FIRMs Under Review With a Focus on Levees
In 2005, Hurricane Katrina demonstrated that levees are not created equally, nor do they all age gracefully. Prior to the breach of the Mississippi River levee in New Orleans, flood delineations shown on Federal Emergency Management Agency (FEMA) Flood Insurance Rate Maps (FIRMs) indicated that the areas behind levees were protected – that is, outside the flood limits of the base flood. Motivated by the impacts of Hurricane Katrina and other storm events throughout the U.S., FEMA is now reviewing and revising (as appropriate)...

What is Hydroacoustic Technology?
In general, hydroacoustic technology is technology that applies sound to water to collect data and information. When used to quantify discharge/depth relationships and flow velocities, hydroacoustic technology can improve the accuracy of hydraulic modeling. This ability to collect real-time field measurements of discharge and flow velocities is a recent and important advancement in our field, as it allows professionals to take specific, current measurements of ungaged streams and rivers quickly and easily.

FNI conducted a stormwater funding survey of Texas municipalities and found that more than 60 percent of participants relied completely on one funding source for their stormwater projects. Particularly in today’s economy, this kind of funding dependence can severely limit a municipality’s efforts to protect its citizens from stormwater flooding. Diversifying funding sources helps enable communities to continue diligent monitoring, provide regular maintance and improve their systems while weathering the storm of the current economic climate.

In a difficult economy, many clients question spending additional, already-tight project funding to design their stormwater management projects to accommodate a 100-year storm and/or flood, which has a low probability of occurring. However, this decision should be weighed heavily. Saving project capital now could put your community at a significant risk later.

They Happen More Often than You Think
It is commonly believed that 100-year storms and floods occur once every 100 years, but according to the U.S. Geological Survey (USGS), 100-year storms and floods...

Obtaining public input and buy-in is often a critical component of stormwater management design projects, and effectively demonstrating the need for and potential effects of a proposed project is crucial to successfully communicating with the general public and keeping a project on track. Visual illustrations often prove to be the most valuable and efficient means of demonstrating a project’s effects to the public, and the introduction of dynamic stormwater modeling software presents...

The staff at Fort Hood take great pride in providing an environment to train U.S. troops to protect our country and our interests around the world. While serving this important mission, Fort Hood is required to comply with Clean Water Act requirements to protect water quality from pollution in urban storm water runoff. Like many cities throughout Texas and the U.S., Fort Hood is an operator of a Phase II Municipal Separate Storm Sewer System (MS4) and is in the midst of implementing a storm water management program in the urbanized areas of the installation.

Project Background 

When the 23 dams in the Upper Brushy Creek watershed in southern Williamson County were built by the U.S. Soil Conservation Service in the 1960s, they met all safety standards for earthen dams in sparsely populated areas. Now, 21 of those dams provide flood control for one of central Texas’ fastest growing populations and, due to increased potential risk to the public (risk creep), are classified as high hazard dams. 

In 2000, the Upper Brushy Creek Water Control and Improvement District (WCID) was directed by the State of Texas to bring...

Small cities, counties and other regulated entities are now in the third year of their first five-year permit to implement their Phase II MS4 program to protect water quality from pollutants in stormwater runoff. Year-to-year progress towards implementation must be demonstrated to the TCEQ until the full program is in place by August 2012. Some of the challenges and potential solutions faced by those implementing Phase II MS4 programs are discussed below.
