MONITORING NOTES & MAINTENANCE PLAN
1.0 MONITORING PROGRAM
THIS PLAN INCLUDES A SYSTEMATIC MONITORING PROGRAM OF THE ENHANCED &
RESTORED WETLAND BUFFER TO EVALUATE THE SUCCESS OF THE MITIGATION EFFORT.
THE RESULTS OF THE MONITORING WILL BE USED TO DEVELOP ANY NEEDED
MODIFICATIONS AND/OR ALTERATIONS OF THE SITE IN SUBSEQUENT YEARS.
THE PURPOSES OF THE MONITORING PROGRAM ARE: (1) TO DOCUMENT PHYSICAL AND
BIOLOGICAL CHARACTERISTICS OF THE MITIGATION AREA, AND (2) TO ENSURE THAT THE
GOALS AND OBJECTIVES COMPLY WITH PERMIT SPECIFICATIONS.
THE MONITORING PROCESS WOULD CONSIST OF THREE DISTINCT PHASES: (1)
CONSTRUCTION MONITORING; (2) COMPLIANCE MONITORING; AND (3) LONG-TERM
MONITORING. THE "TIME -ZERO" OR BASELINE COMPOSITION, STRUCTURE, AND COVER
ABUNDANCE WOULD BE DOCUMENTED DURING THE COMPLIANCE MONITORING PHASE.
THE LONG-TERM MONITORING PROGRAM WOULD DOCUMENT THE SURVIVAL OF PLANTED
VEGETATION AND RATES OF COLONIZATION BY OTHER PLANTS (I.E., IN PLANTED AREAS)
OVER A THREE-YEAR PERIOD AFTER INSTALLATION OF THE BUFFER MITIGATION HAS BEEN
COMPLETED.
THE FOLLOWING SECTIONS DESCRIBE THE ELEMENTS OF AN EFFECTIVE MONITORING
PROGRAM.
1.1 CONSTRUCTION MONITORING
THE PROJECT BIOLOGIST WOULD BE PRESENT ON -SITE DURING THE VARIOUS STAGES OF
CONSTRUCTION IN ORDER TO: (1) DEMARK THE LIMITS OF THE AREAS TO BE PLANTED; (2)
REVIEW AND APPROVE THE PLANT MATERIALS AND RECOMMEND THEIR FINAL PLACEMENT
BEFORE PLANTING; (3) MAKE ADJUSTMENTS IN PLANTING PLANS, AS NEEDED, IN
RESPONSE TO FIELD CONDITIONS; (4) ENSURE THAT CONSTRUCTION ACTIVITIES ARE
CONDUCTED PER THE APPROVED PLAN; AND (5) RESOLVE PROBLEMS THAT ARISE DURING
CONSTRUCTION, THUS LESSENING PROBLEMS THAT MIGHT OCCUR LATER DURING THE
LONG-TERM MONITORING PHASE.
1.2 COMPLIANCE MONITORING
COMPLIANCE MONITORING CONSISTS OF EVALUATING THE BUFFER ENHANCEMENT &
RESTORATION AREAS IMMEDIATELY AFTER ALL FEATURES OF THE MITIGATION PLAN HAVE
BEEN INSTALLED BY THE CONTRACTOR. THE OBJECTIVES WOULD BE TO CERTIFY THAT
ALL DESIGN FEATURES, AS AGREED TO IN THE PLANTING PLAN, HAVE BEEN CORRECTLY
AND FULLY IMPLEMENTED, AND THAT ANY CHANGES MADE IN THE FIELD ARE CONSISTENT
WITH THE INTENT OF THE DESIGN. EVALUATION OF THE PLANTING AREAS AFTER
IMPLEMENTATION WOULD BE DONE BY THE BIOLOGIST USING PERFORMANCE STANDARDS
ON SHEET WL-1.
THE COMPLIANCE MONITORING PHASE WOULD CONCLUDE WITH THE PREPARATION OF A
BRIEF COMPLIANCE REPORT BY THE BIOLOGIST. THE REPORT WOULD VERIFY THAT ALL
DESIGN FEATURES HAVE BEEN CORRECTLY, FULLY, AND SUCCESSFULLY INCORPORATED.
SUBSTANTIVE CHANGES MADE IN THE PLANTING PLANS WOULD BE NOTED IN THE
COMPLIANCE REPORT AND ON THE DRAWINGS FOR USE DURING THE LONG-TERM
MONITORING PHASE. DOCUMENTATION OF PLAN CHANGES SHOULD INCLUDE WHAT WAS
DONE, WHERE, WHY, AT WHOSE REQUEST, AND THE RESULT OF THE CHANGE. LOCATIONS
OF MONITORING STATIONS ESTABLISHED FOR THE COMPLIANCE MONITORING WOULD BE
IDENTIFIED ON THE AS -BUILT PLANS.
THE PLANTING PLANS, WITH THE COMPLIANCE REPORT, WOULD DOCUMENT "AS -BUILT"
CONDITIONS AT THE TIME OF CONSTRUCTION COMPLIANCE. A QUANTITATIVE
ASSESSMENT OF THE PLANTS ESTABLISHED IN THE BUFFER ENHANCEMENT AND
RESTORATION AREA WOULD BE RECORDED AT REPRESENTATIVE SAMPLE PLOTS FOR
BASELINE DATA. THIS INFORMATION WOULD BE USED TO DOCUMENT "TIME -ZERO"
CONDITIONS FROM WHICH THE LONG-TERM MONITORING PERIOD WOULD BEGIN. THE
COMPLIANCE REPORT AND AS -BUILT DRAWINGS WOULD BE SUBMITTED TO THE CITY OF
AUBURN.
1.3 LONG-TERM MONITORING
LONG-TERM MONITORING WOULD BE CONDUCTED OVER THREE GROWING SEASONS
FOLLOWING APPROVAL OF THE COMPLIANCE REPORT AND AS -BUILT PLAN BY THE CITY.
LONG-TERM MONITORING WOULD EVALUATE THE ESTABLISHMENT AND MAINTENANCE OF
THE PLANT COMMUNITIES IN THE ENHANCED WETLAND BUFFER TO DETERMINE IF THE
GOALS AND OBJECTIVES OF THE MITIGATION PLAN HAVE BEEN MET.
A TOTAL PLANT COUNT OF INSTALLED PLANTS WITHIN THE ENHANCED BUFFER WOULD BE
MADE DURING EACH YEAR AND PERMANENT SAMPLE PLOTS IN THE RESTORED BUFFER
WOULD BE ESTABLISHED TO DOCUMENT THE PERCENT SURVIVAL OF EACH PLANTED
SPECIES. PLANT IDENTIFICATIONS WOULD BE MADE ACCORDING TO STANDARD
TAXONOMIC PROCEDURES DESCRIBED IN HITCHCOCK AND CRONQUIST (1976), WITH
NOMENCLATURE AS UPDATED BY THE U.S. ARMY CORPS OF ENGINEERS NATIONAL
WETLAND PLANT LIST (LICHVAR AND KARTESZ 2009). SIGNS OF PLANTING STRESS OR
DAMAGE, PRESENCE OF INVASIVE SPECIES, AS WELL AS SIGNS OF VIGOR, AND RATES OF
COLONIZATION BY OTHER PLANTS (I.E., IN BARE SOIL AREAS) WOULD BE DOCUMENTED
DURING EACH YEAR OF THE LONG-TERM MONITORING.
PHOTOS WOULD BE TAKEN ANNUALLY TO PROVIDE PHYSICAL DOCUMENTATION OF THE
CONDITION OF THE MITIGATION AREAS. PHOTOGRAPHS WOULD BE TAKEN FROM ALL
LOCATIONS ESTABLISHED DURING THE COMPLIANCE MONITORING SITE VISIT AND EACH
YEAR THEREAFTER OF THE MONITORING PERIOD FROM THE ESTABLISHED LOCATION
POINTS.
1.4 MONITORING AND REPORTING SCHEDULE AND CONTENTS
FORMAL MONITORING OF THE ENHANCED AND RESTORED BUFFER WOULD OCCUR AFTER
THE SEASON'S GROWTH IS VIRTUALLY COMPLETE (RECOMMENDED DURING AUGUST OR
SEPTEMBER). IN ADDITION, SPRING AND MID -SUMMER SITE CHECKS WOULD BE
CONDUCTED DURING EACH YEAR OF THE THREE-YEAR LONG-TERM MONITORING PERIOD
TO ASSESS SITE PROGRESS AND TO DETERMINE WHETHER SITE MAINTENANCE IS NEEDED
MONITORING REPORTS WOULD BE PREPARED FOLLOWING THE COMPLETION OF THE
GROWING SEASON OF EACH YEAR OF THE THREE-YEAR LONG-TERM MONITORING PERIOD
FOR SUBMITTAL TO THE CITY OF AUBURN. MONITORING REPORTS WILL INCLUDE THE
REQUIRED INFORMATION FOUND IN THE MONITORING REPORT CHECKLIST FROM THE
WASHINGTON STATE DEPARTMENT OF ECOLOGY. THE LONG-TERM MONITORING PERIOD
WILL COMMENCE FOLLOWING ACCEPTANCE OF THE COMPLIANCE REPORT AND "AS -BUILT"
DRAWINGS BY THE CITY OF AUBURN.
MONITORING REPORTS WOULD BE SUBMITTED FOR REVIEW AND APPROVAL BY THE CITY OF
AUBURN AS SOON AS POSSIBLE AFTER THE MONITORING HAS BEEN COMPLETED, WITH A
TARGET DATE OF DECEMBER 1 OF EACH MONITORING YEAR. THE REPORT WOULD
DOCUMENT CONDITIONS WITHIN THE ENHANCED & RESTORED AREAS AND MAKE
RECOMMENDATIONS FOR CORRECTING ANY PROBLEMS ENCOUNTERED.
2.0 CONTINGENCY PLAN
CONTINGENCY PLANS ARE NEEDED IF POST -MITIGATION MONITORING SHOWS THAT OBJECTIVES AND
PERFORMANCE STANDARDS HAVE NOT BEEN MET. IT SHOULD BE NOTED, HOWEVER, THAT IT IS NOT
POSSIBLE TO DEVELOP A DETAILED CONTINGENCY PLAN UNTIL THE SPECIFIC PROBLEMS THAT NEED
TO BE ADDRESSED ARE KNOWN. IT WOULD BE UNPRODUCTIVE TO TRY TO ANTICIPATE ALL POSSIBLE
PROBLEMS AND THEIR SOLUTIONS AT THIS TIME.
COMMON PROBLEMS, BOTH HUMAN AND NATURAL, THAT MIGHT ARISE CAN BE IDENTIFIED AND
GENERAL RECOMMENDATIONS FOR REMEDY PROPOSED. FOR EXAMPLE, AFTER THE SECOND YEAR,
PLANT COMMUNITIES WITHIN THE RESTORED AND ENHANCED AREAS MAY NOT BE ESTABLISHED AT
ACCEPTABLE LEVELS. IT MAY BE NECESSARY TO REPLANT WITH NEW OR DIFFERENT STOCK, PROVIDE
ADDITIONAL WATERING OR IRRIGATION DURING CRITICAL SEASONS, OR AUGMENT THE SOIL.
THE CONTINGENCY PLAN MAY REQUIRE EXTENSION OF THE MONITORING PHASE OF THE PROJECT,
ESPECIALLY IF MAJOR CHANGES IN THE PLAN ARE REQUIRED. IF, AT THE END OF THE LONG-TERM
MONITORING PERIOD, PERFORMANCE STANDARDS FOR YEAR THREE HAVE NOT BEEN MET, IDENTIFIED
PROBLEMS WILL BE ADDRESSED, AND ADDITIONAL MONITORING WILL BE CONDUCTED DURING AN
ADDITIONAL MONITORING YEAR(S) AS RECOMMENDED BY THE PROJECT BIOLOGIST AND APPROVED BY
THE CITY OF AUBURN.
3.0 MAINTENANCE
3.1 IRRIGATION
SUPPLEMENTAL WATER WILL BE PROVIDED TO ALL TREE AND SHRUB PLANTINGS DURING THE
FIRST TWO GROWING SEASONS FOLLOWING INSTALLATION. HAND WATERING OR A TEMPORARY
IRRIGATION SYSTEM MAY BE USED. IRRIGATION WILL OCCUR FROM MAY 1 THROUGH SEPTEMBER
30 OR OTHER PERIODS OF HOT, DRY WEATHER AND WILL DELIVER APPROXIMATELY 1 INCH OF
WATER PER WEEK THROUGHOUT THE BUFFER ENHANCEMENT AREA. IF WATERED BY HAND, THEN
THE MINIMUM WATERING REQUIREMENTS WILL BE 1 TO 3 GALLONS OF WATER FOR SMALL SHRUBS
AND 3 TO 5 GALLONS PER WEEK FOR SAPLING TREES AND LARGE SHRUBS. THESE MINIMUM
REQUIREMENTS ARE GUIDELINES THAT MAY VARY DEPENDING ON PLANT LOCATION, EXPOSURE,
SOIL CONDITION, AND PRESENCE OF EXISTING VEGETATION. ANY EROSION WILL BE RECTIFIED
IMMEDIATELY UPON DISCOVERY.
3.2 SITE MAINTENANCE
THE ENHANCED/RESTORED BUFFER IS DESIGNED TO BE SELF-SUSTAINING. TO ENSURE THE
SUCCESS OF THE PLANTINGS, ADDITIONAL REPLANTING AND CONTROL OF UNDESIRABLE PLANT
SPECIES MAY BE NECESSARY AFTER INITIAL INSTALLATION. THIS MAINTENANCE PLAN INCLUDES
ALL ACTIONS REQUIRED TO MAINTAIN PLANTS FREE OF INSECTS AND DISEASE, CONTROL
COMPETITION WITH GRASSES AND WEEDS, AND LIMIT DIE -BACK OR MORTALITY DUE TO
INADEQUATE SOIL MOISTURE TO WITHIN PERFORMANCE STANDARDS SPECIFIED ON SHEET WL-1.
UPON COMPLETION OF INSTALLATION OF THE BUFFER ENHANCEMENT PLANTINGS, MULCH AND
ALL OTHER ITEMS SPECIFIED BY THE BUFFER ENHANCEMENT PLAN, ALL SURPLUS MATERIAL,
EQUIPMENT, AND DEBRIS SHALL BE REMOVED FROM THE MITIGATION SITE. ALL SILT FENCES WILL
BE REMOVED FROM WITHIN THE ENHANCED/RESTORED BUFFER ONCE THE AS -BUILT PLAN HAS
BEEN APPROVED BY THE CITY OF AUBURN OR AS REQUESTED BY THE CITY OF AUBURN.
THE SITE MAINTENANCE PROGRAM WOULD COMMENCE UPON APPROVAL OF THE COMPLIANCE
REPORT AND AS -BUILT PLAN BY THE CITY. THE SITE WOULD BE REGULARLY MAINTAINED FOR THE
DURATION OF THE LONG-TERM MONITORING PERIOD. THE PROJECT BIOLOGIST WOULD INSPECT
THE SITE DURING SPRING (MARCH-APRIL) AND MID -SUMMER (JUNE-JULY) DURING EACH YEAR OF
THE LONG-TERM MONITORING PERIOD TO IDENTIFY ANY DEVELOPING PROBLEMS WITHIN THE
MITIGATION SITE. ITEMS TO BE EVALUATED WITHIN THE BUFFER ENHANCEMENT AND
RESTORATION AREAS INCLUDE IRRIGATION SYSTEM OPERABILITY (IF APPLICABLE), PRESENCE OF
INVASIVE SPECIES, PLANT HEALTH, ANIMAL DAMAGE TO PLANTINGS, CONDITION OF NGPA FENCE,
PRESENCE OF INSTALLED NGPA SIGNS AND PRESENCE OF TRASH.
THE PROJECT BIOLOGIST WOULD SUBMIT A WRITTEN SUMMARY OF HIS/HER FINDINGS ALONG WITH
MAINTENANCE RECOMMENDATIONS TO THE PROJECT PROPONENT AND THE CITY WITHIN 7 DAYS
AFTER COMPLETION OF HIS/HER INSPECTION. MAINTENANCE RECOMMENDATIONS WOULD BE
IMPLEMENTED BY THE PROJECT PROPONENT WITHIN 14 DAYS OF RECEIPT FROM THE PROJECT
BIOLOGIST.
INVASIVE SPECIES WOULD BE CONTROLLED BY METHODS THAT DO NOT COMPROMISE THE REST
OF THE BUFFER PLANTINGS. UNLESS OTHERWISE AUTHORIZED BY THE PROJECT BIOLOGIST,
REMOVAL OF INVASIVE SPECIES WILL BE DONE BY HAND, WITH HAND PULLING OF ALL WEEDS
WITHIN THE DRIP RING OF ANY INSTALLED SHRUB OR TREE. NO WEED -WHIPPING WITH
MECHANIZED LINE TRIMMERS WILL BE ALLOWED BETWEEN WOODY PLANTS WITHIN CLUSTER OR
CLUMPED PLANTINGS.
4.0 PROJECT ACCEPTANCE
AFTER COMPLETION OF THE THREE-YEAR MONITORING PERIOD AND CONFIRMATION BY THE CITY OF
AUBURN THAT THE BUFFER ENHANCEMENT HAS SUCCESSFULLY MET THE PERFORMANCE STANDARDS,
THE CITY OF AUBURN SHALL PROVIDE WRITTEN ACCEPTANCE AND APPROVAL OF THE BUFFER
ENHANCEMENT SIT AND RELEASE ALL BONDS IN PLACE AS GUARANTEE OF MITIGATION SITE
CONSTRUCTION AND PERFORMANCE.
5.0 CONSERVATION EASEMENT
THE BUFFER ENHANCEMENT AREA WILL BE RECORDED AS A CONSERVATION EASEMENT PRIOR TO
CERTIFICATE OF OCCUPANCY.
6.0 MITIGATION ASSURANCE
A PERFORMANCE AND MAINTENANCE SECURITY IS REQUIRED TO ENSURE THE APPLICANT'S
COMPLIANCE WITH THE TERMS OF THE APPROVED MITIGATION PLAN. THE AMOUNT OF THE
PERFORMANCE SECURITY SHALL EQUAL 125 PERCENT OF THE COST OF THE MITIGATION PROJECT FOR
THE LENGTH OF THE MONITORING PERIOD; THE DIRECTOR MAY AGREE TO REDUCE THE SECURITY IN
PROPORTION TO WORK SUCCESSFULLY COMPLETED OVER THE PERIOD OF THE SECURITY.

of 10 lbs. per 1000 square feet. Apply hydro -seed mulch at a rate of 40 lbs.
per 1000 square feet and binding agent at a rate of 1 lb. per 1000 square feet.
Reseed any areas which do not germinate within 14 days.
13. Seeded or Sodded Lawn Areas: Lawn installation shall occur upon completion of finish grading,
planting and mulch installation. Seeding or sodding to occur only when the soil conditions
are dry and free of surface water. Carefully water lawn areas after installation.
Sodded Lawn Areas: Install a northwest hardy, blended grass sod within 12 hours of delivery
to site. Lay sod tight with no gaps, allowing for shrinkage. Apply a 10-20-10 fertilizer
at a rate of 10 lbs. per 1000 square feet prior to installation.
Seeded Lawn Areas: Seed shall consist of a Perennial Rye Grass blend and applied
at a rate of 10 lbs per 1000 square feet. Apply a 10-20-10 fertilizer at a rate
at a rate of 10 lbs per 1000 square feet. Promptly re -seed any areas which do not
germinate with 14 days of planting.
14. Provide landscape maintenance immediately after planting and continue until final
acceptance. Work shall include watering, spraying, fertilizing, pruning, resetting of plants,
restoring eroded areas, adjustments to staking and removal of weeds/debris as required
for healthy plant growth.
15. Inspection And Acceptance: The owner will make an inspection for Substantial Completion
of the work upon request by the Contractor.
16. Replacement of Plantings: Remove any plant from site that is either dead, or in
unsatisfactory condition as determined by the owner or Landscape Architect. Replace with
a new planting of equal size and species as soon as conditions permit within the normal
planting season. All replacement plantings are then to be under re -instated guarantee period
as specified. Identify those replacements and take whatever measures necessary to prevent
similar demise of additional plant material.
17. Provide root barrier in a surround or linear pattern for tree plantings when trunk is located
within five (5) linear feet of any paved surface. DeepRoot Universal Barrier #U1318-2
(or approved equal). Install per manufacturer's recommendations.
WARRANTY:
This Warranty shall include replacing and planting the same size and species
of plant material, as shown on the Landscape Plan and that has been designated, by
the Landscape Architect, to be replaced. Except for loss due to excessively severe
climatological conditions (20 year weather charts), installed plant materials are required
to be guaranteed until the end of one growing season against defects and unsatisfactory
growth, except for cases of neglect or abuse by the owners or others. All plants replaced
shall be re -instated under these plant guaranty conditions.
LANDSCAPE NARRATIVE:
THE INTENT OF THE PLANTING DESIGN WILL BE TO PROVIDE A VISUALLY
INTERESTING AND AESTHETICALLY PLEASING LANDSCAPE THAT HARMONIZES
WITH THE ADJACENT STREETSCPES AND SURROUNDING NEIGHBORHOODS.
EMPHASIS WILL BE PLACED ON PLANTINS THAT DEMONSTRATE DROUGHT
TOLERANCE, ARE EASILY MAINTAINABLE, PROVIDE FOUR SEASONS OF
INTEREST, AND THRIVE IN THE PUGET SOUND CLIMATE. WHERE NEEDED
PLANTS WILL BE USED TO SCREEN OUT INCOMPATIBE OR UNDESIREABLE
VIEWS, CREATE PRIVACY, REDUCE THE VISUAL SCALE OF BUILDINGS, AND
SHADE PARKING AREAS. INTERNAL STREET TREES HAVE BEEN SELECTED
FROM THE MATER LANDSCAPE PLAN FOR SINGLE FAMILY DEVELOPMENTS.
LANDSCAPE NOTES:
FOR PURPOSES OF THIS PLAN, THE TREE LOCATIONS SHOWN WITHIN OR
ADJACENT TO THE RIGHT-OF-WAY ARE REPRESENTATIVE OF DESIREABLE
SPACING AND ARE NOT MEANT TO PRESCRIBE THE EXACT LOCATION SINCE
THE EXACT LOCATION OF DRIVEWAYS, FIRE HYDRANTS, STREET LIGHTS,
UNDERGROUND UTILTIES AND MAILBOXES AND OTHER INFRASTRUCTURE
FEATURES ARE NOT CURRENTLY KNOWN OR REASONABLY CAPABLE OF BEING
ASCERTAINED. THE STREET TREES AND THEIR PLANTING WILL BE EVALUATED
BY THE LANDSCAPE ARCHITECT AT THE TIME OF INSTALLATION FOR LOCATION
IN RELATION TO ALL DRIVEWAYS, FIRE HYDRANTS, STREET LIGHTS,
UNDERGROUND UTILITIES AND MAILBOXES, ETC. TREE LOCATIONS MUST BE
ADJUSTED TO BE COMPATIBLE WITH INFRASTRUCTURE FEATURES AND
MINIMIZE CONFLICTS. ADJUSTED TREE LOCATIONS SHALL GENERALLY
PROVIDE FOR SIMILAR NUMBER OF TREES AS SHOWN ON THIS PLAN AND
APPROXIMATE TREE SPACING OF 30 FEET. A MINIMUM OF ONE TREE SHALL BE
PROVIDED PER LOT UNLESS THE LOT'S FRONTAGE IS LESS THAN 40 FEET.
ALL TREES SHALL BE INSTALLED AND BE HEALTHY AND IN A UNDAMAGED
CONDITION PRIOR TO REQUESTING THE RELEASE OF PERFORMANCE SECURITY
HELD BY THE CITY TO GUARANTEE CONFORMANCE WITH CITY STANDARDS AND
PLAT REQUIREMENTS. FAILURE TO MAINTAIN, OR DAMAGE TO THE TREE(S)
DURING SUBSEQUENT CONSTRUCTION ON THE INDIVIDUAL LOTS WILL RESULT
IN A REQUIREMENT TO REPLACE THE TREE(S) PRIOR TO FINAL INSPECTION OF
THE STRUCTURE ON THE LOT.
