2. EXECUTIVE SUMMARY
Introduction
Design connect, DE&ED, and the International Planning Student Organization have come together
in response to the January 12, Haitian earthquake. Bringing together a wide variety of backgrounds
in architecture, engineering, landscape architecture, and city planning the team has created a design-
based response for housing those displaced by the disaster.
The following document explores the ideal qualities that should be considered when:
• Selecting a site for a new community development
• Planning infrastructural layout needs of such a site
• Designing construction techniques that can be used to maximize the health, safety, and well
being of the new residents.
This draft is an example of the design services Cornell can offer. The following work should be
considered as design suggestions and strategies rather than finalized solutions.
SITE SELECTION
Criteria to consider when selecting a site for Haitian refugees revolve around three primary factors
regarding the site’s physical features, legal & political conditions and off-site conditions. These
criteria are ranked by importance in the table found in the Appendix.
Physical Factors: Soil type, depth to bedrock, water table, slope, elevation, on site water bodies,
vegetation, topography, pollution, installed utilities, buildings, fences, bridges, transportation access
and the site’s prior history.
Legal and Political Factors: Federal and state regulations, past & current zoning, potential rights-of
way, building codes, number and types of neighborhood associations and special interest groups,
local community attitudes toward development, transitional community size, location and function of
NGO’s and Multilateral Aid groups, food and water distribution, and safety.
Off-Site Factors: Proximity to incompatible land uses (city dump, heavy industry), transportation,
community services, and employment centers.
3. EXECUTIVE SUMMARY
INFRASTRUCTURE + LAYOUT
• Primary and secondary streets should be laid out first to secure access for service, construction,
and emergency vehicles.
• Street-side ditches could direct storm water runoff to treatment/infiltration areas in order to
prevent flooding and disease.
• Construction support facilities may include rubble processing equipment, training, employment,
dormitories, and materials storage
• An infrastructure grid could be laid for water, electricity, and sewer lines (where possible) to core
infrastructure units
• Ready-to-build home sites might be laid out on a common foundation surrounding shared core
infrastructure units. Previously constructed areas might retain prior parcels for continuity.
• Prime commercial sites along primary roads may be sold to businesses to subsidize low-cost
interior home sites and provide additional services and employment.
• Key facilities such as job dispatch and food/fuel distribution centers, security/fire departments,
counseling and health clinics could be constructed at primary street intersections. Community
facilities (such schools, churches, community centers) could be constructed at secondary street
intersections.
CONSTRUCTION STRATEGIES
• Construction should be designed and engineered appropriately so as to protect residents from the
rain/hurricane season and withstand earthquake aftershocks
• Construction strategies might focus on training, distribution of guidelines, and creation of jobs
• Techniques may be chosen to use materials that are readily available such as processed rubble,
concrete masonry units, sand, wire, plastics, fibers, crates, and/or corrugated metal sheets.
• Consider stable foundations to prevent flooding and appropriate roof and wall geometries/
reinforcement to minimize hurricane and earthquake damage
• Construction methods could be chosen based on cost and time constraints
• Transitional shelters may eventually be incorporated into reconstruction
• Phasing of construction is a possibility to allow residents to move in as soon as possible. Pre-
fabricated tents can be set up on foundations to provide flood proof shelter. The tent can become a
roof as walls are constructed underneath.
4. SITE SELECTION
SITE SELECTION MATRIX
Location Is the site located near to potential employment areas? What is the
condition of the existing buildings in the area? Is it near existing
gathering areas?
Size Does the site have the minimum amount of acres required for
development, but not too many acres? Can the site situate a minimum
amount of 10,000 people? Displaced people's gathering site should
be below 20,000.
Site Acquisition What is the total cost of land? Who owns the land? Is land
ownership at the federal or communal level?
Former Site Uses Will previous uses require additional development costs to mitigate or
in any way adversely affect the quality-of-life?
Topography Is the slope rate under 25%? Are there any risks of landslides? Is the
land suitable for spaces for aid delivery, allowing for easy distribution
and queuing?
Geological and Soil Conditions Will the soil conditions adversely affect on refugees? Does the soil
allow proper water drainage? How deep is bedrock below the site?
Ideally we want it to be under 8 feet. Is the site located within 25 feet
of any fault lines?
Flood Potential, wetlands Is the site located in a floodplain? Does the topography have good
drainage? Could the site create a condition for the creation of ponds,
leading to malaria outbreaks?
Vegetation Does the site possess desirable mature vegetation? What percentage
of the site is covered with vegetation? If not, is the site paved with
materials that have a low SRI (solar reflective index) that could result
in heat island effect?
Existing Utilities Are city or county utilities present and available for use? How close
is the site to wells? Does the site have good drainage for waste? Is
there existing access to power?
Existing Transportation Are existing roads in good condition? Can they handle both access
and impact of planned development? Do the roads allow easy access
to freeway or other major arterial roads? Is the site near ports or
airports? Does the site allow easy access for sanitation, freight and
emergency access vehicles?
Proximity to Relief & Services Is the site located within acceptable travel distance for relief
organizations? Are there any clinics/hospitals located nearby? Is it
close to a supply distribution center? Are there any bases for
enforcement nearby?
Adjacent Property Uses What are the adjacent properties used for? Will placing this site
negatively affect surrounding neighborhoods?

6. SITE SELECTION
The number of Internally Displaced Settlements has continued to increase. These settlements consist
of several hundred makeshift tent structures that typically average seven people. While the number
of people varies per settlement, nearly 5,000 people reside on several scattered sites about the size of
a soccer field, roughly 73,000 square feet. Settlements should be formed near areas that have good
physical features and are easily accessible.
SITE 1
Site 1 has many of the ideal qualities
for housing internally displaced
persons. It is near two major roads,
the Mais Gate International Airport,
and the new UN Headquarters. The
site was previously zoned as an
industrial site major, resulting in
water utility lines being installed on
the property. Drainage and storm
water can be easily managed based
on the site’s higher elevation. The
one kilometer, or 10,763,910 square
foot, site is large enough to house at
least three communities.

proposed that as growth
exceeds accessibility,
new staging facilities be
constructed to continue
growth.

13. KEY QUESTIONS
SITE SELECTION
• How much open space is there in or on the outskirts of Port au Prince? Who are the owners or
stakeholders?
• Are there any large hazardous areas in the metro area? (For example, large bodies of stagnant
water, abandoned industrial sites, burning trash dumps, etc)
• After the earthquake, will there be centralized city services or should newly built communities plan
on finding their own utilities?
• How functional is sub-national governance from municipal or public agencies?
• Are Haitians looking to move into their old neighborhoods, into their current displaced person
camps, or into new housing facilities?
• What kinds of emergency/temporary housing are being created at present?
• What are the systems of coordination between government, aid agencies, and local leaders in
relocating and/or building housing?
INFRASTRUCTURE + LAYOUT
• What are the necessary utility lines?
• Which facilities can be shared, and which should be private?
