ZIP 95002 — Alviso

Alviso is a low-lying area with significant historical flood risk due to its proximity to the San Francisco Bay and the Guadalupe River, necessitating ongoing levee maintenance and flood protection infrastructure.

The area is characterized by its proximity to the Silicon Valley tech corridor, though development is constrained by environmental and flood-plain regulations.

Composed from the ARED governance burden registry — tier-native tax structure (state + county + city + special districts), never averaged. State (California) — Mello-Roos Community Facilities Act Special Parcel Tax Assessment: Levies an annual direct, non-ad valorem special tax directly on the parcel's secured property tax bill to fund designated community infrastructure (e.g., roads, sewer facilities, school facilities, emergency services) and repay municipal debt bonds. State (California) — California Homeowners' Property Tax Exemption: Reduces the taxable assessed value of the qualifying owner-occupied principal residence by $7,000 against the county assessment roll, generating a direct tax savings of approximately $70 annually (computed as $7,000 × 1% base rate). State (California) — California Proposition 13 Ad Valorem Real Property Tax: Establishes a base ad valorem tax rate capped at 1.0% of assessed value plus voter-approved local indebtedness and direct assessments (typically resulting in an effective tax rate of 1.1% to 1.25%).

Residents have direct access to major transit corridors including Highway 237 and I-880, providing a commute profile oriented toward the San Jose and Santa Clara employment hubs.

The area features the Alviso Marina County Park and access to the Don Edwards San Francisco Bay National Wildlife Refuge, offering extensive trails and waterfront recreation.

The rental market is limited by the small housing stock, with a mix of older single-family homes and some multi-family units; vacancy pressure remains high due to the constrained supply.

The economy is heavily influenced by the broader San Jose-Sunnyvale-Santa Clara metro area, with a strong concentration in technology, finance, and professional services.

The area is served by local road networks connecting to the VTA light rail system and major regional highways, facilitating access to the wider South Bay.

Development is strictly managed due to the area's location within a flood-prone basin and protected wildlife habitat zones.

The Santa Clara County Assessor manages property valuations, applying Proposition 13 limits to annual assessment increases.

Parcels are subject to Santa Clara County special districts, including flood control and water management districts.

Property insurance premiums are elevated due to the high flood-risk designation of the Alviso basin.
