1 Executive Summary
Rich Rathvon (“the Client”) requested Peninsula Environmental Group, Inc. (“the Consultant”) to conduct
a stream assessment at 660 Twana WY, Quilcene, WA 98376; Jefferson County parcel ID 701164005; S16
T27 R1W TAX 2 (“the Site”, Figure 1, Figure 2).
Jefferson County requested a stream assessment prior to development. This assessment and report
(Report) comply with Jefferson County Code (JCC) Title 18 and has been prepared using best available
science to ensure that future development does not result in unintentional impacts to critical areas and
that all known impacts are assessed.
During the Site visit on December 13th, 2022, the Consultant delineated the ordinary high water mark
(OHWM) of Stream A using onsite evaluations, and typed the stream in accordance with WAC 222-16-030
and -031. The stream is not mapped by the Washington Department of Natural Resources (WDNR) nor
Jefferson County (Figure 3, Figure 4).
Stream A is located mostly offsite to the south, with approximately 80-linear feet (LF) in the southeast
corner of the Site. The stream runs from east to west, terminating at Dabob Bay.
Jefferson County regulates streams under JCC Chapter 18.22. Article VI Fish and Wildlife Habitat
Conservation Areas (FWHCA). The Consultant surveyed a 660-LF segment of Stream A, from Twana Way
to the top of the bluff above Dabob Bay. The following characteristics for Stream A were determined:
• 18% average grade within a 28-acre contributing basin;
• Average bankfull width of 23 inches from twelve randomly located measurements (range 16 to
30 inches);
• Average wetted width of 18 inches from twelve randomly located measurements (range from 14
to 28 inches); and
• No ponds and/or impoundments occur within the surveyed segment.
Stream A then runs down the bluff, terminating in Dabob Bay. The cascade starts at 55-ft elevation and
runs to 12-ft elevation over 68-LF. This cascade is considered a natural barrier to fish passage.
The Consultant determined that Stream A is a Type Ns stream subject to a 50-ft buffer (Table
19.300.315).
Future development of the site is not expected to alter or degrade the habitat quality or function of the
protected riparian area, as long as, all development is located outside of Stream A and its associated
50-ft buffer, and stormwater is managed in accordance with JCC.

2 Background and Site Properties
2.1 Purpose of Project
1. Conduct a desktop and Site evaluation to assess hydrological and botanical conditions.
2. Delineate OHWM of onsite/offsite stream.
3. Create site plan using collected GPS data showing critical area locations.
4. Outline findings in delineation report.
2.2 Professional Assumptions & Limitations
This Report summarizes the data collected during the Consultant’s site assessment, conversations
regarding the project, and the Consultant’s professional opinions and recommendations. The results and
recommendations contained in this report represent the Consultants’ professional opinions derived from
biological forensics, information provided to the Consultants, referenced material, and the Consultants’
experience. The Consultants’ recommendations are compiled using industry standards, best available-
science, and currently accepted best management practices.
• The Consultant visited the Site on December 13th, 2022. This Report summarizes site
characteristics as they were observed on this day only.
• This Report is intended for the exclusive use of the Client and their agents, and only for specific
application to the referenced property. This Report should not be applied to any other property
for any purpose.
• Further limitations may be found in General Assumptions and Limitations.
2.3 Methodology
OHWM Delineation
"Ordinary high water mark" on all lakes, streams, and tidal water is that mark that will be found by
examining the bed and banks and ascertaining where the presence and action of waters are so common
and usual, and so long continued in all ordinary years, as to mark upon the soil a character distinct from
that of the abutting upland, in respect to vegetation as that condition exists on June 1, 1971, as it may
naturally change thereafter, or as it may change thereafter in accordance with permits issued by a local
government or the department: PROVIDED, that in any area where the ordinary high water mark cannot
be found, the ordinary high water mark adjoining salt water shall be the line of mean higher high tide and
the ordinary high water mark adjoining fresh water shall be the line of mean high water.
Buffer distances shall be measured horizontally from the OHWM of the stream. The buffer width shall be
increased to include streamside wetlands which provide overflow storage for stormwaters, feed water
back to the stream during low flows or provide shelter and food for fish. In braided channels, the OHWM
or top of bank shall be defined so as to include the entire stream feature.
• The OHWM is identified through a two-step process. The Consultant first reviewed existing
documents, including soil surveys, inventories, and aerial photographs. After this review, the
Consultant completed a thorough field investigation of the study area.
• Global Positioning System (GPS) points were taken along the OHWM of Stream A.

Stream Typing
The stream was typed in accordance with JCC Table 18.22.630(1) and WAC 222-16-030 and -031. The
WDNR Non-Forest Land Water Type Modification Form was used as the field data collection protocol.
• Since Stream A does not meet the definition of Type S, or F Waters, stream typing was determined
through field investigations and desktop review. In the field, at least ten measurements of channel
width and wetted width were taken over a representative section of at least 500-ft. Natural and
manmade fish barriers were located and assessed. The channel characteristic points were then
used to determine the gradient of the segment by plotting the stream profile using topographic
data.
• The contributing basin of the stream was delineated using WDNR 2019 lidar data, the contributing
basin delineation protocol outlined by the Natural Resources Conservation Service (NRCS), and
ArcGIS Hydrology toolset.
Desktop Review
The Consultant reviewed the following sources for the assessment and Report:
• Parcel, contour, and critical area layers were sourced from Jefferson County Code and GIS layers;
• Soils map and hydric soil list from the United States Department of Agriculture Natural Resources
Conservation Service (USDA-NRCS);
• Climate data from the NRCS National Water Climate Center;
• Washington State Department of Natural Resources (WDNR) GIS Lidar Portal;
• WDNR GIS Open Data; and
• WDNR Forest Mapping Tool;
• See References and Resources for further citing.
Consultant Maps
Field GPS points were gathered using the Juniper Geode GNS2, which achieves submeter accuracy
depending on canopy cover, cloud cover, and satellite availability. Geospatial analyses were made using
ESRI ArcGIS using projected coordinate system NAD83 2011 US Feet for Washington State (North). Critical
area site maps were produced using data gathered during the site visits, data acquired from local and
state jurisdictions, and information furnished from the Client. These maps are intended to show the
relevant critical areas in relation to approximate proposed development. They should not be assumed to
be survey accurate.

3.3.2 Stream Typing
The surveyed stream is currently untyped. The Consultant typed the stream in accordance with JCC Table
18.22.630(1) and WAC 222-16-030 and -031. The WDNR Non-Forest Land Water Type Modification Form
was used as the field data collection protocol.
• Stream A does not meet the definition of Type S Waters as described in WAC 222-16-031.
• Stream A has a defined channel that is less than 2-ft average within the bankfull width, a gradient
more than 16%, but less than 20%, and has a contributing basin less than 50-ac. These
characteristics exclude it from falling within the definition of Type F Waters.
• Stream A is seasonal which excludes it from falling within the definition of Type Np Waters.
• Stream A was typed as Type Ns, non-fish bearing seasonal stream with a gradient less than 20%.
The stream typing protocol and results used to type Stream A are in the subsequent sections.
3.3.2.1 Channel Characteristic Measurements
Twelve randomly generated point location were examined for stream channel characteristics, which
included bankfull width and wetted stream width (Figure 5, Table 4).
• A single braided channel was included below the OHWM near CC5.
• The average bankfull width was 23 inches and ranged from 16 to 30 inches.
• The average wetted width was 18 inches and ranged from 14 to 28 inches.
• No ponds and/or impoundments were observed within the surveyed segment.
• A steep cascade (66% gradient, from 12-ft to 55-ft above sea level) is located at the western extent
of the stream segment down to the shore of Dabob Bay. This cascade acts as a natural barrier to
fish passage.

3.4 Stream Regulation
Stream A is a regulated stream because it meets the criteria set forth in Washington State Administrative
Code, the USACE Clean Water Act, Washington State Department of Fish and Wildlife (WDFW),
Washington State Department of Natural Resources (DNR), and the Environmental Protection Agency
(EPA). This designation provides certain protection to fish and wildlife habitat and their buffers from
impacts caused by nearby activities. Any impacts or proposed impacts must be mitigated to ensure that
there is no net loss of habitat functions. Buffers shall remain undisturbed natural vegetation areas except
where the buffer can be enhanced to improve its functional attributes.
1) The WDNR mapped streams in the vicinity of the Site that show similar physical characteristics
are all typed as non-fish seasonal, type Ns (5) streams (Figure 3).
2) Stream A does not meet the criteria for a fish bearing stream per WAC 222-16-031, “Stream
segments having a defined channel of 2 feet or greater within the bankfull width in Western
Washington; or 3 feet or greater within the bankfull width in Eastern Washington, and having a
gradient greater than 16 percent and less than or equal to 20 percent, and having greater than 50
acres in contributing basin size in Western Washington”
3) The Consultant typed Stream A as a Type Ns, non-fish bearing seasonal stream with less than
20% gradient, and as such, is subject to a 50-ft buffer (JCC Table 18.22.630(1).
4 Conclusions
The Action Area as proposed is located outside of Stream A and the 50-ft buffer. The Consultant
determined that future development of the site is not expected to alter or degrade the habitat quality or
function of the protected FWHCA, as long as:
• all development is located outside of Stream A and its associated 50-ft buffer;
• and stormwater is managed in accordance with JCC.
