The final design is a liner system that can be quickly deployed to manage large volumes of water caused by storms. This system is cost effective, innovative, extremely applicable to any site, and provides opportunities for added community benefits.
The liner is to be added on a new or existing fence, being four feet up. The liner is then rolled down to the ground, pushed flush against the fence, and rolled out along the dirt three feet. When a storm event is not occurring, then the liner is simply rolled back up and stowed away until the next event. Below are drawings of how this system is to look before and after deployment.
The liner, when there is not a storm event (left figure) is rolled up tightly and stored under roof flashing. This roof flashing adds UV protection, extending the life span on the liner. The liner, when there is a storm (right figure) is flush against the fence and the ground. A 1/2" rebar bar is added to each section of the liner to weight it to the ground, along with a steel stake holding the liner in place.
For Joseph City, a new fence was designed to add infrastructure for the liner to be deployed on. This fence was engineered to withstand a capacity of four feet of water. The components, specific to Joseph City, and their purposes are seen below.
Each liner section is 36 feet long, with six feet of overlap between each section. Below is an elevation and plan view of the liner system while deployed.
There will be a total of 87 sections of liner to be deployed, meaning that this design will span 2,600 feet. Along the total length of the fence and where the liner will be along the ground, the ground will be properly graded to ensure the liner is flush against the dirt.
BACK TO TOPIn order to add a beneficial green space for Joseph City, a community garden was proposed to be on the north east side of the added fence. This community garden will not only create a gathering space for the residents, but an environmental education opportunity as well. During the growing season, the residents can also utilize this space as a way to create a local food system between neighbors. However, as outlined in the community outreach plan, the residents of Joseph City will ultimately decide how to use the green space in a way that best fits their needs.
The proposed site plan is seen below, where the liner/ fence is in red and the community space is in green.
The total cost to design and construct this will be just over $300,000. This includes all material cost, construction cost, and engineering design cost. The table below shows the cost breakdown for the design implementation.
