I n 2015, C apital P rojects initiated an evaluation of the Moraga and O rinda C rossroads P umping S tations
at the reques t of O perations due to several def iciencies with the standby generator systems, electrical and
instrumentation c oncerns, and other equipment identif ied f or near term replacement. T he most impactf ul

item identif ied was replacement of the 1,000-horse power Waukesha dies el engines (circa 1959) at both
stations. S taf f hired V. W. Housen and A ss oc iates (V W HA ) to assist in the project and prepared a bas is
of design report with options to replace the engines and other station improvements.
C oncurrently, the C omprehensive Wastewater Master P lan identif ied several structural, mechanical,
electrical, and ins trumentation improvements needed at the Martinez, F airview, Maltby, and F lush K leen
pumping stations . T hese stations have multiple concerns, including reliability of existing equipment and
inf rastructure, c orrosion, are prone to f looding, and have some pumping c apacity limitations. C entral S an
staf f decided to package these stations with Moraga and O rinda C rossroads to f orm one all-
encompassing improvement project, which has been included in the current C apital I mprovements B udget
titled P ump S tation Upgrades P roject, D is tric t P roject 8436.
S taf f sought a s ingle engineering consultant to coordinate and prepare the predesign work and continue
design servic es based on the recommendations provided, while f ocusing on the most critical elements
identif ied in the project.
T he improvements identif ied and included in this project are aimed at addressing the f ollowing drivers :
P roviding long-term reliable wet weather pumping;
P rovide f irm pumping capacity at all pumping stations;
R eplac e and upgrade the emergency backup power systems;
R eplac e or rehabilitation of the electric al, instrumentation, and controls at all pump stations;
S af ety improvements and implementing recommendations f rom the A rc-F lash S tudy completed in
2015;
E quipment replacements (f low meters , variable f requency drives, automatic transf er switches, and
others);
R eplac ing deteriorating piping, gates , valves, and structures and provide long-term corrosion
protection; and
P roviding resiliency f rom f looding.
C entral S an s taf f prepared a R equest f or P roposals (R F P ) and it was advertised f rom May 22, 2017 to
J une 19, 2017 on P lanetB ids to select a prof essional engineering consultant to provide design serves f or
the project. T he design services included are preliminary services (up to 30% design) and detailed f inal
design servic es (to 100%). T hree proposals were received; C arollo E ngineers, I nc., S tantec C onsulting
S ervices (MW H), and V W HA . S taf f evaluated the proposals and interviewed the consultant teams.
V W HA had the highest total score and is c ons idered the best overall f it f or the project.
S taf f recommends V W HA in association with HD R , I nc. and A rc S ine E ngineering f or the design of the
P ump S tation Upgrades project. T he scope of work f or the consultant agreement will include, but is not
limited to, the f ollowing:
A n “all elec tric” evaluation f or the Moraga and O rinda C rossroads P ump S tations that includes
replacing the existing wet weather dies el driven engines at each station with electric variable speed
pumping;
A n asses s ment f or the six pump stations f or corrosion, structural, elec trical, instrumentation and
controls ;
A n asses s ment of the C oncord Main Metering S tation f or corrosion, s tructural, electrical,
instrumentation and controls;
A high-level evaluation to determine the s cope of improvements and planning level construction c os t
to poss ibly eliminate the F airview P ump S tation;
A n inves tigation of the six pump station s ites to identif y the f lood ris k potential based on existing
conditions , proposed conditions, and s ea level rise;

strategy inc luding procurement considerations and project design pac kage recommendations,
phasing plan(s), and preliminary (30%) design drawings.
S taf f has evaluated this action and concluded it is exempt f rom the C alif ornia E nvironmental Q uality A c t
(C E Q A ) under C entral S an C E Q A G uidelines S ection 15262 since the agreement would be used f or
design studies f or possible f uture actions whic h C entral S an has not approved, adopted, or f unded, and
the outcome of these tasks will not have a legally binding ef f ect on later ac tivities. A pproval of this action
will establish the B oard of D irectors’ independent f inding that the action is exempt f rom C E Q A . T he B oard
f urther f inds that C entral S an will produce appropriate C E Q A complianc e documentation prior to
undertaking any "project" arising f rom these design studies.

A n alternative would be not to package all the pump stations to be designed by one consultant and
perf orm the projects individually with separate contracts, which is not rec ommended. T he goal of the
predesign work is to f inalize the scope of work, construction constraints, determine any special
requirements , develop a realistic schedule, and cost estimates. I n addition, this ef f ort will determine how to
package and s equence the construction phas e.
F inal design is not included in the V W HA agreement at this stage. S taf f intends to negotiate a f inal des ign
f ee with V W HA af ter the predesign work is c omplete and provide an update and seek f urther approval of
the design at a f uture B oard Meeting. T he budget f or f inal design is planned f or the project in F iscal Year
(F Y) 2018-19.

T he V W HA predesign services is expected to reach $780,000. T his projec t is included in the F Y 2017-18
C apital I mprovement B udget on page 131 with a total estimated F Y 2017-18 budget of $850,000,
including staf f time.
T he total estimated project cost is $33,435,000, which includes $450,000 f or planning (F Y 2016-17),
$2,596,000 f or design (staf f and consultant work in F Y 2017-19), and $30,389,000 f or construction (F Y
2019-22). T he agreement f or V W HA may reach up to $2,300,000 if all the project elements are
completed, whic h is 7.5 percent compared to the total estimated construc tion costs.
