Why We Run This Program in National City
National City is 63% Hispanic/Latino and among the most economically impacted cities in San Diego County. Our programs here are built around transportation — youth from Central, Kimball, and Olivewood Elementary travel to Imperial Beach and Coronado for water programming, with classroom components at National City Public Library and the MLK Community Center. National City is a priority Title I partnership for our Ocean Stewards recruitment.

Volunteer Programs in National City — What You Should Know
Professional development hours and certificates of service documented for National City volunteers — employer matching and school credit supported.
Single-event cleanup volunteers from inland National City (8 miles inland from coast) participate in monthly regional cleanups without weekly obligation — flexible entry points.
Why National City Matters to Our Mission
Safe, lifeguard-coordinated instruction is non-negotiable for National City youth. Every water session runs inside flagged zones with certified coaches — parents shouldn't have to choose between access and safety.
Whether National City is on the coast or 8 miles inland inland, we treat transportation as part of the program — not an extra parents must figure out. That's how you build real access, not marketing copy.

Frequently Asked Questions — Volunteer Programs in National City
Is volunteering with Un Mar free for National City adults?+
Yes — 100% free. Orientation and training cost nothing. Un Mar pays background checks for direct-youth volunteers — typically $40–$75 elsewhere. No participation fees or gear purchases for National City volunteers.
What training do volunteers receive?+
Free volunteer orientation, cultural competency training for direct-youth roles, youth-safety training, and cleanup safety briefings. National City adults mentor BIPOC youth with documented protocols — not improvisation.
What does Ocean Stewards mentorship involve?+
Weekly Tuesday–Thursday after-school support for BIPOC teens ages 13–17 — tutoring, environmental literacy assistance, and Thursday beach day support. National City adults commit to consistent mentorship across the school year.
Are volunteer programs in National City really free?+
Yes. All Un Mar de Colores programs in National City are 100% free — including 3/2mm wetsuits, soft-top surfboards, transportation from partner schools like Central Elementary (National City), Kimball Elementary, Olivewood Elementary, and certified bilingual instruction. Funding comes from the San Diego Foundation, community grants, and individual donors. No National City family has ever paid for our programming.
Where exactly do volunteer programs happen in National City?+
National City is 8 miles inland from the coast, so our cohorts are shuttled to Imperial Beach (8 miles) — our nearest Un Mar teaching beach. Classroom components including curriculum, cultural arts, and tutoring happen at National School District and partner schools inside National City.
What ages can enroll in National City?+
We serve youth ages 18+. In National City specifically, our recruitment runs through National School District / Sweetwater Union High — with priority enrollment for students from Central Elementary (National City), Kimball Elementary, Olivewood Elementary and 1 other Title I schools. Cohorts are age-appropriate (One Ocean for 6–12, Ocean Stewards for 13–17).
Does my child need to know how to swim before starting?+
No. We begin every cohort with ocean-safety fundamentals in chest-deep whitewater at Imperial Beach (8 miles), supervised by instructors certified by the San Diego Fire-Rescue Lifeguard Division. Water comfort is built progressively. In National City, we also run pre-cohort pool-familiarization sessions at inland pools via our National School District partnership for students who request extra comfort-building.
Are lessons taught in Spanish in National City?+
Yes. All Un Mar de Colores programs are bilingual — and in National City, where 61% of households are Spanish-speaking, we intentionally pair at least one bilingual coach to every session. Cultural programming is delivered in both languages, and parent communications are always sent in Spanish and English.
How is Un Mar de Colores different from other volunteer programs in National City?+
Three ways: (1) everything is free, while most National City surf programs charge $50–$150 per lesson; (2) we are BIPOC-led and our coaches reflect the 91%-BIPOC National City community we serve; (3) our curriculum includes environmental justice, Kumeyaay coastal history, and cultural arts — not just surf skills. We exist because the ocean should belong to everyone in National City, not just those who can afford access.
How do I sign my National City child up?+
Visit our sign-up page or contact us directly. Priority enrollment goes to students of Central Elementary (National City), Kimball Elementary, Olivewood Elementary and referrals from National School District and National City Public Library. Summer cohorts fill 3–4 weeks before start, so early contact is recommended.
