San Mateo Heritage Alliance was formed in 2022 as a 501(c)3 Nonprofit Corporation in response to community concerns about losing irreplaceable historic resources and the resulting erosion of neighborhood character and sense of place that makes San Mateo the special community we call home.  We are local community leaders and volunteers.  We are your friends and your neighbors who believe that San Mateo can be a vibrant, thriving and diverse city without sacrificing its character or its heritage. 


San Mateo Heritage Alliance believes that economic growth and resource protection are not mutually exclusive, but partners in a more prosperous future.  We believe that new development that respects the contributions of the past enriches the entire community.  We believe the only way to ensure that San Mateo lives up to its General Plan 2040 vision of being a healthy, resilient, vibrant and diverse community, is to grow stronger by  identifying, protecting and preserving its irreplaceable historic resources.
