About the Event

Want to help coastal communities that are experiencing repeated flooding? We need volunteers to help map the extent of high tides in Hampton, NH during this fall’s King Tide (Sunday Oct. 27 – Wednesday Oct 30). What’s a King Tide? It’s one of the highest tides of the year, and many streets and neighborhoods in Hampton will be flooded. The community of Hampton is partnering with NH Sea Grant and UNH Extension to learn exactly how high and where the flooding is. Results will help Hampton – and other coastal areas – prepare for future flooding.

If you are available to volunteer in Hampton, NH during some part of Oct. 27-30 (timing is flexible), you are invited to attend a training on Monday, Sept. 30, 6:30 – 8:00 pm at the Masonic Temple in Hampton, NH. You’ll get trained on smart phone-based mapping techniques using the Sea Level Rise mobile app. No experience necessary.


  • Access to a smart phone (yours or come with a partner who has one) and ability to download the Sea Level Rise app here (free). Or you can find it on the App Store for iOS devices or Google Play for Android.
  • Willingness to work independently for at least 2 hours surveying and mapping the extent of coastal flooding in the town of Hampton, NH. Volunteering will take place outdoors during the fall 2019 King Tide (Sun 10/27 – Wed. 10/30), with hours and timing flexible.
