HomeMy WebLinkAboutLarge FormatSEWALL WETLAND CONSULTING INC. CONDUCTED A WETLAND DELINEATION ON THE
PROJECT AREA ON DECEMBER 3, 2013 AND JANUARY 8, 2014. THE SITE ENCOMPASSES
APPROXIMATELY 9.73 ACRES, WEST OF 108TH AVENUE SE IN THE CITY OF RENTON,
WASHINGTON (SECTION 32, TOWNSHIP 23N, RANGE 8E, W.M.).
THE PROJECT AREA IS PARTIALLY DEVELOPED, CONTAINING TWO SINGLE-FAMILY HOMES
WITH ASSOCIATED LAWNS AND ORNAMENTAL LANDSCAPING, GRAVEL DRIVEWAYS, THREE
OUT BUILDINGS, AND A LARGE UNMAINTAINED PASTURE. THE SITE CONTAINS SOME INTACT
FORESTED AREA ON ITS SOUTHWESTERN SIDE AND IS ADJACENT TO A HISTORICALLY
DISTURBED FOREST. THERE ARE REMNANT STUMPS FROM HISTORICAL LOGGING ALONG THE
WESTERN SIDE OF THE SUBJECT AREA. THE PROPERTY DISPLAYS A GENERAL WESTERN
ASPECT, WITH THE WESTERN EDGE SLOPING DOWN TOWARD PANTHER CREEK.
SURROUNDING LAND USE IS COMPRISED OF SINGLE-FAMILY RESIDENTIAL DEVELOPMENT TO
THE EAST, NORTH, AND SOUTH. THE PROJECT AREA IS BOUND ON THE WEST BY IMMATURE
FOREST, AND A DEEP GULCH IN WHICH PANTHER CREEK FLOWS. THE PROPERTY IS ZONED
BY THE CITY OF RENTON AS R-8, RESIDENTIAL.
TWO STREAMS (PANTHER CREEK AND UNNAMED STREAM A) AND FIVE WETLANDS (WETLAND
A THROUGH E) ARE LOCATED ON OR WITHIN 200 FEET OF THE PROJECT AREA. THE
WETLAND AREAS ARE EMERGENT SLOPE -TYPE WETLANDS. THE VEGETATION IN THE
WETLAND AREAS ARE DOMINATED BY HIMALAYAN BLACKBERRY, REED CANARYGRASS, SOFT
RUSH, AND CREEPING BUTTERCUP. THE NON -WETLAND FORESTED AREAS ARE DOMINATED
BY IMMATURE RED ALDER AND BIG LEAF MAPLE, WITH A DENSE UNDERSTORY OF HIMALAYAN
BLACKBERRY, SWORD FERN, INDIAN PLUM, ELDERBERRY AND STINGING NETTLE. THE
HIGHER UPLAND AREA IN THE EASTERN PORTION OF THE SITE IS ABANDONED PASTURE AND
LAWN AREAS DOMINATED BY A MIX OF PASTURE GRASSES INCLUDING ORCHARD GRASS, TALL
FESCUE, BENTGRASS AND QUACKGRASS.
UNDER RENTON MUNICIPAL CODE (RMC), CHAPTER 4.3.050, THE ON-SITE WETLANDS ARE
ALL CLASSIFIED AS CATEGORY 3. CATEGORY 3 WETLANDS TYPICALLY RECEIVE 25 -FOOT
PROTECTIVE BUFFERS. PANTHER CREEK, WHICH FLOWS SOUTH TO NORTH OFF-SITE, IS
IDENTIFIED ON WDFW'S SALMON DISTRIBUTION MAP AS HABITAT FOR COHO SALMON, WHICH
GRANTS THIS STREAM CLASS -2 DESIGNATION AS DESCRIBED IN THE CITY OF RENTON STREAM
CLASSIFICATION SECTION. CLASS 2 STREAMS TYPICALLY RECEIVE 100 -FOOT PROTECTIVE
BUFFERS. UNNAMED STREAM A IS AN INTERMITTENTLY FLOWING, NON-FISHBEARING
STREAM AND THEREFORE IS CLASSIFIED AS CLASS 4. CLASS 4 STREAMS TYPICALLY RECEIVE
35 -FOOT BUFFERS. WHEN TWO OR MORE BUFFERS OVERLAP, THE MORE RESTRICTIVE
BUFFER IS APPLIED.
U MO] 261401,011111 RI *TTWO-IMMI
GREEN LEAF- LAROSA LLC, HEREAFTER REFERRED TO AS THE APPLICANT, IS PROPOSING TO
CONSTRUCT A 34 -PLAT SINGLE-FAMILY RESIDENTIAL DEVELOPMENT AND ASSOCIATED
INFRASTRUCTURE ON THE 9.73 -ACRE PROJECT AREA.
IN JANUARY 2014, SEWALL WETLAND CONSULTING INC. PROVIDED A WETLAND MITIGATION
PLAN AND CRITICAL AREA STUDY FOR THE PROPOSED PROJECT. AS A RESULT OF A NEW
PLAT LAYOUT, WETLAND RESOURCES INC. IS PROVIDING A REVISED WETLAND MITIGATION
PLAN TO REFLECT THE MODIFIED SITE PLAN. THE PROJECT WILL BE SUBMITTED TO THE
ARMY CORPS OF ENGINEERS FOR REVIEW.
TO ACCOMMODATE THIS DEVELOPMENT, THE APPLICANT IS PROPOSING TO FILL WETLAND -E
AS PART OF THIS DEVELOPMENT ACTIVITY, A CATEGORY III WETLAND PER CITY OF RENTON
CLASSIFICATION (WASHINGTON DEPARTMENT OF ECOLOGY CATEGORY IV CLASSIFICATION) A
TOTAL OF 0.023 ACRES (996 SQUARE FEET) OF WETLAND FILL IS PROPOSED. THE SUBJECT
WETLAND IS LOCATED IN WRIA 9 (DUWAMISH-GREEN RIVER WATERSHED). THERE IS ONE
SMALL INTERMITTENTLY FLOWING CLASS 4 STREAM LOCATED ALONG THE SOUTHEAST SIDE
OF THE PROJECT AREA. PANTHER CREEK, A CLASS 2 STREAM, LIES ADJACENT TO THE
WESTERN SIDE OF THE PROJECT AREA, AND IS LOCATED ENTIRELY OFF-SITE.
AS COMPENSATION FOR THIS FILL, THE APPLICANT IS PROPOSING TO ENHANCE 7,774
SQUARE FEET OF WETLAND -A. THIS EXCEEDS THE DEPARTMENT OF ECOLOGY'S STANDARD
OF A 6:1 ENHANCEMENT RATIO FOR WASHINGTON DEPARTMENT OF ECOLOGY RATED
CATEGORY IV WETLANDS. THE USE OF ENHANCEMENT OF WETLAND -A AT A 7.8:1 RATIO
WILL IMPROVE AN EXISTING DEGRADED LOW VALUE WETLAND, AND CREATE AN AREA WITH
A FORESTED AND EMERGENT PLANT COMMUNITY WITH ENHANCED FUNCTIONAL VALUE.
THE ENHANCING OF WETLAND A WILL PROVIDE A FUNCTIONAL LIFT (RAISING THE WADOE
CATEGORY FROM A IV TO A CATEGORY III WETLAND) THROUGH ENHANCED WILDLIFE
HABITAT FUNCTION. THIS ENHANCEMENT WILL MITIGATE FOR THE LOST FUNCTIONS OF
THE SMALL LOW VALUE WETLAND TO BE FILLED.
THE CONSTRUCTION AND ASSOCIATED GRADING FOR A STORMWATER DETENTION POND ON
THE SOUTHWEST CORNER OF THE PROJECT AREA WILL RESULT IN 1,465 SQUARE FEET OF
TEMPORARY BUFFER IMPACT. HIMALAYAN BLACKBERRY AND PASTURE GRASSES DOMINATE
THE IMPACTED BUFFER AREA. BLACKBERRY WILL BE REMOVED, AND THE AREA WILL BE
SEEDED WITH A NATIVE GRASS MIX TO PRE -CONSTRUCTION CONDITIONS.
A STORMWATER DISCHARGE PIPE AND OUTFALL STRUCTURE WILL BE LOCATED IN A
PORTION OF THE PRESCRIBED BUFFER OF PANTHER CREEK. THE PIPE WILL BE LAID BY
HAND ABOVE GROUND TO REDUCE POTENTIAL BUFFER IMPACT. THE INSTALLATION OF A
DISCHARGE STRUCTURE, AND INSTALLATION OF THE PIPE WILL RESULT IN 992 SQUARE FEET
OF TEMPORARY BUFFER IMPACT, AND 309 SQUARE FEET OF PERMANENT IMPACT. THIS AREA
IS DOMINATED BY INTACT FOREST, AND NO TRESS WILL BE AFFECTED DURING THE
CONSTRUCTION PROCESS. THE TEMPORARILY IMPACTED AREA WILL BE RESTORED WITH
NATIVE SHRUBS TO PRE -CONSTRUCTION CONDITIONS. TO MITIGATE FOR THE 309 SQUARE
FEET OF PERMANENT BUFFER IMPACT, ADDITIONAL BUFFER FOR PANTHER CREEK WILL BE
DESIGNATED AT A 1.5:1 RATIO. THIS ADDITIONAL BUFFER WILL RESULT IN NO NET LOSS OF
FUNCTIONS AND CONFORMS TO THE MITIGATION STANDARDS OUTLINED BY RMC CHAPTER
4.3.050.

PLAN GOALS, OBJECTIVES, AND PERFORMANCE STANDARDS ARE OUTLINED IN
TABLE 3-1 (BELOW). THE GOALS AND OBJECTIVES OF THIS PLAN ARE CONSIDERED
ACHIEVED WHEN THE PERFORMANCE STANDARDS ARE SATISFIED.
AS -BUILT
FOLLOWING COMPLETION OF THE WORK SHOWN ON THIS PLAN, A QUALIFIED
PROFESSIONAL SHALL PREPARE AN AS -BUILT OF THE COMPLETED WORK. THE
AS -BUILT SHALL SUMMARIZE THE COMPLETED WORK AND ANY DEVIATIONS FROM
THE APPROVED VERSION OF THIS PLAN. IN ADDITION, THE AS -BUILT SHALL
CONTAIN BASELINE MONITORING DATA AND PHOTOGRAPHS OF EACH
ENHANCEMENT AREA. FOLLOWING PLANT INSTALLATION, PERMANENT
COMPLIANCE MONITORING PLOTS OR TRANSECTS SHALL BE ESTABLISHED TO
DOCUMENT BASELINE VEGETATION CHARACTERISTICS WITHIN EACH ENHANCEMENT
AREA. COMPLIANCE MONITORING PLOTS AND TRANSECTS SHALL BE SCALED
APPROPRIATELY TO ACCURATELY SAMPLE THE FOLLOWING:
® NATIVE WOODY PLANT SPECIES (TREES AND SHRUBS); AND
NOXIOUS WEED SPECIES.
BASELINE COMPLIANCE MONITORING DATA SHALL BE COLLECTED AT THE TIME OF
THE AS -BUILT USING THE ESTABLISHED SAMPLE PLOTS OR TRANSECTS (SEE
"ANNUAL COMPLIANCE MONITORING" FOR FIELD DATA COLLECTION
REQUIREMENTS).
PERMANENT PHOTO POINTS SHALL BE ESTABLISHED TO PHOTOGRAPHICALLY
DOCUMENT REPRESENTATIVE CONDITIONS WITHIN EACH ENHANCEMENT AREA.
BASELINE PHOTOGRAPHS SHALL BE TAKEN AT THE TIME OF THE AS -BUILT.
THE AS -BUILT AND BASELINE MONITORING DATA SHALL BE SUBMITTED TO THE CITY
OF RENTON NO LATER THAN 30 DAYS FROM THE DATE THAT THE WORK SHOWN ON
THIS PLAN HAS BEEN COMPLETED.

FOLLOWING ACCEPTANCE OF THE AS -BUILT BY THE CITY OF RENTON, ANNUAL
COMPLIANCE MONITORING SHALL BE COMPLETED FOR A PERIOD OF FIVE (5) YEARS.
ANNUAL COMPLIANCE MONITORING SHALL BE COMPLETED BY A QUALIFIED
PROFESSIONAL AND SHALL COMPRISE A SITE INVESTIGATION AND REPORTING PER
THE FOLLOWING INTERVAL:
• QUARTERLY DURING THE FIRST YEAR (YEAR 1) FOLLOWING PLANT
INSTALLATION; AND
• IN AUGUST OR SEPTEMBER OF THE SECOND THROUGH FIFTH YEARS
(YEAR 2 THROUGH YEAR 5) FOLLOWING INITIAL PLANT INSTALLATION.
MONITORING REPORTS SHALL BE SUBM11TED TO THE CITY OF RENTON NO LATER
THAN 30 DAYS FOLLOWING EACH MONITORING ASSESSMENT.
MONITORING SHALL COMPRISE A QUANTITATIVE ASSESSMENT OF CONDITIONS
WITHIN EACH ENHANCEMENT AREA FOR PURPOSES OF EVALUATING THE CURRENT
YEAR'S PERFORMANCE STANDARDS. AT THE TIME OF EACH MONITORING
ASSESSMENT, THE FOLLOWING INFORMATION SHALL BE COLLECT ED WITHIN EACH
ENHANCEMENT AREA AND ASSESSED RELATIVE TO THE SUCCESS STANDARDS
ESTABLISHED FOR THE PROJECT:
• THE CONDITION OF INSTALLED PLANT STOCK INCLUDING SURVIVORSHIP,
HEALTH, AND VIGOR. THE RATIONALE FOR POOR CONDITIONS, IF PRESENT,
WILL BE DETERMINED.
. THE SPECIES COM POSITION OF AND AREAL COVERAGE PROVIDED BY
NATIVE WOODY PLANT SPECIES (TREES AND SHRUBS).
• THE SPECIES COMPOSITION OF AND AREAL COVERAGE PROVIDED BY
NOXIOUS WEED SPECIES.
A DIRECT COUNT INVENTORY AND ASSESSMENT OF ALL INSTALLED PLANT STOCK
SHALL BE USED TO EVALUATE PLANT STOCK CONDITIONS. SPECIES COMPOSITION
AND AREAL COVERAGE SHALL BE ASSESSED USING THE SAMPLE PLOTS OR
TRANSECTS ESTABLISHED DURING THE AS -BUILT.
IN ADDITION TO A QUANTITATIVE ASSESSMENT OF CONDITIONS WITHIN EACH
ENHANCEMENT AREA, PHOTOGRAPHS SHALL BE TAKEN FROM THE PERMANENT
