Olympia WA INTRODUCTION This study reports the results of a wetlands buffer impact analysis and restoration plan for a property located at North 30 Deer Court, Lot#52 Division#14, Lake Cushman, Washington. The property is recorded at the Assessor's Office as Parcel #422055000052 and is owned by Mr. Dale Janicek. The study was conducted by Celina Abercrombie, Restoration Specialist from Agua Tierra Land and Water Services, Inc. This report has been prepared at the request of Mr. Janicek. An un-permitted small cabin was constructed on the subject property. A copy of the site plan is included in Appendix A for reference. Un-permitted vegetation clearing has occurred on-site within the regulated wetland buffer and standard building setback. The objectives of this study include the following: i (1) Report the results of an impact analysis for the recent un-permitted activities r that have occurred on-site; and (2) Develop a Restoration Plan to meet Mason County Critical Area Enforcement ` requirements for permitting (Chapter 17.01.2001). Location The property is located at North 30 Deer Court, Lot#52 Division#14, Lake Cushman, Mason County, Washington. The study area is situated in a portion of Section 5, T22N, R4W(W.M.). Vicinity and assessor maps are included in Appendix A. 1 Site Description The property is polygon shaped and less than an acre in size (see Assessors map in Appendix A). A small cabin was constructed on an existing partially cleared and graded (leveled) area. An excavated access road extends south from Deer Court to the cabin, parking area, and septic. i Immediately south, east and west of the leveled area is forested with dominant plant species including Western redcedar(Thuja plicata), red alder(Alnus rubra), bracken fern (Pteridium aquilinum), salal (Gaultheria shallon), and trailing blackberry(Rubus r ursinus). i A Category II depressional outflow wetland system was identified on-site within the r southeastern corner of the property and extends.off-site to the south(see Wetland Delineation Map in Appendix A). Lake Standstill is situated to the southwest of the property and is connected to Wetland A through a drainage that enters from the west. Lake Cushman is adjacent to Lake Standstill to the west. Topography on site slopes from Deer Court towards Wetland A in the southern portion of the property. Surrounding land use in the project vicinity is rural/recreational residential to the north, east and west with wetland open space to the south. - 2 - e JANICEK IMPACT ANALYSIS AND RESTORATION PLAN Prepared by: Agua Tierra Land and Water Services, Inc. - Olympia WA l Soils for the study area are included in the soils mapping performed in the Soil Survey of Mason County Area, Washington(USDA, 1960). The mapping shows the property to include mapped soil series: McMurray peat, 0 to 2% slopes (hydric) and Hoodsport gravelly sandy loam, 5 to 15% slopes (non-hydric). Site observations made during site investigation generally agreed with the soil survey mapping. Representative site photos are included for reference in Appendix B. IMPACT ANALYSIS An unpermitted cabin was constructed on an existing partially cleared and graded (leveled) area of the subject property. The seasonal cabin is approximately 196 square feet in size (14 feet by 14 feet)and situated within the regulated wetland vegetated area (buffer) and standard building setback. The impacted area is identified on the Restoration Plan map included in Appendix A. Vegetation Impacts Approximately 196 square feet of native vegetation was removed from the regulated wetland buffer and building setback. Site conditions prior to vegetation clearing within the regulated buffer area was a densely vegetated area dominated by Western redcedar (Thuja plicata), red alder(Alnus rubra), bracken fern (Pteridium aquilinum), salal (Gaultheria shallon), and trailing blackberry(Rubus ursinus). r Soil Impacts ` Approximately 196 square feet of native soils were disturbed during removal of native vegetation. ` Reasonable Use and Avoidance Per Mason County,the cabin structure can remain in its current location provided that the client applies for a Mason Environmental Permit(MEP), MEP associated fees are paid, a restoration plan and bond are submitted to the County, and seasonal monitoring of the site is provided (letter from Tammi Clark dated 8/9/04). After-the-fact permitting and associated fees have been paid and the county has approved the structure to remain in its current location. The Restoration Plan to follow identifies measures to compensate for permanent impacts to the wetland vegetated area(buffer) and standard building setback totaling 196 square feet. - 3 - JANICEK IMPACT ANALYSIS AND RESTORATION PLAN Prepared by: Agua Tierra Land and Water Services,Inc. e Olvmnia WA t RESTORATION PLAN Goals and Performance Standards The overall goal of this restoration plan is to restore disturbed forested area by achieving specific goals and performance standards listed in Table 1 below. It is recommended that a minimum of 196 square feet of disturbed buffer be restored through native plantings.

Substitute plants subject to approval by Mason County Department of Community Development. Location of Restoration Areas The location for proposed restoration activities is identified as Restoration Area A on the Restoration Plan map in Appendix A. Planting Plan It is recommended that Restoration Area A (approximately 196 square feet) be planted with native vegetation to restore the regulated buffer area. Recommended plant densities are as follows: Trees: 10 feet on center Shrubs: 5 feet on center Groundcover: 3 foot on center The overall transplant densities have been selected to eventually provide a moderately dense, structurally diverse plant community in the buffer area. Natural volunteer vegetation of the species listed for planting shall be counted towards the desired densities of restoration plants. Volunteer vegetation not listed above may substitute for the specified plants with the approval of the reviewing Mason County staff, provided the - 4 - t JANICEK IMPACT ANALYSIS AND RESTORATION PLAN Prepared by:Agua Tierra Land and Water Services, Inc. t Olympia WA plants are not invasive, undesirable species such as reed canary grass, non-native blackberries, or English ivy. ` Native plant species, densities, size and quantities that may be used within the restoration planting areas are listed below in Table 2. b TABLE 2 Restoration Planting Area Species, Density, Size, and Quantity (Restoration Area A = 196 square feet) Planting Sfirata Species Density Size Qty Area (feet on center A Tree Western redcedar(Thuja 10 1 gallon or 1 Licata) bare root A Tree red alder(Alnus rubra) 10 1 gallon or 1 bare root A Shrub vine maple (Ater circinatum) 5 1 gallon or 8 bare root A Groundcover salal (Gaultheria shallon) 5 1 gallon 22 Plant material can be obtained from one or more of the following licensed regional nurseries: Colvos Creek Nursery,Vashon Island, WA (206) 749-9508 Sound Native Plants, Olympia, WA (360) 352-4122 Black Lake Organic Nursery, Olympia, WA(360) 786-0537 Watershed Garden Works, Longview, WA (360) 423-6456 Woodbrook Nursery, Gig Harbor, WA (253)265-6271 McComb Road Nursery, Sequim, WA (360) 681-2827 Planting Procedure Planting pits for transplants shall be 1.5 times the depth and twice the diameter of the transplant root balls. Remove the plant from the container and scarify the sides of the root ball. Place approximately 1-2 gallons (depending on size of root wad) of nutrient rich topsoil in planting hole. Place plant in the planting pit. Backfill the planting hole with topsoil to finish grade. Water the plant well during and after planting. Example drawings are provided in Appendix C. Overall, plant species can be placed randomly throughout the identified revegetation area at the densities previously discussed. It is recommended that the shrub species be planted in clusters (example: 10 salal all in same area, each plant spaced 5 foot on center). Maintenance and Exotic Plant Control Maintenance shall consist of irrigation, replacement of dead/dying or undesirable transplants with appropriate vegetation, and removal of native noxious and invasive weeds. No post-planting applications of fertilizer are anticipated. Deep irrigation of - 5 - r JANICEK IMPACT ANALYSIS AND RESTORATION PLAN Prepared by: Agua Tierra Land and Water Services,Inc. Olympia, WA native plantings is recommended no less than twice monthly during May 15th—October 15th of the first two years. Monitoring Under Mason County regulations (Chapter 17.01.200 I.) monitoring of the site will be required to periodically evaluate the success of the restoration and provide amendments to the plan, which may become necessary to achieve its purpose. Plants should be monitored for a minimum of 80% survival and visible growth of all transplants or natural ' volunteer substitutes for a period of 3 years. Any natural volunteer substitute plants are subject to approval by Mason County Department of Community Development. } The owner shall provide for seasonal monitoring of the site by a qualified biologist or other qualified professional, for a period of three years after completion. The applicant shall submit an annual report to the County that meets the requirements of Chapter 17.01.200 I.2. Restoration Schedule Recommended timing and sequence of restoration and required monitoring activities are provided below in Table 3. TABLE 3 Schedule for Restoration 1. Install native plants Spring 2005 (February—March) ` 2. is year monitoring report(call A ua Tierra biologist) October 2005 3. 2° year monitoring report(call A ua Tierra biologist) October 2006 4. 3rd year monitoring report(call Aguat Tierra biologist) October 2007 It is recommended that the vegetation area replanting occur during winter dormancy. Site conditions permitting,the optimum time for planting most native woody plant material appears to be the later part of winter and early spring (February-March). Plants installed early in the dormant season tend to be subject to winter kill and die back. Conversely, plants installed during the late spring and early summer have been observed to be much less drought tolerant during the dry summer period. Contingency Procedures Contingency actions could include, but are not limited to, replacement of plants which have not achieved the standard survival or coverage goals according to the proposed planting density; substitution of specified plant species; additional irrigation requirements; repair of damage due to erosion or other topographical changes to the site; and amendments to the restoration plan during monitoring as necessary to achieve its purpose. - 6 - JANICEK IMPACT ANALYSIS AND RESTORATION PLAN Prepared by: Agua Tierra Land and Water Services, Inc.
