The City of Lafayette, Colorado, has existing noise ordinances. However, it seems that the enforcement of these ordinances is selective. Let's ask the City of Lafayette to increase their enforcement of these continuous noise ordinance violations and to create consequences for the continued non-compliance. 

This is what the existing code says:

Sec. 75-281. - Noise prohibited.
(a) It shall be unlawful for any person to make, cause to be made, or to permit any unreasonable noise upon any property within a residential, public or developing resource district or for any district within any vehicle owned, possessed or operated or controlled by such person.

(b) Law enforcement personnel, including community service officers, may, in the determination of whether a noise is unreasonable consider factors that include, but are not limited to:

(1) The time of day;

(2) The size of any gathering of persons creating or contributing to the noise;

(3) The presence or absence of sound amplification equipment; and

(4) Any other factors tending to show the magnitude and/or disruptive effect of the noise.

Regardless of the zoning district, the quiet hours are 10:00pm - 7:00am.

Although an argument can be made that this weekly noise falls under "Community Activities", there are provisions that prohibit noise that disturbs neighbors, regardless of intention.

Sec. 75-283. - Specific prohibitions.
 
(a) It shall be unlawful for any person to make, cause or permit the following, all of which shall be deemed unreasonable noise; however, the following list shall not be deemed exclusive:

(3) To play, use or permit the operation of any device for producing or reproducing sound in such a manner as to disturb the peace, quiet and comfort of the neighboring inhabitants or at any time with louder volume than is necessary for convenient hearing for any persons in the structure or vehicle in which the device is operated or in such manner as to be plainly audible from the structure or vehicle.

Despite enforcement calls from the surrounding neighborhoods each Sunday before 7am, the noise continues. The City of Lafayette and Flatirons Community Church need to be held accountable for these continuous noise violations.
