<h2>We want to hear from you!</h2>Community input is critical as we continue to develop the Lake Washington Wastewater Lake Line Management Plan (Plan). The plan will help us provide reliable wastewater service and protect the Lake Washington ecosystem for generations to come. Since our team has completed the programmatic Draft Environmental Impact Statement (EIS), we are now conducting analysis of viable alternatives.Your feedback is immensely important for the development of the plan. Share your comments with the team by submitting feedback on the question form at the bottom of the page, or by clicking here:<a href="https://www.engagingbellevue.com/lake-washington-line/survey_tools/we-want-your-input"> Provide Feedback</a>, <a aria-label="提供反饋信息 (Chinese) " class="local" href="https://www.engagingbellevue.com/lake-washington-line/survey_tools/we-want-your-input5">提供反饋信息 (Chinese)</a>, <a aria-label="Suministre realimentación (Spanish) " class="local" href="https://www.engagingbellevue.com/lake-washington-line/survey_tools/we-want-your-input1">Suministre realimentaci&oacute;n (Spanish)</a>, <a aria-label="피드백을 제공하다 (Korean) " class="local" href="https://www.engagingbellevue.com/lake-washington-line/survey_tools/we-want-your-input2">피드백을 제공하다 (Korean)</a>, <a aria-label="Обеспечить обратную связь (Russian) " class="local" href="https://www.engagingbellevue.com/lake-washington-line/survey_tools/we-want-your-input3">Обеспечить обратную связь (Russian)</a>, <a aria-label="Cung cấp phản hồi (Vietnamese) " class="local" href="https://www.engagingbellevue.com/lake-washington-line/survey_tools/we-want-your-input4">Cung cấp phản hồi (Vietnamese)</a>.<h3>What is the Lake Line System?<img src="https://s3-us-west-1.amazonaws.com/ehq-production-us-california/152a3d17a6034434ee4fc63cf76ad39fb72a8b3e/original/1693956387/c2890562d0baa2a16e471a1c9f39300a_Picture4.jpg?1693956387" alt="The Bellevue shoreline with several docks and homes and many trees viewed from Lake Washington on a clear day. Buildings in Downtown Bellevue rise above an apartment building in the background."> Lake line management will help Bellevue Utilities protect public health and the delicate Lake Washington ecosystem.</h3>The City of Bellevue&rsquo;s Lake Washington lake lines are an important part of the wastewater system located along the shoreline of Lake Washington. These wastewater pipes are either underwater or on land adjacent to the lake. Lake line pipes carry raw sewage from the shoreline properties to sewer pump and/or lift stations, which in turn, pump the sewage into an upland King County sewer system to eventually discharge into a King County Sewer Treatment Plant.Most of the Lake Washington lake lines were constructed in the 1950s and &#39;60s to prevent raw sewage from being directly discharged into the lake. Half a century later, this infrastructure now serves more than 1,000 community members in Bellevue and neighboring communities. However, the pipes in the lake line system are aging, and the shoreline and in-water location creates challenges for maintenance, repair, and replacement activities. <h3>We need a Lake Line System Management Plan</h3>In 2016, a preliminary condition<img src="https://s3-us-west-1.amazonaws.com/ehq-production-us-california/f50fc358167badde570ff07d5af7ad6b498b2777/original/1693956656/0be7b44eb583a489bb0a992d5e6a2e5a_Picture5.jpg?1693956656" alt="The Lake Washington Shoreline with two workers surveying the water from the shore while a third surveyor walks through the water ">Lake line wastewater pipes are either underwater or on land adjacent to Lake Washington assessment showed varying degrees of aging in the lake line pipes and interior pipe linings. Without advanced planning, the lake line system will begin to fail, potentially causing loss of service to residents and risk to our sensitive lake environment. Line failures could result in property damage to individual homes and widespread contamination of Lake Washington. Bellevue Utilities is developing a management plan for the repair, replacement, and maintenance of the system. The plan provides the framework to help ensure we can continue to provide safe and reliable wastewater service to the community and protect public health and the delicate Lake Washington ecosystem. <h2>Project Location</h2>The Lake Washington lake line system includes approximately 14.6 miles of wastewater lines that are<img src="https://s3-us-west-1.amazonaws.com/ehq-production-us-california/bc558ddc5cf47ef4210322f700fbbf1e6e194d44/original/1694102023/c1d65aa2b674060fb6973406e34c9f0d_COB_ProjectMap_082323_B.jpg?1694102023" style="width: 300px;" class="fr-fic fr-dii fr-fir"> either underwater or on land adjacent to Lake Washington, as well as 15 pump stations and eight flush stations. The pipelines cross through the shorelines of Bellevue, Beaux Arts Village, Hunts Point, Medina, Yarrow Point, and King County. The lake line will be divided into planning areas for analysis and planning. Some areas of the lake line system may not require work; others may require repair, replacement, or continued maintenance.Prioritized areasFor planning purposes, the team has divided the Lake Washington lake line into six service areas:<ol><li>Hunts Point and Yarrow Point</li><li>Evergreen Point</li><li>Medina South</li><li>Meydenbauer Bay</li><li>Killarney</li><li>Newport South</li></ol>The team analyzed the likelihood that the lake line in each of the six areas might fail, and the consequence if that area failed. By combining those two factors, the team developed recommendations for when each area may need repair or replacement.The Meydenbauer Bay service area was ranked as the highest priority with action needed in the next ten years. Following Meydenbauer Bay was:2. Newport South3. Hunts Point and Yarrow Point4. Killarney5. Evergreen PointEach of those service areas are likely to need comprehensive system improvements in the next 10 to 20 years. Medina South was the lowest priority, with system improvements needed in more than 20 years.In each area, there are some early data collection, maintenance and/or operational or repair activities that will be needed in the near term.<h2> </h2><h2>Potential Solutions</h2>The Lake Line System presents multiple technical, environmental, operational, and financial challenges because of its location in and adjacent to the lake. In the future, the project work could have impacts on the environment, as well as property owners and the public. The management plan will help us identify potential solutions and their impacts, laying groundwork for future design and construction projects. Potential solutions could take place in the lake, on land and on individual properties. It is important to note that different areas of the system will have different recommended alternatives - there will not be one alternative recommended for the entire Lake Washington Lake line system. A &ldquo;no action&rdquo; alternative is also an option, and could involve emergency repairs and maintenance.<h4>Alternative 1 - In water</h4><ul><li>Refers to pipes below the ordinary high water of Lake Washington.

Community feedback will be used in the analysis of each alternative to help determine the best options for the management plan.<h2>Timeline</h2>We anticipate completion of the management in early 2024. We need your input now to help narrow down the prioritization and the evaluation criteria described above.
