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

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,


5/8

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.
