Dear Mr. Munn,
267 Hudson Street
Port Townsend WA 98368
'EFFERSOIV CoUr4-iy I)CC1
In reference to my site visit of your property (parcels 802362003, 802362004, 802362014, and
802362015) on December 15, 2017, this letter addresses the wetland reconnaissance and ratings
there completed.
On the above referenced date, a wetland reconnaissance by James Ialeggio of Marine Sureys &
Assessments found two separate wetlands located on your property. A wetland (Wetland A) to
the east of Leland Valley Road was rated a Category 2 Riverine wetland with a buffer of 11Oft
(water quality score of 8-9, habitat score of 5-7; Jefferson County Code, Table 18.22.33012)).
Another wetland (Wetland B) was found to the west of Leland Valley Road, which was rated a
Category 3 Sloped wetland, also with a buffer of 11 Oft (water quality score of >5; Jefferson
County Code, Table 18.22.330121).
Although they are certainly hydrologically connected and both feed Lake Leland to the north,
these wetlands were deemed to be separate units for the following reasons, stipulated by the
Washington Department of Ecology's 2014 Washington State Wetland Rating System for
Western Washington:
• a distinct change of slope and therefore hydrologic conditions
• the presence of Leland Valley Rd, a manmade hydrologic barrier, between the two
wetlands.
Wetland A's approximate boundary was referenced by a set of soil plots, which were bolstered
by a clear vegetation change from upland to wetland; those points are included on the attached
image. Soil plot GPS locations are as follows:
• Dry: 47.88123, -122.88029
• Wet: 47.88134,-122.88019
Wetland B's approximate boundary`was referenced by two sets of soil plots. Although it likely
exists uphill and to the west of your property, the mapped area of Wetland B begins at the pond,
and follows a drainage east and downhill; crossing under the driveway where indicated on the
attached image, and eventually flowing under Leland Valley Road and connecting with Wetland
A. Soil plot GPS locations are as follows:
• Dry: 47.88138, =122.88389
• Wet: 47.88115,-122.88416
The locations of both the assessed wetland and the property lines on the attached image are
approximate, and meant only general reference. They do not represent a delineation of those
wetlands.
Below are attached
• data sheets from the soil survey plots;
• relevant data sheets from the two wetland ratings;
• an image showing the approximate location of your existing property lines, the two
wetlands, and their associated 100ft buffers;
• an image of the Ikm surrounding the wetlands necessary to complete the ratings,
complete with land use types.
Respectfully,
James Ialeggio, PWS

HGM Classification of Wetlands in Western Washington
For questions 177, the criteria described must apply to the entire unit being rated. .
If the hydrologic criteria listed in each question do not apply to the entire unit being rated, you
probably have a unit with multiple HGM classes. In this case, identify which hydrologic criteria in
questions 1-7 apply, and go to Question B.
Are the water levels in the entire unit usually controlled by tides except during floods?
go to 2 YES - the wetland class is Tidal Fringe - go to 1.1
1.1 Is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)?
NO - Saltwater Tidal Fringe (Estuarine) YES - Freshwater Tidal Fringe
Ifyour wetland can be classified as a Freshwater Tidal Fringe use the forms for,Riverine wetlands. If it
is Saltwater Tidal Fringe it is an Estuarine wetland and is not scored. This method cannot be used to
score functions for estuarine wetlands.
The entire wetland unit is flat and precipitation is the only source (>90%) of water to it. Groundwater
and surface water runoff are NOT sources of water to the unit.
�NO go to 3 YES - The wetland class is Flats
urwetland can be classified as a Flats wetland, use theform forDepressional wetlands.
Does the entire wetland unit meet all of the following criteria?
_The vegetated part of the wetland is on the shores of a body of permanent open water (without any
plants on the surface at any time of the year) at least 20 ac (8 ha) in size;
_At least 30% of the open water area is deeper than 6.6 ft (2 m).
NO - go to 4 YES - The wetland class is Lake Fringe (Lacustrine Fringe)
4. Does the entire wetland unit meet all of the following criteria?
_The wetland is on a slope (slope can be verygradual),
_The water flows through the wetland in one direction (unidirectional) and usually comes from
seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks,
_The water leaves the wetland without being impounded.
NO -go to5
YES - The wetland class is Slope
NOTE: Surface water does not pond in these type of wetlands except occasionally in very small and
shallow depressions or behind hummocks (depressions are usually <3 ft diameter and less than 1 ft
deep).
Does the entire wetland unit meet all of the following criteria?
_The unit is in a valley, or stream channel, where it gets inundated by overbank flooding from that
stream or river,
_The overbank flooding occurs at least once every 2 years.
Wetland Rating System for Western WA: 2014 Update
Rating Form - Effective January 1, 2015
Wetland name or number
NO - go to 6 i YES The wetland class is Riverine
NOTE: The Riverine unit can contain depressions thaf�h ed with water when the river is not
flooding
6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the
surface, at sometime during the year? This means that any outlet if present is higher than the interior
of the wetland.
NO - go to 7 YES - The wetland class is Depressional
Is the entire wetland unit located in a very flat area with no obvious depression and no overbank
flooding? The unit does not pond surface water more than a few inches. The unit seems to be
maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural
outlet.
NO - go to 8 YES - The wetland class is Depressional
Your wetland unit seems to be difficult to classify and probably contains several different HGM
classes. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small
stream within a Depressional wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY
WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT
AREAS IN THE UNIT (make a rough sketch to help you decide). Use the following table to identify the
appropriate class to use for the rating system if you have several HGM classes present within the
wetland unit being scored.
NOTE: Use this table only if the class that is recommended in the second column represents 10% or
more of the total area of the wetland unit being rated. If the area of the HGM class listed in column 2
is less than 10% of the unit; classify the wetland using the class that represents more than 90% of the
total area.

rating.

HGM Classification of Wetlands in Western Washington
For questions 1-7, tate criteria described trust apply to the entire unit being rated.
If the hydrologic criteria listed in each question do not apply to the entire unit being rated, you
probably have a unit with multiple HGM classes, In this case, identify which hydrologic criteria in
questions 1-7 apply, and go to Question S.
1. Are the water levels in the entire unit usually controlled by tides except during floods?
�' go to 2 YES - the wetland class is Tidal Fringe - go to 1.1
1.1 Is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)?
NO - Saltwater Tidal Fringe (Estuarine) YES - Freshwater Tidal Fringe
Ifyour wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it
is Saltwater Tidal Fringe it is an Estuarine wetland and is notscored. This method cannot be used to
score functions for estuarine wetlands.
2. The entire wetland unit is flat and precipitation is the only source (>90%) of water to it. Groundwater
and surface water runoff are NOT sources of water to the unit.
ro to 3 YES - The wetland class is Flats
'r wetland can be classified as a Flats wetland, use the form for Depressional wetlands.
3. Does the entire wetland unit meet all of the following criteria?
_The vegetated part of the wetland is on the shores of a body of permanent open water (without any
plants on the surface at anytime of the year) at least 20 ac (8 ha) in size;
least 30% of the open water area is deeper than 6.6 ft (2 m).
eNr
_ go to 4 YES - The wetland class is Lake Fringe (Lacustrine Fringe)
4. Does the entire wetland unit meet all of the following criteria?
_The wetland is on a slope (slope can be very gradual),
The water flows through the wetland in one direction (unidirectional) and usually comes from
seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks,
The water leaves the wetland without being impoun
NO - go to 5 S.11i he wetland class is Slope
NOTE: Surface water does not pond in these type of wetlands except occasionally in very small and
shallow depressions or behind hummocks (depressions are usually <3 ft diameter and less than 1 ft
deep).
5. Does the entire wetland unit meet all of the following criteria?
_The unit is in a valley, or stream channel, where it gets inundated by overbank flooding from that
stream or river,
_The overbank flooding occurs at least once every 2 years.

Wetland name or number
NO -go to 6 YES - The wetland class is Riverine
NOTE: The Riverine unit can contain depressions that are filled with water when the river is not
flooding
6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the
surface, at sometime during the year? This means that any outlet if present is higher than the interior
of the wetland.
NO - go to 7 YES - The wetland class is Depressional
Is the entire wetland unit located in a very flat area with no obvious depression and no overbank
flooding? The unit does not pond surface water more than a few inches. The unit seems to be
maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural
outlet.
NO -go to 8 YES - The wetland class is Depressional
Your wetland unit seems to be difficult to classify and probably contains several different HGM
classes. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small
stream within a Depressional wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY
WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT
AREAS IN THE UNIT Cmake a rough sketch to help you decide). Use the following table toidentifythe
appropriate class to use for the rating system if you have several HGM classes present within the
wetland unit being scored.
NOTE: Use this table only if the class that is recommended in the second column represents 10% or
more of the total area of the wetland unit being rated. If the area of the HGM class listed in column 2
is less than 10% of the unit; classify the wetland using the class that represents more than 90% of the
total area.

rating.
