All planting and site preparation operations shall be conducted accordingtoAmerican Nurseryman's Association Guidelines. 2. Installation will be performed by a Contractor with experience in native plant restoration, particularly wetland creation. 3. The limits of work within the mitigation area shall be clearly flagged in the field and observed throughout the construction phase. No disturbance will be allowed beyond the mitigation area. 4. Remove all weedy species such as reedcanary grass, Scot's broom, and blackberry as directed by the Wetland Ecologist. 5. Prior to plant installation soil samples will be taken to determine the existing soil's suitability as a planting medium. Recommendations will be made regarding the need for soil amendments and imported topsoil based on test results. The Contractor must obtain these recommendations from the Wetland Ecologist before the installation of plant material begins. 6. All plant materials shall be native to the Northwest and preferably to the Puget Sound region. Plant material shall be from native stock, no cultivars or horticultural varieties will be allowed. Plant material shall be from nursery grown stock, unless otherwise approved, by the Wetland Ecologist. 7. Contractor to verify all quantities on planting plan. In areas of conflict, the quantities shown on the drawings shall supersede the plant schedule. 8. All plant material scheduled for installation will be identified in the plant schedule for this project. Proposals for substitutions require the approval of the Wetland Ecologist. 9. All plant material shall be inspected by the Wetland Ecologist prior to installation to verify conformance to the plant schedule and plant characteristics. The Welland Ecologist reserves the right to require replacement or substitution of unsuitable plant material. 10. Plants shall be installed per the planting plan following accepted procedures as outlined in the planting notes, specification document, and current industry standards. 1 1. Plants shall be placed as shown on the drawing in clustered groupings or as directed by the Wetland Ecologist. 12. The requirements of all nursery grown plant material are identified in the plant schedule and shall be bare root, containerized, or balled and burlapped. Only sound, healthy, vigorous plants, free of defects, diseases, and all forms of infestations will be accepted. The Wetland Ecologist can provide a list of nurseries where native plant material is available. 13. To assure greater survival of newly planted material an autumn planing (Oct. -Dec.) is recommended. Implementation at this time will also minimize the impacts of erosion and sedimentation resulting from construction operations. Spring planting (March - April) will require an irrigation program throughout the summer season. The irrigation program shall be developed by the Contractor and approved by the Welland Ecologist. 14. No planting activities shall commence until completion of site preparation and earth work. Under optimal conditions it is recommended that trees be installed during the fall planting season, and shrub material during the spring planting season. 15. The Contractor shall protect from damage all plant material scheduled to remain within the limits of the project boundaries. 16. Dig, pack, transport, and handle all plants with care to ensure protection from injury. Store plants in the manner necessary to accommodate their horticultural requirements.

Do not allow wetland plants to dry out or sit in the sun prior to or during installation. Immediately saturate the wetland planting area after planting to avoid capillary stress. 18. Plant installation will commence when the finish grading in the planting area has been completed 19. Plant material delivered and accepted shall be planted immediately. Plants that can not be planted within one (1) clay after arrival shall be "heeled -in" in accordance with accepted horticultural practice. When authorized by the Wedaad Ecologist, plants may be temporarily stored at the sole responsibility of the Contractor. Plants in storage shall be protected at all times from extreme weather conditions. All plants that must be stored longer that one (1) month shall be planted in nursery rows and maintained by the Contractor at no additional cost to the Owner. Plants temporarily stored shall be subject to inspection and approval by the Welland Ecologist prior to planting. 20. Do not remove container grown stock from containers until the planting time. Containerized plants shall be removed from their containers in such a manner to prevent disturbances to the root system. Under no circumstances shall the plant be removed from the container by pulling the main stem. Plants removed from their containers shall be planted without delay. 21. Excavate circular planting pits with vertical sides and install plants as shown in the planting details. Backfill excavated pits with native soil and amendments as required in the specifications and planting details. 22. Planting shall not he done during freezing weather or when conditions are unfavorable to work. 23. Plants shall be protected at all times to prevent the roots from drying out during the planting operation. 24. Install a granular type fertilizer into the planting pits of all material. The composition and application rate must be approved by the Wetland Ecologist prior to installation. Fertilizer will be allowed in planting pits only. 25. A 3 inch layer of mulch shall be applied to the circle of bare earth around individual upland plantings to inhibit competition from herbaceous plants.

POST -EMERGENT HERBICIDES ARE SYSTEMIC HERBICIDES THAT KILL ALL PLANTS AFTER THEY HAVE SPROUTED. THE SINGLE MOST USEFUL POST -EMERGENT HERBICIDE RECOMMENDED IS GLYPHOSATE KNOWN BY THE BRAND NAMES ROUNDUP, ROUNDUP RT, AND RODEO). RODEO HAS A SURFACTANT OR ADJUVANT THAT IS NOT ALLOWED WITHIN 100 FEET OF A WATER SOURCE. THIS HERBCIDE HAS A SHORT HALF-LIFE AND IS EFFECTIVE FOR ONLY A SHORT PERIOD OF TILE. FOR THIS REASON, IT IS ONE OF THE SAFEST AND IS RECOMMENDED FOR USE NEAR WETLAND AREAS. GLYPHOSATE TRANSLOCATES TO THE ROOTS FROM THE LEAVES OR STEMS, BUT IT WILL NOT MOVE INTO THE SOIL. TO CONTROL JAPANESE KNOTWEED, THE USE OF 2,4 DAMINE IS RECOMMENDED. THIS IS A MUCH MORE TOXIC HERBICIDE, WHICH IS NOT ALLOWED WITHIN 100 FEET OF STREAMS OR WETLANDS. CARE SHOULD BE TAKEN WHEN USING HERBICIDES, AND PACKAGING INSTRUCTIONS MUST BE FOLLOWED WHEN THEY ARE APPLIED. TYPICALLY, HERBICIDE USE WITHIN 100 FEET OF WETLANDS IS NOT ALLOWED EXCEPT IN SPECIFIC SITUATIONS. ON THIS SITE, HERBICIDE TREATMENT MAY BE USED IN AREAS LESS THAN 100 FEET FROM THE WETLAND IF THE HERBICIDE USE IS ROUNDUP (GLYPHOSATE WITHOUT A SURFACTANT) APPLIED BY THE WIPER METHOD OR LOW VOLUME NOZZLE ON A KNAPSACK SPRAYER. WIPING GLYPHOSATE IS MOST EFFECTIVE AFTER FLOWERING, BUT BEFORE SEED MATURES. HERBICIDE TREATMENT USED ON THE WEEDS MORE THAN 100 FEET FROM THE WETLAND EDGE MAY INCLUDE RODEO (GLYPHOSATE WITH A SURFACTANT, USUALLY A 2 PERCENT SOLUTION OF MIXTURE - B). SPRING AND EARLY SUMMER SPRAYING WILL CUT BACK ON GROWTH, BUT OFTEN DOES NOT KILL THE PUN. EACH SPROUT SHOULD BE EITHER SPRAYED OR TOUCHED WITH THE WIPER APPLICATOR, THIS INCLUDES EVEN THE SMALL SPROUTS. HERBICIDES SHOULD BE APPLIED AT EXACTLY THE RATE AND TIME IN THE PACKAGING INSTRUCTIONS. THE USUAL RECOMMENDED INSTRUCTIONS LIST GLYPHOSATE APPLICATION AT A RATE 0 5 LITERS / HA. = 1.85 QUARTS / ACRE OF 0.026 PERCENT SOLUTION. THE CONCENTRATION AND APPLICATION RATE LISTED ON THE PACKAGE SHOULD BE USED IF IT DIFFERS FROM THIS FORMULA. SPRAY APPLICATION SHOULD UTILIZE A SMALL AREA NOZZLE TO MINIMIZE DROPLETS STRAYING FROM THE PRESCRIBED AREA. SPRAYING SHOULD BE DONE WITH THE WETLAND AT YOUR BACK, AWAY FROM THE WATER SOURCE. WIPER APPLICATION ENTAILS USING A WAND WITH A SPONGE -TYPE TIP AND APPLYING THE GLYPHOSATE DIRECTLY TO THE PLAN TO BE ERADICATED. ALL APPLICATION RATES SHOULD BE VERIFIED BEFORE MIXING CHEMICALS. IRREGULAR TERRAIN SHOULD ALSO BE CONSIDERED WHEN APPLYING CHEMICALS. THE IDEAL TIME FOR SPRAYING IS JULY AND AUGUST. SPRING AND EARLY SUMMER SPRAYING WILL CUT BACK ON GROWTH, BUT OFTEN DOES NOT KILL THE PLANT. THIS SCHEDULE SHOULD BE CONTINUED AS REQUIRED THROUGHOUT THE 10-YEAR MONITORING PROGRAM FOR THE ASSOCIATED MITIGATED AREA. THE COE WILL DETERMINE IF CONTINUE SPRING IS NECESSARY AT YEAR FIVE. Q MDMICIP O POST -CONSTRUCTION MONITORING SHALL BE PERFORMED BY COOKE SCIENTFIC SERVICES, INC. THE GOAL OF THE MONITORING PROGRAM IS TO DETERMINE THE SUCCESS OF WETLAND BUFFER PLANTINGS DURING THE FIRST 10 YEARS AFTER THE PROJECT IS INSTALLED. A QUALIFIED BIOLOGIST OR ECOLOGIST WILL MONTOR THE MITIGATION AREA FOR 10 YEARS FOLLOWING THE BASELINE MONITORING ON YEARS 1, 3, AND 5, TWICE YEARLY. THE PROPONENT SHALL, AS DIRECTED, BE REQUIRED TO PROVIDE THE CITY OF AUBURN BUILDING OFFICIAL WITH SERVICES OF AN APPROVED BIOLOGIST WITH EXPERTISE IN WETLANDS ENHANCEMENT AND CREATION, FOR PURPOSES OF INSPECTING WETLAND WORK ACTIVITIES FOR CONFORMANCE WITH APPROVED PLANS AND SPECIFICATIONS.

REPORTS FOLLOWING THE FIRST, OR BASELINE YEAR DOCUMENT, WILL INCLUDE A COMPARISON OF CHARACTERISTICS OBSERVED FOR EACH MONITORING COMPONENT AGANST THE BASELINE AND ANY OTHER PREVIOUS MONITORING EFFORTS. REPORTS WILL BE SUBMITTED BY OCTOBER 1 OF EACH MONITORING YEAR AS REQUIRED BY THE COE AND CITY OF AUBURN (AGENCIES). ALL AGENCIES WILL REVIEW THE RESULTS PRESENTED IN EACH MONITORING REPORT TO ASSESS COMPLIANCE WITH THE CONDITIONS AND PERFORMANCE STANDARDS ESTABLISHED INT HEP PLAN. UPON SUBMITTAL OF THE LAST MONITORING REPORT, THE AGENCIES WILL MEET WITH THE MONITORING TEAM TO DETERMINE IF THE MITIGATION IS IN COMPLIANCE. EXTENSION OF THE MONITORING PERIOD MAY BE WARRANTED IF THIS IS RECOMMENDED BY THE CONSULTING BIOLOGIST AND U.S. ARMY CORPS OF ENGINEERS STAFF. REPORTS WILL BE SENT TO All PARTIES INVOLVED IN THE PROJECT OVERVIEW. 6.3 FU tIONAL ASSEBM®4T- WETLANDS PROVIDE VALUABLE BENEFITS TO THE LANDSCAPES IN WHICH THEY EXIST, EACH WETLAND SERVES SOME FUNCTION THAT HAS SOME BENEFIT, ALTHOUGH THE TYPE AND DEGREE OF BENEFIT VARIES FROM WETLAND TO WETLAND. THE WASHINGTON STATE WETLAND FUNCTIONAL ASSESSMENT (WSDOE 1998), HEREINAFTER REFERRED TO AS ESFAM IS THE PREFERRED METHOD OF FUNCTIONAL EVALUATION AND IS THE METHOD THAT WILL BE USED AT EMERALD CORPORATE PARK. EACH EXISTING WETLAND AND CREATED WETLAND AREA WILL BE EVALUATED EACH YEAR MONITORING IS DONE IN ORDER TO DETERMINE IF POTENTIAL FUNCTIONAL PERFORMANCE HAS CHANGED OVER TIME. 5A BABIEUIE TRANBECT AND 8ALrLE PLOT PBATABLASAW A BASELINE TRANSECT WILL BE PLACED ALONG THE EASTERN EDGE OF THE ON -SITE MITIGATION AREA, INCLUDING THE BUFFER. PERPENDICULAR TRANSECTS WILL BE PLACED ACROSS THE SITE FROM THIS BASELINE EVERY 50 FEET, OR IN AREAS WHERE MONITORING SHOULD BE DONE. STATIONS WILL BE PLACED ALONG THESE TRANSECTS EVERY 25 FEET. STATIONS WILL BE MARKED WITH LATH OR STAKES TOPPED WITH PINK FLAGGING AND NUMBERED SO THAT THEY CAN BE EASILY LOCATED IN SUCCESSIVE YEARS. THIS WILL BE EXTENDED ONCE THE EASTERN SCALE HAS BEEN CLEANED OUT AND REPLANTED. DATA WILL BE COLLECTED AT EVERY STATION. THE SAMPLING LOCATIONS WILL BE INDICATED ON THE AS -BUILT PLANS SUBMITTED AS PART OF THE BASELINE MONITORING OF THE WETLAND. 5.5 VEGETATION ABBEBAEND SPEOCB COAPOBRION AND PIEICIEW COVM THE VEGETATION COMMUNITIES IN THE SAMPLE PLOTS ARE DESCRIBED IN TERMS OF SPECIES COMPOSITION AND PERCENT COVER. PLOTS ARE SAMPLED IN EACH AREA OF UNIFORM VEGETATION TYPE AND IN THE TRANSITION ZONES BETWEEN DIFFERENT COMMUNITY TYPES. THE ASSESSMENT IS PERFORMED AS FOLLOWS: A. THE VEGETATION COMMUNITY TYPE IS DETERMINED BY THE DOMINANT VEGETATION SPECIES. CIRCULAR PLOTS ARE ESTABLISHED WITH THE PLOT SIZE DEPENDENT ON THE COMMUNITY TYPE. A 2-METER RADIOS CIRCLE IS USED FOR EMERGENT AND SHRUB COMMUNITIES. B. THE PLANT SPECIES N EACH CIRCULAR PLOT ARE RECORDED. A VISUAL ESTIMATE OF THE PERCENT COVER OF EACH SPECIES IS RECORDED AS A COVER CLASS ESTIMATE. THE COVER CLASS SYSTEM USED FOR THIS STUDY IS A NINE -INCREMENT SCALE KNOWN AS OCTAVE SCALE (GAUCH 1962 . THE VEGETATION DATA TABLES ARE LOCATED IN APPENDIX A. THE OCTAVE SCALE (GAUCH 1962) FOR THE COVER CLASSES IS LISTED BELOW: 0 - SINGLE NOMDUAL 5 - 4-8X 1 - 0.5% 6 - 8-16% 2 - 0.5-1X 7 - 16-32X 3 - 1-2% 8 - 32-64X 4 - 2-4X 9 - >64X 5.1111 FLAW ► KAL71N AND OM WAL' PLANT HEALTH AND SURVIVAL WILL BE MEASURED AT THE VEGETATION STATIONS MENTIONED IN THE PREVIOUS SECTION. PLANT SURVIVAL WILL BE CALCULATED AS THE NUMBER OF DEAD PLANTS PER VEGETATION PLOT, DIVIDED BY THE TOTAL NUMBER OF PLANTS PLANTED N THE AREA OF THE VEGETATION PLOT, MULTIPLIED BY 100. THE FIRST MORTALITY COUNTS WILL BE MADE DURING THE MONITORING OF YEAR 1 POST -INSTALLATION. REPLACEMENT WILL OCCUR BY THE END OF THE GROWING SEASON OF THAT YEAR AND SUBSEQUENT MONITORING YEARS. IF MORE THAN 10 PERCENT MORTALITY OCCURS, THEN REPLACEMENT WILL BE REQUIRED AT THE END OF THE SEASON. PLANT SURVIVAL WILL BE MONITORED THROUGH YEAR 3. AFTER PUNT SURVIVAL IS MONITORED, PERCENT COVER AND SPECIES COMPOSITION WILL BE MEASURED. 5.7 M/ABNE PLANT COVER INVASIVE PLANT SPECIES HAVE BEEN IDENTIFIED ON THE EMERALD CORPORATE PARK. JAPANESE KNOTWEED (POLYGONUM CUSPIDATUM), REED CANARYGRASS (PKALARIS ARUNDINACEAE). BIRDSFOOT TREFOIL (LOTUS CORNICULATUS), SOFT RUSH (JUNCUS EFFUSUS), AND HIMALAYAN BLACKBERRY (RUBUS PROCERUS VAR. DISCOLOR) ARE OF SPECIAL CONCERN BECAUSE THEY ARE VERY INVASIVE ON THE SITE. THESE PLANTS WILL BE RECORDED WHILE VEGETATION STATIONS ARE BEING MONITORED. THE LOCATION OF ANY LARGE POPULATIONS OF THESE PLANTS ANYWHERE IN THE MITIGATION AREA (INCLUDING THE ASSOCIATED WET POND) WILL BE IDENTIFIED ON A MAR TO BE INCLUDED IN THE MONITORING REPORTS. ERADICATION MEASURES WILL ALSO BE DISCUSSED IN THE MONITORING REPORTS. 5B DATA ANALY110 VEGETATION SPECIES OCCURRENCES AND COMMUNITY CHANGES WILL BE ASSESSED USING THE DATA FROM EACH VEGETATION STATION DISCUSSED ABOVE FOR EACH YEAR, AND MAKING COMPARISONS TO DETERMINE IF CHANGES IN PRESENCE, COMPOSITION, OR PERCENT COVER HAVE OCCURRED. GRAPHS SHOWING VEGETATION COVER CHANGES BY YEAR WILL BE MADE TO ILLUSTRATE THE CHANGES. A COMPARISON WILL BE MADE OF WETLAND FUNCTIONAL ASSESSMENT RESULTS OF THE IMPACTED WETLANDS AND THE ENHANCED AND THE CREATED WETLANDS IN THE BACKWATER CHANNEL AREAS. ANY CHANGES IN THE FUNCTIONAL PERFORMANCE WILL BE NOTED. DECREASES IN WETLAND FUNCTION WILL BE EXAMINED TO DETERMINE IF CORRECTIVE ACTIONS ARE NECESSARY. INVASIVE SPECIES WILL BE MONITORED WHILE COLLECTING PRESENCE AND COVER DATA AT THE VEGETATION STATIONS. ADDITIONALLY, ANY LARGE POPULATIONS OF THESE SPECIES WILL BE IDENTIFIED BY LOCATION ON A MAR THAT WILL BE INCLUDED IN THE MONITORING REPORT. BBP► IM000AMWAIM PHOTO STATIONS WILL BE PLACED ALONG THE EDGES OF THE WETLAND MITIGATION AREA. THE PHOTO STATIONS WILL BE STAKED N THE FIELD AND A COMPASS BEARING WILL BE RECORDED AT EACH STATION SO THAT THE SAME VIEW IS PHOTOGRAPHED EACH MONITORING YEAR. THE LOCATIONS OF THESE STATIONS WILL BE SHOWN ON THE AS -BUILT DRAWINGS.
