Designing for Wind, Salt, and Erosion
Coastal properties in Maine offer stunning views, but they also come with unique landscaping challenges. Wind exposure, salt spray, and erosion from storms and runoff can damage plantings, degrade soil quality, and wear down hardscape elements. If you’re looking to design or upgrade your oceanfront landscaping in Maine, it’s important to build with resilience in mind. Here are our top tips for creating a coastal landscape that’s beautiful, durable, and functional.
1. Choose Salt-Tolerant and Wind-Hardy Plants
Many common plants struggle near the coast due to salt in the air and soil, as well as constant wind. Native and salt-tolerant plantings are the best solution for oceanfront homes in Maine.Some of our favorite hardy selections include:
Rosa rugosa (Beach Rose) – Thrives in sandy soil and handles salt spray well
Morella pensylvanica (Northern Bayberry) – Offers evergreen interest and erosion control
Juniperus virginiana (Eastern Redcedar) – A tough evergreen that anchors sloped coastal soils
Amelanchier (Serviceberry) – A native small tree that handles coastal conditions and provides four-season beauty
Look for low-maintenance coastal plants that support pollinators and provide year-round stability.For more ideas, check out our blog on Native Plantings for Maine Landscapes.
2. Use Strategic Windbreaks in Oceanfront Landscaping
Wind can dry out soil, damage leaves, and push over less-anchored plants. Shelterbelts or informal hedgerows made of hardy shrubs or staggered plantings can help reduce wind velocity without blocking your view.
Plant a mix of evergreen and deciduous species to maintain structure throughout the year. Space plantings to allow for air movement while filtering strong gusts. Avoid formal fences that can topple or channel wind in damaging ways. Softer, layered plantings often work better.
3. Manage Erosion with Grading and Groundcover
Steep coastal slopes and runoff from rainstorms can lead to soil erosion, especially where the soil is sandy or compacted. Proper grading, drainage design, and erosion-resistant groundcovers are essential. Install a mix of deep-rooted shrubs, perennials, and native grasses to stabilize hillsides.Use stone retaining walls or naturalistic terracing on steep grades to slow runoff.
Groundcovers like bearberry or creeping juniper can help anchor soil and reduce bare patches.Want more ideas? Read our guide on Grading and Erosion Control Tips.
4. Build Hardscapes with Coastal-Ready Materials
Materials in oceanfront landscapes need to withstand salt corrosion, moisture, and frequent freeze-thaw cycles. When installing patios, walkways, or retaining walls, choose products that are built to last. Granite and bluestone are ideal for patios and walkways due to their durability and appearance. Crushed shell driveways can complement the seaside aesthetic while promoting drainage.Avoid untreated wood near the coast. Choose composite materials or pressure-treated lumber rated for coastal exposure. If you’re debating gravel materials, our Pea Gravel vs Crushed Stone Comparison may help.
5. Plan for Drainage and Stormwater Control
Saltwater intrusion and heavy storms can overwhelm poorly planned landscapes. Make sure your design includes drainage solutions that protect your home and landscape investment. Dry creek beds, rain gardens, and bioswales can filter and redirect runoff.
Avoid impervious surfaces near the shoreline. Permeable pavers or gravel driveways are better suited. Consider drainage grading early in the design process to manage how water flows during storms or spring melt.
6. Keep Maintenance in Mind
Oceanfront landscapes often require more frequent inspection and seasonal attention. Salt buildup, wind pruning, and shifting soils can all impact how your yard looks and functions.
- Rinse off salt spray from sensitive plants during dry stretches.
- Replenish mulch in spring and fall to protect roots and suppress erosion.
- Prune wind-damaged branches and monitor plant health through all seasons.

Frequently Asked Questions
What plants do well near the ocean in Maine? Salt-tolerant natives like beach rose, bayberry, eastern redcedar, and creeping juniper are excellent choices. These plants are adapted to sandy soil, strong winds, and salt spray.
How do you prevent erosion on a coastal slope? Stabilize slopes with native grasses, deep-rooted shrubs, terraces, and natural stone walls. Grading and planting techniques should slow water runoff and hold soil in place.
Can salt damage patios and driveways? Yes, salt can degrade concrete and some pavers over time. Use coastal-rated materials like granite or bluestone, and avoid deicing salts when possible.
What groundcovers help prevent erosion near the shore? Bearberry, creeping juniper, and native sedges are excellent low-growing plants that spread well and anchor soil on sloped or exposed sites.

Shoreland zoning comes before the plant list
Most oceanfront properties in Maine sit partly inside the shoreland zone. Under Maine's Mandatory Shoreland Zoning Act, that zone generally extends 250 feet from the upland edge of coastal wetlands, which includes tidal areas, as well as from great ponds, rivers and freshwater wetlands. Towns administer it through their own ordinances, so the details vary from one town to the next.
Closest to the water is a vegetated buffer strip, where the rules are strictest. In general terms:
- Tree cutting is limited, and a stand of trees must be left in place rather than cleared
- Low vegetation and groundcover under about three feet must stay
- A footpath is allowed, but it must wind rather than cut a straight view corridor to the water
- Lower branches may be pruned for views, within limits
Earthmoving, new walls, patios and other structures near the water can also need permits, sometimes from the town and sometimes from the state. Before any clearing or construction, call your town's code enforcement officer; clearing done without approval can require a costly restoration planting.
Planting by salt-spray zone
Salt exposure drops sharply with distance and shelter, so plan in bands:
- Front line, facing open water: the toughest natives only, such as northern bayberry, Virginia rose, American beach grass on sand, and low junipers
- Second line, partly sheltered: eastern redcedar, serviceberry, chokeberry and native grasses
- Behind the house or a windbreak: most ordinary landscape plants
Wind shapes the front line as much as salt does. Plants there stay lower and denser, so choose low, spreading forms rather than expecting a tall screen to hold up. Our salt-tolerant plantings post lists more species by tolerance.
After a storm surge
When saltwater floods a lawn or bed, act on the soil, not the plants. Flush the area with several deep waterings of fresh water as soon as you can, or let heavy rain do it, so salt leaches below the root zone. Rinse salt off evergreen foliage. Wait until the next growing season to judge damage, since shrubs that brown after a surge often leaf out again in spring. Replace with tougher front-line species only where plants have truly died.
Erosion on the bank
Most bank erosion comes from runoff over the top of the slope as well as waves at the bottom. Direct roof and driveway water away from the bank edge, keep the buffer vegetated, and fill bare spots with deep-rooted groundcovers; see groundcovers for erosion control. Anything built at the toe of the bank or on a dune is regulated and needs to be discussed with the town first.
Getting a coastal plan together
Our landscape design service plans coastal properties around these constraints, and the coastal landscape design guide covers layout. We work on waterfront properties in Cape Elizabeth, Old Orchard Beach and along the Southern Maine coast.
