SUBJECT: ADOPT Resolution No. 200eclariiig the intention to order an assessment for the annexed
territory of the Spanish Trails subdivision to the Hillcrest Heights Geologic Hazard Abatement
District ("GHAD"), and fixing a hearing for September 16, 2008 to consider the proposed

DATE: July 22, 2008
PAGE: 2
FISCAL IMPACT:
There will be no impact to the County General Fund. Processing costs have been paid by the applicant. The
costs for any GHAD activities that occur within the boundaries of the land proposed to be annexed into the
Hillcrest Heights GHAD will be covered with revenue generated through parcel assessments for the Spanish
Trails Development. The proposed assessment of$1,567.17 for each of the 15 improved lots in the subdivision
will be considered at the assessment ballot proceeding.
REASONS FOR RECOMMENDATIONS AND BACKGROUND:
On July 22, 2008, the GHAD Board conditioned approval of the annexation of the Spanish Trails Development
into the Hillcrest Heights GHAD on subsequent approval of proposed parcel assessments to pay for GHAD
activity to prevent mitigate and abate geologic hazards within the annexed territory. The assessment will be
levied on each improved lot in the subdivision, which funding will be collected'and used in accordance with the
Hillcrest Heights GHAD Plan of Control for Spanish Trails. The proposed assessment of$1,567.17 for each of
the 15 improved lots in the subdivision is supported by a detailed Engineer's Report prepared by a registered
professional engineer certified by the State of California, and will be considered on September 16, 2008 in
accordance with Proposition 218.
CONSEQUENCES OF NEGATIVE ACTION:
The Board of Supervisors required the approval of the proposed assessment as a condition of approval for
annexation of the Spanish Trails subdivision into the Hillcrest Heights GHAD. If the GHAD Board does not
proceed with this matter, the annexation will not occur.

4. Each of the parcels identified on the Boundary Map will receive a particular and distinct
special benefit in the form of GHAD improvements and services that are over and above the
general benefits received by the general public. Specifically, in order to control the geologic
hazards within the GHAD, the GHAD may, without limitation: (a) evaluate the performance
of the natural, cut, and reconstructed slopes, the surface drainage and ditches to prevent
certain geologic hazards within he GRAD; (b) perform certain temporary and permanent
mitigation, repairs and improvement measures to prevent, mitigate, abate and control
geologic hazards within the GHAD; (c) maintain debris benches, drainage systems and
instruments such as piezometers, settlement monitors and inclinometers; (d) maintain
detention ponds; and (e) establish a reserve to fund, prevent, mitigate, abate or control
geologic hazards within the GRAD. These special benefits are described in detail in the
Hillcrest Heights GHAD Plan of Control for Spanish Trails on file with the Contra Costa
County Department of Public Works.
5. Hereafter, whenever the parcels identified on the Boundary Map are re-subdivided and a final
map is approved and filed for recording with the County Recorder, each newly created
residential lot will be assessed in the manner provided in the Engineer's Report.
6. The GHAD Board has reviewed and considered the Engineer's Report. The special benefit
derived from the CHAD by each parcel is proportionate to the entire costs of the GRAD, and
the amount of the assessment is proportional to, and no greater than, the benefits conferred

for the
ESTABLISHMENT OF AN ASSESSMENT LIMIT
I. INTRODUCTION
The Hillcrest Heights Geologic Hazard Abatement District ("GHAD or "District") was formed
under the authority of the California Public Resources Code, Division 17, Section 26500 el.seg.
II. BACKGROUND
The County of Contra Costa Board of Supervisors adopted Resolution No. 96/329 on July 23,
1996, approving the formation of the Hillcrest Heights Subdivision 7582 Geologic Hazard
Abatement District ("Hillcrest Heights GHAD"). The Board of Supervisors, acting as the Board
of Directors of the Hillcrest Heights GHAD, adopted Resolution No. 2008/ on
2008, approving the annexation of the Spanish Trails subdivision to the Hillcrest Heights
GHAD. Under Public Resources Code section 26581, the Board of Supervisors then adopted
Resolution No. 2008/ on , 2008, approving the annexation of the Spanish Trails
subdivision to the Hillcrest Heights GHAD.
III. GEOLOGIC HAZARD ABATEMENT DISTRICT BOUNDARIES
The boundaries for the Spanish Trails subdivision are shown in the diagram attached hereto as
Exhibit A.
TERRASE.ARCH,hic. Page 5 of 17
Project No.6034.63 Engineers Report/Spanish'Trails 27 May 2008
IV. SERVICE LEVELS
The Hillcrest Heights GHAD provides for activity that is necessary or incidental to the
prevention, mitigation, abatement, or control of geologic hazards including construction,
maintenance, repair, or operation of any improvement, and the issuance and servicing of bonds
issued to finance any of the foregoing.
The Hillcrest Heights GHAD provides for the administration and review of facilities within
budgeted limits and including the following services:
1. Oversight of GHAD activities.
2. In conjunction with the County Assessor's Office, setting the. annual levy ol'
assessments on the property tax rolls.
3. Retention of geotechnical professionals to perform the monitoring duties described in
the GHAD Plan Control for Spanish Trails.
4. Performance of GHAD maintenance activities in accordance with the Hillcrest
Heights GHAD Plan of Control for Spanish Trails. These maintenance activities
include:
• Lined surface drainage ditches.
.• Storm drain inlet, outfalls and pipelines within common areas.
Subdrains.
• Retaining wall and appurtenant drainage facility maintenance.
• Debris wall maintenance.
• Erosion management.
5. Slope reconstruction
6. Preparation of annual GHAD budgets.
V. DESCRIPTION OF THE GHAD IMPROVEMENTS
The GHAD improvements are described in the Hillcrest Heights GHAD Plan of Control for
Spanish Trails, dated 27 May 2008. In general, improvements include drainage systems
(including concrete v-ditches in open space, open-space storm drain inlets and outlets and
TERRASEARCH,inc.. Page 6 of 17
Project No.6034.63 Engineers Report/Spanish Trails 27 May 2008
subdrains), debris wall, retaining walls with appurtenant drainage systems, natural slopes and
reconstructed slopes and any improvements constructed by the homeowner after the builder has
constructed a house on the lot, that are accepted by the GHAD.
Vl. ASSESSMENT METHOD
The improvements referenced' in.Section V are distributed within the boundaries of the Spanish
Trails subdivision. The District Engineer hereby finds that the properties within the Spanish
Trails subdivision receive approximately equal special benefit from the work and improvements
of the Hillcrest Heights GHAD. Maintenance and protection of these improvements provide a
special benefit to all of the real property within the subdivision. As a result, the assessment is
distributed equally among all of the properties annexed to the Hillcrest Heights GHAD.
The total number of residential units within the Spanish Trails subdivision is divided into the
annual GHAD budget to develop the annual assessment amount. A financial analysis was
performed to provide a framework for an operating budget for the on-going abatement,
mitioation, prevention and control of geologic hazards within the Spanish Trails subdivision. In
preparation of the budget, several factors were considered including:
• Site geology.
• Proposed remedial grading.
• Proximity of geologic hazards to proposed residences.
• Site access considerations.
• Elements requiring routine maintenance including:
1. Surface drainage facilities
I Graded and natural slopes
3. Storm drain inlets, outfalls and pipelines within common areas
4. Retaining wall and appurtenant drainage facility maintenance
5. Debris wall maintenance
6.. Erosion management

Project No.6034.G3 Engineers Report/Spanish Trails 27 Nlay 2008
VII. ASSESSMENT LIMIT-BUDGET
Upon annexation of the Spanish Trails subdivision to the Hillcrest Heights GHAD, the District
will be funded by property tax assessments levied upon each lot within the boundaries of the
subdivision. The assessment shall be levied on each individual parcel.
Grading and construction of all improvements has been completed. The First building permit
was issued in July 2007. It is our understanding that the developer will pay $100,000 once the
GHAD improvements have been accepted or 3 years after the assessment has been confirmed,
whichever happens first.
A.summary bud(7et was prepared for the purpose of estimating initial assessment levels and is
attached as Exhibit B. In order to establish a reasonable reserve .:in the early years following
formation of the GHAD, there will be an initial deferral of GHADexpenses as described in the
Plan of Control.
Administrative Costs
The possible repair and maintenance budget costs for the Hillcrest Heights Subdivision 7582 are
unique to that subdivision and were not considered in our review. However, the administrative
costs for the Hillcrest Heights GHAD were considered relevant and are used for this .budget.
Since the Spanish Trails subdivision.will be annexed into the existing Hillcrest Heights GHAD,
the administration is in place and there will be some additional administration associated with
the Spanish Trails subdivision. It is anticipated that the additional administration costs
associated with the Spanish Trails subdivision will be lower than those currently in place for the
Hillcrest Heights Subdivision 7582. We have applied an additional administrative cost of 30%
more than the current yearly budget, as set forth below:
General Manager $5,000.00
County Public Works Personnel $1,500.00
Legal & Accounting $ 500.00
TERR FSE.t RCH,inn. Page 8 of 17
Project No.6034.63 Engineers Report/Spanish"rrails 27 May 2008
GFIAD Association Membership $7.50 (existing membership)
TOTAL YEARLY ADMINISTRATION BUDGET $7,007.50
Monitoring and Maintenance Costs
Based on the frequency of monitoring outlined in the Hillcrest Heights GHAD Plan of Control
for Spanish Trails, the cost for administrating, performing the monitoring and minor cleaning
and/or grouting and preparation of a report for one year without any major repairs is estimated to
be $8,700.per year and is itemized as follows:
I. Coordination $ 500
2. Average flour site visits per year(4 visits nw, 4 hrs/visit @ $160/hr) $ 2,560
3. Contractor(most likely required for small repair and cleaning items
At most one time per year—estimate $ 4,000
4. Follow up observation of repair/cleaning work
1 visit @ 4 hours @ $160/hr $ 640
5. Reporting $ 1.000
TOTAL YEARLY MONITORING & MAINTENANCE BUDGET $ 8,700
Major Repair(s) Costs
Major repair items will include small, moderate and large scale` soil slumps/slides, erosion,
blockage of surface and subsurface drains, damage to surface and subsurface drains and
replacement of debris fences during an unusually high rainfall period or earthquake event. The
occurrence of such events is considered to be rare, and a precise estimate cannot be made at this
time. The additional cost with such repairs could range from $8,000 to $100,000 depending on
the magnitude of the event(s), extent of damage and access. The following estimates are based
on our experience with similar size repairs that have been performed recently in the Bay Area. It
may be advisable to set up an initial fund account or increase the amount of yearly finds as a
contingency to cover any future eventualities.
TERRASEARCH,ine. Page 9 of 17
Project No.6034.G3 Engineers Report/Spanish Trails 27 Mav 2008
However, for estimating purposes, it is hypothetically assumed that one small slump will occur
every 5 years,a moderate slide (up to 50 feet by 30 feet in plan area) will occur every 10 years
and one large scale slide (at least 100 feet by 100 feet in plan area) will occur in 50 years. Once
a large scale slide is repaired the likelihood of future instabilities would decrease as a large area
of the slope would have been repaired. The total estimated cost over 50 years is summarized as
follows:
1. Repair of v-ditches and other drainage facilities
(Once every two years) 25 events a $ 2,000 $ 50,000
2. Repair of Debris Fence 6 events @ $10,000 $ 60,000
3. Small scale slumps 10 events u $ 8,000 $ 80,000
4. Moderate scale slides 5 events a $40,000 $ 200,000
'5. Large scale slide I event O $100,000 $ 100.000
TOTAL ESTIMATE $490,000
Summary of Costs
The above cost estimates are for 2008 dollars and an appropriate inflation rate of approximately
three percent (3%) should be applied. Based on 2008 dollars, the expected total .cost over the
next 50 years including total administrative costs plus total yearly monitoring and maintenance
costs.plus the total of major repairs, is estimated to be $1,275,375 (50 years x $7007.50 + 50
years x $8,700 + $490.000). Deducting the $100,000 initiallypaid into the reserve, the
remaining cost to be assessed is $1,175,375 over 50y ears. This is equivalent to $23,505.50 per
year for all 15 lots and equates to an assessment of$1,567.17 per lot per year. Accordingly, the
District Engineer recommends an annual assessment limit of$1,567.17 per residential unit to be
levied upon the completion of the annexation process. This limit will escalate annually based on
San Francisco-Oakland San Jose Consumer Price Index. Please note these estimated expenses
are only for preparing assessment levies and may not represent actual costs of actual specific
hazard occurrences or maintenance.

NOTICE OF ADOPTION OF RESOLUTION BY THE BOARD OF DIRECTORS OF
HILLCREST HEIGHTS GEOLOGIC HAZARD ABATEMENT DISTRICT
On July 23, 1996, the Contra Costa County Board of Supervisors adopted Resolution No.
96/329, approving and ordering the formation of the Hillcrest Heights Subdivision 7582
Geologic Hazard Abatement District and appointing itself to act as the Board of Directors of the
GRAD ("GHAD Board"). This formation was described in the petition dated May 8, 1996.and
in the GRAD Plan of Control dated May 8, 1996. Subsequently, the GHAD Board imposed
assessments on the properties within the CHAD to fund the improvement, monitoring and
maintenance of improvements described in the Plan of Control. These actions were taken in
accordance with Public Resources Code sections 26500 et seq. for.the purpose of the prevention,
mitigation, abatement and control of certain geologic hazards.
Due to the potential for land sliding, the Conditions of Approval for the Spanish Trails
Development (DP 03-3052, SD 02-8687) require the annexation into the existing Hillcrest
.Heights GRAD, or the creation of a new independent GRAD, prior,to issuance of the first
building permit. To satisfy these requirements, the developer of the Spanish Trails subdivision
elected to petition the Board of Directors of the Hillcrest Heights CHAD ("GHAD Board") to
annex the subdivision into that existing GHAD. The boundaries of the Spanish Trails
subdivision are not contiguous with the boundaries of the 66 unit Hillcrest Heights Subdivision
7582 that is already part of the Hillcrest Heights GHAD.
On July 22, 2008, the GHAD Board approved the annexation and adopted the Hillcrest
Heights GHAD Plan of Control for Spanish Trails. On that same day, subsequent to the GHAD
Board's approval, the Board of Supervisors approved the annexation in accordance with Public
Resources Code section 26581. Both approvals were conditioned upon subsequent approval of
the proposed assessment for the Spanish Trails subdivision.
NOTICE IS HEREBY GIVEN that:
On July 22, 2008, the GHAD Board adopted Resolution No. 2008/_ declaring its
intention to impose an assessment on the annexed property and fixing a public hearing to
consider adoption of this assessment to finance the GHAD. The total yearly estimated budget as
set forth in the attached Engineer's Report is $23,507.50. If the assessment is adopted, it is
anticipated that each parcel you own will be assessed a maximum of$1,567.17 per year, plus an
annual adjustment to reflect the percentage change in the San Francisco-Oakland-San Jose
Consumers Price Index for All Urban Consumers as of June 2008. The assessment for a parcel
will be levied beginning the first fiscal year after issuance of the building permit for that parcel.
The assessment will continue to be levied in perpetuity.
The Engineer's Report for the CHAD, attached hereto, was prepared by a registered
engineer certified in the State of California, and describes in detail the reason for the assessment
and the basis upon which the amount of the proposed assessment was calculated. The Engineer's
Report specifically sets forth the yearly estimated budget, the total assessment that will be
chargeable to the entire annexed territory, the proposed estimated assessments to be levied each
year against each parcel of property, and a description of the method used in formulating the
estimated assessment. A copy of the Engineer's Report is also available for inspection at the
office of the Department of Public Works, 255 Glacier Drive, Martinez, California 94553.
The GHAD Board will conduct a public hearing on September 16, 2008 at 9:30 a.m.
Room 107 of the Board of Supervisors' Chambers, 651 Pine Street, Martinez, California, on the
proposed assessment.
The following paragraph provides the procedures for returning and tabulating the ballots.
A copy of this Notice of Adoption of Resolution, a sealable Ballot and the Engineer's Report has
been sent to each of the property owners that were annexed to the GHAD on July 22, 2008. The
Ballot may be completed and mailed or hand delivered to Public Works Department, Attn:
Hillary Heard, 255 Glacier Drive, Martinez, California 94553, or may be submitted at the public
hearing. The Ballot may be withdrawn or changed at any time prior to'the conclusion of the
public testimony on the proposed assessment at the public hearing.
Immediately before the hearing, the Public Works Department shall tabulate the ballots.
At the hearing, the GHAD Board shall consider any objections or protests to the assessment and
certify the tabulation of the ballots. The GHAD Board shall not impose the assessment if there is
a majority protest. A majority protest exists if, upon conclusion of the hearing, ballots submitted
in opposition to the assessment exceed the ballots submitted in favor of the assessment. In
tabulating the ballots, the ballots shall be weighted according to the proportional financial
obligation of the affected property.
Inquiries regarding the proposed assessment may be made by mail, Attn: Hillary Heard,

ESTABLISHMENT Or AN ASSESSMENT LIMIT
I. INTRODUCTION
The Ilillerest IIeights Geologic IIazatd Abatement District ("GHAD or "District") was formed
Mulder the authority of the California Public Resources Code,Division 17,Section 26500 et seq.
Ii. BACKGROUND
The County of Contra Costa Board of Supervisors adopted Resolution No. 96/329 on July 23,
1996, approving the formation of the Hillcrest Heights Subdivision 7582 Geologic Hazard
Abatement District ("Hillcrest Heights GHAD'). The Board of Supervisors, acting as the Board
of Directors of the Hillcrest Heights GHAD, adopted Resolution No. 2008/ on ,
2008,approving the annexation of the Spanish'Trails subdivision to the Hillcrest Heights GHAD.
Under Public Resources Code section 26581, the Board of Supervisors then adopted Resolution
No. 2008/ on , 2008, approving the annexation of the Spanish Trails subdivision
to the Hillcrest Heights GHAD.
III. GEOLOGIC HAZARD ABATEMENT DISTRICT BOUNDARIES
The boundaries for the Spanish Trails subdivision are shown in the diagram attached hereto as
Exhibit A. .
TERRASEARCII,hie. _ Page 5 of 17
Project No.6634.G3 Engineers Report/Spanish'Trails 30 July 2008
IV. SERVICE LEVELS
The Hillcrest Heights GIIAD provides for activity that is necessary or incidental to the
prevention, mitigation, abatement, or control of geologic hazards including construction,
maintenance, repair, or operation of any improvement, and the issuance and servicing of bonds
issued to finance any of the foregoing.
The Hillcrest Heights GRAD provides for the administration and review of facilities within
budgeted limits and including the following services:
1. Oversight of GHAD activities.
2. In conjunction with the County Assessor's Office, setting the annual levy of
assessments on the property tax rolls.
3. Retention of geotechnical professionals to perform the monitoring duties described in
the GHAD Plan Control for Spanish Trails.
4. Performance of GHAD maintenance activities in accordance with the Hillcrest
Heights CHAD Plan of Control for Spanish 'Trails. These maintenance activities
include:
• Lined surface drainage ditches. .
• Storm drain inlet, outfalls and pipelines within common areas.
• Subdrains.
• Retaining wall and appurtenant drainage facility maintenance.
• Debris wall maintenance.
• Erosion management.
5. Slope reconstruction
6. Preparation of annual GRAD budgets.
V. DESCRIPTION OF THE GHAD IMPROVEMENTS
The GHAD improvements are described in the Hillcrest Heights GIIAD Plan of Control for
Spanish Trails, dated 27 May 2008. In general, improvements include drainage systems
7E.RRASEARCII ine. Page 6 of 17
.................
Project No.6034.63 Engineers Report/Spanish Trails 30 July 2008
(including concrete v-ditches in open space, open-space storm drain inlets and outlets and
subdrains), debris wall, retaining walls with appurtenant drainage .systems, natural slopes and
reconstructed slopes and any improvements constructed by the homeowner after the builder has
constructed a house on the lot, that are accepted by the GRAD.
V1. ASSESSMENT METHOD
The improvements referenced in Section V are distributed within the boundaries of the Spanish
Trails subdivision. The District Engineer hereby Ends that the properties within the Spanish
Trails subdivision receive approximately equal special benefit from the work and improvements
of the Hillcrest Heights GRAD. Maintenance and protection of these improvements provide a
special benefit to all of the real property within the subdivision. As a result, the assessment is
distributed equally among all of the properties annexed to the Hillcrest Heights GRAD.
The total number of residential units within the Spanish Trails subdivision is divided into the
annual GRAD budget to develop the annual assessment amount. A financial analysis was
performed to provide a framework for an operating budget for the on-going abatement,
mitigation, prevention and control of geologic hazards within the Spanish Trails subdivision. In
preparation of the budget, several factors were considered including:
• Site geology.
• Proposed remedial grading.
• Proximity of geologic hazards to proposed residences.
• Site access consideration.-,.
•. Elements requiring routine maintenance including:
1. Surface drainage facilities
2. Graded and natural slopes
3. Storm drain inlets, outfalls and pipelines within common areas
4. Retaining wall and appurtenant drainage facility maintenance
5. Debris wall maintenance
6. Erosion management
TERRASEARCH,inc. Page 7 of 17
....................... ......
Project No.6034.G3 Engineers Report/Spanish'Trails _30 July 2008
VII. ASSESSMENT LIMIT-BUDGET
Upon annexation of the Spanish Trails subdivision to the Hillcrest Heights GHAD, the District
will be funded by property tax assessments levied upon each lot within the boundaries of the
subdivision. The assessment shall be levied on each individual parcel.
Grading and construction of all improvements has been completed. The first building permit was
issued in July 2007. The GHAD improvements shall become eligible for transfer to the GHAD 5
years after the assessment has been confirmed.
A stunmary budget was prepared for the purpose of estimating initial assessment levels and is
attached as Exhibit B. In order to establish a reasonable reserve in the early years following
formation of the GHAD, there will be an initial deferral of GIIAD expenses as described in the
Plan of Control.
Administrative Costs,
The possible repair and maintenance budget costs for the Hillcrest Heights Subdivision 7582 are
unique to that subdivision and were not considered in our review.. However, the administrative
costs for the Hillcrest Heights GHAD were considered relevant and are used for this budget.
Since the Spanish Trails subdivision will be annexed into the existing Hillcrest Heights GHAD,
the administration is in place and there will be some additional administration associated with the
Spanish Trails subdivision. It is anticipated that the additional administration costs associated
with the Spanish Trails subdivision will be lower than those currently in place for the Hillcrest
Heights Subdivision 7582. We have applied an additional administrative cost of 30%more than
the current yearly budget,as set forth below:
General Manager $5,000.00
County'Public Works Personnel $1,500.00
Legal& Accounting. $ 500.00
GHAD Association Membership $7.50(existing membership)
TOTAL YEARLY ADMINISTRATION BUDGET $7,007.50
TERRASEARCH,hic. Page 8 of 17
Project No.6034.G3 _ Engineers Report/Spanish Trails 30 July 2008
Monitoring and Maintenance Costs
Based on the frequency of monitoring outlined in the 1-lillcrest Heights GRAD Plan of Control
for Spanish Trails, the cost for administrating, performing the monitoring and minor cleaning
and/or grouting and preparation of a report for one year without any major repairs is estimated to
be $8,700 per year and is itemized as follows:
1. Coordination $ 500
2. Average four site visits per year(4 visits @ 4 hrs/visit @ $160/hr) $2,560
3. Contractor(most likely required for small repair and cleaning items
At most one time per year—estimate $ 4,000
4. Follow up observation of repair/cleaning work
1 visit @ 4 hours @$160/hr $ 640
5. Reporting $ 1,000
TOTAL YEARLY MONITORING & MAINTENANCE BUDGET $ 8,700
Major Repair(s) Costs
Major repair items will include small, moderate and large scale soil slumps/slides, erosion,
blockage of surface and subsurface drains, damage to surface and subsurface drains and
replacement of debris fences during an unusually high rainfall period or earthquake event. The
occurrence of such events is considered to be rare, and a precise estimate cannot be made at this
time. The additional cost with such repairs could range from $8,000 to $100,000 depending on
the magnitude of the event(s), extent of damage and access. The following estimates are based on
our experience with similar size repairs that have been performed recently in the Bay Area. It
may be advisable to set up an initial fund account or increase the amount of yearly.funds as a
contingency to cover any future eventualities.
TERRASEARCH,ine. — — Page 9 of 17
Project No.6034.63 Engineers Report/Spanish Trails 30 July 2008
However, for estimating purposes, it is hypothetically assumed that one small slump will occur
every 5 years, a moderate slide (up to 50 feet by 30 feet in plan area) will occur every 10 years
and one large scale slide (at least 100 feet by 100 feet in plan area) will occur in 50 years. Once a
large scale slide is repaired the likelihood of future instabilities would decrease as a large area of
the slope would have been repaired. The total estimated cost over 50 years is summarized as
follows:
1. Repair of v-ditches and other drainage facilities
(Once every two years)25 events @$2,000 $ 50,000
2. Repair of Debris Fence 6 events @ $10,000 $ 60,000
3. Small scale slumps 10 events 8,000 $ 80,000
4. Moderate scale slides 5 events @$40,000 S200,000
5. Large scale slide 1 event @$100,000 S 100,000
TOTAL ESTIMATE $490,000
Summary of Costs
The above cost estimates are for 2008 dollars and an appropriate inflation rate of approximately
three percent (3%) should be applied. Based on 2008 dollars, the .expected total cost over the
next 50 years including total administrative costs plus total yearly monitoring and maintenance
costs plus the total of major repairs, is estimated to be $1,275,375 (50 years x $7007.50 - 50
years x $8,700 + $490,000). The $1,275,375 cost spread over 50 years is equivalent to
$25,507.50 per year for all 15 lots and equates to an assessment of $1,700.50per lot per year.
Accordingly, the District Engineer recommends an annual assessment limit of $1,700.50 per
residential unit to be levied upon the completion of the annexation process. This limit will
escalate annually based on San Francisco-Oakland San Jose Consumer Price Index. Please note
these,estimated expenses are only for preparing assessment levies and may not represent actual
costs of actual specific hazard occurrences or maintenance.
