The Brownfield Problem
Brownfields are abandoned, idled, or under-used industrial and commercial sites where expansion or redevelopment is complicated by real, or perceived environmental contamination that can add cost, time, and uncertainty to the redevelopment process. Throughout the country there are an estimated 450,000 brownfields. These vacant properties exist mostly in cities, serving no practical purpose, and act as both eyesores and environmental as well as economic pitfalls. The inner cities, where most brownfields exist, were once the only choice developers had in deciding where to build industry. However, since the birth of environmental laws and regulation, the redevelopment of these properties has become a complicated and often very costly procedure. This procedure causes many businesses and corporations to look outside of the inner cities and urban areas for locations to grow and develop. This trend not only leaves the inner cities vacant and economically useless, but also leads to urban sprawl, a phenomenon that leads to the development of greenfields, or the pristine, undeveloped land outside the confines of massive urban areas.
Many sites across the country that were once used for industrial, and/or, commercial use have been abandoned by the companies who used them. Some of these sites are contaminated; however, some of them are merely perceived as being contaminated. In those cases, the sites have been linked to big industry, or nearby sites. In the past, any such site has been avoided or ignored as a possibility for redevelopment. This situation is caused largely by federal and state environmental laws and court decisions that impose or imply potentially serious liability. The circumstances surrounding this uncertain liability has encouraged businesses to build in previously undeveloped and non-urban areas, that are referred to as greenfields, where they are confident that no previous industry has been active. A report from the General Accounting Office finds that: "As states and localities attempt to redevelop their abandoned industrial sites, they have faced a number of obstacles, including the possibility of contamination and the associated liability for cleanup." This situation has lead to a number of far-reaching problems including social, economic, and enviro...

...ization to determine the extent of environmental contamination and the cost of removal or remediation. Then, funds should be set aside either from the Superfund Trust Fund or general revenues to provide resources to local governments to develop brownfield site inventories, site assessments, and brownfield redevelopment strategies, the main goal of which would be to attract private investment. EPA should expand their Brownfields Initiative to include funds for preparation and implementation of brownfield redevelopment strategies. Federal funds should be made available for the creation and capitalization of local revolving loan funds for local governments or the private sector to perform activities such as removal, remediation, and small business development at brownfield sites. HUD should provide resources to accelerate actual development, through leveraging private sector investment and other means, to move beyond cleanup and remediation. All agencies need to find ways to assist by providing resources that will aid in the redevelopment of brownfield sites.

In conclusion, brownfield redevelopment supports the continual goal of sustainability through utilization, incorporation, preservation and remediation. For instance, brownfield sites offer developers a chance to utilize the existing infrastructure, which lowers municipal costs. Additionally, developers can incorporate ancient and modern technologies that create more efficient buildings thus reducing energy use. Moreover, with opportunities to grow within cities, there is less pressure to develop greenfields. Furthermore, through the required process of remediation, environmental hazards are removed or prevented. Overall, brownfield redevelopment saves money, reduces energy usage, protects greenfields and removes critical dangers to the surrounding environment thus moving towards a more sustainable society.
An aging population, a younger generation who prefer walkable places, economic shifts, and the environmental impacts of suburban development are all contributing factors” (Beatz 141). Reshaping Metropolitan America gives an argument, as well as a blueprint, on how we can transform our infrastructure and housing demands by 2030.
The United States Environmental Protection Agency (2005) defines mountaintop removal as “a mining practice where the tops of mountains are removed, exposing the seams of coal.” Coal companies throughout Appalachia adopted this process as a means of acquiring coal faster. People in support of mountaintop removal concentrate, not only on the cheap, plentiful energy which is produced, but also the supposed increase in safer occupation opportunities for miners. Such individuals also argue that flattened land provides space for airports, prisons, and shopping centers. However, mountaintop removal has serious consequences, which need to be revealed.
A new phenomenon happening in our city is the rebirth of many of our older and rundown areas. One of the best examples of this is the "Soulard" area of town, which now has an established nightlife as well as exquisite historical antique homes. Lafayette Square has also enjoyed the same type of success as Soulard. It is still in the middle of a high crime area, but is populated by upper-class people with beautiful homes with elaborate wrought iron fences and intricate security systems. This trend of fixing up old flats is spreading out from the areas of Soulard and Lafayette Square to neighboring communities at a rapid pace. The Compton Heights area is coming back with rebuilt old Victorian styled houses and private gated streets that contrast the French styled flats of Soulard. The Shaw and Tower Grove area are also following the lead of revitalization similar to these charming old neighborhoods.

Residential, commercial and industrial development is the largest contributors to landscape change in the state of New Jersey. When buildout occurs in one region, development pressure begins in another, virtually insuring the Megalopolis concept of one huge urban corridor stretching between Boston and Washington D.C. Year after year, farmland dwindles, roads become congested, and more residents are left to compete for diminishing natural resources. Desperate measures and newer technologies are incorporated to replace poor planning and lack of vision on behalf of decision-makers caught between competing interests. When the long term health and wellbeing of the established population and the short term gain of a limited number of people compete for vital natural resources there should be no question who's interests should prevail.
For example experts argued that the siting of landfills in Warren County made no scientific sense. This explains that the pollution sources are purposely placed in the vicinity of minorities despite the knowledge of the fact that it will the residents drinking water. Also, as shown in the article, “Environmental justice: Income, Race, and Health, “... Asthma prevalence in the U.S in significantly higher in minority and low-income populations than in the general population. Unequal exposure to environmental factors that triggers or exacerbate asthma may play a role.” This shows how the government places hazardous companies in minority dominant communities, which exposes them to toxic hazardous and unsafe conditions. This demonstrates how environmental racism is marked by contamination from different sources of
The decay of social elements of urban areas is one of many factors that has led urban developers to pursue a new strategy known as urban infill development. Urban infill development seeks to create more sustainable urban areas by both halting the expansion of suburban sprawl and revitalizing urban centers by redeveloping previously developed sites (http://www.rff.org/rff/documents/RFF-DP-10-13.pdf). Successful infill development can increase density, enrich the physical appeal of the area, heighten the perceived sense of safety in urban areas, and, of course, build community. However, infill development faces challenges...
In the 1930’s before the Love Canal area was turned into neighborhoods, the Hooker Chemical Company purchased the area and used it as a burial site for 20,000 metric tons of chemicals. In 1953 the Hooker Chemical Company sold the land to the Niagara Falls Board of Education for $1.00. There was a stipulation in the deed, which stated that if anyone incurred physical harm or death because of their buried wastes, they would not be responsible. Shortly after, the land changed hands yet again and this time home building began directly adjacent to the canal. Families who bought homes here were unaware of the waste buried in their backyards.
Walk down any street in small town USA and look around, there are empty buildings splatted between empty lots, trash and parking lots. A glance at one of the empty buildings and a sense of people bustling about carrying packages, dressed in early nineteenth century clothing plays out in the mind like on a movie screen. Why is it not being brought back to life? Turning a group of people are standing in front of it with blueprints open and smiles on their faces. A sigh escapes; there is hope for the neighborhood thanks to people with vision and planners who see potential behind the empty windows. In time this areas like this will go from an eye sore to a place where people live, work and enjoy an evening meal. Chen states, “The image of decay, indifference and crime was turned into a sense of roots and a feeling of community pride. (Chen, 2013, pg. 835) Using comprehensive planning and developing a balance between urban planning and historic preservation will add economic and environmental value to our communities.
Indeed, many global cities face compelling urban planning issues like urban sprawl, population, low density development, overuse of non-renewable natural recourses, social inequities and environmental degradation. These issues affect the cities themselves, the adjacent regions and often even globally. The resulting ecological footprint upsets the balance in adjacent rural and natural areas. Unplanned or organic development leads to urban sprawl, traffic problems, pollution and slums (as evident in the case of Mumbai city). Such unplanned development causes solid waste management and water supply to fall inadequate. Urban sprawl gives rise to low density development and car dependent communities, consequently leading to increased urban flooding, low energy efficiency, longer travel time and destruction of croplands, forests and open spaces for development.
...emonstrated above each group identified has a chance to police and control the operation of these facilities. They all can choose to pass the buck and blame someone else; or they can step up and take control. We all have an ethical responsibility to do what is right. We need to protect the environment while ensuring human prosperity. The Government is here for us, they work for us and we must ensure that they do what we want, not what is best for industry or big business.
First of all, overpopulation drastically affects the land. Possibly the most prominent example of the depreciating health and amount of land is the need for developments. Due to the exploding population in the United States, about 1.2 million acres of land every year is being converted to subdivisions, malls, workplaces, roads, parking lots, resorts, and many other developments (“Overpopulation,” Internet). That is a substantial amount of land being overturned to satisfy human desires. To put it in better perspective, between 1982 and 1997, the land mass lost to development is equal to the size of Maine and New Hampshire combined, which is approximately 25 million acres (“Overpopulation,” Internet). While soil is being ruptured for human preference, the number of cities has remarkably modified. In 1975, Mexico City, Tokyo, and New York City were the only cities considered as megacities (“Special,” Internet). In today’s world, that number is considerably small. Now, there are 21 megacities in the world. A megacity is when the population of that city becomes greater than 10 million people (“Special,” Internet). Therefore, the 21 megacities that are currently in the world holds more than 21...
