8.4 Planting plan
The planting plan is provided. Trees will be planted at grade in holes 1-2 times the width of
the container or root ball. The mulch will be applied around each tree 2-4 inches deep in a
two -foot diameter around the tree with an edge to retain water. Rootbound trees will be out
with sharp shears on the bottom in an x pattern to promote root growth. Four cuts will be
made vertically to allow roots to spread. Trees will be thoroughly watered in after
installation.
Shrubs will be installed in a similar manner.
The species selected are typical native northwest species that usually survive our summers;
however, it may be necessary torirragate-during-the_first two years to ensure survival. The
watering will be the minimal necessary to avoid creating erosion.
l,
All retaining walls will be planted wit,� ki.nnikinigtto provide screening from the walls.
The first 15 feet along the creek will be planted with shrubs like Red osier dogwood, Pacific
ninebark and Twinberry to provide erosion protection and structure over the creek which will
provide allochthonous inputs like macroinvertebrates for the fish below.
The second thirty feet will be primarily trees like Sitka spruce, Western hemlock and
Western red cedar and Red flowering currant to provide shade that will attenuate
temperatures and eventually shade out the invasive species that have become prevalent in
the area.
The remaining area near the walls will be planted with groundcover (Salal and Roses) for
erosion protection. _-

8.4 Performance Standards and Monitoring
The site will be monitored for five years with the as -built as Year 0. Photo points will be
established in 2 points that capture the overall condition of the planting area. Monitoring will
begin in the spring following the installation of the plants. Year 1 will require 100 percent
survival. Year 2 must have 100 percent survival of planted native plants Years 3-5 will have
Exhibit B-4
Land Services Northwest 19
December15,2020
an 80% survival rate. If the survival rate is not met in the final year, the deficit will be
replanted, and the site will be monitored for 1 more year. The survival percentage will
include 10 percent of any native non-invasive volunteers. Monitoring will occur each spring
after the plants have sprouted leaves. Management will require prior removal of any
blackberries, scotch broom or holly or other invasive plants in the planting area and
replacement of any dead plants as required to meet the performance standards. A report
of management actions and photos of the area will go to the City of Edmonds Development
Center within a month following each site monitoring event.
The invasive removal area will be monitored as well. The invasive removal area will have
any non-native blackberries grubbed out. Holly will be cut down and any other invasives
encountered will be removed by hand.
9.0 CONTINGENCIES
The City will be consulted on any contingency measures that are developed. The report will
be in an email by the applicant and will include pictures that illustrate the condition of the
mitigation site.
Contingency/maintenance activities may include, but are not limited to;
1. Replacing plants lost to vandalism, drought, or disease, as necessary;
2. Irrigating the enhancement areas only as necessary during dry weather if plants appear
to be too dry, with a minimal quantity of water;
3. Remulching areas to protect from dry weather
4. Providing protection from rodents
10.0 CONCLUSIONS
Development activities accidently occurred in the riparian buffer when the applicant installed
his steps, retaining walls and other landscape amenities. A geotechnical report has shown
that these structures can safely remain without destabilizing the slopes and causing
damage to the property. The applicant has carefully considered the best options for
revegetatfng the slopes with vegetation that is appropriate for limiting erosion and adding
stability to the slope. This restoration will provide benefits to the area in many different
ways but most importantly, it will maintain the functions and values of the stream for the
citizens of Edmond.
