FLOOD RESILIENT DESIGN
RAIN GARDENS Creating bio-swales to temporarily hold flood water, filter and act as a buffer.
IS IT ETHICAL TO BUILD ON FLOOD-PRONE AREAS AND PUT PEOPLE AT RISK DURING A NATURAL DISASTER? AND IF WE DO,
WHY DO WE DESIGN THE BUILDINGS AS WE WOULD OUTSIDE OF FLOOD-PRONE AREAS? IS IT ETHICAL THAT WE LET THE BUILT ENVIRONMENT IMPEDE ON OUR HYDROLOGICAL CYCLE, WHICH CONSEQUENTLY INDUCE NATURAL DISASTERS? SHOULD WE INVEST ON AN URBAN FABRIC THAT IS ESSENTIALLY INEFFECTIVE DURING A NATURAL DISASTER? WHAT ABOUT MAINTENANCE? COST OF DAMAGES?
INEFFECTIVE INFRASTRUCTURE An urban fabric not suited to withstand flooding requires expensive and timely repairs. This has numerous economic and social implications such as trans por t, i nf rastr u ctures an d accessibility.
DAMAGE TO OUR URBAN FABRIC AND GREEN SPACES
MISSION STATEMENT: FROM RESTORING (CURRENT) TO RETAINING (EFFICIENT APPROACH) TO SUPPORTING (HOLISTIC APPROACH) THE NATURAL HYDROLOGICAL CYCLE (RAIN & FLOODING), AS AN ETHICAL, ALTHOUGH MAY SEEM RADICAL, RESPONSE TO THE PREVENTION OF ‘NATURAL DISASTER’ FROM FLOODING, WHICH IS FUNDAMENTALLY CAUSED BY OUR CURRENT URBAN DESIGN AND FABRIC. SUBSEQUENTLY, IT SHOULD ALSO AIM TO EXPAND THE NATURAL BIO-REGION AND ALLOW ECOSYSTEMS TO THRIVE. IT SHOULD PREVENT GREAT AND TIMELY DAMAGE TO THE BUILT ENVIRONMENT AND HUMAN SUFFERING DURING FLOODING. IT SHOULD ALLOW NATURE TO FREELY PASS IN AND OUT OF A SYSTEM, WITHOUT CREATING HARM TO ANY LIVING ENTITIES, AND REINFORCE AN OPEN-LOOP SYSTEM WHICH EMBRACES AND EDUCATES ON THE COMPLEXITY OF TRUE SUSTAINABILITY. IT SHOULD CREATE A FUTURE OF...
INACCESSIBLITY PERMEABLE FABRIC AND INFRASTRUCTURE Absorb water back to native soils through integrated vegetation and pervious surfaces, as replacement to asphalt concrete which increases stormwater run-off and inland flooding.
Failure and inability of Emergency Services to fully function during flood times.
PERMEABILITY, BUFFERING & RE-GREENING ...IN URBAN CITIES
CARYL QUEJA | 06782132 URBAN ENVIRONMENT Turn the city into a “permeable city” through pervious surfaces and re-greening areas, to support hydrological cycle and prevent crisis occurring from ‘natural flooding’. This will then prevent ‘inland flooding’, as water is absorbed by the soil, then back to the river.
GREEN BUFFER
RIPARIAN EDGE
Preserve green spaces and restore natural vegetation. Integrate to public spaces, bikeways, etc. Be suited for public activities as well as flexible private commerce.
Retain natural features and allow for ecosystems to thrive. Improve soil and provide wildlife habitats.
Assist with tidal flooding, from damaging urban fabric and infrastructure. Filters water running off to the river.
KEY INTERESTS & RELATIONSHIPS ON FLOOD RESILIENT DESIGN: “PERMEABILITY, BUFFERING & RE-GREENING
OBJECTIVES STRATEGIES BRISBANE RIVER Retain and restore Brisbane River by preventing waste from entering the river system.
ECONOMY: INTEGRATED WATER RECYCLING INITIATIVES BOTH PRIVATE AND PUBLIC SECTOR TO BENEFIT FROM PROPOSED ‘BUFFER ZONES’ AS PLACES FOR ACTIVITY AND/OR COMMERCE. CONSTRUCTION OF PARKS FINANCED BY MEANS OF ACTIVITIES IN THE PARKS SUCH AS RESTAURANTS, ENTERTAINMENT, WORKSHOPS, ETC. RELOCATE INFRASTRUCTURE INCLUDING TRAFFIC ROADS AWAY FROM RIVER, LOCATE PEDESTRIAN AND BICYCLE PATHS NEAR THE RIVER. RELOCATE MAJOR SERVICES AND AMENITIES AWAY FROM INLAND AND TIDAL FLOODING BY LOOKING AT A LOCAL “FLOOD FLAG MAP” TO PREVENT DAMAGE AND INCREASE EFFECTIVENESS OF EMERGENCY SERVICES. ENGAGE WITH DESIGNERS AND PERMEABLE TECHNOLOGY. INVEST ON MATERIALS AND TECHNOLOGY THAT WORK WITH THE FLOOD
ENVIRONMENTAL: ENVIRONMENT LEGISLATION THAT PROTECTS LOCAL VEGETATION AND NATURAL SYSTEMS. IMPLEMENTATION OF RAIN GARDENS AND BIO-SWALES EXTENSIVELY IN THE URBAN LANDSCAPE TO COUNTER INLAND FLOODING. INVEST IN NON-TOXIC, PERMEABLE AND DURABLE MATERIALS. RESTORE WILDLIFE HABITAT BY PROTECTING RIPARIAN EDGE. COMMUNITY CLEANING - OF BIO-SWALES,ETC - TO FILTER WATER; & COMMUNITY MAINTENANCE OF NATIVE VEGETATION. GOVERNMENT: FINANCIAL INCENTIVES TO ENGAGE PRIVATE COMMERCE; TAX RELIEF IF DEVELOPMENT INCLUDES GREEN AREAS. IMPLEMENT “TRANSFER OF DEVELOPMENT RIGHTS” TO INCREASE GREEN SPACES. COMMUNITY-FOCUSED PLANNING INITIATIVES, INVOLVING EVERYONE. ENFORCE A COMPETENT BUILDING PRACTICE/ INSPECTION TO ENSURE ALL BUILDINGS ARE STRONG ENOUGH TO WITHSTAND FLOODS. ZONING LAWS
COMPACT SETTLEMENT Still operable during and after flood crisis.
RELOCATE BUILDINGS AND INFRASTRUCTURE Relocate away from riparian edge, floodplains and lowlying areas to prevent damage from floods and economic downfalls.
PEDESTRIAN PATHS & BIKEWAYS Encourage walkability and activity in urban environment. Opportunity to share space and support social and cultural interaction.
MEASUREMENTS FOR SUCCESS... MEASURE AFFECTED AREAS AGAINST FLOOD FLAG MAPS. AMOUNT AND FREQUENCY OF PUBLIC ACTIVITY (SOCIAL INTERACTION) SAVINGS IN REPAIR AND DAMAGE AIR QUALITY & CLEANLINESS AREA OF OPEN SPACE PER PERSON WATER SAVINGS
BIKEWAYS AND PEDESTRIAN PATHS TO ENCOURAGE WALKABILITY
Green spaces may be submerged temporarily. Opportunity for floating flexible spaces during flooding. However, the landscape would allow a fast recovery and no damage would be inflected on infrastructure and buildings.

BUILDING INTEGRATED WATER RECYCLING INITIATIVES
If designers, planners & local community is educated on flood flag maps to illustrate flood-prone areas and spread understanding of buffer zones.
To protect areas near the river from development and to create more green spaces, landowners can exchange development rights for height increases elsewhere.
Building integrated systems which reduce the cause of inland flooding and stormwater run-off, which also functions as water recycling system.

Act as filter and prevents waste and toxic materials from getting into the river.
This can also be used as a reference, when measuring decrease of floodaffected areas.
Investing in materials and design strategies which effectively work with flooding, and require less maintenance.
