Tree Mitigation Planting Guide: Meeting Municipal Permit Replacement Requirements on the Peninsula

In Redwood City, removing a protected tree (such as a native oak with a circumference exceeding 38 inches) requires replacing it with one or more specimen trees. The standard municipal condition requires planting a minimum 24-inch box tree or two 15-gallon trees on the property. The replacement species must be chosen from the city's approved climate-appropriate list, with strong preference for native California shade species.

City arborists favor species that provide long-term canopy benefits and drought tolerance: 1) Coast Live Oak (Quercus agrifolia) – Outstanding wildlife value, deep root system, and high fire resistance when maintained. 2) Valley Oak (Quercus lobata) – Majestic spreading deciduous shade tree ideal for deep loam soils. 3) Western Redbud (Cercis occidentalis) – Compact flowering native suited for courtyard and patio microclimates. 4) California Sycamore (Platanus racemosa) – Fast-growing native shade tree tolerant of heavy clay soils.

What if your residential lot is already densely covered with structures, hardscape, or existing canopy, leaving no viable physical space to plant a 24-inch box shade tree? Most Peninsula municipalities (including Redwood City, San Carlos, and Menlo Park) provide an 'In-Lieu Tree Replacement Fee' option. Homeowners pay an established municipal fee (typically $500 to $2,500 per required replacement tree) directly into the city's Urban Forestry Fund, which the city uses to plant trees in public parks and parkway medians.

Simply putting a tree in the ground does not close your permit. Most cities require an ISA Certified Arborist to submit a formal Planting Affidavit or Verification Letter with dated photographs, nursery purchase tags confirming container size, species identification, and verification that the root flare was planted at proper grade with double-stake support and a watering basin. Honey Bear Trees handles this turnkey certification process.
