Outline Of Development On Site

How does the vegetation surface type affect the amount of runoff? Speculate why this happens.

These tasks go hand and hand with the City Public Works Drainage Division which administrates permits, and is responsible for the implementation and the execution of stormwater best management practices through the use of various resources such as personnel, and medium and heavy equipment. Public Works maintains more than 350 miles of storm sewer drainage system within the City and approximately 150 miles of drainage ditches and thousands of storm water inlets. Public Works crews work continually throughout the year removing trash and debris, mowing drainage ditches, vacuuming stormwater inlets, as well as other tasks to maintain a healthy drainage infrastructure. Unfortunately, the City is faced with the challenges of sustaining its extensive MS4 program and existing drainage infrastructure due to the lack of additional financial resources. Certain sections of the City’s drainage system are more than 50 years old and deteriorating. As the City continues to grow and expand, the need for repairs, retrofitting and maintaining the City’s existing infrastructure is as equally important as creating new capital projects.

Storm water runoff gets formed by man-made areas such as driveways, parking areas and roofs. All of these types of surfaces are waterproof surfaces, so when they are placed around lakes, they tend to collect and transport precipitation over the land instead of allowing the water to penetrate into the soil. Storm water runoff affects the soil greatly along with all of the wild life and vegetation that needs the soil to live and form. That is the reason that areas of land around the lakes in Michigan have soil with lesser value than other

Smart planning and using green technologies can reduce the impact that urbanization and growing populations puts on the Bay. Pervious paving surfaces reduce the amount of runoff going into the Bay. There are many benefits to using pervious concrete, “these benefits are achieved with the use of an innovative design. Pervious pavement, also referred to as porous or permeable pavement, is actually a system consisting of an open-graded surface layer of concrete, asphalt, or pavers, typically placed over an open-graded aggregate base layer. The pavement structure has a large percentage of void spaces allowing water to permeate through the surface and base at a rate comparable to that of a grass lawn” (Broviak). Strict stormwater control measures have recently been passed in states surrounding the Chesapeake’s watershed, including Maryland, and many require a certain amount of green space or use of green technologies in construction. In addition to the growing use of pervious pavement techniques, other types of stormwater management techniques are gaining popularity. In a thesis paper from University of Maryland, Wilson discusses alternative ways to engineer for the Bay; “By using technologies such as cisterns, green roofs, and constructed wetlands, the built environment can be designed to decrease our need for expensive water purifying infrastructure and preserve the health of fragile estuary ecosystems such as the Chesapeake Bay.” Rain gardens are a viable alternative to storm drains to deal with runoff from impervious areas. A rain garden captures water that would usually run into a storm drain and eventually be discharged into a river and allows it to infiltrate into the ground and for evapotranspiration to occur. In a study done to evaluate how effective rain gardens are at capturing and reducing runoff results were

In module 6, the part I found most valuable was the Deliberate Development Plan. I enjoyed learning about how to make a step by step plan to develop an Airman. Deliberate Development Plan is more than just mentoring an Airman by telling them to do something to help their career. From the module, I got to understand that Deliberate Development Plan involves breaking down a plan of action for a particular Airman to help him reach his goals. Deliberate is the time it takes to look over or talk about the goals carefully. Develop is to create or make the steps needed to reach the goals. Plan is the path you help the Airman to take to get to their goals.

Most of the catchments depicted in Figure 1 where fully urbanised which caused surfaces in the catchment to be impervious; that is very little runoff would infiltrate into the ground

These nearby areas also implement a National Pollutant Discharge Elimination System, and NDPES. To control and systematically fight off hazards, there is an intial phase of obtaining an NDPES permit. This permit works hand in hand with a Stormwater Pollution Prevention Plan, an SWPPP. The SWPPP describes the new project site that is being proposed usage. Essentially it details the means in which will help keep the area safe as well as its maintenance for potential incoming

Houston has major flooding because of Hurricane Harvey. Harvey was a major hurricane that lasted about a week (August 25 - September 2). Experts aren’t exactly sure how long it will take for Houston to be unflooded, perhaps weeks. Since a lot of Houston's surface is airtight the water is having a hard time escaping. According to Richard Luthy, “There is no rapid drainage system.” The two reservoirs that Houston have are at full capacity. The reservoirs are supposed to hold the water from extreme storms like Harvey. The Army Corp is having to slowly release some of the water from the reservoirs in case of breakage. Many of the lands are made out of clay so the vast amount of water is causing some of the land to sink. The amount of water that

The dam should be intended to decrease the measure of silt that are kept upstream and to augment the residue downstream.

Municipalities charge stormwater fees to help pay for management of water runoff to avoid flooding and to help clean polluted runoff that makes its way into streams and lakes. By allowing water to seep into the soil on your property, you are helping the environment by letting the water go through its natural filtration process. You're also protecting your community because your lot won't add to water volume that could flood your neighborhood during a heavy

A: Some methods to prevent soil erosion are, planting vegetation because it lessens the impact of rainfall to soil. Another method is to build retaining walls because The retaining wall will act as a shield for the soil and prevent soil erosion from occurring. Yet another method that I have seen used regularly is tarpping and sand bagging. This is where you take large plastic sheets, or tarps and lay them down on the area in which you wish to prevent erosion. Then the sand bags are placed along the edges to keep the tarp from blowing away. These methods do not completely stop erosion all together, but they do lessen the time it would originally take without any protection.

The texts from this reading list for the Erosion Control Structure Unit will be used as starting points for each of the topics to be discussed in the classroom. Topics for this unit in order are: general conservation, terraces and tile, ponds and spillways, and careers. Students will be assigned one reading in preparation for a new topic in class, and the three texts with different Lexile scores will provide students to read a text appropriate to their reading level. At the start of class, the discussion will be focused and based on the information the students read for homework. I will ask for questions students would like to explore or learn more about in the topic area. These questions will serve as a majority of the lessons material and

In this project, Retaining Wall was designed to serve the purpose of supporting levelled ground. The site mostly consisted of gravelly sand with 5-10% silt. This served as a backfill material to the retaining wall. In addition to this, the backfill was filled with crushed boulders covered with sand serving the levelling purposes.

Water purification and a wastewater treatment plants would be necessary in order to provide the citizens and visitors with clean healthy water. To prevent flooding, this city was built on flood plains.
