JAN 2 2 2DD7 BUILDINGD\1/ISION Project Manager: HM Designed: MG Drafted: MG Checked: HM File name: WETLAND SP2.DWG JOB NUMBER: 060920 SHEET NUMBER: 40F5 Executive Summary This plan seeks to re-establish wetland conditions adjacent to an existing wetland in the Panther Creek drainage basin of Renton, Washington. Existing conditions include a sparsely-vegetated fill pad across most of the property. A detention pond (Raedeke Associates 2006) is found just east of this pad with an existing wetland located east of the pond. The existing wetland also bends around the northern edge of the fill pad and this is where wetland impacts are proposed. Large shrubs (willow) dominate most of the existing wetland with a few trees including Pacific willow and black cottonwood. The portion of wetland to be filled is dominated by weedy emergent vegetation with some floating-leaved aquatic plants. Willows and cottonwood saplings are found at the margins of this portion of the wetland. East of the existing wetland is the fill slope for SR 167. The highway bisects the existing wetland from extensive wetlands to the east, also associated with Panther Creek. The existing wetland extends north and south along SR 167 for a significant distance. Prior to original development, the area beneath the fill pad and the detention pond was wetland. By adjusting grades in the detention pond, improving soil conditions and installing vegetation appropriate to the ecoregion, wetland conditions will be reestablished. This plan will improve overall wetland function over the present condition. The wetland area to be filled is currently of low function with only a very narrow line of trees for a buffer on its north and a very degraded buffer to the west and south. Water quality will be improved by expanding overall wetland size, providing a more dense assemblage of vegetation, adding more emergent plants in the new wetland and vegetating the western buffers. Flooding and erosion functions will be improved by expanding the wetland size. Habitat functions will be improved by improving the density and variety of native vegetation in the wetland and buffer and by providing habitat features in the form oflarge and small woody debris. Wetland impact and compensation Action Area (ft2) --~-- Existing wetland to be preserved: 4,597 Existing wetland loss (fill): 2,158 Wetland to be reestablished: 4,420 Wetland buffer to be planted: 5,843 -----r-~·-~-- Total functioning habitat replaced: 10,263 Wetland compensation to loss ratio: 2:1 Overall compensation to loss ratio: 4.8: 1 Goals 1) Reestablish wetland conditions adjacent to the existing wetland boundary. 2) Establish a functioning wetland buffer. 3) Establish native vegetation in the wetland and buffer appropriate to the ecoregion. a. Establish shrub and sapling vegetation in the buffer and outer wetland perimeter. b. Establish emergent and floating-leaved aquatic vegetation in the wetland interior. 4) Improve wildlife habitat. Performance Standards The standards listed below shall be used to judge the success of the plan over time. If performance standards are met at the end of year 5, the site will then be deemed successful and the performance security bond will be eligible for release by City of Renton. 1. Survival: Achieve 100% survival of installed plants by the end of year 1. This standard can be met through plant establishment or through replanting as necessary to achieve the required numbers. 2. Native cover in woody vegetation areas: • Achieve 60% cover of native trees and shrubs by year 3. Volunteer species may count towards this cover standard. • Achieve 80% cover of native trees and shrubs by year 5. Volunteer species may count towards this cover standard. 3. Native cover within emergent areas: • Achieve 80% cover of native emergent plants by year 3. Volunteer species may count towards this cover standard. • Achieve 100% cover of native emergent plants by year 5. Volunteer species may count towards this cover standard. 4. Species diversity: • Establish at least 3 native tree species, 5 native shrub species and I native groundcover species by year 5. Volunteer species may count towards this standard. • Establish at least 3 native emergent/floating aquatic species by year 5. Volunteer species may count towards this cover standard. 5. Invasive cover: • No more than 10% cover by invasive weed species. Reed canarygrass is excluded from this standard. • Planted areas will be maintained free of reed canary grass "monoculture areas." A monoculture area is defined as a 50 square-foot patch of 100% reed canarygrass that is entirely absent of healthy native trees or shrubs. Patches are not linear or long and narrow ( e.g. 2 feet wide and 25 feet long). Rather, patches are roughly square, circular, or otherwise simply shaped polygons. Monitoring Methods This monitoring program is designed to track the success of the mitigation site over time and to measure the degree to which it is meeting the performance standards outlined elsewhere in this document. An as-built plan will be prepared prior to the beginning of the monitoring period. The as-built plan shall be a mark-up of the planting plans included in this plan set. The as-built plan will document any departures in plant placement or other components from the proposed plan. Transects During the as-built inspection, the monitoring biologist shall install monitoring transects. Approximate transect locations shall be marked on the as-built plan. Seven 25-foot transects shall be established in the planted areas: three in the buffer, two in the woody vegetation area of the wetland and two in the emergent area of the wetland. All other planted areas not directly covered by transects will be visually assessed and noted as to how they are meeting the performance standards. w u z w :::) (Y w V') ~ 0::: ~ Monitoring should take place twice annually for five years. During each year there shall be a spring and a late summer or fall visit. First-year monitoring should commence in the first spring subsequent to installation. The spring monitoring visit will record maintenance needs such as plant replacement and weeding needs. Following the spring visit the biologist will notify the owner and/or maintenance crews of necessary early growing season maintenance. The second annual monitoring visit will contain the bulk of the site assessment and will take place in the late summer or early fall. The late-season formal monitoring visit shall record and report the following in an annual report submitted to the City of Renton. 1. General summary of the spring visit. 2. First-year counts of dead plants by species in the planted areas. 3. Counts of dead plants where mortality is significant in any monitoring year. 4. Estimate of native tree and shrub cover using the line intercept method along established transects in woody vegetation planted areas. 5. Estimate of native emergent cover using the visual estimation of cover class method along established transects in emergent vegetation planted areas. 6. Estimate of non-native, invasive weed cover using the line intercept method along established transects in woody vegetation areas. . , 7. In all planted areas reed canarygrass "monoculture areas" will also be uoted and field mapped. A monoculture area is defined as a 50 square-foot patch of 100% reed canarygrass that is entirely absent of healthy native trees or shrubs. Patches are not linear or long and narrow (e.g. 2 feet wide and 25feet long). Rather, patches are roughly square, circular, or otherwise simply shaped polygons. 8. Notes or sketches of non-native weed problems in planted areas outside of transects. 9. Photographic documentation from fixed reference points or transect ends. l 0. Intrusions into the planting areas, vandalism or other actions that impair the intended functions of the planted areas. 11. Recommendations for maintenance or repair of any portion of the mitigation area. Construction Notes and Specifications Work Sequence Note: specifications for items in bold can be found below under "Material Specifications and Defmitions." Note: The Watershed Company [(425) 822-5242] personnel, or other persons qualified to evaluate environmental restoration projects, shall monitor: I) All site preparation •Clearing • Final grading • Woody debris placement 2) Plant material inspection • 50% plant installation inspection • 1 OOo/o plant installation inspection General Work Sequence 1) Mechanically, remove all Himalayan blackberry vines and vine roots from the entire area outside the graded portion using the following methodology: , a. Avoiding damage to existing woody vegetation to remain and at the direction of the biologist, clear vine thickets and individual vines and dispose of off-site. b. Hand rake out remaining roots as necessary in areas loosened by mechanical removal. c. Where vines are close to existing vegetation to remain, cut away vines and dig and rake out roots by hand. 2) Note: Large parts of the graded area floods during the wet weather season. Therefore, grading is to take place only between May 15 and September 15. 3) Grade the wetland and buffer areas as shown on the grading plan. Save all woody material 2 inches in diameter and larger for later placement. 4) Over-excavate wetland and buffer area to a depth of 18 inches below design grade. 5) Import topsoil in the wetland to a depth of 18 inches in the wetland and 18 inches in the buffer. 6) Place woody debris and saved woody material as shown on the plans or a~ directed by the biologist. 7) All plant installation is to take place during the dormant season (October 15th -March 1st), for best survival. 8) Prepare a planting pit for each plant and install per the planting details. 9) Mulch each plant with a circular wood chip mulch ring (15 yards needed), four inches thick and extending to a distance of9 inches from the plant stem (18 inches in diameter). , 10) Hydroseed indicated areas with the seed mix on the planting legend. Do not seed over mulch rings. 11) Install sensitive area signs along the chain link fence. . Material Specifications and Definitions Wood chip mulch: "Arborist chips" (chipped woody material) approximately 1 to 3 inches in maximum dimension (not sawdust or coarse hog fuel). This material is commonly available in large quantities from arborists or tree-pruning companies. This material is sold as "Animal Friendly Hog Fuel" at Pacific Topsoils [(800) 884-7645]. Wood chips may also be generated on-site by chipping woody material cleared as necessary for construction of the proposed improvements. Mulch shall not contain appreciable quantities of garbage, plastic, metal, soil, and dimensional lumber or construction/demolition debris. Quantity required: 15 cubic yards. Fertilizer: Slow release, granular fertilizer such as OsmocoteTM or equal product. Most retail nurseries carry this product. Follow manufacturer's instructions for application. Keep fertilizer in a weather-tight container while on site. Note that fertilizer is to be applied only in years two, three, four and five and not in the first year. Woody Debris: Salvaged from site clearing or imported. At least 5 pieces, three.must be trees with roots intact, minimum length: 18 feet long. Two pieces must be root-wads with a minimum root spread of 5 feet. At least 3 pieces shall be from coniferous trees. Material to be inspected and approved by biologist prior to placement. Topsoil: 2-way topsoil mix from Cedar Grove Topsoil or equivalent. Quantity required: 324 cubic yards (buffer)+ 442 cubic yards (wetland)= 766 cubic yards. Biologist: Watershed Company [( 425) 822-5242] personnel, or other persons qualified to evaluate environmental restoration projects. Maintenance The site will be maintained for five years following completion of the construction. Note: specifications for items in bold can be found above under "Material Specifications and Definitions." 1) Replace each plant found dead in the summer monitoring visits during the upcoming fall dormant season (October 15th to March 1st). 2) Follow the recommendations noted in the spring monitoring site visit. 3) Himalayan blackberry maintenance plan (within planted areas only): a. Twice yearly, re-sprouting and emerging blackberry shoots are to be treated with herbicide. This treatment is to continue each summer until blackberry shoots are no longer present in the mitigation area or until the project is accepted as complete at the end of the monitoring/maintenance period. Follow the instruction outlined in b., below. b. During the growing season only, apply herbicide to any re-sprouting blackberry shoots emerging from the removal areas. Herbicide treatment is to be conducted only by licensed applicators. c. Once per year, vines and thickets encroaching from outside of the planted area are to be cut back to at least 10 feet from the planted area. 4) Reed canarygrass maintenance plan (within planted areas only): d. Remove reed canarygrass and roots from the base of all installed plants and desirable volunteer vegetation to a distance of 18 inches from the main plant stem. If weeding is difficult due to a thick sod layer, herbicide may be used if approved by City of Renton. Areas around desirable plants shall be treated with herbicide only by a state licensed applicator. Glyphosate without a surfactant (Rodeo) is approved for use in aquatic areas. e. Identify reed canarygrass monoculture areas defined as a 50 square-foot patch of 100% reed canarygrass that is entirely absent of healthy native trees or shrubs. Patches are not linear or long and narrow ( e.g. 2 feet wide and 25 feet long). Rather, patches are roughly square, circular, or otherwise simply shaped polygons. f.Install trees and shrubs in monoculture areas during the dormant season. Species selection shall be based on plants shown on this plan or as directed by the biologist. 5) General weeding for all planted areas: g. At least twice-yearly, remove all competing weeds and weed roots from beneath each installed plant and any desirable volunteer vegetation to a distance of 18 inches from the main plant stem. Weeding should occur at least twice during the spring and summer. Frequent weeding will result in lower mortality and lower plant replacement costs. h. More frequent weeding may be necessary depending on weed conditions that development after plan installation. i. Do not weed the area near the plant bases with string trimmer (weed whacker/weed eater). Native plants are easily damaged or killed, and weeds easily recover after trimming. 6) Apply slow release granular fertilizer to each installed plant annually in the spring (by June l) of years two through five. Do not fertilize plants when inundated or submerged. 7) Mulch the weeded areas beneath each plan with wood chips as necessary to maintain a 4-inch thick mulch ring and keep down weeds.

EROSION AND sgDIMENT CONTROL NOTES 1. Approval of this erosion and sedimentation control (ESC) pion does not constitute an approval of permanent road or drainage design (e.g., size and location of roads pipes, restrictors, channels, retention facilitiEis, utilities, etc.). 2. The Implementation of these ESC plans and the construction, maintenance, replacement, and upgrading of thi,se ESC facilities is the responsibility of the opplicant/ESC supervisor until all construction Is i)pproved. 3. The baundar[es of the clearing limits shown on this pion shall be clearly flagged by a continous length of survey' tape (or fencing, if required) prior to construction. During the constructionperiod, no disturbance beyond the clearing limits shall be permitted. The clearing limits shall be maintained by the appllcant/ESC supervisor for the duration of construction. 4. The ESC facilities shown on this plan must be constructed prior to or in conjunction with all clearing and so ;qs ,to ensure that the transport of sediment to surface waters , drainage systems, and adjacent properties is minimized. 5. The ESC fadt!t.ies shown on this plan are the minimum requirements for anticipated site conditions. Duririy _t,he.,.sonstruction period, these ESC faciHties shall be upgladed as needed for unexpected st(?r;C-i events and modified to account for changing site conditions (e.g., additional sump p~tnps;'\eibcation of ditches and silt fences, etc.). ,. . ' 6. The,J:SC fa0!Jities shall be inspected daily by the applicant/ESC supervisor and maintained to ens\!;:evcontlnued proper functioning. Written records shall be kept of weekly reviews of the ESC , //acilities during te wet season (Oct. 1 to April 30) and of monthly reviews during the dry season cc (May 1 to Sept. ;30). · I . 7. Any areas of exposed soils, including roadway embankments, that will not be disturbed for two days during the 'wet season or seven days during the dry season shall be immediately stabilized with the approved Esp methods (e.g. seeding, mulching, plastic covering, etc.). 8. Any area ne~ding ESC measures that do not require immediate attention shall be addressed within fifteen (15) days. 9. The ESC facilities on inactive sites shall be inspected and maintained a minimum of once a month or within ,forty eight ( 48) hours fallowing a storm event. 10. At no time· shall more than one (1) foot of sediment be allowed to accumulate within a catch basin. All catch basins and conveyance lines shall be cleaned prior to paving. The cleaning operation shall n_ot flush sediment-laden water into the downstream system. 11. Stabilized construction entrances and roads shall be installed at the beginning of construction and .maintained for the duration of the project. Additional measures, such as wash pads, may be required to ensu,e that all paved areas are kept clean for the duration of the project. 12. Any perman~nt flow control facility used as a temporary settling basin shall be modified with the necessary erpsion control measures and shall provide adequate storage capacity. If the facility is to function ul\imately as an infiltration system, the temporary facility must be graded so that the bottom and sides are at least three feet above the final grade of the permanent facility. 13. Where straw mulch for temporary erosion control is required, it shall be applied at a minimum thickness of 2 tu 3 inches. 14. Prior to the beginning of the wet season (Oct.1), all disturbed areas shall be reviewed to identify which ones can be seeded in preparation for winter rains. Disturbed areas shall be seeded within one week of the beginning of the wet season. A sketch map of those areas to be seeded and those areas to remain uncovered shall be submitted to the DOES inspector. The DOES inspector can require seeding of additional areaas in order to protect surface waters, adjacent properties, or drainage facilities. CITY OF RENTON RYKELS ENGINEERING GROUP, INC.
