ARTICLE XX
Environmental Improvements and Energy Conservation Requirements
§ 250-196 Intent.
The environmental improvements and energy conservation requirements are designed to recognize the need for conservation of energy and natural resources and to facilitate the utilization of renewable resources. Environmental improvements are intended to moderate the effects of solar radiation, conserve energy, improve air quality, reduce glare and noise, and control erosion, largely through the planting of trees, shrubs, and other vegetative cover. Energy conservation requirements are designed to allow the installation of renewable energy devices and provide the opportunity for individuals to reduce energy dependence by encouraging the productive use of solar and wind energy components.
§ 250-197 Definitions.
The following terms are specifically defined for use within this article:
An area of land or other area used for a solar collection system used to capture solar energy, convert it to electrical energy or thermal power and supply electrical or thermal power primarily for on-site use. An accessory solar energy system consists of one or more freestanding ground, or roof-mounted solar arrays or modules, or solar related equipment and is intended to primarily reduce on-site consumption of utility power or fuels.
[Added 8-29-2022 by Ord. No. 2022-04]
A solar energy system that requires external mechanical power to move collected heat.
A mechanism for heat exchange which consists of the following basic elements: underground loops of piping; heat transfer fluid; a heat pump; an air distribution system. An opening is made in the Earth. A series of pipes are installed into the opening and connected to a heat exchange system in the building. The pipes form a closed loop and are filled with a heat transfer fluid. The fluid is circulated through the piping from the opening into the heat exchanger and back. The system functions in the same manner as the open horizontal loop system except there is no pumping of groundwater.
A borehole that extends beneath the surface. Pipes are installed with U-bends at the bottom of the borehole. The pipes are connected to the heat exchanger and heat transfer fluid is circulated through the pipes.
A landscaped barrier consisting of predominantly (80% or more) coniferous trees and shrubs, hedges, earth mounding, walls, or a combination thereof established at a minimum height of six feet. Such environmental buffer shall provide a solid visual, noise and pollutant barrier between potentially incompatible uses. Dense screen plantings shall be at least five feet in width with irregularly spaced double or triple rows of plants and shrubs to obtain a dense, solid mass.
Equipment consisting of containers, heat exchangers, piping, and other transfer mechanisms (including fluids, gases or solids), controls, and related structural support for transporting and storing collected energy (from solar energy systems), including structural elements designed for use in passive solar energy systems.
A hole drilled or bored into the earth into which piping is inserted for use in a closed vertical loop geothermal system.
An energy generating system that uses the Earth's thermal properties in conjunction with electricity to provide greater efficiency in the heating and cooling of buildings.
The effect produced by light with an intensity sufficient to cause annoyance, discomfort, or loss in visual performance and visibility.
[Added 8-29-2022 by Ord. No. 2022-04]
A durable landscaped planting area located within a vehicular use area or parking lot. Design and location shall provide shade and visual separation of parking and pedestrian areas, improve air quality, and control stormwater runoff from large paved areas. An island or strip shall be a minimum of 50 square feet in area, at least five feet in width and contain at least one shade tree, per 40 lineal feet of island or fraction thereof. Islands of 40 feet or less in length shall contain at least one shade tree. The remaining area within the island or strip shall be appropriately landscaped with grass, mulch, stones, plants, or other materials not exceeding three feet in height.

Large wind energy production facilities consist of one or more wind turbines, tower, and associated control or conversion electronics and other accessory structures and buildings including substations, electrical infrastructure, transmission lines and other appurtenant structures and facilities. A facility is considered a large wind energy production facility if it supplies electrical power principally for off-site use.
Water is pumped from a water well or other water source into a heat exchanger located in a surface building. The water drawn from the Earth is then pumped back into the ground through a different well or in some cases the same well, also known as "re-injection." Alternatively, the groundwater could be discharged to a watercourse also known as a "pump and dump." In the heating mode, cooler water is returned to the Earth, and in the cooling mode, warmer water is returned to the watercourse or well.
A solar energy system that uses natural and architectural components to collect and store energy without using any external mechanical power.
A landscaped planting consisting of trees and shrubs established at less than three feet or greater than six feet in height, so shall not interfere with any clear sight triangle. Such planting shall separate streets and vehicular use areas from parking lots, buildings, and other interior improvements. Perimeter plantings shall consist of individual trees or shrubs spaced a maximum of 50 feet apart to form a linear vegetative border, with grass or ground cover continuously thereunder.
An area of land or other area used for a solar collection system principally used to capture solar energy, convert it to electrical energy or thermal power and supply electrical or thermal power primarily for off-site use. Principal solar energy systems consist of one or more freestanding ground, or roof-mounted solar collector devices, solar-related equipment and other accessory structures and buildings including light reflectors, concentrators, and heat exchangers, substations, electrical infrastructure, transmission lines and other appurtenant structures.
