Thorpe to Opus Northwest. Opus Northwest however chose to withdraw their interest in development of the site. Prior to that, in August 2000, the City was prepared to issue a Determination of Significance (DS) and Scoping Notice based upon the proposal and the information we had received to date. The applicant requested an opportunity to revise the application either with additional information or revision. Although we met in September 2001 to discuss your ideas for further action, no further work/revisions have been received on the specific applications. You may be working on development of the site but the specific applications and subject proposal are not active. We therefore request that you write to us withdrawing your applications. As I mentioned in the June 5, 2001 letter to you, your work to date has resulted in significant research and information about the site, potential impacts associated with developing the site, and possible solutions. This information is not lost with a new application. The existing applications did not contain sufficient information and were incrementally amended and reviewed. My understanding from you is that a revised proposal would be substantially different. When you are ready to proceed with development of the site, a new application would be an opportunity to be comprehensive and move forward using relevant information already generated instead of revising or rescinding previous aspects of the project. I am sorry if this does not fit with your current schedule, I know your desire is the option of keeping the files open for an additional 6 months; however, we are unable to accommodate this request. If we do not hear from you by January 30, 2002, the City will proceed with the DS and Scoping. If I can be of any other assistance or if you have any questions, please call me at 206 431 -3651.

You asked for the details on the City's review of the proposed shoreline and land altering permit applications for the above project. As I mentioned, the City is considering a Declaration of Significance (DS.) A DS would require the preparation of Draft and Final Environmental Impact Statements (DEIS/FEIS) that evaluate project alternatives that would minimize adverse environmental impacts. In addition, the DEIS/FEIS process has a more extensive public comment opportunity. The applicant asked for a chance to respond to the outstanding issues of significant impact that staff raised in the draft environmental staff report. (See enclosure) The draft report should answer your questions regarding how the project is currently defined, what permits are required, and what standards apply to the geologic fossils on the site. The City has no time targets and we are currently waiting for the applicant to respond to the unmitigated items of significance that we have identified for the project. Should you have any questions, please fell free to call me at 206 431 -3651 or email me at mbradshaw @ci.tukwila.wa.us.

I live on Poverty Hill and I am concerned that all the homes on Poverty Hill will be endangered by the proposed plan. I also have concern that the proposal will destroy a area of land rich with culture, history, and paleontology. I am interested in knowing what specific requests the Community Development staff have been made of Wallace Enterprises up to this date and their responses to the requests. Have any changes been made by Wallace Enterprises to their original proposal? I would appreciate any other information on the whole process regarding this proposal and regarding Wallace Enterprises. Please inform me of the schedule for your department's handling of the original proposal and any target date by which the city will determine whether or not permits will be given to Wallace Enterprises. Thank you.

Mullet, Mayor Steve Lancaster, Director Project Description: The applicant proposes to grade the subject site, cutting and filling using blasting and mechanical removal and earth movement equipment so that the property is more useable in the future for light industrial development. The applicant has not presented any plans that show size or location for a building on the site. To achieve a more level site, the applicant proposes to remove approximately 221,326 cubic yards of rock/dirt from the site and to use the remaining rock/soils for preload and fill and grade. The site is a 10.96 acre undeveloped parcel bounded by the Duwamish River on the south, Puget Sound Power & Light Right of Way on the west, City of Seattle electric and water rights of way on the north and approximately 39 Av. S., if extended, on the east. Over half of the site is a rock outcrop of volcanic origin and variable rock types that are not neatly layered or areally arranged. There are also alluvial soils around the base of the rock outcrop that are weak in strength and prone to settlement. Surface elevations vary from 17.3 to 144.5 feet. (See Attachment A) The applicant proposes two methods of excavating the dirt and rock from the site. The upper layer (four to ten feet) of earth is proposed to be excavated by mechanical means (dozer blading and light ripping) The remaining layers (approximately eight feet to 102 feet) will be removed through a combination of mechanical extraction and blasting. Two different types of blasting are proposed: controlling or loosening blasts and production blasts. Up to 200 feet of the east (residential) property line controlled production blasting will occur. Between 200 and 100 feet of the east property line loosening/controlling blasting will be used. The last 100 feet along the east line will remain as is with a seventy -foot high rock slope with four benches each approximately 7.5 feet deep and fifteen feet high. •.

The site also includes Class 3 soils, where landslide potential is high and includes areas sloping between 20% and 40% and which are underlain by relatively impermeable soils or by bedrock and which also include all areas sloping more steeply than 40 %. CO vO. • w Within areas of potential geologic instability, the City requires a geotechnical analysis g ri and recommendation for the need for and the width of any buffers necessary to achieve u the goals of the Sensitive Areas Chapter. _ I— w z I— The State Department of Natural Resources defines a surface mine as "any area or areas z 0 i-' where extraction of minerals results in more than three acres of disturbed areas or surface w w. mine slopes greater than thirty feet high and steeper than 1 foot horizontal to 1 foot D o vertical. The definition of surface mining excludes excavations or grading used primarily p �` for on -site construction, on -site road maintenance, or on -site landfill construction. 01— ' Surface Mining Chapter (RCW 78.44.031) The rock outcrops, excluding the eastern 1" 111' comprise approximately 4.5 acres. DNR geologists say the application is likely to L O require a DNR reclamation permit especially in light of there being no application for z: actual construction on the site. 0 o ~. z According to Milbor -Pita, existing vertical rock faces show evidence of the site being previously quarried and that these vertical faces appear to be stable. The main rock types are andesite and breccia or what is referred to as Tukwila Formation. Smaller amounts of soft sedimentary rock outcrops occur on the flanks of the hill and alluvial soils occur on the flat areas surrounding the hill. Milbor -Pita reviewed previous site analysis conducted by Shannon and Wilson and Earth Consultants. Supplemental test pits were done, in addition to those conducted by Earth Consultants, and included two bores; which -were - used to evaluate: • the excavation requirements of the site, and • slope stability of the finished excavated perimeter. Milbor -Pita conclude that all the proposed excavation could be accomplished by mechanical means but such excavation will be very slow and costly and could create greater levels of noise and dust impacts on surrounding residents than blasting. They estimate that site excavation will be 1/3 light mechanical, 1/3 heavy mechanical and 1/3 blasting. Milbor -Pita states that excavated material will be of a size that is suitable for use as site fill. Any oversize rock will be separated by dozer and/or loader and stockpiled for removal to an off -site location. No dimensions or further discussion is given on the excavated material. -4- `°i DRAFT Of the two different types of blasting proposed, the loosening or controlled blasting is proposed in the area closest to the property edge that abuts residences. Within the 100 to 200 feet area west of the east property line, these loosening types of blasts are designed to heave the jointed rock mass rather than significantly break it. Heaving is accomplished by limiting the amount of explosive and matching the speed of the explosive to the sonic velocity of the rock mass. This requires closely spaced holes, which results in significantly higher costs per cubic yard of material. Production blasting will occur west of the 200 -foot setback from the east property line. The applicant describes a three -step excavation method. The benches will first be excavated with a large ripper dozer. Hard spots will then be attacked with a large hydraulic breaker. Any spots resistant to the breaker will be drilled and shot with blasts. The location will determine whether a production or controlling loosening blast will occur. In addition they state that blasting will average (emphasis added) one a day and will be limited to relatively small events, which in their experience significantly reduces complaints. The applicant proposes to create a new hill crest and rock face 100 feet west of the eastern boundary line. The plans submitted with the application are contradicted by the most recent drawing (Soil & Rock Excavation sketch Cross Section, no date) from the applicant's geotechnical consultant Milbor -Pita, that shows the 100 foot wide buffer from the eastern property line. The depth of the blast hole and subsequent excavation bench will be 15 feet deep by approximately 7.5 feet in distance resulting in a 75 foot high rock face. Shannon and Wilson, the peer reviewer, indicate that because a new rock face /slope is being created, its stability is uncertain. However because the proposed slope /rock face will be 100 feet from the east property line, it is unlikely that slope instability will result in disturbance off the property. Three types of impacts are possible from blasting: 1. Flyrock Milbor -Pita states that flyrock distances are dependent upon powder factors rather than hole diameters. They estimate flyrock potential of 100 feet and that this is somewhat irrelevant because they plan on controlling for any flyrock through proper stemming (packing of the drilled blast hole after the charge has been placed,) loading of the blast holes and through the use of blast mats. Flyrock impacts may also result when the sequence of blasts does not occur in the correct order. The applicant proposes to submit a Project Safety Plan that will provide a more detailed blast plan that controls for potential flyrock problems. -5- •z I I- ` '~ w rt JU • 0 U cow J H N LL.

Ground Vibrations There are two types of concerns associated with ground vibrations: structural damage and neighborhood complaints. The standard considered when evaluating potential impacts is maximum peak particle velocity (ppv, or intensity of the vibration) which is affected by the weight of explosives detonated within 8 millisecond time intervals during the blast. For background, the design of the blast loads creates ground vibrations that are measured on a seismometer, which can measure both the ppv and also the frequency of the ground vibration, measured in Hertz. The more closely spaced the wave created by the blast from peak to peak or the higher frequency of the vibration combined with a low ppv results in a lower impact to humans and structures. A high ppv combined with a wider spaced or lower frequency vibration results in a higher impact to humans and structures. The Office of Surface Mining (OSM) and the U.S. Bureau of Mines (USBM) have guidelines for maximum peak particle velocities that, if not exceeded, will limit the potential for structural damage. The agencies list a range of 0.2 to 2.0 inches per second of maximum velocities, which are tied to and dependent on either the predominant blast vibration frequency or the distance to the nearest structure. Milbor -Pita researched records that show the predominance of frequencies in the range of 10 to 100 Hertz when the ppv are less than 1.0 to 2.0 inches per second. Structural damage occurs at frequencies greater than 10 Hertz. The Milbor -Pita blast plan states that the maximum ppv achieved will be 1 inch per second. It is not clear if this is at all points around the property line. The Shannon and Wilson peer review cites a study showing complaints by persons located near a blast site. See below. The report does not mention the distance from the blast that the respondents are located but lists .20 as troublesome. Response Particle velocity (in.sec.) Noticeable .02 Troublesome .20 Severe .70 3. Air Blasts Air blast is an atmospheric pressure wave consisting of both high frequency and low frequency sound. The high frequency sound can be audible to people and the low frequency sound may be inaudible but experienced as concussion. According to Shannon and Wilson, the OSM limit air blasts to 128 decibels at any structure located within %z mile of the permit area. Milbor -Pita calculates that their production blasting will result in a maximum air blast of 120 decibels during production blasts and 100 — 105 decibels during controlled blasting. It is not clear at what distance this measurement would occur. -6- DRAFT 4. Fumes and Smoke See AIR below. In addition to the issues surrounding the blasting and mechanical removal of the rock are the issues of actual removal of the earth to other portions of the site and off site. The area of excavation on any given day will range from 1000 to 2000 square feet. The applicant has not clearly indicated if they are proposing an engineered fill and_preload. Shannon and Wilson state that the material excavated may not be suitable fill if the gradation of the rock is poor. That is, if the fill consists of a high percentage of boulder sized fragments with insufficient fines and smaller particles to fill between the voids of the larger rock fragments. Applicant states that they will monitor and be responsible for appropriate fill placement on site. Shannon & Wilson in a previous analysis recommended preloading the compressible soils on site, including clearing organics then placing and compacting the fill in controlled lifts. They recommended installation of settlement plates in 100 foot grids. The Erosion Control Plan and Report prepared by DOWL engineers states that work will start east and move west. This staging sequence requires greater description. Discussion is needed of how the site will be preloaded and filled in conjunction with the earth removal activities. Additional Analysis Needed/Potential Mitigation • Project Safety Plan including: ❖ fencing of unstable or sensitive slopes, extraction areas, etc. ❖ signage ❖ qualifications of blasting personnel • Revised Blast Plan that meets the more restrictive of the OSM and USBM guidelines /standards for surface mining activities.

Lesser amounts of carbon monoxide and oxides of nitrogen gases can also be produced. In addition to the gases and water vapor, blasting also produces smoke that is a combination of water vapor and products of detonation and combustion. Excessive exposure to smoke can result in severe headaches. Smoke and gas fumes can be reduced by properly selecting blasting agents and explosives, by limiting the quantity of powder in the hole and by adopting appropriate blasting methods and procedures. Milbor -Pita asserts that design of the limited individual blasts to small events minimizes the negative effects of smoke and fumes. Milbor -Pita states that in addition to the proper design of the blasts themselves, there are operational efforts that will limit air impacts. A Project Safety Plan would not permit personnel access to the blast site until smoke has cleared and the registered blaster in charge has inspected the site. There are a number of weather conditions that can positively effect the impacts from the project. On windy and or rainy days smoke and fumes dissipate very rapidly. Working during the wet season and/or wetting the excavation site will control dust. The applicant states that haul roads on the site will be wetted and the blast hole drilling rig will be fitted with a dust suppression kit. Enviroanalysis, a subconsultant on the peer review team, states that dust from construction is generally not a serious health hazard though it can present a nuisance to some people. The Puget Sound Clean Air Agency does not issue permits for the type of activity proposed because the applicant affirm that no rock crushers are to be used. The Agency does have control measures for fugitive dust that would be appropriate for the types of activity proposed and are included below. -8- •z ti._W • J V, • V Q.

The wetland edge at its z �' closest is within 35 feet of the northern boundary. A 50 foot buffer and a 15 foot z o commercial setback are required between the wetland boundary and any work on the w w, subject site. . o . 'O co;. m jI The proposed erosion control plan and the grading plan do not show the required 15 foot setback from the 50 foot buffer. The wetland is located within a closed depression of approximately 55 acres. Six acres of the 10 acre subject site drains to the north into the closed depression. This storm water runoff area is approximately 10 % of the contributory area of the closed depression. During and following the proposed activities, the applicant proposes to route all site drainage through a sedimentation pond, through a biofiltration and detention swale to the Duwamish river through an existing City outfall and drainage system located in S. 115 St. Erosion/Sedimentation Control Notes state that facilities shall be inspected and maintained a minimum of once a month or within 48 hours following a storm event. Potential Mitigation • DOWL Engineers suggests that a storm event be defined as any 24 -hour storm event of 0.75 inches or greater. • Maintenance and inspection records Plants The Existing Tree Study, (R.W. Thorpe; August 11, 1999) identifies trees types and their calipers within the sloped areas classified as sensitive areas per the Tukwila Zoning Code, Sensitive Areas Chapter (TMC 18.45.020E.) The area to be cleared does not exactly match the Milbor -Pita proposed finished grades. The number of trees to be removed and replanted is significant. The replacement plan shows the majority of the -9- DRAFT 206 trees to be planted in the public right of way adjacent to the river. While replanting the riverbank is a good thing. Planting trees in this location of the public right of way is not acceptable to the City. The spacing and density of trees proposed would create a complete visual and physical barrier to the river from S. 115 Street. The proposed project will need to be revised to show how and if the applicant can plant the required number of trees outside of the right of way and above the ordinary high water mark of the river. Animals The applicant notes that typical urban wildlife, such as Bald Eagles, raccoons, possums, etc, may use the site. The Duwamish/Green River abuts property and is habitat for threatened Chinook salmon and possibly includes the presence of Bull Trout, which has been spotted in the river. The project will connect to an existing outfall to the Duwamish and the impacts are unknown. Environmental Health Noise Short term The applicant has characterized the proposal as a construction project to clear and grade the site for future development. As such, all noise generated on the site during daytime hours will be exempt from the City's noise standards. The Peer Review consultant raised the question of whether the proposal should be characterized as a construction operation or a quarry operation because of the length of time involved in clearing the site. If the proposal was classified as a quarry rather than a construction site, the consultant thinks that the proposal could exceed maximum permissible sound levels allowed by City ordinance. The equipment on site and the truck traffic moving the excavated material off site will be the primary noise source from the project. Excavation activities are proposed during daylight hours and only from 7:30 to 5:00 p.m. The area affected most adversely by noise will be the residential neighborhood south of the Duwamish River. This area receives a significant amount of noise due to the surrounding freeways, railroad, airport and firing range. The peer review consultant took a short term noise sample from the crest of the hill along the project's east property line and found the maximum noise level to be 76.5 dB (A.) and the minimum to be 53.6 dB(A) and the average to be 64.1 dB(A.) The sound measurements along S. 115 St. on the south side of the property were lower 64.6 dB(A) and 46.7 dB(A) with an average of 51.5. dB(A.) The City's standard for residential areas that receive noise from industrial areas is 60 dB(A.) This standard may be increased from 5dBA to 15 dBA depending on the type and duration of sound being generated. 1 „w' 6 - U 00. O. u, w w =: J wo. gQ` = d:. �w r z� O. z g. tu w pi o O- 1- w w'.

The City's Comprehensive Plan has a goal on Noise Abatement Goal 7.2 Residential neighborhoods protected from undue noise impacts, in order to ensure for all residents the continued use, enjoyment and value of their homes, public facilities and recreation and the outdoors. Soil Contamination A 1988 Shannon and Wilson Soil Report for Elmer. White had six borings and 30 samples taken. Five had a noticeable petroleum odor with the odor becoming less strong with depth at the one boring. The lateral extent of the contamination was not explored. In its analysis for a previous project proposal, S& W recommended chemical testing and further evaluation. Because of the amount of mechanical equipment on site there is the potential for further spills and contamination. Are remedies for this prudent or required prior to filling the site?

In the Tukwila Comprehensive Plan, the site is designated as Manufacturing Industrial Center Light. The site is also zoned Manufacturing Industrial Center Light. The parcel is approximately 10.97 acres in size and is bisected on the south side by S. 115 Street. (A portion of the parcel, approximately 20 feet deep by 590 feet long exists between S. 115 St. and the river. Puget Sound Energy Right of Way on the west is being used for vehicle storage. The City of Seattle electric and water rights of way border on the north contains utility lines and pipes. Beyond the 200 foot wide right of way to the north is a City of Seattle Police Department firing range. To the west of the 100 foot wide Puget Sound Energy right of way is a commercial light industrial building. Single family homes in a Low Density Residential District abut the parcel on the east and continue south of the site along S. 115 St. and 42 Av. S. The applicant proposes razing a portion of Poverty Hill to create a relatively flat site that will be suitable for an office /warehouse building, which is a typical use of the MIC/L zone. D Housing Not applicable. Aesthetics No structure is proposed at this time. Views in the area will change with the removal of this valley visual landmark. Light /Glare The applicant has not proposed any lighting of the site during the grading project, Recreation The Interurban/Green River Trail is across the river from the site. A neighborhood park, Duwamish Park is, located at 42 Av. S., approximately 2 blocks from the site. Historic /Cultural Preservation Documents exist that describe the importance of this site for Native American Indian culture as well as for paleontology research. For Native American Indians, more specifically Duwamish mythology, this outcrop along with several other nearby knolls in the Duwamish Valley, are incorporated into a story about climate and weather - the story of the battle between the North and South winds. The myth recounts the battle between northwind and Stormwind ... explains the origin of the seasons and also provides the basis for rituals designed to alter the weather. Duwamish women carried baskets of water to wash the face of a rocky knoll at Riverton, called Grandmother of Stormwind, so she could exercise her power to bring rain and cause floods, and young boys swung specially made bull - •roarers around their heads mimicking the sound made by Stormwind when he drove cold northwind from the land. These same myths tell of the collapse of a great ice dam on the Duwamish River near Allentown. (Bruerge, 1980.) The applicant contacted the Department of Natural Resources to verify the importance of the site for paleontological purposes. Two documents were referenced by the applicant as verification that the site is not significant geologically to the state: • Geologic Time, Rocks, Fossils, and Mineral in Washington, Department of Natural Resources, Division of Mines and Geology (no date) • Fossils of Washington, Vaughn E. Livington, Jr. (1972) Dave Norman, Geologist with the Department of Natural Resources, stated in a conversation with City of Tukwila staff that Washington State does not require the -12- Z Z CC • J U� UO' N 0': U W' W =; J H wO =• a �w 'z �F ZI- 111 uj UO. co O- 0 I— ww LI O: u i Z; U O~ z DRAFT protection of marine invertebrate and plant fossils, which are relatively abundant, and which are found on Tukwila Hill in the Tukwila Formation. He said that if a large vertebrate fossil is found then work should stop and DNR contacted. He also suggested that a paleontologist at the Burke Museum be contacted, as DNR does not have a paleontologist on staff. • z Elizabeth Nesbitt, a research paleontologist with the Burke Museum wrote a paper in ct 2. 1995 regarding the Tukwila fossils. She explains that the fossils are 40 million -year -old 6 clams, snails, coral and fish. Within the Puget Sound Area she states that only two • v O ..(00 exposures of these fossils are still accessible. The other site has been studied and does co w: not have the value of the subject site. co u_ Ms. Nesbitt states that very little research has been conducted on these deposits and that O; there are similar fossils preserved in southwestern WA but this is the farthest north that g animal fossils as old as 40 million years have been found. These fossils and rocks w indicate that 40 million years ago this area was the western coast of the continent. And I w that the climate was very different — it was warm and subtropical.

Policy 1.2.1 The Sensitive Areas Chapter of the Tukwila Zoning Code establishes standards for "Areas of Important Geological or Archaeological Evidence." It states: 1. "Development on a legal lot of record determined to have historic or prehistoric geological or archeological evidence shall be prohibited until that evidence has been studied or researched for any valuable information about our history. Removal or salvage of the evidence shall be done in accordance with RCW 27.53..." (Revised Code of Washington Archaeological Sites and Resources Chapter) 2. Once geologic or archaeological evidence or articles have been studied or researched, or the importance of the site is declared to be marginal or not of use to the scientific community, development shall be allowed on the site." -13- :•S.Y. ••v.:'gi�C�Fri a'.t,'H7� K _+`*"sue. DRAFT If salvage is the only option available and because of limited storage.space, Ms. Nesbitt says that only a small amount of materials could be salvaged. She roughly estimated that if salvage could occur at the location and elevation where she knows there are significant fossils, then it will take one day with four people. Transportation Access to the site is via East Marginal Way S. to S. 115 Street, a collector arterial. Truck and other vehicle traffic will result in 168 one direction trips per day. During each of the am and p.m. peaks, there will be 26 one way trips. Tandem dump trucks hauling approximately 900 cubic yards of excavated material will account for 71% of the daily trips. The City Engineer considers this amount and the type of traffic to be significant for S. 115 Street and that a geotech study /analysis is needed to determine if the street can handle the heavy loads. Additional Analysis Needed/Potential Mitigation • Geotechnical analysis of street conditions on S. 115 Street • Traffic control measures such as flaggers or warning signs, as determined by the City Engineer, during all hours of operation. • Applicant responsibility for improving street to accommodate proposed traffic, cleaning of debris and repair of street damage. Public Services Police and fire protection services are the only anticipated services needed for this proposal. The applicant does not plan on storing explosives on site because they are available locally from suppliers. The Fire Department requests a plan outlining the transportation of the explosives.

In addition, the applicant has not completed all of the research necessary to successfully conduct and accurately described the proposed project. There appears to be modification of the proposal since its initial submittal, which resulted due to the subsequent drafting of a preliminary blast plan. There is also the potential for significant noise impacts on a residential neighborhood and the loss of a portion of a significant paleontological and cultural site. Earth Milbor -Pita submitted additional details regarding blasting procedures that were not included in the peer review. A peer review of these details and more specific blast and fill details is needed to evaluate the applicant's proposal. The Erosion Control Plan does not match the most recent drawing submitted by the applicant's geotechnical consultant. Nor does the grading plan adequately describe the site preparation for a future light industrial building. The applicant's proposal is not clear on how excavated material will be placed on the site. They state that most of the initial excavated rock will be used as fill, as part of the site preparation work. However, an engineered fill is needed to support any future building that may be constructed on the site on top of fill material. Milbor -Pita states that all rock will meet required gradation for fill. The City needs to know how gradation will be tested and how fill will be placed on the site. Shannon and Wilson raise the issue of slope instability developing after excavation and that the owner should take remedial measures to prevent instability from impacting adjacent properties. How will instability be detected following the excavation project? A discussion what types of remedial measures might be needed is required of the applicant. Water . The applicant's wetlands and civil engineering consultants, Wetland Resources and DOWL, have concluded that the diversion of all site drainage to the Duwamish River will not adversely impact the wetlands natural functions and value. The Erosion Control and Grading Plans do not show the minimum required setbacks from the wetland; therefore revised plans need to be submitted. Trees The applicant has not demonstrated how they can meet the revegetation requirement of the Tree Regulations Chapter of the Zoning Code. Environmental Health The applicant has not fully discussed the long term noise impacts from the proposal. The City's peer review indicated that impacts to the Duwamish neighborhood could be .. DRAFT significant because the hill that is proposed for removal currently acts as a noise barrier for the airport, railway tracks and firing range. The peer review recommends a more detailed analysis to evaluate the project's impacts on noise levels and potential mitigation. The applicant has not investigated the chemical contamination of the site and needs to discuss the evidence of contamination and remedies. Land/Shoreline Uses The proposed use of the site for an office /industrial use is in keeping with the Comprehensive Plan designation and zoning. Historic and Cultural The site, which is a portion of what is called Poverty Hill, makes up an important feature in Duwamish mythology. It is also important for paleontological purposes. Its destruction will remove a physical reference point for a culture. Salvage of fossils, which is required per City code, will allow the paleontological evidence to be studied and preserved albeit without it relevant geology.

Here are two of the chief reasons we believe that this site should be preserved rather than dynamited and developed: • According to Native American legend, this site is the spot where the world was created • It is one of only two undeveloped sites containing 42- million - year -old fossils (shells, sharks teeth) that prove that this area was once tropical before global warming and a sudden cooling period killed the shellfish; the Poverty Hill site is the northern -most site ever found that contains these fossils (see the April 1998 Washington Geology article by Elizabeth A. Nesbitt, Ph.D) Some facts: • The parcel is 10.97 acres. • According to the County Assessor, the size of the site is 10.97 acres; the owner is Wallace Enterprises; the property address is 11215 E. Marginal Wy S.; and the assessed value as of 12 -13 -99 is $836,200. • An application to develop this 10.97 -acre site is currently pending. • The southwestern corner of the parcel (100 feet by 100 feet square) is a separate tax parcel owned by William Looney; this parcel is currently for sale for approximately $90,000. As a neighborhood, we want to preserve this site for future generations. We understand that there are several sites along the Duwamish River that are significant to Native American culture. Because this is one of the only sites still undeveloped, we want to be sure to take a united step forward now, before it's too late. We are interested in working with the city to do whatever is necessary to acquire this site, including developing a public /private coalition or partnership to establish the vision for this park and to raise the funds to make the acquisitions.

We recently gathered more than 70 signatures protesting the 4a -., application to permit blasting and removing the two hills on this parcel. _ d I- w. From our research, we have learned that according to Indian legend, this site is sacred -- it's z �; believed to be the spot where the world was created. This is documented in Chapter 2, p. 16 to 1- O 21, of Salvatore Trento's book, Field Guide To Mysterious Places of the Pacific Coast. We're w w' awaiting additional documentation of this information from David Beurge, a former historian for n o" the Duwamish Tribe. ,0o N` 0 I- Also, Elizabeth Nesbitt, Curator of the Geology Division at the University of Washington's = v'; Burke Museum of Natural History and Culture, has visited this site many times, and has u... i: documented the existence of 42- million- year -old fossils that prove that this land was once z tropical (including shark's teeth and shells). Ms. Nesbitt was instrumental in arranging the 0 (0 filming of a "Bill Nye, The Science Guy" segment on this site. The segment included 0 1 schoolchildren from a Tukwila middleschool class. In the segment, Nesbitt describes the value of Z hands -on experience in teaching children more about their environment. We fully appreciate the rights of private landowners. However, we have many strong concerns about the effects of blasting, the removal of these hills and consequences for Poverty Hill and the surrounding area, the cultural and scientific loss, and the many additional negative implications that would result from the development of this parcel. We're aware that the city is scrutinizing the application very closely and has already requested a list of more detailed information and facts from the applicant. City Planner Carol Lumb has been extremely helpful in explaining these details to us. Here's some of the facts we know about this parcel: ... Wallace Enterprises bought this parcel on May 2, 1988 for $800,000. It's currently assessed at $836,200. The taxes are $13,552.77 per year. ... The parcel is zoned light industrial. Our neighborhood protested an earlier attempt (prior to 1988) to develop this parcel. ... The parcel has been up for sale several times in the past several years. The bottom line is that we're very much interested in preserving this parcel for future generations. We've had very preliminary initial conversations with the Duwamish Tribe, the Page: 1 Document Name: Assessor KING COUNTY DEPARTMENT OF ASSESSMENTS PAI11075 -51 AS29 RECEIVABLES 12/13/99 ACCOUNT NUMBER: 102304-9057-0 PROPERTY ADDRESS: 11215 E MARGINAL WY S TAXPAYER NAME: WALLACE ENTERPRISES QTR: NW SECT: 10 TWN: 23 RNG: 4 FOLIO: C20225 -A- SUBAREA: 420 -000 SHORT LEGAL DESCRIPTION: LOT BLOCK PLAT: 0 BILL OMIT N S LEVY OMIT TAXABLE VALUE APPRAISED VALUE TOTAL APPR IMP YEAR YEAR C C CODE CODE LAND IMPS TAX BILLED TAX PAID LAND IMPS VALUE INCREASE 2001 2418 836,200 836,200 836,200 "2000 2418 836,200 836,200 836,200 1999. 2418 836,200 13,552.77 13,552.77 836,200 836,200 1998 2418 836,200 11,896.50 11,896.50 .1997 2418 836,200 12,760.63 12,760.63 BILL LEVY TAXABLE VALUE F PTRL DRN DRAINAGE DRAINAGE DATE DUE YEAR RECEIVABLE TYPE CODE LAND IMPS TAX BILLED TAX PAID ACRES DST BENEFIT ACRES CERTIFIED DATE 1999 N WEED 9420 1.84 1.84 NEXT ACCOUNT: 102304 9057 0 * * END OF RECEIVABLES * * JUMP CODE: ( 0.4) ENTER-PFI--PF2--PF3--PF4--PF5--PF6--PF7--PF8--PF9--PF10-PF11-PF12-PF13-PF14-PF15-PF16-PF17-PF18-PF19-PF20-PF21-PF22-PF23----PF24-- HELP•END MENU CHAR RIOT LEOL LRFT ROHT APPR PF -HELP MENU+ mate: 12/13/99 Time: 02:10:20 PM Page: 1 Document Name: Assessor NO BUILDINGS FOUND FOR THIS ACCOUNT.

I am very concerned about the potential damage to my house's foundation and ceilings and about the damage to our environment. I know that Tukwila has made efforts to increase the environmental health of the city. Losing these two hills will increase the noise impact of the firing range, aircraft noise, and railway noise for many of my neighbors to the west and south. The site itself is an archeological site that has been used by many UW students for many years. It is one of the undeveloped sites still present in Tukwila and has historical value. I propose that Federal and State funding be sought to purchase the property and turn it into an archeological park. I believe that UW would probably be willing to enter into an agreement to assist with site identification, etc. As a resident of Poverty Hill I already tolerate high noise impacts from Boeing Field, the BNSF Burlington Northern loading yard, and air pollution from both. Please do not allow more noise and air pollution to damage my neighborhood. We don't need more trucks running through the neighborhood. Thank you.

Desjardin @PSS. Boeing.com> Resent -From: clumb @ci.tukwila.wa.us Carol, I feel that I must send another message on top of the letter that I wrote. The increased traffic alone would be a tremendous burden on roads that were not designed for the traffic they're currently handling. In fact S.115th has a weight limit and cannot have any heavy trucks on it (except fire trucks), so how in the world would they get equipment in there and haul away the debris? To get to the site from the East, you have to travel on 42nd. Ave. South, which turns into S. 115 St. These are basically residential streets, they can't handle the extra traffic. With only 2 lanes, if there were much more traffic, it would impede the fire trucks. Then considering the extra pollution that would be added to the air and river (from storm drains, runoff, etc.) it's just unthinkable. The new pollution from businesses, cars, trucks, and if there's no hill to block the wind, possibly 1 -5 pollution and jet fuel fumes from King County Airport. (I currently work at Renton Field, and I wouldn't need the extra jet fuel fumes at home.) So, add these issues to the others on my letter and this should be a resounding no!

W. Thorpe & Assoc. for Jim White NOV 1 81999 DEVE OPivii ENT We are opposed to the proposal of blasting or otherwise demolishing the 2 hills that has been put before the city. For the humans in the immediate vicinity, the 2 hills are our only defense from the noise from the firing range, the airport, the railroads, and I5. Removing the hills, trees, and other vegetation would make already high noise levels in our community unbearable. Having to deal with the noise, vibrations, dirt, dust and great potential for damage to our home is equally unbearable. As a new homeowner in the area we are particularly upset as we paid a very high price for a little piece of this neighborhood because of the rural aspects it has. Blasting could very well cause geological damage to the riverbanks and the land of Poverty Hill putting our neighbor's homes in jeopardy. For the wild life in the immediate vicinity, the loss of habitat and the food would be devastating. The blasting and demolishing of the 2 hills could very well have a permanent, adverse impact on the fish and other wildlife of the Duwamish River. From what we understand, this area has some archeological and historical significance. We certainly hope that a genuine and substantial environmental impact study will be mandated before a decision is reached. We are normally a proponent of the right of privacy and self - determination for landowners. In this case, we must speak out because we see a complete disregard of the broad and irreversible ramifications this proposal would have on the local humans, animals and ecological systems that are already here. *z . 40.

Z` 0 Z November 13, 1999 Carol Lumb Department of Community Development City of Tukwila 6300 Southcenter Blvd, #100 Tukwila WA 98168 re: Removing 2 hills next to Poverty Hill proposal by R. W. Thorpe & Assoc. for Jim White We have reviewed the plans to level the 2 hills on this property. We are opposed to such a drastic action. We.believe that blasting or otherwise demolishing the 2 hills that have been in place for such a long time would cause irreparable harm to the surrounding community. Here's why: c1 ,..i.1 '7 '099 l 1899 Blasting, demolition,, or heavy construction activities are bound to cause damage to our homes, our foundations, our walls. It wasn't that long ago that residents in a class action suit settled with the quarry for blasting damages to their homes. Also, neighbors rememberthat when the BECU building was constructed a couple miles south of here several years ago, we felt the vibrations in our homes — all because of the sandy, water- logged soil we live on which readily transmits and intensifies vibration's. Blasting, demolition, or heavy construction activities may likely have an effect on the geological stability of Poverty Hill and the homes thereon — we would hate to witness loss of homes or lives due to mudslides or other geological problems that could be traced back to the date that the blasting or other demolition activities began: Blasting, demolition, or heavy construction activities may likely cause damage to the very fragile Duwamish riverbank — may disrupt bank stability or accelerate bank erosion = and our riverfront homes are already perilously close to the edge of the riverbank. Blasting, demolition, or heavy construction activities may likely cause damage to the Duwamish river in terms of any salmon eggs, fish, or other wildlife in the river itself The heavy and constant truck traffic necessary to remove the hills would likely cause : the same damage kind of damage as mentioned above. • The noise from blasting, demolition, sustained truck traffic, and any construction activities would add to an already- impossibly high noise level in our communities The 2 hills are our only defense from the noise from the firing range, the airport, the railroads, and I5. Removing the hills, trees, and other vegetation would make noise levels in our community unbearable. The dust, grime, and other particulate matter caused by blasting, demolition, or heavy construction activities would add to an already high level of air. pollution The 2 hills are meccas for wildlife, including birds — such as osprey and eagles — who use this territory as a training ground and source of food We believe that the city is attempting to do its best to preserve trees and wildlife habitat — this flies in the face of such significant efforts; also, we understand that President Clinton is also interested in preserving as much greenbelt as possible; the City of Tukwila currently has a tree ordinance — the City of Seattle is now in the process of drafting a tree ordinance to preserve habitat before it's destroyed forever There are archaeologically significant fossils and other items (neighbors tell me of shark teeth they have found!) in those hills; the UW has done archaeological research there; fossils are 40 million years old. The Duwamish Indian tribe may have an interest in what happens to this property See the attached article for the description of this property as the center of the world! As landowners ourselves, we know that private property owners have aright to do with their property as they wish. But in this case, in these circumstances, with so much at stake, we believe that this proposal is not in the best interests of the community — now and into the future -- or even the landowners themselves. We would urge them to consider carefully the:ramifications_of .their intentions, and to speak with our community. When communications are open, great things happen! For example, one idea would be to convert this parcel to a parkland or greenbelt. We're proud to be residents of this neighborhood, and count our blessings daily. This is truly a.wonderful place to live. Our only desire is to keep it that way, for all of us, for our . children and • s, and for the wild creatures who share this riverside paradise. orgina and.

I live across the river from the site, which is at South 115th approximately 170 feet east of East Marginal Way South, in Tukwila. The destruction of the hill would seriously increase the noise pollution to the area south, from the firing range. The area is already inundated by a great deal of noise. King County International Airport, Burlington Northern and other businesses in the area also create substantial noise. We currently Y don't hear noise from Interstate 5, but with removal of the hill, I'm afraid we would hear that noise too. There is an osprey nest on S.112th. The osprey pair return every year and raise a family. They use the hill and the surrounding land as hunting ground and training ground for the young osprey. During the spring and summer, I've seen bald eagles hunting there also. Red tail hawks nest there. The area seems to be a breeding, nesting and training area for wildlife, in other words, a wildlife habitat. The hill material, which is Tpt; Tukwila formation (late Eocene); sedimentary rock according to my generalized geologic map, is not extremely stable. I have some concerns about the removal process. If, during the removal process, there are vibrations, other property on the hill could be seriously jeopardized by jointing and fractures. This would in turn, probably translate into damaged foundations, a change in drainage patterns, which can be very devastating if you suddenly have an underground stream emptying into your basement or across your property. Taking into account a 1/4 mile radius of the area there are foundations, road beds, riverbanks, bridges and other structures that exist on silt and could be seriously damaged by any process that causes vibration. In essence, the hill tends to break up the sound waves, dampens the reverberations and vibrations and helps to block some of the visual impacts imposed on our residential neighborhood by the commercial ventures in the area. The hill has always acted as a barrier for us. The hill is also a life supporting resource for the remaining wildlife living in the area. I look forward with great regret to the day the hill could possibly be destroyed. Cathie DesJardin 3826 S. 116 St. Tukwila, WA 98168 w. J U. • 00. co 0 CO III, • wi: J w O: LL a; a.

Tax Lot No. 102304 - 9057), have been found to be complete for the purpose of beginning substantive review) Pursuant to our conversation on September 16, 1999, the application is modified to reflect that "Alternate 2 Concept" and "Alternate 1 Concept" are actually Phase 1 and a subsequent Phase 2 further grading (respectively). Alternative Concept 1 (Phase 2) is the proposed action, as it is the most extensive action. Substantive review will begin and will very likely result in additional information requests to demonstrate consistency with City development standards. Information requests will include, but not be limited to actual site surveys which are stamped by a professional surveyor, information on excavation characteristics in order to determine if this is a permitted use, and traffic generation. ' Several requirements for the shoreline permit such as surveyed site topography, surveyed banks and bank • cross- sections, have been waived for the purpose of a "completeness" determination in order to allow beginning the public comment period. However, they will be required to complete substantive review. 6300 Southcenter Boulevard, Suite #100 • Tukwila, Washington 98188 • (206) 431-3670 • Fax (206) 431-3665 • Z • < Z • w o: g, • :UOY. .,cno ill s: J I-• N LL J • =a.

A notice of application form will be laminated by the Department of Community Development. You will be notified when this is ready for you to pick up. After the form has been installed, please drop off a signed Affidavit of Posting to show proof that the notice board and proper notices have been installed. You will be responsible for removing the notice board from the site once your application has been approved and finalized, and when all public comment periods have terminated. The Alternative 1 Concept Rough Grading Plan should be used as the "Site Plan" on the board. This may be printed on the board or attached as a laminated plan.

SHORELINES DESIGN POUCIES All projects in the Shoreline Zone must be consistent with Tukwila's Comprehensive Plan and Shoreline., Master. Program policies (or King County's Shoreline Master Program if project located north of the 42nd Avenue bridge). In addition, all structures requiring a building permit (except single family development of 4 or fewer Tots) located in the Shoreline Zone must undergo design review with the Tukwila Board of Architectural Review (BAR). The BAR's decision is based on design guidelines contained in the Zoning Code (TMC 18.60.050) and the Tukwila Comprehensive Plan (see DESIGN REVIEW APPLICATION). The SHORELINE MASTER PROGRAM POLICIES and Comprehensive Plan's SHORELINE DESIGN POLICIES are summarized below. Note that more than one category may apply. In some • cases, the goal for the use or area is noted to provide context for the design policies. NOTE: a) If your project requires a building permit you must meet additional criteria in DESIGN REVIEW APPLICATION. b) If your project requires a variance, you must meet additional criteria in VARIANCE PERMIT APPLICATION. c) If your project requires a conditional use permit, you must meet additional . criteria in CONDITIONAL USE PERMIT APPLICATION. TUKWILA SHORELINE MASTER PROGRAM POLICIES (King County shoreline policies follow) A. ECONOMIC DEVELOPMENT ELEMENT 1. Commercial/industrial development along the shorelines should not favor outside interests at the expense of the local population. 2. Locate commerciaVdevelopment in areas with low potential for recreation or other public uses. 3. Preference should be given to commerciaVindustrial development that will provide an opportunity for a substantial number of people to enjoy the shoreline.

SHORELINE USE ELEMENT In order for the site to be used economically, the proposed grading needs to be conducted. N o significant biological impact on either the land or water environment is anticipated as a result of the proposal. Views onto the subject property will be substantially altered as the 110' rock outcropping is proposed to be substantially graded. 6. CONSERVATION ELEMENT The proposed grading will change the view onto the subject property. Future development o n the property will include landscaping, as per Code requirements. There will not be an increase in storm water run -off as result of the grading. In addition, the proposal does not involve the discharge of waste material to surface waters. 7. HISTORICAL/ CULTURAL ELEMENT No historically or culturally significant sites have been identified on the property. However, should any evidence of historic, archeological, or culturally important sites be unearthed all construction activities would be placed on hold and the appropriate state or local agencies would be contacted. Tukwila Comprehensive Plan Shoreline Design Policies 1. The development minimizes impacts on wildlife & significant vegetation, sandbars, wetlands, watercourses, and other important habitat features are maintained through the proper location, construction, management of shoreline uses (5.9.1). The proposed grading will occur on the portion of property to the north of South 115th Street, and will not disturb any significant wildlife habitat or vegetation. The riverbank and immediate shoreline environment will not be impacted by this proposal. White .Tukwila "Rock Pile" 1 Shoreline Substantial Development Permit 8/9/99 2. The development protects riverbank vegetation and, where feasible, restores degraded riverbanks (5.9.2). There will be no negative impacts on the riverbank as the proposed grading will occur only in the uplands portion of the property, across South 115th Street from the river. 4. Streets, flood control, surface water drainage and sewer system projects, clearing/grading activities and landscaping are designed, located and managed in a manner that minimizes water pollution, provides erosion control, and protects water quality (5.10.1) There will not be an increase in storm water run -off as result of the grading. The proposal does not involve the discharge of waste material to surface waters. Standard erosion control measures will be taken during the grading. 7. The development is designed and located to minimize impacts to habitat, vegetation, access, recreation, historical resources and flood control (5.3.2). The proposed grading will not have a significant impact in . relation to these issues. Projects within Manufacturing/ Industrial Center (MIC) 1. The development maintains or enhances existing visual quality; provides trees and landscaping as buffers; and provides amenities that enhance employees' enjoyment of the river (5.5.2). The proposal is for grading only. As a part of the eventual development of the property as an industrial site landscaping will be provided, as per code. r 2. The non -water dependent development provides for multiple shoreline uses or provides mitigation for loss of multiple use opportunities (5.3.9). Grading will only occur on the uplands side of South 115th Street and not impact the potential for multiple shoreline uses. 3. The development emphasizes restoration of riverbank vegetation (11.1.8). No riverbank vegetation restoration is currently planned as a part of the grading plan as riverbank vegetation will not be impacted. 4. Development on the east side of the river improves employee access (11.1.8). Grading will only occur on the uplands side of South 115th Street, therefore riverfront access will not be impeded. 5. Development supports the Duwamish River becoming a natural feature amenity in the MIC (11.1.7). The proposed grading will not be detrimental to this goal. White - Tukwila "Rock Pile" 2 Shoreline Substantial Development Permit 8/9/99 King County Shoreline Master Program SHORELINE USE ELEMENT Objective 2. Shoreline land and water uses should satisfy the economic, social and physical needs of the regional population, but should not exceed the physical carrying capacity of the shoreline areas. The grading of the site will help satisfy the economic needs of the region and the property owner by increasing the development potential of the site. This would provide for a future industrial development, and not threaten the river since the portion of the site to be graded is on the uplands side of South 115th Street. ECONOMIC DEVELOPMENT ELEMENT Objective 1: Rather than being dispersed, shoreline industry and commerce should be encouraged to locate in present publicly identified and developed areas to the extent of the land and water carrying capacity. Policy 1: To relieve stress on less developed areas, new industry and commerce should be encouraged to locate in intensive use areas which can be upgraded and redeveloped. This property is in the center of the urban area and is part of the MIC zone. Additionally, the adjacent properties are currently fully developed with industrial and residential uses. As such, the proposed grading will further the intent of this policy. Objective 3: Shoreline economic development which may have a significant or substantial detrimental effect on either land or water environment should be constructed and operated in a manner to minimize these effects. Policy 2: During excavation and other erosion and sediment activities, appropriate sediment control procedutesand devices should be used to protect the watercourse. Standard erosion control measures will be taken during grading. These will include measures outlined in Washington State Department of Ecology publications. It i s anticipated that specific measures will include the use of silt fences, straw bale dams, and timing construction to coincide with dry weather as much as practicable. PUBLIC ACCESS ELEMENT Objective 5: Public access should be provided in new shoreline development. As the proposed grading will occur only on the uplands side of South 115th Street public access will be unaffected along the riverbank. CONSERVATION ELEMENT Objective 4: Scenic, aesthetic and ecological qualities of natural and developed shorelines should be recognized and preserved as valuable resources. These qualities of the Duwamish River shoreline area would not be disturbed by the proposed grading on the uplands side of South 115th Street.

The faunal diversity is considerably greater than previously re- ported. Eighty -four taxa have now been recognized (Table 1), almost triple the number recorded by McWilliams (1971). The majority of the fossils are mollusks, but the assemblage also in- cludes four corals, an echinoid, polychaete worm tubes, brachiopods, crab claws, shark teeth, and benthic foraminifera. Plant fossils from the Tukwila Formation include both ever- green broadleaf and mixed deciduous forest species. The mol- lusks are strikingly similar to those from the well -known Cowlitz Formation of southwestern Washington. Biostra- tigraphic correlation indicates that the western outcrops of the Tukwila Formation are late middle Eocene in age, 39 to 41.5 m.y. More detailed investigations of the stratigraphic position of the outcrops may be needed. The Tukwila Formation is part of the Puget Group, which also comprises the coal - bearing rocks of the Black Diamond - Carbonado area (Fig. 1). Sediments of the Puget Group were deposited over approximately 10 million years in rivers and their distributaries within a broad Mississippi River -type del- taic system (Buckovic, 1979; Burnham, 1990). Rivers flowed from what is now Idaho westward across a pre- Cascade conti- nental plain to a fluctuating coastline situated about where In- terstate Highway I -5 is today. These areas of terrestrial and ma- rine sedimentary accumulation were part of the western Wash- ington forearc during middle Eocene time (Nesbitt and others, 1994). In the early and middle Eocene, Pacific Northwest subduction- related volcanism was active in a belt that extended from the Republic graben in northeastern Washington, through the Challis area of central Idaho, and southwest to Clarno in northeastern Oregon. During the late middle Eocene, about 40 million years ago, the center of arc volcanism shifted to the Table 1.

GEOLOGY The Tukwila Formation was the name given by Waldron (1962) to andesitic volcanic and interbedded sedimentary rocks exposed within the city boundary of Tukwila, near the Duwamish River (Fig. 1). Vine (1969) expanded the definition of the unit to include a more complete section in the Taylor Mountain —Tiger Mountain area, northeast of Hobart, eastern King County. In this region, the Tukwila Formation consists of 2,100 m of volcanic and volcaniclastic rocks that are entirely contained within the coal- bearing sediments of the Puget Group. The base of the Puget Group is not exposed there, and the measured thickness for the group is more than 2,700 m (Buckovic, 1979). Rocks of the Tukwila Formation consist of andesitic tuff, massive sandstones, carbonaceous shales and coal strata, and volcanic flows and sills (Vine, 1969). The Tuk- wila Formation interfingers with the marginal and nonmarine sedimentary rocks of the underlying Tiger Mountain Forma- tion and overlying Renton Formation, also part of the Puget Group (Fig. 2). Farther south, in the Green River area and the Black Diamond coal mining region, the Puget Group cannot be subdivided (Waldron, 1962). Here, coal is interbedded with sandstone and mudstone in a depositional environment charac- Figure 1. The Tukwila Formation outcrops in the Tukwila area have been studied for more than a quarter century. Biostratigraphic equiva- lents are known from localities to the south.

Very rare freshwater clams, Batissa newberryi, have been found in these sedimen- tary layers (Michael Conaboy, Pacific Coast Coal Company, oral commun., 1997). Quaternary sediments obscure any possible continuity be- tween outcrops of Tukwila Formation in western King County and those in the Tiger Mountain area of eastern King County. The strata have been correlated on the basis of their lithological characteristics. Tukwila Formation rocks are characterized by andesite lava flows, breccias and lapilli tuff, and sediments de- rived from these volcanic deposits: siltstone and coarse- and medium - grained andesitic sandstone, andesite breccias, and weathered andesitic cobble conglomerates (Vine, 1962, 1969; McWilliams, 1 971). Marine fossils have been found only in the western exposures close to the Duwamish River (Fig. 1). Out- crops of the Tukwila Formation in this area are capped by an- desitic breccias. Immediately below the breccias and above the marine sandstones is a very thin and geographically restricted, clay -rich lakebed deposit that contains fossil plant debris. The marine fauna occurs in discrete, densely fossiliferous strata that are exposed on the flank of an east - trending anticline (McWilliams, 1971). Six of these faunal intervals occur in one stratigraphic section that measures approximately 40 m thick, and rare scattered shells are found between each of these inter- vals. Most of the fossils are preserved with the shell material intact, but in some of the strata the fossils are molds and casts. Most exposures of the Tukwila Formation do not contain body fossils but are highly bioturbated. STRATIGRAPHY AND AGE The Puget Group consists of a thick sequence of deltaic sedi- ments, with a few shallow marine incursions, and interfinger- ing andesitic volcanic rocks at its northern and southern extents (Buckovic, 1979) (Fig. 2). The volcanic rocks of the Tukwila Formation have been correlated with those of the Northcraft Formation in Lewis and Skamania Counties, southwestern Washington (Buckovic, 1979). However, there is no informa- :r. ,. T Figure 3. John Henry No. 1 coal mine, Pit No. 2, in January 1998.

The coalbed at this location is approximately 10 ft thick and contains a few bony partings along with the coal. for coal exported to South Korea for steam generation. This percentage is nearly the same as in 1996 (24 percent), but the actual sales to that market dropped by 67 percent. The remain- ing sales were for electrical generation (2 percent of total sales) and to supply public and private institutions and residential customers (1 percent of total sales) for space heating. In 1997, PCCC mined coal from two pits. At Pit No. 1, it mined coal from the Franklin Nos. 7, 8, 9, 10, and 810 coalbeds (Fig. 2). Coal in Pit No. 2 was mined from the Franklin No. 12 coalbed (Fig. 3). The Franklin coalbeds are stratigraphically near the base of the undivided Eocene Puget Group in nonma- rine deltaic sedimentary rocks. In 1997, PCCC mined coalbeds in Pit No. I along the north- west limb of the anticlinal structure to near the maximum min- ing depth for the mine (Fig. 2). PCCC also continues to mine a clay bed between the Franklin Nos. 9 and 10 coalbeds. The clay is blended with high alumina clay for manufacturing portland cement. • BOOK REVIEW: Environmental Interpretation — A Practical Guide for People with Big Ideas and Small Budgets by Sam H. Ham, 1992. Available from North American Press, 350 Indiana St., Suite 350,Golden, CO 80401 -5093; 303 - 277 -1623. Paperback, 456 p., S37.50 + $4.00 shipping. Also available in Spanish. Sam Ham is a professor in the Department of Forestry at the University of Idaho in Moscow. His main academic inter- ests are resource recreation and tourism. His book is nothing less than a comprehensive, if not exhaustive, guide to environ- mental interpretation and communication that draws upon his 20 years of experience in the field. Why should environmental interpretation be so important to the people of Washington State? For one thing, visitors and ecotourism dollars from around the world are rushing to the alluring natural splendor of the Pacific Northwest in ever - increasing numbers. Conferences that feature field trips to such natural laboratories as Mount St. Helens and revered natural wonders such as Mount Rainier, Puget Sound, the Olympic Mountains, and the Columbia Gorge have become an enormous draw. Along with the growth in visitation of natural resources comes an increasing need to satisfy the educational cravings of visitors and at -the same time to foster a respect for natural areas. This "eco- rush" is taking place in a dynamic academic landscape in which information about the geologic and natural environment has grown almost exponentially during the past several decades. As a result, there is an increasing need to clearly convey technical and appreciative information about natural resources to people of diverse backgrounds. Environmental Interpretation is an excellent, easy to read treatment of the theoretical and practical aspects of communi- cating with a wide variety of audiences. Mr. Ham's forte is blending a captivating thematic approach to interpretation with content that is technically sound as well as suited to the audi- ence and the setting, be it a classroom, a scenic overlook, a trail hike, or an interpretive sign or display. The book presents about 20 case studies and contains more than 200 illustrations, several appendices (glossary, types of display and exhibit mod- els, lettering aids, list of organizations), and numerous refer- ences. Two pages alone, "There are many ways to make techni- cal information more entertaining ", contain plenty of inspira- tion for jaded interpreters. Chapter titles include: 1 What is interpretation? 1 Practicing thematic interpretation 1 How to prepare and present a talk 1 Tips on using visual aids 1 How to present a guided tour or walk 1 Guidelines for other conducted activities (demonstrations, theater, roving interpretation, angry visitors, etc.) 1 How to prepare and plan inexpensive exhibits 1 How to develop inexpensive self - guided tours Environmental Interpretation is an excellent resource for both the experienced scientist and the novice interpreter. Teachers, park rangers, land and program managers, museum staffs, nature and hiking groups, and others will all find parts of this book that are "essential reading ". by Patrick T. Pringle M.Y.

Within the Macrocaliista-dom- inated beds are small shells (15 mm in length) of juvenile Glycymeris, Tellina, Spisula, Microcallista, Acanthocardia, Venericardia, and Pitar. Boreholes left by sponges that grew on mollusk shells (or epibionts) are very rare and found only on shell fragments. Such deposits indicate that high energy currents have displaced the normally infaunal ani- mals and concentrated them on the sediment surface, where they died be- fore being able to re- establish life posi- tions. Rapid reburial prevented surface abrasion or the growth of epibionts. High- spired gastropod fossils gen- erally have their canals and apices bro- ken off and have the long axis in a northwest orientation, parallel to the bedding plane. In addition, current - oriented patches of elongate scaphopod and serpulid worm tubes lie among the dam shells (P1. 1, fig. 2). This align- ment indicates that erosion and deposi- tional currents were strong enough to move and re- orient the shells. The thin, densely packed, fossiliferous strata consist of shells that have accumulated from storm - generated bottom currents; the resulting bedforms are called tempestites. These are interspersed within many meters of sandy sediment con- taining few body fossils and tubes that are preserved as in- place or autochthonous fauna. Tempestites are characterized by restricted continuity of single beds that are densely fossilif- erous, by hummocky cross stratification, and by amalgamation (Einsele and Seilacher, 1991). Such an environment of deposi- tion would result in numerous local unconformities and re- working of previously deposited sediment. As a result, little can be concluded about the actual rate of deposition. Most of the exposed sedimentary rocks of the Tukwila For- mation in western King County are highly bioturbated, and very little of the original stratification is evident, except for the tempestites. In those deposits with well - preserved shells, there is very little abrasion or evidence of reworking. The shells in the tempestites indicate rapid erosion of infaunal animals from the inner neritic sea floor; these are mixed with those trans- ported in from farther offshore and those that were attached to rocks in the intertidal zone. This mix of shells was then depos- ited and covered immediately by current - oriented deposition. -t:-.)•111' *.. t*:....•.,:v.,,A:tek.44i;,,..1...4.44:5:::,4:11‘..f.t(lie.-; , „ ,N2 i .,,:, 0..i, 7j , .c.

PALEOECOLOGY AND DEPOSITIONAL ENVIRONMENT Defining the paleoecology of molluscan faunas depends on comparisons with the ecological parameters for living popula- tions of the same phylogenetic families. Molluscan systematics is based on those hard and soft parts involved in feeding; there- fore inferred trophic comparisons are a reliable way to recon- struct paleocommunities. In addition, the wide ranges of shell shapes and ornamentation are fundamental designs that allow prediction of life habits. However, it has also been demon- strated that, in a few families, depth ranges and temperature tolerance changed during the Tertiary, so cautious interpreta- tion is warranted. In the final analysis of paleoecology, the in- fnrmatinn fns Per]+ • , ... . i ____._.__........... paleo- assemblage under study. A good example is the three species of the marine cone shells (Conus) in the Eocene Cowlitz fauna; all are found in the deeper water assemblage (Nesbitt, 1995), but the vast majority of cones now inhabit shallow subtidal and reef environments. These fossil cone spe- cies are unusually high- spired. High- spired cones are rare in modern faunas, and this shell design is considered primitive. The very high species diversity of the Tukwila fauna (84 genera, of which 70 are mollusks) and the fact that almost all the genera are characteristic of warm, shallow seas indicate that, at this time, western Washington had a tropical to sub- tropical climate. The most notable fossils for making this de- termination are members of the following gastropod families: Strombidae (conches), Cypraeidae (cowries), Conidae (cones), Ficidae (fig shells), and Cymatidae (tritons). (See Pl. 1, figs. 3, 4, 6, 13.) Most of the molluscan genera in the late middle Eo- cene Washington faunas are the same genera that now live in southern California, Baja California, and Gulf Coast faunas. Living species of molluscan families that occur in the Tukwila Formation today inhabit shallow marine water in sandy to silt substrate environments, in the tropics of eastern and western Pacific; many of them are confined to coral reef communities. The prominent genera of tropical gastropods that are found in Eocene deposits of southern California and the Gulf Coast, Athleta, Distorsio, Campanile, and Velates, are absent from the middle Eocene of Washington. This and the fact that very few of the gastropods from the Tukwila and Cowlitz Formations are large or highly ornamented indicate that these species may have been on the outer edge of their biogeographic range. Four corals, Astroaeapora, Turbinolia, Balanophylla, and Discorrochus (Durham, 1942), have been found in the Tukwila shell beds, and all specimens are small. Corallum diameters range from 5 to 10 mm, and heights from 10 to 20 mm. Corals are very sensitive to thermal gradients. Living reef (herma- typic) corals are confined to areas where water temperatures re- main higher than 20 °C in winter.

Washington Geology, vol. 26, no. I , April 1998 17 typic coral now living in the tropics of the Pacific Ocean, and Turbinolia is restricted to the Caribbean Sea. On the other hand, Balanophylla is a solitary, nonsymbiotic coral that lives to a depth of 10 m along the California and Oregon coast in much cooler water. Comparing the Tukwila fauna to the paleoassemblages of the contemporaneous Cowlitz Formation in southwestern Washington reveals that the majority of species are compo- nents of the Turritella—Tivelina Assemblage (Nesbitt, 1995) that lived in a shallow (inner neritic). normal marine environ- ment with a sandy to silty sand substrate. This assemblage is characterized by infaunal filter - feeding mollusks: the numeri- cally dominant, very shallowly infaunal gastropod Turritella, the shallow infaunal pelecypods Venericardia, Pitar (Pl. I , fig. 7), Acanthocardis, and Glycymeris, and deep infaunal pelecy- pods Tivelina, Tellina (Pl. 1, fig. 8), and Macrocallista (Pl. 1, fig. 1). A high diversity of rare gastropods is also a characteris- tic of the Turritella—Tivelina Assemblage. In the Tukwila de- posits, the small pelecypods dominate numerically and volu- metrically, the most prominent being Macrocallista. The Tukwila fauna also includes a mixed assemblage of mollusks from other environments of deposition. The most nu- merous of these belong in a group confined to intertidal, hard - ground paleoenvironments and the group restricted to fine - grained substrates in deeper water (outer neritic to upper ba- thyal). Hard - ground components include limpet -like Patel - loida, Crepidula, and Calyprraea (Pl. 1, fig. 9), mussels, and the corals. Characteristic deeper water (outer neritic) compo- nents are rare, but they include gastropods from the families Turridae, Conidae, and Mitridae, opisthobranch gastropod genera Scaphander (Pl. 1, fig. 10) and Cylichnella, as well as the taxodont pelecypod Nuculana and the brachiopod Tere- bratulina. In addition, leaves, stems and seeds, and uncommon brackish -water mollusks (Acutostrea, Corbula, and Eulima) are also present in the shell deposits. The abundant calcareous tube - shaped shells in this fauna have previously been identified as the scaphopod Dentalitim. However, three different shell morphologies are present. The least common taxon is a scaphopod, but it is the genus Laevi- dentalium (Pl. 1, fig. 11). Scaphopod mollusks are identified on radulae and foot morphology, and it is very difficult to put fossil forms into meaningful taxa. Fossil Laevidentalium is identified by a thick - shelled, smooth tube that has horizontal growth lines but no longitudinal ribbing. The other two cal- careous tubes are those of annelid worms belonging to the mor- phological family Serpulidae. These narrower tubes are at- tached to the substratum for much of their length and are inhab- ited by filter- feeding polychaete worms. One of the Tukwila tubes is similar to the fossil genus Protula (Pl. 1, fig. 2), which has a long, narrow, tapering tube that is circular in cross section and exhibits a smooth, thin wall. The other tube is the posterior uncoiled extension of the helically coiled Rotalaria (Pl. 1, fig. 12), which has a thicker wall than Protula and distinct longitu- dinal ribs. The only taxa recorded to date that are present in the Tuk- wila Formation but absent in the Cowlitz Formation are the cowry Sulcocypraea (Pl. 1, fig. 13), a small fissurellid -like lim- pet, Laevidentalium, and the two polychaete tubes. Two genera of cephalopods, Nautilus and Cimomia, have been reported from the Cowlitz Formation but not from the Tukwila fauna. CONCLUSIONS Single event deposition, such as tempestites, erases any paleo- assemblage data, and very little can be ascertained of the inver- tebrate paleoecology. Only by comparing the Tukwila species with those from the paleoassemblages recorded in the Cowlitz Formation can inferences be made. The species lists are practi- cally identical, and evidence of mixed living assemblages indi- cates that the Cowlitz shallow marine environment extended to at least the central Washington Tukwila coast, almost 100 mi to the north. These may have been part of the same deltaic system, as indicated by Buckovic (1 979), or they may be the termina- tions of different rivers. However, Tukwila Formation sedi- ments indicate proximity of andesitic source rocks. Because there is no evidence of tectonic translation for Eocene sedimen- tary and volcanic rocks in western Washington, it is inferred that the subtropical belt extended to at least 46° N latitude. The Cowlitz marine sediments were deposited in a very short time, approximately 2 million years. The adjacent Skookumchuck Formation, which is mined in Centralia for coal, contains the same marine invertebrate fauna. Therefore, it may be that the Skookumchuck and the marine section of the Tukwila are coeval. This is a different conclusion from previ- ously published correlation charts (Rau, 1958; Buckovic, 1979). Marine sedimentary rocks from the time period between 39 and 41 million years ago record a regional marine transgres- sion. Geographically, the nearshore marine fauna, and there- fore the coast of western Washington during the late middle Eocene, must have been situated in a narrow belt that extends from near Longview to Centralia and northeast to Tukwila (the most easterly outcrop). To the west of this belt, younger marine sediments subsequently covered the middle Eocene locks. ACKNOWLEDGMENTS Wes Wehr, Don Hopkins, and Jackie Davis, as well as V.
