Its population has doubled since 2001. As a result of this growth, Happy Valley has increased the amount of land in both its city limits and urban growth boundaries. The City of Happy Valley and Clackamas County Water Environment Services jointly contracted Vigil-Agrimis, Inc. to conduct an LWI for areas currently within the City’s jurisdiction that were not included in the 1997 LWI. Figure 1 shows both the 1997 LWI study area and the study area for the 2007 LWI. It is important to note that not all land within the jurisdiction of the City of Happy Valley is covered by the two inventories. The study area for the 2007 LWI includes uninventoried areas within the 1997 LWI study area, the Rock Creek/Aldridge Road Comprehensive Plan Area and the East Happy Valley Expansion Area. The uninventoried areas are either on the flanks of Mt. Scott or along Mt. Scott Creek and its tributaries. The comprehensive plan and expansion areas extend from the 1997 LWI study area boundary south to Highway 212-224 and east beyond SE 172 Avenue. The 1997 LWI inventoried about 1,480 acres. The area inventoried for this LWI totals about 2,500 acres. Descriptions of the project area in subsequent sections of this report refer to this 2,500 acre area, not the City of Happy Valley as a whole which is about 4,513 acres in size. There is a little overlap between the 1997 LWI study area and that of the 2007 LWI. As a result the area not inventoried by either LWI is approximately 533 acres. Much of this land was developed in the years between the inventories and so was excluded from this LWI study area. Because the 1997 and 2007 LWIs cover different areas, both documents will be used when reviewing environmental permitting requirements. 2 DEFINITIONS 2.1 Corps of Engineers Wetlands Delineation Manual (1987 Manual) The main source document used in this investigation was the Corps of Engineers Wetlands Delineation Manual, Technical Report Y-87-1 (Environmental Laboratory, 1987). This manual is recognized by the Oregon Department of State Lands and by the U.S. Army Corps of Engineers for the determination and delineation of wetlands within Oregon. The accepted wetland definition provided in the Manual and used by the Corps of Engineers in implementing Section 404 of the Clean Water Act and by the Oregon Department of State Lands in administering the Removal/Fill Law is: Those areas that are inundated or saturated by surface and 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. Wetlands generally include swamps, marshes, bogs, and similar areas. (Federal Register, 1982). The Manual provides criteria, indicators, and procedures to be used in determining whether an area is a jurisdictional wetland. It requires that three technical criteria be met concurrently in undisturbed situations before areas can be considered wetland under federal or state jurisdiction. These criteria are hydric soils, hydrophytic vegetation, and wetland hydrology. Happy Valley 2007 LWI Page 2 2.2 Cowardin Classification The Cowardin Classification system (Cowardin et al. 1979) is based largely on vegetative cover. Plant cover or its absence can be reliably interpreted from aerial photographs allowing a basis for tracking changes in the surface area of wetlands over time through the National Wetland Inventory. Cowardin Classifications for freshwater wetlands like those in the Happy Valley area include riverine and palustrine systems. Classes within the palustrine system include forested (PFO), scrub-shrub (PSS) and emergent (PEM). Special modifiers used in this LWI include farmed (f), partially drained/ditched (d) and diked/impounded (h). 2.3 Hydrogeomorphic Classification (HGM) HGM classification of wetlands (Brinson 1993) emphasizes the hydrologic and geomorphic controls on wetlands rather than the structure and species composition of the plant community. The approach places emphasis on the importance of abiotic features of wetlands for such functions as the chemical characteristics of water, habitat maintenance, and water storage and transport. HGM classes for freshwater wetlands include riverine, depressional, flats and slope. Subclasses for Oregon wetlands (Adamus 2001) that might occur in the Happy Valley area include flow- through and impounding for riverine, closed and outflow for depressional and headwater and valley for slope. 2.4 Local Wetlands Inventory The 1989 Oregon state legislature authorized the Department of State Lands (DSL) to develop a statewide wetlands inventory suitable for planning and regulatory purposes. In 1990, pursuant to ORS 196.674 and OARs 141-086-0180 through 0350, DSL adopted guidelines and rules for conducting LWIs within urban growth boundaries. The LWI rules were updated in February 2001. The purpose of an LWI is to survey a fairly large area to locate, classify and map wetlands. An LWI aims to map all wetlands 0.5 acres or larger at an accuracy of approximately 25 feet on a parcel-based map. Accuracy may be less in areas that could not be field verified. An approved LWI will replace the National Wetlands Inventory maps and will be incorporated into the statewide wetlands inventory. The NWI is useful for many resource management and planning purposes but it is not accurate enough for use in parcel-based decision making. 2.5 Geographic Information System (GIS) GIS is a computer-based system that is used to capture, store, retrieve, analyze and display spatial data. It combines layers of information about a place to give a more thorough understanding of that place. The layers of information can be combined in different ways depending on ones purpose. Metro is a directly elected regional government that serves the 25 cities in the Portland metropolitan area in Clackamas, Multnomah and Washington counties. It protects open space and parks and plans for land use and transportation among other things. To support these efforts, Metro's Data Resource Center offers subscriptions to Regional Land Information System (RLIS), a compilation of data layers for use with desktop mapping software. This data includes topography, soils, NWI wetlands, floodplains and streams. Happy Valley 2007 LWI Page 3 3 PROJECT METHODOLOGY 3.1 Cartography For this LWI Metro’s Data Resource Center RLIS lite subscription GIS data was augmented with GIS data from Clackamas County. The County supplied data was either more current or higher resolution than that available from RLIS. This data included 2-foot interval contour data derived from 1-foot contours, taxlot boundaries and ownership data, streams and 6-inch resolution georeferenced color aerial photography from 2005. For ease of reading, figures 1 thru 3a use a more simplified RLIS stream layer. The remaining figures use more detailed stream data provided by Clackamas County. The project base map was created in GIS by overlaying the aerial photo with soils, NWI wetlands, streams, water features, watershed boundaries, hill slopes and taxlots. In addition, previously delineated wetland maps of file with DSL and the 1997 LWI map polygons were digitized and added to the base map. The last two sources include few landmarks that could be used to accurately locate the wetland boundaries. Hard copy maps of the study area were printed out at an approximate scale of 1” = 200’ by section. 3.2 Information Processing The approximate wetland boundaries and sample site locations were drawn on the base maps in the field. In addition, a global positioning system (GPS) was used to record sample plot locations and key boundary points. Previously delineated wetlands that were no longer evident were marked off on the maps and were deleted from or modified in the GIS data. Wetlands were assigned a unique code. This code included a two letter watershed abbreviation (the 1997 LWI abbreviations were used) followed by a unique number. Watersheds included in the inventory include: Clackamas River (CR); Kelley Creek (KC) and Mitchell Creek (MC) that are tributaries to Johnson Creek; Mt Scott Creek (MS) and Rock Creek (RC). To avoid confusion between the 1997 LWI polygon identifiers, which began with 1 (e.g. MS-1), and those in the current LWI wetland numbering began at 101 for on-site method wetlands (e.g. MS-101) and at 501 for off-site method wetlands (e.g. MS-501). 3.3 Wetland Identification and Boundary Determination The project area did not include lands inventoried in the 1997 LWI. The project area does include uninventoried areas within the 1997 study area, the Rock Creek/Aldridge Road Comprehensive Plan Area and the East Happy Valley Expansion Area (Figure 1). The uninventoried areas are either on the flanks of Mt. Scott or along Mt. Scott Creek and its tributaries and include small areas within Township 1 south Range 2 east sections 27, 26, 25 and 35. The Rock Creek/Aldridge Road Comprehensive Plan Area covers much of Township 1 south Range 2 east section 36 and Township 2 south Range 2 east sections 1 and 2. The East Happy Valley Expansion Area includes almost all of Township 2 south Range 3 east sections 7 and 6 and Township 1 south Range 3 east sections 30 and 31. The comprehensive plan and expansion areas extend south to Highway 212-224 and east beyond SE 172 Avenue from the 1997 boundary. The area inventoried in the 2007 LWI totals about 2,500 acres. Descriptions of the project area in subsequent sections of this report refer to this 2,500 acre area, not the City of Happy Valley as a whole. 3.3.1 Routine On-Site The on-site method was employed where landowners explicitly granted access to private property. In these cases on-site observations of soil, hydrology and vegetation were made using Happy Valley 2007 LWI Page 4 the routine on-site method in the 1987 Manual. Data was collected in paired plots at representative locations. Additional plots were dug in cases where the boundary was not clearly defined by topography. Data recorded at these plots was recorded on data sheets and included in Appendix B. Based on obvious changes in vegetation, hydrology and topography, approximate wetland boundaries were drawn on air photos. Plot locations were recorded using a Trimble GeoXT GPS. Boundary points were also recorded as needed to facilitate accurate boundary digitizing. 3.3.2 Routine Off-Site The off-site option was used in areas where access was either denied or not explicitly granted to private property. Off-site determinations were made using high resolution aerial photography, 2- foot resolution contour data and reconnaissance from nearby public access vantage points. Observations included documentation of Cowardin and HGM class. Based on observed changes in vegetation, hydrology and topography, approximate wetland boundaries were drawn on air photos. This information was then digitized into GIS. In some cases the wetland determination boundaries on file with DSL could not be field verified. These wetlands were kept in the inventory unless the aerial photography clearly showed a structure or roadway in the wetlands location. 3.4 Wetland Function Assessment The Oregon Freshwater Assessment Methodology, or OFWAM, (DSL 1993) was used to assess the relative quality of identified wetlands. The methodology is intended for use by planners, public officials, and community members for planning and educational purposes. It is not intended for evaluation of site-specific impacts on individual wetlands. OFWAM requires that the same functions and conditions be evaluated for each wetland within a study area. The functions and conditions used in OFWAM include wildlife habitat, fish habitat, water quality, hydrologic control, sensitivity to future impact, enhancement potential, education, recreation and aesthetic quality. Off-site wetlands less than 0.5 acres in size were not assessed unless they were part of a larger wetland complex. Of the functions and conditions used in OFWAM we evaluated water quality, hydrologic control, wildlife habitat, fish habitat, sensitivity to impact and enhancement potential. We did not assess the education, recreation or aesthetic quality of the wetlands because all were on private property and were, therefore, not accessible to the public. 4 PROJECT AREA CHARACTERISTICS 4.1 Setting The City of Happy Valley is located southeast of Portland in Clackamas County, Oregon and is one of the fastest growing cities in the state. The City is east of Interstate 205, north of Highway 212/224, and south and west of SE Foster Road. It has an area of approximately 4,300 acres (6.7 sq. miles) and a population of approximately 9,210 (2007). This LWI is focused on land that was not inventoried in the 1997 LWI. These include uninventoried areas within the 1997 boundary, the Rock Creek/Aldridge Road Comprehensive Plan Area and the East Happy Valley Expansion Area. This area is generally south and east of the area covered by the 1997 LWI. The setting of the project area is diverse. Some areas are surrounded with dense residential development while others are still largely forested or in agricultural use. The least developed locations are on the eastern and southern edges of the project area and on the flanks of Scouter’s Mountain. Happy Valley 2007 LWI Page 5 4.2 Topography The project area is generally associated with the East Buttes and Boring Lava Domes. This area is characterized by gently to steeply sloping uplands and a nearly flat valley floor. Elevations range from approximately 120 feet National Geodetic Vertical Datum (NGVD) at the Rock Creek confluence with the Clackamas River to approximately 950 feet at the top of Scouter’s Mountain. The areas between hills consist of soils and gravels deposited by past flood events, including the Missoula floods. The boring lava flows are up to 100 feet below these alluvial soils. The Troutdale formation is deeper still. It forms an important aquifer in North Clackamas County. It is thought that the buttes and lava domes in this area may provide important recharge for the water table. There are a number of springs in the project area supporting this assertion. Many of the alluvial deposits between the hills have been eroded over time by rivers and streams. The southeastern corner of the project area is traversed by deep river canyons along Rock Creek and its tributaries. 4.3 Hydrology The project area covers portions of a number of watersheds and sub-basins. Rock Creek is the major basin associated with the project area. It flows generally southwest to the Clackamas River. A small part of the Clackamas River basin is included along the southern edge of the project area. The Mt. Scott Creek watershed was the most significant basin in the 1997 LWI, but only a few uninventoried areas in that watershed were included in this LWI. This basin drains much of the urbanized area in the City of Happy Valley to Kellogg Creek and the Willamette River. The northern edge of the project area covers several subbasins of the Johnson Creek watershed including Veterans Creek, Mitchell Creek, and Kelley Creek as well as some unnamed tributaries to Johnson Creek. Springs associated with the Boring Lava Domes are generally not mapped but were considered in this LWI. Though they were not mapped as part of the LWI they may be regulated by state and federal agencies. Many of the low gradient areas in the farmed portions of the Rock Creek watershed have been ditched to promote the drainage of fields for forage and crops. The LWI field assessment was conducted over a two week period between April 4 and 16, 2007. Weather in the month prior to the field work was alternately warmer and cooler than normal. Precipitation at Portland International Airport for March was 3.20 inches, 0.44 inches below normal. Precipitation since January 1 was 9.41 inches, 3.55 inches below normal. The month of April was similar with monthly precipitation at 2.01 inches, 0.63 below normal and annual rainfall at 11.42 inches, 4.18 inches below normal. This data was compared to wetland climate evaluation data from NRCS (Appendix D). Based on this evaluation, hydrology during the LWI field work was about a tenth of an inch below the low end of the normal precipitation range. 4.4 Soils 4.4.1 Overview Twenty three soil types occur across the project area as mapped in the Soil Survey of Clackamas County (Soil Conservation Service, 1983) and shown in Figure 2. Borges silty clay loam (7B), Delena silt loam (30C), and Huberly silt loam (41) are all listed as hydric and have hydrologic classifications of D by the NRCS (formerly SCS, 1989). Hydrologic Soil Group D soils have a very slow infiltration rate when thoroughly wetted. These soils have high clay content and are often associated with a permanently high water table. These soils may have a clay pan or clay layer near the surface or may be regularly flooded. Happy Valley 2007 LWI Page 6 4.4.2 Soil Types Borges silty clay loam (7B) is a deep, poorly drained soil found in concave areas on rolling uplands and high terraces.

It is formed in colluvium derived dominantly from igneous rock. It is classified as mesic Xerochrepts and mesic Haploxerolls. No single profile is typical, but one commonly observed has a surface layer about 8 inches thick that is dark brown silt loam. The upper 7 inches of the subsoil is dark brown gravelly loam, and the lower 33 inches is brown and dark yellowish brown gravelly clay loam. The substratum to a depth of 60 inches or more is brown very cobbly clay loam. 4.5 Vegetation 4.5.1 Overview Since settlement began, vegetation in Happy Valley has been manipulated extensively through logging, agriculture and urbanization. Residential development has increasingly impacted native plant communities and the habitat that they provide. The project area is located in the historic transition between Cascade Mountain conifer forests and the Willamette Valley oak/prairie grasslands. Douglas fir forest and woodland would have dominated much of the area. The lava domes were characterized by closed canopy old growth Douglas fir, grand fir, and bigleaf maple with hazelnut, Pacific dogwood, vine maple, and Pacific yew composing the under story. The valley floors also included western hemlock and western red cedar. Floodplains along or near the Clackamas River had closed hardwood forests, including Oregon ash, cottonwood, alder, maple, and white oak. There were small patches of conifer, including Douglas fir and western red cedar. Today, much of the forest and woodland has been cleared for homes, businesses and agriculture or was historically logged. There are some areas of upland forest on the Buttes and some patches of relatively intact riparian forest still exist along streams and creeks in the area. 4.5.2 Vegetation Communities Mixed Coniferous-Deciduous Forest Douglas fir and big leaf maple are the dominant overstory species in this community which can also include red alder. The understory is relatively sparse. Shrub species include hazelnut, vine maple and Indian plum with Himalayan blackberry in disturbed areas. The herb layer includes sword fern. Deciduous Forest Big leaf maple is the dominant overstory species with red alder in some places. The understory is dense and includes hazelnut, vine maple, red elderberry, oceanspray, snowberry and Indian plum in the shrub layer. Herbaceous plants include sword fern and fringecup. Happy Valley 2007 LWI Page 8 Upland Shrub The upland shrub community is dense and includes alder and cottonwood saplings as well as hawthorn, wild cherry and some hazelnut. Agricultural Grassland There is a considerable amount of agricultural grassland especially in the eastern part of the project area. It includes forage species like fescues, as well as dandelion, clover, and sweet vernal grass. Riparian Communities In steep headwaters the riparian communities are dominated by Western red cedar and alder with salmon berry, spring beauty and lady fern. In lower elevation areas this transitions to Oregon ash, red alder and cottonwood with willow, red-osier dogwood, piggy-back plant and stinging nettle. 4.5.3 Wetland Communities Forested Wetlands The forested wetlands in the project area are largely associated with riparian areas and so include similar species. These are dominated by Oregon ash, red alder, cottonwood and willow. Scrub-Shrub Wetlands Scrub-shrub wetlands include saplings of the forested wetland species as well as hawthorn, red- osier dogwood, honeysuckle and Douglas spiraea. Emergent Wetlands Emergent wetlands were frequently dominated by meadow foxtail, fescue, soft rush and creeping buttercup. In disturbed areas reed canarygrass was also present. 4.5.4 Wetland Indicator Species Trees found in wetland and riparian areas included: red alder (Alnus rubra FAC), Oregon ash (Fraxinus latifolia FACW), black cottonwood (Populus trichocarpa [balsamifera] FAC) and western red cedar (Thuja plicata FAC). Shrub wetland indicators included: willow (Salix species FAC), red-osier dogwood (Cornus stolonifera [sericea] FACW), salmonberry (Rubus spectabilis FAC+), Douglas' spirea (Spiraea douglasii FACW) and black hawthorn (Crataegus douglasii FAC). Emergent wetland species included: meadow foxtail (Alopecurus pratensis FACW), soft rush (Juncus effusus FACW), birdsfoot-trefoil (Lotus corniculatus FAC), common velvetgrass (Holcus lanatus FAC), reed canarygrass (Phalaris arundinacea FACW), stinging nettle (Urtica dioica FAC+) piggy-back plant (Tolmiea menziesii FAC), skunk cabbage (Lysichiton americanum OBL) and American speedwell (Veronica americana OBL). 5 DISCUSSION AND CONCLUSIONS 5.1 U.S. Fish & Wildlife Service NWI & 1997 LWI U.S. Fish & Wildlife Service has mapped the project area as part of the National Wetland Inventory (NWI) program (Figure 3a). Most of the wetlands were associated with creeks, rivers and agricultural ponds. Cowardin classifications included: palustrine emergent persistent saturated / semipermanent / seasonal (PEM1Y), Palustrine scrub shrub broadleaf deciduous saturated / semipermanent / seasonal (PSS1Y), palustrine forested broadleaf deciduous saturated / semipermanent / seasonal (PFO1Y), palustrine open water artificial excavated (POWKZx) and palustrine open water artificial impounded (POWKZh). Happy Valley 2007 LWI Page 9 A majority of the wetlands identified in the 1997 LWI were associated with the banks of Mt. Scott Creek and its tributaries (Figure 3b). These were generally dominated by riparian forest vegetation. The largest wetland was found near the headwaters of Mt. Scott Creek it is dominated by emergent and scrub-shrub vegetation. 5.2 Local Wetlands Inventory Results 5.2.1 Total Wetland Acreage The 2007 Happy Valley LWI project area is approximately 2,500 acres in size. The potentially jurisdictional waters in the project area are primarily associated with saturated areas at the headwaters of Mt. Scott and Kelley Creeks and their tributaries, and with topographic depressions in the Rock Creek valley bottomland and the headwaters of tributary drainages in that system. The wetland summary sheets and plot data sheets are organized alphabetically by watershed and are located in Appendix A and B respectively. About one third of the wetlands were determined using the on-site method and the remainder using the off-site method. The soils most commonly associated with wetlands in the project area are Powell silt loam (70B), Cascade silt loam (13C, 13D) and Huberly silt loam (41). Powell silt loam is a moderately well drained soil with a fragipan layer at 20 to 30 inches. Cascade silt loam and Huberly silt loam are poorly drained with a hardpan layer at about the same depth. 5.2.2 Distribution and Location of Wetlands The inventory identified 61 potentially jurisdictional wetlands totaling 106.37 acres. This area is approximately distributed across the watersheds as follows: 59.70 acres in Rock Creek, 22.05 acres in Kelley Creek, 18.51 acres in Mt. Scott Creek, 4.67 acres in Clackamas River and 1.44 acres in Mitchell Creek. Wetland summary sheets were completed for all wetlands evaluated on-site and for off-site evaluated wetlands greater than half an acre in size. Large wetlands and areas with a number of smaller wetlands are described in the geographic setting sections below. All wetlands are summarized in Tables 1 thru 5. The largest wetlands are in the Kelley Creek, Mt. Scott Creek and Rock Creek watersheds. The general lack of urban development in the Rock and Kelly Creek watersheds is partly responsible for these high numbers. In Mt. Scott Creek watershed the large wetland areas are associated with remnant open spaces in what is now a dense urban fabric. In addition, there are a number of waterways that may be jurisdictional within the project area. Kelley Creek – Rock Creek Headwaters A small area of the headwaters of the Kelley Creek watershed is in the project area. The watershed abuts a headwater drainage of the Rock Creek watershed. Many of the large slope wetlands and slope wetland mosaics in this gradually sloped area extend across these watershed boundaries. Ground and surface water in this are either flows north into Johnson Creek or south into Rock Creek. Wetlands include KC-103, KC-501, KC-502, KC-503, KC-504, KC-505, KC- 506, RC-101, RC-501, RC-502 and RC-503. A majority of these wetlands are open fields with hydrology from precipitation and surface water flow and groundwater. The vegetation is dominated by emergent vegetation like Reed canarygrass (Phalaris arundinacea), meadow foxtail (Alopecurus pratensis), creeping buttercup (Ranunculus repens), birds-foot trefoil (Lotus corniculatus), fescue (Festuca spp.) and soft rush (Juncus effusus). Many of these wetlands are drained by surface channels. In addition to the herbaceous vegetation, there are patches of scrub- shrub and forested wetland dominated by Oregon ash (Fraxinus latifolia). Happy Valley 2007 LWI Page 10 Rock Creek Drainage A large portion of the Rock Creek watershed was included in the project area. The watershed abuts the Clackamas River watershed to which it is a tributary. Many of the wetlands noted in this area were slope wetlands located at the headwaters of small drainages or tributaries. These include RC-101, RC-108, RC-111, RC-115, RC-510, RC-511, and RC-512. Wetland RC-108 is a depressional forested wetland with hydrology from precipitation and surface water flow. The vegetation is dominated by a canopy of Oregon ash (Fraxinus latifolia) with herbs including celery-leaved buttercup (Ranunculus sceleratus) and mannagrass (Glyceria spp.). It is drained by surface channels running to the north. There is a small surface road that separates this wetland from the RC-510 wetland to the south. RC-510 is a slope wetlands dominated by herbaceous vegetation, with scrub-shrub communities in the upper portions. It is drained by surface channels along roads, culverts connect under the roads. Its hydrology is also from groundwater and precipitation. Dominant plant species include meadow foxtail (Alopecurus pratensis) and tall fescue (Festuca arundinacea). Scrub-shrub communities include Nootka rose (Rosa nutkana), willow (Salix spp.) and red-osier dogwood (Cornus sericea). Other wetlands within the watershed are primarily forested slope wetlands associated with springs and seeps, and occasionally depressional wetlands, both along riparian corridors. The vegetation is dominated by woody plants including red alder (Alnus rubra), black cottonwood (Populus trichocarpa [balsamifera]) and western red cedar (Thuja plicata), red-osier dogwood (Cornus sericea), and salmonberry (Rubus spectabilis). Emergent wetland species included stinging nettle (Urtica dioica) piggy-back plant (Tolmiea menziesii), skunk cabbage (Lysichiton americanum) and American speedwell (Veronica americana). Mt. Scott Creek Headwaters The largest wetlands in the Mt. Scott Creek watershed are slope wetlands located at the headwaters of Mt. Scott Creek or its tributaries. The southernmost group includes MS-101, and MS-507. This complex is dominated by scrub shrub vegetation with hydrology from groundwater, precipitation and surface water flow. Water is detained on the site by undersized culverts. The vegetation is dominated by willow (Salix spp.), Nootka rose (Rosa nutkana), red- twigged dogwood (Cornus sericea), reed canarygrass (Phalaris arundinacea) and soft rush (Juncus effusus). Oregon ash (Fraxinus latifolia) is present along the creek. Other large wetlands in the Mt. Scott Creek watershed include MS-504, MS-505 and MS-506 which are an extension of the wetland complex at the Happy Valley Nature Park (MS-14 from the 1997 LWI). These wetlands include scrub shrub and emergent areas. Hydrology is from groundwater, with input from precipitation and sheet flow. Vegetation includes Oregon ash (Fraxinus latifolia), willow (Salix spp.), Nootka rose (Rosa nutkana), red-twigged dogwood (Cornus sericea), Reed canarygrass (Phalaris arundinacea) and soft rush (Juncus effusus). Other Areas A majority of the other potentially jurisdictional waters are associated with small topographic depressions or intermittent and perennial streams. A number of small wetlands are located; on fringes of manmade ponds, in areas where tile drainage systems are failing, and on the downhill sides of impoundments. A small number of wetlands less than a half acre in size were found associated with ground water seeps. These were either on the slopes of Scouter’s Mountain or related to a water impoundment.

Off-site wetlands less than 0.5 acres in size were not assessed unless they were part of a larger wetland complex. Wetlands were assessed together when they were hydrologically connected either by culverts or drainages. Water quality, hydrologic control, wildlife habitat, fish habitat, sensitivity to impact and enhancement potential functions were assessed. Mt. Scott Creek and Rock Creek are both 303(d) listed streams and anadromous fish use the lower reach of Rock Creek which is designated as critical habitat by NOAA fisheries (August 2005). No threatened or endangered species were found to inhabit the wetlands in the project area and we were unable to find any records that wetlands in the area had been identified by federal, state or local agencies or non-profits for protection. A majority of the assessed area is currently pasture, row crops, small farmsteads or wood lots. According to zoning and comprehensive plan designations much of the area will transition to low density residential with Happy Valley 2007 LWI Page 13 some commercial development along major roadways. According to OFWAM no wetlands of special interest for protection were identified in the study area. A majority of the assessed wetlands provided wildlife habitat for some species and had impacted water quality and hydrologic functions. Of the wetlands that provided fish habitat most had impacted habitat functions. Most wetlands were sensitive to future impacts, due in large part to the changes in land use that will result as the area urbanizes, and had moderate potential for enhancement. The watershed characterizations and answer sheets for the functional assessment are located in Appendix C. The wetlands included in each assessment and the findings are included on the wetland summary sheets in Appendix A. 5.4 Locally Significant Wetlands Locally significant wetlands provide habitat, water quality and/or hydrologic benefits at significant levels. The determination of significance is based on the functional assessment results and professional judgment. Locally significant wetlands are identified to help state and local governments and agencies as well as private land owners make informed land use and development decisions. The designation does not provide additional legal protection. Wetlands less than one half acre in size were not evaluated for significance. Fourteen wetlands were determined to be locally significant based on DSL mandatory criteria (Figure 12). This includes wetlands that provided diverse wildlife habitat or had intact fish habitat, water quality or hydrologic control functions. Locally significant wetlands are listed in Table 6. The functional assessment criteria that meet the significance threshold are italicized. Table 6.

Wetlands MS-504, MS-505 and MS-507 provide habitat to diverse species and have intact hydrologic control functions. This is due in part to the fact that they have areas of woody vegetation and controlled outlets. These wetlands are each connected to other large wetlands encompassing most of the wetland area in the Mt. Scott Creek basin. MS-504 is connected to MS-14 and to MS-505. MS-507 and MS-101, which is significant due to intact hydrologic control functions, form the other large wetland area. All of these wetlands are also significant because they are within a ¼ mile of Mt. Scott Creek, a 303(d) listed stream. RC-109 has intact water quality and hydrologic control functions. Both of these functions are enhanced by the fact that this is a depressional wetland with a controlled outlet that is subject to flooding from Rock Creek and is adjacent to developed land. Happy Valley 2007 LWI Page 14 Of the remaining significant wetlands five met one threshold for significance. One, KC-102, provides habitat for diverse species. Three, CR-502, MS-101 and RC-509 have intact hydrologic control functions and RC-108 has intact water quality functions. In addition, five wetlands were deemed significant because they are located within ¼ mile of a 303(d) listed stream – in this case Rock Creek. Of these, RC-510 likely has the greatest potential to effect water quality by filtering out agricultural pollutants and by providing a source of base flow for the stream system in the summer months. As described in OAR 141-086-0350(2)(b), local governments can change significance calls for wetland deemed significant solely based on its proximity to a 303(d) listed stream if that wetland does not provide the water quality improvement needed for the 303(d) list identified parameter(s).
