RE: Wetland review of 7490 East Grapeview Loop Road, Mason County Parcel
#122295002040
Dear Mr. Bovey:
This letter report discusses the wetland review completed at your request on a 0.27 acre
project site located northeast of Shelton, near Allyn in Mason County, Washington. The
field review was completed during two site visits, in March of 2009.
The purpose of this wetland review was to determine if any wetlands are present on or
near the project site which would be regulated by the Mason County Resource Ordinance,
Chapter 17.01.070. This review was requested in conjunction with the development of a
single family residence on the property. Mason County has determined that wetlands or
streams may be present on or near the project site, and may encumber the site with
wetlands or wetland buffer.
Site analysis was conducted by Mason County beginning in 2002, and continuing through
March of 2009. As part of that analysis, a letter dated March 4, 2009,prepared by Mr.
Allan Borden, Planner for Mason County, outlines the outstanding items remaining to
resolve wetland-related issues on the project.
Wetland determinations were made using observable vegetation,hydrology, and soils in
accordance with the Corps of Engineers 1987 Wetland Delineation Manual, and the 1997
Washington State Wetlands Delineation Manual.
The project site is located in the northeast quarter of Section 29, Township 22 North,
Range 1 West, W.M. The project area is made up of one tax parcel, Mason County parcel
#122295002040. The project site is roughly a rectangular shaped area located
approximately 1 mile south of the town of Allyn.

The project site is bounded by single family residential development on the north and
south, and by Grapeview Loop Road on the west. Case Inlet is located to the east of the
project site. General land use in the vicinity of the project site is single family residential
development,recreational properties, and properties managed for timber production.
Access to the site is from Grapeview Loop Road. Existing development on the project
site consists of an existing well located in the southwestern portion of the site. The
western half of the property has been filled.
Topography of the site is generally sloping downward from west to east, although much
of the site is relatively flat. There is a very slight downward slope to the east, extending
offsite to Case Inlet.
Soils on the project site are mapped in the Natural Resource Conservation Service
(MRCS) Soil Survey of Mason County Area, Washington as Sinclair shotty loam, 5-15
percent slopes. The Sinclair series is described as moderately well drained. This series is
not classified as a hydric soil by the NRCS.
Soils across the project site appear to be inconsistent with the NRCS description. While
the western half of the site is fill material, soils in the eastern portion are indicative of
seasonal saturation. Within these areas, soils are generally IOYR 2/2 or IOYR 3/1 muck
or silt loam to at least 16 inches in depth. Redoximorphic features including common
distinct 7.5YR 4/6 mottles, as well as oxidized rhizospheres were observed within 12
inches of the soil surface in mineral soils evaluated in this portion of the site.
Vegetation in the western half of the site consists of grasses and forbs that have become
established on the fill material. Species observed in the eastern portion of the site are
indicative of seasonal saturation. Species observed in this area include: red alder, cattail,
common horsetail, soft rush,Nootka rose, subarctic ladyfern,and Himalayan blackberry.
The area is essentially dominated by forbs and scattered shrubs,with the only trees on the
parcel being a cluster of red alder in the southeastern portion of the site.
Hydrology or indicators of hydrology within 12 inches of the soil surface was observed
across the eastern portion of the site. Indicators of hydrology which were observed
included: water stained leaves, and oxidized root zones and iron soft masses in the upper
portion of the soil profile. In addition, saturation within 4-6 inches of the soil surface was
observed across the eastern half of the site. Hydrology on the site appears to be the result
of seepage, sheet flow, and groundwater from offsite to the west. Drainage from this area
extends offsite to the east, draining across the tidelands into Case Inlet.
As a result of site evaluation,a single wetland area was observed onsite which would be
regulated by Mason County. The wetland dominates the eastern half of the site, but does
not extend offsite to the north or south, likely due to past filling activities associated with
existing residential development on adjacent properties. The wetland is a palustrine
emergent persistent seasonally saturated slope system,that would best be rated as a
Category III wetland by Mason County. Although it is adjacent to the shoreline of Case
. 1
Mr.Bovey

Inlet, it is not an estuarine wetland,and the water source is freshwater supplied by
groundwater seepage from the sloping areas west of the site. Category III wetlands
require an 80 foot buffer from the delineated edge of the wetland, under Mason County
Resource Ordinance, Chapter 17.01.070D (based on the proposed high intensity land
use).
As shown on the attached site plan, the required 80 foot wetland buffer would encumber
nearly the entire site with wetland or wetland buffer. To allow reasonable use of the site
(development of a single family residence), Mason County will allow reduction of the
wetland buffer to facilitate the development of a single family residence on the site. As
part of the buffer reduction,the applicant will complete enhancement of the wetland and
reduced buffer through vegetation plantings and invasive species removal.
Some Himalayan blackberry is present within the wetland area to be enhanced.
Individual blackberry plants should be completely grubbed out by hand and
removed to prevent spreading or resprouting of blackberry. Soils within the
disturbed area are mainly muck or silt loam which will prevent loss of revegetation
from drought during the summer dry season. Soils should be well suited to the
revegetation work, and do not need to be amended prior to planting.
Although the area will naturally revegetate over time, some revegetation of the area
is proposed. This will help to accelerate the revegetation of the area, and enhance
wetland and shoreline functions. Typical buffer functions include: water quality
functions, screening of the shoreline from adjacent land uses, and providing
wildlife habitat and connectivity for a variety of species.
The proposed buffer restoration plan for this project is to establish additional native
shrubs within the onsite wetland area,and establish a narrow buffer on the existing
fill material. Water quality functions will be maintained through the establishment
of native woody vegetation within the wetland area. This will increase root
structure within the wetland,providing for increased infiltration, sediment trapping,
and soil formation. Wildlife habitat within the wetland will be enhanced by the
establishment of tree and shrub vegetation.
Himalayan blackberry within the planting area is also of concern for the
establishment of low growing species. The best long term solution to suppress
blackberry is through the establishment of a shade canopy. Deciduous species have
been selected, and will provide the initial framework for coniferous species to
ultimately become established.
Plantings proposed are native species, and have been selected based on site
conditions(soils,moisture levels,and light), and will provide an initial framework
where other native species can become established within wetland area.
Mr.Bovey
March 23,2009

Very few native trees and shrubs are currently present in the planting area, and will
be left undisturbed. Plantings will be randomly spread throughout the disturbed
area to replicate natural conditions,as shown on the site plan. The proposed area
to be planted, as well as the species to be utilized, are shown on the attached
planting plan. Proposed species to be used include: red alder,Nootka rose,hard
hack, and Sitka willow. These species are all present in the vicinity of the planting
area, and are well suited to the site.
Plantings will be container plants, and will be obtained from a local source in
Western Washington. Planting will be completed during the wetter, colder months
(November through March)to assure maximum survival and viability. Due to the
relative simplicity of this project,planting and maintenance work can be completed
by the property owner of their designee. Existing blackberry,which is present in
the proposed revegetation area,will be removed by pulling prior to planting.
Invasive species will be controlled by pulling or cutting,using hand tools
(machetes, shovels)or hand held power tools (weed wackers). The focus of the
maintenance will be to assure maximum survival of plantings. Plantings should
become established, and will ultimately suppress invasive species. The main
species of concern on this site is Himalayan blackberry.
Planted species will be monitored for at least one year following planting. Survival
at the end of the first growing season should meet or exceed 80 percent. Volunteer
native, woody species which become established within the buffer can be included
in this total. If this success standard is not met,measures will be taken to meet this
goal (additional plantings,maintenance, and monitoring). Contingency actions that
may be necessary should be apparent by the end of the first growing season
following planting.
Monitoring will be completed by the property or their representative. Monitoring
will consist of at least two visits the first year to evaluate the site for plant survival,
vigor, and assure that invasive species are being controlled. Vandalism or other
damage should also be addressed. Any deficiencies should be noted and reported
to Thurston County following the first growing season.
