2 ROTTERDAM

3 Rotterdam City Area : 320 km2 Population: Nationalities: Municipal Budget: 4,2 billion Euros Sewer system: 3000 km 2014 Port Area: Length of port area: Direct employment: Goods throughput: Shipping: 105 km2 (50 km2 commercial sites) 40 km over 70,000 jobs over 400 million tonnes of goods per annum 33,000 sea-going + 110,000 inland vessels/yr Maeslantkering: Storm Surge Barrier

4 GEOGRAPHY: HEIGHT MAP

5 water: urban quality

6 CURRENT IMPACT EXTREME WEATHER Flooding Noordereiland Excessive rain fall Collapsing levee (drought) Heat waves

7 EXTREME WEATHER EVENTS: UHI Source: TU Delft, 2014

8 CC related challenges Possible consequences of flooding: Inner dike and outer dike Increasing number of problem locations concerning: Storm water, salination and drought, heat island effect

9 STRATEGY

10 RAS: OBJECTIVES Protection from river and sea Minimal disruption from too much or too little rainfall Accessible and safe port Community awareness CCA leads to a more attractive city CCA strengthens economy

11 Strategy Big & Small Grey & Green Protect & Embrace Maximise piggybacking to reduce costs and nuisance v

12 Perspectives

15 COMPACT CITY

16 Societal Cost-benefit analysis showed: MONETIZING THE BENEFITS Measures with positive outcome Benefits for different parties Benefits take time: LT thinking Piggybacking is cheaper!

17 Actions

18 MULTIFUNCTIONAL SOLUTIONS

19 WATER STORAGE: PARKING GARAGE

20 WATER SQUARE BENTHEMPLEIN Water square Benthemplein, just after a good shower

21 TEMPORARY STORM WATER STORAGE

22 COMMUNITY INVOLVEMENT: GREEN ROOFS

23 ADAPTIVE BUILDINGS

24 Nature, Recreation and Water Safety

25 The River as a Tidal Park

26 Mainstreaming

27 From stand-alone to standard procedure Examples: Heat procedure for prioritised bridges Heat and drought in tree policy Elevation standards (uitgiftepeilen) Permeable pavement Rotterdam Standard v

28 Analysis of municipal instruments Programmes, plans & procedures: Operation & Maintenance (e.g. sewerage) Greening programmes Private investments (negotiations) Municipal plans (e.g. masterplans, zoning plans) Regulations (e.g. building permits?) Conditions: standard designs ( moederbestek ). >> focus on municipal activities: large area + big influence = high impact v

29 Monitoring

30 MONITORING OBJECTIVES Report progress to council and citizens: Accountability (time and ) Communication > awareness & support Learn and improve adaptation efforts

31 MONITORING: 5 dimensions - Risks (probability*consequence) - Targets (how much is enough?) - Effort (how many m2/m3 etc added?) - Effect (of implemented measures) - Speed (are we going fast enough?) New developments & knowledge lead to new risks/targets/effects and might require adjustments in speed.

32 Kortom: Samenwerking is de sleutel in alle stappen van het proces Inzicht in huidige impacts >> draagvlak Geen-spijtmaatregelen> leren & inspireren Toekomstige risico s > slimme beslissingen Identificeer win-win maatregelen Borging bij alle partijen Monitor voortgang v
