from May 3, 2022 CIP presentation
CM Moore and Willey were nominated for the
subcommittee (July 19)
The task of the Subcommittee was to review the City Hall
facility, evaluate viable solutions and bring forward
recommendations for Council’s consideration. The review
would include options for seismic upgrades to the existing
building, renovations to the existing building, replacement
of the existing building, and other elements to support
ongoing city operations.

Project Introduction
While the focus of the reports* may vary, the findings are consistent:
•The concrete structural elements do not have sufficient ductility to resist
seismic lateral loads without sustaining significant damage. Damage to
these critical structural gravity load-resisting elements could result in
collapse of the roof structure. The life safety and economic risk could be
substantial.
•The building does not comply with either the Risk Category IV (Essential
Services Facility) or Risk Category II (regular Office Building) evaluation
criteria unless a seismic strengthening is undertaken.
* The 2021 structural report findings are similar to the findings in the 2005, 2006,
2011, 2012 and 2014 reports.
Seismic & Infrastructure Considerations
Summary
1. Seismic Upgrade of the building: will trigger some
additional work, like ADA/Accessibility improvements.
2. HVAC and other Infrastructure systems: how can you not
replace these systems that are 50+ years old?
3. Seismic + HVAC/Infrastructure + Accessibility/ADA work
will affect over 75% of the building, which leads us to
consider a full interior renovation project.
4. Essential Facility (Risk Category IV) or not (Risk
Category II)?
Seismic & Infrastructure Considerations
Scope of Work Scenarios
Summary:
It is well-documented that many structural engineers recommend that
the 1965 City Hall building be seismically retrofit. The HVAC and other
infrastructure systems are also significantly past their useful life and
require replacement. We recommend a full seismic/ structural upgrade,
as well as a complete reconstruction of all infrastructure systems such as
HVAC and life safety systems.Council can consider proceeding with
the City Hall project in Risk Category II or Risk Category IV.

EOC
Current Location (+/-1400 sq. ft.)
Summary:
On October 18, Council gave approval to proceed with
programming, design, and construction of the City Hall Annex
building as the City’s Permit Center and Emergency Operations
Center (EOC). Council can consider proceeding with the City Hall
project in Risk Category II or Risk Category IV.

Recommendations
61 seats, 9,950 sq ft 65 seats, 11,500 sq ft
21,450 sq ft with 126 seats =
170 sq ft per person
Space Programming (Interior)
Current Floor Plans
Current Staff headcount at City Hall: 130 people
Move 25 occupants to City Hall Annex = 105 occupants
(does the Annex become a permanent Permit Center?)
Accounting for Population Growth:
•10% increase: 116 people
•20% increase: 126 people
Accounting for Telework:
•Current headcount + 10% Growth – 30% WFH = 84 people
•Current headcount + 20% Growth – 20% WFH = 105 people
*** 21,450 sq. ft. / 105 people = +/- 204 sq. ft./person ***
Space Programming (Interior)
Growth Projections
Summary:
We believe the current footprint of City Hall can accommodate
the Staff, Council offices and support functions such as
community meeting rooms, planning for 20% growth and
leveraging an efficient Telework policy that allows for 20% to be
working remotely. We do not recommend the expansion of City
Hall in order to address workplace overcrowding at this time.
We recommend a full interior renovation to make better use of
the interior space.

PROPOSED PROJECTS
Parking
Proposed Parking Improvements
EXISTING CONDITIONS PROPOSED PROJECTS
Summary:
Since the pandemic has disrupted the parking patterns at Civic
Center, it is difficult to ascertain the present and future parking
needs at Civic Center. Assuming the City Hall building will not
be expanding its footprint, we recommend the immediate
implementation of new surface parking along the rear of
Community Hall (+16 spaces) , and plan for future surface
parking along the north edge of Library field (+21 spaces,
approximately).

Project Size Funding Options Considerations
Small
($7M)
Use of General Fund (GF) Fund
Unassigned Fund Balance (FB)
or General Fund Capital
Reserve
Would leave Capital Reserve in
GF and the Capital Fund intact
for additional future projects
Medium
($26M-44M)
Use of both GF Unassigned FB
and GF Capital Reserve
Would limit future CIPs
Large
(Over $45M)
Debt Financing Could wipe out several reserves
leaving only economic
uncertainty remaining should
the City require additional
funding. Limit future CIPs.

Estimates
We recommend proceeding with the Full Renovation of City Hall building
(Seismic, HVAC, IT, Interiors, etc.), budgeting $26M, as part of FY23-28 CIP.
Council can also consider upgrading to “Essential Facility” standards
($4M).
•We also recommend adding parking behind Community Hall, budgeting
$350,000 (scope and budget to be confirmed) as part of the existing $1M Civic
Center Parking project
•FY23-28 CIP proposal will include a Library Parking project, and an additional
project to plan for City Hall demobilization/mobilization requirements and
communications.
