Can a rain garden or stormwater system be integrated with a pool project?

The Short Answer

Yes — and in many Maryland jurisdictions, it’s not just possible but required. Adding a pool and deck significantly increases impervious surface on a property, which triggers stormwater management requirements in Anne Arundel County and other Chesapeake Bay watershed jurisdictions. Rather than treating this as a compliance hurdle, Wade designs rain gardens and permeable hardscape as integrated parts of the pool project — satisfying county requirements while adding landscape features that look intentional and support Bay water quality.

Why Stormwater Matters for Maryland Pool Projects

A pool deck can easily add 500–1,500 square feet of new impervious surface, which frequently triggers stormwater management requirements in Anne Arundel, Howard, and other Bay watershed counties. Wade designs stormwater management into the overall landscape plan from the beginning — not as an afterthought after permits come back with conditions.

What a Rain Garden Does

A rain garden is a planted depression positioned downslope from the impervious surface that collects and slowly absorbs stormwater runoff. In a pool context, it captures water that sheets off the deck during rain events. It’s planted with deep-rooted natives that absorb water quickly and tolerate both temporary flooding and dry periods. A rain garden doesn’t stay wet permanently — it absorbs within 24–48 hours and returns to dry planted conditions. Once established (1–2 growing seasons), a native rain garden needs no irrigation and provides seasonal color from native wildflowers and grasses.

Permeable Hardscape as a Stormwater Strategy

Permeable paver systems — concrete pavers with wider joints filled with crushed stone rather than polymeric sand — allow rainwater to infiltrate through the deck surface itself. Wade holds ICPI certification which includes permeable interlocking concrete pavement (PICP) systems. For pool decks near the Bay or in critical area buffers, permeable systems can eliminate or reduce the rain garden requirement entirely depending on impervious area calculations.

Chesapeake Bay Native Plants for a Poolside Rain Garden

• Switchgrass (Panicum virgatum): Deep roots, handles wet-dry cycles, excellent fall color
• Cardinal flower (Lobelia cardinalis): Vivid red blooms, attracts hummingbirds, tolerates temporary flooding
• Joe Pye weed (Eutrochium purpureum): Tall late-summer bloomer, excellent background screening
• Blue flag iris (Iris versicolor): Tolerates wet edges, spring bloom color
• Virginia sweetspire (Itea virginica): Compact shrub, exceptional fall color, handles wet-to-dry swings
