Four wet areas have been or are proposed to be filled. Wetland A along Sixth Street and a portion of a Type V stream have been filled. The north end of Wetlands E and F, crossed by Mecklem Avenue, are to be filled. The Wetland A fill is 4,024 square feet. The Mecklem Avenue crossing of Wetland E is 1 ,902 square feet and will require approximately 200 yards of fill. The Mecklem Avenue crossing of Wetland F is 6,114 square feet, requiring approximately 680 cubic yards of fill. The Crogan Ave. crossing of a Type V stream is 200 sq. ft. A total of 12,240 sq. ft. of filled wetlands require 24,480 sq. ft. of new wetlands. A total of 25,250 sq. ft. is available for mitigation at the proposed site. Based on the Cowardin Classification System, Wetland A and Wetlands E and F, including the off-site portion, are palustrine forested wetlands. The on-site portions of the wetlands have been logged, leaving a palustrine scrub/shrub canopy. According to the Washington State Rating System, Wetlands E and F are a Category II wetland. Wetland A is a Category III. • The seasonal stream is a Type V stream. The main goal is to replace filled wetlands with one-half acre created wetlands. Additional goals include: 1 . Create soil conditions conducive to the formation of hydric soil 2. Provide wetland hydrology 3. Plant the created wetland with native species 4. Create forested wetland community The wetland mitigation area on Blocks 22 and 23, between Wetlands E and F. This area is chosen over a southern site due to soil disturbance and hydrology issues. The selected mitigation area has relatively undisturbed soils and ready sources of hydrology. A sample planting plan provides an example of the plant types and density. This is a preliminary mitigation plan with preliminary drawings. Upon approval of this report final drawings, specifications and calculations will be provided. • 3016M Rf/ajb/smh/7/13/00 • TABLE OF CONTENTS 1 .0 Introduction 2.0 Preliminary Wetland Mitigation Report 2.1 Executive Summary (see preceding page) 2.2 Project Description 2.2.1 Project Location 2.2.2 Responsible Parties 2.2.3 Description of Overall Project 2.2.4 Wetland Delineation 2.3 Ecological Assessment of Impact Site 2.3.1 Existing Vegetation 2.3.2 Existing Water Regime 2.3.3 Existing Soils 2.3.4 Existing Fauna • 2.3.5 Functions and Values 2.3.6 Water Quality 2.3.7 Buffers 2.3.8 Wetland Rating 2.3.9 Position and Functions of Wetland in Landscape 2.4 Mitigation Approach 2.4.1 Mitigation Sequencing 2.4.2 Goals and Objectives 2.4.3 Performance Standards 2.5 Proposed Mitigation Site 2.5.1 Site Description 2.5.2 Ownership 2.5.3 Rationale for Choice 2.5.4 Ecological Assessment of Mitigation Site 2.5.5 Constraints • • 2.6 Final Site Plan 2.6.1 Site Survey/Topography 2.6.2 Water Regime 2.6.3 Soils 2.6.4 Landscape Plans 2.6.5 Construction Specifications 2.7 Monitoring Plan 2.7.1 Vegetation 2.7.2 Water Regime 2.7.3 Soils 2.7.4 Fauna 2.7.5 Development of Habitat Structure 2.7.6 Water Quality 2.7.7 Buffers 2.8 Site Protection 3.9 Maintenance and Contingency Plans 3.10 Implementation Schedule 3.10.1 Construction Specification 3.10.2 Monitoring Schedule 3.10.3 Reporting Schedule 3.11 Performance Bond 3.12 Additional Information for Preparation of Final Plans 4.0 As-Built Report • LIST OF FIGURES: Figure 1 : LOCATION MAP Figure 2: U.S.G.S.

The format for the report follows the Annotated Outline as presented in the table of contents of the above referenced publication. This report addresses the mitigation for the filling of portions of Wetlands A, E, F and the Type V stream. 2.0 Preliminary Wetland Mitigation Report 2.1 Executive Summary 2.2 Project Description 2.2.1 Project Location Project Name, Jurges Enterprises of Plat of Detroit #2, Grapeview, Washington Location of wetlands is shown on Figure 1 , with latitude and longitude. Wetlands D through F, on the north and south parcels, are one contiguous wetland greater than five acres. The USGS National Wetland Inventory Map shows the watershed (Figure 2). The site map shows the north and south parcels at a scale of 1"=150' (Figure 3). National Wetland Inventory Map (Figure 2). Reference points for orientation in the field include existing roads, culverts, and tree-lines. 2.2.2 Responsible Parties Glen Jurges, PE Jurges Enterprises, Inc. 2020 Enetai Beach Bremerton, Washington 98310 360-377-0274 3016mrf2 . Consulting firm: A.J. Bredberg B&A, Inc. 3303 43rd St. NW Gig Harbor, Washington 253-858-7055. 2.2.3 Description of Overall Project The overall project consists of mitigating for previous activities that disturbed existing Wetland A and the Type V stream and proposed activities requiring filling of a portion of Wetlands E and F for road crossings. Proposed construction includes construction of roads on existing platted streets, new wetlands in designated mitigation areas and single family housing units. Four areas of wetlands have been or are proposed to be filled. Portions of Wetland A along Sixth Street and the Type V stream have been filled. The north ends of Wetlands E and F, crossed by Mecklem Avenue. The Wetland A fill is 4,024 square feet. The Mecklem Avenue crossing of Wetland E is 1 ,902 square feet and will require approximately 200 yards of fill. The Mecklem Avenue fill of Wetland F is 6,114 square feet, requiring approximately 680 cubic yards of fill. Crogan Ave. crossing the Type 5 stream is 200 sq. ft. A total of 12,240 sq. ft. of filled wetlands require 24,480 sq. ft. of new wetlands. A total of 25,250 sq. ft. is available for mitigation at the proposed site. The wetland areas to be filled will be mitigated by the construction of a new wetland, at a 2:1 ratio, on Blocks 22 and 23 of the northern parcel. Steps Taken to Avoid Impacts Steps to avoid impacts include minimizing impacts of wetlands by using existing platted roads which avoid wetlands to the maximum extent possible. Access to the majority of the building sites can not be made without impacting some existing wetlands and buffers. The following alternatives were evaluated. Access to blocks 25 and 26 were evaluated using: 3016 M Rf2/ajb/7/13/00 2 a) 9" Street via Atwater and Congress Avenues which has a significant impact on wetland D and buffers. b) 9th St. via Crogan Ave. impacts a minimum of 720 ft. of wetland D buffer and requires constructing a road through undisturbed forested property (between blocks 26 and 27, 41 and 42, and 43 and 44). Blocks 41 and 42 are not owned by Jurges Enterprises. c) 10th St. has insufficient width (15 feet) to construct an all weather road across blocks 42 and 43. d) Access via Oak St. from the north would require an equal or greater impact on wetlands E and F and buffers than via Mecklem Ave. Best Management Practices (BMPs) will be implemented to prevent degradation of water quality of the remainder of Wetlands A, E, F and the Type V stream. Water quality functions will be replaced. Flood storage of Wetlands A, E, F and the Type V stream will be offset by the construction of the replacement wetland in the northern tract. The remainder of the wetlands will have flood storage • unimpacted. Aquifer recharge and discharge of the wetlands will be unimpacted as the wetlands do not actively recharge an aquifer as they are underlain by relatively impermeable materials. The disturbed wetlands do not serve as aquifer discharge zones as they are not supplied water by springs or seeps. Aquifer recharge and discharge will be unchanged. Aesthetic, recreation and cultural value of Wetlands A, E, F and the Type V stream to be filled, will be replaced in the wetland mitigation area in the northern parcels at a ratio of 2:1 . Fish and wildlife habitat of Wetland A, the Type V stream, and the wetland crossings of Wetlands E and F, in the northern parcel, will be impacted and replaced in the wetland mitigation in the northern parcel. Whereas, no fish habitat is present in any of the wetlands to be disturbed nor in the stream, there will be no change to the fish habitat function. The value of the wildlife function will be increased through the enhancement plantings of the wetland, which were previously logged. The wetland crossings for Mecklem Avenue in the northern parcel will be replaced through creation of a new 3016MRf2/ajb/7/13/00 3 wetland and enhancement over existing logged conditions. Fish habitat will be unchanged. Wildlife habitat will be enhanced over existing conditions. Stream flow maintenance functions will be unimpacted by the proposed activities. The Type V stream is a seasonal stream. Wetland A does not support stream flow, whereas the northern wetlands, E and F, along Mecklem Avenue provide some storage for stream flow maintenance. Wetlands E and F flow to the stream, discharging to the east under Grapeview Loop Road. All the directly impacted wetlands will be mitigated on the northern parcel replacing stream flow maintenance functions. Stream flow maintenance will be replaced. Economic functions of the wetlands will be will be unchanged over existing conditions. Educational functions of the wetland will be unchanged as we are replacing in kind and in the same drainage basin. 2.2.4 Wetland Delineation A 24 inch by 36 inch base map at 100 scale is provided, showing topography and the wetland delineation. Figure 3 shows the wetland boundaries at 150 scale, while Figure 3A shows Wetland A and Figure 3B shows Wetland E and F. Please note that Wetlands E and F are portions of the same larger wetland D basin off-site to the south. Wetland boundaries were surveyed by a licensed land surveyor. The wetlands were delineated using the 1997 Department of Ecology Wetland Delineation Manual. The routine methodology was used in the undisturbed areas, while disturbed site methodology was used in those areas showing disturbance. Wetland boundaries were flagged on the southern wetlands on November 10, 1998. The northern wetlands were delineated on July 17, 1999. Data sheets are in Attachment A. Reference material used included the National Wetland Inventory Map, 1995 aerial photographs, and a map of the parceled blocks of the Plat of Detroit #2. 3016MRf2/ajb/7/13/00 4 . 2.3 Ecological Assessment of Impact Site 2.3.1 . Existing Vegetation Based on the Cowardin Classification System, Wetland A and Wetlands E and F, including the off-site portion, are palustrine forested wetlands. The on-site portions of the wetlands have been logged, leaving a palustrine scrub/shrub canopy. Figure 5 is a sketch map showing the distribution of the palustrine forested, palustrine scrub/shrub, palustrine emergent and riverine plant communities. There was no seasonal difference in the dominant plant communities. TABLE 1: Plant populations Wetlands A, E and F off-site and on-site Trees Indic Relative ator abundan Statu ce s Western red cedar FAC 50% Red alder FAC 40% Black cottonwood FAC 10% W Shrubs Black cottonwood FAC 20%* W Red alder FAC 10%* Salmonberry FAC 100%,10 oho* Emergent Cattails OBL 10%* Small fruited bulrush OBL 10%* Soft rush FAC 20%* W * on-site populations Relative abundance of the dominant and subdominant plants in each community are outlined below. The wetlands lack a large distribution of exotics. 3016MRf2/ajb/7/13/00 5 Vegetation structure of adjacent upland plant communities and those areas unlogged is a forested plant community. In the logged areas the plant community is scrub/shrub. 2.3.2 Existing Water Regime Source of water for the wetlands is ambient rainfall and groundwater running parallel to the dense basal till . The rainfall either surface flows into the wetland or infiltrates the ground and travels laterally across the dense basil till subsoil where it emanates in the wetlands at the break of slope at the edge of the wetlands. The Type 5 stream provides hydrology to Wetland D. Duration and frequency of inundation and/or saturation varies with the wetland. Figure 2 is a map of the drainage area with flow directions. The surface and subsurface water was measured in the summer and winter months. Wetlands A and E had no saturation in the summer months, while the surface was saturated in the winter months. Wetland F had saturation in the center portion of the wetland to within 12 inches of the surface during the summer months, while the outer edges of the wetland were not saturated during the summer. During the winter, all of Wetland F was saturated to the surface. The description of the monitoring involves digging an 18 inch hole by hand and allowing water to equilibrate. 2.3.3 Existing Soils The soil of the wetlands most closely matches that of the Norma series. All of the wetlands tend to have a thick, dark surface horizon (10YR 2/2 to 10YR 2/1) consisting of a silt loam to very fine sandy loam. This overlays a gray (10YR 4/2) sandy loam B horizon. The structure of the surface horizon was a granular structure, while the B horizon was massive. The permeability of the soils is moderate to moderately slow. The organic content of the surface horizon approaches 5%, while the subsoil is less than 1% organic matter. The upland area slated for wetland creation has soils generally matching the Harstine series. The soils generally have about 6 inches of dark grayish brown (10YR 3/2) over a brown (10YR 4/3) i and yellowish brown (10YR 4/6) B horizon. 3016MRf2/ajb/7/13/00 6 2.3.4 Existing Fauna The animal community using the wetlands and buffers is an animal community typically found in the Pacific Northwest. It should be noted that an eagle perch tree is located off-site on the western edge of Block 44. Other wildlife using the site would include red tailed hawk, deer, coyote, raccoon, black bear, and other mammals typically found in the area. There is no evidence of beaver use, past or present, on the site. In addition to those mentioned, bird use includes common crow, various water fowl, and a variety of songbirds. It is anticipated that numerous amphibians would use the property, including frogs and salamanders. There is no evidence of fish use on the subject property. 2.3.5 Functions and Values The Washington State Wetland Rating System was used to classify the wetlands on the subject property. Wetlands E and F are one large contiguous wetland rated as a Category II wetland. Wetland category sheets are attached in Attachment B. Wetland A is rated as a Category III wetland. Water Quality: The wetlands improve water quality in the watershed by slowing, detaining, and filtering out sediments and pollutants prior to discharge into the stream flowing in a northeasterly direction. Habitat for Plants and Animals: The wetlands function as habitat for plants and animals by providing an undisturbed corridor through the property. The wetlands are part of a larger system with contiguous forested property to a large tract of timber land to the west. As previously mentioned, an eagle perch tree is located in Block 44 and is labeled as such on the map. There are no other known priority wildlife species on the subject property. There are no other know priority habitats on the subject property. Storing Flood Water and Reducing Peak Flows: The wetlands function to detain water, thereby reducing peak flows and minimizing the amount of flood water. The close proximity of the wetlands and stream to the Puget Sound and relatively small watershed supplying the stream minimize the potential for flooding. 3016M Rf2/aj b/7/13/00 7 . Ground Water Recharge and Discharge: The wetlands provide a minimal amount of groundwater recharge as they are underlain by dense basil till. The dense basil till is relatively impermeable perching the water on top. The wetlands are supplied by ambient rainfall seeping along the dense basil till hardpan. The water daylights where it seeps out at the toe of slope at the edge of the wetlands. The seeps are not deep seated seeps as they tend to dry out in the summer and do not provide year round flow. Recreation and Educational Opportunities: The recreation and educational opportunities offered by the wetlands include areas for bird and animal watching and hiking. 2.3.6 Water Quality The wetlands provide a sink for suspended solids, thereby removing sediments from the water. The wetlands are heavily vegetated and tend to filter out suspended solids from the surrounding upland areas. Nutrients • The nutrient content of the water has not been measured. Fecal coliform Fecal coliform of the water should be low, as the watershed lacks development. Furthermore, there is no livestock within the watershed to supply fecal coliform. The only fecal coliform is likely to source from the droppings of wildlife. Heavy metals in water and sediments As the watershed is historically undeveloped in the past fifty years, there should be a minimal amount of heavy metals in the water and sediments. No sampling has been done to verify this. 2.3.7 Buffers The buffers of Wetland A are cut off to the west of Wetland A by Sixth Street. The off-site buffer of Wetland A is a mixed forested of deciduous and conifer trees. The buffer contains western red cedar, Douglas fir, and red alder. The diameter of breast height (DBH) of the buffer is between 8 and 30 inches. The undergrowth of the buffer is dense with a few snags, heavy canopy coverage, and some 3016MRf2/ajb/7/13/00 8 downed woody debris. Figures 4 and 5 provides a map of the buffer areas and vegetation types for Wetlands E and F. Wetlands E and F have buffers that have been logged and stumped. The regrowth is scrub/shrub vegetation of red alder, salal, Oregon grape, western red cedar shrubs, brackenfern, and red alder saplings. 2.3.8 Wetland Rating According to the Washington State Rating System, Wetlands E and F are a Category II wetland. Wetland A is a Category III. The data sheets are provided in Attachment B. 2.3.9 Position and Functions of Wetland in Landscape The wetlands are classified according to the hydrogeomorphic classification (Brinson, 1993). Wetland A is a ground water depression. Wetland A attenuates flooding by retaining water and preventing it from reaching nearby streams. It does not serve as a wildlife corridor between different regions of the watershed as it is surrounded on all sides by clearings, streets, or single family residences. It is not a part of a regional flyway as it does not provides habitat for migratory water fowl. Its regional value for the improvement of water quality is low as it has low flow through. The large wetland that constitutes Wetlands E and F are ground water slope wetlands at the outer edges and low gradient non- alluvial riverine wetlands at the center of the wetlands. Their role in attenuating flooding is high as the low gradient non-alluvial riverine portion detains water and decreases the opportunity for flooding. However, keep in mind that the stream is within a few hundred feet of discharging into the Puget Sound, thereby flooding is a non-issue. The large wetland is a corridor for wildlife between different regions of the watershed as the wetland is a large forested area relatively undisturbed leading to a large area of forest land to the west. The wetland has low value in the forested area as a regional flyway as the wetland is inaccessible due to the heavy growth of forest. • 3016MRf2/ajb/7/13/00 9 • 2.4 Mitigation Approach 2.4.1 Mitigation Sequencing The main strategy for avoiding impacts altogether involves foregoing development of the lots encumbered by wetlands. Several of the blocks of platted lots are encumbered by wetlands and no development is proposed within those blocks. Likewise, no road access to those lots is proposed. Methods that were considered to minimize wetland impacts on-site included redesigning as narrow a road as possible through the impacted areas. Road layout has also been placed such that the minimal amount of wetlands as possible will be impacted. Several of the existing platted roads will not built, thereby avoiding wetland impacts. Wetland rectification strategies involve replanting impacted wetlands, replanting impacted buffers, and creating new wetlands to mitigate for the wetlands and the Type V stream filled or to be filled. Wetlands and buffers will be protected with conservation easements • or similar covenants. Road construction will be performed in the dry seasons to minimize impacts during construction. 2.4.2 Goals and Objectives Replace filled wetlands with one-half acre created wetlands 1 . Create soil conditions conducive to the formation of hydric soil 2. Provide wetland hydrology 3. Plant the created wetland with native species 4. Create forested wetland community Approximately 24,480 sq. ft. of palustrine forested wetlands will be created to mitigate for the filling of approximately 12,240 square feet of scrub/shrub wetlands and Type V stream. The functions and values shall be restored to create, enhance or preserve are as follows: • 3016MRf2/ajb/7/13/00 10 • The wetland functions will be restored as follows: Water quality The new wetland will create conditions conducive to maintaining water quality that will include the removal of pollutants and sediments. The new wetland will create an excavated area that will have flood storage. Aquifer recharge and discharge The wetland will be placed on the landscape where it will have groundwater seeps which will be an area of shallow aquifer discharge. Aesthetic, recreation, and cultural functions will be replaced by creation of a palustrine forested wetland with a diverse canopy of shrubs and trees. This will replace the aesthetic value as it grows and provide equal or greater recreational value than those wetlands filled. The cultural value will remain unchanged. Fish and Wildlife • Whereas, there is no fish habitat in any of the wetlands to be filled, the fish habitat will be unimpacted. The wildlife habitat of the created wetland will be equal to or greater than those areas of filled wetlands. It is likely to be greater than those areas filled because existing conditions do not have a diverse regrowth of native species. The replanted area will have a diversity of species not available in the areas to be filled. Stream Flow Maintenance The new wetland will have similar stream flow maintenance as the filled areas. It will have a greater opportunity for stream flow maintenance as Wetland A is a depression and has no connection to a seasonal stream. The filling of Wetlands E and F are at the upper end of the wetland and a similar area will be created in a similar landscape position. Filling 200 sq. ft. of the Type V stream has minimal impact on stream flow maintenance. Economic The economic value of the filled wetlands to the created wetlands will be unchanged. 3016MRf2/ajb/7/13/00 I • Educational Value The educational value of the created wetlands will be higher as they will be an example of how wetlands can be filled and replaced with enhanced wetland over existing conditions. 2.4.3 Performance Standards Replace filled wetlands with one-half acre created wetlands 1 . Create soil conditions conducive to the formation of hydric soil Soils in the replacement wetland will be excavated and replaced to promote the creation of hydric soil conditions. The surface elevation will be lowered to provide saturated soil conditions. Test holes will be dug and soils described to 18 inches to verify the establishment of hydric soils. 2. Provide wetland hydrology Hydrology of the replacement wetland in the northern blocks will be verified in the early spring of the year. The area will be evaluated to determine if saturation is within 12 inches of the surface and wetland hydrology criteria are met. 3. Plant the created wetland with native species Performance standards shall be based on percent plant survival and percent aerial coverage. At each of the monitoring visits and at the end of the three year monitoring, there shall be an 90% survival rate of planted species in the wetlands and buffers. At the end of three years there shall be 80% aerial coverage. 4. Create forested wetland community The tree plantings shall have a survival and growth confirmed that a forested plant community will eventually form. This will be verified on the monitoring sheets. 3016MRf2/ajb/7/13/00 12 • 2.5 Proposed Mitigation Site 2.5.1 . Site Description and Pertinent Location Information The site is located in the southeast quarter of the northwest quarter of Section 5, Township 21 N, Range 1 W of the Willamette Meridian. Latitude and Longitude is N470 20.37' and W1220 50.20. The combined total for the northern and southern parcels is approximately 38 acres. The USGS Map is shown (Figure 2). A site map accompanies, showing the site at 100 scale and Figure 3 shows the site at 150 scale. Impacted areas of the Type V stream and Wetland A is about 950 feet from the mitigation site, while Wetlands E and F to be impacted are 100 and 200 feet respectively, from the mitigation site. The 1997 Department of Ecology Wetland Delineation Manual was used to delineate the wetlands. The routine methodology was used, except in those areas where the site was disturbed, in which case disturbed site methodology was used. Figures 3A and 3B are wetland maps for the on-site portion of the wetland; Figure 3 shows the off-site portion and estimates the locations of wetland and streams. 2.5.2 Ownership The property is currently owned by Glen Jurges, the applicant. The applicant will be responsible for the site in perpetuity. There are no water control structures associated with the property. 3016MRf2/ajb/7/13/00 13 . 2.5.3 Rationale for Choice One area of mitigation is proposed: On the northern parcel, a wetland area will be created between and on Blocks 22 and 23, as shown on Figure 6 for the following reasons: • The area chosen for the mitigation site on Block 23 is in a natural landscape position equivalent to the wetlands on either side. • Topsoil and subsoil can be stockpiled and restored to create a potential hydric soil for the created wetland. • Test holes were dug verifying the relatively undisturbed status of the mitigation area. • The mitigation area on Block 23 is not an area of fill. • The northern mitigation site is in the same watershed as Wetland A and the Type V stream of the southern parcels. • The properties abut the same wetland basin. • The mitigation location is considered on-site for both the north and south properties. • Regardless of the location for mitigation of Wetland A, there will be the current location of mitigation for crossing Wetlands E and F. • The north and south parcels are considered a single and complete project. • The ownership of the north and south parcels are the same. • The stop work order addresses the north and south parcels as one parcel and one project. Other potential mitigation locations in the southern parcel were evaluated and found to be much less desirable when compared to the possibility of a location on Blocks 56 and 57. A portion of Block 56 and 57 has been evaluated for potential wetland restoration but has been ruled out in favor of the northern site on Block 23 for the following reasons: • Blocks 56 and 57 are an unnatural landscape, having been completely reshaped. 3016MRf2/ajb/7/13/00 14 . • The soils are highly disturbed, where the buffer currently exists, and not conducive to creating a successful wetland mitigation area (Attachment C and Figure 13). • There is no ready source of hydrology on the Blocks 56 and 57 necessary to support wetland hydrology of an expanded wetland. • There is no topsoil and thus no seed source in the soils on Blocks 56 and 57. • A portion of this buffer has been replanted and is currently regrowing as an effective buffer. • If this area were used for wetland mitigation a functional buffer would be lost. • Access to Block 43 and the other blocks to the north, not owned by the applicant, can only be accessed via 9tn St. Constructing the replacement wetland along 9tn street would put part of the replacement wetland and much of the buffer in the only access to Block 43 and the other Blocks to the north. A potential wetland mitigation area on Blocks 56 and 57 has been regraded, removing all top soil and leaving dense basil till materials, and it not conducive to plant growth. Soil logs were recorded in this area (Attachment C). If this area were to be reconstructed as a wetland mitigation area, there would be no topsoil or subsoil available to create conditions conducive to a wetland. This is in contrast to the mitigation area on Block 23, where topsoil and subsoil can be stockpiled and restored to create a potential hydric soil for the created wetland. The mitigation area on Block 23 is not an area of fill. The soils of the Block 57 area contain no seed source for replacement to create a wetland plant community. This is in contrast to the area of Block 23 where the topsoil has a seed source that, when replaced, will provide regrowth. The area on Block 57 that is now the 85-foot buffer does not have a ready source of hydrology. There is no indication that hydrology would support a wetland if created in this area. This is in contrast to the area on Block 23 that has wetlands on either side. Having wetlands on either side assures that hydrology would be present in the created area. • 3016MRf2/ajb/7/13/00 15 It is recommended that the wetland mitigation area be on Block 23 of the north parcels for the following rationale: Enough water at the right time of year will be available for the wetland mitigation area as either side of the wetland mitigation area contains hydrology in the spring of the year to create wetland conditions. The mitigation area will be excavated to a depth that will allow hydrology to be present as it seeps into the area from the uplands to the north just as seepage provides hydrology to the wetlands on either side. Adequate buffer to protect the wetland and functions will be provided between proposed Mecklem Avenue and the created wetland. On three sides, the created wetland will be protected by the existing wetlands. Soils in the proposed mitigation area can be modified to create wetland soil conditions. The upper two feet of soil will be stockpiled, the A horizon and B horizon respectively, and the subsoil will be excavated dropping the mitigation area two feet with the B horizon and A horizon replaced respectively to • create a lower landscape position to provide wetland hydrology. As wetland hydrology is established in the mitigation area, hydric soils will form. Adjacent land use to the mitigation area as wetlands will be protected by covenant. To the north will be Mecklem Avenue which will have a buffer separating the street from the mitigation area. 2.5.4 Ecological Assessment of Mitigation Site Adequate hydrology will be provided to support the wetland in perpetuity, via the ground water that will daylight in the wetland area. The proposed mitigation area is located between two wetlands that currently have wetland hydrology. The location chosen for the new wetland is in a similar landscape position has wetlands on either side. By excavating down, the water table along the dense basil till subsoil will be intercepted and used to maintain adequate hydrology in the proposed mitigation area. 3016 M Rf2/ajb/7/13/00 16 A level spreader swale will be located at the north end of the proposed mitigation area. Water from Mecklem Avenue will be diverted through the roadside ditch into the level spreader swale to provide hydrology for the new wetland. The roadside ditch will be vegetated as will the ditch running through the buffer carrying the water. The vegetated ditches will act as bio-swales providing clean water to the wetland. Description of Experience With This Type of Mitigation 1 . This type of mitigation has been done successfully before 2. The consultant has experience with this type of work both in size and technical difficulty 3. References for similar mitigations that have been completed: ARCO Site, Graham, Washington Wal*Mart Store, Shelton, Washington Senior Housing, Snohomish County, Washington Lee Estates, Snohomish County, Washington Exotic species including reed canarygrass, purple loose strife will be controlled through hand-weeding and spot application of approved herbicides. Wetland functions at the site after all performance standards have been met are as follows: Water Quality The wetland will receive treated surface runoff from Mecklem Avenue. The wetland will have adequate detention and retention such that it will remove sediments and pollutants from road runoff. Flood Storage The new wetland will be created with areas of dead storage that provide flood storage functions above and beyond existing conditions. Aquifer Recharge and Discharge The area will have minimal aquifer recharge as it is underlain by dense basil till hardpan. The area will have a slight • discharge as the water flowing parallel to the dense basil till hardpan will daylight into the wetland. 3016 M Rf2/aj b/7/13/00 17 Aesthetic, Recreation, and Cultural Value The area will have functions for this value as it will grow into a forested wetland with a diverse canopy of scrub/shrub and forested plant community. Fish and Wildlife The wildlife habitat of the replaced wetland will function as a diverse habitat providing food source and nesting cover. The fish habitat will be minimal, however, there will be water quality benefits for the downstream discharge to Puget Sound. Stream Flow Maintenance The wetland will retain water into the spring and summer months and release it slowly to the stream off-site to the south. Economic The economic value of the wetland will consist only of non- tangible increases. The non-tangible increase will have to do with the other functional values that have been increased over existing conditions. Education Educational value of the replacement wetland will be high as it is an example of a replacement area for disturbed wetland sites. Buffers of the proposed mitigation area includes existing wetlands on three sides. There will be an additional 85-foot buffer north to Mecklem Avenue that will be planted with enhancement plantings. Grading of the northern portion of the wetland will be a cut that will be replanted with native vegetation as part of the buffer. In addition, grading will provide a level spreader swale at the edge of the wetland channeling runoff from Mecklem Avenue into the wetland. The wetland will be located such that it is part of a corridor along existing wetland boundaries. The land use of the proposed area adjacent to the mitigation site will be the construction of Mecklem Avenue and establishment of single family residential lots. The existing wetlands on three sides of the proposed mitigation area will be left in perpetuity. The wetland 3016MRf2/ajb/7/13/00 18 mitigation area will be included in the construction plans for Mecklem Avenue to receive runoff to provide hydrology. Based on experience from previous projects, this project will include many future improvements similar to the Oakdale development to the north. The project will include the construction of streets to access the existing platted lots. Other improvements include on-site septic disposal and wells to serve the single family residences. Habitat improvements will be a 2:1 replacement of impacted wetlands and an increase in many functions over existing conditions. Improvements to the created wetland system will include enhancement plantings as well as grading to provide dead storage for storm runoff. The new wetland will receive runoff from the proposed street. Runoff will be treated, such as biofiltration, prior to discharge into the wetland. 2.5.5 Constraints Constraints outside the owner's control that might affect the mitigation site include: There may be a heavy invasion of exotic species to be controlled. Whereas, the site has already been logged for most of the buffer around the property, the only area that could potentially be logged is southeast of the proposed mitigation area. Uncontrolled stormwater runoff from the Oakdale project to the north flows onto the proposed mitigation area. There are no other constraints that would interfere with the construction and maintenance in perpetuity of the wetland mitigation area. 2.6 Preliminary Site Plan Following is a list of information relevant to the construction of the replacement wetland in Blocks 22 and 23. Figure 7 is a schematic drawing of changes in topography of the wetland • mitigation area. 3016MRf2/ajb/7/13/00 19 Figure 8 is a schematic drawing of the location of the ditches feeding the level spreader swale, and Figures 9 and 10 are level spreader details. Figure 11 is a schematic drawing of the proposed vegetation distribution and structure. It includes an overview as well as a cross-section. Changes to habitat attributes will occur throughout the wetland planting area with the mitigation plantings. Figure 4 shows location of proposed buffers. Figure 12 is a cross-section drawing showing the relationship of topography, hydrology and vegetation. Methods used to meet the objectives are as follows: To create soil conditions conducive to the formation of a hydric soil, the mitigation area will be lowered in elevation to allow for wetland hydrology to form. With the formation of wetland hydrology, hydric soils will form over a period of time. Wetland hydrology will be provided by excavating the area to lower elevation to intercept the perched water table. In addition, water from the uplands to the north will be diverted and channeled into the subject area through a level spreader swale. Additional earth work within the wetland will configure the area to trap water in various stages down through the wetland moving downslope. The wetland mitigation area will be planted with native species. The native plants will be planted using Best Management Practices (BMPs). Forested wetland will be created by the choice of numerous tree species in the planting plan. 2.7 Monitoring Plan Variables measured Wetland Creation Area Monitor soils for proper placement in horizon sequence, and later for the formation of hydric soils Verify presence of wetland hydrology Verify survival rate of native species 3016MRf2/ajb/7/13/00 20 Monitor growth of trees to verify the creation of a forested wetland Sampling methods for each of the variables are as follows: Vegetation success will be based on 90% survival. The sampling method used will involve establishing permanent 20x20 foot plots; four in the wetland mitigation area for verifying survivability of the species. There shall be 80% coverage at the end of the 5 year monitoring. Soils will be sampled using a hand shovel and digging approximately 18-24 inch hole to verify the proper horizonation of the soils. Later in the monitoring period, the soils in the wetland mitigation area will be dug to a depth of 24 inches to verify the formation of hydric soil factors. Use of wildlife will be verified by observing activities of wildlife within the wetland buffer and wildlife corridor along the stream. Observing the presence of tracks, feeding habits, and other activities of wildlife will verify this variable. sWetland hydrology will be verified by digging an 18 inch hole during the early growing season to verify that wetland hydrology is present. Sampling method for verifying a forest involves verification of 90% survival of the tree species planted. This will be done in the same method as the verification of the survivability of the native vegetation. Sampling locations for each variable will occur in the designated sample plots in each of the areas. Four permanent 20 ft. by 20 ft. sample plots will be established in the wetland mitigation area. The as-built report after the first sampling report for each of the variables will show the sampling plot locations. No laboratory methods will be used. Clearly identifiable markers on the ground will act as reference points for orientation to establish sampling locations. 3016MRf2/ajb/7/13/00 21 The monitoring will be prepared by B&A, Inc., 3303 43rd Street NW, Gig Harbor, Washington 98335. 2.7.1 Vegetation Vegetation monitoring will be done to measure the success of plantings and recolonization both in the wetland and in the buffers. Vegetation monitoring will be performed on 20x20 foot sample plots and total plant counts will be made. Vegetation monitoring will be twice yearly and per the monitoring form (Attachment D). The various strata will be monitored for the number of plants planted, plant condition, percent cover, and percent survival. All desirable volunteers will be noted. Included will be a count of invasive exotics, percent cover, and method of control. 2.7.2 Water regime The water regime in the replacement wetland area will be monitored through the digging of individual monitoring wells on each of the site visits in the early spring. Individual ground water wells will be dug at each of the site visits to monitor hydrology. The soils holes will be dug to a depth of 18 inches and the water table allowed to equilibrate. A measurement will be made and it is anticipated the water will be within 12 inches of the surface for two weeks of the growing season. 2.7.3 Soils Soil monitoring will be performed at each of the site visits as shown on the monitoring form (Attachment D). Soils to a depth of 18 inches will be documented and notes made of the formation of hydric soils. 2.7.4 Fauna The monitoring form provides space for comments on wildlife observed (Attachment D). A visual observation will be made of bird and mammal populations and use by birds and mammals of the sites. • 3016MRf2/ajb/7/13/00 22 2.7.5 Development of Habitat Structure The monitoring of the development of habitat structure will be included in the comments section of the monitoring form (Attachment D). The construction of the mitigation area will include the placement of logs and stumps. The following items will be noted on the monitoring form: • Tree structure in and around the wetland. • Density and size of snags, downed trees, and woody debris. • Canopy cover. • Number of structural levels and distribution. • Connection of mitigation area to aquatic and terrestrial habitats and other open lands. • Description of adjacent land use and their impacts on the mitigation site. • Presence of priority habitats. 2.7.6 Water Quality Water quality will not be monitored in this mitigation plan as it has not been an issue in the restoration or the mitigation of any area. 2.7.7 Buffers The buffer of the mitigation area will be monitored in the same manner as the wetland mitigation area is monitored. One sample plot will be placed within the buffer area. 2.8 Site Protection The buffers and wetland areas will be placed under protective covenants for protection in perpetuity. Conservation easements, deed restriction, or other similar protective covenant will be placed on the wetlands and buffers. Mason County will be relied upon for the preferred covenant to be placed on the properties. 3.9 Maintenance and Contingency Plans Maintenance of the property will be carried out by Robin Richie Madrona Point Landscaping. The maintenance schedule for the first year shall be on a monthly basis, which will include inspection of irrigation system and 3016MRf2/ajb/7/13/00 23 water structures. Plant replacement, weeding, fertilization, erosion control, plant protection, trash removal, and other activities will be performed on an as needed basis, per the monthly inspection. Maintenance will include the following: No broadcast fertilizers or pesticides will be used The success rate for the overall plantings will be monitored and replanting performed if necessary Supplemental watering will be applied in the first year to stressed plants Exotic or invasive, undesirable vegetation, such as Himalayan blackberry, reed canarygrass and Scot's broom shall be removed from the planting area Maintenance recommendations will be determined at the monitoring site visits A contingency plan is provided in case the mitigation should be unsuccessful or only partially succeeds. The contingency plan will take effect should the site be found at any of the site visits to be non conforming to the specified performance standards. Initiating Procedures If a performance standard is not met within the time specified, the mitigation plan and report shall be prepared analyzing the cause of the failure, propose corrective actions and present a time frame for implementing these actions. Minor corrective measures will be taken as part of the routine maintenance and will only be identified in the monitoring reports. Any problems will be reported in a timely manner, within two weeks of observance of the deficiency. Funding A contingency fund will be established with the county by way of the bond or other security device. Responsible parties A.J. Bredberg of B&A, Incorporated, 3303 43rd Street NW, Gig Harbor, (253) 858-7055, and Robin Richie madrona Point Landscaping, will be responsible for implementing and monitoring contingency procedures. 3016MRf2/ajb/7/13/00 24 . 3.10 Implementation Schedule 3.10.1 Mitigation Area Time Schedule Place silt fence around edge of mitigation area, August, 2000 and regrade area stockpiling topsoils and excavation mitigation area.

The following formula is to be used in the calculation of the bond. Upon approval of the final mitigation plan for the replacement wetland area, an estimate of construction cost, plant count, and plant installation will be known and the bond calculated. Table 2: Mitigation Bond Regrading $ Level spreader swale $ Plant materials $ Installation $ Overseeding $ + 20% $ Total $ Monitoring Year one $ Year two $ Year three $ Year four $ Year five $ Total $ 3.12 Additional Information Soil Preparation, Mitigation Area The mitigation area has relatively undisturbed native soils. There is a thick, dark, surface horizon over a brown B horizon overlaying a dense basil till hardpan. The topsoil, including the duff layer, will be stripped and stockpiled in one location while the B horizon will be stockpiled in a second location. This will expose the dense basil till hardpan which will be excavated approximately two feet and the material stockpiled in a third location. The soils will be replaced in the order of the B horizon replaced lining the bottom of the excavation, followed by the original topsoil replaced with a minimum of compacting. The soils will be replaced in a natural configuration providing a series of pits and mounds for the growth of vegetation with the trees on the mounds with the shrubs in the pits. 3016M Rf2/ajb/7/13/00 26 Once the soils have been replaced and shaped, logs and stumps will p be located in a natural configuration throughout the mitigation area. Standard Project Requirements Sedimentation control measures will be instituted prior to, during, and after construction to prevent erosion or sediment problems. Native species will be used for all new plantings. An As-Built report will be prepared after the planting has been completed to verify that it has been done according to plans. Monitoring plans on a yearly basis will be provided to Mason County Planning Department. Performance/maintenance assurance devices will be provided per the requirements of Mason County. Planting Plan The Planting Plan shows plant locations and spacing. Table 3 lists the species, quantities, sizes, and spacing. All plant materials will be from approved sources. Bare areas will be overseeded with a standard mixture (Tables 4 and 5). Materials Plants shall be free of disease, insects, insect eggs, larvae, weeds, weed seed, and other pests. Plants shall be first quality with normal roots, trunks, limbs, stems and shape, and labeled with genus, species and variety. The owners' representative has the right to reject non- conforming plants. The transplanted materials will be maintained and monitored. Suitable substitutions may be made due to availability, price, and condition of the plants only with county approval. 3016MRf2/ajb/7/13/00 27 • Planting and Seeding All plants will be pruned to remove dead and diseased branches prior to planting. The choice of plants should provide a combination of benefits to the wildlife habitat and benefits to the urban landscape environment. The plantings should be made between October and January. Plantings should be made following standard practices. Plants are to be placed in a natural orientation per the planting plan after major site work has been completed. When all work has been completed the owner's representative will inspect the work and grant acceptance. The plant warranty will become effective at this time for a period of one year. The contractor will be responsible for maintaining the area by weeding, watering, and replacing unhealthy plants. • This Ian should be used n'p ed in conjunction with the accompanying report by B&A, Inc. The liability by B&A, Inc. is limited to the payment received for preparing the final mitigation plan. The plantings will be performed by a firm or individual experienced with nursery and/or landscape work and all stock will be from approved sources. Plants shall be bare root, gallon container or other available media matching specified size. 4.0 As-Built Report An as-built report will be sent to the lead agency within a month of construction and planting completion, in November, 2000. The as-built report will contain: • 3016M Rf2/ajb/7/13/00 28 • As-built topography Photographs of established wetland taken from permanent reference points of the permanent field plots As-built plan of actual plantings, including density, size, source and time of planting Highlight any changes to the plan that occur during construction Habitat features actually installed and their locations Locations of sample plots The site will be inspected by a biologist to ensure compliance with the plan specifications during the construction and completion of construction. All goals and objectives of the design plan will be reviewed and verified when checking the completely work. If there are any changes to the plan, minor changes will be documented and reviewed. Major changes will require an amendment to the mitigation plan or approval by the agencies. Changes will be noted on the original construction so they will be easy to verify. • 3016MRf2/ajb/7/13/00 29 TABLE 3: WETLAND MITIGATION PLANTING MATERIALS Genus species (Common Name) Symbol Used Size Spacing TREES Acer macro h llum Bi leaf maple) BM 1-4' 12' Thu'a plicata Western red cedar RC 1-4' 12' Pseudotsu a menziesii(Douglas fir DF 1-4' 12' Tsuga heterophylla(Western hemlock) WH 1-4' 12' Po ulus trichocar a Black Cottonwood BC Whips 12' SAPLINGS Cornus stolonifera(Red-osier dogwood) RD 1-4' 6' Salix sp.

Seed establishment shall include the use of supplemental materials, such as mulch. * Site preparation-Install surface runoff control measures. * Seedbed Preparation may include the following: • a. If infertile or coarse textured subsoil will be exposed during grading, stockpile topsoil and respread it over the finished slope and roll it to provide a firm seedbed. b. If construction fills have left soil exposed with a loose,rough or irregular surface,track walk up slope. C. If cuts or construction equipment have left a tightly compacted surface, break with chisel plow or other suitable implement. Perform all cultural operations across or at right angles to the slopes (contoured). The seedbed should be firm with a fairly fine surface after roughening. * Fertilization-As per supplier's recommendations utilizing non-phosphorus mixtures. * Maintenance- Seeding should be supplied with adequate moisture. Supply water as needed, especially in abnormally hot or dry weather,or on adverse sites. Water application rates should be controlled to prevent runoff. Inadequate amounts of water may be more harmful than no water. * Re-seeding-Areas which fail to establish vegetative cover adequate to prevent erosion shall be re-seeded as soon as such areas are identified. 3016MRf2/ajb/7/13/00 33 Mag 13.00 � V 3U Wed Feb 02 10:39 2000 3 Scale 1:31,250(at center) 2000 Feet �---I ' Meters M l Pond C Secondary SR,Road,Hwy Ramp ash Lake State Route ®Primary State Route Olympic Shore — Railroad O Town,Small City I -Ocz Bay 7 Geographic Feature Pn( lo/ Pnlnt Locale ! - — County Boundary i I I I I I I j N470 20.37' W 1220 50.20 V . � or 1 / >✓u Aw fit& d y,&/ -- Grapeview Stretch Island Stadium--/ M lane t ove FIGURE l : LAT.
