C. Firm’s Experience & References
The following references highlight some of the similar research we have conducted recently on behalf of
other clients. In these projects, we have served as a committed and responsive member of the team. All
of the projects were completed on time and on budget.
City of Davis
Reference: Mike Webb | Title: City Manager, City Manager’s Office
Phone: (530) 757-5602 | Email: mwebb@cityofdavis.org
EMC Research worked with the City of Davis in 2019 to understand resident satisfaction, explore
preferred methods of communication about Davis news and events, and test support for renewing the
City's existing 1% sales tax. The sales tax was renewed on the March 2020 ballot with nearly 83%
support. In 2022 the city once again turned to EMC Research to provide updated research about
resident satisfaction and perceptions around public safety. EMC again worked with Davis in 2023 as the
city contemplated a potential ballot measure, and a 1 cent sales tax was approved with 64% support on
the November 2024 ballot.
City of Sonoma
Reference: David Guhin | Title: City Manager
Phone: (707) 933-2213 | Email: dguhin@sonomacity.org
In April 2024, EMC conducted a multimodal survey of likely November 2024 voters in the City of Sonoma
regarding a potential sales tax measure. Survey topics around general tax sensitivity, support for the
proposed sales tax measure, perceived importance of components, and both positive and negative
messaging themes helped inform the City Council that a measure was feasible, and a priority for a
majority of City voters. Measure T was placed on the November 2024 ballot and passed with 58.5%
support.
City of Capitola
Reference: Jamie Goldstein| Title: City Manager
Phone: (831) 475-7300 | Email: jgoldstein@ci.capitola.ca.u
In January 2024, EMC conducted a multi-modal survey of likely November 2024 voters in the City of
Capitola regarding a potential sales tax measure. The survey examined voters' attitudes towards City
government, general tax sensitivity, support for a potential sales tax measure, perceived importance of
measure components, and the impact of information, as well as viability for a potential GO bond. Survey
findings helped the city make assumptions about a sales tax measure’s feasibility and also informed
changes to the measure language and structure. Measure Y was placed on the November 2024 ballot
and passed with 67.5% support.
EMC Response to RFP #CM_2025_03 -9-
D. Methodology & Project Understanding
EMC will conduct a comprehensive assessment of the City’s budget, infrastructure needs, and
community priorities to identify viable revenue measure options. Our approach includes designing and
executing statistically valid multilingual surveys to gauge community support, analyzing optimal election
timing, and providing data-driven recommendations. The findings, along with strategic insights and
actionable recommendations, will be presented in a detailed final report to key stakeholders.
Part 1 – Public Opinion Survey
For this research, we recommend conducting a mixed-mode survey of 400 voters in the City of Diamond
Bar. A sample size of 400 completed interviews, which corresponds to a margin of error of plus or minus
4.9 percentage points at the 95% confidence interval, will yield results that are generalizable to the
voter population in the City, and allow us to provide analysis and recommendations to the City on the
best election cycle for a potential revenue ballot measure, considering voter engagements, and
community priorities. The survey will likely average 15-18 minutes in length to provide in-depth,
actionable feedback from voters. Interviews, including both live telephone and online, will be offered in
multiple languages to ensure representativeness, including English, Chinese (Mandarin), and Korean
languages.
This approach ensures representativeness and inclusiveness by reaching voters in multiple ways: by
phone, by email and by text message. Voters reached by phone will take the survey with a live
interviewer, while those reached by text or email will be invited to complete the survey online. We take
multiple steps to ensure that our survey samples are demographically representative of voters, lending
validity and reliability to the results. The sampling procedures will be consistent with generally
recognized, scientifically valid sampling techniques designed to produce a survey reflective of the voter
population.
After reviewing the City’s culture, current budget, Capital Improvement program, and infrastructure
needs, EMC will designs a questionnaire to assess the needs and opinions of the public, highlight
community support for specific projects and services, preferred revenue measures, the impact on
revenue based on survey responses and determine community interests related to potential ballot
measures. Our survey questionnaires are not cookie-cutter. We will work with you to develop a survey
that capitalizes on our expertise while addressing your specific challenges. For example, we can design
the survey to test more than one revenue mechanism (such as type of ballot measure or monetary
amount) and also test messaging in favor of and opposed to the proposed ballot measures to gauge any
weaknesses or areas that may require public education or outreach. We will not begin any data
collection until all parties are satisfied with the final survey instrument.
Challenges/Research Options
A significant challenge to the City’s stated research objectives would be to gather reliable feedback
about multiple ballot measures and various tax rates within a single poll. To prevent order effects (for
example, registering a false positive when asking about a lower tax amount after asking about a higher
one), EMC would typically recommend split-sample methodology whereby respondents would be
randomly assigned to be asked about one option or another, rather than both (or multiple) options.
While this helps prevent order effects, there are tradeoffs - it could compromise data reliability, as
splitting the sample of 400 respondents would significantly reduce the sample size for each subset,
thereby lowering the confidence level of the results within each split sample. One solution is to increase
the overall sample size to 500 interviews, the maximum we believe is feasible in the jurisdiction.
EMC Response to RFP #CM_2025_03 -10-
However, the each split would still only be 250n and have a margin of error of 6.2 percentage points. An
alternative would be to use a follow-up tracking survey to refine measure type or amount after getting
preliminary results from the baseline survey. Both options are provided below in our pricing section.
Part II – Communications and Reporting
We understand public agencies and the sensitivity of working for the public. Before issuing the final
report, we will meet with City staff to review the draft report and recommendations to be presented to
the City Council. The Consultant will present data and recommendations to the City Council at a regular
City Council meeting determined by City staff.
Part III - Additional Tasks
Following the initial baseline poll, we will work with you to determine additional research if needed.
Depending on the results and timing of the baseline survey, it may be prudent to plan for a tracking
survey to be conducted close to the deadline for placing a measure on the ballot to aid in making a final
“go/no-go” decision. This tracking survey would likely be shorter and more focused on testing the level
of support for an agreed upon measure (with language that is refined based on the results of the
baseline survey) and testing key messages that may aid in voter comprehension surrounding the
measure.
The methodology for a tracking survey would mirror that of the baseline with a sample size of 300 likely
voters, and we anticipate an average questionnaire length of 12 minutes. EMC would discuss the pros
and cons of the tracking survey option with the client and consultant team and make a recommendation
about the usefulness of this component as the time approaches.
In summary, for this project, EMC will complete the following:
• Develop final research design in consultation with the client;
• Design a survey questionnaire in consultation with the client;
o Deliverable: final poll questionnaire
• Translate the survey into Chinese (Mandarin and Korean);
• Collect survey data through interviews conducted by telephone from a central telephone bank,
supervised by an on-duty supervisor;
• Adapt the questionnaire for online application; program and host the survey using professional
survey software; manage the deployment of survey invitations via text and email; and collect
survey responses online;
• Monitor data collection daily to ensure the process is going according to plan, and adjust
strategies as-needed to ensure a representative sample of the City’s voter universe;
• Tabulate, code, clean, and weight the survey data from both modes;
o Deliverable: topline poll results
• Perform in-depth analysis of the data;
• Produce cross-tabulations of voter responses based on key demographic information, such as
but not limited to City Council District, ethnicity, age, homeownership status, etc.;
o Deliverable: crosstabs
• Prepare a report of results with charts, analysis, and recommendations;
o Deliverable: detailed report, including graphic presentation of key findings, analysis and
recommendations, provided electronically for distribution
