1. SESSION: CLIMATE CHANGE ADAPTATIONS Climate Change Vulnerability Assessment Project: New Level of Infrastructure Planning, City of Cambridge, MA Rich Niles., Senior Project Manager, AMEC AMEC is one of the technical leads for the Climate Change Vulnerability Assessment for the City of Cambridge, Massachusetts as a subcontractor to Kleinfelder, Inc. The City of Cambridge has been working for over two decades to address a variety of environmental issues and has recognized climate change as an increasing concern requiring attention. The City wishes to evaluate and prepare to adapt to a variety of climate change phenomena that may affect the welfare of the City and its infrastructure. This presentation will discuss the scope of work to evaluate potential climate change related impacts to the City of Cambridge. This includes a screening and prioritization of critical infrastructure based on existing known problems, available data and key characteristics that are unique to the City of Cambridge (e.g., surface water supply, tidal waterfront). The Project Team and stakeholders have begun to identify and rank vulnerabilities for further evaluation in conjunction with on-going efforts by others, such as the Massachusetts Department of Transportation (MassDOT). For example, the MassDOT is conducting a vulnerability assessment of the Central Artery tunnels to flooding and the City of Cambridge intends to expand upon the results of this modeling effort and enhance its vulnerability assessment with respect to storm surge, sea level rise and localized flooding. This presentation will highlight the newest challenge that cities face to begin evaluating climate change impacts. Once the vulnerability assessment is complete, the City of Cambridge anticipates developing a climate change preparedness plan. Rich Niles is a Senior Project Manager with AMEC Environment & Infrastructure, Inc. and a key lead for Water Resource Services in the Northeast U.S. and the firm’s international Climate Change Practice. Rich has been assisting communities for the last 14 years to develop and implement a variety of water resource and infrastructure management programs. His projects encompass a wide range of expertise from stormwater management and finance programs to stream restoration, flood mitigation and levee assessment. Rich is well suited in the management of complex multi-disciplinary projects that often involve working with stakeholder groups in multiple jurisdictions. Nathalie Beauvais has more than 20 years of experience in the fields of architecture, urban design and planning with a strong emphasis on sustainability, climate change and the integration of planning and engineering expertise. She is a senior member of Kleinfelder’s sustainability practice where she currently manages the team of scientists, academics and sustainability experts conducting the City of Cambridge Climate Change Vulnerability Assessment and Adaptation Plan and the Massport Disaster Infrastructure and Resiliency Planning Study. She is an author and speaker on comprehensive planning, sustainable planning and climate change. Ms. Beauvais teaches at Wentworth Institute of Technology in the Master Program for Architecture.
