Stormwater Remediation Case Study

When work began to improve the Chesapeake Bay they needed to find the culprits of the bad water quality then get rid of them.

A seawall was implemented at Cronulla beach as a result of the inappropriate development, which occurred, on the very shoreline. A seawall is a form of coastal defence, constructed where the sea, and associated coastal processes, impact directly upon the landforms of the coast. The purpose of a seawall is to protect areas of human habitation, conservation and leisure activities from the action of tides and waves. Specifically in Cronulla, the seawall was administered in order to act as the tertiary dune, which was removed to conserve space that allowed coastal development to proceed. Ultimately, this structure protects the development behind it (such as hotels, restaurants and car park spots), against the waves and tides of the ocean. Hence its vital role is to capture sand and dissipate wave energy; the slight concave structure of the seawall at Cronulla increases the dissipative element of the waves, thus showcasing the Seawall’s efficacy. Such absorption of wave energy means the natural process of erosion is reduced incredibly; consequently leading to the increased stability of the land where infrastructure has been developed. Furthermore, despite the issue of inappropriate development being combated with the implementation of seawalls, there are numerous disadvantages associated with such a structure. The main role of a seawall is to dissipate or reflect incoming wave energy and as

In the ¨River Restoration Project Offers a Sprinkling of Hope¨, Ron Jacobsma, general manager of the Friant Water Authority, said “We hope to get double duty out of that water by taking it the long way around.¨ As Jacobsma is a general manager of the Friant water Authority, this offers us his experience, his ideas and his thoughts of how we can have hope for the project. President Barack Obama signed the Omnibus Public Lands Bill in March, the agreement turned into federal law when he signed it. The parties had been working on the restoration plan for more than two years laying the groundwork for the physical changes to come. When the president signed it, it made them get the approval which he supported for them to continue the process. The credibility of the author right has now been believable because he provided us with the ethics of President Obama and Jacobsma. The river will not necessarily end up to its full, natural path along its entire length. Too much has changed in the decades since the dams construction. They would use canals along some stretches to carry the water short distances and to ferry the salmon upstream. This is showing us logos with facts and information it offers an explanation on how to solve one of the problems with the plan. A professor named Peter Moyole, from UC Davis also had his opinion on the project. He said “We have never done anything on this scale”, but we were willing to try it and approve of the

Think about the following statement: “Only communities located downstream in a watershed need to be concerned about how the water resources are managed in the watershed.” In my opinion, I strongly disagree with this statement. This essay will explain why even communities upstream a watershed should be concerned due to acid rain, and the risk of contaminated drinking water.

This topic is interesting to me because it is a very local issue. I eat the seafood out of the Chesapeake, I fish in many of its tributaries, and I visit many sights built around this watershed. I live in Lancaster County which is focused on in many studies because

issues regarding enviromental degradation and habitat endangerment. There are many issues however some of the more significant problems are erosion, longshore drift and high

The article “Water Works”, published by Orion Magazine and written by environmental specialist Cynthia Barnett intends to inform the reader anyone can make water an important factor. Overlooking it has become common many people in the United States have adapted to through the changes that have occurred in society over time. At the beginning of her article, she describes an area that does not make water care a priority, whereas in another location they make it very evident water is important. The location she describes is gloomy, grey, and is a populated area that has old water systems that are damaging environmental factors. Barnett continuously emphasizes that people are the ones who can help restore nature. This is at a less cost than

The primary goals and objectives of the City’s Stormwater Utility are to proactively maintain the existing stormwater infrastructure and identify the City’s future stormwater system needs and improvements that protect its natural resources, enhances the City’s aesthetics, ensures public safety and improves the quality of life for all who live in and visit our city. This can only be accomplished through partnerships with all city departments, regulatory agencies, developers and the public.

In the early 20th century, the Army Corps of Engineers drained the Everglades and developed plantations as well as other structures, something other settlers of south Florida could not do. The implementation of the organized elimination of water in the Everglades resulted in catastrophe causing massive damage to the ecosystem. Hypersalinity in the southern estuaries and water diverted east poisoned the fresh water estuaries on the Atlantic coast devastating valuable fisheries and marine breeding grounds; saltwater incursion is becoming a serious threat to urban water supplies (Voss, 2000). Voss attended University of California at Berkeley School of Law in 2001 and University of Utah in 1997. The authors is reliable because of the academic achievements he has earned prove he is educated and knows what he's doing but he might have some bias because of his direct affiliation with the Administration of Air and Water Resource and Solid Waste Management Programs and The Central and Southern Florida Project (C &

One of the recurring problems at Howard County is the large quantities of stormwater runoff that flow into nearby streams. This is due to meteorological factors and physical characteristics including: land use changes. The more impervious surfaces there are the more surface runoff there will be; thus, placing adverse effects upon the environment. To be exact, these stormwater runoffs carry car oils, fertilizers, pet waste, litter, and sediment to the Chesapeake bay. Hence, 20% of the chesapeake bay’s pollution is due to stormwater runoff. However, not only does storm water contribute to pollution, but it also harms wildlife and its environment, as well as cause floods, erosion, and property damage. To address such issue, Howard Community College

Now some of you are wondering what any of the last paragraph has to do with the poor water quality in my area. The purpose of that information is to give you an insight on how the politics in this city work, this will help you better understand why the issue what it is and why changes will never

Currently, the way that we use the stormwater runoff is one of the most important issues that was raised, and that was wanting to be discussed. However, green infrastructure is a entire field of thinking for the conveyance of stormwater, and there are many different types of green infrastructure. Due to the variety of different green infrastructure types, the cost of the instastructure will vary, especially when comparing them to the beginning of construction than what typical grey stormwater management costs The main cost savings of green infrastructure are the long term benefits, from the reduction of flooding, and pollution in the water table, to the beautification or our communities. This has been shown in many different cities and urban landscapes, in New York City they calculated that the cost per gallon of storm sewer reduction for the Grey infrastructure was more expensive costing $0.62 per gallon while it only costed. $0.45 per gallon for Green infrastructure. This means that cities are going to be able to save money while reducing the amount of stormwater that enters the storm sewers.

Los Angeles County Beaches have a dangerous amount of water pollutants. The influx of water pollutants has caused water quality in county beaches to significantly decrease, especially with excess storm runoff during the wet weather season. This has contributed to a high incidence of bacteria, like fecal bacteria, which leads to more gastrointestinal illnesses and causes an annual economic loss between $21 to $51 million in public health. Poor water quality in LA County beaches also discourages the public from visiting beaches, putting in jeopardy the estimated $90 billion beach visitors contribute to coastal tourism economy. Therefore, I propose disconnecting the direct link between impervious areas, like roofs or paved surfaces, and the storm or combined sewer system. As this policy is cost-effective, the remaining funds should be utilized to maintain water quality testing facilities and water treatment facilities. This should be done within a year of implementation in order to improve water quality during the wet weather season.

In this case study, the cost of resolving the major issues which are the water quality and air quality issue is too much for Twin Lakes to absorb and at the same time, Twin Lake is also looking at the concession that the City can provide on the taxation of the company owned land as they work together on the resolution to the environmental issues. Once these issues are resolved, all the remaining problem can be easily be settle.

During my senior year four of my friends and I entered into a storm water remediation system design competition that was sponsored by the EPA. The point of the competition was for college students, with the guidance of professors, to create a hypothetical storm water remediation system that would benefit our college campuses. For our project, we created a system that would divulge, filter and use the storm water runoff. This water would have otherwise flown into a drainage pool owned by the city of Burlington Vermont. This drainage pool consistently would fill up with sediment and cost the University of Vermont big money to clean. Our plan was also designed to help curb the amount of pollutants like car oil and liter, that is carried by storm
