Field intelligence
What does RNR look at before retaining walls?
Retaining walls around Sonoma, Napa, and Marin are usually about grade control, erosion, drainage, and usable space. Some walls may require engineering, permits, or local review depending on height, location, load, and site conditions.
What does RNR check on the walkthrough?
- Slope, soil movement, wall height, surcharge, drainage paths, and erosion signs.
- Access for excavation, materials, compaction, wall drainage, and cleanup.
- Nearby structures, fences, utilities, trees, driveways, and property lines.
- Whether local permit, engineering, or specialty review may be needed before work.
Best-fit clients
- Hillside homeowners dealing with erosion, sliding soil, or limited usable yard space.
- North Bay properties needing terraces for planting, access, or outdoor rooms.
- Commercial sites with slopes, service areas, or failing landscape edges.
- Clients who want wall work coordinated with drainage and landscape construction.

Call RNR or request a free estimate. The team serves Petaluma, Penngrove, Santa Rosa, Sonoma County, Napa County, and Marin County.
When should you choose another first step?
- A single cleanup visit with no design, construction, drainage, planting, or maintenance decisions attached.
- Work that needs engineering, arborist, or permit review before a landscape scope can be responsibly priced.
- Projects where the owner already has final drawings and only needs a narrow specialty trade outside C-27 landscape work.
Common mistakes to avoid
- Treating retaining walls as an isolated task instead of reading the whole property first.
- Choosing materials before drainage, grade, base preparation, and irrigation are understood.
- Treating planting, hardscape, and maintenance as separate decisions when they affect each other.
- Starting construction without a clear phasing plan for budget, access, and cleanup.
Aftercare
How does retaining walls keep working after the visit?
RNR treats the follow-up conditions as part of the scope, especially when water, soil, grade, planting, or recurring maintenance will affect the result.
- Review watering, settling, drainage, and plant stress after installation.
- Plan mulch, pruning, irrigation tuning, and seasonal cleanup before the new landscape declines.
- Keep notes on materials, plant choices, and maintenance needs so future work stays consistent.
