WETLAND DELINEATION AND ANALYSIS REPORT
,
Hudson Property
Port Townsend, Washington „AR 3 1 2009
INTRODUCTION
EnviroSound Consulting, Inc. (EnviroSound) has been authorized by Kathleen Hudson to
perform a wetland delineation at the properties located at 758 North Jacob Miller Road in Port
Townsend, Jefferson County, Washington (Tax Identification Numbers 999006203 and
999006301). The delineation was performed on April 4, 2008.
For the purposes of federal, Washington State, and Jefferson County jurisdictional oversight,
methodology used for the wetland delineation is consistent with the definition provided in
paragraph 25a of the Washington State Wetlands Identification and Delineation Manual
' (Washington State Department of Ecology [Ecology] 1997). The sections below provide: (1) an
introduction to the site; (2) a description of methods used in the field delineation; and (3)
technical results.
GENERAL SITE CONDITIONS
The subject properties are located in the SE% of Section 32, Township 31 North, and Range 01
West (Figure 1). The western parcel is L-shaped and 1.25-acres in size. The eastern property is
' rectangular in shape and 1.85 acres in size. The properties are accessed via Jacob Miller Road in
Port Townsend, Washington. The western property is comprised of a shrub scrub, mowed
pasture, and a forested community. The shrub-scrub area is dominated by Nootka rose and
elderberry. The pasture community is dominated by reed canary grass and unknown pasture
grasses. The forested community is dominated by grand fir, Douglas fir, and red alder with an
understory of sword fern and salmonberry. There is a pond with a surrounding wetland on the
southern portion of the property. The eastern property is comprised of a forested community and
the pasture community continued from the western parcel. The forested community is
dominated by red alder, grand fir, and Douglas fir with an understory of sword fern and nootka
rose. A man-made ditch flows west out of the pond toward the southeast property corner.
Although there are two separate tax parcels, one single family residence will permitted to be
built. The delineated wetland has been classified as a Category III Depressional wetland
requiring 60 feet of buffer.
The parcel slopes quickly to the south toward the onsite wetland (Figure 2). The parcel is
undeveloped and is regularly mowed. One wetland was delineated on the subject property. It is
located on the southern portion of the parcel. The wetland is comprised largely of red alder and

western red cedar with an understory of salmonberry, slough sedge, Nootka rose, and reed
canary grass. Upland areas are dominated by grand fir and Douglas fir with a typical understory
of sword fern, salal, Indian plum, and elderberry. Figure 2 illustrates the wetland boundaries.
METHODOLOGY
Review of Existing Information
Consistent with procedures detailed in the Washington State Wetlands Identification and
S
Delineation Manual (1997 Manual) (Ecology 1997), EnviroSound gathered preliminary
information on the project site prior to the field review and delineation. General information
sources included: United States Geological Survey (USGS) topographic maps, 1974 United
States Fish and Wildlife Service (USFWS)National Wetland Inventory(NWI) maps, Soil Survey
of Jefferson County Area, Washington (United States Department of Agriculture [USDA] 1977),
and Jefferson County's critical areas regulations — Jefferson County Code (JCC) Title 18.22,
Wetlands (JCC 18.22 Article VII).
Field Delineation
Methodology used for wetland delineation was consistent with the technical approaches
articulated in the 1997 Manual. 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 extent and location of project related wetlands were determined during field work. Field
work was conducted under rainy skies with an ambient temperature of approximately 45 degrees
Fahrenheit. The time of year and recent precipitation history were considered in assessing the
type and extent of wetlands and stream typing presumed to exist on and in proximity to the site.
Wetlands identified during field work are considered potential wetlands until their presence is
confirmed through Jefferson County or U.S. Army Corps of Engineers review.
Specific field methodology used in determining the extent and location of wetland areas include:
1. As part of the initial project site reconnaissance, the site was walked to determine the
general extent and location of potential wetland areas;
2. Wetland and upland sample plots were established in the identified potential wetland
areas and in the adjacent upland area; and
3. Wetland boundaries were delineated with flagging by noting localized topography and
vegetation patterns and comparing parameters of hydrology, soil, and vegetation with
data collected at the wetland and upland sample plots.
Specific field methodologies for plot sampling; hydrology, soil, and vegetation evaluation; and
boundary delineation are described in Appendix A. Data collected at each sample plot were
entered onto a Routine Wetland Determination Data Form (Ecology 1997). Copies of data forms
for each sample plot are provided in Appendix B.

' WETLAND EVALUATION JEFEERSLItil NUNN Jcc
Wetlands were classified and rated using the categories set forth in JCC 18.22 Article VII, which
defines wetland categories according to Washington State Wetland Rating System, Western
Washington, 2nd Edition, " or as amended hereafter (Ecology 1993). This wetland evaluation
' used the new rating manual, Washington State Wetland Rating System for Western Washington
(Hruby 2004). This system identifies various complexities within wetland structures, habitat
attributes and various functions associated with wetlands. The rating forms completed for this
wetland are provided in Appendix C.
BACKGROUND INFORMATION
Watershed
The parcel is located within the Tibbals Lake watershed, approximately 0.50 miles south of the
Strait of Juan de Fuca and 2.50 miles west of Admiralty Inlet of Puget Sound. An unnamed
creek is located approximately one mile east of the subject property which flows into the Strait of
Juan de Fuca. The creek is a Type F (F=fish-bearing) stream (Figure 3).
Jefferson County Soil Survey
The soil survey of Jefferson County indicates one onsite soil type which has been identified as:
CmC-Clallam gravelly sandy loam, 0 to 15 percent slopes. This nearly level to rolling soil is
on terraces. Most slopes range from 5 to 10 percent. This soil is well drained. Permeability is
moderate above the cemented layer. Roots penetrate to a depth of 20 to 40 inches. This soil
' holds about 2 to 4 inches of water available for plants. Runoff is slow to medium, and the hazard
of water erosion is slight to moderate. The soil is saturated part of the time during the rainy
season, and at times water moves laterally, in places, above the cemented layer. Capability unit
IVe-1; woodland group 4d2.
A more detailed description of this soil is presented in Appendix D. Soil location is illustrated in
Figure 4 -Jefferson Soil Survey map.
National Wetlands Inventory
The wetland delineated by EnviroSound on this site is listed on the USFWS NWI map as
Palustrine/ Scrub Shrub/ Seasonally Flooded (PSSC). There are three freshwater wetlands listed
within a half mile of the subject property. The largest is situated to the south and is listed as
Palustrine/ Emergent/ Scrub-Shrub/ Seasonally Flooded (PEM/SSC), Palustrine/ Emergent/
Semi-permanently Flooded (PEMF). To the south of this another wetland is listed as Palustrine/
Scrub Shrub/ Temporarily Flooded (PSSA). The third wetland is further to the south and listed
as Palustrine/Aquatic Bed/Permanently Flooded(PABH) (Figure 5).
Priority Species Listing and National Heritage Features
The Washington Department of Fish and Wildlife — Habitats and Species map for Jefferson
County indicates that no priority species exist onsite. No State Candidate Species, Threatened,
Priority or Other Priority Habitats are located within one-half mile of the subject parcel. The

EnviroSound delineated one wetland on the subject property. The wetlandJ N 'lb'cated 'PP tkd
southern portion of the parcel. The northern boundary of the wetland was delineated. The
wetland is comprised partially of a forested community dominated by red alder, western red
cedar with an understory of salmonberry, slough sedge, and Nootka rose. Another portion of the
wetland is dominated by a pasture community dominated by reed canary grass. The onsite
wetland surrounds a man-made pond and ditch which flows to the east into the pond. The
delineated wetland is located in a depression at the bottom of the slope (Figure 2).
Soils
Soil analysis within the wetland consisted of two sample pits (Figure 2). The first sample pit,
SP-2, revealed the soil to seven inches below ground surface to be a sandy loam. It exhibited a
matrix chroma of 10YR 2/2 (Munsell reading) with no mottles. The soil from seven to sixteen
inches below ground surface was observed to be clay. It exhibited a low matrix chroma of 10YR
4/2 (Munsell reading) with common, course, and distinct mottles of 10YR 4/4 (Munsell reading).
Wetland soil characterization is not consistent with that described as Clallam gravelly sandy
loam, 0 to 15 percent slopes in the Soil Survey of Jefferson County Area(USDA 1977).
The second sample pit, SP-4, revealed the soil to two inches below ground surface to be a loam.
It exhibited a matrix chroma of 10YR 3/2 (Munsell reading) with no mottles. The soil from two
to sixteen inches below ground surface was observed to be loam. It exhibited a low matrix
chroma of 10YR 4/2 (Munsell reading) with few, small, and distinct mottles of 10YR 4/4
(Munsell reading). Wetland soil characterization is not consistent with that described as Clallam
gravelly sandy loam, 0 to 15 percent slopes in the Soil Survey of Jefferson County Area (USDA
1977).
There were two corresponding upland sample pits. The first sample pit (SP-1) was located north
of SP-2 (Figure 2). The soil to sixteen inches below ground surface was observed to be a sandy
loam. It exhibited a matrix chroma of 10YR 2/2 (Munsell reading) with no mottles. Upland soil
characterization is not consistent with that described as Clallam gravelly sandy loam, 0 to 15
percent slopes in the Soil Survey of Jefferson County Area(USDA 1977).
The second upland sample pit (SP-3) was located north of SP-4. The soil to sixteen inches below
ground surface was observed to be a loam. It exhibited a matrix chroma of 10YR 3/2 (Munsell
reading) with no mottles. Upland soil characterization is not consistent with that described as
Clallam gravelly sandy loam, 0 to 15 percent slopes in the Soil Survey of Jefferson County Area
(USDA 1977).

Hydrology u�t U;,L
Sample pit SP-2 revealed the soil to be saturated at seven inches below the surface. There was
no free water in the pit. Sample pit SP-4 revealed the soil to be saturated to the surface. The
free water was five inches below ground surface. Additionally, the FAC Neutral test passed at
SP-2 (1:0) and at SP-4 (3:0).
Soils in the upland sample pits (SP-1 and SP-3) did not exhibit characteristics of wetland
hydrology. There was no free water in the pit, no inundation, and the soil was not saturated.
Vegetation
The wetland area surrounding the test pit SP-2 had vegetation consisting of reed canary grass
(Phalaris arundinacea, FACW), and black cottonwood (Populus balsmifera, FAC). Within the
wetland, more than 50 percent of the dominant species were identified as facultative (FAC) or
wetter; and therefore meet the wetland criteria for hydrophytic vegetation(Appendix B).
The wetland area surrounding test pit SP-4 had vegetation consisting of reed canary grass
(Phalaris arundinacea, FACW), slough sedge (Carex obnupta, OBL), Nootka rose (Rosa
nutkana, FAC), red alder(Alnus rubra, FAC), western red cedar(Thuja plicata, FAC), and Sitka
willow (Salix sitchensis, FACW). Within the wetland, more than 50 percent of the dominant
species were identified as facultative (FAC) or wetter; and therefore meet the wetland criteria for
hydrophytic vegetation(Appendix B).
The upland vegetation surrounding SP-1 was not distinct from the wetland vegetation
surrounding SP-2. The upland area surrounding the sample pit SP-1 had vegetation which
included, reed canary grass (Phalaris arundinacea, FACW), and black cottonwood (Populus
balsamifera, FAC). More than 50 percent of the dominant species in this area were identified as
facultative (FAC) or wetter, and therefore meet the criteria for hydrophytic vegetation(Appendix
B).
The upland vegetation surrounding SP-3 was distinct from the wetland vegetation surrounding
SP-4. The upland area surrounding the sample pit SP-3 had vegetation which included, salal
(Gaultheria shallon, FACU+), grand fir (Abies grandis, FACU-), red alder (Alnus rubra, FAC),
reed canary grass (Phalaris arundinacea, FACW), Indian plum (Oemleria cerasiformis, FACU),
and elderberry (Sambucus racemosa, FACU). Less than 50 percent of the dominant species in
this area were identified as facultative (FAC) or wetter, and therefore do not meet the criteria for
hydrophytic vegetation(Appendix B).
WETLAND EVALUATION RESULTS
Wetland Categorization
The wetland was classified as a Depressional wetland per Washington State Wetland Rating
System for Western Washington (Hruby 2004). Based on functional attributes associated with
the wetland including habitat, water quality, and hydrology functions, it has been rated as a
Category III wetland, scoring 31 points on the state rating form. The score for water quality
functions in this wetland was 6, hydrological functions scored 6, and the score for habitat

functions was 19 (see Appendix C for rating form). This Category III wetland is regulated per
JCC 18.22. According to JCC 18.22.330, the standard base buffer width for Class III wetlands is
60 feet.
SUMMARY
This wetland report documents the presence of a Depressional wetland at parcel #999006203 and
parcel #999006301 located at 758 Jacob Miller Road in Port Townsend, Jefferson County,
Washington. The property is owned by Kathleen Hudson. The wetlands meet Jefferson
County's wetland classification criteria for a Class III wetland. According to JCC 18.22 Article
VII, the base buffer width for Class III delineated wetlands is 60 feet.
CONFIRMATION
Wetland status depicted in this report has not been confirmed by a government official,
and therefore has no legal status. Agencies with jurisdictional authority over wetlands at
the local, state and federal level need to be consulted for their signed agreement to our
findings before there is any guarantee of no change. Our estimation for the accuracy of the
unconfirmed wetland boundaries portrayed within this report is > 95%.

Plot Sampling
A pair of corresponding sample plots was established to determine the wetland area.
The locations of these sample plots are indicated in Figure 2. These sampling
locations were used as sites for the collection of hydrologic, soil, and vegetative data
in accordance with the methodologies set forth in the 1997 Manual. Data collected at
Ieach sample plot were entered onto a Routine Wetland Determination Data Form
(Washington State Department of Ecology 1997). Copies of data forms for each
sample plot are appended to this delineation report.
Hydrology Evaluation
According to the 1997 Manual, wetland hydrology is present in areas that are
inundated and/or saturated to the surface for a consecutive number of days greater
than 12.5 percent of the growing season (approximately 2 weeks in Western
Washington). Saturation to the surface is assumed when the water table—the level at
which standing water is found in an unlined hole — is found within 12 inches of the
surface in a non-sandy soil or within 6 inches of the soil surface in sandy soils.
A small soil test pit was excavated to a depth of 18 to 20 inches at the center of each
sample plot. The extent of soil inundation and saturation as well as the depth to free
water in the test pit were recorded on the Routine Wetland Determination Data Forms
as an indication of potential wetland hydrology. Other recorded potential field
indicators of wetland hydrology, as listed in the 1997 Manual, include oxidized
channels (rhizospheres) associated with living roots, water marks on vegetation or
fixed objects, drift lines, sediment deposition on vegetation and other objects, water-
stained leaves, wetland drainage patterns, and hydric soil characteristics.
Soil Evaluation
The presence of hydric soils was determined consistent with the 1997 Manual.
Fulfillment of the technical criteria for soil can be inferred by using a combination of
' published soils information and field indicators. A soil profile to a depth of 16 inches
was extracted from each sample plot test pit and the depth and character of each
distinct soil horizon was recorded. A Munsell soil color chart (Munsell Color, 2000
rev.) was used to characterize the soil. In accordance with the 1997 Manual field
protocol, soil color, hue, and chroma was recorded for each soil profile immediately
below the "A" horizon or at a depth of 10 inches, whichever is shallower. All
information collected on field soil profiles was recorded on the Routine Wetland
Determination Data Form for each sample plot.

Vegetation Evaluation
rAt each sample plot, vegetation was characterized by determining the percent aerial
cover of each plant species occurring within the herb, shrub, and tree stratum.
Dominant species in each of the three strata (tree, sapling/shrub, and herb) were
identified and recorded on the Routine Wetland Determination Data Form for each
sample plot. The wetland indicator status of the dominant species within each
' vegetation stratum was used to determine the presence of hydrophytic wetland
vegetation. Each species' indicator status was defined according to Reed (1993).
According to the 1997 Manual an area meets the hydrophytic vegetation criteria
when, under normal circumstances, more than 50 percent of the dominant species
from each stratum are obligate wetland (OBL), facultative wetland (FACW), and/or
facultative (FAC) species.
Boundary Delineation •
After characteristics of hydrology, soil, and vegetation were compared between the
confirmed upland and wetland sample plots, a boundary determination was made in
the field. The wetland boundary was determined by first noting likely areas of
topographic and vegetative distinction between wetlands and uplands, and then using
soil borings to determine the boundary between hydric and non-hydric soils. The
wetland boundary was marked with flagging spaced at a distance of approximately 20
feet.

Does the wetland being rated meet any of the criteria below? If you answer YES to any of the questions below you will
need to .rotect the wetland according to the regulations re:arding the s.ecial characteristics found in the wetland.
.,,, '0= III ' 'r !' .tsol'.As_ a .'m.iia . •1 s Yae !.
SP1. Has the wetland unit been documented as a habitat for any Federally listed Threatened or X
Endangered animal or plant species (T/E species)?
For the purposes of this rating system, "documented" means the wetland is on the appropriate
state or federal database.
SP2. Has the wetland unit been documented as habitat for any State listed Threatened or X
Endangered animal species? For the purposes of this rating system, "documented" means the
wetland is on the appropriate state database. Note: Wetlands with State listed plant species
are categorized as Category 1 Natural Heritage Wetlands (see p. 19 of data form).
SP3. Does the wetland unit contain individuals of Priority species listed by the WDFW for the state? X
SP4. Does the wetland unit have a local significance in addition to its functions? For example,the X
wetland has been identified in the Shoreline Master Program, the Critical Areas Ordinance, or
in a local management plan as having special significance.
To complete the next part of the data sheet you will need to determine the Hydrogeomorphic Class of the wetland being rated.
The hydrogeomorphic classification groups wetlands in to those that function in similar ways. This simplifies the questions needed to answer how well the wetland
functions. The Hydrogeomorphic Class ofa wetland can be determined using the key below. Seep.24 for more detailed instructions on classifying wetlands.
Wetland Rating Form—western Washington,version 2(7/06) Page 1 of 12
Wetland name or number
Classification of Vegetated Wetlands for Western Washington
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,8. .,,
1. Are the water levels in the entire unit usually controlled by tides (i.e. except during floods)?
NO—go to 2 YES—the wetland class is Tidal Fringe
If yes, is the salinity of the water during periods of annual low flow below 0.5 ppt(parts per thousand)?
YES—Freshwater Tidal Fringe NO—Saltwater Tidal Fringe(Estuarine)
Ifyour wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it is a Saltwater Tidal FringE
is rated as an Estuarine wetland. Wetlands that were call estuarine in the first and second editions of the rating system are called S;
Water Tidal Fringe in the Hydrogeomorphic Classification. Estuarine wetlands were categorized separately in the earlier editions,a
this separation is being kept in this revision. To maintain consistency between editions,the term"Estuarine"wetland is kept. Pleas
note,however,that the characteristics that define Category I and II estuarine wetlands have changed(seep. ). -
2. The entire wetland unit is flat and precipitation is only source(>90%) of water to it. Groundwater and surface water
runoff are NOT sources of water to the unit. 1 Ii�;� ,
NO—go to 3 YES—The wetland class is Flats
If your wetland can be classified as a"Flats" wetland, use the form for Depressional wetlands. ..
3. Does the entire wetland meet both of the following criteria? 'A R 3 1 2009
The vegetated part of the wetland is on the shores of a body of permanent open water(wit out any
vegetation on the surface)where at least 20 acres(8ha) in size;
At least 30%of the open water area is deeper than 6.6(2 m)? '! " !',! '
NO—go to 4 YES—The wetland class is Lake-fringe (Lacustrine Fringe)`''1,',T�
4. Does the entire wetland 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 in
flow subsurface, as sheetflow, or in a swale without distinct banks.
The water leaves the wetland without being impounded?
NOTE: Surface water does not pond in these types of wetlands except occasionally in very small and
shallow depressions or behind hummocks (depressions are usually <3 ft diameter and less than 1 foot
NO—go to 5 YES—The wetland class is Slope
5. Does the entire wetland 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 ;
river.
The overbank flooding occurs at least once every two years.
NOTE: The riverine unit can contain depressions that are filled with water when the river is not flooding;
NO—go to 6 YES—The wetland class is Riverine
6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at some tic.:
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
7. Is the entire wetland located in a very flat area with no obvious depression and no overbank flooding. The unit does rt
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
8. Your wetland unit seems to be difficult to classify and probably contains several different HGM classes. For example,seeps at the b SO
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 DIFFERE''
AREAS IN THE UNIT(make a rough sketch to help you decide). Use the following table to identify the appropriate class to use forth
rating system if you have several HGM classes present within your wetland. NOTE: Use this table only if the class that is recommerrc::
the second column represents 10%or more of the total area of the wetland unit being rated. If the area of the class listed in column 2 is
than 10%of the unit,classify the wetland using the class that represents more than 90%of the total area.

less than 10%cover of non-native plant species. If the non-native Spartina§pp,. are only species
that cover more than 10%of the wetland,then the wetland should be given a dual rating(I/II). Cat. II
The area of Spartina would be rated a Category II while the relatively undisturbed upper marsh
with native species would be a Category 1. Do not,however, exclude the area of Spartina in
determining the size threshold of 1 acre. Dual

SC2 Natural Heritage Wetlands (see p. 87)
Natural Heritage wetlands have been identified by the Washington Natural Heritage Program/DNR as
either high quality undisturbed wetlands or wetlands that support state Threatened, Endangered,or
Sensitive plant species.
SC 2.1 Is the wetland being rated in a Section/Township/Range that contains a natural heritage wetland? (This
question is used to screen out most sites before you need to contact WNHP/DNR.)

SC3 Bogs (see p. 87)
Does the wetland (or any part of the unit)meet both the criteria for soils and vegetation in bogs? Use
the key below to identify if the wetland is a bog. If you answer yes you will still need to rate the
wetland based on its function.
1. Does the unit have organic soil horizons(i.e. layers of organic soil), either peats or mucks,that
compose 16 inches or more of the first 32 inches of soil profile? (See Appendix B for a field key to
identify organic soils)? YES=go to question 3 NO=go to question 2
2. Does the wetland have organic soils, either peats or mucks that are less than 16 inches deep over
bedrock, or an impermeable hardpan such as clay or volcanic ash, or that are floating on a lake or
pond? YES=go to question 3 NO=is not a bog for purpose of rating
3. Does the unit have more than 70%cover of mosses at ground level,AND other plants, if present,
consist of the"bog"species listed in Table 3 as a significant component of the vegetation(more
than 30%of the total shrub and herbaceous cover consists of species in Table 3)?
YES=Is a bog for purpose of rating NO=go to question 4
NOTE: If you are uncertain about the extent of mosses in the understory you may substitute that
criterion by measuring the pH of the water that seeps into a hole dug at least 16"deep. If the pH is
less than 5.0 and the"bog"plant species in Table 3 are present,the wetland is a bog. 1

Old-growth forests: (west of Cascade Crest) Stands of at least two three species forming a
multi-layered canopy with occasional small openings;with at least 8 trees/acre(20 trees/hectare)
that are at least 200 years of age OR have a diameter at breast height(dbh) of 32 inches(81 cm or
more).
NOTE: The criterion for dbh is based on measurements for upland forests. Two-hundred year old trees
in wetlands will often have a smaller dbh because their growth rates are often slower. The DFW
criterion is and"OR"so old-growth forests do not necessarily have to have trees of this diameter.
Mature forests: (west of the Cascade Crest) Stands where the largest trees are 80—200 years old
OR have an average diameters(dbh)exceeding 21 inches(53 cm); crown cover may be less than
100%; decay,decadence,numbers of snags, and quantity of large downed material is generally
