The regulations which govern our permit program contain a series of Nationwide Permits (NWPs). Each NWP authorizes a specific category of work,provided certain conditions are met. The NWP 18 (Federal Register, December 13, 1996, Vol. 61,No. 241 and/or March 9, 2000, Vol. 65,No. 47) authorizes "Minor Discharges." The entire text of NWP 18 including its specific regional conditions is enclosed. The NWP 18 authorizes the above-described proposed project. The work must be performed as depicted on the enclosed drawings and in accordance with the enclosed general conditions and the special conditions listed below in order to remain authorized by the NWP. Endangered Species Act Compliance: I have completed the necessary coordination under Section 7 of the Endangered Species Act (ESA). I have added the following special conditions to your permit: a. You must implement the Endangered Species Act (ESA)requirements and/or agreements set forth in the Renton Sunnydale Downstream Storm System Replacement Project, dated October 2000, in its entirety. The U.S. Fish and Wildlife Service (USFWS) concurred with a finding of"may affect, not likely to adversely affect"based on this document on August 30, 2001 (USFWS Reference Number 1-3-01-I-1459). The National Marine Fisheries a -2- Service (NMFS) concurred with a finding of"may affect, not likely to adversely affect"based on this document on January 14, 2002 (NMFS Reference Number WSB-01-163). Both agencies will be informed of this permit issuance and will enforce any known violations of the commitments made in this document pursuant to the ESA. b. In order to protect Chinook salmon and bull trout, in-water work shall only occur during the period of July 1 through August 31 of any year. No in-water work shall occur from September 1 through June 30 of the following year. The State of Washington has partially denied 401 Water Quality Certification(WQC) and Coastal Zone Management(CZM) Consistency Response under certain conditions. You need to check with the Washington State Department of Ecology(State) to determine any further 401 WQC and CZM requirements. Please telephone or send your plans to the following address prior to starting work: Washington State Department of Ecology Northwest Regional Office 3190— 160`h Avenue Southeast Bellevue, Washington 98008-5452 Telephone (425) 649-7145 You must send us a copy of the individual 401 WQC and CZM Consistency Response authorizations for our file.

ASSISTANCE BY: Entranco SHEET: 6 of DATUM: City of Renton DRAWN BY: CLS DATE: September 2000 NATIONWIDE PERMIT/CORPS SEATTLE DISTRICT/7 JUNE 2000 h CONDITIONS FOR NATIONWIDE PERMITS National Conditions. The following general conditions must be followed in order for any authorization by an NWP to be valid: 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. Soil Erosion and Sediment Controls. Appropriate soil erosion and sediment 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. Culverts placed in streams must be installed to maintain low flow conditions. 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 or by the State or tribe in its Section 401 water quality certification and Coastal Zone Management Act consistency determination. 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 affect the Wild and Scenic River designation, or study status. Information on Wild and Scenic Rivers may be obtained from the 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. 1 NATIONWIDE PERMIT/CORPS SEATTLE DISTRICT/7 JUNE 2000 9. Water Quality. (a) In certain States and tribal lands an individual 401 water quality certification must be obtained or waived (See 33 CFR 330.4(c)). (b) For NWPs 12, 14, 17, 18, 32, 39, 40, 42, 43, and 44, where the State or tribal 401 certification (either generically or individually) does not require or approve a water quality management plan, the permittee must include design criteria and techniques that will ensure that the authorized work does not result in more than minimal degradation of water quality. An important component of a water quality management plan includes.stormwater management that minimizes.degradation of the downstream aquatic system, including water quality. Refer to General Condition 21 for stormwater management requirements. Another important component of a water quality management plan is the establishment and maintenance of vegetated buffers next to open waters, including streams. Refer to General Condition 19 for vegetated buffer requirements for the NWPs. 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 will destroy or adversely modify the critical habitat of such species. Non-federal permittees shall notify the District Engineer if any listed species or designated critical habitat might be affected or is in the vicinity of the project, or is located in the designated critical habitat 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. For activities that may affect Federally-listed endangered or threatened species or designated critical habitat, the notification must include the name(s) of the endangered or threatened species that may be affected by the proposed work or that utilize the designated critical habitat that may be affected by the proposed work. As a result of formal or informal consultation with the FWS or NMFS, the District Engineer may add species-specific regional endangered species conditions to the NWPs. (b) Authorization of an activity by a nationwide permit does not authorize the "take" of a threatened or endangered species as defined under the 2 NATIONWIDE PERMIT/CORPS SEATTLE DISTRICT/7 JUNE 2000 Federal Endangered Species Act. In the absence of separate authorization (e.g., an ESA Section 10 Permit, a Biological Opinion with "incidental take" provisions, etc.) from the U.S. Fish and Wildlife Service or the National Marine Fisheries Service, both lethal and non- lethal "takes" of protected species are in violation of the Endangered Species Act. Information on the location of threatened and endangered species and their critical habitat can be obtained directly from the offices of the U.S. Fish and Wildlife Service and National Marine Fisheries Service or their world wide web pages at http://www.fws.gov/r9endspp/endspp.html and http://www.nfms.gov/prot_res/esahome.htm1, respectively. 12. Historic Properties. No activity which may affect historic properties listed, or eligible for listing, in the National Register of Historic Places is authorized, until the DE has complied with the provisions of 33 CFR part 325, Appendix C. The prospective permittee must notify the District Engineer if the authorized activity may affect any historic properties listed, determined to be eligible, or which the prospective permittee has reason to believe may be eligible for listing on the National Register of Historic Places, and shall not begin the activity until notified by the District Engineer that the requirements of the National Historic Preservation Act have been satisfied and that the activity is authorized. Information on the location and existence of historic resources can be obtained from the State Historic Preservation Office and the National Register of Historic Places (see 33 CFR 330.4(g)). For activities that may affect historic properties listed in, or eligible for listing in, the National Register of Historic Places, the notification must state which historic property may be affected by the proposed work or include a vicinity map indicating the location of the historic property. 13. Notification. (a) Timing: Where required by the terms of the NWP, the prospective permittee must notify the District Engineer with a preconstruction notification (PCN) as early as possible. The District Engineer must determine if the PCN is complete within 30 days of the date of receipt and can request the additional information necessary to make the PCN complete only once. However, if the prospective permittee does not provide all of the requested information, then the District Engineer will notify the prospective permittee that the PCN is still incomplete and the PCN review process will not commence until all of the requested information has been received by the District Engineer. The prospective permittee shall not begin the activity: (1) Until notified in writing by the District Engineer that the activity may proceed under the NWP with any special conditions imposed by the District or Division Engineer; or 3 NATIONWIDE PERMIT/CORPS SEATTLE DISTRICT/7 JUNE 2000 (2) If notified in writing by the District or Division Engineer that an individual permit is required; or (3) Unless 45 days have passed from the District Engineer's receipt of the complete notification and the prospective permittee has not received written notice from the District or Division Engineer. 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 permit(s), 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 7, 12, 14, 18, 21, 34, 38, 39, 40, 41, 42, and 43, the PCN must also include a delineation of affected special aquatic sites, including wetlands, vegetated shallows (e.g., submerged aquatic vegetation, seagrass beds), and riffle and pool complexes (see paragraph 13(f)); (5) For NWP 7, Outfall Structures and Maintenance, the PCN must include information regarding the original design capacities and configurations of those areas of the facility where maintenance dredging or excavation is proposed.

(9) For NWP 29, Single-Family Housing, the PCN must also include: (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 NWP, parcels of land measuring '/4 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 '/4 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, co-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; (10) For NWP 31, Maintenance of Existing Flood Control Projects, the prospective permittee must either notify the District Engineer with a PCN prior to each maintenance activity or submit a five year (or less) maintenance plan. In addition, the PCN must include all of the following: (i) Sufficient baseline information so as to identify the approved channel depths and configurations and existing facilities. Minor deviations are authorized, provided the approved flood control protection or drainage is not increased; (ii) A delineation of any affected special aquatic sites, including wetlands; and, (iii) Location of the dredged material disposal site. 5 NATIONWIDE PERMIT/CORPS SEATTLE DISTRICT/7 JUNE 2000 (11) For NWP 33, Temporary Construction, Access, and Dewatering, the PCN must also include a restoration plan of reasonable measures to avoid and minimize adverse effects to aquatic resources. (12) For NWPs 39, 43, and 44, the PCN must also include a written statement to the District Engineer explaining how avoidance and minimization of losses of waters of the United States were achieved on the project site. (13) For NWP 39, Residential, Commercial, and Institutional Developments, and.NWP 42, Recreational Facilities, the PCN must include a compensatory mitigation proposal that offsets unavoidable losses of waters of the United States or justification explaining why compensatory mitigation should not be required. (14) For NWP 40, Agricultural Activities, the PCN must include a compensatory mitigation proposal to offset losses of waters of the United States. (15) For NWP 43, Stormwater Management Facilities, the PCN must include, for the construction of new stormwater management facilities, a maintenance plan (in accordance with State and local requirements, if applicable) and a compensatory mitigation proposal to offset losses of waters of the United States. (16) For NWP 44, Mining Activities, the PCN must include a description of all waters of the United States adversely affected by the project, a description of measures taken to minimize adverse effects to waters of the United States, a description of measures taken to comply with the criteria of the NWP, and a reclamation plan (for aggregate mining activities in isolated waters and non- tidal wetlands adjacent to headwaters and any hard rock/mineral mining activities). (17) For activities that may adversely affect Federally-listed endangered or threatened species, the PCN must include the name(s) of those endangered or threatened species that may be affected by the proposed work or utilize the designated critical habitat that may be affected by the proposed work. (18) For activities that may affect historic properties listed in, or eligible for listing in, the National Register of Historic Places, the PCN must state which historic property may be affected by the proposed work or include a vicinity map indicating the location of the historic property. 6 NATIONWIDE PERMIT/CORPS SEATTLE DISTRICT/7 JUNE 2000 (19) For NWPs 12, 14, 29, 39, 40, 42, 43, and 44, where the proposed work involves discharges of dredged or fill material into waters of the United States resulting in permanent, above-grade fills within 100-year floodplains (as identified on FEMA's Flood Insurance Rate Maps or FEMA-approved local floodplain maps), the notification must include documentation demonstrating that the proposed work complies with the appropriate FEMA or FEMA- approved local floodplain construction requirements. (c) Form of Notification: The standard individual permit application form (Form ENG 4345) may be used as the notification but must clearly indicate that it is a PCN and must include all of the information required in (b) (1)-(19) of General Condition 13. A letter containing the requisite information may also be used. (d) District Engineer's Decision: In reviewing the PCN 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 PCN to expedite the process and the District Engineer will consider any proposed compensatory mitigation the applicant has included in the proposal in determining whether the net adverse environmental effects to the aquatic environment 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 on the aquatic environment are minimal, the District Engineer will notify the permittee and include any conditions the District Engineer deems necessary. Any compensatory mitigation proposal must be approved by the District Engineer prior to commencing work. If the prospective permittee is required to submit a compensatory mitigation proposal with the PCN, the proposal may be either conceptual or detailed. If the prospective permittee elects to submit a compensatory mitigation plan with the PCN, the District Engineer will expeditiously review the proposed compensatory mitigation plan. The District Engineer must review the plan within 45 days of receiving a complete PCN and determine whether the conceptual or specific proposed mitigation would ensure no more than minimal adverse effects on the aquatic environment. If the net adverse effects of the project on the aquatic environment (after consideration of the compensatory 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. 7 NATIONWIDE PERMIT/CORPS SEATTLE DISTRICT/7 JUNE 2000 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; (2) that the project is authorized under the NWP subject to the applicant's submission of a mitigation proposal that would reduce the adverse effects on the aquatic environment to the minimal level, or (3) that the project is authorized under the NWP with specific modifications or conditions. Where the District Engineer determines that mitigation is required in order to ensure no more than minimal adverse effects on the aquatic environment, the activity will be authorized within the 45-day PCN period, including the necessary conceptual or specific mitigation or a requirement that the applicant submit a mitigation proposal that would reduce the adverse effects on the aquatic environment to the minimal level. When conceptual mitigation is included, or a mitigation plan is required under item (2) above, no work in waters of the United States will occur until the District Engineer has approved a specific mitigation plan. (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 effects on the aquatic environment to a minimal level. For activities requiring notification to the District Engineer that result in the loss of greater than '/2 acre of waters of the United States, the District Engineer will, upon receipt of a notification, provide immediately (e.g., via facsimile transmission, overnight mail, or other expeditious manner), a copy to the appropriate offices of the Fish and Wildlife Service, State natural resource or water quality agency, EPA, State Historic Preservation Officer (SHPO), and, if appropriate, the National Marine Fisheries Service. With the exception of NWP 37, these agencies will then have 10 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 15 calendar days before making a decision on the notification. The 8 NATIONWIDE PERMIT/CORPS SEATTLE DISTRICT/7 JUNE 2000 District Engineer will fully consider agency comments received within the specified time frame, but will provide no response to the resource agency, except as provided below. The District Engineer will indicate in the administrative record associated with each notification that the resource agencies' concerns were considered. As required by Section 305(b)(4)(B) of the Magnuson-Stevens Fishery Conservation and Management Act, the District Engineer will provide a response to National Marine Fisheries Service within 30 days of receipt of any Essential Fish Habitat conservation recommendations. Applicants are encouraged to provide the Corps multiple copies of notifications to expedite agency notification. (f) Wetlands Delineations: Wetland delineations must be prepared in accordance with the current method required by the Corps. For NWP 29 see paragraph (b)(9)(iii) for parcels less than '/4 acre 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 45-day period will not start until the wetland delineation has been completed and submitted to the Corps, where appropriate. 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. The certification 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, and (c) The signature of the permittee certifying the completion of the work and mitigation. 15. Use of Multiple Nationwide Permits. The use of more than one NWP for a single and complete project is prohibited, except when the acreage loss of waters of the United States authorized by the NWPs does not exceed the acreage limit of the NWP with the highest specified acreage limit. For example, if a road crossing over tidal waters is constructed under NWP 14, with associated bank stabilization authorized by NWP 13, the maximum acreage loss of waters of the United States for the total project cannot exceed 1/3 acre. 9 NATIONWIDE PERMIT/CORPS SEATTLE DISTRICT/7 JUNE 2000 16. Water Supply Intakes. No activity, including structures and work in . navigable waters of the United States or discharges of dredged or fill material, may occur in the proximity of a public water supply intake except where the activity is for repair of the public water supply intake structures or adjacent bank stabilization. 17. Shellfish Beds. No activity, including structures and work in navigable waters of the United States or discharges of dredged or fill material, may occur in areas of concentrated shellfish populations, unless the activity is directly related to a shellfish harvesting activity authorized by NWP 4. 18. Suitable Material.. No activity, including structures-and work-in navigable waters of the United States or discharges of dredged or fill material, may consist of unsuitable material (e.g., trash, debris, car bodies, asphalt, etc.) and material used for construction or discharged must be free from toxic pollutants in toxic amounts (see Section 307 of the Clean Water Act). 19. Mitigation. The project must be designed and constructed to avoid and minimize adverse effects to waters of the United States to the maximum extent practicable at the project site (i.e., on site). Mitigation will be required when necessary to ensure that the adverse effects to the aquatic environment are minimal. The District Engineer will consider the factors discussed below when determining the acceptability of appropriate and practicable mitigation necessary to offset adverse effects on the aquatic environment that are more than minimal. (a) Compensatory mitigation at a minimum 1:1 ratio will be required for all wetland impacts requiring a PCN. Consistent with National policy, the District Engineer will establish a preference for restoration of wetlands to meet the minimum compensatory mitigation ratio, with preservation used only in exceptional circumstances. (b) 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. Examples of mitigation that may be appropriate and practicable include, but are not limited to: reducing the size of the project; establishing and maintaining wetland or upland vegetated buffers to protect open waters such as streams; and replacing losses of aquatic resource functions and values by creating, restoring, enhancing, or preserving similar functions and values, preferably in the same watershed; (c) The District Engineer will require restoration, creation, enhancement, or preservation of other aquatic resources in order to offset the authorized impacts to the extent necessary to ensure that the adverse effects on the aquatic environment are minimal. An important element 10 NATIONWIDE PERMIT/CORPS SEATTLE DISTRICT/7 JUNE 2000 of any compensatory mitigation plan for projects in or near streams or other open waters is the establishment and maintenance, to the maximum extent practicable, of vegetated buffers next to open waters on the project site. The vegetated buffer should consist of native species. The District Engineer will determine the appropriate width of the vegetated buffer and in which cases it will be required. Normally, the vegetated buffer will be 25 to 50 feet wide on each side of the stream, but the District Engineer may require wider vegetated buffers to address documented water quality concerns. If there are open waters on the project site and the District Engineer requires compensatory mitigation for wetland impacts to ensure that the net adverse effects on the aquatic environment are minimal, any vegetated buffer will comprise no more than 1/3 of the remaining compensatory mitigation acreage after the permanently filled wetlands have been replaced on a one-to-one acreage basis. In addition, compensatory mitigation must address adverse effects on wetland functions and values and cannot be used to offset the acreage of wetland losses that would occur in order to meet the acreage limits of some of the NWPs (e.g., for NWP 39, '/4 acre of wetlands cannot be created to change a '/2 acre loss of wetlands to a '/4 acre loss, however, '/z acre of created wetlands can be used to reduce the impacts of a 1/3 acre loss of wetlands). If the prospective permittee is required to submit a compensatory mitigation proposal with the PCN, the proposal may be either conceptual or detailed. (d) To the extent appropriate, permittees should consider mitigation banking and other appropriate forms of compensatory mitigation. If the District Engineer determines that compensatory mitigation is necessary to offset losses of waters of the United States and ensure that the net adverse effects of the authorized work on the aquatic environment are minimal, consolidated mitigation approaches, such as mitigation banks, will be the preferred method of providing compensatory mitigation, unless the District Engineer determines that activity-specific compensatory mitigation is more appropriate, based on which is best for the aquatic environment. These types of mitigation are preferred because they involve larger blocks of protected aquatic environment, are more likely to meet the mitigation goals, and are more easily checked for compliance. If a mitigation bank or other consolidated mitigation approach is not available in the watershed, the District Engineer will consider other appropriate forms of compensatory mitigation to offset the losses of waters of the United States to ensure that the net adverse effects of the authorized work on the aquatic environment are minimal. 11 NATIONWIDE PERMIT/CORPS SEATTLE DISTRICT/7 JUNE 2000 20. Spawning Areas. Activities, including structures and work in navigable waters of the United States or discharges of dredged or fill material, in spawning areas during spawning seasons must be avoided to the maximum extent practicable. Activities that result in the physical destruction (e.g., excavate, fill, or smother downstream by substantial turbidity) of an important spawning area are not authorized. 21. Management of Water Flows. To the maximum extent practicable, the activity must be designed to maintain preconstruction downstream flow conditions (e.g., location, capacity, and flow rates). Furthermore, the activity must not permanently restrict or impede the passage of normal or expected high flows.(unless the primary purpose of the fill is to impound waters) and the structure or discharge of dredged or fill material must withstand expected high flows. The activity must, to the maximum extent practicable, provide for retaining excess flows from the site, provide for maintaining surface flow rates from the site similar to preconstruction conditions, and must not increase water flows from the project site, relocate water, or redirect water flow beyond preconstruction conditions. In addition, the activity must, to the maximum extent practicable, reduce adverse effects such as flooding or erosion downstream and upstream of the project site, unless the activity is part of a larger system designed to manage water flows. 22. Adverse Effects From Impoundments. If the activity, including structures and work in navigable waters of the United States or discharge of dredged or fill material, creates an impoundment of water, adverse effects on the aquatic system caused by the accelerated passage of water and/or the restriction of its flow shall be minimized to the maximum extent practicable. 23. Waterfowl Breeding Areas. Activities, including structures and work in navigable waters of the United States or discharges of dredged or fill material, into breeding areas for migratory waterfowl must be avoided to the maximum extent practicable. 24. Removal of Temporary Fills. Any temporary fills must be removed in their entirety and the affected areas returned to their preexisting elevation. 25. Designated Critical Resource Waters. Critical resource waters include. NOAA-designated marine sanctuaries, National Estuarine Research Reserves, National Wild and Scenic Rivers, critical habitat for Federally listed threatened and endangered species, coral reefs, State natural heritage sites, and outstanding national resource waters or other waters officially designated by a State as having particular environmental or ecological significance and identified by the District Engineer after notice and opportunity for public comment. The District Engineer may also 12 NATIONWIDE PERMIT/CORPS SEATTLE DISTRICT/7 JUNE 2000 designate additional critical resource waters after notice and opportunity for comment. (a) Except as noted below, discharges of dredged or fill material into waters of the United States are not authorized by NWPs 7, 12, 14, 16, 17, 21, 29, 31, 35, 39, 40, 42, 43, and 44 for any activity within, or directly affecting, critical resource waters, including wetlands adjacent to such waters. Discharges of dredged or fill materials into waters of the United States may be authorized by the above NWPs in National Wild and Scenic Rivers if the activity complies with General Condition 7. Further, such discharges may be authorized in designated critical habitat for Federally listed threatened or endangered species if the activity complies with General Condition 11 and the U.S. Fish and Wildlife Service or the National Marine Fisheries Service has concurred in a determination of compliance with this condition. (b) For NWPs 3, 8, 10, 13, 15, 18, 19, 22, 23, 25, 27, 28, 30, 33, 34, 36, 37, and 38, notification is required in accordance with General Condition 13, for any activity proposed in the designated critical resource waters including wetlands adjacent to those waters. The District Engineer may authorize activities under these NWPs only after he determines that the impacts to the critical resource waters will be no more than minimal. 26. Fills Within 100-Year Floodplains. For purposes of this general condition, 100-year floodplains will be identified through the Federal Emergency Management Agency's (FEMA) Flood Insurance Rate Maps or FEMA- approved local floodplain maps. (a) Discharges Below Headwaters. Discharges of dredged or fill material into waters of the United States resulting in permanent, above-grade fills within the 100-year floodplain at or below the point on a stream where the average annual flow is five cubic feet per second (i.e., below headwaters) are not authorized by NWPs 29, 39, 40, 42, 43, and 44. For NWPs 12 and 14, the prospective permittee must notify the District Engineer in accordance with General Condition 13 and the notification must include documentation that any permanent, above-grade fills in waters of the United States within the 100-year floodplain below headwaters comply with FEMA or FEMA-approved local floodplain construction requirements. (b) Discharges in Headwaters (i.e., above the point on a stream where the average annual flow is five cubic feet per second). 13 NATIONWIDE PERMIT/CORPS SEATTLE DISTRICT/7 JUNE 2000 (1) Flood Fringe. Discharges of dredged or fill material into waters of the United States resulting in permanent, above-grade fills within the flood fringe of the 100-year floodplain of headwaters are not authorized by NWPs 12, 14, 29, 39, 40, 42, 43, and 44, unless the prospective permittee notifies the District Engineer in accordance with General Condition 13. The notification must include documentation that such discharges comply with FEMA or FEMA- approved local floodplain construction requirements. (2) Floodway. Discharges of dredged or fill material into waters of the United States resulting in permanent, above-grade fills within the floodway of the 100-year floodplain of headwaters are not authorized by NWPs 29, 39, 40, 42, 43, and 44. For NWPs 12 and 14, the permittee must notify the District Engineer in accordance with General Condition 13 and the notification must include documentation that any permanent, above grade fills proposed in the floodway comply with FEMA or FEMA-approved local floodplain construction requirements. Section 10 Only Condition 1. Removal. Relocation or Other Alteration to Structures. The permitee understands and agrees that, if future operations by the United States requires the removal, relocation, or other alteration, of the structure or work herein authorized, or if, in the opinion of the Secretary of the Army or his authorized representative, said structure or work shall cause unreasonable obstruction to the free navigation of the navigable waters, the permittee will be required, upon due notice from the Corps of Engineers, to remove, relocate, or alter the structural work or obstructions caused thereby, without expense to the United States. No claim shall be made against the United States on account of any such removal or alteration. Special Condition 1. Access. You must allow representatives from this office to inspect the authorized activity at any time deemed necessary to ensure that it is being or has been accomplished in accordance with the terms and conditions of your permit. 14 NATIONWIDE PERMIT/CORPS SEATTLE DISTRICT/7 JUNE 2000 Corps Regional General Conditions 1.

(h) Liability: Any 401 Certification issued for projects or activities authorized under NWPs does not absolve the applicant from liability for contamination occurring as a result of construction or operations and for subsequent cleanup of surface waters or sediments. EPA 1. Soil Erosion and Sediment Controls. 401 Certification determination is based on the project or activity meeting established turbidity levels. EPA will be using as guidance, the State water quality standards [WAC 173- 201A-110(3)]. Projects or activities that are expected to exceed these levels or that do exceed these levels will require individual 401 Certification. The water quality standards allow for short-term turbidity exceedances after all necessary Best Management Practices have been implemented (e.g., properly placed and maintained filter fences, hay bales and/or other erosion control devices, adequate detention of runoff to prevent turbid water from flowing off-site, providing a vegetated buffer between the activity and open water, etc.), and only up to the following limits: (a) Up to 100 feet downstream from the activity in waters flowing up to 10 cfs (cubic feet per second) at the time of construction; (b) Up to 200 feet downstream from the activity in waters flowing between 10 cfs to 100 cfs at the time of construction; or (c) Up to 300 feet downstream from the activity in waters flowing above 100 cfs at the time of construction. 2. Compliance with Stormwater Provisions. 401 Certification of projects and activities authorized under NWP permits will use the applicable provisions of the most current Ecology-approved version of the Puget Sound Stormwater Manual, or the Washington State Department of Transportation Highway Runoff Manual on highway projects as guidance to meet water quality standards. 3. Compliance with requirements of the National Pollutant Discharge Elimination System (NPDES). For projects and activities requiring coverage under an NPDES permit, certification is based on compliance with the requirements of that permit. Projects and activities that are not in 24 } NATIONWIDE PERMIT/CORPS SEATTLE DISTRICT/7 JUNE 2000 compliance with NPDES requirements will require individual 401 Certification. 4. Projects or Activities Discharging to Impaired Waters. Projects or activities that will discharge to a waterbody on the state's list of impaired waterbodies (the 303(d) list) require individual 401 Certification if the discharge may result in further exceedances of the 303(d)-listed contaminant or will result in further impairment. The current list of 303(d)- listed waterbodies is available on Ecology's web site at http://www.wa.gov/ecology or by contacting Ecology's Federal Permits staff. For projects or activities that will discharge to a 303(d)-listed waterbody that does not have an approved Total Maximum Daily Load (TMDL), the applicant must provide documentation for EPA approval showing that the discharge will not result in further exceedances of the listed contaminant or impairment. For projects or activities that will discharge to a 303(d)-listed waterbody that does have an approved TMDL, the applicant must provide documentation for EPA approval showing that the discharge is within the limits established in the TMDL. EPA may issue 401 Certification determination for projects or activities that would result in further exceedances or impairment if mitigation is provided that would result in a net decrease in listed contaminants or less impairment in the waterbody. This determination would be made during individual 401 review. 5. Notification. For projects that will require individual 401 certification determination, applicants must provide EPA with the same documentation provided to the Corps (per Corps National General Condition 13), including when applicable: (a) Delineation of special aquatic sites, including wetlands.

All erosion and sediment facilities shall be maintained in a satisfactory condition until such time that clearing and/or construction is completed and potential for on—site erosion has passed. The implementation, maintenance, replacement and additions to erosion/sedimentotion control systems shall be the responsibility of the contractor. 3) The erosion and sedimentation control systems depicted on these plan sheets are intended to be minimum requirements to meet anticipated site conditions. As construction progresses and unexpected or seasonal conditions dictate, the contractor shall anticipate that more erosion and sedimentation control facilities will be necessary to insure complete siltation control on the proposed site. During the course of construction, it shall be the obligation and responsibility of the contractor to address any new conditions that may be created by his activities and to provide additional facilities, over and above minimum requirements, as may be needed to protect adjacent properties and water quality of the receiving drainage system. 4) During the time period of November 1 through March 31, all project disturbed soil areas greater than 5,000 square feet, that are to be left unworked for more than twelve (12) hours, shall be covered by mulch, sodding, or plastic covering. 5) In any area which has been stripped of vegetation and where no further work is anticipated for a period of 30 days or more, all disturbed areas must be immediately stabilized with mulching, grass planting or other approved erosion control treatment applicable to the time of year in question. Grass seeding alone will be acceptable only during the months of April through September inclusive. Hydroseeding may proceed, however, whenever it is in the interest of the contractor, but must be augmented with mulching, netting, or other treatment approved by the City of Renton, outside the specified time period. 6) Issuance of the Building or Construction Permit by the City of Renton does not relieve the contractor of the continuing legal obligation and/or liability connected with storm water disposition. Further, the City of Renton does not accept any obligation for the proper functioning and maintenance of the system provided during construction. 7) The contractor shall make every effort to remove only those trees and vegetation necessary to construct the pipeline PURPOSE: PROJECT TITLE: PROPOSED WORK: To reduce erosion and Sunnydale Downstream Replace existing damaged pipe, landslide potential.

DESCRIBE THE CURRENT USE OF THE PROPERTY.AND STRUCTURES EXISTING ON THE PROPERTY. IF ANY PORTION OF THE PROPOSED ACTIVITY IS ALREADY COMPLETED ON THIS PROPERTY,INDICATE MONTH AND YEAR OF COMPLETION. Currently, the site consists of 700 feet of corrugated, aluminum storm pipe and associated manhole structures. The pipe conveys storm runoff from a detention pond located at the top of a hill,down a steep slope, and into a groundwater fed stream at the bottom of the hillside. The site is forested with slopes ranging from 50%-70%. The upper 160 feet of pipe is buried and crosses two underground Olympic Pipeline petroleum pipelines and Bonneville Power Administration overhead power lines. The remaining 540 feet of pipe is anchored above grade and runs approximately 220 feet downhill where it crosses the stream to a manhole structure. The pipe continues from the manhole structure another 320 feet to its outfall. IS THE PROPERTY AGRICULTURAL LAND? ❑YES ONO ARE YOU AN USDA PROGRAM PARTICIPANT? ❑YES ■NO 7a. DESCRIBE THE PROPOSED CONSTRUCTION AND/OR FILL WORK FOR THE PROJECT THAT YOU WANT TO BUILD THAT NEEDS AQUATIC PERMITS: COMPLETE PLANS AND SPECIFICATIONS SHOULD BE PROVIDED FOR ALL WORK WATERWARD OF THE ORDINARY HIGH WATER MARK OR LINE,INCLUDING TYPES OF EQUIPMENT TO BE USED, IF APPLYING FOR A SHORELINE PERMIT,DESCRIBE ALL WORK WITHIN AND BEYOND 200 FEET OF THE ORDINARY HIGH WATER MARK. ATTACH A SEPARATE SHEET IF ADDITIONAL SPACE IS NEEDED. Approximately 800 feet of storm pipe will be constructed within 200 feet of the stream. The majority of the pipe, or approximately 700 feet, will be constructed above ground. The downstream end of the proposed storm system will include an energy dissipator and approximately 100 feet of buried storm pipe adjacent to the stream. To minimize the introduction of sediment into the stream during construction of the outfall structure, a temporary 18-inch pipe will be installed to divert flows around the construction area. The pipe will be laid along the streambed on the opposite the construction, beginning at a point approximately 20 feet upstream of the proposed structure. A sandbag headwall will be constructed by hand around each end of the pipe to act as a dam and direct the stream flow into the pipe. Plastic sheeting will be used on the upstream side of the headwall to minimize infiltration through the sandbags. The bypass pipe will discharge approximately 20 feet downstream of the energy dissipator. Two sandbag check dams will be placed 50 feet apart in the stream downstream of the bypass pipe to provide an additional sediment barrier. The bypass pipe, headwall and check dams will be removed at project completion. 7b. DESCRIBE THE PURPOSE OF THE PROPOSED WORK AND WHY YOU WANT OR NEED TO PERFORM IT AT THE SITE. PLEASE EXPLAIN ANY SPECIFIC NEEDS THAT HAVE INFLUENCED THE DESIGN. The purpose of this project is to replace an existing 700-foot-long metal storm pipe with a new High Density Polyethylene (HDPE) pipe of the same diameter. The project is needed to replace the existing storm system which is aging and in need of extensive repair. As the result of fallen trees, the pipe has been crushed in several locations,reducing its conveyance capacity.The upper 60 feet of the buried portion of pipe is so severely damaged that the pipe joints have separated allowing water to infiltrate into the underlying soil. This condition may potentially weaken the slope causing failure. Due to the proximity of the of the two petroleum pipelines which cross under the storm drain, there is concern that a slope failure in the vicinity of the leaking storm pipe could potentially result in damage to the petroleum lines. Additionally,one of the two manhole structures on the slope has been undermined as a result of undercutting from the adjacent stream and is in danger of collapsing. The proposed storm pipe replacement project will reduce erosion at the pipe outlet and eliminate the chance of landslides occurring at the top of the slope as a result of the leaking pipe. The elimination of intermediate manholes will also reduce the chance of landslides and erosion occurring at other locations as a result of pipe leaks or failure of structures. The majority of the storm system will be relocated further away from the stream(classified as Type 4)than the existing storm system,thus eliminating any stream crossing from the proposed project. 7c. DESCRIBE THE POTENTIAL IMPACTS TO CHARACTERISTIC USES OF THE WATER BODY. THESE USES MAY INCLUDE FISH AND AQUATIC LIFE,WATER QUALITY,WATER SUPPLY, RECREATION,and AESTHETICS. IDENTIFY PROPOSED ACTIONS TO AVOID,MINIMIZE,AND MITIGATE DETRIMENTAL IMPACTS,AND PROVIDE PROPER PROTECTION OF FISH AND AQUATIC LIFE. ATTACH A SEPARATE SHEET IF ADDITIONAL SPACE IS NEEDED. Project construction will involve disturbance of approximately 350 cubic yards of soil. Approximately 20 cubic yards of soil will be removed during construction of the outfall,which may result in some sedimentation in the stream(see enclosed Biological Evaluation dated October 2000). To minimize the impacts to the stream during construction of the riprap outfall,the following measures will be implemented prior to construction: • A temporary headwall and 18-inch bypass pipe will be installed approximately 20 feet upstream of the proposed energy dissipator to divert flows around the construction area. The headwall will be constructed of gravel sandbags and lined with plastic. The bypass pipe will extend through the headwall and run along north side of the channel(opposite the side of Construction)and outfall 15 feet downstream of the construction area. • Installation of silt fence down slope of any soil disturbance • Installation of a series of sandbag checkdams downstream of construction(30-foot spacing) • Construction will occur during the summer when streamflows and precipitation are low • All disturbed areas will be hydroseeded PREPARATION OF DRAWINGS: SEE SAMPLE DRAWINGS AND GUIDANCE FOR COMPLETING THE DRAWINGS.

USEFUL DEFINITIONS The following definitions are presented to help applicants in completing the DARPA. They may not necessarily represent specific language from the laws implemented through JARPA. Ordinary High Water Mark or line means the visible line on the banks where the presence and action of waters are so common as to leave a mark upon the soil or vegetation: Provided, that in any area where the ordinary high water line cannot be found the onSrrary high water line adjoining saltwater shall be the line of mean higher high water and the ordinary high water line adjoining freshwater shall be the elevation of the mean annual flood. Mean Lower Low is the 0.0 tidal elevation, determined by averaging each day's lowest tide at a particular location over a period of 19 years. It is the tidal datum for vertical tidal references in the salt water area. Mean High Water and Mean Higher High Water Tidal Elevations at any specific location can be found in tidal benc:hmark data compiled by the United States Department of Commerce, Environmental Science Services Administration, Coast and Geodetic Survey, dated January 24, 1979. This information can be obtained from the Corps of Engineers at (206) 764-3495. The determination of tidal elevation is obtained by averaging each day's highest tide at a particular location over a period of 19 years, measured from mean lower low water, which equals 0.0 tidal elevation. Shoreiands or shoreland areas means those lands extending landward for two hundred feet in all directions as measured on a horizontal plane from the ordinary high water mark; floodways and contiguous floodplain areas landward two hundred feet from such floodways; and all wetlands and river deltas associated with the streams, lakes, and tidal waters which are subject to the provisions of 90.58 RCW. Shorelines means all water areas of the state, including reservoirs, and their associated wetlands, together with the lands underlying them, except stream segments upstream of the point where mean annual flow is less than 20 cubic feet per second, and lakes iess than 20 acres in size. Wetlands means areas that are inundated or saturated by surface water or ground water at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands generally include swamps, marshes, bogs, and similar areas. Bridge means any structure including pipelines and conveyor belts, which transports traffic or materials across a navigable water. Aquatic Tidelands means the area between the ordinary high tide line and extreme low tide line, unless otherwise established. Aquatic Shorelands means the shore areas of non-tidal navigable lakes or rivers between the ordinary high water line and the line of navigability unless otherwise established. Aquatic Bedlands means the area waterward of and below the line of navigability on non-tidal rivers and lakes, or below the extreme low tide mark in navigable tidal waters, or below the outer harbor line where a harbor has been created.

Box 3755 Seattle, Washington 98124-3755 Re: Endangered Species Act Section 7 Informal Consultation and Magnuson-Stevens Fishery Conservation and Management Act Essential Fish Habitat Consultation for the U.S. Army Corps of Engineers (ACOE), Regulatory Branch, Downstream Storm System Replacement Project, City of Renton, Washington, (ACOE No. 2000-4-01383,NMFS No. WSB-0I-163). Dear Mr. Smith: This correspondence is in response to your request for informal consultation under the Endangered Species Act(ESA). Additionally,this letter serves to meet the requirements for consultation under the Magnusson Stevens Fishery Conservation and Management Act(MSA). Endangered Species Act National Marine Fisheries Service (NMFS)has reviewed the Biological Assessment(BA) dated April 23, 2001, and request for concurrence of the effect determination of"may affect, not likely to adversely affect" for Puget Sound(PS) chinook(Oncorhynchus tshawytscha) and its designated critical habitat. The proposed project by the ACOE, Seattle District Regulatory Branch, is the replacement of an existing 700-foot long, 18-inch corrugated metal stormwater pipe with approximately 800 feet of High-Density Polyethylene (HDPE) 18-inch stormwater pipe. The proposed new stormwater pipe will be installed along a different alignment at the same location. The proposed project's location is SE '/a Section 16, Township 23 North, Range 5 East, City of Renton, King County, Washington. The upper section of the stormwater pipe that is currently buried will be replaced in the existing trench with a minimum one-foot clearance above the existing Olympic Pipeline Company (OPLC)petroleum lines. The remaining section of the pipe will be constructed along a new alignment on the south side of the stream. The proposed new alignment will avoid the steeper portion of the slope and crossing of the unnamed stream that discharges into the Green River. /.TMOgq, G `y Printed on Recycled Paper S MEN Oi � -2- The proposed replacement of the buried section of the pipe will require the use of a backhoe and a dump truck for shoring and excavation of the existing trench. Approximately 16 cubic yards of controlled density fill will be installed in the trench to protect the existing OPLC pipelines. The above ground sections of the proposed new stormwater pipe will be laid from the top of the slope. The pipe segments will be lowered down the slope with cable and fused together. Staging areas will be located on the existing maintenance roads at the top of the hill and along the lower portion of the stream. The proposed construction and maintenance easement of the pipeline will be 15 feet wide. In addition to the above mentioned work, an energy dissipator will be installed at the discharge end of the proposed stormwater pipe. This will help to alleviate the erosion and scouring problem associated with the current discharge, into the unnamed stream from a drop of nearly 4 feet. The proposed new outfall will be relocated approximately 90 feet downstream and will consist of a small amount of rip-rap to absorb the energy from the proposed new outfall. Approximately 20 cubic yards of soil will be removed during outfall construction. In order to prevent impacts from sedimentation during construction,a temporary headwall and 18-inch bypass pipe will be installed upstream of the site to divert flows around the construction site. The headwall will be constructed of gravel sandbags and lined with plastic. The bypass pipe will discharge approximately 15 feet downstream of the construction site. Two sandbag check dams will be placed in the stream downstream of the bypass pipe,approximately 50 feet apart. The proposed bypass pipe, headwall and check dams will be removed upon completion of the project. The proposed project may have the following adverse effects: • There is the potential for deleterious petro-chemical contaminants such as diesel and hydraulic fluids to enter nearby waterways as a result of the proposed construction equipment. • There is the potential for construction-generated sediment to enter the Cedar River that could have the potential to result in temporary and localized increases in turbidity near the outlet of the unnamed stream into the river. This however is expected to be negligible given the various conservation measures proposed for use. • There is the potential for levels of erosion to occur during the proposed construction activities that includes the minor clearing of shrubs,blackberries and grasses. This type of activity could have the potential to further degrade slope stability in the vicinity of the proj ect. As stated in the BA the following conservation measures will be taken to minimize and avoid the above mentioned potential adverse effects of the proposed project: 4. To reduce potential direct impacts due to erosion and sedimentation, construction is scheduled for the summer, the region's typical dry season. -3- 5. To reduce impacts during construction of the outfall and energy dissipator, the stream will be temporarily bypassed around the construction area. 6. To further avoid potential direct impacts through erosion and sedimentation, the extent of vegetated area that will be cleared and graded will be minimized where possible. A Temporary Erosion and Sedimentation Control Plan (TESCP), which includes the installation of sediment fences and other BMP's, will be developed to limit construction-related impacts. 7. A Spill/Pollution Prevention Plan(SPPP)will be implemented to mitigate potential sedimentation and construction-related pollution to the unnamed stream and the Cedar River. 8. Fueling of all construction-related vehicles will be fueled offsite and all hoses and tanks will be inspected daily to ensure that no leaks are present and fixed immediately when deemed appropriate. 9. All materials proposed for use shall be stockpiled at an approved upland site and covered at all times when not in use. 10. All revegetation will be with native plants, shrubs, grasses and soils as well as native soils for the proposed backfilling of excavated trenches. 11. The proposed work will be conducted in an unnamed stream that is inaccessible to salmonids due to man-made barriers. Based on the measures to minimize and avoid(numbers 1 through 7 above),NMFS agrees with your effect determination of"may affect, not likely to adversely affect"for PS chinook and its designated critical habitat. NMFS expects the effects of the proposed actions will be discountable and insignificant. NMFS' concurrence for federally listed salmonid species and their designated critical habitat is contingent upon use of the conservation measures described above. This concludes consultation on these actions in accordance with 50 CFR 402.14(b)(1). The ACOE must reinitiate this ESA consultation: (1) if new information reveals effects of the action that may affect listed species in a way not previously considered; (2) if the action is modified in a manner that causes an effect to the listed species that was not previously considered; or(3) if a new species is listed or critical habitat designated that may be affected by the identified actions. Magnusson Stevens Fishery Conservation and Management Act Federal agencies are required, under §305(b)(2) of the MSA and its implementing regulations (50 CFR 600 Subpart K), to consult with NMFS regarding actions that are authorized, funded, or undertaken by that agency that may adversely affect Essential Fish Habitat(EFH). The MSA (§3) defines EFH as "those waters and substrate necessary to fish for spawning, breeding, -4- feeding, or growth to maturity." If an action would adversely affect EFH,NMFS is required to provide the Federal action agency with EFH conservation recommendations (MSA §305(b)(4)(A)). This consultation is based, in part, on information provided by the Federal action agency and descriptions of EFH for Pacific salmon contained in Appendix A to Amendment 14 to the Pacific Coast Salmon Plan (August 1999) developed by the Pacific Fishery Management Council and approved by the Secretary of Commerce (September 27, 2000). The proposed action and action area are described in the BA and above in this letter. The action area includes habitats which have been designated as EFH for various life stages of chinook and coho salmon(O. kisutch). Because the habitat requirements (i.e., EFH) for the MSA-managed species in the project area are similar to that of the ESA-listed species, and because the conservation measures that the ACOE included as part of the proposed action to address ESA concerns are also adequate to avoid,minimize, or otherwise offset potential adverse effects to designated EFH, conservation recommendations pursuant to MSA(§305(b)(4)(A)) are not necessary. Since NMFS is not providing conservation recommendations at this time,no 30-day response from the ACOE is required (MSA §305(b)(4)(B)). This concludes consultation under the MSA. If the proposed action is modified in a manner that may adversely affect EFH, or if new information becomes available that affects the basis for NMFS' EFH conservation recommendations, the ACOE will need to reinitiate EFH consultation with NMFS in accordance with NMFS implementing regulations for EFH at 50 CFR 600.920(k). If you have any questions, please feel free to contact Christopher Clemons of the Washington Habitat Branch Office at(360) 753-9595. Sincerely, D. Robe Regional dministrator cc: Thomas F.

I also asked him if he though the project would trigger a Department of Ecology 101 Water Quality Certification. He felt the project would trigger a'JO1 but it's up the ecology to make that;call. Phone Conversation 11 Date: 5/17/01 Discussion: Called Deeann Kirkpatrick at National Marine Fisheries Service for status of concurrence letter submitted by the Corps. Left message. Phone Conversation 12 Date: 5/29/01 Discussion: Called Deeann Kirkpatrick. She received BE and letter from Corps on 4/24/01. There are approximately 40-plus project ahead of Sunnydale. She said it would be at least 2 months before the project would get looked at. Phone Conversation 13 Date: 6/19/01 Discussion: Called Alice Kelly at Department of Ecology. She will review project to determine if it will require a 101 Water Quality Cert. k Sunnydale Downstream Storm System Replacement Project Status Update Currently,the project is scheduled to go out to bid in early July,2001. The main obstacle preventing the City from adhering to this deadline are the federal and state permits required for the project, specifically the US Army Corps of Engineers Section 404 and the Department of Ecology 401. These permits must be issued to the City by late June to meet the bid opening date. Federal and state permits are required because the project requires work within the ordinary high water mark of a small stream to construct an energy dissipator oufall. The stream is tributary to the Cedar River. In September of 2000,the City retained the services of a biological consultant to produce a Biological Evaluation(BE) in order to determine whether or not the project would impact any threatened or endangered species downstream of the project area. The consultant completed the BE document in October of 2000 and made a"may affect, but is not likely to adversely affect"determination for Coastal/Puget Sound Bull Trout and Puget Sound ESU Chinook Salmon. This determination allows the federal agencies(US Army Corps of Engineers (Corps),National Marine Fisheries Service(NMFS)and US Fish and Wildlife(USFW))to go through an informal consultation process versus formal consultation which is much more rigorous and time consuming. The Joint Aquatic Resources Permit Application(JARPA)along with the BE was submitted to the agencies in late October of 2000. The approved HPA construction window,which is the period in which all in-stream work must be completed, is June 16 through September 30. The City could elect to construct the in-stream work early in the construction sequence which would permit a later start date and thus delay the bid opening by about three weeks to a month. Under this scenario, the bid advertisement date could occur in late July/early August, giving the City another month to the to obtain permits. If all required permits were received by the latter part of July followed by advertisement in early August, construction of the in-stream work could potentially be completed well in advance of the last day of the fish window, September 30. As a final option, a request could be made to the Washington State Department of Fisheries (WDFW)to extend the HPA deadline another two weeks to the middle of October. In this situation, permits would need to be in hand by mid August at the very latest to allow for in-stream construction by late September. The construction of the energy dissipator could be completed in one to two weeks. The following is a chronology of events to date regarding the Permitting Process: October 23,2000 JARPA(including Biological Evaluation)submitted to the Corps. October 26,2000 Washington State Department of Fish and Wildlife issues Hydraulic Project Approval for project. November 14,2000 City staff called the Corps and determined the project JARPA has been assigned a permit reviewer Jonathan Smith and a reference number 2000-01383 December 13,2000 Called Mr. Smith for permit update.

IF ANY PORTION OF THE PROPOSED ACTIVITY IS ALREADY COMPLETED ON THIS PROPERTY,INDICATE MONTH AND YEAR OF COMPLETION. Currently,the site consists of 700 feet of corrugated aluminum storm pipe and associated manhole structures. The pipe conveys storm runoff from a detention pond located at the top of a hill down a steep slope and into a groundwater fed stream at the bottom of the hillside. The site is heavely forested with slopes ranging from 50%-70%. The upper 100 feet of pipe is buried and crosses two underground Olynpic Pipeline petroleum pipelines and Bonneville Power Administration overhead power lines. The remaining 600 feet of pipe is anchored above grade and runs approximately 250 down hill where it crosses the stream to a manhole structure. The pipe continous from the manhole structure another 200 feet and outfalls. IS THE PROPERTY AGRICULTURAL LAND? ❑YES ONO ARE YOU A USDA PROGRAM PARTICIPANT? ❑YES ■NO 7a. DESCRIBE THE PROPOSED CONSTRUCTION AND/OR FILL WORK FOR THE PROJECT THAT YOU WANT TO BUILD THAT NEEDS AQUATIC PERMITS: COMPLETE PLANS AND SPECIFICATIONS SHOULD BE PROVIDED FOR ALL WORK WATERWARD OF THE ORDINARY HIGH WATER MARK OR LINE,INCLUDING TYPES OF EQUIPMENT TO BE USED. IF APPLYING FOR A SHORELINE PERMIT,DESCRIBE ALL WORK WITHIN AND BEYOND 200 FEET OF THE ORDINARY HIGH WATER MARK. ATTACH A SEPARATE SHEET IF ADDITIONAL SPACE IS NEEDED. The proposed project is to replace the existing storm pipe with a new High-Density Polyethylene(HDPE)pipe of the same diameter. The pipe will buried in the existing trench at the top of the slope and will follow an improved above ground alignment to the bottom. It is anticipated that no clearing will be required other than brush for installation. The new pipe will have no intermediate structues but will have an energy dissipator at the bottom where it outfalls to the stream to control scour. The project will also include removing the existing pipe and structures. The existing pipe will be used as a bypass pipe during construction. 7b. DESCRIBE THE PURPOSE OF THE PROPOSED WORK AND WHY YOU WANT OR NEED TO PERFORM IT AT THE SITE. PLEASE EXPLAIN ANY SPECIFIC NEEDS THAT HAVE INFLUENCED THE DESIGN. The purpose of this project is to replace the existing storm pipe which is aging and in need of extensive repair. As the result of fallen trees,The pipe has been crushed in several location, reducing its conveyance capacity.The upper 60 feet of the buried portion of pipe is so severely damaged that the pipe joints have separated allowing water to infiltrate into the underlying soil. This condition may potentially weaken the slope causing failure. Due to the proximity of the of the two petroleum pipelines which cross under the storm drain,there is concern that a slope failure in the vicinity of the leaking storm pipe could potentially result in damage to the petroleum lines. Additionally,one of the two manhole structures on the slope has been undermined as a result of undercutting from the adjacent stream and is in danger of collapsing. The stream has also scoured out a 5-foot deep hole at the pipe outlet. The proposed storm pipe replacement project will reduce erosion at the pipe outlet and eliminate the chance of landslides occuring at the top of the slope as a result of the leaking pipe. The elimination of intermediate manholes will also reduce the chance of landslides and erosion occuring at other locations as a result of pipe leaks or failure of structures. 7c. DESCRIBE THE POTENTIAL IMPACTS TO CHARACTERISTIC USES OF THE WATER BODY. THESE USES MAY INCLUDE FISH AND AQUATIC LIFE,WATER QUALITY,WATER SUPPLY, RECREATION,and AESTHETICS. IDENTIFY PROPOSED ACTIONS TO AVOID,MINIMIZE,AND MITIGATE DETRIMENTAL IMPACTS,AND PROVIDE PROPER PROTECTION OF FISH AND AQUATIC LIFE. ATTACH A SEPARATE SHEET IF ADDITIONAL SPACE IS NEEDED. Project construction will involve disturbance of approximately 350 cubic yards of soil. Approximately 90 cubic yards of soil will be removed during construction of the outfall which may result in some sedimentation in the stream. bypass pipe will be installed in the creek to To minimize the impacts to the stream,the following measures will be employed during construction: • Installation of silt fence down slope of any soil disturbance. • Installation of sandbag checkdams downstream of construction • Construction will occur during the summer when streamflows and precipitation are low JARPA, Revised 12/98, contact Ecology's Permit Assistance Center for latest version, 360/407-7037 Page 3 of 4 .All disturbed areas will be hydroseeded PREPARATION OF DRAWINGS: SEE SAMPLE DRAWINGS AND GUIDANCE FOR COMPLETING THE DRAWINGS.

USEFUL DEFINITIONS The following definitions are presented to help applicants in completing the JARPA. They may not necessarily represent specific language from the laws implemented through JARPA. Ordinary High Water Mark or Line means the visible line on the banks where the presence and action of waters are so common as to leave a mark upon the soil or vegetation: Provided, that in any area where the ordinary high water line cannot be found the ordinary high water line adjoining saltwater shall be the line of mean higher high water and the ordinary high water line adjoining freshwater shall be the elevation of the mean annual flood. Mean Lower Low is the 0.0 tidal elevation, determined by averaging each day's lowest tide at a particular location over a period of 19 years. It is the tidal datum for vertical tidal references in the salt water area. Mean High Water and Mean Higher High Water Tidal Elevations at any specific location can be found in tidal benchmark data compiled by the United States Department of Commerce, Environmental Science Services Administration, Coast and Geodetic Survey, dated January 24, 1979. This information can be obtained from the Corps of Engineers at(206)764-3495. The determination of tidal elevation is obtained by averaging each day's highest tide at a particular location over a period of 19 years, measured from mean lower low water,which equals 0.0 tidal elevation. Shorelands or shoreland areas means those lands extending landward for two hundred feet in all directions as measured on a horizontal plane from the ordinary high water mark;floodways and contiguous floodplain areas landward two hundred feet from such floodways; and all wetlands and river deltas associated with the streams, lakes, and tidal waters which are subject to the provisions of 90.58 RCW. Shorelines means all water areas of the state, including reservoirs, and their associated wetlands,together with the lands underlying them,except stream segments upstream of the point where mean annual flow is less than 20 cubic feet per second, and lakes less than 20 acres in size. Wetlands means areas that are inundated or saturated by surface water or ground water at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands generally include swamps, marshes, bogs, and similar areas. Bridge means any structure including pipelines and conveyor belts,which transports traffic or materials across a navigable water. Aquatic Tidelands means the area between the ordinary high tide line and extreme low tide line, unless otherwise established. Aquatic Shorelands means the shore areas of non-tidal navigable lakes or rivers between the ordinary high water line and the line of navigability unless otherwise established. Aquatic Bedlands means the area waterward of and below the line of navigability on non-tidal rivers and lakes, or below the extreme low tide mark in navigable tidal waters, or below the outer harbor line where a harbor has been created. Nationwide Permit issued by the Corps of Engineers for projects with minimal impacts. For a complete packet of nationwide permits and application information, contact the Corps Regulatory branch at(206)764-3495.

DESCRIBE THE CURRENT USE OF THE PROPERTY,AND STRUCTURES EXISTING ON THE PROPERTY. IF ANY PORTION OF THE PROPOSED ACTIVITY IS ALREADY COMPLETED ON THIS PROPERTY,INDICATE MONTH AND YEAR OF COMPLETION. Currently, the site consists of 700 feet of corrugated, aluminum storm pipe and associated manhole structures. The pipe conveys storm runoff from a detention pond located at the top of a hill, down a steep slope, and into a groundwater fed stream at the bottom of the hillside. The site is forested with slopes ranging from 50%-70%. The upper 100 feet of pipe is buried and crosses two underground Olympic Pipeline petroleum pipelines and Bonneville Power Administration overhead power lines. The remaining 600 feet of pipe is anchored above grade and runs approximately 250 downhill where it crosses the stream to a manhole structure. The pipe continues from the manhole structure another 200 feet to its outfall. IS THE PROPERTY AGRICULTURAL LAND? ❑YES ONO ARE YOU AN USDA PROGRAM PARTICIPANT? ❑YES ■NO 7a.

II Approximately 800,feet of storm pipe will be constructed within 200}feet of the stream. The majority of the pipe or approximately 7000�eet will be constructed aboveground. The downstream end of the proposed storm system will include an energy dissipator and approximate)y 100Ifeet of buried storm pipe adjacent to the stream. To minimize the introduction of sediment into the stream d ring construction of the outfall str ture, a temporary 18-inch pipe will be installed to divert flows around the construction area. The pipe will beJbIarong the streambed on the opposite nstruction, beginning at a point approximately 20 feet upstream of the proposed structure. A sandbag headwall will be constructed by hand around the end of the pipe to act as a dam and direct the stream flow into the pipe. Plastic sheeting will be used on the upstream side of the headwall to minimize infiltration through the sandbags. The bypass pipe will discharge approximately 20 feet downstream of the energy dissipator. Two sandbag check dams will be placed 50 feef'part in the stream downstream of the bypass pipe to provide an additional barrie�ediment. The bypass pipe, headwall and check dams will be removed at,the completion 44fie project. DE9CRIBEfHE PURPOSE OF THE PROPOSED WORK AND WHY YOU WANT OR NEED TO PERFORM IT AT THE SITE, PLEASE EXPLAIN ANY SPECIFIC NEEDS THAT HAVE INfLUENC �_/_ _ � THE DESIGN. 4 15 1"y'1`C. The purpose of this project is to replace an existing 700-foot-long metal storm pipe with a new High Density Polyethylene (HDPE) pipe of the same diameter. The project is needed to replace the existing storm system which is aging and in need of extensive repair. As the result of fallen trees,,The pipe has been crushed in several locations, reducing its conveyance capacity. The upper 60 feet of the buried portion of pipe is so severely damaged that the pipe joints have separated allowing water to infiltrate into the underlying soil. This condition may potentially weaken the slope causing failure. Due to the proximity of the of the two petroleum pipelines which cross under the storm drain, there is concern that a slope failure in the vicinity of the leaking storm pipe could potentially result in damage to the petroleum lines. Additionally, one of the two manhole structures on the slope has been undermined as a result of undercutting from the adjacent stream and is in danger of collapsing. The proposed storm pipe replacement project will reduce erosion at the pipe outlet and eliminate the chance of landslides occurring at the top of the slope as a result of the leaking pipe. The elimination of intermediate manholes will also reduce the chance of landslides and erosion occurring at other locations as a result of pipe leaks or failure of structures. The majority of the storm s tem will be relocated further away from the stream(classified as Type 4)than the existing storm system,thus eliminating any stream crossing ` sed project. � 4— , 7c.

I hope to have a draft ready for you to review late next week. Questions: 1. How wide will the utility corridor be and how wide do you think the construction corridor(i.e., cleared area)will be? 2. Can you provide me with some information on the construction involved with the stormwater pipe installation? I need a general idea of the type of equipment that will be used, trenching if any, and any support structures for the aboveground section of the pipe. I have information on fill and have a pretty clear picture of the outfall construction, but can't seem to piece together the construction process for the rest of the project. I came across a reference to removal of the existing pipe being done by hand. Will any other part of the construction process be done by hand? I'm assuming the staging area will be along the maintenance roads. 3. What hours of the day will construction take place? I've put in the BA that construction will start summer of 2001. Do you have specific months in mind (realizing it's dependent on the permit process)? 4 The diagrams in the geotechnical report apparently were 11x17"and folded. They weren't unfolded when they were copied. Could you fax me copies? You'll probably need to photocopy them in two parts and then fax them. Our fax number is 206-789-9684. That's it for now. There will probably be little things you'll need to add to the project description when you review the draft, but your answers to these questions should help me fill in most of the gaps.

(Adolfson)has prepared this Biological Evaluation(BE)to facilitate review of the proposed project as required by section 7(c)of the Endangered Species Act (ESA). This BE has been prepared particularly to facilitate coordination between the United States Army Corps of Engineers,the action agency,and the National Marine Fisheries Service(NMFS) and the United States Fish and Wildlife Service (USFWS) jointly referred to as the Services. The NMFS regulates federally-listed threatened and endangered marine wildlife and anadromous fish stocks. Threatened and endangered terrestrial wildlife,plants, and inland fish stocks are under the jurisdiction of the USFWS. The purpose of this study is to determine the need for consultation or conference with the Services by providing site-specific information regarding the proposed action; data on listed,proposed, and candidate species; and a discussion of the effects of the proposed action on those species. Information provided by NMFS (NMFS, 2000a) and USFWS (USFWS, 2000) indicates that the project will occur within the general range of the following species of concern: Common Name Scientific Name ESA Status Jurisdiction Coastal/Puget Sound Bull Salvelinus Threatened USFWS Trout confluentus Puget Sound ESU Chinook Oncorhynchus Threatened NMFS Salmon tshawytscha Puget Sound/Strait of Oncorhynchus Candidate NMFS Georgia ESU Coho Salmon kisutch 10STUDY OBJECTIVES This study has the following objectives: • To review information on species within the action area. The document includes a literature review and discussions on the expected level of use of species from public resource information. A Washington Department of Fish and Wildlife (WDFW) Priority Habitats and Species Map was obtained for records of state priority species occurrence in the project area (WDFW, 2000). The Washington Department of Natural Resources (WDNR)Natural Heritage Program was also contacted for information on priority plants in the area(WDNR, 2000). A list of pertinent references is provided at the end of this report. Agency correspondence with USFWS is provided in Appendix B. • To conduct a site survey of the project area in order to observe species habitat. Adolfson planner Ann Root and biologist Kris Jaeger conducted a field review of the project on August 15, 2000. • To assess the Properly Functioning Conditions (PFC) of streams within the action area as described by NMFS (1998) and USFWS (1998). Estimates in the PFC assessment are based on observations made during the field visit,background materials, and information provided by WDFW biologists. A PFC summary is included in Appendix A of this BA Table 1). • To discuss direct, indirect, and interrelated and interdependent effects to the species and habitats resulting from the proposed action, as well as to review known cumulative effects. • To provide a recommendation with regard to effect determinations. If the action agency determines that a project "is likely to adversely affect" listed species or critical habitat, then .formal consultation is required unless an exception applies. If the action agency determines that a project will have "no effect" or is "not likely to adversely affect" listed species or habitat, and the Services provide written concurrence, formal consultation is not required. 4.ODESCRIPTION OF PROPOSED ACTION AND ACTION AREA 4.1 Primary Project Features 4.1.1 Stormwater Pipe Replacement and Realignment The proposed project includes the replacement of an existing 700-foot long 18-inch corrugated metal stormwater pipe with approximately 800 feet of High-Density Polyethylene (HDPE) 18-inch stormwater pipe. The stormwater pipe runs from the detention pond at the Sunnydale Mobile Home Park at Union Avenue down a ravine and along an unnamed stream (Figure 2). The stormwater pipe discharges into that stream near the intersection of SE 5th Street and Newport Avenue SE, north of the Maple Valley Highway. The new stormwater pipe will be installed along a different alignment at the same location. The current alignment of the pipe is buried for a length of 160-feet along a flat section at the top of a slope. This section crosses two Olympic Pipeline Company (OPLC)petroleum lines. The rest of the stormwater pipe is aboveground following the fall line down a steep slope (23 to 67 percent), crossing the stream on timber and steel cribbing, following a narrow shelf next to the stream, and discharging into the stream. The upper 60 feet of the aboveground pipe section has been partially crushed and the joints have separated. Water leakage from this pipe section onto the steep slope has the potential to affect slope stability (Zipper Zeman, 2000). The upper section of the stormwater pipe that is currently buried will be replaced in the existing trench with a minimum one-foot clearance above the OPLC crossing. The remaining section of the pipe will be constructed along a new alignment on the south side of the stream avoiding the steeper portion of the slope, crossing the stream, and the lower streambank. Replacement of the buried section of the pipe will require use of a backhoe and dump truck for shoring and excavation of the existing trench. Approximately 16 cubic yards of controlled density fill will be installed in the trench to protect the existing OPLC pipelines. Two rock buttress are located on the slope adjacent to the upper detention pond. These buttresses were installed to stabilize a small landslide on the slope between the pond and the access road. The Geotechnical Engineering Study conducted for the project found no evidence of recent movement in the area and found that the rock buttress appeared to be effective at controlling erosion(Zipper Zeman, 2000). One rock buttress will be dismantled as part of the project and reassembled on site. Additional rock backfilling of the buttress may be required. The above ground portion of the pipe will be laid from the top of the slope. The pipe segments will be lowered down the slope with cable and fused together. Staging areas will be located on the existing maintenance roads at the top of the hill and at along the lower portion of the stream. The construction and maintenance easement of the pipeline will be 15 feet wide. 4.1.2 Installation of Energy Dissipator The existing stormwater pipe discharges directly into the stream with a drop of approximately 4 feet. The streambank and streambed have been eroded and scoured out at the outfall (See Photo X). The outfall will be relocated appi'kimately XX-feet d and replaced with an energy dissipator to reduce erosion and scour. The energ y lissipator will consist of a riprap outfall. Approximately 20 cubic yards of soil w� will be removed during outfall construction. To divert flows around the construction site, a temporary headwall and 18-inch bypass pipe will be installed upstream of the site. The headwall will be constructed of gravel sandbags and lined with plastic. The bypass pipe will discharge approximately 15 feet downstream of the construction site. Two sandbag check dams will be placed in the stream downstream of the bypass pipe, approximately 50 feet apart. The bypass pipe, headwall and check dams will be removed when the project is completed. 4.1.3 Clearing The project will require only minor clearing of shrubs,blackberries and grasses. No trees will be removed. Shrubs and blackberies will be cleared at the top of the project where the pipe will be buried and along a portion of the aboveground alignment. Some grasses will be disturbed during installation of the energy dissipator. All disturbed soils along the easement corridor will be planted with native shrubs and trees and hydroseeded upon completion of the pipeline installation. The project will not require additional clearing for construction staging areas. 4.1.4 Removal of Existing Corrugated Metal Stormwater Pipe The existing Corrugated Metal Pipe (CMP)will be removed as part of the project. Removal will include the cribbing, manholes and other structures. Because of the steep slopes, the existing CMP and other structures will be removed by hand. Sul'rVV✓rIi vt'gt tl0h 4.2 Secondary Project Features 4.2.1 Timing, Noise, and Detours The project is scheduled to occur during the summer of 2001 and is estimated to last 3 to 4 weeks. Work will occur between the hours of 7:00 a.m. and 4:00 p.m., Monday through Friday. The project will require construction machinery typical of minor trenching projects (backhoes, dumptrucks, etc.). Noise disturbances from the construction activity are anticipated to be typical of other small-scope construction projects and could be as high as 90 dBA. These noise levels are expected for the duration of the construction. The project will not require highly disruptive activities such as blasting or pile driving. No long-term noise will be generated by the project. The proposed project will be accessed from existing maintenance roads and will not require a detour of road traffic on adjacent city streets. 4.2.2 Stormwater Pipe Operation and Maintenance The proposed stormwater pipe will operate as a gravity flow pipe. The stormwater pipe will be incorporated into the regular maintenance schedule determined and conducted by the City of Renton. 4.3 ACTION AREA AND HABITAT DESCRIPTION The action area includes all areas where work will take place and any adjacent areas that may be affected by the proposed project. To account for federally-listed and candidate fish species, the action area will include the aquatic environments of an unnamed tributary to the Cedar River, the potential mixing area of the Cedar River(100 yards upstream and 2,000 yards downstream of its junction with the unnamed tributary), and all terrestrial environments within one mile of the project area. The project area includes an approximately 15-foot wide corridor along the proposed alignment of the stormwater pipe (Figure 3). The alignment for the stormwater pipe begins at a detention pond near the southeast corner of the Sunnydale Mobile Home Park located west of Union Avenue in the City of Renton. The stormwater pipe will extend approximately 800 feet southwest down a ravine and along an unnamed tributary of the Cedar River. The pipe will discharge stormwater into the stream near the intersection of SE 51h Street and Newport Avenue SE, north of the Maple Valley Highway (flM. 4.3.1 Environmental Baseline 4.3.1.1 Terrestrial Environment The proposed projected is located in an undeveloped ravine and riparian corridor. Slopes in the ravine range from 23 to 67 percent. Vegetation consists of mixed deciduous and evergreen trees, shrubs, ferns and grasses (See Photos X and X). The shrub layer on the lower slope is dominated by blackberries (See Photo X). Land use surrounding the project area is characterized by the ravine and riparian corridor and by single family homes, maintained lawns, and landscaped, ornamental plantings. 4.3.1.2 Aquatic Environment Unnamed Stream The stormwater pipe is laid in the riparian corridor and discharges into an unnamed stream that is tributary to the Cedar River. The stream is unclassified on the King County Sensitive Areas Map and not shown on USGS topographic maps of the area. It is identified as stream 5-29 in the City of Renton's Critical Areas Ordinance. The stream is a small perennial drainage fed by groundwater. It starts from a groundwater seep on the slope of the ravine and discharges into the Cedar River approximately 0.5 mile downstream of the project site (Figure 2). Summer flows in the stream are less than 1 cfs (See Photo X), but the stream floods occasionally in winter. Below the project site,the creek flows in a ditch next to the maintenance road and approximately 1,300 feet below the project site,the stream flows into two detention ponds connected by a culvert(See Photo X). The stream flows out of the last detention pond through a standpipe and into a 24-inch stormpipe that flows approximately 350 feet under the Maple Valley Highway and discharges into the Cedar River(Photo X). Within, and immediately downstream of the project area,the riparian corridor of the stream is dominated by mixed second-growth forest, shrubs, ferns and Himalayan blackberry (Photos X and X). Below the project area where the stream is ditched,the riparian corridor is bordered by maintained lawns on the south and overgrown grasses on the north(Photo X). The stream is entirely culverted below the detention ponds. The stream does not meet the criteria of properly functioning conditions for any of the parameters detailed in Table 1 (Appendix A). Instream habitat features are limited throughout the stream due to its small size and presence of extensive culverted portions. Anadromous fish species are precluded from the stream. Cedar River The Cedar River flows from its headwaters in the Cascade Mountains to Lake Washington. The upper reach of the river has been dammed at Chester Morse Lake to provide drinking water supply for the City of Seattle. The upper Cedar River watershed is protected as a public watershed and is closed to public access. In its lower reaches,the river is channelized and surrounded by extensive urban and industrial development in the a City of Renton. At its junction with the unnamed stream,the River is still relatively undeveloped and meanders through a broad valley with steep slopes. Arc we Ca� �Q �( /5 . . Ccn C7-uynn - Sunnydale BA and permit info Page 1 From: Root, Ann <aroot@adolfson.com> To: <aquynn@ci.renton.wa.us> Date: 9/12/00 9:13AM Subject: Sunnydale BA and permit info Allen, I intended to call you last week, but I got tied up in another project with a deadline. I checked with our Corps permitting experts and have some information for you about the permit process. You indicated when we spoke last that you were waiting for the BA to submit the JARPA. Our staff says there is no advantage to doing that. You should go ahead and file the JARPA to get the rest of the permit process going. There is also no particular advantage to waiting to submit the 404 permit with the BA. It is better to get the permits into the queue as early as possible. You asked about the Nationwide permit process and who decides if one applies to this project. The Corps will decide if there is an applicable Nationwide permit when you submit the 404. So, you should just complete the 404 application and submit it to the Corps. I still haven't received the species list from the USFWS. I'm about ready to call and ask what happened to it since the request was sent it a long time ago. I can go ahead and start working on the BA without the list and make alterations as necessary when the list comes in. We have been having some internal discussions about whether to submit the BA as a "no effect" or as a "may affect, not likely to adversely affect." We are leaning toward the latter since the project is so close to the Cedar River. It seems like the conservative call to make. A couple of questions about the project. 1. Is the SEPA appeal process complete and if so, what was the result? 2. Do you have any information about winter flows on the creek? Obviously, it couldn't support much in the way of fish life in the summer, but if winter flows are more constant, fish might have historically used the creek and resident fish may use it currently. What about flood flows? There are indications in some of the documents you gave me that the creek floods regularly. Can you provide any information on that? If a geotechnical report was done for the project, that would help me out. 3. Do the winter flows ever exceed the capacity of the detention ponds? If you could provide me with that information, it would help with the BA. My plan is to have the BA to you by the end of the month and hopefully a little sooner if the species list comes in and my other large project calms down a little. I'll try to follow this up with a phone call later today or feel free to call me. Thanks.

Box 3755 Seattle, WA 98124-2255 SUBJECT: CITY OF RENTON STORMWATER PROJECTS CORRECTING PROJECT INFORMATION Last week I spoke to Lori Morris about a form letter we received regarding the Lake Washington Storm System Project(attached). When I asked her why we received the letter,she read a project description that did not match my project. It appears that the City placed the project information for two City projects in the wrong envelopes when they were sent to you. I have enclosed the correct project information for both projects. In our opinion,a permit from the Corps is not required for the Lake Washington Storm System Project. Please review the information, correct your files,and let us know the permit status for both projects. Project Number LUA-00-055,ECF,SM Lake Washington Storm System Project Project Manager: Daniel Carey (425) 430-7293 The project will construct about 1,200 feet of stormwater pipes in Lake Washington Blvd,N 34th ST, and Burnett Ave N, replacing the existing system of pipes,roadside culverts and ditches. The project is about 130 feet from Lake Washington,but does not include any work in the lake or lake shore. Project Number LUA-00-071,ECF,V-H Sunnydale Storm System Replacement Project Project Manager: Allen Quynn (425)430-7247 The project will replace an existing 700-foot-long corrugated metal pipe down a steep hillside with a new high-density polyethylene pipe. The new pipe system includes a new energy dissipater and outfall to replace the existing pipe and outfall. We would appreciate a quick review of the information since we would like to start construction on both projects in the late summer of this year. If you have any questions regarding the projects, please call either Allen or me.

USEFUL DEFINITIONS The following definitions are presented to help applicants In completing the JARPA. They may not necessarily represent specific language from the laws implemented through JARPA. Ordinary High Water Mark or Line means the visible line on the banks where the presence and action of waters are so common as to leave a mark upon the soil or vegetation:Provided,that In any area whom the ordinary high water line cannot be found the ordinary high water line adjoining saltwater shall be the line of mean higher high water and the ordinary high water line adjoining freshwater shall be the elevation of the mean annual flood. I Mean Lower Low Is the 0.0 tidal elevation,determined by averaging each day's lowest tide at a particular location over a period of 19 years. it Is the tidal datum for vertical tidal references In the salt water area. Mean High Water and Mean Higher High Water Tidal Elevations at any specific location can be found in tidal benchmark data compiled by the United States Department of Commerce, Environmental Science Services Administration, Coast and Geodetic Survey, dated January 24, 1979. This information can be obtained from the Corps of Engineers at(206)764-3495. The determination of tidal elevation is obtained by averaging each day's highest tide at a particular location over a period of 19 years, measured from mean lower low water, which equals 0.0 tidal elevation. Shorelands or shoreland areas means those lands extending landward for two hundred feet in all directions as measured on a horizontal plane from the ordinary high water mark; floodways and contiguous floodplain areas landward two hundred feet from such floodways; and all wetlands and river deltas associated with the streams, lakes, and tidal waters which are subject to the provisions of 90.58 RCW. Shorelines means all water areas of the state, including reservoirs, and their associated wetlands, together with the lands underlying them, except stream segments upstream of the point where mean annual flow is less than 20 cubic feet per second, and lakes less than 20 acres in size. Wetlands means areas that are inundated or saturated by surface water or ground water at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands generally include swamps, marshes, bogs, and similar areas. Bridge means any structure including pipelines and conveyor belts, which transports traffic or materials across a navigable water.

Appendix C APPENDIX C WATER TYPE MODELING Introduction Stream or water classification is a systematic arrangement of streams and other water bodies in groups or classes according to specified criteria. These criteria include physical characteristics, processes,and beneficial uses. In Washington,different stream typing systems are used to manage for the beneficial uses(e.g.,fish habitat and water quality)of streams. The Department of Natural Resources(DNR)and other state agencies currently use presence of fish and protection of downstream water quality to classify streams for management purposes. On state and private timberlands,the classification of streams dictates the management activity level permitted adjacent to the stream type. The system for classification of waters in Washington is a key factor in the framework for landscape management. Currently,forest practices in riparian management zones are regulated according to the stream typing system.Thus,the stream typing system used across the landscape directly affects land management. The land management along streams or riparian areas can beneficially or adversely affect the beneficial uses of the streams and the functions of the riparian areas for aquatic and terrestrial species. In order to quantify the current extent of water types and riparian protection associated with those types,the existing DNR mapping and classification of streams can be used. This mapping can be used to represent Alternative 1 in this EIS. In order to quantitatively compare Alternative 1 with the other alternatives,modeling must be used to represent Alternatives 2 and 3. This appendix describes the stream typing under the alternatives and the modeling used to represent Alternatives 2 and 3. Description of Water Typing Under the Alternatives Under Alternative 1,water typing rules would be the same as the current permanent rules. The waters identified in the state's GIS hydrography coverage have been classified according to these water types. Five water types are recognized as follows: • Type 1: Major waterways of the state including rivers,lakes,and saltwater. They include all waters inventoried as"shorelines of the state." • Type 2: Waters,not classified as Type 1,which have high fish,wildlife,or human use. They generally are streams wider than 20 ft. in bankfull width. • Type 3: Waters,not classified as Types 1 or 2,which have moderate to slight fish,wildlife,or human use. They generally are less than 20 ft.in bankfull width. Draft EIS Water Type Modeling GAWP\21971APPENDiX CAA•3/14/2000 C-1 Appendix C • Type 4: Waters not classified as Types 1,2,or 3,which are important for protecting downstream water quality. They generally are streams wider than 2 ft. in bankfull width. • Type 5: Waters not classified as Types 1,2,3,or 4. They are generally seasonal headwater streams,less than 2 ft. in bankfull width. Under Alternative 2,three water types,plus two subtypes are recognized as follows: • Type S: All waters inventoried as"shorelines of the state." • Type F: Waters not classified as Type S,which contain fish habitat. It also includes some waters diverted for domestic and fish hatchery use. • Type N: Waters not classified as Type S or F,which are either perennial streams or are physically connected by an above-ground channel system to downstream waters such that water or sediment initially delivered to such waters will eventually be delivered to a Type S or F water. Type N waters include two subtypes:perennial and seasonal streams. Under Alternative 3,a geomorphic-based system consisting of three water types is recognized as follows: • Waters with a gradient between 0 and 20 percent;these are channels considered to be important for fish. • Waters with a gradient between 20 and 30 percent;these are channels considered to be important for coarse sediment storage and as a source of LWD. • Waters with a gradient greater than 30 percent;these are channels considered to be important because they are prone to channelized landslides and as a source of LWD. Modeling of the Alternative Water Typing Systems As discussed above,the DNRs GIS hydrography coverage can be used to represent Alternative 1 directly. However,to compare Alternative 1 with the other two alternatives,assumptions must be made and Alternatives 2 and 3 modeled using available information. The following approach was followed to represent these two alternatives. It relies on existing hydrography data consisting of stream location and stream type,stream gradient classification(generally based on 10-m DEMs and 30-m DEMs where 10-m DEMs were not available),and basin size. Initial Approach For both Alternatives 2 and 3,the following initial steps were taken using the sample sections described in Appendix A: • The DNR hydrography layer was acquired for the sample sections within Washington state. The DNR hydrography layer classifies waters by Types 1 through 5,and Type 9. • A GIS AML was used to determine the gradients of the streams in the sample sections. Stream gradient classes were mapped along each stream segment;these were broken down into 0-20 Water Type Modeling Draft EIS GAWPA219'A"PENDIX C.&c•3/I4/2000 C-2 Appendix C ` percent,20-30 percent,and greater than 30 percent classes. Gradient classification used the available DEMs,which were generally 10-m DEMs;30-m DEMs were used where these were not available. In addition, slope classes were mapped over the entire section based on the DEMs. These were broken down into slope classes of 0-16 percent, 16-20 percent,and greater than 20 percent. • In order to improve the quality of the gradient classification,an individual map of each section containing the above information,was printed and reviewed by a hydrologist. Where discrepancies were observed between the gradient class of the stream as mapped and the gradient of the topographic location of where the stream should have been mapped,changes were made to stream gradient classes so that they more accurately reflected the available topographic information. Alternative 2 Approach For Alternative 2,the following rules were applied: • All current Type 1 streams were converted to Type S streams by definition. All current Type 2 and 3 streams were converted to Type F streams. — Type 4 streams with the following characteristics were converted to Type F streams: — Type 4 streams with gradients between 0 and 16 percent; — Type 4 streams with gradients between 16 and 20 percent and a basin size greater than 50 acres in western Washington or 175 acres in eastern Washington • All other Type 4 streams and all Type 5 streams(including Type 9's on the west side) streams were considered nonfish-bearing,Type N streams. • The following definitions(from the Forests and Fish Report)were used for separating perennial from seasonal nonfish-bearing streams: — Type 4 streams are considered perennial if their basin sizes are greater than 13 acres in the Coastal zone of western Washington(based on the Sitka Spruce zone of Franklin& Dymess, 1973), 52 acres in all other areas of western Washington,or 300 acres for all areas in eastern Washington. All other Type 4s,as well as all Type 5s and Type 9s(on the westside)are considered seasonal. It was recognized that this approach for defining fish-bearing streams probably overestimates the number of fish-bearing waters and underestimates the Type N perennial streams(Pers.Comm., Mark Hunter,Washington Department of Fish and Wildlife, 1999). Alternative 3 Approach For Alternative 3,the following rules were applied: • All streams were classified based on their gradient class only. Stream type was not taken into account,except that Type 9 streams in eastern Washington were not included(since most of these turn out to be dry draws. Draft EIS Water Type Modeling GAWM2197WPPENDIX C.do •3/14/2000 C-3 Appendix C Results Table 1 displays the number of stream miles in the sample sections(see Appendix A)by region and major land ownership for all vegetation types. Table 2 displays the number of stream miles under the current stream typing system(Alternative 1)in the sample sections for state and private forest lands by region. Table 3 displays the number of stream miles in the sample sections under the proposed stream typing broken down in the same way for Alternative 2,and Table 4 displays the same information for the Alternative 3 stream typing system. A graphical comparison of the stream typing systems in the sample sections is displayed in Figure 1. Since riparian protection rules are a relatively recent phenomenon in Washington state,the majority of riparian forests on private and state lands has been logged at least once. Most streamside vegetation is relatively young or in an early seral stage. In order to estimate the proportion of stream miles in different seral stages,we classified the available vegetation data according to the classification given in Table 5. This produced the seral stage breakdown shown in Table 6 for private lands. Table 1.
