Understanding
The Fort Bragg Municipal Improvement District
(MID) wants to develop a wastewater collection
system master plan to understand and plan its future
capital improvement and anticipated system capacity
needs. Part of this effort will include evaluation of
existing information, development of data to support
the master planning effort, completing various studies
to further understand how the collection system
is functioning, and developing risk-based capital
improvement priorities and budgets that optimize
MID’s infrastructure investment while maintaining
desired service levels and reliability for its customers and stakeholders. The existing system (Figure E-1)
is mostly composed of older infrastructure that
is reaching or is beyond its anticipated useful life
Figure E-1 - City of Fort Bragg Sewer System
We have already developed the collection system geographic information system (GIS) data layers and built the preliminary hydraulic model; therefore, we can hit the ground running and continue our master planning focus that we have established with the City’s water distribution system master plan.

and requires strategic investment for renewal and
replacement. In addition, there are large undeveloped
properties within MID. While there is little anticipated growth in the short term, it will be important to
understand the current capacity of the existing
system, the potential expansion considerations in
the future, and how they relate to National Pollutant
Discharge Elimination System (NPDES) permits. Key
objectives for this study include:
• Measure and characterize collection system I&I
issues through a flow monitoring study.
• Identify, inspect, and characterize the condition
of critical areas of the collection system through
closed-circuit television (CCTV) and visual
inspection.
Section E - Scope of Work
City of Fort Bragg | Wastewater Collection System Master Plan, WWP-00021 E-2 23-10238744
• Support the City’s on-going discussions and
negotiations with River Watch.
• Understand MID’s collection system vulnerability
to potential seismic activity in the area.
• Characterize geotechnical and climate change
factors and their impact on capital planning.
• Develop a capital planning process that MID can
sustain into the future.
• Identify and update essential data, analysis tools,
models, and spatial information to support ongoing
and future planning.
• Coordination with the water and sewer line
extension projects in the industrial area north of
Pudding Creek.
Approach
As we’ve demonstrated on the ongoing water
distribution system master plan for the City, we
firmly believe in the importance of a collaborative
partnership between the consultant and client,
capitalizing on the synergy between your local
expertise and our national experience. To make sure
that the project meets the City’s expectations in
terms of analysis depth and breadth, we propose a
combination of project status meetings and follow-up
meetings after key task deliverables. This approach
keeps the project team well informed throughout
the planning process, actively engaged in significant
decisions, and make sure there are no unexpected
surprises upon report delivery.
Our project approach also places a strong
emphasis on the synergy between our project
team’s substantial experience in similar collection
system planning projects and your team’s in-depth
institutional knowledge of your system’s requirements
and overarching challenges. Our extensive track
record in executing collection system master plans
nationwide will be instrumental in providing valuable
insights to the City.
We recently converted the City’s AutoCAD files
for the utility system (water, sewer, and storm) and
we are in the process of developing a wastewater
system hydraulic model, which gives our team a
unique understanding of the City’s collection system.
Combined with our recent water demand projection
work, there is an efficiency that directly relates to
our team developing the sewer master plan. There is
simply no learning curve for the HDR team as many of
the water master plan elements can apply directly to
the sewer master plan (for example, mapping, growth
projections, and risk modeling).
We understand that the City’s expects this master
planning effort to produce preliminary engineering
reports (PER) for funding applications. Our detailed
PERs and the 10% design approach will offer the
necessary level of detail for a seamless transition of
key recommended projects from the planning phase
to facilitate funding application and support initiation of project designs after the master plan is finished.
Based on our understanding of your project goals
and objectives, our team has developed a proven
approach on the following key elements detailed in
Figure E-2 on the following page.
Hit the Ground Running for Flow
Monitoring
Securing meaningful flow monitoring data in 2023
is not assured due to the timing of procurement;
however, our team’s approach gives the City the best
chance of capturing adequate wet weather data this
wet season (2023/2024). We have conducted a
thorough assessment of the collection system and
identified potential flow monitoring locations. With
V&A as part of our team, we can seamlessly share
this valuable information to make sure an expedited
start.
Our approach to flow monitoring is to perform
site reconnaissance for each of our proposed sites
to assess site access and site hydraulics. We will
then adjust sites, as necessary, install meters, but
not activate them until we see wet weather events
approaching. Once we determine we are in an
appropriate wet weather period and have a high
probability of collecting good wet weather event data,
we will activate our meters and begin the monitoring
period. We will also monitor wet weather events
as the end of our monitoring period approaches to
determine if it makes sense to leave meters in place
if there is a high probability that a significant rainfall event can be captured. This approach has been used
successfully on previous flow monitoring efforts to
support sewer master plans.

Section E - Scope of Work
City of Fort Bragg | Wastewater Collection System Master Plan, WWP-00021 23-10238744 E-5
Scope of Work
Task 1 – Data Collection and Modeling
Subtask 1.1 – Field Survey
HDR’s subconsultant will survey collection system
manholes to assist in the calibration of the collection hydraulic model. Survey locations and actual effort
will be identified based on review of the current
hydraulic model to improve accuracy. Existing
survey information will be used to the greatest extent
possible.
DELIVERABLES:
• Survey data: Raw data points and processed data.
ASSUMPTIONS:
• This task is budgeted with up to 10 days of field
surveying.
• Traffic control is not included in this budget.
Subtask 1.2 – Flow Monitoring
A wet weather flow monitoring of the collection
system will involve the installation, operation, and
data analysis of flow monitoring equipment within
the specified system to characterize I&I issues within
the collection system. Findings from this effort will
be used for input into the hydraulic model and to help
prioritize capital improvement projects. This task will encompass the following:
• Site assessment and verification of proposed
monitoring locations
• Installation of flow meters and data loggers.
• Calibration and validation of monitoring
equipment.
• Continuous data collection over an eight-week
period.
• Real-time data transmission.
• Routine equipment maintenance.
• Data analysis to identify flow patterns and
anomalies.
HDR will:
• Establish the baseline sanitary sewer flow at the
flow monitoring sites.
• Estimate available sewer capacity.
• Isolate I&I response and perform I&I analysis.
ASSUMPTIONS:
• Flow monitoring schedule is assumed to be eight
weeks.
• Eight flow monitoring locations and two rain
gauges are assumed for this study. The final
number, locations, and duration to be determined
with input from City. A budget adjustment may
be necessary to accommodate final monitoring
parameters.
• Note that selected sites may need to be moved
if local conditions are not suitable for monitoring
(e.g. manhole depths greater than 30 feet, elevated
gas levels that cannot be cleared with forced
ventilation)
• Traffic control will be provided by MID where
needed.
• Encroachment permits or other municipal permits
are not needed or will be acquired by MID.
• Other items not included are:
° Shutdowns, dewatering, or cleaning of structures
° Excavations
° Entry into manholes greater than 30 feet in
depth
° Supplied air for conditions where it is unsafe due
to atmospheric conditions
° Tasks associated with this effort may be subject
to prevailing wage rate requirements. An
allowance has been made for this, however the
final requirements may impact the planned
budget
Subtask 1.3 – Calibrate Hydraulic Model
HDR will incorporate field survey data and flow
monitoring data collected from the previous tasks
Section E - Scope of Work
City of Fort Bragg | Wastewater Collection System Master Plan, WWP-00021 E-6 23-10238744
into the hydraulic model for calibration and model
refinement.
ASSUMPTIONS:
• Up to 40 hours are budgeted for model calibration.
Additional effort may require a fee adjustment.
DELIVERABLES:
• Updated modeling/mapping of sewer collection
system network.
Subtask 1.4 – Preliminary Risk Analysis &
Identify Closed-Circuit Television (CCTV)
Target Area
HDR will perform a preliminary risk analysis to
identify CCTV target areas. This will be a desktop
study that assigns a risk score to each pipe based on
preliminary risk factors determines with MID. I&I
findings will also be incorporated to identify the best locations to televise pipe. The proposed locations for
CCTV inspection will be documented in an Inspection
Plan and will be reviewed and confirmed with MID
prior to initiation.
DELIVERABLES:
• Final only CCTV Inspection Plan.
Subtask 1.5 – CCTV Inspection (Optional)
It is recommended that a partial CCTV be performed
but is not required for a developing an adequate
capital plan. This task is for optional inspection
of up to 3 miles of the City’s gravity mains to
get a representative sample of the system’s. We
have established a budget based on $4 per lineal
foot, which includes cleaning and inspection and
characterizing the defects. This unit price does not
include:
1. Traffic control
2. Root cutting
3. Reverse setups
4. Cost of water
5. Disposal
DELIVERABLES:
• CCTV inspection video in digital format.
• PACP database with operational and structural
defects coded.
Subtask 1.6 – Identification of Gravity Pipe
Improvements
Once the CCTV inspection has been completed, HDR
will evaluate the results to identify improvements to
the collection system gravity pipes. HDR proposes
to use decision support modeling software (e.g.
Innovyze InfoAsset Planner, Aquanuity AquaTwin
Asset) to develop the risk model and decision
logic for identifying rehabilitation and replacement
recommendations. This software works with the
existing GIS and CCTV data to assign a risk score
for each pipe and identify the desired renewal
recommendation based on decision logic and
planning-level cost information. HDR will use their
in-house version of the software so there is no need
for MID to purchase it, however, the modeling results
will be provided for future use. The risk modeling will assign a risk score to each pipe based on likelihood
and consequence of failure factors established with
MID. In addition, a capital improvement decision
model will be developed that identifies the best
option for renewal based on MID established decision
criteria and expected cost information. This will
generate a prioritized list of capital improvement
and reinspection recommendations for the entire
collection system. MID can use this list to determine
the investment vs risk level that best meets their
needs.
To develop these models, HDR will work with MID
to determine the required criteria. HDR will conduct
two workshops with MID to develop the risk model,
and one workshop to determine the renewal decision
logic. Once this is established, HDR will calibrate
and run the models and review the results with MID.
We will validate the results by reviewing individual
recommendations with the City toto establish that
they are appropriate and adjust the model if needed.
This will provide a prioritized list of recommendations for the gravity pipelines.
DELIVERABLES:
• Integrated gravity sewer decision support model
results.
• Risk and capital improvement recommendations
incorporated into GIS.
Section E - Scope of Work
City of Fort Bragg | Wastewater Collection System Master Plan, WWP-00021 23-10238744 E-7
• Draft and final technical Memo summarizing field
assessment.
• Recommendations for gravity pipe reinspection.
• Plan for an on-going condition assessment cycle.
ASSUMPTIONS:
• Six, two-hour virtual workshops will be conducted
with the City.
• Sufficient information will be available to
determine sewer main installation dates. If not
available, MID will advise on the appropriate
approach to identify pipe age.
• Current construction costs (past three years) of
rehabilitation projects will be used to forecast
program costs, if available.
• Where rehabilitation method costs are not
available, HDR will utilize professional experience
to develop costs.
• Escalation factors for future years will be based on
Engineering Consumer Price Index (CPI).
Subtask 1.7 – Visual Assessment of Lift Stations
HDR will perform a visual assessment of the six lift
stations, which are part of the collection system. The
visual assessment will be performed over two-day
sites tour with City staff. The gathered information
will be used to augment desktop-based assessment
of the lift stations to memorialize the condition of the lift stations. During the site tour, the City will share any known issues and background information about
the lift stations to help plan for existing deficiencies.
To prioritize capital improvement recommendations
generated from the visual assessment, HDR will
develop a desktop risk assessment to assign a risk
score to each station. This will be based on available
data including available flow data, lift station location and position in the collection system. Each station
will receive a risk score which will be considered in for prioritization of recommended improvements.
ASSUMPTIONS:
• A minimum of two City staff familiar with the lift
stations shall accompany HDR staff on the site
tours. HDR will interview the two City staff during
the tours.
• This task is based on a visual assessment and staff
interviews by two HDR staff members: a process
engineer and an electrical engineer.
• This task does not include any budget for
performance or destructive testing, or structural
analysis.
DELIVERABLES:
• Write-up section in the overall field assessment
TM.
Subtask 1.8 – Priority and Timing for Renewal of
Force Mains
HDR will identify priority and timing for renewal of
force mains. A substantial portion of the City’s force
mains is comprised of Techite pipe. Techite is a failure prone material, which often ruptures catastrophically.
It usually does not exhibit visual evidence of imminent failure; therefore, there is no reliable field assessment to assess condition. This task will be a desktop-based
assessment to evaluate the force mains, identify
rehabilitation or replacement options, and determine
priority and timing for renewal.
HDR will perform a desktop-based assessment to
evaluate the network of force main, which is Techite,
then evaluate priority and timing for renewal of the
force mains.
DELIVERABLES:
• Write-up section in the overall field assessment
technical memo
Task 2 – Analyzing Environmental
Variables
Subtask 2.1 - Existing and Future Capacity
Planning and Planning for Capacity Deficiencies
HDR will determine the current system’s capacity and
estimate future capacity needs using data collected
during and before the preliminary evaluation phase.
HDR will use the experience gained from the water
distribution system master plan to gain efficiencies
in the developing criteria to evaluate existing system
capacity and needs. Once the baseline capacity is
established, HDR will collect and analyze available
planning/development data or reports to estimate
future capacity requirements. After future capacity
requirements are quantified, HDR will work with
Section E - Scope of Work
City of Fort Bragg | Wastewater Collection System Master Plan, WWP-00021 E-8 23-10238744
the City to develop projects to plan for mitigating
potential capacity deficiencies.
DELIVERABLES:
• Draft and final TM in PDF format summarizing
capacity analysis.
Subtask 2.2 – Climate Resiliency Assessment
To gain efficiencies - prior to starting this task -
HDR will review the climate resiliency assessment
performed for the distribution system master
plan and solicit City’s input to better focus this
assessment. HDR will review the Fort Bragg Municipal
Improvement District’s (MID’s) General Plan (inland
and coastal) Element 7 Safety and other Emergency
Contingency Planning documents provided by the
City.
HDR will evaluate how anticipated climate change
impacts risks and vulnerabilities of the wastewater
system and consider disaster mitigation strategies
and other environmental factors impacting the MID’s
wastewater resiliency planning. HDR will evaluate the
following factors:
• Current risks from precipitation and runoff, tides
including storm surge, tsunami, coastal bluff
erosion, and fire.
• Impacts of climate change, including increased
precipitation and runoff, sea level rise on tidal
elevations, coastal bluff erosion, groundwater
increases, and increases in extreme heat and fire
risk.
HDR will document the results of the findings in a TM.
The TM will include the system’s vulnerabilities to
climate change for two planning horizons: anticipated
to be 2050 and 2070. The goal of the analysis will be
to identify changes in risks to the system in light of
climate change, such that projects can be identified
within the master plan to align with long-term climate
resilience goals.
HDR will attend one workshop/call with the City to
discuss the climate risks and vulnerabilities that have been identified.
DELIVERABLES:
• Draft and final TM in PDF format summarizing
climate resiliency assessment.
ASSUMPTIONS:
• The City will provide general plan and emergency
contingency planning documents to review within
20 days of notice to proceed.
• Up to 3 HDR staff will attend one remote meeting
up to 2 hours in length with the City to discuss the
climate risks and vulnerabilities.
• Adaptation strategies and cost estimates will not
be developed as part of this scope.
• The evaluation will be developed based on publicly
available data and data provided by the City.
Numerical models will not be developed as part of
the climate assessment.
• One round of revisions.
Subtask 2.3 – Desktop Geotechnical
Assessment
To gain efficiencies - prior to starting this task - HDR will review the geotechnical assessment performed
for the distribution system master plan and solicit
City’s input to better focus this assessment. As
part of this task, HDR will review publicly available
information on historic seismic data, review published
flood maps, and records of historical pipe repairs.
The desktop assessment will help identify areas of
concern related to geotechnically sensitive areas
and environmental factors. Additional testing may
be performed for quantitative analysis of soils. Soils
testing is not included in HDR’s scope.
DELIVERABLES:
• Draft and final TM in PDF format summarizing
desktop geotechnical assessment.
Subtask 2.4 – I&I Analysis
Following the flow monitoring activities, an analysis
of the data will be completed to provide a Flow
Monitoring and I&I analysis final report. Key activities to complete this task are:
Data reduction to 15-minute intervals. The data set
will include the following information:
• Average dry weather flows.
• Rain data from installed rain gauges and Weather
Underground Public Weather Stations.
Section E - Scope of Work
City of Fort Bragg | Wastewater Collection System Master Plan, WWP-00021 23-10238744 E-9
• Flow data (level, velocity, and flow).
• Baseline flow data.
• Daily flows (average, maximum, and minimum).
• Daily rain at each flow meter location.
The flow monitoring report will include the following
information:
• A summary of the flow monitoring equipment
used.

identifier number, flow channel condition, site
schematics, and photographs.
• Flow monitoring data with tabular outputs of
depth, velocity, and flow rate and hydrographs of
depth, velocity, and flow rates for each flow meter.
• I&I Analysis: Average dry weather flows curves will
be determined, and rain-dependent.
• Infiltration and inflow (RDI/I) response will
be isolated during wet weather rainfall events.
Analysis will include developing synthetic I&I
hydrographs for each flow monitoring site and
applying the synthetic hydrographs to a 10-year,
24-hour design storm.
DELIVERABLES:
• Draft and final TM in PDF format summarizing I&I
analysis.
• Flow monitoring data in spreadsheet format.
Task 3 – Capital Project Planning
Subtask 3.1 – Project Risk Analysis
Once the individual asset-specific analyses have
been completed and capacity recommendations
have been identified, HDR will prioritize the results
in preparation for development of the CIP. HDR
will conduct a two-hour workshop MID to develop
a prioritization approach that incorporates the
condition-based needs and capacity needs for the
various types of infrastructure studied. This approach
will leverage the risk modeling completed in previous
tasks and assign a project prioritization score to
each recommendation. HDR will conduct another
two-hour workshop to review the results and get
additional input from MID. The results can then be
uses to guide the sequencing of capital work.
DELIVERABLES:
• Workshop minutes in electronic format.
• Project prioritization scoring factors and results.
• Draft and final TM in PDF format summarizing the
prioritization analysis and results.
• Prioritization scoring factors and scores for each
recommendation.
ASSUMPTIONS:
• Two two-hour workshops are budgeted under this
task.
• Up to two HDR team members will attend each
in-person workshop. Other team members may
participate via web-conference.
• City staff will be readily available and able to
participate.
Subtask 3.2 – Project Packaging
Once the prioritization is completed, HDR will
evaluate the results to determine how to package
the recommendations into projects. Many of
the recommendations will be too small to be
completed as single project and will need to be
packaged together into larger efforts to be cost
efficient. HDR will develop an initial packaging of
the recommendations and review the results with
MID in a two-hour workshop to obtain comments
and feedback. The packaging will use the existing
risk analyses, and project prioritization scores to
determine sequencing.
DELIVERABLES:
• Workshop minutes in electronic format.
• Draft and final CIP project packages, including
project data and documented packaging strategy.
ASSUMPTIONS:
• Four (two-hour) in-person workshops are
budgeted under this task.
Section E - Scope of Work
City of Fort Bragg | Wastewater Collection System Master Plan, WWP-00021 E-10 23-10238744
• Up to two HDR team members will attend each
workshop.
Subtask 3.3 – Identify Funding Opportunities
HDR will identify project funding opportunities and
funding streams. To gain efficiencies - prior to starting this task - HDR will review funding opportunities
developed for the water distribution system master
plan and solicit City’s input to better focus this effort.
Our team will identify ideas to make the most of
available funding while lessening federal compliance
requirements. This will help reduce overall project
costs and administrative requirements. Under this
task, potential funding sources will be explored
include:
• State Revolving Fund (SRF)
• Department of Water Resources (DWR)
• United States Department of Agriculture (USDA)
• Water Infrastructure and Finance Innovation Act
(WIFIA)
Task 4 – Collection System Master
Plan
Subtask 4.1 – Develop Capital Improvement
Plan
The results for this task will be documented in the
project planning report. This report will be provided to the City for review and comment.
The report will include a 10-year capital improvement
program (CIP). The CIP recommendations will
be prioritized based on project prioritization
and packaging performed in Task 3. The
recommendations will be categorized to identify
actions to take immediate action (e.g. withing the
next two years, in the near-term (within the next five
years) and long-term (five to ten years).
HDR will develop the CIP considering resource and
funding constraints and overall CIP funding strategies
or policies that MID requires.
The sequencing will incorporate inflation and
escalation to capture future cost increases.
HDR will conduct a workshop with the City to
review the report and discuss the comments. The
results of this workshop and comment review will be
incorporated into the final version of the report.
DELIVERABLES:
• Draft and final Project Planning Report in PDF
format.
