The North Texas Land/Water Sustainability Forum is organizing a Low Impact Development (LID) design competition in Dallas/Fort Worth (DFW). The competition includes designs for four professional projects and one student project, all located within the DFW Metroplex. The professional competition features projects in urban redevelopment, green streets, mixed use development and multi-family development while the student competition focuses on urban residential redevelopment.  Contestants are challenged with creating a design for each of these projects using iSWM design techniques for low...

The Texas Water Development Board is expected to have funds available in the Water Infrastructure Fund (WIF) left from the previous year’s appropriations to implement State Water Plan projects. The deadline to submit applications for this funding is August 1, 2012. Please note that after this funding is spent, no additional funding will be available for this loan without legislative authorization. Although the voters approved a $6-billion debt offering, these funds will not have incentives, discounts or deferrals until the legislature provides a revenue stream for the debt service on those...

Freese and Nichols is now part of a new InfoWorks Texas User Group (IWTXUG) comprised of other firms and municipalities. The group has developed a website with goals to facilitate:

  • More coordinated discussions with Innovyze
  • Provide links to discussion groups for dealing with modeling issues
  • Identifying training needs and scheduling training
  • Other purposes as they may arise

Thus far, the group has met with Innovyze representatives to discuss the new ICM software, customer support issues, and feature...

In March 2011, FEMA agreed to end its policy of disregarding non-accredited levees and flood structures in the process of updating FIRMs. This “all or nothing” approach to evaluating levees and the flood risks behind them affects levee owners who cannot or will not develop technical data for FEMA accreditation of their levees.

New Rules Proposed, Now Being Finalized
FEMA has now proposed new rules for “Analysis and Mapping Procedures for Non-Accredited Levees.” These rules were provided for public review, and the comment period ended January 30. FEMA is now...

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.
