CCPR The Port Plan Issued & Public Meeting - June 11
A new neighborhood Climate Change Preparedness and Resilience Plan for The Port has been issued. A public meeting will be held on Tuesday, June 11, 6:00-8:00 pm at the Community Arts Center gym, 119 Windsor Street. The public meeting will involve an open house to present features of the plan and information on how residents and businesses can make themselves more climate resilient. A panel discussion will be held during the second half of the meeting. The meeting will have translators for speakers of Spanish, Haitian Creole, and Portuguese; free childcare; and food and drink.
The Plan is available online. it consists of the main report, an appendix on gray and green infrastructure, and an appendix on energy resiliency.

Comments on The Port Plan can be submitted to John Bolduc, email@example.com or in writing to John at Community Development Department, 344 Broadway, Cambridge, MA 02139. Comments will be used to inform the Citywide Plan. Please submit comments by June 30th.
- The City has issued The Port Preparedness Plan for comment. Together with the Alewife Preparedness Plan, the two neighborhood plans will inform the citywide plan that is to be completed by the end of 2019. A public meeting on The Port Preparedness Plan will be held June 11, 6:00-8:00 pm at the Community Arts Center gym, 119 Windsor Street. Comments on the plan should be submitted by June 30 to John Bolduc, firstname.lastname@example.org or in writing to John Bolduc, Community Development Department, 344 Broadway, Cambridge, MA 02139. Citywide CCPR Plan will begin development in the summer of 2019. To receive notices of public meetings, contact John Bolduc at email@example.com or 617-349-4628.
The City Manager directed City departments to prepare a Climate Change Vulnerability Assessment (CCVA) and preparedness and resilience (CCPR) plan based on a recommendation from the City's Climate Protection Action Committee. The CCVA has been completed and work has begun on the CCPR Plan.
The vulnerability assessment is largely a technical study of Cambridge's physical and social vulnerabilities to increasing temperatures, more intense storms, and storm surge flooding associated with sea level rise. The CCVA serves as the technical foundation for the CCPR Plan. The CCVA consists of two summary reports -- Part 1 on risks from increasing temperatures and precipitation and Part 2 on risks from rising sea levels and coastal storm surges. The summary reports are backed up by technical appendices covering climate projections, modeling of flood risks and urban heat islands, economic and public health assessments, and detailed vulnerability ratings and rankings for physical assets and neighborhoods. Priority planning areas and issues are identified.
The CCPR Plan will recommend strategies to increase the city's level of preparedness and resilience to more intense and longer heat waves, higher average temperatures, changes in precipitation patterns and intensity, and risks from rising sea levels and storm surges from coastal storms. The strategies will cover parcel, neighborhood, citywide, and regional scales. The CCPR Plan is paralleling the Envision Cambridge Plan by focusing first on the Alewife area of the city, where there is relatively more flood risk, particularly from future sea level rise and storm surges. A second neighborhood plan will be developed for The Port and then the work will be rolled up into a citywide plan.

While the City develops the Climate Change Preparedness & Resilience (CCPR) Plan, we are engaged in various activities to advance the city's level or preparedness in the meantime. These activities include:
Metro Mayors Climate Change Preparedness Task Force
- Cambridge is part of the group of 15 metro Boston cities that have committed to work together to prepare the region for climate change.
Cambridge Flood Viewer
- The Flood Viewer is a tool to look up flood elevations, ground elevations, and flood extent based on FEMA flood insurance zones and the Cambridge Climate Change Vulnerability Assessment.
Urban Forest Canopy Assessment Update
- The City worked with the University of Vermont Spatial Analysis Lab in 2012 to measure Cambridge's urban forest canopy using 2009 data and assess it's distribution and potential for expansion. The urban forest canopy assessment was updated in 2017. Another update is planned for 2018 after new data is collected.
Flooding: Is Your Property Protected
- The Public Works Department produced an information guide for Cambridge residents on how to protect homes from flooding.
Cambridge Compact for a Sustainable Future
- The sustainability compact is an initiative launched by the City, MIT, and Harvard in 2014 to foster collaboration among Cambridge's institutions, businesses, and government to advance sustainability in the city. One focus of the compact is on climate change preparedness.
DOER Community Clean Energy Resiliency Initiative
- The Cambridge Water Department was awarded a grant of $851,868 to assess the feasibility and plan implementation of islandable energy storage at the Sullivan Water Treatment Plant. If feasible, the project would involve installation of battery storage, fed by the plant's 170 kilowatt solar photovoltaic system, and switching equipment to be installed so that a portion of the faclity could be operated during an outage of the electric grid.
Urban Forest Master Plan
- The Public Works Department is leading the development of Cambridge's first Urban Forest Master Plan, which looks at all trees on public and private property as a system, The plan will establish goals and strategies to maintain and expand the urban forest to provide a range of environmental and public services, including reduction of urban heat islands and cooler and safer outdoor environments.
Municipal Vulnerability Preparedness Action Grant
- Cambridge has been designed an MVP community under the Commonwealth of Massachuetts's new Municipal Vulnerability Preparedness (MVP) program. This means the Commonwealth recognizes that the City has completed a vulnerability assessment and makes the City eligible for action grants. Cambridge was awarded $118,000 in the first round of grants issued in May 2018. The grant will be used to evaluate the CRLS-War Memorial-Public Library complex for its role as an emergency community shelter and possible ways to make it more robust and resilient; work with community organizations to develop business plans for two "resilience hubs"; and develop toolkits and workshops on climate change preparedness and resilience for renters, small residential properties, small businesses, and large businesses and organizations.

CCVA Part 1 – Updated Information (April 2017)
How the precipitation flood model was updated:
The model for projecting flooding from extreme precipitation has been updated to integrate manhole and riverine flooding into one model. The updated model includes flows from tributary regions of Somerville, Belmont, Arlington and Malden River, extends downstream to the Amelia Earhart Dam, and reflects the recent reconstruction of the Cradock Bridge in Medford. The updated model is more reliable in depicting flooding risks. The updated model developed using ICM-2D integrates the previous Mystic River basin FEMA HEC-RAS riverine hydraulic model with the City of Cambridge combined sewer model in the Alewife Brook watershed. This allows for more dynamic interaction between riverine flood levels and the piped infrastructure’s response to it, which results in more realistic and accurate representation of actual flooding conditions. Also, since the updated model is calibrated to available river stage and flow data at multiple locations in the Mystic River watershed, it is expected that this model will better simulate the flows and flooding in Cambridge for future precipitation scenarios.
Updated priority areas for precipitation flooding & revised key findings:
The updated precipitation flooding maps for the 100 yr. and 10 yr. storms for 2030 and 2070 do not show significant difference in the extent of flooding to the exception of small larger areas around Fresh Pond where few items have been added as at risk for flooding or removed. More significant changes are reported in the depth of flooding with less depth of flooding. Key findings remain the same as the Alewife Area remains one of the most vulnerable area to flooding for the City of Cambridge as early as 2030.
