CC Regular Session 7. 1. Meeting Date: 05/13/2014 By: Chris Anderson, Community Development Information Title: Consider Ordinance # 14-04 Amending City Code to Establish Minimum Standards for Alternative Energy Systems Purpose/Background: The City was recently approached by Connexus Energy about a potential solar project they are considering implementing on their campus. In reviewing their project concept, it was noted that City Code is fairly silent regarding solar energy systems, other than two basic definitions related to solar energy and solar access. Also, within City Code, there is a provision that states uses that are neither specifically permitted or denied in any zoning district shall be considered prohibited. As alternative/renewable energy technologies continue to improve, Staff wanted to ensure that the Zoning Code itself was not a barrier to potential alternative energy projects and thus has compiled a draft ordinance for consideration. Note that Wind Energy Conversion Systems (WECS) standards already exist and this draft ordinance does not address them other than renumbering and revising/relocating the purpose statement. Notification: A Notice of Public Hearing was published in the Anoka County UnionHerald, the official newspaper of the City. Observations/Alternatives: In Reviewing the Comprehensive Plan, Chapter 5 (Land Use) Section D (Solar Access Protection) states that the City should be encouraging the use of solar energy in future development projects as well as exploring opportunities to increase the usage of solar energy systems in general. With these policy statements in mind, Staff contemplated several standards that could be considered relating to alternative energy systems (solar and ground source heat pump systems), including, among other things, whether they should be a permitted or conditional use, their location on a property (front, side, and/or rear yard), setbacks, height, and visibility/screening. As drafted, the proposed ordinance identifies both solar energy systems and ground source heat pump systems as a permitted accessory use in any zoning district. These systems generally do not present the same concerns that had been raised regarding WECS, such as safety and noise and therefore, allowing these systems as a permitted accessory use seems more appropriate. The proposed ordinance addresses three (3) primary standards including location of an alternative energy system, setbacks, and height. The intent again was to develop minimum standards such that the Zoning Ordinance did not create a barrier to a property owner interested in implementing either a solar or ground source heat pump energy system. Thus, rather than restricting the location of these systems to certain locations on a property (e.g. side/rear yard), the proposed ordinance initially allowed solar and ground source heat pump systems to be located in any yard, whether in a commercial or residential district. Setbacks were also developed with flexibility in mind and are based on the type of alternative energy system. Solar energy systems are broken into two categories, ground mounted and building mounted systems. Building mounted systems shall comply with all standard building setbacks for the applicable zoning district. Furthermore, any system that extends beyond the edge of building must be explicitly engineered for such use. As initially drafted, ground mounted systems were to be setback from a property line a distance that is equal to or greater than the height of the structure at its maximum designed tilt.
