SEPA ENVIRONMENTAL CHECKLIST UPDATED 2014

Transcription

1 Purpose of checklist: SEPA ENVIRONMENTAL CHECKLIST UPDATED 2014 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: [help] 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 decisionmaking 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: [help] 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.

3 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.) [help] The proposed project will replace the four (4) existing public docks within Memorial Park in the City of Pateros. Memorial Park was constructed by the PUD and is operated by the City of Pateros. As part of the PUD s FERC license for the Wells Hydroelectric Project, the PUD is required to operate and maintain the docks to ensure the continued safe use of the docks by the public. The four (4) existing docks were originally permitted in 1988 and were constructed out of treated lumber and composite wood decking. Floatation was provided by Styrofoam filled tires. The docks were regularly removed during the winter to protect the docks and to repair any damage to the floats. The deterioration of the docks has resulted in the need to completely replace the floats and piling. The proposed project will replace all four (4) docks and associated piling to ensure the continued safe use of the park and docks by the public. The proposed project will entail the demolition of the four (4) floats and piles and installation of four (4) replacement floats and new piles. Overall, the replacement floats will result in an increase of approximately 96 sq ft of overwater coverage; however, based on the design of the floats and gangways the impacts associated with the replacement docks will be less than the impacts of the existing docks. Each of the existing docks consist of a concrete abutment, gangway and floats, which are anchored with steel piles. The docks are pretty much identical with the only difference being the number and configuration of the floats, which are all the same size. The exact configuration of the docks have varied over the years as the floats are interchangeable and have been installed differently each spring (floats removed during the winter to protect them). Although the configuration of the floats has varied over time, the number of floats has not increased keeping them compliant with the existing permits. The concrete abutments are all located landward of the OHWM and provide access from the existing trail to the docks. The concrete abutments are located at approximately the top of the bank within the riprapped portion of the shoreline. The abutments all have steps and handrails and will be modified as part of the project to make them ADA compliant. All gangways are constructed of wood timber frame and composite decking. For ease of permitting, the existing docks have been labeled docks 1-4 and will be described as permitted. Docks 1 and 4 are the most downriver and upriver docks and each consists of an 8 ft by 20 ft gangway that extends from the concrete abutment to two (2) floats. The existing floats are 8 ft by 20 ft and framed with treated lumber. The floats are covered with solid decking and floatation is provided by either Styrofoam filled tires or plastic float tubs. The floats are deteriorating and the floatation on some of them has disappeared causing the floats to list. The dock is anchored by two steel piles. The existing overwater coverage of each of the docks are 480 sq ft for a total of 960 sq ft. Dock 2 is the immediately upriver of Dock 1 and consists of an 8 ft by 20 ft gangway that extends from the concrete abutment to four (4) floats. The existing floats are 8 ft by 20 ft and framed with treated lumber. The floats are covered with solid decking and floatation is provided by either Styrofoam filled tires or plastic float tubs. The floats are deteriorating and the floatation on some of them has deteriorated causing the floats to list. The dock is anchored by two steel piles. The existing overwater coverage of Dock 2 is 800 sq ft. Dock 3 is the immediately upriver of Dock 2 and consists of an 8 ft by 20 ft gangway that extends from the concrete abutment to five (5) floats. Three of the existing floats are 8 ft by 20 ft and the other floats are 8 ft by 12 ft and 8 ft by 15 ft. All of the floats are framed with treated lumber and are covered with solid decking. Floatation for the floats are provided by either Styrofoam filled tires or

4 plastic float tubs. The floats are deteriorating and the floatation on some of them has disappeared causing the floats to list. The dock is anchored by two steel piles. The existing overwater coverage of Dock 3 is 856 sq ft. The demolition of the existing docks will entail the removal of the existing gangways, floats, and piles. The structures will be removed using either land based or barge mounted crane or excavator. The structures will be at an appropriate upland disposal site. The steel piles will be removed using either a barge mounted crane or excavator. Prior to the demolition, a silt curtain will be installed around each dock that will be demolished to contain any debris. The proposed replacement docks will be slightly different from the existing docks; however, the configuration of the replacement docks will be extremely similar and would result in approximately the same amount of overwater coverage. The replacement of each of the docks will entail the modification to the existing concrete abutment to eliminate the stairs and the installation of a gangway, floats, and pile. The modification to the concrete abutment will allow each of the docks to be ADA compliant, as well as anchor and raise the elevation of the landward end of the gangway. The modification to each of the concrete abutment will entail covering the existing steps and abutment with reinforced concrete. The slope of the new concrete abutments will be 2 percent of less and no steeper that 5 percent longitudinal slope. The modifications will be cast in place and landward of the OHWM. No concrete will be placed within the OHWM and precautions will be taken if high water events occur at the time of abutment modifications. A total of 15.2 cubic yards of concrete will be required to modify the existing abutments. Each of the docks will have slightly different elements and configuration and will be discussed below. Docks 1 and 2 will each entail the installation of a gangway and three floats that will be anchored by three piling. The aluminum gangways for each dock will be 6 ft by 35 ft that will be anchored to the modified concrete abutment on the landward side. The waterward side of the gangway will rest on the landward end of the float and allowed to travel on the float during water level fluctuations. The entire surface of the gangway will be covered with grating with at least 60 percent open area. The floating portion of the docks will consist of an 8 ft by 40 ft float and two 8 ft by 20 ft floats. The floats will be assembled off site and placed into the river either from the upland or at the existing launch. The floats will be constructed of aluminum and would be decked with ADA-compliant grated material, having approximately 60% open area. Flotation for each of the floats will be provided by fullyencapsulated, white flotation tubs. The float framing will have greater than 50% open area (area not covered by framing and floatation tubs). The landward edge of the float for Dock 1 will be approximately 28 ft landward of the OHWM at a water depth of approximately 13 ft. The landward edge of the float for Dock 2 will be approximately 30 ft landward of the OHWM at a water depth of approximately 15 ft. The replacement docks at these locations will be located approximately 10 ft further waterward of the existing dock in order to ensure that the float does not ground out during low water Each of the floats for the two docks will be anchored by three (3) inch diameter steel piles (epoxy coated white or within white PVC). Piles will be driven with a vibratory hammer unless driving conditions require an impact hammer. If an impact hammer is used, sound attenuation measures (bubble curtain and wood block) would be used to minimize underwater noise. Also, piles will be capped with anti-perching pile caps. Dock 1 and Dock 2 will each result in approximately 823 sq ft of overwater coverage, for a total of approximately 1,646 sq ft of overwater coverage. Docks 3 and 4 will each entail the installation of a gangway and one float that will be anchored by two piling. The aluminum gangway for Dock 3 will be approximately 6 ft by 35 ft and the gangway for Dock 4 will be approximately 6 ft by 45 ft. The landward end of the gangways will both be anchored to the modified concrete abutment on the landward side. The waterward side of the gangways will rest on the landward end of the float and allowed to travel on the float during water level fluctuations. The entire surface of the gangways will be covered with grating with at least 60 percent open area. The floating portion of the docks will consist of an 8ft by 40 ft float. The floats will be assembled off

5 site and placed into the river either from the upland or at the existing launch. The floats will be constructed of aluminum and would be decked with ADA-compliant grated material, having approximately 60% open area. Flotation for each of the floats will be provided by fully-encapsulated, white flotation tubs. The float framing will have greater than 50% open area (area not covered by framing and floatation tubs). The landward edge of the float for Dock 3 will be approximately 30 ft landward of the OHWM at a water depth of approximately 12 ft. The landward edge of the float for Dock 4 will be approximately 40 ft landward of the OHWM at a water depth of approximately 10 ft. The replacement dock for Dock 3 will be located approximately 3 ft further waterward of the existing dock, while the replacement dock for Dock 4 will be located approximately 20 ft further waterward of the existing dock. The increased length of the replacement docks are being proposed to ensure that the float does not ground out during low water The floats will each be anchored by two (3) inch diameter steel piles (epoxy coated white or within white PVC). Piles will be driven with a vibratory hammer unless driving conditions require an impact hammer. If an impact hammer is used, sound attenuation measures (bubble curtain and wood block) would be used to minimize underwater noise. Also, piles will be capped with anti-perching pile caps. Replacement Dock 3 will result in approximately 503 sq ft of overwater coverage and replacement Dock 4 will result in approximately 563 sq ft of overwater coverage, for a total of approximately 1,066 sq ft of overwater coverage. The proposed project would result in no adverse effects on the existing nearshore shallow water habitat functions and values at Memorial Park. The replacement of the existing docks will result in an increase of approximately 96 sq ft of overwater coverage; however, this increase in overwater coverage will not result in any adverse impacts (2,616 sq ft of overwater coverage removed and 2,712 sq ft of overwater coverage installed). This is based on the fact that the replacement docks will reduce the overall impacts compared to the existing conditions. The replacement docks will result in a reduction of impacts on the nearshore shallow water habitat in the river and will not require compensatory mitigation. 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. [help] The proposed project is located at the eastern end of Lakeshore Dr in the City of Pateros. There is no parcel number for where the project will occur as the property is along the shoreline within PUD Ownership; however, the property is identified as Block 1, Pateros Replat No. 3. Section 36, Township 30 North, Range 23 East. Existing docks are located at N lat / W long (Dock 1), N lat / W long (Dock 2), N lat / W long (Dock 3), and N lat / W long (Dock 4).

6 B. ENVIRONMENTAL ELEMENTS [help] 1. Earth a. General description of the site [help] (circle one): Flat, rolling, hilly, steep slopes, mountainous, other The property consists of nearly flat uplands with a steep slope from the top of the bank down to the OHWM. Below the OHWM the slopes are gradually sloped within 80 feet of the OHWM to a max depth of approximately 15 ft below the OHWM. b. What is the steepest slope on the site (approximate percent slope)? [help] Approximately 90% along the steep shoreline slope. 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. [help] In general, shoreline soils consists of riprap for the entire stretch of the park. The riprap extends from the top of the bank to the toe of the slope. Above the top of the bank, the soils consists of topsoil and lawngrass. d. Are there surface indications or history of unstable soils in the immediate vicinity? If so, describe. [help] The existing slope has been armored in the past with riprap (angular rock) and there are no indications of unstable soils. e. Describe the purpose, type, total area, and approximate quantities and total affected area of any filling, excavation, and grading proposed. Indicate source of fill. [help] The proposed project will replace the existing docks at the exact location of the existing docks. The only fill that will be placed as part of the project will be concrete on the existing concrete abutments. Each of the existing concrete abutments will be leveled off with reinforced concrete to allow the concrete to be flush with the existing onshore walkway. The existing concrete abutments each have stairs providing access from the shoreline trail to the existing gangways. The placement of concrete will eliminate the stairs to make the public docks ADA compliant. In total, concrete will be placed over approximately 320 sq ft; however, the concrete will be installed over the existing concrete abutments. A total of 15.2 cubic yards of concrete will be installed. f. Could erosion occur as a result of clearing, construction, or use? If so, generally describe. [help] No erosion will occur as a result of the proposed project. g.

Is the site part of a migration route? If so, explain. [help] Yes. The area is also used as a migration route by waterfowl. d. Proposed measures to preserve or enhance wildlife, if any: [help] The proposed project will have no negative impact on water quality, water supply, recreation, or aesthetics of the Columbia River. The proposed project will replace the existing deteriorating public access docks. The entire project would occur in a heavily developed and utilized portion of the shoreline within the City of Pateros. Potential impacts to fish and aquatic life would be sufficiently minimized by the conformance with current regulation for overwater structures on the Columbia River developed by the USACE and NMFS. The proposed project involves avoidance and minimization measures in the float design, such as utilizing grated deck surface with at least 60% light transference, floats constructed with at least 50% open area, limiting the number of piles required to safely anchor the floats, and utilizing pile caps to prevent perching of piscivorous birds. Further, the proposed project will replace existing permitted docks. In addition to the design consideration, the project will also conform with the following avoidance and minimization measures: The project would occur during the approved in-water work window (July 16 through February 28 with pile driving only occurring between October 1 through February 28) for the protection of migrating juvenile salmonids. Extreme care would be taken to prevent any petroleum products, chemicals, or other toxic or deleterious materials from entering the water. If a spill were to occur, work would be stopped immediately, steps would be taken to contain the material, and appropriate agency notifications would be made. During demolition of the docks and piling a silt curtain will be installed around the work area to minimize turbidity and to ensure that no debris leaves the work area. All equipment operating waterward of the OHWM would be inspected daily for fluid leaks. Leaking equipment would be repaired prior to resuming operation. Uncured cast-in-place concrete in the upland would not be allowed to enter the water. The Contractor would develop and implement a site-specific spill prevention, containment, and control (SPCC) plan, and is responsible for containment and removal of any toxicants released. All exposed or disturbed areas, including upland staging areas, would be stabilized to prevent erosion. All erosion control devices would be inspected during construction to ensure that they are working adequately. Grated surfaces would not be used for storage or other purposes that would reduce natural light penetration through the structure. A bubble curtain would be used as a sound attenuation measure during impact pile driving.

11 Shoreline planting efforts would be completed in the first planting season following float installation. Planting would be completed no later than the first April 15 following construction. Overall, the proposed project will result in no adverse impacts the Columbia River. e. List any invasive animal species known to be on or near the site. None. 6. Energy and natural resources a. What kinds of energy (electric, natural gas, oil, wood stove, solar) will be used to meet the completed project's energy needs? Describe whether it will be used for heating, manufacturing, etc. [help] No energy will be required to meet the completed projects need. b. Would your project affect the potential use of solar energy by adjacent properties? If so, generally describe. [help] No. c. What kinds of energy conservation features are included in the plans of this proposal? List other proposed measures to reduce or control energy impacts, if any: [help] None proposed. 7.

None known 4) Describe special emergency services that might be required. None required. 5) Proposed measures to reduce or control environmental health hazards, if any: Environmental health hazards are not expected through the development of this project. Only approved construction materials will be used in construction of this project. b. Noise 1) What types of noise exist in the area which may affect your project (for example: traffic, equipment, operation, other)? [help] No noise exists in the surrounding area that would affect the project. 2) What types and levels of noise would be created by or associated with the project on a short-term or a long-term basis (for example: traffic, construction, operation, other)? Indicate what hours noise would come from the site. [help] Typical construction equipment operation (excavator and truck noise) will occur at the site. This noise will only occur during construction activities and will be limited to daylight hours. Long term use will be the same as the existing level of noise. 3) Proposed measures to reduce or control noise impacts, if any: [help] None proposed. 8. Land and shoreline use a. What is the current use of the site and adjacent properties? Will the proposal affect current land uses on nearby or adjacent properties? If so, describe. [help] The current use of the property is a public park that provide river access and temporary moorage within the City of Pateros. The uses of the adjacent properties are either commercial or public use (park). The proposed project will have no impact on these uses, rather the proposed project will result in the continued safe use of the docks.

13 b. Has the project site been used as working farmlands or working forest lands? If so, describe. How much agricultural or forest land of long-term commercial significance will be converted to other uses as a result of the proposal, if any?
