HomeMy WebLinkAbout7k_WatercoursePlanting_12661.pdf WATERCOURSE PLANTING PLAN
The Watercourse Planting Plan for Boulder Creek Subdivision (Sheet l of 1) shows the
location of 18 planting clusters, consisting of 33 trees and 79 shrubs, for a total of 112 plants.
Eleven of the clusters are dominated by wetland plants and seven of the clusters are dominated by
upland plants. The species, quantities, recommended plant sires, and diameter at maturity of
individual woody plant materials are included on the table shown on Sheet I of 1 for the Boulder
Creek Subdivision. The woody plants will be irrigated and caged for protection from wildlife
browse. The tree density for Boulder Creek Subdivision was greater than the 27 trees required
for the length of the watercourse within the subdivision. The shrub density was reduced slightly
from 82 based on the presence of the existing woody overstory located between Sherwood Way
and Oak Street and north of Annie Street.
The native streambank and upland seed mixes shown on Sheet 1 of 1 for Westbrook and
Boulder Creek Subdivisions will be planted in areas disturbed during construction or existing
bare areas. The native streambank mix will be seeded in areas where the groundwater table rises
to within 12 inches of the ground surface during the growing season, which coincides with areas
delineated as wetlands. The native upland mix will be planted in the remaining disturbed areas.
