The original coast line of Mississippi is shown above. Below is is the larger sire located south of the air force base along the Biloxi Coast.

PROPOSED CONCEPT
The masterplan above demonstrates how a series of individual salt marshes can exist in a linear form across the coast. These series of salt marshes form a sort of linear approach along the coast, but are seperated in case they become unstable. If one salt marsh fails, another may last unaffected by it’s neighbor. Small islands exist in front of the areas where the marsh meets the ocean to prevent erosion due to current and allow the salt marshes to flourish. Certain portions of the beach extend outward into the water to help prevent erosion, create more variety along the beach and help to encourage research. A hook shaped portion extends off of the shore to create a mini loop current in the ocean, which is the same current along the gulf. These individual salt marshed can be developed in a series of phases as each one would cost quite a bit to dredge, but once it is cut into the ground, it requires no upkeep.

100 ACRE CONCEPT
This highlights the barrier island in front of the entrance to the tidal salt marsh to deter a strong current from entering the area. The salf marsh goes under highway 90. The underside of highway 90 is harscaped to protect from further erosion underneath it. It is the only hardscaped portion of the dredged salt marsh. The salt marsh extends inland to the natural drainage areas on land according to the GIS map and then in the undeveloped, dead zones along the coast. This woudl ensure that residents can keep their homes and stores wouldn’t need to move. Instead the abandoned land would no longer be left unkept.

Above is a circulation map which shows raods, parks and sidewalks. To the right are a series of flood diagrams showing what high tide vs 8 feet vs 16 feet flooding. This would allow the protection of all buildings around the area in the case of most storm surges and flooding.

10 ACRE CONCEPT
By directing the flow of water and people surrounding it, the environment is better protected. Creating a series of tidal salt marshes which extend inland create an area for flooding and storwater runoff to flow to. A salt marsh also introduces a new ecosystem inland to support more wildlife and sustain better research. Around these salt marshes are some linear parks which exists right above the flood zone. This allows for community recreational use which is withdrawn from and town of city life. These parks would be surrounded in forest which would allow you to see peaks of the salt marsh, but otherwise leaving it undisturbed, Above the flood zone and in the more industrialized area are smaller retention areas, which can exist as small parks or forests. These ‘ponds’ are extremely shallow in depth and would only ever be filled during a major storm.

THE AMPITHEATER
The ampitheater is located near the center of the site. There are developed raised gardens along the deeper end of the steps. These same gardens follow the contour of the inner portion of the theater. Though this could be used as a theater, it is also used as a park along the salt marsh. Through windows in the walls holding up solar panels, glimpses of the salt marsh below can be seen. This was primarily designed as a green space park area for public access.
THE OVERLOOK
An area located on the other side of the site which was mostly designed in a yin yang format. This is created for locals and residents nearby to use. It provides a more private view as well as a small sitting area. It borders the street crossing over the salt marsh so cars could park and people would be aware of this place in the area. Solar panels border the edges of this view for extra shading and providing power. A bridge along this street provides additional shade. It’s design adds to the site.
THE PAVILLION
The pavillion is one of the centerpieces of this design as it follows the path of the yin yang form. It is developed at the meeting of people from both sides of the salt marsh. It is designed to create interest and make people want to spend time in it. It provides a view of the buildings and salt marsh around it.

Solar Panels are located along various portions of the walkway surrounding the site. They have a series of four different sizes with two additional stacked forms. There are a total of six variations
These solar panaels cover about 6,000 square feet of PV cells. The remaining needed to give required power supply is gathered from two walls to on of the buildings. These PV cells lie in the exoskeleton of the western wall and on the wall facing the south.

3 ACRE CONCEPT
An exoskeleton surrounds the exterior of the building to connect it to the surrounding site as well as give it a structure at the boom for additional support. Above lie a series of two balconies which connect all the buildings above the flood zone. Underneath is a large o pen space for recreational use and flooding problems.
The above two images deom strate what happens to the podia of the building during the start of a storm and the end when there is severe flooding. At the back side of the building is an entrace which has a grand stair case leading to the floor connecting all buildings above.
