RE: BILL 178 — Clifto's Kona Coast LLC
Dear Members of the County Council,
I support Mayor Kim's VETO of the Clifto's project in O'oma, North Kona.
However, I don't support concurrency if it means more car -oriented planning and
if it means that you will continue to approve more sprawling development.
Those of you, (including past West Hawaii council members like Am Rath, ]ohn
Ray and Keola Childs) who voted FOR development along Queen Kaahumanu
Highway without forcing developers to build homes nearby for their workers, are
all responsible for causing West Hawaii to become a sprawling mess. You are
the ones who, by way of approving your sprawl -related developments, have
given us the congestion that we are faced with today.
According to the first of two articles from the Surface Transportation Policy
Project (STPP), which I Included with my testimony, studies indicate that sprawl
Is a primary cause of congestion. Sprawling development patterns such as what
we are seeing here In West Hawaii are causing people to drive further and to
drive more often.
According to the second article from STPP, building new and wider roads has
little long-term Impact on road congestion. In fact, studies indicate that new
and wider roads actually generate more traffic. This phenomenon, known as
"induced travel" occurs when drivers flock to the new facility hoping to save time
and people who would otherwise avoid congested conditions or take alternative
modes to their destinations are likewise drawn to the new roadway. In the long
run, the new roadway encourages new development nearby which leads to more
traffic.
So building more roads in order to keep up with your sprawl -related
development approvals Is not going to correct West Hawaii's congestion
problems. It will just make things uglier and soon well be looking like Honolulu.
If you folks sincerely want to correct the wrongs that you have done to West
Hawaii, you need to support the Mayor's VETO, stop approving any sprawl -
related development that will lead to congestion and move away from car -
oriented planning and towards a more equitable transportation system.

the growth in driving p• 14.
between 1983 and 1990 was caused by factors influenced by sprawl. These factors
include the same people driving farther, as well as a decrease in carpooling and a switch
from biking, walking, or transit to driving. These changes are in part necessitated by the
spread of subdivisions and office parks isolated from stores and schools. Residents are
often left with no real alternative to driving. One of the unintended consequences of this
growth pattern has been a steadily growing number of vehicle trips that has served to
clog local streets and freeways with traffic and increasingly frustrate residents and
workers. At the same time, the chart shows that population growth accounted for only
13% of the growth in driving.
STPP conducted a rigorous analysis' of more recent data (1992-1997) to examine the
relationships between the growth in driving and other factors measured by TTI. STPP
analyzed the growth of vehicle miles traveled (VMT) versus the growth of population,
growth in the size of the urbanized area, increase in the number of highway lane miles,
and initial density of the urban areae. This analysis demonstrates how the spreading out
of the metropolitan area has contributed to an increase in driving. TTI's data reveals that
every 10% growth in the size of an urbanized area generally has resulted in a 2.5%
increase in miles driven, over and above the increase in driving that comes from
population growth or other factors. The influence of additional road capacity, another
outgrowth of sprawl, is discussed later in this paper.
This analysis indicates that our current traffic congestion problems are not an inevitable
result of the normal, healthy growth of our metro areas. These problems are more closely
linked to the sprawling development patterns that require so much driving.

Why are the Roads so Congested? Road Building has Little Effect on
Congestion

Road Building Has Little Effect on Congestion
Our analysis of TTI's data shows that building new and wider roads has had little long-term impact on road
congestion, and that such roads appear to actually generate additional traffic. In order to control for population
growth, we looked at the amount of highway space per resident each metro area has added since 1982. We split
the 68 metro areas included in TTI's study into three groups and compared the congestion rates for the high and
low group. The high road -building areas increased road capacity per person by 28%, while the low -road building
areas actually decreased road capacity per person by 11 %. Despite this wide discrepancy, the rush-hour
congestion profiles as measured by the Travel Rate Index for each group are almost identical. Interestingly, the
high road building areas show slightly higher congestion levels than the low road -building areas throughout the
period.
One explanation for this outcome is that new and wider roads tend to generate new traffic. This phenomenon,
known as 'induced travel', occurs when road capacity is expanded and drivers flock to the new facility hoping to
save time. The new roadways also tend to draw people who would otherwise avoid congested conditions or take
alternative modes to their destinations. In the long run, this encourages additional development nearby, and that
leads to even more traffic.
Our rigorous analysis of TTI's data' confirms this relationship. In the metro areas studied, a 10% increase in the
size of the highway network has been associated with a 5.3% increase in the amount of driving. In other words,
half of the new highway capacity has been filled with driving that would not have occurred if the road space had
not been added. This is consistent with previous research on induced travel, including an FHWA sponsored
study which found that when additional road capacity provides a 10% improvement in travel time, driving
increases by 5%Z.
