Assuming maximum build out of the lot (HDR combined with offsite wetland mitigation), this would have create a definate appearance of Conflict Of Interest (COI). After talking with Rebecca, it sounded like that the wetland area was not under consideration for rezoning and thus the impacted area would be farther away from my lot, although I suspect that it would still be close enough to create the appearance of a conflict of interest. In the event that these items make it to the Planning Commission, I will probably excuse myself from participating on them to avoid any appearance of a COI. Lynn Peterson Date: 15 June 2002 MSC: Northwestern Division District: Seattle District SECTION 1135 DETAILED PROJECT REPORT 1. PROJECT: Codiga Farms Intertidal Restoration Project State Congressional District - 09 2. LOCATION: The proposed project is located in Tukwila, Washington, in King County, approximately 10 miles south of Seattle along the Duwamish River. See attached location map (figure 1). The Duwamish River estuary extends from the mouth of the river to River Mile (RM) 14. The name then changes to the Green River and extends another 85 miles to the headwaters in the Cascade mountain range. The Codiga Farms project is located at about RM 10. A map of the project area is included as enclosure 1, a picture of the site is included as enclosure 2. 3. DESCRIPTION OF PROPOSED PROJECT. The purpose of the proposed project is to restore tidal and riverine hydrology to the site in the form of an off - channel slough, estuarine marsh and riparian buffer. The project would improve overbank storage, increase the shoreline length, provide improved estuarine habitat and improve flood plain inundation. The project would create 830 linear feet of side channel rearing habitat for juvenile fish such as chinook and chum and create a small '/2 acre estuarine marsh, which will provide important primary productivity and nutrient export In addition, the project would provide approximately 1.6 acres in riparian and upland planting to provide cover and support wildlife. A perimeter fence will divide the habitat restoration features from the park to help minimize human traffic into the restored area. A proposed path will also help minimize access into the restored area and provide maintenance access to the restored area. The project would also include recreational and educational improvements on an existing 1.15 -acre municipal park. Amenities would include interpretive signage on habitat restoration and historical uses of the area, ari observation platform, paving of a parking lot and installing concrete on a portion of the path for wheelchair access. Project components include: • excavation of two adjoining sloughs (25,000 cubic yards) • placement of rock at the entrance channel and to support slopes (156 cubic yards) • large wood debris with root wads (about 40) • placement of gravel on the channel bottom (250 cubic yards) • creation of an intertidal marsh (about 21,500 square feet and excavation of 13,000 cubic yards of material • perimeter fencing to allow for plant establishment and controlling duck and geese access to the site _ • interpretive signs • an observation platform • a small covered picnic area • seven picnic tables • A portion of the gravel path will also serve as a _hand boat launch are a. • Riparian, upland and marsh plantings An existing barn will be demolished at the site and a small community garden (pea patch) and parking area will be realigned to accommodate the habitat restoration project. How Existing Corps Project Would be Modified. The existing project at Howard Hanson Dam and upstream levee projects would not be directly modified for this project. The project seeks to restore tidal and riverine hydrology, which has been adversely effected by the construction and operation of Howard Hanson Dam and levee projects. The following discusses some of the impacts of the federally authorized and other projects in the basin as well as history of the site under consideration. Basin Impacts The construction of the Tacoma Diversion Dam (in 1910 at RM 61), Howard Hanson Dam (HHD constructed 1960, RM 64), and numerous levees along the river have reduced the migration of the river within the middle and lower basins, affecting sediment transport; and reduced inundation of a significant portion of the historic floodplain. The HHD flood control operation eliminates flows sufficient to cause large -scale shifting or reconfiguring of the channel. Levees confine the river in numerous locations. Except for an area of braided multiple channels near O'Grady Park (RM 36.9 to RM 40.6), much of the river has assumed a single channel configuration. The Corps has constructed levees in the Middle Green River as well as Howard Hanson Dam in the upper basin. Diminished channel length, reduced shoreline length, and considerably less estuary characterize the existing channel conditions in the middle and lower basin today as compared to conditions at the time of European settlement. The following table summarizes some of the physical changes in the system. Additional information on hydraulic changes in the system can be found in the August 2000 Preliminary Restoration Plan. Table -1 -1.

Estimate includes tidal flats, tidal marsh, and tidal swamp. 2. Channel length is calculated for the Green/Duwamish River only. The estimate is from the estuary to the approximate downstream limit of the Green River Gorge at main RM 47.4. 3. Estimate includes some 21,000 feet of the Duwamish straightened during filling of the estuary and approximately 55,000 feet of braided channel and sloughs lost in the middle valley. It is a compilation of information from USGS maps and aerial photos and is an estimate of the maximum active river length for the period 1892 to 1936. 4. Estimate is a comparison of six cross sections within a reach in the middle Green River Valley between the Neeley Bridge at RM 35 and the Whitney Bridge at RM 39. Alteration of the flow regime by HHD and the various diversions of the river's original flows have affected the river in another significant way. Historically, when flows inundated the adjacent floodplains, floodwaters seeped into the floodplain, recharging the water table. This water slowly drained toward the river over the year, supplying small floodplain streams, side channels, and the mainstem of the river with cool flows through the summer low flows. Without floodplain inundation, this process cannot occur, and floodplain streams and side channels dry up earlier in the season. River temperatures may also be affected by the loss of cool groundwater inputs during the summer low flows; ...:.._. Reduced flows have also reduced water supply to the banks and geomorphic surfaces within the active channel. This has reduced overbank storage and affected riparian growth. Reduced soil moisture conditions have been found to lower the growth rate and survival of typical riparian plants. Ultimately this leads to a reduction in riparian width and the eventual replacement of typical riparian plant species with species tolerant of drier conditions. Site History and Impacts. The proposed project seeks to restore some of the habitat losses in the lower Duwamish. Historically, this portion of the Duwamish had a broad and connected flood plain. Within the tidal portion of the flood plain existed estuarine marshes and sloughs. Starting in the 1860's levees were constructed at the marsh edges and these areas were converted to agricultural production such as hop fields. The broad fertile flood plain of the Duwamish attracted many immigrant dairy farmers at the turn of the 20th century. Archie Codiga moved into what was then called Allentown from Switzerland in 1910 and established a dairy farm. The site has been maintained as a farm sirice then, while many.of the adjacent farmlarid'was theri'coiiverted to housing or industry. Prior to 1860, the Duwamish was a flat, meandering river with tidal influence. The Duwamish Estuary was an extensive marsh of over 4,000 acres. This transitioned into a brackish marsh, saltmarsh, and mudflats on the farthest edges of the delta. The main channels were largely unvegetated mudflats and sandflats. Patches of eelgrass were likely present in the saline areas. The historic Duwamish Estuary in the lower basin was largely a detrital -based system and provided significant food and habitat for both terrestrial and marine organisms. Juvenile chum and chinook salmon frequently foraged in sand flat and marsh areas. These prime estuarine wetland and intertidal rearing areas for chum salmon converted high detrital carbon inputs from freshwater flows to forms usable to salmon. These forms included significant insect and crustacean populations in the marsh on which juvenile salmon feed. From a fish and wildlife standpoint, this conversion had harsh consequences. Flow regulation at Howard Hanson Dam, the construction of levees and placement of fill that was put along the margins of the tidal portions of the river interrupted the flow and as a result, nutrient export from the marshes to the adjoining habitats such as mudflats was diminished. Intertidal sloughs that were once refuge areas for juvenile fish (salmon, sculpins, and sole) shorebirds (dunlin, sandpiper and yellowlegs) and waterfowl (pintail, and baldpate) was lost. The continuity of the large interspersed habitats of the estuary became fragmented. This project offers an opportunity to restore some of the former estuary. Alternatives. Four alternatives were evaluated during the combined planning and design study. The following section addresses the measurement of environmental outputs, a description of each alternative and an evaluation of the alternatives based on costs and benefits. An economic evaluation of the recreation project components is also presented below. Environmental Outputs and Costs. Environmental outputs for the alternatives include a quantitative measure of estuarine marsh, riparian buffer and estuarine slough length created under each alternative. Also under consideration is the overall quality of the habitat created. For the scale of project under consideration, this is a qualitative measure to take account of habitat complexity and species diversity as defined below. • Habitat complexity: An interspersion of highly productive and varied habitat types is proposed for this project. This will allow for greater species diversity within the project area than is currently available. More of the life history needs (such as reproduction, feeding and rearing) of this diverse population will be able to occur within the project site which will lessen the need to disperse to other habitats. This will lower predation and expenditure of energy (increase in fitness). 4 • Species Diversity: Sometimes referred to as Biodiversity, it describes the variety of life forms, the ecological roles they perform and the genetic diversity they contain. For this project it is consideration of more than a single species approach. That is, by excluding exotics and invasive species from the project area, benefits (food, refuge or reproduction) will be provided to a variety of organisms. Each of the alternatives under consideration was rated high, medium or low for habitat quality in context of diversity and complexity. Habitat Restoration Alternative Evaluation. The following table summarizes the components and costs of each alternative. The costs in the table only include construction costs, and do not include contingency or S &A. A description and evaluation of each alternative follows the alternative summary table. An incremental cost evaluation provides information to assist in selection of a preferred plan. ALTERNATIVE EVALUATION Table 1: Alternative Outputs and Cost Alternative Estuarine Slough (linear feet) Estuarine Marsh (sq. feet) Riparian Buffer (sq. feet) Municipal Park (sq. feet) Habitat Quality Cost ($1000) No Action 0 0 4,000 50,300 Low $0 Minimal 630 0 4,000 50,300 Low- $784 (5,040 sq ft) Moderate Mixed -use Habitat & Recreation 830 21,500 83,700 44,000 High $883 (Preferred) (6,640 sq ft) Full 1500 43,000 126,000 0 High $1,464 Buildout (12,000 sq ft) 5 • The no action alternative. The no action alternative maintains the current condition and serves as the current baseline condition. For comparison purposes the no action alternative includes 50,300 of parkland, 4,000 square feet of vegetated buffer and 126,700 square feet of degraded riverbank, for a total area at 181,000 square feet or 4.15 acres. • The minimal alternative. This alternative would include excavation of one small slough (630 linear feet multiplied by an 8 foot bottom channel width) or 5,040 square feet) and no estuarine marsh. All interpretive and recreation features (covered picnic area, observation platform picnic tables and parking lot) would be included. For the alternative evaluation, recreational amenities were preliminarily estimated to cost $44,100 and restoration features $740,140. The total restored habitat area is 9,040 square feet, which includes the 5,040 of estuarine marsh and 4,000 square feet of riparian buffer. The cost per square foot of improved habitat area under this option would be roughly $81.86 ($740,000 divided by 9,040 square feet of improved habitat) per square foot. In addition to the high per unit cost of restoration, this option provides only minimal improvement to habitat complexity and opportunity for species diversity • The mixed use habitat restoration and recreation alternative. This alternative proposes to excavate two adjoining sloughs totaling 830 linear feet (6,640 square feet), creation of a'''A acre intertidal marsh (21,000 square feet), and 1.6 acres (83,700 square feet) of riparian planting. This alternative slightly decreases the size of the existing park and provides for educational and recreational amenities. Cost shared recreation features include the interpretive signage, a concrete trail to the observation area, covered picnic area, and parking. Recreational features are preliminarily estimated at $44,100 and include the same elements defined above. A gravel trail will also be provided from the parking lot to the river's edge to provide maintenance access to the restored area, the gravel path will also provide viewing access to the restoration features and serve as a boat launch ramp. This alternative would result in the creation of 111,840 square feet of improved habitat area. The total habitat restoration costs for this option are $839,500, which would be about $7.50 per square foot of improved area. • The full build -out option. This alternative would convert the entire property into intertidal sloughs and estuarine marsh while retaining none of the recreation or interpretive amenities. This alternative creates the maximum habitat benefit area, nearly a fifty percent increase over the mixed -use plan. This plan would create 12,000 square feet of estuarine slough, 43,000 square feet of estuarine marsh and 126,000 square feet of riparian buffer. Total square footage of improved area would be 181,000 square feet. The cost of this alternative is estimated at $1,464,000 resulting in an average cost per square foot of $8.09. The cost increase is primarily due to significant increases in the quantity of material excavated, bank stabilization — material and plantings. 6 The table below presents summary information from the incremental cost evaluation. The alternatives are first sorted by average cost per output, those plans• which produce lower levels of output than the plan with the lowest average cost are eliminated from further consideration. In this case the mixed -use alternative has the lowest average cost per output while the minimal alternative has lower output but a higher average cost per output, as such the minimal alternative is eliminated from consideration. The next step is to compute the incremental costs per incremental output for the remaining alternatives. Alternative Evaluation Table 2: Incremental Evaluation for Restoration Alternative Total Restoration Costs (X $1000) Total Habitat Restored Average Cost per Output Incremental Cost per Incremental Output No Action $0 0 $0 n.a. Mixed -use Habitat & Recreation (Preferred) $883 111,840 $7.50 $7.50 Full Buildout $1,464 181,000 $8.09 $8.40 Minimal $740 9,040 $81.86 Eliminated from evaluation Based on the cost effectiveness and incremental evaluation, either the mixed use plan or the full build out plan is incrementally justified. Although the full build out alternative provides the greatest increase in improved habitat, approximately a 32% increase compared to the mix use plan (137,000 square feet under the mixed -use plan compared to 181,000 square feet) and the incremental costs per output are not substantial, the added implementation costs of this option are not judged to be "worth it ". In addition, this limited evaluation does not include the value of the loss of the park. Additionally the non - federal sponsor is not willing to support a habitat restoration project that would include the loss of the park. Based on this evaluation the federally recommended alternative and the alternative supported by the non - federal sponsor is the mixed -use plan. 7 Recreation Evaluation. In accordance with_EP 116.5 -2 -502, recreation components of ecosystem restoration projects must meet several criteria. They must be economically justified, cannot increase the overall ecosystem project cost by more than 10 %, cannot impact or reduce the restoration outputs and must be provided on the lands needed for the basic ecosystem restoration project. Exceptions to the last criteria are where lands may be needed for parking, public access and health and safety features. Costs. The recreation features that are proposed for inclusion in the Codiga farms project include signage, parking improvements, picnic tables, a picnic shelter and a viewing platform. The preliminary cost estimate for these items is $44,000. Average annual costs based on a 50 -year project life and the federal discount rate for 2002 of 6.125% are $2,840. Benefits. The Unit Day Value Method (UDV) was used for the economic evaluation. This method assigns a value per use based on the willingness to pay of users. The value is determined based the overall recreation experience at the site, the availability of other similar recreation opportunities in the area, the carrying capacity of the site, the site accessibility, and the esthetic value of the site. Based on the generalized scoring system in EGM 01 -01, the existing condition score for the site was assessed and determined to be 15 corresponding to a general recreation value of $3.53. With the project in place the score increases to 48 which corresponds to a value of $5.85. The City of Tukwila does not track annual usage of the existing site, however use information is available for the Pea Patch at the site. This information combined with estimates for expected increases in park usage can be compared to recreation costs to determine the projects economic viability. The existing site use under current conditions is primarily by individuals who use the existing pea patch. Based on use over the past five years, an expected 20 individuals will participate in the pea patch program. Based on this information, it is assumed that at least 20 individuals:will•visit. the-site an estimated 10 times per year for a total annual use of 200 days. This will serve as the existing condition usage estimate. Based on this information, the usage is multiplied by the existing condition value of $3.53 to arrive at the annual recreation value of $706. Park usage is expected to increase with the added recreational amenities at the site. Existing pea patch program participants are expected to continue using the project, but the unit day value will increase for these individuals. New users to the park are also expected. If we assume that the added amenities to the park would attract 15 additional users per week between May and October and an additional 2 people per week between November and April the total annual user days is 642. This usage multiplied by the increased value with the project in place of $5.85, results in a total annual value of $3,755._ 8 Based on this information the net annual increase in value over the existing condition is $3,049: This figure represents a conservative estimate of recreation project benefits. The benefit figure is divided by the annual costs to arrive at a benefit to cost ratio. The benefit to cost ratio is calculated to be 1.1. The proposed recreation amenities at the site are economically justified. Project Benefits. By restoring flood plain connectivity and intertidal habitats (i.e. small blind channels, mudflats, intertidal marsh) a variety of benefits could be expected. The following are three of the most important considerations: • The Codiga Farm area would be restored to a more historic condition. By doing so, both primary and secondary productivity at the site would be increased. By restoring habitat types that produce the basic food sources (such as organic carbon, detritus, and benthic and epibenthic organisms) at the base of the food chain, the benefits will be realized throughout the trophic structure. This restoration would also facilitate nutrient exchange as well as provide better fish access. • As a result of restoring several habitat types (mudflat, tidal slough and marsh) and establishing functional connections between the watershed and estuary, the restoration work would also - significantly increase the species diversity at the project site. Many of these species are sensitive species or are currently in decline in the region due to development and loss of habitat. • Also as a result of restoring a complex and interconnected system, the restoration work would provide better support at critical life stages to the more diverse species assemblages that could now utilize the site. These life stages include reproduction, rearing, feeding, refuge, immigration, and emigration. The site also offers one of the few off- channel refuge areas during high flow events in many miles. Target species that would most benefit from this potential project include many species of fish, birds, and mammals. Fish species include juyenilesole, sculpins, stickleback, chum salmon, chinook salmon, and cutthroat trout. Bird species include geese, goldeneye, coot, gadwall, bufflehead, merganser, great blue heron, green- winged teal, killdeer, mallard, sandpipers, dunlin, goldfinch, juncos, osprey, redtail hawk, bald eagle, redwinged blackbird, and song sparrows. Mammal species include river otter, raccoon, and muskrat. The increase in shallow water habitat would probably benefit chinook and chum salmon the most and these important species have been in serious decline in the Puget Sound basin within the past few decades. Puget Sound chinook has been listed as a threatened species under the Endangered Species Act. The following table describes the physical changes in habitat that can be expected if construction is completed. 9 Table 1 -2 Project Habitat Benefits Physical Change in: Pre - Project Condition Post Project Condition 21,500 sq. feet Estuarine Marsh 0 Riparian Buffer 4,000 sq. feet 83,700 sq. feet Estuarine slough length 0 linear feet 830 linear feet Importance of the proposed outputs. Specific species that would benefit include the Washington State sensitive species such as great blue heron, the federally threatened species American bald eagle, and significant species that are regionally in decline such as dunlin, goldeneye, and gadwall. The project site would provide overwintering habitat for the common merganser and nesting sites for the spotted sandpiper. Several salmon and trout species would especially benefit from this project as well. These include the threatened Puget Sound chinook, and churn salmon, steelhead and cutthroat trout. If residence time is increased due to the feeding and refuge opportunities afforded by this project, the salmon would be larger and more fit as they migrate to the ocean. This would increase their survival rate during their long migration prior to spawning. Many salmon species in the Northwest are currently in severe decline and have been petitioned for endangered species status. Currently chinook is listed and bull trout is proposed for listing. The wild stocks of salmon and trout in Duwamish/Green Basin are but a small fraction of their historic numbers. Relationshi. of .ro.osed .ro'ect to other .ro'ects and .lans. Several agencies have been working cooperatively to restore the Duwamish estuary. There is currently a Coastal America demonstration project within the estuary. This demonstration project was completed in late 1994 and is similar in scope to the potential Section 1135 project in that it too involved the removal of material to restore the shoreline to its natural shallow water habitat. This new project that is being proposed under Section 1135 would further develop the partnerships fostered in the original demonstration project and would benefit from the lessons learned. Additionally, working with King County (under the 1135 program) -and the =Fort of Seattle (under 206 authority); two other-estuarine habitat projects have been constructed further down stream. This project would have a cumulative beneficial effect for those projects. The Codiga Farms project is a "spin -off, early action project" of Seattle District's ongoing Green/Duwamish Ecosystem General Investigation Study (G.I.). The Codiga Farms project received one of the highest project rankings of any of the projects evaluated in the G.I (over 50 projects were evaluated). This project is consistent with the goals and objectives established in the G.I and address many of the limiting factors of habitat productivity that were established under the G.I. (estuarine loss, off - channel feeding and rearing opportunities for juvenile salmonids). Lands, Easements and Rights of Way (LER). - Approximately 4.13 acres of land is required for the proposed Section 1135 Project. The city of Tukwila, one of the two Non - Federal Sponsors already owns fee interest to 4.11 10 acres of which 3.10 acres of fee interest is necessary for the proposed restoration project, ---with an estimated value of $147,000. Washington State Department of-Natural - Resources (DNR) a co- sponsor owns the additional 0.02 of an acre in public trust, necessary for the proposed restoration project, which it will make available for the project. The value of the DNR land is considered nominal. Access to the site is from an existing public road. During construction the City of Tukwila will also make available 1.01 acres for a strip of land between the public road and a portion of the permanent Section 1135 project site for a temporary staging area, with final further improvement to a section of this area for construction of a parking lot as part of a recreation feature outside the Section 1135 permanent project footprint. Since there is no loss in utility to the ecosystem project if the parking lot was not built or a loss in utility if the recreation feature is built without the ecosystem project, the parking lot is viewed as a stand -alone item that the City could choose to relocate in the future if necessary. So the City will only receive credit toward its cost -share requirement for the temporary work area easement, including the parking lot area within the temporary work area footprint for the purposes of the Section 1135 project. The estimated value of this temporary right is $7,000. See the project drawing for the location of these items. Following is a summary of the estates and estimated fair market value by each estate proposed for implementing the Section 1135 project. TABLE I ESTATE Fee Temporary Work Area Easement (15 months) Subtotal Contingency 25% TOTAL ACRES 3.12 1.01 4.13 4.13 ESTIMATED FAIR MARKET VALUE $147,000 7,000 $154,000 38.500 $193,000 (rounded) -Real Estate Baseline Cost Estimate - Before advertising for project construction both the City of Tukwila and Washington State, Department of Natural Resources will need to certify their LER available for construction. See Table II below for the real estate cost estimate for this proposed project. The cost includes an estimated fair market value of the lands to be provided for the project and administrative costs for certifying their LER available and any acquisition costs, (e.g. incidental acquisition costs, such as title, survey, appraisal costs, negotiations, recording fees, legal fees, etc) if the lands were acquired within a five -year period of the date the Project Cooperation Agreement is signed. The Federal review and assistance costs are estimated at $12,000 and include providing Non - Federal Sponsors with LER requirements, review of appraisals, coordination meetings, review of right -of -way documents, legal support, crediting activities, etc.). 11 TABLE E -II FEATURE CODE 01 LANDS AND DAMAGES Lands and Damages $193,000 Non - Federal Sponsor's Costs 28,000 Subtotal of Sponsor LER Credit $221,000 Federal Review and Assistance Costs 12,000 TOTAL LER (includes 25% contingency) $233,000 4. CONSISTENCY STATEMENT: The project modifications would be consistent with the authorized Howard Hansen Dam project and would in no way adversely impact the project. 5. VIEWS OF SPONSOR: The city of Tukwila will act as the non - Federal sponsor for cost - sharing purposes for this project. Washington State, Department of Natural Resources also acting as a non - Federal Sponsor with limited participation to only providing their LER. The city has expressed a strong interest in and commitment to restoring the biological productivity of Codiga Farms. Their letter requesting assistance, dated January 25, 2000 is attached as enclosure 4. The city and Washington State and the Department of Natural Resources are in agreement with the project as described in this fact sheet. The City of Tukwila is in agreement with the estimated implementation cost and has set aside funding for the project in their capitol improvement program budget for 2002. By letter dated 28 February 2002, the sponsor has outlined their understanding of their responsibilities under the program, including cost - sharing and agreement with the terms of the PCA, and indicates their continued support for the project. 6. VIEWS OF FEDERAL, TRIBAL, STATE, AND REGIONAL AGENCIES: There is strong interest in and commitment to achieving the goals of this potential restoration project amongst state and Federal resource agencies. During project development and planning, District staff worked closely with representatives of the Muckleshoot Indian Tribe to identify "and address cultural issues relating to the property. Tribal representatives participated fully in the Green Duwamish General Investigation study under which the Codiga Farms 1135 was initially proposed. The Tribal representatives also participated in the decision to go ahead with Codiga Project under the section 1135 program, and not the larger Green/Duwamish Ecosystem Restoration Project. Tribal fisheries staff were consulted during the preparation of the EA and FONSI, and offered no comments during the public comment period. Seattle District Staff archeologists surveyed the site for native artifacts, and coordinated the finding with both the Tribe and the SHPO. To date, the Tribal representatives have provided continued input, and have not given written indication of unanswered concerns. Seattle District ERS will continue to coordinate with the Tribe during the construction and monitoring phases of the project. 12 7. STATUS OF ENVIRONMENTAL COMPLIANCE: This project is compliant with all applicable regulatory requirements. An Environmental Assessment, 404(b)(1) analysis, water quality certification, Coastal Zone consistency and a Biological Assessment have been completed for the project. Under section 404 of the Clean Water Act, Nationwide permit 27 applies. The FONSI was signed 4 September 2001 and the HPA was received 23 July 2001. Endangered Species Act compliance is being met through the Programmatic. Biological Assessment (June 2000) prepared for the Green - Duwamish Ecosystem General Investigation Study. Concurrence letters for the Codiga Farms Project were received 10 April 2001 from the NMFS and on 10 March 2001 from the USFWS. All environmental compliance is complete. 8. COSTS AND BENEFITS: The benefits associated with implementation of this project will outweigh the project costs. The project will result in ecosystem benefits to a variety of organisms and increased biodiversity. The recommended plan is the NER plan and the plan supported by the non - federal sponsor. 9.

SUPPLEMENTAL INFORMATION: • In -kind Services. The local sponsor has indicated that they wish to perform ., limited in-kind services, in the form of materials_ and equipment.:This, effort. is estimated to be $146,000. • Monitoring. There will be monitoring associated with this project. Monitoring is needed to ensure both biological and functional effectiveness. Monitoring will be focused on the factors that are targeted for improvement. In years one, three and five we will monitor: plant survivability (percent cover), fish use (primarily juvenile salmon), prey resource production, and cross sectional area at the mouth of the slough where it meets the Duwamish River. Estimated monitoring is expected to be $45,000 total for the project ($30,000 biological and $15,000 physical). Note the monitoring cost represent about 3% of the total budget. Additional documentation on the unique demands for monitoring can be found in the August 2000 Preliminary Restoration Plan. Approval for the additional . monitoring was provided in earlier documentation._ • Co- sponsor. A deviation to the model PCA is being requested. A portion of the entrance channel is under Department of Natural Resources (DNR) jurisdiction. The City of Tukwila and the Washington Department of Natural Resources will 13 act as non - federal sponsors. The DNR parcel is estimated at 0.02 of an acre (640 square feet), more or,less as documented on :Plate G -2.of the project. drawings. based on 2' contour information. Design and construction requirements specify that the channel must extend from elevation 0' to —2' (N.G.V.D., 1929) and be of sufficient width to allow for construction and maintenance of the backwater channel and re- vegetation of the area. • Project Costs. The project will be conducted through an equipment rental contract, District Emergency Management staff has reviewed the project cost estimate. • Technical Documentation. Additional project documentation related to the hydrologic design of the project, HTRW investigations, and geotechnical evaluation is available at the District. • HTRW Investigations. HTRW investigations found that a portion of the barn removal (lead paint on the milk barn, and asbestos on several windows) and soil removal related to a waste oil spill are not eligible for cost sharing in accordance with ER 1165 -2 -132. The Corps has estimated the amount not eligible for cost share is $17,000. The sponsor as an in -kind contribution will complete barn demolition and disposal. The sponsor will be required to demonstrate to the Corps that all CERCLA hazardous material has been removed from the site, including confirmation sampling of the soil. • Financial Capability. The City of Tukwila, the project sponsor for all financial considerations, has demonstrated their financial capability to implement the project. The City has set aside $100,000 in their 2002 budget to meet their required cash contribution and to fund several work -in -kind items to be contracted. The remainder of the non - federal share will be comprised of work -in- kind, performed by in -house staff and provision of necessary real estate. • Historical Preservation. As indicated by a MOU signed by the Corps and the SHIPO, Historical documentation of the barn is required. Estimated costs for this item are $13,000 and will be a 100% federal responsibility in accordance with the provisions of P. L. 93 -291, the Archeological and Historic Data Preservation Act.

Army Corps of Engineers on the restoration sites being funded by that agency. • Environmental Checklist and ESA Screening Checklist prepared by the applicant Summary of Primary Impacts: Earth The soils at the proposed building site are glacial till, sand and gravel covered by approximately 2 feet of topsoil. The site is generally flat with the steepest slope being 3 -5% along the river bank. The site is not leveed on this side of the river bank. The western portion of the site is currently used as a pea patch for city residents. The. pea patch will be reoriented and enlarged as part of the overall project. A significant amount of excavation will take place on the site since the project is to create a salmon habitat side channel. It is estimated that 15,000 to 22,000 cubic yards of excavation will occur. Some of the excavated soil will be used to grade the site. The remaining will be hauled to a legal disposal site or appropriate fill location. Approximately 5% of the site will be covered with impervious surfaces after project completion. Best Management Practices will be used, as required by the 1998 King County Surface Water Design Manual, to minimize erosion and offsite sediment transportation. Air Normal emissions and dust associated with use of construction equipment will occur during construction of the project. Emissions will conform to P.S.A.P.C.A. requirements. Water The Green/Duwamish River abuts the site. The purpose of the.project is to add a 800 foot side channel to the River to restore juvenile rearing habitat. The project is subject to the State Shoreline Management Act. A Hydraulics Project c:\mydocs \Codiga Farm \SEPA- staffrpt.doc 2 SEPA Review = E01 -007 • • Codiga Farm Side Channel May 8, 2001 Approval (HPA) permit is required from the state Department of Fisheries and Wildlife since work will be done waterward of the ordinary high water mark; a U. S. Army Corps of Engineers 404 permit is also required for the project. Approximately 600 cubic yards of material may need to be removed in order to connect the completed side channel with the River. The finished project is intended to allow the river to back fill into the side channel. Water depth and quantity will fluctuate with the elevation of the River. The project is within the 100 year flood plain. The flood plain elevation is approximately 12.5 feet. The parking area will be paved either with concrete or asphalt. Runoff from the parking area will be routed into a bioswale for treatment and infiltration, per the requirements of the King County Surface Water Design Manual (K.C.S.W.D. Manual). All requirements of the K.C.S.W.D. Manual will be met for this. project. Plants Currently there are alder, maple and fir trees on the site along with shrubs, grass and pasture. All invasive vegetation will be removed and the side channel will be planted with native terestrial and aquatic species to improve the habitat value of the side channel. Animals The SEPA Checklist notes that hawks, herons, eagles, songbirds, and most bird species found in Western Washington have been observed on or near the site. The site is located along the Pacific Flyway migration route. The mammals observed on the site have been river otter, mice and voles. The River provides habitat for salmon, trout and shellfish. Energy/Natural Resources Electricity will be used to power a light in the parking lot. The light will be regulated by photocells, on at dusk and off at dawn. Environmental Health No environmental health hazards are expected as a result of this project, nor is the project expected to increase the need for emergency services. The project 3 c:\mydocs \Codiga Farm \SEPA- staffrpt.doc SEPA Review — E01 -007 Codiga Farm Side Channel May 8, 2001 Light/Glare The only exterior lighting will be a pole light illuminating the parking lot for security purposes. The light will be controlled by photocells, which will turn the light on at dusk and turn it off at dawn. No glare from the parking lot light is anticipated on the adjacent residential area. Recreation As part of the park components of this project a hand held boat launch will be installed along with a picnic shelter and pathway with observation platform that allows visitors to look out over the side channel. Interpretive signs will be installed to explain both the value of side channels in the life cycle of salmon and the agricultural history of the site. Historic /Cultural Preservation The site has been used since 1929 as a dairy farm and contains the only remaining barn in the City. The barn and its associated structures as well as the landscape have been deemed eligible for the State Historic Register. The applicant and the U.S. Army Corps of Engineers are working with the State Historic Preservation Office to determine what mitigation will be required for demolishing the buildings. The applicant expects to photo - document the site and some of these photos will be used as part of the interpretive signage. Demolition of the barn and other structures is needed given the design of the side channel to maximize its habitat restoration value. The Corps is also investigating the archeological significance of the site. The Tukwila Historical Society has offered to assist with the text for the interpretive signs. The proposed design of the signs mimics the architecture of the barn. Transportation The site is accessed via 50th Place South. Currently there is a gravel parking lot that provides parking for 8 cars for the pea patch. The parking lot for the project will be shared with the pea patch. The Parks Department has provided a memorandum documenting the anticipated parking needs for the site. Parks staff recommend that 12 parking stalls be provided, based on their standard requirement for this type of park of 3 parking stalls per acre of neighborhood park site with active amenities. This site is approximately 3 acres with a mix of active and passive park facilities. The majority of the site will be used for the side channel fish habitat restoration, with the active features including a c:\mydocs \Codiga Farm \SEPA- staffrpt.doc SEPA Review — E01 -007• Codiga Farm Side Channel May 8, 2001 community garden, covered picnic shelter, fish observation deck, walking trail and non - motorized boat launch. A portable toilet will remain on the site. The site plan indicates that 12 parking stalls plus one ADA stall for a total of 13 parking stalls will be constructed. Public Services The development of this site as a small park and fish restoration project may generate an increased need for public services such as police and fire. The Police Department has reviewed the project and recommended that a pay telephone be installed in the event there is an emergency on the site and that the parking lot be lighted. Utilities Utilities currently available at the site include electricity and water. A portable toilet is provided in lieu of full restroom facilities. No additional utilities are anticipated to be needed as a result of the park construction.

GRID • DEPARTMENT OF COMMUNITY DEVELOPMENT EXECUTIVE SUMMARY April 16 - April 20, 2001 OTHER Codiga Farm Side Channel Project An Open House was held Wednesday, April 18, from 5:00 -7:00 p.m. at the Community Center to present information about the Codiga Farm Side Channel project. Staff from Public Works, Parks, Community Development and the U.S. Army Corps of Engineers attended to answer questions of area residents. Five area individuals attended, including former City Council member Wendy Morgan, who attended as President of the Tukwila Historical Society. While not many people attended, those who did come had a number of issues they wanted to discuss. These concerns included the following: plans for including a pay telephone at the site (suggested by the Tukwila Police Department in case of an emergency involving the boat launch) will be a magnet for drug dealers who already are a strong presence in this neighborhood; if the pay telephone is placed there, then surveillance cameras should also be installed on the site; the park should be gated so that it doesn't attract nuisance activity at night; the porta -potty is used for illegal activities and should be removed; there needs to be more presence by the police department in this area; the park should not be named after the Codiga Farm (there is already a bridge named for Mr. Codiga) but a name representing a broader community should be used. Concern was also expressed about the number of abandoned vehicles and trash that has collected around and under the bridge. The Historical Society was concerned that the barn is being torn down with no real effort to preserve it and that they were not notified directly about the meeting but found out about it at the Council meeting this week. Ms. Morgan offered the assistance of the Historical Society with writing the text for the interpretive signage on the site. The Society requested copies of pictures of the barn and the original architectural drawings for their archives. Parks Department staff will follow up with the Historical Society to develop the interpretive signage. Staff will also discuss the safety issues raised with the police department. Steve Lancaster, Director, Department of Community Development • • Automobile Parking Regulations and Policies Parking of automobiles can be divided into two use groups: 1. Parking as an accessory use - whether it's for a residence or a business. The parking is there because the business or residents want to provide on -site space for cars as a courtesy /necessity for visitors, employees, or owners. 2. Parking as a primary use - there is no other primary use of a site other than the parking of cars. There may or may not be a fee charged to use the parking space. This type of parking as a primary use can provide a service for businesses within walking distance or for some distant use. Parking as a primary use can provide: • riders for a transit system • publicly subsidize parking spaces for urban centers • reduction in the number of auto trips into congested areas such as urban centers, airports, etc. • dispersal of automobile parking to sites outside of congested areas • • an economic use of land • potentially less auto trips among neighboring sites 1995 Comprehensive Plan (amended) Relevant Policies on Public Parking Lots and garages 8.1.16 Support multi -modal transfer areas for cars, buses, pedestrians and rail. 13.4.14 Support short and long term use of rail, carpools, buses 13.3.3 Support street capacity improvements and trip reduction (trip generation control) measures as means to control street network capacity. 13.6.4 Work with King County and Port of Seattle in controlling adverse impacts from airport operations and development.

UNITED STATES DEPARTMENT OF COMMERCE National Oceanic and Atmospheric Administration NATIONAL MARINE FISHERIES SERVICE Northwest Region 7600 Sand Point Way N.E., Bldg. 1 Seattle, WA 98115 April 10, 2001 ATTACHMENT F Dear Colonel Graves: This correspondence is in response to your request for consultation under the Endangered Species Act (ESA). Additionally, this letter serves to meet the requirements for consultation under the Magnuson- Stevens Fishery Conservation and Management Act (Magnuson - Stevens Act). Endangered Species Act The. National Marine Fisheries Service (NMFS) has reviewed le August 31, 2000 request for concurrence with your findings of "may affect, not likely to adversely affect (NLAA)" for the above referenced program, based on the Programmatic Biological Assessment (PBA, June 2000), Final Feasibility Report (October 2000), and Supplemental Letter (March 27, 2001). Your findings in regard to the listing of Puget Sound chinook salmon (Oncorhynchus tshawytscha) as Threatened under the ESA. This consultation with the United States Army Corps of Engineers (ACOE) is conducted under section 7(a)(2) of the ESA, and its implementing regulations, 50 CFR Part 402. The NMFS has evaluated the 50 projects in this ten -year program directed at ecosystem habitat restoration and enhancement, largely for salmonids and especially Chinook salmon, and concurs with your findings of "may affect, not likely to adversely affect," to either the species or the designated critical habitat for most of the projects (See Table 1). Based on the ACOE's Supplemental Letter of March 27, 2001 to the PBA, NNS agrees with the assignment of the projects into four groups: early action (Calendar Year 2001), Phase 1 projects (Years 2002- 2003), Phase 2 (Years 2004 - 2009), and those that require an individual consultation or reinitintion under this consultation, based on requiring more detailed construction plans.

' Culvert replacement projects will use NMFS' Guidelines for Salmonid Passage at Stream Crossings, Final Draft, March 28, 2000 (Appended). Those restoration projects in which NMFS concurs provide an increase in quantity of critical and essential fish habitat though the removal of upland fill and the removing of fish passage impediments and an increase in quality of the critical and essential fish habitat because of the reasons provided in your Biological Assessment and Supplemental Letter: 1) the work will be done during a time of the year when chinook salmon are not present; 2) most of the upland • construction will take place "in the dry" with final connection to the aquatic environment during permissible periods, 3) the implementation employs a landscape ecological approach for the entire watershed from the headwaters of the Green River through the Duwamish estuary to marine habitats in Elliott Bay shallow subtidal substrates; 4) these projects will complement other ongoing Green- Duwamish River Basin restoration and mitigation efforts; and 5) the project will meet all of the Washington Department of Fish and Wildlife Hydraulic Project Approval conditions, This concludes informal consultation on these actions in accordance with 50 CFR 402.14(b)(l). The ACOE must reinitiate this ESA consultation if:• 1) new information reveals effects of the action that may affect listed species in a way not previously considered; 2) the action is modified APR 23 '01 12:05 NNES ' - THNEST REGION P.5 /7 -4- in a manner that causes an effect to the listed species that was not previously considered;. or 3) a new species is listed, or critical habitat designated, that may be affected by the identified action. Essential Fish Habitat Federal agencies are obligated, under Section 305 of the Magnuson- Stevens Fishery Conservation and Management Act (IvISA) (16 USC 1855(b)) and its implementing regulations (50CFR600), to consult with NlvfFS regarding actions that are authorized, funded, or undertaken by that agency, that may adversely affect Essential Fish Habitat (EFH). The MSA 03) defines EFH as "those waters and substrate necessary to fish for spawning, breeding, feeding, or growth to maturity." Furthermore, NMFS is required to provide the Federal agency with conservation recommendations which minimize the adverse effects of the project and conserve EFH. This consultation is based, in part, on information provided by the Federal agency and descriptions of EFH for Pacific coast groundfish, coastal pelagic species, and Pacific salmon contained in the Fishery Management Plans produced by the Pacific Fisheries Management Council. The proposed actions and action areas are described in the Biological Assessment. The action area covers four different types of habitats: marine, tidally- influenced estuarine, and riverine. The marine habitats contain designated EFH for various life - history stages of 46 species of groundfish, 4 coastal pelagic species, and three species of Pacific salmon; the estuarine habitats contain designated EFH for various life- history stages of 17 species of groundfish, four coastal pelagic species, and three species of Pacific salmon; and the riverine habitats include designated EFI-I for various life - history stages of three species of Pacific salmon (Table 2). Information submitted by the ACOE in the Programmatic Biological Assessment is sufficient for NMFS to conclude that the proposed action may adversely impact EFH in the short term by: 1. Increased siltation during in -water construction operations; and 2. Release of previously unknown chemical contamination during construction. EFfI Conservation Recommendations: The conservation measures that the ACOE included as part of the proposed action are adequate to minimize the long -term adverse impacts from this project to designated EFH for the species in Table 2. It is NMFS' understanding that the ACOE intends to implement the proposed activity with these built -in conservation measures that minimize potential adverse effect to the maximum extent practicable. While NMFS is satisfied with the nineteen General Best Management Practices (BMPs, in Section 2.5) in the PBA, short -tern impacts should be minimized with the following recommendations. 1. Where gravel/cobble material is to be used in gravel replacement projects, it will be sieved (screen) to remove fine - grained materials smaller than 1/4" in diameter (BMP #15). It is assumed projects will require some level of maintenance over time; this should not include in -water dredging of sediments. APP. 23 '01 12:06 NMFS t THWEST REGION P.6'7 2. Construction activities will cease if chemical contamination found at any site exceeds the State of Washington sediment standards or Model Toxics Control Act, where applicable (BMP #16), until the contamination is either removed or the project abandoned. Please note that the MSA ( §305(b)(4)(B)) requires the Federal agency to provide a written response to NMFS' EFH conservation recommendations within 30 days of its receipt of this letter. This concludes EFH consultation in accordancc with the MSA and 50CFR600. The ACOE must reinitiate EFH consultation with NMFS if the proposed action is substantially revised in a manner that may adversely affect EFH, or if new information becomes available that affects the basis for NMFS' EFH conservation recommendations (50 CFR 600.920(k)). This concludes ESA and EFH consultations. If you have questions regarding either of these consultations, please contact Robert Clark at 206- 526 -4338.

Dear Colonel Graves: This correspondence is in response to your request for consultation under the Endangered Species Act (ESA). Additionally, this letter serves to meet the requirements for consultation under the Magnuson - Stevens Fishery Conservation and Management Act (Magnuson - Stevens Act). Endangered Species Act The National Marine Fisheries Service (NMFS) has reviewed fHe August 31, 2000 request for concurrence with your findings of "may affect, not likely to adversely affect (NLAA)" for the above referenced program, based on the Programmatic Biological Assessment (PBA, June 2000), Final Feasibility Report (October 2000), and Supplemental Letter (March 27, 2001). Your findings in regard to the listing of Puget Sound chinook salmon (Oncorhynchus tshawytscha) as Threatened under the ESA. This consultation with the United States Army Corps of Engineers (ACOE) is conducted under section 7(a)(2) of the ESA, and its implementing regulations, 50 CFR Part 402. The NMFS has evaluated the 50 projects in this ten -year program directed at ecosystem habitat restoration and enhancement, largely for salmonids and especially Chinook salmon, and concurs with your findings of "may affect, not likely to adversely affect," to either the species or the designated critical habitat for most of the projects (See Table 1). Based on the ACOE's Supplemental Letter of March 27, 2001 to the PBA, NMFS agrees with the assignment of the. projects into four groups: early action (Calendar Year 2001), Phase 1 projects (Years 2002 - 2003), Phase 2 (Years 2004 - 2009), and those that require an individual consultation or reinitiation under this consultation, based on requiring more detailed construction plans. Five projects during Phase 1 are considered Demonstration Projects which will provide information on huw to better implement larger scale projects planned for Phase 2 which ultimately occur at Printed on Recyclul Paper MM 0 9 2001 TU° VR ..A PUBLIC WORKS consultation with these agencies and has supplied each of them with a programmatic biological assessment for the Ecosystem Restoration Study. This procedure was identified in the Restoration Plan. These documents, each over 125 pages in length, are considered to long to be included in the Final EIS. They are available from the Services that have jurisdiction for ESA issues. No additional information on ESA compliance will be included in the Final EIS. Green/Duwamish River Basin Restoration Program Final Programmatic EIS • They occur on lands that were purchased with recreation funds or the lands were purchased for the purpose to provide shoreline and public access prior to any suggestion of aquatic habitat restoration. Public features in some restoration projects is not a unique concept, there are a few sites in the Duwamish Estuary where habitat features have been incorporated into parks. The T -105 area that is owned by the Port of Seattle and Seaboard Lumber site that was constructed by the City of Seattle Department of Parks and Recreation are two such examples. Many shoreline master plans discuss the importance of public access to the States shorelines. Some public grants place an emphasis on providing some public access to publicly acquired lands. The more important question is what is the best way to accomplish this without jeopardizing the objectives of the restoration activity. The above mentioned projects are but two examples on how this can be accomplished. There are only a handful of projects where trails or viewing platforms are proposed. Additional analysis "to assess the impacts to sensitive habitats" is not needed since these properties, in the most part have already been purchased and the public currently has access to them. The public features do not include placement of fill material for trails in wetlands. There are three, hand boat launches (for kayaks and canoes) proposed but no boat moorage facilities have been considered. There is a need for public education on the causes of habitat degradation and the benefits of restoring such habitats. Signage to inform the public will occur at suitable locations where budget allows. This comment is addressed in the section 4.13. A new paragraph under the section entitled Land and Shoreline Use. On Page 4 -17 a new paragraph will be added just after the second paragraph at the top of the page. The paragraph states: "It is important to provide public access and some park like amenities (such as trails, viewing platforms and hand boat launches) in a limited manner at a few of the restoration sites. This will only occur on lands that were purchased with recreation funds or the lands were purchased for the purpose of providing shoreline and public access prior to any suggestion of aquatic habitat restoration. The public features do not include the placement of fill material for trails in wetlands. Planning for public amenities will occur in a manner as to not jeopardize the objectives of the habitat restoration project." Comment: Biological Assessment. We would like to see a summary of the Biological Assessment in the final EIS (40 CFR 1502.25 (a)). By doing this, the EIS would demonstrate that the Endangered Species Act (ESA) procedures are being followed and that listed species, such as the chinook salmon and its habitats are being protected ". Response: There is information on the ESA currently in the Draft EIS. Sections 3.5.4, 3.6.3 and 3.7.1 discuss life histories. Sections 4.7.4, 4.8.3 and 4.9.2 discuss possible effects and Section 8 of the Restoration Plans outlines the procedure for addressing these issues. Federal coordination for ESA is described under section 7 of the act which identifies both US Fish and Wildlife Service (USFWS) and the National Marine Fisheries Service (NMFS) as the agencies with jurisdiction. The Corps has entered into Green/Duwamish River Basin Restoration Program 3 -4 Final Programmatic EIS the Water Resources Development Act. If the Ecosystem Restoration Study is to receive federal funding it will come through an appropriation in the Water and Energy Budget. The decision on if there will be funding and how much is left up to the U.S. Congress and the President. An estimate was conducted for the preferred alternative as part of the feasibility document with an estimated construction cost of $116 million dollars. None of the other alternatives have an associated cost estimate. Funding for construction of the projects is 65% federal and 35% local. Of the 35% local cost share, a portion can come from in -kind services as well as the value of the land the project is occurring on. Sources of local funding can come from a variety of non - federal sources such as Salmon Recovery Fund ALEA grants and from the local municipalities where the proposed restoration project is to be constructed. To address this comment a new section in the Restoration Plan has been created. On Page RP -23, section 4.4 Funding of the Restoration Plan, will state: "The Feasibility study cost estimate for the restoration plan is $116 million dollars. Of this projected construction cost amount, the federal share is 65% and the local match is 35 %. If the Ecosystem Restoration Study is to receive federal funding it will come through an appropriation in the Water and Energy Budget. The decision on funding is made by U.S. Congress and the President. A study such as this is usually authorized in the Water Resources Development Act.. Of the 35% local cost share, a portion may come from in -kind services as well as the value of the real estate the where the project is occurring. Sources of local funding can come from a variety of non - federal sources such as Salmon Recovery Fund ALEA grants and from the local municipalities where the proposed restoration project is to be constructed." Comment: Land and Shoreline Use. "Please clarify the statement (Page 4 -17) "Public access to natural resources could benefit from the individual restoration projects if the projects(s) include trails, viewpoints, and interpretive signs." The Corps has stated that some areas it would build a viewing platform or trails to some restoration sites, but added that a number of state /local ordinances could permit access to more sites. The final EIS needs to assess the impacts from access to sensitive habitats, such as an increase in the number of pets and people near a wetland area, and whether boaters would be allowed to drop anchor above delicate aquatic sites." Response: Concur. Clarification is needed. In the Draft Restoration Plan there are a few sites (such as Codiga Farms and Metzler) where restoration projects are planned and they do include some public facilities. As part of the proposal there are a few park like features such as trails, hand boat launch, viewing platforms and interpretive signage. These features are included for a few reasons: • They allow public to view and interact with nature access in a limited and composed manner. • They allow an opportunity to educate the public on the specific projects and the benefits of the restoration activities. Green/Duwamish River Basin Restoration Program 3 -3 Final Programmatic EIS RESPONSE TO LETTER #2 REGION 10, ENVIRONMENTAL PROTECTION AGENCY (letter dated August 10, 2000) Comment: Cumulative Impacts. "We recommend that the EIS discuss cumulative impacts of continuing the status quo through the no action alternative, and the relative benefits of the action alternative." Response: This comment has been addressed in the section 4.20.1. A new paragraph under the section entitled "Cumulative Impact of All Restoration Activities included in this Action" has been added. The following will be added to page 4 -23 as the last paragraph under section 4.20.1 "With specific regard to water quality, portions of the Green River, the Duwamish Estuary, and several tributaries of the Green River are recognized as water quality impaired per the State Department of Ecology Department's 303 (d) list due to fecal coliforms, metals, temperature, dissolved oxygen and hydrocarbons. Impacts from past activities, such as development, industry and water control projects have degraded the environment and continue to affect water quality and fish (Comment letter from Region 10 EPA dated 8/10/2000). In the long term, under the no action alternative there could be expected to be some improvement to this condition with the implementation of jurisdictional water quality plans as well as the State Department of Ecology's Total Maximum Daily Load study. Under both of the action specific alternatives discussed in this EIS, habitat improvements could also provide long term benefits for fecal coliforms, temperature and dissolved oxygen as habitat restoration projects are implemented. Many of the restoration projects include planting of native vegetation in a riparian buffer and some fencing on certain projects. Vegetation provides shade to the river and tributaries and filters out some of the contaminants prior to tier release to the receiving bodies. The scale of these benefits has not been quantified." Comment: Fundin . "We recommend that the EIS identify funding sources and the estimated cost of each alternative. The COE has said that the restoration will cost between $100 million and $150 million and that funding would come from the Water Resources Development Act and local matching grants. This project is 65% federally funded and 35% locally funded. One possible source of local funding identified in the EIS is the Regional Needs Assessment (RNA), a countywide effort to develop funding strategies for carrying out water resources projects. We recommend that the EIS include specific data on the possibilities of the project receiving matching funds. RNA process identified $50 million in design and construction in the Green/Duwamish Watershed." Response: Clarification is needed. Authorization and funding are accomplished by separate Congressional Actions. Specifically, a study such as this is usually authorized in Green/Duwamish River Basin Restoration Program 3 -2 Final Programmatic EIS In addition, we are pleased that the Corps has signed a Memorandum of Agreement (MOA) with the Washington State Office of Archaeology and Historic Preservation, the Advisory Council on Historic Preservation, the Muckelshoot and Suquamish tribes and local governments to comply with Section 106 of the National Historic Preservation Act. Activities under the MOA include identifying historic properties and evaluating their eligibility for the National Register. In addition, the agreement provides a protocol to protect cultural material or human remains of importance to the tribes. Please contact Val Varney (206) 553 -1901 if you have any questions.

Graves District Engineer Seattle District, Corps of Engineers P.O. Box 3755 Seattle, Washington 98124 -3755 Attention: Mr. Pat Cagney (FWS Reference: 1- 3 -01 -I -0906) Dear Colonel Graves: This letter responds to your August 31, 2000 transmittal letter and Programmatic Biological Assessment (PBA) for the Green/Duwamish Ecosystem Restoration Program which we received on September 5, 2000. We are able to provide partial concurrence. The PBA covers forty -nine restoration projects within the Green/Duwamish River Basin that the Corps of Engineers (Corps) is proposing for implementation over a ten year period. Fish and Wildlife Service (Service) and Corps staff have discussed on a number of occasions the need for more detailed project information to complete the Section 7 consultation. The Service proposed that the Corps meet annually with the Service, prior to the construction season, to review any refinements in project details that could have an impact on federally listed species, but especially the Coastal/Puget Sound bull trout. The Corps informed us in January 2001, that they were uncomfortable with the requirement for future reviews because of the uncertainties that could potentially affect project implementation. Instead, the Corps requested that the Service treat the PBA as a batch consultation. You further asked that we separate out any of the projects that we considered to be lacking in sufficient detail to complete the consultation, as well as projects for which we could not concur with the Corps' effect determination. For the purposes of this consultation, we are treating the forty -nine projects described in the PBA as a batch consultation. The Corps of Engineers has determined that the actions, as described in its PBA, are not likely to adversely affect the bald eagle (Haliaeetus leucocephalus), marbled murrelet (Brachyramphus marmoratus), northern spotted owl (Stria occidentalis caurina), gray wolf (Canis lupus), Canada lynx (Lynx canadensis) and Coastal/Puget Sound bull trout (Salvelinus confluentus). Based on the information provided in the PBA and the Corps' final feasibility report for the Green/Duwamish River Basin ecosystem restoration study, we concur with the Corps' determination of effects for the bald eagle, marbled murrelet, northern spotted owl, gray wolf, and Canada lynx. With regard to the Coastal/Puget Sound bull trout, we concur with the Corps' effect determination for forty -three of the forty -nine projects described in the PBA and listed in the attachment to this letter. These projects are covered under this consultation for a period of ten years. JD)ECCENED MAR 0 2001 USACE ATTACHMENT F REGULATOR' BRANCH We do not concur with the Corps' "not likely to adversely effect" determination for the bull trout • for the following six projects: (1) mainstem maintenance (Auburn to Elliott Bay); (2) middle Green River large woody debris placement; (3) middle Green River gravel replacement; (4) Flaming Geyser landslide control; (5) Newaukum Creek restoration; and (6) upper Green River gravel replacement. We recommend that the Corps consult individually on these projects. Although these six projects are expected to benefit bull trout in the long term, we believe they have the potential to adversely affect bull trout in the short term. These projects are larger and more complex than the others, involve significant in -water work, and have not been developed in enough detail at this time for us to conclude that the adverse impacts to bull trout would be insignificant. As project details become more refined, our concern for these projects and their potential impact to bull trout may lessen. In the absence of detailed project information, we need to be more cautious and therefore conclude that bull trout foraging could be adversely affected in the short term as a result of fine sediment releases during the modification of streambanks, the construction of engineered log jams, the addition of spawning gravels and the construction of other habitat improvements. Elevated levels of sediment can reduce the abundance of bull trout prey resources as well as make it more difficult for bull trout to locate their prey. This concludes informal consultation pursuant to 50 CFR 402.13. This project should be re- analyzed if new information reveals effects of the action that may affect listed species or critical habitat in a manner or to an extent not considered in this consultation; if the action is subsequently modified in a manner that causes an effect to the listed species or critical habitat that was not considered in this consultation; and /or, if a new species is listed or critical habitat is designated that may be affected by this project.

I have attached a copy of the Complete Application Checklist with the missing items identified. In addition, there are the following items: • It appears that the Title Report does not account for lots 44, 45, and 46 (Assessor's tax account number 017900 - 2469). These parcels are owned by James Codiga and are identified as being a part of the project on the site plan. If they are part of the project and privately owned, then property owner permission must be obtained to include them in the project and a Title Report submitted for them. • At the Pre - application meeting, there was a discussion about revising the parking to include only one lot. The site plan still shows two lots. Does the site plan reflect the correct layout of the project? Upon receipt of the identified items, the City will re- review them for completeness and will send you written notification of completeness or incompleteness within 14 days. The Shoreline Permit application will expire if we do not receive the additional information within ninety days of the date of this letter unless an extension is granted pursuant to Section 18.105.070(E). In addition, the Pre - application Checklist, provided after the meeting held on March 1, 2001, identified the need for a Conditional Use Permit for this project. That application has not been submitted as yet. It would make sense to consolidate all of the land use applications and determined to be complete so one public notice period can be used for all four of the applications. The Conditional Use Permit application should be submitted as soon as possible. If you have any questions please call me at 431 -3661. Enc.

James M. Rigsby Seattle District Corps of Engineers P.O. Box 3755 Seattle, WA 98124 -2255 Dear Colonel Rigsby: Ref: 98- 072 -COE The Environmental Protection Agency (EPA) has reviewed the draft Environmental Impact Statement (EIS) for the Green/Duwamish River Basin Restoration Program, CEQ No. 000208, according to our responsibilities under the National Environmental Policy Act and Section 309 of the Clear Air Act. The EIS proposes to improve the overall health of the ecosystem for fish and wildlife species by restoring the amount and quality of habitats. We are pleased that the Corps is undertaking such an ambitious project to restore and improve the Green /Duwamish River Basin, which has been affected by industrial use, flood control, grazing practices and residential development. We also appreciate your coordination with other agencies to ensure that the restoration activities complement each other. Of the three alternatives evaluated, the preferred alternative is a multi- species one which would reestablish a large area of aquatic environment and riparian corridors, and provide connections to existing productive habitats. This would benefit multiple fish and wildlife species found in riparian and riverine environments in the Green /Duwamish River Basin. Under this alternative, a total of 50 restoration projects has been identified and will be completed during al0 -year period. Based on our review, we have rated the draft EIS, LO -1 (Lack of Objections - Adequate). An explanation of the EPA rating system is enclosed for your review. We have commented below about the cumulative impacts analysis, the lack of specific information on project funding, and the level of public access allowed to the restoration sites, especially sensitive wetlands. Printed on Recycled Paper Cumulative Impacts Portions of the Green River, the Duwamish River Estuary, and several tributaries of the Green River are recognized as water quality impaired per the State Ecology Department's 303 (d) list due to fecal coliforms, metals, temperature, dissolved oxygen and hydrocarbons. Impacts from past activities, such as development, industry and water control projects have degraded the environment and continue to affect water quality and fish. We recommend that the EIS discuss the cumulative impacts of continuing the status quo through the no action alternative, and the relative benefits of each of the action alternatives. Funding We recommend that the EIS identify funding sources and the estimated cost of each alternative. The COE has said the restoration will cost between S100 million and $150 million and that funding would come from the Water Resources Development Act and local matching grants. This project is 65% federally funded and 35% locally funded. One possible source of local funding identified in the EIS is the Regional Needs Assessment (RNA), a county wide effort to develop funding strategies for carrying out water resource projects. We recommend that the EIS include specific data on the possibilities of the project receiving matching funds. RNA process identified $50 million in design and construction in the Green /Duwamish Watershed. Land and Shoreline Use Please clarify the statement (Page 4 -17) "Public access to natural resources could benefit from the individual restoration projects, if the projects (s) include trails, viewpoints, and interpretive signs." The Corps has stated that in some areas it would build a viewing platform or trails to some restoration sites, but added that a number of state /local ordinances could permit access to more sites. The final EIS needs to assess the impacts from access to. sensitive habitats, such as an increase in the number of pets and people near a wetland area, and whether boaters would be allowed to drop an anchor above delicate aquatic sites. Biological Assessment We would like to see a summary of the Biological Assessment in the final EIS (40 CFR 1502.25 (a) ). By doing this, the EIS would demonstrate that the Endangered Species Act (ESA) procedures are being followed and that listed species, such as the chinook salmon and its habitats are being protected. 2 Programmatic Biological Assessment for Green/Duwamish Ecosystem Restoration Program King County, Washington Species Under National Marine Fisheries Service Jurisdiction Prepared for: U.S Army Corps of Engineers Seattle District 4735 East Marginal Way South P.O. Box 3755 Seattle, Washington 98124 Prepared by: Jones & Stokes 2820 Northup Way, Suite 100 Bellevue, Washington 98004 -1419 • 425/822 -1077 June 2000 2.4 Program Activities The geographic focus will be at the watershed level, with the intent to manage restoration based on the total resource need rather than through individual projects. Examples of activities to be carried out under this program include: • Reducing barriers to fish passage — This activity will include reconnecting old channels by removing or relocating levees and other barriers. • Increasing habitat — This activity will include retaining or importing sediment and importing large woody debris (LWD) in the mainstem, side channels and in tributaries. • Increasing channel diversity — This activity will include improving the channel cross sections. Channel diversity will also be improved by the placement of LWD, gravel, and riparian plantings, which will lead to more diverse channel conditions. • Improving estuarine habitat — Habitat will be increased by creating deltaic habitat in freshwater tidal as well as saltwater areas: • Increasing streamside vegetation — Streamside vegetation will be increased by planting along tributaries, side channels and the mainstem. This program will be implemented through the Green/Duwamish River Ecosystem Restoration Program administered. jointly by the Corps. of Engineers and King County. Under this program, monitoring of restoration and restoration success will be accomplished from a watershed (ecosystem) approach, utilizing the monitoring protocol and GIS database program developed as a part of the ERS. 2.5 General Best Management Practices 1. All regulatory permits and official project authorizations must be secured before project implementation. All terms and conditions in these regulatory permits and other official project authorizations must be followed to eliminate or reduce adverse impacts to any endangered, threatened, or sensitive species or their critical habitats. 2. In -stream construction will occur only during approved in -water work windows based on the Washington Department of Fish and Wildlife Hydraulic Project Approval permit. 3. The use of heavy equipment that will result in excessive soil disturbances or compaction of soils will be minimized. 4. Use of heavy equipment in or adjacent to streambeth end streambanks will be minimized to reduce sedimentation rates, channel instability, and aquatic habitat impacts. If fording of equipment is absolutely necessary, vehicles and machinery will cross streams at right angles to the main channel whenever USACOUGRI!EN RIVERINMFS OWOS/OOe 6 Green/Duwamish Restoration Program Programmatic BA: Ecosystcm Restoration possible. Crossing sites will avoid sensitive fish habitat and areas susceptible to erosion, and they will be restored if necessary. 5. Excavation or transport equipment will be limited in capacity, but sufficiently sized to complete required restoration activities. 6. Streams, riparian zones, and wetlands will not be used as equipment staging or refueling areas. Equipment will be stored, serviced, and fueled at least 100 feet away from aquatic habitats or other sensitive areas. 7. Where possible, restoration activities involving excavation will take place in the dry season. Where new channels are excavated, the excavation will be isolated from surface waters then breached once work is completed. 8. Native vegetation will be planted on disturbed sites (including project site, disposal and staging areas, and access roads) when necessary to reduce soil erosion, establish cover, prevent invasive plant colonization, and provide shade. 9. Sedimentation and erosion controls (i.e., certified weed -free hay bales, silt fence, etc.) will be implemented on all project sites where restoration activities are implemented, materials or equipment are staged, or fill is placed to minimize the release of fines into the aquatic environment 10. Excavated materials removed during the completion of a restoration activity will be disposed of properly. 11. Boulder, rock, and LWD materials used for restoration projects will not be removed from any streams. 12. Inspection will be performed within one year following project completion to ensure that restoration activities implemented at individual project sites do not create unintended consequences to fish, wildlife, and plant species and their critical habitats. 13. Restoration activities will take place when minimal consequence to fish, wildlife and plant species occurs. 14. Any temporary access roads will be built to avoid impacts to fish, wildlife, wetlands, or other sensitive resources. Any temporary roads built will be obliterated and the area restored upon project completion. 15. All gravel /cobble material used for restoration activities will be screened to remove fine material prior to placement. 16. For all in -water restoration activities where sediment contamination is possible, a sediment quality analysis will be conducted for contaminants. Any restoration project found to be in an area that has unacceptable contaminant levels will be abandoned. For activities that create off - channel or new channel habitat, construction will occur in the dry therefore contaminated sediments will be removed and the site cleaned to meet acceptable sediment quality levels before the area is inundated. USACOGGREEN RJ VER/NMFS oarosrooa 7 Green/Duwamish Restoration Program Programmatic BA: Ecosystem Restoration 17. All sites where riparian plantings occur will be monitored for invasive exotic plant species. If exotic plant species are found they will be removed. 18. Site - specific surveys will be conducted within projects where there is a reason to believe the listed or threatened species may occur. For example, a survey will be conducted at the appropriate time of year to determine if listed or threatened species are present. 19.
