affordable. They base their phases of development on the cleanliness of each area’s soil, starting with the cleanest first. I pray for whatever po’dunk town receives a big shipment of excavated radioactive soil.
This plan is not sustainable, economically, environmentally, and definitely not socially.
Lennar: FAIL
Our class came up with a couple of ideas, from as small as compost “Plants” to as extreme as turning the entire site into a salt marsh and bio science museum. It was up to us (hypothetically) to create a development plan. Our group understood that development had to happen, it was inevitable, but how? Is it right to send SF’s poisoned soil else where? Was it right to build on top of it? Also, we started brainstorming about an independent sector of SF that utilized its waterfront, and produced its own food, offered different sizes of homes and free’d up space for parks. My brilliant team members and I determined, yes there is a way to fix this and even profit from it. How American is that? We were familiar with the process of phytoremediation ( the use of ceratin plants that remove toxins from the soil), we were quick to map out the site and its toxicity, using USDA charts and reports. We determined all the toxins, and found plant species that cleaned everything. Also, we could harvest those plants and use the elements they collect. We can use Mustard plants to remove lead, burn the mustard, and collect the lead. The only issue with this, is that the process only removes toxins that make contact with the roots. The lower levels of toxicity are undisturbed.
This is my solution:

If the contaminated soil from the entire site was excavated and regraded in the above example the toxins would be removed in 40 years. The PR Park harnesses the powers of phytoremediation and activated carbon “canyons” (think brita filter) and turns a toxic landfill into a sculptural park that simulates rare California coastal ecosystems.
So instead of building over a problem, or sustaining new development, we took a chunk of land back, reclaimed it, and produced something beautiful.
Not sustainable, but productive.
