Naviagtion Background


The Mariners’ Green Association No. Three HOA was established to market and manage the property. The HOA is administrated by Tri-State Enterprises, Inc, one of the premier property management organizations in the Bay Area. Amongst other services, the HOA through Tri-State provides: weekly site inspections, complete record keeping, and 24/7 person-to-person accessibility and support to handle emergencies, maintenance, and complaints. The HOA enhances property values and tenant satisfaction, while lowering property maintenance costs.

The Mariners’ Green Association No. Three neighborhood is located within a horseshoe bend in Seal Slough, just south of Seal Point and the San Francisco Bay, in San Mateo, California, 94404. Historic downtown San Mateo is just to the west and Foster City to the east. It’s convenient to Bay Area Highways 101 and 92. Even more convenient is access to the water — many homes in the association have their own boat dock and members share a well-maintained community dock.

Mariner's Green Courtyard and Gardens

Besides the community dock, association members share use of a pool with BBQ areas, spa, sauna, a tennis court, bocce ball courts, and beautifully landscaped gardens and walkways. A clubhouse with meeting/party room and kitchen is pool-side and available to members to rent for events. There are additional assigned parking spaces for boat trailers and other vehicles within the neighborhood.

Just across Seal Slough, Parkside Aquatic Park is a short paddle away and, within our neighborhood, Mariners’ Green Park has large lawns, playgrounds, picnic areas, and a baseball diamond. You’ll be steps away from the Greenbelt with great walking and biking trails and only a few blocks from Bridge Point Shopping Center.

Elementary and middle school students will attend the San Mateo-Foster City School District, while high school students will attend San Mateo Union High School District — some of the top-rated schools along the Peninsula.
