A data center sharing a lot line with a more restrictive zoning district must provide landscape screening at a rate of three shrubs per 25 linear feet of data-center property line, and street trees are required at a rate of one 2.5-inch-caliper shade tree per 50 linear feet of frontage when required by the Village Engineer. (landscape and street-tree requirements)

Existing trees at least six inches in diameter at breast height must be preserved when possible under a tree-preservation plan, and removal of such trees generally requires replacement trees at a rate of one three-inch-caliper tree per six inches of removed tree diameter, capped at three replacement trees per removed tree. (tree preservation and replacement rules)

Security fencing is required around the property at a height of eight feet, must be landscaped to meet applicable screening standards, and may not use chain-link or mesh fencing with screening slats or fabric, barbed wire, razor wire, or electrified elements. (security fencing requirements)

(submittal requirements)

Additional buildings and improvements may be constructed without further zoning review only if the owner submits site, elevation, and landscape plans and the Community Development Director determines that they comply with the development standards. (conditions for additional buildings and improvements)

Data centers in the listed zoning districts are subject to the use classifications and additional standards in the zoning code, including the requirements of Chapter 10B; special uses, where applicable, are governed through the separate special-use process. (use and additional-standard requirements)

Creates a dedicated Data Center District intended for data-center facilities and associated infrastructure, including air handlers, generators, water-cooling and storage facilities, utility substations, and other infrastructure supporting continuous operations (data center definition).

Allows data centers not only in the new DC District but also in the M-1 and I-1 industrial districts, subject to the same development standards (also will permit data centers in the M-1 and I-1 industrial zoning districts).

Permits structures up to 65 feet in height, allowing taller data-center buildings and equipment clearances (not more than sixty-five feet).

Allows up to 75 percent of a lot to be occupied by buildings, accessory structures, and impervious surfaces (no more than seventy five percent).

Allows an owner in a Planned Development to construct additional buildings and improvements without further zoning review or approval by the Village's corporate authorities, provided the owner submits site plans, elevations, and landscape plans and the Community Development Director determines that they comply with the development standards (without further zoning review or approval).
