A technical spec guide for Denver landscape designers navigating water restrictions and HOA guidelines. Key recommendations include:

• UV-Stabilized Fiber: At 5,280 feet, UV exposure is 25% higher than at sea level. Specs require minimum 8,000 Denier UV-stabilized polyethylene monofilament with HALS additives and a 10- to 15-year fade warranty to prevent silvering.
• Sub-base for Front Range Clay: A 4-inch minimum excavation, geotextile fabric, 3-4 inches of compacted Class 6 road base, and a 1/4-inch decomposed granite cap to resist clay swell and frost heave.
• Infill Options: Kiln-dried silica sand for low-traffic; acrylic-coated antimicrobial sand or zeolite blends (like Envirofill) for pet-friendly-turf; avoid crumb rubber due to 150°F+ surface temperatures.
• HOA Approval Packet: Includes manufacturer specs, physical samples, site plans, sub-base cross-sections, and neighborhood project photos to prevent project delays.
