Emerald Lake Hills (Emerald Hills) Homes and Neighborhood Guide
Redwood City neighborhood guideUnincorporated San Mateo County
Emerald Lake Hills is unincorporated San Mateo County with a Redwood City mailing address and the 94062 ZIP code, so local services come from the county rather than the city. It sits in oak covered hills between Woodside, Redwood City and San Carlos, roughly bounded by Edgewood Road, Alameda de las Pulgas, Farm Hill Boulevard and Interstate 280. The name Emerald Hills first appeared in a 1920 sales brochure.
In the 1920s developers Leonard and Holt marketed the hills to San Franciscans as a weekend retreat with a largely fog free climate, busing visitors in for picnics at the lakes. Lower Emerald Lake is run by the Emerald Lake Country Club and Upper Emerald Lake is owned by bordering households, so both are private. Edgewood County Park and Natural Preserve, 467 acres of grassland, chaparral and woods, borders the hills with trails for hikers and riders.
Emerald Lake Hills is shaded. Borders are approximate, see the Redwood City map for the full picture.

Homes and Streets
Homes went up over many decades, starting with 1920s lots and continuing after a sewer system replaced septic tanks in 1982 and a building moratorium ended in 1986. The result is a varied mix of home eras and styles on irregular, often steep, oak studded lots. About 30 miles of roads were laid out by 1927, and residents have worked to keep them narrow and winding.
