Corte Madera Concrete serves San Anselmo homeowners with concrete retaining walls, driveways, patios, steps, and foundations. We know the hillside lot conditions, the seasonal clay soil movement, and the Marin County permit process that apply here. We reply within one business day, pull permits, and build structural concrete that handles wet winters and sloped terrain for decades.
Hillside lots throughout San Anselmo need walls that hold back saturated clay soil through wet Marin winters without cracking, tipping, or failing. Older walls made of railroad ties or dry-stacked stone are past their service life and are often the first thing to go in a heavy rain year. Our concrete retaining walls are built with proper drainage, sized footings, and poured concrete that handles the load year after year.
Many homes in San Anselmo are set back from the street on sloped lots, with front entry stairs that drop several feet. When those steps crack, heave, or become unstable, they are a daily hazard for anyone using them. We replace failing entry stairs with properly footed concrete steps built to remain level and safe on sloped terrain through seasonal ground movement.
San Anselmo's older Craftsman and bungalow neighborhoods have narrow lots with driveways that were often built to a single-car width in the 1940s and 1950s. Many are cracked, tilted, or draining toward the house. We replace them with properly graded slabs that direct water away from the structure and are built to handle the seasonal clay soil movement that damages improperly prepared surfaces.
Flat patio space is valuable on a hillside lot, and concrete is the most durable surface for it. Unlike wood decking, a concrete patio does not rot, warp, or require annual sealing. On terraced hillside lots in San Anselmo, a patio slab also serves as a level platform that reduces erosion and stabilizes the terraced area through wet season runoff.
Whether you are building a new fence, adding a deck, or installing a garden wall, the footing determines whether the structure stays plumb over time. On San Anselmo's hillside lots, footings need to go deeper than flat-lot standards to account for slope loading and clay soil seasonal movement. We size and pour footings to match the actual site conditions, not a generic template.
Older homes in San Anselmo built in the postwar era sometimes sit on foundations that have settled or shifted with decades of clay soil movement. When a foundation needs replacement or a new slab is required for an ADU or addition, we handle the pour to current California code with reinforcement designed for seismic zone and soil conditions in this part of Marin County.
San Anselmo sits in the Ross Valley, flanked by hillsides on both sides of the valley floor. The flat downtown area along Sir Francis Drake Boulevard sits near San Anselmo Creek, which has a documented history of flooding in heavy rain years. Properties near the creek have drainage concerns that affect how any concrete flatwork needs to be graded. The hillside properties above town have a completely different set of issues: slope loading on walls, steep driveway grades, and footing requirements that go deeper than flat-lot norms.
The housing stock here is older than most Marin cities. San Anselmo developed early, and many of its residential neighborhoods have Craftsman bungalows and Victorian-era homes built in the early 1900s. That means a lot of the original concrete around these homes - driveways, patios, retaining walls - is 60, 70, or even 80 years old. Surfaces that old are not candidates for patching; they need replacement. A contractor who understands period construction in this area will also recognize when an old wall or slab is hiding a drainage problem that needs to be solved before new concrete goes in.
Marin County's wet winters are the stress test for everything concrete in this area. The soil absorbs rain from November through March, swells against every structure sitting in or on it, and then shrinks again through the dry months. That cycle is why wall drainage is non-negotiable on hillside lots and why base compaction is critical even on flat-lot work. Contractors who do not account for this typically produce work that looks fine for the first year or two and then starts moving.
Concrete work in San Anselmo goes through the Marin County Community Development Agency rather than a city building department - San Anselmo is an unincorporated town and county jurisdiction. We are familiar with that process and pull permits through the county regularly. Understanding the county's permit requirements, plan check workflow, and inspection scheduling is something that comes from doing it repeatedly, not from reading about it.
San Anselmo is a town most Marin residents know well - the antique shops and restaurants along Sir Francis Drake Boulevard, the creek that runs through the middle of town, the wooded hillside neighborhoods above the valley floor. We have worked on properties across this area, from flat in-town lots on older residential streets to steep hillside sites where equipment access has to be planned carefully before the crew arrives.
We also serve Fairfax, CA just to the west and San Rafael, CA to the east. If your project spans multiple properties or jurisdictions, we have the familiarity with this part of Marin County to handle it without friction.
We respond within one business day and schedule a visit to your property. For hillside jobs we assess access, slope, drainage, and existing soil conditions before quoting - no two hillside lots in San Anselmo are the same. The written quote covers every phase of work.
We file permits through the Marin County Community Development Agency. County review typically takes one to three weeks depending on project type and current workload. Structural wall projects may require engineer drawings, which we coordinate on your behalf.
For retaining walls, this step includes excavating for the footing, placing drainage gravel and perforated pipe behind the wall location, and setting forms. This is the most time-intensive step and the one that determines long-term performance.
Concrete is poured and left to cure. The county inspector signs off on the finished work. You receive a copy of the completed permit, which documents that the work was done to code - important for insurance and future property transactions.
We serve San Anselmo homeowners with written estimates, Marin County permits, and work that holds up on hillside lots and flat-lot properties alike. Call us or fill out the form and we will respond within one business day.
(628) 212-4120San Anselmo is a town of roughly 12,000 residents in the Ross Valley area of central Marin County. It is an unincorporated town, which means county government handles planning and permits rather than a city administration. The town is widely known as the Antique Capital of Northern California, and the commercial district along Sir Francis Drake Boulevard draws visitors from across the Bay Area. The creek that runs through the center of town, San Anselmo Creek, is a visible feature of the community and contributes to the town's character - and its occasional flooding history during wet winters.
The residential character of San Anselmo is defined by its early 20th-century housing stock. Craftsman bungalows, Colonial Revival homes, and older Victorian-influenced houses are common on the tree-lined residential streets near downtown. Above the valley floor, hillside neighborhoods have more secluded properties on larger lots with mature oak and bay laurel trees. The combination of old housing, hillside terrain, and creek-adjacent lots makes San Anselmo one of the more complex areas in Marin County for concrete and foundation work.
We work throughout the Ross Valley and neighboring communities, including Fairfax, CA to the west and San Rafael to the east. If you are in Ross, Kentfield, or any of the surrounding unincorporated Marin areas, give us a call - we serve this part of the county regularly.
