Mill Valley yards are rarely flat and rarely sunny all day. Homes climb the lower slopes of Mount Tamalpais on narrow, winding streets, with redwoods towering over many lots and fog rolling up the valley on summer mornings. Backyards often drop away steeply or rise straight up behind the house, and every winter storm sends water down those slopes toward foundations, decks and walkways. Add deer, deep shade and limited access for equipment, and a Mill Valley yard takes more planning up front than a flat lot in the valley towns.
We build Mill Valley yards around the slope and the shade. On many properties, that means retaining walls and terraces to turn a hillside into usable ground, with drainage built in so water moves around the house instead of through it. Under the redwoods, it means picking plants that actually grow in dry shade, and laying out paths and steps that make a steep lot easy to get around.

Planting Under the Redwoods
Redwoods give Mill Valley its character, and they shape every yard they stand in. Their roots spread wide and stay shallow, so the ground underneath is crowded and dry even though the air feels damp. The fallen needles build up a thick layer of duff, and the shade is deep enough that sun-loving plants stretch, flop and give up. The trick is to work with the tree instead of against it. Ferns, native huckleberry, redwood sorrel, wild ginger and other woodland plants thrive in those conditions with little care, and they stay green through the dry months without much summer water. We plant them in pockets between roots instead of tilling, which protects the tree and saves a lot of digging. Patios and paths near redwoods need careful layout too, with flexible surfaces like gravel or stone set on sand so roots can grow without heaving them. Similar woodland conditions show up in shaded canyons farther up the county, including parts of Larkspur.
Building on Mill Valley's Steepest Streets
Access shapes every project here. Many streets in Mill Valley, Homestead Valley and Tam Valley are narrow, steep and lined with parked cars, and plenty of homes are reached by a long stairway climbing up from the street or dropping down to the front door. That means smaller equipment, materials staged carefully and sometimes carried in by hand, and a schedule planned around tight parking. It also changes the design. On a steep lot, every wall, step and path has to deal with water coming from above, so drainage gets built into the walls themselves and into the base of every terrace. Steps need consistent heights and good lighting for nighttime use, and landings give you places to stop and sit. Done right, a hillside lot that felt like an obstacle course becomes a series of garden rooms stepping down the slope, each with its own view. Where runoff is already causing trouble, we start with yard drainage before planning anything else.
Mill Valley Landscaping Questions
Plants from the redwood forest itself. Western sword fern, redwood sorrel, wild ginger, evergreen huckleberry and native iris all handle the dry shade and acidic ground under redwoods, and they look natural in Mill Valley's canyons. Most lawn grasses and sun-loving shrubs struggle there no matter how much you water them. We plant in small pockets between roots rather than tilling, so the tree isn't damaged and the new plants get a head start.
Yes, with care. Redwood roots run wide and shallow, so a poured slab close to the trunk is likely to crack and can harm the tree. Gravel, decomposed granite or flagstone set on sand work much better, since they let water reach the roots and can shift a little as roots grow. We keep excavation shallow inside the root zone and lay out the patio so the heaviest digging happens farther from the trunk.
