Location: Study site is located approximately between Howard Street and Rainier Street easements, north of Discovery Road and south of 20th Street in Port Townsend; within the NE '/4 of Section 9, Township 18N, Range 2W. Wetland delineation was carried out by Lisa Palazzi, (ARCPACS certified soils scientist and SWS certified wetlands scientist) and Pesha Klein (SWS certified wetlands scientist) on October 6, 1997. The purpose ofthis report is to describe results ofthat delineation and to provide a site work history for general reference. WETLAND REGULATIONS The following overview of wetland regulations is provided for your information. It is intended to provide general information and a framework to help you be aware of situations of overlapping authority. Local Wetland Regulations: Cily of Port Townsend To qualify as a regulated wetland. in Port Townsend, an area must first meet criteria defined in the 1989 Federal Manual for Identifying and Delineating Jurisdictional Wetlands. Those criteria require that an area must predominantly support wetland vegetation, must have hydric soils, and must have wetland hydrology characteristics defined for the on site soil type -- in this case, evidence or observation of a long - duration water table at 12 inches or less depth. If the area meets all the criteria listed above, it must also meet certain size requirements to be regulated by the City. The minimum regulatory wetland sizes in Port Townsend are as follows: Page 1 There is no size limit for Category I wetlands. All Category II and III wetlands must be greater than 5000 square feet. All Category N wetlands must be greater than 10,000 square feet. The wetland edge is located by evaluating the presence or absence of the three parameters, then flagged in the field, often for a subsequent survey, but sometimes just for purposes of onsite measurement. Once identified as regulated wetland, the wetland is "rated" using the 1994 edition of the Western Washington Wetlands Rating System. The rating system combines a series of questions and a point system to determine the specific value ofthe individual wetland. Depending on site specific, pre- development wetland vegetation, soils, hydrology and buffer characteristics, the wetland has greater or lesser value and so is afforded varying levels of protection in the form ofwetland buffers. The higher the rating and the higher the intensity of development, the greater the buffer, ranging from a minimum of 25 feet for low quality, small wetlands up to a maximum of 1.50 feet for the highest quality, or rare wetlands. The area within the wetland buffers is generally considered unavailable for development, unless there is no reasonable alternative to a proposed activity. IN that case, the development may be allowed, but only with appropriate mitigation. Federal Regulation s: Army Corps of Engineers Any direct impacts to a wetland are regulated by the Army Corps ofEngineers (COE). The COE regulates wetlands of any size,. Le., there is no minimum size for a federal jurisdictional wetland. Furthermore, the COE must be notified of all impacts to wetlands. There are about 40 Nationwide Permits thafdefine certain allowed impacts to wetlands. As a rule, the COE should be contacted prior to the impacts, and the proposed activity should be described. The COE will let the applicant know if one ofthe Nationwide Permits fits, or if no permit is required. If no permit is required, they will still require that a standard report be filled out and submitted that describes the activity in detail. If they are not notified, the action will be treated as a violation. Impacts of 0.1 to 2 acres are typically regulated under one of the.Nationwide. Permits with concurrent permit review by the COE and the Washington State Department of Ecology. Impacts not covered by one of the Nationwide Permits will require an individual permit. For an individual permit, a detailed assessment ofthe project will be required, including an alternatives analysis and detailed justification of the proposed impacts with no guarantee ofauthorization to carry out the proposed wetland impact. Other Regulatoa State Agencies Other potentially involved agencies include (but are not limited to) the Washington State Department of Fish and Wildlife (WDFW), and the Washington State Department ofNatural Resources (DNR) Natural Heritage Program. Page 2 General History and Wetland Description The study site is a Palustrine Forested (PFO), Palustrine Scrub -Shrub (PSS), Palustrine Emergent PENT) wetland complex located in the headwaters ofBasin l l (as defined on recent City maps) more or less between Howard Street and Rainier Street easements, north of Discovery Road and south ofwhat would be the 19th Street easement. The northwest end of the wetland is located at the northeast corner ofthe Nancy Scott property, near the intersection of the semi - developed . Rainier Street easement and the undeveloped 18th Street easement. The wetland drains from that point in a south - southeasterly direction to where it eventually backs up against Discovery Road between the Eddy Street easement and Rainier Street easement. After it crosses Discovery Road, the water drains south through a relatively new subdivision south ofDiscovery Road, then flows either south through a business park (Basin 16) , or east through a series of wetland swales (Basin 11), with the direction of flow dependent on subsurface drainage patterns and on how the subdivision drainage was diverted during construction. The main body of the wetland north ofDiscovery Road ranges fromjust a few feet wide to greater than 100 feet wide in some areas with the heart of the wetland dominated by herbaceous species such as slough sedge (Carex obnupta) or shrub species such as hardback (Spirea douglasii). The edges of the wetland are predominantly forested or shrubby, with western redcedar (Thuja plicata) and a variety of willows (Salix spp.) being the dominant species. Just outside the wetland boundary, the vegetation community changes relatively rapidly to Douglas -fir, Pacific madrone, and salal -- distinctly upland vegetation. In wetter than average years, due to relatively low relief and minor topographic difference between the wetland and adjacent upland areas, this wetland can expand a considerable distance outside ofits jurisdictional boundaries and flood adjacent buffer and upland areas. For that , reason,. it is highly recommended that the City keep an ongoing record (annual sampling) ofthe periodic flood zones in order to adequately identify those areas that would be regulated as frequently flooded areas or drainage corridors. It may also provide a record of wetland expansion over time as the surrounding area develops and more water is sent to the wetlands. In any case, it is to the City's advantage to have this record to protect both its own and its citizens long -term interests. The main wetland complex was formally delineated in the past (in about 1994 -95), but the flag. locations were not surveyed, with the exception of flags surrounding the far northwestern end of the wetlands and down the western edge to just south ofthe driveway access to Nancy Scott's property. It should be noted that in the process of that delineation, a series of three flags were used in one area to imply a subsurface hydrologic connection across an upland area between two parts of the wetland. As a result, the surveyed points make it appear as though the edge is continuous when in fact, there is an upland crossing about 30 -40 feet wide at about Flags 22 -24 numbering from the old delineation). That error should be corrected on the surveyed map. In addition, there were several small wetland pockets north ofthe main system that may be Page 3 hydrologically connected to this system via subsurface flow, but not over the surface in most years. All were individually of less than regulatory size, and outside the scope of the original work which was focused on potential impacts to the south, so were not delineated. The purpose of this work is to verify the previously delineated and surveyed wetland boundary along the western edge ofthe wetland where buffer setbacks may impact the CT pipeline route i.e., the portion of the boundary that was already surveyed). In addition, the regulatory status of a wet drainage area crossing Rainier approximately between the 12th and 1 lth Street easements to the south was assessed. The flagging around the rest ofthe wetland perimeter was not evaluated as it was outside of any area of potential impact from the CT pipeline project. To save on budget, no wetland report was prepared at the time ofthe earlier delineation, at the request of the City. This report provides documentation of work carried out both during this recent field visit and to a limited degree, during the past delineation. It can be amended as needed in the future as the balance of the wetland boundary is delineated and surveyed. Description of the Three Parameter Wetland Criteria As mentioned above, in order to be regulated as a wetland, the area in question must have hydric soils, hydrophytic vegetation and evidence of a long duration (more than two weeks at a time) water table that persists into the growing season in most years at 12 inches or less. The sections below describe the wetland soils, vegetation and hydrology. Soils According to the Jefferson County Soil Survey, the following soil series are mapped. on or near the site: the Clallam gravelly sandy loam, 0 -15% slopes (classified as a loamy - skeletal, mixed, mesic Entic Durochrept'). The Jefferson County Soil Survey is a Level 3 survey -- meaning that it is not as detailed as the average soil survey in Washington State. So the map units tend to be very general with many inclusions, and forested areas tend to be more poorly mapped than cleared areas. The Clallam map units in Port Townsend commonly contain wetland inclusions. For your information, standard characteristics of the mapped soil series are described in APPENDIX 1. Please note that the SCS soil series maps and descriptions characterize erected characteristics in only the.top 60 -100 inches of soil. Furthermore, the map units can have extensive inclusions of other soil types; and in some rare cases, can be entirely in error. The soils observed in the wetlands were what -- in a more detailed soil survey -- would probably Loamy- skeletal, mixed, mesic Entic Durochrept, generally meaning the soil has minimal horizon development (ept and entic), has a pale- colored, low base saturation surface horizon (ochr), has an silicate-cemented subsurface layer (dur), has a mesic temperature regime (mean annual temperature ranges from 8° to 15° C (47° - 59° F), has no specific mineralogic source (mixed), texture ofthe fine fraction is loam and coarse fragment content is greater than 35% (loamy-skeletal). Page 4 be mapped as Swantown series, having a gravelly sandy loam surface overlying a shallow cemented hardpan, and having a seasonal water table within 6 -12 inches of the surface. The surface mineral soils were very dark - colored (IOYR2 /1) with an accumulation of organic materials over the mineral surface. A cemented, mottled (2.5Y4/6 color) glacial till substrate with a depleted matrix (2.5Y5/2 color) was generally encountered within 10 -15 inches ofthe soil surface. The soils within the top few inches of the till were slightly weathered and more permeable than the underlying, more strongly cemented layers. As a result, water tends to perch both above and within the top of the till. But very little water is expected to infiltrate more than a few inches into the till surface. The combination of the unusually shallow till and minimal infiltration potential causes the soils to have very little storage capacity, and consequently makes ponding and flooding potential quite high following even slightly above normal precipitation. The upland soils adjacent to the wetlands were Clallam series, having a surface duff about 3 -4 inches thick overlying a gravelly sandy loam surface soils with cemented tills at 10 -20 inches. The soil colors were similar to those in the wetland, but slightly yellower and with few mottles. The Ciallarn soils tend to have a thin saturated zone above the till even in upland positions. But soil colors (2.5Y5/3 matrix color with 2.5Y4/4 mottles) indicate that the water does not persist as long as it does in the lower elevation landscape positions. Vegetation The predominant vegetation in the middle of the wetland was either slough sedge or hardhack. The wetland edges were dominated with a variety of tree and shrub species -- mostly willow, spirea, and wild rose. This-pattern is typical of many ofthe larger Port Townsend wetlands. Species are listed below with jurisdictional status) The upland vegetation in areas immediately adjacent to the wetlands included some of the wetland species, but also Douglas -fir, big leaf maple, wild filbert, salal, sword fern, Himalaya blackberry, and trailing blackberry.

Page 6 Rubus ursinus (RLT R) trailing blackberry FACU Pteridium aquilinum (PTAQ) lady fern FACW Hydrology The source of hydrology appears to be seasonal stormwater that infiltrates, then perches in the soil above the shallow till surface, then, once the soil's storage capacity is exhausted, begins to drain across the till surface to the south following the broad, flat swale that defines the wetland. There was no evidence of spring activity, and these wetlands tend to dry up during the summer months, implying a seasonal water source. There was ample evidence of surface water from this past winter well outside the jurisdictional wetland boundary -- flood rack in bushes, water - stained leaves, flattened grasses parallel to the direction of flow. The edge ofthat surface water was surveyed at several points along the wetland edge during last winter. That flood record should be maintained and will be of great use when planning for development in the surrounding area. In most years, the wetland is expected to have some areas of open water in the middle, and saturated soils along the edges with periodic surface flow during and following extended storms. During extended storms, or in years with even slightly above average rainfall, due to the soils being very shallow and having no effective storage volume once saturated, there is a very high potential for the water table to rise and expand outside the jurisdictional wetland edge. The degree of expansion will be directly related to the change in elevation at the wetland edge. For example, in very flat areas, a six -inch rise in the water table could result in the wetland expanding out 50 -100+ feet beyond the jurisdictional edge. On the other hand, if the wetland is incised in a deep channel, the water table could rise several feet without expanding more than,a few feet from. the edge. The flood hazard area around the wetland can be defined to some degree by interpreting topography and drawing flood lines at 0.5 -1 foot elevation increments around the surveyed edge. A hydrologic basin analysis could then be used to determine potential volumes that could concentrate in the wetland as a result from storms of various intensities, assuming no soil storage in the wetland portion of the basin. Wetland Classification and Rating The results of the Field rating (form is provided in Appendix III) indicate that the on -site wetland is a Category II system due primarily to being having a variety of wetland classes and plant species, moderately good buffers around most of the perimeter, and a connection to significant upland and riparian habitat (forested lands around the wetland). It does not merit rating as Category I system due to previous logging and draining impacts in some areas. Class II wetlands are given 100 feet wide standard buffers in the Port Townsend. Page 7 Wetlands Regulatory Issues If there are any impacts to wetlands or the standard buffers as a result of this project, they must be permitted and mitigated for to some degree with the primary jurisdictional agency being the City of Port Townsend for both buffer and wetland impacts, and the Army Corps of Engineers for wetland impacts only. The CT pipeline project proposes some buffer impacts along the northwestern edge. Currently, no impacts are proposed in the wetlands. Therefore, the primary regulatory authority is the City. I hope this report provides adequate information for you to proceed with project planning.

They are usually found on uplands, slopes ranging from 0-30 %. The surface soils are generally grayish -brown to. dark grayish -brown gravelly sandy loams. They have a weakly cemented glacial till layer at 20 -40 inches depth that will restrict vertical soil percolation to some degree. Average soil permeability is expected to be moderate (0.6 -2 inches per hour) above the cemented till and very slow (less than 0.06 inches per hour) in the till layer. A seasonal perched water table is expected above the till. The soil above the till is expected to be saturated periodically during the rainy season and the majority of soil water will percolate laterally. The Clallam soils originally developed under a forest, but more than half of the mapped acreage has been cleared and is now used for pasture, gardens, orchards and homesites. The primary limitations are related to shallow soil depths. Stormwater will percolate into the soil readily in undisturbed areas, but will move laterally across the till layer, surfacing in adjacent drainages and low -lying areas. Septic system design will be limited by minimal soil depths and fluctuating seasonal high water.
