|---|---|
| No fixed day-of-week schedule under ACWD baseline | Year-round water-waste rules apply; emergency ordinance may activate |
Allowed Watering Hours
ACWD rescinded its Water Shortage Emergency Ordinance in 2023 after wet winters refilled regional supplies, but California's permanent year-round water-waste rules remain in force: no irrigation within 48 hours of measurable rainfall, no irrigation runoff onto sidewalks or streets, no spraying hardscape with potable water, hoses must have shut-off nozzles, decorative fountains must recirculate. ACWD can re-activate the Water Shortage Emergency Ordinance at any board meeting if regional conditions deteriorate – verify current status at acwd.org/WSEOrdinance before assuming this page is up to date.
Still Allowed
💧 Hand Watering
Allowed with shut-off nozzle. Hours: Any day with a shut-off nozzle.
🌿 Drip Irrigation
Exempt from day-of-week limits. Must follow allowed hours.
Fines & Enforcement
Drought surcharges suspended; permanent water-waste rules carry up to $100 per occurrence
ACWD does not currently impose drought surcharges (these were rescinded in 2023). California's permanent water-waste rules remain enforceable through ACWD code enforcement and the City of Fremont Code Enforcement office for visible violations; first detected violation typically draws a written warning, repeat violations up to $100 per occurrence. If ACWD reactivates the Water Shortage Emergency Ordinance, drought surcharges and per-violation fines will reapply per the ordinance schedule.

California Water Code §10631.5 and Civil Code §4735 prohibit HOA fines for drought-compliant brown lawns during a declared shortage and protect homeowners who reduce irrigation. These protections fully apply if ACWD declares a Water Shortage Emergency. Under ACWD's current baseline (no formal emergency), the protections still cover any landscape change made for water conservation, but document the state-level conservation framework if your HOA challenges a brown lawn.
If your homeowners association sends a violation notice for a dormant or brown lawn during the current restriction period, respond in writing citing the applicable law and include a copy of the current restriction order from Alameda County Water District. Most HOAs will rescind the notice once they are made aware of the legal protections in place. If the issue persists, contact your county’s code enforcement division for assistance.
Why These Restrictions Exist
Fremont is served by the Alameda County Water District (ACWD), a California special district that supplies water to roughly 350,000 residents across Fremont, Newark, and Union City – the so-called Tri-City area of southern Alameda County. ACWD is NOT a Metropolitan Water District (MWD) member and is NOT part of EBMUD; it operates a fully independent framework with three distinct source supplies.
ACWD's source water mix
- Niles Cone Groundwater Basin (local aquifer in the Niles district)
- Hetch Hetchy Aqueduct purchase from the San Francisco Public Utilities Commission (SFPUC)
- State Water Project deliveries through the South Bay Aqueduct
This three-source diversification makes ACWD more drought-resilient than single-source utilities, and it is why the framework is independent of both MWD's Colorado River + SWP-only system and EBMUD's Mokelumne-only system.
ACWD declared a Water Shortage Emergency in 2021–2022 with a 15% reduction goal across the Tri-City area, then rescinded the ordinance in 2023 after wet winters restored Bay Area supplies. ACWD remains at baseline (no formal emergency) as of the most recent reporting; verify at acwd.org before making major irrigation decisions.
Fremont is home to the Tesla Fremont Factory (the company's California assembly plant) – a major industrial water user with its own commercial water account. Fremont includes the historical Niles, Centerville, Mission San Jose, Warm Springs, and Irvington districts, each with distinctive landscape character but all on the same ACWD framework.
This deficit has accumulated over the current water year and represents a significant departure from historical averages for the Fremont area. Water supply reservoirs and aquifer levels are well below seasonal targets, necessitating mandatory conservation measures.
How to Keep Your Lawn Alive During Fremont Water Restrictions
11 tips tailored for Fremont homeowners during ACWD Baseline Conservation – verify current stage at acwd.org restrictions.
ACWD is currently at baseline (no formal Water Shortage Emergency) – but California's permanent year-round water-waste rules still apply: no runoff, no hardscape hosing, no irrigation within 48 hours of rain.
Verify ACWD's current stage at acwd.org/WSEOrdinance before assuming this page is up to date – the Water Shortage Emergency Ordinance can be reactivated at any board meeting.
Bay Area cool-summer climate makes Tall Fescue + drought-tolerant California-Friendly groundcovers a strong combination – much less stressed than Central Valley fescue.
Inland Fremont neighbourhoods (Mission San Jose, Warm Springs) are slightly hotter than coastal-influenced Niles and Centerville – adjust irrigation accordingly.
ACWD's regional turf-replacement rebate ($1.50–$3/sq ft, up to 1,000 sq ft per parcel) is the primary program – apply at acwd.org 'Conservation' before removing turf.
Niles Cone Groundwater Basin is a major regional aquifer; ACWD's recharge facilities along Alameda Creek keep basin levels stable through dry years.
Install a smart controller (Hunter, Rain Bird, Rachio) with a rain sensor – ACWD rebates cover up to $80 on WaterSense-labeled controllers.
Mulch all ornamental beds 3 inches deep with arborist wood chips – Bay Area clay-loam benefits from mulch and chips are typically free from local tree services.
Drip-irrigate all trees, shrubs, and vegetable beds – drip is exempt from any future stage-based day-of-week limits and uses 30–50% less water than overhead spray.
Replace any narrow grass strips between sidewalk and street with low-water California-Friendly groundcovers – these strips are the lowest-use, highest-visibility turf removal opportunities.
Track monthly water use at acwd.org 'My Account' – if ACWD reactivates the Water Shortage Emergency Ordinance, the framework typically asks for a 15% reduction across the Tri-City service area.
