Grading & Drainage: Groundwork That Shapes It All
Structure Starts Below the Surface
Every great outdoor space begins with a stable foundation. And that means grading and drainage done right, before the stone is set or the plants go in. At Brandywine, we assess water flow, soil conditions, and grade relationships with the same care we give to stonework or planting design. Because when the base is solid, everything above it holds up.
Not Just a Prep Step, A Strategic Layer
Grading and drainage aren’t just box-checking exercises. They’re strategic design elements that shape how a space functions and lasts. From subtle swales to full regrades and underground infrastructure, we tailor solutions that support long-term performance and visual cohesion. No soggy lawns. No cracked patios. Just smart groundwork that protects your investment.
-
Adjusting grades to manage runoff, shape views, and prepare build areas.
-
Directing water flow with contour adjustments and shallow channels that move water naturally.
-
Connecting roof runoff to subsurface systems to avoid pooling near the foundation.
-
Subsurface water redirection systems installed with proper slope, gravel, and geotextile.
-
Township-approved grading plans and BMP (best management practice) solutions for larger builds.
-
Ensuring the site is clean, compacted, and ready for planting or paving.
Our Process: Engineering Meets Execution
01
Site Analysis
We evaluate grade, soil type, water flow, and potential risks to ensure the site supports a lasting, well-planned installation.
02
Design Agreement
Our planning proposal (3% of the projected job cost) includes contour strategy, drainage plans, and tie-in recommendations, credited back if we build.
04
Fixed-Cost Proposal
Transparent, complete pricing for all prep, excavation, pipework, and finish grading.
03
Plan Finalization
We finalize slope direction, pipe runs, and drainage points. If engineering or township review is required, we handle coordination.
05
Execution
Your crew manages the install from start to finish. No subcontracted unknowns, no corners cut.
“One of the things we appreciated most about working with Mark was his ability to seamlessly integrate both form and function into his designs. Since he spent so many years doing the actual work he also designs, he was able to consider both the aesthetic appeal of the design as well as the practical aspects of the project. This is a rare quality to find in a designer, and Mark excels at it.”

Frequently Asked Questions
-
Brandywine Designs provides landscape grading and drainage design and installation as a foundational service that protects the long-term performance of every other element in the outdoor environment, including patios, retaining walls, planting beds, and structures. Grading work involves reshaping the terrain to direct water away from structures, create level usable areas, and establish proper flow across the site, while drainage installations capture, redirect, or disperse water through systems designed for the specific conditions of each property. Both services are addressed during the design phase of any project where site conditions warrant it, and are also available as standalone engagements for properties experiencing active water management problems.
-
Drainage failures are responsible for some of the most common and costly landscape problems, including heaving patio surfaces, eroding planting beds, saturated lawns, and structural damage to retaining walls and foundations. In southeastern Pennsylvania and Delaware, where clay soils limit natural infiltration and seasonal precipitation is significant, drainage design is not optional on sites with any meaningful grade complexity. Brandywine addresses grading and drainage proactively at the design stage rather than treating it as a repair task, because retrofitting drainage into a finished landscape is consistently more expensive and disruptive than building it in from the start.
-
Brandywine Designs takes on grading and drainage projects as standalone engagements when the site issue is clearly defined and the scope does not require full landscape redesign. These projects follow the same design-first, fixed-cost process as all Brandywine work, beginning with a site assessment and design proposal that maps out the problem, evaluates solutions, and produces a clear plan before any excavation or installation work begins. Clients in the Main Line and Brandywine Valley who are dealing with water pooling, erosion, or persistently saturated areas on their property can start with a consultation to determine whether a standalone drainage solution addresses the issue or whether broader site work is warranted.
