Homeowners often call asking for a rain garden or a buried drain as if those were the first decisions.
They are not. The first decision is how water already moves across the lot. Clay soils, short slopes, and tight side yards around Pittsburgh can push roof and yard water into the same low corner. The right fix follows that path. The wrong product label can move the wet spot without solving it.
Eichenlaub designs drainage and sustainable landscape features as part of broader landscape design and build work. We also maintain finished landscapes through residential landscape management. Drainage choices have to stay serviceable after install day.
Start with observation after a real rain before you commit to a garden basin or a pipe.
Watch where water enters, slows, and stops
Walk the property during or right after a storm.
Mark downspout outlets, driveway runoff, neighbor discharge if it crosses the line, and the lowest planted or turf area that stays soft. Note how long water stands. A spot that clears in an hour is a different problem from a corner that stays saturated for days.
Surface runoff that sheets across a lawn may be a candidate for a shallow rain garden or grade correction. Concentrated roof water from several downspouts may need a different collection and outlet plan before any planting basin is dug.
Photograph the wet areas with a timestamp. Memory compresses storms. Photos give the design visit a clear starting record.
Test whether the soil can absorb what you want to plant
A rain garden only works if water can move into the soil at a useful rate and if overflow has somewhere safe to go.
Western Pennsylvania clay often infiltrates slowly. That does not ban rain gardens, but it changes depth, soil mix, plant palette, and overflow design. A buried drain may be the better primary tool when water must be carried to a legal outlet and the soil cannot accept the volume near the house.
Ask for both options to be evaluated against the same site notes. Product preference should not outrun infiltration, setbacks, and outlet reality.

Map overflow before you dig the pretty part
Every basin and every pipe needs a failure plan.
Where does water go when the next storm is larger than the design storm in your head? Overflow toward a foundation, a neighbor, or a sidewalk is not an acceptable surprise. Draw the overflow route on the same sketch as the proposed rain garden or drain line.
Also mark future access. A buried line that cannot be found later becomes a mystery wet spot for the next owner. Cleanouts, marked routes, and a simple as-built note belong in the property file.
Keep planting and maintenance inside the drainage decision
A rain garden is a working feature, not only a plant bed.
It needs the right plants for wet-to-dry swings, mulch habits that do not smother inlets, and a maintenance plan for sediment and weeds. A buried drain needs outlet checks and a clear boundary so later landscaping does not bury cleanouts.
If you already use our Outdoor Living Studio for patio and material decisions, bring drainage into that same planning pass. Hardscape and water paths should be designed together. Visit the Outdoor Living Studio and browse the portfolio for projects where grade and outdoor living stay connected.
Coordinate with hardscape and outdoor living early
Patios, walks, and walls change how water moves. If a new outdoor living area is planned, design the drainage path before stone closes the ground. Sleeves, cleanouts, and overflow routes are cheaper to place while the site is open.
Bring the same sketches to irrigation planning so spray zones are not fighting a new basin or swale. Irrigation services and drainage should share one property drawing when both are active.
Do not bury the decision under a plant order
Ordering rain-garden plants before you know the water path is how beds drown or stay dry in the wrong week. Confirm inlet locations, soil response after a storm, and where overflow goes if the basin fills. Only then choose plant lists and mulch habits that match wet-to-dry swings on a Pittsburgh clay lot.
If a buried drain is the better fit, write cleanout locations into the property file and into any later maintenance agreement. Future planting crews should not hide those access points under new shrubs. Pair drainage notes with lighting cable routes when both systems share a bed so a night-aim visit does not discover cut conduits.
What to send before a drainage consult
Share storm photos, downspout locations, a rough sketch of soft ground, and any prior pipe or French drain work you know about. Note basement symptoms separately from yard wetness so the team does not blend two problems into one assumption.
