Using Translation

The County of San Mateo has added a translation feature developed by Google Translate to assist web visitors in understanding information on this website in a variety of foreign languages. Please be aware that Google Translate, a free third party service which the County does not control, provides automated computer translations that may not give you an exact translation. The County cannot guarantee the accuracy of translations through Google Translate so translations should not be considered exact and only used as a rough guide. Anyone relying on information obtained from Google Translate does so at his or her own risk. The County disclaims and will not accept any liability for damages or losses of any kind caused by the use of the Google Translate feature.

We are very excited about supporting our County’s diverse students and communities to be a part of the collective efforts that ensure a healthy and prosperous environment and future for all. We love empowering the youth because we believe every student has the potential to make a difference in this world. When it comes to embracing our duty as a responsible citizen of the earth, no act is too small because the small actions of many can make all the difference in the world. Our work will continue to build a community that embraces our youth’s voices and vision for a stronger, healthier, and more sustainable present and future.
