STATEMENT OF FACTS

1) Climate change is real, and the impacts of climate change, including rising temperatures, more frequent and
powerful storms and rapid sea level rise are increasing quickly, and these impacts present a significant threat, both
globally and locally across our entire City

2) Part 2 of the recently released Cambridge Climate Change Vulnerability Assessment clearly states that “the
Alewife-Fresh Pond area is at greatest risk of storm surge flooding by 2070” and, further, that future “storm surge
flooding, particularly in the Alewife-Fresh Pond area, will pose risks to populations, buildings, and infrastructure;”

3)  $5.6 billion worth of property, and 94.6% of all new Alewife residential units built since 2004, are located
within the FEMA 100-year or 500-year floodplains

4)  In 2005, 67% of Cambridge’s land area was made up of impervious surfaces, and due to heat island effects,
completely impervious surfaces are up to 14.4 degrees Fahrenheit (8 degrees Celsius) hotter than completely permeable surfaces

5)  Onsite capture and containment of stormwater in green infrastructure is preferable to the rapid and
unmanaged discharge of stormwater to nearby water bodies via concrete tanks and pipes

6) Adequate permeable open space has been proven to increase flood storage capacity, moderate stormwater
discharges, enhance groundwater replenishment, improve overall water quality, allow room for mature trees, and
provide important social and community benefits

7)  Increased tree canopy coverage provides reduced heat effects, lowers energy costs associated with cooling,
enhances air quality, sequesters carbon, improves mental health and quality of life, reduces roadway maintenance
costs, and aids significantly in stormwater capture and dispersal

8)  An adequate understanding of past and present soil & water contamination and of current hydrological conditions is essential to public health when developing areas built on top of filled wetlands

9)  Reduced parking ratios may encourage transit-oriented development, reduce housing construction costs, and
increase the amount of land available for open space

10) Adequate site and building access is essential at all times, but especially during severe storms and other times
of emergency.

11)  It is imperative that adequate backup systems exist to protect the safety of residents and workers during times
of emergency, and that mechanical equipment and utilities are protected from damage by stormwater

12) Ground floor spaces should not include residential uses, in order to better ensure protection from present and
future flood waters

13)  Appropriate emergency preparedness planning is considered a High Priority recommendation by the Envision
Cambridge planning team and life-supporting Critical Facilities require specialized resiliency planning to ensure the
continued operation of and access to such facilities during times of need

14) The City has a moral and financial interest in ensuring that buildings built today remain safe and maintain their
value for generations to come, and that to continue to offer quality services the City must protect its tax base in both
the short and the long term.
