Do I need permits for outdoor projects in Devon and Easttown Township?

Yes. Devon falls entirely within Easttown Township, which requires building permits for swimming pools, retaining walls above a certain height, and significant grading work. For any land disturbance at or exceeding one acre, PA DEP Chapter 102 erosion and sedimentation control requirements apply, and the Chester County Conservation District is the reviewing agency for erosion plans in this area. Blue Tree coordinates permit applications on your behalf as part of its standard project workflow, drawing on established working relationships with Easttown Township and Chester County agencies built over decades of work in this corridor.

How long has Blue Tree served Devon and Easttown Township?

Blue Tree Outdoor Living has been operating in Southeastern PA for 43 years, founded in Norristown in 1983 and based out of the Schwenksville design center since 2008. Devon and the Easttown Township corridor have been part of the service area since the earliest years. The crew averages 13 to 14 year employee tenure, so the people who know your neighborhood have been working it for a long time. Blue Tree has 15 years of pool construction experience in the region and backs every pool shell with a lifetime structural warranty.

What areas does Blue Tree serve for outdoor living in Devon?

Blue Tree works from its Skippack headquarters and builds throughout Devon and the Chester County Main Line, including nearby communities such as Berwyn, Strafford, Wayne, Paoli, and Malvern. Beyond Chester County, Blue Tree serves homeowners across all seven counties: Montgomery, Bucks, Chester, Delaware, Lehigh, Berks, and Philadelphia Counties.

Q: What landscape and hardscape challenges are most common on Devon properties?

Devon sits at a transition point where the well-drained Cecil sandy loam soils typical of Chester County uplands meet heavier clay profiles toward Montgomery County, so drainage planning is critical before any patio or pool installation. The Devon Horse Show grounds area and Upper Gulph Road corridor have some of the highest deer pressure in Southeastern PA, which shapes plant selection for every landscape design. Spotted Lanternfly is quarantined throughout Chester County, and Japanese beetle grub damage to turf peaks June through August. Easttown Township building permits are required for pools, patios, and structures.

Why Devon Homeowners Have Trusted Blue Tree Since 1983

Our story started in 1983, and from our Skippack headquarters we have designed and built across the Main Line and Chester County for more than four decades. What began as a small residential landscape operation has grown into a full-service design-build firm with 70 to 90 team members, six degree-holding designers with a combined 100-plus years of experience, and a production calendar that spans pools, patios, landscapes, turf care, and year-round maintenance.

Our headquarters is at 4494 Skippack Pike, and we have worked across the Main Line for decades. We file permits with Easttown and the surrounding townships, we know the clay and rocky Piedmont soils of the area, and we understand exactly what it takes to build well on Devon's established estate properties, where design standards run high.

What matters most to us is the relationship. We are building pools and patios for the children of clients we worked with 25 years ago. Our designers develop friendships with homeowners that last long after the project is complete. As Jeff, our founder, was told early on: "All you have in life is your reputation." That advice has guided every decision we have made for more than four decades, and it is why Devon homeowners continue to trust Blue Tree with their most important outdoor projects.

Custom Pool Construction

Blue Tree Outdoor Living is one of the only full-service design-build firms serving Devon that handles custom pool construction in-house, from design and permitting through excavation, plumbing, plaster, and decking. We have been building inground pools for 15 years using premium Jandy equipment, and our approach is different: we do not just build the pool and leave. We design the entire backyard environment, including the pool, patio, landscaping, lighting, and drainage, as one integrated project. That is what turnkey means at Blue Tree.

Landscape Design & Installation

Our landscape design and installation services are led by degree-holding designers who create custom plans using CAD software and 3D renderings. We source approximately 90 percent of our plant material from local growers, design for four-season interest and long-term performance, and back every planting with a one-year warranty. Whether you need a foundation planting refresh, a native garden installation, or a complete property transformation, our design team builds the plan around your vision, lifestyle, and budget.

Hardscape Design & Installation

From paver patios and outdoor kitchens to retaining walls, fire pits, and walkways, our hardscape design and installation services transform your property with durable, low-maintenance materials. All work complies with Easttown and surrounding township building codes.

Designed for Devon's Climate, Soil, and Character

Devon sits in Easttown Township on the Chester County Main Line, one of the most established outdoor living markets in the region. Main Line properties in Devon tend toward larger wooded lots with existing landscape structures — retaining walls, specimen trees, mature hedgerows, and established plantings — that constrain new construction but also provide the privacy and aesthetic character that homeowners want to preserve. Blue Tree designs around existing significant site features rather than proposing clean-slate plans that discard them. Easttown Township issues its own permits, with specific setback and impervious-surface provisions for pools and hardscape that vary from neighboring municipalities. Rocky Piedmont subsoil is common in Easttown, and deeper excavations for pool shells on many Devon-area properties encounter ledge rock that requires hydraulic breaking. The Darby Creek headwaters run through parts of the township with riparian buffer restrictions on grading near the creek corridor. Chester County Conservation District reviews apply to larger grading projects. Blue Tree has served Devon and Easttown Township since 1983.

Soil around Devon is a mix of clay and rocky Piedmont ground common across the Main Line. Clay holds moisture and rock complicates excavation for pools and footings, so both have to be addressed during installation, not discovered after the fact. Soil amendment is part of nearly every planting project we complete here, and proper drainage design is built into every hardscape and pool plan.

We also design around realities Devon homeowners know: deer pressure is significant on the wooded estate lots, freeze-thaw cycles heave shallow-rooted plants and shift improperly based pavers, and the Main Line townships hold strict permitting, design, and stormwater standards. After more than four decades of building across the region, we have filed those permits and met those standards on properties throughout the Main Line. That institutional knowledge is something no newcomer can replicate.

13 to 14 Years. That's the average tenure of a Blue Tree employee. In an industry where turnover is measured in months, our people stay for decades. They stay because the culture is built on respect, collaboration, and the kind of work they're proud to put their name on.

Devon's USDA zone 7a designation and predominantly well-drained Cecil sandy loam soils support a wide range of landscape plants. On estate lots with full sun, we favor American hornbeam, native oak species, and flowering dogwood as structural trees. Shrub layers work well with inkberry holly, Virginia sweetspire, and deer-resistant varieties like Oso Easy roses and spirea. For foundation plantings near historic homes, we select cultivars appropriate to the architectural period. Turf programs target the warm-season stress window of July through August when dollar spot and summer patch pressure peaks in Chester County.
