Title
Consider and take action on a resolution approving the installation of three speed humps along Cedar Prairie Drive (Executive Director of Development Services)
Background
A citizen requested the installation of three speed humps on Cedar Prairie Drive, a local roadway approximately 1,200 feet long (shown in Exhibit A). The request included meeting minutes from the Homeowners Association (HOA) showing a vote in favor of installing speed humps and signatures from over two-thirds of the property owners on the study stretch (petition and map provided in Exhibit B).
The estimated total cost for the three requested speed humps is $5,360.00. Per City Road Hump Policy (provided in Exhibit C), the cost of the speed humps is usually shared equally between the City and the HOA and/or applicant. The cost estimate for material and installation of the speed humps was provided to the applicant, and they confirmed no objection to bearing a 50 percent share of the cost. Speed humps may be furnished as prefabricated systems and are not required to be permanent in nature.
A speed study was performed in accordance with guidelines provided in the TX Manual on Uniform Traffic Control Devices (TX-MUTCD) (Speed Study provided in Exhibit D). Based on the study, a speeding issue was not identified along the study stretch: the posted speed limit is 25 mph, and the 85th-percentile speed was found to be approximately 30 mph. The segment where speed humps were requested lies along the southern boundary of the neighborhood, with three north-south roadways drawing local traffic toward FM 518, but only one east-west roadway connecting this area to Landing Blvd. Given this localized circulation pattern, it is reasonable to assume the faster drivers in this segment are predominantly nearby residents. Three north-south roadways connecting to FM 518 in the neighborhood currently host speed humps -- namely Clear Creek Meadows Dr., Green Cedar Dr., and Cedar Branch Dr.
The study recorded an average daily traffic (ADT) of 530 vehicles. Data was collected between May 13, 2025, at approximately 1 PM and May 16, 2025, at approximately 1 PM. Among vehicles exceeding 25 mph, the average speed was slightly less than 30 mph. The maximum speed noted during the study was 48 mph and occurred on May 14, 2025 at approximately 5:47 AM. A review of the TxDOT Crash Records Information System (C.R.I.S.) shows no reported crashes along this roadway segment between May 2024 and May 2025.
League City Police and Fire Departments were provided with the citizen request and the speed study. Both departments recommend not installing speed humps on Cedar Prairie Drive due to impacts on emergency response. While Engineering concurs that speed humps are technically not warranted at this time (85th-percentile speed is only 5 mph over the speed limit), the level of HOA and resident support should be considered. Given the localized nature of traffic flow and the successful deployment of speed humps on other north-south neighborhood streets, the addition of speed humps on the east-west Cedar Prairie Drive as a traffic calming measure would carry mostly benign impacts and not prove significantly consequential to the delivery of services.
If no devices are approved, Staff will install supplemental signage to highlight the legal 25-mph speed limit in accordance with TX-MUTCD guidelines.
