Landscaping in Highlands Ranch, Colorado

Highlands Ranch presents landscaping challenges rooted in its development history and organizational structure. Unlike other Douglas County communities, Highlands Ranch was developed as a master-planned community with specific design standards that continue to shape what's possible on each property.

Aging Landscape Infrastructure

The most widespread challenge in Highlands Ranch is aging landscapes. Neighborhoods developed in the 1980s and 1990s now have 30-40 year old trees, shrubs, and irrigation systems. Many original blue spruces are succumbing to disease and environmental stress. Shrubs have become woody and bare at the base. Irrigation systems installed decades ago use outdated technology, waste water, and fail with increasing frequency. Complete landscape renovation is often more practical than piecemeal repairs, requiring thoughtful phasing to manage cost and maintain some curb appeal during the process.

HRCA Standards and Approval Process

The Highlands Ranch Community Association reviews and approves significant landscape changes before homeowners can proceed. This process ensures neighborhood aesthetic consistency but adds time and complexity to projects. HRCA has specific requirements for tree species, lawn percentages, hardscape materials, and maintenance standards. Some modifications require architectural review committee approval with detailed plans and specifications. We've navigated this process on hundreds of properties and design landscapes that align with HRCA expectations, minimizing revision requests and approval delays.

Compacted Clay Soil

Decades of foot traffic, irrigation, and settling have severely compacted the clay soil in established Highlands Ranch neighborhoods. This compaction prevents water infiltration, damages root systems, and makes it difficult for even established plants to thrive. Core aeration helps temporarily, but comprehensive renovation projects require deep soil amendment to break up hardpan layers and restore healthy growing conditions. New plantings in compacted soil often fail within a few years without proper soil preparation.

Open Space Integration

Many Highlands Ranch properties back to trails, open space, or the Backcountry's native grasslands. Creating successful transitions between improved landscapes and natural areas requires understanding what plants work in these interface zones, how to prevent irrigation overspray onto trails, and how to maintain defensible space for fire safety. Backcountry properties in particular need designs that look intentional rather than abrupt where cultivated landscaping meets native vegetation. We design buffer zones using native and adapted plants that bridge these areas naturally.

Water Efficiency Pressure

Centennial Water and Sanitation District serves most of Highlands Ranch and actively promotes water conservation. Many original landscapes were designed when water was cheaper and conservation was less urgent. Today, homeowners face pressure to reduce water usage while maintaining attractive properties. Transitioning from water-intensive designs to efficient landscapes while preserving mature trees and key features requires careful planning. We help homeowners identify which elements to keep and which to replace, designing phased approaches that reduce water consumption while protecting existing landscape investments.

The Highlands Ranch Community Association (HRCA) maintains design guidelines that govern landscaping across the community. Understanding these standards before starting any project prevents delays, rejections, and costly revisions. Here's what you need to know about HRCA landscaping compliance.

What Requires HRCA Approval

Minor maintenance (mowing, fertilizing, seasonal plantings) doesn't require approval. However, you typically need HRCA review for: tree removal or addition, significant shrub or plant bed changes, hardscape installation or modification (patios, walkways, retaining walls), irrigation system changes visible from the street, fence installation or replacement, and landscape lighting. When in doubt, contact HRCA before starting work.

Common HRCA Requirements

Tree species: HRCA maintains approved tree lists. Species prone to disease or unsuited for Colorado may be restricted. Replacement trees are typically required when removing existing trees.

Lawn coverage: Most areas require minimum lawn percentages, though xeriscaping options have expanded. Pure rock or hardscape front yards are generally not permitted.

Materials: Hardscape materials must complement neighborhood character. Natural stone and quality pavers are typically approved; poured concrete and certain modern materials may face restrictions in some areas.

Maintenance standards: HRCA requires landscapes be maintained in good condition. Dead plants, overgrown areas, and visible irrigation issues can result in violation notices.

The Approval Process

Submit plans to HRCA showing proposed changes, materials, and plant species. Simple projects may be approved within 2-3 weeks. Complex projects requiring architectural committee review take 4-6 weeks. We submit HRCA-compliant plans from the start, reducing revision rounds and speeding approval. Our familiarity with HRCA standards means designs that get approved without surprises.
