Lower Amazon Creek <br /> b) Guidelines for Tree and Shrub Plantings <br /> Notes: <br /> • Plan for a 400' section <br /> • To protect the integrity of the levees, all trees should be removed when they reach a <br /> height of 20'. Large trees may fall, damaging the levee and placing nearby residents at <br /> risk of flooding. Alternatively, planting native trees that <br /> g Y� p g grow no higher at <br /> maturity than 20', such as flowering dogwood, cascara, chokecherry, Pacific madrone. <br /> • Shrub planting may occur on the lower and upper banks, but the top of the levees should <br /> remain unplanted to allow maintenance and inspection access along the channel. <br /> • Plants not planted in clusters should be evenly spaced along the whole section. <br /> • If a species is included in more than one planting zone, a single cluster across both zones <br /> can be displayed. <br /> • To allow adequate conveyance, NO plants should be near bridges. Leave a distance of <br /> approximately one bridge width on either side of each bridge unplanted. Leave 20 feet <br /> unplanted centering on each outfall. <br /> • This section should be more open, with no big trees. <br /> Plants Total Number Plants Planting <br /> Latin Name Common Name Q of Plants spacing Zone <br /> Both per within <br /> Banks Clusters Clusters <br /> Amelachier alnifolia Western 4 - 1 No) <br /> serviceberry <br /> Rosa nootkana Nootka rose 10 5 -10 5' 2 & 3 <br /> ___._...... <br /> Salix hookeriana Hooker's willow 15 - - 3 <br /> Salix lucida ssp. lasiandra Pacific willow 30 - - 2 <br /> Salix scouleriana Scouler willow 15 3 <br /> - - <br /> Salix sitchensis Sitka willow 15 <br /> ' 3 <br /> Sp ir a douglasii Douglas spirea 10 5 -10 5' 2 & 3 <br /> (z ' Symphoricarpus albus Snowberry 15 5 -10 5' 2 & 3 <br /> Total 114 <br /> c) Planting diagram <br /> Top of NO TREES OR SHRUBS <br /> Bank (1) <br /> Upper Pacific willow / Western Serviceberry / Nootka rose / Douglas <br /> Bank (2) spirea / Snowberry <br /> J <br /> 30 <br />
