The focus of this project was a joint effort
among the Federal Emergency Management Agency (FEMA), the
City of Schertz, Texas, located in Guadalupe County, and
Ford Engineering, Inc. to decrease the amount of damage that
results from the area’s historically high occurrences of
100-year flooding. On October 17, 1998, the West Dietz Creek
overtopped it's banks, inundating and blocking access to 80
percent of the city. Water levels in the channel crested
four to six feet over roadways and drainage structures. All
emergency services were completely shut down for six to
eight hours. According to the Guadalupe- Blanco River
Authority, approximately 3,450 structures were heavily
damaged or destroyed and 5 lives were lost in Guadalupe
County during this tragic event. This occurrence triggered a
massive response by the City to curb the recurring tragedies
caused by the flooding of West Dietz Creek. Ford
Engineering, Inc., serving as City Engineer, and acting
under the direction of the City, prepared a study to
determine the improvements needed to contain the 100-year
flood within the banks of West Dietz Creek. This study and
cost estimate was used as the basis of a Hazard Mitigation
Grant Program submitted to the Federal Emergency Management
Agency (FEMA). The grant was approved on October 11, 2002 in
the amount of $3 million, which represented 75% of the
estimated project cost. Design began immediately and Right
of Way Acquisition of over 50 acres was secured. Work began
in June of 2003 and was completed in September of 2005.
This project rectified 1.5 miles of West
Dietz Creek and involved over 700,000 cubic yards of
excavation, 1,500 cubic yards of concrete, 200,000 pounds of
steel, relocation of potable water mains, sanitary sewer
lines, electrical lines, and road reconstruction. This
project succeeded in removing 308 acres of land from the
100-year flood plain.
In June of 2004, the West Dietz Creek
watershed received 8.5 inches of rain in a six hour period.
This was in excess of a 100-year event and the run-off was
totally contained within the banks of the new channel.
The determination of the City Council, led
by a strong Mayor and dedicated staff, working with the
Federal Emergency Management Agency and their City Engineer
secured the grant that funded this project. The City of
Schertz was able to reclaim a vital part of their City thus
insuring the health, welfare and safety of the citizens
during future events. Application of sound engineering
principles, engineering economics and project management
procedures helped assure a successful conclusion to this
vitally needed project.
