NOTICE OF TYPE I DECISION a SENSITIVE LANDS REVIEW SLR2020-00006 MILTON COURT WATER LINE ' i 120 DAYS =January 15, 2021 SECTION I. APPLICATION SUMMARY FILE NAME: Milton Court Water Line CASE NO.: Sensitive Lands Review(SLR) SLR2020-00006 PROPOSAL: The applicant proposes to install an approximately 400-foot-long,l2-inch water line through the subject properties (WCTM 2S101CC, Tax Lot 100 and WCTM 2S112BA, Tax Lot 6100). This new line will start at an existing water line in the Milton Court cul-de-sac, and will connect to an existing water line that is located next to the railroad tracks for the TriMet WES Commuter Rail. The scope of work will take place within the Fields Natural Area, and the water line will be installed by directional boring, which will avoid impacts to a nearby locally significant wetland and its 50-foot vegetated corridor. However, the work will involve minimal ground disturbances or land form alterations in an adjacent vegetated corridor, and the Federal Emergency Management Agency (FEMA) special flood hazard area. Accordingly, this application is being processed through a Type I sensitive lands review.The applicant also proposes to remove seven(7)native trees that are located in a significant tree grove and significant habitat area.

BACKGROUND INFORMATION Site Information: The subject properties (WCTM 2S101CC,Tax Lot 100 and WCTM 2S112BA,Tax Lot 6100) are located at the northern end of the Milton Court cul-de-sac,east of Hall Boulevard,and west of the railroad tracks for the TriMet WES Commuter Rail. The applicant proposes to install an approximately 400-foot-long, 12-inch water line through the subject properties. The scope of work will take place within the Fields Natural Area, and the water line will be installed by directional boring, which will avoid impacts to a nearby locally significant wetland and its 50-foot vegetated corridor. However, the work will involve minimal ground disturbances or land form alterations in an adjacent vegetated corridor, and the FEMA special flood hazard area.Accordingly,this application is being processed through a Type I sensitive lands review. The applicant also proposes to remove seven (7) native trees that are located in a significant tree grove and significant habitat area. The subject properties are located in the Parks and Recreation (PR) Zone, and the project is considered to be an underground basic utility,which is allowed in the PR Zone. SECTION IV. APPLICABLE REVIEW CRITERIA AND FINDINGS 18.510 Sensitive Lands: 18.510.020 Applicability E. Administrative sensitive lands review. 1. Administrative sensitive lands reviews within the special flood hazard area (excluding the floodway), drainageway, slopes that are 25 percent or greater, and unstable ground are processed through a Type I procedure, as provided in Section 18.710.050, for the following actions: a. The repair,reconstruction,or improvement of an existing structure or utility,the cost of which is less than 50 percent of the market value of the structure prior to the improvement or the damage requiring reconstruction. b. Actions within the special flood hazard area: i. The construction of accessory structures up to 528 square feet in size;and ii. Any landform alternation involving up to 50 cubic yards of material. c. Actions within drainageways and slopes that are 25 percent or greater, and unstable ground: SIA2020-00006 Milton Court Watcr line 2 i. Minimal ground disturbances or landform alterations involving 10 to 50 cubic yards of material; and ii. Building permits for accessory structures that are 120 to 528 square feet in size. 2. The approval authority will approve, approve with conditions, or deny a sensitive land review application using the standards and approval criteria Sections 18.510.040, 18.510.050, 18.510.070 and 18.510.080. The applicant proposes to install an approximately 400-foot-long, 12-inch water line through the subject properties. The scope of work will involve minimal ground disturbances or land form alterations involving less than 50 cubic yards of material in a vegetated corridor associated with a drainageway and in the FEMA special flood hazard area. However, the impacted vegetated corridor area does not affect the drainageway;therefore,the findings below will only evaluate the project's impacts in the special flood hazard area. This proposal requires a sensitive lands review, and is being processed through a Type I procedure. The applicable standards and approval criteria are addressed in the findings below. 18.510.030 Administrative Provisions A. Interagency coordination. The approval authority will review all applications for a sensitive lands review to determine that all necessary approvals be obtained from those federal,state, or local governmental agencies, from which prior approval is also required. As provided in CWS "Design and Construction Standards," the necessary permits for all "development" must comply include a CWS service provider letter, which specifies the conditions and requirements necessary, if any, for an applicant to comply with CWS water quality protection standards and for the agency to issue a stormwater connection permit. The applicant obtained a Service Provider Letter from CWS on August 27,2020 (CWS file 19-002417).Clean Water Services determined there are sensitive areas present both on and off the site, and that the vegetated corridor is 50 feet wide.The agency approved of the proposal, subject to conditions related to water quality protection requirements, including enhancement of the vegetated corridor. A copy of the Service Provider Letter is attached to this decision. Additionally, staff has included a condition of approval for the applicant to comply with all CWS conditions.This standard is met. 18.510.040 General Provisions for Special Flood Hazard Areas A. Review. The approval authority will review all applications to determine whether proposed building sites will minimize the potential for flood damage. B. Special flood hazard. The areas of special flood hazard identified by FEMA in a scientific and engineering report entitled "The Flood Insurance Study for Washington County, Oregon and Incorporated Areas effective October 19, 2018" with accompanying Flood Insurance Map is hereby adopted by reference and declared to be a part of this ordinance. C. Base flood elevation data.When base flood elevation data has not been provided in compliance with Subsection 18.510.040.11, the approval authority will obtain, review and reasonably utilize any base flood elevation and floodway data available from a federal, state or other source, in order to administer Subsections 18.510.040.M and N. D. Test of reasonableness.Where elevation data is not available either through the flood insurance study or from another authoritative source,applications for building permits will be reviewed to assure that the potential for flood damage to the proposed construction will be minimized.The test of reasonableness is a local judgment and includes use of historical data,high water marks, photographs of past flooding,etc.,where available. Failure to elevate at least 2 feet above grade in these sensitive land areas may result in higher insurance rates. E. Resistant to flood damage. All new construction and substantial improvements, including manufactured homes, must be constructed with materials and utility equipment resistant to SI,R2020-00006 Milton Court Water Linc 3 flood damage. F. Minimize flood damage. All new construction and substantial improvements, including manufactured homes, must be constructed using methods and practices that minimize flood damage. The scope of work is located in the FEMA special flood hazard area, but is not located in the floodway. The applicant proposes to install an approximately 400-foot-long, 12-inch water line through the subject properties,which will result in minimal ground disturbances or land form alterations involving less than 50 cubic yards of material in the special flood hazard area. The applicant's proposal does not involve any new structures or buildings. The new water line will be placed underground via directional boring, and the applicant submitted plans that were certified by a registered professional engineer. Accordingly, staff finds that the new water line will be constructed using methods and practices that minimize flood damage. These standards are met. H. Water supply systems. All new and replacement water supply systems must be designed to minimize or eliminate infiltration of floodwater into the system. The new water line will be placed underground and will be installed via directional boring.The applicant also submitted plans that were certified by a registered professional engineer,which demonstrate that the new water line will be designed to minimize or eliminate infiltration of floodwater into the system. This standard is met. 18.510.070 Sensitive Lands Applications B. Within the special flood hazard area. The approval authority will approve or approve with conditions an application for sensitive lands review within the special flood hazard area when all of the following criteria are met: 1. Compliance with all of the applicable requirements of this title; As demonstrated through the findings in this decision, the applicant's proposal is in compliance with all applicable requirements of this Title. This standard is met. 2. Land form alterations must preserve or enhance the special flood hazard area storage function and maintenance of the zero-foot rise floodway must not result in any encroachments, including fill, new construction, substantial improvements and other development unless certified by a registered professional engineer that the encroachment will not result in any increase in flood levels during the base flood discharge; a. If in the floodway and no-rise requirement is met,the development will comply with all applicable flood hazard reduction provisions. The subject site is located in the FEMA special flood hazard area,but is not located in the floodway. The new water line will be placed underground via directional boring, and will result in minimal ground disturbances or land form alterations involving less than 50 cubic yards of material in the special flood hazard area. The applicant also submitted plans that were certified by a registered professional engineer, which demonstrate that the new water line will be designed to preserve the special flood hazard area storage function, and will not result in any increase in flood levels during the base flood discharge. This standard is met. 3. Land form alterations or developments within the special flood hazard area are allowed only in areas designated as commercial or industrial on the comprehensive plan land use map, except that alterations or developments associated with community service uses, utilities, or public support facilities are allowed on residentially zoned properties subject to S].R2020-00006 Milton Court Water line 4 applicable zoning standards; The subject site is designated as Open Space on the Tigard Comprehensive Plan Land LTse Map,and is zoned Parks and Recreation (PR). The proposal is for a utility, and an underground basic utility is allowed in the PR Zone.This standard is met. 4. Where a land form alteration or development is allowed to occur within the special flood hazard area it will not result in any increase in the water surface elevation of the 100-year flood; The new water line will be placed underground via directional boring, and will result in minimal ground disturbances or land form alterations involving less than 50 cubic yards of material in the special flood hazard area. The applicant also submitted plans that were certified by a registered professional engineer, which demonstrate that the new water line will not result in any increase in the water surface elevation of the 100-year flood.

A tributary (referred to as Tributary 1) to Fanno Creek was delineated within the study area boundary. Tributary 1 is a perennial tributary,with less than 25%slopes,requiring a 50-foot wide vegetated corridor. A portion of the vegetated corridor associated with Tributary 1 extends onto the project area. The project consists of extending a City of Tigard 12-inch water line to an existing water line off-site on Tax Lot 1500 of Tax Map 2S 101.The water line will be installed by boring under the vegetated corridor, requiring no permanent vegetated corridor disturbance. However, construction access may require temporary vegetated corridor disturbance, which will be enhanced to good condition upon project completion.The project will meet all conditions listed under allowed use per Section 3.05.5 of Clean Water Services (CWS) April 2017 R&O Design and Construction Standards (17-05). The project will not require permanent impacts to the vegetated corridor. This report has been prepared to meet standard site assessment requirements listed under Chapter 3 of the April 2017 R&O Design and Construction Standards (17-05). The signed Sensitive Areas Certification (SAC)form is included in Appendix E. Existing Conditions and Background The project site is situated north of the SW Milton Court stub and south of the Southern Pacific Railroad/Metro railroad tracks.Tax Lot 6100 is owned by the City of Tigard and Tax Lot 100 is owned by Metro.The project site is forested with no development.The vegetation within the study area is dominant in red alder(Alnus rubra),Oregon ash (Fraxinus latifolia), Himalayan blackberry(Rubus armeniocus), and common timothy (Phleum pretense). Tributary 1 is located in the western portion of the study area and flows east to west. The tributary is piped within the project site boundary. Topography gently slopes westerly towards off-site Fanno Creek. Fanno Creek is greater than 50 feet from the project area boundary. According to the Natural Resource Conservation Service (NRCS)Washington County Area soil survey and County hydric soil list, the site is mapped as having non-hydric (Unit 1) Aloha silt loam and non-hydric McBee silty clay loam (Unit 30) (attached Figure 3). According to the City of Tigard's Local Wetland Inventory Map (LWI) map, no wetlands or waters are mapped in the study area (attached Figure 4). Water Quality Sensitive Areas Methodology Pacific Habitat Services (PHS) conducted a wetland delineation of the study area in February and March 2018.The wetland and waters delineation was concurred by the Oregon Department of State Lands(DSL) per DSL File No. WD#2018-0674. The PHS delineation within the study area is shown on Figures 6C-2 in WD#2018-0674. The wetland delineation concurrence letter and PHS report are included as Appendix A. The concurred water boundary is shown in attached Figure 5. AKSCity of Tigard Milton Court Water Main-Tigard August 2019 Natural Resource Assessment(AKS Job 5703-05) Page 1 AKS Natural Resource Specialists Jessica Imbrie and Haley Smith, MS,conducted a site visit on January 30, 2019,to determine the condition of the on-site vegetated corridor.A second site visit was conducted by Haley Smith on June 13, 2019 to confirm the stream flow duration of Tributary 1. Summary of Water Quality Sensitive Areas Tributary 1 Tributary 1 originates from a culvert under the Southern Pacific railroad track,flowing southerly to Fanno Creek.The channel contained+3 inches of continuous flow during the January 30,2019 and June 13,2019 site visits, confirming the tributary's perennial status. Macroinvertebrates were also observed within the channel during both site visits. Extent of the Vegetated Corridor The slopes adjacent to perennial Tributary 1 are less than 25%,requiring a 50-foot wide vegetated corridor buffer. Representative slope measurements and the extent of the vegetated corridor are shown on attached Figure 5. An existing 5-foot wide gravel pedestrian trail extends through a portion of the vegetated corridor. Existing Condition of the Vegetated Corridor The existing condition of the vegetated corridors within the study area was determined according to the CWS vegetated corridor standards in Section 3.03.3,Table 3-1.The CWS vegetated corridor standards are based on the presence of tree canopy and percent cover of native trees,shrubs, and groundcover.Three vegetated corridor communities were documented within the study area as documented by vegetated corridor(VECO) Plots A-C.The location of the vegetated corridor plots are shown on Figure 5.The VECO Plot data sheets are included in Appendix B. Representative photographs of the existing conditions of the vegetated corridor are included in Appendix D. VECO Plot A is between the two daylighted sections of Tributary 1.The vegetation community consists of red alder (Alnus rubra, FAC), Oregon ash (Fraxinus latifolia, FACW), shrub cover dominant in invasive Himalayan blackberry (Rubus armeniacus, FAC), and an herbaceous layer of common timothy (Phleum pretense, FAC)and pineland sword fern(Polystichum munitum,FACU).VECO Plot A contains a tree canopy with less than 50%cover;therefore,the vegetated corridor associated with VECO Plot A was determined to be in degraded condition. VECO Plot B is located along the left bank of Tributary 1. The vegetation community consists of a tree canopy dominant in red alder(FAC)and Oregon ash (FACW),shrub cover dominant in invasive Himalayan blackberry (FAC), and an herbaceous layer dominant in common timothy (FAC). VECO Plot B had a tree canopy cover of less than 50% and a native cover of 50%; therefore, the vegetated corridor associated with VECO Plot B was determined to be in marginal condition. VECO Plot C is located along the right bank of Tributary 1. The vegetation community consists of a tree canopy dominant in Douglas-fir(FACU),shrub cover dominant in invasive Himalayan blackberry(FAC),and an herbaceous layer dominant in piggyback-plant (Tolmiea menziesii, FAC). The groundcover was predominantly leaf litter. VECO Plot C had a tree canopy cover of more than 50% and a native species cover of more than 80%;therefore,the vegetated corridor associated with VECO Plot C was determined to be in good condition. AK9City of Tigard Milton Court Water Main-Tigard August 2019 Natural Resource Assessment(AKS job 5703-05) Page 2 Project Project Overview The project will extend a new 12-inch water line from SW Milton Court through the project area via boring to avoid ground disturbance to vegetated corridor. Boring entry and exit holes are placed outside of vegetated corridor. The project adheres to CWS Section 3.05.5 Utility Infrastructure for allowed uses within the vegetated corridor.The Site Plan is included as Figure 6.The project will not impact the adjacent tributary. The project will not require the removal of any native trees greater than 6-inch diameter at breast height (DBH) within the vegetated corridor. No permanent vegetated corridor impacts will occur for this project. Temporary vegetated corridor impacts will be restored and enhanced to good condition. Vegetated Corridor Enhancement The project can be described as a linear development project, requiring enhancement per Section 3.12(a) of CWS R&0 17-5. The applicant does not own or control all of the project tax lots; therefore, the remaining vegetated corridor within in the limits of the permanent easement will be enhanced to good condition.Temporary impacts to the vegetated corridor will be restored and enhanced to good condition. The planting specification table is included in Appendix D.The location of the enhancement planting area is shown on attached Figure 6.

Please note that the four study areas include only a portion of the tax lots described above (see the attached table and maps). Based upon the information presented in the report, we concur with the wetland and waterway boundaries as mapped in Figures 6A, 6A-1, 6A-2, 6B, 613-1, 6 B-2, 6C, 6 C-1, 6 C-2, 6D, 6 D-1, 6 D-2 of the report. Please replace all copies of the preliminary wetland maps with these final Department-approved maps. Within the study areas, fifteen wetlands (Wetland A-O), totaling approximately 2.76 acres, Fanno Creek and Tributary 1 were identified. All features are subject to the permit requirements of the state Removal-Fill Law. Fanno Creek is an essential salmonid stream. Therefore, fill or removal of any amount of material within the OHWL and hydrologically-connected wetlands (Wetlands D, E, I, J, K, and L) may require a state permit. In all the other wetlands, and Tributary 1, a state permit is required for cumulative fill or annual excavation of 50 cubic yards or more in wetlands or below the ordinary high-water line (OHWL) of the waterway (or the 2-year recurrence interval flood elevation if OHWL cannot be determined). This concurrence is for purposes of the state Removal-Fill Law only. Federal or local permit requirements may apply as well. The Army Corps of Engineers will determine jurisdiction for purposes of the Clean Water Act. We recommend that you attach a copy of this concurrence letter to both copies of any subsequent joint permit application to speed application review. Please be advised that state law establishes a preference for avoidance of wetland impacts. Because measures to avoid and minimize wetland impacts may include reconfiguring parcel layout and size or development design, we recommend that you work with Department staff on appropriate site design before completing the city or county land use approval process. This concurrence is based on information provided to the agency. The jurisdictional determination is valid for five years from the date of this letter unless new information necessitates a revision. Circumstances under which the Department may change a determination are found in OAR 141-090-0045 (available on our web site or upon request). In addition, laws enacted by the legislature and/or rules adopted by the Department may result in a change in jurisdiction; individuals and applicants are subject to the regulations that are in effect at the time of the removal-fill activity or complete permit application. The applicant, landowner, or agent may submit a request for reconsideration of this determination in writing within six months of the date of this letter. Thank you for having the site evaluated. Please phone me at 503-986-5246 if you have any questions.

INTRODUCTION Pacific Habitat Services, Inc. (PHS)conducted a wetland delineation encompassing four separate study areas in Tigard, Oregon. Each of the four is the location of potential pedestrian/bike trail construction or improvements. The study sub-areas were roughly defined as extending 50 to 100 feet along either side of initial planned trail alignments. The study area boundaries were, however, subject to land ownership, existing easements, streets, and railways. Each of the four study sub-areas has been given a descriptive site name to facilitate site identification, with the intent of clarifying which portion of the overall project is being identified and/or discussed. The most northerly of the sub-areas is Woodard Park to Grant Avenue, with the study area beginning at the proposed northern extent of new trail in Woodard Park. To the south is Ash Avenue to Hall Boulevard,where the trail is proposed for realignment within Fanno Creek Park. The third section, Tigard Library to Bonita Road, begins just east of the Tigard City Library. The southernmost section is 85th Avenue to Ki-a-Kuts Bridge. This report presents the results of PHS's wetland delineation. Figures, including a map depicting the location of wetlands within the study area, are located in Appendix A. Data sheets documenting on- site conditions are provided in Appendix B. Ground-level photos of the study area are in Appendix C. A discussion of the wetland delineation methodology is provided in Appendix D for the client. II. RESULTS AND DISCUSSION A. Landscape Setting and Land Use Each of the four project sub-areas includes trail sections that begin within or adjoin public parks or other open spaces. The Woodard Park to Grant Avenue section begins in a developed portion of Woodard Park. Land use north of the park is predominantly light industrial and to the south, residential. Individual trees, as well as those in small stands and along Fanno Creek, are predominately Oregon ash (Fraxinus latifolia, FACW) or Oregon white oak(Quercus garryana, UPL). The understory is mowed lawn within the developed portion of the park,transitioning to mixed grassland and small stands of shrubs to the south. South of the point where Fanno Creek crosses through the Woodard Park to Grant Avenue sub-area, the forest cover expands with an understory including native shrubs and small trees as well as Himalayan blackberry (Rubus armeniacus,FAC). The Ash Avenue to Hall Boulevard sub-area is located entirely within Fanno Creek Park. Lands to the north include light industrial lots, with residential properties south of the park, about 250 to 300 feet from the southern sub-area boundary. Fanno Creek Park is criss-crossed by Fanno Creek and existing sections of the Fanno Creek Trail. The remaining portions of the sub-area are forested; including a diverse mix of native deciduous and evergreen trees. The understory is similarly dominated by native species, though Himalayan blackberry is common in some areas. Pacific Habitat Services,Inc. Wetland Delineation for the Fanno Creek Trail in Tigard,Oregon/PHS#5854 Page 1 The Tigard Library to Bonita Road sub-area begins just east of the point where the current southern terminus of the Fanno Creek Trail reaches the Tigard Public Library. The sub-area begins at the west bank of Fanno Creek at the location of a former farm bridge crossing and then traverses along a berm that likely provided vehicular and/or farm access across the Fanno Creek floodplain from lands to the east. The berm is vegetated primarily with Himalayan blackberry and English hawthorn (Crataegus monogyna, FAC) ,though Oregon ash, Oregon white oak, and black cottonwood/balsam poplar(Populus balsamifera, FAC) are common in the floodplain adjoining the berm. The proposed alignment then passes out of the floodplain and across a meadow dominated by common pasture and lawn grasses. The southern half of the Tigard Library to Bonita Road section is a mixed oak, ash, Douglas fir(Pseudotsuga douglasii, FACU) forest that continues to the northern terminus of SW Milton Court. The 85th Avenue to Ki-a-Kuts Bridge sub-area is located between two sections of an existing multi-use trail that begins in Cook Park, to the west. The potential trail alignment is located within the eastern extent of a land parcel formerly utilized as farmland that has, in the last decade, been under restoration as a native wet meadow. The wetland restoration extends to the west a distance of 500 to 700 feet. The eastern limits of the study area are defined by railroad right-of-way(ROW) and its associated fill embankment. B. Site Alterations Though some portion of each study sub-area has been subject to past alteration, no recent site alterations were evident. C. Precipitation Data and Analysis The study areas were initially delineated during the winter and early spring of 2018. Wetland boundaries were subsequently confirmed later in the spring, with a predominance of data collected at that time. Precipitation on the date of field work, within the previous two week period and the observed and percent of normal for the water year to date are included in Table 1.

The table also compares the observed precipitation to the normal precipitation range, as identified in the Natural Resources Conservation Services (MRCS)WETS table for the Portland- Hillsboro Airport. As shown in Table 2, observed precipitation was somewhat below normal on a month to month basis, with January at approximately normal, and April a bit above normal. Despite the variability, onsite hydrologic conditions were still considered to be typical for this time of year.

Source:AgACIS for Washington County Monthly summarized data for 2017 and 2018(http://agacis.rcc- acis.org/41067) D. Methods PHS delineated the limits of jurisdictional wetlands in the study area based on the presence of wetland hydrology, hydric soils, and hydrophytic vegetation, in accordance with the Routine On- site Determination, as described in the Corps of Engineers Wetland Delineation Manual, Wetlands Research Program Technical Report Y-87-1 ("The 1987 Manual") and the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Western Mountains, Valleys, and Coast Region. PHS conducted the initial wetland delineations over four separate dates in February and March 2018 (see Table 1 above). Each site was then returned to later in the spring for the predominance of data collection, and to confirm the previously delineated wetland and waterway boundaries. In total each sub-area was visited two or three times, which allowed for confirmation of resource boundaries between late winter and mid to late spring,though ultimately no boundaries were modified from the originally delineated boundaries. The majority of wetlands across all sub-areas were largely defined by natural and generally subtle topographic breaks that corresponded to a lack of hydrologic indicators and hydric soils at the wetland/upland boundary(including Wetlands C through M). Many of these wetlands were in floodplain areas along Fanno Creek and there was often little variability in vegetation patterns just above and below the wetland boundary. Wetlands A and B are in areas of lawn in Woodard Park and the wetland/upland boundary was reflected by the presence/absence of oxidized rhizospheres in the soil profile. The boundaries of Wetlands N and O generally corresponded to the limits of grade breaks associated with railroad embankment(along Wetland N) as well as a an upland berm that was generated as part of a wetland enhancement project initiated at the site in 2009. Pacific Habitat Services,Inc. Wetland Delineation for the Fanno Creek Trail in Tigard,Oregon/PHS#5854 Page 3 The sections of ordinary high water (OHW)along Fanno Creek in the Woodard Park to Grant Avenue, Ash Avenue to Hall Boulevard and Tigard Library to Bonita Road sub-areas were flagged based on field indicators; primarily litter and debris lines, and evidence of scour. E. Description of All Wetlands and Other Non-Wetland Waters PHS identified the potentially jurisdictional limits of wetlands and other waters within each of the four study sub-areas. Descriptions of the delineated resources are provided below. Fanno Creek and Tributary 1 Fanno Creek is a perennial tributary to the Tualatin River that flows in and out of the three northern sub-areas; Woodard Park to Grant Avenue, Ash Avenue to Hall Boulevard, and Tigard Library to Bonita Road.A combined total of approximately 1.6 acres of main channel and associated tributaries of Fanno Creek are located within the boundaries of these three areas. The Cowardin class is riverine, lower perennial, unconsolidated bottom, permanently flooded (R2UBH) and the HGM class is Riverine Flow-Through (RFT). Riparian vegetation along the several reaches of creek can be typified by the following species; Oregon ash,big leaf maple (Acer macrophyllum,FACU), Oregon white oak, willow(Salix, sp. (FAC-FACW)),red-osier dogwood (Cornus alba, FACW), Himalayan blackberry, and reed canarygrass(Phalaris arundinacea, FACW). Substrates within Fanno Creek primarily consist of silt loam and clays. The creek is, however, somewhat incised along sections within and bordering the three northern sub-areas resulting in steep and often poorly vegetated banks; in most areas these banks are relatively stable. Bank stability does appear to be poor at a sharp bend in the creek just west of Wetland L in the Tigard Library to Bonita Road sub-area.This is the result of the concentration of flows along the outside of a 180-degree bend in the creek. Fanno Creek's high flow channel is located in the Ash Avenue to Hall Boulevard sub-area. It conveys seasonal overflow from Fanno Creek at a point where the high flows,just below ordinary high water, jump the outer creek bank. The channel maintains a relatively direct flow path to the southeast, flowing back into the creek just west of the pedestrian bridge at the eastern limits of the Ash Avenue to Hall Boulevard sub-area; a linear distance of approximately 130 feet from its upstream overflow point. Tributary 1 is a perennial tributary of Fanno Creek located near the eastern limits of the Tigard Library to Bonita Road sub-area. It consists of a very short daylighted section of creek confined between a culvert that conveys flow from beneath the railroad tracks to the northeast, and a second culvert. This second culvert is approximately 75 feet long and was presumably installed to provide access to lands to the north, which are otherwise inaccessible due to lack of bridges over Fanno Creek and its floodplain, or the railroad tracks.Tributary 1 flows directly into Fanno Creek near the western limits of the study area, and is 5,793 square feet (0.13 acres)within the study area. Pacific Habitat Services,Inc. Wetland Delineation for the Fanno Creek Trail in Tigard,Oregon/PHS#5854 Page 4 Woodard Park to Grant Avenue Sub-area Wetland A Wetland A is a small forested wetland in Woodard Park. It is dominated by Oregon ash with an understory of Douglas' meadowsweet (Spiraea douglasii, FAC) and snowberry (Symphoricarpos albus, FACU). As the outer limits of the wetland are mowed, herbaceous vegetation in those areas is dominated by mixed lawn grasses, dandelion (Taraxacum officinale, FACU), and clover(Trifolium sp., (FAC)). In the un-mowed, central portion meadow foxtail (Alopecurus pratensis, FACW) and creeping buttercup (Ranunculus repens, FAC)are common. The Cowardin classification is palustrine forested, saturated/semipermanent/seasonal (PFOY). The HGM classification is Flats. The total area of Wetland A is 2,854 square feet(0.07 acres). Wetland B Wetland B is a small herbaceous wetland dominated by mixed lawn grasses and weedy forbs; primarily annual bluegrass (Poa annua, FAC) and white clover(Trifolium repens, FAC). It is located on a subtle slope north of Fanno Creek. The wetland is located in an actively utilized portion of Woodard Park and is regularly mowed. The Cowardin classification is palustrine emergent, seasonally saturated (PEMY). The HGM classification is Slope. The total area of Wetland B is 410 square feet(0.01 acres). Wetland C Wetland C is located in a shallow depression in the floodplain north of Fanno Creek. Small Oregon ash trees and shrubs cover about half the wetland, with the herbaceous component dominated by reed canarygrass, colonial bentgrass (Agrostis capillaris,FAC), bird's foot trefoil (Lotus corniculatus, FAC), creeping buttercup and curve-pod yellowcress(Rorippa curvisiliqua, OBL). This is scrub- shrub, seasonally saturated wetland (PSSY)with some short-lived, seasonal ponding likely but not common. Despite the subtle depression in the landscape, the HGM classification for the entirety of the wetland is Slope. The total area of Wetland C is 7,853 square feet(0.18 acres). Wetland D Wetland D is located in the lowest elevations of the floodplain along this reach of Fanno Creek. The east and west extents include unvegetated channels that provide seasonal flow-through when water levels in Fanno Creek begin to approach bankfull flows. The central,vegetated portion of the wetland is dominated by reed canarygrass and colonial bentgrass. Along its southern and west limits Sitka and Pacific willow trees and shrubs (Salix sitchensis and S. lasiandra, both FACW) are common. The Cowardin classification is palustrine emergent and shrub, seasonally flooded (PEM/SSC). The primary HGM classification is Riverine Flow-Through (RFT), though there is also a seasonal groundwater component to the hydrology. The total area of Wetland D is 11,339 square feet (0.26 acre). Wetland E Wetland E is roughly defined by boundaries of an overflow channel that may in fact have been the most recent alignment of Fanno Creek prior to the construction of Grant Avenue. The southern extent is located south of the study area. Due to seasonal flooding, the lowest elevations are not well vegetated. Along its boundaries, and along shallower portions along its length, woody vegetation dominates; primarily Oregon ash, red-osier dogwood, and roses (Rosa sp. (FAC)). Pacific Habitat Services,Inc. Wetland Delineation for the Fanno Creek Trail in Tigard,Oregon/PHS 4 5854 Page 5 Reed canarygrass is present along the northern extent where water levels are a bit shallower. The two sections of Wetland E within the study area are separated by a narrow access road, which includes a small culvert that maintains a direct hydrologic connection. During high water along Fanno Creek, Wetland E, the western extent of the old overflow channel, and much of the adjoining floodplain are inundated in this area. The Cowardin classification is palustrine forested, seasonally flooded (PFOC). The primary HGM classification RFT. The total area of Wetland E is 7,383 square feet(0.18 acre). Ash Avenue to Hall Boulevard Sub-area Wetlands F.G.and H Wetlands F, G and H are each located near the existing Fanno Creek Trail, with surface and subsurface hydrology to/within the wetlands likely affected by the trail's proximity. Such affects include stormwater inputs from the trail, but also the retarding of infiltration or flow-through as a result of changes to topography that would have occurred decades ago, when the trail was originally constructed. These are forested wetlands; variously including Oregon ash, Pacific willow, black cottonwood and even Oregon white oak. The understory is similarly variable, including dogwood, meadowsweet, rose, as well as ash saplings. Herbaceous cover is sparse, likely the result of the dense tree and shrub cover. Documented species include lamp rush (Juncus effusus, FACW), reed canarygrass and poverty rush (Juncus tenuis.FAC). The Cowardin classification of each is palustrine forested, seasonally flooded/saturated (PSSE). Wetlands F and G have an HGM classification of Slope, and Wetland H is Flats. Wetland F extends beyond the study area, with only 604 square feet(0.01 acres) on-site. Wetland G is 2,793 square feet (0.06 acres) and Wetland H is 1,095 square feet(0.03 acres). Wetland I Wetland I includes an area along the north bank of Fanno Creek where topography is lower than the common top of bank elevation. This results in periods of seasonal ponding whenever creek flows approach the elevation of OHW. Despite the inundation, soils show little evidence of hydric activity. This is believed to result from the variability of inundation and prevalence of such events occurring during the winter, when biologic and chemical activity in the soils would be lower. The area is primarily vegetated by Oregon ash, Douglas' meadowsweet, and rose. The Cowardin classification is palustrine scrub-shrub, seasonally flooded (PSSC). The HGM classification is Riverine Impoundment(RI). The total area of Wetland I is 2,048 square feet(0.05 acres). Wetland J Wetland J is a small forested wetland located just upslope from Wetland 1. Topography suggests that overbank flooding from Fanno Creek flows through Wetland I and into this area. Following the reduction of floodwaters there is enough topographic variation in the vicinity of Wetland J to retain surface water for a longer duration than adjoining areas. Sample Point 25, in the wetland, and adjoining upland point 24 both include clay soils at depth. Clay soils were not commonly encountered in other sample points in this sub-area, suggesting that subsurface conditions favor the retention of both surface and groundwater for a greater duration than the better drained silty soils more common to this area. Like most of the wetlands in Fanno Creek Park, dominant woody vegetation includes Oregon ash, rose, and meadowsweet. The herbaceous component includes annual bluegrass, meadow foxtail and colonial bentgrass. The Cowardin classification is palustrine forested, seasonally flooded/saturated (PFOE). The HGM classification is Flats. The total area of Wetland J is 1,146 square feet (0.03 acres). Pacific Habitat Services,Inc. Wetland Delineation for the Fanno Creek Trail in Tigard,Oregon/PHS#5854 Page 6 Wetland K Wetland K includes a large mixed forest, shrub and herbaceous wetland located south of Fanno Creek. Portions of the wetland remain shallowly inundated year round but seasonally, when water depths increase, inundation extends north, resulting in surface discharge across the wetland,through culverts under the existing path (and sometimes over the path) and into a swale that discharges directly into Fanno Creek(near Sample Point 30). The western extent of Wetland K is herbaceous, and is dominated by lamp rush, impatiens (Impatiens capensis, FACW) and short stem bulrush (Schoenoplectus tabernaemontani, OBL). Reed canarygrass and colonial bentgrass are common, and cattails(Typhia, sp., (FACW)) are locally dominant. The eastern portion of Wetland K is largely dominated by Oregon ash. South of the existing path,the understory includes ash saplings, colonial bentgrass and impatiens. The northern extent(north of the path), where the wetland is more confined, is dominated by a shrubby understory including Douglas' meadowsweet and red-osier dogwood,with reed canarygrass common where the cover of shrubs is reduced. The Cowardin classification is palustrine forested and emergent, seasonally flooded (PFO/EMC). The HGM classification is Slope. Though only a part of a much larger wetland that extends off-site to the south, the on-site portion is 14,579 square feet(0.33 acres). Tigard Library to Bonita Road Subarea Wetland L Wetland L is located in a backwater channel of Fanno Creek. The on-site portion is a small part of a wetland area several acres in size.Approximately 1,152 square feet (0.03 acres)of the wetland is located within the study. This includes two portions located north and south of a small culvert beneath a berm that historically provided access to farmland on both sides of Fanno Creek. Vegetation within Wetland L consists predominantly of red-osier dogwood, English hawthorn and reed canarygrass. Oregon ash and impatiens are also present. The Cowardin class is forested (PFOC), and the HGM class is Slope, though seasonal high water in Fanno Creek does increase water depths and flood duration as a result of backwatering(riverine impounding). Wetland M Wetlands M is an ash dominated wetland in a subtle depression. The understory includes few herbaceous species but is rather dominated by ash saplings, roses, Pacific ninebark(Physocarpus capitatus, FACW), and trailing blackberry (Rubus ursinus, FACU). The Cowardin classification is PFOE. The HGM classification is Slope. The total area of Wetland M is 859 square feet(0.02 acres). 85th Avenue to Ki-a-Kuts Bridge Sub-area Wetlands N and O Wetlands N and O constitute the eastern limits of wetlands located within former agricultural lands located between Cook Park, to the west, and a railroad ROW. Clean Water Services (CWS) acquired the property for expansion of an existing wastewater treatment facility located north of the study area. As the southern limits of the property were not suitable for development, CWS has begun restoring a native wet prairie; therefore, Wetland N is primarily herbaceous. The study area,however, includes only the eastern limits of the wetland, which is forested. The forested wetland transitions to an upland forest that covers the lower limits of the railroad embankment that defines the eastern limits of the study area.

The primary source documents for wetland delineations within Oregon is the Corps of Engineers Wetlands Delineation Manual, Technical Report Y-87-1 (Environmental Laboratory 1987) and the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Western Mountains, Valleys, and Coast Region (Version 2.0) (U.S. Army Corps of Engineers, 2010), which are required by both DSL and COE. Waters of This State and Wetland Definition Waters of This State are defined as "all natural waterways, all tidal and non-tidal bays, intermittent streams, constantly flowing streams, lakes, wetlands, that portion of the Pacific Ocean that is in the boundaries of this state, all other navigable and non-navigable bodies of water in this state and those portions of the ocean shore ..." (DSL, 2009). Wetlands are defined as"those areas that are inundated or saturated by surface or ground water at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions" (DSL 2009). Wetland Criteria Based on the above definition, three major factors characterize a wetland: hydrology, substrate, and biota. Wetland Hydrology Wetland hydrology is related to duration of saturation, frequency of saturation, and critical depth of saturation. The 1987 manual defines wetland hydrology as inundation or saturation within a major portion of the root zone (usually above 12 inches),typically for at least 12.5%of the growing season. The wetland hydrology criterion can be met, however, if saturation within the major portion of the root zone is present for only 5%of the growing season, depending on other evidence. The growing season is defined as the portion of the year when soil temperatures at 12.0 inches below the soil surface are higher than biological zero(41 degrees Fahrenheit, 5 degrees Celsius), but also allows approximation from frost-free days, based on air temperature. The growing season for any given study area or location is determined from US Natural Resources Conservation Service, (formerly Soil Conservation Service)data and information. Appendix D—Wetland Definition and Methodology Pacific Habitat Services,Inc. Page 1 Wetland hydrologic indicators include the following: visual observation of inundation or saturation, watermarks, drift lines, sediment deposits, and/or oxidized rhizospheres with living roots. Oxidized rhizospheres are defined as yellowish-red zones around the roots and rhizomes of some plants that grow in frequently saturated soils. Other indicators of hydrology, including algal mats or crust, iron deposits, surface soil cracks, sparsely vegetated concave surface, salt crust, aquatic invertebrates, hydrogen sulfide odor,reduced iron, iron reduction in tilled soils, and stunted or stressed plants can also be used to determine the presence of wetland hydrology. Wetland Substrate (Soils) Most wetlands are characterized by hydric soils. Hydric soils are those that are ponded, flooded, or saturated for long enough during the growing season to develop anaerobic conditions. Periodic saturation of soils causes alternation of reduced and oxidized conditions,which leads to the formation of redoximorphic features (gleying and mottling). Mineral hydric soils will be either gleyed or will have bright mottles and/or low matrix chroma. The redoximorphic feature known as gley is a result of greatly reduced soil conditions, which result in a characteristic grayish, bluish or greenish soil color. The term mottling is used to describe areas of contrasting color within a soil matrix. The soil matrix is the portion of the soil layer that has the predominant color. Soils that have brightly colored mottles and a low matrix chroma are indicative of a fluctuating water table. Hydric soil indicators include organic content of greater than 50%by volume, and/or presence of redoximorphic features and dark soil matrix, as determined by the use of a Munsell Soil Color Chart. This chart establishes the chroma, value and hue of soils based on comparison with color chips. Mineral hydric soil must meet one of the 16 definitions for hydric soil indicators, or be classified as a"problem soil"in the Regional Supplement. Wetland Biota(Vegetation) Wetland biota is defined as hydrophytic vegetation. A hydrophyte is a plant species that is capable of growing in substrates that are periodically deficient in oxygen as a result of saturated soil conditions. The U.S. Fish and Wildlife Service, in the National List of Plant Species that Occur in Wetlands, has established five basic groups of vegetation based on their frequency of occurrence in wetlands. These categories, referred to as the "wetland indicator status", are as follows: obligate wetland plants(OBL), facultative wetland(FACW), facultative (FAC), facultative upland (FACU), and obligate upland (UPL). Table 1 gives a definition of the plant indicator codes. Table 1. Description of Wetland Plant Indicator Status Codes Indicator Code Status OBL Obligate wetland. Plants that always occur in standing water or in saturated soils. FACW Facultative wetland. Plants that nearly always occur in areas of prolonged flooding or require standing water or saturated soils but may, on rare occasions,occur in non-wetlands. FAC Facultative.Plants that occur in a variety of habitats, including wetland and mesic to xeric non-wetland habitats but commonly occur in standing water or saturated soils. FACU Facultative upland. Plants that typically occur in xeric or mesic non-wetland habitats but may frequently occur in standing water or saturated soils. UPL Obligate upland. Plants that rarely occur in water or saturated soils. Appendix D—Wetland Definition and Methodology Pacific Habitat Services,Inc. Page 2 Observations of hydrology, soils, and vegetation, were made using the 'Routine On-study area" delineation method as defined in the 1987 manual and the Regional Supplement for areas that were not currently in agricultural production. One-foot diameter soil pits were excavated up to 24 inches and soil profiles were examined for hydric soil and wetland hydrology field indicators. In addition, a visual absolute-cover estimate of the dominant species of the plant community was performed using soil pit locations as a center of reference. Dominant plant species are based on estimates of absolute cover for herbaceous, and shrub species within a 5-foot radius of the sample point, and basal area cover for tree and woody vine species within a 30 foot radius of the sample point. Plant species in each vegetative layer, which are estimated at less than 20%of the total cover, are not considered dominant. The wetland indicator status is then used to determine if there is an overall dominance(greater than 50%) of wetland or upland plant species. If less than 50%of the dominant species are hydrophytic, then the prevalence index may be used to determine if the subdominant species are hydrophytic. If the prevalence index is less than or equal to three, hydrophytic vegetation criterion is met. During data collection,the soil profiles were examined for hydric soil and wetland hydrology field indicators. Plant species and cover were recorded. Data was recorded on standard data sheets, which contain the information specified in the 1987 Corps Manual and the Regional Supplement.

If bare root plants are used, they must be planted during the late winter/early spring dormancy period. Planting Notes (per CWS Design & Construction Standards, Appendix A Planting Requirements,April 2017): 1) Container stock shall be installed only from February through May 1 and October 1 through November 15. Bare root stock shall be installed only from December 15 through April 15. Plantings outside these times may require additional measures to ensure survival which shall be AK9City of Tigard Milton Court Water Main Extension August 2019 Vegetated Corridor Enhancement Planting Specifications Pagel specified on the plans. 2) All non-native invasive vegetation shall be removed from planting areas prior to installing native enhancement plantings. Invasive species control shall be consistent with Clean Water Services' Integrated Vegetation and Animal Management Guide. 3) Appropriate plant selection,along with adequate site preparation and maintenance, reduces the need for irrigation. However, unless site hydrology is currently adequate,a District/City approved irrigation system or equivalent(i.e., polymer, plus watering)shall be used during the two-year plant establishment period.Watering shall be at a minimum rate of at least one inch per week from June 15 through October 15. Other irrigation techniques,such as deep watering, may be allowed with prior approval by District staff. 4) Trees,shrubs, and groundcovers planted shall be mulched at a minimum of three inches in depth and 18 inches in diameter,to retain moisture and discourage weed growth around newly installed plant material.Appropriate mulches are made from composted bark or leaves that have not been chemically treated. 5) Depending on site conditions,appropriate measure shall be taken to limit wildlife-related plant damage (see IPM Plan). Maintenance Plan 1) Clean Water Services requires a two-year maintenance period for vegetated corridor enhancement. The enhanced vegetated corridor is to be inspected annually and a minimum of two times during the growing season, by June 1 and September 30. 2) Plant Survival: Clean Water Services'success criterion for vegetated corridor enhancement is 80%survival of tree and shrub plantings during the two years following planting. If any mortality is noted on the site,the factor likely to have caused mortality of the plantings is to be determined and corrected if possible. If survival falls below 80%at any time during the two-year maintenance period,the plantings shall be replaced and other corrective measures,such as mulching or irrigation, may need to be implemented. If replanting is necessary,the maintenance period will be extended for two years from the date of replanting. 3) Invasive species control is to be conducted as needed based on the site inspections. Invasive species include Himalayan blackberry(Rubus ormeniacus), reed canarygrass (Phalaris arundinacea),teasel (Dipsacus fullonum),Canada and bull thistle(Cirsium arvense and C. vulgare),Scotch broom (Cytisus scoparius), purple loosestrife (Lythrum salicaria),Japanese knotweed (Polygonium cuspidatum), morning glory(Convolvulus species),giant hogweed (Heracleum mantegazzianum), English ivy(Hedera helix), nightshade (Solanum species),and clematis(Clematis ligusticifolia and C. vitalba).

The City of Tigard is the project owner. This new pipeline will connect two existing pipeline stubs located in Tigard, Oregon. The project general location is shown in Figure 1. This report presents the project understanding and geotechnical site characterizations, including field explorations and laboratory testing. Engineering design recommendations are not discussed in this report. 2 PROJECT UNDERSTANDING 2.1 Project Description We understand that the City of Tigard wishes to construct a new 12-inch water pipeline that will connect two existing pipeline stubs. The connection will start at an existing 12-inch waterline stub located at the cul-de-sac of SW Milton Court. The new pipeline will extend north through a portion of forested park to another existing waterline stub. This northern stub extends from SW Tech Center Drive under the Tri-Met Westside Express Southern Pacific Railroad tracks. This proposed geotechnical exploration will focus on a portion of the pipe that will be installed using pipe boring or directional drilling. The new pipeline will have approximately 3 to 4 feet of embedment below existing ground. These technologies are being considered for implementation to minimize impacts to trees and to avoid extensive construction in the forested park. 2.2 Site Description The project site is located directly north of the cul-de-sac at the end of SW Milton Court. Between the two waterline stubs is a forested park. The area is part of the Fields Natural Area. Starting at the northern end of the cul-de-sac is a wide hiking trail which leads to the approximate location of the northern waterline stub. The area is highly vegetated with trees,bushes,and grass as shown in Exhibit 2-1. Fanno Creek runs parallel to the planned pipeline approximately 150 feet to the west of the planned alignment. Railroad tracks run parallel to the planned alignment approximately 75 feet to the east of the planned alignment,as shown in Exhibit 2-2. Toward the northern 102404 April 1,2019 1 Bill SHANNON&WILSON SW Milton Court Pipeline Connection Project Geotechnical Data Report end of the alignment a stormwater/tributary culvert runs underneath the railroad tracks, where it daylights into a small pool. It then enters another culvert and crosses the alignment of the new waterline connection. This second culvert outfalls into an open channel/tributary to Fanno Creek. There is a narrow ravine that is approximately 5 feet deep at this tributary outfall. H � r f� Exhibit 2-1:General conditions at the site,near the northern end of Milton Court 4 • �a l y. Exhibit 2-2:Train tracks running parallel to the planned pipeline near HA-3 102404 April 1,2019 2 011 SHANNON&WILSON SW Milton Court Pipeline Connection Project Geotechnical Data Report 2.3 Scope of Service Our geotechnical services for the project consist of the following tasks: ■ Perform a desktop study to evaluate the subsurface conditions and geotechnical hazards; • Perform a geotechnical field exploration,which includes four(4)hand auger borings to a depth of 10 feet or refusal; ■ Perform laboratory testing on soil samples collected during the borings,including up to three (3)Atterberg limit tests and three(3) moisture content tests;and ■ Prepare this Geotechnical Data Report. 3 GEOLOGIC SETTING 3.1 Local Geology The project area is located on a flood plain of Fanno Creek.According to Geologic mapping (Gannett and Caldwell, 1998)the area is underlain by Holocene-age Alluvium. They describe the material as consisting of coarse-and fine-grained deposits along channels and flood plains of the present-day drainage system. During our explorations,we encountered clay, silt and sand within the upper 10 feet, consistent with theses descriptions. 3.2 Geologic Hazards We reviewed available information from the Oregon Department of Geology and Minerals (DOGAMI)HazVu website to provide information regarding general geologic hazard information at the project site. Based on the DOGAMI website, the area is mapped as being susceptible to very strong to severe earthquake ground motion shaking. Furthermore,the site is mapped as having a high risk of liquefaction. Finally,DOGAMI has the area mapped as a low to moderate risk of landslide hazard. This is likely due to the presence of the sloped banks of Fanno Creek and its tributary near the northern end of the new water line alignment. During our site visit,we noted significant amounts of erosion taking place at the outfall of the stormwater/tributary creek culvert. This erosion may eventually lead to localized slumping failures that could affect the outfall if not mitigated. Erosion damage in this area is shown in Exhibit 3-1. 102404 April 1,2019 3 5111 SHANNON&WILSON SW Milton Court Pipeline Connection Project Geotechnical Data Report C Exhibit 3.1: Erosion at the outfall of the stormwaterltributary creek culvert 4 FIELD INVESTIGATION AND LABORATORY TESTING 4.1 Geotechnical Exploration The geotechnical exploration program consisted of four hand auger borings, designated HA-1 through HA-4. The locations of the explorations are shown on Figure 2. The borings were manually excavated to depths ranging from 7 to 10 feet using hand-auger tooling, which creates an approximately 2.5-inch-diameter hole. Representative disturbed samples were collected from the hand-auger cuttings during drilling, sealed to retain moisture,and returned to our laboratory for additional examination and testing. Summary logs of the hand augers are presented in Appendix A. Material descriptions and interfaces on the logs are interpretive, and actual changes may be gradual. 4.2 Laboratory Testing Soil samples obtained during the field explorations were described and identified in the field in general accordance with the Standard Practice for Description and Identification of Soils(Visual-Manual Procedure), ASTM D2488. The specific terminology used is presented in Appendix A, Figure Al. The samples were reviewed in the Shannon& Wilson laboratory. The physical characteristics of the samples were noted, and the field descriptions and identifications were modified,where necessary,in accordance with terminology presented in Appendix A, Figure Al. 102404 April 1,2019 4 -111 SHANNON&WILSON SW Milton Court Pipeline Connection Project Geotechnical Data Report Representative samples were selected for various laboratory tests. We refined our visual- manual soil descriptions and identifications based on the results of the laboratory tests, using elements of the Standard Practice for Classification of Soils for Engineering Purposes (Unified Soil Classification System),ASTM D2487. The refined descriptions and identifications were then incorporated into the Logs of Borings, presented in Appendix A. The soil testing program included moisture content analyses and Atterberg limits tests. This index testing was performed by Shannon&Wilson. Laboratory testing was performed in accordance with applicable ASTM standards, and the results are included in Appendices A and B. General testing procedures and laboratory testing results are further summarized in Appendix B. 5 SUBSURFACE CONDITIONS 5.1 Subsurface Soil Units We grouped the materials encountered in our field explorations into two geotechnical units. Our interpretation of the subsurface conditions is based on the explorations and regional geologic information from published sources. The geotechnical units are as follows: • Fill:Light brown, Sandy Silt(ML). • Alluvium:Dark brown and gray, Lean Clay with trace Sand (CL),brown,green, Silty Sand (GC), and gray,green, poorly-graded Sand with silt. These geotechnical units were grouped based on their engineering properties, geologic origins, and their distribution in the subsurface. The simplified soil strata are interpretive, and variations in subsurface conditions may exist between the borings. Contacts between the units may be more gradational than shown in the profiles and in the Log of Borings in Appendix A. 5.1.1 Fill Fill deposits were encountered in only HA-1. The fill material extended from the ground surface to a depth of about 4 feet below the ground surface.The fill generally consisted of Brown, Sandy Silt(ML). Natural moisture in this material was about 27 percent. 5.1.2 Alluvium Alluvium consisted of Lean Clay(CL),Silty Sand (SM), and Poorly-Graded Sand with Silt (SP). The alluvial deposits were encountered from the ground surface up to 10 feet below the ground surface in HA-2, HA-3 and HA-4. The Alluvium was encountered from 4 feet to 102404 April 1,2019 5 =111 SHANNON&WILSON SW Milton Court Pipeline Connection Project Geotechnical Data Report 10 feet below the ground surface in HA-1. The sand constituent was generally fine to medium grained sand. The natural moisture content ranged from 27 to 37 percent. 5.2 Groundwater Hand auger borings from this project encountered groundwater at every boring. Groundwater levels encountered at the time of borings were found in HA-1, HA-2, HA-3 and HA-4 at estimated depths of 9 feet, 7 feet,6 feet,and 8 feet below the ground surface, respectively. Groundwater levels fluctuate with the season. Generally,groundwater highs occur at the end of the wet season in spring,and groundwater lows occur toward the end of the dry season in the early to mid-fall. 6 REFERENCES Gannett,M.W., and Caldwell,R.R., 1998, Geologic framework of the Willamette lowland aquifer system,Oregon and Washington:U.S. Geological Survey, Professional Paper PP-1424-A.

This appendix describes the techniques used to advance and sample the borings and presents logs of the materials encountered during drilling. A.2 HAND AUGERS Hand-auger borings HA-1 through HA-4 were located and drilled by Shannon &Wilson staff on February 21,2018.The borings were manually excavated to depths ranging from Ito • 10 feet using hand-auger tooling,which creates an approximately 2.7-to 3-inch-diameter hole. Representative disturbed samples were collected from the hand-auger cuttings during drilling, sealed to retain moisture,and returned to our laboratory for additional examination • and testing. A.3 BOREHOLE ABANDONMENT Hand auger borings were backfilled with excavated material. A.4 MATERIAL DESCRIPTIONS In the field, soil samples were described and identified visually in general accordance with ASTM D2488, the Standard Practice for Description and Identification of Soils (Visual- Manual Procedure). Color,relative moisture, degree of plasticity, peculiar odors,and other distinguishing characteristics of the samples were noted. Once returned to the laboratory, the soil samples were re-examined. The field descriptions and identifications were modified as necessary based on laboratory test results and further review of the samples. The specific terminology used in our soil descriptions and identifications is defined in the Soil Description and Log Key,Figure Al. A.5 LOGS OF BORINGS Summary logs of the hand augers are presented in Figures A2 through A5.

The soil-testing program included visual-manual classification and index property tests such as moisture content analyses, and Atterberg limits. These tests are described in the following paragraphs. All test procedures were performed in general accordance with applicable ASTM International standards. The term"general accordance" means that certain local and common descriptive practices and methodologies have been followed. • B.2 MOISTURE (NATURAL WATER) CONTENT • Natural moisture content analyses were performed in accordance with ASTM D2216 on selected soil samples. The natural moisture content is a measure of the amount of moisture in the soil at the time the explorations are performed and is defined as the ratio of water weight to dry soil weight,expressed as a percentage. The results of the moisture content analyses are presented graphically on the Logs of Borings in Appendix A. • B.3 ATTERBERG LIMITS • Atterberg limits were determined for select samples in accordance with ASTM D4318. This analysis yields index parameters of the soil that are useful in soil identification, as well as in a number of analyses,including liquefaction analysis. An Atterberg limit test determines a soil's liquid limit(LL)and plastic limit(PL). These are the maximum and minimum moisture contents at which the soil exhibits plastic behavior. A soil's plasticity index(PI) can be determined by subtracting PL from LL. The LL,PL, and PI of tested samples are presented on Figure 131,Atterberg Limits Results. The results are also shown graphically on the Logs of Borings in Appendix A. For the purposes of soil description, Shannon&Wilson uses the term nonplastic to refer to soils with a PI less than 4,low plasticity for soils with a 102404 April 1,2019 B-1 SW Milton Court Pipeline Connection Project Geotechnical Data Report PI range of 4 to 10,medium plasticity for soils with a PI range of 10 to 20,and high plasticity for soils with a PI greater than 20. • • 102404 April 1,2019 B-2 D 1 -i 3 D 70 z 0 N oAo a 60 2 D Z CH r 0 O 50 ED NOTES a CL 1)Atterberg limits tests were performed in general accordance W 4o with ASTM D4318 unless 0 otherwise noted in the report. z_ 2)Group Name and Group v ■ Symbol are in accordance with ASTM D2488 and are refined in (n 30 accordance with ASTM D2487 awhere appropriate laboratory - tests are performed. 3)Plasticity adjectives used in 20 sample descriptions correspond to plasticity index as follows: MH Or OH -Nonplastic(NP)(<4%) -Low Plasticity(4 to 10%) -Medium Plasticity(10 to 20%) • -High Plasticity(>20%) 10 CL-ML ML r OL o 0 10 20 30 40 50 60 70 80 90 1c0 110 LIQUID LIMIT-LL(%) BORING AND DEPTH GROUP GROUP LL PL PI NAT.

I FIG, BI Geotechnical and Envhonm mal Consu tants SW Milton Court Pipeline Connection Project Geotechnical Data Report Important Information About Your Geotechnical/Environmental Report • • • 102404 April 1,2019 ",0 1 41 eft)r W.' pli } SW Milton Court Pipeline Connection Project Geotechnical Data Report CONSULTING SERVICES ARE PERFORMED FOR SPECIFIC PURPOSES AND FOR SPECIFIC CLIENTS. Consultants prepare reports to meet the specific needs of specific individuals. A report prepared for a civil engineer may not be adequate for a construction contractor or even another civil engineer. Unless indicated otherwise,your consultant prepared your report expressly for you and expressly for the purposes you indicated. No one other than you should apply this report for its intended purpose without first conferring with the consultant. No party should apply this report for any purpose other than that originally contemplated without first conferring with the consultant. THE CONSULTANT'S REPORT IS BASED ON PROJECT-SPECIFIC FACTORS. A geotechnical/environmental report is based on a subsurface exploration plan designed to consider a unique set of project-specific factors. Depending on the project,these may include the general nature of the structure and property involved;its size and configuration; • its historical use and practice;the location of the structure on the site and its orientation; other improvements such as access roads,parking lots,and underground utilities;and the additional risk created by scope-of-service limitations imposed by the client. To help avoid costly problems, ask the consultant to evaluate how any factors that change subsequent to • the date of the report may affect the recommendations. Unless your consultant indicates otherwise,your report should not be used(1)when the nature of the proposed project is changed (for example,if an office building will be erected instead of a parking garage, or if a refrigerated warehouse will be built instead of an unrefrigerated one, or chemicals are discovered on or near the site);(2)when the size,elevation, or configuration of the proposed project is altered;(3) when the location or orientation of the proposed project is modified; (4) • when there is a change of ownership;or(5)for application to an adjacent site. Consultants • cannot accept responsibility for problems that may occur if they are not consulted after factors that were considered in the development of the report have changed. SUBSURFACE CONDITIONS CAN CHANGE. Subsurface conditions may be affected as a result of natural processes or human activity. Because a geotechnical/environmental report is based on conditions that existed at the time of subsurface exploration,construction decisions should not be based on a report whose adequacy may have been affected by time. Ask the consultant to advise if additional tests are desirable before construction starts;for example,groundwater conditions commonly vary seasonally. Construction operations at or adjacent to the site and natural events such as floods, earthquakes, or groundwater fluctuations may also affect subsurface conditions and,thus, the continuing adequacy of a geotechnical/environmental report. The consultant should be 102404 April 1,2019 II-1 SW Milton Court Pipeline Connection Project Geotechnical Data Report kept apprised of any such events and should be consulted to determine if additional tests are necessary. MOST RECOMMENDATIONS ARE PROFESSIONAL JUDGMENTS. Site exploration and testing identifies actual surface and subsurface conditions only at those points where samples are taken. The data were extrapolated by your consultant,who then applied judgment to render an opinion about overall subsurface conditions. The actual interface between materials may be far more gradual or abrupt than your report indicates. Actual conditions in areas not sampled may differ from those predicted in your report. While nothing can be done to prevent such situations,you and your consultant can work together to help reduce their impacts. Retaining your consultant to observe subsurface construction operations can be particularly beneficial in this respect. A REPORT'S CONCLUSIONS ARE PRELIMINARY. The conclusions contained in your consultant's report are preliminary,because they must be based on the assumption that conditions revealed through selective exploratory sampling are indicative of actual conditions throughout a site. Actual subsurface conditions can be discerned only during earthwork;therefore,you should retain your consultant to observe actual conditions and to provide conclusions. Only the consultant who prepared the report is fully familiar with the background information needed to determine whether or not the report's recommendations based on those conclusions are valid and whether or not the contractor is abiding by applicable recommendations. The consultant who developed your report cannot assume responsibility or liability for the adequacy of the report's recommendations if another party is retained to observe construction. THE CONSULTANT'S REPORT IS SUBJECT TO MISINTERPRETATION. • Costly problems can occur when other design professionals develop their plans based on misinterpretation of a geotechnical/environmental report. To help avoid these problems,the consultant should be retained to work with other project design professionals to explain relevant geotechnical, geological,hydrogeological, and environmental findings,and to review the adequacy of their plans and specifications relative to these issues. BORING LOGS AND/OR MONITORING WELL DATA SHOULD NOT BE SEPARATED FROM THE REPORT. Final boring logs developed by the consultant are based upon interpretation of field logs (assembled by site personnel),field test results, and laboratory and/or office evaluation of field samples and data. Only final boring logs and data are customarily included in geotechnical/environmental reports. These final logs should not,under any circumstances, be redrawn for inclusion in architectural or other design drawings,because drafters may commit errors or omissions in the transfer process. 102404 April 1,2019 11-2 �1;ft; SW Milton Court Pipeline Connection Project Geotechnical Data Report To reduce the likelihood of boring log or monitoring well misinterpretation, contractors should be given ready access to the complete geotechnical engineering/environmental report prepared or authorized for their use. If access is provided only to the report prepared for you,you should advise contractors of the report's limitations, assuming that a contractor was not one of the specific persons for whom the report was prepared,and that developing construction cost estimates was not one of the specific purposes for which it was prepared. While a contractor may gain important knowledge from a report prepared for another party,the contractor should discuss the report with your consultant and perform the additional or alternative work believed necessary to obtain the data specifically appropriate for construction cost estimating purposes. Some clients hold the mistaken impression that simply disclaiming responsibility for the accuracy of subsurface information always insulates them from attendant liability. Providing the best available information to contractors helps prevent costly construction problems and the adversarial attitudes that aggravate them to a disproportionate scale. READ RESPONSIBILITY CLAUSES CLOSELY. • Because geotechnical/environmental engineering is based extensively on judgment and opinion, it is far less exact than other design disciplines. This situation has resulted in wholly unwarranted claims being lodged against consultants. To help prevent this ■ problem, consultants have developed a number of clauses for use in their contracts, reports, • and other documents. These responsibility clauses are not exculpatory clauses designed to transfer the consultant's liabilities to other parties;rather,they are definitive clauses that identify where the consultant's responsibilities begin and end. Their use helps all parties involved recognize their individual responsibilities and take appropriate action. Some of these definitive clauses are likely to appear in your report, and you are encouraged to read ■ them closely. Your consultant will be pleased to give full and frank answers to your • questions. • The preceding paragraphs are based on information provided by the ASFE/Association of Engineering Firms Practicing in the Geosciences,Silver Spring,Maryland 102404 April 1,2019 11-3 RECEIVE-"r �> SEP 0 2 2020 �.�C'�lll`kl�lteI� Ser�'10E'S CITY 0F TIGARD PLANNING/ENG IN EhM K-Numbe, Service Provider Letter 1 19-002417 This form and the attached conditions will serve as your Service Provider Letter in accordance with Clean Water Services Design and Construction Standards (R&O 19-5, as amended by R&O 19-22).
