Based on the information you provided to us,NWP 27, Stream and Wetland Restoration Activities, authorizes your proposal to place fill in waters of the United States to facilitate in- stream restoration, as depicted on the enclosed drawings dated May 2004. The project would occur in Maplewood Creek at Renton, in King County, Washington. In order for this NWP authorization to be valid, you must ensure that the work is performed in accordance with the enclosed Nationwide Permit 27, Terms and Conditions and the following special conditions that we have added to ensure that this project would have no more than a minimal adverse impact on the aquatic environment: a. You must implement the ESA requirements and/or agreements set forth in the reference biological evaluation titled, "Reference Biological Evaluation Specific Project Information Form for Nearshore Fill,"dated May 27, 2004, in their entirety. The U.S. Fish and Wildlife Service concurred with a finding of`may affect, not likely to adversely affect"base on this document on August 25, 2004 (USFWS Reference# 1-3-04-I-1524). The National Marine Fisheries Service concurred with a finding of"may affect, not likely to adversely affect"based on this document on August 2, 2004 (No NMFS reference number assigned). 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 Puget Sound Chinook and coastal-Puget Sound bull trout the permittee may conduct the authorized activities from July 16th through October 15th in any year this permit is valid. The permittee shall not conduct work authorized by this permit from October 16th through July 15th in any year this permit is valid. -2- You are cautioned that any change in project location or plans will require that you submit a copy of the revised plans to this office and obtain our approval before you begin work. Deviating from the approved plans could result in the assessment of criminal or civil penalties. Please note that we may need to reinitiate Endangered Species Act Section 7 consultation with the National Marine Fisheries Service and/or U.S. Fish and Wildlife Service in order to authorize any work not already included in the enclosed plans. In order for this NWP authorization to be valid, the State of Washington(State)must have issued or waived Section 401 Water Quality Certification(WQC) and, for Washington's 15 coastal counties, concurred with or waived a Coastal Zone Management(CZM) consistency determination. Based on our review of the proposed work, the Corps has determined that the proposed work will be in compliance with the State's WQC and CZM consistency determination concurrence requirements for this NWP. Therefore, no further coordination with the State is required. We have reviewed your project pursuant to the requirements of the Endangered Species Act (ESA). After consulting with the National Marine Fisheries Service and the U.S. Fish and Wildlife Service,we have determined that this project meets the requirements of NWP National General Condition 11 provided you comply with special conditions"a" and "b" listed above. We have also reviewed your project pursuant to the requirements of the Magnuson-Stevens Fishery Conservation and Management Act, as amended by the Sustainable Fisheries Act of 1996 in regards to Essential Fish Habitat (EFH). We have determined that the proposed action will not adversely affect EFH for federally managed fisheries in Washington. Our verification of this NWP authorization is valid for 2 years from the date of this letter unless the NWP is modified or revoked prior to that date. If the authorized work has not been completed by that date,please contact us to discuss the status of your authorization. This verification includes a preliminary jurisdictional determination that is not appealable. More information about our administrative appeal process is available on our website at: hq://www.nws.usace.army.mil/PublicMenu/Menu cfm?sitename=REG&pagenanie=Appeals If this project complies with all terms and conditions of this authorization, you will need no further authorization from us. However, you must still obtain all State and local permits that apply to your project. Also, we remind you that failure to comply with all terms and conditions of this NWP verification invalidates your authorization and could result in a violation of Section 404 of the Clean Water Act. Upon completing the authorized work, please fill out and return the enclosed Certificate of Compliance with Department of the Army Permit form to the address indicated on the form. Your signature on this form is our assurance that the completed work and any required mitigation was conducted in accordance with the terms and conditions of this NWP. -3- Thank you for your cooperation during the permit process.

Further Information—page 14 In addition to any special condition that may be required on a case-by-case basis by the District Engineer, the following terms and conditions must be met, as applicable, for a Nationwide Permit 27 authorization to be valid in Washington State. A. DESCRIPTION OF AUTHORIZED ACTIVITIES Activities in waters of the US associated with the restoration of former waters, the enhancement of degraded tidal and non-tidal wetlands and riparian areas,the creation of tidal and non-tidal wetlands and riparian areas, and the restoration and enhancement of non-tidal streams and non-tidal open water areas as follows: (a) The activity is conducted on: (1) Non-Federal public lands and private lands, in accordance with the terms and conditions of a binding wetland enhancement,restoration, or creation agreement between the landowner and the U.S.Fish and Wildlife Service(FWS)or the Natural Resources Conservation Service(NRCS),the National Marine Fisheries Service, the National Ocean Service,or voluntary wetland restoration, enhancement, and creation actions documented by the NRCS pursuant to NRCS regulations;or (2) Reclaimed surface coal mine lands,in accordance with a Surface Mining Control and Reclamation Act permit issued by the OSM or the applicable state agency(the future reversion does not apply to streams or wetlands created,restored,or enhanced as mitigation for the mining impacts,nor naturally due to hydrologic or topographic features,nor for a mitigation bank);or (3) Any other public,private or tribal lands; (b) Notification:For activities on any public or private land that are not described by paragraphs(a)(1)or (a)(2)above,the permittee must notify the District Engineer in accordance with General Condition 13; and (c) Planting of only native species should occur on the site. Activities authorized by this NWP include,to the extent that a Corps permit is required,but are not limited to:the removal of accumulated sediments;the installation,removal,and maintenance of small water control structures,dikes,and berms;the installation of current deflectors;the enhancement,restoration,or creation of riffle and pool stream structure;the placement of in-stream habitat structures;modifications of the stream bed and/or banks to restore or create stream meanders;the backfilling of artificial channels and drainage ditches;the removal of existing drainage structures;the construction of small nesting islands;the construction of open water areas;the construction of oyster habitat over unvegetated bottom in tidal waters; activities needed to reestablish vegetation,including plowing or discing for seed bed preparation and the planting of appropriate wetland species;mechanized land clearing to remove non-native invasive,exotic or nuisance vegetation;and other related activities. This NWP does not authorize the conversion of a stream to another aquatic use,such as the creation of an impoundment for waterfowl habitat.This NWP does not authorize stream channelization.This NWP does not authorize the conversion of natural wetlands to another aquatic use,such as creation of waterfowl impoundments where a forested wetland previously existed.However,this NWP authorizes the relocation of non-tidal waters,including non-tidal wetlands,on the project site provided there are net gains in aquatic resource functions and values.For example,this NWP may authorize the creation of an open water impoundment in a non-tidal emergent wetland,provided the non-tidal emergent wetland is replaced by creating that wetland type on the project site.This NWP does not authorize the relocation of tidal waters or the conversion of tidal waters,including tidal wetlands,to other aquatic uses,such as the conversion of tidal wetlands into open water impoundments. Reversion.For enhancement,restoration,and creation projects conducted under paragraphs(a)(3),this NWP does not authorize any future discharge of dredged or fill material associated with the reversion of the area to its prior condition.In such cases a separate permit would be required for any reversion.For restoration, enhancement,and creation projects conducted under paragraphs(a)(1)and(a)(2),this NWP also authorizes any future discharge of dredged or fill material associated with the reversion of the area to its documented prior condition and use(i.e.,prior to the restoration,enhancement,or creation activities). The reversion must occur within five years after expiration of a limited term wetland restoration or creation agreement or permit,even if the discharge occurs after this NWP expires.This NWP also authorizes the reversion of wetlands that were restored,enhanced,or created on prior-converted cropland that has not been abandoned, in accordance with a binding agreement between the landowner and NRCS or FWS(even though the restoration,enhancement,or creation activity did not require a Section 404 permit).The five-year reversion limit does not apply to agreements without time limits reached under paragraph(a)(1).The prior condition will be documented in the original agreement or permit,and the determination of return to prior conditions will be made by the Federal agency or appropriate state agency executing the agreement or permit.Before any reversion activity the permittee or the appropriate Federal or state agency must notify the District Engineer and include the documentation of the prior condition.Once an area has reverted to its prior physical condition,it will be subject to whatever the Corps Regulatory requirements will be at that future date.(Sections 10 and 404) 2 Note: Compensatory mitigation is not required for activities authorized by this NWP,provided the authorized work results in a net increase in aquatic resource functions and values in the project area.This NWP can be used to authorize compensatory mitigation projects,including mitigation banks,provided the permittee notifies the District Engineer in accordance with General Condition 13,and the project includes compensatory mitigation for impacts to waters of the US caused by the authorized work.However,this NWP does not authorize the reversion of an area used for a compensatory mitigation project to its prior condition.NWP 27 can be used to authorize impacts at a mitigation bank,but only in circumstances where it has been approved under the Interagency Federal Mitigation Bank Guidelines. B. CORPS REGIONAL CONDITIONS FOR THIS NWP 1. If the proposed work results in impacts to a special aquatic sites(e.g.,wetlands or riffle and pool complexes),the"Notification"must include a statement of why the impacts are necessary,how the impacts have been minimized,and how the overall project is beneficial,despite these impacts. 2. The permittee must notify the District Engineer in accordance with General Condition 13 for proposed projects in stream or wetland restoration and enhancement areas previously authorized as mitigation by a Department of the Army permit. 3. The permittee must notify the District Engineer in accordance with General Condition 13 for a stream and wetland restoration projects occurring in a designated Federal Superfund site(Comprehensive Environmental Response,Compensation and Liability Act),hazardous waste clean-up site(Resource Conservation and Recovery Act),or State clean-up site(Model Toxics Control Act). NOTE: The restoration of former waters can occur in either tidal or non-tidal waters. However,NWP 27 cannot be used for the enhancement or creation of tidal waters other than wetland and riparian areas. See the definition section for more information. C. EPA, Puyallup Tribe and Chehalis Tribe WQC CONDITIONS FOR THIS NWP EPA,Puyallup Tribe and Chehalis Tribe water quality certification(WQC)has been denied without prejudice. An individual WQC is required for all Section 404 activities. D. STATE WQC CONDITIONS FOR THIS NWP State WQC has been partially denied without prejudice for this permit. Written approval of the proposed mitigation plan for the project is required by Ecology for the activities and impacts listed below: 1. Any fill-related impacts to tidal waters or to non-tidal wetlands adjacent to tidal waters. 2. Any fill-related impacts greater than'/Z acre. An individual 401 certification,in addition to an approved mitigation plan, is required prior to starting work for the following: a. For the activities listed in 1.and 2.above where Ecology determines the mitigation proposed for the project is insufficient and written approval is not received; b. Any project impacting 1 acre or greater of wetlands 3 NOTE: Mitigation plans submitted for Ecology review and approval shall be based on the guidance provided in Guidelines for Developing Freshwater Wetlands Mitigation Plans and Proposals(Ecology Publication 94-29 or as revised). For projects proposing mitigation at an Ecology-approved mitigation bank,applicants shall provide a copy of the bank credit withdrawal transaction recorded at the county auditor's office. An individual 401 Certification is required for projects or activities authorized under this NWP if the project/activity will likely result in any of the following adverse effects: 1. The project or activity will likely cause or contribute to an exceedance of a State water quality standard (WAC 173-201A)or sediment quality standard(WAC 173-204). The requirement to obtain an individual 401 certification shall not apply to projects or activities that are carried out in accordance with the following permits,approvals,or management practices. These projects are presumed to comply with state water quality standards including state sediment management standards: a. Projects or activities where the discharges authorized under this NWP are explicitly authorized or covered by a National Pollutant Discharge Elimination System permit. b. Projects,activities or portions of projects or activities designed,constructed and maintained in accordance with the stormwater standards and practices contained in the most current version of Ecology's Stormwater Manual or an Ecology approved equivalent. 2. For projects/activities not designed in accordance with either Ecology's stormwater manual or an Ecology approved equivalent,or for projects where there is credible site specific information which indicates that the permits,approvals,or management practices identified above will not be sufficient to meet state water quality standards,the applicant may provide documentation with the application that the project/activity will otherwise comply with state water quality standards. An individual 401 Certification is required for projects which are unable to provide documentation that the project/activity will otherwise comply with state water quality standards. 3. Projects or activities that cause or contribute to a discharge to a waterbody on the state's list of impaired waterbodies [i.e.,the 303(d)list] and the discharge may result in further exceedances of a specific parameter the waterbody is listed for. The current list of 303(d)-listed waterbodies is available on Ecology's web site at http://www.ecy.wa.gov/programs/wq/303d/1998/1.998__by wrias.html or by contacting Ecology's Federal Permits staff. NOTE: An individual 401 Certification will not be required if the applicant provides documentation showing that the project or activity will either not result in a discharge containing the listed parameter or,if present,the parameter will not contribute to an increased impairment of the waterbody. 4. Projects that do not incorporate structures and/or modifications beneficial for fish or wildlife habitat(e.g., soil bioengineering,biotechnical design,rock barbs,etc.). NOTE: An individual 401 certification will not be required if the project/activity is designed and constructed in accordance to guidelines developed by the Washington State Department of Fish and Wildlife. E. STATE CZM CONSISTENCY DETERMINATION CONDITIONS FOR THIS NWP The Coastal Zone Management(CZM)Consistency Determination has been partially denied without prejudice subject to the 401 Certification conditions for this NWP.

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. Permittees are encouraged to perform work within waters of the United States during periods of low-flow or no-flow. 4. Aquatic Life Movements. No activity may substantially disrupt the necessary life-cycle movements of those species of aquatic life indigenous to the waterbody,including those species that 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 that 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. 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 water quality management measures,the permittee must provide water quality management measures that will ensure that the authorized work does not result in more than minimal degradation of water quality(or the Corps determines that compliance with state or local standards,where applicable,will ensure no more than minimal adverse effect on water quality). An important component of water quality management 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 water quality management 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). This condition is only applicable to projects that have the potential to affect water quality. While appropriate measures must be taken,in most cases it is not necessary to conduct detailed studies to identify such measures or to require monitoring. 5 10. Coastal Zone Management. In certain states,an individual state coastal zone management consistency concurrence must be obtained or waived(see 33 CFR 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(ESA),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 ESA 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 NWP does not authorize the"take"of a threatened or endangered species as defined under the ESA. In the absence of separate authorization(e.g.,an ESA Section 10 Permit,a Biological Opinion with"incidental take"provisions,etc.)from the USFWS or the NMFS,both lethal and non-lethal "takes"of protected species are in violation of the ESA. Information on the location of threatened and endangered species and their critical habitat can be obtained directly from the offices of the USFWS and NMFS or their world wide web pages at http://www.fws.govlr9endspplendspp.html and http://www.nmfs.noaa.gov/prot res/overview/es.html 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 District Engineer 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 notification is complete within 30.days of the date of receipt and can request 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 notification 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 (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). 6 (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. Sketches should be provided when necessary to show that the activity complies with the terms of the NWP(Sketches usually clarify the project and when provided result in a quicker decision.); (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; (6) For NWP 14(Linear Transportation Projects),the PCN must include a compensatory mitigation proposal to offset permanent losses of waters of the US and a statement describing how temporary losses of waters of the US will be minimized to the maximum extent practicable; (7) For NWP 21 (Surface Coal Mining Activities),the PCN must include an Office of Surface Mining (OSM)or state-approved mitigation plan,if applicable. To be authorized by this NWP,the District Engineer must determine that the activity complies with the terms and conditions of the NWP and that the adverse environmental effects are minimal both individually and cumulatively and must notify the project sponsor of this determination in writing, (8) For NWP 27(Stream and Wetland Restoration Activities),the PCN must include documentation of the prior condition of the site that will be reverted by the permittee; (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 1/4-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 1/4-acre in size,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 Facilities),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: 7 (i) Sufficient baseline information identifying 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; (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 for losses of waters of the US were achieved on the project site; (13) For NWP 39 and NWP 42,the PCN must include a compensatory mitigation proposal to offset losses of waters of the US or justification explaining why compensatory mitigation should not be required. For discharges that cause the loss of greater than 300 linear feet of an intermittent stream bed,to be authorized,the District Engineer must determine that the activity complies with the other terms and conditions of the NWP,determine adverse environmental effects are minimal both individually and cumulatively,and waive the limitation on stream impacts in writing before the permittee may proceed; (14) For NWP 40(Agricultural Activities),the PCN must include a compensatory mitigation proposal to offset losses of waters of the US. This NWP does not authorize the relocation of greater than 300 linear-feet of existing serviceable drainage ditches constructed in non-tidal streams unless,for drainage ditches constructed in intermittent non-tidal streams,the District Engineer waives this criterion in writing,and the District Engineer has determined that the project complies with all terms and conditions of this NWP,and that any adverse impacts of the project on the aquatic environment are minimal,both individually and cumulatively; (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 US. For discharges that cause the loss of greater than 300 linear feet of an intermittent stream bed,to be authorized,the District Engineer must determine that the activity complies with the other terms and conditions of the NWP,determine adverse environmental effects are minimal both individually and cumulatively,and waive the limitation on stream impacts in writing before the permittee may proceed; (16) For NWP 44(Mining Activities),the PCN must include a description of all waters of the US adversely affected by the project,a description of measures taken to minimize adverse effects to waters of the US,a description of measures taken to comply with the criteria of the NWP,and a reclamation plan(for all 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;and (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. (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)- (18)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 submit a 8 proposed mitigation plan with the PCN to expedite the process. 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,after considering mitigation,the District Engineer will notify the permittee and include any conditions the District Engineer deems necessary. The District Engineer must approve any compensatory mitigation proposal before the permittee commences 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. The response will state that the project can proceed under the terms and conditions of the NWP. If the District Engineer determines that the adverse effects of the proposed work are more than minimal,then the District Engineer 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 to ensure no more than minimal adverse effects occur to the aquatic environment,the activity will be authorized within the 45-day PCN period. The authorization will include 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 US 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 environmental effects to a minimal level. For activities requiring notification to the District Engineer that result in the loss of greater than 1/2-acre of waters of the US,the District Engineer will provide immediately(e.g.,via facsimile transmission,overnight mail,or other expeditious manner)a copy to the appropriate Federal or state offices(USFWS,state natural resource or water quality agency,EPA,State Historic Preservation Officer(SHPO),and,if appropriate,the NMFS). 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 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 NMFS 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) Wetland 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(1/4-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 NWP verification from the Corps will submit a signed certification regarding the completed work and any required mitigation. The certification will be forwarded by the Corps with the authorization letter and will include: (a) A statement that the authorized work was done in accordance with the Corps authorization,including any general or specific conditions; 9 (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 US authorized by the NWPs does not exceed the acreage limit of the NWP with the highest specified acreage limit(e.g.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 US for the total project cannot exceed 1/3-acre). 16. Water Supply Intakes. No activity,including structures and work in navigable waters of the US 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 US 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 US 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 CWA). 19. Mitigation. 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) The project must be designed and constructed to avoid and minimize adverse effects to waters of the US to the maximum extent practicable at the project site(i.e.,on site). (b) Mitigation in all its forms(avoiding,minimizing,rectifying,reducing or compensating)will be required to the extent necessary to ensure that the adverse effects to the aquatic environment are minimal. (c) Compensatory mitigation at a minimum one-for-one ratio will be required for all wetland impacts requiring a PCN,unless the District Engineer determines in writing that some other form of mitigation would be more environmentally appropriate and provides a project-specific waiver of this requirement. Consistent with National policy,the District Engineer will establish a preference for restoration of wetlands as compensatory mitigation,with preservation used only in exceptional circumstances. (d) Compensatory mitigation(i.e.,replacement or substitution of aquatic resources for those impacted)will not be used to increase the acreage losses allowed by the acreage limits of some of the NWPs. For example, 1/4-acre of wetlands cannot be created to change a 3/4-acre loss of wetlands to a 1/2-acre loss associated with NWP 39 verification. However, 1/2-acre of created wetlands can be used to reduce the impacts of a 1/2-acre loss of wetlands to the minimum impact level in order to meet the minimal impact requirement associated with NWPs. (e) 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. (f) Compensatory mitigation plans for projects in or near streams or other open waters will normally include a requirement for the establishment,maintenance,and legal protection(e.g.,easements,deed restrictions)of vegetated buffers to open waters. In many cases,vegetated buffers will be the only compensatory mitigation required. Vegetated buffers should consist of native species. The width of the vegetated buffers required will address documented water quality or aquatic habitat loss concerns. Normally,the vegetated buffer will be 25 to 50 feet wide on each side of the stream,but the District Engineers may require slightly wider vegetated buffers to address documented water quality or 10 habitat loss concerns. Where both wetlands and open waters exist on the project site,the Corps will determine the appropriate compensatory mitigation(e.g.,stream buffers or wetlands compensation)based on what is best for the aquatic environment on a watershed basis. In cases where vegetated buffers are determined to be the most appropriate form of compensatory mitigation,the District Engineer may waive or reduce the requirement to provide wetland compensatory mitigation for wetland impacts. (g) Compensatory mitigation proposals submitted with the"notification"maybe either conceptual or detailed. If conceptual plans are approved under the verification,then the Corps will condition the verification to require detailed plans be submitted and approved by the Corps prior to construction of the authorized activity in waters of the US. (h) Permittees may propose the use of mitigation banks,in-lieu fee arrangements or separate activity-specific compensatory mitigation. In all cases that require compensatory mitigation,the mitigation provisions will specify the party responsible for accomplishing and/or complying with the mitigation plan. 20. Spawning Areas. Activities,including structures and work in navigable waters of the US 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 provide for not increasing water flows from the project site,relocating water,or redirecting water flow beyond preconstruction conditions. Stream channelizing will be reduced to the minimal amount necessary,and 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. In most cases,it will not be a requirement to conduct detailed studies and monitoring of water flow. This condition is only applicable to projects that have the potential to affect waterflows. While appropriate measures must be taken,it is not necessary to conduct detailed studies to identify such measures or require monitoring to ensure their effectiveness. Normally,the Corps will defer to state and local authorities regarding management of water now. 22. Adverse Effects From Impoundments. If the activity creates an impoundment of water,adverse effects to the aquatic system due to the acceleration of the passage of water,and/or the restricting its flow shall be minimized to the maximum extent practicable. This includes structures and work in navigable waters of the US,or discharges of dredged or fill material. 23. Waterfowl Breeding Areas. Activities,including structures and work in navigable waters of the US 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 designate additional critical resource waters after notice and opportunity for comment. 11 (a) Except as noted below,discharges of dredged or fill material into waters of the US 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 US 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 USFWS or the NMFS 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 it is determined 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 existing Federal Emergency Management Agency's(FEMA)Flood Insurance Rate Maps or FEMA-approved local floodplain maps. (a) Discharges in Floodplain;Below Headwaters. Discharges of dredged or fill material into waters of the US within the mapped 100-year floodplain,below headwaters(i.e.,5 cfs),resulting in permanent above-grade fills,are not authorized by NWPs 39,40,42,43,and 44. (b) Discharges in Floodway;Above Headwaters. Discharges of dredged or fill material into waters of the US within the FEMA or locally mapped floodway,resulting in permanent above-grade fills,are not authorized by NWPs 39,40,42,and 44. (c) The permittee must comply with any applicable FEMA-approved state or local floodplain management requirements. 27. Construction Period. For activities that have not been verified by the Corps and the project was commenced or under contract to commence by the expiration date of the NWP(or modification or revocation date),the work must be completed within 12-months after such date(including any modification that affects the project). For activities that have been verified and the project was commenced or under contract to commence within the verification period,the work must be completed by the date determined by the Corps. For projects that have been verified by the Corps,an extension of a Corps approved completion date maybe requested. This request must be submitted at least one month before the previously approved completion date. G. CORPS REGIONAL GENERAL CONDITIONS FOR ALL NWPS 1. Mature Forested and Bog and Bog-like Wetlands.

Our regulatory program utilizes a series of NWPs to authorize specific categories of work that have minimal impact on the aquatic environment when conducted in accordance with the permit conditions (Federal Register, January 15, 2002, Vol. 67, No. 10). Based on the information you provided to us, NWP 27, Stream and Wetland Restoration Activities, appears to authorize your proposal to place 25 cubic yards of gravel and a temporary sandbag diversion dam in Maplewood Creek provided you are able to comply with the enclosed NWP General Condition 11 as described below. You are not authorized to conduct any of the proposed work in waters of the U.S. until we determine that your project meets all of the NWP conditions. Pursuant to Section 7 of the Endangered Species Act (ESA), the Corps is required to consult with the National Marine Fisheries Service (NMFS) and U.S. Fish and Wildlife Service (USFWS) 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. We submitted an informal consultation concurrence request to the USFWS and NMFS on June 18, 2004, but have not yet received a response. Therefore, your project does not comply with NWP General Condition 11. Upon completion of the consultation process, we will inform you in writing if your project complies with NWP General Condition 11 and if special conditions to your permit or project revisions are required to protect any threatened or endangered species within the project area. Thank you for your patience and cooperation in assisting us complete our permit review. If you have any questions about this letter or our Regulatory program,please call me at (206) 764- 6910 or contact me by email at jonathan.smithausace.aimy.mil . Sincerely, Jo athan Smith Project Manager Enclosure 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(ESA),or which will destroy or adversely modify the critical habitat of such species. Non- federal pern ittees 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 ESA 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 NWP does not authorize the"take"of a threatened or endangered species as defined under the ESA. In the absence of separate authorization(e.g.,an ESA Section 10 Permit,a Biological Opinion with"incidental take"provisions,etc.)from the USFWS or the NMFS,both lethal and non-lethal "takes"of protected species are in violation of the ESA. Information on the location of threatened and endangered species and their critical habitat can be obtained directly from the offices of the USFWS and NMFS or their world wide web pages at http://www.fws.govlr9endspplendspp.html and http://www.nmfs.noaa.govlprot_res/overviewles.html 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 District Engineer 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. 6-21-by 01 DEPARTMENT OF THE ARMY SEATTLE DISTRICT,CORPS OF ENGINEERS P.O.BOX 3755 SEATTLE,WASHIINGTON 98124-3755 REPLY TO JUN 18 2004 ATTENTION OF Regulatory Branch RECEIVED National Marine Fisheries Service JUN 2 12004 Steve Landino, Chief Habitat Branch CITY OF RENTON 510 Desmond Drive Southeast, Suite 103 UTILITY SYSTEMS Lacey, Washington 98503-1263 U.S. Fish and Wildlife Service Ken S.

Mu er Chief Regulatory Branch Enclosure Information Paper US Army Corps Of Engineers Seattle District Date: May 14, 2002 Endangered Species Act Consultation Process' In accordance with Section 7 of the Endangered Species Act(ESA),the U.S. Army Corps of Engineers, Seattle District, Regulatory Branch(Corps) shall consult with the U.S. Fish and Wildlife Service (USFWS) and/or the National Marine Fisheries Service (NMFS)2 on any proposed application for a Department of the Army permit-including Nationwide Permit-that may affect a federally listed species or it's designated critical habitat. Specifics of this consultation process are set forth in 50 CFR Part 402 "Interagency Cooperation—Endangered Species Act of 1973, as Amended". There are two consultation processes under the ESA, informal consultation and formal consultation. You may check the status of the ESA consultation at NMFS via their website—www.nwr.noaa.gov. When entering your Corps reference number, be sure to enter the number in the following format -2003-4-00976. Informal Consultation-When the Corps has determined that a proposed activity will not result in an adverse affect3 to a listed species or critical habitat(which leads to a determination of"may affect,not likely to adversely affect")ESA provides a shortened coordination process called"informal consultation". The process is as follows— Step 1. The Corp initiates consultation with the Services by written request enclosing sufficient biological information, such as a biological evaluation (BE).4 Step 2. With a goal of responding within "30 days",the Services review the BE for completeness and then issue a letter of concurrence to the Corps,request additional information/recommend project alterations, or issue a letter of nonconcurrence. The Corps will initiate "formal consultation" if the Services do not respond to the informal consultation. The Corps is working with the Services to develop reasonable timeframes for informal consultations. Letter of Concurrence. If the Services provide a"letter of concurrence", the Corps will finalize the permit decision. Request for Additional Information/Recommend Project Alterations. The Services may request additional information from the Corps to clarify the proposed project and it's potential impacts or may recommend project alterations to minimize impacts. These requests may occur via a telephone conversation between the Services and the Corps, written requests, or direct coordination with the applicant. Any additional information or project alterations provided by the applicant are sent to the Corps and then forwarded to the Services. 'The Corps has solicited comments from the USFWS and NMFS on this information paper. Certain processes outlined in this paper are proposed by the Corps, as the lead federal agency,and are not necessarily advocated by USFWS and NMFS. 2 USFWS and NMFS are jointly referred to as"the Services". 3,'Adverse affect"is defined as when a listed species or designated critical habitat is negatively impacted as a direct or indirect result of the proposed action or its interrelated or interdependent actions.The negative impacts are not insignificant or discountable. [ESA Section 7 Consultation Handbook,by NMFS and USFWS,dated March 1998] 4 The required biological information for Section 7 Consultation is outlined in 50 CFR 402.12. Letter of Nonconcurrence. If the Services disagree with the Corps' determination,the Services will work informally with the Corps and the applicant to come to a resolution on the non- concurrence. If informal resolution is not possible,the Services will issue a letter of nonconcurrence. The letter may include recommended project alterations to minimize impacts. If the project is not revised by the applicant or via Corps permit conditions,the Corps will inform the Services that the determination has been changed to a"may affect, likely to adversely affect" and reference the original request letter to initiate the "formal consultation"with the Services. Formal Consultation-When the Corps determines that a proposed activity may result in"adverse affects"to listed species or designated critical habitat(a determination of"may affect,likely to adversely affect"), formal consultation is initiated with the Services. The process is as follows— Step 1. The Corps requests formal consultation with the Services in writing, enclosing a complete initiation packages, including biological information such as a BE and a cumulative effects analysis. Step 2. Within 30 days, the Services respond to the Corps, acknowledging receipt of the consultation request and requesting any missing information needed to complete the"consultation initiation package". Step 3. Within 90 days from when the "consultation initiation package"is considered complete,the Services can provide a draft biological opinion(BO)upon request by the Corps,with either a"jeopardy" or"no jeopardy"decision. A"jeopardy"decision may include"reasonable and prudent alternatives" (RPAs)to revise the project so that impacts will result in"no jeopardy"of the listed species. A"no jeopardy"decision may include an incidental take statement along with reasonable and prudent measures (RPMs)and terms and conditions necessary to reach an acceptable level of reduced impact on the species. Step 4. Within 30 days of receipt of the draft BO,the Corps and the applicant review the draft BO and provide comments to the Services. During this review,the Corps and the applicant have the opportunity to discuss terms and conditions and/or revise the project. Often terms and conditions may be negotiated to meet the goal of the Services and the constraints or needs of the applicant. Step 5. Within 135 days from when the "consultation initiation package"is considered complete,the Services issue a final BO, incorporating any revisions negotiated with the Corps and the applicant during the review of the draft BO. Step 6. Once the BO is issued, the Corps will finalize its permit decision,which will include the BO by reference. If a"jeopardy"BO is issued, the Corps is likely to deny the permit. NOTE: The above timelines for the Services are established in 50 CFR 402. However,the Corps has no authority to enforce these timeframes. Generally,the Corps holds permit decisions until the ESA consultation has been completed. 5 The"complete initiation package"is defined in 50 CFR§402.14(d). 2 coi- 200 `f - DD63S -Tile- .07 Ve ---— _ - Z l c o _ wow 14411160 `fR CITY OF RENTON Planning/Building/PublicWorks Department Kathy Keolker-Wheeler, Mayor Gregg Zimmerman P.E.,Administrator May 27, 2004 Seattle District Corps of Engineers Attn: Regulatory Branch, CENWS-OD-RG Post Office Box 3755 Seattle, WA 98124-2255 Subject: SPIF Form for Near Shore Fill,Nation Wide Permits City of Renton—Maplewood Creek Gravel Replacement Project Dear Gentlemen: The City is applying for the necessary Army Corps permits for adding up to 25 CY of clean gravel to the new channel constructed across the Maplewood Golf Course, as required by the April 30, 2003 Washington State Department of Fish and Wildlife HPA.

Work Description—Describe what type and size of fill will be placed and the amount in cubic yards below ordinary high water: See attached description for overall Project Background and Purpose, 6/28/02 ACE Letter allowing sediment pond cleaning. The April 23,20031HPA issued by WDFW required that the City place up to 25 CY of spawning size gravel in the constructed creek channel downstream of the sediment basin. The new ravel will replace gravel that was placed in the creek when it was originally constructed,and has subsequently eroded downstream or been covered by silt. The specifications for the gravel are shown on the 'For construction description and effects analysis. 1 project drawings. The section between the sediment basin and the flow splitter uses gravel with a maximum 6-inch size(approved by WDFW)to help provide a more stable bottom during higher flows. The section downstream of the splitter structure uses gravel with a 4-inch maximum size since it does not receive the full flow of the creek during larger flood events. All fill will be placed below the OHWL. Construction Techniques—Describe how fill would be placed;how long placement would take;the type of equipment that would be used: The gavel fill may be placed within 2 to 4 days(estimate). In the creek section between the sediment basin and splitter structure the gravel will probably be placed at edge of the creek by hand or a backhoe bucket. The gravel would then be spread by hand shovel over the bottom of the creek. In the section downstream of the splitter structure the gravel will probably be brought to the top of the bank with a small vehicle or wheel barrow. The gravel will be placed by hand shovel in the creek areas below the log drops. 8. Why Doesn't the Programmatic Consultation for"Nearshore Fill"Apply?_ The gavel fill will be placed while water is in the creek, "in the wet". The City requests that the ACE work window for gravel placement be extended to Sept. 15`b to match the work window in the April 23,2003 HPA. Due to heavy usage of the golf course the project to clean the sediment basin and place new gravel in the creek will probably be done at the end of August and beginning of September. 9. Why is the Project"Not Likely to Adversely Affect"Without Meeting all the Conservation Measures or Parameters of the Programmatic Consultation(include Justification/Effects Analysis in addendum if needed). The fill will be new washed gravel so creation of sediment and turbidity should be minimal. Gravel fill will be placed by hand to reduce any disturbance to the existing creek bed. Any sediment created will disperse over the remaining portion of Maplewood Creek(appx. 1000 ft)before reaching the Cedar River. Threatened or Endanger Species will probably not be present in the Cedar R. during project construction. 10. Conservation Measures to be Implemented(check all that apply and will be done): ® This programmatic consultation does not cover activities in the Columbia River Mainstem, including the Snake River and Baker Bay. ❑ Work is done within the approved work window. Requesting an Extension to Sept. 15 ® The material is spread out evenly and the beach grade is not altered(to avoid stranding of fish). ❑ Material is not placed in or within 300 feet of vegetated shallows(except where such vegetation is limited to State-designated noxious weeds)or other special aquatic sites? (?The constructed creek channel may meet the description of a riffle and pool area.) ® Gravel materials are washed and clean prior to being brought to the site. 2 SPECIAL AQUATIC SITES—those sites identified in Subpart E of the Environmental Protection Agency's Guidelines for Specification of Disposal Sites for Dredged or Fill Material(Section 404(b)(1)Guidelines)and include sanctuaries and refuges,wetlands,mud flats,vegetated shallows,coral reefs,and riffle and pool complexes. They are geographic areas,large or small,possessing special ecological characteristics of productivity,habitat,wildlife protection,or other important and easily disrupted ecological values. These areas are generally recognized as significantly influencing or positively contributing to the general overall environmental health or vitality of the entire ecosystem of a region. [40 2 ❑ Work occurs only in the dry. ® Stockpiling shall not occur below OHW or MHHW. ® Work is done by hand except that if a barge is used to deliver material the barge shall not ground out on the bottom. ® Upon completion of material placement the beach shall not contain any pits, potholes, or large depressions. ® All natural beach complexity features that were necessary to remove are repositioned or replaced in their original locations on the beach immediately following completion of the work. 11.

The projects were planned and designed with input from the Washington Department of Fish and Wildlife (WDFW) and Department of Transportation (WDOT). The sediment basin underwent an Environments Assessment as part of the FEMA Grant process. The Army Corp of Engineers approved the reconstruction of Maplewood Creek under Nation Wide Permit 27 issued on March 30, 1998 (Reference: 98-4-00406). WDFW issued an HPA for the construction of each phase of the project. Maplewood Creek flows from highlands north of the golf course to the south, through a wooded ravine, over the golf course, and to the Cedar River. Before the projects were constructed there was an old 8-foot high water supply dam in the ravine northof the golf course, an ineffective sediment basin at the end of the ravine, and a straight channel across the golf course with almost no streamside vegetation. At the south end of the golf course the creek flowed in a 72-inch diameter, 800-foot long, culvert to the Cedar River. In large flood events sediment would erode from the ravine and wash into the channel on the golf course. The channel would fill and floodwaters would spill out onto the golf course and adjacent Highway 169 (Maple Valley Highway). After catastrophic flooding in January 1990, the City applied for and obtained a FEMA Hazard Mitigation Grant, which included removing the 8-foot high water supply dam and the old sediment basin, stabilizing the ravine side slope, and constructing a new sediment basin. In negotiations with the WDFW and WDOT projects were developed to build a new low flow channel across the golf course to provide improved fish habitat, and install fish ladders on the Cedar River and at the new sediment basin to allow fish access to the new section of Maplewood Creek. In 1996-97, the City constructed the new sediment basin at the end of the ravine. The project included removing the old 8-foot high dam and stabilizing the ravine side slopes from the old dam to the sediment basin. The sediment basin has been very effective at stopping sediment from reaching the creek on the golf course and the Cedar River. In general, sediment needs to be removed from the basin every 2 to 3 years. The City has an HPA from WDFW that allows removing sediment through Sept. 15, 2006. In 1999, the City constructed the new low flow fish channel across the golf course, and connected it to the WDOT fish ladder on the Cedar River and a new fish ladder at the sediment basin. The project allows salmon access from the Cedar River to Maplewood Creek. Fish would be able to use the fish ladder to reach the new section of Maplewood Page 1 Creek, instead of having to swim up the old 800-foot long culvert. Because-of large flood flows from Maplewood Creek, and hydraulic capacity limitations of the downstream drainage system, the low flow fish channel had to be designed to convey only low flows from the creek. A flow splitter structure and weir was installed to direct high flood flows to the old channel on the golf course, now referred to as the bypass channel. The flow splitter acts as a second sediment basin and sediments must be periodically removed from it. The new low flow channel across the golf course includes numerous improvements for fish habitat. Log drops were placed in the steeper sections of the channel to help fish passage up the channel and provide deep pools for habitat and shelter. Spawning gravel was placed in the channel, and vegetation was planted along the majority of the channel sides to provide shelter and food sources for fish. Some of the gravel below the log drops and in the low flow channel has eroded downstream or been covered with silt. The April 23, 2003 HPA WDFW required the City to replace up to 25 CY of gravel in the channel between the sediment basin and flow splitter structure, and in the low flow channel. The City is applying to the Army Corps for the appropriate Nation Wide Permits (NWP 18, Near Shore Fill) to allow placement of the gravel required by the HPA.

The permit application indicated that minor amounts of fill material might be utilized to restore channel banks and reinforce the High/Low Flow Splitter. In a letter dated June 24, 2002, you indicated that the proposed work has been revised to include only the excavation of excess sediments. The City of Renton is no longer planning to restore banks or reinforce any structures within the sedimentation pond and no fill material would be placed in waters of the United States. Because fill material will not be placed into waters of the United States and the method of sediment excavation includes clean excavation with a clamshell or backhoe (considered incidental fallback),the Corps has no jurisdiction over the proposed project. Accordingly,the application is canceled. A copy of this letter is also being furnished to the City of Renton Surface Water Utility, ATTN: Mr. Gary Schimek, 1055 South Grady Way, 5ch Floor,Renton, Washington,98055.

Maplewood Creek flows from residential areas on the hillside to the north,to the south through a ravine into the sediment basin. From the sediment basin the creek flows south in a common channel for 280 feet to reach a splitter structure. At the splitter structure low flow is directed into a constructed channel across the golf course. During flood events high flows overflow a concrete weir and go to an overflow channel across the golf course. The low flow channel and overflow channel both flow to the south and drain to the Cedar River at separate locations. In 1996-97 the City constructed the new sediment basin under a FEMA Hazard Mitigation Grant. Sediments were cleaned out of the sediment basin in 1999 and 2002, In 1998 the City constructed the flow splitter structure and improvements to Maplewood Creek, including the new low flow section of the creek across the golf course,log drops,gravel bedding,and creekside vegetation. Maintenance work and gravel replacement has not been performed on the low flow section of the creek since it was constructed in 1999.

IF YOU HAVE PROVIDED ATTACHED MATERIALS TO DESCRIBE YOUR PROJECT,YOU STILL MUST SUMMARIZE THE PROPOSED WORK HERE. ATTACH A SEPARATE SHEET IF ADDITIONAL SPACE IS NEEDED. The City will remove accumulated sediments from the existing sediment basin and flow splitter structure,which does not require a Army Corps permit. On June 28,2002 a letter from the Army Corp stated that a Corps permit was not needed to remove sediment since fill material was not being placed,the method was clean excavation with a backhoe,and the Corps had no jurisdiction over the project(Corps Ref#2002-4-00606, letter attached). The procedures for cleaning the sediment basin are described in the basin's Operation and Maintenance Manual which was approved by the Washington State Dept.of Fish and Wildlife(WDFW). The April 23,2003 HPA issued by WDFW requires that the City place 25 CY of spawning gravel in the constructed creek channel downstream of the sediment basin and flow splitter. The approximate locations and specification for gravel placement are shown on the attached drawings. The section between the sediment basin and flow splitter uses gravel with a maximum 6-inch size(approved by WDFW)to help provide a more stable bottom during higher flows. The section downstream of the splitter stucture uses gravel with a 4-inch maximum size since it does not receive the full flow of the creek during larger flood events. Between the sediment basin and splitter structure gravel will probably be placed at the side of the creek with a backhoe,and will be spread by hand shovel over the bottom of the creek. In the section downstream of the splitter structure gavel will probably be brought to the top of the bank with a small vehicle or wheel barrow. The gravel will be placed by hand in the creek areas below the log drops. PREPARATION OF DRAWINGS: SEE SAMPLE DRAWINGS AND GUIDANCE FOR COMPLETING THE DRAWINGS. ONE SET OF ORIGINAL OR GOOD QUALITY REPRODUCIBLE DRAWINGS MUST BEATrACHED. NOTE: APPLICANTS ARE ENCOURAGED TO SUBMIT PHOTOGRAPHS OF THE PROJECT SITE,BUT THESE DO NOT SUBSTITUTE FOR DRAWINGS. THE CORPS OF ENGINEERS AND COAST GUARD REQUIRE DRAWINGS ON 8-112 X 11 INCH SHEETS. LARGER DRAWINGS MAYBE REQUIRED BY OTHER AGENCIES. 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. Over time the gravel bedding placed in the creek channel between the sediment basin and the splitter structure has eroded and traveled downstream during heavy flood flows. In the April 28,2003 HPA WDFW required gravel placement below the splitter structure and log drops to help restore the creek bed gravel to its conditions and level when the creek was construction in 1999. 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. IDENTIFY WHICH GUIDANCE DOCUMENTS YOU HAVE USED. ATTACH A SEPARATE SHEET IF ADDITIONAL SPACE IS NEEDED. Some temporary increases in water turbidity may occur while placing new gravel in the creek. Any increase from the sediment basin and splitter structure is expected to be slight. All gravel placed in the creek will be clean washed gravel. The gravel will be spread across the bottom of the creek by hand to minimize any sediment that may be stirred up by placement. Any sediment raised by placement is expected to dissipate over the remaining portions of Maplewood Creek before reaching the Cedar River. 7d.

Work shall be accomplished per plans and specifications entitled,"OPERATIONS AND MAINTENANCE MANUAL MAPLEWOOD CREEK SEDIMENT BASIN AND FISH CHANNEL",dated September 1999,and submitted to the Washington Department of Fish and Wildlife(VtDFW), except as modified by this HPA. These plans reflect design criteria per Chapter 220-110 WAC. These plans reflect mitigation procedures to significantly reduce or eliminate impacts to fish resources. A copy of these plans shall be available on site during construction. 3. The sediment basin and fish channel shall he maintained by the City of Renton per RCW 77.55.060 to ensure continued,unimpeded fish passage. If the structure becomes a hindrance to fish passage,the City of Renton shall be responsible for providing prompt repair under this HPA. Financial responsibility for maintenance and repairs shall be that of the City of Renton. NOTE: At the time of the previous WDFW AHB inspection,there was a large angular rock which was installed by the City blocking fish passage midway between the sediment pond and flow splitter which needs to be altered so the blockage is removed. This rock has resulted in an approximate two foot drop,which hinders fish passage. This rock shall be relocated as discussed in the April 29,2003 site review during the allowed timing limitations(Provision 1)prior to September 15,2003. 4. A temporary bypass to divert flow around the work area shall be in place prior to initiation of other work in the wetted perimeter. 5.

A sandbag revetment or similar device shall be installed at the downstream end of the bypass to prevent backwater from entering the work area. 7. The bypass shall be of sufficient size to pass all flows and debris for the duration of the project. 8. Prior to releasing the water flow to the project area, all dredging shall be completed. 9. Releasing of water back in to the pond shall be done slowly, so that approximately 3/4 of the water flows through the bypass until the pond is full,to prevent dewatering of the stream and loss of fish life. 10. Upon completion of maintenance activities, all material used in the temporary bypass shall be removed from the site and the site returned to pre-project or improved conditions. 11. Due to interception of spawning gravels in the sediment basin,spawning gravels shall be supplemented in the fish channel downstream of the sediment basin, as determined to be necessary by the WDFW AHB at the time of each sediment basin maintenance dredging. During the April 29,2003 site review, the WDFW AHB determined that 25 cubic yards of spawning size gravels need to be added to the channel downstream of the sediment pond. Fifteen to twenty cubic yards of this material shall be added downstream of the flow splitter in the pools downstream of the log weirs. 12. The permittee shall capture and safely move food fish,game fish,and other fish life from the job site. The permittee shall have fish capture and transportation equipment ready and on the job site. Captured fish shall be immediately and safely transferred to free-flowing water downstream of the project site. The permittee may request WDFW assist in capturing and safely moving fish life from the job site to free-flowing water,and assistance may be granted if personnel are available. 13. Any device used for diverting water from a fish-bearing stream shall be equipped with a fish guard to prevent passage of fish into the diversion device pursuant to RCW 77.55.040.

Gravel should be sized to become mobile at the bankfull flow event. This can be accomplished using tractive force computations. Refer to the Sediment Transport Appendix for a complete discussion of tractive force and other sediment transport analyses. It may be most practical to use a gradation of gravels with a range of sizes, either due to the practicality of supply availability or to accommodate multiple species requirements. If a gradation of gravel sizes is used,the D50 of the gradation should be sized for incipient motion at the bankfull discharge. Placeholder: discuss how to determine how much gravel to add and how often. Note that this technique relies predominantly on natural process to transport, deposit and sort gravels appropriately, and therefore methods need to focus on identifying where this might be, and place gravel in proximity to this. Placeholder: discussion of where to place gravel should include options for in-channel or on bank, in addition to consideration of proximity to spawning sites. 1.5.2.1 Spawning Habitat Characteristics The characteristics of actual spawning sites vary extensively between species and among stocks of the same species(Table ). Factors such as substrate size,water depth,and water velocity appear to limit where a female is physically able to construct a redd. Body size and stamina determine the size of particles that can be moved,the ability to work in fast water,and maneuverability in shallow water. If there is extensive variation in the size of individual members of a population,differences in velocity, minimum depth,and substrate preferences may be nearly as great between members of the populations as between different stocks or species(Hunter, 1973). Studies indicate that there is a relatively wide range of acceptable conditions for most species(Hunter, 1973). Table X.

Work shall be accomplished per plans and specifications entitled,"OPERATIONS AND MAINTENANCE MANUAL MAPLEWOOD CREEK SEDIMENT BASIN AND FISH CHANNEL",dated September 1999,and submitted to the Washington Department of Fish and Wildlife(WDFW), except as modified by this HPA. These plans reflect design criteria per Chapter 220-110 WAC. These plans reflect mitigation procedures to significantly reduce or eliminate impacts to fish resources. A copy of these plans shall be available on site during construction. 3. The sediment basin and fish channel shall be maintained by the City of Renton per RCW 77.55.060 to ensure continued,unimpeded fish passage. If the structure becomes a hindrance to fish passage,the City of Renton shall be responsible for providing prompt repair under this HPA. Financial responsibility for maintenance and repairs shall be that of the City of Renton. NOTE:At the time of the previous WDFW AHB inspection,there was a large angular rock which was installed by the City blocking fish passage midway between the sediment pond and flow splitter which needs to be altered so the blockage is removed. This rock has resulted in an approximate two foot drop,which hinders fish passage. This rock shall be relocated as discussed in the April 29,2003 site review during the allowed timing limitations(Provision 1)prior to September 15,2003. 4.

A sandbag revetment or similar device shall be installed at the downstream end of the bypass to prevent backwater from entering the work area. 7. The bypass shall be of sufficient size to pass all flows and debris for the duration of the project. 8. Prior to releasing the water flow to the project area, all dredging shall be completed. 9. Releasing of water back in to the pond shall be done slowly, so that approximately 3/4 of the water flows through the bypass until the pond is full,to prevent dewatering of the stream and loss of fish life. 10. Upon completion of maintenance activities,all material used in the temporary bypass shall be removed from the site and the site returned to pre-project or improved conditions. 11. Due to interception of spawning gravels in the sediment basin,spawning gravels shall be supplemented in the fish channel downstream of the sediment basin, as determined to be necessary by the WDFW AHB at the time of each sediment basin maintenance dredging. During the April 29,2003 site review,the WDFW AHB determined that 25 cubic yards of spawning size gravels need to be added to the channel downstream of the sediment pond. Fifteen to twenty cubic yards of this material shall be added downstream of the flow splitter in the pools downstream of the log weirs. 12. The permittee shall capture and safely move food fish,game fish,and other fish life from the job site. The permittee shall have fish capture and transportation equipment ready and on the job site. Captured fish shall be immediately and safely transferred to free-flowing water downstream of the project site. The permittee may request WDFW assist in capturing and safely moving fish life from the job site to free-flowing water,and assistance may be granted if personnel are available. 13. Any device used for diverting water from a fish-bearing stream shall be equipped with a fish guard to prevent passage of fish into the diversion device pursuant to RCW 77.55.040. The pump intake shall be screened with 1/8-inch mesh to prevent fish from entering the system. The screened intake shall consist of a facility with enough surface area to ensure that the velocity through the screen is less than 0.4 feet per second. Screen maintenance shall be adequate to prevent injury or entrapment to juvenile fish and the screen shall remain in place whenever water is withdrawn from the stream through the pump intake. 14. Dredged streambed materials shall be disposed of upland so they will not re-enter state waters. 15. Equipment shall be operated to minimize turbidity. Doing excavation, each pass with the bucket shall be complete. Dredged material shall not be stockpiled in the stream. 16. Dredging shall be accomplished by starting at the upstream end of the project boundary and working downstream. 17. If at any time,as a result of project activities,fish are observed in distress,a fish kill occurs,or water quality problems develop(including equipment leaks or spills),operations shall cease and WDFW at(360)534-8233 and Washington Department of Ecology at(425)649-7000 shall be contacted immediately.

The permit application indicated that minor amounts of fill material might be utilized to restore channel banks and reinforce the High/Low Flow Splitter. In a letter dated June 24, 2002, you indicated that the proposed work has been revised to include only the excavation of excess sediments. The City of Renton is no longer planning to restore banks or reinforce any structures within the sedimentation pond and no fill material would be placed in waters of the United States. Because fill material will not be placed into waters of the United States and the method of sediment excavation includes clean excavation with a clamshell or backhoe (considered incidental fallback),the Corps has no jurisdiction over the proposed project. Accordingly,the application is canceled. A copy of this letter is also being furnished to the City of Renton Surface Water Utility, ATTN: Mr. Gary Schimek 1055 South Grady Way, 5`h Floor, Renton, Washington, 98055.

Sincerely, Gail Terzi, EUeviewTS nalyst Application r Co P y CITY OF REN TON ..at Planning/Building/PublicWorks Department Iesse Tanner,Mayor Gregg Zimmerman P.E.,Administrator June 6,2002 • Ann Uhrich U.S. Army Corps of Engineers- Seattle District Post Office Box 3755 Seattle, WA 98124-2255 SUBJECT: ESA COMPLIANCE—CITY OF RENTON,MAPLEWOOD CREEK OPERATIONS AND MAINTENANCE Dear Ms.Uhrich: This JARPA addresses a maintenance program within the Maplewood Creek system for a Sedimentation Basin and a High/Low Flow Splitter located on the City of Renton,Maplewood Golf Course. These facilities were constructed as part of the Maplewood Creek Fish Channel Project between September 1996, and February 1999. A main purpose of the project was to restore fish habitat in Maplewood Creek. The sediment load in Maplewood Creek is such that these facilities require sediment removal every 2 to 3 years as described in the O&M manual enclosed with this letter. The manual also documents the first sediment removal project, successfully completed in September 1999 with no harmful effects to fish. In an effort to streamline the permitting process,this JARPA is written for a 10-year maintenance program for these facilities using the manual as a basis. With this manual as a basis,the City of Renton is requesting a permit under Nationwide Permit 43—Stormwater Maintenance Facilities to maintain these facilities. The City assumes that no Biological Evaluation or Assessment is necessary for this project and that this JARPA package covers ESA Section 7 compliance. Maplewood Creek flows from the northeast and receives runoff from surrounding development on the upper hillside. Within the Maplewood Creek Golf Course,the stream flows into the Sedimentation Basin and enters a fish ladder. The stream flows back into a restored channel, for about 300 feet,before reaching the High/Low Flow Splitter. At the High/Low Flow Splitter the system separates into the main channel and the high flow channel. The high flow channel,which is normally dry, is the remnants of a constructed trapezoidal channel that once paralleled the entrance to the golf course. The main channel was constructed between August 1998, and February 1999,to restore the stream,provide fish passage,and provide habitat enhancement. The main channel flows into the Cedar River via a Washington State Department of Transportation (WSDOT)fish ladder constructed in 1994. The Cedar River is a major salmon migration waterway for chinook, coho, sockeye, cutthroat and steelhead. Bull trout are rare within the Cedar River. A few salmon have been spotted within the Maplewood Creek system including coho, sockeye and steelhead(Fisher, Larry,WDFW, 21 May 2002,personal communication). The Washington Department of Fisheries Stream Catalogue documents historical coho use in Maplewood Creek. There is no documentation of either chinook or bull trout within Maplewood Creek.Chinook salmon and bull trout are both federally listed as threatened in the Puget Sound area and coho salmon is a candidate species for listing. 1055 South Grady Way-Renton,Washington 98055 R E N T O N 0 This paper contains 50%recycled material,30%post consumer AHEAD OF THE CURVE • Ann Uhrich 6/6/2002 Page 2 Bald eagles, a federally listed species as threatened, do occur around Cedar River were they feed on fish and waterfowl throughout the year. This project does not reduce the food base or disturb any roosting or nesting sites. The maintenance activity occurs approximately 1,200 feet northeast of the Cedar River in a semi-developed area of the golf course. Consequently,the maintenance activity would have no effect on bald eagles. The Sedimentation Basin and High/Low Flow Splitter were designed as integral parts of the Maplewood Creek Fish Channel Project to protect the main channel from high sediment loads and flooding and restore fish passage into Maplewood Creek. If the facilities are not maintained they become filled with sediment, gravel and cobbles and are prevented from functioning properly. Under these circumstances the Sedimentation Basin no longer removes the sediment load from Maplewood Creek increasing TSS levels downstream with harmful effects to redds and benthic macroinvertebrates. Consequent deposition of sediment at the High/Low Flow Splitter changes the hydraulics,diverting the flow from the main channel to the high channel, which could potentially dry up the restored fish habitat in the main channel. Erosion and flooding would also likely occur. In September 1999,the City of Renton Planning, Building and Public Works Department prepared the Operations and Maintenance(O&M)Manual for the Maplewood Creek Sediment Basin and Fish Channel(enclosed). The document presents a detailed procedure for maintaining the facilities requiring rigorous use of BMP's. The manual also includes step-by-step photos of the creation of the sedimentation basin,the HPA issued in September 1999, and lessons learned from the first sediment removal project(City of Renton Memorandum dated October 7, 1999). No harmful effects to fish were documented. The 10-year maintenance program will adhere to the procedures of the manual as well as the recommendations and lessons learned. Because of this,the City anticipates no harmful effect on fish while the facilities are being maintained. If you have any questions or need additional information,please contact Gary Schimek, Project Manager,at 425-430-7205.

This application is intended to cover a 10-year period,from 2002 to 2012,of the operations and maintenance for the Maplewood Creek Sedimentation Basin and High/Low Flow Splitter. Maintenance activities will occur between June 16"and September 151"of the years where this work is necessary. It's estimated that maintenance would be required every 24 years. The work consists of routine maintenance of the existing Sedimentation Basin and the High/Low Flow Splitter. Work within the Sedimentation Basin will include removal of accumulated gravel and sediment. Work at the High/Low Flow Splitter will consist of the removal of accumulated gravel and sediment and adjustments of large rocks and woody debris that may hinder fish passage. The equipment used may include backhoe/excavator,hand tools,vactor truck and flushing pumps. A detailed Operations and Maintenance manual describing procedures for sediment removal is included for reference. Photographs of a sediment removal project at the Sedimentation Basin in September 1999 are included in the manual to document the minimal impact to the system. 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. Flooding occurs in this area due to gradual loss of conveyance capacity. Deposition of sediment at the High/Low Flow Splitter changes the hydraulics of the splitter,causing high flows,erosion,and flooding in the high flow channel.Without sediment removal,the restored main channel could potential dry up.Transport of accumulated sediment increases total suspended solids(TSS)downstream. Periodic removal of sediment is required to maintain the function of the Sedimentation Basin and the High/Low Flow Splitter. 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. Increased sediment transport and turbidity may temporarily impact water quality during the maintenance of the Sedimentation Basin and High/Low Flow Splitter. The procedure described in the Operations and Maintenance manual uses reigorous BMP's and has worked successfully with minimal impact. The sedimentation basin was designed with a flow bypass system to allow runoff to be bypassed around the basin during maintenance work within the basin.
