ISSUE: An easement must be obtained for the installation of a 27-inch trunk
sewer in the Southern Pac1fic Railroad right of way at Berrellesa Street in
Ma rti nez.
BACKGROUND: The 27-inch sewer is part of the system that will replace an existing
18-inch trunk sewer which is over capacity and subject to overflows at peak flow
periods. The new sewer system will be installed during 1989. This agreement
provides Central Contra Costa Sanitary District with rights to install the
repl acement sanitary sewer across the Southern Pacific Rail road ri ght of way, a
distance of 100 feet.

ISSUE: A portion of minor Subdivision 67-87 is being dedicated to the County for
public road purposes and the widening of the private road known as Brodia Way. An
existing public sewer easement is located within the dedicated area.
BACKGROOND: The County requi res a "Consent to Dedication" whenever an area
dedicated for publ ic road purposes encroaches upon an existing easement. A
standard consent document will be used in which the District retains prior rights.
Th i s proj ect has been eval uated by staff and determi ned to be exempt frOOl the
California Environmental Quality Act (CEQA) under District CEQA Guidelines Section
18.6, since it involves a minor alteration in land use limitations.

ISSUE: All work has been completed on the Emergency Slide Repair Project at No.
I2EVergreen Drive in Or1nda (oP 4000) and all litigation and/or claims action
has been resolved; therefore, this project can now be closed out.
BACKGROUND: The contractor, W & W Construction, compl eted all work on th1 s
project on December 20, 1985, and the Board of D1 rectors accepted the work on
January 16, 1986. On June 19, 1986, the Board of Directors authorized $85,646 in
additional funding to cover the additional cost of construction on this emergency
time and materials project, including potential future legal costs. Project
close out was not initiated at that time since the contractor was involved with
litigation between the State Department of Industrial Relations <prevailing wage
issues) as well as at least one of the vendors which supplied material for the
project. Staff advised the Board that project close out would proceed only after
all remaining legal issues had been resolved.
The State of California, Department of Industrial Relations, subsequently
released the $6,225 being held for penalties for the contractor's failure to pay
prevailing wages. Per court direction, these funds were dispersed to one of the
vendors <Syar Industries) to cover unpaid bllls for material furnished to the
contractor. The other vendors' claims received were flled too late to be
considered valid. The contractor ultimately went out of business.
Since all outstanding claims and litigation have been resolved, staff is closing
out the project account. The final project cost was $243,146 which will result
in $2,500 being returned to the Collection System Program.
RECOMMENDATIONS: This item is presented to the Board for information only. No
action is necessary.

Sl1BJECT: CAPITAL IMPROVEMENT FEE PROPOSAL FOR NON- RESIDENTIAL USES
INTRODUCTION
Staff has projected that future non - residential users will contribute
about one -third of the additional flow to District facilities anticipated
from all future users. Since this is a significant fraction of the whole
and since it is desirable that the District's commitment to equity in
fees extend to non - residential users, the current system for determining
these fees has been reviewed. This review determined that revenue
generated from the current system of capital improvement fees will not be
adequate to fund expansion of District facilities needed to serve future
non - residential users. A recommendation for a revised system of
non - residential fees is discussed below.
RACKGROUND
The District's current system of capital improvement fees for
non - residential users is based on the number and type of plumbing
fixtures to be installed in a building (fixture fees) and parcel acreage
(watershed fees). Fixture fees were first established in 1953 and were
most recently updated in 1978. The first watershed fees were established
in 1958, and the most recent watershed fee was set in 1979. The intent
of the current system was to charge appropriate connection fees based on
an easily determined estimation of wastewater flow from residential and
non - residential users.
Fixture unit counts are established based on information included
in
Chapter 4 of the Uniform Plumbing Code. Fixture counts are multiplied
by
"Fixture Multiples" (either 3 or 5) to account for differences
in
flow -per- fixture -unit between residential and two broad categories
of
non - residential use. Historically, watershed fees have been established
on the assumption that wastewater flow from non - residential uses
is
proportional to parcel acreage. Neither the current fixture fee nor
the
current watershed fee calculation differentiates between users on
the
basis of wastewater strength. Rather, both fees, using different
estimation methods, seek to differentiate between users solely on
the
basis of wastewater flow. A detailed discussion of the current
fee
system is included in Appendix A of the January 5, 1989, Fee System
Analysis report.
The Honorable Board of Directors
Page 2
February 9, 1989
Recent changes in the wastewater control industry, including regulatory
requirements for higher levels of treatment, and new state and federal
legislation /regulation governing the financing of sewerage facilities
have led to the need for capital improvement fee systems which are based
on wastewater strength as well as wastewater flow. For example,
significant future treatment plant projects will focus on expansion of
secondary treatment and solids handling facilities. The capacity
requirements and costs for these facilities are more closely related to
wastewater strength than to wastewater flow. For this reason, it is
desireable that fees established to fund these improvements be higher for
high strength users and lower for low strength users. The design of the
proposed fee system addresses both wastewater flow and strength as
elements in the determination of applicable fees.
RECOMMENDATIONS
Staff recommends that the Board of Directors adopt a new capital
improvement fee system for non - residential users. The recommended system
would charge each non - residential user the fair -share cost of sewer
capacity and would be consistent with the District's commitment to
continue a pay -as- you -go approach to project financing. Specifically,
staff recommends that the Board of Directors revise the current system of
fees to base the calculation of fees for non- residential users on their
relative equivalence with residential use. This requires:
adoption of "Residential Unit Equivalence Factors" which relates a
specific "unit -of- measure" for each non - residential user group to
residential use on the basis of both wastewater flow and strength,
and
adoption of unit fees for flow and strength to document the basis
for the "equivalence factors" and to provide for the calculation of
fees for special cases.
For each non - residential user group, staff evaluated several alternative
"units -of- measure" such as the number of square feet of floor area,
acreage of parcel, number of anticipated employees, and /or customers,
etc. Continued use of fixture unit counts for the determination of fees
for most non - residential uses is recommended since the relationship of
such counts to sewer capacity requirements is better correlated than are
similar relationships for other units -cf- measure. However, where a
better correlation exists between wastewater flow and an alternate unit
of measure, that unit of measure was used. For example, a good
correlation was discovered between the number of seats for dine -in
restaurants and flow.
The recommended equivalence factors and unit fees are summarized in
Tables 1 and 2 respectively. Some user groups listed in Table 1 have
been designated "Special Study" rather than having specific equivalence

factors prescribed. These groups either have widely varying unit flow
and /or strength between individual users within the group, have very
little data on which to base prescribed factors, or are required to be
individually studied by law. An example of the latter category is the
public schools user group, where recent legislation stemming from the San
Marcos Supreme Court decision requires the District to negotiate capital
improvement fees applicable to each new school separately. A special
study would also be done for a user in a group with prescribed
equivalence factors if requested and paid for by the affected user. This
situation would arise for large connections where the user believes its
discharge would require substantially less capacity than would be
indicated by application of the prescribed factors. Typically, a special
study will determine the estimated flow and strength for a proposed
connection. The applicable fee for that connection would then be
determined based on the unit fees listed in Table 2.
In addition to providing for assessment of fees for new buildings, the
recommended fee system would require additional fees to be paid whenever
fixture units or other applicable "units -of- measure" are added to a
building. The new fee system would also provide for adjustment of
capital improvement fees when a substantial change in use which requires
additional capacity occurs.
DISCUSSION
To assure that each future user (residential and non - residential) pays
its fair share of the costs for expansion of District facilities,
expansion costs from the District's Capital Improvement Plan have been
allocated to flow and strength. The costs for expansion of collection
system and pumping station facilities are allocated to flow only since
wastewater strength is not a factor in the design of sewers and pumping
stations. Treatment plant costs have been allocated as follows:
o Flow - The costs for expansion of the plant's pumping facilities and
pipelines are allocated to wastewater flow;
o Strength - Cost allocations for strength are divided between:
- Total Suspended Solids (TSS) - The costs for expansion of the
plant's primary and solids handling processes are allocated to
TSS; and
- Biochemical Oxygen Demand (BOD) - The costs for expansion of
the plant's secondary treatment process are allocated to BOD.
The Honorable Board of Directors
Page 4
February 9, 1989
These cost allocations are attributed to the Facilities Capacity Fee and
the Pumped Zone Surcharge as follows:
FACILITIES CAPACITY FEE
Flow
697c
Total Suspended Solids (TSS) 17%
Biochemical Oxygen Demand (BOD) 14%
100%
PUMPED ZONE SURCHARGE
Flow 100%
This cost allocation approach is the industry standard and has been
recognized as such in the State Water Resources Control Board Revenue
Program Guidelines.
The following information was developed to calculate "Residential Unit
Equivalence Factors" for non - residential uses:
o The wastewater flow for non - residential and residential uses.
o The wastewater strength of non- residential and residential uses.
Wastewater Flow: Unit flow rates for residential use were developed from
a comprehensive program of flow monitoring in the District's sewer
system, which was conducted for the Wastewater Collection System Master
Plan, October 1986. Unit flow rates for non - residential user groups were
developed from actual water consumption data for current District
customers. These non - residential unit flows were divided by the
residential unit flow to determine "flow factors" relating each user
group's "unit -of- measure" flow to a residential unit equivalence.
Wastewater Strength: As discussed above, the parameters of wastewater
strength used to differentiate beteween user groups are Total Suspended
Solids (TSS) and Biochemical Oxygen Demand (BOD). The concentrations of
TSS and BOD used are those reported in the District's Revenue Plan
Amendment, May 1986, which are based on a state -wide data base of actual
wastewater strength. (Reference: California State Water Resources
i
Control Board Revenue Program Guidelines for Wastewater Agencies,
1983.) These strength data were used to calculate "strength factors"
relating each user group's TSS and BOD to a residential unit equivalence.
Calculation of the Residential Unit Equivalence Factors: The equivalence
factors are calculated as a weighted average of the relative contribution
of the flow and strength parameters. A detailed discussion of these
calculations is presented in Attachment 1.
The Honorable Board of Directors
Page 5
February 9, 1989
Fee Comparison: A comparison of current and proposed fees for a number
of recent non - residential connections is presented in Table 3. These
comparisons indicate a wide variation in the potential impact of the
proposed fee system for different user groups. For the examples cited,
this impact varies from an increase of a negative 68 percent for some
"standard commercial" connections (an auto sales lot in this case) in
areas with high current watershed fees to an increase of 1459 percent for
a dine -in restaurant in areas with low current watershed fees. This wide
variation suggests that the current system for fee determination may
underestimate the flow capacity requirements of some connections. Also,
the impact of the proposed fee system is generally greater for those user
groups with higher than average wastewater strengths since strength
differentials are addressed in the proposed fee system and are not in the
current system.
Table 4 compares the proposed fees for the same examples cited above with
the applicable fees of other Bay Area sewering agencies. This comparison
indicates a broad range of fees for a similar connection would apply
depending on the user group and the jurisdiction in which the connection
is made.
Because of the substantial impact of the proposed fees on some of the
user groups, staff has evaluated several alternatives for mitigation of
these impacts in the near term. The following alternatives were
considered:
- Implement new system without mitigation
- "Ramped" or "stepped" increase for some or all user groups over 6 -12
months
Old fee for some or all users with
Board approval of new fees
Finance fees over 3, 5, 10 years Witt
Use requested "special studies" tc
Board policy guidelines
building permit issued prior to
a lien on property
determine fees within strict
These alternatives will be presented and discussed during the Board
workshop on the proposed non - residential fee system.
SUMMARY
A comprehensive review of the non - residential capital improvement fee
system was conducted by staff to complete the 1989 Capital Improvement
Fee Proposal. This review determined that the current fee system will
not provide adequate revenue for the expansion of facilities needed to
serve new non - residential users nor would it be equitable between
residential and non - residential groups. A recommended system for ue the
determination of non-resi dential fees was developed ach to project tf i nanci ng
District's commitment to a pay -as- you -go app
which is fair to both current and future users. The new system would
estimate wastewater flow and strength for each new user based upon actual
The Honorable Board of Directors
Page 6
February 9, 1989
data for existing similar users per the District's state- approved revenue
plan. The Facilities Capacity Fee and Pumped Zone Surcharge would charge
the new user for the capacity needed to serve it based on these flow and
strength estimates. The new system would continue the use of fixture
unit counts as the "unit -of- measure" for most user groups. A Table of
Residential Unit Equivalents relating the specific "unit -of- measure" for
each non - residential user group to residential use was developed and
recommended as the basis for the determination of fees (Table 1). The
new system would also provide for adjustment of capital improvement fees
when additional fixtures, or other applicable "units -of- measure" are
added or when a substantial change in use occurs and would require a
"special study" to determine the fees applicable to user groups where
data are limited or where special circumstances apply. A Table of Unit
Fees for Flow and Strength to document the basis for the "equivalence
factors" and to provide for the calculation of fees for these special
cases was developed (Table 2).
Because of the substantial impact of the proposed fees on some user
groups, the Board may wish to consider alternative methods to mitigate
these impacts.
Implementation of the proposed fee system will require adoption of an
ordinance which sets out the methodology for the determination of fees in
detail. This ordinance is currently being prepared by District counsel.

ATTACHMENT 1
NON- RESIDENTIAL FEE CALCULATION
It is recommended that non - residential capital improvement fees be
calculated from the generalized formula:
FEE = A x B x
where, A = the number of "fixture units" per Chapter 4 of the Uniform
Plumbing Code, or other "unit -of- measure" specified (floor
area, number of seats, etc.)
B = an "Equivalence Factor" expressed as the number of
residential units equivalent to each fixture unit or other
specified "unit -of- measure"
C = the applicable residential unit fee (Facilities Capacity Fee
or Pumped Zone Surcharge).
Fixture unit counts or other applicable "units -of- measure" (A) can be
determined from improvement plans. The applicable residential unit fees
(C) would be those established by the Board of Directors by ordinance.
To determine the third element of the formula, the "Equivalence Factor"
(B), the following information was developed:
o The wastewater flow relationship between non - residential and
residential use.
o The wastewater strength relationship between non - residential and
residential use.
o The allocation of capital improvement costs between flow and
strength parameters.
This information was developed from a variety of sources. Flow data for
existing non - residential customers is compiled annually from the water
consumption records of EBMUD and CCWD. Residential unit flows were
developed from a comprehensive program of flow monitoring in the
District's sewer system which was conducted as part of the Wastewater
Collection System Master Plan, October 1986. Strength data for different
user groups is included in the District's Revenue Plan Amendment, May
1986. These strength data are based on a state -wide data base of actual
wastewater strengths (Reference: California State Water Resources
Control Board Revenue Program Guidelines for Wastewater Agencies, April
1983, and are summarized in Table A.
Wastewater Flow Relationship: Chapter 4 and Appendices C and I of the
Uniform Plumbing Code provide information on the number of fixtures
required for, and the daily flow generated by, non-residential uses.
This information and actual water consumption data for current District
customers were used to develop average flow per fixture unit, or other
"unit -of- measure" as appropriate, for the various user groups. These
unit flows were divided by the residential unit flow to calculate "flow
factors" relating each user group's flow to a residential unit
equivalence. Since the flow monitoring for the Wastewater Collection
System Master Plan determined that the average flow per residential unit
is 200 gallons per day, an equivalence, based on flow, in the form:
Flow Factor =
Flow per Fixture Unit
Residential Flow (200 gallons /day)
was developed. These flow factors are listed in Table B.
Wastewater Strength Relationship: The parameters of wastewater strength
utilized in this analysis are total Suspended Solids (TSS) and
Biochemical Oxygen Demand (BOD). The relative concentrations of TSS and
BOD used in this analysis are those reported in the District's Revenue
Plan Amendment, May 1986. These strength data were used to calculate
"strength factors" relating each user group's TSS and BOD to a
residential unit equivalence, using the formula:
Strength Factor =
(TSS or BOD)
User Group Concentration (mg /1)
Residential Concentration (mg /1)
These strength factors are listed in Table B.
Allocation of Costs: The projected costs of capital improvements needed
to serve future users were allocated to the categories of flow, TSS, and
BOD. The allocation attributed to each category for the Facilities
Capacity Fee and the Pumped Zone Surcharge follows:
FACILITIES CAPACITY FEE
F1 ow, 69%
Total Suspended Solids (TSS) 17%
Biochemical Oxygen Demand (BOD) 14%
100%
PUMPED ZONE SURCHARGE
F1 ow 100%
Calculation of the Residential Unit Equivalence Factors: The equivalence
factors for the Facilities Capacity Fee are calculated as the
parameter - allocation- weighted average of the contribution atttributable
to each flow and strength parameter. The formula is:
Equivalence [Percent
Factor = Flow Factor /100 x [Allocation +
[to flow
(Percent TSS )
(Allocation x Strength) +
(to TSS Factor )
(Percent BOD )J
(Allocation x Strength)]
(to BOD Factor )J
The equivalence factors for the Pumped Zone Surcharge are simply the
"flow factors" discussed above.
Table C lists each user group, its specific "unit -of- measure," and the
equivalence factors for both the Facilities Capacity Fee and the Pumped
Zone Surcharge.
Worksheets for calculation of the factors for each user group are
included in Table D (19 pages).
