When looking back at the map of marshlands along with the parks of this area, shown in green, possible connections arise for intervention within the floodplain. The two largest parks within the floodplains are Mt. Trashmore (1) park and the Bow Creek Golf Course (2).

By constructing a stormwater infrastructure that allows for floodwaters for be directed away from the current community, we were able to design a path for the marshlands to grow back in this floodplain.

This is integral to the health of the natural habitats in Virginia Beach and will allow for steady land building in this low-lying area of the city. We believe that the residents of Virginia Beach will be able to further connect to each other and the natural environment through this park linkage.

Since the topography of this floodplain was fairly flat, it was important to ensure that the constructed stream gathered runoff from areas of primary importance, while weaving itself through the absolute lowest areas in this location. To ensure maximum performance, a grasshopper script helped to model heavy rainfall events -- thanks to our friends at Generative Landscapes.

Various rainfall models showed that the runoff flowed to the Bow Creek Golf Course, but also throughout the neighborhoods just south of the golf course. The initial design will allow for more water to flow into the golf course as well as out, into the adjacent creeks.

Once the location was found from the rainfall model, another grasshopper script was designed to mimic the cut and fill banks of natural streams.

The set of three above shows the area of consistent water flow (Dark Blue), the bank areas to allow for overflow of 100 year storms (Light Blue), and the initial marshland planting areas that will accommodate for rainfall in excess of the 100 year storm (Turquoise)
