Task 2.4 - Phase 1&2 Submission
Task 2.3
Shoreline Inventory and Characterization Report
Pursuant to RCW 90.58, (Shoreline Management Act of 1971), the City of Millwood, Washington is updating its Shoreline
Master Plan (SMP), which is part of the larger Shoreline Master Program governing the watersheds included in Spokane
County.
Pursuant to RCW 36.70A.172, (Growth Management Act), planning that was completed earlier for local Critical Areas
such as shorelines, wetlands, areas with critical recharging effect on aquifers, and fish and wildlife habitat conservation,
can be found in the City of Millwood Comprehensive Plan, Appendix B, Shoreline Master Program. The updated SMP will
replace portions of that Appendix.
In this section of the 2011 Draft SMP, shorelines, lands extending two-hundred (200) feet inland from the ordinary high
water mark of the Spokane River, wetlands, lakes and reservoirs, fish and wildlife habitat and sites with archaeological
and historic significance that are under the jurisdiction of the City of Millwood are inventoried and characterized.
A. Shorelines of the State
The northern boundary of the City of Millwood, as shown in Appendix 1 of this document, is a designated Shoreline of the
State (per RCW 90.58.030(2)). This State designation includes marine shores, shorelines of streams with a mean annual
flow greater than twenty (20) cubic feet per second (cfs), and the shorelines of lakes and other water bodies greater than
twenty (20) acres in size. The Spokane River, as it passes through Spokane County, complies as a river with a mean
annual flow greater than 20 cubic feet per second and as Shoreline of Statewide significance.
The portion of the Spokane River that flows through Spokane County was assessed and inventoried by the Spokane
County Conservation District in 2005. This inventory report separated the Spokane River into twenty-two (22) discrete
segments, called reaches. Each reach was separated and characterized because of its similar habitat and functionality.
The vast majority of the City of Millwood is located in reach seven (7) of the Spokane River. The eastern-most three
hundred (300) feet of Millwood (from a point equidistant from Davis road and Butler road and extending east to the city
limits) is in reach six (6). These river segments are different in character and are described in detail below.
Task 2.4 – Phase 1&2 Submissions
Page 1
Task 2.4 - Phase 1&2 Submission
Reach Seven:
Reach seven extends from River Mile eighty-three point four (83.4), which starts six tenths (.6) of a
mile downstream from the Centennial Trail Foot Bridge near Plantes Ferry to River Mile eighty-one point one (81.1), one
point three (1.3) miles downstream of the Argonne Road Bridge.
Reach Six: Reach six extends from River Mile eighty-six point two (86.2), starting at the railroad trestle one half (.5) mile
downstream of the Sullivan Road Bridge and River Mile (83.4), six-tenths of a mile downstream from the Centennial Trail
Foot Bridge near Plantes Ferry.
See the map Appendix 2 for reach and river mile identification.
B. Spokane River Channel Migration and Floodplain
Reach Seven:
Reach seven is backwatered from Upriver Dam with a channel that is moderately to highly
entrenched in a low sinuosity channel. There is little to no floodplain development. Due to the depth of the pool, the bed
materials are unknown. Within the Millwood city limits, single and multi-family residential housing, along with shoreline
bulkheads, dominate the streambanks along the western portion of this reach, from the Argonne Bridge west to the city
limits. The streambanks, excluding the boulders at the eastern end of the reach, are composed of unconsolidated,
heterogeneous, non-cohesive materials. Because of the dams upstream and downstream, during periods of nonsnowmelt the current is slow and the sediment supply is low. Spring runoff, depending on the snow level in the Spokane
River watershed, temporarily raises the speed and pool height of the river and temporarily increases the erosion of the
streambanks. The channel is vertically and laterally stable and is comprised of a single deep pool.
Several areas along the river, especially in the eastern half of the reach, are lined with grasses and native trees. Due to
human intervention, large woody debris which would serve as fish habitat is generally lacking. Because of the low water
velocities during much of the year, the man-made structures along the banks are adequate to dissipate energy and
protect banks from erosion during normal flow periods.
The sinuosity for reach seven is approximately one (1.0). The sinuosity appears to be controlled by the entrenched
stream channel, bedrock outcrops, large boulder deposits, and recently added, man-made, bulkheads. The gradient for
the reach is approximately 0.00042. The width/depth ratio is low due to the impoundment of this reach from Upriver Dam.
Task 2.4 – Phase 1&2 Submissions
Page 2
Task 2.4 - Phase 1&2 Submission
Reach Six: Reach six is also backwatered from Upriver Dam and the channel here is moderately to highly entrenched
with little to no floodplain development. The dominant bed materials are cobbles with boulders from glacial outwash
deposition. Boulders dominate the river edge and provide significant energy dissipation and stabilization. Outcrops of
bedrock and extremely large boulders occur in this reach.
The streambanks, excluding the boulders, are composed of unconsolidated, heterogeneous, non-cohesive materials that
are finer than the bed material. Because of the dams upstream and downstream, sediment supply is low unless the
streambanks are actively eroding. The current is generally swift and the channel is comprised of a series of rapids with
shallow pools. The channel is vertically and laterally stable.
Large woody debris is lacking, but rocks are adequate to dissipate energy and protect banks.
The sinuosity for reach six is approximately one point three (1.3). This sinuosity is controlled by the entrenched stream
channel, bedrock outcrops, and large boulder deposits. The gradient for the reach is approximately 0.00038. The
width/depth ratio is high, greater than twenty (20), in the riffles and moderate in the pools. The pools are generally
shallow and swift with width/depth ratios around twenty (20). Erosion along this reach is moderate with several stretches
of eroding banks from recreational use along the streambanks. None of these eroding areas are within the portion of
reach 6 that exists within the City limits.
C. Aquifer Discharge/Recharge
The portion of the Spokane River that borders the City of Millwood, is located within, and influenced by, the Spokane
Valley-Rathdrum Prairie (SVRP) aquifer. From the source of the Spokane River, at the southern end of Lake Coeur
d’Alene, to Latah Creek, there are no permanent tributaries providing input to the river system. There is, however,
considerable interaction with and from the aquifer.
The SVRP aquifer begins in Idaho between Spirit Lake and the south end of Lake Pend Oreille. The aquifer flows south
until it reaches the middle of the Rathdrum Prairie, where it turns west and flows through the Spokane Valley. Most of the
flow turns north near the City of Spokane, flows through the Hillyard Trough, and then discharges into the Little Spokane
River. See the aquifer map in Appendix 3 for a visual representation of the location of the SVRP Aquifer and its relation
with the City of Millwood.
Task 2.4 – Phase 1&2 Submissions
Page 3
Task 2.4 - Phase 1&2 Submission
The Spokane River is the only watercourse over the aquifer that remains on the surface for any extended distance. The
section of the Spokane River between Lake Coeur d’Alene and Flora Road, in the City of Spokane Valley and east of
Millwood, contains a set of losing reaches, discharging water from the river and into the aquifer. Between Flora Road and
the Green Street Bridge in the City of Spokane, west of Millwood, the river contains a set of gaining reaches, where the
aquifer discharges water back into the Spokane River. The City of Millwood lies within this later section of water
accumulation. Gearhart (2001) estimated that “Between the Trent Avenue and Green Street bridges, stream flow gains
range from 260 cfs in November to 450 cfs in July.” These gains affect stream flow, water temperature, and water quality.
D. Wetlands
There are no wetlands from the National Wetland Inventory mapped in the City of Millwood.
E. Lakes and Reservoirs
There are no designated lakes and reservoirs in the City of Millwood.
F: Fish and Wildlife Habitat Conservation Areas
In the City of Millwood’s Critical Areas Ordinance (MMC 18.08), the City identifies the first 50 feet inland of the Original
High Water Mark of the Spokane River as a Critical Fish and Wildlife Habitat area buffer and presents goals for the
protection of habitat within this area. These goals are:



Conserve fish and wildlife habitat areas for the management and maintenance of fish and wildlife resources as the
City recognizes the role these areas play in the local ecosystem.
Conserve fish and wildlife habitat areas for public health, safety and well-being and the aesthetic value they bring
to the community.
Ensure that priority fish and wildlife species, as identified by the Washington Department of Fish and Wildlife, and
species of local importance, do not become increasingly imperiled due to land use changes, habitat alteration, and
other human activities.
Task 2.4 – Phase 1&2 Submissions
Page 4
Task 2.4 - Phase 1&2 Submission
The Spokane River contains fisheries and spawning areas that are important for maintaining and protecting unique or
locally significant fish populations including interior redband trout, cutthroat trout, and mountain whitefish. Spawning
areas for redband trout were identified in the 2003 Avista studies at Sullivan Road and the SRCT Bridge. The gaining
reaches of the river below Sullivan Bridge are considered critically important for the survival of salmonids in the river
system.
Identification and Characterization of the local Fauna: Wildlife along the Spokane River, as observed during the
Spokane County Proper Functioning Condition study, included red-winged blackbirds, mallards, common mergansers,
dipper, Canada geese, mourning doves, gold finch, magpies, red-tailed hawks, coyote, and beaver activity. Residents
along the river have reported seeing bald eagles, osprey, pheasant, deer, moose, rabbits, beaver, mink, river otters, and
many seasonal and year-round bird populations.
The Washington State Department of Fish and Wildlife publishes a Priority Habitats and Species (PHS) list. This list is a
catalog of habitats and species considered to be priorities for conservation and management in Spokane County. Many
of these habitats and species are found in the Millwood area. Please see Table 2.1 below for this list.

The Washington State Department of Fish & Wildlife performs physical surveys of nesting areas, breeding areas and
priority habitats for both protected and non-protected species on a regular basis. In the Millwood area, at this time, there
are no designated priority habitat areas.
Identification and Characterization of the local Flora:
Plant associations along the Spokane River provide food
and cover for different species. The Spokane River generally runs from east to west from Idaho to its confluence with
Latah Creek. Because the south-facing banks receive more afternoon sun, this results in a different microclimate and
associated plant association on each side of the river. The north side of the river, where it has not been impacted by
urban development, tends to contain more dry-tolerant vegetation than the southern side. The south side of the river
retains moisture somewhat better and native vegetation is typically denser, providing better cover for wildlife and birds.
Some of the most beneficial plant associations for supporting a wide variety of shade and cover for fish and wildlife in the
Millwood area include those containing:

Water Quality:
Water quality in the Spokane River is a result of natural influences, such as the aquifer interchange,
as well as man-made influences from upstream, such as mining and logging, point source effluents, combined sewer
overflows, and stormwater discharge.
The Federal Clean Water Act (33 U.S.C. §1251 et seq.), adopted in 1972, requires that all states restore their waters to be
“fishable and swimmable.” Pursuant to this act, the State of Washington's Water Quality Assessment is a list of the water
quality status for water bodies in the state. This assessment meets the federal requirements for an integrated status report
under Sections 303(d) and 305(b) of the Clean Water Act.
The portion of the Water Quality Assessment called the 303(d) list, as described in Section 303(d) of the Federal Clean
Water Act, comprise waters in the polluted water category. This process states that waters whose beneficial uses such as
for drinking, recreation, aquatic habitat, and industrial use that are impaired by pollutants will be placed in the polluted
water category on the water quality assessment. The Spokane River is on the State of Washington Impaired Waters list
and the 303(d) list. The water bodies that appear on the 303(d) list fall short of state surface water quality standards.
For study and reporting purposes, the Spokane River is broken into Water Resource Inventory Areas, (WRIA’s). Millwood
is in WRIA 57, the middle Spokane River. The 2008 report on findings from the middle Spokane River is attached as
Appendix 6.
The primary pollutants affecting water quality in the Millwood area include:

Heavy Metals: Metals contamination comes downstream from mining activities in the upper watershed.
Sediments in much of the Spokane River are contaminated with metals from mining and milling activities in the
Task 2.4 – Phase 1&2 Submissions
Page 8
Task 2.4 - Phase 1&2 Submission
Coeur d’Alene Basin and from industrial activities along the river. Spokane sediments have high concentrations of
arsenic, cadmium, copper, lead, and zinc. Metal concentrations in the river generally increase during high spring
flows (USGS 1998) and this contamination impacts public use of the river and its shorelines.

The Washington Department of Health (WDOH) and the Spokane Regional Health District (SRHD) has issued an
advisory to reduce recreational exposure to shoreline sediments.

In May 1999, The Washington State Department of Ecology (Ecology) began the process of trying to stop further
pollution of the Spokane River. The process began with testing for metals that got into the river because of the
historical mining practices in the Coeur d’Alene Basin in Idaho, which is now a designated federal Superfund site.
Testing was followed with cleanup of beaches along the river where the metals had settled out in amounts high
enough to threaten human health. While several areas have already been cleaned up, more cleanups are planned.
Past mining practices are not the only source of polluting metals. Water that runs off tires, for example, contains the
metal zinc. When this water makes its way to the river, it also adds to the river’s contamination

PBDEs. Testing has found unusually high amounts of PBDEs (polybrominated diphenyl ethers) in the Spokane
River. PBDEs are chemical additives used in everyday household products to reduce death and injury from fires.
Studies indicate that PBDEs are building up in people’s bodies, in animals and in the environment. Identifying the
sources of the PBDE contamination is a high priority for Ecology so that measures can be taken to control them.

Dioxins and furans. Dioxins and furans are the shortened names for a group of harmful substances that are
created when other chemicals or products are made. Some of the chemicals that, when manufactured or
processed, produce dioxins and furans include herbicides and products in the pulp and paper industry. They can
also be produced when such materials as municipal waste, sludge, medical waste, and wood are burned.
Nationwide, dioxins and furans have been found in the air, soil, sediment and food.

PCB contamination. Sediment testing has found high amounts of PCBs. PCBs get into the Spokane River
through industrial discharges, wastewater treatment plants, and storm water. The largest concentrations of PCBs in
fish or sediment have been found between the state line and Upriver Dam. While we don’t know where all the
Task 2.4 – Phase 1&2 Submissions
Page 9
Task 2.4 - Phase 1&2 Submission
PCBs come from along this reach of the river, we do know that one important historic source is the Kaiser
Trentwood plant in the Spokane Valley. Before 1994, the Spokane Industrial Park was also a likely source. Since
1995, Kaiser has taken major steps to reduce PCB concentrations in its wastewater. In addition, the Inland Empire
Paper Company mill has taken steps to reduce PCB output. Ecology also oversaw the cleanup of the General
Electric site in 1999, which was contaminated with PCBs and had an impact on the aquifer near the river.

Municipal wastewater from upstream dischargers. Municipal discharges from Liberty Lake, Hayden, Post Falls,
and Coeur d’Alene add nutrients and other pollutants to the river. Kaiser Aluminum and Inland Empire Paper
Company also discharge wastewater into the Spokane River. The major impact to the river from wastewater
discharge is phosphorous and PCB loading.

Non-point source contributions including septic tank effluent and urban stormwater runoff. The Spokane
County sewering of Spokane Valley is almost complete with the Greenacres area scheduled to be completed in
2010 and 2011. Urbanization results in increased impervious cover, resulting in increased stormwater runoff and
insertion of pollutants into the river and aquifer.
G: Geologically Hazardous Areas
Geologically hazardous areas in Millwood are limited to shore-side slide hazards due to erosion and landslide. Erosion
and/or landslide hazard areas in Millwood contain at least one of the following characteristics:



Slopes of 30% or greater
Soils identified by the Natural Resource Conservation Service as having a severe potential for erosion
Areas that are unstable as a result of rapid stream or stream bank erosion
According to the National Resource Conservation Service, a department of the U.S. Department of Agriculture, the soils in
Millwood, as seen in the mapped area in Appendix 4, consist of:
 86 %, type GgA, Garrison gravelly loam on 0-5% slopes
 5%, type GgB, Garrison gravelly loam on 5-20% slopes
Task 2.4 – Phase 1&2 Submissions
Page 10
Task 2.4 - Phase 1&2 Submission
 1.1%, type GmB, Garrison very gravelly loam, on 0-8% slopes
 7.9% water
Within the shoreline area, including the 200 foot Shoreline Management Area, the only geological hazard identified is
stream bank erosion.
H. Shoreline Land Use Patterns
The Comprehensive Plan for the City of Millwood provides land use and zoning designations. This report will break down
the river bank as east of the Argonne Road Bridge and west of the bridge. Along the Spokane River, the primary land use
west of the Argonne Bridge to the western City boundary is single family and multi-family residential. The primary land
use east of the Argonne Bridge is industrial. All of the shoreline east of the bridge, to the eastern City limit, is owned by
the Inland Empire Paper Company.
West of the Argonne Road Bridge:
West of the bridge, there are thirty-six (36) residential parcels that reside wholly
or partially within the 200 foot Shoreline Management Area parallel to the southern shoreline of the Spokane River.
Twenty-seven (27) parcels touch the shoreline. Of these parcels, one (1) parcel is multi-family, with a six (6)-unit
apartment building, and twenty-six (26) parcels contain single family residential units. The 27 residential parcels on the
shoreline stretch for two thousand six hundred seventy two (2,672) feet of frontage. Three (3) of the residential parcels
along the shore are vacant; one (1) just west of the easement on the alleyway and two (2) just east of the western-most
parcel in the City. In addition, within the shoreline management area and extending to the shoreline, there are three (3)
City easements (one of 15’ width for an alleyway east of Marguerite Road, one of 20’ width at the end of Dale Road, and
one of 40’ width at the northern end of Sargent Road). Each easement acts as the terminus of north-south streets or
alleyways.
Except for the largest City easement, there is no casual public access to the river west of the Argonne Bridge. In this 40’
easement, there has traditionally been neighborhood traffic to the shoreline to launch canoes and kayaks. There is no
dock. There is evidence of erosion within this easement area as the public has made a serpentine path down the bank to
the river. This process has continued to the point where water access is unavailable today in this area. Along with the
path, native and non-native vegetation has been cut down to enhance river views. In mid 2011, the City contacted the
Spokane County Conservation District to help with planning efforts that would provide protection to the bank from further
Task 2.4 – Phase 1&2 Submissions
Page 11
Task 2.4 - Phase 1&2 Submission
erosion and provide a usable pathway to the water. Every residential parcel, except for the two contiguous vacant ones,
currently employs at least a path, bank hardening, or a dock along the shoreline. Most residential parcels employ all
three.
The square footage of the residential parcels, plus the three City easements that are within the 200 foot Management
Area from the Ordinary High Water Mark south, comprises 11.39 acres of land. Table 2.2 describes how that land is
currently being used. As can be seen, this area is completely urban, with 97.9% of the area in Medium and High Density
Housing on lots of 7,200 square feet or larger. The full data listing all of the parcels that are impacted by the Management
Area area can be seen in Appendix 5.

East of the Argonne Road Bridge:
East of the bridge, there are five (5) residential parcels, five (5) industrial
parcels, and a small portion of an abandoned Union Pacific Railroad right-of-way that are located within the 200 foot
Shoreline Management Area extending south of the OHWM. The rails have been removed from the abandoned right-ofway. Four (4) large parcels, all zoned industrial, touch the shoreline. The industrial parcels all belong to the Inland
Empire Paper Company. The residential parcels that partially enter the Shoreline Management area are zoned low
density single family. There are four thousand six hundred eighty two (4,682) feet of frontage from the Argonne Road
Bridge to the eastern City boundary.
Task 2.4 – Phase 1&2 Submissions
Page 12
Task 2.4 - Phase 1&2 Submission
East from the Argonne Road Bridge, industrial activity is heavy for approximately the first two thousand three hundred fifty
(2,350) feet of the shoreline. The remaining two thousand three hundred thirty two (2,332) feet of shoreline contains
gravel roadways parallel to the shore, and has historically been actively used by the Inland Empire Paper Company.
Since at least 1992, photographs of the city show that heavy industrial use has ceased in this area and the land has been
left fallow. In this eastern section, the banks are not hardened and they contain mature trees and grasses. The
immediate shoreline in the western industrial area also contains mostly mature flora along the bank. There is no public
access to the river east of the Argonne Bridge, to the City limits.
The square footage of the residential and industrial parcels on the east side, plus the small piece of old Union Pacific right
of way along the eastern shore that are within the 200 foot Shoreline Management Area from the OHWM south,
comprises 21.98 acres of land. Table 2.3, describes how that land is currently being used. As can be seen, this area is
predominantly industrial, comprising 97.17% of the area. The full data can be seen in Appendix 5.

I. Historic Infill Pattern along Shoreline (Previous 20 years)
Good quality photographs exist that show the City of Millwood, plus the shoreline, for the period from 1992 to today.
When comparing photographs from 1992, 2005 and 2010, a slow addition of infill is seen west of the Argonne Road
Bridge. .
Task 2.4 – Phase 1&2 Submissions
Page 13
Task 2.4 - Phase 1&2 Submission
In 1992, there were seven (7) empty lots west of the Argonne Road Bridge, comprising 124,696 square feet of open area
and 723 linear feet of shoreline. The vegetation coverage within the 50 foot Critical Area and the 200 foot Shoreline
Management Area is not considerably different from that seen in photographs taken today. East of the Argonne Road
Bridge, the Inland Empire Paper Mill was using the two westernmost parcels for industrial activity, and the two eastern
parcels, minus a gravel road parallel to the river, within the 50 foot Critical Area, were left in a fallow state. The
abandoned Union Pacific Railroad Right of Way still has steel rails at this time.
In 2005, the western end of the shoreline has filled in to what we see today. There are three (3) empty lots, comprising
33,953 square feet of open area and 185 linear feet of shoreline. The vegetation coverage within the 50 foot Critical Area
and the 200 foot Shoreline Management Area is similar to that seen today. The same can be said east of the Argonne
Road Bridge. The Paper Mill is using the westernmost two parcels for heavy industrial production and leaving the
easternmost two parcels in a fallow state. While there is still heavily used section of rails within the Inland Empire Paper
Company property, the steel rails have been removed from the abandoned Railroad Right of Way. The impervious
coverage at the mill grew between 1992 and 2005 to where it is today.
J. Transportation
The Argonne River Bridge crosses the Spokane River approximately in the middle of Millwood. This is a high traffic span
and recent (April, 2010) trip counts by the Washington State Department of Transportation indicate an average of over
twenty nine thousand, five hundred (29,500) daily crossings. Other than small sections of residential street in the western
portion of Millwood, there are no paved roadways within the 200 foot Management Area. The asphalt paths on the Inland
Empire Paper Mill grounds that pass in the 200 foot Management Area is included in the Pavement counts in Table 2.3
above. There are no active railroad tracks within the area, but there is a small section of abandoned railroad right-of-way
at the eastern edge of the city. This abandoned right-of-way is within the 200 foot Management Area, but outside the 50
foot critical shoreline area. The Centennial Trail passes on the north bank of the river. Today, there are no active
bike/pedestrian paths within the shoreline area of the City.
K. Utilities
Within each of the city easements, there is a sewer lift station. In the easternmost easement is lift station C. This lift
station is approximately one hundred sixty-seven (167) feet south of the OHWM. Also within this easement is the backup
Task 2.4 – Phase 1&2 Submissions
Page 14
Task 2.4 - Phase 1&2 Submission
power generator for the sewage system. The power panels are approximately one hundred twenty (120) feet south of the
OHWM. In the middle easement is lift station B. This lift station is approximately one hundred ten (110) feet south of the
OHWM. In the westernmost city easement is lift station A. This sewer lift station is situated approximately ninety (90) feet
south of the OHWM. In addition to these pieces of City property, piped sewage trunk line from development in
unincorporated Spokane County north of Millwood crosses the river underneath the Argonne River Bridge.
L. Cultural/Archaeological Resources
Information provided by the Washington State Department of Archaeology and Historic Preservation does not indicate any
known cultural sites within the Shoreline Management area.
