Garden Township Passes Police Power Noise Ordinance

December 9, 2014

Garden Township, Michigan board members voted with four in favor, one abstaining, to pass a police power noise ordinance limiting industrial noise emissions in the township to 35db between the hours of 10pm and 6am.

What does a wind turbine sound like?

How loud can the wind turbines get?

Because there was no specific zoning in place at the time of the construction of the current 14 turbines in the Garden Wind Farm, Heritage does not have to adhere to any county noise zoning requirements. Residents of the Garden Wind Farm report that wind turbine noise regularly exceeds reasonable, acceptable decibel levels within the project, preventing them from enjoying their homes and property and leaving them at risk for noise-related health issues. 

Wind turbine manufacturers recommend keeping noise levels within 'relative noise limits': 

Turbine noise emissions must not exceed the level of background noise (both turbine and background noise are measured as a function of wind speed); such limits are often supplemented with a low absolute maximum noise limit to cover those situations in which turbines are located in areas of very low background noise.

Noisy Turbines = Higher Revenue

Without zoning in place to regulate noise, Heritage takes advantage of our hospitality on the Garden Peninsula. VP of Operations Rick Wilson operates the turbines without regard to neighboring parcels and our health, ability to sleep, and enjoyment of our properties, regardless of numerous complaints from residents. In a July Garden Township meeting, Mr. Wilson stated he could regulate the noise emitted by the wind turbines, but doing so would adversely affect revenue.


We asked for relief

In October 2012, over 70 residents of Garden Township presented Delta County Commissioners with a petition seeking intervention for noise relief. The petition was ignored.

Subsequently, we asked for greater setbacks, better noise controls, consideration to our safety, protection of our property rights. The response from Delta County was the permissive zoning that we are addressing today. Are revenues to the county really worth more than the health, safety and welfare of residents?

How is the County Protecting Us Now?

The County requires the next phase of turbines to adhere to the following noise limitations: 

Sound Pressure Level: The sound pressure level shall not exceed either 55 dB(A) measured at the property lines or the lease unit boundary, whichever is farther from the source of the noise, or 45 dB(A) measured at an existing dwelling, whichever measurement is less. This sound pressure level shall not be exceeded for more than three minutes in any hour of the day. If the ambient sound pressure exceeds 55 dB(A), the standard shall be ambient dB(A) plus 5 dB(A). 


Garden Wind Farm residents can tell you that these restrictions will not adequately protect our ability to sleep and the enjoyment of our property!

Acoustic experts call for 35 dB(a) maximum to allow residents to enjoy their property without suffering noise pollution and its side effects. In addition, experts call for limits of 50 dB(c) to protect from side effects of low frequency sound.

Investigate for Yourself:

Rob Rand, consultant in acoustics with membership in the Acoustical Society of America (ASA) and the Institute of Noise Control Engineering (INCE), prepared a report on Noise produced by wind turbines which was submitted to the Riga (MI) Township Planning Commission.  Click here to view the report: Rob Rand – Report on Turbine Noise Levels
