INTRODUCTION Wetland delineation and analysis was requested by Daniel and Kathryn Molotsky for their property on Thomas Street in Port Townsend, Washington. The Molotslcys plan to build a 352 square-foot addition on their house, replace a concrete patio and disconnect a septic system and connect to city sewer on 25th Street. Previous wetland study on the property includes a level 1 review in June 1998 by Dixie Llewellin, of Olympic Wetland Resources and a delineation in November 1998 by Matt Bennett, of the Coot Company. The 1998 delineation was surveyed by Polaris, Inc. for the City of Port Townsend. parcel acres owner address S/T/R land use 001-033-003 8.32 Daniel & Kathryn Molotsky 2710 Thomas Street 3/30N/1W residential <1 d.u/acre At apre-application meeting on April 29, 2009, Port Townsend Planner Judy Surber indicated that the wetland delineation should be reviewed, a current wetland rating be performed and that any impacts to critical areas or buffers be addressed by an appropriate buffer-averaging, enhancement or mitigation plan in accordance with the Critical Areas Ordinance (CAO), Chapter 19.05 of the Port Townsend Municipal Code (PTMC 2009). She also indicated that the delineation could be limited to the portion of the wetland that was near the project area. The goal of this report is to evaluate current wetland conditions on the site and provide a buffer enhancement plan for anticipated impacts to wetland buffers. The first section of the report will present the results of the delineation and rating and the second will address impacts to wetland buffers. This report was initially submitted June 26, 2009 and an Addendum was prepared July 22. Revisions requested by Ms. Surber August 20 and 21 have been incorporated into this revised report along with the previous addendum. Therefore this document contains the entire project information. 2. WETLAND DELINEATION REPORT 2.1. Methods Wetland delineation was conducted under the guidelines of the Washington State Wetland Delineation Manual (Ecology 1997) as defined in 19.05.020 of the CAO. Background data was collected on the subject site before fieldwork was conducted. Data gathered included aerial imagery, topographical maps, soil surveys, national and local critical areas inventories and previous reports. The subject site was walked on foot and observations of vegetation, soils and surface hydrology were made. Data points were established near the project area and observations of wetland indicators were made. Data sheets are included in Appendix A. At each data point vegetation was observed in 30-foot radii (for trees and shrubs) and a 10-foot radius for herbs. Percent cover was visually estimated. Dominant species in each layer (trees, shrubs and herbs) was identified and listed with wetland indicator status from the United States Department of Agriculture PLANTS database (USDA 2008). Soils were observed by digging a test pit to a depth of 16 inches. Layers were identified, measured and recorded according to changes in texture and/or color. Hydric indicators such as organic content, sulfide odor, and moisture regime were recorded. Each layer was analyzed for chroma and hue with a Munsell soil color chart. Mineral soils with a chroma of 1 or gley, or matrix chroma 2 or less and distinct mottles (at least 2 degrees of hue more colorful) are considered hydric (Ecology 1997). Soil characteristics were compared to those of the mapped soil type in the Natural Resources Conservation Service soil survey (NRCS 2009). MichaelB.DawsonC~gmail.com • 1361 51St Street • Port Townsend • WA 98368 • 360-385-1773 Molotsky Wetland Delineation, Revised 2009-08-26 p. 2 of 35 Depth to water in the test pit, or of surface water within 30 feet, was measured. Other primary indicators of wetland hydrology such as high water marks, drift lines, sediment and/or algae deposits and drainage patterns were recorded. One primary indicator of hydrology during 12.5 percent of the growing season (or 5 percent with stronger than facultative vegetation - as little as 9 days in the Puget Sound region) is considered to be wetland hydrology (Ecology 1997). Two secondary indicators of hydrology (oxidized root channels, water-stained leaves, confirmed mapped hydric soils, strongly hydrophytic vegetation) are also considered to be wetland hydrology. The portion of the wetland boundary near the project area was marked in the field with pink flagging printed "WETLAND DELINEATION" and labeled with a sequential flag number (1, 2, 3...) placed every 20 to 30 feet. Soils were occasionally probed as the boundary was walked to confirm the similarity to previously observed soils and subsurface hydrology as needed. Location of wetland flags was recorded with gps and mapped in ArcView 9.3 to layers provided by Tyler Johnson of the City of Port Townsend. Wetlands were rated according to the Washington Department of Ecology Revised Wetland Rating System foY Western Washington (Ecology 2004). The October 2008 revised rating form was used (Appendix B). The updated list of natural heritage wetlands from the Washington Natural Heritage Program was consulted (NHP 2008). Buffers were determined according to PTMC 19.05.110 E Buffers and Setbacks and flagged in the field measuring perpendicularly from the delineated edge with a measuring tape. 3. BACKGROUND 3.1. Topography The United States Geological Survey (USGS) topographical map, Port Townsend South quadrangle, shows the Molotsky parcel to be nearly level (Figure 1) with slopes less than 15 percent grade. A small plateau at the crest of Hastings Avenue contains a number of poorly drained areas. Drainage ditches, circa 1970s or earlier have been constructed to help drain this area to the southeast, northeast and west. Fill from past road construction may have also impounded waters in some areas, such as upslope of Hastings Avenue. The Molotsky property is 226 to 242 feet above sea level and is located approximately eight-tenths of a mile northwest of Kah Tai Lagoon. 3.2. Site History Pre-settlement vegetation type for this area was likely coniferous forest. Clearing by settlers began in the late 1800s with conversion to agriculture. The site was in operation as a dairy farm previous to ownership by the Molotskys in the 1980s. 3.3. Soils The Natural Resources Conservation Service (NRCS 2009) Web Soil Survey map indicates the entire site is TuC-Tukey gravelly loam, 0 to 15 percent slopes (Figure 2). TuC-Tukey is an upland soil (NRCS 2009) although it does have a dense layer that can lead to a perched water table in wet seasons. CmCClallam gravelly sandy loam, 0 to 15 percent slopes, lies just to the southwest of the property. 3.4. National Wetland Inventory The United States Fish and Wildlife Service (USFWS 2009) National Wetland Inventory NWI) map shows two freshwater wetlands within one-half mile north of the site, but none on the subject property (Figure 3). To the southeast of the Molotsky property a 1.15-acre PSSC MichaelB.DawsonC~gmail.com • 1361 51St Street • Port Townsend • WA 98368 • 360-385-1773 Molotsky Wetland Delineation, Revised 2009-08-26 p. 3 of 35 Palustrine, Scrub-shrub, Seasonally-flooded) wetland is inventoried. To the northeast, a 0.6- acre PEMC (Palustrine, Emergent, Seasonally-flooded) wetland is mapped. 3.5. Environmentally Sensitive Areas Map The Port Townsend Environmentally Sensitive Areas (ESA) map shows four wetlands on the subject property (Figure 4) and several additional wetlands within one-half mile that are not inventoried on the NWI map. A critical drainage corridor is also mapped running from the northwest property corner at Hastings Avenue to the southeast property corner and offsite to the 1.15-acre PSSC wetland. The onsite wetland polygons on the ESA map were from the 1998 Coot Company delineation and Polaris survey. The Deering wetland is inventoried directly to the north of Hastings Avenue. 3.6. Previous Reports The Level 1 Wetland Review by Olympic Wetland Resources (Llewellin 1998) includes a wetland rating done under the old (pre-2004) rating system. The onsite wetlands were rated as Category III under this system. The delineation by the Coot Company (Bennett 1998) found four onsite wetlands labeled A, B, C and D, the three westernmost of which (A through C) were determined to be a mosaic due to their proximity to each other. These were rated by Bennett as Category III wetlands and the fourth (Wetland D) as a Category IV wetland under the old system. Under 1998 regulations, a 50-foot buffer was applied to the Category III wetlands and a 25-foot buffer was applied to the drainage corridor. The Bennett report also presents data from the City of Port Townsend Stormwater Flooding Maps of 1996 and 1997. 1998 Coot Co. name acreage 1998 category Wetland A 0.20 III Wetland B 0.15 III Wetland C 0.13 III mosaic total 0.48 Wetland D 0.15 IV 4. FINDINGS Fieldwork was conducted on May 5, 2009, under partly sunny skies with an ambient air temperature of 52 degrees Fahrenheit. The parcel was walked on foot and observations of vegetation, soils and hydrology were made. The property is accessed via Thomas Street. The Molotsky residence is located at the western property boundary. A barn is located to the south. Higher ground to the east and southwest slopes gradually to the center of the property and to the southeast. The parcel is pasture with shrubs colonizing the fencelines at the property margins. Three data points (DP) were established at representative upland and wetland locations (Figure 5 and Appendix A). A freshwater depressional wetland was found onsite that corresponds to the mosaic of Category III wetlands found in the Coot Company report. This area will be referred to in this report as Wetland A. See Figure 5 for a map of wetland boundaries. A ditch with seasonal stream flow was also found in the inventoried drainage corridor and will be referred to as Ditch A. MichaelB.DawsonCc~gmail.com • 1361 51St Street • Port Townsend • WA 98368 • 360-385-1773 Molotsky Wetland Delineation, Revised 2009-08-26 p. 4 of 35 4.1. Wetland A Wetland A is a depressional wetland located in the northwestern corner of the subject parcel and extending a short distance north onto the Hastings right-of--way. It is approximately 0.87 acres in size based on a partial delineation, gps measurements and estimation of the remaining wetland boundary. The majority of the wetland is dominated by emergent vegetation with a smaller area of shrubs at the northwestern margins along Thomas Street and Hastings Avenue. Small areas of open water were present in Ditch A. Data points were placed near the project area and not near the center of the wetland where stronger wetland vegetation was located. DP-1 was established near the southwestern edge of Wetland A towards the project site. DP-2 was located between DP-1 and the house. DP-3 was located to the southeast of the house. See Appendix A for data sheets. The Molotsky property is occasionally mowed for hay. The disturbance of mowing makes identification of plant species difficult, may reduce the diversity of species and introduce invasive species that are not good indicators. For the purposes of this delineation, the site was treated as a disturbed area (Atypical Situation), although the frequency of mowing is not high and five to seven plant species were identified at each DP. Additional discussion of the plant community will be presented below The site is also a seasonal wetland, and as such is considered a Problem Area, however the site was visited in spring when hydrological indicators were more likely to be present and previous data for the onsite wetlands is available making additional data collection unnecessary. 4.2. Soils Soils at DP-1 were silt loam to gravelly silt loam with lower layers showing low matrix chroma and prominent mottles, indicating seasonally hydric conditions. Munsell readings in the layer 9 to 16 inches below surface were lOYR 3/2 with few, medium-size, prominent mottles of 7.SYR 4/6. The observations did not confirm the mapped Tukey soil type, however the gravelly parent material was evident. Soils at DP-2 were similar to those at DP-1 except that the mottled soil layer was slightly deeper 10 inches below surface) and soil texture was less gravelly. Soils at DP-3 were significantly different with only faint mottling (lOYR 3/2 matrix with lOYR 3/4 mottles) that did not look redoximorphic. Soils at DP-3 were clearly upland. 4.2.1. Hydrology Surface water was present in Ditch A to a depth of about 16 inches. At DP-1 the upper four inches of soil was saturated and filled the test pit to 13 inches below surface, although this water seemed to be coming from upper layers. Algal mats from higher water levels earlier in the year had been deposited on grass in DP-1. Wetland drainage patterns are evident from the shallow topographic basin and slow permeability of the soil. DP-1 was located in an area that has been mapped by the City of Port Townsend as occasionally flooding (Bennett 1998). DP-2 had slight moisture, but no soil saturation or ground water within 16 inches of the surface. No algal deposits were present. DP-2 was slightly higher in elevation than DP-1 and so drainage patterns were less characteristic of wetland conditions. It is believed that DP-2 would have seasonal saturation in the wettest times of year, much of which probably occurs outside of the growing season. However DP-2 may be inundated in the wettest years, of which 1997 was the most recent example. From observations of this and other nearby wetlands over the past five years and from previous reports, this type of flooding appears to occur less than 5 out of 10 years on average. MichaelB.DawsonC~gmail.com • 1361 51St Street • Port Townsend • WA 98368 • 360-385-1773 Molotsky Wetland Delineation, Revised 2009-08-26 p. 5 of 35 DP-3 had no signs of hydrology and exhibited upland characteristics. A failed septic system leaks from the northeast corner of the house into Wetland A (Figure 5). It is hard to separate the effect of this input of water from the natural wetland hydrology, however there is a slight slope with a difference of elevation of about 3 feet between the drain field and the flatter portions of Wetland A. Water from the drain field can be seen spreading downslope in a northeasterly direction and appears to be the only source of water in this slope. At the base of the slope it meets a high water table from Wetland A. Ditch A was constructed in the 1960s or earlier to drain the field for cow pasture. A culvert from the Deering wetland under Hastings Avenue is the inlet for Wetland A. Water flow is constricted in the center of the property by an undersized or clogged culvert. A secondary constriction due to bank erosion is present at a bend in the ditch downstream of the culvert. From there Ditch A flows southeast into an offsite wetland and terminates. There is no surface connection with Kah Tai lagoon or other body of water. Ditch A is a Type Ns non-fish-bearing seasonal stream. 4.2.2. Vegetation Wetland A is dominated by emergent plants, mainly grasses, with a margin of shrubs to the north and west. Some of the shrub-dominated fencelines are outside of the wetland boundaries. The center of Wetland A was not sampled, but wetland plants Juncus effusus (soft rush, FACW) and AlopecuYUS sp. (likely water foxtail, OBL) were observed there. Less than 50 percent of dominant plant species at each data point were hydrophytic, however slight differences were seen in relative abundance of some species. Tall buttercup (Ranunculus acYis, FACW-) was only present at DP-1 while dandelion (TaYaxacum officinale, FACU) and Canada thistle (Cirsiurn arvense, FACU+) were more prevalent in the upland locations. Seasonal wetlands in old pasture in the Port Townsend area sometimes have weak indicators of wetland vegetation and more weight was placed on soils and hydrology in this delineation based on professional judgement. 4.2.3. Classification Wetland A was rated as a depressional wetland based on the functions it provides for water quality, hydrologic functions and habitat value (Appendix B). With a total score of 40, Wetland A is a Category III wetland. Since mowing doesn't typically take place during the wet season and vegetation is likely greater than six inches in height during the time surface waters might transport sediments and pollution, Wetland A was given S points for question D 1.3 CharacteYistics of peYSistent vegetation. Seasonal ponding is typically less than 1/4 of the total wetland area, although larger flood events have occurred less than 5 out of 10 years on average. See Figure 6 for Cowardin classes and hydroperiods. The habitat score was low at 10 points due to limited vegetation structure, diversity and interspersion of habitats and the degraded buffers and connections with other wildlife areas. 5. DISCUSSION The southwestern boundary of Wetland A was flagged in the field from the edge of shrubs north of the house to the culvert in Ditch A southwest of the house. This southwestern edge of the wetland is the only part near the anticipated project impacts of building the addition to the residence and ditching for installing the sewer line. The remaining wetland boundary shown in Figure 5 was estimated from observations made in the field and from interpretation of the aerial photo. The estimated area of the wetland (0.95-acres, from ArcView polygon) is larger than the 0.48-acre area surveyed in 1998. Part of this is due to the inclusion of the area of Ditch A that MichaelB.DawsonC~gmail.com • 1361 51St Street • Port Townsend • WA 98368 • 360-385-1773 Molotsky Wetland Delineation, Revised 2009-08-26 p. 6 of 35 provides a hydrological connection between the three depressions referred to as A, B and C in the Coot Company report. The section of Ditch A within the wetland boundary functions most like a depression with no perceptible flow in the ponded water. Part of the increase in wetland size may also be due to reduced capacity of Ditch A to drain the area. In general, though, Wetland A is similar in shape to the mosaic of wetlands previously delineated. 5.1. Buffers Category III wetlands larger than 1,000 square-feet in size are regulated in Port Townsend by the CAO. According to the buffer width table (CAO 19.05.110 E3) Category III wetlands with habitat scores below 20 points receive 60-foot buffers for moderate-impact land use at less than one dwelling unit per acre. A 25-foot buffer is indicated for Ditch A downstream of the culvert for protection as a critical drainage corridor. Upstream of the culvert, Ditch A is part of Wetland A, which has a larger buffer. In addition, a 15-foot setback from the buffer edge is required for placement of permanent structures. 6. ENHANCEMENT PLAN 6.1.Introduction Construction plans involve anticipated impacts to the buffer of Wetland A. The 60-foot buffer currently extends to the middle of the existing residence and continues southeast through yard and pasture (Figure 5). Construction plans involve adding a 16 by 22 foot addition to the house, removing an existing 9 by 24 foot concrete patio and replacing it with a 15 by 16 foot one, and disconnecting a septic system and installing a sewer line to connect with city sewer in 25th Street to the south of the property. The addition has been designed by architect Andy Reece and the sewer plan was designed by Bernt Ericsen Excavating, Inc. 6.2. Baseline See 4.2.3 Classification discussion above and Rating Form (Appendix B) for baseline data on functions Wetland A provides. 7. IMPACTS TO CRITICAL AREAS Impacts to the buffer of Wetland A will be from the 352 square-foot addition and it's associated 15-foot setback. The trench for the sewer line will be routed to exit the south side of the addition and avoid the buffer throughout it's route south to 25th Street. The proposed patio replacement will be on the south side of the house and outside of the 60-foot buffer. A proposed dispersion trench will be located in the setback adjacent to the reduced buffer and is discussed below (see 7.3 Drainage Plan). The total area of impact from the addition plus setback will be 1,372 square feet (352 addition + 1020 setback). 7.1. Wetland Functions 7.1.1. Water Quality Wetland A currently filters pollution from roadside ditches, residences and a failed septic system through an occasionally-ponded depression vegetated with shrubs and pasture grasses. The project will disconnect the septic system that is a source of water pollution in Wetland A. This will be a primary reduction in impact to Wetland A. 7.1.2. Hydrologic Functions Wetland A currently helps to regulate storm flow through Ditch A that may impact residences located downstream during major storm events. Flow is somewhat slowed and regulated by the gentle topography and vegetation. The project will add 352 square feet of impervious surface to the property and a drainage plan is detailed below to address additional roof runoff. The 8-acre MichaelB.DawsonC~gmail.com • 1361 51St Street • Port Townsend • WA 98368 • 360-385-1773 Molotsky Wetland Delineation, Revised 2009-08-26 p. 7 of 35 parcel currently has a low impervious surface coverage of less than 10 percent. The addition will not add a large amount of surface but the addition will be within the buffer of Wetland A. 7.1.3. Habitat Wetland A has low habitat value based on the low species diversity, degraded buffers and disrupted corridors. Steps to maintain or improve habitat functions will be detailed below in the enhancement plan. 7.2. Impact Avoidance and Reduction Construction alternatives have been considered for project, including the building of a second residence on the property instead of adding an addition; adding a larger addition; adding an addition onto another part of the house; not taking any action. The desired alternative -adding a 352 square-foot addition to the east end of the house - combines a modest-sized addition with the most practical part of the existing structure to modify due to roof lines, interior structure and proximity of the house to Thomas Street. In addition, the disconnecting of the failed septic system will be a large improvement in water quality and a reduction in impact to Wetland A. 7.3. Drainage Plan The Molotsky property consists of a 8.32-acre (362,371 square-foot) parcel with an existing single-family residence 33 by 43 feet in area and a barn 47 by 53 feet in area (measuring rooflines). In addition there is a gravel drive 20 by 30 feet in size and two concrete patios (9 by 24 and 17 by 22 feet in size). The total existing impervious surface is 5,100 square feet, or 1.41% of the total property area. Area Impervious surface (s.f.) of total surface House 1,419 Barn 2,491 Drive 600 Patios 590 Total existing 5,100 1.41 Proposed addition 352 Remove old patio 216 New patio 240 New total 5,476 1.51 The proposed addition adds 352 square feet, plus 24 square feet increase in patio space, brings the total impervious surface to 5,476 square feet or 1.51% of the total property area. The Department of Ecology Stormwater Management Manual for Western Washington Ecology 2005) was used as guidance in developing the drainage plan. Section 3.1 of Volume III discusses roof downspout controls. Since a seasonally high water table exists onsite that may reach within three feet of the finished grade, a dispersion trench system is proposed for MichaelB.DawsonC~gmail.com • 1361 51St Street • Port Townsend • WA 98368 • 360-385-1773 Molotsky Wetland Delineation, Revised 2009-08-26 p. 8 of 35 handling roof runoff. For single-family lots greater than 22,000 square feet and for downspouts draining less than 700 square feet, one 2-foot by 10-foot dispersion trench is indicated. One condition for using dispersion trenches is that greater than 25 feet of vegetated flowpath must be present between the trench outlet and any wetland. The proposed location for the trench is to the east of the addition in the setback adjacent to the reduced buffer. Wetland A lies 30 to 60 feet downslope of the proposed trench outlet on a gradual slope. This should provide more than adequate vegetated flowpath for dispersal of the anticipated runoff. Vegetation in the flowpath should remain unmowed, except for occaisional control of invasive species (see 8.8 Maintenance and Contingency Plans). The addition roof will be a simple gable with a ridge running east-west. Gutters along the north and south rooflines will each drain to a downspout at the eastern corners. Downspouts will be connected directly to 4-inch corrugated solid pipe buried in a shallow trench in the setback to the east of the addition. The two pipes will converge in a wye to a 6-inch catch basin and then drain to 4-inch perforated pipe in the dispersion trench. The trench will be constructed by Bernt Ericsen Excavating to the details specified in the plan and section drawings (Figure 8). The dispersion trench will drain east towards the wetland buffer. No other impervious surfaces, structures, roads or steep slopes exist onsite downslope of the dispersion area. 8. ENHANCEMENT 8.1. Goals and Objectives In addition to improving water quality through removal of the septic system, reduction of impacts to habitat and hydrological functions are proposed. Two options for addressing the project impacts are buffer averaging (expanding the buffers in one area to compensate for reducing them at the project site) and enhancement (increasing the function of degraded wetlands and buffers through planting while allowing a reduced width at the project area). The landowner's preferred option is an enhancement plan to reduce impacts to critical areas from the proposed project. The goal of the enhancement plan is to establish conditions that will allow a native plant community of shrubs and trees to dominate the enhancement area. The long term goal is to ensure no net loss of wetland functions onsite. Objectives of this plan are to: Define a reduced buffer that allows for the addition and a reduced setback while giving adequate protection to Wetland A. Mark the buffer edge onsite to prevent encroachment during construction. Install silt fencing along the buffer edge. Plan for the reestablishment of native forest and shrub cover within a 1,400 square-foot enhancement area north of the house. Restrict mowing within the reduced buffer area to hand trimming done for invasive species control and enhancement area maintenance. Control invasive species in and around the restoration area. Allow for maintenance of the existing culvert in Ditch A. 8.2. Buffer Reduction The 60-foot buffer will be reduced only in the area needed for the addition and a reduced setback around the addition sufficient for maintenance and access. The northeast corner of the addition will protrude farthest into the wetland buffer, reducing the buffer in this location to a MichaelB.DawsonC~gmail.com • 1361 51St Street • Port Townsend • WA 98368 • 360-385-1773 Molotsky Wetland Delineation, Revised 2009-08-26 p. 9 of 35 minimum of 25 feet at one point near wetland flag 3 and increasing to 60 feet to the north and southeast of the existing house. The setback at the northeast corner will be reduced to a minimum of 5 feet pending approval by the City Planning Director. As a concession for this reduced setback, the owner shall build no doors or exits (except required emergency window exits) on the north or east sides of the addition. 15-foot setbacks will be maintained at the west and south sides of the addition. It is proposed that the final buffer edge be marked onsite to clearly define the zone where clearing of native vegetation is prohibited. Buffer signs maybe obtained from the City of Port Townsend Public Worl~s Department. Silt fencing should be installed along the buffer edge prior to construction to reduce sediment transfer into the wetland. An existing wooden fence along the northeast side of the house should remain to provide separation of lawn and buffer. 8.3. Drainage Corridor Maintenance of the existing culvert in Ditch A will be allowed including periodic cleaning using hand tools and the clearing of vegetation around the intake and outlet to prevent clogging. 8.4. Enhancement Design Fa;~ ,~a= y :,~., ~~ ~ to lP~, ~ i rf ~^~ ~ Y~ `.:s~~`~ ~ A 1,400 square foot area of degraded wetland has been designated to the north of the project area between the project site and the center of Wetland A (Figure 7). The area is approximately 70 feet by 35 feet and triangular in shape. The plantings will extend from an existing hedge at the west property boundary to Ditch A. This band would provide a screen between the house and the area of seasonal ponding that attracts wildlife in the northern part of Wetland A. MichaelB.DawsonC~gmail.com • 1361 51St Street • Port Townsend • WA 98368 • 360-385-1773 Looking N from Flag 3 to Enhancement Area Molotsky Wetland Delineation, Revised 2009-08-26 p. 10 of 35 Natural succession of plant species will take place within the identified enhancement area after mowing is ceased there, however the possibility of dominance by invasive species may delay the return of native trees and shrubs. Therefore a planting plan of native trees and shrubs has been designed to help establish more vertical structure and shade that can suppress some colonizing invasive plants such as Himalayan blackberry and reed canary grass. Desired vegetation in the restoration area consists of any volunteer native species that regenerate and a list of species for planting. Species were selected to match similar local seasonal wetlands and for characteristics of direct sun, moist to dry soils and ease of establishment. Trees shall be spaced 14 feet on center and container shrubs 6 feet on center. Live stakes will spaced 4 feet on center. For 1,400 square feet of planting area, this coverage requires 7 trees, 16 container shrubs and 16 of each variety of live stakes. All plant installation will be done by hand with minimal ground disturbance. Natural colonization of Nootka rose (Rosa nutkana) is already occurring in the planting area. Species Common Name Form Quantity Size Populus tremuloides Quaking aspen tree 7 8-12" container Sa/ix scou/eriana Scouler's willow tree/shrub 16 live stake Rhamnus purshiana Cascara shrub 8 6-10" container Cornus sericea Red-osier dogwood shrub 16 live stake Lonicera involucrata Twinberry shrub 8 6-10" container Willow and dogwood live stakes will installed along the existing ditch where seasonal ponding is frequent with the other species planted in the drier parts of the enhancement area. The planting plan (Figure 9) will be used to guide the general placement of species, although actual location will be determined onsite based on small variations in soil and hydrology. 8.5. Invasive Species Control of invasive species is critical to the success of this restoration plan. Several aggressive non-native species are currently established onsite and could hinder the survival of native species. Hand removal of Himalayan blackberry and reed canary grass around planted trees and shrubs may be necessary to keep them from being overtopped and smothered. A weed trimmer can be used to prevent smothering of planted trees and shrubs by trimming athree-foot radius around them as needed. Weed trimming may also be used to control invasive Canada thistle by repeatedly chopping it before it can flower and spread seed. Nootka rose and spirea (SpiYaea douglasii) can be aggressive colonizers but are beneficial native species and should be allowed to spread except where threatening to smother or overtop planted individuals. Then limited trimming may be needed during the monitoring period. The parcel has been mowed by tractor for hay annually. Mowing will be restricted in the reduced buffer, wetland area and enhancement area north and east of the house on the west side of Ditch A (see Mowing Restriction Area, Figure 7). Mowing elsewhere is desired to help control invasive species. Invasive species control within the Mowing Restriction Area may be done by hand according to the guidelines in this plan.

Monitoring Regular monitoring of the restoration area must be done at yearly intervals to insure that performance standards are met. Monitoring will be performed by the project biologist in early fall of each year of a 5-year monitoring period. Observations of plant species, plant size and health in the restoration area will be recorded. At least two photopoints will be established and photos shall be taken yearly and submitted with a monitoring report that shows the enhancement area and plantings. 8.7.Implementation Schedule and Performance Standards The 5-year monitoring period will begin after plants are installed following construction. The following schedule should be implemented once the enhancement plan is approved: Date Task Standard Summer 2009 Mark onsite buffer boundaries Install silt fence city inspection Control invasive species Fall 2009 permitting/construction city inspection Summer 2010 Control invasive species Fa112010 Planting Provide as-built drawing and photo of plantings Summer 2011 Control invasive species water plantings Fall 2011 Provide monitoring form to city Replace dead plantings as needed Summer 2012 Control invasive species water plantings Fall 2012 Provide monitoring form to city Replace dead plantings as needed Summer 2013 Control invasive species water new plantings as needed Fall 2013 Provide monitoring form to city Replace dead plantings as needed Summer 2014 Control invasive species water new plantings as needed MichaelB.DawsonCc~gmail.com • 1361 51St Street • Port Townsend • WA 98368 • 360-385-1773 Molotsky Wetland Delineation, Revised 2009-08-26 p. 12 of 35 Date Task Standard Fall 2014 Provide monitoring form to city Replace dead plantings as needed Summer 2015 Control invasive species 20% cover water new plantings as needed Fall 2015 Provide monitoring form to city 80% survival Implement contingency plan if standard is not met 8.8. Maintenance and Contingency Plans Weeding and weed control shall be done by hand. No herbicides or chemicals shall be applied in the enhancement area. Watering of planted individuals in the enhancement area should be done for at least two years after planting during the drier months of the year to help during the establishment phase. Watering may also be needed in subsequent years for any replantings done because of mortality or because of particularly dry conditions or slow plant establishment. Heavy browsing by deer or other herbivores may threaten survival of planted species, although smaller amounts of browsing are generally tolerated by plants after transplant shock is over. If heavy browsing causes mortality, temporary fencing or stem protection (in the case of voles) may be needed during the monitoring period. See 9. Resources, below, for help with plant identification and invasive species control. Trimming or mowing in 3-foot radius circles around each planted tree and shrub may be necessary during the 5-year monitoring period to prevent smothering by other vegetation. Greater than 20 percent mortality of native species in the restoration area or greater than 10 percent cover of invasive species shall be reason to implement a contingency plan. Failure to control invasive species below 20 percent cover of the enhancement area may jeopardize the reestablishment of native vegetation. The contingency plan shall be determined by Development Services staff or a qualified biologist. 9.
