LPESA Scholarship AwardedPresented at the LPESA Annual Meeting
This years LPESA scholarship was presented on
February 22, 2007, at the General Members Meeting,
which was held during the annual Police Jury
Association Conference at the Louisiana Cajundome
in Lafayette. This annual scholarship of $1500 is
given by LPESA to encourage interest in public
The Louisiana State Chapter of the American Public
Works Association has been consolidated from three
chapters to one chapter. The organization will now
have the Baton Rouge, New Orleans, and North
Shore branches operating under one state chapter.
This new merger results in no increased fees and
allows local chapter members to participate in activi-
ties outside of their area. These changes were dis-
cussed at the first meeting of the APWA Chapter,
held on February 28, 2007, at Andreas Restaurant in
Metairie.
This first meeting was attended by some special
national guests, including Peter King, APWA
Executive Director, and Dan Jensen, APWA
Governmental Affairs Manager, both from
Washington, D.C. Other important guests represent-

Keep Louisiana Beautiful
In Louisiana, taxpayers pay over $15 million each
year in state funds alone to clean up our highways.
Local jurisdictions together spend millions more.
Louisiana has a serious litter problem which Keep
Louisiana Beautiful (KLB) is aggressively working to
improve.
Keep Louisiana Beautiful, part of the Keep America
Beautiful network, is a volunteer-based service
organization dedicated to a healthy and litter free
Louisiana. Through a network of community affili-
ates, KLB promotes its mission to educate
Louisianans on the ecological and economic effects
of littering.
KLB recently announced the winners of the 2007Community Grant Program. They are: Keep
Mandeville Beautiful, Keep Slidell Beautiful, St. John
Parish Sheriff's Office, Keep New Iberia Beautiful,
Keep St. Martin Beautiful, Lafayette Consolidated
Government, City Year Louisiana, Baton Rouge
Downtown Development District, Faubourg St. John
Neighborhood Association, Team Green of
Southwest Louisiana, Keep Cenla Beautiful, Keep
Leesville Beautiful, Shreveport Green, Keep
Keep Louisiana Beautiful
Morehouse Beautiful, Keep West Monroe Beautiful,
and the Louisiana Department of Wildlife and
Fisheries.
Highway litter is a major area of focus for KLB since
its consequences are broad and far-reaching. Illegal
littering and dumping on our states highways is
dangerous, costs tax dollars, detracts from the states
natural beauty, and negatively affects wildlife.
One of KLBs primary concerns this year is cigarette
butt litter on our roadways, waterways, and scenic
areas. This is the most littered item in the world andLouisiana is no different. Through education,
enforcement, and KLBs awarding of community lit-
ter grants, were working to reduce this blight, com-
mented Keep Louisiana Beautiful Executive Director
Leigh Harris.
The importance of Louisianas highways remains of
critical importance to KLB. Even the first few sec-
onds of our television commercial shows a vehicle
driving down a pristine Louisiana roadway. Tossingtrash out of a moving car is such a common prob-
lem, and we wanted people to link this image with
our campaign message: Louisiana. Dont Put It
Down.

Trenchless Rehabilitation for Culverts
Culvert maintenance is very important in limiting
the natural decay of culverts. Many culverts in the
United States have deteriorated to a point of needingreplacement. In the past, culvert maintenance was a
large-scale construction job that included trench dig-
ging and high project costs. However, many agen-
cies including the Federal Highway Administration
(FHWA) have turned to a trenchless rehabilitation,
which negates these much higher construction costs.
Trenchless operations have evolved into a standard-
ized approach, which was drafted by Colorado State
University (CSU). CSU analyzed several commonmethods applied to lining techniques and was able
to finalize a list of nine methods. CSU also incorpo-
rated a Microsoft Excel spreadsheet that guides the
user to select the proper lining method. The follow-
ing methods are included in the study:
Standardized Methods
Sliplining segmental
Sliplining continuous Close-fit lining deformed/reformed
Close-fit lining fold and form
Spirally wound lining
Cured-in-place pipe lining inversion
Cured-in-place pipe lining pulled in place
Spray-on lining cement-mortar
Spray-on lining epoxy
While the method of proper lining and maintenance
approaches has been resolved, the question of
whether to replace or reline a culvert remains.
FHWA is funding a study titled Coordinated
Technology Implementation Program (CTIP), which
will produce these guidelines later this year.
A copy of the findings, entitled Culvert Pipe Lining
Guide 2005, is available online at
www.cflhd.gov/techDevelopment/completed_pro-
jects/hydraulics/culvert-pipe-liner in PDF format.

Keeping Your Bridge Deck Free of Debris
By Ralph K. Banks, P.E.
An important aspect of good bridge maintenance is
keeping the bridge deck free of debris. This debris
(which usually consists of sand, soil or gravel) can
accumulate moisture, keeping the deck surface wet
for long periods of time. The prolonged presence of
moisture can eventually cause premature damage to
the deck, not only when the deck is constructed of
concrete, but when constructed of timber or steel as
well. For concrete or steel decks, this moisture can be
even more damaging if it contains residual deicingchemicals, such as salt. And the continued presence
of wet soil and gravel on a timber bridge deck can
cause premature decay of the timber. Another reason
for keeping the bridge deck free of debris is to avoid
eventual intrusion of this debris down into the con-crete deck expansion or pour joints.
Concrete deck expansion joints are designed to allow
expansion of the deck during warm weather, but if
the joints have been filled with incompressible
material, such as debris, then expansion cannot
occur. This can possibly cause fracture damage to the
deck, or even damage to under-deck elements such
as beams, girders, bearings and substructure caps.
Accumulated debris on a bridge deck also has a wayof finding its way into and clogging the deck
drainage system. With such clogging, ponding of
rainwater drainage on the bridge deck can occur,
-

and this ponding in either liquid or ice form can
cause skid-resistance hazards to traffic. Ponded sur-
face water can also facilitate corrosion of concrete
reinforcing steel, which is made even more likely if
the water should contain deicing chemicals.
If the bridge is located on an unpaved road, road
material may be tracked onto the bridge by routine
traffic, or may have been pulled onto the bridge bymotor grader operations in grading and shaping the
bridge approaches. A good remedy in these instances
is to pave short sections of the bridge approaches
next to the bridge ends with asphaltic concrete mate-
rial or surface treatment. Yearly cleaning of the
bridge deck is usually sufficient to keep the deck
clear of this unwanted debris. Typically, these clean-
ings should take place in the spring after the last
application of deicing salt or sand-salt mixtures.
These cleanings should also include the removal ofany debris that has already become lodged in the
bridge deck joints and drainage system, as well as
any debris that has fallen through the deck expan-
sion joints onto the substructure caps underneath.

Vehicle Safety:
Avoid Backing Accidents
One of every four accidents involves backing.
Considering that the average driver operates in reverse
less than a mile every year, this statistic is even more
alarming.
The following are key collision failures related to back-
ing operations:
1. Failure to look before backing
2. Failure to check blind spots
3. Failure to conduct a walk-around
4. Backing at an unsafe speed
5. Failure to check mirrors often for potential hazards
The following tips will help you avoid collisions while
backing:
1. Continuously check all mirrors while backing.
2. Always back slowly while continuously looking and
listening for signs of trouble.
3. Avoid backing whenever possible. Drivers should plan
ahead to reduce backing operations in the first place.
4. If backing cannot be avoided, it is better to back in
upon arrival than to back out later while departing.
5. Conduct a visual walk-around of the vehicle to check
for maneuvering room or pedestrians.
6. Whenever possible, use a passenger to guide you dur-
ing backing operations.
All backing accidents are preventable. The key is to plan
ahead to avoid backing in the first place. You should
only back up your vehicle as a last resort.
LTAPs workshop, Coaching the Maintenance Vehicle
Operator, includes vehicle safety and avoiding backing
accidents. Call David McFarland at 225-767-9118 to
schedule a class for your drivers.

LTAP Participates as Part of Team to Develop and
Implement
The Plan An Overview
A State Wide Focus: Louisianas Strategic Highway
Safety Plan (SHSP) was officially signed at the
Annual Louisiana Highway Safety
Summit on September 7, 2006. The SHSP
was a culmination of an extensive collab-
oration between key transportation and
highway safety partners, including LTAP.Each state was required to develop a plan
under the recently reauthorized highway
bill, the Safe, Accountable, Flexible,
Efficient Transportation Equity Act A
Legacy for Users (SAFETEA-LU).
Applicability at the Local Level
LTAP participated in the development of
the plan and was identified as a key
member of the SHSP team. This desig-
nation in the SHSP and participation in
the planning efforts further solidified
LTAPs steady progress towards imple-
menting a more aggressive approach to improving
safety on Louisianas local road system. The
Louisiana Local Road Safety Program, which began
in 2006 and is coordinated by LTAP, is a primary
mechanism to providing a more comprehensive
approach to local road safety. LTAP is working with
the SHSP team to coordinate efforts at the local level
and to bring proven strategies to the local road sys-
tem.
Vision, Mission and Goal
Louisianas SHSP is extensive and contains detailed
information about Louisianas current highway safe-
ty profile, which is among the worst in the nation, as
Louisiana Strategic Highway Safety Plan
well as planned strategies to improve the safety of
our roads. It also contains a very simple and clearvision statement: Louisiana travelers arrive safely at
their destinations. At the end of the day, this is what
all transportation professionals and those who use
our roads expect and envision.
The Mission is Just as Clear
To reduce the human and economic toll on
Louisianas surface transportation system due to traf-
fic crashes through widespread collaboration and an
integrated 4E approach. In 2005, fatalities on
Louisianas roads totaled 965, resulting from over
165,000 crashes. The cost associated with the number
of crashes and fatalities is staggering. One estimate is
that the cost of traffic crashes in Louisiana is over
$2,013 per year for each licensed driver in the state,
for a total of approximately $5.97 billion dollars. This
accounts for about 4.5% of personal income (based
on cost estimates by NHTSA, 2000). The 4E approach
integrates the critical components of engineering,

education, enforcement, and emergency services.
This multi-disciplinary approach, including thefifth E of everyone else, is acknowledged to be
the one way to make significant progress.
The primary goal of the plan is to: Reduce the
Louisiana fatality rate to 1.54 per 100M VMT by
2010. This ambitious goal reflects the fact that in
2004, the states fatality rate was 2.23, considerably
higher than the national average of 1.46. A reduction
to 1.54 will result in almost 200 lives being saved.
How Will We Accomplish the Goal?
To reach this identified goal, the Louisiana highway
safety community will work towards a set of objec-
tives by identifying and enhancing current strategies,
by adopting other strategies that have proven effec-
tive in other states, and by measuring performance
on a continual basis. The following objectives are
being actively pursued:
implement an effective, comprehensive systems
approach for improving road user behavior;
use a systems approach in engineering to strike a
balance between single unique locations and
addressing the safety of the road network;
develop comprehensive, timely and accurate infor-
mation and decision support systems; and
develop a comprehensive, data driven legislative
safety agenda that all partners actively support and
implement.
Your/Our Role in Roadway Safety
The LTAP designation as an SHSP team member is a
significant recognition of the issue of local road safe-
ty. Louisianas road safety problems require collabo-
ration at the state and local levels and must include
comprehensive approaches that include driver
behavior, engineering, data for decision making, and
a legislative agenda that supports law enforcement
efforts to reduce impaired and reckless driving. The
Louisiana Local Road Safety Program providesresources to assist local agencies and communities in
improving road safety in their parish or municipali-
ty.
Many organizations, local governments, and com-
munities will be involved with developing imple-
mentation and action plans, as will state groups and
the law enforcement profession. It will take us all
working together to solve the road safety crisis in
Louisiana.
