SITE DESCRIPTION
On May 8, 2023 Acre Environmental Consulting, LLC visited the approximate 0.49-acre site
located at 8500 Frederick Place in the City of Edmonds, Washington. The site is further located
as a portion of Section 07, Township 27N, Range 4E, W.M. The parcel number for this property is
00594400006200. The purpose of this site visit was to locate regulated critical areas on and
adjacent to the subject site. Surrounding land use is comprised of single-family residences to the
east and west, with the Southwest County Olympic View park located to the south of the site.
There are no wetlands or streams located on the subject site and no associated buffers extend
to property.
Access to this site is from the north via Frederick Place which is located along the northern border
of the property. From Frederick Place, this property has a north aspect. The subject site is
occupied by an existing single-family home and associated infrastructure (driveway and patio),
with the remaining area comprised residential landscaping. The City of Edmonds GIS maps depict
a western tributary of Perrinville Creek flowing north and west through Southwest County
Olympic View park then draining across the southwest corner of the subject site and north along
the eastern border of the adjacent property to the west. With the exception of the City of
Edmonds GIS maps, this stream is not depicted on any available mapping resource.

The methods used for assessing the project area for wetlands and streams are consistent with
current Federal, State, and City of Edmonds requirements. To determine the presence of
wetlands, Acre Environmental Consulting, LLC used the routine methodologies described in the
U.S. Army Corps of Engineers Wetland Delineation Manual produced in 1987 and the U.S. Army
Corps of Engineers Regional Supplement to the Corps of Engineers Wetland Delineation Manual:
Western Mountains, Valleys, and Coast Region produced in May 2010. The presence of streams
was assessed using the Washington State Department of Ecology guidance document titled
Determining the Ordinary High Water Mark for Shoreline Management Act Compliance in
Washington State (Publication No. 16-06-029), dated October 2016, as well as the U.S. Army
Corps of Engineers Wetlands Regulatory Assistance Program (WRAP): A Guide to Ordinary High
Water Mark (OHWM) Delineation for Non -Perennial Streams in the Western Mountains, Valleys,
and Coast Region of the United States produced in August 2014.
During our May 8, 2023 site investigation, Acre Environmental Consulting conducted a thorough
inspection of the subject site as well as that portion of the Southwest County Olympic View park
located approximately 300 feet in all directions from the subject site. Vegetation within the
portion of the Southwest County Olympic View park adjacent to the subject site is represented
by a canopy of western hemlock (Tsuga heterophylla, FacU), big leaf maple (Acer macrophyllum,
FacU), and western red cedar (Thuja plicata, Fac), with salmonberry (Rubus spectabilis, Fac),
osoberry (Oemleria cerasiformis, FacU), Sitka mountain ash (Sorbus scopulina, FacU), Salal
(Gaultheria shallon, FacU), and sword fern (Polystichum munitum, FacU), common in the
understory. Typical soils within the park and on the subject site have a Munsell color of very dark
grayish brown (10YR 3/3) with a texture of gravelly sandy loam from 0 to 10 inches below the
surface. From 10 to 18 inches below the surface, soils have a Munsell color of dark brown (10YR
3/3), and a texture of gravelly sandy loam. Soils were moist throughout the profile during our
May 8, 2023 site visit.

During this assessment we were unable to locate a defined channel within the park or on the
subject site. Furthermore, no channel is visible on the Lidar topography maps produced by
Snohomish County. The soil surface throughout this area is comprised of undisturbed duff and
topsoil (no sorted gravel or other evidence of the flow of water). As there is not a sufficient flow
of water to create a defined channel, it appears that the area in question does not meet the
definition of a stream as specified by ECC 23.90.010.A(1). Therefore, there is no stream on the
subject site or within the portion of Southwest County Olympic View park adjacent to this site.
However, Acre Environmental did note what appears to be stream located along the western
border of the adjacent lot to the west. This stream appears to originate on that lot and drain
north to Frederick Place where it enters the City stormwater system.
Cowardin: Riverine, Intermittent, Streambed (R4SB)
Edmonds Rating: Type Ns stream, 40' Buffer
An off -site stream appears to originate on the western border of the adjacent lot to the west. At
its nearest point, this stream is located approximately 55-feet west of the subject site. With the
exception of the City of Edmonds GIS maps, this stream is not depicted on any available mapping
resource. This intermittent stream appears to lack the necessary in channel habitat to support
fish use and access to this feature is impeded by downstream culverts and impassible grades. In
the City of Edmonds, Type Ns streams receive 40-foot protective buffers measured horizontally
in a landward direction from the delineated ordinary high water mark (OHWM).
Figure 4: Looking northwest across the southwest
corner of the site. Note the lack of a stream
channel on the subject site and the adjacent lot.
Figure 5: Looking southwest from Frederick Place
at the adjacent lot to the west. The off -site
stream is located between the lawn and gravel
and is used as a landscape feature.

ECDC 23.40.280 (BUILDING SETBACKS)
Except for geologically hazardous areas where setbacks are determined by a geotechnical report,
buildings and other structures shall be set back a distance of 15 feet from the edges of all critical
area buffers or from the edges of all critical areas, if no buffers are required. In addition to other
allowances provided by this title, the following may be allowed in the building setback area:
A. Landscaping;
B. Uncovered decks;
C. Building overhangs, if such overhangs do not extend more than 30 inches into the setback
area; and
D. Impervious ground surfaces, such as driveways and patios; provided, that such
improvements may be subject to water quality regulations as adopted in the current editions of
the International Residential Code and International Building Code, as adopted in ECDC Title 19.
CONCLUSION
There are no wetlands or streams located on the subject site and no associated buffers extend
to property. It appears that the stream mapped on the City of Edmonds GIS maps is not accurately
depicted. A tributary of Perrinville Creek is located along the western border of the adjacent lot
to the west. At its nearest point, this stream is located approximately 55-feet west of the subject
site. Due to the location of this stream in relation to the subject site, no portion of the 40-foot
stream buffer extends to the subject site. Therefore, any work conducted on the subject site will
be located outside of critical areas and associated buffers.
