SUBJECT
CONDUCT PUBLIC HEARING, CONSIDER ADOPTION OF NEGATIVE
DECLARATION, AND CONSIDER APPROVAL OF THE PROJECT FOR NORTH
CONCORD/CLYDE SEWAGE COLLECTION SYSTEM IMPROVEMENTS PROJECT
INITIATING DEPT./DIV.
TYPE OF ACTION
CONDUCT PUBLIC HEARING
ADOPT NEGATIVE DECLARA-
TION AND APPROVE PROJECT
SUBMITTED BY
JAC UELINE L. ZAYAC PLANNING GRANTS TECH.
ENGINEERING DEPARTMENT PANNING DIVISION
ISSUE: A publ ic hearing must be conducted prior to adopting the Negative
Declaration for the proposed North Concord/Clyde Sewage Collection System
Improvements Proj ect, herei nafter call ed "the proj ect." If the Negative
Declaration is adopted, approval of the project is required.
BACKGROUND: The California Environmental Quality Act (CEQA) and guidelines
require the Board to consider the Initial Study prepared and publ ic comments
received pri or to approv i ng the Negative Decl arati on for the proj ect. If the
Board adopts the Negative Declaration, approval of the project will be required
to complete the CEQA requirements and allow the District to file a Notice of
Determination in the County Clerk's office.
The Initial Study for the project was prepared by Earth Metrics, Inc., an
environmental and planning consulting firm. District staff concluded that the
Initial Study for the project adequately, accurately, and objectively evaluated
the proposed project's effect on the environment. Based on the Initial Study, it
was determined that a Negative Declaration is the appropriate document for the
proj ect.
In compl iance with the CEQA requirements, District staff arranged for a legal
notice to be publ ished which sol icited comments and provided notice of the
District's intent to adopt the Negative Declaration for the proposed project.
The project, located in Watershed 44, includes a portion of North Concord, the
unincorporated town of Clyde, a portion of the United States Naval Weapons
Station, and unincorporated land east and south of Mallard Reservoir as shown on
Attachment 1.
District flow capacity studies indicate that pump station and collection system
improvements are needed in the immediate future to meet exi sting and projected
demands from approved and anticipated land developments. The present system has
difficulty accommodating existing peak flows during storm periods, and District
staff has determi ned that the proposed improvements are needed to accommodate
ongoi ng development. Benefits from the proposed proj ect woul d .. resul t from
reduci ng the number of pump stati ons from four to two. These benefits i ncl ude
the conservation of energy, chemicals, labor, and maintenance expenses.

to all future projects in this sensitive area of the District. Therefore, it is
appropriate to hold a public hearing on Mr. Monaco's project.
Staff will notify all resi dents who woul d be affected by the annexati on and sewer
extension that a hearing will be hel d to receive input fran the public. Provided
that no significant environnental issues are brought to 1 ight at the hearing,
staff will proceed with the categorical exemption and the processing of the
annexati on.
RECOMMENDATION: Establish September 19, 1985, as the date for a public hearing
regarding 1) the annexation of the Monaco parcel (Lake Orinda Highlands Area, and
2) the extension of the public sewer on La Madronal to service said parcel.

SUBMITTED BY INITIATING DEPT./DIV.
JARRED MIYAMOTO-MILLS, ASSOCIATE ENGINEER ENGINEERING DEPARTMENT/ENGINEERING DIVISION
ISSUE: Board authorization of funds is required for predesign and design of
Concord Industrial Pump Station Upgrading, District Project No. 4091, in the
North Concord/Clyde area of Watershed 44.
BACKGROUND: Capacity analysis of collection system facl1ities in the North
Concord/Clyde area (Watershed 44) has recently been completed by District staff.
The capacity analysis identified needed capital improvements required for
continued adequate service. The proposed North Concord/Clyde Collection System
Improvements Project, as a whole, is the subject of a public hearing to consider
adoption of a Negative Declaration on this evening's agenda. Upgrading of the
Concord Industrial Pump Station from 120 gallons per minute to approximately
1,100 gallons per minute rated capacity is one element of the proposed project.
Thi s proj ect e1 ement consi sts of rep1 acement of pump motors, improvement of
electrical and control systems, and construction of additional wet well capacity.
The proposed pump station upgrading is shown in context with the other project
elements required in Watershed 44 on Attachments 1 and 2.
It is estimated that $21,000 will be needed to complete predesign and design of
the pump station upgrading project element. A breakdown of this total is
provided in Attachment 3. All engineering work will be done by District staff.
The authorization being requested includes a previous $5,000 authorization by the
General Manager-Chief Engineer to initiate predesign work. This project is
included in the Five-Year Capital Improvement Plan. The preliminary construction
cost estimate is $60,000.
RECOMMENDATION: Authorize $21,000 from the Sewer Construction Fund for predesign
and design of Concord Industrial Pump Station Upgrading, District Project
No. 4091.

ISSUE: An agreement needs to be executed and the job started before September 1,
1985 in order to complete the above work before the upcoming wet season. Attachment
1 of this position paper is a map of the damaged areas.
BACKGROUND: A landslide caused by creek erosion located adjacent to a District sewer
line occurred at the above location during the 1982-83 storm season. The slide has
enlarged each year since then causing a break in the sewer line and threatening the
property owner's house and additional sections of the District's line. The
geotechnical studies conclude that the best solution to the erosion problem is a
complete restoration and stabilization of the creek bank below the house. The
District's line has to be placed within this bank since no practical alternative
routing is available.
In addition to the landslide, the 1982-1983 storm season caused erosion at one
support of the creek crossing located just downstream of the landslide, resulting in
sagging and cracking of the sewer pipeline. After evaluation of several
alternatives, it was determined that the most econanical repair is to replace the
damaged support, protect the slopes around the creek crossing, and replace the
damaged portion of sewer pipeline.
Negotiations were conducted with the haneowner, Robert Wootten, and his insurance
carrier, SAFECO. An agreement has been reached to repai r and stabilize the creek
bank, protect the house, and replace the District's sewer line. SAFECO has agreed to
pay $80,000 toward this with the District covering the remaining expenses. The final
cost is not known at this time but is expected to be around $160,000 including
engineering design, construction, and inspection. In addition, this estimate
includes the work required to repair a storm damaged District sewer creek crossing
which is also located on the Wootten's property. It would be desirable to have all
the construction activity to be done at the same time. A breakdown of the estimated
costs is presented in Attachment 2 to this position paper.
SAFECO is obtaining bids for the work and when a better cost estimate can be made the
staff will return to the Board with a request for Sewer Construction Funds. This is
anticipated to be ready for the September 5 meeting.
The geotechnical analyses by both the District's and SAFECO's engineering consultants
indicate that there is a significant probability that the District's line, the

Wootten's house, and the creek crossing trestle could be lost during a severe storm
this fall or winter if the repairs are not completed in time. If this occurs there
woul d be a public health risk because of raw sewage spilling into the creek which
flows into the East Bay Municipal Utility District's San Pablo Reservoir. The
District would thereby incur an increased liability from local, state, and federal
regulatory agencies. Because of these extraordinary risks the staff recommends that
the District Board declare that an emergency situation exists pursuant to Public
Contract Code Section 20806 so that the work can be initiated as soon as the
necessary agreements are signed.
RECOMMENDATION: Authorize the GM-CE to execute an agreement with SAFECO and Robert
Wootten for renovation work at #12 Evergreen Drive, Orinda, to repair the creek bank
and sewer creek crossi ng, and to restore the Di stri ct' s permanent sewer li ne.
Decl are that an emergency situation exists at 112 Evergreen Drive, Orinda, under
Public Contract Code Section 20806.
