A Rising Challenge

Global climate change is environmental reaction to increase CO2 levels as a by-product of human action. Increased temperatures, rising sea levels, and intensified natural disasters are all side effects of global climate change. Coastal cities are especially vulnerable, as they contain the majority of the world’s population. The need for archietctural intervention to accommodate environmental changes has become a global priority, as cities struggle to update aging infrastructure. 04

Interventions to protect our cities are of new architectural significance, and are a pivotal factor in imagining the future of the city. For the scope of this research Northeastern University’s School of Architecture has focused on America’s Northeast corridor that lies within FEMA’s designated 100 year flood plain. This lens of the research was further specified by examining cities that are smaller than New York and Boston and will need to envision ways that these cities can effectively pay for better urban space along the waterfront that simultane-

ously activates and protects the city via new infrastructure. Flooding is not merely a U.S. problem but a global one. This research envisions different ways that architects and designers can intervene in this global crisis in order to empower our discipline to effectively engage the social issues of our time. The studio projects that by looking at smaller cities such as providence and new haven along the coast effectively make for better case studies on intervention in smaller cities throughout the world.

Do I need flood insurance?

Do you live in a flood plain?

Yes

Yes. FEMA mandates all structures within the flood plain to be insured. The premiums are set by FEMA, however a private insurer will issue the policy. Contact FEMA to find out which insurers offer policies in your area.

Are you within a storm surge risk area?

Yes

State Farm, Allstate Farmers, Travelers. Many small, local agencies also offer policies.

No, but it is recommended. Contact one of these providers for a quote.

What is Coastal Zone Management?

What is a Flood Plain?

Storm surge an abnormal rise of water due to a storm. It acts like a large, fast moving high tide that floods the surrounding area. The damage from storm surge occurs due to the speed and height of the water moving into an area. One major factor of the height of a storm surge is the angle of the continental shelf along the coast. A shallow shelf will help produce a high storm surge, where as a steep shelf will keep the surge low.

The Coastal Zone Management Act was passed in 1972 to encourage states to be responsible for their own coastal land. The Act allows states to voluntarily develop plans for the maintenance, restoration, and redevelopment of their waterfront. Each plan must include specific provisions relating to protecting natural resources, managing coastal development to minimize damage and loss of life in flood and storm surge zones, increase public access, redeveloping urban waterfronts, and the preservation of coastal features. The specific areas along the waterfront that these programs relate to are also determined by the state.

A flood plain refers to the flat land surrounding a river or waterway that experiences flooding at high water levels. Rather than completely flat the land slopes gently towards the water. The flood plain extends until a physical barrier â&#x20AC;&#x201C; natural or man-made â&#x20AC;&#x201C; stops itâ&#x20AC;&#x2122;s progression, such as a hill slope or a sea wall.

Defining the Flood Plain

What is a 100 Year Flood? A 100 year flood is not a flood that happens once every 100 years, but rather is the level of water expected to be equaled or exceeded every 100 years on average. Based on the expected level of water a predictive flood plain can be mapped out. This flood plain map is then used to inform decisions on building permits, insurance, and zoning.

Coastal Brownfields A brownfield , as defined by the EPA, is a former commercial or industrial site, the future of which is affected by real or perceived contamination. The term is often used to describe under used or abandoned facilities, however it can refer to any real property currently in use. Investing in brownfield reclamation and remediation protects the environment, reduces blight, and saves green spaces and working lands from development.

Heavy Metals Pollutants caused by heavy industry and transportation centers. Includes zinc, lead, nickel, cadmium, chromium, and aluminum. Dry Brownfield - A brownfield site that is not located adjacent to a water source or in a flood zone.

Brownfields are often found in a city’s industrial and commercial sectors. They include buildings such as abandoned factories, refineries, dry cleaning facilities, and gas stations. The contamination found on these sites can include hydrocarbons (oils and fuels), pesticides, heavy metals (lead, nickel, etc.), and asbestos. In the past brownfields were not reclaimed because the cost of cleaning the land was more than the land was worth. There is also the fear of liability for both past and future owners that cause a property to be “moth-balled.” However new liability laws, better remedial strategies, and lack of developable land in urban centers have tipped the scales toward brownfield reclamation despite the costs.

At-Risk Coastal Brownfield - A brownfield site that is located in the FEMA 100 Year Flood Zone.

Coastal Brownfield - A brownfield site that is located in the coastal zone – within 200 feet of a mean, high-tide line. Hydrocarbons Pollutants caused by oil and fuel spills. Includes propane, butane, hexane, heptaine, octane, nonane, and dectane.

Quantity of US Trade

Due to the valuable nature of coastal real estate, waterfronts are often endangered by developers who want to replace the industrial zones with high priced condos and mixed-use development. Due to this demand, the United States government passed the Coastal Zone Management Act in 1972. The act allows states to establish a Coastal Management Zone (CMZ) in order to preserve, establish, and develop working waterfronts within coastal cities.

A working waterfront refers to an industrial area located along the coast and dependant on maritime traffic. A working waterfront can handle national and international trade as well as area waste management and oil refinery. This area often includes ports, commercial buildings, interior and exterior storage, and links to transportation.

The Port of New Haven has five brownfield identified by the city according the the EPA standards. These sites exist primarily along the Mill River waterfront and are located either on the coast or in the 100 Yeear Flood Plain. Most of the contaminants in the soil are heavy metals from industries or hydrocarbons from local oil refineries. 33

After judging different aspects of the site as good or bad, it is possible to overlay the individual maps of desirable areas. A sort of heat map emerges, with the darker areas representing places which are ideal for development. Conversely, areas with a light shade or no color at all are areas with a multitude of problems to be addressed. It is possible to choose whether to attempt perhaps a synthesis of typologies where, for example, rail and area which has very little in the way of opportunity such as cleaning up a brown 22 34

Wetlands are an effective storm surge strategy when used in an urban context. They promote a more accesible waterfront by mitigating grade change, and may be used in combination with recreational space which may be readily flooded in case of a disaster. Wetlands offer environmental benefits through the creation of a new ecosystem while filtering water and preventing erosion. Most importantly, wetlands provide a dynamic buffer zone for flooding diasters, one which may be used in combination with existing infrastructure and proposed program.

One such site on the eastern bank of the harbor could benefit from the construction of a submerged breakwater. The breakwater would serve to define a sheltered port for commercial use while also dissipating destructive hydraulic forces acting on the shore.

Levees Levees in the United States are generally used to direct flood waters away from land, preventing flood water from penetrating into inhabited land. Therefore, they are most commonly found in the Midwest and along the Mississippi River, where fast moving, tall floodwaters cause disasters multiple times per year. As a surge deterrent, levees can be used to buffer coastal cities from storms. However, due to the immense vertical scale needed to prevent a 15-20 foot surge in a 100 year storm, levees as surge protection are expensive to build and maintain. In their current engineered state, they would also cause drastic urban conditions, creating walls, both visual and physical. 82

Floodgates Floodgates are most commonly used as a diversion of floodwater within the United States. They are mostly found on rivers and lakes, and on rare occasions are found in cities. Due to the amount of flooding annually in the Midwest, floodgates are deployed strategically along the Mississippi, Ohio and Missouri Rivers, among others. Typically they are built above urban areas to control the flow of water in the event of a flood. Internationally, floodgates are being used as storm surge barriers in coastal applications. The best use for floodgates are at channels and areas where an ocean meets a bay, harbor or lagoon. There needs to be allowance for ship traffic in these locations, especially high traffic ports such as in the Northeast. Types to use are flap gates and locks. 88

Introducing new ecologies along a flood plain can provide aesthetic benefits, reinvigorate local animal populations, and help cleanse the waterfront. Many organisms can be used as a filtering devise to remove toxins from soils and water run-off. Furthermore, most plantings can provide an absorption base and root foundation that will reduce erosion.

STREAMLINES DEEP GROUND RIVER+CITY+LIFE TOKYO BAY PLAN SUPERHARBOUR

Designing and utilizing a building prototype within the scale of a masterplan can be helpful in creating a new dynamic within the site. Within the flood plain, said prototypes may feature flood resistant qualities or may reimagine the future of the post-industrial waterfront.

STREAMLINES DEEP GROUND RIVER+CITY+LIFE TOKYO BAY PLAN SUPERHARBOUR

Manipulating the ground plane can have immediate benefits along the waterfront. The layering of spaces and activities provides dense development and can be used as a heirarchy in terms flood protection. In addition, the technique can be used to redirect waterflow or introduce new riverlet conditions.

STREAMLINES DEEP GROUND RIVER+CITY+LIFE TOKYO BAY PLAN SUPERHARBOUR

Many of the waterfronts in urban conditions are occupied by industrial sites, most of which are currently under utilized. The land along the working waterfront is prime real estate that could be reclaimed for more public uses. Most industry along the shoreline creates a barrier between the city and the waterfront.

STREAMLINES DEEP GROUND RIVER+CITY+LIFE TOKYO BAY PLAN SUPERHARBOUR

With the majority of the worldâ&#x20AC;&#x2122;s surface covered by water, there is a vast amount of open space that could potentially be built upon. New construction on the water features the benefits of starting completely from scratch. Furthermore, new construction on the water has the potential to gain a key role in shipping infrastructure.

Stoss Landscape Urbanism Minneapolis, MN Approx. 5 sq mi Mississippi River Minneapolis held a competition to foster ideas to reactivate the shoreline along the Mississippi River. Currently there is a strong disconnect between the city and the riverfront.

104 104

Stoss’ entry seeks to remediate some of the issues created by the existing industry while enhancing the existing infrastructure. The water systems are seen as morphing entity, slowly eating away at the surrounding earth to create new riverlets. This concept is carried through to the “stormwater boulevards” that become a system for treating contaminated soils and preventing further pollution of the river. Furthermore, the extension of these streamlines actually brings the river into the city, creating both physical and conceptual connections.

Prototypes are developed as a means to reimagine the industrial areas within the site. Rather than a distinct separation of the two functions, the competition seeks to establish a mixed use district that encourages connections between the established city and the riverfront. Rainwater collection is then absorbed with green roofs and surrounding plantings. These absorption areas become recreation zones for residents, and the excess stormwater run-off is routed in a system of “stormwater boulevards.”

“Stormwater Boulevards” and riverlet expansions extend the watershed into the urban fabric. The system also enables the remediation of contaminated soils.

Ground Lab proposes the revitalization of Longgang river to generate city fabric and create connections with the river. Deep ground becomes the name of the project as it predominantly uses ground and landscape manipulation to create a sectionally rich riverfront.

The goal of the design project, from the office of STOSS Landscape Urbanism, was to implement a series of systems that each have their own task and allow for a more dynamic interaction between the systems. This is a major improvement over the current, static, system that does not allow for the growth and reproduction needs of certain types of local organisms.

TOKYO BAY PLAN, 1960 Kenzo Tange Tokyo, Japan The rapid population growth of Tokyo made it increasingly evident that the current infrastructure was insufficient to satisfy the rising demands. As Tokyo approached a population of ten million, the axial layout of the city created a bottleneck condition downdown. The Tokyo Bay Plan would have likely been home to 5 million people had it been realized. Kenzo Tange approached the plan in terms of transportation infrastructure, envisioning a cyclical chord from which the new city would branch out. The figure-eight-like loops could be built one at a time starting at Tokyo and working across the bay to completion. Offices and government buildings were to be located within the spine while residences were extended into the bay. Industry was imagined occupying the existing shoreline. 110 110

They rise above the infilled ground by 40 meters and vary from 100 to 200 meters in height. Each block is 200 meters by 200 meters. Parking is located near sea level, as is additional greenspace. The municipal blocks have a more organic building composition that points in towards a central park.

Built Environment The figure ground diagram of the built environment shows how industry surrounds the bay while the remaining structures branch out from the central chord.

RESIDENTIAL DISTRICT Similar to several of his other conceptual projects, Tange employs two sloping arches as one of the primary building compositions. This creates a staggered layer of spaces. With varying scale, the design could incorporate a dynamic rhythm to the residential structure. The central space created by the arches serves as a public squares, playgrounds, etc. Access to theses residential outcrops is provided directly off of the main chord and includes monorail service.

The floating houses design project conceptualizes entire neighborhoods and city districts built on water. The houses rely on airtight vessels under the water to keep the house afloat and stabilized. The advantage provided by a floating house is evident, as it is flood proof---rising and falling with tides and storm surges. The community is linked together with a network of barges that act as sidewalks and streets. The network can take on any number of shapes and sizes and can be positioned along any coast. At the end of the barges are a series of docks to allow parking for the residents’ boats. 142 142

The houses sit on plot like traditional buildings, but in the case of a flood, the house separates from its removable foundation to become a floating building. The house will rise and fall with the floodwater. The houses are small in size and can also be moved on truck beds. The floating mechanism works because of the exceedingly simple design of the house. The design shown here uses a shipping container as the body of the house, a reinforced platform, and metal airtight vessels for floating and balance when the land is flooded. 144 144

NEAL CREEK HOUSE HOOD RIVER, OR FAR: .14 PAUL MCKEAN The Neal Creek Residence is a modern example of traditional flood plain response systems. It utilized both a plinth-like concrete structural core and stilts to support all the living space of the home on the upper floor. The lower floor can be used for storage of summertime apparatus and things that are not in danger from floodwater. Below the houseâ&#x20AC;&#x2122;s raised floor is also an outdoor living space providing shade and a wooden deck.

The seaport is by far the most crucial component of the working waterfront. These facilities allow for the shipping and receiving of goods from across the world.

Mixed commercial and industrial space often acts as a buffer between heavy industry and residential zones. There is often overlap in zoning for commercial and industrial building types.

Distribution

Refinery

Food/Fish Terminal

Distribution centers and warehouses are a crucial part in the logistics and shipping network of consumer goods. These facilities tend to be located on the waterfront to have easy access to seaports, rail service and highway infrastructure.

Refineries are a very common building type on the working waterfront. They take advantage of ease of loading materials from large barges in waterways, but do take up a large percentage of waterfront space.

Food and fish terminals line the waterfront of New England. Many towns along the NE Corridor, such as New Bedford, still have an economy heavily based on fishing. Food terminal markets are responsible for the import and export of foods across the globe as well as local goods. 163 163

Goods Distribution facilities rely heavily upon the transportation infrastructure around them. Mass amounts of products are received and shipped on a daily basis, creating a dense network of truck circulation. This makes location, in respect to the flood plain, very important. When products are recieved they are unloaded and stored until that product is required to be shipped. This results in the interior of the buildings to also be very sensitive to the flood plain. Since the majority of storgae occurs on the ground floor, products are at a high risk when these facilities are located in the flood plain

The Fulfillment of Goods

International Manufacturers

Corporate retail offices request product from manufacturers in bulk quantities. These products are then shipped to distribution facilities across the country.

Coas

In addition to product fulfilment of retail locations, distribution centers are often responsible for the shipping of product directly to customers for orders made online or over the phone. Retail corporate offices monitor inventory levels of retail locations and request fulfillment of product be sent from distribution centers. In some cases products will be shipped directly to customers from the manufacturing facility via a third party air delivery service. This is typical if the company owns the manufacturing facility.

Since food product cannot be stored for a long time, the turnover rate is a lot quicker in terminal markets. This results in a very high quantity of trucks that circulate in and out of the facilities. A lot of the product is also temperature sensitive so there is a wider range of storage areas (i.e. cold, frozen, dry etc.) 175

Horizontal Axis Wind Turbine

Coas

Main rotor and shaft and electrical generator are found at the top of the tower. Windmill must be oriented towards the wind in order to be an effective strategy. Turbines generally use a wind sensor coupled with a servo motor.

Body of Water

100 Year Flood Line

Tower will produce turbulence behind it, therefore the turbine should be positioned upwind of the supporting tower. Blades are strategically placed well in front of the tower and sometimes have a tilt built into them.

Vertical Axis Wind Turbine

Windmills Location should be placed behind the 100 year flood line in order to prevent flood damage on the turbine systems

Specific windmilll site design should place the windmills in close proximity to one another, but not overlapping to allow for the maximum amount of wind energy to be collected

The generator and gearbox can be placed near the ground which makes maintenance on the system easier than the horizontal axis system.

Windmill heights can be built to accomodate any height, but the higher the windmill, the greater amount of wind it will receive from less obstruction from objects on the ground

Disadvantages of the this strategy are the low rotational speed with coupled with higher torque and a higher cost of the drive train, and an inherently lower power coefficient.

250â&#x20AC;&#x2122; Smallest distance between windmills in order to have the most effective collection strategy / quantity

WATER SYSTEMS

Main rotor and shaft are arranged vertically. Unlike the horinzontal axis, the vertical axis design does not need to be oritented into the wind in order to be effective. This is advantageouse on sites where the wind direction is highly variable.

Two major critiques of wind turbines are they are visually distracting and noisy. Situating the turbine on the water will make sure that they are not only out of sight, but also far enough away from the inland that their audio level will not be notceable.

The oscillating water column consists of a partially submerged structure that has an opening to the sea below the waterline. As waves enter the air column, they cause the water column to rise and fall. As the wave retreats, the air is drawn back through the turbine. The tapchan consists of a tapered channel that feeds into a reservoir constructed on cliffs above sea level. The narrowing of the channel causes the waves to increase in height. They spill over the walls of the channel into the reservoir and the stored water is then fed through a turbine. The pendulor wave-power device consists of a box, which is open to the sea at one end. A flap is hinged over the opening the waves cause the flap to swing. The motion powers a hydraulic pump and a generator.

WATER SYSTEMS flood plain systems

Wave power comes from the rise and fall of the waves or the fluctuation of pressure beneath the surface of the water. Analysts believe that ocean waves can produce up to 2 terawatts watts of electricity. Wave-power rich areas of the world include the western coasts of Scotland, northern Canada, southern Africa, Australia, and the northeastern and northwestern coasts of the United States.

Pier System

Pier Systems A pier is a raised walkway over water, supported by widely spread piles or pillars. This light structure allows tides and currents to flow almost unhindered below the pier. The solid foundations of a quay and closely spaced piles of a wharf create the effect of a breakwater. Finger piers extending perpendicular to the shoreline essentially maximize the available length of shoreline for ships to berth, allowing ships to dock and unload perpendicular to the shore.

Retaining Sea Wall Beneath the Pier Risk of flooding is much higher then in the other schemes because of the higher water level Boardwalks are typically the base from which piers are built off of. Piers are an extension of the program and activities found on the boardwalk

Space beneath the pier is often an extension of an adjacent beach, and should be considered to be designable and useable space Habitable Space Beneath the Pier

Typical Plan Pier System Boardwalk/Pier street connection needs to be designed to incorporate pedestrian circulation, and vehicular traffic if the site permits it Piers can be designed into any shape or form depending upon design criteria Look-out points should be incorporated into the design in order to utilize the impressive panoramic views Pier width is determined by program: Circulation - 10â&#x20AC;&#x2122; Recreation - 30â&#x20AC;&#x2122;

The pier system was implemented at the chosen location in order to maximize both the infrstructural capabilities of pier in combination with the recreational possibilities. The pier was strategically placed near a local park and multiple sets of pedestrian and vehicular infrastructure. The location ensures a high volume of traffic in and around the site. The pier is also located behind a connecting bridge which will act as a storm barrier that will break up any storm surges. The bridge will make sure that the lifespan of the pier will be lengtheir than a typical pier. As a result, the pier will need less maintenance and repairs.

Slip System

Slip Systems A slip, sometimes called a slipway is the conceptual invese of a pier. It is an extraction into the land, a ramped sectional channel, ratrher than an extension outward from it. Slips are used to move ships or boats from the land to the water. Historically slips would be used as the location for building and repairing boats as well as launching newly constructed ships. Similar to finger pier systems slips break up the wavefront. Source: On the water | Palisade Bay, Guy Nordenson 220

Existing Fill Construction Slip System

Transverse Section Slip System

Angle of slip is dependant upon how deep the slip will travel into the land The deeper the slip travels into the land, the more sustainable benefits it will provide

The existing fill construction method should be used exclusively with the slip system. The existing fill construction method takes the removed earth from the slip excavation and re-uses the earth to create the infrastructural islands found off the coast. The construction method saves materials and money by not importing infill materials. Program should be chosen keeping in mind the risk of flood and storm damage Acceptable slip program includes warehouses, storage facilities, and residences if they are above the 100 year flood level

Slip width is an important factor during design. Most slips should be able to accomodate both incoming and outgoing boat traffic

Slips need to be attached to access roads if they are being used for recreational purposes, however if it is strictly for infrastucture, road access is not required

Artificial Islands Artificial Islands are formed by humans rather than through natural means. They have a long history, historically wooden or stone structures found in still waters. Islands can serve as porous land infill within the watery void of the harbor. Such constructed land in the harbor would help to diminish the force and impcat of storm surge and protect the established neighborhoods and business districts further inland.

Construction Methods Island System

Pillar construction is a very effective construction medthod for deep water island development. Pillar construction allows for island to bebuilt in closer proximately to one another. Pillar construction also allowsfor island to be built in deeper water as opposed to the infill method which needs to be built in shallower water.

Infill construction has a stronger foundation than the pillar method. A negative aspect of the infill methodis that water travel between the islands is limited due to the angle slope required to build theislands. That means the islands must be placed further away from each other, which then forces there to be a longer circulation routes, and more materials incorporated.

Individual island width is determinedby program usage and requirements

Trees are used as both noise and view blockers for pedestrians. The trees block the views back towards the major roadways, and also act as a noise blockers for the vehicular noise coming from the major roadways.

Biking and running paths are incorporated into the park design in order to provide an alternative recreational activity. Paths are often located closer to the body of water in order to seperate the user from the noise pollution of the roads and city.

Open park space is incorporated in order to provide citizens of the city an outdoor venue for concerts and social gatherings. Open space is surrounded by vegetations in order to create physical barriers while also performing acoustic functions.

Artificial island is used as a surge protection, but is mainly used as another recreation area for pedestrians. Create an excellent atmosphere by further seperating the pedestrian away from the noise pollution of the city and surrounding them only with pristine views and water.

The small ferry terminal is layed out efficiently in order to have the shortest circulation routes form the travelers car to the ferry. The distance between the parking lot, the ticket booth, and the ferry access point are often very short distances. The purpose of the ferry terminal is to get get the traveler onto the ferry in the shortest amount of time. Ferry terminals that need to accomodate multiple ferry ships can either have an extended pier so the ferrys can dock on one side, or a shorter, but wider ferry that accomodates ferrys on both sides of the pier. Terminals need to incorporate the pilar method of construction because the terminals are going to be built in deeper waters to accomodate the ferrys.
