Ebb and Flow Header

Runoff from a new development is often conveyed to a detention pond that temporarily stores water and reduces the increase in flows. Since detention is intended to prevent localized flooding, questions begin to arise when downstream residents complain of new flooding issues after construction. Does the detention design meet criteria? Was there an abnormally large storm event? Does the criteria need to be reevaluated?

Recently, the Town of Sunnyvale was confronted with several questions from residents when two recently constructed schools possibly created new downstream flooding...

The City of Wichita Falls developed emergency evacuation plans for Memorial Day rains, with the help of Freese and Nichols. The weather service was projecting a potential flood of record for the Wichita River.

Within a matter of hours, we developed flood maps that they could use for emergency management operations, sending GIS files for floodplain delineations of a variety of flood stages corresponding to the potential flood stages. The City pulled the maps up on the screen at the emergency operations center and went to work making their emergency evacuation plans.

Our work to preserve and improve Fort Hood's stormwater infrastructure with a comprehensive Stormwater Management Program has been featured in Public Works Digest. We helped the army installation take stormwater inventory of their 340 square miles, offering solutions to develop a long-range vision, rather than reactionary measures. They have been implemented our suggested improvements to ease flooding issues. Solutions range from upsizing culverts and storm drains, adding inlets, widening and improving open channels and adding detention ponds. Fort Hood continues to develop its stormwater...

With the recent storms in the southwest United States, many of the regional lakes are at or above capacity, including in the North Texas Region. Water is being released from lakes at a higher rate than normal, which may potentially cause river flooding downstream. Municipalities and communities may need to warn residents and business owners in flood-prone areas in a timely manner for public safety. The National Oceanic and Atmospheric...

Members of our North Texas Stormwater Group toured Arlington project sites to check on their progress this month. 

They toured a site by golf cart, checking on Village Creek erosion repairs throughout the Lake Arlington Golf Course. Freese and Nichols provided hydrologic and hydraulic modeling, stream geomorphological assessment and design services for storm drainage and erosion improvements to alleviate erosion throughout the sites. Improvements included about 850 feet of low maintenance, stable channel solutions and water line rehabilitation suspended from two golf cart path...
