[ARCHIVED] Public Works' Week in Review

public works in action2

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 

Fleet Department - 84" Sweeper Attachment 

Vehicle Maintenance Division assembles the sweeper attachment  for Street Department.

Our Fleet Department prepared and assembled a new sweeper bucket to add to the arsenal of bobcat attachments. This new sweeper will help clean and maintain curbs, roadways, and medians. This attachment will be especially useful during road construction or maintenance projects.

Our Fleet Department prepared and assembled the 84" sweeper attachment for the skid-steer that will be utilized by the Streets Department's Rapid Response Crew. The sweeper attachment has a broom bucket with an enclosed clamshell along with a water kit and gutter brush. This attachment will be especially useful for cleanup and maintenance of City roadways, curbs, and medians due to road construction and maintenance projects.

Vegetation Management

The Public Works Vegetation Management Division worked with the League City Garden Club to sow 15 different varieties of wildflower seeds into the soil along League City Parkway at HWY 3. This year’s seeds were sown using two different methods. First, we rototilled the west side of HWY 3 along League City Parkway and sown the seeds into the freshly tilled soil.  Second, we used a seed drill to sow seeds on the east side of HWY 3 by the Wildflower Project sign, A seed drill is a tractor mounted seed spreader that takes the seed and drops it thru a tube in-between two discs that cut a shallow grove into the soil and a wheel behind discs packs the open grove to sow the seed. The seed created by last year’s crop in a combination with the seed drill will provide a good seed bed for next year’s wildflowers.

Southern Yellowjacket Wasp Nest

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.

Wastewater – Fight Holiday F.O.G (Fats, Oils and Greases)

The Wastewater Department wants to remind residents gathering this holiday season to trash their FOG (Fats, Oils, and Greases). Improper disposal of FOG can lead to costly plumbing repairs or an unpleasant sewer backup. To avoid these clogs and costly plumbing issues, here are a few ways to keep drains clear during this Holiday Season:

  • Pour cooking oils and grease into an impermeable container with absorbent material, such as a paper towel, coffee grounds, or kitty litter and dispose of it in the trash or recycle at an environmental recycling site
  • Scrape food from dishes into the trash (not the garbage disposal) and wipe down greasy dishes with a paper towel before washing
  • Filter and reuse large amounts of deep-frying oil
  • Refrigerate and reuse fats for cooking
  • Prevent food from entering your drains by covering your kitchen sink drain with a strainer
  • Limit your use of garbage disposals; they do not prevent grease buildup
  • Hot water does not help grease through the sewer; it only causes the clog to be further down the line, possibly leading to costlier repairs

Water Production - Pump Control Valve Maintenance

Water Production Maintenance team continued preforming proactive maintenance by servicing  one of our high service booster pump control valve’s at our S.Hwy3 booster pump station. Service includes de-energizing motor, isolation valves. Removal of valve cover. Inspection and cleaning of valve body and other internal parts. Replacement of O-rings, seat rings and U-cup liner gasket. Keeping these valves reliable and operational is key to ensuring the water supply for the residents of League City.

Line Repair – Update on Bensons Bayou 16" Water Line Leak

Leak repaired!! As stated in last week’s “Public Works' Week in Review”, Line Repair Department had begun excavation to determine what needed to be done in order to make repairs to the 16” water line leak. Once all safety protocols were followed, crew members were able to determine there was a dime sized hole in the 16” steel water main. The protective coating was removed and a 16” x 15” long stainless steel repair clamp was installed to make the repairs. The trench box was removed and the hole was backfilled and dressed up to allow proper flow for Benson’s Bayou to be restored.
