The Round Rock City Council has approved a proposal to amend the City’s noise ordinance to more effectively address loud music late at night in the downtown area. The amendment seeks to find balance between an active downtown with live music and quality of life for downtown residents. The City Council unanimously approved the ordinance amendment on final reading at its March 14, 2019, meeting. It will go into effect on April 15, 2019.
Why is an amendment to the noise ordinance necessary?
Beginning in spring 2018, police began more actively enforcing the noise ordinance and City staff began monitoring noise levels at various locations downtown. We determined the City’s current noise ordinance, which measures sound 200 feet from the property line of the source of noise, has not been effective in addressing the problem.
About the amendment
The amendment adds a new section to the current noise ordinance. The amendment imposes stricter standards to the Mixed Use 1 (MU-1) zoning district in downtown. By requiring noise measurement at the property line, the ordinance will be easier for Police to enforce, and it will reduce the levels of sound reaching residences as well as limit the times when outdoor music can be played.
The amendment, which applies only to the MU-1 district, will require outdoor music venues to apply for a permit. Businesses will be required to obtain a permit annually from the City to operate as an outdoor music venue, which is essentially any business amplifying sound not fully enclosed by walls and a roof, or sound that is regularly projected out a doorway.
Permit holders will be required to follow the time of day restrictions below:
- They shall not operate sound equipment in excess of 80 decibels as measured at the property line of the business from 10 a.m. to 10 p.m. Sunday through Thursday; and from 10 a.m. to midnight on Friday and Saturday.
- At all other times, permit holders shall not operate sound equipment in excess of 60 decibels as measured at the property line of the business. Note: Our original proposal was 50 dB, but after taking some measurements we determined the ambient noise level — often referred to as background noise — is roughly 55 dB in Downtown at night. A 50 dB limit does not meet the intended outcome for the ordinance amendment.
A permit holder who has been found guilty of violating any provisions of this section three times in a 12-month period will have their permit revoked by the Police Chief. The period of revocation will be one year from the date of revocation.
Currently, noise cannot exceed 75 decibels from 9 p.m. to 7 a.m., measured from 200 feet from the property line, in the MU-1 district.
To give an example of the practical difference in the current ordinance and proposed amendment:
- Noise that measures 75 dB 200 feet from a property line (current ordinance) would measure 89 dB at the property line, assuming the source of the noise (amplified speakers) is 25 feet inside the property line.
- Noise that measures 80 dB at the property line (proposed amendment) would measure 61 dB at 200 feet away, assuming the the source of the noise (amplified speakers) is 25 feet inside the property line.
To put those noise levels in perspective, 90db is equivalent to a lawn mower; 80dB is equivalent to an alarm clock or garbage disposal; 75 dB is equivalent to a vacuum cleaner; 60 dB is equivalent to conversational speech or an air conditioner. You can find noise level charts that provide additional examples of various decibel levels here, here and here.
The maps below provide an example scenario depicting a noise source originating 25 feet from a property line measuring 80 decibel levels at the property line vs. a noise source originating from the same location that measures 75 decibels 200 feet from the property line. As you can see, the current ordinance restriction yields higher decibel levels over a much greater area than the proposed ordinance amendment.
We’ve provided an interactive graph to illustrate the difference in decibel levels over distance between the old ordinance and proposed new ordinance standards. With both ordinances, the distance from the property line that a noise originates from is an important variable in determining decibel levels over distance beyond the property line. The interactive graph provides an interactive slider that allows adjustment of the noise source from the property line to illustrate this effect and compare the old ordinance vs. the proposed new ordinance.
