The Public Works Department is made up of various sub-departments including Fleet, Line Repair, Streets/Stormwater and Traffic, Wastewater, and Water. Each week, over 100 employees are responsible for the maintenance, monitoring, and improvement of existing and new infrastructure across League City which includes everything from roadways and traffic lights to storm drains, sewers, and water production.
Below are some tips and projects they are working on:
Wildflower Planting League City Parkway at SH 3
The Public Works Vegetation Management Division has recently dispersed fifteen different varieties of wildflower seeds in the medians along League City Parkway at SH 3. After the seeds were spread a cultipacker was used to press them into the soil. The seeds created by last year’s crop of wildflowers and the seeds that were spread with the tractor mounted spreader will provide good coverage to help ensure an abundance of wildflowers. The Vegetation Management Division, League City Parks Department, and The League City Garden Club is also planning to plant wildflowers on the eastside of Hometown Heros Park. We will continue planting wildflowers at League City Parkway and SH 3 for beautification of League City Medians. The Hometown Heros Park wildflower planting will allow residents a safer up close immersive wildflower experience.
Disk Filter Level Probe
The City of League City Wastewater Department utilizes tertiary disc filters to remove Total Suspended Solids (TSS) from the water before ultraviolet disinfection. The disk filters are comprised of filter media that remove solids from the influent stream. During operation the level of water in the tank is monitored by a level probe sensor and initiates a backwash cycle to clean the filters when the level rises. The level probe was tested for correct incoming voltage and signal voltage. The cable was found to have been corroded, shorting out the signal to the probe. Both level sensor and cable were replaced to provide accurate level measurements.
Water Leak Repairs
Line Repair crews responded to two major water leaks over the last week. The first leak, a fire hydrant connection at the main line cracked, requiring an emergency repair. The second, a 90° bend blew off, also requiring an emergency repair. Crews were able to quickly isolate both leaks and make the necessary repairs and restore water service back to the customers. The crews hard work and dedication to have water restored for the holiday weekend, is what Public Works is all about!
Fuel Gauges Installed on Two Portable Fuel Trailers
Fleet installed fuel gauges on the two portable fuel trailers used by Water and Wastewater. These units are extremely valuable when handling emergency or weather-related conditions and used to fill up emergency generators as well as grapple trucks, backhoes, and loaders.
Unsolved [Bug] Mysteries: League City Edition
Suspect: Southern Yellowjacket (Vespula squamosa)
City Staff met with our local bee expert to identify and propose treatment for an aggressive wasp nest in one of our drainage easements that was interfering with maintenance mowing.
While poking around in the grass nearby, we came across a large, paper-like ground nest. Although the weather was chilly and the wasps were slow-moving, we were able to [very carefully] observe a few of these critters, Southern Yellowjacket (Vespula squamosa), lounging at the top of the nest.
Due to the aggressive nature of this wasp and its location, we formulated a treatment plan to remove the nest and suppress the population. Fortunately, as with most wasp nests, there’s an environmentally-friendly solution—a little soapy water in the form of a high-pressure stream to saturate the nest and suffocate the wasps.
