C30 Long-Term Control Plan Update/Integrated Plan
be inchided in the final list. In the event that estimated costs and durations are not defined,
Consultant will provide conceptual estimates and timelines.
With the final scoring methodology complete and all projects identified, designated City staff will
score each project to determine its raw score. Consultant will provide the City with options for
how to conduct scoring, Le, whether a City group leader should score themselves, or have a number
of staff conduct scoring and then calculate a representative score. Once raw scores are complete,
the final ranked (incorporating the criteria rankings) scores for each projects can be calculated.
This will represent the final list of ranked projects to be used for development of the
implementation schedule.
Deliverables:
® Final criteria rankings, including an Excel chart, the pair-wise comparison results, and
other associated documentation
# Final project list, including estimated costs and project life cycle duration, to be used for
the LTCP/IP scoring, optimization scheduling, and implementation
¢ Raw score and weighted scores for all projects
Task 10 ~ Scenario Development, Optimization Medel Runs, and Implementation Plan
Consultant will work with the City to develop different infrastructure implementation scenarios to
be used for the schedule optimization model and implementation plan. Possible scenarios include
I) the status quo — City’s current situation and current planned wastewater CIP based on current
regulatory compliance deadlines, 2) an unconstrained scenario with all projects (including water
treatment and water distribution projects} with no financial constraints including budgetary and
affordability constraints. The Consultant will work with the City to incorporate expenditure
scenarios into the City’s Rate Model to estimate impacts on sewer rates over the planning period.
Affordability of future rates will allow the City to demonstrate to EPA which compliance
schedules are the most affordable to the City while still meeting its regulatory obligations.
Additional scenarios relevant to the City may be discussed and evaluated.
Depending on the scenarios developed, capped annual capital outlays (i.e., funding limits) will be
incorporated into the schedule. For each scenario, Consultant will develop the schedule, a list of
projects and estimated costs to be completed within the planning period, and any projects which
are deferred to years beyond the planning period. Charts showing annual cost by project type over
time and spending limus, if applicable, will be produced as well. In addition, the benefits
distribution charts will be produced for each scenario.
Deliverables:
e® ‘Technical memorandum defining the scenarios to be used
e Optimization schedules, lists of projects to be implemented within the planning horizon,
list of deferred projects, annual costs over time charts, and benefits distribution charts for
each scenario
