Rants, Mayor Department of Community Development Rick Beeler, Director January 15, 1993 Ralph H. Nichols Environmental Program Manager Washington State Department of Transportation District 1 15325 S.E. 30th Place Bellevue, WA 98007 -6538 Re:_ 1 -5 HOV Project XL -0011 Dear Mr. Nichols: This project crosses two important ravines in the City of Tukwila, which have streams that carry debris from I -5 during heavy rains. The debris plugs the City's drainage system, causing downstream flooding of private properties. Therefore, the project needs to contain mitigation measures for storm water detention and debris catching devices on the west side of 1 -5. Construction in Tukwila is controlled by a noise ordinance (TMC 8.22) and nuisance ordinance (TMC 8.28). The former - stipulates noise levels for this activity. However, the latter effectively, limits construction to between the hours of 7 am to 10 pm daily. Construction methodology needs to feature this constraint. Otherwise mitigation of noise impacts needs to be discussed prior to initiation of the project. If you have any questions, please call Ron Cameron (206 -433- 0179) regarding the drainage issue or Jack Pace (206 -431- 3686) concerning noise issues.

North Canyon is of more concern. A large portion of the east side I -5 fill section failed during the 1990 flood. It slid, taking trees and debris. The creek that passes under I -5 carries debris that has plugged our inlets and attributes to flooding of Southcenter Parkway businesses. Increasing flows to the Canyon should be mitigated with detention and debris catching devices if they can be designed and maintained on the inlet (west side) of I -5. Our comments to the January 5 SEPA Checklist should also explain Tukwila's noise ordinance requirements.

Name of proposed project, if applicable: Interstate 5, Fife To Tukwila, HOV & Truck Climbing Lane XL -0011 2. Name of proponent: Washington State Department of Transportation 3. Address and phone number of proponent and contact person: 15700 Dayton Avenue North, Seattle, Washington 98133 Contact person: Ben Brown Phone: 440 -4528 4. Date checklist prepared: December 31, 1992 5. Agency requesting checklist: Washington State Department of Transportation 6. Proposed timing or schedule (include phasing, if applicable): This project has been estimated to cost approximately $113 million. Due to the large cost and anticipated availability of funds, the project is planned to be constructed in 7 stages. The stages are as follows: Stage 1 Southbound, S. 188th Street to Tukwila Stage 2 Southbound, SR 516 to S. 188th St. Stage 3 Southbound, S. 320th to SR 516 Stage 4, Northbound, S. 272nd St. to S. 200th St. 1 Stage 5, Southbound, King Co. Line to S. 320th St. Northbound, King Co. Line to S. 336th St. Stage 6 Northbound, S. 200th St. to Tukwila Stage 7 Southbound, Fife to King Co. Line Northbound, Fife to King Co. Line Northbound, S. 336th St. to S. 272nd St. The Stage 1 project is currently planned to begin construction during the fall of 1993. It is estimated that the final stage will not be constructed for 7 to 10 years. 7. Are there any plans for future additions, expansions, or further activity related to or connected with this proposal? If yes, explain. The project being proposed in this document is an important element in the Puget Sound High Occupancy Vehicle (HOV) system. It would provide an integral link between the SR 5 system and the remaining I 405 segment proposed for completion in the mid to late 1990s. The project would expand HOV services southward to Tacoma and strengthen the HOV system. The project will improve the level -of- service for buses, van pools, and car pools and help transit services maintain their schedules. HOV lanes, metered ramps, park -and ride lots, and HOV bypass lanes are all components of the regional HOV system. The construction of HOV lanes through this section of SR 5 will provide much - needed support for the existing and planned park- and -ride lot system along this corridor. 8. List any environmental information you know about that has been, or will be prepared, directly related to this proposal. This Checklist is the only environmental documentation that will be circulated for this proposal. 9. Do you know whether applications are pending for governmental approvals of other proposals directly affecting the property covered by the proposal? If yes, explain. No. 10. List any government approvals or permits that will be needed for the proposal, if known. This project could require some or all of the following permits or approvals: Federal Nationwide Permit by U.S. Army Corps of Engineers Individual Permit by U.S. Army Corps of Engineers State NPDES Department of 401 Water Quality Certification Department of Temporary Water Quality Modification Department of Water Pollution Control Plan Department of Hydraulic Project Approval Department of Local Ecology Ecology Ecology Ecology Fisheries The "Growth Management Act" procedures (WAC 365 -195) required local agencies to establish comprehensive plans and regulations. This process is currently under way. At this time it is not possible to develop a comprehensive list of permit requirements. WSDOT will coordinate with the local agencies with jurisdiction and comply with all applicable ordinances. 11. Give brief, complete description of the project including (but not limited to) it's size, general design elements, and other factors that will give an accurate understanding of it's scope and nature. There are several questions in this checklist that ask you to describe certain aspects of the proposal. You do not need to repeat those answers on this page. This project proposes to improve a segment of SR -5 by constructing high occupancy vehicle (HOV) lanes from the vicinity of the Fife Interchange in Pierce County (MP 137.45) to the intersection of SR 5 and SR 405 at the Tukwila (Southcenter) Interchange (MP 154.46), within the City of Tukwila. The HOV lanes will be created by widening the existing roadway towards the median. In addition to the HOV lanes, the following items.of work are proposed: 24 mainline structures will be widened to accommodate the new roadway width. All the existing bridge rails will be replaced and upgraded to current standards. All on -ramps that do not currently have the capability will be widened for HOV bypass lanes. A truck climbing lane will be added to southbound SR 5 from the Tukwila Interchange to SR 516 (Kent /Des Moines Road). A Surveillance, Control, and Driver Information (SC &DI) system will be installed for the entire project corridor. Ramp metering will be added to all on- ramps. 3 An interim HOV project within the limits of this proposal was completed in 1991 and is currently operational. The interim lanes,• northbound from S. 272nd St. to S. 200th St. and southbound, Klickitat Dr. to SR 516 are currently operating with reduced lane and shoulder widths. This section will be upgraded as part of this project. 12. Location of the proposal. Give sufficient information for a person to understand the precise location of the proposed project, including a street address, if any, and section, township and range, if known. If the proposal would occur over a range of area, provide the range boundaries of the site(s). Provide a legal description, site plan, vicinity map, and topographic map, if reasonably available. This project would begin at the Fife Interchange at 54th Avenue East in Pierce County (MP 137.45) and extend northward to the intersection of SR 5 / SR 405 at the .Tukwila (Southcenter) Interchange (MP 154.46), a distance of approximately seventeen miles. See attached vicinity map. B. ENVIRONMENTAL ELEMENTS 1. Earth a. General description of the site: slopes, mountainous, other). This proposal traverses terrain ranging end of the project to rolling and hilly. b. What is the steepest slope on the slope) ? The steepest slopes within the project (50 percent). These slopes occur on roadside ditches and around bridge ends. (flat, rolling from flat at the hills, steep southernmost site (approximate percent of limits are approximately 2:1 the sideslopes of existing c. What general types of soils are found on the site (e.g., clay, sand, gravel, peat, muck)? If you know the classification of agricultural soils, specify them and note any prime farmland. The proposed project is located almost entirely within the existing right -of -way of SR -5, and ground surfaces subject to construction disturbance will be primarily areas previously disturbed during construction of the original SR -5. Much of this earth material is characterized as non - native fill material. d. Are there any indications of a history of unstable soils in the immediate vicinity? If so, describe. No. e. Describe the purpose, type, and approximate quantities of any filling or grading proposed. Indicate source of fill. The estimated total amount of excavation required for the project is estimated at 558,000 cubic yards. The estimated total amount of fill required is 571,000 cubic yards. f. Could erosion occur as a result of clearing, construction, or land use? If so, generally describe. Short -term construction related impacts to earth will consist of increased potential for erosion and sediment laden runoff. g. About what percent of the site would be covered with impervious surfaces after project construction (e.g., asphalt, buildings)? Approximately 60% of the project site will be covered by imperviously paved surfaces after construction, an increase of 20 %. h. Proposed measures to reduce or control erosion, or other impacts to the earth, if any: Erosion and sediment impacts will be minimized by adherence to the following general principles of erosion control and best management practices during construction. Additional and more specific measures may be made part of construction contracts. General guidelines for erosion and sediment control: The contractor will follow these guidelines while designing and constructing all erosion and sediment control measures. These measures will be part of the construction contracts, and continuous on -site monitoring will ensure the following principles are implemented during all construction activities. Implement erosion and sediment control measures prior to clearing or grading, throughout construction and after construction. Reduce the velocity of run -off from construction areas with proper control measures and minimize the volume of construction run -off flowing across bare soil areas by planned diversions. Provide temporary or permanent drainage facilities to control the run -off released from the construction area, with an emphasis on source isolation. 5 Clear only those areas which will be graded and stabilized during the current season. Exercise care to preserve the natural landscape; conduct all operations to prevent any unnecessary destruction, scarring, or defacing of the natural surroundings throughout the project area. Maintain all temporary erosion /sediment controls in a satisfactory condition until such time that clearing and /or construction is completed, permanent drainage facilities are operational, and there is no longer the potential for erosion. Adherence to these measures, and to any further measures required by state or local plans, permits or ordinances, is expected to prevent erosion and sedimentation impacts or reduce them to an insignificant level. 2. Air a. What types of emissions to the air would result from the proposal(e.g., dust, automobile, odors, industrial, wood smoke) during construction and when the project is completed? If any, generally describe and give approximate quantities, if known. The only emissions that would result from this proposal are dust and automobile emissions. WSDOT has completed an air quality study for this project titled "I- 5: Fife To Tukwila Interchange" dated October, 1992. The study found that in the 2010 design year, this project would represent an improvement over the 1990 existing condition. This project is in an air quality non - attainment area for carbon monoxide and ozone so it must conform with the State Implementation Plan (SIP) to meet the National Ambient Air Quality Standards. The current SIP for this area was approved by the EPA on February 28, 1983. This project is included in the Puget Sound Regional Council's (PSRC) Transportation Improvement Program (TIP) as amended. This project has been modeled and found to conform with the current SIP. As such, this project will not create any new violations nor contribute to the frequency or severity of any existing violations of the NAAQS for ozone. With its inclusion into the current conforming TIP, the project will not delay the timely attainment of the NAAQS for ozone and carbon monoxide. During construction, it is expected that there will be a temporary increase in dust, other particulate matter, and hydrocarbons. These are caused by increased truck and heavy machinery traffic, removal and /or placement of materials, and paving operations. The other construction impacts (odors) of the build alternative cannot be quantified. b. Are there any off -site sources of emissions or odor that may affect your proposal? If so, generally describe. No. c. Proposed measures to reduce or control emissions or other impacts to the air, if any: To mitigate the impacts of construction, contract specifications will be written so that those performing the construction work will be in compliance with all federal, state, and local air quality regulations. These regulations cover temporary highway construction impacts such as dust, smoke, and emissions. Burning will not be permitted. 3. Water a. Surface 1) Is there any surface water body on, or in, the immediate vicinity of the site (including year -round and seasonal streams, saltwater, lakes, ponds, wetlands)? If yes, describe type and provide names. If appropriate, state what stream or river it flows into. There are many small drainage basins within the project limits, all of which ultimately drains into Puget Sound through a system of tributaries. In the southern portion of this project, from approximately the vicinity of SR 18 to the south, the project is drained into Commencement Bay by the Hylebos Creek system. The remainder of this project, from the SR 18 vicinity, north to Tukwila, the surface water flow makes its way into the Duwamish /Green River system then to Puget Sound at Elliot Bay. 2) Will the project require work over, in, or adjacent to (within 200 feet) the described waters? If yes, please describe and attach available plans. Yes, the project will require bridge construction over Hylebos Creek. In addition lane construction will occur within 200 feet of the creek or one of its tributaries in several locations. 7 WSDOT has conducted a wetland inventory for this project. 17 wetland areas have been inventoried within the proximity of this project. The area that wetland impacts would occur as a result of this project begins at the Fife Interchange (54th Ave. E.) and continues towards S. 375th Street near the boundary line separating King and Pierce Counties. This area is in the final stage of construction for this project and is not scheduled for construction until after the year 2000. No detail information on impacts is available at this time. During the detail design of this Stage 7 of this project all impacts to wetlands will be avoided wherever practical. Where this cannot be achieved, impacts will be minimized to the greatest extent possible. Unavoidable impacts to wetlands will require compensatory mitigation. Wetland mitigation will be in accordance with all applicable State, Local and Federal regulations existing at the time of design and construction. 3) Estimate the amount of fill and dredge material that would be placed in or removed from surface waters or wetlands and indicate the area of the site that would be affected. Indicate the source of fill material. This information is not available at this time. 4) Will the proposal require surface water withdrawals or diversions? Give general description, purpose and approximate quantities, if known. No. 5) Does the proposal lie within a 100 year floodplain? If so, note location on the site plan. Yes, the proposal crosses the floodplain of Hylebos Creek south of the King / Pierce County Line. 6) Does the proposal involve any discharges of waste materials to surface waters? If so, describe the type of waste and anticipated volume of discharge. No. b. Ground 1) Will ground water be withdrawn, or will water be discharged to groundwater? Give general description, purpose and approximate quantities, if known. No. 2) Describe waste material that will be discharged into the ground from septic tanks or other sources, if any (e.g., domestic sewage; industrial, containing the following chemicals...; agricultural; etc.). Describe the general size of the system, the number of such systems, the number of houses served (if applicable) or the number of animals or humans the system(s) are expected to serve. None. c. Water Runoff (including storm water) 1) Describe the source of runoff (including storm water) and method of collection and disposal, if any (include quantities, if known). Where will this water flow? Will this water flow into other waters? If so, describe. An increased quantity of surface run -off will occur resulting from a net increase of impervious surface of approximately 60 acres. This run -off will run into the surface waters previously described by way of the highway drainage system. 2) Could waste material enter ground or surface water? If so, generally describe. No, not as a result of this project. d. Proposed measures to reduce or control surface, ground and runoff water impacts, if any: Mitigation of water quality impacts during construction will involve standard erosion and sedimentation control measures, as well as scheduling, revegetation, and other practices identified under the EARTH section. A Water Pollution Control Plan will be prepared and submitted to the Department of Ecology for approval. The contractor will be required to prepare an accidental spill cleanup plan and implement the plan if needed. The plan will include site specific conditions to be developed at the time of final design. In addition, the following general measures will be required during all construction activities. No construction activities are to occur in flowing water except as may be necessary to construct crossings or barriers. Material from construction work (i.e., soil, rock and other debris) shall not be discharged to surface water nor deposited where it could be eroded and carried to the stream by surface runoff or high stream flows. Disturbed soil areas and fill slopes shall be stabilized. There shall be no unnecessary damage to riparian vegetation. All work within the riparian zone will be coordinated with the State Departments of Fisheries or Wildlife. 9 There shall be no discharge of petroleum products, cement, cement washings or other construction materials to surface waters. Where working areas encroach upon live streams, barriers shall be constructed that are adequate to prevent the flow of turbid water into the stream. Compliance with the terms and conditions of the Hydraulic Project Approval, and Waste Discharge Requirements, if needed, will assure the protection of water quality. Adherence to the terms and conditions of these measures will prevent significant impacts to water quality of receiving waters during construction. Long -term surface water runoff impacts will be mitigated by measures including detention ponds and storm drainage facilities. These measures will be developed and designed in coordination with the Department of Ecology (DOE) and King and Pierce Counties. Measures will include following recommendations in the DOE's "Stormwater Management Manual for Puget Sound Basin ", the "King County Surface Water Design Manual" and consistent with the "Hylebos Creek Drainage Basin Management Plan ". These measures will prevent significant long -term water quality impacts. The proposed project does not include any withdrawals from or discharges to ground water. No impacts to ground water are expected. This project will be designed to be consistent with local agency regulations for detention and retention of highway runoff and with the DOE "Stormwater Management Manual for the Puget Sound Basin" for water quality. 4. Plants a. Types of vegetation found on the site. Due to the size of this project, the site covers a wide range of vegetation types. The predominate environment is highway median with grasses, shrubs and small trees. b. What kind and amount of vegetation will be removed or altered? Approximately 70 acres of vegetation would be disturbed by this project. Almost all of this vegetation loss is limited to the highway median consisting of shrubs and grasses with some trees. c. List threatened or endangered species known to be on or near the site. None. .. +nrcex_ +:u•.:ve:�rn.:�;71�ew: mars- ...MC.r•f....: d. Proposed landscaping, use of native plants, or other measures to preserve or enhance vegetation on the site, if any: To the greatest extent possible, vegetation removal during construction will be minimized. The disturbed areas will be regraded and revegetated to blend with the surrounding area in accordance to an approved landscape plan. 5. Animals a. Birds or animals which have been observed on or near the site or are known to be on or near the site. Hawk, eagle, heron, songbirds and small mammals (racoon, skunk, rodents). b. List any threatened or endangered species known to be on or near the site. None known. c. Is the site part of a migration route? If so, explain. No. d. Proposed measure to preserve or enhance wildlife, if any: This project will remove some habitat for the land animals but should not change the diversity of the animal population. It should have minor adverse impacts to land animals in the project vicinity. Overall this project should have an insignificant impact on wildlife in the area. Other than the revegetation and wetland mitigation described, no other wildlife preservation measures are proposed. 6. Energy and Natural Resources a. What kinds of energy (electric, natural gas, oil, wood stove or solar) will be used to meet the completed projects energy needs? Describe whether it will be used for heating, manufacturing, etc. None. b. Would the project affect the potential use of solar energy by adjacent properties? If so, generally describe. No. 11 c. What kinds of energy conservation features are included in the plans of this proposal? List other proposed measures to reduce or control energy impacts, if any. The completion of an HOV system, by encouraging the reduction of single occupancy vehicle use, and thereby moving more people in fewer vehicles, constitutes an energy conservation measure. 7. Environmental Health a. Are there any environmental health hazards, including exposure to toxic chemicals, risk of fire and explosion, spill, or hazardous waste, that could occur as a result of this proposal? If so, describe. Not as a result of this proposal. 1) Describe special emergency services that might be required. None. 2) Proposed measures to reduce or control environmental health hazards, if any: None required. b. Noise 1) What types of noise exist in the area which may affect your project (e.g., traffic, equipment, operation, other). None. 2) What types and levels of noise would be created by or associated with the project on a short term or long term basis (e.g., traffic, construction, operation, other)? Indicate what hours noise would come from the site. The only noise associated with this proposal is generated by traffic utilizing the facility or equipment noise during construction activities. Noise impacts already occur along this portion of SR 5 the noise levels resulting from completion of this proposal are not significant. WSDOT has conducted a noise analysis for this project and has determined that this proposal would increase noise levels by approximately 1 dBA over the existing noise levels. There will be temporary increases in noise levels from construction activities. During construction, persons living or working near the project will be exposed to noise generated from the contractor's equipment and operations. Large machinery and trucks delivering construction materials will be the major contributors. This type of noise tends to be intermittent and of a temporary nature. It is anticipated that construction activities will occur primarily during daylight hours. It may be necessary for the safety of the motoring public as well as construction workers to perform certain construction activities at night. 3. Proposed measures to reduce or control noise impacts, if any: Noise barriers were evaluated for each of the impacted residential study areas along the project. WSDOT is utilizing the Federal Highway Administrations noise abatement regulations for this project. These regulations require consideration of mitigation if it is feasible and reasonable to do so and to include those barriers for construction that are effective. A barrier is reasonable and feasible if it can physically and reasonably constructed without jeopardizing safety, health, maintenance, expansion, utilities, and environmental concerns. A noise barrier could be considered effective if substantial reductions in noise are possible and noise impacts could be reasonably eliminated. A 10 dBA noise reduction was considered substantial for conventional barriers. A cost criteria of $8,000 per residence was used for each residence that would have a noticeable improvement from barrier construction. The contractor will be required to adhere to the adopted Washington State Department of Ecology "Maximum Environmental Noise Levels" (WAC 173 -60), regulating construction noise close to residential areas between the hours of 10:00 p.m. and 7:00 a.m. In addition, the contractor will be required to adhere to all applicable local noise ordinances. 8. Land and Shoreline Use a. What is the current use of the site and adjacent properties? The site is currently used for vehicular transportation, adjacent properties are a mixture of residential, commercial and parks /open space. b. Has the site been used for agriculture? If so, describe. No. c. Describe any structures on the site. Not applicable to this project. d. Will any structure be demolished? If so, what? Not applicable to this project. e. What is the current zoning classification of the site? Not applicable. 13 f. What is the current comprehensive plan designation of the site? h Not applicable. g. If applicable, what is the current shoreline master program designation of the site? The project is not located within a shoreline zone. h. Has any part of the site been classified as an "environmentally sensitive" area? If so, specify. There are features within the project limits that have been designated sensitive by state or local agencies such as wetlands, streams, flood plains and steep slopes. i. Approximately how many people would reside or work in the completed project? None. j. Approximately how many people would the completed project displace? None. k. Proposed measures to avoid or reduce displacement impacts, if any: None required. 1. Proposed measures to ensure the proposal is compatible with existing and projected land uses and plans, if any: The proposed project has been and will continue to be coordinated with regional, county, and local plans and policies. The project site overlays several jurisdictions, including King County, Pierce County, the cities of Milton, Federal Way, Kent, Sea -Tac and city of Tukwila. Recommendations for improving transportation facilities, and transportation goals and policies are contained in plans for these areas. In general, the plans cited below support development of high occupancy vehicle lanes. The proposed project is consistent with the recommendations, goals, and policies contained in the following documents: King County - King County Transportation Plan, King County Comprehensive Plan, Puget Sound Regional Councils - Regional Transportation Plan, High Capacity Transit Work Program, and the Department of Ecology - State Implementation Plan. 9. Housing a. Approximately how many units would be provided, if any? Indicate whether high, middle, or low- income housing. None. b. Approximately how many units, if any, would be eliminated? Indicate whether high, middle, or low- income housing. None. c. Proposed measures to reduce or control housing impacts, if any: None required. 10. Aesthetics a. What is the tallest height of any proposed structure(s), not including antennas; what is the principal exterior building material(s) proposed? Not applicable. b. What views in the immediate vicinity would be altered or obstructed? None. c. Proposed measures to reduce or control aesthetic impacts, if any: None required. 11. Light and Glare a. What types of light or glare will the proposal produce? What time of day would it mainly occur? None. b. Could light or glare from the finished project be a safety hazard or interfere with views? No. c. What existing off -site sources of light or glare may affect your proposal? None. 15 .., d. Proposed measures to reduce or control light and glare impacts, if any: None required. 12. Recreation a. What designated and informal recreational opportunities are in the immediate vicinity? None. b. Would the proposed project displace any existing recreational uses? If so, describe. No. c. Proposed measures to reduce or control impacts on recreation, including recreation opportunities to be provided by the project, if any: None required. 13. Historic and Cultural Preservation a. Are there any places on or objects listed on. or proposed for, national, state, or local preservation registers known to be on or next to the site? If so, generally describe. No. b. Generally describe any landmarks or evidence of historic, archaeological, scientific, or cultural importance known to be on or next to the site. If so, generally describe. None. c. Proposed measures to reduce or control impacts, if any: None required. 14. Transportation a. Identify public streets and highways serving the site, and describe proposed access to the existing street system. Show on site plans, if any. Not applicable to this proposal. b. Is the site currently served by public transit? If not, what is the approximate distance to the nearest transit stop? This highway corridor is a major freeway corridor utilized by all public transit authorities to provide services to most all communites within the corridor. Within the project limits are several major and. minor Park and Ride or Park and Pool facilities. c. How many parking spaces would the completed project have? How many would the project eliminate? None. d. Will the proposal require any new roads or streets, or improvements to existing roads or streets, not including driveways? If so, generally describe (indicate whether public or private). No. e. Will the project use (or occur in the immediate vicinity of) water, rail, or air transportation? If so, generally describe. No. f.
