HomeMy WebLinkAboutECF_Environmental_Checklist_190917_V1.pdfSEPA Environmental checklist (WAC 197-11-960) July 2016 Page 1 of 16 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.

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 Canopy project consists of 5 parcels that equals approximately 10 acres. The project will be a Preliminary Plat/ Planned Urban Development consisting of 55 new lots where some of the lots will be accessed by an alley. 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.

General description of the site: (circle one): Flat, rolling, hilly, steep slopes, mountainous, other _____________ b. What is the steepest slope on the site (approximate percent slope)? 65% is approximately the greatest slope outside of the developed area. 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. The site consists of topsoil, sandy silt, gravel, silt and sand, See Geotechnical Report for detailed information. d. Are there surface indications or history of unstable soils in the immediate vicinity? If so, describe. None to our knowledge 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. The affected area is approximately 7.1 acres. The project will have 70,230 CY of cut and 16,395 CY of fill. Location of fill material has not been determined but it will be from an approved location. f. Could erosion occur as a result of clearing, construction, or use? If so, generally describe. Yes, erosion could occur, however the use of BMP’s will mitigate possible erosive situations should they occur and limiting earthwork to seasonally drier periods, typically April 1 to October 31 will help to mitigate it. g.

What types of emissions to the air would result from the proposal during construction, operation, and maintenance when the project is completed? If any, generally describe and give approximate quantities if known. During construction, there will be increased exhaust and dust particle emissions. After construction, the principle source of emissions will be from automobile traffic, lawn equipment, and other behavior typical of maintenance of a mixed-use/residential uses. b. Are there any off-site sources of emissions or odor that may affect your proposal? If so, generally describe. Off-site sources of emissions are those typical of the residential neighborhoods that surround this site, such as automobile emissions from traffic on adjacent roadways and fireplace emissions from nearby houses. c. Proposed measures to reduce or control emissions or other impacts to air, if any: Construction impacts will not be significant and can be controlled by several methods: watering or using dust suppressants on areas of exposed soils, washing truck wheels before leaving the site, and maintaining gravel construction entrances. Automobile and fireplace emission standards are regulated by the State of Washington. The site has been included in a “No Burn Zone” by the Puget Sound Air Pollution Control Agency which went into effect on September 1, 1992. No land clearing or residential yard debris fires would be permitted on-site, nor in the surrounding neighborhood in accordance with the regulation. 3. Water [help] a. Surface Water: [help] 1) Is there any surface water body on or in the immediate vicinity of the site (including year-round and seasonal streams, saltwater, lakes, ponds, wetlands)?

Where will this water flow? Will this water flow into other waters? If so, describe. Runoff will be generated by impervious surfaces such as driveways, roads, sidewalks, roofs and patios. This stormwater will be collected and conveyed to two proposed storm facilities located on the west portion of the site. 2) Could waste materials enter ground or surface waters? If so, generally describe. This would be very unlikely. The only materials that could enter ground or surface waters would be those associated with automobile discharges and yard and garden preparations. Pollutants generated during construction include suspended solids and trace petroleum hydrocarbons. Following construction, the two primary sources of pollutants include roadways and landscaping chemicals. Roadway runoff includes trace petroleum hydrocarbons and trace metals. Landscaping chemicals include fertilizers, pesticides and herbicides. 3) Does the proposal alter or otherwise affect drainage patterns in the vicinity of the site? If so, describe. No. d.
