Grass Sum Highland provides commercial landscaping consulting that takes the long view. We work with business parks and corporate facilities to design outdoor environments that use less water, require less maintenance, and contribute genuinely to ecological health.
"Sustainable grounds management is not a trend. It is a shift in how facilities understand their relationship with land."
Grass Sum Highland was established to address a gap in commercial landscaping: the distance between what facilities say about sustainability and what their grounds actually do. Most corporate campuses inherit landscapes designed for visual impact alone, with irrigation systems, plant selections, and maintenance regimes that were never evaluated for long-term viability or environmental cost.
We bring a consulting mindset to every engagement. That means asking questions before making recommendations, reading the land before drawing any plans, and being honest when a proposed solution will not hold up over time. Our work is grounded in hydrology, regional ecology, and maintenance economics.
We serve business parks, corporate campuses, and multi-building commercial facilities across the US. Our deliverables are practical documents that facilities teams, property managers, and grounds contractors can actually use.
Each service is structured around clear deliverables. We do not offer vague advisory retainers. Every engagement produces documents and plans that have a defined purpose and measurable application.
A thorough evaluation of your existing grounds, drainage patterns, soil composition, irrigation infrastructure, and vegetation inventory. We document what is present, what is underperforming, and where intervention will have the most impact. The assessment report becomes the foundation for all subsequent planning work.
Detailed technical plans for reducing water use across commercial grounds without compromising appearance or ecological function. We identify over-irrigated zones, specify appropriate irrigation technology, and design planting schemes that match water availability to plant needs. Blueprints are formatted for contractor implementation.
Plant selection and placement plans that prioritize regional suitability, seasonal resilience, and reduced maintenance burden. We work with native and adapted species that perform reliably in commercial settings, reducing mowing, fertilization, and replacement cycles. Plans include species lists, spacing diagrams, and seasonal care calendars.
A structured framework for how your grounds will be managed over a multi-year horizon. We define maintenance zones, establish performance benchmarks, and create protocols that facilities teams can follow or hand to contractors. This service is particularly valuable for business parks managing multiple buildings under a single grounds budget.
Good landscape consulting is mostly listening. We spend more time on your site than at our desks, and more time asking questions than writing recommendations.
We keep the process straightforward. There are no hidden phases or open-ended retainer structures. Here is how a typical consulting engagement unfolds.
We begin with a conversation about your facility, your current grounds management situation, and what you are hoping to achieve. This call helps us understand the scope and lets us explain honestly what consulting can and cannot accomplish for your specific context.
Based on the consultation, we define a clear scope of work. This includes which services apply, what we will assess or plan, the format of deliverables, and a timeline. Everything is documented before any fieldwork begins.
Our consultants visit the property for a structured assessment. We document conditions methodically, take measurements, photograph key areas, and interview facilities staff who know the site's history. Field notes are comprehensive because details that seem minor often turn out to matter.
Field data is analyzed against regional climate data, local plant databases, and water utility context. We develop recommendations that are specific to your site, not drawn from a generic template. Blueprints and plans are drafted, reviewed internally, and refined before delivery.
Final documents are delivered with a walkthrough session. We explain the reasoning behind each recommendation, answer questions from your team, and clarify how to hand off the plans to contractors or internal maintenance staff. You leave with everything you need to move forward.
The word "sustainable" carries a lot of weight in commercial real estate and facilities management. We use it carefully. For us, sustainable grounds management means designing and maintaining outdoor environments that can function with reduced inputs over time, support regional biodiversity where feasible, and do not degrade the ecological systems they sit within.
This is distinct from simply choosing native plants or installing drip irrigation. Those are tools, not outcomes. Sustainable outcomes require understanding how your site's hydrology, soil biology, and plant communities interact and then making decisions that support those interactions rather than working against them.
Managing how water moves through and off your site. Reducing runoff, improving infiltration, and aligning irrigation with actual plant water requirements rather than calendar schedules.
Healthy soil biology reduces the need for synthetic inputs. We assess compaction, organic matter levels, and microbial conditions and recommend practices that rebuild soil function over time.
Commercial grounds can support pollinators, birds, and beneficial insects without sacrificing the clean, professional appearance that corporate settings require. We design for both.
Sustainability and efficiency align when grounds are designed well. Fewer mowing cycles, reduced fertilizer applications, and lower irrigation volumes all follow from thoughtful initial planning.
Questions we hear regularly from facilities managers, property directors, and sustainability coordinators at commercial facilities.
Our work spans multi-building business parks, corporate campuses, office complexes, light industrial facilities with significant grounds, and mixed-use commercial developments. The common thread is that these are professionally managed properties where grounds maintenance is handled by a facilities team or contracted service. We work with properties of varying sizes, though our consulting model is particularly well-suited to sites where the grounds represent a meaningful budget line and there is interest in improving how that budget is deployed.
Landscaping contractors execute physical work: planting, mowing, irrigation installation, pruning. Consulting is about the planning layer that precedes and informs that work. We do not install anything. We assess what you have, identify what should change, and produce the documentation that tells contractors what to do and why. Many clients find that bringing in consulting before signing a new maintenance contract helps them write better specifications and get better outcomes from their contractors. The two functions complement each other rather than compete.
Fieldwork for a standard commercial site assessment typically takes one to two days on-site, depending on the size and complexity of the property. Analysis and report writing generally requires one to two weeks after fieldwork is complete. For larger multi-building campuses or sites with complex irrigation systems, both phases extend accordingly. We establish a clear timeline at the scope definition stage so there are no surprises. If your facility has a specific deadline tied to a lease renewal, budget cycle, or contractor selection, we factor that into the schedule from the start.
Yes, though the specific plant selections vary significantly by region. A low-maintenance vegetation plan for a facility in the Southwest is built around drought-adapted species that would not be appropriate in the Mid-Atlantic. Our approach is always site-specific and regionally calibrated. We draw on USDA plant hardiness data, regional native plant databases, and local water utility context when developing vegetation plans. We do not apply a single national template. The core principles of low maintenance and ecological suitability are consistent; the plant palette is always tailored to where your facility is located.
Absolutely. Most of our clients have existing contractor relationships they want to maintain. Our deliverables are designed to be handed off to contractors as clear implementation guides. We can also meet with your contractor during the scope definition phase to understand their capabilities and factor those into our recommendations. In some cases, we facilitate a briefing session with the contractor at delivery to ensure the plans are understood and implementable within their operational model. We are not trying to displace your existing service providers; we are trying to give them better direction.
We typically ask for site plans or as-built drawings if available, current irrigation system documentation, any existing grounds maintenance specifications or contracts, and a basic overview of current maintenance practices and budget structure. If you do not have formal documentation, that is not unusual and not a barrier to starting. Part of what the assessment produces is a documented baseline where none existed before. Access to the property and a point of contact who can answer operational questions during fieldwork is the most important thing we need from you.
Reach out to discuss your facility's grounds. We will respond with an honest assessment of how we might be able to help and what an engagement would involve.
