The American Surveyor Vol 8 No 7

Editorial: Putting the Lean On Manufacturing—A Visit to Topcon
The manufacturing area of Topcon's US headquarters in Livermore, California was a veritable beehive of activity during my recent visit. Colin Kavanagh, Senior VP for Operations, called attention to the "lean" manufacturing processes that have "eliminated expenditures for resources for any goal other than the creation of value for the end customer". To achieve this, Topcon cast a critical eye on ....

Surveying with Google Earth
Over the past few years, I have become convinced that Google Earth represents an extraordinary opportunity to visualize and communicate survey data, though I too was skeptical of its value as a professional land surveying tool in the beginning. At the time, Metzger + Willard, Inc. (MWI) was making AutoCAD base maps with orthophotos in the vicinity of NGS control stations. Our reasoning was that, equipped with ....

Well, the county ....

Surveyors Being Blamed for Ike-damaged Homes

By Eric Dexheimer
March 3, 2009
Austin American-Statesman, Austin, TX

It’s not often we get to use the words “investigation” and “Texas Board of Professional Land Surveying” in the same sentence.

At last.

Typically, the state surveying board flies well below the public radar. The vast majority of its enforcement actions involve low-level boundary disputes, about 60 a year.

But late last month the agency recommended an unusually large $6,000 fine for each of two South Texas surveyors accused of violating state rules. The mistakes the surveyors are accused of making, however, will probably end up costing a couple dozen Texas homeowners hundreds of thousands of dollars.

First, the history, courtesy of TBPLS investigator Garey Gilley: Years ago, the Federal Emergency Management Agency let cities and counties choose if they wanted to participate in its flood insurance program. Those that did agreed not to permit any buildings below what came to be known as the base flood level.

Jefferson County decided that the ground floor of structures had to be at least one foot above base flood elevation (also known as the 100-year flood plain). Structures built above that mark were not required to have flood insurance. Local surveyors pinpointed the base flood elevation using 30-year-old federal measurements inscribed on concrete-and-brass monuments erected by the National Geodetic Survey.

In the mid-1980s, FEMA published a new flood insurance rate map, but with different measurements. It recalculated the base flood level based on a new study showing that the Beaumont-area flood plain had actually shifted about three feet since the federal government’s first measurements in the 1950s.

But, Gilley says, local surveyors didn’t know about the new map. They continued to rely on the old NGS elevation numbers. Unfortunately, that meant that people who thought their new homes were being built above flood level were actually building two feet below it.

Gilley says about 20 homes near LaBelle were mis-constructed. “That’s what got the surveyors in trouble,” he says. “They never looked at the new FEMA map.”

The three-foot difference became crystal clear in 2008, when Hurricane Ike hit the Texas coast. Some residents whose homes should have been above the flooding found themselves wading in water instead.

Worse, because of the wrong measurements, they had not bought flood insurance. And now that the homes were in a recognized flood plain, FEMA would not permit them to be rebuilt.

Although two surveyors — Soutex Surveyors Inc., of Port Arthur and Harold F. Locke and Associates, of Port Neches — are the current target of the Board of Professional Land Surveying action (see the agency’s report here) Gilley says other surveyors are being investigated for making the same expensive mistake. The three-foot discrepancy has also spawned a half-dozen lawsuits against Soutex.

According to Gilley, there are many similar areas across Texas, where, unbeknownst to homeowners, new FEMA maps disagree with old federal measurements. “There are absolutely more situations like this,” he says.

Surveyors Face Penalties for Elevation Certificates

February 9, 2009 - 6:34 PM

Two Southeast Texas surveyors will be penalized for mistakes in determining the elevation of homes in West Jefferson County. KFDM News has learned one of those surveyors is Anthony Leger from SouTex surveyors in Port Arthur. The board has not released the name of the other surveyor but decided they both broke at least five board rules.

The US Geological Survey identifies benchmarks and sets elevations. FEMA uses that information for its flood maps. Surveyors are required to use FEMA's numbers. In this case, FEMA changed the elevation of areas in Jefferson County by three feet. However, many surveyors were not made aware of the change. At least 160 homeowners want to take advantage of a government buy-out because of questions about elevation.

"FEMA didn't bother telling anybody about it. They were relying on information they had. It was erroneous," said Tom Roebuck.

Many people who live in the Country Road Estates neighborhood found out their home elevations were off by three feet. One of the people who helped bring that to light was in fact, Anthony Leger. Now he and others could face penalties, ranging from a fine all the way to the maximum, license revocation. Garey Gilley with the Texas Board of Land Surveying says that's unlikely.

"I do not believe it will be the maximum. I assure you it will not be revocation of license. We'd have to demonstrate they knowingly disregarded over time," said Garey Gilley.

Staff members should make a final decision by Tuesday. Others who want to file complaints can do so by filling out a complaint form on-line at the board's website. If the surveyors are found in violation, they'll face the same penalties.

KFDM News has learned two Southeast Texas surveyors who shot elevations of homes in West Jefferson County could face punishment for how they carried out their work. The Texas Board of Land Surveying met in Austin Friday.

It's decided two Southeast Texas surveyors violated at least five board rules.

The surveyors filed elevation certificates for families living in the Labelle-Fannett area of West Jefferson County. After Hurricane Ike, homeowners in that area found out their elevations were off, in some cases three feet lower than they thought. As a result, many people in Country Road Estates had several feet of water inside their homes. Some lost everything.

A few homeowners have filed civil lawsuits against their surveyors. They want to recoup the 25% of the lost value of their homes not covered by FEMA.

Monday two staff members from the board will decide the appropriate disciplinary action. That could include a fine or the maximum penalty, losing their licenses. The two surveyors have the option of telling their side of the story before the Texas Attorney General. The board will have the final say.

As for any other property owners who file a complaint against a surveyor, those complaints will be investigated by the board and if it rules against the surveyers, the same range of punishment is guaranteed.
