HomeMy WebLinkAboutSEPA Checklist SEPA Environmental checklist (WAC 197-11-960) July 2016 Page 1 of 22 SEPA ENVIRONMENTAL CHECKLIST Purpose of checklist: Governmental agencies use this checklist to help determine whether the environmental impacts of your proposal are significant. This information is also helpful to determine if available avoidance, minimization or compensatory mitigation measures will address the probable significant impacts or if an environmental impact statement will be prepared to further analyze the proposal. Instructions for applicants: This environmental checklist asks you to describe some basic information about your proposal. Please answer each question accurately and carefully, to the best of your knowledge. You may need to consult with an agency specialist or private consultant for some questions. You may use “not applicable” or "does not apply" only when you can explain why it does not apply and not when the answer is unknown. You may also attach or incorporate by reference additional studies reports. Complete and accurate answers to these questions often avoid delays with the SEPA process as well as later in the decision- making process. The checklist questions apply to all parts of your proposal, even if you plan to do them over a period of time or on different parcels of land. Attach any additional information that will help describe your proposal or its environmental effects. The agency to which you submit this checklist may ask you to explain your answers or provide additional information reasonably related to determining if there may be significant adverse impact. Instructions for Lead Agencies: Please adjust the format of this template as needed. Additional information may be necessary to evaluate the existing environment, all interrelated aspects of the proposal and an analysis of adverse impacts. The checklist is considered the first but not necessarily the only source of information needed to make an adequate threshold determination. Once a threshold determination is made, the lead agency is responsible for the completeness and accuracy of the checklist and other supporting documents. Use of checklist for nonproject proposals: For nonproject proposals (such as ordinances, regulations, plans and programs), complete the applicable parts of sections A and B plus the SUPPLEMENTAL SHEET FOR NONPROJECT ACTIONS (part D). Please completely answer all questions that apply and note that the words "project," "applicant," and "property or site" should be read as "proposal," "proponent," and "affected geographic area," respectively. The lead agency may exclude (for non-projects) questions in Part B - Environmental Elements –that do not contribute meaningfully to the analysis of the proposal. A. Background [HELP] 1. Name of proposed project, if applicable: City of Renton 2021 Long Range Wastewater Management Plan 2.

Proposed timing or schedule (including phasing, if applicable): The City of Renton 2021 Long Range Wastewater Management Plan is scheduled for adoption in 2021. 7. Do you have any plans for future additions, expansion, or further activity related to or connected with this proposal? If yes, explain. No. This Plan lists capital improvement projects planned by the City within the next 10 years and long-term projects over the next 20 years. Proposed locations are shown in the Plan. 8. List any environmental information you know about that has been prepared, or will be prepared, directly related to this proposal. Depending upon the scope of the projects proposed in the Plan, an individual environmental checklist and threshold determination would be completed as specified projects are proposed for construction. 9. Do you know whether applications are pending for governmental approvals of other proposals directly affecting the property covered by your proposal? If yes, explain. At this time, there are no known pending applications for general applicability related to the area covered by the sewer system. There may be applications pending related to improvements to the sewer system such as various on-going plats and developer extensions occurring within the sewer service area. The City plans to adopt the capital improvement plan outlined in this document as part of the City’s 10-year capital improvements plan. 10. List any government approvals or permits that will be needed for your proposal, if known. The 2021 Long-Range Wastewater Management Plan will need to be approved by the Renton City Council and the Washington State Department of Ecology. The King County Utilities Technical Review Committee (UTRC) will review the plan and make recommendations to the Executive and County Council as to the consistency of such SEPA Environmental checklist (WAC 197-11-960) July 2016 Page 3 of 22 items with adopted county policies and codes. King County will review and approve franchises to allow the construction of sewer facilities in county rights-of-way. 11. Give brief, complete description of your proposal, including the proposed uses and the size of the project and site. There are several questions later in this checklist that ask you to describe certain aspects of your proposal. You do not need to repeat those answers on this page. (Lead agencies may modify this form to include additional specific information on project description.) The 2021 Long-Range Wastewater Management Plan (LRWWMP) addresses policies, criteria, assumptions and recommendations for the City's planning area. The major purpose of the Plan is to provide a long range plan for facility improvements necessary to serve the estimated population at saturation. The Plan addresses facility reliability, public health, groundwater and environmental protection, operation and maintenance, and financing issues. The plan also addresses the need to expand Renton’s sewer service area into its Urban Growth Area as the appropriate provider of the urban service per the King County Countywide Planning Policies. This checklist does not address the specific projects addressed in the five year capital improvement program. This is a programmatic checklist and does not address any site specific conditions. These conditions as well as the associated impacts will be discussed in the SEPA reviews of each project. 12. Location of the proposal. Give sufficient information for a person to understand the precise location of your proposed project, including a street address, if any, and section, township, and range, if known. If a proposal would occur over a range of area, provide the range or boundaries of the site(s). Provide a legal description, site plan, vicinity map, and topographic map, if reasonably available. While you should submit any plans required by the agency, you are not required to duplicate maps or detailed plans submitted with any permit applications related to this checklist. The area covered by this comprehensive sewer system plan is the sewer service area as shown in Figure 2.1 of the LRWWMP. Renton has entered into boundary agreements with most of the sewer service providers adjacent to the City. These service boundaries are established and are not generally altered by annexations. B. Environmental Elements [HELP] 1. Earth [help] a. General description of the site: (circle one): Flat, rolling, hilly, steep slopes, mountainous, other _____________ The sewer service area includes steep slopes, several hills, a plateau, and river valley areas. SEPA Environmental checklist (WAC 197-11-960) July 2016 Page 4 of 22 b. What is the steepest slope on the site (approximate percent slope)? The slopes vary from flat (zero percent) to very steep (over 40 percent). Steep slopes exist along the Maple Valley Highway to the north and south of the Cedar River Valley (southern edge of Renton Highlands; northern edge of Scenic Hill and Rolling Hills), along the eastern side of I-405 (eastern edge of the Renton Highlands), along the southern (SR 900) and eastern (Rainier Ave N) edges of Renton West Hill, along the western (SR 167) and northern (I-405) edges of Talbot Hill and the western edge (I-405) of Scenic Hill. c. What general types of soils are found on the site (for example, clay, sand, gravel, peat, muck)? If you know the classification of agricultural soils, specify them and note any agricultural land of long-term commercial significance and whether the proposal results in removing any of these soils. According to the USDA’s Web Soil Survey, the main soil types within the water service area include: Alderwood gravelly sandy loam, Alderwood and Kitsap soils, Arents- Alderwood material, and Indianola loamy sand. Alderwood gravelly sandy loam makes up over 30% of the water service area and is considered prime farmland. Using engineering classifications: there is a wide variety of highly variable glacial deposits in the water service area that include clay, silt, sand, gravel, cobbles, and boulders. In the river valley areas, there is a variety of modern alluvium and undifferentiated deltaic deposits. Adoption of the LRWWMP will not itself result in the removal of agricultural soil. Specific projects that are subject to environmental review will be evaluated for their impact to agricultural soils prior to implementation. d. Are there surface indications or history of unstable soils in the immediate vicinity? If so, describe. Within the City, there are areas of unstable soils including steep slopes and historic coal mines. Some alluvial deposits in the Cedar River Valley and old Black River Valley may be subject to liquefaction during seismic events. Sensitive areas are mapped by the City and are subject to regulation under Renton Municipal Code Title IV, Development Regulations. Specific projects that are subject to environmental review will be evaluated for their soil conditions prior to implementation. e.

Supplemental sheet for nonproject actions [HELP] (IT IS NOT NECESSARY to use this sheet for project actions) Because these questions are very general, it may be helpful to read them in conjunction with the list of the elements of the environment. When answering these questions, be aware of the extent the proposal, or the types of activities likely to result from the proposal, would affect the item at a greater intensity or at a faster rate than if the proposal were not implemented. Respond briefly and in general terms. 1. How would the proposal be likely to increase discharge to water; emissions to air; pro- duction, storage, or release of toxic or hazardous substances; or production of noise? The Long Range Wastewater Management Plan will not itself increase discharge to water, emissions to air, hazardous substances, or production of noise, however, the Plan’s programs and projects have the potential for these effects. For example, projects recommended by the Plan that require construction may result in exhaust emissions, dust, and noise from construction equipment as well as temporary storage of hazardous materials. All hazardous materials storage within the Aquifer Protection Area will be required to comply with the Aquifer Protection Code in order to prevent contamination of the City’s main drinking water source. Specific projects that are subject to environmental review will be evaluated for potential impacts and corresponding mitigation measures prior to implementation. SEPA Environmental checklist (WAC 197-11-960) July 2016 Page 20 of 22 Proposed measures to avoid or reduce such increases are: For the LRWWMP adoption, there are no specific measures planned to reduce these impacts. Best management practices will be used to minimize impacts, in accordance with local, state, and federal laws, during the planning and construction of any applicable projects. Proposed projects will be reviewed and addressed on an individual basis by appropriate agencies prior to implementation. 2. How would the proposal be likely to affect plants, animals, fish, or marine life? Adoption of the LRWWMP will not itself result in direct effects to plants, animals, fish, or marine life. It is not anticipated that any of the proposed projects within the Plan will have an impact upon vegetation or wildlife, however, there is potential for impacts to occur during construction efforts. Specific projects that are subject to environmental review will be evaluated for potential impacts to vegetation and wildlife and corresponding mitigation measures prior to implementation. Proposed measures to protect or conserve plants, animals, fish, or marine life are: Specific projects that are subject to environmental review will be evaluated for their potential impact to plants, animals, fish, and marine life. Potential impacts will be reported with corresponding mitigation measures to protect or conserve vegetation and wildlife. Proposed projects and mitigation measures will be reviewed and addressed on an individual basis by appropriate agencies prior to implementation. 3. How would the proposal be likely to deplete energy or natural resources? Adoption of the LRWWMP will not itself result in the direct depletion of energy or natural resources. It is not anticipated that any of the proposed projects within the Plan will have a strong impact on energy or natural resources, however, some projects may require the use of energy resources. For example, the running or testing of water system facilities uses electricity and construction projects require fuel for equipment operation and delivery of materials. Specific projects that are subject to environmental review will be evaluated for potential impacts to energy resources and corresponding mitigation measures prior to implementation. Proposed measures to protect or conserve energy and natural resources are: For the LRWWMP adoption, best management practices will be used to minimize energy usage. For example, the sewer utility maximizes the potential for gravity flow in the sewer system whenever possible. Programs and projects proposed in the LRWWMP may also result in energy conservation features such as improvements to lift stations and strategies to increase system efficiency. Best management practices will be used in the design, construction and operations of the infrastructure proposed by the Plan, in accordance with local, state, and federal laws, during the planning and construction of any applicable projects. Proposed projects will be reviewed and addressed on an individual basis for energy and natural resources impacts by appropriate agencies prior to implementation. SEPA Environmental checklist (WAC 197-11-960) July 2016 Page 21 of 22 4. How would the proposal be likely to use or affect environmentally sensitive areas or areas designated (or eligible or under study) for governmental protection; such as parks, wilderness, wild and scenic rivers, threatened or endangered species habitat, historic or cultural sites, wetlands, floodplains, or prime farmlands? Adoption of the LRWWMP will not itself result in direct effects to environmentally sensitive areas or areas designated for governmental protection, however, there is potential for the Plan’s programs and projects to occur in the immediate vicinity of sensitive areas. The potential impacts from these actions are currently unknown. Specific projects that are subject to environmental review will be evaluated for potential impacts and corresponding mitigation measures prior to implementation. Proposed measures to protect such resources or to avoid or reduce impacts are: Specific projects that are subject to environmental review will be evaluated by the appropriate agencies for their potential impact and corresponding mitigation measures prior to implementation. All such projects will be required to comply with applicable local, state, and federal guidelines and regulations regarding environmental protection. 5. How would the proposal be likely to affect land and shoreline use, including whether it would allow or encourage land or shoreline uses incompatible with existing plans? Adoption of the LRWWMP will not itself result in direct effects to land and shoreline use and will not allow or encourage land or shoreline uses incompatible with existing plans. Specific projects that are subject to environmental review will be evaluated for land and shoreline use prior to implementation. Proposed measures to avoid or reduce shoreline and land use impacts are: The LRWWMP is designed to support City land use plans, including adhering to the guidelines set by the state Growth Management Act. All such projects will be required to comply with applicable local, state, and federal guidelines and regulations regarding shoreline and land use. Proposed projects will be reviewed and addressed on an individual basis by appropriate agencies prior to implementation. 6. How would the proposal be likely to increase demands on transportation or public services and utilities? Adoption of the LRWWMP will not increase the demand for transportation, public services, or utilities. The Plan itself is partly in response to population growth and increased demands on the sewer utility. Sewer demand projections are included in Chapter 4 of the 2021 City of Renton Long Range Wastewater Management Plan. SEPA Environmental checklist (WAC 197-11-960) July 2016 Page 22 of 22 Proposed measures to reduce or respond to such demand(s) are: The proposed LRWWMP was developed, in part, as a response to increased demands on the City’s sewer utility system. 7. Identify, if possible, whether the proposal may conflict with local, state, or federal laws or requirements for the protection of the environment. The 2021 City of Renton Long Range Wastewater Management Plan does not conflict with any known local, state, or federal environmental laws or requirements. Specific projects that are subject to environmental review will be evaluated for adherence to environmental laws or requirements prior to implementation.
