assessment relies on climate (current and future) data, the performance of theinfrastructure in future years is equally important in establishing risks.• There is a lack of knowledge about the infrastructure performance (structural, functionalor operational) over the life cycle of the infrastructure.• Water infrastructure CSRI usually consider the design of new assets and provide little orno guidance on existing infrastructure or on the long-term performance of rehabilitatedinfrastructure.• Vulnerability assessments, and thus the future climate projections considered, should bedone over the expected service life of the infrastructure and consider life-cycle eventssuch as major repairs and rehabilitation.4.6 Other observations• The representative scale of climate data that is often required is unavailable or difficult toachieve, thereby requiring the involvement and analysis by trained meteorologists.• There is a lack of latitude is many CSRI for the use of professional judgment to applyadaptive management principles (e.g., planning for infrastructure needed for future climateconditions by setting aside land).• Use of “adaptive management” in the design, operations and maintenance of theinfrastructure allows considering the uncertainties about future climate and infrastructureperformance. This requires:• Long-term planning• Consideration of the life-cycle of the infrastructure• Including risk management in the design, operations and maintenance• Design for impacts (structural, functional, operational)• Performance oriented CSRI (as opposed to prescriptive)• There is a need to consider more than CSRI provide or require for the design ofinfrastructure in a changing climate (e.g., risk assessments, adaptive management, etc.)5. Conclusions and RecommendationsThis report provides the analysis of 13 water related PIEVC case studies in regards to climatedata in current Canadian CSRI. The basis if the analysis was a methodology and associatedtool developed by RSI to identify the infrastructure-climate interactions with the greatestpotential for a review of related existing CSRI. It should be reiterated here that the high priorityFINAL REPORT Page 13 of 22PIEVC CSRI Water Review
CSRI review candidates were not necessarily those infrastructure-climate interactions identifiedas high risk in the PIEVC case studies.The results of the analysis using the RSI tool were discussed by the water infrastructure EWGand their observations related to the source, use and update of climate data, the types of CSRIused in the water industry, and the different climate events impacting water infrastructureperformance are summarized in the report.This review of the PIEVC case studies, the (not exhaustive) review of relevant literature, butmostly from the EWG observations and discussions were used to produce the followingrecommendations.1. Existing CSRI should clearly provide information on the assumptions and source ofclimate/weather data used.2. Weather and climate data needs to be updated on a more regular basis. The frequencyof the update will depend on the type of infrastructure (based on its service life) and thetype of climate events. CSRI writing organization should establish an appropriate reviewperiod for the weather and climate information used in the documents they produce.3. CSRI should provide guidance on the type and collection frequency of climate data andinformation required for planning, designing, operating and maintaining waterinfrastructure. For example, rainfall instruments need to measure intensity in order togenerate IDF curves. CSRI should also address the density (number of instruments in acertain area) for meaningful data collection.4. The evaluation of the risks to the infrastructure requires the evaluation, in the future, ofthe climate-infrastructure interaction. Both the projections– and uncertainties thereof, offuture climate and future infrastructure performance should be addressed in CSRI.5. CSRI should address incremental options, over the life cycle of the infrastructure, forclimate change adaptation.6. Physical, functional and operational performance considerations should be addressed inCSRI in view of future climate and infrastructure condition.7. Identifying the risks to infrastructure from future climate events requires engineering,operations, management, planning and climate/weather expertise. Strongercollaboration between these professions, possibly through CSRI, is essential.8. The design – for new construction, rehabilitation or renewal of existing infrastructure,should provide flexibility for adaptation to climate change.
