PROJECT ELEMENTS, EXISTING CONDITIONS,MITIGATION SEQUENCING, AND PROJECT IMPACTS TO CRITICAL AREAS AREDISCUSSED IN THE CITY OF RENTON CRITICAL AREAS REPORT (RENTON CAR)PREPARED BY THE WATERSHED COMPANY, JANUARY 2019. THIS MITIGATION PLAN ISINTENDED TO REPRESENT THE MITIGATION PLAN REFERENCED IN THE RENTONCAR. IT HAS BEEN DESIGNED TO APPROPRIATELY MITIGATE FOR PROJECT IMPACTSOCCURRING IN WETLAND AND STREAM CRITICAL AREA BUFFERS AS DESCRIBED INTHE RENTON CAR AND REQUIRED BY THE RENTON MUNICIPAL CODE (RMC).PROPOSED PROJECT ACTIVITIES IMPACT WETLAND AND STREAM BUFFERS INTHREE POSSIBLE WAYS: PERMANENT IMPACTS RESULTING IN A CONVERSION TO ADEVELOPED CONDITION AS A RESULT OF POLE FOOTPRINTS, VEGETATIONCONVERSION FROM A FORESTED VEGETATION TYPE TO A SHRUB OR HERBACEOUSCOMMUNITY DUE TO VEGETATION MANAGEMENT REQUIREMENTS (CONVERSION),AND/OR TEMPORARY IMPACTS ASSOCIATED WITH CONSTRUCTION ACTIVITIES(TEMPORARY). TEMPORARY IMPACTS WILL BE RESTORED IN PLACE AFTERCONSTRUCTION WORK IS COMPLETE. CONVERSION AND PERMANENT BUFFERIMPACTS REQUIRE MITIGATION WHICH IS PRESENTED HEREIN.THE PROJECT HAS AVOIDED ALL DIRECT PERMANENT IMPACTS (FILL) TO WETLANDS,STREAMS AND STREAM BUFFERS. ONE NEW POLE WILL BE INSTALLED WITHIN AWETLAND BUFFER AND THREE REPLACEMENT POLES WILL BE INSTALLED IN THESAME LOCATION AS EXISTING POLES WITHIN A WETLAND BUFFER, BUT WITH ALARGER FOOTPRINT. TWO EXISTING TRANSMISSION POLES WILL BE REMOVEDFROM WETLAND BUFFER, RESULTING IN AN OVERALL NET INCREASE OF ONLY 68 SFOF FILL MATERIAL IN BUFFER AREAS.VEGETATION CONVERSION (TREE REMOVAL) IMPACTS OCCUR IN THE BUFFER AREAOF THREE WETLAND AND THREE STREAM FEATURES AND ARE NECESSARY TOACCOMMODATE THE NEW 230KV TRANSMISSION LINE DESIGN AND MEET FEDERALSAFETY STANDARDS.MITIGATION FOR IMPACTS IS PLANNED IN THE BUFFER OF WETLAND NRO1 IN THELOWER CEDAR RIVER SUB-BASIN (TALBOT SITE). AS DISCUSSED IN THE RENTONCAR, THIS LOCATION WAS SELECTED FOR MITIGATION ACTIVITIES BASED UPON THELOCATION OF PROJECT IMPACTS, OPPORTUNITY PRESENT, PROPERTY OWNERSHIP,PROXIMITY TO OTHER REGULATED CRITICAL AREAS, AND THE VALUE OF THEENHANCMENT TO OVERALL CRITICAL AREA FUNCTION IN THE CORRIDOR.ADDITIONALLY, SNAG CREATION IS PROPOSED IN THE BUFFER OF HONEY DEWCREEK TO MITIGATE FOR SOME IMPACTS TO HABITAT OCCURING WITHIN THE MAYCREEK SUB-BASIN.THE MINIMUM MITIGATION AREA REQUIRED, AS PRESENTED IN THE RENTON CAR IS9,461 SF. THIS WAS CALCULATED BASED ON A PERMANENT IMPACT MITIGATIONRATIO OF 1:1 AND A VEGETATION CONVERSION MITIGATION RATIO OF 0.5:1 BASEDON ECOLOGY GUIDANCE.A TOTAL AREA OF APPROXIMATELY 9,500 SF OF DEGRADED BUFFER WILL BEENHANCED ON THE TALBOT SITE. THE ENHANCEMENT AREAS INCLUDE INVASIVESPECIES REMOVAL AND INSTALLATION OF NATIVE TREES, SHRUBS, ANDGROUNDCOVER PLANTS.OVERVIEWTHE MITIGATION PLAN CONSISTS OF APPROXIMATELY 9,500 SF OF WETLAND NRO1BUFFER ENHANCEMENT ON THE TALBOT SITE, PLUS SNAG AND HINGE-CUT TREECREATION IN THE BUFFER OF HONEY DEW CREEK. THE MITIGATION PLAN INCLUDESA COMPREHENSIVE FIVE-YEAR MAINTENANCE AND MONITORING PLAN, PER RMC4-3-50.L.3. THE PLAN SPECIFIES APPROPRIATE SPECIES FOR PLANTING ANDPLANTING TECHNIQUES, DESCRIBES PROPER MAINTENANCE ACTIVITIES, AND SETSFORTH PERFORMANCE STANDARDS TO BE MET YEARLY DURING MONITORING.THESE SPECIFICATIONS AND STANDARDS WILL ENSURE THATENHANCEMENT/RESTORATION PLANTINGS WILL BE MAINTAINED, MONITORED, ANDSUCCESSFULLY ESTABLISHED WITHIN THE FIRST FIVE YEARS FOLLOWINGIMPLEMENTATION.BUFFER ENHANCEMENT WILL INCLUDE REMOVAL OF INVASIVE SPECIES,INSTALLATION OF NATIVE TREES, SHRUBS, AND GROUNDCOVER, AND CREATION OFHABITAT SNAGS AND HINGE-CUT TREES FROM SUITABLE TREES PROPOSED FORREMOVAL FROM THE HONEY DEW CREEK BUFFERTHESE MITIGATION ACTIVITIES ARE INTENDED TO INCREASE NATIVE PLANT COVER,DECREASE INVASIVE SPECIES PREVALENCE, IMPROVE NATIVE SPECIES DIVERSITY,AND PROVIDE FOOD AND OTHER HABITAT RESOURCES FOR WILDLIFE.GOALS1.ENHANCE DEGRADED CRITICAL AREA BUFFER.a.ESTABLISH DENSE AND DIVERSE VEGETATION COMMUNITIES THROUGHOUTTHE MITIGATION AREA.b.INCREASE SPECIAL HABITAT FEATURES IN BUFFER AREAS THROUGHCREATION OF HABITAT SNAGS AND HINGE-CUT TREES.PERFORMANCE STANDARDS (TALBOT SITE)THE STANDARDS LISTED BELOW WILL BE USED TO JUDGE THE SUCCESS OF THEPLAN OVER TIME.
