":<; \ ~--, SELECTEtl COMPENSATORY MITIGATION APPROACH Site planning for the Evendell Resi(Jenti~-1 Community has focused on the mandated. hierarchy of wetland impac_t ·reduction: 1) avoidance, 2) ;nlnimization, and 3) compensation. These avoidance and minimization strategies included a site design to ~void all adverse impacts to onsite wetland systems, except those minor impacts required by King County to create SE 136 111 Street. The total amount of King County jurisdictional wetland area to be modified by the development of SE 136 111 Street equals 225 square feet (0.005 acres). As compensation for this unavoidable impact 550 square feet (0.012 ac_res) of degraded wetland area would be restored and enhanced through the planting of native trees and·shrubs. In addition, Tract P would be added to the overall protective buffer.established by this mitig.ation program. This compensatory action has been reviewed and approved by King County environmental staff. • Mitigation Benefits The restoration and enhancement of the northern tip of the existing Class 2 Wetland is designed to accompany site development. The primary benefits associated with the proposed restoration and enhancement includes the creation of a viable plant community composed of native shrubs and trees. The selected plant species would increase plant community and wildlife habitat diversity and complexity within the wetland area. The restored and enhanced wetland area would provide increased screening protections for the wetland area adjacent with the new public roadway. In addition, the addition of Tract P to the overall established buffer would provide increased protection for the onsite wetland and additional retained wildlife habitats. • Selected Mitigation Area The selected mitigation area is located at the northern tip of the onsite Class 2 Wetland. The plant community within the selected area is presently limited as a result of prior land use actions. DESCRIPTION OF THE ~ITIGATION PROGRAM 1. As _compensation for the unavoidable filling of 225 square feet (0.005 acres) of identified King County Class 2 Wetland the ar_ea directly south of the impacted wetland area shall be restored and enhanced through the planting of a variety of native trees and shrubs. The area to be restored shall be a minimum of 550 square feet (0.012 acres) in size. The selected species shall increase plant community and wildlife habitats diversity and complexity. ' Ill 2. As compensation for the reduced buffer caused by the development of SE 136-Street along the northern edge of the identified King County Class 2 Wetland the existing forested area in the northeastern comer of the project site (Tract P) shall be added to the overall buffer area. 3. All onsite activities shall be monitored by the project biologist. Following the completion of onsite planting activities a "record-drawing" (i.e. "as-built") plan shall be prepared and submitted to King County. A five-year monitoring program shall be undertaken to assure the success of the compensatory mitigation program. 4. Temporary and long-term erosion co_ntrol measures shall be implemented. These measures include silt fencing during site preparation and wetland planting, and seeding of all exposed soil areas. 5. The retained wetland and associated buffer shall be identified as separate tract. T~e outer boundary of this tract shall be ·fenced and posted with _standard King County buffer boundary signs at a minimum interval of 50 feet. GOAL AND OBJECTIVE OF THE MITIGATION PROGRAM The GOAL of the compensatory mitigation program ·is to fullylhcompensate for the u~avoidable adverse impact to Wetland A caused by the required development of SE _136 Street. . The restoration and enhancement of a portion of the onsite wetland shall provide full compensation for unavoidable wetla~d impacts. Upon the completlon of this mitigation plan there shall be no net loss of wetland funct1_ons or values. To achieve the defined GOAL, the-following OBJECTIVES and PERFORMANCE CRITERIA have are defined: Objective A. The restored and enhanced compensatory mitigation area shall_ be a minimum of 550 square feet (0.012 acres) in total size. The restor~d and enhance~ .compensatory m_1t1g~t1_o_n wetla~d ~rea shall exhibit a scrub/shrub and sapling tree vegetation classes within five years following 1rnt1al planting. Performance Criterion #A 1: As defined by plant count 100% of the trees and ~hrubs initially installed within_ _the compensatory wetland area shall exhibit survival through the end of the first growing season following -· .--planting. Performance Criterion #A2: As defined by plant count 80% of the trees and shrubs initially installed within · the compensatory wetland area shall exhibit survival through the end of the fifth growing season following plantinQ. Performance Criterion #A3: As defined by aerial coverage, invasive non-native species shall not exceed 15% at the end of the fifth growing season following planting within the restored and enhanced .. compensatory wetland area. IMPLEMENTATION INSPECTION Essential to the success of the mitigation program is the accurate inspection of onsite activities immediately . prior to and during the initial wetland restoration and enhancement phase. These activities include pre- implementation site inspection, onsite inspection and technical direction during wetland planting act1v1t1es, and _ post-planting site inspection and evaluation-. · The pre-implementation site inspection allows the project team and the project biologist to evaluate and, if necessary, undertaken minor adjustments in the onsite implementation steps. These steps include .analysis of project site elevation features, project sequencing and timing, final grade analysis, unforeseen required minor modifications to the original establishment plan, and the establishment of environmental protections (silt fences, etc.) required during implementation. Onsite technical inspection during implemen!ation and pl~nting activities shall be implemented by the project biologist. The project biologist shall perform 1mplementat1on oversight and address minor unforeseen implementation difficulties to assure that the intent of the compensatory mitigation program is met. The project biologist shall also be responsible for ensuring that the species and sizes of native plants selected and noted within the final planting plan are utilized during implementation. If selected native species become unavailable, the project biologist shall consult with King County for substitute plant species to assure that the intent of the compensatory mitigation program is met. Post-implementation site inspection/ evaluation shall include the preparation of a "record-drawings' which shall be submitted to King County. CONTINGENCY PLAN As a contingency, should the proposed compensatory mitigation program fail to meet the performance criteria, the project proponent shall undertake required remedial actions. Where plant survival is the failing component, the project proponent shall replant and ensure the success of this second planting which would be held to the same -standard of success as nieasured by threshold criteria and monitoring processes: Where non-native, invasive vegetation exceeds 15% aerial coverage the project proponent s~all undertake removal actions. Such removal actions shall be completed using hand tools or pulling the plants by hand to remove the invasive vegetation without disrupting the soil profile. All cut or pulled vegetation shall be removed from the mitigation area and disposed in an approved location. Herbicides shall only be used following approval by King County. All herbicide application shall be completed by a licensed professional. Should additional remedial actions be required, the project proponent shall meet with the King County to establish and define actions to be taken to meet the desired goal of this mitigation program. TEMPORARY IRRIGATION The project proponent shall ensure that a minimum of one (_1) inch of water is supplied each week to the compensatory mitigation area between June 1 and October 15 for a least the first two years following initial planting. The calculated amount of required water shall include both natural rainfall and temporary irrigation . The need for additional years of irrigation shall be determined based on sit_e conditions and overall plant survival. The amount of water supplied to the compensatory mitigation area shall be increased if onsite monitoring defines such a need. PLANTING NOTES With the exception of the identified grass seed mixtures, all plant materials utilized within the restore and enhanced wetland shall be native to the Puget Sound Region. The onsite biologist shall inspect plant materials to assure the appropriate plant sc~edule and plant characteristics are met. The project proponent shall ,. a(!ljiviiielll••lil<leop,ogje~ponent shall replace all dead and unhealthy plants with planls -of the same specifications. ·I r I, IMPLEMENTATION SCHEDUL!: PROJECT TASK Onsite re-im lementation ro·ect meetin · Placement of protective fencihg; final marking, and identification of work area.

PROJECT MONITORING TASK SCHEDULE Com ieted b Au . 15 2004 Completed by Aug. 30, 2004 Following the successful completion of the proposed wetland planting a five-year monitoring and evaluation program shall be undertaken. The purpose of this program is to er.sure the. success of the selected mitigation as measured by an established set of performance criteria. This monitoring may also provide valuable information on the effectiveness of mitigation procedures. STANDARDS OF SUCCESS • Vegetation Sampling Methodology and Monitoring Schedule The monitoring program shall count each plant initially installed within the restored and enhanced wetland area. The evaluation of the success of the compensatory mitigation program shall be based on the selected survival rate for trees and shrubs. These defined performance criteria shall be appiied at the times of yearly monitoring. The percent surviyai rate shall be based on combined counts of existing, volunteer plants, and planted species during vegetation monitoring. Sample location shall be shown on the "record drawings" (i.e. 'as-built") plan, and shall correspond to identified photopoints. Trees and shrubs shall be visually evaluated fo determine the rate of survivorship, health, and vigor of each plant. The categories to be used shall include live, stressed, tip dieback, basal sprouts, not found, apparently dead, and dead. • Vegetation Monitoring 1. As_ a part of each monitoring period the project biologist shall count the number of live plants initially planted w_ithin the representative sample plots. Plants shall be identified to species and observations of general plant condition (I.e., plant health, amount of new growth) shall be recorded for each plant. 2. Within the restored and enhanced wetland the project biologist shall count the number of undesirable invasive plants and estimate the aerial coverage (as if the observer were looking straight down from above) of these invasive plants. Undesirable plants include blackberries, Scot's broom, tansy ragwort, reed canarygrass, and plants listed in the Washington State Noxiou·s Weed List. 3. Within the restored and enhanced wetland the project biologist shall count the number of desirable "volunteer" plants and estimate the aerial coverage of these plants. · 4. . The project bi?logist shall take photographs that show the entire compensatory mitigation area. . During the five-year morntonng penod photos shall be taken in the same.direction and at the same location to provide a series of photos._ These photos shall show plant growth, plant species, and plant coverage. 5. . Upon the completion of each annual mon_itoring period the project biologist shall prepare a report · defining methods, observations, and results along with the date the observations were completed. Each report shall be provided to the County. 6. The monitoring schedule is defined as: A. Twic~ a year for two years following the completion of initial onsite planting. For each monitoring year, onsite monitoring would be completed once early in the growing season (late March to mid-April) and once again near the end of the growing season (mid-September). For each onsite monitoring activity an annual r_ep~rt would be prepared and provided to King County within _three weeks after the completion of the fall rnorntonng. ·. - 8. Once a year for years three,_four, and five following the completion of initial onslte planting. For each morntonng year, ons1te morntonng would be completed once near the end of the growing season (rriid- S~p_tember)....Eor each onsite monitoring activity a report would be prepared and provided to King County within three weeks after the completion of onsite monitoring.

VEGETATION MAINTENANCE PLAN \ \ \, ' ' ' Maintenance of the restored and enhanced wetland 1may be re~uired to assure the long-term health and welfare of the Welland's environniental functions. Stich mainten'ance would be identified during the monitoring period and undertaken only following discussion and .i:oordination with King County. The overall objective is to establish undisturbed plant communities that do not r~,quire maintenance. Activities may include, but are not limited to, the removal of invasive non-native vegetatiqn and the irrigation of selected areas. Established , maintenance activities include the removal of any tras~ within the wetland or buffer. · \( REMOVAL OF INVASIVE NON-NATIVE VEGETATIO~ \ As a contingency, should the removal of invasive non-native vegetation\ecome necessary within the restored ., and enhanced wetland area, the project proponent shall contact King County to establish and define specific '. \ actions _to be taken: .. Resultant contingency plan activities shall be impleni~nted when the ongoing vegetation J morntonng program indicates that plants listed in the Washington State Noxious Weed List, blackberries, reed ;' canarygras~, or Scot's broom ·a,re becoming dominant in the community or e~ceed 15% of the aerial coverage ' of the planting areas. , I ' ., SEEDING FOR EXPOSED AREAS Seeding for all exposed-surfaces within the mitigation area shall be completed within two weeks following the exposure of the soil.
