HomeMy WebLinkAboutGlenshire Drive Pipeline Memorandum
To: Board of Directors
From: Neil Kaufman, Water Systems Engineer
Date: May 20, 2002
Subject: Surveying for Glenshire Drive Pipeline West of the Glenshire Drive
Bridge
BACKGROUND:
As a result of the acquisition of Glenshire Mutual water system, it is necessary to
construct a pipeline to provide additional water supply to the Glenshire area. For
design purposes, the pipeline has been broken into three parts.
GLENSHIRE DRIVE WELL TO THE GLENSHIRE DRIVE BRIDGE
As discussed at the Board meeting on May 15, a favored alignment has been
identified. I had originally contacted Mike Sullivan of Sierra Nevada Civil
Engineers (SNCE) to perform the necessary survey work for the design. SNCE
performed the surveying for development of the tentative and final maps in this
area. Upon further discussion with Mr. Sullivan, it was determined that he is too
busy with other work and could not commit to performing the necessary work in a
time frame to meet the District's needs.
I then contacted Andregg Inc. and requested a proposal to expand the survey
work currently being performed along Glenshire Drive to cover the entire pipeline
alignment. Andregg has indicated that the work can be performed in a timely
manner with delivery of the mapping expected towards the end of June into early
July.
GLENSHIRE BRIDGE-TRUCKEE RIVER CROSSING
Dokken Engineering is currently working on the design of the pipeline across the
bridge under a contract previously approved by the Board.
GLENSHIRE DRIVE BRIDGE TO THE GLENSHIRE SUBDIVISION
As approved at the Board Meeting on May 1, Andregg is currently surveying this
portion of the alignment. I am anticipating delivery of the mapping in the middle
of June.
PERMITTING AND ENVIRONMENTAL REVIEW
Garcia and Associates has begun the environmental review for the pipeline. A
meeting is scheduled with Lahontan RWQCB for this week to perform a field walk
of the alignment. I am anticipating that the draft Initial Study will be presented to
the Board at the meeting on June 5.
PIPELINE DESIGN
I have begun some preliminary design work and specification writing for the
pipeline. I am awaiting the final survey work before I can proceed much further.
RECOMMENDATION:
The District enter into a contract with Andregg Inc. in an amount not to exceed
$25,000 for the survey work described in the attached proposal. The $25,000 is
based on the proposed amount of$22,780 plus a 10% contingency.
