Retaining walls in Saco, Maine.
Much of Saco is gentle ground, but the land drops toward the Saco River along its whole run past downtown, and brooks such as Goosefare Brook cut their own small valleys on the way to the bay. Those banks, plus the sloped lots in the older neighborhoods near Main Street, are where a wall earns its keep.
We build granite veneer walls, natural boulder walls and segmental block walls, each engineered for drainage and frost. In Saco, two local questions come before the first course is set: what soil is behind the wall, and whether the wall sits in a regulated corridor.
A wall is a structure under the corridor act
The Saco River Corridor Commission lists walls among the structures that need its permit inside its jurisdiction, which covers land within 500 feet of the river and up to 1,000 feet in the 100-year floodplain. The same rules bar cutting trees in the first 75 feet inland from the shoreline except by selective cutting, and never to open a view. A wall meant to terrace a riverbank is planned so that the grading behind it does not strip the vegetation the Commission wants kept.
Twenty municipalities along 130 river miles share this Commission, so its rules are the same in Saco as upriver, but the city's own code office still handles local permits alongside it.
Why drainage decides wall life here
The NRCS describes the Buxton soil series, formed in glaciomarine deposits in coastal lowlands and river valleys, as moderately well drained with slow to very slow permeability in its lower layers and signs of saturation within about 24 inches of the surface. Soil like that stays wet behind a wall, and wet soil pushes harder and heaves in a freeze.
So a Saco wall gets a free-draining gravel backfill, a perforated drain at the base with a real outlet, and a footing set on compacted material below the loam. Granite veneer entry walls and boulder terraces follow the same rule: the drainage is built first and the face goes on last. That is what lets a wall paid for once stand for decades rather than lean after a few winters.
Boulder walls suit the natural look of lots near the Saco Heath and the wooded side of the city, while block walls fit the tighter, squarer lots of the older neighborhoods. On a sloped lot where a new patio or driveway needs level ground, the wall and the grading are drawn together so runoff from the new surface has a planned path around or through the wall instead of piling up behind it.

How we handle retaining walls
Whether it is a granite veneer entry wall with lantern pillars, a terraced boulder slope or a structural block wall behind a new build, we engineer for drainage and frost so the wall you pay for once stands for decades.
