The Tax Parcel No. is 601 105001 and it is situated in the NE ~ of the SE ~ of Section 10, Township 26 N, Range 1 W. WM, Washington. This 5 acre parcel is rectangular in shape and is currently undeveloped although some land clearing work has been conducted in the future homesite on the west half and in the proposed driveway area on the east side of the property. Undeveloped land lies to the north and a garage on a largely undeveloped parcel lies to the south. The garage is accessed from Blueberry Hill Lane via a relatively new driveway just south of the property line. The property is currently composed of upland that was clear cut about 10 years ago and the current vegetation community is composed of 10 year old red alder, Douglas fir and western hemlock trees with thick cover of ferns and salal in the understory. The wetland was also cleared at that time and is currently dominated by emergent and shrub vegetation with very few trees actually coming back in. The vegetation community contains both upland and wetland species with upland species growing on small upland hummocks. The eastern boundary of the wetland was delineated in 2002 by Olympic Wetland Resources and at that time, the wetland was determined to be a Category II system. The western edge of the wetland was recently delineated by Wiltermood Associates and the Category II designation was confirmed during the recent delineation. The eastern boundary of the wetland was not re-delineated at this time but may be prior to completion of this project. The wetland appears to be fed mainly by a seasonally perched water table with additional winter time sources provided by upland surface water flow from an off-site swale that enters the northern tip of the wetland. It also appears to be fed occasionally by water that overflows from the off-site depressional wetland that is at least 250 feet from the north parcel boundary but only during severe rain events. Water sheet flows. through the wetland (there is no formal drainage or stream channel) and as it exits the south property line, it enters a culvert under a gravel driveway just off-site to the south. The wetland continues across the adjacent south property but it is not clear into what body of water the wetland may eventually drain. According to the Jefferson County Wetland Inventory, the wetland extends across the adjacent south property and ends abruptly about halfway across the next parcel to the south. Clearing has been conducted in an area west of the wetland in preparation of home site construction and on the east side for eventual construction of the driveway to the western building site. The proposal for this project will involve construction of the home, satellite bedroom building and pole barn outside the buffer of the wetland. The drainfield is proposed west of the wetland because the well is proposed on the east side and there is not enough room on the east side in which to install the drainfield outside the 100. foot well radius. The drainfield is also required on the west side because the soils on the east side do not perk. The legal access to the property is via Blueberry Hill Drive and a driveway is needed across the north end of the wetland to access the western building site and drainfield area. The driveway is proposed across the narrowest point of the wetland and will involve the least amount of impact. There are no other options for access to the western building site as adjacent property owners have denied use of existing driveways and Jefferson County will not allow access from Coyle Road, which lies along the west edge of the property, because of the legal access from Blueberry Hill Drive and because the site distance is poor along the on-site portion of Coyle Road. A properly sized culvert will be placed under the future driveway to permit continued flow of water into the wetland from off-site sources and will involve a bit of wetland fill, Mitigation is proposed in the form of wetland creation on the east side of the disturbed/cleared wetland because it is the most disturbed area, The delineation was completed on January 18, 2006 for the Horizon Holdings LLC using the Department of Ecology Washington State Wetlands Identification and Delineation Manual in accordance with the Jefferson County Critical Areas Ordinance. The Department of Ecology Wetland Manual requires the use of the three wetland parameter methodology (wetland hydrology, hydrophytic vegetation, and hydric soils) when making wetland boundary determinations (see Appendix C for criteria used to make wetland determinations). The delineation is also consistent with the 1987 US Army Corps of Engineers Wetland Delineation Manual. These manuals stipulate that all three parameters must be present for an area under normal circumstances to be considered wetland. Because this site is determined to be under normal circumstances as it has recovered nicely from the past clearing activities, the Routine On-Site Method was used to make the on-site wetland boundary determinations. This report was prepared for submittal to the US Army Corps of Engineers, the Washington Department of Fish and Wildlife and the Jefferson County Department of Community Development as the main supporting document for the proposed homesite construction and wetland crossing, The information contained in this report will be used by the agencies to make jurisdictional determinations concerning the regulation of the wetland fill and to follow the guidelines for preparing a mitigation plan. The report includes a discussion of the on-site wetland with respect to data collected in the field used in conjunction with information obtained from the Jefferson County Soil Survey, National Wetlands Inventory and the Jefferson County GIS Wetland Map. It includes wetland categorization, classification, buffer requirements, wetland functions values assessment and discussion of the potential impacts of future development and the wetland crossing on the delineated wetland. 2 BACKGROUND INFORMATION Jefferson County Soil Survey The on-site soils are mapped as SnC Sinclair gravelly sandy loam, 0-15 % slopes, according to the Soil Conservation Service, Soil Survey of Jefferson County Area, Washington, August 1975. Sinclair soils are not classified as hydric and it does not contain inclusions of hydric soil types. See Appendix A - 3 for site located on the soil survey and Appendix B for description of the on-site soils. National Wetland Inventory The US Fish and Wildlife Service, National Wetland Inventory (NWI), Quilcene Quadrangle, does .not map wetland on or within 200 feet of the parcel boundaries. There is wetland mapped off-site to the north that is classified as Palustrine, Scrub/shrub, Seasonally flooded. This wetland is at least 250 feet north of the property and it likely meets the Category II designation so its required 100 foot buffer will not extend onto the parcel. The wetland is large enough to be identified by the NWI but was not originally picked up during aerial photo identification because it was forested at the time the inventory was conducted. It would likely now be picked up because it has been cleared and a scrub/shrub and emergent system currently dominates this wetland. See Appendix A -4 for site located on the NWI. Jefferson County Wetland Inventory The Jefferson County Wetland Inventory map was obtained from the Jefferson County website for this report. This inventory maps a wetland system just entering the south property line about 1/3 of the way from the east line. The wetland extends southerly away from the property and no other wetlands are mapped on th~ site. The delineated on-site wetland lies just to the east of where the inventory maps wetland and it is assumed that because wetlands were not identified in the mapped area and the inventory does not also map the on-site wetland, the mapped wetland represents the on-site wetland. The inventory also indicates the scrub/shrub wetland system off-site to the north and shows it right along Coyle Road at least 250 feet north of the property, See Appendix A-5 for site located on the Jefferson County Wetland Inventory Map. Priority Species There are no Washington State Priority 1, 2, or 3 plant or animal species known to exist on the parcel (Washington Natural Heritage Program, 1993/95 update) nor were any identified during our field survey. The presence of priority species was determined using the printed edition and a data base search was not completed at this time, The absence of significant upland and wetland communities on this site would indicate that there are no habitat features available on this site or within the wetland that would make it valuable habitat for priority species. It is located at least ~ mile from the Coyle Peninsula shoreline and there 3 is no line of site to the shoreline from the property. There are also homes and roadways in the immediate vicinity that are also reducing the ability of the site to provide habitat for priority plant or animal species. WETLAND ASSESSMENT The following section describes the data collected at test holes in each of the wetlands and in the adjacent upland that was used to make the wetland boundary determination. The wetland and upland data is described in separate sections and each section includes a description of the dominant plant species, the soil profile and whether hydric conditions are present, and the presence/absence of wetland hydrology and/or wetland hydrology indicators. The dominant plant species identified by common and botanical name along with the indicators status (OBL, FACW, FAC, etc. See Appendix D for Definition of Indicator Status) as listed on the back of each data form. The presence of hydric soil conditions is examined in a 16 inch soil holes conducted at each test hole. The hydric soil criteria is met when there is a low. soil matrix chroma at 10 inches or just below the A horizons. The chromas are determined using damp soil samples that are compared to a corresponding color chip in the Munsell Soil Color Charts. The chromas were then recorded on the data sheet using Hue (YR) and Value/Chroma, Any Hue and Value with a low Chroma is typical of hydric (wetland) soils that have developed over time due to inundation or saturation by water. The presence or absence of wetland hydrology and/or wetland hydrology indicators includes the source of hydrology and direction of flow (if evident) . Wetland Classification, Wetland Category, Mitigation ratios and Required Buffers follow the description of the wetland/upland data. The delineated wetland crosses the entire width of the property on the east half and continues off-site to the south. There are no wetland areas off-site to the north although the wetland appears to receive hydrology through a seasonal swale originating to the north. There is also a seasonal upland swale conveying water into the wetland only during the winter months across the east half of the property (Appendix A-2). Water flows southerly through the wetland via sheet flow and enters a culvert under an existing gravel road just off-site to the south, Wetland continues in a southerly direction across the adjacent parcel. The eastern boundary of the wetland was delineated in 2002 by Olympic Wetland Resources and it was determined to be fairly accurate so it was not re-delineated. This delineation focused on identifying the western boundary of the wetland to facilitate the proposed road crossing and to verify that the proposed homesite is outside the required buffer. The western wetland boundary as delineated by Wiltermood Associates, Inc. is marked with 17 orange colored flags labeled WB 1 through 17 beginning at the north end and ending at the south property line. A total of 6 test holes are located in the delineated wetland and surrounding upland with Test Holes 3 and 5 located within the wetland. Test Holes 1, 2, and 6 are located in the upland areas on both sides of the wetland. Test Hole 1 4 was completed in the north swale just before it flows into the on-site wetland. There is no Test Hole 4. See Appendix A-2 for approximate location of wetland boundary flags and test holes and Appendix G for Wetland Field Data Forms 1 and 3. Vegetation The on-site wetland is comprised of a scrub/shrub emergent system that is dominated by hardhack (Spiraea douglasii) F ACW in the shrub dominated areas and slough sedge (Carex obnupta) OBL in the emergent dominated areas. Slough sedge is the dominant understory species in the hardhack dominated areas and hardhack is present at lower percentages in the slough sedge dominated areas. There are lower percentages of other species in both communities and those species include western red cedar (Thuja plicata) F AC; red alder (Alnus rubra) FAC; Pacific crabapple (Malusfusca) FACW; salal (Gaultheria shallon) FACU; sword fern (Polystichum munitum) FACU; and bracken fern (Pteridium aquilinum) F ACU, The plant communities within the wetland indicate the system was likely a forested mosaic system prior to clearing of trees with upland species (salal, sword fern and bracken fern) growing on hummocks above the wetter areas containing dominant species (slough sedge, hardhack, western red cedar, red alder and Pacific crabapple). The predominance of vegetation within the wetland is composed of plants having indicator statuses ofFACW and OBL so the hydrophytic vegetation criterion is met. See Appendix D for Definition of Indicator Status (OBL, FACW, FAC, etc.). Soils The soil at Test Holes 3 and 5 were not examined during the January 2006 delineation because standing water to a depth of 12 inches was present throughout the wetland. The soils are assumed hydric based on the presence of a peraquic moisture regime. Data collected during the Olympic Wetland Resources delineation indicate the soils are composed of a clay layer revealed within about 10 inches of the soil surface having a low matrix chroma of 2.5 Y 4/2 with mottles of 10 YR 5/6 lying beneath a slightly darker surface horizon having a matrix chroma of 10 YR 4/1. The hydric soil colors and presence of mottling indicates that the soil in the wetland meets the hydric soil criteria. The peraquic moisture regime observed during our site visit meets the hydric soil criteria and the hydric soil criteria is determined to be met for this wetland. Hydrology Standing water was present throughout the wetland to a depth of 12 inches and the debris lines above the January 18, 2006 water level, indicates water can be up to 18 inches deep in some areas. It is assumed that the soils are saturated to the surface. The source of hydrology appears mainly to be a perched water table because of the depressional position in the landscape. Water also appears to enter the wetland from swale to the north and from overland flow originating at the wetland off-site to the north but only during the winter months and only on a temporary basis following heavy rain events. A seasonal upland swale also conveys water from the east half into the wetland. Water appears to be flowing south through the wetland but not through a defined swale or stream channel. Water exits the on- site wetland at the south property line where it immediately enters a culvert under a gravel 5 driveway just off-site to the south. It is not clear if the wetland drains into other bodies of water but it likely eventually drains into a stream system at some point to the south and eventually drains into the Hood Canal to the east or Dabob Bay to the west. The wetland hydrology criterion is met in the delineated wetland because water was present as standing water and there was evidence of slightly higher water levels. The dominance by hydrophytic plant species is also a positive indicator of wetland hydrology. Wetland Classification The wetlands encountered on the property have been classified according to the U,S. Fish and Wildlife Service, Classification of Wetlands and Deepwater Habitats of the United States, Cowardin et at December, 1979. This method of wetland classification divides wetlands into a hierarchy based on their specific attributes (system, class, hydrologic regime). This system describes a wetland's association with a body of water (Estuarine, Palustrine, Riverine, etc,), while the class refers to the dominant vegetation community (aquatic bed, emergent, forest). Hydrologic regime indicates the wetland's relationship to the movement of water, The delineated wetland is a freshwater system that is dominated by forested (off-site to south), shrub and emergent plant species and appears to be at least seasonally flooded. It therefore is classified as Palustrine, Scrub/Shrub-Emergent, Seasonally flooded, which is abbreviated PFOSSEMC. Wetland Category The on site wetlands were categorized using the Department of Ecology, Wetland Rating System for Western Washington, Second Edition as required by the current Jefferson County Critical Areas Ordinance. This system utilizes a rating form that differentiates wetlands according to specific characteristics and assigns points on how well individual wetlands fit the listed characteristics. This wetland meets the criteria for a Category II system because it scored a total of 29 points on the rating forin (22 points is the minimum point total for Category II wetlands). The wetland is about 3 acres in size (including on and off-site areas) that has at least three vegetation communities (emergent, scrub/shrub and forested) with low diversity in each community and it therefore has moderate interspersion of plant communities. It has few habitat features other than downed logs and areas of ponding that do not qualify. as open water. The wetland functions to export organic matter into a stream on a seasonal basis but it does not have fish usage, The buffers are composed of at least 100 feet of forest and shrub wider for more than Ih of its circumference. See Appendix E-1 for wetland rating form. Buffer Requirements The Jefferson County Unified Development Code, Chapter 18,15 Land Use Districts Section 18.15.325 Classification/Designation of Wetlands requires 100 foot buffers from the boundaries of Category II wetland systems. The standard buffer can be maintained for the future home on the west side and the future outbuildings on the east side of the wetland. No buffer averaging or reduction is proposed at this time. See Appendix E-2 for Jefferson County Buffer Requirements. 6 Mitigation Requirements The project is requiring a.driveway across the northern portion of the wetland to obtain access to the western building site, The drainfield is positioned near the proposed home site on the west side of the wetland because the well is proposed on the east side and a drainfield cannot be accommodated outside the 100 foot well radius on the east side. The Jefferson County Unified Development Code requires mitigation for wetland and buffer impacts at a ratio of 2: 1 for creation and restoration of wetland and at a ratio of 4: 1 for enhancement of wetlands in Category II emergent and scrub/shrub wetland communities. To keep the overall costs low for the proposed single family project, enhancement of . wetland and buffer is proposed at the 4: 1 ratio. Enhancement will more than adequately compensate for the minor fill required for the driveway crossing, which will likely not be greater than 500 square feet of actual wetland impact. Off-Site Wetlands The delineated wetland extends off-site to the south across an existing gravel road. According to the Jefferson County Wetland Inventory map, the wetland extends just across the adjacent south property and appears to end about midway across the next parcel. The wetland extends in a perpendicular direction from the parcel boundary so there are no additional buffers imposed on the property. The wetland mapped by the NWI and Jefferson County map is located along Coyle Road and has been documented to be about 250 feet from the parcel. The buffer from this wetland will not extend onto this site. No other wetland areas were identified within 250 feet of the parcel boundaries, FUNCTIONAL V ALVES ASSESSMENT FOR THE DELINEATED WETLAND Flood control, groundwater recharge/discharge, water quality maintenance, biological support, and many other functions are performed by wetlands, The table below lists the most common values and functions of wetlands and provides a value rating for each function. The rationale used to make rating determinations is included in this table and the determinations are made using professional knowledge with support from the Washington Department of Ecology 2004 Wetland Rating system and the WET functional evaluation method, See Appendix F for further description of wetland values and functions. !Value or FUDctiQn Wetland Rating and Rationale Storm Water Storage MODERATE-HIGH This wetland is situated in a shallow depression so it has the potential for storage of excess water during and following storm events. It dries up during the summer months so there is good storage capacity during the winter rainy season. It is unclear if it drains into a stream further to the south and so its opportunity to protect downstream buildings or habitat is not known. 7 Water Quality Protection Wetland Rating and Rationale MODERATE-HIGH The wetland contains thick patches of emergent vegetatIon and areas of woody vegetation and/or debris that are un-grazed over 90 % of the wetland so it has the potential for improvement of water quality. There are developed and/or cleared areas within 150 feet of the wetland off-site to the north and south where runoff is generated so the wetland has the opportunity to improve water uality. Groundwater Recharge LOW-MODERATE The previous delineation and report revealed that the soil substrate is composed of silty clay that precludes the downward percolation of water from this particular wetland. There is a possibility that there is recharge along the wetland edge when water levels are high enough to percolate through the more permeable upland soils around the wetland. LOW-MODERATE It appears that this wetland receives hydrology primarily from overland flow via a swale from the north and there is some flow of water across forested upland from the larger wetland off-site to the north but only occasionally during and after severe rain events. There is also some indication the wetland may also be subject to a fluctuating water table and therefore, receives water from below ground. MODERATE The wetland and its immediate buffer were clear cut several years ago and as a result, the wetland is mostly dominated by relatively open emergent and shrub vegetation communities that are essentially surrounded by cleared upland; partially developed land and roadways, It appears to provide good habitat for amphibians and small passerine bird species but because of its condition and lack of significant habitat features (snags and the like), it does not provide habitat for priority or endangered wildlife species, There is no stream association so there is no fish usa e. Biological Support Groundwater Discharge Aesthetic, Educational and Recreational Values LOW-MODERATE The wetland is too small to be of much recreational value and lacks features often associated with valuable recreation areas such as large areas of open water and an association with a salmonid bearing stream. It has some value as an educational site but only for the residents of the neighborhood as it is on privately owned land. Aesthetically, it is an attractive amenity to the site that is often desired b homeowners. 8 UPLAND DESCRIPTION The uplands have gradually sloping terrain beginning at Coyle Road and ending at the western wetland boundary with level terrain beyond the wetland to the east line. The entire site was cleared about 10 years ago and the vegetation re-growing is composed of young conifer and deciduous trees with thick cover by high shrubs, The more recently cleared areas are outside the eastern and western wetland buffers and precautions were taken to ensure that no impact occurred to the wetland as a result of the clearing and involved retention of logging debris placed along the edge of the cleared areas. Data was collected in the upland areas adjacent to the wetland to verify the delineated wetland boundary. Test Hole 1 is located in the swale located north of the wetland; Test Hole 2 is in located in upland that where water was flowing into the west side of the wetland at the time of the field delineation (January 18,2006) due to heavy rains and Test Hole 6 is located west of the wetland at the south end. See Appendix A-2 for location of Upland Test Holes 1,2, and 6 and Appendix G for Upland Data Forms 1,2 and 6. Test Hole #1 This test hole was established just off-site to the north to document the absence of wetlands in an area delineated as wetland by Olympic Wetland Resources. This area is dominated by low growing species that are re-vegetating after the site was clear cut. The dominant species in this area is dominated by western rhododendron (Rhododendron macrophyllum) UPL; salal (Gaultheria shallon) FACU and sword fern (Polystichum munitum) FACU. Lower percentages of wild cherry (Prunus emarginata) F ACU; Douglas fir (Pseudotsuga menziesii) FACU; evergreen huckleberry (Vaccinium ovatum) FACU; hardhack (Spiraea douglasii) FACW; velvet grass (Holcus lanatus) FAC; bracken fern (Pteridium aquilinum) FACU; and foxglove (Digitalis purpurea) F ACU are also present in this upland area. The soil test hole revealed a single layer gravelly sandy loam profile that has a non-hydric matrix chroma of 10 YR 4/3. Standing water was present in this area due to heavy rainfall that had occurred prior to the delineation site visit but was not present in the soil profile. The hole began filling up with water as the hole was dug indicating that the soils are not saturated with ground or surface water for a significant duration of the growing season. There was no evidence of wetland hydrology in this area. Test Hole #2 Test Hole 2 is located west of the wetland in an area of water sheet flowing apparently through the upland from the off-site wetland due to copious amounts of rainfall occurring within the weeks prior to the delineation site visit. This area has a forest canopy that has 60% closure and is dominated by western red cedar (Thuja plicata) F AC and red alder (Alnus rubra) F AC. The understory is dominated by nearly 100% cover by sword fern (P. munitum) F ACU with lesser percentages of evergreen huckleberry (V ovatum) F ACU; salal (G. shallon) FACU and slough sedge (C obnupta) OBL. The soil test hole revealed a single layer sandy loam profile that has a non-hydric matrix chroma of2.5 Y 4/3, without mottling. Water was sheet flowing through this area during the delineation site visit due to the tremendous amount of rainfall occurring in the weeks prior to the site visit. Water was about 9 4 inches deep and was observed flowing downslope to the wetland over the ground instead of through a defined channel. It was determined to not be wetland hydrology because of the soils lacking hydric soil matrix chroma and other hydric soil characteristics and the vegetation is dominated by non-wetland plant species. Test Hole #6 Test Hole 6 is located in upland west of the delineated wetland toward the south end of the property. The vegetation in this area was logged along with the rest of the site and the community is currently recovering. The young trees in this area include red alder (A. rubra) FAC; western hemlock (Tsuga heterophylla) FACU; Douglas fir (P. menziesii) FACU; and madrona (Arbutus menziesii) UPL. The thick understory is dominated by a mixture of salal (G. shallon) F ACU and sword fern (P. munitum) F ACU with lower percentages of evergreen huckleberry (V ovatum) FACU and slough sedge (c. obnupta) OBL. The soil test hole revealed the presence of a single layer gravelly sandy loam that has a non-hydric matrix chroma of 10 YR 4/3. Hydrology was not present in this area and there was no evidence of wetland hydrology, The areas sampled at the upland test holes are determined to be non-wetland because there are no positive indicators for any of the wetland parameters, The vegetation community is composed predominantly of upland plant species with only low percentages ofFAC or OBL species. The soils have non-hydric profile conditions (high matrix chroma, no mottles and no organic soils) and while there is hydrology in some locations, it is not considered wetland hydrology because it is occurring on the surface and is not saturating the substrate. There are no indicators of long term or wetland hydrology either on the surface of the soil or within the soil profile. POTENTIAL IMPACTS OF PROPOSED DEVELOPMENT A single family home, satellite bedroom building and a pole barn are proposed on this parcel. The well is proposed east of the wetland and because 100 feet of horizontal separation is required between an on-site drainfield and a well, the drainfield must be installed west of the wetland, There is little room outside the 100 foot radius on the east side of the wetland in which to construct a home and install a drainfield. The soils do not perk well on the east side, which is another reason why the drainfield is required on the west side of the wetland. The legal access to the site is from Blueberry Hill Drive and no alternate access is available to the western building site from Coyle Road or from the adjacent property owners. Because access is required from Blueberry Hill Road and the drainfield and one of the proposed building sites is situated west of the wetland, a driveway is proposed across the north end of the wetland where it is narrowest. The crossing will require wetland fill and installation of a culvert that will permit continued flow of hydrology from the north into the wetland. The wetland fill will be mitigated in accordance with the Jefferson County Unified Development Code and a Nationwide Permit may be required from the US Army Corps of Engineers. State permits will likely be necessary from both the Washington State Department of Ecology and from the 10 Washington Department of Fish and Wildlife depending on whether they consider the inflow of water from the north a formal stream. Enhancement of existing disturbed wetland is proposed for wetland fill compensation and will be conducted at a 4: 1 ratio on the east side of the wetland where it is most disturbed, Buffer enhancement will also be conducted along the driveway to provide a vegetative barrier between the driving surface and the wetland, .A mitigation plan will be prepared once the jurisdictional determination has been made by the regulatory agencies, The wetland fill will be mitigated on site and will be done through enhancement of the wetland at the 4: 1 ratio so there will be no loss of wetland function, There will be a slight reduction in wetland acreage but not to a degree that would affect the functions provided by the wetland system, The enhancement of wetland will actually improve upon the degraded communities and likely improve some of the functions. A culvert will be placed beneath the road to ensure hydrologic. flow continues through this drainage system from the swale to the north. The home, drainfield and other proposed features have been positioned so that they will be outside the required 100 foot Category II wetland buffer. The buffer is in very early stages of recovery following the clearing so there is a high percentage of low and high shrubs beginning to inhabit the wetland along with young trees that provide a very thick vegetation barrier between the wetland and the future buildings. This vegetation is more than sufficient to protect the wetland and its inhabitants from most noise and light generated on the developed areas, There should be no adverse water quality impacts as there is good vegetation in the buffer that can trap sediments and pollutants and keep them from having a negative impact on the quality of water within the wetland. Runoff generated on the driveway will be the only concern but this can be allayed by proposing a shallow ditch or swale that will prevent driveway water from entering the wetland direction. The ditch can send water away from the wetland and drain into a wide area of buffer where it can sheet flow through the buffer and pollutants/sediments trapped before the water enters the wetland. Flood water storage functions should not be affected for the same basic reasons-there is good buffer vegetation that can slow the flow of water and allow some to percolate into the permeable upland soils, There are also likely small depressions in the upland (behind old logs and living trees) where water can be stored rather than being allowed to drain directly into the wetland, SUMMARY The delineated wetland discussed in this report is located at 345 Blueberry Hill Drive (Tax Parcel No. 601-105-001) in the Quilcene area of Jefferson County, Washington. The site is approximately 5 acres in size and legally referred to as Lot 1 of Blueberry Hill Large Lot Subdivision. A single family home, satellite bedroom building and pole barn are proposed for construction on this parcel. The drainfield is proposed on the west side where it can be outside the 100 foot well radius and where the soils perk the best. A Category II forested and emergent wetland is situated across the east half of the property 11 and a driveway from Blueberry Hill Drive will cross the north end of the wetland to achieve access to the western building site access. No other access is possible since the neighbors will not permit access from their driveways and no access will be permitted from Coyle Road by Jefferson County because of site distance issues. A Nationwide Permit may be required from the US Army Corps of Engineers for the driveway crossing with state permits possibly required from the Washington Departments of Ecology and Fish/Wildlife. This report has been prepared to initiate permit proceedings so that jurisdictional issues are known before a mitigation plan is prepared, The wetland and upland portions of the parcel were cleared about 10 years ago and both areas have begun vegetation recovery. The vegetation is. dominated by native species including hardhack, slough sedge and salal in the wetland and by a mixture of red alder, western red cedar, western hemlock, Douglas fir and madrona trees in the upland areas. The upland shrub layer is fairly thickly vegetated with salal, evergreen huckleberry, and sword fern with lower percentages of slough sedge. The wetland is fed by surface water from the surrounding uplands as well as a seasonal perched water table and a small swale entering the northern tip of the wetland. The wetland meets the criteria for a Category II system because it is moderate in size and contains at least 2 vegetation communities. It does not appear to act as a corridor to other habitat areas but it is presumed to export organic matter to a stream on a seasonal basis and it has buffers of about 100 feet around 50% of its perimeter. The wetland rates Low.to Moderate-High for functional values, rating highest for water quality protection and storm/flood water storage. The wetland rates lowest for groundwater associations and has moderate value for wildlife usage as the community appears mainly valuable to local small birds, mammals and amphibians. There does not appear to be habitat available for priority species. Category II wetlands require 100 foot buffers according to the Jefferson County Unified Development Code and a 4: 1 enhancement to impacted wetland ratio is required as compensation for wetland fill. The proposed buildings are outside the required 100 foot buffer and the wetland impacted by the driveway fill will be mitigated through wetland enhancement mostly on the east side of the wetland. LIMITATIONS This report has been prepared for Horizon Holdings (a Family Limited Partnership) and Ken Shock. It is important to acknowledge that definition of plant community boundaries is not an exact science. Different agencies and individuals may often disagree on exact boundaries and/or plant community classifications. It is the responsibility of the various resource agencies that regulate development activities in wetlands to make the final determination of wetland boundaries. Therefore, the information presented in this report should be reviewed by the appropriate regulatory agencies prior to detailed site planning and/or construction activities. 12 Given the constraints of schedules and scope of work, Wiltermood Associates warrants that the work performed is in accordance with the technical guidelines and criteria in effect at the time this report was prepared, The results and recommendations of this report represent professional opinion based upon the information provided by the client, the client's consultants, and that gathered through the course of this wetland study.

Por further information, see pages 39 and 40 of the soil survey. Sinclair Series The Sinclair series consists of moderately well drained soils that have a very slowly permeable cemented layer at a depth of 20 to 40 inches. These soils formed in glacial till on glacial terraces. Slopes range from 0 to 30 percent and elevation ranges from 100 to 800 feet. Vegetation is mainly Douglas-fir, western redcedar, red alder, willow, rhododendron, and sala!. Annual precipitation ranges from 25 to 45 inches and the average annual air temperature is 490P. The above 320P growing season ranges from 180 to 210 days, and the above 290P growing season ranges from 210 to 240 days, These soils are associated with Alderwood, Cathcart, Beausite, Everett, Hoypus, Indianola, Kitsap, Olete, Quilcene, and Whidbey soils. In a representative profile in a wooded area, the upper 2 inches of the soil is grayish-brown fine sandy loam, Below this to a depth of 8 inches, is dark-brown gravelly sandy loam, Beneath this, and extending to a depth of 25 inches, is dark-brown and dark yellowish-brown gravelly sandy loam. Below a depth of 25 inches is a dark grayish-brown cemented layer. Glacial cobbles and stones are present throughout the profile, Most of the acreage of this soil is used for production of trees, and most areas are wooded. Less than 20 percent of the acreage has been cleared and is used for small ranches and rural homesites, Some pasture, hay, berries and vegetables are grown in cleared areas, for personal use. Sinclair gravelly sandy loam, 0 to 15 percent slopes (SnC).- This nearly level to rolling soil is on glacial terraces. Most slopes range from 5 to 10 percent. This soil is moderately well drained. Permeability is moderately rapid above the cemented layer. Roots penetrate to the cemented layer, This soil holds about 2 to 4 inches of water available for plants. Runoff is slow to medium, and the hazard of water erosion is slight to moderate. A perched water table is on top of the cemented layer during the rainy season. APPENDIX C: WETLAND DETERMINATION/DELINEATION METHODOLOGY The definition for wetland established by the U.S. Army Corps of Engineers (COE) was used to determine the presence and extent of wetlands on this parcel. Section 404 of the Clean Water Act (1972) states that wetlands are: "Those areas that are inundated or saturated by surface or groundwater at a frequency and duration sufficient to support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands generally include swamps, marshes, bogs, and similar areas." This criteria is based on the Department of Ecology Washington State Wetland Identification and and Delineation Manual, the 1987 Corps of Engineers (COE) Wetland Delineation Manual and the 1989 Federal Interagency Committee for Wetland Delineation (FICWD). This committee included representatives from the COE, U.S. Fish and Wildlife Service, Environmental Protection Agency, and Soil Conservation Service, to establish technical procedures and guidelines for wetland determination and delineation. These guidelines as set forth in both delineation manuals requires that three technical criterion: (1) hydrophytic vegetation, (2) hydric soils, and (3) wetland hydrology must all be met for an area to be identified as wetland. A general summary of these criterion or parameters as defined within the COE and FICWD manuals include: Hydrophytic Vegetation Criterion: This criterion is met when, under normal circumstances 50 percent or more of the composition of the dominant species from all strata are obligate wetland (OBL), facultative wetland (FACW), and/or facultative (FAC). Hydric Soil Criterion: This criterion is met for any area having soils that are saturated, flooded, or ponded long enough during the growing season to develop anaerobic conditions in the upper part (USDA Soil Conservation Service, 1987). Wetland Hydrology Criterion: This criterion is met for any area having permanent or periodic inundation, or soil saturation to the surface, at least seasonally. These three criterion are the basis for all field work and wetland delineation performed on this parcel. The specific methodology used is outlined in the next section. WETLAND DELINEATION METHODOLOGY The wetland delineation followed the Routine On-site and Intermediate Determination Methods as outlined in each manual. A summary of this method includes: Plant Community Assessment. The entire project site was initially walked to identify the plant community types present. This provided a rough picture of the type and extent of wetland(s) which exist on site. Also observed and noted were topographical features, 1 hydrologic flow patterns, and any significantly disturbed areas, It was then determined whether normal environmental conditions were present, or human modifications had occurred to the wetland. Selection of Sample Area(s). A series of sample areas or points were selected and flagged to best characterize the plant communities of suspected wetland and non-wetland areas. The approximate location of these flagged sample points were noted on a map of the project site for subsequent survey. Characterization of Plant Communities. At each sample point the dominant plant species within the tree, shrub, and herb stratum were identified and noted on a data form. Species were identified and noted according to Flora of the Pacific Northwest (Hitchcock & Cronquist, 1973). The estimated percent areal cover and the indicator status (as listed in the National List of Plant Species that Occur in Wetlands: 1988, Washington) were also noted on the data form. It was then determined whether the hydrophytic vegetation criteria was met. When 50 % or more of the dominant species have an indicator status ofOBL, FACW, or FAC, the vegetation is considered hydrophytic. Characterization of Soils. At each sample point, a hole 16 to 18 inches in depth was dug using a spade (an existing soil perk hole was used if available). Soil characteristics (matrix color, mottles, etc.) were examined and noted. It was then determined whether the hydric soil criterion was met. Hydric soil criterion is outlined on page 6 of the FICWD manual and pages 26 to 34 of the COE manual. Determination of Hydrology Criterion. At each sample point the presence of inundation by water, soil saturation by water, or other hydrologic field indicators was noted. It was then determined whether the wetland hydrology criterion was met. Wetland Determination. The completed data forms were then examined for each selected sample point within the plant communities. Each plant community meeting the hydrophytic vegetation, hydric soil, and wetland hydrology criteria was considered wetland, Data forms are numbered correspondingly to the sample points located on the final survey drawing. DETERMINATION OF WETLAND-NONWETLAND BOUNDARY After completing the determination method summarized above, the actual boundary between wetland and non-wetland was delineated. This delineation was completed by: 1, recognizing obvious wetland and non-wetland areas, 2. identification of transitional areas between the two areas, 3. [mal determination of the boundary by further sampling of vegetation, soils, and hydrology. The wetland Boundary was then flagged with numbered orange flags with WB (Wetland Boundary) written on them. The approximate location of these flags was then noted. on a map, if available, for subsequent survey. * Important Note: The exact location of the boundary between wetland and non-wetland areas may be difficult to determine, especially if transition areas are more gradual. In cases such as this the wetland boundary is determined, after further sampling, by using the best possible professional judgment. 2 APPENDIX D DEFINITION OF PLANT INDICATOR STATUS The following plant indicator status categories and their symbols are derived from the Wetland Plant List, Northwest Region, USFWS, Washington, D.C. (Reed, 1988) Symbol Defmition of Plant Indicator Status OBL Obligate wetland plants are nearly always found in wetlands (estimated probability 99 % or more) FACW Facultative wetland plants usually found in wetlands (estimated probability 67-99 % ) FAC Facultative plants are equally likely in wetlands and uplands (estimated probability 34-66 % ) FACU Facultative upland plants usually in uplands (estimated probability 67-99 % ) UPL Upland plants are nearly always in uplands (estimated probability 99 % or more) NI Not indicated plant species are not determined due to lack of sufficient information NL Not listed in the "National List of Plant Species that Occur in Wetlands" indicating the lack of information for this species. Note: The "National List of Plant species that Occur in Wetlands" uses a plus ( +) or minus (-) sign to specify a higher or lower portion of a particular wetland indicator frequency for the three facultative-type indicators...).

The overall goal of mitigation shall be no net loss of wetland function, value, and acreage, (1) Mitigation Sequence. Mitigation includes avoiding, minimizing, or compensating for adverse impacts to regulated wetlands or their buffers. When a proposed use or development activity poses potentially significant adverse impacts to a regulated wetland or its buffer, the preferred sequence of mitigation as defined below shall be followed unless the applicant demonstrates that an overriding public benefit would warrant an exception to this preferred sequence. (a) Avoiding the impact altogether by not taking a certain action or parts of actions on that portion of the site which contains the regulated wetland or its buffer; (b) Minimizing impacts by limiting the degree or magnitude of the action and its implementation; (c) Rectifying the impact by repairing, rehabilitating, or restoring the affected environment; (d) Reducing or eliminating the impact over time by preservation and maintenance operations during the life of the action; or ( e) Compensating for the impact by replacing, enhancing, or providing substitute resources or environments. (2) Compensatory Mitigation - General Requirements. As a condition of any permit or other approval allowing alteration which results in the loss or degradation of regulated wetlands, or as an enforcement action pursuant to Chapter 18.50 leC, compensatory mitigation shall be required to offset impacts resulting from the actions of the applicant or any code violator. (a) Except persons exempt under this article, any person who alters or proposes to alter regulated wetlands shall restore or create areas of wetland equivalent to or larger than those altered in order to compensate for wetland losses. The following Table 3-5 specifies the ratios that apply to creation or restoration which is in-kind, on-site, and is accomplished prior to or concurrently with alteration: Table 3-5.

(d) Compensatory mitigation must be conducted on property which will be protected and managed to avoid further development or degradation. The applicant or code violator must provide for long-term preservation of the compensation area. (e) The applicant shall demonstrate sufficient scientific expertise, supervisory capability, and financial resources, including bonding, to carry out the project. The applicant must demonstrate the capability for monitoring the site and making corrections if the project fails to meet projected goals. (3) Compensatory Mitigation - Type, Location, and Timing. (a) Priority will be given to in-kind, on-site compensation if feasible and if the wetland to be lost has a moderate to high functional value. (b) When the wetland to be impacted is of a limited functional value and is degraded, compensation may be of the wetland community type most likely to succeed with the highest functional value possible. (c) Out-of-kind compensation may be allowed when out-of-kind replacement will best meet identified goals (for example, replacement of historically diminished wetland types). Where out-of-kind replacement is accepted, greater acreage replacement ratios may be required to compensate for lost functional values. (d) Off-site compensation can be allowed only if: (i) On-site compensation is not feasible due to hydrology, soils, waves, or other factors; (ii) On-site compensation is not practical due to probable adverse impacts from surrounding land uses; (iii) Potential functional values at the site of the proposed restoration are significantly greater than the lost wetland functional values; or (iv) Off-site, compensation will be conducted in accordance with subsection (4) of this section (Cooperative Compensation Projects). (e) Except in the case of cooperative compensation projects, off-site compensation must occur within the same watershed where the wetland loss occurs; provided, that Category IV wetlands may be replaced outside of the watershed if there is no reasonable technical alternative. The stormwater storage function provided by Category IV wetlands must be provided for within the design of the development project. (f) Except in the case of cooperative compensation projects, in selecting compensation sites. applicants must pursue locations in the following order of preference: (i) Filled, drained, or cleared sites which were formerly wetlands and where appropriate hydrology exists; and (ii) Upland sites, adjacent to wetlands, if the upland is significantly disturbed and does not contain a mature forested or shrub community of native species, and where the appropriate natural hydrology exists. (g) Construction of compensation projects must be timed to reduce impacts to existing wildlife and flora. Construction must be timed to assure that grading and soil movement occurs during the dry season. Planting of vegetation must be specifically timed to the needs ofthe target species. (4) Cooperative Compensation Projects. The county may encourage, facilitate, and approve cooperative projects where one or more applicants, or an organization with demonstrated capability, may undertake a compensation project if it is demonstrated that: (a) Creation of one or several larger wetlands may be preferable to many small wetlands; (b) The group demonstrates the organizational and fiscal capability to act cooperatively; (c) The group demonstrates that long term management of the compensation area can and will be provided; and (d) There is a clear potential for success of the proposed compensation at the identified compensation site. Conducting compensation as part of a cooperative process does not reduce or eliminate the required replacement ratios outlined in this article. fOrd. 5-03 92; Ord. 11-009 3.6.9(f)] Article VI-J.

(Ord. 4-02 9 2; Ord. 11-009 3.6.l0(a)] APPENDIX F Wetland Functions and Values Information It is important that those involved in wetland regulation and management understand their functions and values. Knowledge of these roles can be a key factor in the design and implementation of wetland inventories. Not all wetlands provide each function or value nor do they provide them to the same degree. Variations occur because of wetland type and characteristics, as well as regional and local influences. Some local governments try to distinguish how functions and values relate to their community and region. The following is a brief summary . Water Supply With the growth of urban centers and dwindling water supplies, wetlands are increasingly important as.a source of surface and ground water. They can function as recharge areas where water soaks into the soils, replenishing ground water supplies. Wetlands are also areas where ground water moves to the surface through springs and seepage, often collecting in pools and ponds, and supplying critical reserves during periods of drought, Flood Control Wetlands are valuable in reducing the impact of flooding. They have the ability to store and slow the flow of water from upland run-off. If a wetland is associated with a river in a flat valley, the wetland and its vegetation reduces the height and velocity of flood peaks. Some wetland soils can store large amounts of floodwater and gradually release them downstream. Construction in flood plain wetlands causes increase flood heights and rates, and an associated increase in flood damage. Erosion Control Vegetated wetlands serve as natural buffers from the effects of tides, waves, wind and river currents. They dissipate the energy of these erosive forces. The fibrous root systems of wetland plants bind and stabilize banks, protecting the shoreline from erosion. On the coast, they can limit wave generation, slow and absorb the impacts of wave energy, and thereby protect inland areas from storm damage. Construction of bulkheads, rip-rap, and other banked hardening stabilization techniques simply transfer the erosive energy to neighboring areas. Pollution and Sediment Control Wetlands protect and improve the quality of surface and ground waters by removing sediments, nutrients, heavy metals, and hazardous chemicals. Wetlands vegetation filters particulate matter from the water. When moving water comes into contact with vegetation, its flow is slowed and sediment falls out of suspension. The root systems trap the sediment, reducing siltation in downstream water bodies. Substances such as nutrients, pathogens, and many chemicals are often bound to the surface of sediment particles, Thus, sedimentation reduces both organic and inorganic pollutants. These pollutants may be released when wetland soils are disturbed. Wetland vascular plants and algae also absorb nutrients and chemicals, The micro-organisms utilize dissolved nutrients and break down organic matter. Research is underway to determine the impacts of utilizing wetlands as tertiary waste treatment facilities. Wildlife Habitat Wetlands, the interface between land and water, are among the richest wildlife habitats 'in the world. They provide the conditions essential for the breeding, nesting, feeding, and protection for many species of waterfowl, mammals, reptiles, and amphibians. These conditions include abundant water, diverse and rich vegetation, and adequate cover. Many of these species are "obligates" or dependent upon the wetland for their survival. Some such as the beaver spend their entire lifetimes in the wetland environment. Others like the salmon inhabit it for shorter, but critical, parts of their life cycle. Numerous species (such as deer and raccoon) depend on wetlands as a source of drinking water, food, and winter cover. Wetlands are as critical to the needs of these species as they are to those that depend solely on wetland habitat. Though many waterfowl nest primarily in northern freshwater wetlands, they use wetlands through out the county while migrating and for over-wintering. Birds such as herons, egrets, rails and harriers depend upon wetlands for their survival. Both salt and freshwater wetlands are important spawning, nursery, feeding, and wintering areas for sport and commercial fish and shellfish. Wetlands also support many endangered plant and animal species. Although wetlands constitut~ only 5 per cent of the nation's lands, close the 35 per cent of all rare and endangered animal species are dependent upon them. (McMillan, A. 1986) .' Food Web Productivity Wetlands play an important part in the food web. Coastal wetlands are among the most productive areas in the world. Solar energy is utilized by wetland plants to produce hundreds of pounds of nutrients per acre of salt marsh annually, The vegetation dies, decays, and is broken down to form a nutrient-rich "soup" called detritus. This rich food source is converted by micro-organisms into basic nutrients and elements for use by vascular plants and phytoplankton (minute floating plant life). The phytoplankton are consumed by zooplankton (minute floating animal life). the detritus and plankton's are carried into tidal creeks, and bays and are consumed by invertebrates such as oysters, shrimp and crabs. they in turn are preyed upon by other animals including humans. It has been estimated that 90 per cent of the important commercial marine species either spend their entire lives in estuarine wetlands or require estuaries as nursery grounds (Kusler, J. 1983). Freshwater wetlands also provide food, habitat, and spawning grounds for many other species of fish. Education and Research Coastal and inland wetlands provide unique opportunities for education and scientific research. Due to the land-water interface, diversity of vegetation, topography, and the resulting varied habitats, wetlands are ideal for studying plant and animal life. Because ecological relationships are easily observed, they are excellent locations for teaching environmental science. The complex ecological relationships of wetland systems make them valuable areas for scientific research as well. Recreation and Aesthetic Values Wetlands are areas not only of great diversity but also of great beauty. They provide open space and contrast for both visual and recreational enjoyment, especially valuable in urban areas. Visitors include photographers, bird watchers, hikers, boaters, hunters, fishers and natural history enthusiasts, Appreciation and use of wetlands as a recreational resource is steadily increasing on both a national and state-wide basis. National, wetland-dependent waterfowl are hunted by over 2 million hunters. Nisqually National wildlife Refuge, near Olympia, Washington has had a 300 percent increase on visitor use since 1977.
