On 2 July, 2011 large areas of the city of Copenhagen were flooded in a cloudburst. The Copenhagen Climate Adaptation plan was adopted in 2011 in response to the extreme, water-related consequences of climate change to which the city is exposed. In a city where many buildings and services are located below street level and where stormwater and sewage are in a combined pipe system, contaminated floodwater penetrated buildings and city infrastructure. Crisscrossed by a number of constructed urban barriers (such as streets, sidewalks, buildings, or train tracks) and with only minimal grade differences that prevent floodwaters from positively draining towards the main Copenhagen harbor outlet point into the sea, the key difference between the two options is the strategy for mitigating Sankt Jørgens Lake. Climate changes will inevitably transform the urban landscape. Climate adaptation Denmark cloudburst plan Copenhagen livable cities project The Rainflower is a sustainable multifunctional rainwater collector. The City of Copenhagen and Greater Copenhagen Utilities (HOFOR) assisted by Cowi have developed a general and citywide cloudburst masterplan that divides Copenhagen and Frederiksberg into catchments to found the basis for the specific master planning and project identification.

The Blue-Green Approach develops a synergistic relationship between the two, integrating climate adaptation solutions within the limited confines of urban space, encouraging a solution utilizing the best of both techniques. The city administration has furthermore included HOFOR, the regional water company, and inv… Design and Qualify:  Hotspots were identified, transferring strategic planning to human-scale experiences as a model for how other cities can mitigate Cloudbursts and daily rain events. A recent interactive workshop led by the Engineer and Landscape Architect in a suburb of Copenhagen engaged residents through a series of interactive sessions designed to raise awareness and survey desired citizen interests. 542. “The cloudburst was really a wakeup call. important plans, such as the Climate Action Plan, the Bicycle Strategy and the Strategy for Urban Life. The City of Copenhagen developed a Cloudburst Management Plan in 2012, to combat the impacts of cloud bursts. The strategic flood masterplan is the opportunity to safeguard Copenhagen while providing the foundations for a high-quality city environment. Adapting to climate change does not come cheap. Involvement and Iteration: Cloudbursts would influence each area of Copenhagen; an overall strategy for a public participation program was established to gauge the requirements of the citizens who would be affected. The plan was prepared under the administration of Mayor for technical and environmental affairs, Morten Kabell. The old working-class neighbourhood of San Kjeld near to the city’s port will be the first climate-change-adapted urban area in the world. The solutions are based on real situations, aligned to preexisting underground infrastructure.

Heavy rainfall in July 2011 prompted the city to develop a specific Cloudburst Management Plan in 2012 . The lake overflows into a 2.5m diameter tunnel to the harbor as a reduced sized pipe. In July 2011, in less than two hours, Copenhagen was hit by an extreme 1000-year storm event – or Cloudburst – where 150mm of rain left large areas of the city under up to one meter of water. Copenhagen realized that Cloudbursts were not a one-off occurrence; the threat compounds as harbor sea levels are predicted to rise one meter by 2110. René Sommer Lindsay, the city official in charge of St. Kjeld’s transformation. Cloudburst master plan The municipality of Copenhagen decided to implement a cloudburst master plan for the protection of the city against future cloudbursts. The listed park has been transformed into a climate project with a 22.600 m3 water reservoir. Cloudburst solutions are often left out of upstream area planning where residents see no flooding problems. plan will be fully implemented throughout the city by around 2033. by the middle of this century, copenhagen will have smaller streets surrounded by plenty of trees and shrubs designed to absorb runoff and regulate water flow, while channeling excess water from storms into cloudburst boulevards. Copenhagen is on the front line of climate change, experiencing increasingly heavy rain events, as they are also on the leading edge of urban innovation with a vision of transforming their city into a sustainable, C02 neutral city by 2025. CLOUDBURST MANAGEMENT PLAN OF COPENHAGEN Cloudburst is defined as a heavy rainfall with more than 15 mm of rain falling in 30 minutes (Website 2, dingeo). The implementable, pragmatic tools mitigate extreme storm events and improve our cityscapes. Additional qualitative social benefits, such as health, environmental, and urban spatial quality improvements resulting from the enhancements would potentially push this number even higher. Two masterplan variations were developed to assess potential advantages and disadvantages – Option 1 Conventional and Option 2 Blue-Green. Copenhagen has experienced major rainfall events in the past years. The plan puts Copenhagen on track to becoming the world’s first car-bon-neutral city by 2025, and since launching its first Climate Plan in 2009, the city has already achieved significant reductions in … These plans are based on an un-paralleled city-wide use of integrated planning and implementation of blue-green infrastructure, that have inspired planners on an international basis. Copenhagen’s adaptation plan finds that the risk of serious damage to the city from rising seas will begin to change significantly in about 30 years. The Plan is based on the Copenhagen Climate Adaptation Plan and on detailed flood mapping and risk analyses. Splitting the bill between water utilities and the city budget made financing Copenhagen’s cloudburst plan possible. The process was formalized as the Copenhagen Cloudburst Formula, a six-step procedure for integrating the Blue-Green Approach: Demonstrating the relevance of the Cloudburst Toolkit palette of retrofit techniques on the first selected Hot Spot of the 10 km2 catchment of Lådegåds-Åen (a priority catchment set in the center of Copenhagen and at a high risk to flooding) investment opportunities in the form of Blue-Green techniques were created on the surface where they are visible, interactive urban components. Conventional infrastructure is considered to be generally technical, underground, hidden elements while Blue-Green solutions are low-tech, on the surface, and interactive. PUBLIC-PRIVATE ENGAGEMENT – LASTING BENEFITS: Concerning the climate adaptation plans in regard to the Three Points Approach (3PA), Copenhagen has determined the required framework for adaptation of the inner parts of the city with regard to extreme rainfalls (Cloudburst Management Plan in Copenhagen) while The option with the highest percentage of Blue-Green solutions and also the least additional infrastructural pipe improvements created a potential savings 50% greater than Conventional solutions alone. © Oppla 2020 ● Privacy Policy ● Terms of Use, City of Copenhagen, City of Fredriksberg, HOFOR, The City of Copenhagen Cloudburst ManageMent Plan 2012, Landezine article: Copenhagen Strategic Flood Masterplan, Klimakvarter, Copenhagen Climate Resilient Neighbourhood, Copenhagen, 2016, Klimakvarter, Environmental Administration - The Integrated Urban Renewal in Skt. Copenhagen’s First Climate resilient neighbourhood Green streets, green urban squares, and cloudburst streets that diverts rainwater away from the neighbourhood, these are ways in which we can avoid water damages when extreme rainfall events or cloudbursts occur. The Copenhagen Cloudburst Management Plan 2012 is a blue-green stormwater management infrastructure, where rainwater is led to open spaces and other buffer areas during rain events until the drainage system has recovered its capacities and can take in that extra water. Acting with visionary foresight, the municipality of Copenhagen has decided upon a comprehensive Cloudburst Management Plan for the entire city, including 300 cloudburst adaptation projects in the next 10 to 20 years. Putting the Cloudburst Management Plan into action will take a long The Cloudburst Management Plan will form the basis for the implementation of mitigation efforts in the city and will also form part of general City Administration planning. The Copenhagen 1948 Finger Plan | Urban design graphics, Urban design concept, Urban spaces design For 4 of the initial specific catchments Ramboll and Studio Dreiseitl - in cooperation with the City of Copenhagen, Greater Copenhagen Utilities (HOFOR), Frederiksberg Municipality and Frederiksberg Utilities - proposed a vision and concepts that became boiled down into 3 masterplans covering more than half of the more than 300 projects in the two cities; Copenhagen and Frederiksberg. The University of Copenhagen offers a wide range of Master's degree programmes (MA/MSc) taught in English. Comprehensive site analysis led to establishing the Copenhagen Cloudburst Formula and a Cloudburst Toolkit of urban mitigation strategies and components. In contrast, the Blue-Green Masterplan Option lowered the lake level from +5.8m to +2.8m, creating a new Cloudburst storage volume of 40,000m3 and a revitalized lakeside connection which had previously been only partially accessible. Copenhagen_Cloudburst-Masterplan-Atelier-Dreiseitl-04 « Landscape Architecture Platform. The plan was designed in collaboration with the consultancy COWI, and in 2013 it won the international acclaimed design award, Index:Award (INternational DEsign eXhibition). In 2011 ,Copenhagen experienced the worst and most destructive cloudburst in the city’s history. Cities around the world can look to the Copenhagen Cloudburst Formula as a model for implementing innovative, pragmatic, feasible measures within existing urban fabric. Private developers and homeowners alike become champions for local solutions where a multi-disciplinary, cross-agency collaboration engaged designers, planners, sociologists, economists, biologists, geographers, information specialists, and communication experts interacting with public utility companies, stakeholders, interest groups, local politicians, and investors. tions are to be applied in Copenhagen in the coming years. The park is one of 300 cloudburst projects that the City of Copenhagen and Greater Copenhagen Utility (HOFOR) plan to finish in the next 20 years to protect Copenhagen against future flooding. The Ladegads-Aen catchment was selected as a prototypical test area due to its high risk to flooding and sea surges. A common vision aligned engineers, hydraulic experts, GIS and information technologists, architects, planners, biologists, economists, communication specialists, and landscape architects with local citizens, investors and politicians. The “Cloudburst Management Plan” addresses 8 central city catchments (Norrebro, Ladegards-aen and Vesterbro, Valby & Vanlose), encompassing a total area of 34 km². Download the NYC Cloudburst Resiliency Study; Download the City of Copenhagen Cloudburst Management Plan 2012; As a result of the cloudburst study, we’re now testing the implementation of cloudburst infrastructure at the NYC Housing Authority’s South Jamaica Houses. The technical engineering investment is calculated at twice the size and cost of the pipes required for the Blue-Green Option, and also creates limited new public green space. The Adaptation and Cloudburst Plans and accompanying measures aim to establish the co-sharing of adaptation between the City of Copenhagen, citizens and other private actors. Copenhagen has found a way to co-finance its flood protection plan, provide for new civic amenities, dig up fewer streets and save money, all thanks to one tweak of the law. The insurance damage savings and the increase in real estate value are two of the highest socio-economic benefits from Cloudburst adaptation.
