C. The minimum requirements of this section 17-6-13 shall apply to any data center operated as a principal use unless the council waives a requirement or requirements during the specific 3 EXHIBIT A TO MARANA RESOLUTION NO. 2024-108 Amendments to Marana Town Code, Title 17 "Land Development"pursuant to Marana Ordinance No. 2024.029 plan rezoning process. In addition to these minimum requirements, the town may impose additional or more stringent site-specific requirements or regulations during the specific plan rezoning process, provided that the site-specific requirements or regulations are reasonably related to the impact of the development. D. The minimum requirements of this section shall apply to any data center operated as an accessory use only where indicated. E. The minimum requirements of this section that are based on the planned or zoned property uses of adjacent properties shall be established based on the planned or zoned uses at the time of the specific plan rezoning process. F. The provisions of this section are intended to supplement the requirements of this code.If any provision of this section is found to be in conflict with any other provision of this code, the provision that establishes the higher or more restrictive standard shall prevail. G. Noise Attenuation. The developer of a data center to be operated as either a principal or an accessory use must conduct a noise study performed by a qualified third-party acoustic engineer to document baseline sound levels in the area of the proposed data center and to produce a noise contour exhibit depicting the anticipated noise levels to be generated by the data center. 1. For purposes of this section 17-6-13: a. "dBA"means the sound pressure level in decibels as measured on a sound level meter using the A weighted filter network. The A weighted filter network is designed to simulate the response of the human ear. The A weighted sound level is expressed by the symbol "dBA." b. "Daytime" means 7:00 a.m. to 7:00 p.m. on weekdays, and 9:00 a.m. to 8:00 p.m. on Saturdays,Sundays, and legal holidays observed by the town. c. "Nighttime" means 7:00 p.m. to 7:00 a.m. on weekdays, and 8:00 p.m. to 9:00 a.m. on Saturdays,Sundays, and legal holidays observed by the town 2. Any noise which emanates from any operation, activity, or source on a data center site, including, but not limited to, heating and cooling system(s), shall not exceed the maximum permissible sound levels set forth in Table 2 (Maximum sound levels for data center operation) measured at the property line of the property affected by the noise. 4 EXHIBIT A TO MARANA RESOLUTION NO. 2024-108 Amendments to Marana Town Code, Title 17 "Land Development"pursuant to Marana Ordinance No. 2024.029 Table 2.Maximum sound levels for data center operation Pla ne r�,r A f' �r� o d pro.,y .,;" ,ir'�^,�,�r/,ty",E fir✓/A F $fi 3' a.%",�' r ,r� J�,�'" �`^' r Residential and mixed-use 55/55 Agricultural 60/55 Commercial 65/60 Industrial 72/65 3. Notwithstanding the provisions of Table 2 above, any person performing site construction work in compliance with section 11-5-4(Construction noise;extended work permits)shall not be subject to the maximum sound levels set forth in Table 2 above. 4. The data center must be designed and built to incorporate sound mitigation methods sufficient to prevent the sound levels emanating from the data center,as determined by a qualified third-party acoustic engineer, from exceeding the maximum sound levels set forth in Table 2.Design specifications for the required sound mitigation must be provided to the town before building permit approval. 5. Before issuance of a certificate of occupancy or certificate of completion,whichever occurs first,the data center operator must conduct a post-construction noise study performed by a qualified third-party acoustic engineer to document sound levels emanating from the data center measured at the property line of the nearest property to the data center property that is planned or zoned for residential land uses,or other noise sensitive use as reasonably determined by the zoning administrator, during peak operation of the data center mechanical equipment. The post-construction noise study must demonstrate that sound levels do not exceed the maximum sound levels set forth in Table 2. If sound levels exceed the maximum sound levels set forth in Table 2, the town will issue a temporary certificate of occupancy until the data center operator demonstrates that the required sound mitigation is achieved. If the data center operator is unable to demonstrate compliance with the sound levels set forth in Table 2 before expiration of the temporary certificate of occupancy,the town will not issue a permanent certificate of occupancy. 6. The data center operator must also conduct an additional noise study,as measured at the property line of the nearest property to the data center property that is planned or zoned for residential land uses, or other noise sensitive use as reasonably determined by the zoning administrator, annually during peak operation of the data center mechanical equipment for five years after completion of the initial post-construction noise study and when requested by the town thereafter.The data center operator must provide the results of the noise study to the town within 30 days of the anniversary of the date on which the certificate of occupancy or certificate of completion was issued by the town.If sound levels exceed the maximum sound levels set forth in Table 2, the data center operator shall take appropriate steps to achieve the required sound mitigation. 5 EXHIBIT A TO MARANA RESOLUTION NO. 2024-108 Amendments to Marana Town Code, Title 17 "Land Development"pursuant to Marana Ordinance No. 2024.029 H. Water. The Marana water department will not provide potable water to a data center (principal or accessory use) for its cooling system, humidity control, and other similar operations.The developer must demonstrate an alternate source of water for these operations. I. Site Design Standards. The site design standards in Table 3 (Site design standards for data center development) apply to the development of land that will accommodate data centers, as well as the placement of buildings on a given site. The standards are intended to help minimize the physical, environmental, and visual impacts of data centers on adjacent development. [REMAINDER OF THIS PAGE INTENTIONALLY LEFT BLANK] Table 3.

Solid screening walls must be constructed with a design, materials, details, and treatment compatible with those used on the nearest principal facade of a building, but may include perforated surfaces as needed for ventilation of mechanical equipment. Mechanical equipment shall be located and screened with materials that provide appropriate levels of noise attenuation to reduce sound impacts on surrounding properties. On properties adjacent to residentially zoned/planned properties, mechanical equipment must be screened on all four sides by an acoustical barrier. For purposes of this section, "acoustical barrier" is defined as an exterior solid or louvred wall containing sound-proofing materials designed to absorb noise and protect neighboring properties from noise pollution, or another effective mitigation measure specified by a qualified third-party acoustic engineer when found by the zoning 7 EXHIBIT A TO MARANA RESOLUTION NO. 2024-108 Amendments to Marana Town Code, Title 17 "Land Development"pursuant to Marana Ordinance No. 2024.029 Table 3.Site design standards for data center development administrator to provide appropriate levels of noise attenuation. Electric power lines,except electrical transmission lines carrying 48 kV or more,shall be located underground. Landscape buffers In lieu of the landscape buffer requirements in section 17-11-7(F) (Landscape buffer standards), any side or rear yard of a data center site abutting property that is planned or zoned for any use other than industrial uses shall include one of the following: • Agricultural and commercial zoned/planned properties: A minimum 50-foot buffer. This may be achieved through existing mature landscaping or a landscaped earthen berm that screens the site. Berms shall have a slope no steeper than 2:1 with a minimum height of four feet and planted with a minimum of 320 plant units*per 100 feet of right-of-way or property line. • Residential or mixed-use zoned/planned properties: A minimum 100-foot buffer.This may be achieved through existing mature landscaping or a landscaped earthen berm that screens the site. Berms shall have a slope no steeper than 2:1 with a minimum height of six feet and planted and planted with a minimum of 320 plant units* per 100 feet of right-of-way or property line. Notwithstanding the requirements of this section,use of natural topography and preservation of existing vegetation, supplemented by new vegetation,if needed,or on the outside of a six-foot-tall solid fence, may be substituted for the above requirements when found by the zoning administrator to provide visual screening from adjacent land uses at the density, depth, and height equivalent to the landscape buffer with earthen berm. To protect the landscaping and the preservation of open space, linear co-location of utilities shall not be located within the buffer. Fencing° Fencing of the property is permitted; however chain-link fencing, with or without slated inserts, and barbed wire fencing are prohibited along public or private street frontages. *See Table 4 (Plant unit equivalents) 8 EXHIBIT A TO MARANA RESOLUTION NO. 2024-108 Amendments to Marana Town Code, Title 17 "Land Development"pursuant to Marana Ordinance No. 2024.029 °Requirement applies to data centers operated as accessory uses Table 4.
