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, consider planting native trees that 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 />c) Planting diagram <br />Top of I NO TREES OR SHRUBS <br />Bank (1) <br />Upper Pacific willow / Western Serviceberry / Nootka rose / Douglas <br />Bank (2) 1 spirea / Snowberry <br />[GPI] <br />Plants <br />Total <br />Number <br />Plants <br />Planting <br />Latin Name <br />Common Name <br />Qty <br />of Plants <br />spacing <br />Zone <br />Both <br />per <br />within <br />Banks <br />Clusters <br />Clusters <br />Amelachier alnifolia <br />Western <br />- <br />- <br />se <br />4 <br />1 <br />Rosa nootkana <br />_ _........ �.. - -- ..._- ....._....._._........_.. <br />No otka rose <br />_.... <br />10 <br />5 -10 <br />5' <br />2& 3 <br />Sa — .... - -- -- ._ ._.....----- .._..........._.. <br />_............_... <br />-_ <br />Sa l ucida ssp. lasiandra <br />_— .......... <br />Pacif willo <br />_.- ....__ - <br />30 <br />_ <br />- <br />- <br />_— - - - - -- - -.. <br />2 <br />Sal scouleria <br />_... _ .... _ _ <br />Scoul willow <br />15 <br />- <br />- <br />3 <br />W <br />Salix sitchensis <br />- .._..__........ -- .............. _ <br />- <br />Sitka willow <br />- ....-- ..__....._...- - <br />15 <br />_ <br />- <br />_ ............_ <br />- <br />_ .. <br />3 <br />—_ <br />�irea douglasii <br />_ - -.— ............- - <br />Douglas spirea <br />- - ._................__— <br />10 <br />_....._.._...... <br />5 -10 <br />5' <br />- <br />2 & 3 <br />Symphoricar us albus <br />Snowberry <br />15 <br />5 -10 <br />5' ._ <br />2 & 3 <br />Total <br />114 <br />c) Planting diagram <br />Top of I NO TREES OR SHRUBS <br />Bank (1) <br />Upper Pacific willow / Western Serviceberry / Nootka rose / Douglas <br />Bank (2) 1 spirea / Snowberry <br />[GPI] <br />
