I hired Mike Dawson, a local wetland biologist who has completed the new rating form training, to complete the DOE form. I-Iis score was 41 points or a Category III. wetland. If the wetland unit was shown to have the "opportunity" to reduce flooding his score would have been 51 paints (Categary II). Since this wetland is at the top of a basin I rated it as having this "opportunity" According to the Part Townsend Municipal Code, revised November 2005, all wetlands, Category I, II, III and IV are regulated if they are larger that 1,000 square feet (19.05.110 Critical area 5 Wetlands C. 2.j.

Flint Wetland Delineation And Mitigation Plan Parcel # 964 200 701 (702) June 200b ntr©duction At the request of C.L.Flirlt a wetland delineation was conducted on June l4, 2006. An extension of Deering Wetland (WL #9-1) near the no~hern parcel (964 200 702) was identified during a Level I Wetland Assessment conducted an January 31, 2006. At the time of the original assessment the majority of understory vegetation had been cleared on the northern parcel and along Katherine Street to 29th Street. The large trees were not eut. Due to the identification of the wetland and potential impacts to wetland buffer it was decided by the City that Katherine Street should not extend to 29th Street as per building code requirements. The goal of the wetland delineation is determine the exact edge of the wetland, categorize the wetland according to the recent Department of Ecology Rating form., and measure and mark the buffers. This report includes a mitigation plan to address buffer impacts. Buffer setbacks now impact the designed septic site location on parcel 964 200 702. All the buildings are on parcel 964 200 701 and are well outside wetland buffers. Buffer reductions apply only to the proposed septic system and are therefore within the jurisdiction ofthe Environmental Health Specialist of Jefferson County and the City of Port Townsend.

All wetlands within the City of Port Townsend are subject to requirements outlined in the Code. Land use restrictions will apply to all future developments associated with this parcel. A comprehensive description of methodology used during this delineation is included in the Appendix. The following resources were consulted for this project: Part Townsend Critical Areas Map Wetlands {1995) Aerial Photographs (Soil maps pre-1975 and 2000, included in Appendix} City of Port Townsend's Municipal Code (July 2005) Soil Siuvey of Jefferson County (U.S. Soil Conservation Service 1975} Washington State Wetland identification and Delineation Manual National List of Plant Species That Occur in Wetlands: Northwest (Region 9} Findings The wetland, east of Katherine Street and within a portion of 29`'' Street, has a distinct wetland/upland edge. The plant communities, soil types, and a slight drop in elevation define the delineated edge. 'Fhe north-east corner of lot 964 200 701 is within wetland buffer. This large seasonal wetland has been previously identified and categorized as a Category Il wetland {1994 Palazzi). The new DOE rating form (DOE 04-06-025} was used to rate this wetland which also verified the Category II rating. Category lI wetlands, with a moderate habitat value, have an assigned 100' buffer. This extension of the Deering Wetland was flagged with orange plastic ribbon labeled Wetland Boundary," at points 1 S to 20 feet apart. Flagging is labeled with alphanumeric codes (Al through A4). The data point locations, wetland edges, and buffers are indicated on the Findings Map in the Appendix (Sheet #2}. Soils Jefferson County Soil Survey (page 40) lists soils within the valley as: TuC Tukey gravelly Ioarn and CmC Clallam gravelly sandy loam; neither sail is listed as a hydric soil on the Jefferson County Area I-Iydric Sail Iist (January 1991). A series of unmapped wetlands City of Port Townsend Critical Areas Maps} are located at the top of Basins S and 9. t'hese seasonal wetlands are common and form within the compacted glacial layers of Clallam sail series whenever there are minor drops in elevation. Data Point # 1 is outside the wetland; the soil did qualify as hydric (l OYR 312 with mottles 1 OYR S/4 and 10YR S/2). Data Point #2, within the wetland, has hydric soils, (lOYR 211 1'Iknt.

The wetland soil is nearly black and was moist, indicating high water tables and frequent saturation. Vegetation Bath the wetland and the upland areas consist of a diversify of native plant species. The wetland has a mosaic of plant communities, structural layers, and habitat features. Wetland vegetation consists of spirea, rose, willow, with an understory of sedges. The upland vegetation, within the buffer that has not been cleared, is dominated by Douglas's fr, salal, oceanspray, and elderberry.

Report File Number 200Ci0G E ~10G Hydrology Water only needs io be present 20 days of the growing season (begins early March} for an area to qualify as a wetland. Since this delineation was conducted in mid 3une, well into the growing season, hydrology can be assumed when there is the presence of wetland vegetation that requires frequent saturation (OBL obligate vegetation}. Mitigation Plan The understory along Katherine Street including the wetland buffer was cleared before the wetland was identified. Between the time of the Level I and the wetland delineation, restoration planting was installed within the buffer. The following plants were planted within the impacted buffer; 10 mock orange, 11 Indian plum, 3 Oregon grape, 3 twinberry, S vine maple, l cherry, 1 snowberry. Native understory, including salal, oceanspray, and rose are quickly returning to the impacted areas as well. Invasive weeds were minimal. li is recommended that 30 or more trees and shrub be planted along the impacted areas of Katherine Street and that alI invasive species be weeded when identified. Weedy species include Himalayan blackberry, Scot's broom and thistle. Additional maintenance will include watering planted trees and shrubs through the dry summers. The mitigation area is indicated on the Bindings Map in the Appendix.{Sheet #2}. Performance Standards I'he proposed length of time far mitigation compliance is five years. 'This time period will allow for the planted and volunteer species to become established. Survivorship of tree and shrub species is expected to be 8fl% or greater and will be determined during the monitoring process. The wetland buffer mitigation will be considered successful if 8Q% or greater ofdesirable cover {both planted and volunteers) is achieved and the plants are healthy and vigorous. Monitoring Monitoring should be conducted far S years to ensure the success of the planted species and that performance standards axe met. A monitoring form included with this mitigation plan will 6e used to determine plant survivorship, species density, and general condition of planted species. This information will determine whether plant survivorship and percent cover provided are sufficient to meet the performance standards to mitigate buffer impacts. A sample monitoring form for this project is included in the Appendix. This form should be included with the annual report submitted to the City of Port Townsend Development Services Department, Public Works. Flint Weiland Delineation rutd Mitigation 1'Can 4 Qlyrn~ic Wetlanc! Resources, lnc. Iteporl l~ tie Nnrrtbcr 20060fi3 ~Ofi Summary A Category II wetland was delineated on June 14, 2006 for C.L. Flint. This wetland, with moderate habitat functions, has associated 100-foot buffers. The majority of the wetland buffer was cleared of all understory vegetation prior to the identification of the wetland. To compensate for this buffer violation a mitigation plan and monitoring schedule are included with this report. Revegetation has begun to compensate for the buffer impacts. Over 30 trees and shrubs have already been planted within the buffer with an additiona130 trees and shrubs will be added after the final construction is complete. Due to the presence of an undisturbed tree layer, both planted and native vegetation returning to the site should have high survival rates. Newly planted native species over time will increase the diversity as well as address buffer impacts. Performance standards for the mitigation plan require an 80% cover of desirable species (planted and returning natives} after 5 years. This will be monitored yearly by a professional biologist and a monitoring report will be submitted to the City of Port Townsend Development Services Department annually. The final authority over this wetland determination and mitigation plan rests with the governmental agencies.

Chapter 173-22 of the Washington Administrative Code requires that all wetlands within the State of Washington be delineated using this manual. All critical areas within the City of Port Townsend are regulated according to the Port Townsend Municipal Code Critical Codes Ordinance (N0.2899, July 2005 PTMC). The rnethodoIogy outlined in the Washington State Wetland Identification and Delineation Manual requires examination of the three parameters for a positive wetland determination: hydric soils, hydrophytic vegetation, and hydrology. For an area to qualify as a jurisdictional wetland it must have a positive indicator from ail three parameters. All wetlands identified using this methodology may be federally regulated, regardless of size. Soils A hydric sail is a soil that forms under conditions of saturation, flooding, or panding lasting long enough during the growing season to result in an anaerobic upper layer. lIydric sails favor the growth and regeneration of hydraphytic vegetation. The indicators for this type of soil include low c~roma, mottles, gleying, and high organic content within the upper 32 inches of the sail profile. 1-toles were dug on the site and soil colors (including value and chroma) were recorded in the top 16 inches. Sail colors were analyzed using the Mansell Color Charts (1992). Vegetation Wetland plant species must constitute greater than 51% of the fatal vegetation present to meet the qualifcation as a site dominated by hydrophytic vegetation. Dominance of plant species is determined by calculating actual aerial cover within a 30~foot radius for trees, a 10-foot radius far shrubs, arzd a 6-foot radius for the herbaceous layer at each data paint. Commonly occurring plant species have been rated by the United States Fish and Wildlife Service (USFV+~ National List of Plant Species That C}ccur in Wetlands: Northwest Region 9) as tp their frequency of occurrence in wetlands and non-wetlands. During the fieldwork, each species was recorded and given a rating based on indicator status and percent COVer. Hydrology Wetland hydrology is defned in the Washington State Wetland ldentifcation and Delineation Manual as "areas that are periodically inundated ar have soils saturated to the surface at some time during the growing season." Areas must have seasonally inundated or saturated soil at least 12.5% of the growing season {20 days out of 258 days). The growing season is described in Jefferson County by the Jefferson County soil survey as March 12 to November 25. The growing season can also be defined by soil temperature at 19.7 inches below the soil surface being higher than biological 0 {5°C or 40°F). Indicators of hydrology include visual observation of inundation ar soil saturation, water stained leaves, cracking of the soil surface, and/or sediment deposits. Positive signs of hydrology aze often absent during the summer and fall months but can be inferred if there are positive indicators of hydric soil and hydroghytic vegetation. Classification Wetland categorization was determined using the Washington State Department of Ecology (DOE} Wetland Rating System Revised (Ecology Publication #04-06-025, August 2004), according to type and class ofwetland. The wetland is assigned a numerical value far water quality function, hydrologic function, and habitat function. The total score determines the category of wetland. Wetlands are rated as entire systems and quite often exceed project boundaries. Rafings range from Category I to Category lV; Category I is the highest quaiiiy wetland. Buffers are assigned according to land use and numeric scares. Category 1 wetlands are not replaceable and therefore receives the largest buffers and highest protection. Determining Wetland Edges Wetland edges were determined by establishing pairs of data points: one within the wetland which contains positive indicators of all three of the wetland requirements: soils, hydrology, and vegetation, and another data point outside the wetland, where one ar all of the requirements were not present. The wetland edge is flagged between the pairs of points at intervals of 20 to 40 feet. Wetland Rating Form Western Washington Location: Section:4 Township:30N Name of Rater.

Olympic Weiland Resources, lnc. Dixie Llewellirt, Principal Biologist A portion of the Deering Wetland (associated with Katherine and 29th Street? was recently delineated and mapped. 'The water line would need to crass the buffer of ibis Category II wetland if it were to be sited within Katherine Street to 29th Street. Katherine Street is partially cleared {which includes part of the buffer} but running a water line would add additional impacts to the Category 11 wetland buffer at 29`h Street. Other alternative routes for the water line should be evaluated. The final authority over where utilities are located rest with the City of Port Townsend Public Works. If there are any other question or you need further help please feel free to call. Sincerely, Dixie Llewellin Principal Biologist, Olympic Wetland Resources, Inc.
