Plant Operations/Maintenance/Maintenance Engineering
ISSUE: On August 7, 1998, sealed bids were received and opened for construction of the Sludge
Blending Tank Overflow Drain Realignment Project, DP 6123. The Board of Directors must authorize
award of the contract or reject bids within 30 days of the bid opening. Board authorization is required
for contingency allocations of more than $25,000.
BACKGROUND: The primary and secondary sludge is blended and stored in two tanks. The overflows
from these tanks enter a drainage system, which also serves the basement of the new Maintenance
and Reliability Center (MARC). The drainage system is not adequate to handle sludge overflows
without causing possible overflows in the MARC basement drains. This project will re-route the
overflows from the sludge tanks to a drainage system with adequate capacity.
Plans and specifications were prepared by Plant Operations Department. The Engineer's Estimate for
the construction cost was $60,000. The project was advertised on July 13 and July 29, 1998. Six
bids, ranging from a low of $63,764 to a high of $76,546, were received and publicly opened on
August 7, 1998. A summary of these bids is shown in Attachment 2. The Purchasing Section
conducted a commercial evaluation, and the Plant Operations Department conducted a technical
evaluation of these bids, and they have determined that NV Heathorn, Incorporated, is the lowest
responsible bidder with a bid amount of $63,764.
The allocation of funds required to complete this project, as shown in Attachment 3, is $75,000. The
total estimated project cost is $100,000. This project was not included in the fiscal year 1998-99
Capital Improvement Budget (CIB). Staff has conducted a cash flow evaluation of the Sewer
Construction Fund and concluded that adequate funds are available for this project.

AUTHORIZE THE GENERAL MANAGER-CHIEF ENGINEER TO ALLOCATE $75,000 FROM THE
TREATMENT PLANT PROGRAM CONTINGENCY ACCOUNT FOR THE CONSTRUCTION
Staff has also concluded that this project is exempt from the California Environmental Quality Act
(CECA) under District CECA Guidelines Section 18.2, since it involves repair and maintenance of an
existing public facility with no increase in capacity. Approval of this project will establish the Board
of Directors' independent finding that this project is exempt from CECA.
RECOMMENDATION: Authorize award of a construction contract in the amount of $63,764 for the
construction of the Sludge Blending Tank Overflow Drain Realignment Project (DP 6123) to NV
Heathorn, Incorporated, the lowest responsible bidder. Authorize the General Manager-Chief Engineer
to allocate $75,000 from the Treatment Plant Program Contingency Account for DP 6123.

AUTHORIZE $35,000 FROM THE COu.ECTlON SYSTEM CONTINGENCY ACCOUNT FOR
IMPROVEMENTS TO THE LANDSCAPING AT THE SAN RAMON (LARWIN) PUMPING
STATION (DP 6128)
SUBMITTED BY
John C. Pearl, Plant Maintenance Div. Mgr.
INITIAllNG DEPTJDlV
Plant Operations Department/Maintenance Division
ISSUE: Authorization by the Board of Directors is required for allocations from the Collection System
Program Contingency Account in amounts greater than $25,000.
BACKGROUND: The existing landscaping at the San Ramon Pumping Station has been in place for
more than 22 years. In response to direction from the Board of Directors, a phased plan has been
designed to improve the overall appearance of the property, with the focus of the work being on the
east, or street side. The common theme is to tone down the institutional appearance of the site, while
maintaining the necessary security for the Pumping Station's facilities.
An allocation of $35,000 is requested to cover the cost of this work, which will provide improvements
in the overall appearance of the facility.
The work is presently planned to be done in four phases and includes replacement of the front fencing
and gates with an ornamental iron fence and gate, which will be more attractive, while allowing the
public and law enforcement to see into the station compound. Planters and walkway improvements
are being considered to present a softer, less industrial appearance.
Additional work will be done on the driveway, replacing the asphalt with interlocking pavers and
constructing the interior paths with a similar material. Again, the effect will be to make the site blend
in with the rest of the community. The front plants, which are junipers, will be broken up with large
boulders and additional planting, reducing the bareness and providing a unified theme from one end of
the property to the other. Additional perennial plants will be added.
The work is planned to take advantage of existing landscaping features, which is the most cost-
effective approach, and which will meld with upcoming maintenance work at the Pumping Station.
We continue to maintain the landscaping currently in place, utilizing both District and specialty
contractor services.

SAN RAMON LANDSCAPING
. i
Initial planning and design work done in fall of 1994
Cost estimate approximately $31,000
Focus was on interior, or inside the fence line
Rejected as capital project
Have since maintained some money in the Pumping Stations budget for work
Neighbor issues:
Junipers are old-fashioned landscaping
Junipers are a fire hazard - take them out
Trees "shed" pollen/seeds on others' property
Eucalyptus trees may be a fire hazard
Location near high school:
Loitering
Debris, garbage
Minor vandalism
Present focus is on the front, or general appearance of the station, as seen from the street
Working with landscape contractor maintaining Plant grounds
Work scope includes:
Upgraded fencing, with sight lines into compound
Replace asphalt driveway with interlocking pavers
Installing three interior planters
Replace old, non-functioning irrigation system
Install 25,000 pounds of moss rock boulders in specific locations in front
Adding flagstone paths in interior (210 square feet)
Plant additional perennials in front
Move signage now on gate to interior structure
Build screen/shelter in front of main transformer
Add "river rock" set in concrete in strategic locations
My estimate: $35,000
Station painting:
Repaint to reduce "institutional" look - architect's recommendation
My estimate: $10,000
Other impacts:
Fuel tank replacement
Station modifications and upgrades to accommodate Dougherty Valley
