PARCEL-22330500025(5-7) Chapter 6. Proposed Project & Buffer Enhancement Plan 6.1 Project Description The proposed project is for the construction of a Single Family Residence (SFR) with driveway and associated septic system. As per the Client's design presented to CLUC, the proposed SFR has a 2,500 sq.ft.footprint.A 4,514 sq. ft.driveway is being proposed (some of which is already existing), as well as a 2,079 sq. ft. septic drainfield, reserve, and valve control area designed by Arrow Septic to meet Mason County Health Department Standards (see Map in Appendix C). Buffer modifications will be necessary to allow for reasonable use of the property and will be addressed in more detail within Chapter 8. Buffer enhancement measures are addressed beginning in section 6.3 of this chapter. A brief summary of proposed buffer amendments is described below. No clearing within the wetland and/or stream is being proposed as part of this project. The total 1.06 acre parcels area is 74% encumbered by Wetland A, Stream A and their standard buffers and setbacks. Proposed development is encroaching into critical area buffers. In order to allow for reasonable use of the property similar to adjacent properties of like size,the below buffer modifications are being requested. ■ Wetland A Buffer width reduced by 33-96% in select areas. ■ Stream A Buffer width reduced by 8-95%in select areas. ■ 6,409 sq. ft. of the combined standard buffers of Wetland A and Stream A proposed to be utilized for development(see Appendix C and D). • Enhancement of 7,440 sq. ft. of buffer area that is currently cleared and lacking vegetation immediately adjacent to critical areas. This will provide a Mitigation Ratio of 1.16 acres re- planted for every 1 acre of buffer proposed for development(1.16 : 1). See Appendix E. 6.2 Project Timing Estimated start of construction of the SFR project is tentatively scheduled for the spring or summer of 2021 after the receipt of all required permits and approvals.Work will be completed in less than six months during daylight working hours normal to a residential neighborhood. Estimated start of buffer enhancement is slated to begin in the fall (potentially of 2021)following construction. All species will be planted within a five day period between October and March. Ideal planting time for trees is between early fall and early spring. Cooler and wetter weather is preferred to avoid shock for the young trees. 6.3 Buffer Enhancement Plantings Proposed plantings are intended to enhance native vegetation within the wetland, adjacent to the steam and within both standard buffers to the greatest extent possible. The outcome of the proposed plantings will be to rehabilitate an un-vegetated area and achieve increased plant diversity and density. Work will include planting approximately 149 trees and 521 shrubs/herbs within the designated buffer enhancement area. If the species listed within this report are not available, substitutions must be similar in nature providing the same habitat benefit as those proposed.Alternative species require pre-approval by a qualified specialist and/or regulatory staff at Mason County. 141Page r All plant materials used for the enhancement actions will be nursery grown stock from a reputable local source. Only native species are to be used; no hybrids or cultivars will be allowed. Plant material provided will be typical of their species or variety; if not, they will exhibit normal densely developed branches and vigorous,fibrous root systems. Plants will be sound, healthy,free from defects and all forms of disease and infestation. Trees will be spaced a minimum of 10-foot on center and other species will be four(4)or five (5)feet on center as a minimum standard. Placement will be sporadic and determined by a qualified biologist at the time of enhancement. Plant quantities listed in this report are estimates derived after careful review of conditions within the proposed buffer enhancement area.These quantities represent the maximum number of plants that will fit within the area based solely on minimum plant spacing requirements and without considering any existing vegetation that will be preserved. Conceptual plant locations within a 100 square foot area have been included on the map in Appendix E. Deviation from conceptual location is reasonable for implementation of the planting plan in the field.All alterations in location, species, and spacing shall be recorded by the installation team and qualified specialist for compliance reporting purposes and in the preparation of an as-built plan. To ensure optimal survival, and that the plants do not dry out after installation,temporary irrigation measures may be necessary. Table 9.

All prices subject to change. These figures are estimates and plants may be obtained from a wide variety of vendors across the region. See Appendix W for a list of native plant sources from the Washington Native Plant Society. 6.4 Buffer Enhancement Sequencing A. CLUC(or other qualified contractor)will mark where each plant should be placed in the field. Prior to planting, CLUC (or other qualified contractor) will monitor for invasive and nonnative species within the enhancement area and oversee any surface preparation for planting. B. A qualified plant installation specialist will source, procure, and plant the trees (under the supervision of CLUC if so requested by the client. No tilling of the ground will occur. Holes for each plant will be dug individually and will be two to three times the width of the container.All excavation work, though minor will only be performed during dry weather. All species will be planted within a five day period between October and March.All plantings should occur during the winter dormancy period. All installed vegetation may be marked with colored flagging when necessary to facilitate monitoring inspections. C. CLUC (or other qualified contractor) will complete an As-Built Installation Plan for submission to the county within one(1) month of planting. 151Page PARCEL D. Client will monitor growth and adhere to best management practices outlined within this report. E. CLUC(or other qualified contractor)will perform an annual site visit in the late summer of monitoring years 1, 2, 3, and 4 and will provide a Monitoring Report to the county no later than October 1 of that year.The Monitoring Report will suggest needed corrections and adjustments to the plan based on survival of planted species determined in each report. F. CLUC will provide final site inspection and Monitoring Report to Mason County by October 1 of year 5. 6.5 Buffer Enhancement Performance Standards The following performance standards are targeted for the proposed enhancement identified within this report.These performance standards are necessary for the evaluation of success achieved in implementing the proposed enhancement.Failure to meet these standards by the end of the monitoring period will require an additional year of monitoring. Table 12. Plant Survival Benchmarks YEAR 1 YEAR 2 YEAR 3 YEAR 4 YEAR 5 PLANT SURVIVAL 100 percent 100 percent 80 percent 80 percent 80 percent PERCENT COVER- 20 percent 28 percent 35 percent TREES/SHRUBS PERCENT COVER- 45 percent 53 percent 60 percent HERBACEOUS Individual plants that die in the first or second year must be replaced with native species taken from the approved plant list included in this document. 6.5.1 Contingency Individual plants that die in the first or second year must be replaced (at a 1:1 ratio) with native species suggested by a qualified biologist and approved by Mason County.After the second year, if mortality of the installed vegetation exceeds 20 percent, all dead materials will be replaced at a 1:1 ratio. If mortality is related to an inappropriate species for the site conditions,adjustments to the Plant Schedule may be made to replant with a species more likely to survive. Other actions include changes to or adoption of a watering schedule, or integrated pest management(excluding pesticide use). 6.5.2 Invasive Species Invasive vegetation will be removed from the restoration area and continue to be removed as they are established.Washington State-listed or county-listed noxious weeds observed in any area of the mitigation site must be eradicated with no part of the plant remaining. Non-native species will include less than 10% cover in the mitigation area during the monitoring period. Due to the close proximity of the enhancement area to the Wetland A and Stream A, use of pesticides for noxious weed control should be avoided. Continued manual removal is the appropriate course of action for this area. 6.6 Buffer Enhancement Monitoring CLUC, or other persons qualified to evaluate the buffer enhancement, shall implement the Vegetation Management Plan. Upon installation of vegetation, CLUC or another qualified person(s)will create an as- 161Page built plan to submit to Mason County within 30 days of completing the work. Following the installation, a monitoring report shall be provided via email to the Mason County Planning Department no later than October 1 of monitoring years 1-4. Enhancement work should be reviewed by CLUC or another a qualified person(s)to ensure that the enhancement area is healthy and meeting the Performance Standards listed in this report. It is suggested that monitoring occur in late summer or early spring as these are the ideal time of year to assess the health of the plantings. The as-built plan should establish at least five (5) photo points on-site that portray the planting area from each side of the property.These points should be maintained and used to capture the vegetation's growth over the five(5)year monitoring period for inclusion in the yearly monitoring report. The as-built plan may include a brief letter that consists of a summary of actions and associated maps and pictures, and other information deemed necessary by Mason County. The annual monitoring reports should include the following minimum information: 1. Observations of species survival; 2. The use of the site by wildlife species; 3. Any disturbance caused by the development and its effect on protected zones and associated aquatic habitat; 4.Any occurrence of exotic species and its removal within the restoration zones; 5. Replacement of vegetation since planting. 6. Any corrective measures that may be deemed necessary to provide desired conditions. 7. Any maintenance actions taken. Five (5) years post planting, a review of the vegetation within the buffer enhancement area shall be completed and a final Monitoring Report provided to Mason County. This document should be a determination of success regarding vegetation coverage, health, and sustainability. 6.7 Buffer Enhancement Maintenance Maintenance of the enhancement area should consist of all actions necessary to promote survival of the planted native vegetation.Actions may include removal of dead vegetation, irrigation during the dry season, mulching,fertilizing and similar measures. Broadcast fertilization, however,will not be used. 6.8 Buffer Enhancement Surety Bond An estimated cost breakdown for plants, biologist, and monitoring services is provided in the table on the following page to assist in calculating the bond amount should one be required. For the purposes of this report, no amount is listed for plant installation labor and other associated supplies. A fair market quote from a qualified plant installer will be necessary to complete any bond amount calculations. CLUC does not provide plant installation services but can obtain a quote from a third party contractor and coordinate service for an additional fee if requested. 171Pa e DELINEATION"PUP-CRATER LAND USE CONSULTING,DECENIBE Z02Q Table 9.
