Non-Response Follow-Up

Wave 1: Cover letter to survey recipients
PASSCODE
Dear Seacoast Resident:
We are conducting an important survey, titled “Adapting to Coastal Hazards," about new programs related
to coastal hazards, including storms and flooding, in your region. Even if you are not familiar with coastal
hazards or even if you do not live by the water or in New Hampshire, your help is essential to ensure
that the survey results are as complete and accurate as possible.
The purpose of this survey is to collect information policy makers will use to make decisions about these
new programs. This survey will ask about your experiences and opinions related to coastal hazards and
options for managing shorelines in New Hampshire. It should take 20 minutes of your time.
Your address was randomly selected to receive this survey as part of a regional sample of households. We
invite the person in your household aged 18 years or older with the next upcoming birthday to complete
the survey. Please go to https://tinyurl.com/NHCoastalHazards and enter the Access Code printed at the
top right of this letter to enter the online survey.
We need your opinions. We cannot send this survey to everyone, so your answers will represent the
opinions of other residents in your region who are similar to you and your household. Your responses to
this survey will help inform policy decisions. Please take the time to read the information in this survey
and answer the questions carefully.
All answers to the survey will be kept anonymous. Your name is not associated with your survey in any
way, so that your responses can never be traced back to you. Of course, your participation is voluntary.
We have sent $2 to all potential participants who have been contacted to request their participation in this
study as a token of our appreciation. You may keep this money regardless of whether you choose to participate
in the study or not. Thank you for your assistance in this project. We would greatly appreciate if you could
complete the survey in the next week.

Sincerely,
