Retaining Wall Installation
Clackamas properties with sloped yards and hillside lots are exactly where retaining wall installation makes the biggest difference. The combination of clay soils, heavy winter rainfall, and natural grade changes across much of the Clackamas area means poorly supported slopes can erode and shift over time. Monaghan’s designs and builds retaining walls sized for the specific conditions on your property. Whether you need a single low wall to level a planting bed or a multi-tiered system to reclaim a steeply sloped backyard. Every installation comes with a workmanship warranty and a free written estimate before any work begins.
New Sod Lawn Installation
The moderate temperatures and consistent rainfall in Clackamas, Oregon create ideal conditions for sod establishment, particularly in late spring and early fall when ground temperatures support fast root development. Monaghan’s Landscaping has been installing sod lawns across the Clackamas area for nearly four decades, sourcing varieties matched to local growing conditions, including the perennial ryegrass and fine fescue blends recommended by OSU Extension for western Oregon lawns. Proper ground preparation is what separates a sod installation that thrives from one that struggles, and we handle every step from grading to finished lawn.
Sprinkler System Installation
Keeping a lawn healthy through Clackamas summers without an automatic sprinkler system means moving hoses, guessing at coverage, and watching dry patches develop in July and August when rainfall drops off. Monaghan’s designs irrigation systems zone by zone, accounting for the specific layout, soil type, and sun exposure on your property, because one schedule for everything wastes water and leaves some areas too wet while others stay dry. We serve residential properties throughout Clackamas, including the larger lots in Clackamas East and Clackamas Northeast where hand watering becomes especially impractical.
Artificial Turf Installation
Clackamas gets significant rainfall from October through May, and properties with heavy tree canopy or poor drainage often end up with muddy, worn patches that never fully recover no matter how much reseeding gets thrown at them. Artificial turf solves the problem permanently. Modern synthetic grass installed by Monaghan’s Landscaping looks and feels like the real thing, holds up under pets and kids, and stays green and clean through every Clackamas winter without mowing, watering, or reseeding. For shaded backyards where natural grass refuses to grow, it’s one of the most practical long-term investments available.
Paver Installation
A paver patio, driveway, or walkway is only as good as what’s underneath it, and in Clackamas the clay soils that shift with seasonal moisture changes make base preparation especially important. Monaghan’s Landscaping has been installing pavers across the Clackamas area for more than 38 years, and we know the difference between a base that holds and one that lets pavers settle and separate within a few seasons. We work with a wide range of styles and materials to match your home, from classic tumbled stone to clean modern concrete pavers.
Drainage Solutions
Clackamas properties in neighborhoods like Sunnyside, Mount Scott, and the areas around Fuller Road often sit on flat to gently sloping ground where water has no natural exit path during the wet season. We install French drains, catch basins, and downspout routing systems that give water a clear route off the property instead of letting it pool in the yard.
Beyond our five core services, we handle a full range of residential and commercial landscaping projects across the Portland metro area.
Every project, from a simple mulch installation to a full outdoor kitchen build, gets the same treatment: a written proposal with line-item pricing and a defined scope before work starts.

Q: What areas of Clackamas do you serve?
We serve all of Clackamas, Oregon and the surrounding communities throughout Clackamas County. Our crews regularly work in Clackamas East, Clackamas Northeast, Clackamas Southwest, Clackamas West, and the Town Center area. If you’re not sure whether your address falls within our service area, give us a call. As a Clackamas, Oregon landscaper serving the full metro region, we can usually accommodate properties that fall just outside these boundaries as well.
Q: Do you work on steep or hilly Clackamas properties?
Yes. Hillside and sloped properties are some of our most common work in the Clackamas area. The terrain along the foothills and near the Clackamas River corridor frequently involves significant grade changes that require retaining walls, terracing, re-grading, or drainage solutions before other landscaping work can begin. Our crews have the equipment and experience to work safely and effectively on challenging slopes, and we’ve completed hundreds of hillside projects throughout Clackamas County over the years.
Q: What type of sod grows best in Clackamas’s climate?
OSU Extension recommends perennial ryegrass and fine fescue blends for western Oregon lawns, and those varieties perform well in Clackamas given the region’s mild, wet winters and moderately dry summers. Perennial ryegrass establishes quickly and holds up under foot traffic, while fine fescue tolerates shade and lower-fertility soils, making blends of the two well suited to the range of conditions found across Clackamas properties. We source locally appropriate varieties and match the sod to the specific conditions on your property.
Q: Do you work on properties near the Clackamas River corridor?
Yes. Monaghan’s regularly works on properties throughout the Clackamas River corridor, including lots near the water where soil saturation, erosion, and flood-plain considerations affect the scope of landscaping work. Retaining walls on these properties require careful engineering to handle the seasonal moisture load, and grading work needs to account for drainage toward or away from the waterway. We assess river-adjacent sites carefully during the free estimate and confirm any county permit or setback requirements that apply before any work begins.
Q: What permits are required for retaining walls in Clackamas?
Permit requirements for retaining walls in Clackamas are administered by Clackamas County. Generally, walls over four feet in height (measured from the bottom of the footing) require a building permit, and walls on or near property lines may have additional setback requirements. Monaghan’s Landscaping is familiar with local permitting standards and can advise you on what’s required for your specific project during the estimate process.
Q: Do permit requirements differ for unincorporated Clackamas properties?
Yes, and it’s an important distinction. Clackamas is an unincorporated community, meaning permits are issued through Clackamas County Development Services rather than a city permit office. For retaining walls above four feet, grading work, or projects near waterways, the county review process applies. Monaghan’s is familiar with county permitting requirements throughout the Clackamas area and handles the permit process as part of every applicable project, including pulling permits and coordinating required inspections. We confirm what’s required for your specific lot during the free estimate before any work begins.
Q: Do you work on larger lot and semi-rural properties in Clackamas?
Yes. Clackamas has a wider range of lot sizes than most of the surrounding cities, from standard suburban parcels near Clackamas Town Center to larger semi-rural properties further from the urban core. Bigger lots bring different challenges: longer sprinkler system runs, larger retaining wall projects, more extensive grading requirements, and sod installations that require careful soil prep across more square footage. Monaghan’s crews are experienced across that full range and size the scope of every estimate to the actual property rather than applying a one-size approach.
Q: How do I get a free estimate for my Clackamas landscaping project?
The easiest ways to reach us are by phone at (503) 847-9110 or by filling out the quick quote form on this page. We’ll follow up promptly to schedule a free on-site visit and put together a written estimate. There’s no cost and no obligation, just a straightforward conversation about your project and what it would take to get it done right.

Your Neighbors Will Notice the Difference
We're committed to using clean, renewable energy. All-electric mowers, trimmers, and blowers running at 65-70 dB, roughly the volume of a normal conversation. Most landscaping crews show up with gas equipment at 85+ decibels with exhaust fumes drifting into open windows. We don't think that's acceptable anymore. No fumes. No noise complaints. Just the work getting done.
"The crew showed up on time and cleaned the site at the end of each day, and they were all incredibly talented and friendly. The final outcome exceeds expectations. The project was to remove marshy grass, put in drainage, then install architectural slabs with Mexican pebbles, topped off with low voltage lighting which is amazing."
