s t r e e t tree soils s h r u b s and groundcovers To improve the health and life expectancy of the street trees, structural soil is recommended adjacent to all tree pits under the flexible zones, where the concrete unit pavers will also allow some air to pass through to the soil and roots. Structural soil can be compacted to 95% of dry density to support sidewalks and other paved areas, but will allow tree roots to extend through it and under the paved areas. Structural soil mixes typically comprise about 20% clay loam soil mixed with 80% 1 to 3/4-inch angular gravel, which forms voids for the soil and roots. Since structural soil has 80% less soil per cubic foot than regular soil, approximately five times as much volume of structural soil should be used to provide each tree with an adequate growing medium. The structural soil zone should be at least 36” deep. The sidewalk extensions at tree planters, and individual planting strips will be planted with ornamental plants or groundcovers to provide visual interest, reinforce the separation between the street and the sidewalk, and to help mitigate the impacts of traffic on pedestrians. Design criteria for selection of ornamental planting include: • Low maintenance. • Hardy and able to withstand occasional foot traffic. • Bright color, preferably in all seasons. • Low in height to allow drivers and pedestrians to see one another, particularly at intersections. • Seasonal color. Rosmarinus officinalis, Rosemary Lavandula angustifolia, Lavender Calamagrostis arundinacea ‘Karl Foerster’, Feather reed grass Equisetum hyemale, Horsetail Planting soil should be used in the tree pit itself, where 95% compaction is unnecessary. Ornamental shrubs and groundcovers to be considered in the detailed design phase include: • Cistus x purpureus ‘Brilliancy’, Pink rockrose • Lavandula angustifolia, Lavender Cistus x purpureus ‘Brilliancy’, Pink rockrose Phormium tenax, New Zealand flax Miscanthus sinensis, Maidenhair grass Mahonia nervosa, Longleaf mahonia • Festuca ovina ‘Glauca,’ Blue fescue • Pennisetum alopecuroides, Fountain grass • Phormium tenax, New Zealand flax • Rosmarinus officinalis, Rosemary • Miscanthus sinensis, Maidenhair grass • Calamagrostis arundinacea ‘Karl Foerster’, Feather reed grass • Gaultheria shallon, Salal Gaultheria shallon, Salal Miscanthus sinensis, Maidenhair grass Festuca ovina ‘Glauca,’ Blue fescue Berberis thunbergii, Japanese barberry • Viburnum davidii, Viburnum • Berberis thunbergii, Japanese barberry • Equisetum hyemale, Horsetail • Arctostaphylos uva ursi, Kinnikinnick • Cotoneaster dammeri, Bearberry cotoneaster • Ceanothus gloriosus ‘Heart’s Desire”, Wild lilac Viburnum davidii, Viburnum Ceanothus gloriosus ‘Heart’s Desire”, Wild lilac Arctostaphylos uva ursi, Kinnikinnick Cotoneaster dammeri, Bearberry cotoneaster Woodinville, Washington 41
