It was the first incorporated city in Oregon. The City is the southeasternmost incorporated area within the Metropolitan Urban Growth Boundary. The City's Urban Growth Boundary (UGB) encompasses 7,127 acres (Figure 1). Like many communities in the Metro region, the City is growing at a rapid rate. The Oregon Blue Book (IJevine, 1946) Iists the population as 17,487. The City has conducted periodic review of its comprehensive plan and is upda.ting its inventory of Goa15 resources within the UGB. A map showing an Inventory of Water Resources (the "Yellow Dot" map) was prepaxed by the City in 1982 (City of Oregon City, 1982). The City hired Otak, Incorporated to conduct field investigations in 1993 to complete a wetland inventory for land within the City's UGB. This inventory r�viewed the City's 1982 Inventory of Water Resources sites. A draft Economic, Social, Environmental, and Energy (ESEE) analysis also was prepared. In response to the ESEE analysis, the City created a Water Resources Overlay District to implement protection of significant resources. These products were submitted to the Department of Land Conservation and Development (DLCD), which found that they did not meet the requirements set forth in Columbia Steel Casting v. City of Portland, 314 OR 422, 431 (1992). Neither of the previous inventories was conducted according to the Oregon Administrative Rules (OAR) for local wetland inventories (LWI). Completion of an adequate. LWI will a11ow the City to create and implement protection strategies for natural resources. On April 16, 1997, the DLCD awarded the City a Periodic Review Grant for Phase 1 of a LWI. The City hired Shapiro and Associates, Inc. (SHAPIRO) on Apri128, 199'7 to conduct field investigations of properties with potential wetland areas and produce a draft map of wetland boundaries. A set of draft maps was produced in July 1997, and a revised set of draft maps was produced in December 1997. A second Periodic Review Crrant was awarded to the City in April 1998. On May 20, 1998, the City hired SHAPIRO to complete the LWI (Phase 2). A.n additional 130 properties were investigated, wetlands were mapped in detail, and data were collected. Functional assessments were completed for identified wetlands and riparian areas. This report and updated mapping products have been prepared to satisfy LWI requirements set forth in the OAR. An approved LWI will replace the U.S. Fish and Wildlife Service (IJSFWS) National Wetlands Inventory (NWI) maps that now provide information on where wetlands are located. The LWI also will be incorporated into the sta.tewide wetland inventory. SHAPIRO conducted the study using wetland scientists experienced in conducting LWIs: Dan Cary, Colin MacLaren, Julie Fukuda, John Gordon, and Ke11y Canode. Mr. Cary is a wetland delineator certified by the U.S. Army Corps of Engineers (COE). Ed Strohmaier and Paul Gill, trained wetland delineators, and Peggy O'Neill, a wetland technician, assisted with the inventory. Sylvia Jung, a cartographer with experience mapping LWIs, produced the digitized mapping products. Field work was performed for Phase 1 between May and 3uly 1997. Phase 2 field work was conducted between June 14 and September 16, 1998. Oregon City Local Wetland Iriventory Page -1- June 24, 1999 and Riparian Assessment � This report documents the methods and results of the LWI. In addition, the relative quality of the wetlands was assessed using the Oregon Freshwater Wetland Assessment Methodology (OFWAM; Roth, et al., revised edition, 1996). This information was used to identify significant wetlands within the City's UGB to address Goa15 requirements for wetland protection. Riparian assessments were conducted using the Urban Riparian Inventory and Assessment Guide (Riparian Guide; Pacific Habitat Services, 1998). A brief description of the OFWAM and Riparian Guide processes are provided in Sections 2.3 and 2.4 of this document, and the summary sheets for each wetland are included in Append� A and Appendix B, respectively. Methods used to conduct the study are found in section 2.0; project area characteristics are described in section 3.0; wetland findings are reported in section 4.0; and riparian fmdings are reported in section 5.0. Section 6.0 includes a surnmary of the project, an.d'section 7.0 lists a11 referenc�s used. Appendix A contains data sheets, OFWAM assessment worksheets, and results organized by watershed and wetland code; Appendix B contains riparian assessment worksheets and resul.ts; Appendix C contains a complete OFWAM guide; and Appendix D contains the Riparian Guide in its entirety. The wetland and riparian inventory section maps are attached separately to this report. 2.0 SOURCE MATERIALS AND METHODS 2.1 Source Materials Available information and data were compiled and reviewed before field work was conducted. For example, soil mapping information was compiled from da.ta. available from the U.S. Department of Agriculture (USDA) Soil Conserva#ion Service (SCS, now known as the Natural Resource Conservation Service [NRCS]) county soils survey. U.S. Geological Survey (L7SGS) 7.5-minute topographic quadrangles, USFWS NWI maps, flood insurance rate maps from the U.S. Department of Housing and Urban Development Federal Insurance Administration (FIRM), City zoning maps, and tax assessor maps also were consulted. A digitized base map of the study area was obtained, which included layexs for tax lot lines, street names, rights-of-way, and section boundaries. A series of recent, spring, color, aerial photographs was obtained for the study area at the scale of the base map. Other source materials included: Oregon Rivers Information System (ORIS) fish presence data base; Oregon Department of Environmental Quality (DEQ) 303(d) report {1998}; Classification and Catalog of Native Wetland Plant Communities in Oregon (John Christy, 1993); 1982 City of Oregon City Inventory of Water Resources; and a current data. search from the Oregon Nat�.u Heritage Program (OHNP). This information was used to develop a preliminary indication of the location and possible quality of wetlands, facilitate on-site gathering of data, and complete the assessments. The City, with assistance from SHAPIRO, identified properties likely to contain wetlands. The owners of the identified properties then were sent an access permission letter. Properties to which access was granted were located on the aerial photograph and later noted on inventory maps. Oregon City Local Weticmd Irtventory Page -2- � June 24, 1999 and Riparian Assessment 2.2 Local Wetlands Inventory 2.2.1 Overview of the Local Wetlands Inventory The 1989 Oregon State Legislature authorized the DSL to develop a sta.tewide wetlands inventory suitable for planning and regulatory purposes. Pursuant to ORS 196.674, in 1994 the DSL established LWI standards and guidelines, which are located in OAR 141-86-180 through 141-86-240. The purpose of an LWI is to locate, map, and classify wetlands by type (such as forested wetlands) over a relatively large geographic area. In accordance with LWI standards, the approximate boundaries of all wetlands at least 0.5 acre in size are identified in the inventory. No wetland boundaries were staked or flagged by SHAPIRO for this study. This LWI does include wetland delineations approved by the DSL and COE. These wetland delineations were confirmed within the last ten years, but no later than the end of the field collection period. 2.2.2 Overview of Local Wetlands Inventory Methods A LWI is conducted using color or color infrared, aerial pi�otographs taken within five years of the inventory initiation and at a minimum scale of 1" = 800' (1:9600). In general, wetlands are located using aerial photographs. Then site visits are conducted (on-site) option, as described in the LWI standards and guidelines. In cases in which property access is denied, wetlands can be mapped off the site using other i.nformation, such as topographic maps and aerial photographs, to aid in locating wetlands. The product of an LWI is a parcel-based map showing the approximate location of wetlands at a minimum scale of 1" = 800'. The parcel-based map allows the property owner, local jurisdiction, and DSL to know which tax lots may contain wetlands. 2.2.3 On-site Wetland Determination Where property access permission had been granted, on-site wetland deternunations were made using the Corps of Engineers Wetlands Delineation Manual, Technical Report Y-87-1 (Manual; Environmental Laboratory, 1987): The COE and DSL recognize the use of the 1987 Manual for delineation of wetlands. The Manual provides technical criteria, field indicators, and recommended procedures to be used in determining whether an area is a jurisdictional wetland, and the location of the wetland boundaries. The Manual requires that three technical criteria be met in undisturbed situations before areas can be considered wetland u�der federal or state jurisdiction. These criteria axe the presence of hydric soils, hydrophytic vegetation, and wetland hydrology under normal circumstances. If one of these criteria cannot be determined because of disturbance caused by recent natural events or human activities, an alternative method must be used in making wetland determinations. Observations of soils, vegetation, and hydrology were made using a modification of the Manual's "Routine �Jnsite" method. Data sites were selected to provide a valid representation of site conditions. Data were collected from representa.tive sampling locations to justify the location of the wetland boundary. However, additional sample sites were investigated between these data points to verify changes in the three parameters, further characterize the wetland, and refine the wetland boundary. Oregon Ciry Local Wetland Iriventory Page -3- June 24, 1999 and Riparian Assessment Hydrologic Assessment The Manual defines wetland hydrology as saturation within a major portion of the root zone (usually above 12 inches), typically for at least 12.5% of the growing season. The growing season for any given site or location is deterrruned from SCS or NRCS data and information. The growing season is defined as the frost-free period recorded at the nearest recording staxion five years out of ten. Wetland hydrology field indicators were recorded for each excavated soil pit. Data typically recorded include depth of inundation, water table, and soil saturation. Primary indicators, such as sediment deposits, watermarks, drift lines, and drainage patterns, or secondary indicators, such as oxidized rhizospheres (root zones), also were recorded. Soils Assessment Hydric soils are those that have formed exclusively under wet conditions (soils that characteristically have high water ta.bles, are ponded or frequently flooded, or are otherwise saturated for e�rtended periods during the growing season}. The possible location of hydric areas on the site was obtained from the SCS or NRCS county soil survey. Soil pits were excavated to a depth of 18 inches or more in selected locations in relation to identified potential wetland areas. Soil profiles were examined for hydric soil indicators. Soil characteristics (matrix color, mottling, texture, and other features) were recorded. Vegetation Assessment Hydrophytic vegetation consists of those plant species that have adapted to growing in substrates that are periodically deficient of oaygen because of saturated soil conditions. Species lists of commoniy encountered plants and their status have been prepared for all regions of the country by the USFWS (1988 with 1993 supplement). The status of a particular plant is the probability of that plant occurring in a wetland. Five basic groups of vegetation are recognized in the USFWS list based on their frequency of occurrence in wetlands (Reed, 1988, 1994). These categories, referred to as the "wetland indicator status" (from the wettest to driest habitats), are as follows: obligate wetland (OBL) plants; facultative wetland (FACV� plants; facultative (FAC) plants; facultative upland (FACU) plants; and obligate upland (LJPL) plants. Refer to data sheets in Appendix B for these categories. Many plants are found in transitional areas between wetlands and uplands. These areas are usually characterized by flat to gradually sloping tenain where the species composition may not reflect true wetland boundaries. In such areas, a species with a status of FACU may extend into the wetland areas, just as FACW species may be present in upland areas. A visual percent-cover estimate of the dominant species of the plant community was performed for key sample sites. A 30-foot-radius azea was investigated for dominant tree and shrub species, and a 10-foot-radius area for doxninant herbaceous species, using soil pit locations as a center of reference. Dominance of plant species was determined by estimating their percent areal cover per stratum (herbaceous, shrubs, waody vines, and trees). Species from each stra.tum were listed together in descending order of percent cover. A determination as to predominance of hydrophytic vegetation was made using the 50-20 technique. The most abundant plant species Oregon City Local Wetland Irtventory Page -4- June 24, 1999 and Riparian Assessment (when ranked in descending order of abundance and cumulatively totaled) that, when totaled, immediately exceed 50% cover, plus any species comprising more than 20% cover, represent the dominant species (Federal Interagency Committee for Wetland Delineation, 1989). If more than 50% of the dominant species included by the above criteria are FAC or wetter, the vegetation community is considered hydrophytic. FAC- species are excluded and axe considered non- hydrophytic vegetation. The "-" indicates plant species that prefer slightly drier conditions on average. A"+" indicates plant species that prefer slightly wetter conditions on average. 2.2.4 Off-site Determination No on-site sampling could be conducted where property access permission had been denied or not explicitly approved. Therefore, off: site determinations were made on the basis of aerial photograph inspection, all available mapped attributes (e.g., SCS soil surveys and NWI maps, confirmed determinations and delineations), and, where available, a reconnaissance from nearby public or approved vantage points. Observations from vantage points included documentation of dominant vegetative communities (forested, scrub/shrub, or emergent) and water regimes (such as ponded areas and obviously wet meadows). Approximate wetland boundaries were drawn on aerial photographs. Boundaries deternuned in this way may not be sufficiently accurate for state and federal jurisdictional determinations because of the absence of actual on-site data. In addition, where views into properties from vantage points were not possible or otherwise restricted, and where aerial photographic and mapped information was inconclusive, some wetland areas may have been missed and were not inventoried. 2.2.5 Classification of Wetlands The Cowardin classification system was used to classify the types of wetlands inventoried (Cowardin, et al. 1979). The Cowardin system classifies wetlands according to general systems, structure, vegetation types, water regime, and other modifiers. For example, wetlands within the Oregon City study area are of the palustrine and riverine classes. Palusirine combines vegetated freshwater wetlands (traditionally called marshes, swamps, bogs, fens, and wet pra.iries) and small, shallow, permanent, or intermittent water bodies called ponds that are less than 2 meters (6.6 feet) deep. This classification applies to emergent, scrub/shrub, and forested wetland areas. Wetlands dominated by grasses and other herbaceous plants are classified as PEM, Palustrine Emergent. Wetlands dominated by woody species less than 30 feet high are classified as PSS, Palustrine Scrub/Shrub. A site dominated by woody species over 30 feet high is classed as PFO, Palustrine Forested. The riverine classification is composed of wetland and aquatic habitats contained within a stream channel that is not dominated by vegetation. The NWI inventory maps also use the Cowardin classification system for mapped wetland habitats. 2.2.6 Data Compilation and Interpretation Data were recorded in the field and subsequently transferred to computerized standard wetland delineation data sheets. Sampling site locations were recorded on the aerial photographs. The approximate boundaries of wetlands and streams, and location of sample sites were drafted on the aerial photograph in the field. These boundaries subsequently were digitized onto the AutoCAD maps. All wetlands and streams received a unique code to aid in their identification. Oregon City Local Wetland Ircventory Page -5- June 24, 1999 and Riparian Assessment The code was based on the drainage basin the wetland or stream was located in and their number within each basin. In general, parts of wetlands received separate codes where major roads or distinct breaks in wetland character occurred. Some wetlands were grouped and coded as one unit where they were adjacent, hydrologically linked, or similar in character, thus functioning as a unit. Wetland delineation boundaries confirmed by the DSL were digitized from photocopies of maps in reports submitted to the DSL. In addition, mitigation areas were drawn on the maps, if their locations were known. 2.2.7 Classification of Streams Streams and drainage ditches lacking positive field indicators for wetland determination have been mapped and categorized separately from wetlands in the inventory. Typically these water resources consist of natural and modified stream channels bordered by non-wetland vegetation. These streams are often located in steeply sloped forested canyons. Excavated drainage ditches that fail to meet the criteria for wetland vegetation, soils, and hydrology have also been inventoried as streams rather than wetlands. Summary sheets describing mapped non-wetland streams, follow the wetland mapping code sequence throughout the report. 2.2.8 Confirmation of LWI A draft set of maps and report is provided to the DSL for its confirmation and assessment. Once the DSL has reviewed the documents, SHAPIRO will review the comments and make modifications to the draft wetland maps and report. The products are then resubmitted for final approval. The status of this report as draft or fmal is indicated on the report cover and maps. 2.3 Wetland Quality Assessment 2.3.1 Overview of the Oregon Freshwater Wetland Assessment Methodology 'The OFWAIVI was developed by an interagency committee to assess the relative quality of a- wetland. The methodology is intended for use by planners, public officials, and community members for planning and educational purposes. Completion of this methodology provides basic information, which is not intended for evaluation of detailed, site-specific impacts on individual wetlands. OFWAM is based on the idea that an undexstanding of the wetland system functions and conditions at local, state, and federal levels is necessary to make management decisions. Recommended uses of OFWAM include collection of basic information about wetlands in an assessment area, creation of a database of functions and conditions and other wetland data, support of decision making and planning within a jurisdiction, and education. OFWAM requires that the same functions and conditions be evalua.ted for each wetland within a study area. There are, in addition, other considerations noted in the following sections that determine the wetland's overall value. Oregon City Local Wetland Ircventory Page -6- June 24, 1999 and Riparian Assessment • 2.3.2 Application of OFWAM OFWAM assessments were partially completed during field work using data gathered in the field. Other source materials were used to complete the assessments. The methodology provides qualita.tive information on the relative value of wetlands based on a series of questions related to wetland functions. The following functions are assessed: wildlife habitat, fish habitat, water quality, hydrologic control, sensitivity to impact, enhancement potentiai, education, recreation, and aesthetic quality. Each function is assessed by criteria that give an indication of whether a wetland function is (1) intact, (2) affected or degraded, or (3) lost or not present. OFWAM is designed to be open-ended; therefore, other functions and conditions may be added later, or some may be dropped if not important to the user. The OFWAM results and a summary of the functions and conditions for each wetland axe included in Appendix B. Additional details about assessing the functions and conditions are provided in Appendix D. 2.3.3 Wetlands of Special Interest for Protection A subset of questions within OFWAM provides a method to assess whether any wetlands within the study area should be considered Wetlands of Special Interest for Protection (WSIP). WSIP assesses whether the wetland is currently in a management plan, is protected by regulatory rules or statutes, or is uncommon in Oregon, The presence of rare, threatened, or sensitive species withixi an area makes the wetland a potential WSIP. An affirxnative answer to any one of these questions also will place the wetland into a category for protection. This information could be used in management decisions for a site. The use of OFWAM and WSIP screening questions will assist in an overall evaluation of the wetlands in the assessment area. Many of these WSIP questions are repeated in the locally significant criteria questionnaire (see next section), so the results were combined in one table (see Section 4.3). 2.3.4 Locally Sign�cant Wetland Assessment The term "significant wetlands" has meaning in the context of Statewide Planning Goa15. Under this Goa1, local governments are instructed to identify their significant resources, including wetlands, so those resources serving significant functions in the local community are given proper consideration in planning decisions. The DSL esta.blished a technical advisory committee to develop the locally significant wet�ands (LSV� criteria. The DSL adopted the Administrative Rules for ldentifying Significant Wetlands in January 1997 (141-86-300 through 141-86-350). The criteria rely heavily on the results of OFWAM. Only jurisdictional wetlands are assessed with the criteria. Locally Significant Wetland Criteria: A wetland is considered significant if it meets one or more of the following criteria: ' Wetlands tha.t are given the highest rank for � of the four ecological functions addressed by OFWAM or equivalent methodology (see Appendix D for more details on the ranking): Oregon City Local Weticmd Irrventory Page -7- June 24, 1999 and Riparian Assessment ' wildlife habita.t, ' fish habita.t, ' water quality, or ' hydrologic control. ' Wetlands that (1) are rated either in the highest or second highest category for water quality (in OFWAM or equivalent) AND that (2) border a water quality limited stream, as listed by the DEQ. Dedicated stormwater detention swales are not included. ' Wetlands that contain one or more uncommon wetland plant community, including those listed in the OHNP's Classification and Catalog of Native Wetland Plant Communities in Oregon as Gl-G3 and Sl-S3. ' Wetlands inhabited by any species listed by the federal or state government as a sensitive, threatened, or endangered in Oregon (unless consultation with an appropriate agency deems the site not important for the maintenance of the species). ' A wetland that is a dedicated or proposed Registered Natural Area or Area of Critical Environmental Concern, State Natural Heritage Conservation Area, Federal Research Natural Area, or Land Trust. , ' Wetlands specifically protected as wetland resources in a recognized federal, sta.te, or local management plan, (e.g., for park, refuge, or scenic river). ' Wetlands that rate in the highest category for fish habitat in OFWAM and are located adjacent to a str�eam segment that is mapped by the Oregon Department of Fish and Wildlife (ODFV� as habitat for "indigenous anadromous salmonids." The final two criteria are at the discretion of the local government, but have direct connections to OFWAM results: ' Optional Criterion (at discretion of local government): The wetland represents a locally unique plant community. Wetland is or contains the only representative within the UGB of a particular native plant communiiy (listed in the OHNP's Class�cation and Catalog ofNative Wetland Plant Communities in Oregon). To be identified as a LSW, such a wetland also must score the highest or second highest rank for � of the four ecological functions addressed by OFWAM or equivalent methodology. ' Optional Criterion (at discretion of local government): The wetland rates at the highest rank for education potential, and there is documented use for educational purposes by a school or organization. Oregon City Local Wetland Irrventory Page -8- June 24, 1999 and Riparian Assessment The City will be required to prepare local wetland protection ordinances to apply to locally significant wetlands. Additional wetlands may be protected based on other information, such as the results of the WSIP. Any wetlands not protected by local ordinances may still be under the jurisdiction of DSL and COE. 2.4 Riparian Assessment 2.4.1 Overview of Riparian Assessment In accordance with Goal S, a riparian inventory and assessment was performed for limited areas within Oregon City's UGB. Goa15 requires local governments to inventory and protect riparian corridors. Riparian areas are zones of transition between aquatic ecosystems and terresfirial ecosystems. Goa15 includes definitions that estabiish a riparian area adj acent to every river, lake, or stream, including intermittent slreams with a defined channel. Human-made irrigation or drainage ditches are specifically excluded. Riparian areas can enhance water quality, reduce erosion, moderate water temperatures and flood flows, and provide important fish and wildlife habitat. Riparian areas are particularly important for anadromous salmonids, which rely on cold, clean water and the ha.bitax created by large woody debris. Local governments have two options that can be implemented in the protection of riparian areas. One option is to inventory and assess all riparian areas as described above, establishing the width of the riparian corridor on the basis of riparian vegetation. The inventoried sites are then analyzed to determine their significance, and ordinances are implemented to provide appropriate protection. The other option is to implement the "safe harbors" provision. Under this plan, only riparian areas adjacent to fish-beari.ng water resources are included for protection, and their width is based on the average stream flow of the water resource. Loca1 governments may use either of these options, or some combination of them, to manage their riparian resources. The riparian inventory and assessment was conducted using the methods contained in the Riparian Guide (a copy of which is found in Appendix E). The Riparian Guide is a rapid inventory and assessment method for defining the location and quality of riparian areas. It is intended as a tool to provide consistent riparian inventory results. This document provides guidance for determin;ng the width and length of riparian areas, and for assessing their water quality, flood management, thermal regulation, and wildlife habitat functions 2.4.2 Methodology of the Riparian Guide The Riparian Guide includes a field inventory component, during which i.nformation is gathered on the width and other physical characteristics of the riparian areas. Riparian areas are assessed as left and right reaches facing downstream. Reaches of the riparian area are split where the character of the riparian area changes. The potential tree height (PTI� of the dominant tree species in the riparian area determines the width of the riparian areas assessed. Based on these field observations, the following functions ofthe riparian area are assessed: (1) Water quality, (2) Flood Management, (3) Thermal Regulation, and (4) Wildlife Habita.t. Oregon City Loca1 Wetland Iriventory Page -9- June 24, 1999 and Riparian Assessment In general, a riparian area receives a higher ranking when the following criteria are met: ' average slope in the riparian azea is less than 10%; ' dominant vegetation cover in the riparian area is woody vegetation (trees, shrubs, vines) greater than 1 meter (3.2 feet) high; ' dominant vegetation at the top of the bank or edge of the water resource is woody vegetation greater than 1 meter (3.2 feet) high; ' e�ent of impervious surface is less than 10%; ' the NRCS ranks the water erosion hazard of the dominant soil unit as low, slight, or moderate; ' aspect or orientation of the riparian area allows shading of the water resource at midda.y during the summer; ' flood prone areas (adjacent flat areas, depressions, swales, FEMA mapped 100-yeaz floodplain) are present beyond the top of the bank or edge of the water resource; ' woody vegetation (trees, shrubs, vines) greater than 1 meter (3.2 feet) high are dominant in the flood prone area; ` large woody debris is present within the riparian area; ' stream or water resource is not constricted by human-made features (e.g., channelization, riprap, concrete wall, etc.); ' water resource is bordered by a vegeta.ted riparian area at least 30 feet wide; ' more than two vegeta.tion layers are present (e.g., canopy, mid-story; groundcover) ' woody vegetation overhangs the edge of the water; ' surface water is present throughout year; ' more than one type of water resource (stream, wefland, lake/pond) is within or immediately adjacent to the riparian reach; ' degree of development or human-caused disturbance (e.g., buildings, i.mpervious surfaces, lawns, agriculture, trash) in the riparian area is less than 25%. Where these factors are present or developing, the riparian area provides for water quality, flood management, thermal regulation of the water resource, and wildlife habitat. 2.5 Cartographic Products Wetland boundaries were drawn on aeriat photographs. Aeriai photographs can ha.ve distortion at the edges, s� digitized boundaries were adjusted. The inventory was mapped at a scale Iarger than the scale required in the LWI rules to allow for more ciarity. However, at the map scale of 1" _ 600' (1:4840), the width of a wetland boundary line is approximately 6 feet. Wetland field staff reviewed early draft maps and made corrections where necessary to increase the accuracy of the maps. Sample sites were identified within properties to which access was permitted. Ditches and other narrow linear features loaated on the edge of a property were occasionally drawn slightly to the side of the property line for. gra.phic clazity. Each section map includes a small portion of the adjoi.ning sections. The overlap allows for ease in viewing a we�land that may cross section boundaries. Using AutoCAD, a line was drawn paralleling the edge of the stream to show the width of the potential riparian area. Oregon City Local Wetland Irrventory Page -10- June 24, 1999 and Riparian Assessment 3.0 PROJECT AREA CHARACTERISTICS 3.1 Background Information Available information and data, were compiled and reviewed before field work was conducted. Soil mapping information was compiled from data available in the SCS Soil Survey of Clackamas County Area, Oregon. Preliminary wetland information was obtained from Canby, Gladstone, and Oregon City, Oregon NWI maps. Local knowledge about water resources was incorporated into the study by giving reference to the Inventory of Water Resources (the "Yellow Dot" map) prepared by the City in 1982. Floodplain information was obtained from Oregon City and Clackamas County FEMA-FIRM 100-year floodplain maps (LT.S. Dept. of Housing and Urban Development, 1979). Also consulted were the Canby, Glads'tone, and Oregon City, Oregon USGS 7.5-minute topographic quadrangles; detailed topography maps from the City of Oregon City (1997, 1"= 400', 2-foot contours); Oregon City's Surface Water Management basin map (1997); and City zoning maps. Other source materials included: the Oregon Rivers Information System (ORIS; Baker and Forsberg, 1994) fish presence data base; Oregon's 1998 Section 303(d) List of Water Quality Limited Waterbodies (Oregon Department of Environmental Quality [DEQ], 1998); Classification and Catalog ofNative Wetland Plant Communities in Oregon (Christy, 1993); and a current data search from the ONHP. This information was used to develop a preliminary indication of the location of wetlands, identify drainageways, highlight low-lying areas, facilita.te on-site gathering of data, and complete the assessments. Oregon City provided a digitized base map of the study area. This map included layers for tax lot lines, street names, right-of-ways, and section boundaries. The project area base map was then plotted at a scale of 1" = 400' onto 18 18" x 24" sheets. Each sheet covers a section and small portions of surrounding sections, and includes an index map. Five color, aerial photographs dated June 16, 1996 were obtained from Northern Light Studio, Inc. for the study area (approximately 24" x 36") at an approximate scale of 1" = 400' to match the scale of the base map. These aerial photographs were covered with clear acetate (permanently registered) to protect them during field use and as a surface for drafting wetland boundaries and sample sites. The City, with assistance from SHAPIRO, identified propertie� likely to contain wetlands. The owners of the identified properties were sent an access permission letter. The boundaries of properties to which access was granted were identified on the aerial photograph and base map: 3.2 Setting The City of Oregon City is located on the eastern edge of the Willamette Va11ey at the base of the Cascade Range foothills in Clackamas County, Oregon (Figure 2). The confluence of the Clackamas River with the Willamette River is at the northwestern corner of the City. These rivers form the City's western and northern boundaries. The main ground transportation corridors are Oregon CityLocal Wetlandlriventory Page -11- � June 24, 1999 and Riparian Assessment Interstate 205 across the northern portion of the City; Sta.te Highway 99 East along the banlc af the Willamette River, Highway 213 extending south, and Redland Road, which heads east from the City. The boundary of the wetland inventory area corresponds with the City's UGB (Figures 1 and 2). Starting in the northem portion of the City where the I-205 bridge crosses over the Clackamas River, the UGB heads east, then south to the vicinity of Stolz and Holcomb Roads. It then tums southwest to Anchor Way and Division Street, then south toward Beavercreek Road. North of Beavercreek Road, the UGB turns east, with a northern extension to include the Country Village development. It then turns south to Beavercreek Road and Timbersky Road, the southeastern corner of the UGB. The boundary then turns west to South End Road and Impala Lane, north then east to Lawton Road and Amanda Court, then northwest to the Willarnette River. It then follows the Willamette River northeast to the confluence with the Clackamas River, and returns to the starting point. 3.3 Topography and Geology Oregon City's wetland inventary area includes dramatic topagraphic variation (Figure 2). The elevation at the confluence of the Willamette and Clackamas Rivers is approximately 10 feet National Geodetic Vertical Datum (NGVD, 1929). Bluffs along the rivers rise steeply to a broad, gently rolling terrace at about 450 feet NGVD. This terrace is cut by steep-walled, high- gradient drainages formed by Abernethy Creek in the center of the inventory area, Beaver Creek south of the inventory area, and their tributaries. Near-surface geology of the Oregon City area is composed of Miocene Columbia River Basalt and Pliocene Boring Lava with more recent fluvial deposits from the Quaternary period. 3.4 Hydrology and Drainage Basins 3.4.1 Overview The Oregon City LWI study area is located primarily in the Lower Willamette sub-basin of the Willamette basin (Figure 2). A very small part of the inventory area along the Clackamas River is in the Clackamas sub-basin of the Willamette basin. The Lower Willamette portion of the area is further subdivided into drainage basins for Abernethy Creek through the center of the study area, and Beaver Creek in the southern portion of the inventory area. The xnain stem of Beaver Creek is outside the southern boundary of the siudy area, but tributaries on the northern side of the creek originate in and flow through the southern part of the inventory area. 3.4.2 Natural Drainage Basins Abernethy Creek, a perennial stream, is the lazgest stream within the UGB, and is located i.nside the inventory area from its mouth to Highway 213. In the eastern portion of the inventory area, Abernethy Creek meanders south af UGB in several areas, inciuding its confluence with Newell Creek. Between its mouth and Newell Creek there are two tributaries that join the northern side of Abernethy Creek. The westernmost tributary (Tour Creek) is not mapped by the USGS. The easternmost tributary (Livesay Creek) is mapped by the USGS as an intermittent stream. Livesay Oregon City Local Wetland Irrventory Page -12- June 24, 1999 arrd Riparian Assessment Creek flows in a deep canyon. Three smaller drainage basins without USGS mapped streams form the headwaters of Livesay Creek. Minor intermittent, unnamed tributaries of Abernethy Creek also run in canyons south of the creek on the eastern edge of the UGB at the northern end of the Country Village development area. Newell Creek is a major tributary on the southem side of Abernethy Creek. Most of Newell Creek flows in a deep canyon. The UGB includes only the upper parts of the Newell Creek basin and smaller drainage areas of internuttent tributaries that flow into it. Only about 0.1 mile of Newell Creek is actually mapped by the USGS within the siudy area, northwest of the intersection of Highway 213 and Beavercreek Road. That part of the stream is mapped as perennial. The Newell Creek headwaters are above the mapped part of the stream, at the ponds of the John Innskeep Environmental Learning Center. These ponds currently receive most of their water from the heating and cooling system of a nearby public school. The water is periodically flushed from the system and drai.ns into the ponds. Natural springs also contribute to the water flow. After leaving the ponds, water from Newell Creek flows in a gentle gradient through a series of channels and culverts, eventually daylighting in the northwestem corner of the intersection of Highway 213 and South Beavercreek Road. It plunges down a concrete flume for approximately 50 feet, then cascades down a steep decline of boulders and plunge pools to the edge of the study area. Beaver Creek has four tributaries that drain the southern portion of the inventory area, including Caufield Creek, Mud Creek, and a small tributary known locally as Little Beaver Creek. Caufield Creek is the farthest upstream, and dra.ins the southeastern end of the inventory area. At the time of the inventory, properties in the upper Caufield Creek basin, in the vicinity of Glen Oak Road, were undergoing residential development, and much of the eastern end of the stream was in culverts. The creek channel south of Glen Oak Road has been excavated, and part of it apparently has been realigned as road-side drainage ditches. These ditches collect runoff and groundwater that make up the initial flow for Caufield Creek, which is mapped by the USGS as a perennial stream. An earthen dam south of Highway 213 has created a pond of approxunately 2 acres on Caufield Creek. The northern side of the pond is a moderately steep canyon wall, while the eastern side is adjacent to fill for Highway 213. The southern side has more moderate topography, with low- density residential development. Upon exiting the pond, Caufield Creek flows through a shrub and forested wetland and riparian area to the southern edge of the inventory area. Mud Creek is the ne� tributary downstream (west) of Caufield Creek. Mud Creek is the longest tributary of Beaver Creek and starts as an intermittent drainage east of the intersection of Linn Avenue and Pease Road. The USGS mapped Mud Creek as an intermittent stream within the inventory area. Most of Mud Creek flows in a modified channel or long culverts and is ponded in sma11 ponds in a city park near the center of the drainage and a small pond at the southern edge of the UGB. West of Mud Creek is a sma11, unnamed, internuttent tributary in the area of the intersection of McCord and Leland Roads. The USGS does not map the stream within the study area. Oregon City Local Wetland Inventory Page -13- June 24, 1999 and Riparian Assessment The westernmost tributary of Mud Creek is known locally as Little Seaver Creek. This drainage starts just north of the intersection of Pease and Partlow Roads. The USGS does not map the stream within the study area. T'his stream has natural channels and portions that have been modified. Several smaller tributaries collect and transport groundwater and surface water. 3.4.3 Basin Coding Wetlands and non-wetland strearns identified in the inventory were assigned unique alpha-numeric codes. Each code identifies the drainage basin the wetland or stream is in and coincides with the City's 18 surface water management drainage basins (Figure 3). The City's surface water drainage basins were used at the City's request to provide consistency with esta.blished nota.tion. The surface water management drainage basins and their wetland or stream codes aze listed below as sub-basins of the major na.tural drainage basins within the UGB. The surface water drainage basins as mapped by the City were modified slightly in a few places, where the natural drainage basin extended beyond the mapped boundaries. . For example, for LWI mapping and coding purposes, the southern tip of the Kelly Field surface water management basin is included in the Abemethy Creek Basin, and a portion of the South End basin extends into the Amanda Court surface water management basin. The Clacka.mas basin includes only floodplains of the Clackamas River basin (CL). The Willamette basin includes several basins: Willamette North (no wetlands mapped); Singer Creek (Sn; Tumwater (no weflands mapped); Clinton (no wetlands mapped); Coffee Creek (CO); and Amanda. Court (AC). The Abernethy Creek basin includes: Park Place (PP); Forsythe (FO); Livesay Creek (LI}, Abernethy Creek (AB); John Adams (JA); Newell Creek (NE); and Thimble (1�. The Beaver Creek basin includes: Caufield Creek (CA); Mud Creek (MU); Central Point (CP); and South End (SE). 3.5 Soils 3.5.1 Overview Most of the soils in the Oregon City study area were formed in mixed allu�ium, stratified glaciolacustrine deposits, and colluvium derived mainly fram basalt. Alluvium is unconsolida.ted sediments deposited by streams. Glaciolacustrine refers to sediments derived from glaciers and deposited in lakes. Colluvium is unconsolidated deposits on a slope or at the foot of a cliff, brought there by mass wasting. There are three major soil associations mapped in the study area: the Cloqua.to-Newberg-McBee association (map unit lj, the Aloha-Woodburn association (map unit 4), and the Jory-Saum association (map unit 10). Oregon City Local Wetland Irrventory Page -14- June 24, 1999 and Riparian Assessment The Cloquato-Newberg-McBee association consists of deep, well-drained, somewha.t excessively- drained, and moderately well-cirained soils formed in m�ed alluvium. These soils are found on the floodplain.s of major streams and are subject to flooding. The association is mapped in the northem part of the study azea near the Willamette and Clackamas Rivers, and near Abernethy Creek. It is abouf 35% Cloquato and similar soils (found on floodplains) 20% Newberg and similar soils (found on naturallevees of floodplains), and 15% McBee and similar soils (found in slightly concave positions on fl�odplains). The remaining 30% is compased of Chehalis, Wapato, McBee Variant, and Camas soils. Soils of this unit aze used for cultivated crop production, recreation, wildlife habita.t, and home site development. The main limitation of this association is the hazard of flooding. The Aloha-Woodburn association consists of deep, somewhat poorly-drained, moderately-drained, and moderately well-d�rained soils that formed in stratified glaciolacustrine deposits. These soils are found mainly on broad valley terraces incised by the Willamette River. Sometimes they are found on long, narrow terraces incised by the Clackamas River. The association is mapped generally in the middle zone of the siudy area and along the Willamette River. It is about 40% Aloha and similar soils (found in nearly level and gently sloping areas on tenaces) and about 20% Woodburn and similar soils (found in nearly Ievel to moderately steep, convex positions on broad terraces). Of the remaining 40%, only Amity, Cove, Sa1em, and Wapato soils are found in the study area. The soils of this unit are used for cultivated crops, timber production, wildlife habita.t, and home site development. Their main limita.tions are a seasonal high water table and restricted peimeability. The Jory-Saum association consists of deep, well-drai.ned soils that formed in colluvium derived mainly from basalt and are found mainly on rolling hills. The association is mapped generally in the middle to southern zones of the siudy area. It is about 50% Jory and similar soils, and about 15% Saum and similar soils. Of the remaining 35%, only Barges, Bornstedt, Cottrell, Hardscrabble, and Nekia soils aze found in the study area. Soils in the unit are used for timber production, hay, and pasture. The acidity of the sails, low fertility, and steep slopes are limiting factors to cultivated crop production. Restricted permeability, low soil strength, and steeper slapes are the main limitations to home site development. 3.5.2 Soil Types Forty soil types are mapped within the Oregon City UGB. These soils and their mapping codes are shown in Table 1. Hydric soils and soils with hydric inclusians and wet spots also are intlicated in the tabie. Mapping units are shown in Figure 4. Hydric soils are mapped in only seven scattered areas within a few basins, including: South End, Central Point, Amanda Court, a sma11 area within Newell Creek, along Abernethy Creek, and two areas within the Clackamas floodplain. However, soils with hydric soil inclusions are mapped in much of the study area. �iydric Soil Series Borges silty clay loam, 0 to 8% slopes (7B), is a poorly-drained soil formed in mixed clayey alluvium and found in concave areas on rolling uplands and high terraces. A common prafile has a surface layer of very dark gray and very dark grayish brown silty clay loam about 6 inches thick. The subsoil layer consists of about 6 inches of dark grayish brown silty clay loam. The upper 27 Oregon City Loca1 Wetland Imentory Page -I S- June 24 1999 and Riparian Assessment Table 2.

One stream was mapped in the Abernethy Creek sub-basin, totaling 7.7 acres or 49% of the non-wetland streams mapped in the study. T'he remaining twelve stream segments, mapped in the Caufield Creek, John Adams, Livesay Creek, Mud Creek, Newell Creek, and Singer Creek sub-basins, total 8.0 acres or 51 % of the mapped non-wetland streams. 4.2 Oregon Freshwater Wetland Assessment Methodology Results The results of the OFWAM are suminarized in Table 4. The functional level of each assessed characteristic is shown for each wetland. These functional levels are derived directly from the assessment summary forms. Detailed responses used to generate the summary results are available on the data forms for each wetland, which are provided in Appendix B. This table is useful primarily for obtaining an overview of the current and potential functional status of each wetland. More detailed information (individual OFWAM data sheets) should be consulted before making decisions regarding any wetland.

The soil is classified as fine, miYed, nonacid, mesic Typic Humaquepts. Permeabiliiy is very slow. Cove silty clay loam (25), is a poorly-drained soil with very slow permeability located on floodplains and formed in clayey alluvium. It is classified as fine, montmorillonitic, mesic Vertic Haplaquolls. The surface layer is black silty clay loam about 7 inches thick. The subsoil is about 36 inches thick, and is black and very dark gray silty clay. The substratum is dark grayish brown silty clay to a depth of 60 inches or more. Delena silt loam, 3 to 12% slopes (30C), is a poorly-drained soil formed in silty alluvium and is found on high terraces and rolling uplands. A typical profile consists of a surface layer about 12 inches thick of very dark grayish brown silt loam. The upper layer of the subsoil is clark grayish brown and grayish brown silty clay loam about 13 inches thick. The lower subsoil layer is grayish brown, dark grayish brown, and yellowish red cemented silty clay loam hardpan about 35 inches thick. Depth to the hardpan ranges from 20 to 30 inches. Permeability is moderate to a depth of 25 inches and very slow below this depth. Riverwash, 0 to 3% slopes (73), consists of cobbles, stones, gravel, and sand in nanow, irregular strips along the major strearns and rivers in the study area. The strips are 0 to 10 feet above the water level of the rivers and streams, and range from 20 to 200 yards wide. Riverwash is 40 inches to several feet thick. This material supports little vegeta.tion. Wapato silty clay loam (84), is a poorly-drained soil formed in mixed alluvium and found on floodplains.

The second layer is 8 to 15 inches thick, grayish-brown (10YR5/2) silt loam with a clear boundary. The third layer, 15 to 24 inches thick, is dark grayish-brown (10YR5/2) heavy silt loam with many fine, distinct, dark brown (7.SYR4/2) mottles. 3.6 Vegetation 3.6.1 HistoricalOverview Oregon City is on the eastern edge of the Willamette Va11ey unit of the Interior Valley zone of Western Oregon (Franklin and Dyrness, 1973). This zone is the wannest and driest region west of the Cascade Range because of its position in the rain shadow of the Coast Range. Vegetation in the Willamette Valley has been subject to human manipulation for centuries. Native Americans controlled vegetation on extensive areas of the valley by seasonal buming (Johannessen, 1971). Grazing, farming, logging, and development that accompanied Euroamerican occupation of the area changed the native vegetation connmunities extensively and rapidly. Oregon City Local Wetland Iriventory Page -16- June 24, 1999 and Riparian Assessment Accordi.ng to Franklin and Dyrness, four major vegetation communities probably e�sted in the Willamette Va11ey before Euroamerican occupation: oak woodland, coniferous forest, grassland, and riparian communities. Based on information from Johannessen, grassland was probably not a major community type in the area that is now Oregon City. Remnants of the other three community types still exist in the inventory area and are described in the following section (Section 3.6.2). An important subset of the riparian community type is wetland vegeta.tion. While not addressed specifically by Franklin and Dyrness, it is included in the discussion below because of its significance in the present work. 3.6.2 Vegetation Communities Oak Woodland Oak woodland is dominated by Oregon white oak (Quercus garryana). Other tree species sometimes present are Douglas-fir (Pseudotsuga menziesii) and bigleaf maple (Acer macrophyllum). Oak woodlands in Oregon City are most common on flat terraces. A typical example of oak woodland in Oregon City is on the southeastern corner of the Clackamas Community College campus. Coniferous Forest Douglas-fir is the dominant tree in the coniferous forest community. Grand fir (Abies grandis) and bigleaf maple are common minor constituents of this community. This community is most common in the sloping areas of the UGB. The fir grove in the Newell Creek canyon northwest of the iritersection of Highway 213 and South Beavercreek Road is an example of this vegetation type. Riparian Black cottonwood (Populus balsamifera) and Oregon ash (Fraxinus latifolia) dominate riparian communities. Various willow (Salix) species are common in this association. Riparian woodlands are still found in Oregon City along the major streams and floodplains. Areas along Abernethy Creek support an ash forest. Wetland Wetland areas are associated with most drainages within the inventory area. Vegeta.tion in Oregon City's wetlands is diverse, varying from grasses and other_herbaceous plants to trees. Many of the wetlands in Oregon City are palustrine emergent (PEIV�. A common grass in unmaintained sites is reed canarygrass (Phalaris at undinacea), which is found in and along many of the stream channels and drainage ditches. Broadleaf cattail (Typha latifolia) is also found in these areas, if there is sufficient duration of wet conditions. In Oregon City, the palustrine scrub/shrub (PSS) and forest species (PFO) are often found growing internzingled. Major scrub/shrub species include clustered wild rose (Rosa pisocarpa), Nootka rose (R. nutkana), several willow species, salmonberry (Rubus spectabilis), Douglas' hawthorn Oregon City Local Wetland Irrventory Page -17- June 24, 1999 and Riparian Assessment (Crataegus douglasii), red-osier dogwood (Cornus sericea ssp. sericea [Cornus stolonifera]), Douglas spiraea (Spiraea douglasii) and Pacific ninebark (Physocarpus capitatus). Wetland trees include Oregon ash, black cottonwood, red alder (Alnus rubra) and westem redcedar (Thuja plicata). !�ISi.i1� iI_�►1� �l 1►`I 1] 1►�l3.� 4.1 Wetland Classification and Location 4.1.1 Wetland Types and Classification The USFWS, as part of the NWI program, mapped wetlands in the study area (Figure 5). The NWI maps are generated primarily on the basis of interpretation of small-scale (1" = 4,833' [1:58000]), color infrared aerial photographs. Limited ground reconnaissance is conducted to confirm the interpretations. Table 2 shows the Cowardin classifications of wetlands identified by the NWI in Oregon City. The LWI conducted by SI�3APIR0 identified many wetlands within the Oregon City UGB that were not mapped hy the NWI. Figure 6 shows the location of 50 wetlands mapped in the inventory. A total of 78.2 acres of weflands and streams was mapped within the UGB. Table 3 lists each wetland with its area and wetland classification. Most of the wetlands were identified using the �Routine Onsite method of the 1987 manual. In areas where property access was denied, wetland boundaries were determined from offthe site using aerial photographs, topographic maps, observation from adjacent properties, and other pertinent information (refer to Section 3.3.2). Wetlands inventoried by the LWI are identified as palustrine forested (PFO), palustrine emergent (PEIvn, palustrine scrub/shrub {PSS), palustrine open water (POV�, or riverine (RSB; Table 3). Palustrine forested (PFO) wetland accounts for the majority (40%) of wetland acreage mapped in the inventory. These wetlands are vegeta.ted by Oregon ash and Oregon white oak. Many of these wetlands are associated with streams and may experience some degree of inundation during the winter and early part of the growing season. Palustrine emergent PEM wetlands comprise the second largest category of mapped wetlands (29% of the total). The largest amount of this type of wetland is in the Caufield hasin. Palustrine scrub-shrub (PSS) wetlands are found in seven basins in the inventory area, making up 21 % of the total. The largest amount of this type of wetland is found in the Newell Creek basin. Riverine streambed (RSB) streams are unvegetated channels found in the many streams in wetlands within six of the basins (2% of the total). The largest amount of this kind of wetland is found in the Livesay Creek basin. Palustrine open water (POV� wetlands aze uncommon within the inventory area, but are found in seven of the basins.

Naito Parkway, Suite 302, Portland, Oregon 97209 ProJect Number: 7971165 4.3 Locally Significant Wetlands Of the 50 wetlands mapped in the LWI, 8 are relatively unaltered by development and have fairly good buffers (AB-3, AC-3, AC-4, CA-5, CO-4, LI-5, NE-1, andNE-5). Fourteen weflands are only partially altered by development or have only a partial bufFer (AC-1, AC-2, CA-1, CA-4, CL-1, CL- 2, CL-3, CP-2, LI-2, LI-4, MU-1, MLJ-6, SE-2, and SE-3). The remaining 28 wetlands are modified, developed to the wetland edge, or have a narrow buffer. Thirty individual wetland sites or wetland complexes (64.4 acres) were determined to be locaily significant based on the OFWAM analysis of significance (Table 5; Appendix E). These significant wetlands include wetlands withiri all but two basins (Forsythe and Thimble basins). Many of the significant wetlands rank at the highest level or are important for several funckions. Twenty-six of these wetlands are significant because they provide a high function for hydrologic control in the drainage basin. Their loca�ion in developed areas and floodplains and their ability to absorb floodwaters contribute to their importance for flood control. S� of the significant wetlands are significant because of their potential to provide water quality functions in association with two water quality limited streams, the Willamette and Clackamas Rivers. The DEQ has listed these rivers as water quality limited. Five wetla�ds serve important functions for fish and wildlife. Of these five wetlands, three provide diverse habita.t for wildlife, one has intact fish habitat, and two either contain or are associated with habitat lalown to be used by state or federally listed wildlife or fish species. Three wet�ands are withi.n dedicated natural parks or educational faciiities, and one is known to be a mitigation site. Abernethy Creek (AB1) and the golf course water hazards (TH-1, in Thimble Basin) were not included in the significance analysis. Abernethy Creek is considered to be a jurisdictional water-of- the-state, but not a wetland. The water hazards were excavated from non-hydric soil, are unvegetated, and are likely not jurisdictional wetlands. 5.0 RIPARIAN FINDINGS 5.1 Riparian Assessment Areas The riparian inventory and assessment was conducted adj acent to the mainstem of Abe�nethy Creek and one segment of Newell Creek using the procedures in the Riparian Guide (see section maps). These riparian areas were chosen for several reasons. The streams are the largest in the UGB and contain anadromous fish. The riparian areas adjacent to the streams contain the broadest extent of woody riparian vegetation. These factors will be important in the development of protection strategies for these streams. Other streams within the inven#ary area are nflt fish-bearing and have only partially existing riparian areas; therefore, it was deternuned that applying the Riparian Guide in these areas would be inappropriate. The riparian areas on each side of the streams were divided Oregon City Local Wetland Irrventory Page -20- . June 24, 1999 and Riparian Assessment Table 5.

Significant Wetlands and Wetlands of Special Interest for Protection, continued into reaches based on various characteristics, such as the iype of development (or lack thereo fl adjacent to the stream and the species of tree dominating the area. Each segment or riparian reach was coded as to the side of the stream (looki.ng downstream; right side [R] and left side [L]) and its sequential number, with number 1 being the most upstream. On Abernethy Creek, two reaches were evaluated on both the left and right sides. On Newell Creek, one reach was evaluated on each side. The width of each riparian area reach was determined by the PTH (as listed in the Riparian Guide) of the dominant tree species growing in it. 5.2 Riparian Characterization and Results Only two iree species dominate the inyentoried riparian areas. The species and their PTH are bigleaf maple (90 feet) and Oregon ash (75 feet). Therefore, the assigned widths of the reaches varied from 75 feet to 9q feet, depending on the dorninant tree species. The actual widths of existing riparian areas, which are the vegetated buffers that are not maintained as landscape or agriculture, varied from a minimum of 25 feet on some reaches of Abernethy Creek and to the full width of the riparian area as determined by the PTH on Newell Creek reaches. This broad variation in the width and quality of the riparian reaches (suminarized in Table 6) is not surprising because of the e�rtensive historical alteration of the stream corridors. These widths are reported for informational purposes to assist in writing ordinances addressing riparian buffers. Abernethy Creek The first riparian reach on both the left and right sides of Abemethy Creek is relatively intact. The right reach is 5,280 feet long, while the left reach is 9,000 feet long. The dominant tree on both of these reaches is Oregon ash. The riparian area width as determined by PTH is 75 feet. The width of the e�sting vegetated buffer is estimated to be as great as 800 feet in some areas. Topography in this reach includes floodplains and hillsides that rise steeply from the stream, both on the ieft and right reaches. � The functional assessment results indicate that these reaches are functioning at the highest level for water quality, flood management, thermal regulation, and wildlife habita.t. The second reach on both sides of Abernethy Creek has been affected significantly by development. The right reach.is 4,750 feet long, and the left reach is 1,050 feet long. The dominant tree on the left reach is bigleaf maple, giving a riparian width by PTH of 90 feet. Oregon ash dominates the right side, providing a riparian width by PTH of 75 feet. The existing vegetated buffer is as narrow as 25 feet for most of the length of these reaches. Residential, commercial, and industrial development, roads, and parking lots fill most of the riparian area as determined by PTH. The functional assessment results indicate that these reaches are functioning at the higlaest level for water quality and thermal regulation, and at a medium level for flood management and wildlife habitat.

This 1,600-foot-long segment is in a steep canyon. The dominant tree on both sides of the creek is bigleaf maple, which gives a riparian width of 90 feet as determined by PTH. Other trees in the riparian area and surrounding vegetated buffer include western redcedar and red alder. The vegetated buffer along both the left and right reaches exceeds the PTH, is undeveloped, and retains significant natural characteristics. The functional assessment results indicate that these reaches are functioning at the highest level for water quality, flood management, therxnal regulation, and wildlife habitat. Other Streams Caufield Creek, Coffee Creek, Livesay Creek, Mud Creek, Singer Creek, and other unnamed streams and small tributaries witiun the basins were not assessed using the riparian guide. The stream and riparian conditions were recorded on the wetland or stream summary sheets, and the wetland functions were assessed using OFWAM and the locally significant wetland criteria (Sections 4.2 and 4.3). Many small streams in the level, developed areas have narrow or no riparian buffers. In areas of steep terrain and less development, riparian azeas adjacent to these streams are intact and function.i.ng at the highest IeveL 6.0 SUMMARY Oregon City's Goa15 wetland resource inventory has been completed in compliance with guidance from the DSL that govems LWIs. The resulting maps are more complete and of greater resolution and accuracy than the 1982/1993 wetland inventory (Yellow Dot Map) or NWI maps that were previously used by the City to determine the location of possible wetlands. The inventory is a tool that can be used by the City to make informed planning decisions. Fifty individual wetlands or wetland systems, totaling 78.2 aeres, were identified by the LWI. The largest single mapped wetland complex is 21.1 acres. Wetlands inventoried are palustrine forested (PFO), palustrine emergent (PElv�, palustrine scrub/shrub (PSS), palustrine open water (POV�, and riverine (RSB). The majority (40%) of wetland acreage mapped in the inventory is PFO wetland. Small amounts of these wetlands are located in all but four of the basins. Many of these wetlands are associated with stxeams, and may experience some degree of inundation during the winter and early part of the growing season. PEM wetlands comprise the second largest category of mapped wetlands (29% of the total). The largest amount of these wetlands is in the Caufield basin. These wetlands are located in a11 but two of the basins. Thirty wetlands (64.4 acres) were determined to be locally significant. These sigruficant wetlands include wetlands within a11 but two basins (Forsythe and Thimble). Twenty-s� of these wetlands are significant because they provide a high function for hydrologic control witivn the drainage $ Oregon City Local Wetland Iriventory Page -22- June 24, 1999 and Riparian Assessment basin. In addition to hydrologic control, six of the significant wetlands are significant also because of their water quality functions. Six wetlands provide diverse habitat for wildlife, have intact fish habitat, ar are known to have state or federally listed wildlife species. Four wetlands are dedicated as parks or mitigation sites. The riparian comdor assessment along Abernethy Creek resulted in a determination of two reaches on both the left and right sides, the longest being appro�mately 9,000 feet long. The width of each reach was determined by existing vegetation, and varied from 75 to 90 feet. In the lower reaches, actual riparian vegeta.tion and function were almost completely gone. The upper reaches contain significant vegetation, natural value, and are functioning highly. On Newell Creek, one 1,600 foot reach was evaluated on each side of one segment of the stream. The riparian area is intact, is functioning at its highest level, and was detern�ined by existing vegetation to be 90 feet wide. Many of the wetlands, streams, and riparian areas within Oregon City's UGB have been affected significantly by development, whether resiclential, commercial, industrial, or agricultural. There are also wetlands that have had minimal impact from development and are functioning at a high ievel. Each of the wetlands, streams, and riparian areas within the study area still sezves important functions associated with fish and wildlife habitat, water quality, hydrologic control, and quality of life.

It has a high diversity of emergent vegetation with a fringe of 20- to 50-foot-tall Oregon ash (Fraxinus latifolia) on the western end. Channeled areas are well interspersed with open water areas. The surface soil has a very high organic matter content. Althaugh the vegetation was too overgrown for visual verification, the wetland is probably drained by a culvert beneath Redfand Road in the southwestern portion of the wetland.

The primary source of water for the wetland is seeps from ttie slopes and surtace runoff. A berm has been constructed on the western border of the wetland, and an ea.st-west berm bisects a portion of the wetland. The wetland outlet is probably a culvert to a wetland to the north, which eventually flows into the Willamette River through a culvert. Vegetative cover in the forestE;d areas is very dense, providing good wildlife habitat. Open areas border the forested areas and are dominatecl by grasses and shrubs, providing foraging areas for a variety of wildlife. The steep, forested slopes to the e�ist provide wildlife access to the wetland area.

The stream flows into a constructed pond area of fess than 0.5 acre, then continues south, east of land that is currently being developed for single-family homes. In some areas, construction grading has removed riparian vegetation, which is causing erosion and increased runoff into the stream. The emergent wetland area appears to have been delineated recently, and may be proposed for development. It is likely that a variety of wildlife species use the stream corridor and associated wetland and open water areas, because of the variety of habitat and the connectivity of forested and open areas adjacent to the stream.

This is a fairly wide, shrubby grassland with abundant reed canarygrass (Phalaris arundinacea). The stream channel is narrow and probably contains water year-round. At the upstream site (PP-2), the stream is 2 to 3 feet across and approximately 10 inches deep. This site is bordered on the northwest by a major highway (OR 213) and on the southeast by Abernethy Road.

Drainage ditch SE- 3a connects by a culvert under South End Rd. to SE-3b. This shallow drainage flows behind a residence southwest of Salmonberry Dr. The drainage here is bordered by a low-gradient wet meadow (SE-3c) that appears likely to flood during high water periods. The drainage has been channelized and manipulated through the residential property using concrete and rock. From the wet meadow, the drainage flows southwest, then makes a 90 degree turn, flowing southeast along another property line. This drainage is linked to another wet meadow (SE-3f, oriented in a northwest to southeast direction) that widens away from the channel to the south. The wet meadow transitions into an Oregon ash (Fraxinus latifolia) wooded wetland (oriented north to south). Another drainage (SE-3 d,e) connects to the woodland from the north. The woodland changes to wet meadow, and back to woodland again at its southern extent. The drainage channel becomes less manipuiated and more natural, flowing in the southern section of the wetland complex.

Basin: Newell Creek Size (acres): 1.3 This stream is in a very steep, narrow canyon oriented generally north-south. Water flows into the wetland through a culvert in the northwestern corner of the intersection of Highway 213 and South Beavercreek Road. The water exits the culvert and flows down a concrete chute for an estimated 40 to 50 feet before entering a �treambed that is composed predominantly of large boulders. 7he tiow in this stream appears to be perennial, based on the quantity of water observed during the inventory field work. However, a major source of water for the stream is the Inskeep Environmental Learning Center wetland system, which receives much of its water intermittently from a pumping system. The stream contains a large quantity of woody debris, and is well shaded by the trees in the canyon. The steepness of the canyon and the rocky nature of the substrate prohibit the growth of emergent wetland vegetation at the water's edge.

SHAP/RO Project Number.� 7971165 � Appendix C : DSL OFWAM Manual APPENDIX C SUMMARY OF OFWAM ASSESSMENT CATEGORIES Wetland functions and characteristics assessed by the Oregon Freshwater Assessment Methodology (OFWAN� are su�runarized below. The results of the assessment are used � to determine the significance of each wetland. For complete assessment information, consult the OFWAM document. Wetland Functions WILDLIFE H.ABITAT: Wetlands provide habitat for many wildlife species. A single wetland often cannot satisfy all requirements� for wildlife use, so its proximity to other bodies of water or upland axeas is important. Buffers and corridors are also essential for this reason, and they reduce human disturban.ce. Many species also have special habita,t requirements. Good water quality is necessary for amphibians and mammals; structural diversity is important for birds; and a combination of open water and grazing areas is important for waterfowl. OFWAM evaluates the habitat diversity for species usually assoc�ated with wetlands, without emphasizing one particular species. Wetlands assessed by OFWAM can provide diverse habitat for wildlife, habitat for some wildlife species, or have a wildlife habita.t function that is lost or not present. FISH HABITAT Wetlands that contribute to habitat for fish include areas with dense overhan.ging vegetation. This vegetation provides shade, cover, and food sources to related waterways and lakes. Wetlands also provide spawning, rearing, and resting opportunities for fish. However, a wetland need not actually contain fish to contribute to fish habitat, because wetlands may perform important functions for fish-bearing waters downstream. OFWAM evalua.tes how a wetland contributes to fish habitat in streams, ponds, or lakes associated with a wetland. The questions are suitable for both warmwater and coldwater fish, and no particular species is emphasized. Wetlands assessed by OFWAM have a fish habita.t function that is intact, impacted or degraded, or lost or not present. WATER QUALITY (pollutant removal): Sediment Trapping: During periods of heavy rainfall, water runofFinay cause erosion and increase solids suspended in receiving surface waters. The excess sediment entering water systems can damage aquatic ecosystems. Sediment accumulation in stream bottoms can smother spawning areas and kill aquatic insect larvae. It also can reduce the storage capacity of downstream water supply reservoirs. Wetlands perform an important function by irapping sediment from waters that pass through them. As water flows through the wetlands, it is slowed by vegetation, and Appendzx C OFWAM Assessment Categories sed.iment settles to the bottom before the water moves farther downstream. As much as 90% of the solids suspended in the water may be removed as the water moves through the wetland, resulting in cleaner water entering rivers, lakes, and estuaries. Nutrient Attenuation: Nitrogen and phosphorus are the two nutrients most often associated with water pollution. They are also main ingredients of fertilizers used on agricultural fields and lawns, and both are found in high concentrations in discharges from sewage treatment plants and livestock operations. Excessive aznounts of nitrogen and phosphorus in lakes and slow-moving streams can cause a1ga1 blooms and subsequent oxygen deficiencies, which may kill fish and reduce water quality. The processes that occur as a result of excess nutrients are combined under the term "eutrophication." Within limits, wetlands can reduce nutrient levels so the effects of eutrophication on downstream areas are prevented or reduced. OFWAM evaluates the potential of a wetland to reduce the impacts of excess nutrients in stormwater runoff on downstream waters. A wetland assessed by OFWAM can have a water quality function that is intact, impacted or degraded, or lost or not present. HYDROLOGIC CONTROL {flood control and water supply): Wetlands function as natural water storage areas during periods of high runoff a.nd stream flooding. At times, they act as flood regulators by holding floodwaters, then slowly releasing them downstream. This temporary storage reduces the amount of water downstream during floods, thereby reducing peak flows. Through this flood storage mechanism, wetlands associated with tributaries of streams or rivers can prevent water from all tributaries reaching the stream or river at the same time (this is called desynchronization). Wetlands also can act as floodwater "brakes." For example, water flowing through riverine wetlands during floods is slowed by trees, shrubs, rushes, and other wetland vegetation. Wetlands acting as brakes can reduce flood peaks, thereby reducing flood damage, bank and bed erosion, and other adverse effects caused by fast-moving water. Wetlands also have long-term water holding abilities. Wetlands may store water for longer periods, sometimes for months. The slow draining of these wetlands to surface water or groundwater as the water level in the wetland recedes may contribute to the maintenance of base flows in streams connected hydrologically to the wetland. OFWAM evaluates the effectiveness of a wetland to reduce downstream flood peaks and store floodwaters. A wetland assessed by OFWAM can have a hydrologic control function that is intact, impacted or degraded, or lost or not present. EDUCATION: Field trips to wetlands are an important part of the educational experience, providing students opporttuiities to learn about ecological principles. OFWAM bases the educational assessment on the accessibility and diversity of the wetlands. Wetiands that provide fish and wildlife habitat and permit access to other naiural features a11ow a broader course of study. Appendix C OFWAM Assessment Categories OFWAM evaluates the suitability of a wetland to provide educational opportunity arzd act as an"outdoor classroom." A wetland assessed by OFWAM can have educational use, potential for educational use, or not be appropriate for educational use. RECREATION: Many recreational activities take place in and around wetlands. Wetlands associated with open bodies of water also may support boating and fishing. Many people simply.enjoy the beauty and sounds of nature and spend time walking in or near wetlands observing plant and animal life. OFWAM evaluates the suitability of a wetland and associated watercourses for non- powered boating, fishing, and similar recreational activities. A wetland assessed by OFWAM can provide, have the potential to provide, not provide, or not be appropriate for recreational opportunities. Wetland Characteristics ENHANCEMENT POTENTIAL: Enhancement potential represents how well a wetland might respond to the mitigation of past environmental impacts. The recovery of a wetland, and in particular its wetland function, depends on the site's hydrology, its soils and substrate, and the presence of environmental buffers surrounding the wetland. OFWAM evaluates the suitability of a degraded wetland for enhancement. A wetland fulfilling this condition does not provide one or more of the functions assessed by OFWAM. A wetland fulfilling this condition, therefore, would be of lower overall quality than a wetland providing such features as wildlife or fish habitat. A wetland assessed by OFWAM can have high, moderate, or little enhancement potential. AESTHETIC OUALITY: Although this is a subjective index, it is included to assess the open space and overall pleasing qualities of wetlands to local residents and users. The assessment assumes the user will be visiting the wetland, not just driving by in a car, bus, ar on a bicycle. Wetlands can be areas of scenic beauty. Most often they are viewed from along a stream, from a canoe, along a nature trail, or from an overlook. � The assessment area may include the entire wetland or only a portion, such as an area clearly visibie from a road or stream. Thus, this assessment can be based on an average of several viewpoints or on one outstanding viewpoint. OFWAM evaluates the visual and aesthetic quality of the wetland. Wetlands can be considered pleasing, moderately pleasing, or not pleasing. SENSITIVITY TO IMPACT: The wetland's ability to provide ecological function depends on its condition. If past environmental impacts have affected its ability to sustain itself, its ability to recover from future impacts is d'uninished. Various factors, such as vegetation type, contribute to a wetland's sensitivity. Forested wetland types, for example, aze considered particularly sensitive, because their vegetation structure is complex and slow to recover once disturbed. Also, a wetland is considered sensitive to impact if the quantity and qtxality of its water supply has been altered or c�egraded, and if Appendzx C OFWAM Assessment Categories the intensity of adjacent land use suggests the impairment is permanent. Under such circumstances, the wetland will have lost some of its natural capacity to reeover form impacts. Small, incremental impacts on sensitive wetlands can oause broader, secondary effects throughout the wetland system. A wetland's resilience depends on whether adverse effects caused by future impacts will be localized or spread throughout the wetland and beyond into other ecosystems. The sensitivity to impact index is an indication of risk to the wetland from future changes in the watershed and land surrounding it. This index evaluates whether an affected or lost wetland function can be restored at a degraded wetland site. It does not evaluate the enhancement potential of changing the vegeta.tion through exotic weed removal, which is considered to be a management issue. Wetland enhancement provides opportunities to connect wetlands and adjacent natural areas, thus creating larger natural systems that provide corridors for animal movement. Appendix C OFWAM Assessment Categories ! � Appendix D DSL Riparian �Vianual . APPENDIX D SLrMMARY OF RIPARIAN GUIDE ASSESSMENT CATEGORIES Riparian characteristics and functions assessed by the Urban Riparian Inventory and Assessment Guide (Riparian Guide) are summarized below. For complete assessment information, consult the Riparian Guide document. Riparian Functions WATER QUALITY: Erosion risk is directly related to slope: The steeper the slope, the greater the risk of erosion. Vegetaxion reduces erosion by stabilizing soil and banks through the binding action of roots. Woody vegetation provides the most effective sta.bilization because of its root mass. Declines in urban water quality can be linked directly to an increase in impervious surfaces. Impervious surfaces increase the frequency and quantity of runoff, contribute pollutants, and reduce natural infiltration provided by soil and vegetation. FLOOD MANAGEMENT: The ability of the riparian area to provide a flood management function depends on its potential to store or detain floodwaters temporarily. Floodwaters detained in the riparian area infiltrate into the soil and are slowly released downstream. Woody vegeta.tion reduces the velocity of floodwaters by providing resistance, which increases detention time in the riparian area, allowing the water to infiltrate into the soil. Both of these factors reduce downstream flooding. Channelization of streams and armoring of banks (e.g., riprap, walls, concrete) increase the velocity of floodwaters. Although channeliza.tion and armoring may reduce local flooding by separating the water resource from its floodplain, these measures often increase the risk of flooding downstream. THERMAL REGULATION: In Oregon, vegetation on the southern side of an east-west- oriented water resource has the highest potential of providing shade in the suminer. The ability of vegetation to provide shade is directly related to the height of the vegetation. In general, tall, woody vegeta.tion provides more shade than herbaceous vegetation. Vegetation overhanging a water resource provides shade, creating microclimates. WILDLIFE HABITAT: A vegetated riparian area increases the quality of wildlife habitat by providing food, cover, and nesting opportunities. Vertical complexity of vegeta.tion increases the variety of niches available to wildlife. In general, tall, woody vegetation provides more food, cover, and nesting habitat for a variety of wildlife than herbaceous vegetation. Overhanging woody vegetation contributes leaves, woody debris, and insects to the water resource. It also shades the water resource and creates microclimates. Laxge woody debris in the riparian area provides cover for a variety of small mammals, birds, amphibians, and insects. It can also be transported to the aquatic system in flood events, where it can enhance in-stream f sh habitat. More than one type of water resource within or immediately adjacent to the riparian reach increases the Appendzx D Riparian Guide Assessment Categories comple�ty and quality of wildlife habitax. Human-caused disturbance/development within the riparian area direct�y affects wildlife use. The proximity of human activities may negatively affect sensitive wildlife species that cannot tolerate noise, light, or traffic.
