Foster City homeowners are converting traditional lawns to drought-tolerant landscapes faster than anywhere else on the Peninsula. The combination of rising BAWSCA water costs, California water restrictions, and genuine environmental concern has made lawn conversion the #1 landscaping project in 94404.
This guide walks through exactly how we do it — from pulling out the old lawn to the final mulch layer.
Why Foster City Homeowners Are Converting Now
Three forces are driving lawn conversion in Foster City right now:
Water costs: BAWSCA's tiered pricing structure means the more you use, the more per unit you pay. A traditional 1,500 sq ft lawn uses 40,000–80,000 gallons per year outdoors — putting most Foster City homes in the highest pricing tiers during summer months.
Water restrictions: During drought conditions (which California now treats as the baseline), BAWSCA enforces outdoor watering restrictions. Homes with traditional lawns face fines; homes with drought-tolerant landscapes are largely exempt.
Rebates: The BAWSCA turf replacement program currently offers $1–$3 per square foot — making a 1,000 sq ft conversion net $1,000–$3,000 back to the homeowner.
The 5-Step Conversion Process
Remove Existing Lawn
We use a sod cutter to remove grass and root mat in one pass. Solarization (plastic sheeting in summer) is a slower no-dig alternative for homeowners who want to DIY this step. Removed sod goes to composting facilities — nothing to landfill.
Amend the Soil
Foster City's bay mud clay is the most important thing to address before planting. We till in compost (4–6 inches) and gypium to break up clay structure, improve drainage, and create the aerated soil environment that native plant root systems need. Skipping this step is the #1 reason DIY conversions fail.
Install Drip Irrigation
Drip irrigation is required for BAWSCA rebate eligibility and is the most water-efficient way to establish new plantings. We design zone-by-zone based on plant water needs — succulents on one zone, shrubs on another. Smart controllers with weather adjustment cut water use further.
Plant California Natives and Drought-Tolerant Species
We select plants based on sun exposure, soil depth, HOA requirements, and aesthetic goals. Fall planting (September–November) gives plants the best establishment window — cool temperatures and early rains reduce supplemental irrigation needs during the critical first year.
Apply Deep Mulch Layer
Three inches of wood chip mulch is the finishing step — and one of the most important. Mulch suppresses weeds, retains soil moisture, moderates soil temperature, and feeds soil biology as it breaks down. We use arborist chips where available, which are superior to dyed decorative mulch.
💧 BAWSCA Rebate — How to Qualify
To qualify for the Foster City / BAWSCA turf replacement rebate: (1) Take "before" photos of the existing lawn, (2) Apply for the rebate before starting work, (3) Remove at least 500 sq ft of irrigated turf, (4) Replace with drought-tolerant plants or permeable hardscape, (5) Install drip or bubbler irrigation, (6) Request a post-installation inspection. Rebate: $1–$3/sq ft. We handle the paperwork for customers on full-service projects.
Water Savings — Real Numbers for Foster City
A traditional bluegrass lawn in Foster City uses approximately 44 gallons per square foot per year (UC Davis calculation for coastal California). A drought-tolerant landscape uses 10–18 gallons per square foot per year once established.
For a 1,500 sq ft front yard: traditional lawn uses ~66,000 gallons/year. Drought-tolerant landscape uses ~15,000–27,000 gallons/year. That's 39,000–51,000 gallons saved — roughly $1,000–$1,800 in annual water cost reduction at current BAWSCA rates.
HOA Considerations in Foster City
Many Foster City neighborhoods have HOAs with landscaping requirements. Communities like Shell Cove, Marlin Cove, Edgewater Isle, and Beach Park Apartments have specific rules about what front yards can look like.
We've worked with HOAs across Foster City and know which ones require design pre-approval, which prohibit certain plant types, and which have updated their rules to encourage drought-tolerant landscapes. We handle HOA submission packages as part of our full-service projects.
