Tsunami Warnings: Concerns about Response of Local Governments in Lincoln County, Oregon


Because of financial concerns, the proposed Newport Event Center hit a snag in late December 2004 and
has been put on hold.
Links to News-Times articles, Editorials, and Viewpoints both in favor and in opposition to the Event Center after the snag developed begin at 21 December 2004.
There have been so many Letters to the Editor about the Event Center after Dec. 21 that I have not included them, though the link to searching the "Archives" of the News-Times is given. But I have not updated this since April 4.

The Newport Exposition and Event Center is a Symbol of Newport

An excerpt from p. 2 of the 29 September 2004 Conditional Use Permit for the Center states:

"Envisioned as a destination tourist attraction for a variety of regional and national meetings and events, the Expo/Event Center is intended to become a symbol of the City of Newport and its cultural resources for generations to come."

If this is the goal, then the Center needs to be built so that it will last for generations to come. This requires preparing the site and constructing the building to withstand known hazards, which include earthquakes and tsunamis. It is unclear if this will be done or if the City will only build the Center to the minimum standards required and not take voluntary measures to reduce the risk of loss of life from a major earthquake or tsunami.

It is up to the City of Newport to make the Center a positive symbol or a symbol of a city government putting development and money before the safety of its citizens and visitors.


Name of the Proposed Exposition & Event Center Location near the South Beach Marina

The proposed public assembly building was called the Newport Event Center until the Oct. 15 Public Notice about a hearing for the City of Newport's Conditional Use Permit for its construction. In the Public Notice, it is called "Newport Exposition and Event Center."

In newspaper articles and conversations, it is still often referred to as "Event Center." On this web page, it is referred to as Newport Exposition and Event Center, Event Center, or Center.


Structure and Capacity of the Newport Exposition and Event Center

An excerpt from p. 2 of the 29 September 2004 Conditional Use Permit application:

"Envisioned as a destination tourist attraction for a variety of regional and national meetings and events, the Expo/Event Center is intended to become a symbol of the City of Newport and its cultural resoures for generations to come. The Expo/Event Center will feature a main exhibit hall, four meeting rooms, a flexible pre-function lobby space, a full commercial kitchen and food service facility and Expo/Event Center offices when opened in January 2006. In addition, the applicant is proposing a large outside area adjacent to the building's northeast side suitable for supporting an expansion tent for special events. The Area and tent will be used as extensions of the Expo/Event Center's interior space on limited occasions and for limited duration. ... Except for major cultural celebrations like the Seafood and Wine Festival, attendance at events is anticipated to range from 20-3,000 persons."

The size will depend on costs, as an excerpt from a 3 November 2004 article states:

"Port commissioner Mark Fisher asked the size of the structure [Event Center]. Sasaki said it would be 41,000 square feet, down from an original 48,000 square feet, due largely to the rising cost of metal. The Seaside convention center, by contrast, has about 25,000 square feet, Sasaki said. 'I was there, we toured the facility, and the problem is it's so chopped up. The original building and the additions,' he said, 'in my opinion do not flow well now.' The planned main hall for the Newport facility, he continued, is to be 14,400 square feet. Seaside, with two halls, can offer a maximum space of about 10,000 square feet."

It has been proposed to be 36.5 ft tall (p. 3 of the 29 September 2004 Conditional Use Permit application). It may have passive solar lighting on the roof, and initial plans and drawings are in 24 March 2004 and 7 April 2004 articles.

Choice of the South Marina Site for the Newport Exposition and Event Center

The decision to put the Exposition & Event Center near the Port's South Beach Marina was made in December 2003. Previously, the site recommended to the City was the Bunn property west of Highway 101 in South Beach, which the City's subcommittee for locating the Exposition & Event Center reported to not be in a tsunami zone and to have few traffic issues (see 21 November 2001, 4 January 2002, 12 December 2003, and 1 October 2004 articles).

The City was reported to have switched to the site near the South Beach Marina, with the hope that Home Depot would locate a new store on the Bunn property (1 October 2004 article).


Time Table for Construction of the Event Center

On 25 March 2005, the Event Center project is still on hold, see 21 December 2004 update.


Financing of the Newport Exposition and Event Center

The City of Newport has set aside $7.5 million for constructing the Event Center, but the cost estimate available on 8 October 2004 is closer to $9 million (8 October 2004 article). The South Beach Urban Renewal Plan had allocated $5 million, according to a 12 December 2003 article, with additional funding to operate the Center from an increase in the City's transient room tax (see 12 December 2003, 24 September 2004, and 8 October 2004 articles). To get additional funding, the City has applied for a $1 million federal grant (24 September 2004 and 8 October 2004 articles). Because of concerns about Event Center funding, the City Council may also be implementing a 1.5 percent room tax increase on 1 January 2005, rather than in July 2005, as originally planned (17 November 2004 article).

It seems surprising that the City is able to use public funds and to seek a federal grant to build a public assembly building in an earthquake and tsunami hazard area. For example, Oregon's Coastal Natural Hazards Policy Working Group (1994:66) wrote:

"Recommendation 10-4. Prohibit direct public development, grants, loans, or loan guarantees for essential facilities, hazardous facilities, major structures, and special occupancy structures (as defined by ORS 455.477; see Issue 3) in high-hazard areas. Exceptions would be situations where such hazards are fully mitigated by structural or nonstructural means or when the facility cannot be feasibly located outside high-hazard areas (for example, port facilities, marinas, other water-dependent facilities, water and waste treatment facilities, and similar uses). Public subsidies of other types of development in high-hazard areas should generally be discouraged."

Further, the National Tsunami Hazard Mitigation Program recommends on p. 15 of "Designing for Tsunamis: Seven Principles for Planning and Designing for Tsunami Hazards":

"Principle 2: Avoid Development in Tsunami Run-up Areas to Minimize Future Tsunami Losses
"Tsunami risk can be mitigated most effectively by avoiding or minimizing the exposure of people and property through land use planning. Development should be prevented in high-hazard areas wherever possible. Where development cannot be prevented, land use intensity, building value, and occupancy should be kept to a minimum. Where these strategies are not available and development will occur in possible tsunami inundation areas, planners and designers must look to mitigation through site planning techniques as discussed under Principle 3 or building construction techniques as discussed under Principle 4."

The proposed Event Center is a high-occupancy building in a tsunami inundation zone, so it would be a "special occupancy" structure under Oregon Revised Statute 455.447(1)(e)(A). One exception to public funding of building in a hazardous site is if it cannot be located elsewhere, but there are alternate, safer locations for the Newport Exposition and Event Center--it is not water-dependent. The other exception is if the hazard can be fully mitigated by structural or nonstructural methods. The City of Newport has not shown that the Center would be "fully mitigated" for earthquake and tsunami hazards, including the failure of the Yaquina Bay Bridge.

Information about urban renewal programs in Oregon is at Urban Renewal: How Does Urban Renewal Work? by Oregon Department of Revenue (urban renewal funds come from division of Oregon property taxes and special levies) and Oregon Revised Statutes Chapter 457: Urban Renewal. Urban renewal seeks to remove "blighted areas," which Oregon Revised Statute 457.010(1) defines as:

" 'Blighted areas' means areas that, by reason of deterioration, faulty planning, inadequate or improper facilities, deleterious land use or the existence of unsafe structures, or any combination of these factors, are detrimental to the safety, health or welfare of the community."

Some would argue that if the Event Center is constructed in a tsunami and earthquake hazard zone that it seems to be a misuse of urban renewal funds. I telephoned the Oregon Department of Revenue about this on 22 November 2004, and Greg Kramer said that there is nothing in state law to prohibit using urban renewal money to construct a public building in a tsunami and earthquake hazard zone. Greg said that restrictions about what could be funded would be in the local urban renewal plan, which in this case would be the South Beach Urban Renewal Plan. Greg also noted local urban renewal plans are reviewed by the local Planning Commission and City Council are also open to public comments. I have not checked the South Beach Urban Renewal Plan to see if it has any restrictions; if there were any, the restrictions could be readily removed by local government entities that want to build the Event Center using the urban renewal funds that have already been allocated.

Management of the Event Center

In April 2004, the City was searching for a facility management firm to manage the Event Center, and, in May, they agreed to have Compass Facility Management, Inc., of Ames, Iowa do so (7 April 2004 and 19 May 2004 articles). A contract between the City and Compass was agreed upon in November (17 November 2004 article).

An idea of the way that Compass may manage the Event Center can be estimated from November 2004 excerpts from Compass Facility Management, Inc.'s "Action Plan" web page:

"Expense Containment: Compass works with clients to contain and reduce expenses. The two largest expense lines in any facility are labor and utilities. Compass emphasizes efficiency of organization. Compass works to attain the lowest rates possible for such hidden expenses as workers compensation insurance and employee benefits."

"Maximum Usage by Breaking the Rules: At Compass, we believe it is time to re-evaluate the facility usage paradigm. It is no longer acceptable to spend tens of millions of tax dollars on a facility that is used only 100 times a year. By working with community leaders, educators, and service organizations, innovative ways can be developed to allow greater citizen usage of public assembly facilities, without endangering the facility, the budget or the participants."

I wonder how many jobs at the Event Center will be capable of supporting a family or if they will mostly be minimum wage jobs with few or no benefits, including no health insurance.

I wonder if Compass Facility Management, Inc. will notify organizations, groups, or individuals before they register at the Exposition & Event Center that they should bring enough supplies to survive 1-2 days if a major earthquake and tsunami occurs because the Exposition & Event Center is located in a hazardous area and would be isolated if the Yaquina Bay Bridge fails. I wonder if Compass will have earthquake and tsunami warning signs throughout the Event Center and give guests brochures about what to do if there is an earthquake. I wonder if Compass will tell guests that they should evacuate immediately after an earthquake as is recommended in a tsunami inundation zone. I wonder if Compass will give tsunami drills. One way to mitigate the earthquake and tsunami risk is for public awareness and drills, but I wonder if Compass will do so because it may hurt first-time and return business.

What is Soil Liquefaction? on University of Washington's "Soil Liquefaction" web site.

"Liquefaction is a phenomenon in which the strength and stiffness of a soil is reduced by earthquake shaking or other rapid loading. Liquefaction and related phenomena have been responsible for tremendous amounts of damage in historical earthquakes around the world. Liquefaction occurs in saturated soils, that is, soils in which the space between individual particles is completely filled with water. This water exerts a pressure on the soil particles that influences how tightly the particles themselves are pressed together. Prior to an earthquake, the water pressure is relatively low. However, earthquake shaking can cause the water pressure to increase to the point where the soil particles can readily move with respect to each other."
What is Soil Liquefaction? Level 2 states:
"The term liquefaction has actually been used to describe a number of related phenomena. Because the phenomena can have similar effects, it can be difficult to distinguish between them. The mechanisms causing them, however, are different. These phenomena can be divided into two main categories: flow liquefaction and cyclic mobility.
"... Flow liquefaction is a phenomenon in which the static equilibrium is destroyed by static or dynamic loads in a soil deposit with low residual strength. Residual strength is the strength of a liquefied soil. Static loading, for example, can be applied by new buildings on a slope that exert additional forces on the soil beneath the foundations. Earthquakes, blasting, and pile driving are all example of dynamic loads that could trigger flow liquefaction. Once triggered, the strength of a soil susceptible to flow liquefaction is no longer sufficient to withstand the static stresses that were acting on the soil before the disturbance.
" ... Cyclic mobility is a liquefaction phenomenon, triggered by cyclic loading, occuring in soil deposits with static shear stresses lower than the soil strength. Deformations due to cyclic mobility develop incrementally because of static and dynamic stresses that exist during an earthquake."

8 March 2004 Geotechnical Report for the Newport Exposition and Event Center near the South Beach Marina

I first learned of this report (Nickels et al. 2004) during the 25 October 2004 hearing, and I first saw it on Nov. 17.

The City did not state during the Oct. 25 hearing that their geotechnical report would be reviewed independently, so it is not certain that other engineers or geologists would agree with the findings of Nickels et al. (2004). Controversies about geotechnical reports sometimes occur as there were several conflicting geological reports and testimony about landslides for the Jump-Off Joe development in Newport, and the City of Newport chose to rely on a geotechnical report by the developer's geologist that ultimately proved to be faulty. Reliance on single geotechnical reports about landslides also resulted in the City of Newport approving some other developments that failed or later had landslide problems (Sayre and Komar 1989). Elsewhere along the Oregon Coast, reliance on overoptimistic geologists' reports led to the landslide problems at The Capes at Oceanside in Tillamook County (Sleeth 1998). A problem with geotechnical hazard reports is discussed by Oregon's Coastal Natural Hazards Policy Working Group (1994:33):

"Geotechnical site reports are inadequate for making decisions on land development and shore protection projects. Site-specific geotechnical reports, prepared in support of land development projects or shore protection proposals, are especially weak in two areas: assessment of shoreline erosion hazards and evaluation of earthquake and tsunami hazards. Because there are no content standards and review criteria, reports are also inconsistent in content and quality and are sometimes difficult to interpret. These problems with geotechnical site reports may result in inappropriate siting decisions, overreliance on structural shore protection for erosion mitigation, ill-conceived capital expenditures for infrastructure, indirect public subsidies of private development, and potentially, the loss of life and property."

The cover letter for the Event Center's geotech report indicates that Nickels is a registered Oregon professional engineer, Maitland a professional engineer, and Fiedorowicz a registered Oregon professional geologist. The cover letter also states that their study and report "fulfills requirements presented in the 1998 Oregon Structural Specialty Code (OSSC), Section 1804 for site-specific seismic hazard reports for essential and hazardous facilities, and major and special-occupancy structures."

Nickels et al. (2004:9-10) noted that free-water at the time of their drilling in February 2004 was about 10 ft from the surface and that they anticipate that water level below the site "corresponds closely with sea level."

Nickels et al. (2004:6) write about earthquake amplification at the Event Center project site:

"According to Madin and Wang (1999), the amplification hazard is considered high to medium in the project area due to the relatively thick deposits of sand, silt and clay alluvium. We concur with this assessment based on our SHAKE study."

Actually, Madin and Wang (1999) indicate that the proposed Event Center site is in the highest amplification hazard class (Appendix A). Nickels et al.'s (2004:15) response to designing for this amplification:

"Results of the dynamic soil response analyses suggest that the randomly oriented crustal event or the subduction zone events will generate moderate ground shaking. However, the spectral accelerations at the ground surface for the three postulated events lie within the UBC [Uniform Building Code] envelope, we recommend using the UBC spectrum for design."

I do not know if there is any disagreement among geological experts about these conclusions by Nickels et al.

Madin and Wang (1999) indicate that the proposed Event Center site is in an area with the highest class of liquefaction hazards (Appendix A). Nickels et al.'s (2004:6-7) comments about the seismic liquefaction risk at the Event Center site [boldface added] are:

"The proposed site is underlain by medium dense to very dense, saturated sand to a depth of [plus/minus symbol] 90 feet. Based on our boring information and previous borings completed prior to filling the area (Dames & Moore, 1978), we have estimated the surficial [plus/minus symbol] 10 feet of sand is fill and native dune sand and bay alluvium extend below the fill to a depth of [plus/minus symbol] 101.5 feet, the limits of our exploration.
"SPT [Standard Penetration Test] data obtained during our work and the Dames & Moore study suggest the surficial fill is dense to very dense and the native sand is medium dense to very dense. However, one uncorrected SPT value of 8 was recorded in BH-2 [Bore Hole 2] at a depth of [plus/minus symbol] 25 feet. This value suggests a relatively thin zone of loose sand exists at depth. Although the zone of potentially loose sand is relatively deep and appears to have a limited lateral extent, a qualitative and quantitative evaluation of liquefaction risk and post-liquefaction ground subsidence is provided.
"Numerous SPT values were completed in the three FEI borings and the Dames & Moore and only one was low enough to suggest a liquefaction risk. However, evaluating risk cannot be adequately assessed using one SPT value. Rather, the collective site data needs to be considered and then the relative liquefaction risk evaluated. First, we noted that the horizontal extent of the sand layer in question is limited, since low SPT values were not observed in adjacent borings completed for our study or the Dames & Moore study. The absence of the loose zone in the surrounding borings suggests the zone is not continuous across the site and may be limited to a relatively small area in the vicinity of BH-2. Second, the sand layer is relatively thin and the non-liquefiable confinement layer (medium dense to very dense sand) overlying the loose material is relatively thick. The thickness of the overlying layer required to prevent level-ground liquefaction-related damage for sites subjected to a range of maximum accelerations was estimated using Figure 9.48 (Kramer, 1996). For a 5-foot thick sand layer confined by 20 feet of non-liquefiable soil, subjected to a maximum acceleration of 0.35g to 0.4g, the figure shows that liquefaction induced ground damage is highly unlikely.
"In a quantitative approach, the factor of safety against the triggering of liquefaction is the capacity of the soil to resist liquefaction (expressed in terms of cyclic resistance ratio (CRR)) divided by the seismic demand placed on a soil layer (expressed in terms of cyclic stress ratio (CSR)). The latest consensus for quantifying liquefaction susceptibility is summarized in NCEER workshop proceedings (Youd and Idriss, 1996). Procedures presented in the proceedings were used, in part, during this study. The CSR was estimated using uniform average shear stress values and the CRR was estimated using the SPT data. A field SPT value of 8 (corresponding (N1)60 [N with subscripts of 1 and 60] of 13) was recorded in the sand layer or lens. The method using SPT data for evaluating the loose sand indicates that the seismic demand exceeds the resistance which implies the risk for triggering liquefaction is high.
"The relative earthquake hazard maps prepared by Madin and Wang (1999) suggest the site is in an area with a high liquefaction risk. However, the maps are not intended to replace site specific studies.
"The analysis based on one SPT value suggests that there is a risk of liquefaction triggering in the isolated, deep lens of loose sand. Evaluations completed on the remaining strata using SPT data revealed a factor-of-safety of greater than 1 against liquefaction. In addition, the qualitative information presented above also suggests liquefaction is unlikely. Therefore it is our professional opinion that a cyclically induced liquefaction hazard is negligible, and the risk of significant ground subsidence or bearing capacity failure due to liquefaction is also negligible.
"Based on the results of our liquefaction hazard assessment, shallow foundations are recommended to support the structure. In the event the City is still concerned about the liquefaction risk, deep foundations consisting of driven piling are recommended
."

I am not an expert, so I cannot evaluate their conclusions about there being a low risk of both flow and cyclic mobility liquefaction. "Evaluation of Liquefaction Potential" at the bottom of "Why Does Liquefaction Occur? Level 2" on the University of Washington's "Soil Liquefaction" web site discusses the CRR/CSR ratio test that Nickels et al. used and implies that this test applies to all liquefaction, not just cyclic mobility liquefaction, though I am not sure of this.

Tricia Berg with WBGS Architects (the architects for the Event Center) testified at the Oct. 25 hearing; the official minutes for her testimony about the report (Nickels et al. 2004) stated that "the geo tech report did not find that pilings would be needed." Her testimony is true, but the geotechnical report (see last sentence quoted above) also recommended using pilings as an option to making the building less vulnerable to liquefaction if there was a concern.

Nickels et al. (2004:8) notes that the Event Center site is within a tsunami inundation zone and that Oregon Structural Specialty Codes requires seeking advice from the Oregon Department of Geology and Mineral Industries (DOGAMI). I found nothing in Nickels et al. specifically about constructing or designing for tsunamis.

Starting on their p. 15, they give their very specific building foundation and design recommendations based on their geological findings. I am not an expert and am unable to evaluate their recommendations.

Earthquake Hazards in South Beach at the Proposed Exposition and Event Center Site

Earthquake amplification and liquefaction are defined above.

The site of the proposed Center is in the Oregon Department of Geology and Mineral Industries' (DOGAMI) highest earthquake risk category for earthquake amplification, liquefaction, and "relative earthquake hazard" (Appendix A). The City's geotechnical report indicated the amplification hazard risk was high or medium but that the liquefaction risk was negligible. I have no explanation for the differences.

The reasons for earthquake hazards at this site are that it rests on sand dredge spoils and is low-lying. The City's geotechnical report indicates that there is sand and silt down to at least 101 feet below the surface.

The Center would be located in Seismic Zone 4 (the most hazardous zone and which includes all Oregon Coast land west of Range 10 and south of about Otter Rock) according to 1998 Oregon Structural Specialty Codes (State of Oregon 2002a:E-11, Nickels et al. 2004:5).

The timing of a major earthquake is uncertain, since DOGAMI Open File Report 95-67 (see DOGAMI's http://sarvis.dogami.state.or.us/earthquakes/Coastal/Tsumaps.HTM) notes that the estimated chance of a great (Magnitude 8-9) earthquake in the offshore Cascadia subduction zone in the next 50 years "is between 10 and 20 percent, assuming that the recurrence is on the order of 400 ± 200 years and that the last one occurred about 300 years ago." The probability of a great tsunami that strikes the Oregon coast is not included in that estimate. While that probability seems low, recall that U. S. Geological Survey scientists in 1975 predicted that the eruption of Mt. St. Helens "is likely within the next hundred years" (Crandell et al. 1975. Science 187:438-441), and it erupted with loss of life 5 years later.

At the 25 October 2004 Newport Planning Commission meeting for the Event Center's Conditional Use Permit, I gave written and oral testimony about earthquake and tsunami hazards for the proposed Event Center site. I had also written the City of Newport on Sept. 29 and the Port of Newport on Oct. 13 with these concerns, but as of Nov. 22, I have not received a response.


Tsunami Hazard at the Proposed Event Center Site

A tsunami may begin as a single wave that evolves into a series of ocean waves that is generated by disturbances from earthquakes, under-water volcanic eruptions, or under-water or above-water landslides (State of Oregon 2002b:T-1). Tsunamis can be categorized as distant or local in origin, with people having hours to evacuate from a distant-origin tsunami but only minutes from a locally originated tsunami (State of Oregon 2002b:T-1).

The proposed Event Center site is in a DOGAMI tsunami evacuation zone (Appendix B) and below DOGAMI's Tsunami Inundation Zone or Boundary (Appendix C). However, mild tsunamis would not inundate the site, and even a moderately low run-up Cascadia Subduction Zone magnitude 8.6 earthquake is not predicted to affect the Center site (Appendix F). The site would be in danger from a moderately high or high run-up tsunami from a magnitude 9.1 Cascadia subduction zone earthquake (Appendix F) or from very large distant tsunamis.


Yaquina Bay Bridge Failure After an Earthquake Could Isolate Event Center

One of the approval criteria on p. 6 of the 29 September 2004 Conditional Use Permit application for the Event Center is Newport Zoning Ordinance 2-5-3.015(A)(1): "The public facilities can adequately accommodate the proposed use" and the application stated:

"Fire and Emergency Service: Primary and secondary emergency vehicle access is directly available to the site via the existing public street system. ... Based on existing transportation and water facility availability, the proposed use can be properly served by public emergency services."

The last statement is true unless there is an earthquake or tsunami that damages the Yaquina Bay Bridge, so that it is impassable. In a 1997 analysis by the Oregon Department of Transportation (ODOT), the Yaquina Bay Bridge was the number one bridge in Oregon for earthquake preparation because it is vulnerable to a "moderate" earthquake and is part of a "lifeline route" (22 June 2001 article). If the Yaquina Bay Bridge fails, it would cut-off emergency responders and supplies from the Newport side of the Bridge going to the South Beach Event Center and the Port's desired hotel, motel, and/or restaurant. People, who may be lucky to escape from the Event Center after a major earthquake and tsunami with the clothes on their backs, may then find themselves without emergency medical care and supplies, drinking water, blankets, etc. Excerpts from a 16 July 2004 article indicate that the County will not be able to help.

"But, [County Commissioner] Cowan said, 'we can't do everything for everybody. That is why people, families, businesses, should have plans in place. People need to be able to take care of themselves for 24 or 48 hours with water and food [boldface added], and have emergency contacts known,' so they can contact one family member to get word to others without tying up the phone lines. ...

"Commissioner Terry Thompson warned 'there are some small areas between the bridges, and when I was on the (American) Red Cross board, about three years ago, we identified some of them. But we did not have any services for it. We do have a plan,' he said, referring to the county and to the Red Cross, 'and some equipment and some shelters. But the areas between the bridges could be cut off [boldface added]. It would be good to have blankets and things' in small communities likely to be isolated by collapsed bridges, he said Wednesday."

The landowner of the proposed Exposition and Event Center site, the Port of Newport, is aware of this problem. In a conversation with Port Manager Don Mann during my 7 October 2004 visit to the Port of Newport office, I discussed my earthquake and tsunami concerns about the proposed Event Center at the Port's South Beach Marina. Don noted that all of South Beach was that way. I mentioned that the Yaquina Bay Bridge is predicted by ODOT to fail in a "moderate" earthquake, and if it does, it would cut off visitors to the Event Center from overland help from Newport and that boats in the bay may be damaged by a tsunami. Don added that he was at a meeting where one of the possibilities if the Bridge fails is that it would collapse and block boats from coming in.

In My Oct. 13 letter to the Port of Newport and at the 25 October 2004 Newport Planning Commission meeting for the Event Center's Conditional Use Permit, I gave testimony about the potential failure of the Yaquina Bay Bridge.

Concern about Center: Center May Not Do Well Financially

There was much debate about the Event Center, including whether it would be financially viable; for example, see 4 January 2002, 9 January 2002 and 23 January 2002 articles. Below are recent articles about this subject. To see earlier articles, use "Advanced Search" to search for "event center" in the Newport News-Times newspaper "Archives" for articles older than 14 days.

Predictions are that it will take 6-7 years before the Center breaks even financially, though some think it may take longer (see 4 January 2002 and 23 January 2002 articles).

Concerns that the Port may be hurt financially if the City defaults on the Event Center are discussed in a 18 March 2004 article.

In his Sept. 29 Letter to the Editor, David Allen, who may have been a City Councilor, questions whether the City of Newport can afford to build and operate the Center because

"Today, the city is struggling to maintain current service levels and its budget picture is bleak at best. ... Although the city may be able to fund an event center with taxpayer money, is it now fiscally responsible to do so?"

In her Nov. 5 Letter to the Editor, Fran Recht mentioned that if Event Center revenues are inadequate that the Port and fishermen may have to pay.

See articles after 21 December 2004 for discussion of financial concerns. The main objections to the Center are that it is too financially risky.


Concern about Center: Loss of Area for Dredge Spoils

During the Oct. 25 hearing, Janet Webster brought up the issue of a loss of dredge spoil sites as a consequence of the Port moving its boat ramp to accommodate the Event Center.

Fran Recht also included this in her Nov. 5 Letter to the Editor, but she did not give oral or written testimony about this at the Oct. 25 hearing, though I emailed her on Oct. 17 about the hearing. However, even if she had brought it up, it would not have been relevant to the Conditional Use Permit because it was not specific to the Event Center location.


Concern about Center: May Not Be Enough Water

Letters to the Editor by Colleen Brown on Oct. 6 and Tom Czuleger on Nov. 3 noted that current city water system has problems, and adding the Event Center will not help. No one testified about this during the Oct. 25 hearing, but with only one Public Notice 10 days before the hearing and without other publicity about the hearing, many citizens may not have been able to testify.

APPENDIX A. Color copies of portions for Newport "Relative Amplification Hazard," "Relative Liquefaction Hazard," and "Relative Earthquake Hazard" maps in I. P. Madin and Z. Wang (1999), "Relative earthquake hazard maps for selected urban areas in western Oregon: Newport. Oregon Department of Geology and Mineral Industries (DOGAMI) Interpretive Map Series No. 10 (IMS-10). They show that the South Beach area is in the HIGHEST risk categories. The whole maps and explanatory text for the maps are at http://nwdata.geol.pdx.edu/DOGAMI/IMS-10; each whole map is large (1.8-2.0 Mb).

This 1999 report is described in a DOGAMI press release "Earthquake Hazard Maps Released for Coastal Oregon at http://sarvis.dogami.state.or.us/news&events/archives/18-cstlmaps.htm

APPENDIX C. Color copy of upper portion of DOGAMI's Open File Report O-95-29 (Newport-South) that is available at http://sarvis.dogami.state.or.us/earthquakes/Coastal/Tsumapsbycity.HTM that shows that the Port's South Beach area is below the Tsunami Inundation Boundary. The whole map is large (3.6Mb).

The DOGAMI press release describing these maps is at http://sarvis.dogami.state.or.us/news&events/archives/9611-rel.htm. It indicates that:

"Each map has a line that shows how far inland and uphill a tsunami caused by a magnitude 8.8 undersea earthquake is expected to go. The new maps were developed to implement Oregon Revised Statutes 455.446 and 455.447, a law passed by the 1995 Legislature to restrict construction of certain types of essential facilities and special occupancy structures within the tsunami inundation zone."

APPENDIX F. Color copy of portion of Oregon Department of Geology and Mineral Industries' 1997 Interpretive Map Series IMS-2, "Tsunami Hazard Map of the Yaquina Bay Area, Lincoln County, Oregon." This map does NOT appear to be available online. The press release is at http://sarvis.dogami.state.or.us/news&events/archives/9804-REL.htm

This press release also cites another publication about tsunamis at Yaquina Bay entitled "Cascadia Subduction Zone Tsunamis: Hazard Mapping at Yaquina Bay, Oregon. Final Technical Report to the National Earthquake Hazard Reduction Program," that was released in December 1997 as DOGAMI Open-File Report O-97-34. This also does not appear to be available online.

The map symbols and the map are somewhat confusing, but most of the South Beach area would be inundated from a moderately high or high run-up tsunami from a magnitude 9.1 Cascadia subduction zone earthquake but NOT from a moderately low run-up magnitude 8.6 earthquake.
