Type: Traffic & Transportation

Fund: 610 Infrastructure Renov & Replace
Sub-Fund: 100 General Fund Assets
Project Coordinator: Jack Witthaus
This project provides the replacement of computer/radio controlled irrigation equipment on City medians and roadside landscape areas throughout the City. Normally, the replacement of cabinets,
controllers and software should be done at an average interval of 15 years. In FY 2002/03, the first group of 74 controllers and four weather stations were planned to be replaced. Due to the
economic situation, only the system software was upgraded in FY 2003/04 and some of the damaged cabinets were replaced in FY 2004/05. In FY 2007/08 there was a marked increase in failure of
the units. The date for the replacement has been moved up two years to compensate. The replacement will be completed over a two-year period in FY 2010/11 and FY 2011/12 and will include 50
satellite controllers, 4 weather stations, 19 flow meters and the centralized software. Over a five year period beginning in FY 2016/17, six to eight satellite controllers will be replaced per year.
Replacement of the controllers will begin in FY 2026/27.
After this installation of the missing flow sensors, the costs for installation and replacement of sensors and controllers will be incorporated in the operating budget for Roadside and Right-of-Way
Services.
Project Evaluation and Analysis
The manufacturer has discontinued the models currently in use and is no longer providing support for them. The satellite controllers are failing and the repair costs in both labor and materials have
accelerated. In some cases the units are not repairable and have been placed offline. Repair and replacement of equipment will save wasted water, reduce the need for emergency repairs, and
improve the reliability of the system. The replacement schedule will be evaluated and will be extended as necessary.
Fiscal Impact
This project is funded by the General Fund.
