We are excited to introduce a new way for you to actively participate in addressing flooding challenges in San Mateo County! The San Mateo County Flood and Sea Level Rise Resiliency District (OneShoreline) has partnered with ISeeChange, a platform that empowers community members like you to document and share climate change impacts in your neighborhood.

Why Your Input is Crucial:
This platform allows you to report flood events as they happen. Your contributions will play a vital role in helping OneShoreline validate flood models, identify the sources of flooding, and develop targeted solutions that reflect what’s truly happening on the ground.
How ISeeChange Works:
Simply use the app or go to the website to record flooding you witness—whether it’s a heavy rain event, high tide, or unexpected street flooding. Each report will help us illustrate the scope and frequency of flooding across San Mateo County. This data will be instrumental in advocating for effective solutions and securing resources to better protect our communities.
Building Community Together:
Beyond data collection, this platform is a space to foster connections among neighbors who share the experience of living in flood-prone areas. Explore reports from others in your neighborhood, learn about the impacts in surrounding areas, and engage with fellow residents to strengthen community bonds over shared experiences.
Get Started Today:
- Download the ISeeChange app on Google Play or Apple App Store
- Start reporting: Add your observations whenever you notice flooding in your area.
