Landscape Materials in Mountain View: Compost, Mulch, and Recycled Products for Commercial and Residential Projects

Mountain View’s landscape projects operate under some of the most aggressive waste diversion targets in the Bay Area. The city’s Zero Waste Policy, adopted in 2018, sets a goal to divert 90% of waste from disposal by 2030. Mountain View currently sits at 84% diversion. For landscape contractors, property managers, and municipal procurement officers, specifying recycled-content landscape products is one of the most direct ways to push that number higher while meeting state compost and mulch mandates.

GreenWaste Recovery produces OMRI Listed bulk compost and over 90 recycled-content landscape products from yard trimmings and organics collected across Silicon Valley, including Mountain View. GreenWaste processes that material at the Z-Best Composting Facility in Gilroy and the GreenWaste Zanker Resource Recovery Facility in San Jose, returning finished products for purchase and delivery throughout Santa Clara County.

CALGreen and MWELO Compost Requirements

Mountain View enforces the state Model Water Efficient Landscape Ordinance (MWELO), which applies to all new construction with a landscape area of 500 square feet or more and rehabilitated landscapes of 2,500 square feet or more. Under MWELO Section 492.5, qualifying projects must submit a soil management report with laboratory analysis covering soil texture, infiltration rate, pH, total soluble salts, sodium content, and percent organic matter. Documentation verifying that soil report recommendations were implemented is required before project approval.

CALGreen and MWELO together require compost at a minimum rate of four cubic yards per 1,000 square feet of permeable area, incorporated to a depth of six inches, plus a minimum three-inch mulch layer on all exposed soil surfaces in planting areas. Soils testing above six percent organic matter in the top six inches are exempt, but most developed sites in Mountain View fall below that threshold, particularly on commercial campuses and multifamily properties where soil has been under landscape or hardscape for decades.

For contractors working on Mountain View projects with building permits, compost and mulch are not optional line items. They are code requirements with documented compliance thresholds. GreenWaste’s OMRI Listed compost with published lab specifications and recycled organic mulch provide the products and documentation that MWELO submittals require.

SB 1383 Procurement: Supporting Mountain View’s 90% Diversion Target

California’s SB 1383 requires jurisdictions to procure recovered organic waste products annually. Landscapers working on municipal or institutional projects can act as direct service providers and procure compost and mulch on behalf of the jurisdiction, with those purchases counting toward the mandate. For a city working toward 90% diversion, maximizing SB 1383 procurement through locally-produced recycled organics closes a measurable portion of the remaining gap.

GreenWaste’s SB 1383 compliant products include compost, mulch, and soil blends that qualify as recovered organic waste. GreenWaste provides tonnage reports, compliance certificates, and product verification documentation for municipalities and institutional facilities demonstrating annual procurement compliance.

For Mountain View property managers and commercial accounts, SB 1383 also requires all businesses and multifamily properties (5 units or more) to separate organic waste from garbage. Procurement of recycled organics products for landscape maintenance counts as a documented compliance action.

C.3 Stormwater: Compost in Bioretention Design

Development projects in Mountain View that trigger C.3 stormwater requirements under the Santa Clara Valley Urban Runoff Pollution Prevention Program (SCVURPPP) must include bioretention facilities or other green infrastructure measures to treat stormwater runoff on site.

These facilities require engineered Biotreatment Soil Media (BSM) consisting of 60% to 70% sand and 30% to 40% compost by volume, designed to achieve a minimum infiltration rate of 5 inches per hour. This creates a bulk compost demand stream for development projects separate from standard landscape applications. Civil engineers and landscape architects specifying BSM for C.3 compliance need compost with documented processing standards. GreenWaste’s OMRI Listed compost, produced under monitored conditions at Z-Best with lab-tested specs on every batch, provides the documentation that BSM specification submittals require.

GreenWaste’s custom soil blends can also be specified to meet bioretention media standards for Mountain View projects.

Water Conservation Incentives

The Santa Clara Valley Water District Landscape Rebate Program currently offers $2 per square foot for turf conversion, with rebates up to $3,000 for residential properties and up to $100,000 for commercial and multifamily sites. Current funding runs through June 30, 2026, or until depleted. Compost incorporation is a standard component of qualifying landscape conversion projects.

For Mountain View’s tech campuses and commercial properties pursuing turf conversion, rebate eligibility combined with SB 1383 procurement credit creates a dual incentive for specifying recycled-content compost and mulch from GreenWaste.
