RE: City of Rowlett – Environmental Noise Assessment Dear Mr. Tilger,
At your request, we have conducted an environmental noise assessment regarding sound levels associated with the Bodin and TXI concrete batch plants located within the industrial district near Boyd Boulevard in the City of Rowlett, TX. This industrial district is located just north of a residential district which includes the neighborhood Dexham Estates.
On-site sound level measurements were conducted over a 14-day period to evaluate whether the current noise environment in the industrial district exceeds the City of Rowlett noise ordinance at the property line of the nearby residential district. The results of this noise assessment are documented in this report. Also included herein are detailed graph illustrations and tables of the measured sound level data for your use.
Applicable Noise Standards The following noise standards are provided below for your information.
Article V: Noise: Section 22-204 – Limitations on Environmental Sound Levels of the City of Rowlett Code of Ordinance states:
a.) It shall be a violation of this article for any person to operate or permit to be operated any stationary sources of sound that create a tenth percentile level (L10) or a 90th percentile sound level (L90) that exceeds the limits set forth in the following table for the receiving land use districts when measured five feet above the property boundary.

On-Site Sound Level Measurements Continuous 24-hour sound level measurements were conducted simultaneously at two locations between 12:00 p.m. Tuesday, February 9, 2010 and 12:00 p.m. Tuesday, February 23, 2010 to document the existing noise conditions. One sound level meter (SLM-I or Industrial) was

positioned in the tree line just west of the dead-end portion of Boyd Boulevard to document noise levels in the industrial district and the other sound level meter (SLM-R or Residential) was placed in the tree line near the alley connecting Palomino Drive and Stallion Circle near the residential property line of the Dexham Estates; please see measurement locations on the attached aerial photograph.
Larson-Davis 831 Type I Sound Level Meters were used as data-collection devices at each measurement location. The microphones were fixed to tree branches at an approximate height of 5 ft above grade to simulate the average height of the human ear. The sound level meters measured A-weighted sound pressure level data continuously over the 14-day period, logging applicable sound level data averages (L10, L90, and Leq) at 30-minute intervals to document the typical hour-to-hour noise environment at each location.
As stated in the Applicable Noise Standards section above, the City of Rowlett noise ordinance requires the collection of the statistical noise descriptors L10 and L90 to describe the time-varying character of environmental noise. They are the noise levels equaled or exceeded during 10 and 90 percent of a stated time, respectively. Sound levels associated with L10 typically describe transient or short-term events (e.g. alarms, train whistles, etc.), whereas levels associated with L90 describe the steady-state (or most prevalent) noise conditions.
The City of Rowlett has also requested the Equivalent Sound Level (Leq) data. Because community noise fluctuates over time, Leq is often used to describe the time-varying character of community noise. The Leq is the energy-averaged A-weighted sound level during a measured time interval, and is equal to the level of a continuous steady sound containing the same total acoustical energy over a given time period as the actual time-varying sound.
Data Analysis The sound level data recorded at each location were plotted on separate graphs for each 24-hour measurement period included in the 14-day environmental noise study. The graphs show L10, L90, and Leq data along with the applicable sound level limits as stated in the City of Rowlett noise ordinance in order to compare the measured values to the ordinance limits.
At certain instances during the noise assessment measurement period, measured data was documented to be very close to the ordinance limits. If the data on the graphs appear ambiguous, notes were made stating whether or not the noise ordinance limits were exceeded. To further verify the charted information, all data were recorded in tables organized by date. The data in the tables include the Record# (or meter logging number), Time Frame, and Leq, L10, and L90 sound levels for each of the 30-minute intervals during our 14-day study. All charts and tables are attached to this report for your use.
Since the residential area is of particular interest, data from measurement location SLM-R were compared to data from location SLM-I to determine any possible correlations between levels produced in the industrial district and levels received near the residential area. Measurement data were also compared to the area trash collection in order to eliminate any instantaneous data excluded from the City’s noise ordinance. Train schedules were not available during the time of this analysis; therefore, any noise related to the nearby railway and its effects on the measurements conducted in this study cannot be commented on in this analysis.

ResultsData shows that the sound level limits set forth in the City’s noise ordinance for residential land use have been exceeded a total of seven (7) times at measurement location SLM-R near the Dexham Estates neighborhood by a maximum of 3 dBA during our 14-day noise study. Table 1 below summarizes these occurrences and compares the measured sound levels to the City’s ordinance residential sound level limits. As shown on the table, all occurrences took place in the nighttime hours between 5:30am and 6:30am when the noise ordinance limits are more stringent.

Table 1 – Summary of Exceeding Noise Ordinance Level Occurrences at Residential Property Line (SLM-R)
ConclusionsAfter comparing the data at the two (2) measurement locations, no consistent pattern was found that would accurately correlate sound levels from the industrial district with the measured levels at the residential property line exceeding the 50 dBA noise ordinance limit as shown above in Table 1. Since the meter at SLM-R was not monitored on-site during these times, we are unable to determine the cause of the increased sound levels. Since each of these occurrences take place during that specific period of time, it is not unlikely that other noise sources that are exempt from the noise ordinance such as animal noise (birds chirping, dogs barking, etc.), vehicular traffic, airplane overflight, lawn maintenance equipment, and public park attendees may have contributed to these increased sound levels. Train schedules were not available during the time of this analysis; therefore, any noise related to the nearby railway and its effects on the measurements conducted in this study cannot be commented on in this analysis.
I trust you will find this information helpful. If you have any questions or concerns, please do not hesitate to contact us.
