A berm averaging a minimum of fifteen (15) five (5) feet in height above the adjacent average ground level with a maximum side slope of 3:1, provided that the berm shall be covered by a well-maintained all season natural ground cover and any required screening plantings shall be arranged on the outside and top of the berm.
A visually solid fence, screen wall or panel, parapet wall, or other visually solid screen that shall be constructed of materials compatible with those used in the exterior construction of the principal building.

G. Noise and Vibration [Additionally, see section 808 (Environmental Impact Statement) and 808.10 (Noise)]
The applicant shall demonstrate through a sound study from all directions of the site conducted by a third party professional acoustical expert that the sound generated by a Data Center and/or Data Center Accessory Uses during normal operations shall be limited to a maximum daytime (8:00 a.m. to 5:00 p.m. Monday-Friday) decibel level of 55 dB(A) and a maximum nighttime and weekend (5:00 p.m. to 8:00 a.m. Monday-Friday and all day Saturday and Sunday and holidays) decibel level of 45 dB(A) as measured from the property line of the use and does not exceed pre-development ambient noise levels by greater than 10 dB(A). Infrasound (sound below 20 Hz) from data centers shall be limited to 80 dB(z). Such sound study shall be conducted using Sound Level Meters described in ANSI S1.4-2104 and generally accepted methodology. A sound study shall be conducted at the following phases:
A preliminary study shall be conducted as part of the [conditional use/special exception/land development] process. The preliminary sound study shall include recommended sound reducing materials or systems as needed to meet the aforesaid sound limits.
An interim sound study shall be conducted during the building permit approval process based upon the proposed user or users of the Data Center and Data Center Accessory Uses depicted on the building plans. Any sound reducing materials or systems recommended by interim sound study shall be incorporated into the construction plans for the use.
An as-built sound study shall be conducted six months after issuance of the certificate of occupancy and prior to the final escrow release for any land development phase. An as-built sound study may also be required thereafter by the [ county or municipality]. If it is determined by the as-built sound study that there is a violation of the aforesaid noise limits, it shall be considered a violation of this Ordinance.
Maximum decibel levels specified herein shall not apply during times of power outage, however the sound studies shall also evaluate, and report anticipated decibel
