CORPS OF ENGINEERS _ P.O. BOX 3755 SEATTLE, WASHINGTON 98124 ,:255 REPLY TO ATTENTION OF Regulatory Branch APR 2 3 1998 Scott Woodbury, P.E. City of Renton, Surface Water Utility 200 Mill Avenue South Renton, Washington 98055 Reference : 97-4-02243 Renton, City of Dear Mr. Woodbury: Your December 17, 1997, Department of the Army permit application requested authorization for several construction activities associated with the Southwest 23rd Street channel which is a tributary of Springbrook Creek in the city of Renton, Washington. The construction activities include replacing 18-inch culverts with a pre-cast concrete box culvert; removal of a beaver dam and other debris; removal of accumulated vegetation along the channel; replacing a non-functioning 30-inch culvert with a new culvert; and removal of sediment from twin culverts under Lind Avenue to maintain drainage. We have reviewed all of the proposed activities . The removal of the beaver dam, loose debris, and the accumulated vegetation which is to be cut just above the ground surface does not require authorization by the Corps of Engineers . In the event that these materials are dredged or removed in some manner that would result in a discharge of soil, Department of the Army authorization would be required under Section 404 of the Clean Water Act . As described in your permit application, the remaining work constitutes routine maintenance or replacement of existing structures . Nationwide Permit 3 (33 CFR Part 330, Appendix A, paragraph B (3) ) , authorizes the repair, rehabilitation, or replacement of existing structures . Enclosed is the full text of Nationwide Permit 3 and the conditions that apply to it . Your work is authorized by Nationwide Permit 3 provided you comply with the terms of the nationwide permit and the conditions . Read them carefully. You must comply with all of the conditions and requirements . -2- If your work meets all of the above criteria for authorization by Nationwide Permit 3 , then you need no further permission from us . You must still comply with other State and local requirements which pertain to the work. This verification will be valid for a period of 2 years from the date of this letter or until the nationwide permit is modified, reissued, or revoked. If you have any questions, please contact me at telephone (206) 764-6906 . Sincerely, James D. Green, Project Manager Application Review Section Enclosures NATIONWIDE PERMIT/CORPS SEATTLE DISTRICT/22 FEBRUARY 1997 3. MAINTENANCE. The repair, rehabilitation, or replacement of any previously authorized, currently serviceable, structure or fill, or of any currently serviceable structure or fill authorized by 33 CFR 330.3, provided that the structure or fill is not to be put to uses differing from those uses specified or contemplated for it in the original permit or the most recently authorized modification. Minor deviations in the structure's configuration or filled area including those due to changes in materials, construction techniques, or current construction codes or safety standards which are necessary to make repair, rehabilitation, or replacement are permitted, provided the environmental effects resulting from such repair, rehabilitation, or replacement are minimal. Currently serviceable means useable as is or with some maintenance, but not so degraded as to essentially require reconstruction. This NWP authorizes the repair, rehabilitation, or replacement of those structures destroyed by storms, floods, fire or other discrete events, provided the repair, rehabilitation, or replacement is commenced or under contract to commence within two years of the date of their destruction or damage. In cases of catastrophic events, such as hurricanes or tornadoes, this two-year limit may be waived by the District Engineer, provided the permittee can demonstrate funding, contract, or other similar delays. Maintenance dredging and beach restoration are not authorized by this NWP. (Sections 10 and 404) Notification Requirement -- None. Regional Conditions -- None. EPA and Puyallup Tribe 401 Certification -- Denied without prejudice. An individual 401 Certification is required for all Section 404 activities. State 401 Certification -- Partially denied without prejudice. An individual certification is required for projects authorized under this NWP involving the extension, replacement, repair, or increase in capacity of a domestic wastewater outfall in marine waters that do not meet the conditions of Inter-Agency Permit Streamlining Document: Shellfish and Domestic Wastewater Discharge Outfall Proiects (October 10, 1995) issued by the Washington Departments of Ecology, Fish and Wildlife, Health, and Natural Resources. CZM Consistency Response -- Partially denied without prejudice subject to the 401 Certification conditions. An individual CZM Consistency Response must be obtained for projects requiring individual 401 Certification and located within counties in the coastal zone. EXCERPT FROM CORPS OF ENGINEERS' SPECIAL PUBLIC NOTICE DATED MARCH 5 , 1997 NATIONAL CONDITIONS FOR NATIONWIDE PERMITS The following general conditions must be followed in order for any authorization by a NWP to be valid. GENERAL CONDITIONS : 1 . Navigation. No activity may cause more than a minimal adverse effect on navigation. 2 . Proper Maintenance. Any structure or fill authorized shall be properly maintained, including maintenance to ensure public safety. 3 . Erosion and Siltation Controls . Appropriate erosion and siltation controls must be used and maintained in effective operating condition during construction, and all exposed soil and other fills , as well as any work below the ordinary high water mark or high tide line, must be permanently stabilized at the earliest practicable date. 4 . Aquatic Life Movements . No activity may substantially disrupt the movement of those species of aquatic life indigenous to the waterbody, including those species which normally migrate through the area, unless the activity' s primary purpose is to impound water. 5 . Equipment . Heavy equipment working in wetlands must be placed on mats, or other measures must be taken to minimize soil disturbance . 6 . Regional and Case-By-Case Conditions . The activity must comply with any regional conditions which may have been added by the Division Engineer (see 33 CFR 330 . 4 (e) ) and with any case specific conditions added by the Corps [Seattle District] or by the state or tribe in its Section 401 water quality certification. 7 . Wild and Scenic Rivers . No activity may occur in a component of the National Wild and Scenic River System; or in a river officially designated by Congress as a "study river" for possible inclusion in the system, while the river is in an official study status ; unless the appropriate Federal agency, with direct management responsibility for such river, has determined in writing that the proposed activity will not adversely effect the Wild and Scenic River designation, or study status . Information on Wild and Scenic Rivers may be obtained from to appropriate Federal land management agency in the area (e .g . , National Park Service, U. S . Forest Service, Bureau of Land Management , U. S . Fish and Wildlife Service . ) 8 . _Tribal Rights . No activity or its operation may impair reserved tribal rights, including, but not limited to, reserved water rights and treaty fishing and hunting rights . 9 . Water Quality Certification. In certain states, an individual Section 401 water quality certification must be obtained or waived (see 33 CFR 330 . 4 (c) ) . 10 . Coastal Zone Management . In certain states, an individual state coastal zone management consistency concurrence must be obtained or waived (see Section 330 . 4 (d) ) . 11 . Endangered Species . (a) No activity is authorized under any NWP which is likely to jeopardize the continued existence of a threatened or endangered species or a species proposed for such designation, as identified under the Federal Endangered Species Act, or which is likely to destroy or adversely modify the critical habitat of such species . Non-Federal permittees shall notify the District Engineer if any listed species or critical habitat might be affected or is in the vicinity of the project, and shall not begin work on the activity until notified by the District Engineer that the requirements of the Endangered Species Act have been satisfied and that the activity is authorized. (b) Authorization of an activity by a nationwide permit does not authorize the "take" of a threatened or endangered species as defined under the Federal Endangered Species Act . In the absence of separate authorization (e . g. , a Federal Endangered Species Act Section 10 Permit, a Biological Opinion with "incidental take" provisions, etc . ) from the U. S .

Subsequently, the permittee' s right to proceed under the NWP may be modified, suspended, or revoked only in accordance with the procedure set forth in 33 CFR 330 . 5 (d) (2) . (b) Contents of Notification: The notification must be in writing and include the following information : (1) Name, address, and telephone numbers of the prospective permittee; (2) Location of the proposed project; (3) Brief description of the proposed project ; the project ' s purpose; direct and indirect adverse environmental effects the project would cause; any other NWP (s) , regional general permits) or individual permit (s) used or intended to be used to authorize any part of the proposed project or any related activity; and (4) For NWPs 14 , 18 , 21, 26 , 29 , 34 , and 38 , the PCN must also include a delineation of affected special aquatic sites , including wetlands (see paragraph 13 . (f) ) ; 3 (5) For NWP 21, Surface Coal Mining Activities, the PCN must include an OSM [Department of the Interior, Office of Surface Mining] or State approved mitigation plan. (6)also include : For NWP 29, Single-Family Housing, the PCN must (i) Any past use of this NWP by the individual permittee and/or the permittee' s spouse; (ii) A statement that the single-family housing activity is for a personal residence of the permittee; (iii) A description of the entire parcel, including its size, and a delineation of wetlands . For the purpose of this NTAP, parcels of land measuring 0 . 5 'acre or less will not require a formal on-site delineation. However, the applicant shall provide an indication of where the wetlands are and the amount of wetlands that exists on the property. For parcels greater than 0 . 5 acre in size, a formal wetland delineation must be prepared in accordance with the current method required by the Corps . (See paragraph 13 . (f) ) ; (iv) A written description of all land (including, if available, legal descriptions) owned by the prospective permittee and/or the prospective permittee' s spouse, within a one mile radius of the parcel, in any form of ownership (including any land owned as a partner, corporation, joint tenant, cc-tenant, or as a tenant-by-the-entirety) and any land on which a purchase and sale agreement or other contract for sale or purchase has been executed; (7) For NWP 31, Maintenance of Existing Flood Control Projects, the prospective permittee must either notify the District Engineer with a Pre-Construction Notification (PCN) prior to each maintenance activity or submit a five year (or less) maintenance plan.

A letter may also be used. [NOTE: The Seattle District Corps also accepts the completed Joint Aquatic Resource Permit Application (DARPA) form as notification. ] (d) District Engineer' s Decision: In reviewing the pre-construction notification for the proposed activity, the District Engineer will determine whether the activity authorized by the NWP will result in more than minimal individual or cumulative adverse environmental effects or may be contrary to the public interest . The prospective permittee may, optionally, submit a proposed mitigation plan with the pre-construction notification to expedite the process and the District Engineer will consider any optional mitigation the applicant has included in the proposal in determining whether the net adverse environmental effects of the proposed work are minimal . If the District Engineer determines that the activity complies with the terms and conditions of the NWP and that the adverse effects are minimal, the District Engineer will notify the permittee and include any conditions the DE deems necessary. Any mitigation proposal must be approved by the District Engineer prior to commencing work. If. the prospective permittee elects to submit a mitigation plan, the District Engineer will exceditiously review the proposed mitigation plan, but will not commerce a second 30-day (or 45-day for NWP 26) notification crccedure . If the net adverse effects of the project (with the mitigation proposal) are determined by the District Engineer to be minimal , the District Engineer will provide a timely written response to the applicant stating that the project can proceed under the terms and conditions of the nationwide permit . If the District Engineer determines that the adverse effects of the proposed work are more than minimal, then he will notify the applicant either : (1) That the project does not qualify for authorization under the NWP and instruct the applicant on the procedures to seek authorization under an individual permit; 5 (2) That the project is authorized under the NWP subject to the applicant' s submitting a mitigation proposal that would reduce the adverse effects to the minimal level ; or (3 ) That the project is authorized under the NWp with specific modifications or conditions . (e) Agency Coordination: The District Engineer will consider any comments from Federal and State agencies concerning the proposed activity' s compliance with the terms and conditions of the NWPs and the need for mitigation to reduce the project ' s adverse environmental effects to a minimal level . (i) For NWP 14 , 21, 26 (between 1 and 3 acres of impact) , 29, 33 , 37, and 38 , the District Engineer will upon receipt of a notification, provide immediate) transmission, overnight mail or other s ma facsimile expeditious to the appropriate offices of the F • ous manner, e copy l State natural resource or water quality and Wildlife Service, Historic Preservation Officer (SHPO) , and, ify, EPA, State propri National Marine Fisheries Service . With the excceptiionate of,NWPe37, these agencies will then have 5 calendar days from the date the material is transmitted to telephone or fax the District Engineer notice that they intend to provide substantive, site-specific comments . If so contacted by an agency, the District Engineer will wait an additional 10 calendar days (16 calendar days for NWP 26 PCNs) before making a decision on the notification. The District Engineer will fully consider agency comments received within the specified time frame, but will provide no response to the resource agency. The District Engineer will indicate in the administrative record associated with each notification that the resource agencies' concerns were considered. Applicants are encouraged to provide the Corps multiple copies of notifications to expedite agency notification. [NOTE: The Corps Seattle District requests one copy. ] (ii) Optional Agency Coordination. For NWPs 5, 7, 12 , 13 , 17, 18 , 27, 31, and 34 , where a Regional Administrator of EPA, a Regional Director of USFWS, or a Regional Director of NMFS has formally requested general notification from the District Engineer for the activities covered by any of these NWPs, the Corps will provide the requesting agenc with notification particular NWPs . However, agencies cation ord o the not generally submitting substantive comments onvactive a ities of covered by any of these NWPs, the Corps district may discontinue providing notification to those regional agency offices . The District Engineer will coordinate with to identify which activities involving aPCNethato the eagenciesaenciewill provide substantive comments to the Corps . The District Engineer may also request comments from the agencies on a case by case basis when the District Engineer determines that such comments 6 would assist the Corps in reaching a decision whether effects are more than minimal either individually or cumulatively. (iii) Optional Agency Coordination, 401 Denial . For NWP 26 only, where the state has denied its 401 water quality certification for activities with less than 1 acre of wetland impact, the EPA regional administrator may request agency coordination of PCNs between 1/3 and 1 acre . The request may only include acreage limitations within the 1/3 to 1 acre range for which the state has denied water quality certification. In cases where the EPA has requested coordination of projects as described here, the Corps will forward the PCN to EPA only. The PCN will then be forwarded to the Fish and wildlife Service and the National Marine Fisheries Service by EPA under agreements among those agencies . Any agency receiving the PCN will be bound by the EPA timeframes for providing comments to the Corps . (f) Wetlands Delineations : Wetland delineations must be prepared in accordance with the current method required by the Corps . For NWP 29 see paragraph (b) (6) (iii) for parcels less than 0 . 5 acres in size . The permittee may ask the Corps to delineate the special aquatic site . There may be some delay if the Corps does the delineation. Furthermore, the 30-day period (45 days for NWP 26) will not start until the wetland delineation has been completed and submitted to the Corps, where appropriate . (g) Mitigation: Factors that the District Engineer will consider when determining the acceptability of appropriate and practicable mitigation include, but are not limited to : (i) To be practicable, the mitigation must be available and capable of being done considering costs, existing technology, and logistics in light of the overall project purposes; (ii) To the extent appropriate, permittees should consider mitigation banking and other forms of mitigation including contributions to wetland trust funds , "in lieu fees" to organizations such as The Nature Conservancy, state or county natural resource management agencies , where such fees contribute to the restoration, creation, replacement, enhancement, or preservation of wetlands . Furthermore, examples of mitigation that may be appropriate and practicable include but are not limited to : o Reducing the size of the project; o Establishing wetland or upland buffer zones to protect aquatic resource values ; and 7 O Replacing the loss of aquatic resource values by creating, restoring, and enhancing similar functions and values . In addition, mitigation must address wetland impacts, such as functions and values; and cannot be simply used to offset the acreage of wetland losses that would occur in order to meet the acreage limits of some of the NWPs wetlands cannot be created to change eag6-acre oss. for NWP2of wetlandsoto a 1 acre loss; however, 2 created acres can be used to reduce the impacts of a 3 -acre loss) . 14 . Compliance Certification. Every permittee who has received a Nationwide permit verification from the Corps will submit a signed certification regarding the completed work and any required mitigation. The certification will be forwarded by the Corps with the authorization letter and will include : a . A statement that the authorized work was done in accordance with the Corps authorization, including any general or specific conditions; b . A statement that any required mitigation was completed in accordance with the permit conditions; C . The signature of the permittee certifying the completion of the work and mitigation. IS . Multiple Use of Nationwide Permits . In any case where any NWP number 12 through 40 is combined with any other NWP number 12 through 40, as part of a single and complete project, the permittee must notify the District Engineer in accordance with paragraphs a, b, and c on the "Notification" General Condition number 13 . Any NWP number 1 through 11 may be combined with any other NWP without notification to the Corps, unless notification is otherwise required by the terms of the NWPs . As provided at 33 CFR 330 . 6 (c) two or more different NWPs can be combined to authorize a single and complete project . However, the same NWP cannot be used more than once for a single and complete project . NATIONAL CONDITIONS FOR NATIONWIDE PERMITS SECTION 404 ONLY CONDITIONS : In addition to the General Conditions, the following conditions apply only to activities that involve the discharge of dredged or 8 fill material into waters of the U. S . , and must be followed in order for authorization by the NWPs to be valid: 1 . Water Supply Intakes .

A suction dredge may be used with the intake hose operated by hand. This will ensure that impacts to existing tree and shrub vegetation already established along the banks of the channel are minimized, maintaining the existing shade canopy. • install willow and red-osier dogwood cuttings at 3-foot spacing along reaches of the channel from Springbrook Creek to East Valley Road where there currently is no existing shrub vegetation. • all twigs and debris removed from the channel will be bundled and placed along the channel as shown in the attached detail taken from the King County "Guidelines for Bank Stabilization Projects." The bundles will be staked near the ordinary high water. Attached is a copy of the notice that the Determination of Non-Significance for the SW 23rd Street Drainage Project is final.

Describe current use of the property, including structures: The primary land use within the project site is urban. Parcels surrounding the project site where the work will occur are developed as businesses or undeveloped pads. Wetland areas are present in many portions of the parcels that have not been filled (see Figure 2). Lind Avenue is a paved, public road. SW 23rd Street is a paved private access road (east of Lind Avenue) owned by Olympic Pipeline Company and a gated gravel access road owned by the City of Seattle west of Lind Avenue. The SW 23rd Street channel is located south of SW 23rd Street and flows east to west. It crosses under Lind Avenue in twin 9- by 14-foot corrugated metal pipe culverts and discharges into Springbrook Creek approximately 950 feet west of Lind Avenue. Petroleum pipelines owned by Olympic Pipeline Company cross the SW 23rd Street channel west of Lind Avenue in a north to south direction and are enclosed in an earthen berm. Undersized 18-inch culverts currently connect the SW 23rd Street channel at this pipeline crossing and are subject to frequent plugging with debris and sediment. A separate, smaller channel is located north of the private access roads in SW 23rd Street with an east to west direction. A 30-inch culvert crossing formerly conveyed flows under Lind Avenue to the west; however, the culvert was inadvertently plugged and the ditch west of Lind Avenue was filled in the mid 1980's from the development of the parcel west of Lind Avenue and north of SW 23rd Street. Water in the channel north of SW 23rd Street and east of Lind Avenue no longer has an outlet because of the plugged condition of the culvert under Lind Avenue. Lack of a defined ditch west of Lind Avenue and the steep fill slope from the adjacent parking lot prevent restoring the former drainage system. Is the property in agricultural land? No. 8. Proposed Activity: Include expected water quality and fish impacts, and proposed actions to reduce the duration and severity of those impacts and provide proper protection for fish life. 2 Purpose: The objectives of the proposed project are to: • restore drainage to the channel north of SW 23rd Street and correct flooding of the property north of the SW 23rd Street access road and east of Lind Avenue; • improve surface water conveyance from the SW 23rd Street channel into Springbrook Creek; • reduce maintenance problems associated with the undersized culvert under the Olympic Pipeline Crossing and increasing the flood protection to Lind Avenue, East Valley Road, and other tributary areas; • improve the potential for fish passage from Springbrook Creek to the SW 23rd Street channel, add habitat for fish that is currently not accessible, and provide off-channel habitat during high Springbrook Creek flows.. Proposed Activity: The proposed activity consists of the 5 elements described below. The project would occur in existing channels along SW 23rd Street near Lind Avenue (see Figure 3). (1) Replace the existing 18 inch culverts under the Olympic Pipeline crossing of the SW 23rd Street channel with a new, large pre-cast concrete box culvert. The Olympic Pipeline Company petroleum product lines are located west of Lind Avenue. The pipelines are located in an upland berm separating the pool at the downstream outlet of the twin 9- by 14-foot culverts from the SW 23rd Street Channel. The existing 18 inch culverts connecting these two wetland areas are currently undersized and cause high upstream water surface elevations, contributing to the flooding problems along East Valley Road. The culverts are also subject to frequent plugging, allowing sedimentation and vegetation debris to fill in and choke the upstream channel. The inside dimensions of the new box culvert will be 10 feet wide, 4 feet high and 80 feet long. The new box culvert is designed for the pipelines to remain in their existing location (see Figures 4 and 5). Invert elevation of the box culvert inlet would be 6.6 feet (NAVD) to tie into the existing SW 23rd Street channel; invert elevation of the outlet would be 6.5 feet (NAVD). A channel approximately 10 feet long with 1.5:1 side slopes would be excavated in the upland area to connect the box culvert outlet with the existing SW 23rd Street channel. The inlet and outlet of the box culvert would be rock-lined to maintain the structural integrity of the culvert to channel connection. The remaining portions of the 1.5:1 side slopes of the channel would be revegetated with native low growing wetland shrubs. (2) Remove the abandoned beaver dam at the mouth of the SW 23rd Street channel as it enters Springbrook Creek west of Lind Avenue and south of the SW 23rd Street access road and selectively remove debris and vegetation between Springbrook Creek and Lind Avenue. 3 The abandoned beaver dam would be removed to reduce debris accumulation and upstream sedimentation problems, reduce flood impacts, improve the potential passage of fish from Springbrook Creek into the SW 23rd Street Channel, and provide habitat during high Springbrook Creek flows. See Figure 3 for the location of the abandoned beaver dam. The beaver dam is approximately 6 feet wide and 16" inches high within the ordinary high water mark of the channel and consists of small, loose mix of willow twigs. Debris and shrub vegetation within and four feet above the level of the ordinary high water mark in the ditch between Springbrook Creek and Lind Avenue would be selectively removed. Hand held equipment would be used to cut vegetation above ground to avoid disturbance to the ground surface and minimize impacts to the overhanging shrub canopy outside of the clearing limits. Overhanging canopy from larger willows that does not obstruct channel flow would not be removed to maintain a shaded canopy over the channel. (3) Remove accumulated herbaceous and shrub vegetation along 1,180 linear feet of the SW 23rd Street channel from East Valley Road to Lind Avenue. Removal of the vegetation is a periodic maintenance activity that would be done to restore a defined flow channel and help maintain positive drainage. Approximately 8,000 square feet of vegetation within the wetland (channel and the channel's north bank) would be removed. Young shrub vegetation would be removed in the upland area and a narrow strip of wetland along the channel's north bank; emergent vegetation would be removed within the wetland in the channel. The existing SW 23rd Street channel along this reach is a V-shaped channel and varies in width from 10 to 25 feet at the elevation of the adjacent wetland area. Its depth below the ground surface of the wetland to the south, varies from approximately 2 to 5 feet. The surface of the adjacent private road is approximately 7 to 12 feet higher in elevation than the bottom of the channel. Vegetation removal along the south bank would be cut just above the ground surface. Reed canarygrass(Phalaris arundinacea), black cottonwood (Populus trichocarpa) saplings, and Himalayan blackberry (Rubus discolor) would be the dominant vegetation to be removed. Other wetland shrubs such as Douglas' spirea (Spiraea douglasii), red-osier dogwood (Corpus stolonifera), and willow (Salix sp.) would also be cut. Vegetation would be cut from the edge of the SW 23rd Street road surface, the upland portion of the banks, to the water surface. Because of the steep north channel bank (2:1), a narrow strip of shrub vegetation within the wetland area on the north channel bank would be cut (approximately 2 feet wide). In addition, in those areas where emergent vegetation is growing in the channel, the above ground portion of the vegetation would be removed by scraping the vegetation at the ground surface from the channel with a backhoe. No widening or deepening of the channel or soil disturbance is intended from this maintenance activity. The backhoe would operate from the SW 23rd Street access road. 4 (4) Install a new 24-inch culvert parallel to and east of Lind Avenue to connect a small channel north of the SW 23rd Street access road to the SW 23rd Street channel, south of the access road to restore drainage system function. Because of the existing non-functioning 30-inch culvert that crosses Lind Avenue north of the SW 23rd Street channel, a new culvert would be installed to route flow from the small channel located north of SW 23rd Street and east of Lind Avenue to the SW 23rd Street channel. Development of the property north of the channel and west of Lind Avenue plugged the existing culvert approximately 10 years ago. Because this channel currently has no drainage outlet along Lind Avenue or SW 23rd Street, surface water no longer drains but collects in the channel and has created wetland conditions and flooding problems on the property north of SW 23rd Street and east of Lind Avenue. Installation of a new culvert would maintain the drainage system that was in place before the culvert was plugged. The new culvert would be a 24-inch diameter culvert with the inlet located just east of the existing 30-inch non-functioning culvert's inlet. The invert elevation of the north end of the new culvert, 12.0 feet (NAVD), is equal to the existing non-functioning culvert. The invert elevation of the south end of the new culvert would be 8.2 feet (NAVD), which is approximately 1.7 feet higher than the invert elevation of the existing 9-foot by 14-foot culverts under Lind Avenue south of SW 23rd Street. Riprap would be placed at the culvert's outlet to dissipate stormwater runoff entering into the SW 23rd Street channel. See Figures 6 and 7 for the plan and profile alignment design of the new culvert. (5) Remove sediment from the twin 9-foot by 14-foot culverts under Lind Avenue at SW 23rd Street and immediately upstream and downstream of the culvert openings. This activity is part of the periodic maintenance required to maintain the positive drainage along this portion of the SW 23rd Street channel. Approximately 2 to 3 feet of sediment has accumulated in the SW 23rd Street channel and at both openings of the twin culverts. A backhoe and/or vacuum truck positioned on the SW 23rd Street access road would remove this sediment to the invert elevation of the culverts. The sediment removal would occur within approximately 20 feet of the culvert opening on the east side of Lind Avenue, and within the pool area on the west side of Lind Avenue. Sediment would be disposed on an upland site. (Sediment within the culverts would be removed using a combination of human assisted shoveling and a vacuum device to bring the sediment to a truck/storage container on the access road.) Impacts on Project Elements 1-5: Cumulative impacts on wetlands from the proposed flood control maintenance activities are as follows: • permanent fill from placement of the new culverts or riprap at the outlets of the culverts would be approximately 300 square feet (the majority of the riprap fill would occur in areas where rock-lined channel banks or unvegetated channel bottoms exist); 5 • temporary disturbance from the construction related activities to place the new culverts would be approximately 250 square feet(temporary disturbance occurs primarily on rock- lined banks and unvegetated channel bottoms); and 9 temporary disturbance from the removal of accumulated sediment at the inlet and outlet of the twin culverts would be 1,400 square feet (to a depth of approximately 2.5 feet would equal 130 cubic yards). The total impacts on wetlands from improvements to the culvert drainage system would be approximately 1,950 square feet (0.04 acre). In addition, vegetation maintenance along the SW 23rd Street channel would temporarily remove approximately 8,000 square feet of young shrub and herbaceous plants from the channel banks and bottom. Specific impacts from each of the five project elements are discussed below. Mitigation measures taken to reduce impacts are presented in the attached wetland report prepared for this application. (1) Replace the existing 18 inch culverts under the Olympic Pipeline crossing of the SW 23rd Street channel with a new pre-cast concrete box culvert . Impacts from the culvert replacement will occur from the construction of the box culvert's inlet structure within a small portion of the wetland and from construction of the channel connecting the new box culvert to the existing SW 23rd Street channel (see Figure 4). Temporary construction impacts and the installation of the new box culvert are expected to be limited to a cumulative area of approximately 350 square feet of wetland. Downstream sedimentation issues will be minimized by routing any channel flow that may occur during construction in a bypass pipe. The area where work will occur will be protected from the rest of the channel by sedimentation fences. Work would be scheduled to occur outside of the wet season during low flows. Wetland area that will be impacted is primarily rock lined slopes where the new box culvert's inlet and outlet occur. At the outlet, scrub-shrub vegetation (willow and red-osier dogwood) is growing at and above the wetland boundary (approximately the ordinary high water line). Several willow and/or red-osier dogwood plants would likely be removed for placement of the new box culvert. The new channel slopes that are to be constructed connecting the box culvert to the existing SW 23rd street channel would be revegetated with native low growing shrubs to compensate for the vegetation removed to construct the channel. Approximately 200 square feet of wetland and channel bottom would be created from construction of the new channel. No impacts to fish are expected to occur. Fish have not been observed in the channel and current use would be limited by the downstream beaver dam. The proposed project replaces culverts that are a barrier to fish with a fish passable culvert. 6 Downstream water quality would be protected during construction by placement of sedimentation fences and rerouting surface flows back into the channel downstream of the construction area via a bypass pipe. A series of straw bales would be placed in the channel to contain sediment from the water in the bypass pipe. The bales would be removed after all construction is complete. Sediment would be removed if large enough quantities accumulated behind the bales. Temporary dewatering of the culvert construction area to allow for construction of the box culvert and other project elements could result in pumping of turbid water through the bypass system and into the SW 23rd Street channel. The straw bales in the channel would trap any sediment before reaching Springbrook Creek. Existing water elevations in Wetland W-8N during storm events are caused by the undersized culverts under the Olympic Pipeline crossing. Hydraulic modeling of surface water elevations within the SW 23rd Street channel indicate that the surface water elevations for a 2 year storm would be reduced by 2 feet by the culvert replacement. This is not expected to impact wetland acreage associated with wetland W-8N because (1) surface water connections between the channel and wetland W-8N would still occur and surface water would continue to inundate wetland W-8N, (2) base flow within the channel is not expected to change, and (3)two-year storm overflows into the wetland are relatively short in duration (less than one day) according to hydrologic/hydraulic simulation. The decrease in the maximum water levels during storm events is not expected to significantly change the wetland vegetation. Some herbaceous species may decrease (e.g., cattail and yellow flag)whereas other species may increase(e.g., sedges and rushes). Willow and spirea are species adapted to water level fluctuations and are expected to continue to dominate the wetland. (2) Remove the abandoned beaver dam at the mouth of the SW 23rd Street channel as it enters Springbrook Creek west of Lind Avenue and south of the SW 23rd Street access road and selectively remove debris and vegetation between Springbrook Creek and Lind Avenue. Removal of the small beaver dam which has deteriorated to a loose assemblage of sticks will not require any removal of wetland vegetation. No impacts on the channel or associated wetland are expected to occur. The beaver dam can be removed with hand held tools and equipment to avoid the disturbance of surrounding vegetation. Because the dam is loosely held together, base flow within the channel is not expected to change significantly to affect the surrounding wetland. High groundwater and surface flows associated with winter and spring storm events will continue to supply a source of water to support the scrub-shrub and forested wetland W-1ON. Removal of debris and vegetation along the channel between Springbrook Creek and Lind Avenue would be done by selectively cutting lower growing vegetation hanging into the channel that obstructs flow. This activity would not directly impact the wetland or channel because only above ground material would be removed. The ground surface and soils would not be disturbed by the activity. Overhanging canopy from larger willows that does not obstruct channel flows would not be removed to maintain a shaded canopy over the channel. 7 (3) Remove accumulated herbaceous and shrub vegetation along 1,180 linear feet of the SW 23rd Street channel from East Valley Road to Lind Avenue. Vegetation will be cleared along the south bank of the channel and within the channel. Vegetation will be cleared by mowing and scraping and would not affect the topography of the wetland. Although the removal of vegetation would result in the loss of some wildlife habitat, the amount lost is incremental relative to the amount of surrounding scrub-shrub habitat in wetlands W-8N,W-7S, and W-10N. Fish passage in the channel will be improved and this reach will be restored as off-channel habitat for Springbrook Creek after the Olympic Pipeline culvert is replaced (see Element 1). Emergent vegetation to be removed from the channel include common cattail (Typha latifolia), American brooklime (Veronica americana), reed canarygrass, and yellow flag (Iris pseudacorus). (4) Install a new 24-inch culvert parallel to and east of Lind Avenue to connect a small channel north of the SW 23rd Street access road to the SW 23rd Street channel, south of the access road to restore drainage system function. Impacts associated with installation of the new culvert would occur from placement of the culvert's outlet into the SW 23rd Street channel. Approximately 100 square feet of wetland W-8N would be disturbed where the culvert daylights into the wetland's channel bank; approximately 100 square feet of wetland W-7S would be temporarily disturbed by construction activities to install the culvert at the inlet. Restoring the drainage system function would return the hydrology in the channel on the north side of the private access road and wetland W-7S to conditions that existed before the existing culvert was plugged. Re-establishing the drainage from wetland W-7S to wetland W-8N could result in the potential loss of approximately 0.5 acre of wetland hydrology in the 1.75 acre wetland W-7S. Lowering of surface water elevations in the channel portion of the wetland could reduce the amount of surface water or saturation in the outer perimeter of the wetland. The wetland area directly affected from installation of the culvert would be in the rock-lined north bank of the channel and would not result in significant impacts to the wetland as no wetland vegetation would be removed. The culvert would be installed during the dry season to further reduce potential impacts to water quality. If surface water is present in the channel north of SW 23rd Street occurs during construction, a temporary barrier would be placed to prevent surface flow from the channel to the construction area. Surface flow could then be rerouted downstream of the project area using a bypass pump system. The system of sedimentation fences and strawbales discussed under element No. 1 would be in place to reduce sedimentation impacts to the water in the channel. Any wetland area temporarily disturbed from construction activities would be revegetated with shrubs common to the area. Placement of the new culvert would restore the drainage system north of the SW 23rd Street access road. Late spring surface water elevations in the channel within wetland W-7S could be reduced approximately 1.2 feet. (This is based on the difference of existing surface water 8 elevations in the channel portion of the wetland and water elevations associated with the proposed project in place.) Although the installation of the new culvert would reduce the frequency and depth of inundation during storm events along the channel, the scrub-shrub vegetation associated with this wetland is not expected to change. Species such as willow, reed canarygrass, and spirea growing in the wetland, and outside of the channel within the wetland, are tolerant of changes in water levels and are expected to adapt to the new hydrologic regime. High ground water within 12-18 inches of the surface of the wetland would continue to support the growth of scrub-shrub vegetation. Additional scrub-shrub vegetation may establish within the channel from the reduced water levels. (5) Remove sediment from the twin 9-foot by 14-foot culverts under Lind Avenue at SW 23rd Street and immediately upstream and downstream of the culvert openings. Sediment that supports approximately 970 square feet (0.02 acre) of emergent vegetation (American brooklime)would be removed from the pool downstream of the culvert openings. Wetland vegetation would not be affected in the area upstream of the culverts; sediment would be removed from an unvegetated area of approximately 590 square feet upstream of the culverts within the wetland. Wetland vegetation would not be affected in this small area where plants have not yet established. Protection of water quality downstream of the sediment removal area would be accomplished by working during low flows and bypassing the flows around the work area. Sediment samples will be taken before construction to evaluate sediment quality and disposal requirements. Straw bales placed in the channel would be in place to trap sediment and soil pollutants before reaching Springbrook Creek. 9.

Proposed Activity: The proposed activity consists of the 5 elements described below. The project would occur in existing channels along SW 23rd Street near Lind Avenue (see Figure 3). (1) Replace the existing 18 inch culverts under the Olympic Pipeline crossing of the SW 23rd Street channel with a new, large pre-cast concrete box culvert. The Olympic Pipeline Company petroleum product lines are located west of Lind Avenue. The pipelines are located in an upland berm separating the pool at the downstream outlet of the twin 9- by 14-foot culverts from the SW 23rd Street Channel. The existing 18 inch culverts connecting these two wetland areas are currently undersized and cause high upstream water surface elevations, contributing to the flooding problems along East Valley Road. The culverts are also subject to frequent plugging, allowing sedimentation and vegetation debris to fill in and choke the upstream channel. The inside dimensions of the new box culvert will be 10 feet wide, 4 feet high and 80 feet long. The new box culvert is designed for the pipelines to remain in their existing location (see Figures 4 and 5). Invert elevation of the box culvert inlet would be 6.6 feet (NAVD) to tie into the existing SW 23rd Street channel; invert elevation of the outlet would be 6.5 feet (NAVD). A channel approximately 10 feet long with 1.5:1 side slopes would be excavated in the upland area to connect the box culvert outlet with the existing SW 23rd Street channel. The inlet and outlet of the box culvert would be rock-lined to maintain the structural integrity of the culvert to channel connection. The remaining portions of the 1.5:1 side slopes of the channel would be revegetated with native low growing wetland shrubs. (2) Remove the abandoned beaver dam at the mouth of the SW 23rd Street channel as it enters Springbrook Creek west of Lind Avenue and south of the SW 23rd Street access road and selectively remove debris and vegetation between Springbrook Creek and Lind Avenue. 3 (4) Install a new 24-inch culvert parallel to and east of Lind Avenue to connect a small channel north of the SW 23rd Street access road to the SW 23rd Street channel, south of the access road to restore drainage system function. Because of the existing non-functioning 30-inch culvert that crosses Lind Avenue north of the SW 23rd Street channel, a new culvert would be installed to route flow from the small channel located north of SW 23rd Street and east of Lind Avenue to the SW 23rd Street channel. Development of the property north of the channel and west of Lind Avenue plugged the existing culvert approximately 10 years ago. Because this channel currently has no drainage outlet along Lind Avenue or SW 23rd Street, surface water no longer drains but collects in the channel and has created wetland conditions and flooding problems on the property north of SW 23rd Street and east of Lind Avenue. Installation of a new culvert would maintain the drainage system that was in place before the culvert was plugged. The new culvert would be a 24-inch diameter culvert with the inlet located just east of the existing 30-inch non-functioning culvert's inlet. The invert elevation of the north end of the new culvert, 12.0 feet (NAVD), is equal to the existing non-functioning culvert. The invert elevation of the south end of the new culvert would be 8.2 feet (NAVD), which is approximately 1.7 feet higher than the invert elevation of the existing 9-foot by 14-foot culverts under Lind Avenue south of SW 23rd Street. Riprap would be placed at the culvert's outlet to dissipate stormwater runoff entering into the SW 23rd Street channel. See Figures 6 and 7 for the plan and profile alignment design of the new culvert. (5) Remove sediment from the twin 9-foot by 14-foot culverts under Lind Avenue at SW 23rd Street and immediately upstream and downstream of the culvert openings. This activity is part of the periodic maintenance required to maintain the positive drainage along this portion of the SW 23rd Street channel. Approximately 2 to 3 feet of sediment has accumulated in the SW 23rd Street channel and at both openings of the twin culverts. A backhoe and/or vacuum truck positioned on the SW 23rd Street access road would remove this sediment to the invert elevation of the culverts. The sediment removal would occur within approximately 20 feet of the culvert opening on the east side of Lind Avenue, and within the pool area on the west side of Lind Avenue. Sediment would be disposed on an upland site. (Sediment within the culverts would be removed using a combination of human assisted shoveling and a vacuum device to bring the sediment to a truck/storage container on the access road.) Impacts on Project Elements 1-5: Cumulative impacts on wetlands from the proposed flood control maintenance activities are as follows: • permanent fill from placement of the new culverts or riprap at the outlets of the culverts would be approximately 300 square feet (the majority of the riprap fill would occur in areas where rock-lined channel banks or unvegetated channel bottoms exist); 5 Downstream water quality would be protected during construction by placement of sedimentation fences and rerouting surface flows back into the channel downstream of the construction area via a bypass pipe. A series of straw bales would be placed in the channel to contain sediment from the water in the bypass pipe. The bales would be removed after all construction is complete. Sediment would be removed if large enough quantities accumulated behind the bales. Temporary dewatering of the culvert construction area to allow for construction of the box culvert and other project elements could result in pumping of turbid water through the bypass system and into the SW 23rd Street channel. The straw bales in the channel would trap any sediment before reaching Springbrook Creek. Existing water elevations in Wetland W-8N during storm events are caused by the undersized culverts under the Olympic Pipeline crossing. Hydraulic modeling of surface water elevations within the SW 23rd Street channel indicate that the surface water elevations for a 2 year storm would be reduced by 2 feet by the culvert replacement. This is not expected to impact wetland acreage associated with wetland W-8N because (1) surface water connections between the channel and wetland W-8N would still occur and surface water would continue to inundate wetland W-8N, (2) base flow within the channel is not expected to change, and (3)two-year storm overflows into the wetland are relatively short in duration (less than one day) according to hydrologic/hydraulic simulation. The decrease in the maximum water levels during storm events is not expected to significantly change the wetland vegetation. Some herbaceous species may decrease (e.g., cattail and yellow flag)whereas other species may increase(e.g., sedges and rushes). Willow and spirea are species adapted to water level fluctuations and are expected to continue to dominate the wetland. (2) Remove the abandoned beaver dam at the mouth of the SW 23rd Street channel as it enters Springbrook Creek west of Lind Avenue and south of the SW 23rd Street access road and selectively remove debris and vegetation between Springbrook Creek and Lind Avenue. Removal of the small beaver dam which has deteriorated to a loose assemblage of sticks will not require any removal of wetland vegetation. No impacts on the channel or associated wetland are expected to occur. The beaver dam can be removed with hand held tools and equipment to avoid the disturbance of surrounding vegetation. Because the dam is loosely held together, base flow within the channel is not expected to change significantly to affect the surrounding wetland. High groundwater and surface flows associated with winter and spring storm events will continue to supply a source of water to support the scrub-shrub and forested wetland W-ION. Removal of debris and vegetation along the channel between Springbrook Creek and Lind Avenue would be done by selectively cutting lower growing vegetation hanging into the channel that obstructs flow. This activity would not directly impact the wetland or channel because only above ground material would be removed. The ground surface and soils would not be disturbed by the activity. Overhanging canopy from larger willows that does not obstruct channel flows would not be removed to maintain a shaded canopy over the channel. 7 elevations in the channel portion of the wetland and water elevations associated with the proposed project in place.) Although the installation of the new culvert would reduce the frequency and depth of inundation during storm events along the channel, the scrub-shrub vegetation associated with this wetland is not expected to change. Species such as willow, reed canarygrass, and spirea growing in the wetland, and outside of the channel within the wetland, are tolerant of changes in water levels and are expected to adapt to the new hydrologic regime. High ground water within 12-18 inches of the surface of the wetland would continue to support the growth of scrub-shrub vegetation. Additional scrub-shrub vegetation may establish within the channel from the reduced water levels. (5) Remove sediment from the twin 9-foot by 14-foot culverts under Lind Avenue at SW 23rd Street and immediately upstream and downstream of the culvert openings. Sediment that supports approximately 970 square feet (0.02 acre) of emergent vegetation (American brooklime)would be removed from the pool downstream of the culvert openings. Wetland vegetation would not be affected in the area upstream of the culverts; sediment would be removed from an unvegetated area of approximately 590 square feet upstream of the culverts within the wetland. Wetland vegetation would not be affected in this small area where plants have not yet established. Protection of water quality downstream of the sediment removal area would be accomplished by working during low flows and bypassing the flows around the work area. Sediment samples will be taken before construction to evaluate sediment quality and disposal requirements. Straw bales placed in the channel would be in place to trap sediment and soil pollutants before reaching Springbrook Creek. 9.

Describe current use of the property, including structures: The primary land use within the project site is urban. Parcels surrounding the project site where the work will occur are developed as busirte&;es or undeveloped pads. Wetland areas are present in many portions of the parcels that have not been filled (see Figure 2). Lind Avenue is a paved, public road. SW 23rd Street is a paved private access road (east of Lind Avenue) owned by Olympic Pipeline Company and a gated gravel acces road owned by the City of Seattle west of Lind Avenue. The SW 23rd Street channel is located south of SW 23rd Street and flows east to west. It crosses under Lind Avenue in twin 9- by 14-foot corrugated metal pipe culverts and discharges into Springbrook Creek approximately 950 feet west of Lind Avenue. Petroleum pipelines owned by Olympic Pipeline Company cross the SW 23rd Street channel west of Lind Avenue in a north to south direction and are enclosed in an earthen berm. Undersized 18-inch culverts currently connect the SW 23rd Street channel at this pipeline crossing and are subject to frequent plugging with debris and sediment.

Purpose: The objectives of the proposed project are to: DRAFF, July 11, 1997 PAGE 2 JUL-11-97 FRI 01 :49 PM FAX NO. P. 04 • restore drainage to the channel north of SW 23rd Street anii correct flooding of the property north of the SW 23rd Street access road and east of Lind Avenue; • improve surface water conveyance from the SW 23rd Street channel into Springbrook Creek; • reduce maintenance problems associated with the undersized culvert under the Olympic Pipeline Crossing and increasing the flood protection to Lind Avenue, East Valley Road, and other tributary areas; • improve the potential for fish passage from Springbrook Creek to the SW 23rd Street channel, add habitat for fish that is currently not accessible, and provide off-channel habitat during high Springbrook Creek flows.. Proposed Activity: The proposed activity consists of the 5 elements described below. The project would occur in existing channels along SW 23rd Street uc a A__- ._ (see Figure 3). (1) Replace the existing 18 inch culverts under the Olympic Pipeline crossing of the SW 23rd Street channel -olth a new, large pre-cast concrete box culvert. The Olympic Pipeline Company petroleum product lines are located west of Lind Avenue. The pipelines are Iocated in an upland berm separating the pool at the downstream outlet of the twin 9- by 14-foot culverts from the S\V 23rd Street Channel. The existing 18 inch culverts connecting these two wetland areas are currently undersized and cause high upstream water surface elevations, contributing to the flooding problems along East Valley Road. The culverts are: also subject to frequent plugging, allowing sedimentation and vegetation debris to fill in and choke the upstream channel. iv('`c_ The dimensions of the new box culvert will be 10 feet wide, 4 feet high and 75 feet long. The new box culvert is designed for the pipelines to remain in their existing location (see Figures 4 and 5). Invert elevation of the box culvert nutlet would be 6.6 feet (NAVD) to tie into the existing SW 23rd Street channel; invert elevation of the outlet would be 6.5 feet (NAVD), A channel approximately 10 feet long with 1.5:1 side slopes would be excavated in the upland area to connect the box culvert outlet with the existing SW 23rd Street channel. The inlet and outlet of the box culvert would be rock-lined to maintain the structural integrity of the culvert to channel connection. The remaining portions of the 1.5:1 side slopes of the channel would be revegetated with native low growing wetland shrubs. DRAFT, July 11, 1997 PAGE 3 JUL-11-97 FRI 01 :49 PM FAX NO. P. 05 (2) Remove the abandoned beaver dam at the mouth of the SW 23rd Street ' channel as it enters Springbrook Creek west of Lind Avenue and south of the SW 23rd Street access road. i s d r4"?,r r dcW►z Apo �e����' yet SI,,�,�b,.�k 4a�k a1 i4,d /av<. oThe abandoned beaver dam would be removed to reduce debris accumulation and v upstream sedimentation problems, reduce flood impacts, improve the potential o passage of fish from Springbrook Creek into the SW 23rd Street Channel, and ao o provide habitat during high Springbrook Creek flows. See Figure 3 for the location .° o of the abandoned beaver dam. The beaver dam is approximately 6 feet wide and 16" inches high within the ordinary high water mark of the channel and consists of small, U s, loose mix of willow twigs. (3) Remove accumulated herbaceous and shrub vegetation along 1,180 linear feet of the SW 23rd Street channel from East Valley Road to Lind Avenue. Removal of the vegetation is a periodic maintenance activity that would be done to ° restore a defined flow channel and help maintain positive drainage. Approximately 8,000 square feet of vegetation within the wetland (channel and the channel's north 3 ° bank) would be removed. Young shrub vegetation would be removed in the upland bi) area and a narrow strip of wetland along the channel's north bank; emergent s vegetation would be removed within the wetland in the channel. CZ � - The existing SW 23rd Street channel along this reach is a V-shaped channel and o ° varies in width froin 10 to 25 feet at the elevation of the adjacent wetland area. Its depth below the ground surface of the wetland to the south, varies from o approximately 2 to 5 feet. The surface of the adjacent private road is approximately 7 to 12 feet higher in elevation than the bottom of the channel. � 3 Vegetation removal along the south bank would be cut just above the ground surface, o E. Reed canarygrass (Phalaris arundinacea), black cottonwood (PolMus trichocaipa) a saplings, and Himalayan blackberry (Rubus discolor) would be the dominant .o vegetation to be removed. Other wetland shrubs such as Douglas' spirea (Spiraea douglasii), red-osier dogwood (Corpus stolonifera), and willow (Salir sp.) would also ° be cut. Vegetation would be cut from the edge of the SW 23rd Street road surface, the upland portion of the banks, to the water surface. Because of the steep north channel bank (2:1), a narrow strip of shrub vegetation within the wetland area on the north channel bank would be cut (approximately 2 feet wide). In addition, in those 3 areas where emergent vegetation is growing in the channel, the above ground portion o 2 of the vegetation would be removed by scraping the vegetation at the ground surface Y > from the channel with a backhoe. No widening or deepening of the channel or soil 'U .N disturbance is intended from this maintenance activity. The backhoe would operate from the SW 23rd Street access road. L N 'E N DRAF=;t', July 11, 1997 PAGE 4 Q ¢ ,E JUL-11-97 FRI 01 :50 PM FAX N0, P. 06 (4) Install a new 30-inch culvert parallel to and east of Lind Avenue to connect a small channel north of the SW 23rd Street access road to the SW 23rd Street channel, south of the access road to restore drainage system function. Because of the existing non-functioning 30-inch culvert that crosses Lind Avenue north of the SW 23rd Street channel, a new culvert would be installed to route flow from the small channel Iocated north of SW 23rd Street and cast of Lind Avenue to the SW 23rd Street channel. Development of the property north of the channel and west of Lind Avenue plugged the existing culvert approximately 10 years ago. Because this channel currently has no drainage outlet along Lind Avenue or SW 23rd Street, surface water no longer drains but collects in the channel and has created wetland conditions and flooding problems on the property north of SW 23rd Street and east of Lind Avenue. Installation of a new culvert would maintain ilie drainage system that was in place before the culvert was plugged. le"A 'I'he new culvert would be a 30-inch diameter culvert with the inlet cc�g the existing 30-inch non-functioning culvert's inlet. The invert elevation of the north end of the new culverV,)11.47 feet (NAVE)), is equal to the existing non-functioning culvert. The invert elevation of the south end of the new culvert would be 7.7 feet (NAVD), which is approximately 1.2 feet higher than the invert elevation of the existing 9-foot by 14-foot culverts under Und Avenue south of SW 23rd Street. Riprap would be placed at the culvert'.-; outlet to dissipate stormwater runoff entering into the SW 23rd Street channel. See figures 6 and 7 for the plan and profile alignment design of the new culvert. (5) Remove sediment from the twin 9-foot by 14-foot culverts under Lind Avenue at SW 23rd Street and immediately upstream and downstream of the culvert openings. This activity is part of the periodic maintenance required to maintain the positive drainage along this portion of the SW 23rd Street channel. Approxiirtately 2 to 3 feet of sediment has accumulated in the SW 23rd Street channel and at both openings of the twin culverts. A backhoe and/or vacuum truck positioned on the SW 23rd Street access road would remove this sediment to the invert elevation of the culverts, The sediment removal would occur within approximately 20 feet of the culvert opening on the east side of Lind Avenue, and within the pool area on the west side of Lind Avenue, Sediment would be disposed on an upland site. (Sedinent within the culverts would be removed using a combination of human assisted shoveling and a vacuum device to bring the sediment to a truck/storage container on the access road_) Impacts on Project Elements 1-5: Cumulative impacts on wetlands from the proposed a activities are as follows: DRAB-, July 11, 1997 PAGE 5 JUL-11-97 FR I 01 :51 Pit FAX N0, P. 07 • permanent fill from placement of the new culverts or riprup at the outlets of the culverts would be 283 square feet (the majority of the riprap fill would occur in areas where rock-lined channel banks or unve-etated channel bottoms exist); • temporary disturbance from the construction related activi1.ies to place the new culverts would be 215 square feet (temporary disturbance occurs primarily on rock-lined banks and unvegetated channel bottoms); and • temporary disturbance from the removal of accumulated sediment at the inlet and outlet of the twin culverts would be 1,387 square feet (to a depth of approximately 2,5 feet would equal 128 cubic yards). The total impacts on wetlands from improvements to the culvert drainage system would be 1,885 square feet (0.04 acre). In addition, vegetation maintenance along the SW 23rd Street channel would temporarily remove approximately 8,000 square feet of young shrub and herbaceous plants from the channel brinks and bottom. Specific impacts from each of the five project elements are discussed below. (1) Replace the existing 18 inch culverts under the Olympic Pipeline crossing of the SW 23rd Street channel with a new pre-cast concrete box culvert . Impacts from the nvw=4mK culvert, will occur from the con�y ,ction of the box culvert's inlet structure within a small portion of the wetlan4 Construction of the channel connecting the new box culvert to the existing SW 23rd Street channel (see Figure 4). Temporary construction impacts and the installation of the new box culvert are expected to be hinited to an area of 341 square feet of wetland. Downstream sedimentation issues will be minimized by routing any channel flow that may occur during construction in a bypass pipe. The area where work will occur will be be protected from the rest of the channel by sedimentation fences. Work would be scheduled to occur outside of the wet season during low flows. Wetland area that will be impacted is primarily rock lined slopes where the new box culvert's inlet and outlet occur, At the outlet, scrub-shrub vegetation (willow and red-osier dogwood) is growing at and above the wetland boundary (approximately the ordinary high water line). Several willow and/or red-osier dogwood plants would Iikely be removed for placement of the new box culvert. The new channel slopes that are to he constructed connecting the box culvert to the existing SW 23rd street channel would be revegctated with native low growing shrubs to compensate for the DRAF1', July 11, 1997 PAGE 6 JUL711-97 FRI 01 :51 PM FAX N0, P. 08 vegetation removed to construct the channel. Approximately 185 square feet of wetland and channel bottom would be created from construction of the new channel. No impacts to fish are expected to occur. Fish have not been observed in the channel and current use would he limited by the downstream beaver dam. The proposed project replaces culverts that are a barrier to fish with a fish passable culvert. Downstream. water quality would be protected during constriction by placement of sedimentation fences and rerouting surface flows back into the channel downstream of the construction area via a bypass pipe. A series of straw bales would be placed in the channel to contain sediment from the water in in the bypass pipe. The bales would be removed after all construction is complete. Sediment would be removed if large enough quantities accumulated behind the bales. Temporary dewatering of the area to allow for construction of the box culvert and other project elements could /Ifesult in pumping of turbid water through the bypass system and into the SW 23rd Street channel. 'i'lie straw bales in the channel would trap any sediment before reaching Springbrook Creek. t� ,�• Existing water elevations in Wetland W-8N during storm events are cuased by the U� undersized culverts under the Olympic Pipeline crossing. Hydraulic modeling of surface water elevations within the SW 23rd Street channel indicate that the surface water elevations for a 2 year storm would be reduced by 2 feet by the culvert replacement. This is not expected to impact wetland acreage associated with wetland W-8N because (1) surface water connections between the channel and wetland W-8N would still occur and surface water would continue to inundate wetland WBN, (2) base flow within the channel is not expected to change, and (3) two-year storm overflows into the wetland are relatively short in duration (less than one day) according to hydrologic/hydraulic simulation. The decrease in the maximum water levels during storm events is not expected to significantly change the wetland vegetation. Some herbaceous species may decrease (e.g., cattail and yellow flag) whereas other species may increase (e.g., sedges and rushes). Willow and spirea are species adapted to water Ievel fluctuations and are expected to continue to dominate the wetland. (2) Remove the abandoned beaver dam at the mouth of the SW 23rd Street channel as it enters Springbrook Creek west of Lind Avenue anti south of the SW 23rd Street access road,a.d seaP-�,,-,-'7 te.,vt d4ri'r f,,) r4!1 o",' 6e¢w-et-r� SP ,) b-e k 4 c,sl Z,..,1 A..-4rA'-p- - Removal of the smalebeaver dam which has deteriorated to a loose. assemblage of sticks will not require any removal of wetland vegetation. No impacts on the channel or associated wetland are expected to occur. The beaver dam can be removed with DRAFT, July 11, 1997 PAGE 7 JUL711-97 FRI 01 :52 PM FAX N0, P. 09 hand held tools and equipment to avoid the disturbance of surrounding vegetation. Because the dam is loosely held together, base flow within the channel is not expected to change significantly to affect the surrounding wetland. Digh groundwater and surface flows associated with winter and spring storm events will contine to supply a source of water to support the scrub-shrub and forested wetland W-10N. (3) Remove accumulated herbaceous and shrub vegetation along 1,180 linear feet of the SW 23rd Street channel from East Valley Road to Lind Avenue. Vegetation will be cleared along the south bank of the chan.ael and within the channel. Vegetation will be cleared by mowing and scraping and would not affect the topography of the wetland. Although the removal of vegetation would result in the loss of some wildlife habitat, the amount lost is incremental relative to the amount of surrounding scrub-shrub habitat in wetlands W-8N, W-7S, and W-10N. Fish passage in the channel will be improved and this reach will be restored as off- channel habitat for Springbrook Creek after the Olympic Pipeline culvert is replaced (see Element 1). Emergent vegetation to be removed from the cha.rinel include common cattail (Typha latifolia), American brooklime (Veronica americana), reed eanarygrass, and yellow flag (Iris pseudacoru_s), (4) Install a new 30-inch culvert parallel to and east of Lind Avenue to connect a small channel north of the SW 23rd Street access road to the SW 23rd Street channel, south of the access road to restore drainage system function. Impacts associated with installation of the new culvert would occur from placement of the culvert's outlet into the SW 23rd Street channel. Approximately 83 square feet of wetland W-8N would be disturbed where the culvert daylights into the wetland's channel bank; approximately 75 square feet of wetland W-7S would be temprarily disturbed by construction activities to install the culvert at the inlet. Restoring the drainage system function would return the hydrology in the channel On the north side of the the private access road and wetland W-7S to conditions that existed before the existing culvert was plugged. Re-establishing the drainage front wetland W-7S to wetland W-8N could result in the potential loss of approximately 0.8 acre of the 1.75 acre wetland W-7S from lowering of surface water elevations. The wetland area directly affected from installation of the culvert would be in the rock-lined north bank of the channel and would not result in significant impacts to the wetland as no wetland vegetation would be removed. The Culvert would be installed during the dry season to further reduce potential impacts to water quality. If Surface water is present in the channel north of SW 23rd Street occurs during construction, a temporary barrier would be placed to prevent surface flow from the channel to the construction area, Surface flow could then be rerouted downstream of the project area using a bypass pump system. The system of sedimentation fences DRAI'`I', July 11, 1997 PAGE 8 JUL711-97 FRI 01 :52 PM FAX NO, P. 10 and strawbales discussed under element No. 1 would be in place to reduce sedimentation impacts to the water in the channel. Any wetland area temporarily disturbed from construction activities would be revegetated with shrubs common to the area, Placement of the new culvert would restore the drainage system north of the SW 23rd Street access road. Late spring surface water elevations in the channel within wetland W-7S could be reduced approximately 1.8 feet, (This is based on the difference of existing water elevations in the wetland and water elevations associated with the proposed project in place.) Although the installation of the new culvert would reduce the frequency and depth of inundation during storm events along the channel, the scrub-shrub vegetation associated with this wetland is not expected to change, Species such as willow, reed canarygrass, and spirea growing in the wetland, and outside of the channel within the wetland, are tolerant of changes in water levels and are expected to adapt to the new hydrologic regime. High ground water within 18-24 inches of the surface of the wetland would continue to support the growth of scrub-shrub vegetation. Additional scrub-shrub vegetation may establish within the channel from the reduced water levels. (5) Remove sediment from the twin 9-foot by 14•foot culverts tinder Lind Avenue at SW 23rd Street and immediately upstream and downstream of the culvert openings. Sediment that supports approximately 970 square feet (0.02 ,acre) of emergent vegetation (American brooklime) would be removed from the pool downstream of the culvert openings. Wetland vegetation would not be affected in the area upstream of the culverts; sediment would 'be removed from an unvegetated area of approximately 590 square feet upstream of the culverts within the wetland. Wetland vegetation would not be affected in this small area where plants have not yet established. Protection of water quality downstream of the scdirnerit removal area would be accomplished by working during low flows and bypassing; the flows around the work area. Sediment samples will be taken before construction to evaluate sediment quality and disposal requirements, Straw bales placed in the channel would be in place to trap sediment and soil pollutants before reaching Spr.ingbrook Creek. 9.

P. 16 Wetland Delineation Report City of Renton SW 23rd Street Flood and Drainage Improvements Introduction This report presents the results of a wetland delineation conducted May 23, 1997 for the City of Renton's SW 23rd Street flood and drainage improvement project. Wetland delineations were conducted within the areas where construction will occur and where structures will be placed for drainage improvements. The wetland delineation was conducted using the U.S, Army Corps of Engineers Wetland Delineation Manual (Environmental Laboratory 1987). This method is summarized in Appendix A. This report has been prepared for the City of Renton Public Works Department and is ,intended to be used for the following purposes: • U.S. Army Corps of Engineers review of the project. The Corps is the federal agency that regulates the discharge of dredge and fill material into wetlands and Waters of the United States. This report will be submitted to the Corps for verification of the delineation and as part of the Joint Aquatic Resource Permit Application. • City of Renton Planning Department review of the project as part of the SEPA process and for compliance with the City of Renton's wetland regulations as stated in the City's sensitive areas ordinance. This report is a stand alone document and presents project description, results of the delineation, functions and values of the portion of wetlands within the project area, project impacts, and methods used for the delineation. The wetland delineation was based on best professional stand<irds using accepted field methods. Final verification of jurisdictional wetland boundaries, however, is the responsibility of the Corps. Project Location The project site is located at the intersection of SW 23rd Street and Lind Avenue in Renton, Washington (Figures 1 and 2), Proposed activities would occur along the channel tsCMUND AybStIr•.WMAND DRAFT-yoR INTERNAL RCYIt;W ONLY 07/11197u JUL-11-97 FRI 01 :56 PM FAX N0, P. 17 4�J south of SW 23rd Street itnme_ , as d in a ditch north of SW 23rd Street channel andneast of Lind Avenue. ►T r Project Description The general purpose of the proposed project is to maintain and improve the existing flood control and drainage systems along SW 23rd Street at Lind Avenue in Renton, Washington. The existing system is not functioning to provide adequate flood control as existing culverts are undersized or plugged, and existing channels have become reduced in capacity and flow capability with sediment or vegetation. The objectives of the proposed project are to: • restore drainage to the channel north of SW 23rd Street and correct flooding of the property north of the SW 23rd Street access road and east of Lind Avenue; • improve surface water conveyance from the SW 23rd Street channel into Springbrook Creek; • reduce maintenance problems associated with the undersized culvert under the Olympic Pipeline Crossing and increasing the flood protection to Lind Avenue, East Valley Road, and other tributary areas; • improve the potential for fish passage from Springbrook Creek to the SW 23rd Street channel, add habitat for fish that is currently not accessible, and provide off-channel habitat during high Springbrook Creek flows. The proposed activity consists of the 5 elements described below. The project would occur in existing channels along SW 23rd Street near Lind Avenue (see Figure 3). (1) Replace the existing 18 inch culverts under the Olympic Pipeline crossing of the SW 23rd Street channel with a new, large pre-cast concrete box culvert. The Olympic Pipeline Company petroleum product lines are located west of Lind Avenue. The pipelines are located in an upland berm separating the pool at the downstream outlet of the twin 9- by 14-foot culverts from the SW 23rd Street Channel. The existing 18 inch culverts connecting these two wetland areas are currently undersized and cause high upstream water surface elevations, contributing to the flooding problems along East Valley Road. The culverts are also subject to frequent plugging, allowing sedimentation and vegetation debris to fill in and choke the upstream channel. The dimensions of the new box culvert will be 10 feet wide, 4 feet high and(`7S eet long. The new box culvert is designed for the pipelines to remain in their existing location (see Figures 4 and 5). Invert elevation of the box culvert outlet would be 6.6)feet (NAVD) to tie into the existing SW 23rd Street channel; invert elevation of the outlet would be BECK/UND AVFNUE WETLAND DRAFT-yo R INTERNAL REVIEW ONLY 07/11/47u y h JUL711-97 FRI 01 :56 PM FAX NO. P. 18 b � -d 6.5 feet (NAND). A channel approximately L et long with P:1 side slopes would be y excavated in the upland area to connect the box culvert outlet with the existing SW 23rd Street channel, The inlet and outlet of the box culvert would be rock-line to v ° maintain the structural integrity of the culvert to channel connection. The remaining o ° portions of the 1.5:1 side slopes of the channel would be revegetated with native low o growing wetland shnibs. (2) Remove the abandoned beaver dam at the mouth of the SW 23rd Street channel as it enters Springbrook Creek west of Lind Avenue and south of the SW 23rd Street access road. 6A4 Se/ems+"e /7 ,c,�„rc d��u <,�� �/c�e#k*Joh The abandoned beaver dam would be removed to reduce debris accumulation and o upstream sedimentation problems, reduce flood impacts, improve the potential passage of fish from Springbrook Cheek into the SW 23rd Street Channel, and provide habitat during high Springbrook Creek flows. See Figure 3 for the location of the abandoned beaver dam. The beaver dam is approximately 6 feet wide and 16" inches high within the ordinary high 3 ° water mark of the channel and consists of small, loose mix of willow twigs. �C? v�al9/• �ni ��5�/f. q (3) Remove accumulated herbaceous and shrub vegetation along 1,180 linear feet .E of the SW 23rd Street channel from East Valley Road to Lind Avenue. c � y Removal of the vegetation is a periodic maintenance activity that would be done to restore a defined flow channel and help maintain positive drainage. Approximately o 8,000 square feet of vegetation within the wetland (channel and the ch,, el s north bank) �_ would be removed. Young shrub vegetation would be removed in the upland area and a '3 narrow strip of wetland along the channel's north bank; emergent vegetation would be y removed within the wetland in the channel. E The existing SW 23rd Street channel along this reach is a V-shaped channel and varies in width from 10 to 25 feet at the elevation of the adjacent wetland area. Its depth below the ground surface of the wetland to the south, varies from approximately 2 to 5 feet. The surface of the adjacent private road is approximately 7 to 12 feet higher in elevation c than the bottom of the channel. Vegetation removal along the south bank would be cut just above th e ground surface. 3 E Reed canarygrass (Phalaris arundinacea), black cottonwood (Populus trr.chocarpa) saplings, o and Himalayan blackberry (Rubus discolor) would be the dominant vegetation to be y removed. Other wetland shrubs such as Douglas' spirea (Spiraea dvuglusii), red-osier � ,'z N dogwood (Corpus stolonzfera), and willow (Salix sp.) would also be cut.

The backhoe would operate from the SW 23rd Street access road. (4) Install a new 30-inch culvert parallel to and east of Lind Avenue to connect a small channel north of the SW 23rd Street access road to the SW 23rd Street channel, south of the access road to restore drainage system function. Because of the existing non-functioning 30-inch culvert that crosses Lind Avenue north of the SW 23rd Street channel, a new culvert would be installed to route flow from the small channel located north of SW 23rd Street and east of Lind Avenue to the SW 23rd Street channel. Development of the property north of the channel and west of Lind Avenue plugged the existing culvert approximately 10 years ago. Because this channel currently has no drainage outlet along Lind Avenue or SW 23rd Street, surface water no longer drains but collects in the channel and has created wetland conditions and flooding problems on the property north of SW 23rd Street and east of Lind Avenue. Installation of a new culvert would maintain the drainage system that was in place htfore the culvert was plugged, The new culvert would be a 30-inch diameter culvert with the inlet cennee6ng the existing 30-inch non-functioning cu culvert's inlet, Tht, invert elevation of the north end of the new culver/t-.�11.47 feet (NAVD), is equal to the existing non- functioning culvert.

Riprap would be placed at the culvert's outlet to dissipate stormwater runoff cantering into the SW 23rd Street channel. See Figures 6 and 7 for the plan and profile alignment design of the new culvert. (S) Remove sediment from the twin 9-foot by 14-foot culverts under Lind Avenue at SW 23rd Street and immediately upstream and downstream of the culvert openings. This activity is part of the periodic maintenance required to maintain the positive drainage along this portion of. the SW 23rd Street channel. Approximately 2 to 3 feet of sediment has accumulated in the SW 23rd Street channel and at both openings of the twin culverts, A backhoe and/or vacuum truck positioned on the SW 23rd Street access road would remove this sediment to the invert elevation of the culverts. The sediment removal would occur within approximately 20 feet of the culvert opening on the east side of Lind Avenue, and within the pool area on the west side of Lind Avenue. Sediment would be disposed on an upland site. (Sediment within the culverts would bc: removed using a combination of human assisted shoveling and a vacuum device to bring the sediment to a truck/storage container on the access road.)

Parcels surrounding the project site where the work will occur are developed as businesses or undeveloped pads. Wetland areas are present in many portions of the parcels that have not been filled (see Figure 2). Lind Avenue is a paved, public road. SW 23rd Street is a paved private access road (east of Lind Avenue) owned by Olympic Pipeline Company and a gated gravel access road owned by the City of Seattle west of Lind Avenue, The SW 23rd Street channel is located south of SW 23rd Street and flows east to west. It crosses under Lind Avenue in twin 9- by 14-foot corrugated metal pipe culverts and discharges into Springbrook Creek approximately 950 feet west of Lind Avenue. Petroleum pipelines owned by Olympic Pipeline Company cross the SW 23rd Street channel west of Lind Avenue in a north to south direction and are enclosed in an earthen berm. Undersized 18-inch culverts currently connect the SW 23rd Street channel at this pipeline crossing and are subject to frequent plugging with debris and sediment. A separate, smaller channel is located north of SW 23rd Street with an east to west �r direction. A 30-inch culvert crossing under Lind Avenue connects the smaller channel to Aye ["no the SW 23rd Street Channel; however, the culvert was inadvertently plugged in the mid 1980s from the development of. the parcel west of Lind Avenue; and north of ✓���� SW 23rd Street. Water in the channel north of SW 23rd Street and east of Lind Avenue longer has an outlet because of the plugged condition of the culvert under Lind Avenue. The SW 23rd Street channel lies within two larger wetland areas previously identified in the City of Renton's wetland inventory database, Wetland W-8N occurs east of Lind Avenue and Wetland W-10N is west of Lind Avenue. The ditch north of SW 23rd Street lies within Wetland W-7S. The channels where the proposed activity would occur are considered part of the larger wetlands because (1) the SW 23rd Street channel is contiguous with wetland W-8N and on the east and west side of Lind Ave3lue, (2) the channel north of SW 23rd Street i contiguous with wetland W-7S, and (3) portions of the channel (bank and bottom) are v getated (although portions of the proposed activities occur where the channels are unve J tated).

P. 22 wetlands where project activity would occur. Figures 4 and 6 show the wetland boundary in the project area. See Appendix B for wetland data sheets. Wetland W-7S Wetland W-7S is a long linear ditch with a narrow portion of the ditch (5 to 10 feet wide) containing open water during the time of the delineation. The ditch banks are vegetated with scrub-shrub and herbaceous vegetation as discussed below. The west end of Wetland W-7S was delineated for this project where the non-functioning culvert is located. This portion of the wetland that would be directly affected by installation of the culvert under SW 23rd Street is a palustrine scrub-shrub wetland. The features of this portion of the wetland are described below. Vegetation. Vegetation is dominated by Sitka willow (Salix sitchenszr), red-osier dogwood, and reed canarygrass. The vegetation is growing on the banks of the ditch around the standing water in the ditch at the opening of the non-functioning culvert. Vegetation in the upland surrounding the wetland area is dominated by Himalayan blackberry, reed canarygrass, and red alder (Alnus rubra). Hydrology. Wetland hydrology is supported by surface water runoff from surrounding upland areas that collects in the ditch. Water depths in the ditch ranged from 12 to 22 inches during the time of the delineation. Inundation within the ditch varies from seasonal to perennial depending upon the amount of yearly precipitation. During the time of the delineation, saturated soils along the banks and low terraces adjacent t,;) the ditch were associated with the groundwater in the general area. Surface water does not drain into other wetlands or channels because of the plugged condition of the existing culvert. Soils. Soils in this portion of the wetland were mapped as urban by the Soil Conservation Service (SCS 1973). Soil characteristics in the upper 10 inches of the vegetated portion of the wetland were silt loam texture, matrix colors of 10YR 3/2 with 10YR 4/1 and 10YR 3/6 mottles, and sulfidic smells. Upland soil characteristics were sandy loam texture with a matrix color of 10YR 3/3 with very few 10YR 3/6 mottles. Soils were "dry" as determined by the; dListy nature of the soil as it was removed from the soil pit. Wetland W-SN Wetland W-8N is scnib-shrub wetland with the SW 23rd Street channel forming the northern border of the wetland. The west end of the channel was delineated for this project where the south end of the new culvert will be placed under SW 23rd ,street and where sediment will be removed upstream from the existing 9-foot by 14-foot culverts running under Lind Avenue. This portion of the wetland that would be directly affected by project activities is open water with scattered vegetation along the rock-lined banks.

The total impacts on wetlands from improvements to the culvert drainage system would be 1,885 square feet (0,04 acre). In addition, vegetation maintenance along the SW 23rd Street channel would temporarily remove approximately 8,000 square feet of young shrub and herbaceous plants from the channel banks and bottom.

Specific impacts from each of the five project elements are discussed below, (1) Replace the existing 18 inch culverts under the Olympic Pipeline crossing of the SW 23rd Street channel with a new pre-cast concrete box culvert.

Temporary construction impacts, and the installation of the new box culvert are expected to be limited to an area of,341square feet of wetland. Downstream sedimentation issues will be minimized by routing any channel flow that may occur during construction in a bypass pipe- The area where work will occur will be protected from the rest of the channel by sedimentation fences. Work would be scheduled to occur outside of the wet season during low flows. Wetland area that will be impacted is primarily rock lined slopes where the new box culvert's inlet and outlet occur. At the outlet, scrub-shrub vegetation (willow and red-osier dogwood) is growing at and above the wetland boundary (approximately the ordinary high water line). Several willow and/or red-osier dogwood plants would likely be removed for placement of the new box culvert. The new channel slopes that are to be constructed connecting the box culvert to the existing SW 23rd street channel would be revegetated with native low growing shrubs to compensate for the vegetation removed to construct the channel. Approximately 185 square feet of wetland and channel bottoin would be created from construction of the new channel. v DUCK/11NDAVF.NUCu'LTLAND // DRArT-FOR INTERNAL REVIEW ONLY 07/11/97u ) 0 JUL-11-97 FRI 02:01 Phi FAX N0, P. 27 No impacts to fish are expected to occur. Fish have not been observed in the channel and current use would be limited by the downstream beaver dam. The proposed project replaces culverts that are a barrier to fish with a fish passable ccllvert. Downstream water quality would be protected during construction by placement of sedimentation fences and rerouting surface flows back into the channel downstream of the construction area via a bypass pipe. A series of straw bales would be placed in the channel to contain sediment from the water in the bypass pipe. The bales would be removed after all construction is complete. Sediment would be removed if large enough quantities accumulated behind the hales. Temporary dewatering of the area to allow for construction of the box culvert and other project elements could result in pumping of turbid water through the bypass system and into the SW 23rd Street channel. The straw bales in the channel would trap any sediment before reaching Springbrook Creek. Existing water elevations in Wetland W-8N during storm events are caused by the undersized culverts under the Olympic Pipeline crossing. Hydraulic m0delirlg of surface water elevations within the SW 23rd Street channel indicate that the surface water elevations for a 2-year storm would be reduced by 2 feet by the culvert replacement, This is not expected to impact wetland acreage associated with wetland W-8N because (1) surface water connections between the channel and wetland W-8N would still occur and surface water would continue to inundate wetland W-8N, (2) base flow within the channel is not expected to change, and (3) 2-year storm overflows into the wetland are relatively short in duration (less than one day) according to hydrologic/hydraulic simulation. The decrease in the maximum water levels during storm events is not expected to significantly change the wetland vegetation. Some herbaceous species may decrease (e.g., cattail and yellow flag) whereas other species may increase(e.g., sedges and rushes). Willow and spirea are species adapted to water level fluctuations and are expected to continue to dominate the wetland.

The beaver dam can be removed with hand held tools and equipment to avoid the disturbance of surrounding vegetation. Because the dam is loosely held together, base flow within the channel is not expected to change significantly to affect the surrounding wetland.

Vegetation will be cleared along the south bank of the channel and within the channel. Vegetation will be cleared by mowing and scraping and would not affect the topography of the wetland. Although the removal of vegetation would result in the loss of some wildlife habitat, the amount lost is incremental relative to the amount of surrounding scrub-shrub habitat in wetlands W-8N, W-7S, and W-10N, Fish passage in the channel will be improved and this reach will be restored as off-channel habitat for Sp:ringbrook Creek after the Olympic Pipeline culvert is replaced (see Element 1). Emergent vegetation to be removed from the channel include common cattail (Typha latifolia), American brooklime (Veronica umericana), reed canarygrass, and yellow flag (Iris pseudacoms). (4) Install a new 30-inch culvert parallel to and east of Lind Avenue to connect a small channel north of the SW 23rd Street access road to the SW 23rd Street channel, south of the access road to restore drainage system function. Impacts associated with installation of the new culvert would occur from placement of the culvert's outlet into the SW 23rd Street channel. Approximately 83 square feet of wetland W-8N would be disturbed where the culvert daylights into the wetland's channel bank; approximately 75 square feet of wetland W-7S would be temporarily disturbed by construction activities to install the culvert at the inlet, Restoring the drainage system function would return the hydrology in the channel on the north side of the private access road and wetland W-7S to conditions that existed before the existing culvert was plugged. Re-establishing the drainage from wetland W-7S to wetland W-8N could result in the potential loss of approximately 0.8 acre of the 1.75 acre wetland W-75 from lowering of surface water elevations. The wetland area directly affected from installation of the culvert. would be in the rock-lined north bank of the channel and would not result in significant impacts to the wetland as no wetland vegetation would be removed. The culvert would be- installed during the dry season to further reduce potential impacts to water quality. if surface water is present in the channel north of SW 23rd Street occurs during constnuction, a temporary barrier would be placed to prevent surface flow from the channel to the construction area. Surface flow could then be rerouted downstream of the project area ils-ing a bypass pump system. The system of sedimentation fences and strawbales discussed under element No. 1 would be in place to reduce sedimentation impacts to the water in the channel. Any wetland area temporarily disturbed from construction activities would be revegetated with shrubs common to the area, Placement of the new culvert would restore the drainage system north of the SW 23rd Street access road. Late spring surface water elevations in the channel within wetland W-7S could be reduced approximately 1.8 feet. (This is based on the difference of existing water elevations in the wetland and water elevations associated with the proposed project in place.)

Species such as willow, reed canarygrass, and spirea growing in the wetland, and outside of the channel within the wetland, are tolerant of changes in water levels and are expected to adapt to the new hydrologic regime. High ground water within 18 to 24 inches of the surface of the wetland would continue to support the growth of scrub-shrub vegetation. Additional scrub-shrub vegetation may establish within the channel from the reduced water levels. (5) Remove sediment from the twin 9-foot by 14-foot culverts under Lind Avenue at SW 23rd Street and immediately upstream and downstream of the culvert openings. Sediment that supports approximately 970 square feet (0.02 acre) of emergent vegetation (American brooklime) would be removed from the pool downstream of the culvert openings. Wetland vegetation would not be affected in the area upstream of the culverts; sediment would be removed from an unvegetated area of approximately 590 square feet upstream of the culverts within the wetland, Wetland vegetation would not be affected in this small area where plants have not yet established. Protection of water quality downstream of the sediment removal area would be accomplished by working during low flows and bypassing the flows around the work area. Sediment samples will be taken before construction to evaluate sediment quality and disposal requirements. Straw bales placed in the channel would be in place to trap sediment and soil pollutants before reaching Springbrook Creek. Citations Environmental Laboratory. 1973.

P. 32 Nationwide Permits / Corps Seattle District / 22 February 1997 (ii) Constructed by the Corps and transferred to a local sponsor for operation and maintenance. The maintenance is limited to that approved in a maintenance baseline determination made by the District Engineer. The prospective permittee will provide the District Engineer with sufficient evidence for the District Engineer to determine the approved and constructed baseline. Subsequent to the determination of the maintenance baseline and prior to any maintenance work, the permittee must notify the District Engineer in accordance with the Notification general condition. All dredged material must be placed in an upland site or a currently authorized disposal site in waters of the United States, and proper siltation controls must be used. This NWP does not authorize the removal of sediment and associated vegetation from natural water courses. (Activities that involve only the cutting and removing of vegetation above the ground, e.g., mowing, rotary cutting, and chainsaving, where the activity neither substantially disturbs the root system nor involves mechanized pushing, dragging, or other similar activities that redeposit excavated soil material, does not require a Section 404 permit in accordance with 33 CFR 323.2(d)(2)(ii)). Only constructed channels within stretches of natural rivers that have been previously authorized as part of a flood control facility could be authorized for maintenance under this NWP. Maintenance Baseline. Upon receipt of sufficient evidence, the District Engineer will determine the maintenance baseline. The maintenance baseline is the existing flood control project that the District Engineer has determined can be maintained under this NWP, subject to any case-specific conditions required by the District Engineer. In determining the maintenance baseline, the District Engineer will consider the following factors: the approved facility, the actual constructed facility, the Corps constructed project that was transferred, the maintenance history, if the facility has been functioning at a reduced capacity and for how long, present vs. original flood control needs, and if sensitive/unique functions and values may be adversely affected. Revocation or modification of the final determination of the maintenance baseline can only be done in accordance with 33 CFR Part 330.5. This NWP cannot be used until the District Engineer determines the maintenance baseline and the need for mitigation and any regional or activity-specific conditions. The maintenance baseline gill only be determined once and will remain valid for any subsequent reissuance of this NWP. However, if the project is effectively abandoned or reduced due to lack of proper maintenance, a new determination of a maintenance baseline would be required before this NWP could be used for subsequent maintenance. Mitigation. In determining the need for mitigation, the District Engineer will consider the following factors: any original mitigation required, the current environmental setting, and any adverse effects of the maintenance project that were not mitigated in the original construction. The District Engineer will not delay needed maintenance for completion of any required mitigation, provided that the District Engineer and the 57 JUL-11-97 FRI 02:05 PM FAX N0, P. 33 Nationwide Permits / Corps Seattle District / 22 February 1997 applicant establish a schedule for the identification, approval, development, construction and completion of such required mitigation.

Proposed Activity: The proposed activity consists of the 5 elements described below. The project would occur in existing channels along SW 23rd Street ue L� (see Figure 3). cleeh ��V."V (1) Replace the existing 18 inch culverts under the Olympic Pipeline crossing of the SW 23rd Street channel with a new, large pre-cast concrete box culvert. The Olympic Pipeline Company petroleum product lines are located west of Lind Avenue, The pipelines are Iocated in an upland berm separating the pool at the downstream outlet of the twin 9- by 14-foot culverts from the SW 23rd Street Channel. The existing 18 inch culverts connecting these two wetland areas are currently undersized and cause high upstream water surface elevations, contributing to the flooding problems along East Valley Road. The culverts are also subject to frequent plugging, allowing sedimentation and vegetation debris to fill in and choke the upstream channel. 'k The^dimensions of the new box culvert will be 10 feet wide, 4 feet .high and 75 feet long. The new box culvert is designed for the pipelines to remain in their existing location (see Figures 4 and 5). Invert elevation of the box culvert cutlet would be 6.6 feet (NAVD) to tie into the existing SW 23rd Street channel; invert elevation of the outlet would be 6.5 feet (NAVD). A channel approximately 10 feet long with 1.5:1 side slopes would be excavated in the upland area to connect the box culvert outlet with the existing SW 23rd Street channel. The inlet and outlet of the box culvert would be rock-lined to maintain the structural integrity of the culvert to channel connection. The remaining portions of the 1.5:1 side slopes of the channel would be revegetated with native low growing wetland shrubs. DRAFT, July 11, 1997 PAGE 3 JUL711-97 FRI 01 :50 PH FAX NO, P. 06 (4) Install a new 30-inch culvert parallel to and east of Lind Avenue to connect a small channel north of the SW 23rd Street access road to the SW 23rd Street channel, south of the access road to restore drainage system function. Because of the existing non-functioning 30-inch culvert that crosses bind Avenue north of the SW 23rd Street channel, a new culvert would be installed to route flow from the small channel located north of SW 23rd Street and cast of Lind Avenue to the SW 23rd Street channel. Development of the property north of the channel and west of Lind Avenue plugged the existing culvert approximately 10 years ago. Because this channel currently has no drainage outlet along Lind Avenue or SW 23rd Street, surface water no longer drains but collects in the channel and has created wetland conditions and flooding problems on the property north of SW 23rd Street and east of Lind Avenue. Installation of a new culvert would maintain the drainage system that was in place before the culvert was plugged. �oCf a1 u3P The new culvert would be a 30-inch diameter culvert with the inlet cc g the existing 30-inch non-functioning culvert's inlet. The invert elevation of the north end of the new culver , 1.47 feet (NAVD), is equal to the existing non-functioning culvert. The invert e evation of the south end of the new culvert would be 7.7 feet (NAVD), which is approximately 1.2 feet higher than the invert elevation of the existing 9-foot by 14-foot culverts under Und Avenue south of SW 23rd Street. Riprap would be placed at the culvert's outlet to dissipate stormwater runoff entering into the SW 23rd Street channel. See Figures b and 7 for the plan and profile alignment design of the new culvert, (5) Remove sediment from the twin 9-foot by 14-foot culverts under Lind Avenue at SW 23rd Street and immediately upstream and downstream of the culvert openings. This activity is part of the periodic maintenance required to maintain the positive drainage along;this portion of the SW 23rd Street channel. Approximately 2 to 3 feet of sediment has accumulated in the SW 23rd Street channel and at both openings of the twin culverts. A backhoe and/or vacuum truck positioned on the SW 23rd Street access road would remove this sediment to the invert elevation of the culverts, The sediment removal would occur within approximately 20 feet of the culvert opening on the east side of Lind Avenue, and within the pool area on the west side of Lind Avenue. Sediment would be disposed on an upland site. (Sedinierit within the culverts would be removed using a combination of hurnan assisted shoveling and a vacuum device to bring the sediment to a truck/storage container on the access road.) Impacts on Project Elements 1-5: Cumulative impacts on wetland: from the proposed a activities are as €ollows- DRA R-, July 11, 1997 PAGE 5 JUL711-97 FRI 01 :51 PM FAX N0, P. 08 vegetation removed to construct the channel. Approximately 185 square feet of wetland and channel bottom would be created from construction of the new channel. No impacts to fish are expected to occur. Fish have not been observed in the channel and current use would he limited by the downstream beaver dam. The proposed project replaces culverts that are a barrier to fish with a fish passable culvert. Downstream. water quality would be protected during constniction by placement of sedimentation fences and rerouting surface flows back into the channel downstream of the construction area via a bypass pipe. A series of straw bales would be placed in the channel to contain sediment from the water in in the bypass pipe. The bales would be removed after all construction is complete. Sediment would be removed if large enough quantities accumulated behind the bales. Temporary dewatering of the area to allow for construction of the box culvert and other project elements could result in pumping of turbid water through the bypass system and into the SW 23rd Street channel. The straw bales in the channel would trap any sediment before reaching Springbrook Creek. Existing water elevations in Wetland W-8N during storm events are cuased by the undersized culverts under the Olympic Pipeline crossing. Hydraulic modeling of surface water elevations within the SW 23rd Street channel indicate that the surface water elevations for a 2 year storm would be reduced by 2 feet by the culvert replacement. This is not expected to impact wetland acreage associated with wetland W-8N because (1) surface water connections between the channel and wetland W-8N would still occur and surface water would continue to inundate wetland W-8N, (2) base flow within the channel is not expected to change, and (3) two-year storm overflows into the wetland are relatively short in duration (less than one day) according to hydrologic/hydraulic simulation. The decrease in the maximum water Ievels during storm events is not expected to significantly change the wetland vegetation. Some herbaceous species may decrease (e.g., cattail and yellow flag) whereas other species may increase (e.g., sedges and rushes). Willow and spirea are species adapted to water level fluctuations and are expected to continue to dominate the wetland. (2) Remove the abandoned beaver dam at the mouth of the SW 23rd Street channel as it enters Springbrook Creek west of Lind Avenue and south of the SW 23rd Street /raccess road.a.,a isde---vFs /-,1-1 te..,&v4- dtiri'r f,,) e4! e01-��.h 4.J L /-i 7G�WQ.�/1 SPrr,� pn.o� �iec� /,J Removal of the small beaver dam which has deteriorated to a loose. assemblage of sticks will not require any removal of wetland vegetation.

The beaver dam can be removed with DRAFT', July 11, 1997 PAGE 7 JUL-11-97 FRI 01 :52 PH FAX NO, P. 10 and strawbales discussed under element No. 1 would be in place to reduce sedimentation impacts to the water in the channel. Any wetland area temporarily disturbed from construction activities would be revegetated with shrubs common to the area. Placement of the new culvert would restore the drainage system north of the SW 23rd Street access road. Late spring surface water elevations in the: channel within wetland W-7S could be reduced approximately 1.8 feet, (This is based on the difference of existing water elevations in the wetland and water elevations associated with the proposed project in place.) Although the installation of the new culvert would reduce the frequency and depth of inundation during storm events along the channel, the scrub-shrub vegetation associated with this wetland is not expected to change, Species such as willow, reed canarygrass, and spirea growing in the wetland, and outside of the channel within the wetland, are tolerant of changes in water levels and are expected to adapt to the new hydrologic regime. High ground water within 18-24 inches of the surface of the wetland would continue to support the growth of scrub-shrub vegetation. Additional scrub-shrub vegetation may establish within the channel from the reduced water levels. (5) Remove sediment from the twin 9-foot by 14-foot culverts tinder Lind Avenue at SW 23rd Street and immediately upstream and downstream of the culvert openings. Sediment that supports approximately 970 square feet (0.02 acre) of emergent vegetation (American brooklime) would be removed from the pool downstream of the culvert openings. Wetland vegetation would not be affected in the area upstream of the culverts; sediment would be removed from an unvegetated area of approximately 590 square feet upstream of the culverts within the wetland. Wetland vegetation would not be affected in this small area where plants have not yet established. Protection of water quality downstream of the sediment removal area would be accomplished by working during low flows and bypassing; the flows around the work area. Sediment samples will be taken before construction to evaluate sediment quality and disposal requirements. Straw bales placed in the channel would be in place to trap sediment and soil pollutants before reaching Sprinbbrook Creek. 9.
