25. IN 2007, Atlanta faced the second driest year
on record

18.5 inch rainfall
deficit
Atlanta received 31.5 inches of rainfall
Average yearly rainfall is 50 inches

26. Beneath our Feet – Atlanta’s first Underworld

27. 1880s Construction of Atlanta’s first sewer system initiated by
walling over existing streams – a combined sanitary and
storm sewer is designed with cost cited as a major factor
CITY IN THE FOREST
By 1895 58 miles of sanitary and
combined sewers exist in an area
roughly 10 square miles
1908 1958 2008

28. 1995
Atlanta’s neglected sewer infrastructure, is at the center of
several lawsuits filed against the City of Atlanta for failing to
meet clean water standards

1908 1958 2008

29. 1998
The City of Atlanta signs a Federal Consent Decree,
committing the City to an accelerated program of activities
designed to improve water quality in metro Atlanta streams
and the Chattahoochee and South Rivers. Overall
improvements to the Cities underground infrastructure are
CITY IN THE FOREST
estimated to cost 3.9 BILLION dollars
1908 1958 2008

30. 2007
Combined Sewer Overflow (CSO) Tunnels, are under
construction or completed in two primary watersheds to
alleviate storm water quality issues during rain events.
CITY IN THE FOREST
Over 2,000 miles of sanitary and
combined sewers exist in an area
roughly 19 square miles

34. Increasing tree cover from 29%
(current) to 40% in Atlanta would

have the following effect:
Stormwater runoff reduction of 20% at
a value of $1.7 billion

metro)

41. 2108
Atlanta is the first
CITY IN THE FOREST
restorative city.
Nature is the model
for city form and
infrastructure. The
City lives on the rain
that falls on its land.
All its energy is from
the sun and wind. A
web of transit
connects all people.
Life is in balance.

42. WATER SENSITIVE CITY
DR. TONY WONG

43. A WATER SENSITIVE CITY
1. Building flexibility & adaptability in water sources
» “Cities as water supply catchments”
2. Improving water quality and ecosystem health of
urban aquatic environment
3. Building social and institutional capital (ie.
community receptivity, professional capacity,
creating a smart community)

62. UK: ZERO CARBON DEVELOPMENT BY 2016
UK POLICY AND PLANNING REGULATION

63. PLANNING AND CLIMATE CHANGE:
SUPPLEMENT TO PLANNING POLICY STATEMENT 1
“provide a framework … to focus substantial
new development …where energy can be gained
from decentralized energy supply systems,
or where there is clear potential …;”

64. PLANNING AND CLIMATE CHANGE:
SUPPLEMENT TO PLANNING POLICY STATEMENT 1
…utilizing existing decentralised and renewable low-
carbon energy supply systems
… supply proposed and existing development
… co-locating potential heat customers and heat
suppliers
…expect proposed development to connect to an
identified system, or be designed to be able to
connect in future
…set specific requirements to facilitate connection

66. ECO TOWNS
Ten small new towns of 5,000 – 20,000
homes
To achieve zero carbon development and
more sustainable living
30-50% affordable housing, mix of uses
including schools, retail, business and
leisure
Public transit, cycling and pedestrian links
5 to be built by 2016, the rest by 2020
