Mitigation is required by the Jefferson County Code to compensate for wetland and buffer impacts caused by the driveway crossing. The mitigation for the proposed impacts will involve enhancement of historically cleared wetland and buffer at the south end as well as along the future driveway. Native vegetation has begun restoring the former forested community and this enhancement plan has been designed to supplement the native vegetation community that is developing. The impact area is roughly 63 feet long across the wetland and is 15 feet wide totaling about 945 square feet of wetland impact. The impact area includes the 12 foot wide driving surface and the road slope. The buffer impacts total roughly 2,400 square feet and mitigation will involve enhancement of the cleared forested buffer east of the enhanced wetland area and in the red alder forested western buffer along the future driveway, Creation is not proposed because there are no areas on-site where creation could take place due to slopes and existing native vegetation areas. It is also not proposed because this is a single family project that involves less than 1,000 square feet of wetland impact and the cost for enhancement are significantly lower than cost for creation of new wetland. The wetland is a forested mosaic system and the area of impact includes mostly emergent vegetation with about 8 red alder trees and 3 western red cedar trees on the upland hummocks, There is about 1,792 square feet of wetland lying just off-site north of the driveway that will be un-impacted by construction of the driveway, This area will not be negatively impacted by the road crossing because it actually provides a source of hydrology to the remainder of the wetland and there will continue to be drainage between the on and off-site wetland areas via the existing drainage that will be culverted under the future driveway (see site plan). The remainder of the wetland system is dominated by emergent vegetation (mostly slough sedge- Photos 1 and 12) with hummocks of salal and patchy areas of hardhack (Photo #13) in the southeastern portion. Enhancement of the wetland will involve installation of additional native tree and shrub species in about 9,831 square feet of the wetland, which exceeds the amount of wetland enhancement per the mitigation ratios of the Jefferson County Unified Development Code. Enhancement activities will also involve falling of removed trees from the impacted wetland to provide large. woody debris to the wetland for use by local wildlife species. Buffer impacts will also be necessary to facilitate driveway construction and will involve removal mostly of a few small trees on the east side and about 6 red alder trees on the west side. Enhancement of buffer will involve installation of conifer trees along the future driveway and within the historically cleared buffer in the southeastern portion of the site, which will exceed the 1: 1 ratio typically required for buffer impacts. The enhancement plan proposes to install the selected species within the historically cleared wetland and upland buffer in the south half of this property and along the future driveway. Plants to be installed in the enhanced. wetland include red osier dogwood and black twinberry in clumps with scattered western red cedar trees. The buffer will be planted with vine maple, pacific ninebark and Scouler's willow with western red cedar scattered throughout. Red osier dogwood and black twinberry will be planted in the wetland adjacent to the driveway and western red cedar will be installed in the red alder forested buffer also adjacent to the driveway. " Plant installation will take place during the first winter after the driveway is constructed, which would most likely occur during the winter of 2006-2007 since work is planned for this summer. Monitoring will be required for a period of five years to occur in years 1, 2, 3 and 5 following implementation of the enhancement plan to ensure that the plants survive and grow to emulate the former forested wetland and buffer communities. Maintenance will be necessary during the first three years to remove blackberry and other non-natives so that they do not hinder the growth and survival of the installed plants. Watering may be required each summer of the 5 year monitoring period at least one time per week to ensure survival of the installed plants. Three performance standards will be used to gauge the success of the mitigation plan and they include at least 90% survival of the installed plants and less than 15 % cover by non-natives/invasives during each year of the five year monitoring period and at least 50% cover by the native volunteer and installed plants by the end of the five year monitoring period. By the end of the five year monitoring period, the conifer trees should be at least 7 feet tall and the shrubs should be at least 4 feet tall. Contingency measures will include installation of plants if the survival rate is below the specified standard during the first two years or installation of additional plants if percent cover standards are not being met. WETLAND AND BUFFER CONDITIONS The delineated wetland crosses the entire width of the property on the east half and continues off-site to the south. The wetland extends a short distance off-site to the north where it appears to be fed by discharge from the gradual slope. There is also a seasonal upland swale conveying water from an off-site wetland to the north (Photo #2) and into the northwestern corner of the wetland (Appendix A-2). Water flows southerly through the wetland via sheet flow and enters a culvert under an existing gravel road just off-site to the south, Wetland continues in a southerly direction across the adjacent parcel. The eastern boundary of the wetland was delineated in 2002 by Olympic Wetland Resources and it was determined to be fairly accurate so it was not re-delineated. This delineation focused on identifying the western boundary of the wetland to facilitate the proposed road crossing and to verify that the proposed homesite is outside the required buffer, The wetland meets the criteria for a Category II system according to the Washington State Wetlands Rating System for Western Washington, Second Edition as require by the Jefferson County Unified Development Code. It meets the Category II criteria because it is at least 3 acres 2 in size and is composed of at least three vegetation communities. There are habitat features and relatively undeveloped buffers with a corridor to other habitat areas but it does not have salmonid usage because it lacks a formal stream channel. Buffers of 100 feet are required from Category II wetland system according to the CAO. The uplands gradually slope up from the east and west boundaries of the delineated wetland (see Photos 8-11), The upland east of the wetland was cleared about 10 years ago and has been undergoing natural re-vegetation mostly by salal and hardhack in the shrub layer and Douglas fir in tree layer (see Photos 8-11 and 14-19). There are also a few red alder, western red cedar, western hemlock, pine and madrona trees in the cleared upland. The western upland is composed mostly of a high deciduous tree canopy with a few scattered large Douglas fir trees throughout (see Photos 6-7 and 19). Since the wetland lies across the east half of the parcel, there is more upland available outside the western wetland buffer than there is on the east side with the buffer extending nearly all the way to the cul-de-sac at the parcel's southeast corner, MITIGATION STRATEGY AND SEQUENCING The Jefferson County Unified Development Code Section 18.15.350 Mitigation states: The overall goal of mitigation shall be no net loss of wetland function, value and acreage. (1) Mitigation Sequence. Mitigation includes avoiding, minimizing or compensating for adverse impacts to regulated wetlands or their buffers. When a proposed use or development activity poses potential significant adverse impacts to a regulated wetland or buffer, the preferred sequence of mitigation as defined below shall be followed unless the applicant demonstrates that an overriding public benefit would warrant an exception to this preferred sequence. (a) Avoiding the impact altogether by not taking a certain action or parts of actions on that portion of the site which contains the regulated wetland or its buffer, (b) Minimizing impacts by limiting the degree or magnitude of the action or its implementation; (c) Rectifying the impact by repairing, rehabilitating or restoring the affected environment; (d) Reducing or eliminating the impact over time by preservation and maintenance operations during the life of the action; or (e) Compensating for the impact by replacing, enhancing or providing substitute resources or environments. Avoidance This project involves crossing the northend of this small wetland system with a 12 to 15 foot wide driveway. There is no way to avoid crossing the wetland as the building site for this parcel is on the west half and the legal access is from the cul-de-sac at the southeast corner. There is no alternative to crossing the wetland with the driveway as use of existing 3 driveways has been denied by adjacent property owners and Jefferson County Public Works will not permit access from Coyle Road due to sight distance constraints. There is also not enough room on the east half to facilitate construction of a home and installation of a drainfield so it is necessary to construct the home and drainfield on the west half, which further facilitates the need for crossing the wetland. Minimization The project is minimizing impacts by crossing in a straight line at the narrowest point of the wetland, which reduces the amount of wetland and buffer impact that is necessary to facilitate access. The wetland begins about 15 feet north of the site and by crossing at the north end, the project is minimizing the impacts to the wetland system by not bisecting the wetland and essentially dividing in half. Dividing the wetland in half would have significantly more impact to the hydrologic continuity and would reduce the function of the wetland as a corridor to other habitat areas. The access route also has the least significant vegetation cover and crossing anywhere else would involve removal. of large conifer trees occupying the western wetland buffer. Compensation Rectifying and reducing or eliminating the impact does not apply to this project as the impact cannot be rectified or reduced/eliminated as it is a roadway that will serve to access the building site. Compensation is therefore the next stage in the mitigation sequencing and in this case, compensation is proposed in the form of wetland and buffer enhancement for the wetland and buffer impacts. Enhancement is proposed to improve conditions within the existing wetland and buffer at the south end and in the western buffer to screen the natural area from the driveway. . Creation is not proposed because there are no suitable areas in which to create new wetland and the costs are being kept low for this single family project. Enhancement as mitigation is required at the 6: 1 ratio of wetland enhancement to wetland impact in accordance with the Jefferson County Unified Development Code. Roughly 9,831 square feet of the on-site emergent and scrub/shrub wetland community is being enhanced to compensate for the 945 square feet of wetland fill and roughly 20,000 square feet of buffer is being enhanced to compensate for the approximately 2,400 square feet of buffer impact. The proposed enhancement has a ratio of 10: 1 for the wetland impacts and a ratio of 7.5: 1 for buffer impacts, which significantly exceeds the required mitigation ratios. PROJECT DESCRIPTION A single family home and drainfield are proposed on the west side the parcel while a pole barn is proposed on the east side. The home and barn building sites have already been cleared in preparation of construction and both lie outside the required wetland buffers. The legal access to the building site comes from the cul-de-sac at the southeast property. corner and since there is more upland available west of the wetland, the access will need to cross the wetland to reach the building site. There are no alternatives to crossing the 4 wetland as access has been denied from landowners on adjacent parcels who already have crossed the wetland with driveways. Access cannot come from Coyle Road because of sight distance issues caused by curves in the road, which has a 50 mile per hour speed limit in this location. The driveway will leave the cul-de-sac at the southeast property corner and run along the east half to the north property line. It will run along the north line and cross the wetland just as it leaves the property. The wetland is about 63 feet wide at the proposed driveway crossing and clearing will involve removal of about 5 red alder trees that range in size from about 12 inches to 36 inches dbh (see Photos 1-4). There are also 2 small cedar trees about 12 inches dbh and a small clump of cedars that will be removed as part of this project. The trees occur mostly on the west edge of the wetland and for the most part, the impacted vegetation includes slough sedge, water parsley, sword fern, and ta.ll patches of sala!. A seasonal drainage channel enters the property from the northwest and appears to provide overflow from the wetland off-site to the north (see Photo 4). A culvert is proposed to allow continuation of water flow across the driveway and this culvert will also allow drainage of water from the wetland north of the driveway so that the off-site wetland is not hydrologically impacted by the proposed driveway. The total impact area is roughly 945 square feet to include the 12 foot wide driving surface and the road slope and mitigation will take place in roughly 9,831 square feet of wetland, which exceeds the 6:1 enhancement ratio required by the Jefferson County Code. Enhancement is proposed for the impact to 2,400 square feet of buffer and will involve installation of conifer trees in the naturally re-vegetating buffer at the southeast corner and in the red alder forest buffer along the future driveway. MITIGATION PLAN OVERVIEW A driveway is proposed across the northern portion of the wetland (the wetland ends abruptly at the north property line) with a driveway to the future home and drainfield site. About 945 square feet of wetland and about 2,400 square feet of buffer will be impacted by the proposed driveway, It will involve removal of about 7 trees in the wetland area with only young trees removed in the eastern buffer and a few mature red alder trees in the western buffer. Enhancement of existing emergent and scrub/shrub wetland (see Photos 12-19) is proposed and will involve installation of conifer trees and clumps of native shrubs to supplement the shrub community that is developing after the eastern half of the site was cleared. Additional enhancement has been added along the proposed driveway route to improve vegetation cover for screening of noise and light generated on the driveway (see Photos 1, 5 and 6). Alteration of the wetland or the buffer to accommodate new wetland is not proposed and the mitigation only proposes to install additional native vegetation within the existing wetland and buffer areas. 5 Goals and Objectives of the Mitigation Plan The objective of this mitigation plan is to supplement the native vegetation that is beginning to inhabit the existing wetland and buffer areas by installing additional native species. There is plenty of downed woody debris remaining from the historic clearing activities so no additional large woody debris will be placed in the buffers, however, the trees removed from the wetland will be felled into the adjacent wetland area so that this area ha& additional woody debris. The new vegetation in the southern wetland and buffer will include species that are not currently growing in the area so there will be increased plant species diversity and they will be installed as 2 gallon individuals to provide increased plant species diversity immediately. They include mostly conifer trees that will eventually emulate the historic forested community that occupied the southern wetland and buffer prior to clearing. The conifer trees installed in the western buffer will increase the diversity of the red alder forest and will also screen the wetland and buffer from the future driveway. A few shrubs are proposed in the wetland adjacent to the driveway to also increase diversity and screen the rest of the wetland from the driveway. Shrub clumps are also proposed within the southern wetland and buffer to increase the forested understory in the enhanced areas. The eastern buffer adjacent to the future driveway is well vegetated with young trees and shrubs and does not require additional native vegetation so no planting is proposed in this location, To achieve the stated goals, the objective of the plan is to ensure that the trees and shrubs survive and grow. To determine whether the goals and objectives of this plan are being met, performance standards have been developed and will be used to monitor the mitigation site over a period of 5 years following implementation. The performance standards will include 90% survival rate among the installed plants, at least 50% cover by native vegetation in the enhanced wetland and buffer and less than 15 % cover by non- native plants including Himalayan blackberry, Scot's broom and English ivy, as well as others. The survival rate and non-native plant cover standards are expected to be met every year of the 5 year monitoring period while the 50 % cover standard is expected to be met at the end of the monitoring period, The vegetation installed along the driveway will have 100 % survival as they will be well shaded by the existing forested vegetation and installation is proposed in this area to screen noise and light from the rest of the wetland and buffer areas. Planting Plan and Specifications The plants chosen for this enhancement plan are native and common to Jefferson County. The plants as listed below and shown on the mitigation drawing (attached) shall be obtained from regional native plant nurseries and the shrubs will be planted about 6 feet apart and the trees will be 10 feet apart. Five clumps of native shrubs are proposed within the enhanced buffer and two small. clumps of native shrubs are proposed within the enhanced southern wetland. Two additional shrub clumps are proposed in the wetland adjacent to the driveway , Western red cedar trees will be installed as shown on the enhancement plan around the installed shrub clumps and around the existing vegetation. They will be thickly 6 installed in the understory of the red alder forest in the western buffer along the future driveway. The planting plan only indicates the location of the individual conifer trees, which is diagrammatic but on the ground installation will likely be as shown. No herbaceous plants are being installed because the wetland and buffer is thickly dominated by slough sedge with patches of hardhack spiraea and salal. Since the plants will be installed as potted individuals, they can be installed during the summer months although they must be watered on a regular basis. Plant installation is highly recommended during the winter months (October 15th to March 15th) when the plants are dormant so that they are in the ground at the start of spring growing season. WETLAND AND BUFFER PLANT LIST Quantity Common Name Botanical Name Size Location 24 Vine maple Acer circinatum 2 gal SE Buffer 12 Pacific ninebark Physocarpus capitatus 2 gal SE Buffer 13 Red osier dogwood Comus sericea 2 gal Wetland 24 Scouler's willow Salix scouleriana 2 gal SE Buffer 13 Black twinberry Lonicera involucrata 2 gal Wetland 42 Western red cedar Thuja plicata Min. 36" Wetland and Buffers In general, the plants will be laid out by hand at the specified spacing or as shown on the mitigation drawing and not measured out by string line. The plants will be installed by digging aone to two foot diameter hole and placing the plug from the pot into the ground once the soil around the plug is loosened. The hole will then be backfilled with the dug out soil and loosely packed down around the plug. Substitutions might be necessary for species or individuals that cannot be found at local nurseries and all plant substitutions shall be approved by the project biologist prior to installation. The project biologist will be on-site prior to installation of the plants to verify that the species, quantity, and sizes of the plants are correct and each plant is healthy and free of disease. The biologist shall also assist the landscapers with placement of plants in the areas specified on the mitigation design. An as-built design shall be prepared upon completion of the plant installation and submitted to Jefferson County Department of Community Development (DCD) and US Army Corps of Engineers (if required) showing the location of the plants and any alterations to the approved mitigation plan. Follow-up monitoring shall commence after submittal/approval of the as-built and will occur once at the end of each of the five growing seasons for following plant installation. 7 PERFORMANCE STANDARDS The performance standards have been developed to monitor the success of the installed plants with respect to the survival of individuals and percent cover provided by native plants (installed and naturally occurring) by the end of the five year monitoring period. The following performance standards have been developed for this mitigation plan: 1. Survival Rate-Every Monitoring Year · 90 % survival of planted species within the enhanced wetland and buffer areas. The main objective of this enhancement plan is to improve the plant species diversity by supplementing the existing native vegetation. It is also proposed to re-establish the forested community that dominated the wetland and eastern buffer prior to clearing activities. · 100% survival of trees and shrubs installed along the future driveway, 2. Percent Cover by Native Plants · Year One-at least 15 % cover by installed native plants · Year Two-at least 25 % cover by installed native plants · Year Three-at least 35 % cover by installed native plants · Year Five-at least 50% cover by installed native plants. 3. Plant Height-End of the Five Year Monitoring · The conifers shall be at least 7 feet tall and the shrubs shall be at least 5 feet tall by the end of the five year monitoring period. 4. Non-Native Invasive Coverage-Every Monitoring Year · Less than 15 % cover by non-native exotics, including English ivy, Himalayan blackberry, and Scot's broom MONITORING PLAN Monitoring will occur for a period of five years following installation of the plants to track the success of the project and to ensure that the performance standards and objectives are met. Monitoring will take place at the end of the summers in Years 1, 2, 3 and 5 (August or September, which is considered the end of the growing season) so that the plants have had a chance to grow through the entire growing season. The performance standards will be monitored by dividing the enhancement areas into smaller monitoring units to document the cover and survival rate within those units (unit sizes to be determined during plant installation/as built preparation). Smaller sample plots may not be feasible in the mitigation areas because of the existing native plants, Survival rate and percent cover of installed plants will be monitored in the respective monitoring units. Performance Standard HI-Survival Rate-Survival rate will be determined by counting the number of live plants within each monitoring unit and dividing by the number of plants originally installed (per design and as built), which will give a percent survival rate for each unit. 8 Performance Standard #4-Percent Cover-The percent cover standard will be monitored as if looking over each monitoring unit of the enhanced areas from above and estimating the area covered by the individual species. The percent cover within an area can total greater than 100 % because of the overlap in plant cover provided by the tree, high/low shrub and herbaceous layers. Performance Standard #3-Height of Trees and Shrubs-The height of the plants shall be monitored each year using any type of measuring device but may be most easily monitored by using a wooden carpenter's measure or yardstick to determine the yearly heights of the installed plants. Performance Standard #4-Cover by Non-Natives-The cover by non-native plants, which on this site will include English ivy, Scot's broom, and blackberry, should be kept below 15 %, which is why regular maintenance is required. The cover by these species will be determined through the same process as determining the cover of installed plants. If the percent cover by non-natives rises above 15 %, more intensive maintenance must be conducted. The monitoring phase of the project will begin upon submittal and acceptance of the as built report, which will show the location of the plants installed using photos and hand drawn maps, upon completion of plant installation. The as built drawing will then be used in .the five year follow up monitoring to track the changes in vegetative cover and . document the survival rate of the plants installed as part of the mitigation plan. Each buffer area and wetland will be monitored by dividing it into smaller units and estimating the survival rate and percent cover in each of those units. Photos will be taken of each monitoring unit to visually document the changes that occur over the five year monitoring period. Photo stations will be established at several points around the mitigation areas to include photos of all mitigation areas. Photos will be taken of the mitigation areas to provide visual documentation of the changes that occur over the five year monitoring period and included in the as built report. The as built report will be submitted to the regulatory agencies within a month of implementation. Monitoring at the end of the growing season will allow the maximum growth and survival of the individual plants to be documented. Photos will be taken of the mitigation areas from the points established during completion of the as built so that the same areas are visually documented over the entire five year monitoring period and the changes can be easily compared, The photos and data collected in the mitigation areas will be compiled into a report and submitted to the regulatory agencies to verify that the mitigation plan is developing as designed and is meeting the performance standards. The report will address whether the mitigation performance standards are being met during each monitoring year and if the. final end of monitoring period standards are going to be met. Monitoring results will determine whether or not contingency measures will be needed, 9 MAINTENANCE PLAN The mitigation areas shall be maintained at least twice during the growing season of each monitoring year to increase the survival of the plants, particularly with respect to providing water during the summer months and clearing of invasive species. Hand clearing should be done around the individual plants because it will reduce the impact to the installed plants, Hand clearing will be necessary at least two times during each growing season to ensure the weeds and grasses do not hinder the growth and development of forested communities in the enhanced wetland and buffer areas. The presence of any other native shrub or tree species (red alder, salmonberry, willows, Nootka rose, lady fern, sword fern, etc.) not specifically planted in the wetland shall be considered part of the mitigation planting plan and will not be removed, unless they begin to compete and cause widespread die-off of the installed plants. Removal of invasives may not be necessary after three years if the plants are growing well and there has been no problem with invasive plant species. Watering of the installed plants may be necessary during the drier portions of the year to ensure plant success and can be done by hand or sprinklers. The installed plants may not require regular watering after the third year if they have proven successful in terms of survival and percent cover increases. Fertilization of the installed plants, using a granular fertilizer appropriate for native species, may be necessary to initiate growth and provide nutrients that are not necessary present in the soil. Broadcast fertilizers will not be used because they could impact quality of downstream waters. CONTINGENCY PLAN Although the success of the mitigation plan is not ensured, it is likely to succeed because of the size and scope of the project. If for some reason the survival rate is less than 90% or 100%, plants that did not survive will be replaced with the same or a similar native species with the approval of the project biologist. Replacement will occur in the dormant season immediately following the growing season in which less than 90% survival was recorded. If at the end of the fifth monitoring year, the vegetation does not cover at least 50 % of the enhanced wetland and buffer areas, additional plants may need to be installed. Maintenance activities will be continued for those replaced plants to ensure their survival. The performance bond will ensure that the project will be carried out to its conclusion if the current owners fail to implement the mitigation plan or monitoring. Monitoring may be extended by another year if the contingency plan is required. PERFORMANCE BONDS Performance bonds are required by the Jefferson County Department of Community Development to ensure fulfillment of the compensation project, monitoring program and any contingency measures. The bond amounts are determined by estimating the cost of the plants and labor to install them, the cost to complete the as built letter to let the county 10 know that the mitigation plan has been implemented, and the monitoring/maintenance costs. There are two performance bonds. The first covers implementation of the mitigation plan and will be released following submittal and acceptance of the as built by the county. The second covers maintenance and monitoring and will be released upon acceptance of the' final monitoring report by the city, The amount by which the estimated costs must be multiplied will be determined by Jefferson County, Implementation of Mitigation Plan 138-gallon bareroot and/or containerized plants, labor & tax included (Based on native plant nursery price list as per planting specs) Cost for supervision by project biologist (estimated: 3 hours @$90/hr) Supervision of plant installation As-Built design and letter $1,380.00 270.00 720,00 TOTAL FOR INSTALLATION PHASE $2,370.00 Monitoring (After Plant Installation) Year One Monitoring Year Two Monitoring Year Three Monitoring Year Five Monitoring Monitoring Total $720.00 720.00 720.00 720.00 $2,880.00 Maintenance (Twice Yearly Weed Removal and weekly watering) Year One Maintenance Year Two Maintenance Year Three Maintenance Maintenance Total $400,00 400,00 400.00 $1,200.00 TOTAL FOR MONITORING/MAINTENANCE PHASE $4,080.00 11 ~ I ~ ~ ~l!i ~ ~ lti ~ ~ ~ ~ I d i ~ ~~ ~ I!f t: ~ti I'" I ~ ~il i ~ ~ ~ ~ "s ~ ~ ~~ ~ ~ :~ i ~'t: t: I"" ~ III III ~i!1:I ~~ '" ~~ i . !if ~ '" Ii; ~ .~ '" 1:1 ~~ i II >- ; t: ~ ~ I 51 ~. ~~ ~i 1:1 i~; m I 'f ~ ~ d i ~ I!! ):~~ a!l! li~ :1 ~ : ~ ~ ! ~ ~~ ~ ~ ~ ~~; ~~~ ~~ 5i ~ ~ ~ II : i ~1Il I!! ~ ~ ~i~~ l~~ ~1Il ~~ I ~ II III ~ltn ; li~hl; ;1 j! i ~ ~ ~ ~ II b _I ~. ~ i~~~ ;I:~!

Photo #1 looks south from the proposed driveway location and shows the slough sedge dominated community. Enhancement of the wetland will occur in the foreground of this photo once the driveway is constructed to screen the wetland from driveway noise and light. The trees that require removal for driveway construction will be felled into the wetland to provide additional habitat features. Photo #2 looks down into the wetland where the swale from the northwest enters the wetland. This area is dominated by water parsley and slough sedge. Photo #3 looks along the proposed driveway route from the western buffer. The stake in the foreground appears to be survey point and the flags in the middle background represent the north property line. The driveway will lie just to the right of the flags. The trees in the photo are the only ones that will actually be removed as part of the driveway construction. Photo #4 was taken from an upland hummock in the proposed driveway route and looks into the emergent dominated wetland at the point where the off-site drainage enters this system. A culvert will be placed under the road in this location to allow continuation of water flow. Photo #1 Photo #3 Photo #2 Photo #4 SHOCK WETLAND MITIGATION PHOTOS These photos show areas of buffer through which the driveway will cross. Photo #5 looks southerly into the buffer from the driveway location while Photos #6 and #7 look southwesterly and westerly, respectively, into the buffer area through which the driveway will cross. The area in Photo #6 will be enhanced with conifer trees to encourage the development of a coniferous understory and eventually overstory canopy in this location. Photo #7 actually looks along the proposed driveway route and it is clear that very little actual woody vegetation will be removed from the western buffer during driveway construction. Photo #5 Photo #6 Photo #7 SHOCK WETLAND MITIGATION PHOTOS This series of photos shows the conditions of the eastern buffer. Photo #8 looks down the slope toward the wetland along the driveway route and shows that there is little in the way of woody vegetation that will be cleared for construction of the driveway. Photo #9 looks to the left of the driveway route (south of the driveway) to show the condition of the vegetation in the remaining buffer. Photos #10 and 11 show the condition of the buffer outside the driveway crossing from a clearing outside the buffer and indicates that the remaining vegetation is very thickly dominated by many conifer trees and shrubs. Photo #8 Photo #10 Photo #9 Photo #11 SHOCK WETLAND MITIGATION PHOTOS These photos show the existing conditions of the proposed mitigation areas. Photo #12 was taken from the south property line and looks north through the emergent wetland, which is dominated by slough sedge and patches of salal remaining from the historic forested mosaic community. Photo #13 was taken from the same location as Photo #12 but looks northeasterly into the developing scrub/shrub wetland community that is dominated by hardhack spiraea. There is no enhancement proposed for the area in Photo # 12 but the area in Photo #13 will be enhanced with shrub clumps and western red cedar trees. The trees and shrubs will be planted so that they will eventually overhang the slough sedge area. Photos #14 and 15 were taken from a point about 50 feet east of Photos 12 and 13 to show the area of buffer to be enhanced. This area is mostly comprised of low growing shrubs and open grassy areas with a few scattered conifer trees. Additional native shrubs are to be installed in clumps and western red cedar trees are proposed as part of the mitigation plan. Photo #12 Photo #14 Photo #13 Photo #15 SHOCK WETLAND MITIGATION PHOTOS These photos show the enhanced buffer area from the cul-de-sac at the property's southeast corner. Photo #16 looks in a southwesterly direction across the enhanced buffer area, which from this vantage point, is mostly dominated by grasses with patches of salal and evergreen huckleberry and scattered conifer trees. Photo #17 looks in a westerly direction and shows the thicker conifer cover toward the north end of this buffer area. Photo #18 is taken from the same location as Photos 16 and 17 but looks in a more northwesterly direction across the enhanced buffer area. Photo #19 was also taken from the cul-de-sac and is included because it shows the vegetation occurring in the western buffer where the three conifer trees in the background are situated. One or more of these trees may have had to be removed if the driveway was to be constructed along the south edge. .Proposing the driveway along the north property line has resulted in avoiding removal of significant vegetation.
