Rally for 74, Orca Task Force Recommendations Released

Washington State Governor Jay Inslee received a list of 36 recommendations in a report made by the Southern Resident Orca Task Force on Friday.  

Inslee said he and his staff will review the recommendations and assess each one for the most impact in the short and long-term. 

The report is available at:
https://www.governor.wa.gov/sites/default/files/OrcaTaskForce_reportandrecommendations_11.16.18.pdf?utm_medium=email&utm_source=govdelivery

One of the draft recommendations discusses the potential breaching or removal of the Lower Snake River Dams, but couched it in terms of not interfering with the current Columbia River Systems Operation National Environmental Policy Act (NEPA). 

For some, that spells indefinite delays in the process.

The Southern Resident Killer Whales do not have time. The population has declined to 74, which is the lowest number of Southern Residents in more than three decades.

In response to the release of the report, an “Orca Formation of Mourning,” was held on the steps of the Temple of Justice Friday afternoon in Olympia.

The event was organized by the Sea Shepherd Conservation Society, a non-profit, marine conservation organization based in Friday Harbor on San Juan Island, Washington.

The group urged Governor Inslee to call Lt. General Todd Semonite of the U.S. Army Corps of Engineers and demand the immediate breach of the Lower Snake River dams. 

An environmental impact statement already in place suggests breaching the dams and could be chosen by the Army Corps of Engineers.

Seventeen seconds of silence was also held in honor of Tehlequah and her calf. Tehlequah was the orca who birthed a calf and held onto it past its death for 17 days last August.

Indigenous speakers at the rally included Jesse Nightwalker, his mother Carrie Chapman Schuster Nightwalker, and his sister Della Ann James Cootes, all of the Palus (Palouse) Tribe. Jesse Nightwalker said that he attended every meeting of the task force.

The Nightwalkers also delivered a petition, “Recommendation 74,” to the Governor’s Office calling for the breaching of the Snake River dams so the Southern Resident Orcas may enjoy their right to life, which includes their food source, the Chinook from the Snake River Watershed.

Later, activists chanted, “Tell the Corps to Breach All Four,” in the hall outside the Governor’s Office, meaning all four dams. The Governor did not make an appearance.

“We seek to have the dam removal agreement of 50 years ago, made with two Senators, Jackson and Magnuson, who promised to remove the dams with a handshake agreement with my grandmother, Mary Jim Chapman. We seek to have the state honor the agreement indefinitely,” said Jesse Nightwalker.

“This is a formal request of the Palus (Palouse). The Dams on the Snake River have forever been the bane of our existence. Our family was taken away from our land after existing there in the last living encampment there, for over 14,000 years. 

As an endangered human species, our survival was tied to the provision of fishing Salmon, gathering, and hunting on the lands surrounding the Snake River. We were wrongfully removed by the government, like an orca put into a tank miles away from home, to make way for the Army Corps of Engineers to build the dams and were promised to be able to return after 50 years,” he wrote in his petition to Governor Inslee.

Michelle Seidelman, rally organizer with Sea Shepherd Conservation Society, Portland, stands to their left.

Where there were once millions of wild Chinook, there are now less than 10,000, said Howard Garrett of the Orca Network.

“The orcas are starving. The monster dams are killing fish and orcas, and worst of all, there is no real need for four deadly dams on the lower Snake River,” he said.

Garrett and other speakers expressed impatience with the 45 member task force.

“They’ve been asked to come to a consensus about where to place priorities that are guaranteed to impact, sometimes severely, the vested interests and economic future of their own identity group,” he said.

But also said there were good things in the report, he said, including salmon and forage fish enhancement, toxin reduction and the need for funding and legislation action, and breaching of the dams, someday.

Southern Residents are classified as endangered in Washington and surrounding waters, under the U.S. Endangered Species Act and in Canada under the Species at Risk Act.

According to the task force, three primary factors threaten Southern Resident populations: prey availability, legacy and new toxic contaminants, and disturbance from noise and vessel traffic.

Recent studies indicate that reduced Chinook salmon runs undermine the potential for the Southern Resident population to successfully reproduce and recover.

Both Southern Residents and Chinook salmon populations are adversely impacted by warming oceans and ocean acidification due to climate change.

Presence of contaminants and accumulation of pollutants in Washington’s waters are also linked to the decline of Southern Residents. Key sources of contamination in stormwater runoff remain to be addressed and the potential for a catastrophic oil spill continues to threaten Southern Residents and the entire ecosystem of Puget Sound.

In addition, increased boat and ship traffic has caused greater underwater noise that interferes with Southern Resident critical feeding and communication.

Inslee Statement

In a statement released earlier in the day about the task force, Inslee said that the resulting process “brought together diverse voices from a variety of perspectives, yet all had the same goal – to protect and recover these iconic and endangered creatures.

“These recommendations include the weight of extensive public engagement and feedback. We heard from thousands of people from all over the state, region and the world who are very passionate about saving these animals,” he said.

The task force, co-chaired by Stephanie Solien and Les Purce, will continue its work in 2019. The executive order charges the task force with producing a second report outlining the progress made, lessons learned and outstanding needs by October 1, 2019.

Sea Level Rise: Olympia is not Alone


Above: Regional elected officials met last Wednesday evening at Olympia City Hall to discuss sea level rise response planning efforts. Members of Olympia, Lacey, and Tumwater city councils, the Port of Olympia, Thurston County, and the LOTT Clean Water Alliance were in attendance.

Regional elected officials met January 31 to discuss the threat of sea level rise and began planning efforts to save downtown Olympia.

A sight rarely seen to discuss a singular issue, members of Olympia, Lacey, and Tumwater city councils, the Port of Olympia, Thurston County, and the LOTT Clean Water Alliance were in attendance at Olympia City Hall. 

Over 100 assets in downtown Olympia have been identified and categorized and a plan for phasing in specific actions, with an eye toward long range strategies, will begin. 

Justin Vandever of AECOM, the consultant firm hired by the entities, presented the latest sea level rise science specific to downtown Olympia. 

“We know the science is going to change…every few years we’re going to get new information. The likely sea level rise scenario will be 13 inches by 2050, and 36 inches by the end of the century…but there’s a lot of uncertainty…the high range is 24 inches by 2050,” he said.

Reminding officials that Olympia is not alone, Vandever provided examples of other cities, port districts and water and wastewater treatment plant facilities that are also facing sea level rise challenges.

Despite his experience in working with various entities, Vandever said Olympia is unique and its plans and ideas need to be relevant and flexible to the area, which includes three miles of shoreline.


Most of the graphics were overwhelming, eliciting a range of emotions, questions and comments.

Port of Olympia Commissioner EJ Zita expressed her views on mitigation and adaptation. 

“...Much of the hometown we love is going to flood. We have no choice but to adapt. Meanwhile, we can still make choices to mitigate - to slow or reduce climate change. By choosing to encourage dense urban development, especially on higher ground, we can make transportation more efficient, and preserve farmland and open spaces. By choosing renewables instead of coal in Washington State, we can make electricity cleaner. And by installing more charging stations, we can electrify vehicle transport.


“Ports can play a major role in mitigation. By cancelling the biggest oil terminal in the U.S., the Port of Vancouver discouraged oil transport and burning. Our own Port of Olympia could choose not to support fracking for fossil fuels,” she said.  

Lacey Deputy Mayor Cynthia Pratt focused her concerns on infrastructure, such as roads, bridges, fire and police stations, and the LOTT Cleanwater Alliance water and wastewater treatment plant.

“The plant represents a community investment of over $500 million dollars, and it is critical infrastructure that is essential to the continued protection of public health and our environment. It needs to be protected from sea level rise.”

She said she often hears from Lacey residents that they don't have to deal with sea level rises issues and asked Mike Strub, executive director of the LOTT Cleanwater Alliance, to explain what the impact would be to Lacey.

When Lacey toilets back up, then they will care, he quipped. Quickly getting serious, however, Strub explained how sea level rise will impact the whole region.

“There will be an impact on all communities. The process (of inundation) would cause the system to shut down. The Budd Inlet Treatment Plant is the mothership of the treatment system. We can keep it going for a little while, but if we lose power, we cant get water through the plant. It wouldnt go anywhere. It would be a serious situation. Its a fragile line. Once thats crossed, there are serious consequences.

Pratt, who serves as Laceys representative to the LOTT Board, elaborated on her concerns to Little Hollywood after the meeting:

“LOTT will need to keep updating equipment, such as generators and pumps, which will add costs to ratepayers. I think that is an important element for Lacey because they don’t get the connection between us and Olympia’s “problem.” It’s an out-of-sight, out-of-mind issue. Obviously, if LOTT fails, there will be issues, but it also means that wastewater spills untreated into Budd Inlet....I truly think this conundrum needs to be addressed in the outreach plan. It isn’t just an Olympia, LOTT facility, Port problem but rather a system-wide issue.” 

Olympia City Councilmember Jessica Bateman asked several questions about Capitol Lake, and the assumptions used, given the possibility it could revert back to an estuary. 

The state Department of Enterprise Services is responsible for lake management. 

Andy Haub, City of Olympia water resources director for public works, responded that Capitol Lake is in the inundation zone and the intent of a plan is to accommodate whatever Capitol Lake becomes.

Port of Olympia Commissioner Bill McGregor mentioned his concerns about the protection of Cascade Pole, the former wood-treating site on port property that requires an on-site pumping and treatment system to remove contaminants from groundwater. He wondered why the state wasnt involved in protecting its investment, since it has spent millions cleaning up the area. 

Haub admitted that Ecology nor the Department of Natural Resources has expressed interest.

Olympia City Councilmember Clark Gilman said it was hubris to try and defend what downtown looks like now and urged that environmental and social justice organizations be involved in the public planning process.

City of Tumwater councilmember Tom Oliva asked about plans to finance sea level rise planning strategies.


Haub said governing a financing plan will be hard to sustain for decades, and an umbrella organization, such as a levy or flood protection district, could be implemented.

Olympia Community Responds to City Sea Level Rise Report

Community Members Offer Sea Level Rise Comments, Solutions

By Janine Gates
www.janineslittlehollywood.blogspot.com

The underlying message by City of Olympia public works staff to city leaders last week, that sea level rise planning must become incorporated into responsible community conversations and downtown land use decisions, seemed to take councilmembers by surprise.

After all, the message was in conflict with the fact that the council has moved forward on multiple downtown development projects in precisely the area destined to be first impacted by sea level rise.

Disregarding past reports and persistent community voices, the city embraced the massive 123 4th Avenue housing project, and allocated $250,000 to form a downtown strategy. That money came from 2014 year end savings and is anticipated to be adopted at the end of 2016.

To encourage new development, the city recently hired an economic development director, and is hammering out a downtown Community Renewal Area (CRA) plan. Begun in 2013, the effort now needs $40,000 more to complete its work with its legal consultant. The city also approved $35,000 for developer Walker John and his company, Urban Olympia, to scope out a plan of work for the aptly named Water Street Redevelopment Area.

The total CRA budget revised for 2016: $342,500.

In an oral staff report provided to the city’s Community and Economic Revitalization Committee (CERC) on February 8, it was noted that the same developer is moving quickly in his efforts to develop the parcels owned by the Port of Olympia bordering State and Cherry Street, across from the Hands On Children’s Museum. Concept plans have already been drawn up by architect Ron Thomas.

As the council subcommittee bantered around their work plan goals, questioned whether or not a CRA is really needed given the fact that the economy is moving, and welcomed the planning of two developer roundtable discussions specific to the downtown strategy by the end of March, the words “sea level rise” were never spoken.

Above: Walking along Percival Landing near Sylvester Street on December 18, 2015, electrical boxes and lighting components behind the Oyster House are clearly submerged by Budd Inlet. The tide was 16.2 feet at the time this picture was taken. 

Community Efforts and Responses to Sea Level Rise Report

Given downtown Olympia’s proximity to Budd Inlet, the sheer amount of engineering that needs to occur to prepare downtown Olympia for climate change and sea level rise is almost unimaginable.

But some South Sounders have offered their expertise, thoughts, and solutions on the matter for years.

Following the sea level rise report delivered by staff to Olympia city council on February 9, community member and economist Jim Lazar issued a few ideas during public comment period.

“Aberdeen and Hoquiam require all new buildings in their downtown areas to mound up their building sites at least three feet. We can do that here. Some people have said that we will not abandon downtown. If that’s what you believe, start budgeting like you mean it. The engineered response to sea level rise will cost tens of millions of dollars.”

Saying he was the part owner of a downtown business, he requested that the council poll downtown business owners to see if they were willing to approve a two million per year local improvement district or diking district levy to start paying for this.

“…But if the owners of these buildings are not willing to invest what it will cost to protect their investment, maybe that tells us something. If asked…I would vote no unless there was some certainty that a long-term plan was in place, adequately funded, and likely to succeed. A reasonable plan would be to impose a development moratorium on the low-lying parts of downtown until a plan is perfected, and funding is assured,” said Lazar.

Community member Daniel Einstein immediately submitted a letter to councilmembers, taking issue with staff comments that without the dam, the lake would flood more frequently.

“An important question is, how do we translate those 2007 Capitol Lake Adaptive Management Plan (CLAMP) report findings ten years down the road when sea-level rise must now be considered inevitable? There is no perfect translation of course, but here are a few things to consider,” he wrote.

“First, as sea-level rises, the 5th Avenue dam will become inoperable. Tides will flow back into the basin no matter what we do. In other words, given the forecasts…the dam will not be relevant. Second, a lot has changed from a regulatory point of view since the dam was constructed. There is no way a new, higher dam would ever be permitted, even if it could be engineered.”

“An additional point to be considered is that the lake is filling up rapidly with sediment. As it does, its capacity to hold water decreases making flooding more likely. This was the Deschutes Estuary Feasibility Study’s (DEFS) conclusion. If the estuary were restored there would be more capacity for the rising sea - more room for the waters to flow.  As it is now, there is no depth in the “lake” and a dam plugging up the system. However, when the DEFS was done sea-level rise was a less thought of phenomenon….

“I do believe this is an issue that we should look into further as we decide what and where to protect and how to pay for it. It is also something to consider as we decide the future of the isthmus,” wrote Einstein.

Sue Patnude of the Deschutes Estuary Restoration Team (DERT), a local nonprofit, also weighed in:

“....The lake is getting shallower and shallower, eliminating its capacity to hold water, and the dam is in disrepair. Constant repair and money will be needed to monitor the ability of the dam to function in the future. It is old, and should it fail in a closed position, flooding will be inevitable.”   

Patnude said the state Department of Enterprise Services (DES) has proposed $500,000 in its capital budget for routine inspections of the dam and upgrades to the service life of the facility within the resources provided. The dam was built in 1951.

Above: Roger Horn stands on Percival Landing near Bayview Market on December 18, 2015. The tide, at the time this picture was taken, was 16.2 feet. The high tide for December was 16.4 feet. Percival Landing was constructed in three phases in the 1970s and 1980s.

Upon hearing the report, Roger Horn, a former, longtime member of Olympia’s Planning Commission, became concerned about whether or not the 30 foot setback as stated in the city’s new Shoreline Master Plan is going to be enough for new construction.

“In terms of possible solutions, I’d prefer on-shore berms to bulkheads or seawalls….The first thing that came to my mind was the Percival Landing replacement project and how that project will address sea level rise since super high tides already come within inches of businesses at Fourth and Water Street,” he told Little Hollywood.

Phase two improvements for Percival Landing are slated for the area around Water Street and the Oyster House restaurant, near The Kiss statue. To ensure continued progress towards the replacement of Percival Landing, the city’s current capital facilities plan budgets $199,000 for design efforts, to be spent in 2016. Actual initiation of the project is not scheduled to occur for several years.

TCAT Survey Reveals Possible Local Solutions

Another non-profit, the Thurston Climate Action Team (TCAT), recognized the risk of sea level rise to the city, and inventoried greenhouse gas emissions in Thurston County and its cities.

Recently, TCAT led a detailed survey of attitudes within the county on energy and climate change and the willingness to address it financially.

One survey question asked, “If nothing is done to reduce global climate change, how serious of a problem do you think it will be for Thurston County—very serious, somewhat serious, not so serious, or not serious at all?”

Combining the “very serious” and “serious” responses, 76 percent of respondents believed there will be serious local consequences for not addressing climate change.

Respondents were asked about their willingness to personally contribute money for renewable energy and energy conservation projects and what kind of taxing mechanism they would prefer for financing those efforts. Dollar ranges were provided as options. 

Over 75 percent of respondents indicated they were willing to pay something to promote renewable energy and energy conservation, and a solid majority, nearly 69 percent, were willing to pay at least $10 per year.

Another surprising result was the number of people willing to pay over $60 per year. Among those willing to contribute, the highest number, nearly 22 percent, indicated they would pay over $120 per year. To generate those revenues, nearly 63 percent mentioned they would support a tax increase of some sort.

“This creates an opportunity for local governments (county, city, PUD, Port and others) to coordinate a county wide effort to encourage and incentivize the use of clean energy. A reasonable next step toward creating a county-wide clean energy program would be a collaborative design effort led by local government, completed in a relatively short period of time,” says the report.

The report was completed in September 2015 with financial support from Thurston County and LOTT Clean Water Alliance and faculty participation by The Evergreen State College, Saint Martin’s University, and South Puget Sound Community College.

Tom Crawford, vice president of TCAT, is leading the Climate and Clean Energy Work Group within Thurston Thrives. Thurston Thrives is the county Board of Health's initiative to engage the community in taking action to improve the health of Thurston County's population. The environment is one of the nine key areas. 

“These survey products become resources to form a solid foundation for local solutions,” said Graeme Sackrison, former mayor of Lacey and board chair of TCAT.

Olympia Grapples with Flood Management, Sea Level Rise


Above: Under a surly afternoon sky, City of Olympia and Washington State Department of Enterprise Services staff were on flood watch and ready with sandbags at Capitol Lake in the late afternoon of December 10, 2015. “It’s a bit of a dance,” said Andy Haub, City of Olympia director of water resources, of the flood management process and roles played by the city and state.

City Staff Clarify Statement That Dam is Needed to Control Downtown Flooding

By Janine Gates

The stunningly frank sea level rise report delivered by city public works staff to Olympia councilmembers earlier this week was loud and clear: develop a vision and a plan to begin adapting to sea level rise. Like, now.

But even without the extra burden of sea level rise, the protocol for managing current flood events in downtown Olympia requires a highly managed rapid response involving state and local agency coordination.

Above: When the lake gets too high, the city stormwater system backs up. A valve, located under Water Street, is shut off, preventing lake water from flowing “up” the stormwater outlet to the lake and discharging to the catch basin in the streets at Columbia and Water Street. A pump takes the stormwater and puts it into the lake.

The Department of Enterprise Services (DES), the state agency responsible for managing the 260 acre lake, regularly releases as much water through the 5th Avenue dam as each low tide allows.

DES closely monitors weather forecasts, streamflow on the Deschutes River, tide tables and more to determine when to lower the lake below the normal winter level in advance of major storms.

On December 10, 2015, a combination of record-setting rainfall, flooding on the Deschutes River and high tides in Puget Sound caused flooding around Capitol Lake and Heritage Park. So, when DES staff determined that the lake was going to flood, the department notified the City of Olympia and closed a section of Water Street and 7th Avenue.

The city implemented its flood response plan which includes pumping excess stormwater directly into Capitol Lake and placing sandbags in the area to protect nearby businesses.

By their own admission, city staff underestimated the rate at which the lake was rising and were later than usual in closing a valve, resulting in lake water flooding the streets and coming to within inches of the doors of Olympia Supply and other local businesses.

On December 11, 2015, the day after the somewhat minor flooding incident, Little Hollywood interviewed Andy Haub, City of Olympia director of water resources, who was onsite with staff during the emergency.

LHTell me about this valve...the water got to within four inches of Olympia Supply's doors. 
 
Haub: We close the valve in order to prevent lake water from flowing “up” the stormwater outlet to the lake and discharging to the catch basin in the streets at Columbia and Water. The pools of water in the streets are lake/Budd Inlet water.   Usually we close the valve before the lake starts backing up. Then, the only water we pump is precipitation from the Columbia and Water Street area. In other words, once we shut the valve in the stormwater pipe, we have to pump the upstream stormwater.

Yesterday (December 10, 2015), we underestimated the rate at which the lake was rising and so were later than usual in closing the valve. Once we started the pump, the water in the streets declined very quickly - 15 minutes….

LH: I was told that the Capitol Lake area is the lowest catch basin in downtown.

Haub: The two block area around Columbia and Water Street is the only real area that is at risk from flooding due to the lake backing up. At some point, the lake can't hold it all, so that's why DES folks were standing around (in the afternoon) waiting to see if the tide would rise too high, plus the water in the lake would make it all overflow like a bathtub. When the Deschutes is flowing very high, the State lowers the lake by opening the 5th Avenue dam during the low tide preceding the high tide. Then they close the dam when the tides turn to a high tide, thereby keeping the high tide out of the lake and providing room for the river flows. It’s a bit of a dance….

LH: Is that portable pump station always going to be down there with chain link fencing around it if it seems like this is a permanent problem area? 

Haub: We keep one of the pumps there during the peak of the winter.

Haub explained that other factors such as barometric measure, wind direction and speed, temperature, low pressure systems and the effect they have on high tides also dictate Olympia’s flooding risk.

“It’s very interesting to think about and understand. Our high tide was 1.95 feet higher than predicted, simply due to low barometric pressure. You and your audience would find this dynamic interesting….” said Haub.

LH: If this whole area reverted back to an estuary, would we even we worrying about all this?

Haub: Same dynamic.

At that point, Little Hollywood had taken up enough of Haub’s time.

Fast Forward: Capitol Lake, The Dam and Flood Clarification

Along with Haub, Eric Christiansen, City of Olympia water resources planning and engineer manager, provided the staff report at last Tuesday night’s council study session on sea level rise issues.

Councilmember Jessica Bateman asked how its reverting back to an estuary would impact downtown and Christiansen responded that without the dam, downtown would flood more frequently.

This short response confused and alarmed community members active with lake management conversations.

On Thursday, Little Hollywood asked Christiansen to clarify his response to Bateman, which was in conflict with the Capitol Lake Adaptive Management Plan’s (CLAMP) final Deschutes Estuary Feasibility Study report of 2007.

The report says, in part:

“...The City of Olympia may require a FEMA-approved floodplain study as part of the permitting requirements for the proposed restoration project. However, it can be concluded that flooding in the restored estuary will be similar to current (managed lake) conditions at worst. A decided advantage of the restored estuary is that flood management will no longer depend on the correct functioning of a mechanical system – flooding under current conditions can be considerably exacerbated if the tide gate controls should fail.”

Christiansen responded:

“I maybe partially misspoke. There are a few blocks of downtown between Water and Columbia and 5th and 7th streets that are at a very low elevation, approximately two feet below the flood elevation. There are about 19 storm drain pipes that connect that area and the park with Capitol Lake. Only two of those pipes that I am aware of have valves to prevent water from flowing backward into the streets. The State manipulates the dam to keep lake levels low when tides are high, thus for the most part keeping water out of the streets. The last six to twelve inches of lake elevation make a big difference. We had about a dozen tides this winter that could have caused flooding.

“Without the dam, the drainage systems will need to be modified by adding additional valves and probably consolidating pipes. It will also help if the ground in key parts of Heritage Park is elevated. The railroad tracks pose an additional challenge,” said Christensen.

Above: The 5th Avenue dam on December 18, 2015.

In conflict with information city staff and local environmental advocates have been providing the city for years, multiple downtown development projects are underway in precisely the area destined to be first impacted by sea level rise. 

These vulnerable areas, built on fill, are well within the historic shoreline of Budd Inlet.
