State Land Board Theodore R. Kulongoski Governor John Morrison, Mayor City of Ashland 20 East Main Street Bill Bradbury Secretary of State Ashland, OR 97520 Randall Edwards State Treasurer Re: Approvai of the City of Ashland Local Wetlands Inventory and Assessment Dear Mayor Morrison: 1 am pleased to notify you that the Department of State Lands (DSL) has approved your Local Wetlands Inventory (LWI) and assessment. We appreciate your planning staff and the wetland consultant working with our staff to ensure that the inventory meets state LWI requirements (OAR 141-86-180 to 240) and the city's needs. The final inventory requirement is for the city to notify property owners with wetlands mapped on their property within 120 days of this approval. Please provide us with a copy of the landowner notification, once completed, indicating the date of notification. Approval by DSL means that the LWI becomes part of the Statewide Wetlands Inventory. The LWI must now be used by the city instead of the National Wetlands Inventory for the Wetland Land Use Notification Process (ORS 227.350). The LWI and functional assessment also form the foundation for your wetland planning under Statewide Planning Goal 5, and the LWI must be adopted by the city per the Goal 5 requirements. Please note when significant wetlands are designated by the city, "non-significant" wetlands may be coded to distinguish them from "significant wetlands," but must not be removed from the approved LWI maps. These wetlands are still subject to state and federal permit requirements. While considerable effort has been made to accurately identify most wetlands within the study area, DSL's approval does not guarantee that all regulated wetlands have been mapped. The mapped wetland boundaries are estimated boundaries, they have not been surveyed, and there are inherent limitations in mapping accuracy. DSL advises persons proposing land alteration on parcels containing mapped wetlands to contact DSL or obtain a wetland boundary delineation by a qualified consultant and submit it to DSL for approval prior to the land alteration. John Morrison, Mayo. March 21, 2007 Page 2 It will be important to annotate your map (and associated database, if any) as new wetland delineations are completed and approved by DSL in order to keep your LWI updated. Future wetland delineation report approvals will be provided to the planning department. We are pleased that the City of Ashland has conducted a thorough wetlands inventory and has made wetland planning a high priority. We look forward to working with you and your staff as you continue on the Goal 5 wetland planning effort. Please feel free to contact Peter Ryan at extension 232, with any questions you may have about the LWI or its use. Sincerely, 012 "'" Louise Solliday Director cc: .

Local Wetlands Inventory Determination Of Locally Significant Wetlands 11 City of Ashland Local Wetlands & Riparian Corridor Inventory & Assessment. July 2005, revised February 2007 Fishman/SWCA Page ii Summary SWCA Environmental Consultants' (Fishman/SWCA), conducted a Local Wetlands Inventory and Assessment and Riparian Corridor Inventory for the City of Ashland. The study area included the Ashland city limits and urban growth boundary. Total study area boundary acreage is 4,959 acres or 7.75 square miles. Fourteen wetland units (WI — W 14) were inventoried and assessed. Eight of these 13 units (W1, W4, W5, W6, W7, WI I , W12 and W13) were not previously mapped in the National Wetlands Inventory or the City's GIS database. Eleven wetland units were associated with streams or were hydrologically connected to a stream via roadside or agricultural drainage ditches. Three (W2, W8 and W9) wetlands did not contain a surface water connection to a stream or other wetland and were therefore determined to be isolated. Total wetland acreage within the study area was calculated to be 28.31 acres. • Locally significant wetlands were identified using the Oregon Freshwater Wetland Assessment Method (OFWAM). Significance was determined based on a wetland's ability to provide high function in one or more of the following categories: wildlife habitat, fish habitat, water quality or hydrologic control, or the wetland's ability to provide medium water quality function if located within 0.25 mile of a DEQ water quality listed stream. Eleven wetland units were determined to be locally significant. The Ashland Demonstration Wetlands (W2) were not designated as locally significant due to their creation for the purpose of wastewater treatment per OAR 141-086-350(1). The Billings Ranch wetland (W3) and the Washington Street wetland (W11) were determined to be non-locally significant. All riparian corridors were inventoried to evaluate general stream characteristics and hydrology, adjacent landform, and vegetation. Significant riparian corridors were determined using the Goal 5 Safe Harbor criteria. Riparian corridors along streams identified by the Oregon Department of Fish and Wildlife as being fish-bearing were determined to be significant according to the Safe Harbor criteria. Significant riparian corridors in the study area include Ashland Creek, Bear Creek, Emigrant Creek, Kitchen Creek, Neil Creek, and Tolman Creek. Further information is included in the accompanying report, and the reader is referred to the appendices for wetland and riparian summary sheets, wetland sample plot data, OFWAM data sheets and other information. J The Portland, Oregon office of SWCA Environmental Consultants was acquired from Fishman Environmental Services in 2004. City of Ashland Local Wetlands & Riparian Corridor Inventory & Assessment, July 2005, revised February 2007 Fishman/SWCA Page l Project Purpose The City of Ashland is required to update their Comprehensive Plan under periodic review for Goal 5 wetland resources. The Goal 5 rule requires the City to inventory its natural resources according to the general inventory process outlined in OAR 660-023- 0030 as well as specific guidelines for wetlands (660-023-0100) and riparian corridors (OAR 660-023-0090). Fishman Environmental Services, a Division of SWCA Environmental Consultants (Fishman/SWCA), conducted a Local Wetlands Inventory (LWI) and Riparian Corridor Inventory (RCI) for the City of Ashland to meet statewide planning Goal S requirements. The LWI was prepared to meet the Department of State Lands (formerly the Division of State Lands) Local Wetlands Inventory Standards and Guidelines (OAR 141-086-0180 through 141-086-0240; effective July 1, 2001). Significant riparian corridors were mapped using the Safe Harbor criteria identified under OAR 660-023-0090(5). The LWI and RCI are required to be submitted to the Oregon Department of State Lands (DSL) and the Department of Land Conservation and Development (DLCD) for review and approval before they can be adopted by the City and used to develop a land use program to conserve and protect significant Goal 5 resources. Background Information Study Area The study area for the Local Wetlands Inventory and Riparian Corridor Inventory includes the City of Ashland city limits and the urban growth boundary. Total study area boundary acreage is 4,959 acres or 7.75 square miles. The study area is located in Township 38 South, Range I East, Sections 31, 32, and 33 and Township 39 South, Range I East, Sections 4, 5, 6, 8, 9, 10, 11, I2, 13, 14, 15, 16, 17, 22, and 23. An index map of the study area is included in Appendix 1. The study area is contained on 12 base maps. Drainage Basin The City of Ashland is located within the Rogue River basin. The study area is contained entirely within the Bear Creek watershed. The study area contains two major drainages: Bear Creek in the north and Ashland Creek in the west. Topography Topography of the study area consists of steeply sloped foothills in the south, a relatively flat central portion that is highly developed, and the Bear Creek floodplain in the north. Streams in the higher elevation areas are confined within steep V-shaped drainages, and streams in lower elevation areas are typically confined within a well-defined stream channel. Therefore, stream-associated wetlands are generally either not present or are limited to a narrow fringe along the stream channel. Fishman/SWCA obtained two-foot contours of the study area from the City of Ashland. Two-foot contours were not available for the northwest portion of the study area in Sections 31 and 32. City of Ashland Local Wetlands & Riparian Corridor Inventory & Assessment, July 2005, revised February 2007 Fishman/SWCA Page 2 Vegetation Wetland indicator status is according to the U.S. Fish and Wildlife Service National List of Plant Species that Occur in Wetlands: Northwest (Region 9). Soils Soils were mapped in the Soil Survey of Jackson County Area, Oregon (USDA SCS 1993). The vast majority of the study area is mapped as containing hydric soil inclusions. The only area of mapped hydric soils in the study area is located along Kitchen Creek. National Wetlands Inventory & Previous Wetland Inventory Approximately fifty wetlands were mapped in the National Wetlands Inventory (NWI) on the Ashland, Oregon NWI quadrangle. A few mapped wetlands are associated with streams, but the majority of wetlands appear to be isolated. A field survey of Ashland's wetlands was conducted by two Southern Oregon University students in 1990. The 1990 study area generally coincided with the study area of the present inventory, with the exception of that the previous inventory did not include the area located outside the City limits and inside the UGB in Sections 5, 31, and 32. The 1990 inventory focused almost exclusively on field verifying the presence of NWI-mapped wetlands, collecting sample plot data, and photodocumenting the wetlands. Floodplain The floodplain was mapped by the Federal Emergency Management Agency on the Flood Insurance Rate Map for the City of Ashland, Oregon. A 100-year floodplain is mapped along Ashland, Bear, Clay, Emigrant, Hamilton, and Neil creeks. The City of Ashland modified the FEMA floodplain boundaries following the 1997 flood, including mapping the 100-year floodplain adjacent to Cemetery Creek. Department of State Lands Files Fishman/SWCA obtained copies of wetland determinations, delineations, and permit applications within the study area from the Department of State Lands. A list of the DSL files obtained along with their approximate locations and current status of these wetlands is included in Appendix 2. Wetland delineation boundaries from maps included in DSL files were hand mapped onto aerial photograph base maps and were field verified where permission to access was granted. Aerial Photographs & GIS Data Fishman/SWCA obtained black and white aerial photographs dated April 16, 1998, which showed spring hydrology, and color aerial photographs dated July 2001 from the City of Ashland. The 1998 aerial photos were previously used by the City of Ashland Geographic Information Department to prepare a Geographic Information System (GIS) layer of streams, ditches and ponds in the study area. City of Ashland Local Wetlands & Riparian Corridor inventory & Assessment, July 2005, revised February 2007 Fishman/SWCA Page 3 Scope of Work Local Wetlands Inventory A Local Wetlands Inventory has been prepared in accordance with the Department of State Lands Local Wetlands Inventory Standards and Guidelines (OAR 141-086-0180 through 141-056-0240; effective July 1, 2001). Fishman/SWCA mapped all wetlands greater than 0.5 acre according to the LWI rules. The approximate locations of many wetlands less than 0.5 acre in size were also mapped. These small wetlands are identified as "possible wetlands" on the LWI maps. Many isolated man-made ponds are present in the study area, most of which are less than 0.5 acre. Man-made ponds were also included on the LWI maps. Mapping protocol follows the DSL LWI rules and wetland boundaries have been digitized in an ESRI-compatible format for use by the City and DSL. Wetland Assessment and Determination of Locally Significant Wetlands Wetlands greater than 0.5 acre in size have been assessed using the Oregon Freshwater Wetland Assessment Method (OFWAM) as required by the LWI rules. The OFWAM assessment consisted of evaluating Wildlife Habitat, Fish Habitat, Water Quality, and Hydrologic Control functions. Per the Department of State Lands Administrative Rules for Identifying Significant Wetlands (OAR 141-86-300 through 141-86-350), if the assessed wetland unit provided diverse wildlife habitat, intact fish habitat, intact water quality function, or intact hydrologic control function, then the wetland was determined to be significant. Wetlands not meeting the significance criterion based upon the OFWAM assessment were also evaluated according to the other criteria for determining Locally Significant Wetlands established by DSL. These criteria include (but are not limited to): the wetland or a portion of the wetland is within a horizontal distance less than one-fourth mile from a water quality limited water body (DEQ's .303(d) list) and its water quality function is intact or impacted or degraded; the wetland contains one or more rare plant communities; the wetland is inhabited by any species listed by the federal government as threatened or endangered or listed by the state as sensitive, threatened or endangered; or the wetland has a direct surface water connection to a stream segment mapped by ODFW as habitat for indigenous anadromous sahnonids and the wetland is determined to have intact or impacted or degraded fish habitat function, Riparian Corridor Inventory Although the Goal 5 Rule is very specific regarding Local Wetlands Inventory methodology, the Goal 5 Rule does not include a prescribed method for the preparation of a Riparian Corridor Inventory. Discretion provided to local communities through the Goal 5 rule allows for inventory methods which are created by the City, reviewed by its' citizens, and implemented in a manner that best fits with the local natural resources. The process of determining an exact location of a riparian corridor requires an on-site resource delineation. Even among the experts, the definition of "riparian" and the position of the boundary is often debated. City of Ashland Local Wetlands & Riparian Corridor Inventory & Assessment, July 2005, revised February 2007 Fishman/SWCA Page 4 Determination of Significant Riparian Corridors Goal 5 provides a Safe Harbor optional course of action rather than following the standard Goal 5 process, including the ESEE decision process. The Safe Harbor criteria identified under OAR 660-023-0090(5) establish a standard setback distance from all fish-bearing lakes and streams as follows: (a) Along all streams with average annual stream flow greater than 1,000 cubic feet per second (cfs) the riparian corridor boundary shall be 75 feet upland from the top of each bank. (b) Along all lakes, and fish-bearing streams with average annual stream flow less than 1,000 cfs, the riparian corridor boundary shall be 50 feet from the top of bank. (c) Where the riparian corridor includes all or portions of a significant wetland as set out in OAR 660-023-0100, the standard distance to the riparian corridor boundary shall be measured from, and include, the upland edge of the wetland. (d) In areas where the top of each bank is not clearly defined, or where the predominant terrain consists of steep cliffs, local governments shall apply OAR 660-023-0030 rather than apply the safe harbor provisions of this section. Public Involvement Process A newspaper article was published in the Ashland Daily Tidings on May 23, 2003 notifying the public of the onset of the Local Wetlands Inventory and Riparian Corridor Inventory. A second newspaper article appeared in the Medford Mail Tribune on July 23, 2003 describing the status of the inventory process. Fishman/SWCA conducted two public open house meetings for the project. The first meeting was held on June 4, 2003 to present the Goal 5 requirements and inventory process. The second meeting was held on November 20, 2003 to present the draft inventory results and maps and to receive public comments on the draft maps. Approximately two dozen citizens attended the second meeting. A third public meeting will occur to present the final inventory and maps to the City planning commission. Local Wetlands Inventory and Assessment (OAR 660-023-0090) Wetland Definition Wetlands are federally defined as "areas that are inundated or saturated by surface or ground water at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions" (Environmental Laboratory 1987). In other words, wetlands typically display three wetland criteria: a predominance of hydrophytic (wetland) vegetation, the presence of hydric (wet) soils, and wetland hydrology (ponding or near- surface saturated soils for at least 5 percent of the growing season; typically 11 days or so City of Ashland Local Wetlands & Riparian Corridor Inventory & Assessment, July 2005, revised February 2007 Fishman/SWCA Page 5 during the growing season. According to the Jackson County soil survey, the growing season in Medford is April 7th through November 3`1 (the growing season may vary annually). Wetland Methodology The Goal 5 rule is very specific in the method required for wetland inventories. The wetland inventory must be prepared using OAR 141-086-0210 through 0240. The product of the wetland inventory is a Local Wetlands Inventory (LWI). The Oregon Department of State Lands (DSL) must approve the LWI. Prior to conducting field work, background information was reviewed in the office to identify possible wetland areas and to prioritize sites for field verification. Background information included USGS topographic map, national wetlands inventory map, Jackson County soil survey, and FEMA floodplain maps; DSL wetland determination/delineation and permit files; two-foot contour mapping from the City; and 1998 and 2001 aerial photos from the City. Field work included verification of the presence or absence of NWI mapped wetlands and wetlands previously identified in DSL files; identification of previously unmapped wetlands areas greater than 0.5 acre; and identification of possible wetlands less than 0.5 acre, even though these areas are not required to be mapped according to LWI standards. Identification of new (i.e. previously unmapped) wetland areas was facilitated by field visits of sites which contained either a topographic drainage on the 2-foot contour maps or a wetland hydrology signature visible on the aerial photographs. Letters requesting permission to access were mailed to 1,513 property owners. The City sent out letters to the property owners requesting written permission to access these parcels. The list of parcels for which permission to access was requested was generated primarily based upon a GIS query identifying parcels containing either NWI or City mapped streams, wetlands or ponds, parcels mapped within the 100-year floodplain, and parcels located within 50 feet of any one of these mapped resource boundaries. In addition, several parcels which contained either a topographic drainage based upon 2-foot contours or a wetland hydrology signature on the aerial photographs were also included on the list. Of the approximately 1,500 letters, the City received 589 yes responses and 104 no responses. Field work was conducted on June 3, 4, 5, 24, 25, and 26, 2003. Properties for which on-site data collection was allowed were identified on a tax lot base map which was color coded to identify publicly-owned parcels as well as properties for which permission to access was either granted or granted with conditions (i.e. call to notify property owner prior to site visit). On-site data collection consisted of either preparation of wetland determination sample plot data sheets documenting vegetation, soils, hydrology, and topography (included in Appendix 3) or field notes recording our visual observations of one or more of these parameters. No on-site data was collected on parcels for which permission to access was not granted or for which no response to the public notice requesting permission to access was received by the City. For areas where permission to access was not granted, off-site data was collected where possible by viewing the site with the use of binoculars from adjacent roads, parking lots or public City of Ashland Local Wetlands & Riparian Corridor Inventory & Assessment, July 2005, revised February 2007 Fishman/SWCA Page 6 properties. Base maps used for field work and mapping consisted of 2001 color aerial photographs plotted at a scale of 1 inch to 300 feet. The City's stream, ditches and ponds GIS layer, which was created based on interpretation of 1998 aerial photographs, and the NWI mapping were overlayed onto the aerial photographs. Wetland and riparian boundaries, sample plots, and off-site observation points were hand mapped on the aerial photograph base maps in the field. Wetlands were identified based on the methodology contained in the 1987 Corps of Engineers Wetlands Delineation Manual (Environmental Laboratory 1987), used by the Department of State Lands. Wetlands generally include swamps, marshes, bogs, and similar areas, but also include seasonally wet meadows, farmed wetlands and other areas that may not appear "wet" at all times throughout the year. Aerial photograph signatures of wetland habitat types were groundtruthed at the start of the inventory at publicly owned sites including the Ashland Demonstration Wetlands and adjacent BMX park and at the North Mountain Nature Park. Wetland habitat types were labeled according to Cowardin class. Wetland habitat types present in the study area include: palustrine scrub- shrub (PSS), palustrine emergent (PEM), and palustrine open water (POW). Wetland boundaries, sample plot locations, and field observation points were mapped by hand on the color aerial photo base maps. Wetland boundaries and other data were then digitized onto digital aerial photographs in a Geographic Information System. The GIS attribute tables contain data for each wetland polygon including unique polygon ID number, wetland unit number, habitat type, wetland acreage, and DSL file number (if any). The locations of several isolated wetlands that were too small to be inventoried according to DSL rules (<0.5 acre) were mapped approximately as "possible wetlands". In addition, several other areas that appeared to be wetland from off-site, but for which the presence of wetland could not be field verified since permission to access these properties was not granted, were also mapped as possible wetlands. Many isolated man-made ponds are present in the study area, most of which are less than 0.5 acre. Man-made ponds were mapped separately from possible wetlands and wetlands greater than 0.5 acre. Wetland summary sheets have been prepared for each wetland unit. Wetland summary sheets include the site name, site code, general location, Township, Range, and Section location, DSL file number (if any), acreage, Cowardin (NWI) classification, hydrogeomorphic classification, hydrologic basin, mapped soils, sample plot numbers (if any), date(s) of field work, dominant vegetation, primary hydrology source, OFWAM summary, significance determination, and general wetland description including basis for wetland boundary determination. Wetland summary sheets are included in Appendix 4. The approximate locations of potential wetland mitigation/restoration sites are also required to be identified according to DSL's local wetlands inventory standards and guidelines. According to OAR 141-086-210 (19), "Vacant, former wetlands, consisting mostly of relict (dewatered) hydric soils, which are five (5) acres or larger in size shall be identified and mapped as potential wetland mitigation or restoration sites...." No sites City of Ashland Local Wetlands & Riparian Corridor Inventory & Assessment, July 2005, revised February 2007 Fishman/SWCA Page 7 within the study area meeting these criteria were identified; therefore, a map of potential wetland mitigation/restoration sites is not included in the LWI. Wetland Assessment Criteria Wetlands were assessed using the Oregon Freshwater Wetland Assessment Methodology (OFWAM; Roth et al. 1996), which evaluates wetland functions and values relative to other wetlands within the study area. The four functions listed below were assessed for each OFWAM unit, and each function was rated high, medium or low based on how many of the criteria listed below for each function were met. OFWAM evaluation sheets , are included in Appendix 5. OFWAM wetlands of special interest for protection and wetland characterization evaluation sheets which evaluate general watershed characteristics are included in Appendix 6. Wildlife Habitat - The following criteria contribute to wetlands having high wildlife habitat function: two or more Cowardin wetland classes (i.e. forested, scrub-shrub, emergent) are present; woody vegetation is the dominant wetland vegetation cover type; there is high interspersion among Cowardin classes; more than one acre of open water is present; the wetland is connected to other wetlands or bodies of water by surface water (stream, lake, pond, ditch, or culvert); no upstream or adjacent stream reaches are listed as water quality limited: the dominant existing land use within 500 feet of the wetland's edge is exclusive forest use or open space; and greater than 40 percent of the wetland's edge is bordered by a vegetated buffer at least 25 feet wide. Fish Habitat - The following criteria contribute to wetlands having high fish habitat function: more than 75 percent of the stream is shaded by stream-side (riparian) vegetation; the stream is in a natural channel, or modified portions of the stream are returning to a natural channel; more than 25 percent of the entire stream contains instream structures such as large woody debris, floating submerged vegetation, large rocks, or boulders; no upstream or adjacent stream reaches are listed as water quality limited; the dominant existing land use within 500 feet of the wetland's edge is exclusive forest use or open space; and salmon, trout or sensitive species are present in a stream, lake or pond associated with the wetland at some time during the year. Water Ouality Protection - The following criteria contribute to wetlands having high water quality protection function: the wetland's primary source of water is surface flow, including streams and ditches, or precipitation; there is evidence of flooding or ponding during a portion of the growing season; wetland vegetation cover is greater than 60 percent; the wetland is greater than 5 acres in size or is between 0.5 acre and 5 acres in size and is connected to other wetlands within a 3 miles radius by surface water (stream, ditch, canal or lake); the dominant existing land use within 500 feet of the wetland's edge is developed uses or agriculture; and one or more upstream or adjacent stream reaches are listed as water quality limited, Hydrologic Control - The following criteria contribute to wetlands having high hydrologic control function: the wetland is located within the 100-year floodplain or within an enclosed basin; there is evidence of flooding or ponding during a portion of the City of Ashland Local Wetlands & Riparian Corridor Inventory & Assessment, July 2005, revised February 2007 Fishman/SWCA Page 8 growing season; the wetland is greater than 5 acres in size; waterflow out of the wetland is restricted (beaver dam, concrete structure, undersized culvert) or the wetland has no outlet; woody vegetation is the dominant wetland vegetation cover type; the dominant existing land use within 500 feet of the wetland on the downstream or downslope edge of the wetland is developed uses; and the dominant land use in the watershed upstream from the assessment area is urban or urbanizing. OFWAM Units Fourteen wetland units (W I — W14) were inventoried and assessed. Wetland units are listed below along with their Township, Range and Section, general location, Cowardin wetland habitat classification, and wetland acreage. Wetland units may contain one or more wetland areas. Wetlands along the same stream reach with the same hydrology source and adjacent land use are grouped into the same OFWAM unit for assessment purposes. Similarly, if a wetland is bisected by a road crossing and each wetland area contains similar characteristics, they are grouped into the same wetland unit. Eleven wetland units were associated with streams or were hydrologically connected to a stream via roadside or agricultural drainage ditches. Three (W2, W8 and W9) wetlands did not contain a surface water connection to a stream or other wetland and were therefore determined to be isolated. Narrow wetland fringes, ranging from 1 to 5 feet wide, were present along several streams within the study area. These wetland fringes were much smaller than 0.5 acre (the minimum wetland size required by DSL to be mapped) and are not included in the OFWAM units in the table below. It was not possible to map wetland fringes given the map scale of a wetland inventory. Wetland fringes were included within the riparian corridor mapping along streams in the study area, including forested wetland fringes along Ashland Creek and Bear Creek, TABLE 1.

The OFWAM assessment consisted of evaluating Wildlife Habitat. Fish Habitat, Water Quality, and Hydrologic Control functions. Per the Department of State Lands Administrative Rules for Identifying Significant Wetlands (OAR 141-86-300 through 141-86-350), if the assessed' wetland unit provided diverse wildlife habitat, intact fish habitat, intact water quality function, or intact hydrologic control function, then the wetland was determined to be locally significant. Wetlands WI, W4-W9 and WI 2-W 14 were determined to be locally significant wetlands according to this methodology. Although Wetland W2 displays intact water quality function, it is excluded from the locally significant wetland criteria according to OAR 141-086-0350(1) "Exclusions. Regardless of their standing in relation to the criteria in OAR I41-086-0350(2) or (3) of these rules, wetlands shall not be designated as locally significant if they fall within any one of the following categories:...(E) Of any size and created for the purpose of wastewater treatment...." Three wetlands (W3, W10 and W11) did not meet the significance criterion based upon the OFWAM assessment and were therefore evaluated according to the other criteria for determining Locally Significant Wetlands established by DSL. These criteria include: the wetland or a portion of the wetland is within a horizontal distance less than one-fourth mile from a water quality limited water body (DEQ's 303(d) list) and its water quality function is intact or impacted or degraded; the wetland contains one or more rare plant communities; the wetland is inhabited by any species listed by the federal government as threatened or endangered or listed by the state as sensitive, threatened or endangered; or the wetland has a direct surface water cónnection to a stream segment mapped by ODFW as habitat for indigenous anadromous salmonids and the wetland is determined to have intact or impacted or degraded fish habitat function. Wetland WIO was determined to be locally significant based on rating medium for water quality function and occurring within t1a mile of a water-quality limited stream listed by DEQ on the 303(d) list. Wetlands W3 and WI 1 did not meet any of these criteria and were therefore determined to be non-locally significant. City of Ashland Local Wetlands & Riparian Corridor Inventory & Assessment, July 2005, revised February 2007 Fishman/SWCA Page 10 The table below summarizes the wetland function ratings and wetland significance for each OFWAM unit. OFWAM evaluation sheets for each unit are included in Appendix 5, and OFWAM wetlands of special interest for protection and wetland characterization evaluation sheets are included in Appendix 6. A complete list of all vegetation observed in wetlands and uplands in the study area is included in Appendix 7. TABLE 2.

' 4 Wetland W10 was determined to be locally significant based on rating medium for water quality function and occurring within 1/4 mile of a water-quality limited stream listed by DEQ on the 303(d) list. Status of National Wetlands Inventory Mapped Wetlands . We attempted to field verify the presence or absence of all wetlands mapped on the NWI in the study area. Several of the. Iarger NWI-mapped wetlands have been incorporated into the wetlands mapped in the local wetlands inventory, including units W3, W8, W9, W 10 and WI 3. Many of the NWI-mapped wetlands were determined to be man-made ponds and are mapped as ponds on the local wetlands inventory maps. Several wetlands mapped as less than 0.5 acre in size on the NWI could not be field verified due to lack of permission to access the sites and are therefore identified as Possible Wetlands (PW) on the local wetlands inventory maps. The local wetlands inventory maps replace the national wetlands inventory maps and the City's stream, ditches and ponds GIS layer and City of Ashland Local Wetlands & Riparian Corridor Inventory & Assessment, July 2005, revised February 2007 FishrnanISWCA Page 1 I provide the most accurate inventory of wetlands inside the Ashland urban grown boundary. Riparian Corridor Inventory (OAR 660-023-0090) Riparian Corridor Definition Goals definitions: "Riparian area" is the area adjacent to a river, lake, or stream, consisting of the area of transition from an aquatic ecosystem to a terrestrial ecosystem. "Riparian corridor" is a Goal 5 resource that includes the water areas, fish habitat, adjacent riparian areas, and wetlands within the riparian area boundary. "Riparian corridor boundary" is an imaginary line that is a certain distance upland from the top of bank... Riparian Corridor Methodology The method for conducting a riparian corridor inventory is not prescribed. The Goal 5 Rule permits the application of a "Safe Harbor" setback distance to all fish bearing lakes and streams. The standard setback is 50 feet for streams with more than 1000 cubic feet per second (cfs) stream flow and 50 feet for fish bearing lakes and streams with less than 1000 cfs. The rule also lists the following resources that must be consulted when completing the riparian corridor inventory: • Oregon Department of Forestry stream classification maps • USGS 7.5-minute quadrangle map • National Wetland Inventory Maps • Oregon Department of Wildlife (ODFW) maps indicating fish habitat • Federal Emergency Management Agency (FEMA) flood maps • Aerial photographs Fishman/SWCA has prepared the riparian corridor inventory using a modified on-site method. Time and budget constraints typically make it unfeasible to conduct an' on-site delineation of all riparian corridors in the City. Therefore, we conducted brief on-site field visits to document vegetation and topography adjacent to streams at several locations along each stream to determine the approximate location of the riparian corridor. The location of the riparian corridor was hand mapped on the aerial photo base map (photo date 2001, scale 1 inch to 300 feet). Two foot contour data and vegetation signatures on the aerial photos were used to approximate the location of the riparian corridor for areas that were not field verified. For areas where permission to access was not granted, off-site data was collected if possible by viewing the site with the use of binoculars from adjacent roads, parking lots or public properties. No field data was collected for Strawberry Creek or Twin Creek since permission to access the properties City of Ashland Local Wetlands & Riparian Corridor Inventory & Assessment, July 2005, revised February 2007 Fishman/SWCA Page 12 containing these small sections of stream was not granted, and the streams were not visible from adjacent public roads. Field work was conducted on June 3, 4, 5, 24, 25, and 26, 2003. Riparian summary sheets include the site name, Township, Range, and Section location, sample plot numbers (if any), dates(s) of field work, dominant vegetation, and general riparian corridor description. Riparian summary sheets are included in Appendix 8. Riparian Corridor Units Riparian corridors were mapped along all streams in the study area, which include: o Ashland Creek o Ashland Creek Tributary 1 o Beach Creek o Bear Creek o Bear Creek Tributary 1 o Cemetery Creek o Clay Creek o Clear Creek o Emigrant Creek o Fordyce Creek o Golf Course Creek o Hamilton Creek o Hamilton Creek Tributaries 1 & 2 o Kitchen Creek o Knoll Creek o Mountain Creek o Neil Creek o Paradise Creek o Paradise Creek East o Pinecrest Creek o Roca Creek o Strawberry Creek o Tolman Creek o Twin Creek o Wrights Creek o Wrights Creek Tributaries 1 - 5 Determination of Significance for Riparian Corridor Areas Significant riparian corridors mapped using the Safe Harbor criteria identified under OAR 660-023-0090(5). The Safe Harbor criteria establish a standard setback distance from all fish-bearing lakes and streams as follows: a) Along all streams with average annual stream flow greater than 1,000 cubic feet per second (cfs) the riparian corridor boundary shall be 75 feet upland from the top of each bank. (Top of bank is defined by the DSL as "bankfull stage," and in the absence of obvious tops of bank can be approximated by the two-year flood City of Ashland Local Wetlands & Riparian Corridor Inventory & Assessment, July 2005, revised February 2007 Fishman/SWCA Page 13 elevation. Most streams in the City of Ashland have well-defined channels and the top of bank is in most cases easily observed in the field.) b) Along all lakes, and fish-bearing streams with average annual stream flow less than 1,000 cfs, the riparian corridor boundary shall be 50 feet from the top of bank. c) Where the riparian corridor includes all or portions of a significant wetland, the standard distance to the riparian corridor boundary shall be measured from, and include, the upland edge of the wetland. d) In areas where the top of each bank is not clearly defined, or where the predominant terrain consists of steep cliffs, local governments shall apply OAR 660-23-030 (the inventory process defined in the subject document) rather than apply the safe harbor provisions. Fish-bearing streams were determined based upon ODFW StreatrnNet data and a map from the Oregon Department of Fish and Wildlife showing stream segments where fish presence was documented based upon ODFW observations during electroshocking and snorkel surveys conducted in 1997 through 2000. The ODFW map identifies Ashland Creek, Bear Creek, Emigrant Creek, Kitchen Creek, Neil Creek, and Tolman Creek as being fish-bearing within the study area. According to the Safe Harbor criteria, a 50 foot buffer is required adjacent to these streams. Most of the streams in Ashland are not documented as fish-bearing, and therefore would not be protected under the safe harbor requirements. Short sections of Clay Creek, Hamilton Creek and Wrights Creek located downstream of the study area were mapped as fish-bearing; however, the streams are not documented as being fish-bearing within the study area, so a safe harbor has not been applied to these streams. The City currently requires IO to 20 foot buffers adjacent to all streams within the Ashland urban growth boundary, including those that are not fish-bearing. The City of Ashland is currently discussing alternatives for additional inventory, assessment, and regulation of riparian corridors not addressed under the Safe Harbor.

Note: although Wetland W2 displays intact water quality function, it is excluded from the locally significant wetland criteria according to OAR 141-086-0350(I) since it was created for the purpose of wastewater treatment. The wetland is also non-jurisdictional since it was created in upland soils and is smaller than 1 acre. Description of the wetland, including topographic position, land uses, alterations. and the basis for the wetland boundary determination: The Ashland Demonstration Wetlands consist of 3 excavated ponds, 0.16, 0.22 and 0.26 acre in size, dominated by narrow-leaf cattail and hardstem bulrush. The upper pond also contained poison hemlock (noxious) and floating pennywort with red-osier dogwood, rose and willow shrubs planted on the side slopes. The middle pond also contained globepodded hoarycress, a noxious species. The ponds were constructed in 1996 and were lined and planted. The ponds were built as an experimental system to determine their effectiveness for removing City of Ashland Local Wetlands and Riparian Corridor Inventory & Assessment, July 2005, revised February 2007 Fishman/SWCA Page 2 City of Ashland Local Wetland and Riparian Corridor Inventory and Assessment Wetland Summary Sheet Wetland 2, continued phosphorous from the City's wastewater. The ponds received 10,000 gallons per day from the sewage treatment plant tintil 1998 or 1999 when the experiment was discontinued since preliminary results revealed that this type of natural treatment system would not be adequate to meet DEQ's phosphorous standard given the volume of the City's wastewater and small size of the treatment ponds. The wetland/upland boundaries are well-defined by topography and a change to non-hydrophytic vegetation surrounding the ponds consisting of ripgut brome, ryebrome, tall fescue, hairy vetch, and two-color lupine. Three rectangular areas were excavated immediately north of the Ashland Demonstration Wetlands to provide stormwater infiltration. These areas are currently dominated by non-hydrophytic vegetation and do not meet the wetland criteria. The upper two excavated areas are dominated by dead giant reed (invasive in California), and the lower excavated area is dominated by a brome species. These three excavated areas are not included in the mapping for wetland unit 2. City of Ashland Local Wetlands and Riparian Corridor Inventory & Assessment.

Wildlife Habitat: Medium 1 Cowardin class, no woody veg., <0.5 acre open water Fish Habitat: Low wetland does not include a stream, lake or pond Water Quality: Medium primary water source = groundwater, evidence of popding, high veg. cover Hydrologic Control: Medium outside floodplain, unrestricted outlet, upstream land use is developed Determination of Goal 5 Locally Significant Wetland: Not locally significant but still jurisdictional Description of the wetland, including topographic position. land uses, alterations, and the basis for the wetland boundary determination: The Billings Ranch residential subdivision site was under construction at the time of the site visit. This wetland was viewed from off-site from Nevada Street using binoculars. Grading activity was occurring, and orange construction fencing was present adjacent to the wetland area. Vegetation was dominated by grasses, including common velvetgrass (all species could not be identified with binoculars). Trace amounts of teasel, hardstem bulrush, rush and dock were also noted. The wetland delineation report describes the portion of the wetland to be impacted as being dominated by upland and wetland grasses (often facultative wetland grasses) with lesser amounts of rushes and sedges. The portion of the wetland to be protected is described as having bulrush and cattails. City of Ashland Local Wetlands and Riparian Corridor Inventory & Assessment, July 2005, revised February 2007 Fishman/SWCA Page 4 City of Ashland Local Wetland and Riparian Corridor Inventory and Assessment Wetland Summary Sheet Wetland 3, continued This site was delineated in 2002 (DSL WD 2002-0472).

The Granite Street Reservoir is present on Ashland Creek at the upstream end of the study area. The reservoir is surrounded by a fringe of Himalayan blackberry with black cottonwood, white alder, Pacific willow, Oregon ash, Oregon white oak and big-leaf maple trees. The upstream portion of Ashland Creek meanders through Lithia Park for approximately 1 mile. Ashland Creek receives flow from Lithia Springs. The stream channel ranges from 15 to 30 feet wide and generally widens as it trends downstream. Cobbles, boulders, and woody debris provide good in-stream structure, and the stream is well shaded by a riparian and upland forest consisting of white alder, big-leaf maple, and Oregon ash. Invasive species including Himalayan blackberry and English ivy are present in a few areas along Ashland Creek. The stream channel is confined by well- defined stream banks in Lithia Park. No wetland benches were noted; however, a few off-channel shallow water areas were created during the 1996 flood. These shallow water areas contain mannagrass, common velvetgrass, American speedwell, sawbeak sedge, and willow-herb. Two off- line ponds are present adjacent to Ashland Creek. Both ponds have concrete lined sides with embedded boulders and contain floating "Lake Restorer" islands designed to improve water quality. The upper pond is the larger pond and is used by wood ducks, mallards, and turtles. A few topographic draws were noted in the steep hillside above Ashland Creek, indicating that intermittent drainages may flow downslope to Ashland Creek. At the downstream end of Lithia Park beginning at the bridge at Calle Guanajuato Way, Ashland Creek is confined within a series of concrete sidewalls, some with adjacent planter boxes containing red-osier dogwood and willow shrubs. The downstream portion of Ashland Creek ranges from 10 to 20 feet wide and is bordered predominantly by residential development, a few agricultural parcels and the Ashland Community Garden. Ashland Creek contains good in-stream structure with many, cobbles and boulders as well as City of Ashland Local Wetlands & Riparian Corridor Inventory & Assessment, July 2005, revised February 2007 Fishntan/SWCA Page 1 City of Ashland Local Wetland and Riparian Córridor Inventory and Assessment Riparian Summary Sheet Ashland Creek, continued in-stream woody debris in some areas. Portions of the stream channel bottom are comprised of bedrock. Ashland Creek is confined within its stream banks dice to topography of the adjacent side slopes and armoring of banks with riprap and boulders in some areas; therefore, wetland benches are generally not present along Ashland Creek. A riparian and upland forest corridor generally ranging from 50 to 150 feet wide is present along Ashland Creek. Development along Ashland Creek has resulted in some fragmentation and operi canopy areas, but the stream is well-shaded in many areas. Dominant riparian vegetation consists of white alder, black cottonwood, Oregon ash, Pacific willow, sandbar willow, weeping willow and red-osier dogwood. Some areas of Himalayan blackberry and English ivy were noted, although invasive species are not generally dominant along the stream corridor. Two large man-made open water ponds are present near the confluence of Ashland Creek with Bear Creek just downstream of the Ashland sewage treatment plant. The east pond is seasonal and becomes an emergent wetland in the summer and was therefore mapped as wetland unit W14. The west pond (1.9 acres) is accessible from a trail off the end of Glendower and appears to be a diversion pond from Ashland Creek. The pond was reported to have been constructed approximately 30 years ago. An overflow structure to Ashland Creek was noted at the west end. The pond contains a fringe of reed canarygrass, teasel. and poison hemlock with scattered black cottonwood, sandbar willow, Oregon ash and rose shrubs. This pond appears to contain water year-round and was therefore mapped as a pond rather than a wetland. Wildlife use noted includes wood duck, mallards and western pond turtle.

A weir structure is present on Beach Creek at the BPA substation site. Sedimentation has occurred upstream of the weir and a narrow wetland fringe is present containing cattail, curve-pod yellow-cress, poison hemlock and Pacific willow. A few Oregon ash and willow shrubs are also present, along with planted big-leaf maple and Oregon white oak saplings. Downstream vegetation along the stream channel consists of spearmint, teasel, bittersweet nightshade and yellow starthistle. Uplands consist of downy cheat grass, blue wildrye, Italian ryegrass, and planted big-leaf maple saplings. Downstream of the BPA substation, Beach Creek and an emergent wetland swale flow northwest through the North Mountain Nature Park to Bear Creek. Three on-line ponds (upper, middle and lower ponds) are present on Beach Creek. These ponds and associated wetlands were mapped as wetland unit 7. The headwaters of Beach Creek originate in the steep hillside south of Ashland Street. Much of the stream is culverted through residential development. Beach Creek is intermittent where it is daylighted above Ashland Street. Downstream of Beach Street, the stream is bordered by steep side slopes with dense Himalayan blackberry and Pacific willow, black cottonwood and weeping willow trees in the riparian area. Adjacent uplands contain catchweed bedstraw, periwinkle, Himalayan blackberry, Oregon white oak and ponderosa pine. Upstream of Beach Street, Beach Creek is forked. The east fork is approximately 1 foot wide and flows through a rock and flagstone water feature through a backyard area and then continues upslope where it is confined at the bottom of steep Himalayan blackberry covered side slopes with tall fescue, bulbous bluegrass, and Oregon white oak further upslope. The west fork is an undefined channel at the bottom of a steep topographic ravine with very sparse herb layer that had been recently cleared of blackberry. Oregon white oak, madrone, big-leaf maple, Douglas fir and ponderosa pine were present in the tree canopy.

The downstream portion of Bear Creek varies from 30 to 75 feet wide. Bear Creek was observed at the Mountain Avenue bridge and the Bear Creek Greenway Trail bridge (Talent-Ashland Trail segment). The portion of Bear Creek Iocated within the study area is bordered mostly by undeveloped land. Bear Creek has good in-stream structure with many cobbles and nice channel meanders. Bear Creek is topographically confined within its stream banks; therefore, wetland benches are generally not present. The stream is well-shaded by its riparian corridor which contains a mixture of native trees and shrubs and is generally dominated by black cottonwood, white alder, and Oregon ash in the tree canopy and by Pacific willow, sandbar willow and Piper's willow in the shrub layer. The stream channel is inaccessible in many areas due to dense thickets of Himalayan blackberry in the riparian corridor. An approximately 20 foot wide wetland bench containing cattail, yellow iris, American speedwell and soft rush is present on the north bank, downstream of Mountain Avenue. The stream channel is confined in this location by a steep Himalayan blackberry covered slope on the south bank. Two great blue heron nests with herons were observed in black cottonwood trees in the riparian corridor near Mt. Meadows Drive. Adjacent uplands contain a variety of upland pasture grasses, yellow starthistle, poison hemlock, Himalayan blackberry, oak and ponderosa pine. The North Mountain Nature Park borders Bear Creek to the south at the northeast edge of the study area. The 14 acre park is being managed and enhanced by planting a variety of native species with the goal of improving the quality of fish and wildlife habitat in the Bear Creek riparian corridor. Bear Creek adjacent to the North Mountain Nature Park was approximately 30 to 35 feet wide and was flowing i to 2 feet deep and contained many in-stream cobbles and boulders.

The headwaters of the tributary originate in the steep hilislope south of the study area. The tributary flows northwesterly along the bottom of the hillslope behind several car dealerships and the Lithia Springs Inn. The stream is culverted under West Jackson Road, heads northerly through the Jackson Hot Springs RV Park, then continues northwesterly prior to being culverted under Highway 99 and joining Bear Creek, The stream varies from 3 to 10 feet wide and is bordered by a narrow emergent wetland fringe behind the Lithia Springs Inn. Wetland vegetation consists of cattail, curve-pod yellow-cress, reed canarygrass, soft rush, common horsetail, hardstem bulrush, poison hemlock, mannagrass, buttercup, forget-me-not with areas of Himalayan blackberry, willow and cherry shrubs. Oregon ash and white alder trees are present along the downstream portion. Adjacent uplands consist of brome, Himalayan blackberry, Oregon white oak, big-leaf maple, ponderosa pine, and Douglas fir. , Hydrology of the triburary is partially fed by sulfur springs, one of which was observed at the rear of the Lithia Springs Inn property. Sulfur springs also appear to be feeding a small concrete-lined pond south of West Jackson Road. Two-foot contours and black and white aerial photo coverage was not available for this area, and mapping the stream location was difficult in areas due to tree canopy cover and lack of permission to access the area.
