I have college degrees studying biology, aquatic biology and fisheries. I have worked in the fields of hydrology, aquatic biology, fisheries and forestry for the Environmental Protection Agency, Oregon State University and both the research and land management portions of the U. S. Forest Service. I spent the last seven years before retiring as Forest Supervisor in charge of a 1,000,000-acre national forest. I have shared comments on this project in June of 2023. I have to repeat that there are no good alternatives for a stormwater system in this location at this time. If this site were in a natural condition it would be very difficult to find an adequate solution for dealing with stormwater due to the extensive landslide area, numerous threatened and endangered species and other environmental concerns in Squamish Harbor. The present situation at this site has been made far, far worse by many of the previous actions of the developer. There is a long history of documentation of the many issues of the past. Many of these actions have been in violation of numerous regulations as I document. The best alternative at this time is to let the area heal before allowing any additional construction, removal of vegetation or other disturbance. There should be no approval of additional homes or construction until some healing of the site can occur. There should not be any construction of any kind allowed below and to the east of Linda View Drive. It is my personal observation after decades of working in natural resource management and taking part in planning or supervising thousands of projects that I have not seen projects that have anywhere near the number of threatened, endangered and candidate species for listing (T&E) as in Squamish Harbor and Hood Canal. I included two separate documents in June of 2023 that are part of the record as comments on this stormwater project application. I included discussions of the potential impacts of this proposal on the threatened, endangered and candidate species for listing in this area. One document includes birds, mammals and amphibians. The other document includes salmon, trout, other marine fish, echinoderms and mollusks. I also discussed in those documents the review that was taking place to consider listing bull kelp as a federal threatened species and the proposal for the sunflower sea star to be listed as federally threatened. This proposed stormwater project does have potential impact on a number of T&E species. NOAA Fisheries is proposing to list the sunflower sea star as threatened under the Endangered Species Act. The sunflower sea star (Pycnopodia helianthoides) is the second largest sea star in the world and can have an arm span of more than three feet. From 2013 to 2017, Sea Star Wasting Syndrome caused a major die-off of the sunflower sea stars. The species has suffered a 90% decline across its range, pushed to the edge of extinction over much of the West Coast. Its range used to extend from Alaska into Mexico, but it has apparently now disappeared from the Washington coastline, Oregon, California and Mexico. Scattered populations can still be found in Washington in portions of Puget Sound, including Hood Canal. We have a photograph of a sunflower sea star from the area of the proposed stormwater outfall location (see Marilyn Showalter’s input for more details). Having the stormwater outfall dumping turbid and polluted water directly into the known location of sunflower sea stars needs to have a review or consultation with NOAA Fisheries. NOAA was also reviewing a petition to list West Coast bull kelp as a threatened or endangered species. They have not moved forward with this listing process. The section of Squamish Harbor directly below Termination Point has the only remaining bull kelp in Hood Canal south of the Hood Canal floating bridge. Apparently the amount of floating kelp has been declining for some time in Puget Sound. It is very important to maintain healthy populations of bull kelp and sunflower sea stars. Sunflower sea stars are an important link in saving kelp populations by feeding on sea urchins, a primary consumer of bull kelp. Bull or floating kelp faces several causes of mortality, many exacerbated by human activity. According to the Center for Biological Diversity petition to list West Coast bull kelp as threatened or endangered under the U. S. Endangered Species Act (ESA): Bull kelp requires high nutrient availability, cool water temperatures, and high light availability to thrive and the effectively reproduce…Bull kelp can also be harmed by chemical pollution, like heavy metals and petroleum… Light availability is one of the most important environmental factors for bull kelp growth and sexual maturation…Petroleum also damaged the part of the kelp where the stipe and bulb connect, which is where the kelp grows from. When bull kelp was exposed to unweathered diesel, photosynthesis in blade stopped completely and photosynthesis in the stipe decreased by about 75%. The stormwater plan seems to generally rely on the idea that dumping turbid and polluted water into Squamish Harbor from this project will cause no impact. This is certainly not the case, as I discuss here and in my two other comment documents on T&E species. Having the stormwater outfall dumping potentially turbid and polluted water on the shoreline directly above the location of sunflower sea stars and the only bull kelp located in Hood Canal needs to be thoroughly analyzed. A Biological Opinion may also be required with NOAA to avoid being in violation of the ESA. It is apparent that dumping stormwater in this only location of bull kelp would have a significant impact from the reduction of light penetrating the water column due to increased turbidity. One requirement by the Hearing Examiner could be to require documented communication with the Washington Department of Fish and Wildlife (WDFW) about the need for a Hydraulic permit (HPA). This will ensure a thorough evaluation by WDFW on the location and design of the outfall. Another potential mitigation measure would be to require a sampling system set up to periodically test the water being released into Squamish Harbor. Apparently the proposed stormwater pipe is eight inches in size. If my understanding is correct, it seems like it will be undersized for the volumes of water that will be draining off the developed areas. The Termination Point stormwater plan (section 4.1) discusses the expected increases in stormwater and some of the pollutants that will be contained in the stormwater. These listed pollutants include oil, pesticides, fertilizers sediments and other pollutants. The proposed stormwater plan states in section 4.1 that: Much of the pollution in Puget Sound now comes from stormwater flowing off developed areas, and this influx of water carrying pollutants from developed areas can be damaging to aquatic life and ecology (Hinman et al., 2013). This discussion in section 4.1 continues to go through the problems with dumping stormwater into Squamish Harbor, including the impact of suspended sediment to salmon and other species. It does not consider the addition of the pollution from tires (6PPD and 6PPD-quinone). 6PPD-quinone is deadly to salmon, steelhead trout and other aquatic wildlife. Coho are especially sensitive. There have been numerous problems through the years with this Russell Trask development beginning around 1995. These have included unpermitted drainage, clearing, cutting of new roads, removing earth and stumps while leaving swaths of bare ground, removing large trees around an eagle’s nest, grading and tree cutting, including removal of trees at the base of the unstable bluff. Some of these actions endangered neighbor’s properties. The eagle nest tree next to and just south of Linda View Drive snapped off during a storm two years ago, likely caused by the removal of most of the trees around it and causing it to suffer higher wind velocities. There have also been botched attempts at drainage. The area below Linda View Drive is a well documented unstable landslide area at high risk of slide activity. Russell Trask has been issued citations by the Washington Department of Fish and Wildlife (WDFW), Department of Natural Resources, Jefferson County and the State of Washington. The WDFW cited Russell Trask in October, 2000, for unlawfully undertaking hydraulic project activities, culvert replacement without a permit and land clearing and stormwater construction adjacent to marine waters without a permit. The WDFW thought at the time that the perennial stream, now proposed for the stormwater system, was cutthroat trout habitat. The documentation for the citation stated that much of the vegetation had been cleared from the project site, leaving the entire property susceptible to significant erosion. The biologists were especially concerned with trenches that had been dug to facilitate stormwater runoff. The trenches had been dug to the shoreline of Squamish Harbor, with some earthen outfall directly onto the beach. The biologists state that the trenches presented serious impacts to the adjacent marine habitats. A geotechnical engineer hired by neighbors reported that neighbor’s homes would be safe only if the forestry and vegetation of the entire area was not irresponsibly disturbed. The engineer also reported that the entire location was “dynamic,” and that any new instability in one area would eventually be transmitted to other areas. Under a natural situation the tree and vegetation root systems would aid in lessening the chance of landslides. However, much of the trees and vegetation has been cut and apparently some of the stumps and roots removed. Even after a tree is cut, if the roots are left, they still help hold the soil for some years until they eventually rot and no longer provide this soil stabilizing function. Dr. Derek Booth has done a significant amount of research on Puget Sound and its tributaries. He concludes in his article, “Forest Cover, Impervious Surface Area, and the Mitigation of Urbanization Impacts in King County, Washington, 2000.” On page 3 he states as follows: Modifications of the land surface during urbanization produce changes in both the magnitude and the type of runoff processes. In the Pacific Northwest, the fundamental hydrologic effect of urban development is the loss of water storage in the soil column. This may occur because the soil is compacted or stripped during the course of development, or because impervious surfaces convert what was once subsurface runoff to Horton overland flow. In either situation, the precipitation over a small watershed reaches the stream channel with a typical delay of just a few minutes, instead of what had been a lag of hours, days or even weeks. The result is a dramatically changed pattern of flows in the downstream channel, with the largest flood peaks doubled or more and more frequent storm discharges increased by as much as ten-fold. Dr. Booth continues on page 16: • Land development that eliminates hydrologically mature forest cover and undisturbed soil can result in significant changes to urban stream hydrology and, in turn, to the physical stability of stream channels. • Land development modifies streamflow patterns; even with stormwater detention ponds, it can produce seasonal and stormflow patterns that are substantially different from those to which native biota have adapted. • Although factors other than hydrologic change can undoubtedly affect the magnitude of urban impacts, the breadth of the existing data suggest that improvements in these other factors (e.g., riparian buffers) cannot fully mitigate the hydrologic consequences of overly intense urban development. … Even the largest detention ponds, however, have been recognized as limited in their ability to mitigate all aspects of hydrologic change. • Twenty years of empirical data display a good correlation between readily observed damage to channels and modeled changes in hydrology that correspond to loss of about one-third of the forest cover in a “typical” western Washington watershed. A similar degree of observed damage also correlates to a level of watershed effective imperviousness of about ten percent. Forested areas also provide evapotranspiration which leads to some of the precipitation evaporating and not reaching the ground. When trees are cut, the amounts of stormwater and runoff are increased. This is the opposite of what would be desired above a slide area. When houses are built there are large roof areas and pavement for patios, walks and driveways that no longer allow infiltration of precipitation, leading to even more runoff. The runoff then occurs much more rapidly with higher peaks of runoff than occurs in a natural forest. There have already been some houses built in this development, yet there is no approved stormwater plan and no stormwater system. There has also been recent ground disturbance taking place. One option for examination by the Hearing Examiner is a requirement to use pervious surfaces, but only if reviewed by an expert in the potential to influence the potential of slides. Normally, if there were no slide area, the development could use pervious surfaces, rain gardens and settling ponds as much as possible to infiltrate precipitation and avoid sending high volumes of water to the perennial stream and the sensitive marine waters below with so many T&E species. However, in this case there is a slide area below the proposed development area. The area has been made much more unstable due to the many past unnecessary problems created by improper developer actions. Even if the construction on the lots were kept to the smallest impervious footprint, there will still be a large volume of turbid and polluted water entering the perennial stream. The developer’s report already states that the perennial stream is scoured out. This is normally due to an already larger than normal volume of water being sent to the stream. This scouring has direct downstream impacts carried into Squamish Harbor. The only hope of avoiding further destabilization of the area and preventing impact to the perennial stream, tideland, marine waters and numerous T&E species would be to NOT approve building any additional houses until after the improperly cleared areas are adequately reforested. The WDFW report of violations lists the perennial stream as being cutthroat habitat, but the stormwater plan states that there are no fish. Even if the perennial stream does not have cutthroat trout, it still has a number of aquatic species that should not be eliminated by turning it into the equivalent of a storm drain. There may also be western toads in this area. The western toad, a state candidate for T&E listing, has been observed recently about two miles south of this proposed project. If the waterfall is piped, or if a stormwater pipe is run down the face of the cliff next to the waterfall, then the visual impact needs to be determined. The outfall of the proposed stormwater system is located in waters of statewide significance, including all the marine areas but also includes the shoreline areas. The county needs to have a wetland expert evaluate the proposed development area. Some of the area appears to have wetland species. There has been a new building permit approved by Jefferson County for a home at 122 Linda View Drive, on the north side of Linda View Drive. The County has approved infiltrating all stormwater into the ground at this lot. I assume there will also be infiltration from a septic system. All of this infiltration is located due north of the slide area. To further impact the area, it appears there are (were) two small intermittent streams shaped like a “Y” that come together at the middle area of Linda View Drive (see photographs). There does not appear to be an onsite review of wetlands and temporary streams, both of which would require buffers. The Hearing Examiner needs to mitigate this situation by requiring the developer to submit a wetland and critical area analysis and map those areas before approval of any construction for stormwater, driveways, houses, etc. of any kind is allowed. In summary, there is not an appropriate or workable solution for the stormwater in this development until the damage that has already taken place has more time to heal and for trees and other plants to reclaim the disturbed areas. The present situation is very problematic. Although the existing “stormwater system” is terrible and the new improved stormwater system may be better, it still also has many problems. The county should not be approving more clearing and construction in this area. The county should not consider approving any home or building construction south and east of Linda View Drive under any circumstances. My understanding is that there is a moratorium on any construction in this area, but this needs to be reviewed by the Hearing Examiner. Thank you, Jan Wold
