Executive Summary
This wetland delineation was based on the Onsite Determination Method described in the Washington
State Wetland Identification and Delineation Manual (1997), and the U.s. Army Corps of Engineers
Wetland Delineation Manual (1987).
Based on the information derived through site reconnaissance and readily available documents, four
wetland areas were identified on southern portion the site, and one constructed ditch was identified in
the northwest portion of the site. The four onsite wetlands were historically part of a ravine swale that
has been highly altered. Although highly altered, the wetlands meet the biological criteria for wetlands.
According to the Renton Municipal Code, Section 4-3-0S0.M, the wetlands are category 3 systems
requiring 2S-foot buffers. The hydrogeomorphic classifications of the onsite wetlands are Slope for
Wetlands A, C, and D, and Depressional for Wetland B. The Cowardin classification of the four onsite
wetlands is Palustrine scrub-shrub/emergent, seasonally flooded. Molasses Creek, a Type A stream, is
located offsite greater than 300 feet to the southeast. Type A streams require a code-required buffer of
100 feet. A ditch is located along the north boundary of the site near the northwest corner. The ditch
near the northwest corner of the site was clearly constructed in the 1970s per the contours shown on the
Renton High School No.3 Site Plan, prepared by Fred Bassetti and Company/Architects. The ditch should
not be considered a jurisdictional wetland or stream because it was constructed when the original school
was constructed to convey runoff to a culvert along 128th Avenue SE. The site is located in the Cedar-
Sammamish Basin of Water Resource Inventory Area (WRIA) 8.

1.0 INTRODUCTION
AHBL, Inc. has completed wetland delineation on the Lindbergh High School parcel located at
16426 128'h Avenue SE, Renton, Washington (Appendix A, Exhibit WE-1). This report has been
prepared to define the wetland boundaries and buffers located on the site.
1.1 Scope of Services
The scope of work for this study was limited to the following tasks:
A review of documents readily available, including local wetland inventory maps, U.S. Fish
and Wildlife Service National Wetland Inventory Maps, aerial photographs, previous
wetland review completed by others, and Washington State Department of Natural
Resources (DNR) and Washington Department of Fish and Wildlife (WDFW) databases.
A visual assessment to observe existing site conditions and to identify wetlands located on
or within 300 feet of the site, and wildlife habitat and species located on and near the
subject parcels. Methods defined in the Washington State Wetland Identification and
Delineation Manual(1997) were used to determine the presence and extent of wetlands on
the site.
Review federal, state, and local regulations pertaining to wetlands and streams identified
on and near the site. The review is used to classify the identified wetlands, stream, and
wildlife habitat.
An assessment of onsite wetland functions and values.
A report documenting the process, findings, and conclusions for this project.
1.2 Site Location and Description
The proposed project site is comprised of three parcels (2B2305-9004, -9042, and -9093) totaling
approximately 37.25 acres, located at 16426 128'h Avenue SE, Renton, Washington (Section 28,
Township 23 North, Range 05 East, W.M.) (Appendix A, ExhibitWE-1). Onsite are existing school
buildings, parking areas and drive lanes, playfields, and track. Four wetlands are located in the
south central portion of the site. A ditch is located along the north boundary of the Site near the
northwest corner. The ditch near the northwest corner of the site was clearly constructed in the
1970s per the contours shown on the Renton High School No.3 Site Plan, prepared by Fred
Bassetti and Company/Architects (Appendix B). The ditch should not be conSidered a
jurisdictional wetland or stream because it was constructed when the original school was
constructed to convey runoff to a culvert along 128th Avenue SE. North and east of the site are
residential neighborhoods, south of the site is Renton Park, and west of the site is 128'h Avenue
SE (Appendix A, Exhibit WE-1).
2.0 DOCUMENT REVIEW
A review of readily available documents was conducted to characterize the site.

2.1 U.S. Fish and Wildlife Service National Wetland Inventory Map
The U.S. Fish and Wildlife Service National Wetland Inventory (NWI) Map of the Renton area
does not identify wetlands on or adjacent to the site.
2.2 Soil Survey of King County Area, Washington
The Soil Survey of King County Area, Washington, as depicted by the Web Soil ~urvey, was
reviewed to determine the general nature of soils on the subject site. The site was determined
to contain Alderwood and Everett soils (Appendix A, Exhibit WE-2).
The Alderwood series is made up of moderately well drained soils that formed under conifers in
glacial deposits. Permeability of this soil is moderately rapid in the surface layer and subsoil, and
very slow in the substratum. The Alderwood soil series is not listed as hydric (wetland) soil by
the Natural Resources Conservation Service (NRCS) (1995); however, Alderwood soils may
contain hydric soil inclusions.
Everett gravelly sandy loam series is made up of somewhat excessively drained soils that formed
in gravelly glacial outwash under conifers. Permeability of this soil is rapid. The Everett soil
series is not listed as hydriC (wetland) soil by the NRCS (1995); however, Everett soils may
contain hydric soil inclusions.
2.3 SalmonScape Stream Map
The Washington State Department of Fish and Wildlife (WDFW) SalmonScape Version 4 Map
indicates that Molasses Creek is located offslte to the southeast. Molasses Creek is listed as a
low gradient, between 1 and 2 percent, unconfined channel, fish bearing stream. There is one
documented partial fish blockage barrier near the Cedar River. SalmonScape does not list salmon
species within Molasses Creek near the site. Coho are listed in the stream channel downstream
approximately 1 mile (Appendix A, Exhibit WE-3). Coho are a federal Species of Concern and a
state Candidate species.
2.4 King County iMap
The King County iMap website shows a Category 1 wetland approximately 250 feet southeast of
the site, and Molasses Creek over 300 feet southeast of the site (Appendix A, Exhibit WE-4).
2.5 DNR and Fish and Wildlife Database Reviews
According to the Washington State DNR, Natural Heritage Information 5ystem website, updated
July 21, 2009, no rare plants or high quality ecosystems are located in the specific township
range and sections of the proposed project (Section 28, Township 23 North, Range 05 East,
W.M.).
The Priority Habitat and Species Database, dated June 10, 2010, indicates that (a) wetlands are
located on or near the southern portion of the site, (b) that Molasses Creek is located offsite to
the south, and ec) a bald eagle nest is located greater than three-quarters of a mile northeast of
the site on the Cedar River. Molasses Creek Is listed as containing Coho salmon, resident
Cutthroat trout, and Sockeye salmon.

3.0 SITE RECONNAISSANCE
On June 10 and 14, 2010, Theresa Dusek visited the property to evaluate the site and
surrounding area, and to flag onsite wetlands. The flags were surveyed by ESM. Four onsite
wetlands were identified in the south central portion of the site (Appendix C). Wetland boundary
flags were pink ribbon or pin flags with "Wetland Delineation" stamped on the flags. The flags
were marked with sequential numbers and wetland identifiers (W-1A indicates wetland boundary
flag 1 of Wetland A). The sampling pOint locations were marked with black and orange ribbon
flag tied onto vegetation and marked with a numeric identifier (DP-1 indicates Data Point 1).
The approximate location, size, and rating of the wetland were also determined. The site visit
included visual observation of the project site and, where possible, the surrounding area within
300 feet of the site for wetlands and fish and wildlife habitat areas. The site wetlands were
characterized by data gathered at four data points (Appendix C).
3.1 Topography
The topography of the project site and surrounding areas has been historically manipulated by
historic construction of the school facilities, local roads, parks, and reSidences. Overall, the site
slopes down from the east and west to the center of the property, with an elevation change of
approximately 25 feet. The eastern edge of the site slopes down to the east.
3.2 Fauna
A red legged frog (Rana aurora), eastern grey squirrels (Sciurus carolinensis), canadian geese
(Branta canadensis), mallards, marsh wrens (Cistothorus palustris), chickadees (poecile
atricapilla), nuthatch (Sitta canadensis), robin (Turdus migratorius), red shafted flicker (Colaptes
auratus), and sparrows were observed during the site visit.
3.3 Vegetation
Representative sampling pOints were established to document plant species and dominance of
vegetation on the subject property (Appendix D). The dominant vegetative species composition
on the site varied from scrub-shrub and emergent wetland, to Douglas fir and big leaf maple
forest, to mowed lawn and landscape beds. Overall dominant vegetation on the Site included
salmonberry (Rubus spectabilus), sedges (carex spp.), buttercup (Ranunculus repens), red alder
(Rubus spectabilus), Douglas fir (Pseudotsuga menziesii), western red cedar (Thuja plicata), salal
(Gaulthera shallon), snowberry (Symphoricarpos albus), sword fern (polystichum munitum),
dewberry (Rubus ursinus), blackberry (Rubus discolor), elderberry (Sambucus racemosa), and
Indian plum (Oemleria cerasiformis). Plant species listed federally or by the state as threatened
or endangered have not been observed on the site. Data forms detailing observations for
vegetation are included in Appendix D.
3.4 Soils
During the site evaluation, soil conditions (including color, texture, and relative moisture content)
were observed and recorded at sampling pOints on the project site. The indicators used to
identify hydric soils can be found in the Field Indicators of Hydric Soils of the United States. Soil
types observed on the site ranged from silt loam to gravelly sandy loam to glacial till. Data forms
detailing observations for soils are included in Appendix D.

3.5 Hydrology
Hydrologic conditions, including saturated soils and indicators of wetland hydrology, as defined
by the 1987 and 1997 manuals and supplement, were observed in the wetlands (Appendix 0).
Generally, the wetlands contained saturated soils at the surface with some areas of ponded water
up to 3 inches deep. Hydrology in the wetlands is controlled by groundwater seepage and
surface water runoff. Wetland A enters catch basins located on the north and east ends.
Wetland B overflows into Wetland C during large rainfall events. Wetland C and 0 typically
contain water from groundwater seepage, which leaves the wetlands via stormwater catch
basins. Historically, Wetlands A, B, and C were part of a shallow ravine system that has been
highly altered.
4.0 WETLAND
Based on the use of the triple-parameter approach, defined within the 1997 manual, and current
site conditions, four wetlands were identified in a highly modified historic swale/ravine.
Wetland 0 extends offsite to the southwest. Wetland boundaries are the same using the
supplement and the 1997 manual.
Vegetation species were identified and claSSified with a Wetland Indicator Status (WIS) assigned
by the U.S. Fish and Wildlife Service (1988 and 1993); soil conditions were identified using the
National Technical Committee for Hydric Soils Held Indicators of Hydric Soils in the United States;
and observations of hydrologic conditions, including inundation and soils saturation, were made
by hand, excavated with a shovel 18 to 20 inches deep at five representative data pOints on the
site. Additional hand-excavated test pits were completed to determine if there were differences
in soil or hydrologic conditions from the marked sample plots. The wetlands were identified as
such because all three wetland parameters were present under current site conditions using
methods for significantly disturbed sites. The wetlands have been classified using the
Classification of Wetlands and Deepwater Habitats of the United States (Cowardin et ai, 1979).
Detailed scientific knowledge of wetland functions is limited, so that evaluation of the functions of
indiVidual wetlands is qualitative and dependent upon professional judgment. The wetland was
evaluated for the following wetland functions and values: (1) flood and stormwater control,
(2) base flow and groundwater support, (3) water quality improvement, (4) natural biological
support, (5) overall habitat function, and (6) specific habitat functions.
4.1 Wetland A
The wetland is located south of the pool building and has a brick wall and catch basins within the
wetland. The wetland extends offsite to the south. In accordance with the Renton High School
No.3 Site Plan, prepared by Fred Bassetti and Company/Architects, a parking lot was originally
proposed to be constructed in this location. A note on the site plan indicates that the parking lot
layout was revised (Appendix B). The surveyed on site portion of the wetland is 5,440 square
feet in size. The total size of the wetland on and off of the site is estimated to be approximately
9,000 square feet in size. The onsite wetland is a Category 3 system with a hydrogeomorphic
classification of Slope. According to the Cowardin classification, the wetland is a Palustrine
emergent, seasonally flooded system.
Hydrologic conditions in the wetland are provided by groundwater seepage and local surface
water runoff. Water ponds on top of glaCial till and flows to the north and northeast where it
enters catch basins. Soils in Wetland A consist of silt loam underlain by a 1-inch layer of crushed

gravel underlain by glacial till. Soils have a distinct sulfidic odor. Dominant vegetation in the
wetland includes rushes, sedges, bentgrass and buttercups. Several landscape trees are rooted
on the edge or just outside the wetland and provide over story cover.
The wetland generally has low biologic functions due to its size, seasonal shallow water, and
single plant community. Habitat within the wetland system provides for a narrow range of
species that use the adjacent buffer. Snags and downed logs are not present. Habitat diversity
is provided by interspersion of "habitat" types between the wetland and adjacent forest and
shrub areas located offsite. The wetland has been cleared and filled in the past and has catch
basins and the brick wall in the wetland. The wetland buffer contains non-native invasive plant
species, including Himalayan blackberry, English ivy, and holly.
In general, the wetland has low to moderate hydrologic functions. The wetland is a historically
disturbed slope that provides water quality treatment, removal of sediments, and minimal fiood
water retention. The wetland contains cool water from groundwater discharge and transmits it
to the school storm system.
4.2 Wetland B
Wetland B is located across a gravel path and down slope from Wetland A. It is located in a
historic ravine that is now functioning as a swale. Large cottonwood trees were cut down within
the last season, and wood chips have been placed in the wetland. The estimated size of
Wetland B is 1,165 square feet. Wetland B is a category 3 system with a hydrogeomorphic
classification of Depressional and Slope. According to the Cowardin classification, the wetland is
a Palustrine scrub-shrub, emergent, semi-permanently flooded system.
Hydrologic conditions in the wetland are provided by groundwater seepage and local runoff. The
wetland contained gravelly sandy loam soils, with 2 to 6 inches of wood chips over the surface in
some areas. Dominant vegetation in the wetland includes cottonwood saplings sprouting from
stumps, branches, and roots; red osier dogwood; salmonberry; and soft rush. During the site
visit, the entire wetland system was saturated or inundated. During the June 10 site visit, water
ponded in the wetland was overflowing into Wetland C located to the east.
The wetland generally has low biologic functions due to its small size, seasonal hydrology, and
altered plant communities. Habitat within the wetland system provides for a moderate range of
species that use the adjacent forest, existing wetland habitat, downed logs, shrub, and emergent
habitats throughout different stages of their life cycle. The wetland provides SUitable refuge for a
suite of different fauna, including invertebrates, terrestrial birds, and terrestrial mammals.
Habitat diversity is provided by a broad range of structures, vegetation, and interspersion of
"habitat" types within the wetland and adjacent habitats. The wetland buffer is highly altered,
but contains an intact native plant community to the west.
In general, the wetland has low to moderate hydrologiC functions. The wetland is a depression
on a slope that provides water quality treatment, removal of sediments, and fiood water
retention. The wetland contains cool water from groundwater discharge and transmits it to
Wetland C via Infiltration and overland flow, and ultimately enters the school storm system.
4.3 Wetland C
Wetland C is located directly east of Wetland B on a cut/fill slope face and at the toe of the slope.
It is located in a historic ravine that has been filled. The estimated size of Wetland C is
1,399 square feet. Wetland C is a Category 3 system with a hydrogeomorphic classification of
Wetiand Delineation and Fish and Wildlife Habitat Report
Lindbergh High School
210299.70 mmmm
Slope. According to the Cowardin classification, the wetland is a Palustrine scrub-shrub,
emergent, semi-permanently flooded system.
Hydrologic conditions in the wetland are provided by groundwater seepage and local runoff. The
wetland contains silt loam underlain by gravelly sandy loam soils. Dominant vegetation in the
wetland includes salmonberry, red osier dogwood, bentgrass, giant horsetail, and soft rush.
During the site visit, the entire wetland system was saturated or inundated.
The wetland generally has low biologic functions due to its small size, saturated soil condition,
and altered plant communities. Habitat within the wetland system provides for a moderate range
of species that use the adjacent slope and existing wetland habitat throughout different stages of
their life cycle. The wetland provides limited breeding, food, and refuge for fauna. The wetland
buffer is highly altered.
In general, the wetland has low to moderate hydrologic functions. The wetland is a groundwater
seep on a slope that provides limited water quality treatment. The wetland contains cool water
from groundwater discharge and transmits it to the school storm system.
4.4 Wetland 0
Wetland D is located along a slope and in a shallow channel located south of Wetland C.
Wetland D extends offsite to the southwest. The surveyed onsite portion of the wetland is
1,768 square feet in size. The total size of the wetland on and off of the site is estimated to be
greater than 1 acre in size. Wetland D is a Category 3 system with a hydrogeomorphic
classification of Slope and Depressional. According to the Cowardin classification, the wetland is
a Palustrine scrub-shrub, emergent, seasonally flooded system.
Hydrologic conditions in the wetland are provided by groundwater seepage and local runoff. A
swale area at the toe of slope collects water and transmits it to the southwest. Soils in the onsite
wetland consist of silt loam. Dominant vegetation in the wetland includes red osier dogwood,
cottonwood, salmonberry, American brooklime, and buttercup. During the site visit, the entire
wetland system was saturated near the surface.
The wetland generally has moderate biologic functions due to its size and connection to other
plant communities in Renton Park that connect to the Molasses Creek corridor. Habitat within the
wetland system provides for a broad range of species that use the adjacent forest, existing
wetland habitat, snags and downed logs, shrub, and emergent habitats throughout different
stages of their life cycle. The wetland provides suitable feeding, breeding, and refuge for a suite
of different fauna, including invertebrates, amphibians, aquatic and terrestrial birds, and aquatic
and terrestrial mammals. Habitat diversity is provided by a broad range of structures,
vegetation, and intersperSion of "habitat" types within the wetland and adjacent habitats. Half of
the wetland buffer is well developed and contains forested habitat on the slopes. The wetland
buffer contains non-native invasive plant species, including Himalayan blackberry, English ivy,
and holly.
In general, the wetland has low to moderate hydrologic functions. The wetland is on a slope and
in a swale, and provides water quality treatment, removal of sediments, and flood water
retention. The seasonal saturated soil conditions and the proximity of the wetland allows for
groundwater discharge and recharge to occur in the local area.

5.0 WETLAND AND FISH AND WILDLIFE HABITAT REGULATIONS
Based on the information derived through site reconnaissance and readily available documents,
four wetlands are located on the southern portion the, site and one constructed ditch was
identified in the northwest portion of the site. The four onsite wetlands were historically part of a
ravine swale that has been highly altered. Although highly altered, the wetlands meet the
biological criteria for wetlands. According to the Renton Municipal, Code Section 4-3-0S0.M, the
wetlands are Category 3 systems requiring 2S-foot buffers. The wetlands are Category 3
because they do not meet the criteria for category 1 and 2 wetlands, and they are severely
disturbed wetlands that are characterized by human-related hydrologic alterations such as
ditching, channelization, and outlet modification; have soils alterations such as the presence of
fill, soil removal, and compaction of soils; and have altered vegetation. The City of Renton
Municipal code has many exemptions related to small category 3 wetlands. The
hydrogeomorphic classifications of the onsite wetlands are Slope for Wetlands A, C, and D, and
Depressional for Wetland B. The Cowardin classification of the four onsite wetlands is Palustrine
scrub-shrub/emergent, seasonally flooded.
Molasses Creek, a Type A stream, is located offsite greater than 300 feet to the southeast.
Type A streams require a code-required buffer of 100 feet. The buffer from Molasses Creek does
not extend onto the Site.
A ditch is located along the north boundary of the site near the northwest corner. The ditch was
clearly constructed in the 1970s per the contours shown on the Renton High School No.3 Site
Plan, prepared by Fred Bassetti and Company/Architects (Appendix B). The ditch should not be
considered a jurisdictional wetland or stream because it was constructed when the orig inal school
was constructed to convey runoff to a culvert along 128'h Avenue SE.
Critical habitat, as defined by Renton Municipal Code 4-3-0S0.K, are not located on or adjacent to
the site, including habitat aSSOCiated with the documented presence of species proposed or listed
by the federal government or State of Washington as endangered, threatened, candidate,
sensitive, monitored, or priority.
Federal and state agencies with jurisdiction over impacts to wetland located on and near the site
include the U.S. Army Corps of Engineers and the Washington State Department of Ecology.
6.0 CONCLUSION
Based on the 1997 manual, vegetation, soils, and hydrologic conditions necessary for areas to be
considered a wetland were found on the site. Four wetland areas and code required 2S-foot
buffers were identified on the southern portion the site. In addition, one constructed ditch was
identified in the northwest portion of the site.
7.0 CLOSURE
The findings and conclusions documented in this report have been prepared for specific
application to this site. They have been developed in a manner consistent with that level of care
and skill normally exercised by members of the environmental science profession currently
practicing under Similar conditions in the area. Our work was also performed in accordance with
the terms and conditions set forth in our proposal. The conclusions and recommendations
presented in this report are professional opinions based on an interpretation of information
We~and Delineation and Fish and Wildlife Habitat Report

currently available to us, and are made within the operation scope, budget, and schedule of this
project. No warranty, expressed or implied, is made.
Wetland boundaries identified by AHBL, Inc. are considered preliminary until the flagged wetland
boundaries are validated by a jurisdictional agency. Validation of the wetland boundaries by the
regulating agencies provides a certification, usually written, that the wetland boundaries verified
are the boundaries that will be regulated by each agency until a speCific date or until the
regulations are modified. Only the regulating agencies can provide this certification.
Because wetlands are dynamic communities affected by both natural and human activities,
changes in wetland boundaries may be expected; therefore, wetland delineations cannot remain
valid for an indefinite period of time. The U.S. Army Corps of Engineers typically recognizes the
validity of wetland delineations for a period of 5 years after completion of a wetland delineation
report. Development activities on a site 5 years after the completion of this wetland delineation
report may require revision of the wetland delineation. In addition, changes in government
codes, regulations, or laws may occur. Because of such changes, our observations and
conclusions applicable to this site may need to be revised wholly or in part.

Definitions
Obligate Wetland. Occurs almost always (estimated probability> 99 percent)
under natural conditions in wetlands.
Facultative Wetland. Usually occurs in wetlands (estimated probability 67 to
99 percent), but occasionally found in uplands.
Facultative. Equally likely to occur in wetlands or uplands (estimated
probability 34 to 66 percent).
Facultative Upland. Usually occurs in uplands (estimated probability 67 to
99 percent), but is occasionally found in wetlands (estimated probability 1 to
33 percent).
Obligate Upland. Occurs in wetlands in other regions (as defined in the
National List at Scientific Plant Names), but occurs almost always (estimated
probability > 99 percent) under natural conditions in uplands in the region
specified. Species not on the list are assumed to be UPL and have an * to define
these species on the data forms.
No Indicator. These species have not been given an indicator status. They are
assumed to be upland or the adjacent regional indicator status is provided with a
# symbol to define these species on the data form.
