SUBJECT: Wetland Buffer Mitigation Plan Review for Jurgens Property
2301 Jones Ave. NE, Parcel 334450-0210
Renton, WA
Dear Steve:
I have reviewed the wetland buffer mitigation planting plan that you have prepared
for your proposed house expansion. Due to the location of the existing structure, the
addition must be constructed within the wetland buffer to the north of the house. The
area of the proposed expansion currently consists entirely of existing gravel parking
and no significant vegetation would be removed as part of your proposed project.
The buffer area associated with your proposed expansion does not currently
provide any functional benefit to the wetland located off-site to the north. As
part of the project you are proposing to plant a variety of native tree and
shrub species within the buffer along the north property line to increase the
plant species and structural diversity of the buffer. These plantings would
provide a physical and visual screen to the wetland from the residence and
would increase the habitat and protection functions of the buffer over current
conditions.
In addition, since there should be no increase in pollution generating
surfaces associated with the project, there are no anticipated hydrologic
impacts to the wetland.
Implementation of the mitigation plan as proposed would therefore increase the
functions provided by the buffer over current conditions and there would be no net
loss of wetland functions or values as a result of the project.
