Schmitt, Biologist 809 37th Street Anacortes, Washington 98221 360-293-8599 fR E(t~]B:1r\\ITF;)f')) Field Visits: 8-24-25-2000 f .~1 ~ . f" r'o;"'I"';-~ \,., ~...l ~- L,,-i.~_;- (1) Site Plan: si te Plan will be submitted by the property owner IHH~\:!'ulI~P W' ,(2) Project Narrative: lv1': Nannery plans to construct an effluent line which will run along the driveway, maintain a 50 foot distance from the ground well, pass through the meadow and go to the septic tank. In the future he would like to construct a residence em the property. This property is within 200 feet of a possible wetland and therefore requires a Critical Areas Assessment for future building permits. The property extends from the top of a bluff overlookingTarboo Bay. A small temporary structure, a well, a septic drain field (inspected 11-15-94), and a mobile trailer are on the lot above the bluff. Grass covers ~r4"; ~ s 4. f'C-'7; much of the property except for the low bluff area which has trees and shrubs. The lot contains" acres, with shoreland excluded, and over 1 acre with tidelands included. Some of the land in this area appears to be transitioIDng from hydric to non hydric. Most of the plant cover is non hydric other than a patch of roses and a small area of sedges. (3) Adjacent Land Uses Tarboo Bay is to the East A commercial venture is to the North. Undeveloped land is to the South. A cabin is across Carl Johnson Road to the West. METHODOLOGY Rupert Schmitt conducted an on-site investigation during August 2000. Rupert is a professional biologist who has taken the Wetlands Plant Identification Course offered by the US Fish and Wildlife Service and the Wetland Delineation Course offered by the US Army Corps of Engineers. He has had additional wetlands training also, and is a member of the Society of Wetland Scientists. He has done botanical, vertebrate and invertebrate research and has worked for Federal and local units of government and the private sector as a general contractor in landscaping. This site investigation includes: (1) an investigation of published information to acquire knowledge of site conditions, and (2) an on-site investigation of the existing property to assess the impacts of the proposed development. The onsite methodology includes documenting existing conditions on site and on adjacent property within 200 feet from site of proposed developmental activities. Fieldwork included observations of drainage patterns on site and within the general vicinity, inventorying plant communities, and estimating the location of the proposed development. Plant identifications were made with the aid of Plants of the Pacific Northwest Coast (Pojar and MacKinnon, 1994; a Field Guide to the Common Wetland Plants of Western Washington and Northwestern Oregon (Sarah Spear Cooke, Editor), 1997; and Vascular Plants of the Pacific Northwest, 5 volumes, 1969 (Hitchcock, Cronquist, Ownbey and Thompson). Soil identifications were made with the aid of Soil Survey of Jefferson County Area, Washington, by Fred R. McCreary, USDA, Soil Conservation Service, 1975, Sheet 57; and Munsell Soil Color Chart (Macbeth Division of Kollmorgen Instruments Corp. 1992. RESUL TS OF LITERATURE REVIEW The ESRI Arc Explorer map indicated that a wetland was located on the northern 50 feet of the Nannery property and approximately 200 feet east of Carl Johnson Road. This wetland was shown to continue north for approximately 180 feet north on the adjacent property. No wetlands were shown for the property south of the Nannery property. Tarboo Bay was also indicated as being a wetland. Alderwood Gravelly Loam 0 to 15 percent slopes was shown as the expected site soil. It is listed as a non-hydric soil. It also has a perched water table above the cemented layer during the winter months. The cemented layer's depth ranges between 20 to 40 inches. Alderwood soils are moderately well drained. Typical soil profiles are 1-6 inches lOYR 4/4; 6-12 inches lOYR 4/4; 12-21 inches lOYR 4/3. I~jt~)t 'iiB;}(\V IE 11 Ii ~ \ t '~,.. j ..,0_. \,{ 1"1"":"" ,"", \ , t..

It is 100- feet wide and 470.95 feet on the north property line to the top of the bluff and 462.55 feet on the south property line to the top of the bluff. The Ordinary High Water Mark (OHWM) is close to the base of the 12 foot bank. A rocky pebble beach with much clay under pebbles. Silt, sand and mud are on on the tide flat. Clams and a few oysters live in the mud flat. Distichlis spicata grows on the upper beach. Some drift wood is on the higher part of the beach. On Site: Slope is 8 to 15 Percent. Lot goes to saltwater tideflats. With tideland property included, lot is over 55, 000 square feet. Bluff has some Douglas -firs about 15 years old, and a few grand firs. The lot has a variety of horticultural varieties of trees including austrian black pine, 2 monkey puzzle, 3 Port Orford cedars, walnut, ornamental cherries, 1 . peach, 1 plum, 2 pears, 2 apples, ornamental cherries, 3 silver birches, ornamental maples, 10 clumps of bamboo and red cedar, 1 service beny. The dominant grass of the property is tall fescue, Festuca arundinaceae, FAC-. The dominating presence of this grass excludes most of this property from further investigation as wetland. Other herbs include iris (plantedd by Mr. Nannery) and ornamental grasses and Pampas grass. The South edge of the lot above the bluff is bordered by a curtain drain which ends 108 feet short of the top of the bluff and comer stake near the top of the bluff. This curtain drain has no outlet and appears to have its water absorbed into the soil. It is still functioning. The curtain drain was installed by the developer. The salesman of the property, Jim Olson, has retired. An old partly collapsed drainage ditch borders part of the north. A small shallow ditch crosses the lot about 120 feet west of the top of the bluff. It shows no evidence of wetland plants and has minimal effect on drainage. A ditch is alongside Carl Johnson Road. The water flows from North to South. A small wetland on the Nannery property, of 1400 square feet is way below 10,000 square feet and was therefore not delineated. Class III and IV wetlands 10,000 square feet or larger in size are covered by the Jefferson County CAO (6.302). The small exempt wetland is marked with white flags along its perimeter. Another wetland area of 625 square feet is east of this patch. The dominant vegetation covering most of the Nannery lot is Tall fescue, Festuca arundinaceae, FAC-. This is a non wetland grass. A little east of the parking area there is a patch of giant horsetails, FACW, canada thistle, rubus laciniatus, (evergreen cutleaf blackberry), Rubus ursinus (trailing blackbeny), and Douglas Fir, 10X15 feet in size (approximately 150 square feet). A Nootka rose patch is east of this area. Soil in this area is SYR 2.5/2 with mottles. The soil is hydric. The rose patch on the Nannery property runs 26 feet along the fence with a width ranging from 15 to 17 feet. A soil pit within the rose patch read 7.SYR 3/2 with faint mottles. 13.6 feet south a pit showed 7.SYR 3/2 with a few mottles. An isolated patch of Carex obnupta 30% and 10% Festuca arundinacea is marked with a wooden stake. Nannery Wetland Site Assessment 1035 Carl Johnson Road, Qui1cene, W A 98376 Oct. 2,00 Rupert Schmitt, Wetlands Consultant, 809 3~ Street, Anacortes, WA 98221 360-293-8599 page3 . 29 feet south of the rose patch a pit read 7.5 YR 3/1 with infrequent mottles 8" down. Festuca arundinaacea which is FAC-had 95% coverage. This pit was non wetland based upon vegetation. This location is 25 feet north of the edge of the septic tank. And 29 feet south of the edge of the rose patch. The soil is this area appears to be transitioning from hydric to non hydric. Plant cover is non hydric other then the patch of Rosa and a small area of Carex. A ditch runs along the western edge of the property. Giant horsetail and one birch are on the slopes of the ditch. American speedwell, Veronica, is in the deep ditch running on the south part of this ditch. The adjacent lot to the North, in the area indicated as wetland on the ESRI Arc Explorer map, was investigated. A soil pit indicated hydric soil, 7.5 YR 3/2 with mottling. No water or saturated soil was in the pit. Grasses (vegetation) were non hydric and included sweet vernal 'grass, Anthoxanthum, FACU, and tall fescue, Festuca arundinaceae, FAC-. Approximately 200 feet north of the Nannery north property line there are two shallow west to east drainage ditches on swales which would slightly affect the drainage. No attempt was made to measure the hydric soils on the property north of the Nannery property because the vegetation was non hydric. The data from the ARC Explorer printout appears to be no longer valid regarding this northern ''wetland''. The upper slope of this lot has Douglas-fir, Oceanspray, a few salmonberries, and lower down on the slope thistles, trailing blackberry, sword fern, a few Rosa, one hawthorne, and a few clumps of Juncus, and orchard grass reaching to a point level with Mr. Nannerie's pumphouse. Further east were found scotchbroom, and Douglas- fir. Further east were orchard grass, Sweet vernal grass, narrow leaved plantain, red fescue, bracken fern, a few clumps of Juncus, a few equestetum, common velvetgrass, and a patch of Rosa adjacent to Mr. Nannerie's pumphouse. The patch of Rosa Nutkana measures 26 by an average of 16 feet. No Carex were in this area The Neighboring lot to the South has a possible exempt wetland in a triangular shape with the tip of the triangle pointed towards the Nannery property at a point approximately 108 feet west of the top of the bluff. This area has a base measuring 50 feet and two sides measuring 67 feet with an area of 1800 square feet. It is bordered by Douglas fir on two sides and upland grasses on the upslope side. Wetland plants of this wetland included manna grass, Glkycera, and Festuca Arundinaceae in addition to evergreen trailing blackberry. Adjacent to the road, this lot has a slope with a patch of giant horsetail and trailing blackberry, 4OX35 feet, with two climps of Juncus, some Holcus lanatus, Festuca sp. And Agrostis sp. And a few Ranunculus. Southeast of the property, over 100 feet from the Nannery property line there are small wetland areas with a variety of Carex sp. The curtain drain along the northern edge of this neighboring lot has many alder saplings growing in the ditch. Streams flowing down the slope to the northwest and southwest of this lot are narrow with no wetland borders. A stream passes beneath Carl Johnson Road through a culvert over two hundred yards north ~f the ~ropertr A"" ~. spring feeds another stream approximately 150 yards south of the property line. \R iEA E\\~) IF)' \1 , : ~ V ,)..

(6) Regulatory Analysis Jefferson County Interim Critical Areas Ordinance (Jefferson County, May 91994: Amended June 26, 1995 covers wetland regulations. This exempt wetland was rated using the Washington State Department of Ecology's (WDOE) Washington State Wetlands Rating System (WDOE 1993) to determine the category of the wetland as required in Section 6.301 classification, of the Jefferson County Interim Critical Areas Ordinance. The wetlands ar~ted as Category III wetlands. Category III wetlands have a habitat score for significant habitat value of less than or equal to 21 points. Generally these wetlands are smaller, less diverse, and/or more isolated in the landscape than Category II wetlands.

Street, Anacortes, WA 98221 360-293-8599 page5 The Nannery freshwater wetlands and the wetlands of adjacent properties are under the dimensional threshold. There will be no Critical Area Ordinance regulatory impact from freshwater wetlands on the proposed construction of a future residence and associated structures. SETBACKS Fifty foot setback for the wastewater transport line from the well. The tight line from the drain field must be at least 10 feet from surface water. No surface water was observed during this study. However it would be prudent to keep the tight line over 10 feet from the area marked in the field as exempt wetland. Thirty foot setback from the top of the bluff (above the Ordinary High Water Mark (OHWM) of Tarboo Bay). The OHWM is east of the foot of the bluff. Mr. Nannery has no plans for doing any construction activities within 30 feet of the top of the bluff. No streams cross the property (Stream setbacks for Jefferson County for type 4 streams are 25 feet from the OHWM for high intensity areas of more than one dwelling per acre and 15 feet from low intensity areas of less than one dwelling per acre). Boundaries determined by other qualified delineators at different times of the year may not coincide exactly with this assessment because of differing hydrological conditions.
