Built in 2016, Sperry Tower was designed to hold and hide City, County and private telecommunications equipment. The newly built tower replaced an existing water tower that was not needed for water capacity and had not been used since 2009. Instead of performing extensive and expensive repairs on the water tower it was removed and rebuilt. The telecommunications tower has a maintenance cycle of 50 years versus the water tower's maintenance cycle of 25 years.

The tower is 198 feet tall and is made up of six rings at varying heights. A total of 5,448 LED light bulbs on 185 fixtures illuminate Eagan's skyline each night from just after sunset until midnight and again from 4:00 a.m. until just before sunrise. The tower lighting has nearly limitless capabilities including an indefinite range of colors as well as dynamic features to celebrate holidays and special occasions. The approximate cost to operate the tower is $2.30 per day.

Lighting Policy

On December 19, 2017, the City Council approved the amended Sperry Tower Lighting Policy for staff implementation. The policy can be downloaded here.

Introduction

The City of Eagan has erected a telecommunications tower for the purpose of serving City, County and private telecommunications antennas providing service within the Eagan area. The tower, referenced as the Sperry Tower, was also designed to be an aesthetic enhancement to the City's skyline. The aesthetics were addressed through the architectural design of the structure and the lighting features.

The lighting features on the telecommunications tower, per Council direction, have nearly limitless capabilities. There are a total of 118 lighting fixtures on the tower; 1 fixture per panel (10' high by 5' wide), 16 panels per ring, 6 rings on the tower, plus 16 fixtures for the crown (16 pieces, varying heights at 5' widths), and each of the three legs has 2 flood lights. The base of the panel rings are at 168', 150', 132', 114', 96', and 78' above the ground elevation with an option for a future seventh ring (at 60'). The top of the crown is 187' above the ground elevation. Each fixture on the ring panels (located at top) and crown pieces (located at bottom) has 48 individual LED light bulbs and is divided into 4 zones; each with their own IP address for control. Each flood light has 12 bulbs controlled by one IP address. A total of 5,448 light bulbs are controlled by 454 separate IP addresses from one controller. The LED light bulbs have an indefinite range of colors.

The purpose of the lighting policy is to enable the Sperry Tower to provide a safe, pleasant public art display through its lighting features for the enjoyment and benefit of the Eagan community. Incorporation of the tower lighting has been included as part of the City's Policy for Public Art and Installation in City Owned or Managed Spaces.

Lighting of the Sperry Tower shall be prioritized as follows:

  1. In interest of the City of Eagan;
  2. In interest of the Eagan community;
  3. In interest of Eagan community members/representatives;
  4. A greater common interest.

The management of the lighting by City staff is an additional responsibility not addressed by position responsibilities. Available lighting options offer a wide variety of associated responsibilities, from very little to a considerable amount, at times. The following policy guidelines consider the related workload impact of staff.

At full intensity with all lights on, approximately 8,000 watts of energy would be used at a cost of $7 per day (2016). Anticipated lighting intensities and operating hours (10 minutes after sunset to midnight and 4:00 a.m. to 10 minutes before sunrise each day) would expect an approximate cost of $2.30 per day (19kW/day x $0.1158/kW). The following policy guidelines consider the related energy consumption and cost.

Objective

The Sperry Tower lighting should principally contribute to the City of Eagan, further enhancing it with a sense of place and confirming the tower as a landmark within the Minneapolis-St. Paul metropolitan area. In doing so, the lighting should:

  • Draw attention and be memorable
  • Engender a unique identity
  • Celebrate holidays and noteworthy events/accomplishments
  • Promote the integration of art with urban and architectural design
  • Encourage innovation and artistic excellence in public art

Due to the public's expectation of prudent fiscal management and the appropriate use of public facilities, it is necessary to ensure all tower lighting is based on the subsequent criteria in accordance with the aforementioned prioritization. In an effort to be transparent, the basis of the lighting color(s) or dynamic feature will be posted on social media (e.g. Twitter, Facebook, etc.). The following criteria should be evaluated to ensure the suitability of lighting for the citizens of Eagan while bearing in mind proper fiscal responsibility. The guidelines should be used as general design standards for all lighting to be implemented on the Sperry Tower.
