Field Wetland Determination Reconnaissance
INTRODUCTION
At the request of Mathew and Krista VanDijk,The Wetland Corps performed a wetland reconnaissance
of the above referenced property located off of Ridgetop Court in Belfair, Washington. The work has
been requested in conjunction with single family development of the ownership. The property occupies
approximately five acres as recorded by the Mason County Assessor. No portion of the site is
identified on the Mason County GIS database, as"potential wetland". The focus of this work was to
produce a field determination of any wetlands that may be present on site that would require a Wetland
Delineation Report.
METHODOLOGY
Consistent with procedures detailed in the Washington State Wetlands Identification and Delineation
Manual (Washington State Department of Ecology, 2011) (2011 Manual), preliminary information was
gathered on the project site prior to the field review and delineation. General information sources
included: The preliminary site plan prepared by arrow Septic Designs, 1974 United States Fish and
Wildlife Service (USFWS)National Wetland Inventory (NWI)maps,the Soil Survey of Mason County
Area, Washington (USDA, 1960), the Washington Department of Natural Resources Water Resource
Map,and Mason County's critical areas regulations.
Field Review
The methodology used for this review was to determine if additional work consistent with the technical
approaches articulated in the 2011 manual were necessary. This document is the wetland delineation
manual that is used in determining wetland areas when applying state and local government regulations
under the Shoreline Management Act and the Growth Management Act in Washington State.
The time of year and recent precipitation history were considered in assessing the potential presence of
wetlands presumed to exist on site.
Methodology used for this field review include:
• As part of the initial project site reconnaissance, the site was walked to determine the general
extent and location of potential areas with the most probability of supporting wetlands;
• Areas of investigation were by based on topography and vegetation patterns observed throughout
the site.

GENERAL SITE CONDITIONS
The property is accessed off of NE Ridgetop CT. The parcel is bordered to the north, east, and west by
other residential parcels of similar size and shape.
The ownership generally consists of two vegetative communities. A forested upland vegetative
community occupies the property,and is comprised of a mature overstory consisting of Douglas fir and
western red cedar with an understory dominated by swordfern, salal,and evergreen huckleberry. There
is a remnant logging road grade dominated by Baltic rush(Juncus Balticus). Although Baltic rush is
documented as facultative wetland vegetation, neither soil nor hydrological indicators are present that
warrant further review of this area. The Baltic rush community is present due to anaerobic conditions
associated with soil compaction from use of the road grade. The property has been recently logged
under a DNR forest practice permit. A portion of the property has been cleared and graded. There are
no indications of critical or environmentally sensitive areas being altercated.
WETLAND DETERMINATION SUMMARY
Our findings in the field conclude that there are no wetlands on site and that there is no need for a
comprehensive wetland delineation report. The site plan prepared by Arrow Septic Designs shows all
proposed development of the property to be a sufficient distance within the property boundaries to
avoid any potential wetland buffers that could be associated with adjacent properties.
We trust this information is sufficient for your needs at this time. Thank you for choosing The Wetland
Corps as your environmental consultant. If you have any questions,feel free to call. (509) 899-0355
