Advancements Mapping and Dam Safety 1. INTRODUCTION The Calgary Flood (2013), Manitoba Flood (2011), and City of Toronto Urban Flooding (2013) resulted in large insurance claims and public sector costs. Studies were commissioned by the insurance bureau of Canada and by private insurance companies following these floods. Besides insurance company claims, government costs and claims for disaster assistance related to flooding have all been increasing over the past decade. The following quote from Public Safety Canada accompanied the release of the recent National Floodplain Mapping Assessment report in June 2014. "Canada has witnessed a notable increase in flooding over the past decade, with total damages exceeding $10 billion. As part of Public Safety Canada's mandate to mitigate losses resulting from natural events, a National Floodplain Management Framework was prepared by MMM Group as an initial step in reducing flood risk across Canada." (Public Safety Canada 2014) The increased private sector and public sector costs related to floods coupled with media attention all combined to result in a renewed interest in understanding floods, how effects of flooding could be mitigated, and how 12 increasing disaster recovery costs could be contained. In response to increasing disaster recovery costs and interest from the insurance industry regarding flood insurance, the Federal government commissioned a National Floodplain Mapping Assessment in the late fall of 2013. The final assessment report was completed in June 2014. The National Disaster Mitigation Program (NDMP) was announced in January 2015 and launched in April 2015. The NDMP funds flood risk assessments, floodplain mapping updates, flood mitigation assessment. and small flood mitigation projects. In anticipation of the NDMP, the Ontario Ministry of Natural Resources and Forestry funded a series of case studies to investigate new approaches and available technology that can aid in the creation of the next generation of floodplain mapping. This article provides an overview of these case studies, the recent National Floodplain Mapping Assessment, and the National Disaster Mitigation Program (NDMP). Throughout the article, new floodplain mapping initiatives are linked to dam safety and why the dam safety community needs to be aware of current initiatives. 2. PUBLIC SAFETY CANADA NATIONAL FLOODPLAIN MAPPING ASSESSMENT 2.1 Flood Damage Reduction Program (FDRP) 1975-1995 The last floodplain mapping program was the federal Flood Damage Reduction Program (FDRP) program which ran for twenty years from 1975 to 1995. This program was in response to escalating disaster assistance payments related to flood damages in the early 1970's. The objective of the program was to map flood risk areas, to identify cost-effective flood mitigation options for vulnerable areas, and to provide base mapping to allow incorporation of floodplain policies into municipal planning documents, a condition of program funding at the time. This program preceded modern day Geographic Information Systems (GIS). Mapping produced as part of the FDRP program used conventional photogrammetry, resulting in hardcopy non-digital base maps as the issued product. Some digital base mapping was produced towards the end of the program; however, digital standards were not well established and have evolved dramatically since that time. Creation of this mapping relied on very View past issues of the CDA Bulletin online at www.naylornetwork.com/cda-NXT/ http://www.naylornetwork.com/cda-NXT/
