Flint Wetland Delineation And Mitigation Plan Parcel # 964 2A0 701 (702) June 2006 Introduction At the request of C.L.Flint a wetland delineation was 6onducted on June 14, 2006. An extension of Deering Wetland (WL #9-1) near the northem parcel (964 200 702) was identified during a Level I Wetland Assessment conducted on 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 296 Street. The large trees were not cut. 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 964200 702. ALI 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 of the Environmental Health Specialist of Jefferson County and the City of Port Townsend. Description of Site . Legal Description: Parcel #964 200 701 (702) Section 4 Township 30N Range I W o Location:2827 Katherine St. (undeveloped) North of Hastings St. and West of Thomas st.. Soils: TuC Tukey gravelly loam and CmC Clallam gravelly sandy loam . Slopes: 0 to 15% slopes A map of the site location and mapped soils is included in the Appendix (Sheet #1). The subject property consists of two parcels (130' X 198' and 100' X 100'). Three building; a house, gtr€e, and out building are under construction and nearly completed on the southern lot (964 2A0 701). These structures are all outside any wetland buffers. Flint Wetland Delineation and Mitigation Plan Report File Number 2006061406 I Olympic Wetland Resources, Inc. Methodology Wetland analysis was conducted using the methodology outlined in the Washington State Rating Systems for Western Washington (2004) and City of Port Townsend's Municipal Code @TMC), Critical Areas Ordinance (NO. 2899, July 2005). 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:o Port Townsend Critical Areas Map Wetlands (1995)o Aerial Photographs (Soil maps pre-1975 and 2000, included in Appendix)o City of Port Townsend's Municipal Code (July 2005)r Soil Survey of Jefferson cowrty (u.S. Soil conservation Service l97s)o Washington State Wetlandldentification and Delineation Manualo National List of Plant Species That Occur in Wetlands: Northwest (Region 9) Findings The wetland, east of Katherine Street and within a portion of 29ft Street, has a distinct wetland/upland edge. The plant communities, soil types, and a slight drop in elevation define the delineated edge. The 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 II wetland (1994Palazzi). The new DOE rating form (DOE 04-06-025) was used to rate this wetland which also verified the Category II rating. Category II 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 15 to 20 feet apart. Flagging is labeled with alphanumeric codes (A1 through A4). The data point locations, wetland edges, and buffers are indicated on the Findings Map in the Appendix (Sheet #2). Sails Jefferson County Soil Survey (page 40) lists soils within the valley as: TuC Tukey gravelly loam and CmC Clallam gravelly sandy loam; neither soil is listed as a hydric soil on the Jefferson County Area Hydric Soil list (January l99l). A series of unmapped wetlands (City of Port Townsend Critical Areas Maps) are located at the top of Basins 5 and 9. These seasonal wetlands are common and form within the compacted glacial layers of Clallam soil series whenever there are minor drops in elevation. Data Point #1 is outside the wetland; the soil did qualifu as hydric (lOYR 3l2withmotrles 10YR 5/4 and IOYR 512). DataPoint #2, within the wetland, has hydric soils, (10YR 2/1 Flint Wetland Delineation and Mitigation Plan Report File Number 2006061406 2 Olympic Wetland Resourceq Inc- and 10YR 4l2wirhmottlesl0YR 3i4). The wetland soil is nearly black and was moist, indicating high water tables and frequent saturation. Vegetation Both the wetland and the upland areas consist of a diversity of native plant species. The wetland has amosaic 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 fir, salal, oceanspray, and elderberry. Below is the list of vegetation identified on site and the assigued indicator status of each specles.

Plants classified according to the Fish and Wildlife Service; 1988,1993 Update Flint Wetland Delineation and Mitigation Plan Report File Number 2006061406 3 Olympic Wetland Resources, Inc. Hydrologt Water only needs to be present 20 days ofthe growing season (begins early March) for an area to qualiff as a wetland. Since this delineation was conducted in mid June, well into the growing season, hydrolory can be assumed when there is the presence of wetland vegetation that requires frequent saturation (OBL obligate vegetation). Mitigation PIan The understory along Katherine Sheet 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; l0 mock orange, 11 Indian plum, 3 oregon grape, 3 twinberry, 5 vine maple, I cherry, I snowberry. Native understory, including salal, oceanspray, and rose are quickly returning to the impacted areas as well. Invasive weeds were minimal. It is recommended that 30 or more trees and shrub be planted along the impacted areas of Katherine Street and that all invasive species be weeded when identified. Weedy species include Himalayan blackberry, Scot's broom and thistle. Additional maintenance wilt include watering planted trees and shrubs through the dry summers. The mitigation area is indicated on the Findings Map in the Appendix (Sheet #2). Performance Standards The proposed length of time for mitigation compliance is five years- This time period witl allow for the planted and volunteer species to become established. Survivorship of tree and shrub species is expected to be 80% or greater and will be determined during the monitoring process. The wetland buffer mitigation will be considered successful if 80% or greater of desirable cover (both planted and volunteers) is achieved and the plants are healthy and vigorous. Monitoring Monitoring should be conducted for 5 years to ensure the success of the planted species and that performance standards are met. A monitoring form included with this mitigation plan will be 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 sufftcient 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 Wetland Delineation and Mitigation Plan Report File Number 2006061406 4 Olympic Wetland Resources, Inc. Summa A II was delineated on June 14,2006 for C.L. Flint. This wetland, with moderate 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 plarited within the buffer with an additional 30 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 retuming 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 govemmental agencies.

Chapter 173-22ofthe Washington Adminisrative Code requires that all wetlands within the State of Washington be definlated using this manual. AII critical areas wittrinthe City of Port Townsend areiegulated according to the Port Townsend Municipal Code Critical Codes Ordinance 6NO. Z*ll, Lrty 2005 PTMC). The methodology outlined inthe 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 ajurisdictional wetland it must have a positive indicator from all three parameters. All wetlands identified using this methodology may be federally regulatd regardless of size. Soils A hydric soil is a soil that forrns under conditions of saturation, flooding, or ponding lasting long enough during the growing season to result in an anaerobic upper layer. Hydric soils favor the growth and regerreration of hydrophytic vegetation. The indicators for this type of soil include low chrom4 mottles, gleying, and high organic content within the upper 32 inches of the soil profile. Holes were dug on the site and soil colors (including value and chroma) were recorded in the top 16 inches. Soil colors were analyzed'using GMunsell Color Charts (1992). Vegetation Wetland plant species must constihrte greater thanSlo/oof the total vegetation present to meet the qualification as a site dominated by hydrophytic vegetation. Dominance of plant species is determined by calculating actual aerial cover within a 3O-foot radius for hees, a 1O-foot radius for shrubs, and a 6-foot radius for the herbaceous layer at each data point. Commonly occurring plant species have been rated by the United States Fish and Mldlife Service (USFVD National List of Plant Species That Occur in Wetlands: Northwest (Regron 9) as to their frequency of occurrence in wetlands and non-wetlands. During thefieldworh each species was recorded and given a rating based on indicator stafus and percent cover. Hydrologt Wetland hydrology is defined in the Washington State Wetland Identification and Delineation Manual as "areas that are periodically inundated or have soils sahrated to the surface at some time during the growing season."

The growing season can also be defined by soil temperature at19.7 inches below the soil surface being higher than biological 0 (5"C or 40"F). lndicators of hydrology include visual observation of inundation or soil saftration, water- stained leaves, cracking of the soil surface, and/or sediment deposits. Positive signs of hydmlogy are often absent during the summer and fall months but can be infened if there are positive indicators of hydric soil and hydrophytic vegetation. Classification Wetland categorization was determined using the Washington State Department of Ecolory @OE) Wetland Rating System Revised (Ecology Publication #04-06-025, eugusiZOO4), according to type and class ofwetland. The wetland is assigned a numerical value for water quality function, hydrologic function, and habitat frrnction. The total score determines the category of wetland Wetlands are rated as entire systems and quite often exceed project boundaries. Ratings ftmge from Category I to Category [V; Category I is the highest qualrty wetland. Buffers are assigned according to land use and numeric scores. Category I wetlands are not replaceable and therefore receives the largest buffers and highest protection. I)etermining 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 or all of the requirements were not present. The wetland edge is flagged between the pairs of points at intervals of 20 to 40 feet.

[mailto : rmra46 1 @ ECY.WA.GOV] Senk Wednesday, September 13, 2006 4:08 PM To: Judy Surber Cc: Suzanne Wassmer; Lund, Perry Subject: Third party wetland delineation review Hello Judy: Thanks for the opportunity to provide assistance regarding the delineation for the wetland just north of Hastings Avenue in Port Townsend. Based upon the site visit, Ecology staff determined that certain Hydrologic Functions of the wetland were not present, thereby yielding a score that resulted in a Category lll ranking. Specifically, the wetland is topographically isolated from other down gradient systems and does not have the opportunity to reduce flooding and erosion. This aspect eliminates the use of a multiplier in the ratings system that would have resulted in a Category ll ranking. Thus, in conclusion, the system is accurately rated a Category lll. lf you have questions or require clarification of this determination, please contact me.
