Announcements

As summer gives way to fall, our landscape teams are preparing Ladera Ranch common areas for the cooler months ahead. From seasonal turf maintenance and irrigation adjustments to landscape enhancements and ongoing maintenance initiatives, there is plenty happening throughout the community. In this quarterly edition of Ladera Landscape, we're pleased to share updates on the work underway to support the beauty, health, and sustainability of Ladera Ranch's landscapes.

Pest Management Update

Ladera Ranch Maintenance Corporation (LARMAC) continues to evaluate alternative approaches to landscape and pest management as part of its ongoing commitment to reducing reliance on synthetic pesticides and promoting more sustainable landscape maintenance practices.

The current pause on the use of Lifeline, Atrimmec, and Specticle G remains in place, while pilot programs are underway to evaluate alternative approaches to weed management and insect control.

As part of the insect control pilot, two Village Club facilities are participating through the end of the year:

• Flintridge Clubhouse: No insecticide treatments will be applied during the pilot period.
• Avendale Clubhouse: An organic-based insect control treatment will be evaluated during the same period.

These pilot programs will help LARMAC assess the effectiveness, maintenance requirements, and long-term feasibility of alternative treatment methods under real-world community conditions. Findings will help inform future landscape management practices and the development of LARMAC's updated Organic Land Management Plan.

Residents are encouraged to visit the Integrated Pest Management page for updates on pilot programs, treatment notices, Landscape Advisory Committee meetings, and additional information about ongoing landscape and pest management efforts.

A Busy Summer for Irrigation

Summer's warmer temperatures and increased landscape water demands place additional strain on Ladera Ranch's extensive irrigation system. As temperatures rise, more water is lost through evaporation and plant transpiration, requiring longer irrigation runtimes to maintain healthy landscapes. These increased demands can expose weaknesses in aging pipes, valves, and other components, resulting in more frequent irrigation breaks and repairs.

Throughout the summer, irrigation crews spend considerable time responding to mainline breaks and other system repairs, many of which can be labor-intensive and require significant time and resources to complete.

As temperatures cool and irrigation demands decrease in the fall, crews can shift more of their attention toward preventative maintenance and system inspections. This includes patrolling the community's extensive trail network to identify irrigation leaks, overspray, and drainage concerns that could contribute to trail deterioration or unsafe conditions, particularly ahead of the rainy season. Crews will also continue evaluating areas with recurring irrigation issues and identifying opportunities for long-term system improvements.

This seasonal shift allows LARMAC to move from the repair-intensive demands of summer toward more proactive system maintenance, helping protect community infrastructure, conserve water, and prepare our landscapes for the cooler months ahead.

Turf Maintenance, Why the Grass May Look Different

Kikuyu grass is widely used throughout Ladera Ranch because of its many benefits, including durability, drought tolerance, and its ability to recover from heavy use. However, like all turfgrass varieties, Kikuyu has its challenges. This summer's unusually warm and humid conditions likely contributed to increased fungal activity, which can damage turf roots and cause thinning or brown patches. To help affected areas recover, landscape crews are implementing maintenance practices such as aeration, dethatching, and targeted fertilization to encourage healthy growth.

Residents may also notice changes in turf appearance as temperatures cool. Kikuyu is a warm-season grass that naturally enters dormancy during the winter months, often turning brown until warmer temperatures return in the spring. While overseeding with cool-season grass can provide temporary winter color, it does not necessarily improve the long-term health of the underlying Kikuyu turf and requires additional water and maintenance to establish.

After careful evaluation, LARMAC has discontinued much of its traditional fall overseeding program this year. This shift allows the Association to focus resources on more sustainable, long-term turf management practices, including targeted turf replacement where needed, while conserving water, reducing maintenance demands, and supporting healthier community landscapes.

Drainage and Urban Runoff Management

Did you know that Ladera Ranch was designed with an innovative stormwater and urban runoff management system?

As part of the community's original development, the developer created Sienna Botanica and Horno Basin to collect and manage stormwater and everyday urban runoff from much of Ladera Ranch.

While many residents regularly walk along Sienna Botanica, fewer may be familiar with Horno Basin, located in the southern portion of Ladera Ranch between Terramor and Covenant Hills. Together, these interconnected facilities use natural vegetation, ponds, and spillways to help slow water flows, capture sediment, and improve water quality before runoff enters Horno Creek. The system also provides valuable habitat for birds and other wildlife.

Maintaining this infrastructure is an important part of LARMAC's landscape management responsibilities. LARMAC contracts with Boulder Earthwork Inc. to perform specialized maintenance, including maintenance of the forebay and aftbay, vegetation clearing to maintain proper water flow, and necessary spillway repairs.

These ongoing efforts help preserve the system's effectiveness, protect downstream waterways, and support the environmental health of our community.

Trail Maintenance and Winter Preparation

Residents and visitors enjoy Ladera Ranch's approximately 17 miles of trails throughout the year. To keep these trails safe and in good condition, LARMAC continues to invest in restoration and preventative maintenance. Recent improvements include refreshing trail surfaces with decomposed granite (DG) and replacing older plastic water bars with more user-friendly trail humps designed to redirect runoff into nearby drainage areas.

As we approach the rainy season, additional erosion-control measures are planned for select locations, including the placement of specialized sandbags along downhill trail sections near street crossings. These bags will be filled with decomposed granite, allowing the material to be reused for trail maintenance once the rainy season has passed.

LARMAC's contractors, Boulder Earthwork and City Green, are performing this specialized work. While residents may notice temporary disruptions in certain areas, these improvements are intended to reduce erosion, improve trail conditions, and protect the community's investment in its extensive trail network.

Giving Our Sports Fields a Winter Break

LARMAC schedules two major sports field maintenance periods each year, one in summer and one in winter, to maintain safe, healthy, and playable turf conditions. To provide consistency for residents and sports organizations, the winter maintenance period begins each year on the Monday following Thanksgiving.

The primary focus of winter maintenance is improving turf and soil health while preparing fields for the winter and spring sports seasons. Unlike many other turf areas throughout the community, sports fields continue to be overseeded with cool-season grass to provide a durable, green playing surface during the colder months. This is particularly important because the existing warm-season turf naturally goes dormant as temperatures cool, leaving fields more susceptible to thinning, muddy conditions, and wear from athletic activities.

During the closure period, landscape crews perform a variety of maintenance activities, including:

• Dethatching and aerating turf
• Grading low spots and repairing uneven surfaces
• Replacing worn or damaged turf with new sod
• Inspecting and adjusting irrigation systems
• Leaching accumulated salts from the soil
• Applying soil amendments and fertilizer
• Overseeding and applying topdressing material

These activities require extended periods of limited use to allow new grass to establish and field conditions to improve before reopening.

Scheduled Field Reopenings

• School-adjacent sports fields: Monday, January 4*
• Wagsdale Park (Lower Field) and Cox Sports Park: Monday, February 1*

*Reopening dates are weather-dependent and subject to field conditions.

Community Projects and Improvements

Throughout the year, LARMAC undertakes a wide variety of landscape improvement projects, ranging from landscape renovations and park enhancements to tree management and fire mitigation efforts. These projects help maintain the appearance, safety, and long-term sustainability of our community's common areas.

Recent and Ongoing Projects

• Wagsdale Dog Park Seasonal Maintenance: Fall maintenance includes replacing worn turf, grading low spots, aerating and fertilizing turf, compacting trail surfaces, and cleaning benches and light poles. These improvements help maintain a safe and enjoyable environment for residents and their pets. The dog park is scheduled to reopen on Friday, October 16, at 3:00 p.m., weather permitting.
• OCFA Tree Maintenance and Fire Safety: Selective tree trimming and removals were completed on designated slopes within Slope 2 to address vegetation management requirements identified by the Orange County Fire Authority (OCFA) during its May inspection. This work supports fire prevention efforts and compliance with applicable fire safety requirements.
• Catalina Vista Fire Mitigation Project: Restoration work, including post-fire cleanup, erosion control measures, and irrigation repairs, has been completed. The final phase, hydroseeding to help reestablish vegetation and stabilize affected slopes, is scheduled for the week of October 19.
• Narrow Fire Cleanup and Mitigation Project: Post-fire cleanup, erosion control measures, and irrigation repairs have been completed. Hydroseeding is scheduled for the week of October 19 as the final phase of the restoration effort.

Upcoming Projects
