analysis was completed to determine which wetlands were "locally significant" under state law.
The results of the analysis are added to the summary information found in Tables 1 and 2. The
term OFWAM stands for the Oregon Freshwater Wetland Assessment Methodology which by
state mandate, is the analytical tool that is used to determine if a wetland is "significant."

sopens into a 40 foot wide riparian feature. The stream segment. is-about 2:74 feet in length. and is.
abounded to the north.-and west by industrial and residential development. Some land to the south l
:and. east is undeveloped,. but tale stream is eulverted as it passes beneath hat area.. _ ~ ~;
.S-27 is a dense thicket, dominated by Pacific Willow, Black Cottonwood, Maple species, Alder . E
;species, and Hazelnut trees. At the time the stream was assessed (July 200,9) the feature was .:"
;sufficiently-shrouded`by vegetation that the consultants noted-that they.:"could-not see the :bottom
ofthe drainage due to a~steep s ope~and Salix sp.thieket." ~ ~~
No known frsh survey. was been'condueted for S=27. It is not. shown on ODFW maps of fish- .
. ,
bearing streams:-:The distance and lack of open connection to the Glenwood Slough and the x
Willamette, River argue against this being classified as afish-bearing stream.

Description: ~
W-20 is a Palustrine Shrub-Scrub wetland. It is part of a system known as the Glenwood Slough.
It flows northwest into W-21 prior to .being culverted and flowing into the Willamette River. W-
20 is bisected by Glenwood Blvd, but is still hydrologically connected by a culvert. The Slough _
is a topographic bowl. Hydrologic sources include stormwater from adjacent impervious ~
surfaces, in addition to groundwater and upslope surface water. A portion of W-20 was
previously delineated (WD96-0375).

Existing Protections
Is the site protected by minimum development setbacks and site plan review standards described
in Section 4.3-115 of the Springfield Development Code? Yes.
W-20 is associated with the Glenwood Slough (S-25, formerly E-39). The Slough is a tributary
to a water quality limited watercourse (Willamette River) and is protected by a 50-foot setback
and a site plan review requirement.
The Glenwood Refinement Plan includes policies that give direction for environmental design
affecting S-25 (formerly E-39). The Refinement Plan states, "Signif cant wetland areas in
Glenwood shall be protected from encroachment and degradation in order to retain their
important functions and values related to fish and wildlife habitat, flood control, sediment, and
erosion coritrol, water quality control, and ground water pollution control," (Policy 1, pg. 92,
Environmental Element).
Site Specific ESEE Analysis for W-20
This section discusses ESEE impacts that are specific to this particular site. For a broader
discussion of the ESEE consequences of allowing, limiting or prohibiting conflicting uses on
wetlands, see the General ESEE Analysis found in Section 8 of this report.
Environmental Consequences
W-20 is rated as a "Moderate Quality Wetland." The wetland overlaps with a riparian resource
site, S-25. S-25 is rated as a "High Quality Resource" site with a WHA score of 46-47. The
OFWAM analysis concluded that the wetland's water quality and hydrologic control functions
are impacted or degraded. The resource provides habitat for some species, although the. fish
habitat is degraded. Fully allowing conflicting uses would.mean the loss of what little function
and habitat that W-20 does provide.
Social Consequences .
The OFWAM analysis indicates that W-20 is not aesthetically pleasing, nor is it appropriate for
educational or recreational uses. The Willamalane Park and Recreation District Comprehensive
Plan shows no anticipated park facilities or natural areas near the resource site. The site has
moderate potential for enhancement which may make it more of a community amenity.
Attachment 5-5
Exhibit C-6
Economic Consequences
The OFWAM analysis indicates that the water quality and hydrologic control functions of the
resource are already degraded. These functions could be mimicked using engineered facilities at
a significant cost. Fully protecting the resource site would mean the loss of 3.73 acres of vacant
industrial land within the combined wetland and impact area boundaries.
Energy Consequences
None of note.
Recommended Program for Protection
Limit conflicting uses and employ low impact development practices when developing within
150 feet of the wetland. W-20 is associated with the Glenwood Slough. (5-25, formerly E39).
The slough is protected by a 50-foot development setback described in SDC Section 4.3-115 and
the site plan review standards described in SDC Section 5.17-100. This 50-foot setback
protecting the slough also protects W-20. Any portion of W-20 not protected by the Glenwood
Slough 50-foot setback should be protected by a 25-foot setback under provisions of SDC
Section 4.3-117.

W-20 50-ft. Setback .03 .67 .70
Total .03 .80 .83
About .13 acres of W-20 is classified as vacant by the Lane County Assessor's Office. The
vacant acreage includes portions of 1 lot. Limiting conflicting uses would allow some
development to occur within the wetland area where the developer could show how the essential
functions of the wetland could be preserved or enhanced. A 50-foot development setback is
already required for the wetland under Section 4.3-115 of the Springfield Development Code.
No additional setback is proposed.
A 50-foot setback would affect .67 acres of vacant industrial land. The affect of the setback on
buildable land could be reduced by aligning development such that yards and other open space
are within the setback. Stormwater management facilities required for development can be
placed within the setback under SDC 4.3-115.
Employing low impact development practices within 150 feet of the wetland could reduce the
impact of nearby development on the resource. Some low impact development practices are
already incorporated into the stormwater quality protection standards found in SDC 4.3-115.
Attachment 5-6
Exhibit C-7
Reduction in the Buildable Land Inventory:
The Commercial Industrial Buildable Lands Study (GIBE) that was completed in 2009 identified
a shortage of commercial and industrial lands. The Springfield Residential Lands Study (RLS)
that was also completed in 2009 identified a small surplus of residential lands. These inventories
include some Glenwood sites and classified each as "Vacant," or "Redevelopable." These
classifications are not the same used. by the Lane County Assessor's Office. These
classifications stem from judgments made by ECONorthwest in collaboration with a steering
committee that helped frame assumptions about what is redevelopable and vacant.
Protecting W-20 and its 50-foot setback area from future development effectively reduces the.
CIBL inventory by a total of .73 acres and the RLS by a total of .44 acres, for a total of 1.17
acres.

The cumulative effect of fully protecting all commercial and industrial lands that are impacted by
riparian or wetland resources could increase the need for UGB expansion to meet land needs.
A 50-foot development setback is required under stormwater provisions of the Springfield
Development Code, and thus the 1.17 impact of protecting W-20 with the setback is not
attributed to this report.

Description:
Wetland W-21 is .47 acres and classified as a Palustrine Shrub-Scrub (PSS) wetland. The
wetland is located under and east of the Interstate 5 Bridge just south of Franklin Blvd. W-21
was delineated in 2003 (WD2003-0273) as part of the ODOT's I-5 bridge project and Willamette
River trail. The west portion was impacted by construction of the I-5 temporary detour bridge.
W-21 is bounded to the south by .railroad tracks. Glenwood Slough flows through the wetland as
do several channels used to convey stormwater. The wetland is less than one-half acre and is a
judged locally significant wetland because of its hydrologic connection to the Willamette River.
It is also connected to W22 and W23.

Existing Protections
Is the site protected by minimum development setbacks and site plan review standards described
in Section 4.3-115 of the Springfield Development Code? Yes.
W-22 is associated with the Glenwood Slough-North Channel (S-25). The channel is a tributary
to a water quality limited watercourse (Willamette River) and is protected by a 50-foot setback
and a site plan review requirement. ~ - .
The Glenwood Refinement Plan includes policies that give direction for environmental design
affecting S-25 (formerly E-39). The Refinement Plan states, "Significant wetland areas in
Glenwood shall be protected from encroachment and degradation in order to retain their
important functions and values related to fish and wildlife habitat, flood control, sediment, and
erosion control, water quality control, and ground water pollution control,." (Policy 1, pg. 92,
Environmental Element).
Site. Specific. ESEE Analysis for W-22
This section discusses ESEE impacts that are specific to this particular site. For a broader
discussion of the ESEE consequences of allowing, limiting or prohibiting conflicting uses on
wetlands, see the General ESEE Analysis found in Section 8 of this report.
Environmental Consequences
W-22 is rated as a "Moderate Quality Wetland." The wetland overlaps with a riparian resource
site, S-25. S-25 is rated as a "High Quality Resource" site with a WHA score of 46-47. ~ The
OFWAM analysis concluded that W-22's water quality and hydrologic control functions are
impacted or degraded. The resource provides habitat for some wildlife species, although the fish
habitat is degraded. Fully allowing conflicting uses would mean the loss of what little function
and habitat that W-22 provides. _
Social Consequences
The OFWAM analysis indicates that W-22 is not aesthetically pleasing, nor is it appropriate for
educational or recreational uses. The Willamalane Park and Recreation District Comprehensive
Plan shows no anticipated park facilities or natural areas near the resource site. The site has
moderate potential for enhancement which may make it more of a community amenity.
Attachment 5-15
Exhibit C-16
Economic Consequences
The OFWAM analysis indicates that the water quality and hydrologic control functions of the
resource are already degraded. These functions could be mimicked using engineered facilities at
a significant cost. Fully protecting the resource site would mean the loss of 2.84 acres of vacant
industrial land within the combined wetland and impact area boundaries.
Energy Consequences
None of note.
Recommended Program for Protection
Limit conflicting uses and employ low impact development practices when developing within
150 feet of the wetland. W-22 is associated with the Glenwood Slough-North Channel (S-25,
formerly E39). The channel is protected by a 50-foot development setback described in SDC
Section 4.3-115 and the site plan review standards described in SDC Section 5.17-100.. This 50-
foot setback protecting the channel also protects W-22.
A small portion of W-22 (about .06 acres) is not protected by the 50-ft setback provided by the
stormwater WQLW standards found in SDC Section 4.3-115. This unprotected segment of W-
22 should be covered by a 25-foot development setback and the protections afforded by SDC
Section 4.3-117. Any portion of W-22 not protected by the Glenwood Slough-North Channel
50-foot setback should be protected by a 25-foot setback.

About .56 acres of W-22 is classified as vacant by the Lane County Assessor's Office. The
vacant acreage includes portions of 3 lots.. Limiting conflicting uses would allow some
development to occur within the wetland area where the developer could show how the essential
functions of the wetland could be preserved or enhanced. A 50-foot development setback is
already required for the wetland under SDC Section 4.3-115. A small portion of W-22 (about
.05 vacant acres) is not protected by the 50-ft setback, but is protected by a 25-foot setback under
the provisions of SDC Section 4.3-117. A 25-foot setback~applied to the unprotected wetland
area affects about .09 acres of the total setback acres shown for W-22.
A 25 to 50-foot setback would affect .79 acres of vacant industrial land. The affect of the
setback on buildable land could be reduced by aligning development such that yards and other
Attachment 5-16
Exhibit C-17
open space are within the setback. Stormwater management facilities required for development
can be placed within the setback under SDC Section 4.3-115.
Employing low impact development practices within 150 feet of the wetland could reduce the
impact of nearby development on the resource. Some low impact development practices are
already incorporated into the stormwater quality protection standards found in SDC Section 4.3-
115. '
Reduction in the Buildable Land Inventory:
The Commercial Industrial Buildable Lands Study (GIBE) that was completed in 2009 identified
a shortage of commercial and industrial lands. The Springfield Residential Lands Study (RLS)
that was also completed in 2009 identified a small surplus of residential lands. These inventories
include some Glenwood sites and classified each as "Vacant," or "Redevelopable." These
classifications are not the same used by the Lane County Assessor's Office. These
classifications stem from judgments made by ECONorthwest in collaboration with a steering
committee that helped frame assumptions about what is redevelopable and vacant.
Protecting W-22 and its 25-50 foot setback area from future development effectively reduces the
CIBL inventory by a total of 2.26 acres.

The cumulative effect of fully protecting all commercial and industrial lands that are impacted by
riparian or wetland resources could increase the need for UGB expansion to meet land needs.
A 50-foot development setback is already required under stormwater provisions of the
Springfield Development Code, and thus the 2.26 acre impact of protecting W-22, including its
setback, is not attributed to this report.

Description:
Wetland W-23 is .87 acres and classified as Palustrine Emergent (PEIVI) wetland. W-23 is a
series of small PEM wetlands located within the ODOT ROW and on private property. The
wetlands were delineated in 2007 for the I-5 bridge project (WD08-0140). The wetlands are
located at the bottom of a steep slope. Hydrology from the wetlands flows into a channel that
drains to the northwest into the Willamette River. The wetlands located in the ODOT ROW are.
mowed and maintained.
By state mandate; the Oregon Freshwater Wetl-and Assessment Methodology (OFWAM) is used
to~determine if a wetland is "locally significant" under Oregon law. W-23 fails all criteria for the
significance test with the exception that portions of the wetland are within '/a mile of a water
body listed by DEQ as awater-quality limited water body, and the wetland has an impacted or
degraded water quality function.

Description:
Site S-25 (formerly E-39) consists of segments of the Glenwood Slough-North Channel and a .
section of the~Moon Mt. system near or adjacent to Interstate 5, Franklin .Boulevard, Glenwood
Boulevard and the Union Pacific Railroad tracks in the Glenwood area. S-25 is generally
surrounded by industrial uses, railroad tracks and a highway.
The western portion of 5-25 wraps around,the Glenwood solid waste transfer station. At its west
end, the slough passes under the Willamette River I-5 overpass. This western portion has been
channelized with cement sides.
The portions of 5-25 on either side of Glenwood Boulevard are more natural and contain
significant riparian vegetation including willows (Salix spp.), black cottonwood (Populus
trichocarpa), sedge (Carex spp.), rush (Juncus spp.), cattails (Typha latifolia), and reed
canarygrass (Phalaris arundinacea). Interspersion with other natural areas is limited by I-5 and .
other adjacent roads, but 5-25's proximity to the Willamette River may increase the number of
wildlife species in the area. The, Division of State Lands has determined that portions of this site
are regulated wetlands (W-20, W-21, and W-22).
No fish survey was conducted for S-25 and it is not shown on ODFW maps offish-bearing
streams. The proximity and open connectivity to the Willamette River also suggests that .fish are
present in the Slough.

Existing Protections
Is the site protected by minimum development setbacks and site plan review standards described
in Section 4.3-115 of the Springfield Development Code? Yes.
S-25 includes the Glenwood Slough, the Glenwood North Channel and a section of the Moon
Mt. system. The Glenwood Slough and the North Channel are tributaries to a water quality
limited watercourse (Willamette River) and are protected by a 50-foot setback and a site plan
review requirement. '
S-25 overlaps protected wetlands W-20, W-21, and W-22. The Glenwood Refinement Plan
includes policies that give direction for environmental design affecting S-25. The Refinement
Plan states, "Significant wetland areas in Glenwood shall be protected from encroachment and
degradation in order to retain their important functions and values related to fsh and wildlife
habitat, flood control, sediment, and erosion control, water quality control, and ground water
pollution control," (Policy 1, pg. 92, Environmental Element).
Site Specific ESEE Analysis for S-25
This section discusses ESEE impacts that are specific to this particular site. For a broader
discussion of the ESEE consequences of allowing, limiting or prohibiting conflicting uses on
wetlands, see the General ESEE Analysis found in Section 8 of this report.
Environmental Consequences
With WHA scores ranging from 22 to 61 for five individual reaches of the stream, S-25 is rated
as a high quality resource site. The Riparian Functional Assessment prepared by Pacific Habitat
Services rated S-25's various reaches as well. The mode average of the assessment scores for S-
25's Water Quality and Thermal Regulation Functions was "High."; S-25's Flood Management
and Wildlife Habitat functions average was "Medium."
Much of S-25 includes inventoried locally significant wetlands (W-20, W-21, and W-22). The
water quality and hydrologic control functions of these wetland sites are impacted or degraded.
The resource provides habitat for some wildlife species, although the fish habitat is degraded.
Fully. allowing conflicting uses would mean the loss of the riparian and wetland functions that S-
25 provides.
Attachment 5-30
Exhibit C-31
Social Consequences
5-25 is located in an area that is heavily impacted by existing industrial and residential
development. The stream is not easily accessible to the public and it is not located near a school.
The Willamalane Park and Recreation District Comprehensive Plan shows no anticipated park
facilities or natural areas near the resource site. For these reasons it is not appropriate for
educational or recreational uses.
Economic Consequences
Fully allowing conflicting uses would mean the loss of the riparian and wetland functions of the
resource. These functions could be mimicked using engineered facilities at a significant cost.
Fully protecting the resource site would mean the loss~of 7.56 acres of vacant industrial land
within the combined resource and impact area boundaries.
Energy Consequences
None of note.
Recommended Program for Protection
Limit conflicting uses and employ low impact development practices when developing within
150 feet of the watercourse. S-25 includes the Glenwood Slough, the Glenwood North Channel
and a section of the Moon Mt. system. The Slough and the North Channel are protected by a 50-
foot development setback described in .SDC Section 4.3-115 and the site plan review standards
described in SDC Section 5.17-100. This 50-foot setback protecting the slough also protects.S-
25. A 339 ft. segment of S-25 is not protected by the 50-ft setback. This unprotected segment of
S-25 should be covered by a 25-foot development setback and the protections afforded by SDC
Section 4.3-117.

*A 339-ft segment of S-25 falls outside of the 50-ft protection of the stormwater WQLW
program. This segment is protected by a 25-ft. setback.
About .67 acres of S-25 is classified as vacant by the Lane County Assessor's Office. The
vacant acreage includes portions of 5 lots. Limiting conflicting uses would allow some
development to occur within the riparian resource area where the developer could show how the
Attachment 5-31
Exhibit C-32
essential functions of the riparian corridor could be preserved or enhanced. A 50-foot
development setback is already required for the riparian area under SDC 4.3-115. No additional
setback is proposed.
A 25-to-50-foot setback would affect 3.12 acres of vacant industrial land. The affect of the
setback on buildable land could be reduced by aligning development such that yards and other
open space are within the setback. stormwater management facilities required for development
can be placed within the setback under SDC Section 4.3-115.
Employing low impact development practices within 150 feet of the riparian area could reduce
the impact of nearby development on the resource. Some low impact development practices are
already incorporated into the stormwater quality protection standards found in SDC 4.3-115.
Reduction in the Buildable Land Inventory:
The Commercial Industrial Buildable Lands Study (GIBE) that was completed in 2009 identified
a shortage of commercial and industrial lands. The Springfield Residential Lands Study (RLS)
that was also completed in 2009 identified a small surplus of residential lands. These inventories
include some Glenwood sites and classified each as "Vacant," or "Redevelopable." These
classifications are not the same used by the Lane County Assessor's Office. These
classifications stem from judgments made by ECONorthwest in collaboration with a steering
committee that helped frame assumptions about what is redevelopable and vacant.
Protecting S-25 and its 25-50 foot setback area from future development effectively reduces the
CIBL inventory by a total of 3.26 acres and the RLS by a total of 1.11 acres, for a total of 3.75
acres.

A 50-foot development setback is already required under stormwater provisions of the
Springfield Development Code, and thus 2.39 acres of the 3.75 acre impact of the setback is not
attributed to this report.

Description:
Site S-26 is a perennial stream that varies in width between 2-5 feet. It is bordered to the west by
I-5. Much of the stream and the defined impact area are located within ODOT .right-of--way
adjacent to I-5 and beneath the Willamette I-5 Bridge.
S-26 is segmented, with a 462-foot culvert dividing the northern and southern segments of the
stream. The northern segment of S-26 daylights under the Willamette I-5 Bridge before
continuing north to the Willamette River. The left & right banks are similar but the average
slope of the right bank is 10% and the impervious surface is between 10-25%. About 75% of
both banks of S-26 are affected by development.
No known fish survey was been conducted for S-26. The stream is not shown on ODFW maps
of fish-bearing streams. There is an unnamed perennial drainage that begins on the west side of
I-5 (in Eugene) and is culverted under the freeway where it converges with the culverted portion
of S-26. Oregon Department of Fish and Wildlife representative, Jeff Ziller, said this Eugene
drainage that connects to S-26 has cutthroat trout. The presence of cutthroat in the Eugene
drainage suggests that 5-26 is also fish-bearing. The proximity and connectivity to the
Willamette River also suggests that fish are present in S-26. "

Site Specific ESEE Analysis for S-26
This section discusses ESEE impacts that are specific to this particular site. For a broader
discussion of the ESEE consequences of allowing, limiting or prohibiting conflicting uses on
wetlands, see the General ESEE Analysis found in Section 8 of this report.
Environmental Consequences
Although S-26 is highly disturbed, it achieved a WHA score that ranged between 17 for the
northern segment to 57 for the southern segment. S-26 is rated overall as a high quality resource
site, despite the low score for the northern segment. The northern segment has restoration
potential. and will likely receive attention as part of a larger riparian restoration project for the
area disturbed by. construction of the new Willamette I-5 Bridges.
The Riparian Functional Assessment conducted by Pacific Habitat Services indicated that the
Water Quality, Flood Management and Wildlife Habitat functions were rated "Medium." The
Thermal Regulation function was rated "High." Fully allowing additional conflicting uses would
cause the loss of these functions.
Social Consequences
5-26 is located in an area that is heavily impacted by existing. industrial development. The
stream is not easily accessible to the public nor is it near a school. For these reasons it is not
appropriate for educational or recreational uses.. The Willamalane Park and Recreation District
Comprehensive Plan shows no anticipated park facilities or natural areas near the resource site.
Economic Consequences
Fully allowing conflicting uses would mean the loss of the water quality, flood management,
thermal regulation and wildlife habitat functions of S-26. These functions could be mimicked
using engineered facilities at a significant cost. Fully protecting the resource site would mean
the loss of 1.99 acres of vacant industrial land within the combined resource and impact area
boundaries.
The Commercial Industrial Buildable Lands Study (GIBE) that was ;completed in 2009 identified
a shortage of industrial lands. The majority of small sized commercial and industrial parcels
needed for future growth shall be met within the existing UGB on small vacant and or
redeveloped parcels. Protecting 5-26 would reduce the available vacant industrial land within
the UGB to meet these needs. The cumulative effect of fully protecting all commercial and
industrial land that are impacted by riparian or wetland resources could increase the need for
UGB expansion to meet land needs.

Energy Consequences
None of note.
Recommended Program for Protection
Limit conflicting uses and employ low impact development practices when developing within
150 feet of the watercourse. S-26 is associated with the Riverview-Augusta Channel. The
Riverview-Augusta Channel is protected by a 50-foot development setback described in SDC
Section 4.3-115 and the site plan review standards described in SDC Section 5.17-100. This 50-
foot setback protecting the channel also protects 5-26. Any portion of S-26 not protected by the
Riverview-Augusta Channel's 50-foot setback should be protected by a 2:5-foot setback under .
the standards and protections found in SDC 4.3-117..
If the setback afforded to S-26 by the existing Riverview-Augusta Channel protections.is
removed, a 25-foot setback should be applied to the stream under the standards and protections
found in SDC 4.3-117.

development setback is already required for the riparian area under SDC Section 4.3-115. No
additional setback is proposed by this study.
A 50-foot setback would affect 1.26 acres of vacant industrial land. The affect of the setback on
buildable land could be reduced by aligning development such that side yards, stormwater swales
and other required open space are within the setback. stormwater mariagement facilities
required for development can be placed within the setback under SDC Section 4.3-115. .

along the watercourse. S-27 is one of those daylighted segments which opens into a 40 foot wide
riparian feature. The stream segment is about.274 feet in length and is bounded to the north and
' west by industrial and residential development. Some land to the south and east is undeveloped,
but the stream is culverted as it passes beneath that area.
S-27 is a dense thicket, dominated by willow species. At the time the stream was assessed (July
2009) the feature was sufficiently shrouded by vegetation that the consultants noted that they
"could not see the bottom'of the drainage due to a steep slope and Salix sp. thicket."
No known fish survey was been conducted for S-27. It is not shown on ODFW maps of fish-
bearing streams. The distance and lack of open connection to the Glenwood Slough and the
Willamette River argue against this being classified as afish-bearing stream.

This section discusses ESEE impacts that are specific to this particular site. For a broader
discussion of the ESEE consequences of allowing, limiting or prohibiting conflicting uses on
wetlands, see the General ESEE Analysis-found in Section 8 of this report.
Environmental Consequences
With a WHA score of 45, S-27 is rated as a high quality resource site. The Riparian Functional
Assessment prepared by Pacific Habitat Services rated the Water Quality, Flood Management,
and Wildlife Habitat as Medium. The Thermal Regulation function was rated as High. Fully
allowing additional. conflicting uses would cause the loss of these functions.
Social Consequences
S-27 is located in an area that is heavily impacted by existing industrial development. The
stream is not easily accessible to the public nor is it near a school. For these reasons it is not
appropriate for educational or recreational uses. The Willamalane Park and Recreation District
Comprehensive Plan shows no anticipated park facilities or natural areas near the resource site.
Economic Consequences
Fully allowing conflicting uses would mean the loss of the Water Quality, Flood Management,
Thermal Regulation and Wildlife Habitat functions of S-27. These functions could be mimicked
Attachment 5-41
Exhibit C-42
using engineered facilities at a significant cost. Fully protecting the resource site would mean
the loss of 2.61 acres of vacant land within the combined resource and impact area boundaries.
It would cause the loss of about 2.09 acres of industrial land and about :52 acres of low density
residential land.
The Commercial Industrial Buildable Lands Study (GIBE) that was completed in 2009 identified
a shortage of industrial lands. The majority of small sized commercial and industrial parcels
needed for future growth shall be met within the existing UGB on small vacant and or
redeveloped parcels. Protecting S-27 would reduce the available vacant industrial land within
the UGB to meet these needs. The cumulative effect of fully protecting all commercial and
industrial land that are impacted by riparian or wetland resources could increase the need for
UGB expansion to meet land needs.
The recently completed Springfield Residential Land and Housing Needs Study (2009) did not
show the affected residential properties on its inventory of vacant residential lands that will be
needed to accommodate future residential growth.
Energy Consequences
None of note.
Recommended Program for Protection
Limit conflicting uses and employ low impact development practices when developing within
150 feet of the watercourse. Establish a 25-foot development setback from the resource and
apply the standards and protections found in SDC Section 4.3-117.
The disturbed nature of the site and lack of open connectivity to the Glenwood Slough and the
Willamette River reduces the likelihood that this is vital fish habitat. The site has other habitat
values and the existing vegetation provides a valued thermal regulation function. The 25-foot
development setback would not substantially reduce those functions and would allow some
nearby development to meet industrial and residential needs. ~

Description:
S-28 is a narrow stream that meanders through a wetland area that is vegetated by willow
thickets and Reed Canary grass. It is sandwiched between the ODOT right-of--ways for the I-5
and McVay Hwy. The system is fed by a storm culvert from under the freeway and exits
through a storm culvert under McVay Hwy. and into the Willamette River.
Observed Vegetation
Native and non-native vegetation were distributed. throughout the reach and wetland. Reed
Canary grass is starting to overtake the wetland area. There is a thick canopy with cottonwoods,
maples and willows. Lots of Oak trees and Ash were visible just outside the area with a

Existing Protections
Is the site protected by minimum development .setbacks and site plan review standards described
in SDC Sections 4.3-115 and 5.17-100? No.
The Glenwood Refinement Plan includes policies that give direction for environmental design
affecting S-28. The Refinement Plan states, "Significant wetland areas in Glenwood shall be '
Attachment 5-46
Exhibit~C-47
protected from encroachment and degradation in order to retain their important functions and
values related to fish and wildlife habitat, flood control, sediment, and erosion control, water
quality control, and ground water pollution control," (Policy 1, pg. 92, Environmental Element).
Site Specific ESEE Analysis for S-28
This section discusses ESEE impacts that are specific to this particular site. For a broader
discussion of the ESEE consequences of allowing, limiting or prohibiting conflicting uses on
wetlands, see the General ESEE Analysis found in Section 8 of this report.
Environmental Consequences
With a WHA score of 61, S-28 is rated as a high quality resource site. Much of S-28 includes
inventoried a locally significant wetland (W24). The Riparian Functional Assessment prepared
'by Pacific Habitat Services rated the Water Quality, Flood Management, and Thermal
Regulation functions as High. The Wildlife Habitat function was rated Medium.
The wetland's water quality and hydrologic control functions are impacted or degraded. The
resource provides habitat for some species, but the OFWAM analysis concludes that it does not
provide a diverse wildlife habitat.
Fully allowing additional conflicting uses would cause the loss of these riparian and wetland
functions.
Social Consequences
S-28 is isolated and not easily accessible to the public. It is not near a school. The Willamalane
Park and Recreation District Comprehensive Plan shows no anticipated park facilities or natural
areas near the resource site. For these reasons it is not appropriate for educational or recreational
uses.
Economic Consequences
Fully allowing conflicting uses would mean the loss of the water quality, flood management, and
thermal regulation and wildlife habitat functions that are provided by S-28. These functions
could be mimicked using engineered facilities at a significant cost. Fully protecting the resource
site would mean the loss of .39 acres of vacant Public Land and Open Space within the combined
resource and impact area boundaries.
The Commercial Industrial Buildable Lands Study (GIBE) that was~completed in 2009 did not
identify S-28 as providing needed commercial or industrial land. The Springfield Residential
Land and Housing Needs Study (2009) did not show the affected residential properties on its
inventory of vacant residential lands that will be needed to accommodate future residential
growth.

Attachment 5-47

Energy Consequences
None~of note.
Recommended Program for Protection
Limit conflicting uses and employ low impact development practices when developing within
150 feet of the watercourse. Establish a 25-foot development setback from the resource and
apply the standards and protections found in SDC Section 4.3-117.
The small stream width lack of open connectivity to the Willamette River reduces the likelihood
that this is vital fish habitat. The site has other habitat values and the existing vegetation
provides a valued thermal regulation function. The 25-foot development setback would not
substantially reduce those functions and would allow some future redevelopment to meet
residential needs.
Impact of Protection Measures on Vacant Acreage and Buildable Land Inventory
Impact on Vacant Acreage by Zoning District .
SITE ID LDR PLO TOTAL ACRES
S-28 0 0 0
S-28 25-ft. Setback 0 0 0
Total 0 0 0
None of the zoned acreage within the resource site or the 25-foot setback for 5-28 is classified as
vacant by the Lane County Assessor's Office.. Fully protecting the resource would restrict the
redevelopment of about .35 acres of low density residential land for additional housing on the
site.
Reduction in the Buildable Land Inventory:
The Commercial Industrial Buildable Lands Study (GIBE) that was completed in 2009 identified
a shortage of commercial and industrial lands. The Springfield Residential Lands Study (RLS)
that was also completed in 2009 identified a small surplus of residential lands. These inventories
include some Glenwood sites and classified each as "Vacant," or "Redevelopable." These
classifications are not the same used by the Lane County Assessor's Office. These
classifications stem from judgments made by ECONorthwest in collaboration with a steering
committee that helped frame assumptions about what is redevelopable and vacant.
Protecting S-28 and its 25-foot setback area from future development effectively reduces the
CIBL inventory by a total of .29 acres and the RLS by a total of .38 acres, for a total of .6'7 acres.

riparian or wetland resources could increase the need for UGB expansion to meet land needs.
