How Landscape Design and Retaining Walls Work Together on San Anselmo, CA, Hillside Properties
San Anselmo sits in the shadow of Mt. Tamalpais, where the terrain rises and falls with the kind of character that makes Marin County so beautiful and so challenging. Hillside lots, sloping yards, and uneven grade changes are part of the fabric here. For homeowners looking to make the most of that terrain, the conversation almost always leads to retaining walls.
But a retaining wall designed in isolation often looks and feels like exactly that: a wall that was added to the property rather than one that belongs there.
That is why Heritage Landscapes approaches retaining walls as part of a complete landscape design, never as a standalone project.

When the Wall Is Part of the Plan
A retaining wall designed alongside the rest of your landscape becomes more than a structural element. It shapes how the entire property feels and functions.
When we design retaining walls as part of a broader landscape overhaul, we account for how every element relates to the wall and to each other:
Grading and drainage are addressed holistically, so water moves through the site correctly rather than pooling against the wall or eroding the landscape
Plantings above and below the wall are selected to complement the materials, soften the edges, and reinforce long term slope stability
Patios, walkways, and stairs are designed in conversation with the wall so transitions between levels feel intentional rather than abrupt
Lighting can be integrated into or around the wall to highlight texture and guide movement through the landscape after dark
This kind of integration is only possible when the retaining wall is part of the design from the beginning, not added after the fact. The result is a wall that does not just hold the slope. It settles into the landscape as if it has always been there.

Why San Anselmo Properties Require This Approach
San Anselmo's terrain is defined by slopes, Marin clay soils, mature tree roots, and seasonal rain that puts serious pressure on any structure holding back earth.
Marin clay expands when wet and contracts when dry, creating ground movement that a poorly designed wall cannot absorb. Mature oak and bay laurel roots can shift stonework over time. And the winter rains that move through this part of the county will overwhelm drainage that was not planned as part of the larger site design.
A wall that does not account for these conditions may hold for a while. But water pressure, soil movement, and root intrusion will find every weakness in a wall engineered without the full picture.
Heritage Landscapes has worked in this landscape for over 35 years. We know the soil, the light, the grade, and how these sites change with the seasons.
Design First, Build Smart, Care Always
Heritage Landscapes partners with landscape architects, engineers, and builders to deliver outdoor spaces that are as thoughtful below the surface as they are beautiful above it.
Every retaining wall we build is part of a larger vision for the property. We handle design, construction, and long-term maintenance as one integrated process, because a landscape that belongs in its surroundings requires that level of care.
