Discussion and Review of Tiffin Municipal Code Revisions – Preparation for Setting the Public Hearing — Tiffin City Code - DRAFT

CHAPTER 165 ZONING REGULATIONS other elements within the City. When well designed and properly installed, exterior lighting can be and is very useful in improving visibility and safety, providing a sense of security, and complementing the character of the City. If exterior lighting is not well designed and properly installed it can be inefficient, cause glare, and create light trespass and sky glow. Light trespass falling over property lines can illuminate adjacent grounds or buildings in an objectionable manner. In order to insure that exterior lighting is well designed, and impacts on adjacent properties are limited, the following requirements are set forth controlling exterior lighting in both residential and non-residential zoning districts. 2. Regulations. All public and private exterior lighting must be in conformance with the requirements as specifically established by this Zoning Code and in general, exterior lighting is shaded or inwardly directed so that no direct lighting is cast upon adjacent zoning lots and adequate exterior lighting, for security purposes, is required for parking areas. 3. Procedure. A. Lighting Plan Required. A lighting plan is required for all non- residential uses in residential zoning districts, multiple family developments other than duplexes, commercial, industrial, institutional, and public uses including uses developed by other units of local government. At the time any exterior lighting is installed or substantially modified, a lighting plan must be submitted to the Planning and Zoning Commission in order to determine whether the requirements of this section have been met. A lighting plan is required for all special uses and planned area developments. Where a lighting plan is required, the plan shall include the following: (1) A site plan showing pole locations, building mounted lights, bollard lights with schematic wiring layout and power source connection; (2) Specifications for luminaries and lamp types, poles, wiring, conduit, and appurtenant construction including photographs or drawings of proposed luminaries; (3) Pole, luminaries, and foundation details including pole height, height of building mounted lights, mounting height, and height of the luminaries; (4) Elevations of the site including buildings, luminaries, and other structures sufficient to determine the total cutoff angle of all luminaries and their relationship to abutting parcels; (5) Lamp wattage of all luminaries proposed; (6) Photometric plans that show the foot candle (horizontal measurement internal to the site and at the property lines and the foot candle) vertical measurement at the property lines only. (Foot candle - horizontal measurements are taken along a horizontal plane at a height of three and one-half feet above the ground. Foot-candle - vertical measurement is taken at a minimum height of three and one- half feet above the ground but shall also be required at any height along a vertical plane at a property boundary pursuant to the direction CODE OF ORDINANCES, TIFFIN, IOWA - 1493 -
