Utility District
WORKSHOP
To: Board of Directors
From: Steven Poncelet
Date: July 01, 2009
Subject: Update on the TDPUD Water Wise Demonstration Garden
1. WHY THIS MATTER IS BEFORE THE BOARD
This workshop item is a review of the draft design and bid specifications of the
TDPUD Water Wise Demonstration Garden.
2. HISTORY
Landscaping and irrigation water use are becoming increasingly important as the
District moves from a flat water rate to a new rate structure where customers pay for
the water that they use. The impact on irrigation use on water bills has been
discussed often during the Water Meter Project and during the water rate workshops.
To help customers manage their irrigation water use, and to provide 'water-wise'
alternatives, the District in FY08 began the TDPUD Water Wise Demonstration
Garden project. This garden, located at the District's main office, will include a lawn
replacement with a bunch grass/dry stream bed design, native and drought tolerant
vegetation, and water-efficient irrigation. The project include informational signage on-
site and the full garden design, plant lists, and where to source these items will be
posted on the TDPUD website.
3. NEW INFORMATION
The preliminary design of the demonstration garden and the information required to
procure the plants, materials, irrigation equipment, and installation of the garden is
complete and attached for review and comment. The attached information includes:
Sheet 1 shows a site reference which defines the four areas of the garden (Areas 1, 2,
3, & 4); Sheet 2 is a Demolition Plan to be completed prior to the installation of the
garden; Sheets 3, 4, & 5 are the Planting Plans and a Plant List is also attached;
Sheets 6, 7, & 8 are the Hardscape and Grading Plans; Sheet 9 is the Irrigation Plan
and we do plan to include a smart water controller in this project; and Sheet 10 is the
Planting Details. Not included in this package is the detailed material lists (other than
the plant lists) and the full installation specifications which will be finalized after Board
feedback and direction.
The current plan is for the District to procure the plants, materials, and irrigation
equipment as per our purchasing requirements. The installation of the garden will go
through a public works bid process and is anticipated to be brought to the Board for
approval at the regularly scheduled August 5th Board meeting.
4. FISCAL IMPACT
Sufficient funds existing within the approved FY09 budget for this project. There is no
fiscal impact associated with this workshop item.
5. RECOMMENDATION
Receive this report and provide comments and direction.
